+				 7/1
+				 ---

+	 autoconf set the value itself in the Makefile
+	- removed a stray `-' before $(RANLIB) in the `install' recipe
+
+doc/Makefile.in
+	- add a VPATH assignment so the documentation is not remade if it's
+	 already up-to-date in the distribution
+
+configure.in
+	- call AC_SUBST(LOCAL_LDFLAGS), since Makefile.in contains
+	 @LOCAL_LDFLAGS@
+
+				 7/9
+				 ---
+
+config.h.in
+	- add define lines for STRUCT_WINSIZE_IN_SYS_IOCTL and
+	 STRUCT_WINSIZE_IN_TERMIOS

+	- add `install-shared' and `uninstall-shared' targets
+
+				 8/4
+				 ---

+	- install and uninstall libhistory.a in the `install' and
+	 `uninstall' targets
+
+				 9/4
+				 ---
+configure.in
+	- bumped LIBVERSION up to 2.1.1, indicating that this is patch
+	 level 1 to release 2.1
+
+
+				 9/16
+				 ----

+	- `make distclean' now descends into the `examples' subdir
+
+doc/Makefile.in
+	- the `distclean' and `maintainer-clean' targets should remove
+	 Makefile
+

+	- added the various clean targets
+
+				 4/2
+				 ---
+configure.in
+	- bumped LIBVERSION up to 2.2
+
+				 4/18
+				 ----
+readline-2.2 released
+
+				 4/20
+				 ----
+Makefile.in
+	- make `libhistory.a' a dependency of `install'
+	- fixed a typo in the recipe for `install' that copied libreadline.a
+	 to libhistory.old right after installing it
+
+				 4/27
+				 ----
+doc/Makefile.in
+	- install {readline,history}.info out of the source directory if
+	 they are not found in the current (build) directory -- only an
+	 issue if the libraries are built in a different directory than
+	 the source directory
+
+				 5/1
+				 ---
+support/shobj-conf
+	- script from the bash distribution to do shared object and library
+	 configuration
+
+shlib/Makefile.in
+	- new directory and makefile to handle building shared versions of
+	 libreadline and libhistory, controlled by support/shobj-conf
+
+				 5/7
+				 ---
+doc/Makefile.in
+	- set SHELL to /bin/sh, rather than relying on make to be correct
+
+				 5/14
+				 ----
+savestring.c
+	- new file, moved from shell.c, for backwards compatibility
+
+Makefile.in, shlib/Makefile.in
+	- make sure savestring.c is compiled and added to libreadline and
+	 libhistory
+
+THERE ARE NO MORE #ifdef SHELL LINES IN THE C SOURCE FILES.
+
+				 5/15
+				 ----
+README
+	- updated description of shared library creation for the new scheme

+THERE ARE NO MORE #ifdef SHELL LINES IN ANY OF THE SOURCE FILES.
+
+Makefile.in
+	- bumped SHLIB_MAJOR up to 4 since we've augmented the library
+	 API
+	- rlconf.h is now one of the installed headers, so applications can
+	 find out whether things like vi-mode are available in the installed
+	 libreadline
+
+				 5/20
+				 ----
+configure.in
+	- changed RL_LIBRARY_VERSION to 4.0 to match the version of the

+				 ---
+rlstdc.h
+	- new file
+
+Makefile.in
+	- rlstdc.h is now one of the installed headers
+
+				 8/3
+				 ---
+shlib/Makefile.in
+	- made the suffix rule that creates xx.so from xx.c write the
+	 compiler output to `a.o', which is then mv'd to xx.so, because
+	 some compilers (Sun WSpro 4.2, for example) don't allow any
+	 suffixes other than `.o' for `cc -c' (not even `a.out')
+
+				 9/15
+				 ----
+
+Makefile.in
+	- AR and ARFLAGS are now substituted by configure, used in recipes
+	 that build the libraries

+
+				 10/5
+				 ----
+Makefile.in
+	- removed savestring.o from object file list
+
+				 10/28
+				 -----
+shlib/Makefile.in
+	- don't use a fixed filename in the .c.so suffix rule to avoid
+	 problems with parallel makes
+
+				 12/21
+				 -----
+support/shlib-install
+	- new script to install shared readline and history libraries
+
+shlib/Makefile.in
+	- changed to call shlib-install for install and uninstall targets
+
+readline-4.0-beta1 frozen
+
+				 12/22
+				 -----
+configure.in
+	- call AC_SUBST for SHOBJ_XLDFLAGS and SHLIB_LIBS
+
+shlib/Makefile.in
+	- SHOBJ_XLDFLAGS and SHLIB_LIBS are now substituted by configure
+	- add $(SHLIB_LIBS) at end of command line that builds the shared
+	 libraries (currently needed only by AIX 4.2)
+
+				 12/31
+				 -----
+MANIFEST, MANIFEST.doc
+	- the TOC html files are no longer generated and no longer part of
+	 the distribution
+
+				 2/18/1999
+				 ---------

+	 files are no longer created
+
+examples/Makefile.in
+	- remove `*.exe' in clean target for MS-DOS
+
+Makefile.in
+	- make `readline' target depend on ./libreadline.a
+	- configure now substitutes TERMCAP_LIB into Makefile.in
+	- use ${TERMCAP_LIB} instead of -ltermcap in recipe for `readline'
+	- clean target now removes readline and readline.exe in case they
+	 get built
+
+configure.in
+	- use `pwd.exe' to set BUILD_DIR on MS-DOS DJGPP
+
+				 3/15
+				 ----
+support/shlib-install
+	- Irix 5.x and Irix 6.x should install shared libraries like Solaris 2
+	- changes for installing on hp-ux 101.x
+
+				 3/23
+				 ----
+configure.in
+	- make sure that the $CC argument to shobj-conf is quoted
+
+				 4/8
+				 ---
+
+xmalloc.h, rlprivate.h, rlshell.h
+	- new files
+
+Makefile.in,shlib/Makefile.in
+	- add dependencies on xmalloc.h, rlshell.h
+	- add xmalloc.h, rlprivate.h, rlshell.h to list of header files
+
+MANIFEST
+	- add xmalloc.h, rlprivate.h, rlshell.h
+
+				 4/9
+				 ---
+Makefile.in,shlib/Makefile.in
+	- add dependencies on rlprivate.h
+
+				 4/13
+				 ----
+doc/Makefile.in
+	- add variable, PSDVI, which is the desired resolution of the
+	 generated postscript files. Set to 300 because I don't have
+	 any 600-dpi printers
+	- set LANGUAGE= before calling makeinfo, so messages are in English
+	- add rluserman.{info,dvi,ps,html} to appropriate variables
+	- add rules to create rluserman.{info,dvi,ps,html}
+	- install and uninstall rluserman.info, but don't update the directory
+	 file in $(infodir) yet
+
+MANIFEST
+	- add doc/rluserman.{texinfo,info,dvi,ps,html}
+
+				 4/30
+				 ----
+configure.in
+	- updated library version to 4.1
+
+				 5/3
+				 ---
+configure.in
+	- SHLIB_MAJOR and SHLIB_MINOR shared library version numbers are
+	 constructed from $LIBRARY_VERSION and substituted into Makefiles
+
+				 5/5
+				 ---
+support/shlib-install
+	- OSF/1 installs shared libraries like Solaris
+
+Makefile.in
+	- broke the header file install and uninstall into two new targets:
+	 install-headers and uninstall-headers
+	- install and uninstall depend on install-headers and uninstall-headers
+	 respectively
+	- changed install-shared and uninstall-shared targets to depend on
+	 install-headers and uninstall-headers, respectively, so users may
+	 choose to install only the shared libraries. I'm not sure about
+	 the uninstall one yet -- maybe it should check whether or not
+	 the static libraries are installed and not remove the header files
+	 if they are
+
+				 9/3
+				 ---
+configure.in, config.h.in
+	- added test for memmove (for later use)
+	- changed version to 4.1-beta1
+
+				 9/13
+				 ----
+examples/rlfe.c
+	- Per Bothner's `rlfe' readline front-end program
+
+examples/Makefile.in
+	- added rules to build rlfe
+
+				 9/21
+				 ----
+support/shlib-install
+	- changes to handle FreeBSD-3.x elf or a.out shared libraries, which
+	 have different semantics and need different naming conventions
+
+				 1/24/2000
+				 ---------
+doc/Makefile.in
+	- remove *.bt and *.bts on `make clean'
+
+				 2/4
+				 ---
+
+
+configure.in
+	- changed LIBVERSION to 4.1-beta5
+
+				 3/17/2000
+				 ---------
+readline-4.1 released
+
+				 3/23
+				 ----
+Makefile.in
+	- remove the `-t' argument to ranlib in the install recipe; some
+	 ranlibs don't have it and attempt to create a file named `-t'
+
+				 3/27
+				 ----
+support/shlib-install
+	- install shared libraries unwritable by anyone on HP-UX
+	- changed symlinks to relative pathnames on all platforms
+
+shlib/Makefile.in
+	- added missing `includedir' assignment, substituted by configure
+
+Makefile.in
+	- added missing @SET_MAKE@ so configure can set $MAKE appropriately
+
+configure.in
+	- add call to AC_PROG_MAKE_SET
+
+				 8/30
+				 ----
+shlib/Makefile.in
+	- change the soname bound into the shared libraries, so it includes
+	 only the major version number. If it includes the minor version,
+	 programs depending on it must be rebuilt (which may or may not be
+	 a bad thing)
+
+				 9/6
+				 ---
+examples/rlfe.c
+	- add -l option to log input and output (-a option appends to logfile)
+	- add -n option to set readline application name
+	- add -v, -h options for version and help information
+	- change a few things because getopt() is now used to parse arguments
+
+				 9/12
+				 ----
+support/shlib-install
+	- fix up the libname on HPUX 11
+
+				 10/18
+				 -----
+configure.in
+	- changed library version to 4.2-alpha
+
+				 10/30
+				 -----
+configure.in
+	- add -fsigned-char to LOCAL_CFLAGS for Linux running on the IBM
+	 S/390
+
+Makefile.in
+	- added new file, rltypedefs.h, installed by default with `make install'
+
+				 11/2
+				 ----
+compat.c
+	- new file, with backwards-compatibility function definitions
+
+Makefile.in,shlib/Makefile.in
+	- make sure that compat.o/compat.so are built and linked apppropriately
+
+support/shobj-conf
+	- picked up bash version, which means that shared libs built on
+	 linux and BSD/OS 4.x will have an soname that does not include
+	 the minor version number
+
+				 11/13
+				 -----
+examples/rlfe.c
+	- rlfe can perform filename completion for relative pathnames in the
+	 inferior process's context if the OS supports /proc/PID/cwd (linux
+	 does it OK, Solaris is slightly warped, none of the BSDs have it)
+
+				11/17/2000
+				----------
+readline-4.2-alpha released
+
+				 11/27
+				 -----
+Makefile.in,shlib/Makefile.in
+	- added dependencies for rltypedefs.h
+
+shlib/Makefile.in

@@ -0,0 +1,1827 @@
+This document details the changes between this version, readline-8.1, and
+the previous version, readline-8.0.
+
+1. Changes to Readline
+
+a. There are a number of fixes that were found as the result of fuzzing with
+ random input.
+
+b. Changed the revert-all-at-newline behavior to make sure to start at the end
+ of the history list when doing it, instead of the line where the user hit
+ return.
+
+c. When parsing `set' commands from the inputrc file or an application, readline
+ now allows trailing whitespace.
+
+d. Fixed a bug that left a file descriptor open to the history file if the
+ file size was 0.
+
+e. Fixed a problem with binding key sequences containing meta characters.
+
+f. Fixed a bug that caused the wrong line to be displayed if the user tried to
+ move back beyond the beginning of the history list, or forward past the end
+ of the history list.
+
+g. If readline catches SIGTSTP, it now sets a hook that allows the calling
+ application to handle it if it desires.
+
+h. Fixed a redisplay problem with a prompt string containing embedded newlines.
+
+i. Fixed a problem with completing filenames containing invalid multibyte
+ sequences when case-insensitive comparisons are enabled.
+
+j. Fixed a redisplay problem with prompt strings containing invisible multibyte
+ characters.
+
+k. Fixed a problem with multibyte characters mapped to editing commands that
+ modify the search string in incremental search.
+
+l. Fixed a bug with maintaining the key sequence while resolving a bound
+ command in the presence of ambiguous sequences (sequences with a common
+ prefix), in most cases while attempting to unbind it.
+
+m. Fixed several buffer overflows found as the result of fuzzing.
+
+n. Reworked backslash handling when translating key sequences for key binding
+ to be more uniform and consistent, which introduces a slight backwards
+ incompatibility.
+
+o. Fixed a bug with saving the history that resulted in errors not being
+ propagated to the calling application when the history file is not writable.
+
+p. Readline only calls chown(2) on a newly-written history file if it really
+ needs to, instead of having it be a no-op.
+
+q. Readline now behaves better when operate-and-get-next is used when the
+ history list is `full': when there are already $HISTSIZE entries.
+
+r. Fixed a bug that could cause vi redo (`.') of a replace command not to work
+ correctly in the C or POSIX locale.
+
+s. Fixed a bug with vi-mode digit arguments that caused the last command to be
+ set incorrectly. This prevents yank-last-arg from working as intended, for
+ example.
+
+t. Make sure that all undo groups are closed when leaving vi insertion mode. 
+
+u. Make sure that the vi-mode `C' and `c' commands enter insert mode even if
+ the motion command doesn't have any effect.
+
+v. Fixed several potential memory leaks in the callback mode context handling.
+
+w. If readline is handling a SIGTTOU, make sure SIGTTOU is blocked while
+ executing the terminal cleanup code, since it's no longer run in a signal
+ handling context.
+
+x. Fixed a bug that could cause an application with an application-specific 
+ redisplay function to crash if the line data structures had not been
+ initialized.
+
+y. Terminals that are named "dumb" or unknown do not enable bracketed paste
+ by default.
+
+z. Ensure that disabling bracketed paste turns off highlighting the incremental
+ search string when the search is successful.
+
+2. New Features in Readline
+
+a. If a second consecutive completion attempt produces matches where the first
+ did not, treat it as a new completion attempt and insert a match as
+ appropriate.
+
+b. Bracketed paste mode works in more places: incremental search strings, vi
+ overstrike mode, character search, and reading numeric arguments.
+
+c. Readline automatically switches to horizontal scrolling if the terminal has
+ only one line.
+
+d. Unbinding all key sequences bound to a particular readline function now
+ descends into keymaps for multi-key sequences.
+
+e. rl-clear-display: new bindable command that clears the screen and, if
+ possible, the scrollback buffer (bound to emacs mode M-C-l by default).
+
+f. New active mark and face feature: when enabled, it will highlight the text
+ inserted by a bracketed paste (the `active region') and the text found by
+ incremental and non-incremental history searches. This is tied to bracketed
+ paste and can be disabled by turning off bracketed paste.
+
+g. Readline sets the mark in several additional commands.
+
+h. Bracketed paste mode is enabled by default. There is a configure-time
+ option (--enable-bracketed-paste-default) to set the default to on or off.
+
+i. Readline tries to take advantage of the more regular structure of UTF-8
+ characters to identify the beginning and end of characters when moving
+ through the line buffer.
+
+j. The bindable operate-and-get-next command (and its default bindings) are
+ now part of readline instead of a bash-specific addition.
+
+k. The signal cleanup code now blocks SIGINT while processing after a SIGINT. 
+
+-------------------------------------------------------------------------------
+This document details the changes between this version, readline-8.0, and the
+previous version, readline-7.0.
+
+1. Changes to Readline
+
+a. Added a guard to prevent nested macros from causing an infinite expansion
+ loop.
+
+b. Instead of allocating enough history list entries to hold the maximum list
+ size, cap the number allocated initially.
+ 
+c. Added a strategy to avoid allocating huge amounts of memory if a block of
+ history entries without timestamps occurs after a block with timestamps.
+
+d. Added support for keyboard timeouts when an ESC character is the last
+ character in a macro.
+
+e. There are several performance improvements when in a UTF-8 locale.
+
+f. Readline does a better job of preserving the original set of blocked
+ signals when using pselect() to wait for input.
+
+g. Fixed a bug that caused multibyte characters in macros to be mishandled.
+
+h. Fixed several bugs in the code that calculates line breaks when expanding
+ prompts that span several lines, contain multibyte characters, and contain
+ invisible character seqeuences.
+
+i. Fixed several bugs in cursor positioning when displaying lines with prompts
+ containing invisible characters and multibyte characters.
+
+j. When performing case-insensitive completion, Readline no longer sorts the
+ list of matches unless directed to do so.
+
+k. Fixed a problem with key sequences ending with a backslash.
+
+l. Fixed out-of-bounds and free memory read errors found via fuzzing.
+
+m. Fixed several cases where the mark was set to an invalid value.
+
+n. Fixed a problem with the case-changing operators in the case where the
+ lower and upper case versions of a character do not have the same number
+ of bytes.
+
+o. Handle incremental and non-incremental search character reads returning EOF.
+
+p. Handle the case where a failing readline command at the end of a multi-key
+ sequence could be misinterpreted.
+
+q. The history library now prints a meaningful error message if the history
+ file isn't a regular file.
+
+r. Fixed a problem with vi-mode redo (`.') on a command when trying to replace
+ a multibyte character.
+
+s. The key binding code now attempts to remove a keymap if a key unbinding
+ leaves it empty.
+
+t. Fixed a line-wrapping issue that caused problems for some terminal
+ emulators.
+
+u. If there is a key bound to the tty's VDISCARD special character, readline
+ disables VDISCARD while it is active.
+
+v. Fixed a problem with exiting bracketed paste mode on terminals that assume
+ the bracketed paste mode character sequence contains visible characters.
+
+w. Fixed a bug that could cause a key binding command to refer to an
+ uninitialized variable.
+
+x. Added more UTF-8-specific versions of multibyte functions, and optimized
+ existing functions if the current locale uses UTF-8 encoding.
+
+y. Fixed a problem with bracketed-paste inserting more than one character and
+ interacting with other readline functions.
+
+z. Fixed a bug that caused the history library to attempt to append a history
+ line to a non-existent history entry.
+
+aa. If using bracketed paste mode, output a newline after the \r that is the
+ last character of the mode disable string to avoid overwriting output.
+
+bb. Fixes to the vi-mode `b', `B', `w', `W', `e', and `E' commands to better
+ handle multibyte characters.
+
+cc. Fixed a redisplay problem that caused an extra newline to be generated on
+ accept-line when the line length is exactly the screenwidth.
+
+dd. Fixed a bug with adding multibyte characters to an incremental search
+ string.
+
+ee. Fixed a bug with redoing text insertions in vi mode.
+
+ff. Fixed a bug with pasting text into an incremental search string if bracketed
+ paste mode is enabled. ESC cannot be one of the incremental search
+ terminator characters for this to work.
+
+gg. Fixed a bug with anchored search patterns when performing searches in vi
+ mode.
+
+2. New Features in Readline
+
+a. Non-incremental vi-mode search (`N', `n') can search for a shell pattern, as
+ Posix specifies (uses fnmatch(3) if available).
+
+b. There are new `next-screen-line' and `previous-screen-line' bindable
+ commands, which move the cursor to the same column in the next, or previous,
+ physical line, respectively.
+
+c. There are default key bindings for control-arrow-key key combinations.
+
+d. A negative argument (-N) to `quoted-insert' means to insert the next N
+ characters using quoted-insert.
+
+e. New public function: rl_check_signals(), which allows applications to
+ respond to signals that readline catches while waiting for input using
+ a custom read function.
+
+f. There is new support for conditionally testing the readline version in an
+ inputrc file, with a full set of arithmetic comparison operators available.
+
+g. There is a simple variable comparison facility available for use within an
+ inputrc file. Allowable operators are equality and inequality; string
+ variables may be compared to a value; boolean variables must be compared to
+ either `on' or `off'; variable names are separated from the operator by
+ whitespace.
+
+h. The history expansion library now understands command and process
+ substitution and extended globbing and allows them to appear anywhere in a
+ word.
+
+i. The history library has a new variable that allows applications to set the
+ initial quoting state, so quoting state can be inherited from a previous
+ line.
+
+j. Readline now allows application-defined keymap names; there is a new public
+ function, rl_set_keymap_name(), to do that.
+
+k. The "Insert" keypad key, if available, now puts readline into overwrite
+ mode.
+
+-------------------------------------------------------------------------------
+This document details the changes between this version, readline-7.0, and the
+previous version, readline-6.3.
+
+1. Changes to Readline
+
+a. A bug that caused vi-mode `.' to be unable to redo `c', `d', and `y'
+ commands with modifiers was fixed.
+
+b. Fixed a bug that caused callback mode to dump core when reading a
+ multiple-key sequence (e.g., arrow keys).
+
+c. Fixed a bug that caused the redisplay code to erase some of the line when
+ using horizontal scrolling with incremental search.
+
+d. Readline's input handler now performs signal processing if read(2) is
+ interrupted by SIGALRM or SIGVTALRM.
+
+e. Fixed a problem with revert-all-at-newline freeing freed memory.
+
+f. Clarified the documentation for the history_quotes_inhibit_expansion
+ variable to note that it inhibits scanning for the history comment
+ character and that it only affects double-quoted strings.
+
+g. Fixed an off-by-one error in the prompt printed when performing searches.
+
+h. Use pselect(2), if available, to wait for input before calling read(2), so
+ a SIGWINCH can interrupt it, since it doesn't interrupt read(2).
+
+i. Some memory leaks caused by signals interrupting filename completion have
+ been fixed.
+
+j. Reading EOF twice on a non-empty line causes EOF to be returned, rather
+ than the partial line. This can cause partial lines to be executed on
+ SIGHUP, for example.
+
+k. Fixed a bug concerning deleting multibyte characters from the search
+ string while performing an incremental search.
+
+l. Fixed a bug with tilde expanding directory names in filename completion.
+
+m. Fixed a bug that did not allow binding sequences beginning with a `\'.
+
+n. Fixed a redisplay bug involving incorrect line wrapping when the prompt
+ contains a multibyte character in the last screen column.
+
+o. Fixed a bug that caused history expansion to disregard characters that are
+ documented to delimit a history event specifier without requiring `:'.
+
+p. Fixed a bug that could cause reading past the end of a string when reading
+ the value when binding the set of isearch terminators.
+
+q. Fixed a bug that caused readline commands that depend on knowing which 
+ key invoked them to misbehave when dispatching key sequences that are
+ prefixes of other key bindings. 
+
+r. Paren matching now works in vi insert mode.
+
+s. Colored completion prefixes are now displayed using a different color, less
+ likely to collide with files.
+
+t. Fixed a bug that caused vi-mode character search to misbehave when
+ running in callback mode.
+
+u. Fixed a bug that caused output to be delayed when input is coming from a
+ macro in vi-mode.
+
+v. Fixed a bug that caused the vi-mode `.' command to misbehave when redoing
+ a multi-key key sequence via a macro.
+
+w. Fixed a bug that caused problems with applications that supply their own
+ input function when performing completion.
+
+x. When read returns -1/EIO when attempting to read a key, return an error
+ instead of line termination back to the caller.
+
+y. Updated tty auditing feature based on patch from Red Hat.
+
+z. Fixed a bug that could cause the history library to crash on overflows
+ introduced by malicious editing of timestamps in the history file.
+
+aa. The history file writing functions only attempt to create and use a backup
+ history file if the history file exists and is a regular file.
+
+bb. Fixed an out-of-bounds read in readline's internal tilde expansion interface.
+
+cc. Fixed several redisplay bugs with prompt strings containing multibyte
+ and non-visible characters whose physical length is longer than the screen
+ width.
+
+dd. Fixed a redisplay bug with prompt strings containing invisible characters
+ whose physical length exceeds the screen width and using incremental search.
+
+ee. Readline prints more descriptive error messages when it encounters errors
+ while reading an inputrc file.
+
+ff. Fixed a bug in the character insertion code that attempts to optimize
+ typeahead when it reads a character that is not bound to self-insert and
+ resets the key sequence state.
+
+gg. When refreshing the line as the result of a key sequence, Readline attempts
+ to redraw only the last line of a multiline prompt.
+
+hh. Fixed an issue that caused completion of git commands to display
+ incorrectly when using colored-completion-prefix.
+
+ii. Fixed several redisplay bugs having to do with multibyte characters and
+ invisible characters in prompt strings.
+
+jj. Fixed a bug that caused mode strings to be displayed incorrectly if the
+ prompt was shorter than the mode string.
+
+2. New Features in Readline
+
+a. The history truncation code now uses the same error recovery mechansim as
+ the history writing code, and restores the old version of the history file
+ on error. The error recovery mechanism handles symlinked history files.
+
+b. There is a new bindable variable, `enable-bracketed-paste', which enables
+ support for a terminal's bracketed paste mode.
+
+c. The editing mode indicators can now be strings and are user-settable
+ (new `emacs-mode-string', `vi-cmd-mode-string' and `vi-ins-mode-string'
+ variables). Mode strings can contain invisible character sequences.
+ Setting mode strings to null strings restores the defaults.
+
+d. Prompt expansion adds the mode string to the last line of a multi-line
+ prompt (one with embedded newlines).
+
+e. There is a new bindable variable, `colored-completion-prefix', which, if
+ set, causes the common prefix of a set of possible completions to be
+ displayed in color.
+
+f. There is a new bindable command `vi-yank-pop', a vi-mode version of emacs-
+ mode yank-pop.
+
+g. The redisplay code underwent several efficiency improvements for multibyte
+ locales.
+
+h. The insert-char function attempts to batch-insert all pending typeahead
+ that maps to self-insert, as long as it is coming from the terminal.
+
+i. rl_callback_sigcleanup: a new application function that can clean up and
+ unset any state set by readline's callback mode. Intended to be used
+ after a signal.
+
+j. If an incremental search string has its last character removed with DEL, the
+ resulting empty search string no longer matches the previous line.
+
+k. If readline reads a history file that begins with `#' (or the value of
+ the history comment character) and has enabled history timestamps, the history
+ entries are assumed to be delimited by timestamps. This allows multi-line
+ history entries.
+
+l. Readline now throws an error if it parses a key binding without a terminating
+ `:' or whitespace.
+
+m. The default binding for ^W in vi mode now uses word boundaries specified
+ by Posix (vi-unix-word-rubout is bindable command name).
+
+n. rl_clear_visible_line: new application-callable function; clears all
+ screen lines occupied by the current visible readline line.
+
+o. rl_tty_set_echoing: application-callable function that controls whether
+ or not readline thinks it is echoing terminal output.
+
+p. Handle >| and strings of digits preceding and following redirection
+ specifications as single tokens when tokenizing the line for history
+ expansion.
+
+q. Fixed a bug with displaying completions when the prefix display length
+ is greater than the length of the completions to be displayed.
+
+r. The :p history modifier now applies to the entire line, so any expansion
+ specifying :p causes the line to be printed instead of expanded.
+
+s. New application-callable function: rl_pending_signal(): returns the signal
+ number of any signal readline has caught but not yet handled.
+ 
+t. New application-settable variable: rl_persistent_signal_handlers: if set
+ to a non-zero value, readline will enable the readline-6.2 signal handler
+ behavior in callback mode: handlers are installed when
+ rl_callback_handler_install is called and removed removed when a complete
+ line has been read.
+
+-------------------------------------------------------------------------------
+This document details the changes between this version, readline-6.3, and the
+previous version, readline-6.2.
+
+1. Changes to Readline
+
+a. Fixed a bug that did not allow the `dd', `cc', or `yy' vi editing mode
+ commands to work on the entire line.
+
+b. Fixed a bug that caused redisplay problems with prompts longer than 128
+ characters and history searches.
+
+c. Fixed a bug that caused readline to try and run code to modify its idea
+ of the screen size in a signal handler context upon receiving a SIGWINCH.
+
+d. Fixed a bug that caused the `meta' key to be enabled beyond the duration
+ of an individual call top readline().
+ 
+e. Added a workaround for a wcwidth bug in Mac OS X that caused readline's
+ redisplay to mishandle zero-width combining characters.
+
+f. Fixed a bug that caused readline to `forget' part of a key sequence when
+ a multiple-key sequence caused it to break out of an incremental search.
+
+g. Fixed bugs that caused readline to execute code in a signal handler
+ context if interrupted while reading from the file system during completion.
+
+h. Fixed a bug that caused readline to `forget' part of a key sequence when
+ reading an unbound multi-character key sequence.
+
+i. Fixed a bug that caused Readline's signal handlers to be installed beyond
+ the bounds of a single call to readline().
+
+j. Fixed a bug that caused the `.' command to not redo the most recent `R'
+ command in vi mode.
+
+k. Fixed a bug that caused ignoring case in completion matches to result in
+ readline using the wrong match.
+
+l. Paren matching now works in vi insert mode.
+
+m. Fix menu-completion to make show-all-if-ambiguous and menu-complete-display-prefix
+ work together.
+
+n. Fixed a bug that didn't allow the `cc', `dd', or `yy' commands to be redone
+ in vi editing mode.
+
+o. Fixed a bug that caused the filename comparison code to not compare
+ multibyte characters correctly when using case-sensitive or case-mapping
+ comparisons.
+
+p. Fixed the input reading loop to call the input hook function only when there
+ is no terminal input available.
+
+q. Fixed a bug that caused binding a macro to a multi-character key sequence
+ where the sequence and macro value share a common prefix to not perform
+ the macro replacement.
+
+r. Fixed several redisplay errors with multibyte characters and prompts
+ containing invisible characters when using horizontal scrolling.
+
+s. Fixed a bug that caused redisplay errors when trying to overwrite
+ existing characters using multibyte characters.
+
+t. Fixed a bug in vi mode that caused the arrow keys to set the saved last
+ vi-mode command to the wrong value.
+
+u. Fixed a bug that caused double-quoted strings to be scanned incorrectly
+ when being used as the value of a readline variable assignment.
+
+v. Fixed a bug with vi mode that prevented `.' from repeating a command
+ entered on a previous line (command).
+
+w. Fixed a bug that could cause completion to core dump if it was interrupted
+ by a signal.
+
+x. Fixed a bug that could cause readline to crash and seg fault attempting to
+ expand an empty history entry.
+
+y. Fixed a bug that caused display problems with multi-line prompts containing
+ invisible characters on multiple lines.
+ 
+z. Fixed a bug that caused effects made by undoing changes to a history line to
+ be discarded.
+
+2. New Features in Readline
+
+a. Readline is now more responsive to SIGHUP and other fatal signals when
+ reading input from the terminal or performing word completion but no
+ longer attempts to run any not-allowable functions from a signal handler
+ context.
+
+b. There are new bindable commands to search the history for the string of
+ characters between the beginning of the line and the point
+ (history-substring-search-forward, history-substring-search-backward)
+
+c. Readline allows quoted strings as the values of variables when setting
+ them with `set'. As a side effect, trailing spaces and tabs are ignored
+ when setting a string variable's value.
+
+d. The history library creates a backup of the history file when writing it
+ and restores the backup on a write error.
+
+e. New application-settable variable: rl_filename_stat_hook: a function called
+ with a filename before using it in a call to stat(2). Bash uses it to
+ expand shell variables so things like $HOME/Downloads have a slash
+ appended.
+
+f. New bindable function `print-last-kbd-macro', prints the most-recently-
+ defined keyboard macro in a reusable format.
+
+g. New user-settable variable `colored-stats', enables use of colored text
+ to denote file types when displaying possible completions (colored analog
+ of visible-stats).
+
+h. New user-settable variable `keyseq-timout', acts as an inter-character
+ timeout when reading input or incremental search strings.
+
+i. New application-callable function: rl_clear_history. Clears the history list
+ and frees all readline-associated private data.
+
+j. New user-settable variable, show-mode-in-prompt, adds a characters to the
+ beginning of the prompt indicating the current editing mode.
+
+k. New application-settable variable: rl_input_available_hook; function to be
+ called when readline needs to check whether there is data available on its
+ input source. The default hook checks rl_instream.
+
+l. Readline calls an application-set event hook (rl_signal_event_hook) after
+ it gets a signal while reading input (read returns -1/EINTR but readline 
+ does not handle the signal immediately) to allow the application to handle
+ or otherwise note it. Not currently called for SIGHUP or SIGTERM.
+ 
+m. If the user-settable variable `history-size' is set to a value less than
+ 0, the history list size is unlimited.
+
+n. When creating shared libraries on Mac OS X, the pathname written into the
+ library (install_name) no longer includes the minor version number.
+
+-------------------------------------------------------------------------------
+This document details the changes between this version, readline-6.2,
+and the previous version, readline-6.1.
+
+1. Changes to Readline
+
+a. Fixed a bug that caused the unconverted filename to be added to the list of
+ completions when the application specified filename conversion functions.
+
+b. Fixed a bug that caused the wrong filename to be passed to opendir when the
+ application has specified a filename dequoting function.
+
+c. Fixed a bug when repeating a character search in vi mode in the case where
+ there was no search to repeat.
+
+d. When show-all-if-ambiguous is set, the completion routines no longer insert
+ a common match prefix that is shorter than the text being completed.
+
+e. The full set of vi editing commands may now be used in callback mode.
+
+f. Fixed a bug that caused readline to not update its idea of the terminal
+ dimensions while running in `no-echo' mode.
+
+h. Fixed a bug that caused readline to dump core if an application called
+ rl_prep_terminal without setting rl_instream.
+
+i. Fixed a bug that caused meta-prefixed characters bound to incremental
+ search forward or backward to not be recognized if they were typed
+ subsequently.
+
+j. The incremental search code treats key sequences that map to the same
+ functions as (default) ^G, ^W, and ^Y as equivalent to those characters.
+
+k. Fixed a bug in menu-complete that caused it to misbehave with large
+ negative argument.
+
+l. Fixed a bug that caused vi-mode yank-last-arg to ring the bell when invoked
+ at the end of the line.
+
+m. Fixed a bug that made an explicit argument of 0 to yank-last-arg behave
+ as if it were a negative argument.
+
+n. Fixed a bug that caused directory names in words to be completed to not
+ be dequoted correctly.
+
+2. New Features in Readline
+
+a. The history library does not try to write the history filename in the
+ current directory if $HOME is unset. This closes a potential security
+ problem if the application does not specify a history filename.
+
+b. New bindable variable `completion-display-width' to set the number of
+ columns used when displaying completions.
+
+c. New bindable variable `completion-case-map' to cause case-insensitive
+ completion to treat `-' and `_' as identical.
+
+d. There are new bindable vi-mode command names to avoid readline's case-
+ insensitive matching not allowing them to be bound separately.
+
+e. New bindable variable `menu-complete-display-prefix' causes the menu
+ completion code to display the common prefix of the possible completions
+ before cycling through the list, instead of after.
+
+-------------------------------------------------------------------------------
+This document details the changes between this version, readline-6.1,
+and the previous version, readline-6.0.
+
+1. Changes to Readline
+
+a. The SIGWINCH signal handler now avoids calling the redisplay code if
+ one arrives while in the middle of redisplay.
+
+b. Changes to the timeout code to make sure that timeout values greater
+ than one second are handled better.
+
+c. Fixed a bug in the redisplay code that was triggered by a prompt
+ containing invisible characters exactly the width of the screen.
+
+d. Fixed a bug in the redisplay code encountered when running in horizontal
+ scroll mode.
+
+e. Fixed a bug that prevented menu completion from properly completing
+ filenames.
+
+f. Fixed a redisplay bug caused by a multibyte character causing a line to
+ wrap.
+
+g. Fixed a bug that caused key sequences of two characters to not be
+ recognized when a longer sequence identical in the first two characters
+ was bound.
+
+h. Fixed a bug that caused history expansion to be attempted on $'...'
+ single-quoted strings.
+
+i. Fixed a bug that caused incorrect redisplay when the prompt contained
+ multibyte characters in an `invisible' sequence bracketed by \ and
+ \.
+
+j. Fixed a bug that caused history expansion to short-circuit after
+ encountering a multibyte character.
+
+k. Fixed a bug that caused applications using the callback interface to not
+ react to SIGINT (or other signals) until another character arrived.
+
+2. New Features in Readline
+
+a. New bindable function: menu-complete-backward.
+
+b. In the vi insertion keymap, C-n is now bound to menu-complete by default,
+ and C-p to menu-complete-backward.
+
+c. When in vi command mode, repeatedly hitting ESC now does nothing, even
+ when ESC introduces a bound key sequence. This is closer to how
+ historical vi behaves.
+
+d. New bindable function: skip-csi-sequence. Can be used as a default to
+ consume key sequences generated by keys like Home and End without having
+ to bind all keys.
+
+e. New application-settable function: rl_filename_rewrite_hook. Can be used
+ to rewite or modify filenames read from the file system before they are
+ compared to the word to be completed.
+
+f. New bindable variable: skip-completed-text, active when completing in the
+ middle of a word. If enabled, it means that characters in the completion
+ that match characters in the remainder of the word are "skipped" rather
+ than inserted into the line.
+
+g. The pre-readline-6.0 version of menu completion is available as
+ "old-menu-complete" for users who do not like the readline-6.0 version.
+
+h. New bindable variable: echo-control-characters. If enabled, and the
+ tty ECHOCTL bit is set, controls the echoing of characters corresponding
+ to keyboard-generated signals.
+
+i. New bindable variable: enable-meta-key. Controls whether or not readline
+ sends the smm/rmm sequences if the terminal indicates it has a meta key
+ that enables eight-bit characters.
+
+-------------------------------------------------------------------------------
+This document details the changes between this version, readline-6.0,
+and the previous version, readline-5.2.
+
+1. Changes to Readline
+
+a. Fixed a number of redisplay errors in environments supporting multibyte 
+ characters.
+
+b. Fixed bugs in vi command mode that caused motion commands to inappropriately
+ set the mark.
+
+c. When using the arrow keys in vi insertion mode, readline allows movement
+ beyond the current end of the line (unlike command mode).
+
+d. Fixed bugs that caused readline to loop when the terminal has been taken
+ away and reads return -1/EIO.
+
+e. Fixed bugs in redisplay occurring when displaying prompts containing
+ invisible characters.
+
+f. Fixed a bug that caused the completion append character to not be reset to
+ the default after an application-specified completion function changed it.
+
+g. Fixed a problem that caused incorrect positioning of the cursor while in
+ emacs editing mode when moving forward at the end of a line while using
+ a locale supporting multibyte characters.
+
+h. Fixed an off-by-one error that caused readline to drop every 511th
+ character of buffered input.
+
+i. Fixed a bug that resulted in SIGTERM not being caught or cleaned up.
+
+j. Fixed redisplay bugs caused by multiline prompts with invisible characters
+ or no characters following the final newline.
+
+k. Fixed redisplay bug caused by prompts consisting solely of invisible
+ characters.
+
+l. Fixed a bug in the code that buffers characters received very quickly in
+ succession which caused characters to be dropped.
+
+m. Fixed a bug that caused readline to reference uninitialized data structures
+ if it received a SIGWINCH before completing initialzation.
+
+n. Fixed a bug that caused the vi-mode `last command' to be set incorrectly
+ and therefore unrepeatable.
+
+o. Fixed a bug that caused readline to disable echoing when it was being used
+ with an output file descriptor that was not a terminal.
+
+p. Readline now blocks SIGINT while manipulating internal data structures
+ during redisplay.
+
+q. Fixed a bug in redisplay that caused readline to segfault when pasting a
+ very long line (over 130,000 characters).
+
+r. Fixed bugs in redisplay when using prompts with no visible printing
+ characters.
+
+s. Fixed a bug that caused redisplay errors when using prompts with invisible
+ characters and numeric arguments to a command in a multibyte locale.
+
+t. Fixed a bug that caused redisplay errors when using prompts with invisible
+ characters spanning more than two physical screen lines.
+
+2. New Features in Readline
+
+a. A new variable, rl_sort_completion_matches; allows applications to inhibit
+ match list sorting (but beware: some things don't work right if
+ applications do this).
+
+b. A new variable, rl_completion_invoking_key; allows applications to discover
+ the key that invoked rl_complete or rl_menu_complete.
+
+c. The functions rl_block_sigint and rl_release_sigint are now public and
+ available to calling applications who want to protect critical sections
+ (like redisplay).
+
+d. The functions rl_save_state and rl_restore_state are now public and
+ available to calling applications; documented rest of readline's state
+ flag values.
+
+e. A new user-settable variable, `history-size', allows setting the maximum
+ number of entries in the history list.
+
+f. There is a new implementation of menu completion, with several improvements
+ over the old; the most notable improvement is a better `completions
+ browsing' mode.
+
+g. The menu completion code now uses the rl_menu_completion_entry_function
+ variable, allowing applications to provide their own menu completion
+ generators.
+
+h. There is support for replacing a prefix of a pathname with a `...' when
+ displaying possible completions. This is controllable by setting the
+ `completion-prefix-display-length' variable. Matches with a common prefix
+ longer than this value have the common prefix replaced with `...'.
+
+i. There is a new `revert-all-at-newline' variable. If enabled, readline will
+ undo all outstanding changes to all history lines when `accept-line' is
+ executed.
+
+-------------------------------------------------------------------------------
+This document details the changes between this version, readline-5.2,
+and the previous version, readline-5.1.
+
+1. Changes to Readline
+
+a. Fixed a problem that caused segmentation faults when using readline in
+ callback mode and typing consecutive DEL characters on an empty line.
+
+b. Fixed several redisplay problems with multibyte characters, all having to
+ do with the different code paths and variable meanings between single-byte
+ and multibyte character redisplay.
+
+c. Fixed a problem with key sequence translation when presented with the
+ sequence \M-\C-x.
+
+d. Fixed a problem that prevented the `a' command in vi mode from being
+ undone and redone properly.
+
+e. Fixed a problem that prevented empty inserts in vi mode from being undone
+ properly.
+
+f. Fixed a problem that caused readline to initialize with an incorrect idea
+ of whether or not the terminal can autowrap.
+
+g. Fixed output of key bindings (like bash `bind -p') to honor the setting of
+ convert-meta and use \e where appropriate.
+
+h. Changed the default filename completion function to call the filename
+ dequoting function if the directory completion hook isn't set. This means
+ that any directory completion hooks need to dequote the directory name,
+ since application-specific hooks need to know how the word was quoted,
+ even if no other changes are made.
+
+i. Fixed a bug with creating the prompt for a non-interactive search string
+ when there are non-printing characters in the primary prompt.
+
+j. Fixed a bug that caused prompts with invisible characters to be redrawn
+ multiple times in a multibyte locale.
+
+k. Fixed a bug that could cause the key sequence scanning code to return the
+ wrong function.
+
+l. Fixed a problem with the callback interface that caused it to fail when
+ using multi-character keyboard macros.
+
+m. Fixed a bug that could cause a core dump when an edited history entry was
+ re-executed under certain conditions.
+
+n. Fixed a bug that caused readline to reference freed memory when attmpting
+ to display a portion of the prompt.
+
+o. Fixed a bug with prompt redisplay in a multi-byte locale to avoid redrawing
+ the prompt and input line multiple times.
+
+p. Fixed history expansion to not be confused by here-string redirection.
+
+q. Readline no longer treats read errors by converting them to newlines, as
+ it does with EOF. This caused partial lines to be returned from readline().
+
+r. Fixed a redisplay bug that occurred in multibyte-capable locales when the
+ prompt was one character longer than the screen width.
+
+2. New Features in Readline
+
+a. Calling applications can now set the keyboard timeout to 0, allowing
+ poll-like behavior.
+
+b. The value of SYS_INPUTRC (configurable at compilation time) is now used as
+ the default last-ditch startup file.
+
+c. The history file reading functions now allow windows-like \r\n line
+ terminators.
+
+-------------------------------------------------------------------------------
+This document details the changes between this version, readline-5.1,
+and the previous version, readline-5.0.
+
+1. Changes to Readline
+
+a. Fixed a bug that caused multiliine prompts to be wrapped and displayed
+ incorrectly.
+
+b. Fixed a bug that caused ^P/^N in emacs mode to fail to display the current
+ line correctly.
+
+c. Fixed a problem in computing the number of invisible characters on the first
+ line of a prompt whose length exceeds the screen width.
+
+d. Fixed vi-mode searching so that failure preserves the current line rather
+ than the last line in the history list.
+
+e. Fixed the vi-mode `~' command (change-case) to have the correct behavior at
+ end-of-line when manipulating multibyte characters.
+
+f. Fixed the vi-mode `r' command (change-char) to have the correct behavior at
+ end-of-line when manipulating multibyte characters.
+
+g. Fixed multiple bugs in the redisplay of multibyte characters: displaying
+ prompts longer than the screen width containing multibyte characters,
+
+h. Fix the calculation of the number of physical characters in the prompt
+ string when it contains multibyte characters.
+
+i. A non-zero value for the `rl_complete_suppress_append' variable now causes
+ no `/' to be appended to a directory name.
+
+j. Fixed forward-word and backward-word to work when words contained
+ multibyte characters.
+
+k. Fixed a bug in finding the delimiter of a `?' substring when performing
+ history expansion in a locale that supports multibyte characters.
+
+l. Fixed a memory leak caused by not freeing the timestamp in a history entry.
+
+m. Fixed a bug that caused "\M-x" style key bindings to not obey the setting
+ of the `convert-meta' variable.
+
+n. Fixed saving and restoring primary prompt when prompting for incremental 
+ and non-incremental searches; search prompts now display multibyte
+ characters correctly.
+
+o. Fixed a bug that caused keys originally bound to self-insert but shadowed
+ by a multi-character key sequence to not be inserted.
+
+p. Fixed code so rl_prep_term_function and rl_deprep_term_function aren't
+ dereferenced if NULL (matching the documentation).
+
+q. Extensive changes to readline to add enough state so that commands
+ requiring additional characters (searches, multi-key sequences, numeric
+ arguments, commands requiring an additional specifier character like
+ vi-mode change-char, etc.) work without synchronously waiting for
+ additional input.
+
+r. Lots of changes so readline builds and runs on MinGW.
+
+s. Readline no longer tries to modify the terminal settings when running in
+ callback mode.
+
+t. The Readline display code no longer sets the location of the last invisible
+ character in the prompt if the \\ sequence is empty.
+
+u. The `change-case' command now correctly changes the case of multibyte
+ characters.
+
+v. Changes to the shared library construction scripts to deal with Windows
+ DLL naming conventions for Cygwin.
+
+w. Fixed the redisplay code to avoid core dumps resulting from a poorly-timed
+ SIGWINCH.
+
+x. Fixed the non-incremental search code in vi mode to dispose of any current
+ undo list when copying a line from the history into the current editing
+ buffer.
+
+y. Fixed a bug that caused reversing the incremental search direction to
+ not work correctly. 
+ 
+z. Fixed the vi-mode `U' command to only undo up to the first time insert mode
+ was entered, as Posix specifies.
+
+aa. Fixed a bug in the vi-mode `r' command that left the cursor in the wrong
+ place.
+
+bb. Fixed a redisplay bug caused by moving the cursor vertically to a line
+ with invisible characters in the prompt in a multibyte locale.
+
+cc. Fixed a bug that could cause the terminal special chars to be bound in the
+ wrong keymap in vi mode.
+
+2. New Features in Readline
+
+a. The key sequence sent by the keypad `delete' key is now automatically 
+ bound to delete-char.
+
+b. A negative argument to menu-complete now cycles backward through the
+ completion list.
+
+c. A new bindable readline variable: bind-tty-special-chars. If non-zero,
+ readline will bind the terminal special characters to their readline
+ equivalents when it's called (on by default).
+
+d. New bindable command: vi-rubout. Saves deleted text for possible 
+ reinsertion, as with any vi-mode `text modification' command; `X' is bound
+ to this in vi command mode.
+
+e. If the rl_completion_query_items is set to a value < 0, readline never
+ asks the user whether or not to view the possible completions.
+
+f. The `C-w' binding in incremental search now understands multibyte
+ characters.
+
+g. New application-callable auxiliary function, rl_variable_value, returns 
+ a string corresponding to a readline variable's value.
+
+h. When parsing inputrc files and variable binding commands, the parser
+ strips trailing whitespace from values assigned to boolean variables
+ before checking them.
+
+i. A new external application-controllable variable that allows the LINES 
+ and COLUMNS environment variables to set the window size regardless of
+ what the kernel returns.
+
+-------------------------------------------------------------------------------
+This document details the changes between this version, readline-5.0,
+and the previous version, readline-4.3.
+
+1. Changes to Readline
+
+a. Fixes to avoid core dumps because of null pointer references in the
+ multibyte character code.
+
+b. Fix to avoid infinite recursion caused by certain key combinations.
+
+c. Fixed a bug that caused the vi-mode `last command' to be set incorrectly.
+
+d. Readline no longer tries to read ahead more than one line of input, even
+ when more is available.
+
+e. Fixed the code that adjusts the point to not mishandle null wide
+ characters.
+
+f. Fixed a bug in the history expansion `g' modifier that caused it to skip
+ every other match.
+
+g. Fixed a bug that caused the prompt to overwrite previous output when the
+ output doesn't contain a newline and the locale supports multibyte
+ characters. This same change fixes the problem of readline redisplay
+ slowing down dramatically as the line gets longer in multibyte locales.
+
+h. History traversal with arrow keys in vi insertion mode causes the cursor
+ to be placed at the end of the new line, like in emacs mode.
+
+i. The locale initialization code does a better job of using the right
+ precedence and defaulting when checking the appropriate environment
+ variables.
+
+j. Fixed the history word tokenizer to handle <( and >( better when used as
+ part of bash.
+
+k. The overwrite mode code received several bug fixes to improve undo.
+
+l. Many speedups to the multibyte character redisplay code.
+
+m. The callback character reading interface should not hang waiting to read
+ keyboard input.
+
+n. Fixed a bug with redoing vi-mode `s' command.
+
+o. The code that initializes the terminal tracks changes made to the terminal
+ special characters with stty(1) (or equivalent), so that these changes
+ are reflected in the readline bindings. New application-callable function
+ to make it work: rl_tty_unset_default_bindings().
+
+p. Fixed a bug that could cause garbage to be inserted in the buffer when
+ changing character case in vi mode when using a multibyte locale.
+
+q. Fixed a bug in the redisplay code that caused problems on systems
+ supporting multibyte characters when moving between history lines when the
+ new line has more glyphs but fewer bytes.
+
+r. Undo and redo now work better after exiting vi insertion mode.
+
+s. Make sure system calls are restarted after a SIGWINCH is received using
+ SA_RESTART.
+
+t. Improvements to the code that displays possible completions when using
+ multibyte characters.
+
+u. Fixed a problem when parsing nested if statements in inputrc files.
+
+v. The completer now takes multibyte characters into account when looking for
+ quoted substrings on which to perform completion.
+
+w. The history search functions now perform better bounds checking on the
+ history list.
+
+x. Change to history expansion functions to treat `^' as equivalent to word 
+ one, as the documention states.
+
+y. Some changes to the display code to improve display and redisplay of
+ multibyte characters.
+
+z. Changes to speed up the multibyte character redisplay code.
+
+aa. Fixed a bug in the vi-mode `E' command that caused it to skip over the
+ last character of a word if invoked while point was on the word's
+ next-to-last character.
+
+bb. Fixed a bug that could cause incorrect filename quoting when
+ case-insensitive completion was enabled and the word being completed
+ contained backslashes quoting word break characters.
+
+cc. Fixed a bug in redisplay triggered when the prompt string contains
+ invisible characters.
+
+dd. Fixed some display (and other) bugs encountered in multibyte locales
+ when a non-ascii character was the last character on a line.
+
+ee. Fixed some display bugs caused by multibyte characters in prompt strings.
+
+ff. Fixed a problem with history expansion caused by non-whitespace characters
+ used as history word delimiters.
+
+gg. Fixed a problem that could cause readline to refer to freed memory when
+ moving between history lines while doing searches.
+
+hh. Improvements to the code that expands and displays prompt strings
+ containing multibyte characters.
+
+ii. Fixed a problem with vi-mode not correctly remembering the numeric argument
+ to the last `c'hange command for later use with `.'.
+
+jj. Fixed a bug in vi-mode that caused multi-digit count arguments to work 
+ incorrectly.
+
+kk. Fixed a problem in vi-mode that caused the last text modification command
+ to not be remembered across different command lines.
+
+ll. Fixed problems with changing characters and changing case at the end of
+ the line.
+
+mm. Fixed a problem with readline saving the contents of the current line
+ before beginning a non-interactive search.
+
+nn. Fixed a problem with EOF detection when using rl_event_hook.
+
+oo. Fixed a problem with the vi mode `p' and `P' commands ignoring numeric
+ arguments.
+
+2. New Features in Readline
+
+a. History expansion has a new `a' modifier equivalent to the `g' modifier
+ for compatibility with the BSD csh.
+
+b. History expansion has a new `G' modifier equivalent to the BSD csh `g'
+ modifier, which performs a substitution once per word.
+
+c. All non-incremental search operations may now undo the operation of
+ replacing the current line with the history line.
+
+d. The text inserted by an `a' command in vi mode can be reinserted with
+ `.'.
+
+e. New bindable variable, `show-all-if-unmodified'. If set, the readline
+ completer will list possible completions immediately if there is more
+ than one completion and partial completion cannot be performed.
+
+f. There is a new application-callable `free_history_entry()' function.
+
+g. History list entries now contain timestamp information; the history file
+ functions know how to read and write timestamp information associated
+ with each entry.
+
+h. Four new key binding functions have been added:
+
+	rl_bind_key_if_unbound()
+	rl_bind_key_if_unbound_in_map()
+	rl_bind_keyseq_if_unbound()
+	rl_bind_keyseq_if_unbound_in_map()
+
+i. New application variable, rl_completion_quote_character, set to any
+ quote character readline finds before it calls the application completion
+ function.
+
+j. New application variable, rl_completion_suppress_quote, settable by an 
+ application completion function. If set to non-zero, readline does not
+ attempt to append a closing quote to a completed word.
+ 
+k. New application variable, rl_completion_found_quote, set to a non-zero
+ value if readline determines that the word to be completed is quoted.
+ Set before readline calls any application completion function.
+
+l. New function hook, rl_completion_word_break_hook, called when readline
+ needs to break a line into words when completion is attempted. Allows
+ the word break characters to vary based on position in the line.
+
+m. New bindable command: unix-filename-rubout. Does the same thing as
+ unix-word-rubout, but adds `/' to the set of word delimiters.
+
+n. When listing completions, directories have a `/' appended if the
+ `mark-directories' option has been enabled.
+
+-------------------------------------------------------------------------------
+This document details the changes between this version, readline-4.3,
+and the previous version, readline-4.2a.
+
+1. Changes to Readline
+
+a. Fixed output of comment-begin character when listing variable values.
+
+b. Added some default key bindings for common escape sequences produced by
+ HOME and END keys.
+
+c. Fixed the mark handling code to be more emacs-compatible.
+
+d. A bug was fixed in the code that prints possible completions to keep it
+ from printing empty strings in certain circumstances.
+
+e. Change the key sequence printing code to print ESC as M\- if ESC is a
+ meta-prefix character -- it's easier for users to understand than \e.
+
+f. Fixed unstifle_history() to return values that match the documentation.
+
+g. Fixed the event loop (rl_event_hook) to handle the case where the input
+ file descriptor is invalidated.
+
+h. Fixed the prompt display code to work better when the application has a
+ custom redisplay function.
+
+i. Changes to make reading and writing the history file a little faster, and
+ to cope with huge history files without calling abort(3) from xmalloc.
+
+j. The vi-mode `S' and `s' commands are now undone correctly.
+
+k. Fixed a problem which caused the display to be messed up when the last
+ line of a multi-line prompt (possibly containing invisible characters)
+ was longer than the screen width.
+
+2. New Features in Readline
+
+a. Support for key `subsequences': allows, e.g., ESC and ESC-a to both
+ be bound to readline functions. Now the arrow keys may be used in vi
+ insert mode.
+
+b. When listing completions, and the number of lines displayed is more than
+ the screen length, readline uses an internal pager to display the results.
+ This is controlled by the `page-completions' variable (default on).
+
+c. New code to handle editing and displaying multibyte characters.
+
+d. The behavior introduced in bash-2.05a of deciding whether or not to
+ append a slash to a completed name that is a symlink to a directory has
+ been made optional, controlled by the `mark-symlinked-directories'
+ variable (default is the 2.05a behavior).
+
+e. The `insert-comment' command now acts as a toggle if given a numeric
+ argument: if the first characters on the line don't specify a
+ comment, insert one; if they do, delete the comment text
+
+f. New application-settable completion variable:
+ rl_completion_mark_symlink_dirs, allows an application's completion
+ function to temporarily override the user's preference for appending
+ slashes to names which are symlinks to directories.
+
+g. New function available to application completion functions:
+ rl_completion_mode, to tell how the completion function was invoked
+ and decide which argument to supply to rl_complete_internal (to list
+ completions, etc.).
+
+h. Readline now has an overwrite mode, toggled by the `overwrite-mode'
+ bindable command, which could be bound to `Insert'.
+
+i. New application-settable completion variable:
+ rl_completion_suppress_append, inhibits appending of
+ rl_completion_append_character to completed words.
+
+j. New key bindings when reading an incremental search string: ^W yanks
+ the currently-matched word out of the current line into the search
+ string; ^Y yanks the rest of the current line into the search string,
+ DEL or ^H deletes characters from the search string.
+
+-------------------------------------------------------------------------------
+This document details the changes between this version, readline-4.2a,
+and the previous version, readline-4.2.
+
+1. Changes to Readline
+
+a. More `const' and type casting fixes.
+
+b. Changed rl_message() to use vsnprintf(3) (if available) to fix buffer
+ overflow problems.
+
+c. The completion code no longer appends a `/' or ` ' to a match when
+ completing a symbolic link that resolves to a directory name, unless
+ the match does not add anything to the word being completed. This
+ means that a tab will complete the word up to the full name, but not
+ add anything, and a subsequent tab will add a slash.
+
+d. Fixed a trivial typo that made the vi-mode `dT' command not work.
+
+e. Fixed the tty code so that ^S and ^Q can be inserted with rl_quoted_insert.
+
+f. Fixed the tty code so that ^V works more than once.
+
+g. Changed the use of __P((...)) for function prototypes to PARAMS((...))
+ because the use of __P in typedefs conflicted g++ and glibc.
+
+h. The completion code now attempts to do a better job of preserving the
+ case of the word the user typed if ignoring case in completions.
+
+i. Readline defaults to not echoing the input and lets the terminal
+ initialization code enable echoing if there is a controlling terminal.
+
+j. The key binding code now processes only two hex digits after a `\x'
+ escape sequence, and the documentation was changed to note that the
+ octal and hex escape sequences result in an eight-bit value rather
+ than strict ASCII.
+
+k. Fixed a few places where negative array subscripts could have occurred.
+ 
+l. Fixed the vi-mode code to use a better method to determine the bounds of
+ the array used to hold the marks, and to avoid out-of-bounds references.
+ 
+m. Fixed the defines in chardefs.h to work better when chars are signed.
+ 
+n. Fixed configure.in to use the new names for bash autoconf macros.
+ 
+o. Readline no longer attempts to define its own versions of some ctype
+ macros if they are implemented as functions in libc but not as macros in
+ <ctype.h>.
+
+p. Fixed a problem where rl_backward could possibly set point to before
+ the beginning of the line.
+
+q. Fixed Makefile to not put -I/usr/include into CFLAGS, since it can cause
+ include file problems.
+
+2. New Features in Readline
+
+a. Added extern declaration for rl_get_termcap to readline.h, making it a
+ public function (it was always there, just not in readline.h).
+
+b. New #defines in readline.h: RL_READLINE_VERSION, currently 0x0402,
+ RL_VERSION_MAJOR, currently 4, and RL_VERSION_MINOR, currently 2.
+
+c. New readline variable: rl_readline_version, mirrors RL_READLINE_VERSION.
+
+d. New bindable boolean readline variable: match-hidden-files. Controls
+ completion of files beginning with a `.' (on Unix). Enabled by default.
+
+e. The history expansion code now allows any character to terminate a
+ `:first-' modifier, like csh.
+
+f. The incremental search code remembers the last search string and uses
+ it if ^R^R is typed without a search string.
+
+h. New bindable variable `history-preserve-point'. If set, the history
+ code attempts to place the user at the same location on each history
+ line retrived with previous-history or next-history.
+
+-------------------------------------------------------------------------------
+This document details the changes between this version, readline-4.2,
+and the previous version, readline-4.1.
+
+1. Changes to Readline
+
+a. When setting the terminal attributes on systems using `struct termio',
+ readline waits for output to drain before changing the attributes.
+
+b. A fix was made to the history word tokenization code to avoid attempts to
+ dereference a null pointer.
+
+c. Readline now defaults rl_terminal_name to $TERM if the calling application
+ has left it unset, and tries to initialize with the resultant value.
+
+d. Instead of calling (*rl_getc_function)() directly to get input in certain
+ places, readline now calls rl_read_key() consistently.
+
+e. Fixed a bug in the completion code that allowed a backslash to quote a
+ single quote inside a single-quoted string.
+
+f. rl_prompt is no longer assigned directly from the argument to readline(),
+ but uses memory allocated by readline. This allows constant strings to
+ be passed to readline without problems arising when the prompt processing
+ code wants to modify the string.
+
+g. Fixed a bug that caused non-interactive history searches to return the
+ wrong line when performing multiple searches backward for the same string.
+
+h. Many variables, function arguments, and function return values are now
+ declared `const' where appropriate, to improve behavior when linking with
+ C++ code.
+
+i. The control character detection code now works better on systems where
+ `char' is unsigned by default.
+
+j. The vi-mode numeric argument is now capped at 999999, just like emacs mode.
+
+k. The Function, CPFunction, CPPFunction, and VFunction typedefs have been
+ replaced with a set of specific prototyped typedefs, though they are
+ still in the readline header files for backwards compatibility.
+
+m. Nearly all of the (undocumented) internal global variables in the library
+ now have an _rl_ prefix -- there were a number that did not, like
+ screenheight, screenwidth, alphabetic, etc.
+
+n. The ding() convenience function has been renamed to rl_ding(), though the
+ old function is still defined for backwards compatibility.
+
+o. The completion convenience functions filename_completion_function,
+ username_completion_function, and completion_matches now have an rl_
+ prefix, though the old names are still defined for backwards compatibility.
+
+p. The functions shared by readline and bash (linkage is satisfied from bash
+ when compiling with bash, and internally otherwise) now have an sh_ prefix.
+
+q. Changed the shared library creation procedure on Linux and BSD/OS 4.x so
+ that the `soname' contains only the major version number rather than the
+ major and minor numbers.
+
+r. Fixed a redisplay bug that occurred when the prompt spanned more than one
+ physical line and contained invisible characters.
+
+s. Added a missing `includedir' variable to the Makefile.
+
+t. When installing the shared libraries, make sure symbolic links are relative.
+
+u. Added configure test so that it can set `${MAKE}' appropriately.
+
+v. Fixed a bug in rl_forward that could cause the point to be set to before
+ the beginning of the line in vi mode.
+
+w. Fixed a bug in the callback read-char interface to make it work when a
+ readline function pushes some input onto the input stream with
+ rl_execute_next (like the incremental search functions).
+
+x. Fixed a file descriptor leak in the history file manipulation code that
+ was tripped when attempting to truncate a non-regular file (like
+ /dev/null).
+
+y. Changes to make all of the exported readline functions declared in
+ readline.h have an rl_ prefix (rltty_set_default_bindings is now
+ rl_tty_set_default_bindings, crlf is now rl_crlf, etc.)
+
+z. The formatted documentation included in the base readline distribution
+ is no longer removed on a `make distclean'.
+
+aa. Some changes were made to avoid gcc warnings with -Wall.
+
+bb. rl_get_keymap_by_name now finds keymaps case-insensitively, so
+ `set keymap EMACS' works.
+
+cc. The history file writing and truncation functions now return a useful
+ status on error.
+
+dd. Fixed a bug that could cause applications to dereference a NULL pointer
+ if a NULL second argument was passed to history_expand().
+
+ee. If a hook function assigned to rl_event_hook sets rl_done to a non-zero
+ value, rl_read_key() now immediately returns '\n' (which is assumed to 
+ be bound to accept-line).
+
+2. New Features in Readline
+
+a. The blink timeout for paren matching is now settable by applications,
+ via the rl_set_paren_blink_timeout() function.
+
+b. _rl_executing_macro has been renamed to rl_executing_macro, which means
+ it's now part of the public interface.
+
+c. Readline has a new variable, rl_readline_state, which is a bitmap that
+ encapsulates the current state of the library; intended for use by
+ callbacks and hook functions.
+
+d. rlfe has a new -l option to log input and output (-a appends to logfile),
+ a new -n option to set the readline application name, and -v and -h
+ options for version and help information.
+
+e. rlfe can now perform filename completion for the inferior process if the
+ OS has a /proc/<PID>/cwd that can be read with readlink(2) to get the
+ inferior's current working directory.
+
+f. A new file, rltypedefs.h, contains the new typedefs for function pointers
+ and is installed by `make install'.
+
+g. New application-callable function rl_set_prompt(const char *prompt):
+ expands its prompt string argument and sets rl_prompt to the result.
+
+h. New application-callable function rl_set_screen_size(int rows, int cols):
+ public method for applications to set readline's idea of the screen
+ dimensions.
+
+i. The history example program (examples/histexamp.c) is now built as one
+ of the examples.
+
+j. The documentation has been updated to cover nearly all of the public
+ functions and variables declared in readline.h.
+
+k. New function, rl_get_screen_size (int *rows, int *columns), returns
+ readline's idea of the screen dimensions.
+
+l. The timeout in rl_gather_tyi (readline keyboard input polling function)
+ is now settable via a function (rl_set_keyboard_input_timeout()).
+
+m. Renamed the max_input_history variable to history_max_entries; the old
+ variable is maintained for backwards compatibility.
+
+n. The list of characters that separate words for the history tokenizer is
+ now settable with a variable: history_word_delimiters. The default
+ value is as before.
+
+o. There is a new history.3 manual page documenting the history library.
+
+-------------------------------------------------------------------------------
+This document details the changes between this version, readline-4.1,
+and the previous version, readline-4.0.
+
+1. Changes to Readline
+
+a. Changed the HTML documents so that the table-of-contents is no longer
+ a separate file.
+
+b. Changes to the shared object configuration for: Irix 5.x, Irix 6.x,
+ OSF/1.
+
+c. The shared library major and minor versions are now constructed
+ automatically by configure and substituted into the makefiles.
+
+d. It's now possible to install the shared libraries separately from the
+ static libraries.
+
+e. The history library tries to truncate the history file only if it is a
+ regular file.
+
+f. A bug that caused _rl_dispatch to address negative array indices on
+ systems with signed chars was fixed.
+
+g. rl-yank-nth-arg now leaves the history position the same as when it was
+ called.
+
+h. Changes to the completion code to handle MS-DOS drive-letter:pathname
+ filenames.
+
+i. Completion is now case-insensitive by default on MS-DOS.
+
+j. Fixes to the history file manipulation code for MS-DOS.
+
+k. Readline attempts to bind the arrow keys to appropriate defaults on MS-DOS.
+
+l. Some fixes were made to the redisplay code for better operation on MS-DOS.
+
+m. The quoted-insert code will now insert tty special chars like ^C.
+
+n. A bug was fixed that caused the display code to reference memory before
+ the start of the prompt string.
+
+o. More support for __EMX__ (OS/2).
+
+p. A bug was fixed in readline's signal handling that could cause infinite
+ recursion in signal handlers.
+
+q. A bug was fixed that caused the point to be less than zero when rl_forward
+ was given a very large numeric argument.
+
+r. The vi-mode code now gets characters via the application-settable value
+ of rl_getc_function rather than calling rl_getc directly.
+
+s. The history file code now uses O_BINARY mode when reading and writing
+ the history file on cygwin32.
+
+t. Fixed a bug in the redisplay code for lines with more than 256 line
+ breaks.
+
+u. A bug was fixed which caused invisible character markers to not be
+ stripped from the prompt string if the terminal was in no-echo mode.
+ 
+v. Readline no longer tries to get the variables it needs for redisplay 
+ from the termcap entry if the calling application has specified its
+ own redisplay function. Readline treats the terminal as `dumb' in
+ this case.
+
+w. Fixes to the SIGWINCH code so that a multiple-line prompt with escape
+ sequences is redrawn correctly.
+
+x. Changes to the install and install-shared targets so that the libraries
+ and header files are installed separately.
+
+2. New Features in Readline
+
+a. A new Readline `user manual' is in doc/rluserman.texinfo.
+
+b. Parentheses matching is now always compiled into readline, and enabled
+ or disabled when the value of the `blink-matching-paren' variable is
+ changed.
+
+c. MS-DOS systems now use ~/_inputrc as the last-ditch inputrc filename.
+
+d. MS-DOS systems now use ~/_history as the default history file.
+
+e. history-search-{forward,backward} now leave the point at the end of the
+ line when the string to search for is empty, like
+ {reverse,forward}-search-history.
+
+f. history-search-{forward,backward} now leave the last history line found
+ in the readline buffer if the second or subsequent search fails.
+
+g. New function for use by applications: rl_on_new_line_with_prompt, used
+ when an application displays the prompt itself before calling readline().
+
+h. New variable for use by applications: rl_already_prompted. An application
+ that displays the prompt itself before calling readline() must set this to
+ a non-zero value.
+
+i. A new variable, rl_gnu_readline_p, always 1. The intent is that an
+ application can verify whether or not it is linked with the `real'
+ readline library or some substitute.
+
+j. Per Bothner's `rlfe' (pronounced `Ralphie') readline front-end program
+ is included in the examples subdirectory, though it is not built
+ by default.
+
+-------------------------------------------------------------------------------
+This document details the changes between this version, readline-4.0,
+and the previous version, readline-2.2.
+
+1. Changes to Readline
+
+a. The version number is now 4.0, to match the major and minor version
+ numbers on the shared readline and history libraries. Future
+ releases will maintain the identical numbering.
+
+b. Fixed a typo in the `make install' recipe that copied libreadline.a
+ to libhistory.old right after installing it.
+
+c. The readline and history info files are now installed out of the source
+ directory if they are not found in the build directory.
+
+d. The library no longer exports a function named `savestring' -- backwards
+ compatibility be damned.
+
+e. There is no longer any #ifdef SHELL code in the source files.
+
+f. Some changes were made to the key binding code to fix memory leaks and
+ better support Win32 systems.
+
+g. Fixed a silly typo in the paren matching code -- it's microseconds, not
+ milliseconds.
+
+h. The readline library should be compilable by C++ compilers.
+
+i. The readline.h public header file now includes function prototypes for
+ all readline functions, and some changes were made to fix errors in the
+ source files uncovered by the use of prototypes.
+
+j. The maximum numeric argument is now clamped at 1000000.
+
+k. Fixes to rl_yank_last_arg to make it behave better.
+
+l. Fixed a bug in the display code that caused core dumps if the prompt
+ string length exceeded 1024 characters.
+
+m. The menu completion code was fixed to properly insert a single completion
+ if there is only one match.
+
+n. A bug was fixed that caused the display code to improperly display tabs
+ after newlines.
+
+o. A fix was made to the completion code in which a typo caused the wrong
+ value to be passed to the function that computed the longest common
+ prefix of the list of matches.
+
+p. The completion code now checks the value of rl_filename_completion_desired,
+ which is set by application-supplied completion functions to indicate
+ that filename completion is being performed, to decide whether or not to
+ call an application-supplied `ignore completions' function.
+
+q. Code was added to the history library to catch history substitutions
+ using `&' without a previous history substitution or search having been
+ performed.
+
+
+2. New Features in Readline
+
+a. There is a new script, support/shobj-conf, to do system-specific shared
+ object and library configuration. It generates variables for configure
+ to substitute into makefiles. The README file provides a detailed
+ explanation of the shared library creation process.
+
+b. Shared libraries and objects are now built in the `shlib' subdirectory.
+ There is a shlib/Makefile.in to control the build process. `make shared'
+ from the top-level directory is still the right way to build shared
+ versions of the libraries.
+
+c. rlconf.h is now installed, so applications can find out which features
+ have been compiled into the installed readline and history libraries.
+
+d. rlstdc.h is now an installed header file.
+
+e. Many changes to the signal handling:
+ o Readline now catches SIGQUIT and cleans up the tty before returning;
+ o A new variable, rl_catch_signals, is available to application writers 
+ to indicate to readline whether or not it should install its own
+ signal handlers for SIGINT, SIGTERM, SIGQUIT, SIGALRM, SIGTSTP,
+ SIGTTIN, and SIGTTOU;
+ o A new variable, rl_catch_sigwinch, is available to application
+ writers to indicate to readline whether or not it should install its
+ own signal handler for SIGWINCH, which will chain to the calling
+ applications's SIGWINCH handler, if one is installed;
+ o There is a new function, rl_free_line_state, for application signal
+ handlers to call to free up the state associated with the current
+ line after receiving a signal;
+ o There is a new function, rl_cleanup_after_signal, to clean up the
+ display and terminal state after receiving a signal;
+ o There is a new function, rl_reset_after_signal, to reinitialize the
+ terminal and display state after an application signal handler
+ returns and readline continues
+
+f. There is a new function, rl_resize_terminal, to reset readline's idea of
+ the screen size after a SIGWINCH.
+
+g. New public functions: rl_save_prompt and rl_restore_prompt. These were
+ previously private functions with a `_' prefix. These functions are
+ used when an application wants to write a message to the `message area'
+ with rl_message and have the prompt restored correctly when the message
+ is erased.
+
+h. New function hook: rl_pre_input_hook, called just before readline starts
+ reading input, after initialization.
+
+i. New function hook: rl_display_matches_hook, called when readline would
+ display the list of completion matches. The new function
+ rl_display_match_list is what readline uses internally, and is available
+ for use by application functions called via this hook.
+
+j. New bindable function, delete-char-or-list, like tcsh.
+
+k. A new variable, rl_erase_empty_line, which, if set by an application using
+ readline, will cause readline to erase, prompt and all, lines on which the
+ only thing typed was a newline.
+
+l. There is a new script, support/shlib-install, to install and uninstall
+ the shared readline and history libraries.
+
+m. A new bindable variable, `isearch-terminators', which is a string
+ containing the set of characters that should terminate an incremental
+ search without being executed as a command.
+
+n. A new bindable function, forward-backward-delete-char.
+
+-------------------------------------------------------------------------------
+This document details the changes between this version, readline-2.2,
+and the previous version, readline-2.1.
+
+1. Changes to Readline
+
+a. Added a missing `extern' to a declaration in readline.h that kept
+ readline from compiling cleanly on some systems.
+
+b. The history file is now opened with mode 0600 when it is written for
+ better security.
+
+c. Changes were made to the SIGWINCH handling code so that prompt redisplay
+ is done better.
+
+d. ^G now interrupts incremental searches correctly.
+
+e. A bug that caused a core dump when the set of characters to be quoted
+ when completing words was empty was fixed.
+
+f. Fixed a problem in the readline test program rltest.c that caused a core
+ dump.
+
+g. The code that handles parser directives in inputrc files now displays
+ more error messages.
+
+h. The history expansion code was fixed so that the appearance of the
+ history comment character at the beginning of a word inhibits history
+ expansion for that word and the rest of the input line.
+
+i. The code that prints completion listings now behaves better if one or
+ more of the filenames contains non-printable characters.
+
+j. The time delay when showing matching parentheses is now 0.5 seconds.
+
+
+2. New Features in Readline
+
+a. There is now an option for `iterative' yank-last-arg handline, so a user
+ can keep entering `M-.', yanking the last argument of successive history
+ lines.
+
+b. New variable, `print-completions-horizontally', which causes completion
+ matches to be displayed across the screen (like `ls -x') rather than up
+ and down the screen (like `ls').
+
+c. New variable, `completion-ignore-case', which causes filename completion
+ and matching to be performed case-insensitively.
+
+d. There is a new bindable command, `magic-space', which causes history
+ expansion to be performed on the current readline buffer and a space to
+ be inserted into the result.
+
+e. There is a new bindable command, `menu-complete', which enables tcsh-like
+ menu completion (successive executions of menu-complete insert a single
+ completion match, cycling through the list of possible completions).
+
+f. There is a new bindable command, `paste-from-clipboard', for use on Win32
+ systems, to insert the text from the Win32 clipboard into the editing
+ buffer.
+
+g. The key sequence translation code now understands printf-style backslash
+ escape sequences, including \NNN octal escapes. These escape sequences
+ may be used in key sequence definitions or macro values.
+
+h. An `$include' inputrc file parser directive has been added.

+
+ Preamble
+
+ The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+ The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works. By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users. We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors. You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+ To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights. Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received. You must make sure that they, too, receive
+or can get the source code. And you must show them these terms so they
+know their rights.
+
+ Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+ For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software. For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+ Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so. This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software. The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable. Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products. If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+ Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary. To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ TERMS AND CONDITIONS
+
+ 0. Definitions.
+
+ "This License" refers to version 3 of the GNU General Public License.
+
+ "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+ "The Program" refers to any copyrightable work licensed under this
+License. Each licensee is addressed as "you". "Licensees" and
+"recipients" may be individuals or organizations.
+
+ To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy. The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+ A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+ To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy. Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+ To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies. Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+ An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License. If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+ 1. Source Code.
+
+ The "source code" for a work means the preferred form of the work
+for making modifications to it. "Object code" means any non-source
+form of a work.
+
+ A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+ The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form. A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+ The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities. However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work. For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+ The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+ The Corresponding Source for a work in source code form is that
+same work.
+
+ 2. Basic Permissions.
+
+ All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met. This License explicitly affirms your unlimited
+permission to run the unmodified Program. The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work. This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+ You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force. You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright. Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+ Conveying under any other circumstances is permitted solely under
+the conditions stated below. Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+ 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+ No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+ When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+ 4. Conveying Verbatim Copies.
+
+ You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+ You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+ 5. Conveying Modified Source Versions.
+
+ You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+ a) The work must carry prominent notices stating that you modified
+ it, and giving a relevant date.
+
+ b) The work must carry prominent notices stating that it is
+ released under this License and any conditions added under section
+ 7. This requirement modifies the requirement in section 4 to
+ "keep intact all notices".
+
+ c) You must license the entire work, as a whole, under this
+ License to anyone who comes into possession of a copy. This
+ License will therefore apply, along with any applicable section 7
+ additional terms, to the whole of the work, and all its parts,
+ regardless of how they are packaged. This License gives no
+ permission to license the work in any other way, but it does not
+ invalidate such permission if you have separately received it.
+
+ d) If the work has interactive user interfaces, each must display
+ Appropriate Legal Notices; however, if the Program has interactive
+ interfaces that do not display Appropriate Legal Notices, your
+ work need not make them do so.
+
+ A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit. Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+ 6. Conveying Non-Source Forms.
+
+ You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+ a) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by the
+ Corresponding Source fixed on a durable physical medium
+ customarily used for software interchange.
+
+ b) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by a
+ written offer, valid for at least three years and valid for as
+ long as you offer spare parts or customer support for that product
+ model, to give anyone who possesses the object code either (1) a
+ copy of the Corresponding Source for all the software in the
+ product that is covered by this License, on a durable physical
+ medium customarily used for software interchange, for a price no
+ more than your reasonable cost of physically performing this
+ conveying of source, or (2) access to copy the
+ Corresponding Source from a network server at no charge.
+
+ c) Convey individual copies of the object code with a copy of the
+ written offer to provide the Corresponding Source. This
+ alternative is allowed only occasionally and noncommercially, and
+ only if you received the object code with such an offer, in accord
+ with subsection 6b.
+
+ d) Convey the object code by offering access from a designated
+ place (gratis or for a charge), and offer equivalent access to the
+ Corresponding Source in the same way through the same place at no
+ further charge. You need not require recipients to copy the
+ Corresponding Source along with the object code. If the place to
+ copy the object code is a network server, the Corresponding Source
+ may be on a different server (operated by you or a third party)
+ that supports equivalent copying facilities, provided you maintain
+ clear directions next to the object code saying where to find the
+ Corresponding Source. Regardless of what server hosts the
+ Corresponding Source, you remain obligated to ensure that it is
+ available for as long as needed to satisfy these requirements.
+
+ e) Convey the object code using peer-to-peer transmission, provided
+ you inform other peers where the object code and Corresponding
+ Source of the work are being offered to the general public at no
+ charge under subsection 6d.
+
+ A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+ A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling. In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage. For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product. A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+ "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source. The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+ If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information. But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+ The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed. Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+ Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+ 7. Additional Terms.
+
+ "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law. If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+ When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it. (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.) You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+ Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+ a) Disclaiming warranty or limiting liability differently from the
+ terms of sections 15 and 16 of this License; or
+
+ b) Requiring preservation of specified reasonable legal notices or
+ author attributions in that material or in the Appropriate Legal
+ Notices displayed by works containing it; or
+
+ c) Prohibiting misrepresentation of the origin of that material, or
+ requiring that modified versions of such material be marked in
+ reasonable ways as different from the original version; or
+
+ d) Limiting the use for publicity purposes of names of licensors or
+ authors of the material; or
+
+ e) Declining to grant rights under trademark law for use of some
+ trade names, trademarks, or service marks; or
+
+ f) Requiring indemnification of licensors and authors of that
+ material by anyone who conveys the material (or modified versions of
+ it) with contractual assumptions of liability to the recipient, for
+ any liability that these contractual assumptions directly impose on
+ those licensors and authors.
+
+ All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10. If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term. If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+ If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+ Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+ 8. Termination.
+
+ You may not propagate or modify a covered work except as expressly
+provided under this License. Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+ However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+ Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License. If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+ 9. Acceptance Not Required for Having Copies.
+
+ You are not required to accept this License in order to receive or
+run a copy of the Program. Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance. However,
+nothing other than this License grants you permission to propagate or
+modify any covered work. These actions infringe copyright if you do
+not accept this License. Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+ 10. Automatic Licensing of Downstream Recipients.
+
+ Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License. You are not responsible
+for enforcing compliance by third parties with this License.
+
+ An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations. If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+ You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License. For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+ 11. Patents.
+
+ A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based. The
+work thus licensed is called the contributor's "contributor version".
+
+ A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version. For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+ Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+ In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement). To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+ If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients. "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+ If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+ A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License. You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+ Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+ 12. No Surrender of Others' Freedom.
+
+ If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all. For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+ 13. Use with the GNU Affero General Public License.
+
+ Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work. The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+ 14. Revised Versions of this License.
+
+ The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation. If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+ If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+ Later license versions may give you additional or different
+permissions. However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+ 15. Disclaimer of Warranty.
+
+ THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. Limitation of Liability.
+
+ IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+ 17. Interpretation of Sections 15 and 16.
+
+ If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software: you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation, either version 3 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program. If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+ If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+ <program> Copyright (C) <year> <name of author>
+ This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+ You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+ The GNU General Public License does not permit incorporating your program
+into proprietary programs. If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library. If this is what you want to do, use the GNU Lesser General
+Public License instead of this License. But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+Basic Installation
+==================
+
+These are installation instructions for Readline-8.1.
+
+The simplest way to compile readline is:
+
+ 1. `cd' to the directory containing the readline source code and type
+ `./configure' to configure readline for your system. If you're
+ using `csh' on an old version of System V, you might need to type
+ `sh ./configure' instead to prevent `csh' from trying to execute
+ `configure' itself.
+
+ Running `configure' takes some time. While running, it prints some
+ messages telling which features it is checking for.
+
+ 2. Type `make' to compile readline and build the static readline
+ and history libraries. If supported, the shared readline and history
+ libraries will be built also. See below for instructions on compiling
+ the other parts of the distribution. Typing `make everything' will
+ cause the static and shared libraries (if supported) and the example
+ programs to be built.
+
+ 3. Type `make install' to install the static readline and history
+ libraries, the readline include files, the documentation, and, if
+ supported, the shared readline and history libraries.
+
+ 4. You can remove the created libraries and object files from the
+ build directory by typing `make clean'. To also remove the
+ files that `configure' created (so you can compile readline for
+ a different kind of computer), type `make distclean'. There is
+ also a `make maintainer-clean' target, but that is intended mainly
+ for the readline developers, and should be used with care.
+
+The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It
+uses those values to create a `Makefile' in the build directory,
+and Makefiles in the `doc', `shlib', and `examples'
+subdirectories. It also creates a `config.h' file containing
+system-dependent definitions. Finally, it creates a shell script
+`config.status' that you can run in the future to recreate the
+current configuration, a file `config.cache' that saves the
+results of its tests to speed up reconfiguring, and a file
+`config.log' containing compiler output (useful mainly for
+debugging `configure'). 
+
+If you need to do unusual things to compile readline, please try
+to figure out how `configure' could check whether to do them, and
+mail diffs or instructions to <bug-readline@gnu.org> so they can
+be considered for the next release. If at some point
+`config.cache' contains results you don't want to keep, you may
+remove or edit it. 
+
+The file `configure.in' is used to create `configure' by a
+program called `autoconf'. You only need `configure.in' if you
+want to change it or regenerate `configure' using a newer version
+of `autoconf'. The readline `configure.in' requires autoconf
+version 2.50 or newer. 
+
+Compilers and Options
+=====================
+
+Some systems require unusual options for compilation or linking that
+the `configure' script does not know about. You can give `configure'
+initial values for variables by setting them in the environment. Using
+a Bourne-compatible shell, you can do that on the command line like
+this:
+
+ CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
+
+Or on systems that have the `env' program, you can do it like this:
+
+ env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+
+Compiling For Multiple Architectures
+====================================
+
+You can compile readline for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory. To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'. `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script. `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+If you have to use a `make' that does not supports the `VPATH'
+variable, you have to compile readline for one architecture at a
+time in the source code directory. After you have installed
+readline for one architecture, use `make distclean' before
+reconfiguring for another architecture. 
+
+Installation Names
+==================
+
+By default, `make install' will install the readline libraries in
+`/usr/local/lib', the include files in
+`/usr/local/include/readline', the man pages in `/usr/local/man',
+and the info files in `/usr/local/info'. You can specify an
+installation prefix other than `/usr/local' by giving `configure'
+the option `--prefix=PATH' or by supplying a value for the
+DESTDIR variable when running `make install'. 
+
+You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. 
+If you give `configure' the option `--exec-prefix=PATH', the
+readline Makefiles will use PATH as the prefix for installing the
+libraries. Documentation and other data files will still use the
+regular prefix. 
+
+Specifying the System Type
+==========================
+
+There may be some features `configure' can not figure out
+automatically, but need to determine by the type of host readline
+will run on. Usually `configure' can figure that out, but if it
+prints a message saying it can not guess the host type, give it
+the `--host=TYPE' option. TYPE can either be a short name for
+the system type, such as `sun4', or a canonical name with three
+fields: CPU-COMPANY-SYSTEM (e.g., i386-unknown-freebsd4.2). 
+
+See the file `config.sub' for the possible values of each field.
+
+Sharing Defaults
+================
+
+If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists. Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: the readline `configure' looks for a site script, but not
+all `configure' scripts do.
+
+Operation Controls
+==================
+
+`configure' recognizes the following options to control how it
+operates.
+
+`--cache-file=FILE'
+ Use and save the results of the tests in FILE instead of
+ `./config.cache'. Set FILE to `/dev/null' to disable caching, for
+ debugging `configure'.
+
+`--help'
+ Print a summary of the options to `configure', and exit.
+
+`--quiet'
+`--silent'
+`-q'
+ Do not print messages saying which checks are being made.
+
+`--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+`--version'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+`configure' also accepts some other, not widely useful, options.
+
+Optional Features
+=================
+
+The readline `configure' recognizes a single `--with-PACKAGE' option:
+
+`--with-curses'
+ This tells readline that it can find the termcap library functions
+ (tgetent, et al.) in the curses library, rather than a separate
+ termcap library. Readline uses the termcap functions, but does not
+ link with the termcap or curses library itself, allowing applications
+ which link with readline the to choose an appropriate library.
+ This option tells readline to link the example programs with the
+ curses library rather than libtermcap.
+
+`configure' also recognizes two `--enable-FEATURE' options:
+
+`--enable-shared'
+ Build the shared libraries by default on supported platforms. The
+ default is `yes'.
+
+`--enable-static'
+ Build the static libraries by default. The default is `yes'.
+
+`--enable-bracketed-paste-default'
+ Enable bracketed paste by default, so the initial value of the
+ `enable-bracketed-paste' Readline variable is `on'. The default
+ is `yes'.
+ 
+Shared Libraries
+================
+
+There is support for building shared versions of the readline and
+history libraries. The configure script creates a Makefile in
+the `shlib' subdirectory, and typing `make shared' will cause
+shared versions of the readline and history libraries to be built
+on supported platforms.
+
+If `configure' is given the `--enable-shared' option, it will attempt
+to build the shared libraries by default on supported platforms.
+
+Configure calls the script support/shobj-conf to test whether or
+not shared library creation is supported and to generate the values
+of variables that are substituted into shlib/Makefile. If you
+try to build shared libraries on an unsupported platform, `make'
+will display a message asking you to update support/shobj-conf for
+your platform.
+
+If you need to update support/shobj-conf, you will need to create
+a `stanza' for your operating system and compiler. The script uses
+the value of host_os and ${CC} as determined by configure. For
+instance, FreeBSD 4.2 with any version of gcc is identified as
+`freebsd4.2-gcc*'.
+
+In the stanza for your operating system-compiler pair, you will need to
+define several variables. They are:
+
+SHOBJ_CC	The C compiler used to compile source files into shareable
+		object files. This is normally set to the value of ${CC}
+		by configure, and should not need to be changed.
+
+SHOBJ_CFLAGS	Flags to pass to the C compiler ($SHOBJ_CC) to create
+		position-independent code. If you are using gcc, this
+		should probably be set to `-fpic'.
+
+SHOBJ_LD	The link editor to be used to create the shared library from
+		the object files created by $SHOBJ_CC. If you are using
+		gcc, a value of `gcc' will probably work.
+
+SHOBJ_LDFLAGS	Flags to pass to SHOBJ_LD to enable shared object creation.
+		If you are using gcc, `-shared' may be all that is necessary.
+		These should be the flags needed for generic shared object
+		creation.
+
+SHLIB_XLDFLAGS	Additional flags to pass to SHOBJ_LD for shared library
+		creation. Many systems use the -R option to the link
+		editor to embed a path within the library for run-time
+		library searches. A reasonable value for such systems would
+		be `-R$(libdir)'.
+
+SHLIB_LIBS	Any additional libraries that shared libraries should be
+		linked against when they are created.
+
+SHLIB_LIBPREF	The prefix to use when generating the filename of the shared
+		library. The default is `lib'; Cygwin uses `cyg'.
+
+SHLIB_LIBSUFF	The suffix to add to `libreadline' and `libhistory' when
+		generating the filename of the shared library. Many systems
+		use `so'; HP-UX uses `sl'.
+
+SHLIB_LIBVERSION The string to append to the filename to indicate the version
+		of the shared library. It should begin with $(SHLIB_LIBSUFF),
+		and possibly include version information that allows the
+		run-time loader to load the version of the shared library
+		appropriate for a particular program. Systems using shared
+		libraries similar to SunOS 4.x use major and minor library
+		version numbers; for those systems a value of
+		`$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)$(SHLIB_MINOR)' is appropriate.
+		Systems based on System V Release 4 don't use minor version
+		numbers; use `$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)' on those systems.
+		Other Unix versions use different schemes.
+
+SHLIB_DLLVERSION The version number for shared libraries that determines API
+		compatibility between readline versions and the underlying
+		system. Used only on Cygwin. Defaults to $SHLIB_MAJOR, but
+		can be overridden at configuration time by defining DLLVERSION
+		in the environment.
+
+SHLIB_DOT	The character used to separate the name of the shared library
+		from the suffix and version information. The default is `.';
+		systems like Cygwin which don't separate version information
+		from the library name should set this to the empty string.
+
+SHLIB_STATUS	Set this to `supported' when you have defined the other
+		necessary variables. Make uses this to determine whether
+		or not shared library creation should be attempted. If
+		shared libraries are not supported, this will be set to
+		`unsupported'.
+
+You should look at the existing stanzas in support/shobj-conf for ideas.
+
+Once you have updated support/shobj-conf, re-run configure and type
+`make shared' or `make'. The shared libraries will be created in the
+shlib subdirectory.
+
+If shared libraries are created, `make install' will install them. 
+You may install only the shared libraries by running `make
+install-shared' from the top-level build directory. Running `make
+install' in the shlib subdirectory will also work. If you don't want
+to install any created shared libraries, run `make install-static'.

+This is a terse description of the new features added to readline-8.1 since
+the release of readline-8.0.
+
+New Features in Readline
+
+a. If a second consecutive completion attempt produces matches where the first
+ did not, treat it as a new completion attempt and insert a match as
+ appropriate.
+
+b. Bracketed paste mode works in more places: incremental search strings, vi
+ overstrike mode, character search, and reading numeric arguments.
+
+c. Readline automatically switches to horizontal scrolling if the terminal has
+ only one line.
+
+d. Unbinding all key sequences bound to a particular readline function now
+ descends into keymaps for multi-key sequences.
+
+e. rl-clear-display: new bindable command that clears the screen and, if
+ possible, the scrollback buffer (bound to emacs mode M-C-l by default).
+
+f. New active mark and face feature: when enabled, it will highlight the text
+ inserted by a bracketed paste (the `active region') and the text found by
+ incremental and non-incremental history searches. This is tied to bracketed
+ paste and can be disabled by turning off bracketed paste.
+
+g. Readline sets the mark in several additional commands.
+
+h. Bracketed paste mode is enabled by default. There is a configure-time
+ option (--enable-bracketed-paste-default) to set the default to on or off.
+
+i. Readline tries to take advantage of the more regular structure of UTF-8
+ characters to identify the beginning and end of characters when moving
+ through the line buffer.
+
+j. The bindable operate-and-get-next command (and its default bindings) are
+ now part of readline instead of a bash-specific addition.
+
+k. The signal cleanup code now blocks SIGINT while processing after a SIGINT. 
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to readline-8.0 since
+the release of readline-7.0.
+
+New Features in Readline
+
+a. Non-incremental vi-mode search (`N', `n') can search for a shell pattern, as
+ Posix specifies (uses fnmatch(3) if available).
+
+b. There are new `next-screen-line' and `previous-screen-line' bindable
+ commands, which move the cursor to the same column in the next, or previous,
+ physical line, respectively.
+
+c. There are default key bindings for control-arrow-key key combinations.
+
+d. A negative argument (-N) to `quoted-insert' means to insert the next N
+ characters using quoted-insert.
+
+e. New public function: rl_check_signals(), which allows applications to
+ respond to signals that readline catches while waiting for input using
+ a custom read function.
+
+f. There is new support for conditionally testing the readline version in an
+ inputrc file, with a full set of arithmetic comparison operators available.
+
+g. There is a simple variable comparison facility available for use within an
+ inputrc file. Allowable operators are equality and inequality; string
+ variables may be compared to a value; boolean variables must be compared to
+ either `on' or `off'; variable names are separated from the operator by
+ whitespace.
+
+h. The history expansion library now understands command and process
+ substitution and extended globbing and allows them to appear anywhere in a
+ word.
+
+i. The history library has a new variable that allows applications to set the
+ initial quoting state, so quoting state can be inherited from a previous
+ line.
+
+j. Readline now allows application-defined keymap names; there is a new public
+ function, rl_set_keymap_name(), to do that.
+
+k. The "Insert" keypad key, if available, now puts readline into overwrite
+ mode.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to readline-7.0 since
+the release of readline-6.3.
+
+New Features in Readline
+
+a. The history truncation code now uses the same error recovery mechansim as
+ the history writing code, and restores the old version of the history file
+ on error. The error recovery mechanism handles symlinked history files.
+
+b. There is a new bindable variable, `enable-bracketed-paste', which enables
+ support for a terminal's bracketed paste mode.
+
+c. The editing mode indicators can now be strings and are user-settable
+ (new `emacs-mode-string', `vi-cmd-mode-string' and `vi-ins-mode-string'
+ variables). Mode strings can contain invisible character sequences.
+ Setting mode strings to null strings restores the defaults.
+
+d. Prompt expansion adds the mode string to the last line of a multi-line
+ prompt (one with embedded newlines).
+
+e. There is a new bindable variable, `colored-completion-prefix', which, if
+ set, causes the common prefix of a set of possible completions to be
+ displayed in color.
+
+f. There is a new bindable command `vi-yank-pop', a vi-mode version of emacs-
+ mode yank-pop.
+
+g. The redisplay code underwent several efficiency improvements for multibyte
+ locales.
+
+h. The insert-char function attempts to batch-insert all pending typeahead
+ that maps to self-insert, as long as it is coming from the terminal.
+
+i. rl_callback_sigcleanup: a new application function that can clean up and
+ unset any state set by readline's callback mode. Intended to be used
+ after a signal.
+
+j. If an incremental search string has its last character removed with DEL, the
+ resulting empty search string no longer matches the previous line.
+
+k. If readline reads a history file that begins with `#' (or the value of
+ the history comment character) and has enabled history timestamps, the history
+ entries are assumed to be delimited by timestamps. This allows multi-line
+ history entries.
+
+l. Readline now throws an error if it parses a key binding without a terminating
+ `:' or whitespace.
+
+m. The default binding for ^W in vi mode now uses word boundaries specified
+ by Posix (vi-unix-word-rubout is bindable command name).
+
+n. rl_clear_visible_line: new application-callable function; clears all
+ screen lines occupied by the current visible readline line.
+
+o. rl_tty_set_echoing: application-callable function that controls whether
+ or not readline thinks it is echoing terminal output.
+
+p. Handle >| and strings of digits preceding and following redirection
+ specifications as single tokens when tokenizing the line for history
+ expansion.
+
+q. Fixed a bug with displaying completions when the prefix display length
+ is greater than the length of the completions to be displayed.
+
+r. The :p history modifier now applies to the entire line, so any expansion
+ specifying :p causes the line to be printed instead of expanded.
+
+s. New application-callable function: rl_pending_signal(): returns the signal
+ number of any signal readline has caught but not yet handled.
+ 
+t. New application-settable variable: rl_persistent_signal_handlers: if set
+ to a non-zero value, readline will enable the readline-6.2 signal handler
+ behavior in callback mode: handlers are installed when
+ rl_callback_handler_install is called and removed removed when a complete
+ line has been read.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to readline-6.3 since
+the release of readline-6.2.
+
+New Features in Readline
+
+a. Readline is now more responsive to SIGHUP and other fatal signals when
+ reading input from the terminal or performing word completion but no
+ longer attempts to run any not-allowable functions from a signal handler
+ context.
+
+b. There are new bindable commands to search the history for the string of
+ characters between the beginning of the line and the point
+ (history-substring-search-forward, history-substring-search-backward)
+
+c. Readline allows quoted strings as the values of variables when setting
+ them with `set'. As a side effect, trailing spaces and tabs are ignored
+ when setting a string variable's value.
+
+d. The history library creates a backup of the history file when writing it
+ and restores the backup on a write error.
+
+e. New application-settable variable: rl_filename_stat_hook: a function called
+ with a filename before using it in a call to stat(2). Bash uses it to
+ expand shell variables so things like $HOME/Downloads have a slash
+ appended.
+
+f. New bindable function `print-last-kbd-macro', prints the most-recently-
+ defined keyboard macro in a reusable format.
+
+g. New user-settable variable `colored-stats', enables use of colored text
+ to denote file types when displaying possible completions (colored analog
+ of visible-stats).
+
+h. New user-settable variable `keyseq-timout', acts as an inter-character
+ timeout when reading input or incremental search strings.
+
+i. New application-callable function: rl_clear_history. Clears the history list
+ and frees all readline-associated private data.
+
+j. New user-settable variable, show-mode-in-prompt, adds a characters to the
+ beginning of the prompt indicating the current editing mode.
+
+k. New application-settable variable: rl_input_available_hook; function to be
+ called when readline detects there is data available on its input file
+ descriptor.
+
+l. Readline calls an application-set event hook (rl_event_hook) after it gets
+ a signal while reading input (read returns -1/EINTR but readline does not
+ handle the signal immediately) to allow the application to handle or
+ otherwise note it.
+
+m. If the user-settable variable `history-size' is set to a value less than
+ 0, the history list size is unlimited.
+
+n. New application-settable variable: rl_signal_event_hook; function that is
+ called when readline is reading terminal input and read(2) is interrupted
+ by a signal. Currently not called for SIGHUP or SIGTERM.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to readline-6.2 since
+the release of readline-6.1.
+
+a. The history library does not try to write the history filename in the
+ current directory if $HOME is unset. This closes a potential security
+ problem if the application does not specify a history filename.
+
+b. New bindable variable `completion-display-width' to set the number of
+ columns used when displaying completions.
+
+c. New bindable variable `completion-case-map' to cause case-insensitive
+ completion to treat `-' and `_' as identical.
+
+d. There are new bindable vi-mode command names to avoid readline's case-
+ insensitive matching not allowing them to be bound separately.
+
+e. New bindable variable `menu-complete-display-prefix' causes the menu
+ completion code to display the common prefix of the possible completions
+ before cycling through the list, instead of after.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to readline-6.1 since
+the release of readline-6.0.
+
+New Features in Readline
+
+a. New bindable function: menu-complete-backward.
+
+b. In the vi insertion keymap, C-n is now bound to menu-complete by default,
+ and C-p to menu-complete-backward.
+
+c. When in vi command mode, repeatedly hitting ESC now does nothing, even
+ when ESC introduces a bound key sequence. This is closer to how
+ historical vi behaves.
+
+d. New bindable function: skip-csi-sequence. Can be used as a default to
+ consume key sequences generated by keys like Home and End without having
+ to bind all keys.
+
+e. New application-settable function: rl_filename_rewrite_hook. Can be used
+ to rewite or modify filenames read from the file system before they are
+ compared to the word to be completed.
+
+f. New bindable variable: skip-completed-text, active when completing in the
+ middle of a word. If enabled, it means that characters in the completion
+ that match characters in the remainder of the word are "skipped" rather
+ than inserted into the line.
+
+g. The pre-readline-6.0 version of menu completion is available as
+ "old-menu-complete" for users who do not like the readline-6.0 version.
+
+h. New bindable variable: echo-control-characters. If enabled, and the
+ tty ECHOCTL bit is set, controls the echoing of characters corresponding
+ to keyboard-generated signals.
+
+i. New bindable variable: enable-meta-key. Controls whether or not readline
+ sends the smm/rmm sequences if the terminal indicates it has a meta key
+ that enables eight-bit characters.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to readline-6.0 since
+the release of readline-5.2.
+
+New Features in Readline
+
+a. A new variable, rl_sort_completion_matches; allows applications to inhibit
+ match list sorting (but beware: some things don't work right if
+ applications do this).
+
+b. A new variable, rl_completion_invoking_key; allows applications to discover
+ the key that invoked rl_complete or rl_menu_complete.
+
+c. The functions rl_block_sigint and rl_release_sigint are now public and
+ available to calling applications who want to protect critical sections
+ (like redisplay).
+
+d. The functions rl_save_state and rl_restore_state are now public and
+ available to calling applications; documented rest of readline's state
+ flag values.
+
+e. A new user-settable variable, `history-size', allows setting the maximum
+ number of entries in the history list.
+
+f. There is a new implementation of menu completion, with several improvements
+ over the old; the most notable improvement is a better `completions
+ browsing' mode.
+
+g. The menu completion code now uses the rl_menu_completion_entry_function
+ variable, allowing applications to provide their own menu completion
+ generators.
+
+h. There is support for replacing a prefix of a pathname with a `...' when
+ displaying possible completions. This is controllable by setting the
+ `completion-prefix-display-length' variable. Matches with a common prefix
+ longer than this value have the common prefix replaced with `...'.
+
+i. There is a new `revert-all-at-newline' variable. If enabled, readline will
+ undo all outstanding changes to all history lines when `accept-line' is
+ executed.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to readline-5.2 since
+the release of readline-5.1.
+
+New Features in Readline
+
+a. Calling applications can now set the keyboard timeout to 0, allowing
+ poll-like behavior.
+
+b. The value of SYS_INPUTRC (configurable at compilation time) is now used as
+ the default last-ditch startup file.
+
+c. The history file reading functions now allow windows-like \r\n line
+ terminators.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to readline-5.1 since
+the release of readline-5.0.
+
+New Features in Readline
+
+a. The key sequence sent by the keypad `delete' key is now automatically 
+ bound to delete-char.
+
+b. A negative argument to menu-complete now cycles backward through the
+ completion list.
+
+c. A new bindable readline variable: bind-tty-special-chars. If non-zero,
+ readline will bind the terminal special characters to their readline
+ equivalents when it's called (on by default).
+
+d. New bindable command: vi-rubout. Saves deleted text for possible 
+ reinsertion, as with any vi-mode `text modification' command; `X' is bound
+ to this in vi command mode.
+
+e. If the rl_completion_query_items is set to a value < 0, readline never
+ asks the user whether or not to view the possible completions.
+
+f. New application-callable auxiliary function, rl_variable_value, returns
+ a string corresponding to a readline variable's value.
+
+g. When parsing inputrc files and variable binding commands, the parser
+ strips trailing whitespace from values assigned to boolean variables
+ before checking them.
+
+h. A new external application-controllable variable that allows the LINES
+ and COLUMNS environment variables to set the window size regardless of
+ what the kernel returns.
+
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to readline-5.0 since
+the release of readline-4.3.
+
+New Features in Readline
+
+a. History expansion has a new `a' modifier equivalent to the `g' modifier
+ for compatibility with the BSD csh.
+
+b. History expansion has a new `G' modifier equivalent to the BSD csh `g'
+ modifier, which performs a substitution once per word.
+
+c. All non-incremental search operations may now undo the operation of
+ replacing the current line with the history line.
+
+d. The text inserted by an `a' command in vi mode can be reinserted with
+ `.'.
+
+e. New bindable variable, `show-all-if-unmodified'. If set, the readline
+ completer will list possible completions immediately if there is more
+ than one completion and partial completion cannot be performed.
+
+f. There is a new application-callable `free_history_entry()' function.
+
+g. History list entries now contain timestamp information; the history file
+ functions know how to read and write timestamp information associated
+ with each entry.
+
+h. Four new key binding functions have been added:
+
+	rl_bind_key_if_unbound()
+	rl_bind_key_if_unbound_in_map()
+	rl_bind_keyseq_if_unbound()
+	rl_bind_keyseq_if_unbound_in_map()
+
+i. New application variable, rl_completion_quote_character, set to any
+ quote character readline finds before it calls the application completion
+ function.
+
+j. New application variable, rl_completion_suppress_quote, settable by an 
+ application completion function. If set to non-zero, readline does not
+ attempt to append a closing quote to a completed word.
+ 
+k. New application variable, rl_completion_found_quote, set to a non-zero
+ value if readline determines that the word to be completed is quoted.
+ Set before readline calls any application completion function.
+
+l. New function hook, rl_completion_word_break_hook, called when readline
+ needs to break a line into words when completion is attempted. Allows
+ the word break characters to vary based on position in the line.
+
+m. New bindable command: unix-filename-rubout. Does the same thing as
+ unix-word-rubout, but adds `/' to the set of word delimiters.
+
+n. When listing completions, directories have a `/' appended if the
+ `mark-directories' option has been enabled.

+Introduction
+============
+
+This is the Gnu Readline library, version 8.1.
+
+The Readline library provides a set of functions for use by applications
+that allow users to edit command lines as they are typed in.  Both
+Emacs and vi editing modes are available.  The Readline library includes
+additional functions to maintain a list of previously-entered command
+lines, to recall and perhaps reedit those lines, and perform csh-like
+history expansion on previous commands.
+
+The history facilites are also placed into a separate library, the
+History library, as part of the build process.  The History library
+may be used without Readline in applications which desire its
+capabilities.
+
+The Readline library is free software, distributed under the terms of
+the GNU General Public License as published by the Free Software
+Foundation, version 3 of the License.  For more information, see the
+file COPYING.
+
+To build the library, try typing `./configure', then `make'.  The
+configuration process is automated, so no further intervention should
+be necessary.  Readline builds with `gcc' by default if it is
+available.  If you want to use `cc' instead, type
+
+        CC=cc ./configure
+
+if you are using a Bourne-style shell.  If you are not, the following
+may work:
+
+        env CC=cc ./configure
+
+Read the file INSTALL in this directory for more information about how
+to customize and control the build process.
+
+The file rlconf.h contains C preprocessor defines that enable and disable
+certain Readline features.
+
+The special make target `everything' will build the static and shared
+libraries (if the target platform supports them) and the examples.
+
+Examples
+========
+
+There are several example programs that use Readline features in the
+examples directory.  The `rl' program is of particular interest.  It
+is a command-line interface to Readline, suitable for use in shell
+scripts in place of `read'.
+
+Shared Libraries
+================
+
+There is skeletal support for building shared versions of the
+Readline and History libraries.  The configure script creates
+a Makefile in the `shlib' subdirectory, and typing `make shared'
+will cause shared versions of the Readline and History libraries
+to be built on supported platforms.
+
+If `configure' is given the `--enable-shared' option, it will attempt
+to build the shared libraries by default on supported platforms.
+
+Configure calls the script support/shobj-conf to test whether or
+not shared library creation is supported and to generate the values
+of variables that are substituted into shlib/Makefile.  If you
+try to build shared libraries on an unsupported platform, `make'
+will display a message asking you to update support/shobj-conf for
+your platform.
+
+If you need to update support/shobj-conf, you will need to create
+a `stanza' for your operating system and compiler.  The script uses
+the value of host_os and ${CC} as determined by configure.  For
+instance, FreeBSD 4.2 with any version of gcc is identified as
+`freebsd4.2-gcc*'.
+
+In the stanza for your operating system-compiler pair, you will need to
+define several variables.  They are:
+
+SHOBJ_CC	The C compiler used to compile source files into shareable
+		object files.  This is normally set to the value of ${CC}
+		by configure, and should not need to be changed.
+
+SHOBJ_CFLAGS	Flags to pass to the C compiler ($SHOBJ_CC) to create
+		position-independent code.  If you are using gcc, this
+		should probably be set to `-fpic'.
+
+SHOBJ_LD	The link editor to be used to create the shared library from
+		the object files created by $SHOBJ_CC.  If you are using
+		gcc, a value of `gcc' will probably work.
+
+SHOBJ_LDFLAGS	Flags to pass to SHOBJ_LD to enable shared object creation.
+		If you are using gcc, `-shared' may be all that is necessary.
+		These should be the flags needed for generic shared object
+		creation.
+
+SHLIB_XLDFLAGS	Additional flags to pass to SHOBJ_LD for shared library
+		creation.  Many systems use the -R option to the link
+		editor to embed a path within the library for run-time
+		library searches.  A reasonable value for such systems would
+		be `-R$(libdir)'.
+
+SHLIB_LIBS	Any additional libraries that shared libraries should be
+		linked against when they are created.
+
+SHLIB_LIBPREF	The prefix to use when generating the filename of the shared
+		library.  The default is `lib'; Cygwin uses `cyg'.
+
+SHLIB_LIBSUFF	The suffix to add to `libreadline' and `libhistory' when
+		generating the filename of the shared library.  Many systems
+		use `so'; HP-UX uses `sl'.
+
+SHLIB_LIBVERSION The string to append to the filename to indicate the version
+		of the shared library.  It should begin with $(SHLIB_LIBSUFF),
+		and possibly include version information that allows the
+		run-time loader to load the version of the shared library
+		appropriate for a particular program.  Systems using shared
+		libraries similar to SunOS 4.x use major and minor library
+		version numbers; for those systems a value of
+		`$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)$(SHLIB_MINOR)' is appropriate.
+		Systems based on System V Release 4 don't use minor version
+		numbers; use `$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)' on those systems.
+		Other Unix versions use different schemes.
+
+SHLIB_DLLVERSION The version number for shared libraries that determines API
+		compatibility between readline versions and the underlying
+		system.  Used only on Cygwin.  Defaults to $SHLIB_MAJOR, but
+		can be overridden at configuration time by defining DLLVERSION
+		in the environment.
+
+SHLIB_DOT	The character used to separate the name of the shared library
+		from the suffix and version information.  The default is `.';
+		systems like Cygwin which don't separate version information
+		from the library name should set this to the empty string.
+
+SHLIB_STATUS	Set this to `supported' when you have defined the other
+		necessary variables.  Make uses this to determine whether
+		or not shared library creation should be attempted.
+
+You should look at the existing stanzas in support/shobj-conf for ideas.
+
+Once you have updated support/shobj-conf, re-run configure and type
+`make shared'.  The shared libraries will be created in the shlib
+subdirectory.
+
+If shared libraries are created, `make install' will install them. 
+You may install only the shared libraries by running `make
+install-shared' from the top-level build directory.  Running `make
+install' in the shlib subdirectory will also work.  If you don't want
+to install any created shared libraries, run `make install-static'. 
+
+Documentation
+=============
+
+The documentation for the Readline and History libraries appears in
+the `doc' subdirectory.  There are three texinfo files and a
+Unix-style manual page describing the facilities available in the
+Readline library.  The texinfo files include both user and
+programmer's manuals.  HTML versions of the manuals appear in the
+`doc' subdirectory as well. 
+
+Usage
+=====
+
+Our position on the use of Readline through a shared-library linking
+mechanism is that there is no legal difference between shared-library
+linking and static linking--either kind of linking combines various
+modules into a single larger work.  The conditions for using Readline
+in a larger work are stated in section 3 of the GNU GPL.
+
+Reporting Bugs
+==============
+
+Bug reports for Readline should be sent to:
+
+        bug-readline@gnu.org
+
+When reporting a bug, please include the following information:
+
+        * the version number and release status of Readline (e.g., 4.2-release)
+        * the machine and OS that it is running on
+        * a list of the compilation flags or the contents of `config.h', if
+          appropriate
+        * a description of the bug
+        * a recipe for recreating the bug reliably
+        * a fix for the bug if you have one!
+
+If you would like to contact the Readline maintainer directly, send mail
+to bash-maintainers@gnu.org.
+
+Since Readline is developed along with bash, the bug-bash@gnu.org mailing
+list (mirrored to the Usenet newsgroup gnu.bash.bug) often contains
+Readline bug reports and fixes.

+\`configure' configures readline 8.1 to adapt to many kinds of systems.
+
+Usage: $0 OPTION... VAR=VALUE...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE disabled
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR configure dir or \`..'
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ $ac_default_prefix
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ PREFIX
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables EPREFIX/bin
+ --sbindir=DIR system admin executables EPREFIX/sbin
+ --libexecdir=DIR program executables EPREFIX/libexec
+ --sysconfdir=DIR read-only single-machine data PREFIX/etc

+Copyright @copyright{} 2000, 2001, 2002, 2007, 2008 Free Software Foundation, Inc.

+
+Everyone is permitted to copy and distribute verbatim copies
+of this license document, but changing it is not allowed.
+@end display
+
+@enumerate 0
+@item
+PREAMBLE
+
+The purpose of this License is to make a manual, textbook, or other
+functional and useful document @dfn{free} in the sense of freedom: to
+assure everyone the effective freedom to copy and redistribute it,
+with or without modifying it, either commercially or noncommercially.
+Secondarily, this License preserves for the author and publisher a way
+to get credit for their work, while not being considered responsible
+for modifications made by others.
+
+This License is a kind of ``copyleft'', which means that derivative
+works of the document must themselves be free in the same sense.  It
+complements the GNU General Public License, which is a copyleft
+license designed for free software.
+
+We have designed this License in order to use it for manuals for free
+software, because free software needs free documentation: a free
+program should come with manuals providing the same freedoms that the
+software does.  But this License is not limited to software manuals;
+it can be used for any textual work, regardless of subject matter or
+whether it is published as a printed book.  We recommend this License
+principally for works whose purpose is instruction or reference.
+
+@item
+APPLICABILITY AND DEFINITIONS
+
+This License applies to any manual or other work, in any medium, that
+contains a notice placed by the copyright holder saying it can be
+distributed under the terms of this License.  Such a notice grants a
+world-wide, royalty-free license, unlimited in duration, to use that
+work under the conditions stated herein.  The ``Document'', below,
+refers to any such manual or work.  Any member of the public is a
+licensee, and is addressed as ``you''.  You accept the license if you
+copy, modify or distribute the work in a way requiring permission
+under copyright law.
+
+A ``Modified Version'' of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with
+modifications and/or translated into another language.
+
+A ``Secondary Section'' is a named appendix or a front-matter section
+of the Document that deals exclusively with the relationship of the
+publishers or authors of the Document to the Document's overall
+subject (or to related matters) and contains nothing that could fall
+directly within that overall subject.  (Thus, if the Document is in
+part a textbook of mathematics, a Secondary Section may not explain
+any mathematics.)  The relationship could be a matter of historical
+connection with the subject or with related matters, or of legal,
+commercial, philosophical, ethical or political position regarding
+them.
+
+The ``Invariant Sections'' are certain Secondary Sections whose titles
+are designated, as being those of Invariant Sections, in the notice
+that says that the Document is released under this License.  If a
+section does not fit the above definition of Secondary then it is not
+allowed to be designated as Invariant.  The Document may contain zero
+Invariant Sections.  If the Document does not identify any Invariant
+Sections then there are none.
+
+The ``Cover Texts'' are certain short passages of text that are listed,
+as Front-Cover Texts or Back-Cover Texts, in the notice that says that
+the Document is released under this License.  A Front-Cover Text may
+be at most 5 words, and a Back-Cover Text may be at most 25 words.
+
+A ``Transparent'' copy of the Document means a machine-readable copy,
+represented in a format whose specification is available to the
+general public, that is suitable for revising the document
+straightforwardly with generic text editors or (for images composed of
+pixels) generic paint programs or (for drawings) some widely available
+drawing editor, and that is suitable for input to text formatters or
+for automatic translation to a variety of formats suitable for input
+to text formatters.  A copy made in an otherwise Transparent file
+format whose markup, or absence of markup, has been arranged to thwart
+or discourage subsequent modification by readers is not Transparent.
+An image format is not Transparent if used for any substantial amount
+of text.  A copy that is not ``Transparent'' is called ``Opaque''.
+
+Examples of suitable formats for Transparent copies include plain
+@sc{ascii} without markup, Texinfo input format, La@TeX{} input
+format, @acronym{SGML} or @acronym{XML} using a publicly available
+@acronym{DTD}, and standard-conforming simple @acronym{HTML},
+PostScript or @acronym{PDF} designed for human modification.  Examples
+of transparent image formats include @acronym{PNG}, @acronym{XCF} and
+@acronym{JPG}.  Opaque formats include proprietary formats that can be
+read and edited only by proprietary word processors, @acronym{SGML} or
+@acronym{XML} for which the @acronym{DTD} and/or processing tools are
+not generally available, and the machine-generated @acronym{HTML},
+PostScript or @acronym{PDF} produced by some word processors for
+output purposes only.
+
+The ``Title Page'' means, for a printed book, the title page itself,
+plus such following pages as are needed to hold, legibly, the material
+this License requires to appear in the title page.  For works in
+formats which do not have any title page as such, ``Title Page'' means
+the text near the most prominent appearance of the work's title,
+preceding the beginning of the body of the text.
+
+The ``publisher'' means any person or entity that distributes copies
+of the Document to the public.
+
+A section ``Entitled XYZ'' means a named subunit of the Document whose
+title either is precisely XYZ or contains XYZ in parentheses following
+text that translates XYZ in another language.  (Here XYZ stands for a
+specific section name mentioned below, such as ``Acknowledgements'',
+``Dedications'', ``Endorsements'', or ``History''.)  To ``Preserve the Title''
+of such a section when you modify the Document means that it remains a
+section ``Entitled XYZ'' according to this definition.
+
+The Document may include Warranty Disclaimers next to the notice which
+states that this License applies to the Document.  These Warranty
+Disclaimers are considered to be included by reference in this
+License, but only as regards disclaiming warranties: any other
+implication that these Warranty Disclaimers may have is void and has
+no effect on the meaning of this License.
+
+@item
+VERBATIM COPYING
+
+You may copy and distribute the Document in any medium, either
+commercially or noncommercially, provided that this License, the
+copyright notices, and the license notice saying this License applies
+to the Document are reproduced in all copies, and that you add no other
+conditions whatsoever to those of this License.  You may not use
+technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute.  However, you may accept
+compensation in exchange for copies.  If you distribute a large enough
+number of copies you must also follow the conditions in section 3.
+
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+
+@item
+COPYING IN QUANTITY
+
+If you publish printed copies (or copies in media that commonly have
+printed covers) of the Document, numbering more than 100, and the
+Document's license notice requires Cover Texts, you must enclose the
+copies in covers that carry, clearly and legibly, all these Cover
+Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
+the back cover.  Both covers must also clearly and legibly identify
+you as the publisher of these copies.  The front cover must present
+the full title with all words of the title equally prominent and
+visible.  You may add other material on the covers in addition.
+Copying with changes limited to the covers, as long as they preserve
+the title of the Document and satisfy these conditions, can be treated
+as verbatim copying in other respects.
+
+If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+
+If you publish or distribute Opaque copies of the Document numbering
+more than 100, you must either include a machine-readable Transparent
+copy along with each Opaque copy, or state in or with each Opaque copy
+a computer-network location from which the general network-using
+public has access to download using public-standard network protocols
+a complete Transparent copy of the Document, free of added material.
+If you use the latter option, you must take reasonably prudent steps,
+when you begin distribution of Opaque copies in quantity, to ensure
+that this Transparent copy will remain thus accessible at the stated
+location until at least one year after the last time you distribute an
+Opaque copy (directly or through your agents or retailers) of that
+edition to the public.
+
+It is requested, but not required, that you contact the authors of the
+Document well before redistributing any large number of copies, to give
+them a chance to provide you with an updated version of the Document.
+
+@item
+MODIFICATIONS
+
+You may copy and distribute a Modified Version of the Document under
+the conditions of sections 2 and 3 above, provided that you release
+the Modified Version under precisely this License, with the Modified
+Version filling the role of the Document, thus licensing distribution
+and modification of the Modified Version to whoever possesses a copy
+of it.  In addition, you must do these things in the Modified Version:
+
+@enumerate A
+@item
+Use in the Title Page (and on the covers, if any) a title distinct
+from that of the Document, and from those of previous versions
+(which should, if there were any, be listed in the History section
+of the Document).  You may use the same title as a previous version
+if the original publisher of that version gives permission.
+
+@item
+List on the Title Page, as authors, one or more persons or entities
+responsible for authorship of the modifications in the Modified
+Version, together with at least five of the principal authors of the
+Document (all of its principal authors, if it has fewer than five),
+unless they release you from this requirement.
+
+@item
+State on the Title page the name of the publisher of the
+Modified Version, as the publisher.
+
+@item
+Preserve all the copyright notices of the Document.
+
+@item
+Add an appropriate copyright notice for your modifications
+adjacent to the other copyright notices.
+
+@item
+Include, immediately after the copyright notices, a license notice
+giving the public permission to use the Modified Version under the
+terms of this License, in the form shown in the Addendum below.
+
+@item
+Preserve in that license notice the full lists of Invariant Sections
+and required Cover Texts given in the Document's license notice.
+
+@item
+Include an unaltered copy of this License.
+
+@item
+Preserve the section Entitled ``History'', Preserve its Title, and add
+to it an item stating at least the title, year, new authors, and
+publisher of the Modified Version as given on the Title Page.  If
+there is no section Entitled ``History'' in the Document, create one
+stating the title, year, authors, and publisher of the Document as
+given on its Title Page, then add an item describing the Modified
+Version as stated in the previous sentence.
+
+@item
+Preserve the network location, if any, given in the Document for
+public access to a Transparent copy of the Document, and likewise
+the network locations given in the Document for previous versions
+it was based on.  These may be placed in the ``History'' section.
+You may omit a network location for a work that was published at
+least four years before the Document itself, or if the original
+publisher of the version it refers to gives permission.
+
+@item
+For any section Entitled ``Acknowledgements'' or ``Dedications'', Preserve
+the Title of the section, and preserve in the section all the
+substance and tone of each of the contributor acknowledgements and/or
+dedications given therein.
+
+@item
+Preserve all the Invariant Sections of the Document,
+unaltered in their text and in their titles.  Section numbers
+or the equivalent are not considered part of the section titles.
+
+@item
+Delete any section Entitled ``Endorsements''.  Such a section
+may not be included in the Modified Version.
+
+@item
+Do not retitle any existing section to be Entitled ``Endorsements'' or
+to conflict in title with any Invariant Section.
+
+@item
+Preserve any Warranty Disclaimers.
+@end enumerate
+
+If the Modified Version includes new front-matter sections or
+appendices that qualify as Secondary Sections and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant.  To do this, add their titles to the
+list of Invariant Sections in the Modified Version's license notice.
+These titles must be distinct from any other section titles.
+
+You may add a section Entitled ``Endorsements'', provided it contains
+nothing but endorsements of your Modified Version by various
+parties---for example, statements of peer review or that the text has
+been approved by an organization as the authoritative definition of a
+standard.
+
+You may add a passage of up to five words as a Front-Cover Text, and a
+passage of up to 25 words as a Back-Cover Text, to the end of the list
+of Cover Texts in the Modified Version.  Only one passage of
+Front-Cover Text and one of Back-Cover Text may be added by (or
+through arrangements made by) any one entity.  If the Document already
+includes a cover text for the same cover, previously added by you or
+by arrangement made by the same entity you are acting on behalf of,
+you may not add another; but you may replace the old one, on explicit
+permission from the previous publisher that added the old one.
+
+The author(s) and publisher(s) of the Document do not by this License
+give permission to use their names for publicity for or to assert or
+imply endorsement of any Modified Version.
+
+@item
+COMBINING DOCUMENTS
+
+You may combine the Document with other documents released under this
+License, under the terms defined in section 4 above for modified
+versions, provided that you include in the combination all of the
+Invariant Sections of all of the original documents, unmodified, and
+list them all as Invariant Sections of your combined work in its
+license notice, and that you preserve all their Warranty Disclaimers.
+
+The combined work need only contain one copy of this License, and
+multiple identical Invariant Sections may be replaced with a single
+copy.  If there are multiple Invariant Sections with the same name but
+different contents, make the title of each such section unique by
+adding at the end of it, in parentheses, the name of the original
+author or publisher of that section if known, or else a unique number.
+Make the same adjustment to the section titles in the list of
+Invariant Sections in the license notice of the combined work.
+
+In the combination, you must combine any sections Entitled ``History''
+in the various original documents, forming one section Entitled
+``History''; likewise combine any sections Entitled ``Acknowledgements'',
+and any sections Entitled ``Dedications''.  You must delete all
+sections Entitled ``Endorsements.''
+
+@item
+COLLECTIONS OF DOCUMENTS
+
+You may make a collection consisting of the Document and other documents
+released under this License, and replace the individual copies of this
+License in the various documents with a single copy that is included in
+the collection, provided that you follow the rules of this License for
+verbatim copying of each of the documents in all other respects.
+
+You may extract a single document from such a collection, and distribute
+it individually under this License, provided you insert a copy of this
+License into the extracted document, and follow this License in all
+other respects regarding verbatim copying of that document.
+
+@item
+AGGREGATION WITH INDEPENDENT WORKS
+
+A compilation of the Document or its derivatives with other separate
+and independent documents or works, in or on a volume of a storage or
+distribution medium, is called an ``aggregate'' if the copyright
+resulting from the compilation is not used to limit the legal rights
+of the compilation's users beyond what the individual works permit.
+When the Document is included in an aggregate, this License does not
+apply to the other works in the aggregate which are not themselves
+derivative works of the Document.
+
+If the Cover Text requirement of section 3 is applicable to these
+copies of the Document, then if the Document is less than one half of
+the entire aggregate, the Document's Cover Texts may be placed on
+covers that bracket the Document within the aggregate, or the
+electronic equivalent of covers if the Document is in electronic form.
+Otherwise they must appear on printed covers that bracket the whole
+aggregate.
+
+@item
+TRANSLATION
+
+Translation is considered a kind of modification, so you may
+distribute translations of the Document under the terms of section 4.
+Replacing Invariant Sections with translations requires special
+permission from their copyright holders, but you may include
+translations of some or all Invariant Sections in addition to the
+original versions of these Invariant Sections.  You may include a
+translation of this License, and all the license notices in the
+Document, and any Warranty Disclaimers, provided that you also include
+the original English version of this License and the original versions
+of those notices and disclaimers.  In case of a disagreement between
+the translation and the original version of this License or a notice
+or disclaimer, the original version will prevail.
+
+If a section in the Document is Entitled ``Acknowledgements'',
+``Dedications'', or ``History'', the requirement (section 4) to Preserve
+its Title (section 1) will typically require changing the actual
+title.
+
+@item
+TERMINATION
+
+You may not copy, modify, sublicense, or distribute the Document
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense, or distribute it is void, and
+will automatically terminate your rights under this License.
+
+However, if you cease all violation of this License, then your license
+from a particular copyright holder is reinstated (a) provisionally,
+unless and until the copyright holder explicitly and finally
+terminates your license, and (b) permanently, if the copyright holder
+fails to notify you of the violation by some reasonable means prior to
+60 days after the cessation.
+
+Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, receipt of a copy of some or all of the same material does
+not give you any rights to use it.

+@item
+FUTURE REVISIONS OF THIS LICENSE
+
+The Free Software Foundation may publish new, revised versions
+of the GNU Free Documentation License from time to time.  Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.  See
+@uref{http://www.gnu.org/copyleft/}.
+
+Each version of the License is given a distinguishing version number.
+If the Document specifies that a particular numbered version of this
+License ``or any later version'' applies to it, you have the option of
+following the terms and conditions either of that specified version or
+of any later version that has been published (not as a draft) by the
+Free Software Foundation.  If the Document does not specify a version
+number of this License, you may choose any version ever published (not
+as a draft) by the Free Software Foundation.  If the Document
+specifies that a proxy can decide which future versions of this
+License can be used, that proxy's public statement of acceptance of a
+version permanently authorizes you to choose that version for the
+Document.

+
+&#x1b;1mNAME&#x1b;0m
+ history - GNU History Library
+
+&#x1b;1mCOPYRIGHT&#x1b;0m
+ The GNU History Library is Copyright (C) 1989-2020 by the Free Software
+ Foundation, Inc.
+
+&#x1b;1mDESCRIPTION&#x1b;0m
+ Many programs read input from the user a line at a time. The GNU His-
+ tory library is able to keep track of those lines, associate arbitrary
+ data with each line, and utilize information from previous lines in
+ composing new ones.
+
+&#x1b;1mHISTORY EXPANSION&#x1b;0m
+ The history library supports a history expansion feature that is iden-
+ tical to the history expansion in &#x1b;1mbash. &#x1b;22mThis section describes what
+ syntax features are available.
+
+ History expansions introduce words from the history list into the input
+ stream, making it easy to repeat commands, insert the arguments to a
+ previous command into the current input line, or fix errors in previous
+ commands quickly.
+
+ History expansion is usually performed immediately after a complete
+ line is read. It takes place in two parts. The first is to determine
+ which line from the history list to use during substitution. The sec-
+ ond is to select portions of that line for inclusion into the current
+ one. The line selected from the history is the &#x1b;4mevent&#x1b;24m, and the portions
+ of that line that are acted upon are &#x1b;4mwords&#x1b;24m. Various &#x1b;4mmodifiers&#x1b;24m are
+ available to manipulate the selected words. The line is broken into
+ words in the same fashion as &#x1b;1mbash &#x1b;22mdoes when reading input, so that sev-
+ eral words that would otherwise be separated are considered one word
+ when surrounded by quotes (see the description of &#x1b;1mhistory_tokenize()&#x1b;0m
+ below). History expansions are introduced by the appearance of the
+ history expansion character, which is &#x1b;1m! &#x1b;22mby default. Only backslash (&#x1b;1m\&#x1b;22m)
+ and single quotes can quote the history expansion character.
+
+ &#x1b;1mEvent Designators&#x1b;0m
+ An event designator is a reference to a command line entry in the his-
+ tory list. Unless the reference is absolute, events are relative to
+ the current position in the history list.
+
+ &#x1b;1m! &#x1b;22mStart a history substitution, except when followed by a &#x1b;1mblank&#x1b;22m,
+ newline, = or (.
+ &#x1b;1m!&#x1b;4m&#x1b;22mn&#x1b;24m Refer to command line &#x1b;4mn&#x1b;24m.
+ &#x1b;1m!-&#x1b;4m&#x1b;22mn&#x1b;24m Refer to the current command minus &#x1b;4mn&#x1b;24m.
+ &#x1b;1m!! &#x1b;22mRefer to the previous command. This is a synonym for `!-1'.
+ &#x1b;1m!&#x1b;4m&#x1b;22mstring&#x1b;0m
+ Refer to the most recent command preceding the current position
+ in the history list starting with &#x1b;4mstring&#x1b;24m.
+ &#x1b;1m!?&#x1b;4m&#x1b;22mstring&#x1b;24m&#x1b;1m?&#x1b;0m
+ Refer to the most recent command preceding the current position
+ in the history list containing &#x1b;4mstring&#x1b;24m. The trailing &#x1b;1m? &#x1b;22mmay be
+ omitted if &#x1b;4mstring&#x1b;24m is followed immediately by a newline. If
+ &#x1b;4mstring&#x1b;24m is missing, the string from the most recent search is
+ used; it is an error if there is no previous search string.
+ &#x1b;1m^&#x1b;4m&#x1b;22mstring1&#x1b;24m&#x1b;1m^&#x1b;4m&#x1b;22mstring2&#x1b;24m&#x1b;1m^&#x1b;0m
+ Quick substitution. Repeat the last command, replacing &#x1b;4mstring1&#x1b;0m
+ with &#x1b;4mstring2&#x1b;24m. Equivalent to ``!!:s^&#x1b;4mstring1&#x1b;24m^&#x1b;4mstring2&#x1b;24m^'' (see &#x1b;1mMod-&#x1b;0m
+ &#x1b;1mifiers &#x1b;22mbelow).
+ &#x1b;1m!# &#x1b;22mThe entire command line typed so far.
+
+ &#x1b;1mWord Designators&#x1b;0m
+ Word designators are used to select desired words from the event. A &#x1b;1m:&#x1b;0m
+ separates the event specification from the word designator. It may be
+ omitted if the word designator begins with a &#x1b;1m^&#x1b;22m, &#x1b;1m$&#x1b;22m, &#x1b;1m*&#x1b;22m, &#x1b;1m-&#x1b;22m, or &#x1b;1m%&#x1b;22m. Words
+ are numbered from the beginning of the line, with the first word being
+ denoted by 0 (zero). Words are inserted into the current line sepa-
+ rated by single spaces.
+
+ &#x1b;1m0 (zero)&#x1b;0m
+ The zeroth word. For the shell, this is the command word.
+ &#x1b;4mn&#x1b;24m The &#x1b;4mn&#x1b;24mth word.
+ &#x1b;1m^ &#x1b;22mThe first argument. That is, word 1.
+ &#x1b;1m$ &#x1b;22mThe last word. This is usually the last argument, but will ex-
+ pand to the zeroth word if there is only one word in the line.
+ &#x1b;1m% &#x1b;22mThe first word matched by the most recent `?&#x1b;4mstring&#x1b;24m?' search, if
+ the search string begins with a character that is part of a
+ word.
+ &#x1b;4mx&#x1b;24m&#x1b;1m-&#x1b;4m&#x1b;22my&#x1b;24m A range of words; `-&#x1b;4my&#x1b;24m' abbreviates `0-&#x1b;4my&#x1b;24m'.
+ &#x1b;1m* &#x1b;22mAll of the words but the zeroth. This is a synonym for `&#x1b;4m1-$&#x1b;24m'.
+ It is not an error to use &#x1b;1m* &#x1b;22mif there is just one word in the
+ event; the empty string is returned in that case.
+ &#x1b;1mx* &#x1b;22mAbbreviates &#x1b;4mx-$&#x1b;24m.
+ &#x1b;1mx- &#x1b;22mAbbreviates &#x1b;4mx-$&#x1b;24m like &#x1b;1mx*&#x1b;22m, but omits the last word. If &#x1b;1mx &#x1b;22mis miss-
+ ing, it defaults to 0.
+
+ If a word designator is supplied without an event specification, the
+ previous command is used as the event.
+
+ &#x1b;1mModifiers&#x1b;0m
+ After the optional word designator, there may appear a sequence of one
+ or more of the following modifiers, each preceded by a `:'. These mod-
+ ify, or edit, the word or words selected from the history event.
+
+ &#x1b;1mh &#x1b;22mRemove a trailing file name component, leaving only the head.
+ &#x1b;1mt &#x1b;22mRemove all leading file name components, leaving the tail.
+ &#x1b;1mr &#x1b;22mRemove a trailing suffix of the form &#x1b;4m.xxx&#x1b;24m, leaving the basename.
+ &#x1b;1me &#x1b;22mRemove all but the trailing suffix.
+ &#x1b;1mp &#x1b;22mPrint the new command but do not execute it.
+ &#x1b;1mq &#x1b;22mQuote the substituted words, escaping further substitutions.
+ &#x1b;1mx &#x1b;22mQuote the substituted words as with &#x1b;1mq&#x1b;22m, but break into words at
+ &#x1b;1mblanks &#x1b;22mand newlines. The &#x1b;1mq &#x1b;22mand &#x1b;1mx &#x1b;22mmodifiers are mutually exclu-
+ sive; the last one supplied is used.
+ &#x1b;1ms/&#x1b;4m&#x1b;22mold&#x1b;24m&#x1b;1m/&#x1b;4m&#x1b;22mnew&#x1b;24m&#x1b;1m/&#x1b;0m
+ Substitute &#x1b;4mnew&#x1b;24m for the first occurrence of &#x1b;4mold&#x1b;24m in the event
+ line. Any character may be used as the delimiter in place of /.
+ The final delimiter is optional if it is the last character of
+ the event line. The delimiter may be quoted in &#x1b;4mold&#x1b;24m and &#x1b;4mnew&#x1b;24m with
+ a single backslash. If & appears in &#x1b;4mnew&#x1b;24m, it is replaced by &#x1b;4mold&#x1b;24m.
+ A single backslash will quote the &. If &#x1b;4mold&#x1b;24m is null, it is set
+ to the last &#x1b;4mold&#x1b;24m substituted, or, if no previous history substi-
+ tutions took place, the last &#x1b;4mstring&#x1b;24m in a &#x1b;1m!?&#x1b;4m&#x1b;22mstring&#x1b;24m&#x1b;1m? &#x1b;22msearch.
+ If &#x1b;4mnew&#x1b;24m is null, each matching &#x1b;4mold&#x1b;24m is deleted.
+ &#x1b;1m& &#x1b;22mRepeat the previous substitution.
+ &#x1b;1mg &#x1b;22mCause changes to be applied over the entire event line. This is
+ used in conjunction with `&#x1b;1m:s&#x1b;22m' (e.g., `&#x1b;1m:gs/&#x1b;4m&#x1b;22mold&#x1b;24m&#x1b;1m/&#x1b;4m&#x1b;22mnew&#x1b;24m&#x1b;1m/&#x1b;22m') or `&#x1b;1m:&&#x1b;22m'.
+ If used with `&#x1b;1m:s&#x1b;22m', any delimiter can be used in place of /, and
+ the final delimiter is optional if it is the last character of
+ the event line. An &#x1b;1ma &#x1b;22mmay be used as a synonym for &#x1b;1mg&#x1b;22m.
+ &#x1b;1mG &#x1b;22mApply the following `&#x1b;1ms&#x1b;22m' or `&#x1b;1m&&#x1b;22m' modifier once to each word in the
+ event line.
+
+&#x1b;1mPROGRAMMING WITH HISTORY FUNCTIONS&#x1b;0m
+ This section describes how to use the History library in other pro-
+ grams.
+
+ &#x1b;1mIntroduction to History&#x1b;0m
+ A programmer using the History library has available functions for re-
+ membering lines on a history list, associating arbitrary data with a
+ line, removing lines from the list, searching through the list for a
+ line containing an arbitrary text string, and referencing any line in
+ the list directly. In addition, a history &#x1b;4mexpansion&#x1b;24m function is avail-
+ able which provides for a consistent user interface across different
+ programs.
+
+ The user using programs written with the History library has the bene-
+ fit of a consistent user interface with a set of well-known commands
+ for manipulating the text of previous lines and using that text in new
+ commands. The basic history manipulation commands are identical to the
+ history substitution provided by &#x1b;1mbash&#x1b;22m.
+
+ The programmer can also use the Readline library, which includes some
+ history manipulation by default, and has the added advantage of command
+ line editing.
+
+ Before declaring any functions using any functionality the History li-
+ brary provides in other code, an application writer should include the
+ file &#x1b;4m<readline/history.h>&#x1b;24m in any file that uses the History library's
+ features. It supplies extern declarations for all of the library's
+ public functions and variables, and declares all of the public data
+ structures.
+
+ &#x1b;1mHistory Storage&#x1b;0m
+ The history list is an array of history entries. A history entry is

+ Place &#x1b;4mstring&#x1b;24m at the end of the history list. The associated data field
+ (if any) is set to &#x1b;1mNULL&#x1b;22m. If the maximum number of history entries has
+ been set using &#x1b;1mstifle_history()&#x1b;22m, and the new number of history entries
+ would exceed that maximum, the oldest history entry is removed.
+
+ &#x1b;4mvoid&#x1b;24m &#x1b;1madd_history_time &#x1b;22m(&#x1b;4mconst&#x1b;24m &#x1b;4mchar&#x1b;24m &#x1b;4m*string&#x1b;24m)

+ sociated with it. Returns the application-specific data so the caller
+ can dispose of it.
+
+ &#x1b;4mHIST_ENTRY&#x1b;24m &#x1b;4m*&#x1b;24m &#x1b;1mreplace_history_entry &#x1b;22m(&#x1b;4mint&#x1b;24m &#x1b;4mwhich,&#x1b;24m &#x1b;4mconst&#x1b;24m &#x1b;4mchar&#x1b;24m &#x1b;4m*line,&#x1b;24m &#x1b;4mhist-&#x1b;0m

+ Make the history entry at offset &#x1b;4mwhich&#x1b;24m have &#x1b;4mline&#x1b;24m and &#x1b;4mdata&#x1b;24m. This re-
+ turns the old entry so the caller can dispose of any application-spe-
+ cific data. In the case of an invalid &#x1b;4mwhich&#x1b;24m, a &#x1b;1mNULL &#x1b;22mpointer is re-
+ turned.

+ Stifle the history list, remembering only the last &#x1b;4mmax&#x1b;24m entries. The
+ history list will contain only &#x1b;4mmax&#x1b;24m entries at a time.
+
+ &#x1b;4mint&#x1b;24m &#x1b;1munstifle_history &#x1b;22m(&#x1b;4mvoid&#x1b;24m)
+ Stop stifling the history. This returns the previously-set maximum
+ number of history entries (as set by &#x1b;1mstifle_history()&#x1b;22m). history was
+ stifled. The value is positive if the history was stifled, negative if
+ it wasn't.

+
+
+ &#x1b;1mInformation About the History List&#x1b;0m
+ These functions return information about the entire history list or in-
+ dividual list entries.
+
+ &#x1b;4mHIST_ENTRY&#x1b;24m &#x1b;4m**&#x1b;24m &#x1b;1mhistory_list &#x1b;22m(&#x1b;4mvoid&#x1b;24m)
+ Return a &#x1b;1mNULL &#x1b;22mterminated array of &#x1b;4mHIST_ENTRY&#x1b;24m &#x1b;4m*&#x1b;24m which is the current in-

+ Return the history entry at the current position, as determined by
+ &#x1b;1mwhere_history()&#x1b;22m. If there is no entry there, return a &#x1b;1mNULL &#x1b;22mpointer.
+
+ &#x1b;4mHIST_ENTRY&#x1b;24m &#x1b;4m*&#x1b;24m &#x1b;1mhistory_get &#x1b;22m(&#x1b;4mint&#x1b;24m &#x1b;4moffset&#x1b;24m)
+ Return the history entry at position &#x1b;4moffset&#x1b;24m. The range of valid values
+ of &#x1b;4moffset&#x1b;24m starts at &#x1b;1mhistory_base &#x1b;22mand ends at &#x1b;1mhistory_length &#x1b;22m- 1. If
+ there is no entry there, or if &#x1b;4moffset&#x1b;24m is outside the valid range, re-
+ turn a &#x1b;1mNULL &#x1b;22mpointer.
+
+ &#x1b;4mtime_t&#x1b;24m &#x1b;1mhistory_get_time &#x1b;22m(&#x1b;4mHIST_ENTRY&#x1b;24m &#x1b;4m*&#x1b;24m)
+ Return the time stamp associated with the history entry passed as the
+ argument.
+
+ &#x1b;4mint&#x1b;24m &#x1b;1mhistory_total_bytes &#x1b;22m(&#x1b;4mvoid&#x1b;24m)
+ Return the number of bytes that the primary history entries are using.
+ This function returns the sum of the lengths of all the lines in the
+ history.
+
+
+ &#x1b;1mMoving Around the History List&#x1b;0m
+ These functions allow the current index into the history list to be set
+ or changed.
+
+ &#x1b;4mint&#x1b;24m &#x1b;1mhistory_set_pos &#x1b;22m(&#x1b;4mint&#x1b;24m &#x1b;4mpos&#x1b;24m)
+ Set the current history offset to &#x1b;4mpos&#x1b;24m, an absolute index into the list.

+
+ &#x1b;4mHIST_ENTRY&#x1b;24m &#x1b;4m*&#x1b;24m &#x1b;1mprevious_history &#x1b;22m(&#x1b;4mvoid&#x1b;24m)
+ Back up the current history offset to the previous history entry, and
+ return a pointer to that entry. If there is no previous entry, return

+ If the current history offset refers to a valid history entry, incre-
+ ment the current history offset. If the possibly-incremented history
+ offset refers to a valid history entry, return a pointer to that entry;
+ otherwise, return a &#x1b;1mNULL &#x1b;22mpointer.
+
+
+ &#x1b;1mSearching the History List&#x1b;0m
+ These functions allow searching of the history list for entries con-
+ taining a specific string. Searching may be performed both forward and
+ backward from the current history position. The search may be &#x1b;4man-&#x1b;0m
+ &#x1b;4mchored&#x1b;24m, meaning that the string must match at the beginning of the his-
+ tory entry.
+
+ &#x1b;4mint&#x1b;24m &#x1b;1mhistory_search &#x1b;22m(&#x1b;4mconst&#x1b;24m &#x1b;4mchar&#x1b;24m &#x1b;4m*string,&#x1b;24m &#x1b;4mint&#x1b;24m &#x1b;4mdirection&#x1b;24m)
+ Search the history for &#x1b;4mstring&#x1b;24m, starting at the current history offset.
+ If &#x1b;4mdirection&#x1b;24m is less than 0, then the search is through previous en-
+ tries, otherwise through subsequent entries. If &#x1b;4mstring&#x1b;24m is found, then
+ the current history index is set to that history entry, and the value
+ returned is the offset in the line of the entry where &#x1b;4mstring&#x1b;24m was found.
+ Otherwise, nothing is changed, and a -1 is returned.
+
+ &#x1b;4mint&#x1b;24m &#x1b;1mhistory_search_prefix &#x1b;22m(&#x1b;4mconst&#x1b;24m &#x1b;4mchar&#x1b;24m &#x1b;4m*string,&#x1b;24m &#x1b;4mint&#x1b;24m &#x1b;4mdirection&#x1b;24m)
+ Search the history for &#x1b;4mstring&#x1b;24m, starting at the current history offset.
+ The search is anchored: matching lines must begin with &#x1b;4mstring&#x1b;24m. If &#x1b;4mdi-&#x1b;0m
+ &#x1b;4mrection&#x1b;24m is less than 0, then the search is through previous entries,
+ otherwise through subsequent entries. If &#x1b;4mstring&#x1b;24m is found, then the
+ current history index is set to that entry, and the return value is 0.
+ Otherwise, nothing is changed, and a -1 is returned.
+
+ &#x1b;4mint&#x1b;24m &#x1b;1mhistory_search_pos &#x1b;22m(&#x1b;4mconst&#x1b;24m &#x1b;4mchar&#x1b;24m &#x1b;4m*string,&#x1b;24m &#x1b;4mint&#x1b;24m &#x1b;4mdirection,&#x1b;24m &#x1b;4mint&#x1b;24m &#x1b;4mpos&#x1b;24m)
+ Search for &#x1b;4mstring&#x1b;24m in the history list, starting at &#x1b;4mpos&#x1b;24m, an absolute in-
+ dex into the list. If &#x1b;4mdirection&#x1b;24m is negative, the search proceeds back-
+ ward from &#x1b;4mpos&#x1b;24m, otherwise forward. Returns the absolute index of the
+ history element where &#x1b;4mstring&#x1b;24m was found, or -1 otherwise.
+
+
+ &#x1b;1mManaging the History File&#x1b;0m
+ The History library can read the history from and write it to a file.
+ This section documents the functions for managing a history file.

+
+ &#x1b;4mint&#x1b;24m &#x1b;1mread_history_range &#x1b;22m(&#x1b;4mconst&#x1b;24m &#x1b;4mchar&#x1b;24m &#x1b;4m*filename,&#x1b;24m &#x1b;4mint&#x1b;24m &#x1b;4mfrom,&#x1b;24m &#x1b;4mint&#x1b;24m &#x1b;4mto&#x1b;24m)
+ Read a range of lines from &#x1b;4mfilename&#x1b;24m, adding them to the history list.
+ Start reading at line &#x1b;4mfrom&#x1b;24m and end at &#x1b;4mto&#x1b;24m. If &#x1b;4mfrom&#x1b;24m is zero, start at
+ the beginning. If &#x1b;4mto&#x1b;24m is less than &#x1b;4mfrom&#x1b;24m, then read until the end of the
+ file. If &#x1b;4mfilename&#x1b;24m is &#x1b;1mNULL&#x1b;22m, then read from &#x1b;4m~/.history&#x1b;24m. Returns 0 if

+ Write the current history to &#x1b;4mfilename&#x1b;24m, overwriting &#x1b;4mfilename&#x1b;24m if neces-
+ sary. If &#x1b;4mfilename&#x1b;24m is &#x1b;1mNULL&#x1b;22m, then write the history list to &#x1b;4m~/.history&#x1b;24m.
+ Returns 0 on success, or &#x1b;1merrno &#x1b;22mon a read or write error.
+
+
+ &#x1b;4mint&#x1b;24m &#x1b;1mappend_history &#x1b;22m(&#x1b;4mint&#x1b;24m &#x1b;4mnelements,&#x1b;24m &#x1b;4mconst&#x1b;24m &#x1b;4mchar&#x1b;24m &#x1b;4m*filename&#x1b;24m)
+ Append the last &#x1b;4mnelements&#x1b;24m of the history list to &#x1b;4mfilename&#x1b;24m. If &#x1b;4mfilename&#x1b;0m
+ is &#x1b;1mNULL&#x1b;22m, then append to &#x1b;4m~/.history&#x1b;24m. Returns 0 on success, or &#x1b;1merrno &#x1b;22mon
+ a read or write error.
+
+ &#x1b;4mint&#x1b;24m &#x1b;1mhistory_truncate_file &#x1b;22m(&#x1b;4mconst&#x1b;24m &#x1b;4mchar&#x1b;24m &#x1b;4m*filename,&#x1b;24m &#x1b;4mint&#x1b;24m &#x1b;4mnlines&#x1b;24m)
+ Truncate the history file &#x1b;4mfilename&#x1b;24m, leaving only the last &#x1b;4mnlines&#x1b;24m lines.
+ If &#x1b;4mfilename&#x1b;24m is &#x1b;1mNULL&#x1b;22m, then &#x1b;4m~/.history&#x1b;24m is truncated. Returns 0 on suc-
+ cess, or &#x1b;1merrno &#x1b;22mon failure.
+
+
+ &#x1b;1mHistory Expansion&#x1b;0m
+ These functions implement history expansion.
+
+ &#x1b;4mint&#x1b;24m &#x1b;1mhistory_expand &#x1b;22m(&#x1b;4mchar&#x1b;24m &#x1b;4m*string,&#x1b;24m &#x1b;4mchar&#x1b;24m &#x1b;4m**output&#x1b;24m)
+ Expand &#x1b;4mstring&#x1b;24m, placing the result into &#x1b;4moutput&#x1b;24m, a pointer to a string.
+ Returns:
+ 0 If no expansions took place (or, if the only change in
+ the text was the removal of escape characters preceding
+ the history expansion character);
+ 1 if expansions did take place;
+ -1 if there was an error in expansion;
+ 2 if the returned line should be displayed, but not exe-
+ cuted, as with the &#x1b;1m:p &#x1b;22mmodifier.
+ If an error occurred in expansion, then &#x1b;4moutput&#x1b;24m contains a descriptive
+ error message.
+
+ &#x1b;4mchar&#x1b;24m &#x1b;4m*&#x1b;24m &#x1b;1mget_history_event &#x1b;22m(&#x1b;4mconst&#x1b;24m &#x1b;4mchar&#x1b;24m &#x1b;4m*string,&#x1b;24m &#x1b;4mint&#x1b;24m &#x1b;4m*cindex,&#x1b;24m &#x1b;4mint&#x1b;24m &#x1b;4mqchar&#x1b;24m)
+ Returns the text of the history event beginning at &#x1b;4mstring&#x1b;24m + &#x1b;4m*cindex&#x1b;24m.
+ &#x1b;4m*cindex&#x1b;24m is modified to point to after the event specifier. At function
+ entry, &#x1b;4mcindex&#x1b;24m points to the index into &#x1b;4mstring&#x1b;24m where the history event
+ specification begins. &#x1b;4mqchar&#x1b;24m is a character that is allowed to end the
+ event specification in addition to the ``normal'' terminating charac-

+ Return an array of tokens parsed out of &#x1b;4mstring&#x1b;24m, much as the shell
+ might. The tokens are split on the characters in the &#x1b;1mhistory_word_de-&#x1b;0m
+ &#x1b;1mlimiters &#x1b;22mvariable, and shell quoting conventions are obeyed.
+
+ &#x1b;4mchar&#x1b;24m &#x1b;4m*&#x1b;24m &#x1b;1mhistory_arg_extract &#x1b;22m(&#x1b;4mint&#x1b;24m &#x1b;4mfirst,&#x1b;24m &#x1b;4mint&#x1b;24m &#x1b;4mlast,&#x1b;24m &#x1b;4mconst&#x1b;24m &#x1b;4mchar&#x1b;24m &#x1b;4m*string&#x1b;24m)
+ Extract a string segment consisting of the &#x1b;4mfirst&#x1b;24m through &#x1b;4mlast&#x1b;24m arguments
+ present in &#x1b;4mstring&#x1b;24m. Arguments are split using &#x1b;1mhistory_tokenize()&#x1b;22m.
+
+
+ &#x1b;1mHistory Variables&#x1b;0m
+ This section describes the externally-visible variables exported by the
+ GNU History Library.
+
+ &#x1b;4mint&#x1b;24m &#x1b;1mhistory_base&#x1b;0m
+ The logical offset of the first entry in the history list.
+
+ &#x1b;4mint&#x1b;24m &#x1b;1mhistory_length&#x1b;0m
+ The number of entries currently stored in the history list.
+
+ &#x1b;4mint&#x1b;24m &#x1b;1mhistory_max_entries&#x1b;0m
+ The maximum number of history entries. This must be changed using &#x1b;1msti-&#x1b;0m
+ &#x1b;1mfle_history()&#x1b;22m.
+
+ &#x1b;4mint&#x1b;24m &#x1b;1mhistory_write_timestamps&#x1b;0m
+ If non-zero, timestamps are written to the history file, so they can be
+ preserved between sessions. The default value is 0, meaning that time-
+ stamps are not saved. The current timestamp format uses the value of
+ &#x1b;4mhistory_comment_char&#x1b;24m to delimit timestamp entries in the history file.
+ If that variable does not have a value (the default), timestamps will
+ not be written.
+
+ &#x1b;4mchar&#x1b;24m &#x1b;1mhistory_expansion_char&#x1b;0m
+ The character that introduces a history event. The default is &#x1b;1m!&#x1b;22m. Set-
+ ting this to 0 inhibits history expansion.
+
+ &#x1b;4mchar&#x1b;24m &#x1b;1mhistory_subst_char&#x1b;0m
+ The character that invokes word substitution if found at the start of a
+ line. The default is &#x1b;1m^&#x1b;22m.
+
+ &#x1b;4mchar&#x1b;24m &#x1b;1mhistory_comment_char&#x1b;0m
+ During tokenization, if this character is seen as the first character
+ of a word, then it and all subsequent characters up to a newline are
+ ignored, suppressing history expansion for the remainder of the line.
+ This is disabled by default.
+
+ &#x1b;4mchar&#x1b;24m &#x1b;4m*&#x1b;24m &#x1b;1mhistory_word_delimiters&#x1b;0m
+ The characters that separate tokens for &#x1b;1mhistory_tokenize()&#x1b;22m. The de-
+ fault value is &#x1b;1m" \t\n()<>;&|"&#x1b;22m.
+
+ &#x1b;4mchar&#x1b;24m &#x1b;4m*&#x1b;24m &#x1b;1mhistory_no_expand_chars&#x1b;0m
+ The list of characters which inhibit history expansion if found immedi-
+ ately following &#x1b;1mhistory_expansion_char&#x1b;22m. The default is space, tab,
+ newline, &#x1b;1m\r&#x1b;22m, and &#x1b;1m=&#x1b;22m.
+
+ &#x1b;4mchar&#x1b;24m &#x1b;4m*&#x1b;24m &#x1b;1mhistory_search_delimiter_chars&#x1b;0m

+.if n The GNU History Library is Copyright (C) 1989-2020 by the Free Software Foundation, Inc.
+.SH DESCRIPTION
+Many programs read input from the user a line at a time. The GNU
+History library is able to keep track of those lines, associate arbitrary
+data with each line, and utilize information from previous lines in
+composing new ones. 
+.PP
+.SH "HISTORY EXPANSION"
+The history library supports a history expansion feature that
+is identical to the history expansion in
+.BR bash.
+This section describes what syntax features are available.
+.PP
+History expansions introduce words from the history list into
+the input stream, making it easy to repeat commands, insert the
+arguments to a previous command into the current input line, or
+fix errors in previous commands quickly.
+.PP
+History expansion is usually performed immediately after a complete line
+is read.
+It takes place in two parts.
+The first is to determine which line from the history list
+to use during substitution.
+The second is to select portions of that line for inclusion into
+the current one.
+The line selected from the history is the \fIevent\fP,
+and the portions of that line that are acted upon are \fIwords\fP.
+Various \fImodifiers\fP are available to manipulate the selected words.
+The line is broken into words in the same fashion as \fBbash\fP
+does when reading input,
+so that several words that would otherwise be separated 
+are considered one word when surrounded by quotes (see the
+description of \fBhistory_tokenize()\fP below).
+History expansions are introduced by the appearance of the
+history expansion character, which is \^\fB!\fP\^ by default.
+Only backslash (\^\fB\e\fP\^) and single quotes can quote
+the history expansion character.
+.SS Event Designators
+An event designator is a reference to a command line entry in the
+history list.
+Unless the reference is absolute, events are relative to the current
+position in the history list.
+.PP
+.PD 0
+.TP
+.B !
+Start a history substitution, except when followed by a
+.BR blank ,
+newline, = or (.
+.TP
+.B !\fIn\fR
+Refer to command line
+.IR n .
+.TP
+.B !\-\fIn\fR
+Refer to the current command minus
+.IR n .
+.TP
+.B !!
+Refer to the previous command. This is a synonym for `!\-1'.
+.TP
+.B !\fIstring\fR
+Refer to the most recent command
+preceding the current position in the history list
+starting with
+.IR string .
+.TP
+.B !?\fIstring\fR\fB?\fR
+Refer to the most recent command
+preceding the current position in the history list
+containing
+.IR string .
+The trailing \fB?\fP may be omitted if
+.I string
+is followed immediately by a newline.
+If \fIstring\fP is missing, the string from the most recent search is used;
+it is an error if there is no previous search string.
+.TP
+.B \d\s+2^\s-2\u\fIstring1\fP\d\s+2^\s-2\u\fIstring2\fP\d\s+2^\s-2\u
+Quick substitution. Repeat the last command, replacing
+.I string1
+with
+.IR string2 .
+Equivalent to
+``!!:s\d\s+2^\s-2\u\fIstring1\fP\d\s+2^\s-2\u\fIstring2\fP\d\s+2^\s-2\u''
+(see \fBModifiers\fP below).
+.TP
+.B !#
+The entire command line typed so far.
+.PD
+.SS Word Designators
+Word designators are used to select desired words from the event.
+A
+.B :
+separates the event specification from the word designator.
+It may be omitted if the word designator begins with a
+.BR ^ ,
+.BR $ ,
+.BR * ,
+.BR \- ,
+or
+.BR % .
+Words are numbered from the beginning of the line,
+with the first word being denoted by 0 (zero).
+Words are inserted into the current line separated by single spaces.
+.PP
+.PD 0
+.TP
+.B 0 (zero)
+The zeroth word. For the shell, this is the command
+word.
+.TP
+.I n
+The \fIn\fRth word.
+.TP
+.B ^
+The first argument. That is, word 1.
+.TP
+.B $
+The last word. This is usually the last argument, but will expand to the
+zeroth word if there is only one word in the line.
+.TP
+.B %
+The first word matched by the most recent `?\fIstring\fR?' search,
+if the search string begins with a character that is part of a word.
+.TP
+.I x\fB\-\fPy
+A range of words; `\-\fIy\fR' abbreviates `0\-\fIy\fR'.
+.TP
+.B *
+All of the words but the zeroth. This is a synonym
+for `\fI1\-$\fP'. It is not an error to use
+.B *
+if there is just one
+word in the event; the empty string is returned in that case.
+.TP
+.B x*
+Abbreviates \fIx\-$\fP.
+.TP
+.B x\-
+Abbreviates \fIx\-$\fP like \fBx*\fP, but omits the last word.
+If \fBx\fP is missing, it defaults to 0.
+.PD
+.PP
+If a word designator is supplied without an event specification, the
+previous command is used as the event.
+.SS Modifiers
+After the optional word designator, there may appear a sequence of
+one or more of the following modifiers, each preceded by a `:'.
+These modify, or edit, the word or words selected from the history event.
+.PP
+.PD 0
+.PP
+.TP
+.B h
+Remove a trailing file name component, leaving only the head.
+.TP
+.B t
+Remove all leading file name components, leaving the tail.
+.TP
+.B r
+Remove a trailing suffix of the form \fI.xxx\fP, leaving the
+basename.
+.TP
+.B e
+Remove all but the trailing suffix.
+.TP
+.B p
+Print the new command but do not execute it.
+.TP
+.B q
+Quote the substituted words, escaping further substitutions.
+.TP
+.B x
+Quote the substituted words as with
+.BR q ,
+but break into words at
+.B blanks
+and newlines.
+The \fBq\fP and \fBx\fP modifiers are mutually exclusive; the last one
+supplied is used.
+.TP
+.B s/\fIold\fP/\fInew\fP/
+Substitute
+.I new
+for the first occurrence of
+.I old
+in the event line.
+Any character may be used as the delimiter in place of /.
+The final delimiter is optional if it is the last character of the
+event line.
+The delimiter may be quoted in
+.I old
+and
+.I new
+with a single backslash. If & appears in
+.IR new ,
+it is replaced by
+.IR old .
+A single backslash will quote the &.
+If
+.I old
+is null, it is set to the last
+.I old
+substituted, or, if no previous history substitutions took place,
+the last
+.I string
+in a
+.B !?\fIstring\fR\fB?\fR
+search.
+If
+.I new
+is null, each matching
+.I old
+is deleted.
+.TP
+.B &
+Repeat the previous substitution.
+.TP
+.B g
+Cause changes to be applied over the entire event line. This is
+used in conjunction with `\fB:s\fP' (e.g., `\fB:gs/\fIold\fP/\fInew\fP/\fR')
+or `\fB:&\fP'. If used with
+`\fB:s\fP', any delimiter can be used
+in place of /, and the final delimiter is optional
+if it is the last character of the event line.
+An \fBa\fP may be used as a synonym for \fBg\fP.
+.TP
+.B G
+Apply the following `\fBs\fP' or `\fB&\fP' modifier once to each word
+in the event line.
+.PD
+.SH "PROGRAMMING WITH HISTORY FUNCTIONS"
+This section describes how to use the History library in other programs.
+.SS Introduction to History
+A programmer using the History library has available functions
+for remembering lines on a history list, associating arbitrary data
+with a line, removing lines from the list, searching through the list
+for a line containing an arbitrary text string, and referencing any line
+in the list directly. In addition, a history \fIexpansion\fP function
+is available which provides for a consistent user interface across
+different programs.
+.PP
+The user using programs written with the History library has the
+benefit of a consistent user interface with a set of well-known
+commands for manipulating the text of previous lines and using that text
+in new commands. The basic history manipulation commands are
+identical to
+the history substitution provided by \fBbash\fP.
+.PP
+The programmer can also use the Readline library, which
+includes some history manipulation by default, and has the added
+advantage of command line editing.
+.PP
+Before declaring any functions using any functionality the History
+library provides in other code, an application writer should include
+the file
+.FN <readline/history.h>
+in any file that uses the
+History library's features. It supplies extern declarations for all
+of the library's public functions and variables, and declares all of
+the public data structures.
+.SS History Storage
+The history list is an array of history entries. A history entry is
+declared as follows:
+.PP
+.Vb "typedef void *" histdata_t;
+.PP
+.nf
+typedef struct _hist_entry {
+ char *line;
+ char *timestamp;
+ histdata_t data;
+} HIST_ENTRY;
+.fi
+.PP
+The history list itself might therefore be declared as
+.PP
+.Vb "HIST_ENTRY **" the_history_list;
+.PP
+The state of the History library is encapsulated into a single structure:
+.PP
+.nf
+/*
+ * A structure used to pass around the current state of the history.
+ */
+typedef struct _hist_state {
+ HIST_ENTRY **entries; /* Pointer to the entries themselves. */
+ int offset; /* The location pointer within this array. */
+ int length; /* Number of elements within this array. */
+ int size; /* Number of slots allocated to this array. */
+ int flags;
+} HISTORY_STATE;
+.fi
+.PP
+If the flags member includes \fBHS_STIFLED\fP, the history has been
+stifled.
+.SH "History Functions"
+This section describes the calling sequence for the various functions
+exported by the GNU History library.
+.SS Initializing History and State Management
+This section describes functions used to initialize and manage
+the state of the History library when you want to use the history
+functions in your program.
+
+.Fn1 void using_history void
+Begin a session in which the history functions might be used. This
+initializes the interactive variables.
+
+.Fn1 "HISTORY_STATE *" history_get_history_state void
+Return a structure describing the current state of the input history.
+
+.Fn1 void history_set_history_state "HISTORY_STATE *state"
+Set the state of the history list according to \fIstate\fP.
+
+.SS History List Management
+These functions manage individual entries on the history list, or set
+parameters managing the list itself.
+
+.Fn1 void add_history "const char *string"
+Place \fIstring\fP at the end of the history list. The associated data
+field (if any) is set to \fBNULL\fP.
+If the maximum number of history entries has been set using
+\fBstifle_history()\fP, and the new number of history entries would exceed
+that maximum, the oldest history entry is removed.
+
+.Fn1 void add_history_time "const char *string"
+Change the time stamp associated with the most recent history entry to
+\fIstring\fP.
+
+.Fn1 "HIST_ENTRY *" remove_history "int which"
+Remove history entry at offset \fIwhich\fP from the history. The
+removed element is returned so you can free the line, data,
+and containing structure.
+
+.Fn1 "histdata_t" free_history_entry "HIST_ENTRY *histent"
+Free the history entry \fIhistent\fP and any history library private
+data associated with it. Returns the application-specific data
+so the caller can dispose of it.
+
+.Fn3 "HIST_ENTRY *" replace_history_entry "int which" "const char *line" "histdata_t data"
+Make the history entry at offset \fIwhich\fP have \fIline\fP and \fIdata\fP.
+This returns the old entry so the caller can dispose of any
+application-specific data. In the case
+of an invalid \fIwhich\fP, a \fBNULL\fP pointer is returned.
+
+.Fn1 void clear_history "void"
+Clear the history list by deleting all the entries.
+
+.Fn1 void stifle_history "int max"
+Stifle the history list, remembering only the last \fImax\fP entries.
+The history list will contain only \fImax\fP entries at a time.
+
+.Fn1 int unstifle_history "void"
+Stop stifling the history. This returns the previously-set
+maximum number of history entries (as set by \fBstifle_history()\fP).
+history was stifled. The value is positive if the history was
+stifled, negative if it wasn't.
+
+.Fn1 int history_is_stifled "void"
+Returns non-zero if the history is stifled, zero if it is not.
+
+.SS Information About the History List
+
+These functions return information about the entire history list or
+individual list entries.
+
+.Fn1 "HIST_ENTRY **" history_list "void"
+Return a \fBNULL\fP terminated array of \fIHIST_ENTRY *\fP which is the
+current input history. Element 0 of this list is the beginning of time.
+If there is no history, return \fBNULL\fP.
+
+.Fn1 int where_history "void"
+Returns the offset of the current history element.
+
+.Fn1 "HIST_ENTRY *" current_history "void"
+Return the history entry at the current position, as determined by
+\fBwhere_history()\fP. If there is no entry there, return a \fBNULL\fP
+pointer.
+
+.Fn1 "HIST_ENTRY *" history_get "int offset"
+Return the history entry at position \fIoffset\fP.
+The range of valid values of \fIoffset\fP starts at \fBhistory_base\fP
+and ends at \fBhistory_length\fP \- 1.
+If there is no entry there, or if \fIoffset\fP is outside the valid
+range, return a \fBNULL\fP pointer.
+
+.Fn1 "time_t" history_get_time "HIST_ENTRY *"
+Return the time stamp associated with the history entry passed as the argument.
+
+.Fn1 int history_total_bytes "void"
+Return the number of bytes that the primary history entries are using.
+This function returns the sum of the lengths of all the lines in the
+history.
+
+.SS Moving Around the History List
+
+These functions allow the current index into the history list to be
+set or changed.
+
+.Fn1 int history_set_pos "int pos"
+Set the current history offset to \fIpos\fP, an absolute index
+into the list.
+Returns 1 on success, 0 if \fIpos\fP is less than zero or greater
+than the number of history entries.
+
+.Fn1 "HIST_ENTRY *" previous_history "void"
+Back up the current history offset to the previous history entry, and
+return a pointer to that entry. If there is no previous entry, return
+a \fBNULL\fP pointer.
+
+.Fn1 "HIST_ENTRY *" next_history "void"
+If the current history offset refers to a valid history entry,
+increment the current history offset.
+If the possibly-incremented history offset refers to a valid history
+entry, return a pointer to that entry;
+otherwise, return a \fBNULL\fP pointer.
+
+.SS Searching the History List
+
+These functions allow searching of the history list for entries containing
+a specific string. Searching may be performed both forward and backward
+from the current history position. The search may be \fIanchored\fP,
+meaning that the string must match at the beginning of the history entry.
+
+.Fn2 int history_search "const char *string" "int direction"
+Search the history for \fIstring\fP, starting at the current history offset.
+If \fIdirection\fP is less than 0, then the search is through
+previous entries, otherwise through subsequent entries.
+If \fIstring\fP is found, then
+the current history index is set to that history entry, and the value
+returned is the offset in the line of the entry where
+\fIstring\fP was found. Otherwise, nothing is changed, and a -1 is
+returned.
+
+.Fn2 int history_search_prefix "const char *string" "int direction"
+Search the history for \fIstring\fP, starting at the current history
+offset. The search is anchored: matching lines must begin with
+\fIstring\fP. If \fIdirection\fP is less than 0, then the search is
+through previous entries, otherwise through subsequent entries.
+If \fIstring\fP is found, then the
+current history index is set to that entry, and the return value is 0. 
+Otherwise, nothing is changed, and a -1 is returned. 
+
+.Fn3 int history_search_pos "const char *string" "int direction" "int pos"
+Search for \fIstring\fP in the history list, starting at \fIpos\fP, an
+absolute index into the list. If \fIdirection\fP is negative, the search
+proceeds backward from \fIpos\fP, otherwise forward. Returns the absolute
+index of the history element where \fIstring\fP was found, or -1 otherwise.
+
+.SS Managing the History File
+The History library can read the history from and write it to a file.
+This section documents the functions for managing a history file.
+
+.Fn1 int read_history "const char *filename"
+Add the contents of \fIfilename\fP to the history list, a line at a time.
+If \fIfilename\fP is \fBNULL\fP, then read from \fI~/.history\fP.
+Returns 0 if successful, or \fBerrno\fP if not.
+
+.Fn3 int read_history_range "const char *filename" "int from" "int to"
+Read a range of lines from \fIfilename\fP, adding them to the history list.
+Start reading at line \fIfrom\fP and end at \fIto\fP.
+If \fIfrom\fP is zero, start at the beginning. If \fIto\fP is less than
+\fIfrom\fP, then read until the end of the file. If \fIfilename\fP is
+\fBNULL\fP, then read from \fI~/.history\fP. Returns 0 if successful,
+or \fBerrno\fP if not.
+
+.Fn1 int write_history "const char *filename"
+Write the current history to \fIfilename\fP, overwriting \fIfilename\fP
+if necessary.
+If \fIfilename\fP is \fBNULL\fP, then write the history list to \fI~/.history\fP.
+Returns 0 on success, or \fBerrno\fP on a read or write error.
+
+
+.Fn2 int append_history "int nelements" "const char *filename"
+Append the last \fInelements\fP of the history list to \fIfilename\fP.
+If \fIfilename\fP is \fBNULL\fP, then append to \fI~/.history\fP.
+Returns 0 on success, or \fBerrno\fP on a read or write error.
+
+.Fn2 int history_truncate_file "const char *filename" "int nlines"
+Truncate the history file \fIfilename\fP, leaving only the last
+\fInlines\fP lines.
+If \fIfilename\fP is \fBNULL\fP, then \fI~/.history\fP is truncated.
+Returns 0 on success, or \fBerrno\fP on failure.
+
+.SS History Expansion
+
+These functions implement history expansion.
+
+.Fn2 int history_expand "char *string" "char **output"
+Expand \fIstring\fP, placing the result into \fIoutput\fP, a pointer
+to a string. Returns:
+.RS
+.PD 0
+.TP
+0
+If no expansions took place (or, if the only change in
+the text was the removal of escape characters preceding the history expansion
+character);
+.TP
+1
+if expansions did take place;
+.TP
+-1
+if there was an error in expansion;
+.TP
+2
+if the returned line should be displayed, but not executed,
+as with the \fB:p\fP modifier.
+.PD
+.RE
+If an error occurred in expansion, then \fIoutput\fP contains a descriptive
+error message.
+
+.Fn3 "char *" get_history_event "const char *string" "int *cindex" "int qchar"
+Returns the text of the history event beginning at \fIstring\fP +
+\fI*cindex\fP. \fI*cindex\fP is modified to point to after the event
+specifier. At function entry, \fIcindex\fP points to the index into
+\fIstring\fP where the history event specification begins. \fIqchar\fP
+is a character that is allowed to end the event specification in addition
+to the ``normal'' terminating characters.
+
+.Fn1 "char **" history_tokenize "const char *string"
+Return an array of tokens parsed out of \fIstring\fP, much as the
+shell might.
+The tokens are split on the characters in the
+\fBhistory_word_delimiters\fP variable,
+and shell quoting conventions are obeyed.
+
+.Fn3 "char *" history_arg_extract "int first" "int last" "const char *string"
+Extract a string segment consisting of the \fIfirst\fP through \fIlast\fP
+arguments present in \fIstring\fP. Arguments are split using
+\fBhistory_tokenize()\fP.
+
+.SS History Variables
+
+This section describes the externally-visible variables exported by
+the GNU History Library.
+
+.Vb int history_base
+The logical offset of the first entry in the history list.
+
+.Vb int history_length
+The number of entries currently stored in the history list.
+
+.Vb int history_max_entries
+The maximum number of history entries. This must be changed using
+\fBstifle_history()\fP.
+
+.Vb int history_write_timestamps
+If non-zero, timestamps are written to the history file, so they can be
+preserved between sessions. The default value is 0, meaning that
+timestamps are not saved.
+The current timestamp format uses the value of \fIhistory_comment_char\fP
+to delimit timestamp entries in the history file. If that variable does
+not have a value (the default), timestamps will not be written.
+
+.Vb char history_expansion_char
+The character that introduces a history event. The default is \fB!\fP.
+Setting this to 0 inhibits history expansion.
+
+.Vb char history_subst_char
+The character that invokes word substitution if found at the start of
+a line. The default is \fB^\fP.
+
+.Vb char history_comment_char
+During tokenization, if this character is seen as the first character
+of a word, then it and all subsequent characters up to a newline are
+ignored, suppressing history expansion for the remainder of the line.
+This is disabled by default.
+
+.Vb "char *" history_word_delimiters
+The characters that separate tokens for \fBhistory_tokenize()\fP.
+The default value is \fB"\ \et\en()<>;&|"\fP.
+
+.Vb "char *" history_no_expand_chars
+The list of characters which inhibit history expansion if found immediately
+following \fBhistory_expansion_char\fP. The default is space, tab, newline,
+\fB\er\fP, and \fB=\fP.
+
+.Vb "char *" history_search_delimiter_chars
+The list of additional characters which can delimit a history search
+string, in addition to space, tab, \fI:\fP and \fI?\fP in the case of
+a substring search. The default is empty.
+
+.Vb int history_quotes_inhibit_expansion
+If non-zero, double-quoted words are not scanned for the history expansion
+character or the history comment character. The default value is 0.
+
+.Vb "rl_linebuf_func_t *" history_inhibit_expansion_function
+This should be set to the address of a function that takes two arguments:
+a \fBchar *\fP (\fIstring\fP)
+and an \fBint\fP index into that string (\fIi\fP).
+It should return a non-zero value if the history expansion starting at
+\fIstringi\fP should not be performed; zero if the expansion should
+be done.
+It is intended for use by applications like \fBbash\fP that use the history
+expansion character for additional purposes.
+By default, this variable is set to \fBNULL\fP.

+<H2> 1.1 History Expansion </H2>
+
+
+
+The History library provides a history expansion feature that is similar
+to the history expansion provided by <CODE>csh</CODE>. This section
+describes the syntax used to manipulate the history information.
+
+
+History expansions introduce words from the history list into
+the input stream, making it easy to repeat commands, insert the
+arguments to a previous command into the current input line, or
+fix errors in previous commands quickly.
+
+
+History expansion takes place in two parts. The first is to determine
+which line from the history list should be used during substitution.
+The second is to select portions of that line for inclusion into the
+current one. The line selected from the history is called the
+event, and the portions of that line that are acted upon are
+called words. Various modifiers are available to manipulate
+the selected words. The line is broken into words in the same fashion
+that Bash does, so that several words
+surrounded by quotes are considered one word.
+History expansions are introduced by the appearance of the
+history expansion character, which is <SAMP>`!'</SAMP> by default.
+
+
+History expansion implements shell-like quoting conventions:
+a backslash can be used to remove the special handling for the next character;
+single quotes enclose verbatim sequences of characters, and can be used to
+inhibit history expansion;
+and characters enclosed within double quotes may be subject to history
+expansion, since backslash can escape the history expansion character,
+but single quotes may not, since they are not treated specially within
+double quotes.

+<H3> 1.1.2 Word Designators </H3>
+
+
+
+Word designators are used to select desired words from the event.
+A <SAMP>`:'</SAMP> separates the event specification from the word designator. It
+may be omitted if the word designator begins with a <SAMP>`^'</SAMP>, <SAMP>`$'</SAMP>,
+<SAMP>`*'</SAMP>, <SAMP>`-'</SAMP>, or <SAMP>`%'</SAMP>. Words are numbered from the beginning
+of the line, with the first word being denoted by 0 (zero). Words are
+inserted into the current line separated by single spaces.
+
+
+For example,
+
+
+<DL COMPACT>
+<DT><CODE>!!</CODE>
+<DD>designates the preceding command. When you type this, the preceding
+command is repeated in toto.
+
+
+<DT><CODE>!!:$</CODE>
+<DD>designates the last argument of the preceding command. This may be
+shortened to <CODE>!$</CODE>.
+
+
+<DT><CODE>!fi:2</CODE>
+<DD>designates the second argument of the most recent command starting with
+the letters <CODE>fi</CODE>.
+</DL>
+
+
+Here are the word designators:
+ 
+<DL COMPACT>
+
+<DT><CODE>0 (zero)</CODE>
+<DD>The <CODE>0</CODE>th word. For many applications, this is the command word.
+
+
+<DT><CODE><VAR>n</VAR></CODE>
+<DD>The <VAR>n</VAR>th word.
+
+
+<DT><CODE>^</CODE>
+<DD>The first argument; that is, word 1.
+
+
+<DT><CODE>$</CODE>
+<DD>The last argument.
+
+
+<DT><CODE>%</CODE>
+<DD>The first word matched by the most recent <SAMP>`?<VAR>string</VAR>?'</SAMP> search,
+if the search string begins with a character that is part of a word.
+
+
+<DT><CODE><VAR>x</VAR>-<VAR>y</VAR></CODE>
+<DD>A range of words; <SAMP>`-<VAR>y</VAR>'</SAMP> abbreviates <SAMP>`0-<VAR>y</VAR>'</SAMP>.
+
+
+<DT><CODE>*</CODE>
+<DD>All of the words, except the <CODE>0</CODE>th. This is a synonym for <SAMP>`1-$'</SAMP>.
+It is not an error to use <SAMP>`*'</SAMP> if there is just one word in the event;
+the empty string is returned in that case.
+
+
+<DT><CODE><VAR>x</VAR>*</CODE>
+<DD>Abbreviates <SAMP>`<VAR>x</VAR>-$'</SAMP>
+
+
+<DT><CODE><VAR>x</VAR>-</CODE>
+<DD>Abbreviates <SAMP>`<VAR>x</VAR>-$'</SAMP> like <SAMP>`<VAR>x</VAR>*'</SAMP>, but omits the last word.
+If <SAMP>`x'</SAMP> is missing, it defaults to 0.
+
+
+</DL>
+
+
+If a word designator is supplied without an event specification, the
+previous command is used as the event.

+event line.
+Any character may be used as the delimiter in place of <SAMP>`/'</SAMP>.
+The delimiter may be quoted in <VAR>old</VAR> and <VAR>new</VAR>
+with a single backslash. If <SAMP>`&#38;'</SAMP> appears in <VAR>new</VAR>,
+it is replaced by <VAR>old</VAR>. A single backslash will quote
+the <SAMP>`&#38;'</SAMP>.
+If <VAR>old</VAR> is null, it is set to the last <VAR>old</VAR>
+substituted, or, if no previous history substitutions took place,
+the last <VAR>string</VAR>
+in a !?<VAR>string</VAR><CODE>?</CODE>
+search.
+If <VAR>new</VAR> is is null, each matching <VAR>old</VAR> is deleted.
+The final delimiter is optional if it is the last
+character on the input line.
+
+
+<DT><CODE>&#38;</CODE>
+<DD>Repeat the previous substitution.

+<H2> 2.1 Introduction to History </H2>
+
+
+
+Many programs read input from the user a line at a time. The GNU
+History library is able to keep track of those lines, associate arbitrary
+data with each line, and utilize information from previous lines in
+composing new ones. 
+
+
+A programmer using the History library has available functions
+for remembering lines on a history list, associating arbitrary data
+with a line, removing lines from the list, searching through the list
+for a line containing an arbitrary text string, and referencing any line
+in the list directly. In addition, a history expansion function
+is available which provides for a consistent user interface across
+different programs.
+
+
+The user using programs written with the History library has the
+benefit of a consistent user interface with a set of well-known
+commands for manipulating the text of previous lines and using that text
+in new commands. The basic history manipulation commands are similar to
+the history substitution provided by <CODE>csh</CODE>.
+
+
+The programmer can also use the Readline library, which
+includes some history manipulation by default, and has the added
+advantage of command line editing.
+
+
+Before declaring any functions using any functionality the History
+library provides in other code, an application writer should include
+the file <CODE>&#60;readline/history.h&#62;</CODE> in any file that uses the
+History library's features. It supplies extern declarations for all
+of the library's public functions and variables, and declares all of
+the public data structures.

+<H2> 2.2 History Storage </H2>
+
+
+
+The history list is an array of history entries. A history entry is
+declared as follows:
+
+
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>typedef void *histdata_t;
+
+typedef struct _hist_entry {
+ char *line;
+ char *timestamp;
+ histdata_t data;
+} HIST_ENTRY;
+</pre></td></tr></table>
+
+The history list itself might therefore be declared as
+
+
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>HIST_ENTRY **the_history_list;
+</pre></td></tr></table>
+
+The state of the History library is encapsulated into a single structure:
+
+
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>/*
+ * A structure used to pass around the current state of the history.
+ */
+typedef struct _hist_state {
+ HIST_ENTRY **entries; /* Pointer to the entries themselves. */
+ int offset; /* The location pointer within this array. */
+ int length; /* Number of elements within this array. */
+ int size; /* Number of slots allocated to this array. */
+ int flags;
+} HISTORY_STATE;
+</pre></td></tr></table>
+
+If the flags member includes <CODE>HS_STIFLED</CODE>, the history has been
+stifled.

+<H3> 2.3.6 Managing the History File </H3>
+
+
+
+The History library can read the history from and write it to a file.
+This section documents the functions for managing a history file.
+
+
+<A NAME="IDX27"></A>
+<DL>
+<DT>Function: int read_history (const char *filename)
+<DD>Add the contents of <VAR>filename</VAR> to the history list, a line at a time.
+If <VAR>filename</VAR> is <CODE>NULL</CODE>, then read from <TT>`~/.history'</TT>.
+Returns 0 if successful, or <CODE>errno</CODE> if not.
+</DL>
+
+
+<A NAME="IDX28"></A>
+<DL>
+<DT>Function: int read_history_range (const char *filename, int from, int to)
+<DD>Read a range of lines from <VAR>filename</VAR>, adding them to the history list.
+Start reading at line <VAR>from</VAR> and end at <VAR>to</VAR>.
+If <VAR>from</VAR> is zero, start at the beginning. If <VAR>to</VAR> is less than
+<VAR>from</VAR>, then read until the end of the file. If <VAR>filename</VAR> is
+<CODE>NULL</CODE>, then read from <TT>`~/.history'</TT>. Returns 0 if successful,
+or <CODE>errno</CODE> if not.
+</DL>
+
+
+<A NAME="IDX29"></A>
+<DL>
+<DT>Function: int write_history (const char *filename)
+<DD>Write the current history to <VAR>filename</VAR>, overwriting <VAR>filename</VAR>
+if necessary.
+If <VAR>filename</VAR> is <CODE>NULL</CODE>, then write the history list to
+<TT>`~/.history'</TT>.
+Returns 0 on success, or <CODE>errno</CODE> on a read or write error.
+</DL>
+
+
+<A NAME="IDX30"></A>
+<DL>
+<DT>Function: int append_history (int nelements, const char *filename)
+<DD>Append the last <VAR>nelements</VAR> of the history list to <VAR>filename</VAR>.
+If <VAR>filename</VAR> is <CODE>NULL</CODE>, then append to <TT>`~/.history'</TT>.
+Returns 0 on success, or <CODE>errno</CODE> on a read or write error.
+</DL>
+
+
+<A NAME="IDX31"></A>
+<DL>
+<DT>Function: int history_truncate_file (const char *filename, int nlines)
+<DD>Truncate the history file <VAR>filename</VAR>, leaving only the last
+<VAR>nlines</VAR> lines.
+If <VAR>filename</VAR> is <CODE>NULL</CODE>, then <TT>`~/.history'</TT> is truncated.
+Returns 0 on success, or <CODE>errno</CODE> on failure.

+
+
+
+These functions implement history expansion.
+
+
+<A NAME="IDX32"></A>
+<DL>
+<DT>Function: int history_expand (char *string, char **output)
+<DD>Expand <VAR>string</VAR>, placing the result into <VAR>output</VAR>, a pointer
+to a string (see section <A HREF="history.html#SEC2">1.1 History Expansion</A>). Returns:
+<DL COMPACT>
+<DT><CODE>0</CODE>
+<DD>If no expansions took place (or, if the only change in
+the text was the removal of escape characters preceding the history expansion
+character);
+<DT><CODE>1</CODE>
+<DD>if expansions did take place;
+<DT><CODE>-1</CODE>
+<DD>if there was an error in expansion;
+<DT><CODE>2</CODE>
+<DD>if the returned line should be displayed, but not executed,
+as with the <CODE>:p</CODE> modifier (see section <A HREF="history.html#SEC5">1.1.3 Modifiers</A>).
+</DL>
+
+
+If an error occurred in expansion, then <VAR>output</VAR> contains a descriptive
+error message.

+<A NAME="IDX33"></A>
+<DL>
+<DT>Function: char * get_history_event (const char *string, int *cindex, int qchar)
+<DD>Returns the text of the history event beginning at <VAR>string</VAR> +
+<VAR>*cindex</VAR>. <VAR>*cindex</VAR> is modified to point to after the event
+specifier. At function entry, <VAR>cindex</VAR> points to the index into
+<VAR>string</VAR> where the history event specification begins. <VAR>qchar</VAR>
+is a character that is allowed to end the event specification in addition
+to the "normal" terminating characters.
+</DL>
+
+
+<A NAME="IDX34"></A>
+<DL>
+<DT>Function: char ** history_tokenize (const char *string)
+<DD>Return an array of tokens parsed out of <VAR>string</VAR>, much as the
+shell might. The tokens are split on the characters in the
+<VAR>history_word_delimiters</VAR> variable,
+and shell quoting conventions are obeyed as described below.
+</DL>
+
+
+<A NAME="IDX35"></A>
+<DL>
+<DT>Function: char * history_arg_extract (int first, int last, const char *string)
+<DD>Extract a string segment consisting of the <VAR>first</VAR> through <VAR>last</VAR>
+arguments present in <VAR>string</VAR>. Arguments are split using
+<CODE>history_tokenize</CODE>.

+<H2> 2.4 History Variables </H2>
+
+
+
+This section describes the externally-visible variables exported by
+the GNU History Library.
+
+
+<A NAME="IDX36"></A>
+<DL>
+<DT>Variable: int history_base
+<DD>The logical offset of the first entry in the history list.
+</DL>
+
+
+<A NAME="IDX37"></A>
+<DL>
+<DT>Variable: int history_length
+<DD>The number of entries currently stored in the history list.
+</DL>
+
+
+<A NAME="IDX38"></A>
+<DL>
+<DT>Variable: int history_max_entries
+<DD>The maximum number of history entries. This must be changed using
+<CODE>stifle_history()</CODE>.
+</DL>
+
+
+<A NAME="IDX39"></A>
+<DL>
+<DT>Variable: int history_write_timestamps
+<DD>If non-zero, timestamps are written to the history file, so they can be
+preserved between sessions. The default value is 0, meaning that
+timestamps are not saved.
+
+
+The current timestamp format uses the value of <VAR>history_comment_char</VAR>
+to delimit timestamp entries in the history file. If that variable does
+not have a value (the default), timestamps will not be written.
+</DL>
+
+
+<A NAME="IDX40"></A>
+<DL>
+<DT>Variable: char history_expansion_char
+<DD>The character that introduces a history event. The default is <SAMP>`!'</SAMP>.
+Setting this to 0 inhibits history expansion.
+</DL>
+
+
+<A NAME="IDX41"></A>
+<DL>
+<DT>Variable: char history_subst_char
+<DD>The character that invokes word substitution if found at the start of
+a line. The default is <SAMP>`^'</SAMP>.
+</DL>
+
+
+<A NAME="IDX42"></A>
+<DL>
+<DT>Variable: char history_comment_char
+<DD>During tokenization, if this character is seen as the first character
+of a word, then it and all subsequent characters up to a newline are
+ignored, suppressing history expansion for the remainder of the line.
+This is disabled by default.
+</DL>
+
+
+<A NAME="IDX43"></A>
+<DL>
+<DT>Variable: char * history_word_delimiters
+<DD>The characters that separate tokens for <CODE>history_tokenize()</CODE>.
+The default value is <CODE>" \t\n()<>;&|"</CODE>.
+</DL>
+
+
+<A NAME="IDX44"></A>
+<DL>
+<DT>Variable: char * history_search_delimiter_chars
+<DD>The list of additional characters which can delimit a history search
+string, in addition to space, TAB, <SAMP>`:'</SAMP> and <SAMP>`?'</SAMP> in the case of
+a substring search. The default is empty.
+</DL>
+
+
+<A NAME="IDX45"></A>
+<DL>
+<DT>Variable: char * history_no_expand_chars
+<DD>The list of characters which inhibit history expansion if found immediately
+following <VAR>history_expansion_char</VAR>. The default is space, tab, newline,
+carriage return, and <SAMP>`='</SAMP>.
+</DL>
+
+
+<A NAME="IDX46"></A>
+<DL>
+<DT>Variable: int history_quotes_inhibit_expansion
+<DD>If non-zero, the history expansion code implements shell-like quoting:
+single-quoted words are not scanned for the history expansion
+character or the history comment character, and double-quoted words may
+have history expansion performed, since single quotes are not special
+within double quotes.
+The default value is 0.
+</DL>
+
+
+<A NAME="IDX47"></A>
+<DL>
+<DT>Variable: int history_quoting_state
+<DD>An application may set this variable to indicate that the current line
+being expanded is subject to existing quoting. If set to <SAMP>`''</SAMP>, the
+history expansion function will assume that the line is single-quoted and
+inhibit expansion until it reads an unquoted closing single quote; if set
+to <SAMP>`"'</SAMP>, history expansion will assume the line is double quoted until
+it reads an unquoted closing double quote. If set to zero, the default,
+the history expansion function will assume the line is not quoted and
+treat quote characters within the line as described above.
+This is only effective if <VAR>history_quotes_inhibit_expansion</VAR> is set.
+</DL>
+
+
+<A NAME="IDX48"></A>
+<DL>
+<DT>Variable: rl_linebuf_func_t * history_inhibit_expansion_function
+<DD>This should be set to the address of a function that takes two arguments:
+a <CODE>char *</CODE> (<VAR>string</VAR>)
+and an <CODE>int</CODE> index into that string (<VAR>i</VAR>).
+It should return a non-zero value if the history expansion starting at
+<VAR>stringi</VAR> should not be performed; zero if the expansion should
+be done.
+It is intended for use by applications like Bash that use the history
+expansion character for additional purposes.
+By default, this variable is set to <CODE>NULL</CODE>.

+PREAMBLE
+
+
+The purpose of this License is to make a manual, textbook, or other
+functional and useful document free in the sense of freedom: to
+assure everyone the effective freedom to copy and redistribute it,
+with or without modifying it, either commercially or noncommercially.
+Secondarily, this License preserves for the author and publisher a way
+to get credit for their work, while not being considered responsible
+for modifications made by others.
+
+
+This License is a kind of "copyleft", which means that derivative
+works of the document must themselves be free in the same sense. It
+complements the GNU General Public License, which is a copyleft
+license designed for free software.
+
+
+We have designed this License in order to use it for manuals for free
+software, because free software needs free documentation: a free
+program should come with manuals providing the same freedoms that the
+software does. But this License is not limited to software manuals;
+it can be used for any textual work, regardless of subject matter or
+whether it is published as a printed book. We recommend this License
+principally for works whose purpose is instruction or reference.
+
+
+<LI>
+APPLICABILITY AND DEFINITIONS
+
+
+This License applies to any manual or other work, in any medium, that
+contains a notice placed by the copyright holder saying it can be
+distributed under the terms of this License. Such a notice grants a
+world-wide, royalty-free license, unlimited in duration, to use that
+work under the conditions stated herein. The "Document", below,
+refers to any such manual or work. Any member of the public is a
+licensee, and is addressed as "you". You accept the license if you
+copy, modify or distribute the work in a way requiring permission
+under copyright law.
+
+
+A "Modified Version" of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with
+modifications and/or translated into another language.
+
+
+A "Secondary Section" is a named appendix or a front-matter section
+of the Document that deals exclusively with the relationship of the
+publishers or authors of the Document to the Document's overall
+subject (or to related matters) and contains nothing that could fall
+directly within that overall subject. (Thus, if the Document is in
+part a textbook of mathematics, a Secondary Section may not explain
+any mathematics.) The relationship could be a matter of historical
+connection with the subject or with related matters, or of legal,
+commercial, philosophical, ethical or political position regarding
+them.
+
+
+The "Invariant Sections" are certain Secondary Sections whose titles
+are designated, as being those of Invariant Sections, in the notice
+that says that the Document is released under this License. If a
+section does not fit the above definition of Secondary then it is not
+allowed to be designated as Invariant. The Document may contain zero
+Invariant Sections. If the Document does not identify any Invariant
+Sections then there are none.
+
+
+The "Cover Texts" are certain short passages of text that are listed,
+as Front-Cover Texts or Back-Cover Texts, in the notice that says that
+the Document is released under this License. A Front-Cover Text may
+be at most 5 words, and a Back-Cover Text may be at most 25 words.
+
+
+A "Transparent" copy of the Document means a machine-readable copy,
+represented in a format whose specification is available to the
+general public, that is suitable for revising the document
+straightforwardly with generic text editors or (for images composed of
+pixels) generic paint programs or (for drawings) some widely available
+drawing editor, and that is suitable for input to text formatters or
+for automatic translation to a variety of formats suitable for input
+to text formatters. A copy made in an otherwise Transparent file
+format whose markup, or absence of markup, has been arranged to thwart
+or discourage subsequent modification by readers is not Transparent.
+An image format is not Transparent if used for any substantial amount
+of text. A copy that is not "Transparent" is called "Opaque".
+
+
+Examples of suitable formats for Transparent copies include plain
+ASCII without markup, Texinfo input format, LaTeX input
+format, SGML or XML using a publicly available
+DTD, and standard-conforming simple HTML,
+PostScript or PDF designed for human modification. Examples
+of transparent image formats include PNG, XCF and
+JPG. Opaque formats include proprietary formats that can be
+read and edited only by proprietary word processors, SGML or
+XML for which the DTD and/or processing tools are
+not generally available, and the machine-generated HTML,
+PostScript or PDF produced by some word processors for
+output purposes only.
+
+
+The "Title Page" means, for a printed book, the title page itself,
+plus such following pages as are needed to hold, legibly, the material
+this License requires to appear in the title page. For works in
+formats which do not have any title page as such, "Title Page" means
+the text near the most prominent appearance of the work's title,
+preceding the beginning of the body of the text.
+
+
+The "publisher" means any person or entity that distributes copies
+of the Document to the public.
+
+
+A section "Entitled XYZ" means a named subunit of the Document whose
+title either is precisely XYZ or contains XYZ in parentheses following
+text that translates XYZ in another language. (Here XYZ stands for a
+specific section name mentioned below, such as "Acknowledgements",
+"Dedications", "Endorsements", or "History".) To "Preserve the Title"
+of such a section when you modify the Document means that it remains a
+section "Entitled XYZ" according to this definition.
+
+
+The Document may include Warranty Disclaimers next to the notice which
+states that this License applies to the Document. These Warranty
+Disclaimers are considered to be included by reference in this
+License, but only as regards disclaiming warranties: any other
+implication that these Warranty Disclaimers may have is void and has
+no effect on the meaning of this License.
+
+
+<LI>
+VERBATIM COPYING
+
+
+You may copy and distribute the Document in any medium, either
+commercially or noncommercially, provided that this License, the
+copyright notices, and the license notice saying this License applies
+to the Document are reproduced in all copies, and that you add no other
+conditions whatsoever to those of this License. You may not use
+technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute. However, you may accept
+compensation in exchange for copies. If you distribute a large enough
+number of copies you must also follow the conditions in section 3.
+
+
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+
+
+<LI>
+COPYING IN QUANTITY
+
+
+If you publish printed copies (or copies in media that commonly have
+printed covers) of the Document, numbering more than 100, and the
+Document's license notice requires Cover Texts, you must enclose the
+copies in covers that carry, clearly and legibly, all these Cover
+Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
+the back cover. Both covers must also clearly and legibly identify
+you as the publisher of these copies. The front cover must present
+the full title with all words of the title equally prominent and
+visible. You may add other material on the covers in addition.
+Copying with changes limited to the covers, as long as they preserve
+the title of the Document and satisfy these conditions, can be treated
+as verbatim copying in other respects.
+
+
+If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+
+
+If you publish or distribute Opaque copies of the Document numbering
+more than 100, you must either include a machine-readable Transparent
+copy along with each Opaque copy, or state in or with each Opaque copy
+a computer-network location from which the general network-using
+public has access to download using public-standard network protocols
+a complete Transparent copy of the Document, free of added material.
+If you use the latter option, you must take reasonably prudent steps,
+when you begin distribution of Opaque copies in quantity, to ensure
+that this Transparent copy will remain thus accessible at the stated
+location until at least one year after the last time you distribute an
+Opaque copy (directly or through your agents or retailers) of that
+edition to the public.
+
+
+It is requested, but not required, that you contact the authors of the
+Document well before redistributing any large number of copies, to give
+them a chance to provide you with an updated version of the Document.
+
+
+<LI>
+MODIFICATIONS
+
+
+You may copy and distribute a Modified Version of the Document under
+the conditions of sections 2 and 3 above, provided that you release
+the Modified Version under precisely this License, with the Modified
+Version filling the role of the Document, thus licensing distribution
+and modification of the Modified Version to whoever possesses a copy
+of it. In addition, you must do these things in the Modified Version:
+
+
+<OL>
+<LI>
+Use in the Title Page (and on the covers, if any) a title distinct
+from that of the Document, and from those of previous versions
+(which should, if there were any, be listed in the History section
+of the Document). You may use the same title as a previous version
+if the original publisher of that version gives permission.
+
+
+<LI>
+List on the Title Page, as authors, one or more persons or entities
+responsible for authorship of the modifications in the Modified
+Version, together with at least five of the principal authors of the
+Document (all of its principal authors, if it has fewer than five),
+unless they release you from this requirement.
+
+
+<LI>
+State on the Title page the name of the publisher of the
+Modified Version, as the publisher.
+
+
+<LI>
+Preserve all the copyright notices of the Document.
+
+
+<LI>
+Add an appropriate copyright notice for your modifications
+adjacent to the other copyright notices.
+
+
+<LI>
+Include, immediately after the copyright notices, a license notice
+giving the public permission to use the Modified Version under the
+terms of this License, in the form shown in the Addendum below.
+
+
+<LI>
+Preserve in that license notice the full lists of Invariant Sections
+and required Cover Texts given in the Document's license notice.
+
+
+<LI>
+Include an unaltered copy of this License.
+
+
+<LI>
+Preserve the section Entitled "History", Preserve its Title, and add
+to it an item stating at least the title, year, new authors, and
+publisher of the Modified Version as given on the Title Page. If
+there is no section Entitled "History" in the Document, create one
+stating the title, year, authors, and publisher of the Document as
+given on its Title Page, then add an item describing the Modified
+Version as stated in the previous sentence.
+
+
+<LI>
+Preserve the network location, if any, given in the Document for
+public access to a Transparent copy of the Document, and likewise
+the network locations given in the Document for previous versions
+it was based on. These may be placed in the "History" section.
+You may omit a network location for a work that was published at
+least four years before the Document itself, or if the original
+publisher of the version it refers to gives permission.
+
+
+<LI>
+For any section Entitled "Acknowledgements" or "Dedications", Preserve
+the Title of the section, and preserve in the section all the
+substance and tone of each of the contributor acknowledgements and/or
+dedications given therein.
+
+
+<LI>
+Preserve all the Invariant Sections of the Document,
+unaltered in their text and in their titles. Section numbers
+or the equivalent are not considered part of the section titles.
+
+
+<LI>
+Delete any section Entitled "Endorsements". Such a section
+may not be included in the Modified Version.
+
+
+<LI>
+Do not retitle any existing section to be Entitled "Endorsements" or
+to conflict in title with any Invariant Section.
+
+
+<LI>
+Preserve any Warranty Disclaimers.
+</OL>
+
+
+If the Modified Version includes new front-matter sections or
+appendices that qualify as Secondary Sections and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant. To do this, add their titles to the
+list of Invariant Sections in the Modified Version's license notice.
+These titles must be distinct from any other section titles.
+
+
+You may add a section Entitled "Endorsements", provided it contains
+nothing but endorsements of your Modified Version by various
+parties--for example, statements of peer review or that the text has
+been approved by an organization as the authoritative definition of a
+standard.
+
+
+You may add a passage of up to five words as a Front-Cover Text, and a
+passage of up to 25 words as a Back-Cover Text, to the end of the list
+of Cover Texts in the Modified Version. Only one passage of
+Front-Cover Text and one of Back-Cover Text may be added by (or
+through arrangements made by) any one entity. If the Document already
+includes a cover text for the same cover, previously added by you or
+by arrangement made by the same entity you are acting on behalf of,
+you may not add another; but you may replace the old one, on explicit
+permission from the previous publisher that added the old one.
+
+
+The author(s) and publisher(s) of the Document do not by this License
+give permission to use their names for publicity for or to assert or
+imply endorsement of any Modified Version.
+
+
+<LI>
+COMBINING DOCUMENTS
+
+
+You may combine the Document with other documents released under this
+License, under the terms defined in section 4 above for modified
+versions, provided that you include in the combination all of the
+Invariant Sections of all of the original documents, unmodified, and
+list them all as Invariant Sections of your combined work in its
+license notice, and that you preserve all their Warranty Disclaimers.
+
+
+The combined work need only contain one copy of this License, and
+multiple identical Invariant Sections may be replaced with a single
+copy. If there are multiple Invariant Sections with the same name but
+different contents, make the title of each such section unique by
+adding at the end of it, in parentheses, the name of the original
+author or publisher of that section if known, or else a unique number.
+Make the same adjustment to the section titles in the list of
+Invariant Sections in the license notice of the combined work.
+
+
+In the combination, you must combine any sections Entitled "History"
+in the various original documents, forming one section Entitled
+"History"; likewise combine any sections Entitled "Acknowledgements",
+and any sections Entitled "Dedications". You must delete all
+sections Entitled "Endorsements."
+
+
+<LI>
+COLLECTIONS OF DOCUMENTS
+
+
+You may make a collection consisting of the Document and other documents
+released under this License, and replace the individual copies of this
+License in the various documents with a single copy that is included in
+the collection, provided that you follow the rules of this License for
+verbatim copying of each of the documents in all other respects.
+
+
+You may extract a single document from such a collection, and distribute
+it individually under this License, provided you insert a copy of this
+License into the extracted document, and follow this License in all
+other respects regarding verbatim copying of that document.
+
+
+<LI>
+AGGREGATION WITH INDEPENDENT WORKS
+
+
+A compilation of the Document or its derivatives with other separate
+and independent documents or works, in or on a volume of a storage or
+distribution medium, is called an "aggregate" if the copyright
+resulting from the compilation is not used to limit the legal rights
+of the compilation's users beyond what the individual works permit.
+When the Document is included in an aggregate, this License does not
+apply to the other works in the aggregate which are not themselves
+derivative works of the Document.
+
+
+If the Cover Text requirement of section 3 is applicable to these
+copies of the Document, then if the Document is less than one half of
+the entire aggregate, the Document's Cover Texts may be placed on
+covers that bracket the Document within the aggregate, or the
+electronic equivalent of covers if the Document is in electronic form.
+Otherwise they must appear on printed covers that bracket the whole
+aggregate.
+
+
+<LI>
+TRANSLATION
+
+
+Translation is considered a kind of modification, so you may
+distribute translations of the Document under the terms of section 4.
+Replacing Invariant Sections with translations requires special
+permission from their copyright holders, but you may include
+translations of some or all Invariant Sections in addition to the
+original versions of these Invariant Sections. You may include a
+translation of this License, and all the license notices in the
+Document, and any Warranty Disclaimers, provided that you also include
+the original English version of this License and the original versions
+of those notices and disclaimers. In case of a disagreement between
+the translation and the original version of this License or a notice
+or disclaimer, the original version will prevail.
+
+
+If a section in the Document is Entitled "Acknowledgements",
+"Dedications", or "History", the requirement (section 4) to Preserve
+its Title (section 1) will typically require changing the actual
+title.
+
+
+<LI>
+TERMINATION
+
+
+You may not copy, modify, sublicense, or distribute the Document
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense, or distribute it is void, and
+will automatically terminate your rights under this License.
+
+
+However, if you cease all violation of this License, then your license
+from a particular copyright holder is reinstated (a) provisionally,
+unless and until the copyright holder explicitly and finally
+terminates your license, and (b) permanently, if the copyright holder
+fails to notify you of the violation by some reasonable means prior to
+60 days after the cessation.
+
+
+Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+
+Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License. If your rights have been terminated and not permanently
+reinstated, receipt of a copy of some or all of the same material does
+not give you any rights to use it.
+
+
+<LI>
+FUTURE REVISIONS OF THIS LICENSE
+
+
+The Free Software Foundation may publish new, revised versions
+of the GNU Free Documentation License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns. See
+<A HREF="http://www.gnu.org/copyleft/">http://www.gnu.org/copyleft/</A>.
+
+
+Each version of the License is given a distinguishing version number.
+If the Document specifies that a particular numbered version of this
+License "or any later version" applies to it, you have the option of
+following the terms and conditions either of that specified version or
+of any later version that has been published (not as a draft) by the
+Free Software Foundation. If the Document does not specify a version
+number of this License, you may choose any version ever published (not
+as a draft) by the Free Software Foundation. If the Document
+specifies that a proxy can decide which future versions of this
+License can be used, that proxy's public statement of acceptance of a
+version permanently authorizes you to choose that version for the
+Document.
+
+
+<LI>
+RELICENSING
+
+
+"Massive Multiauthor Collaboration Site" (or "MMC Site") means any
+World Wide Web server that publishes copyrightable works and also
+provides prominent facilities for anybody to edit those works. A
+public wiki that anybody can edit is an example of such a server. A
+"Massive Multiauthor Collaboration" (or "MMC") contained in the
+site means any set of copyrightable works thus published on the MMC
+site.
+
+
+"CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0
+license published by Creative Commons Corporation, a not-for-profit
+corporation with a principal place of business in San Francisco,
+California, as well as future copyleft versions of that license
+published by that same organization.
+
+
+"Incorporate" means to publish or republish a Document, in whole or
+in part, as part of another Document.
+
+
+An MMC is "eligible for relicensing" if it is licensed under this
+License, and if all works that were first published under this License
+somewhere other than this MMC, and subsequently incorporated in whole
+or in part into the MMC, (1) had no cover texts or invariant sections,
+and (2) were thus incorporated prior to November 1, 2008.
+
+
+The operator of an MMC Site may republish an MMC contained in the site
+under CC-BY-SA on the same site at any time before August 1, 2009,
+provided the MMC is eligible for relicensing.

+<H2> ADDENDUM: How to use this License for your documents </H2>
+
+
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and
+license notices just after the title page:
+
+
+<TABLE><tr><td>&nbsp;</td><td class=smallexample><pre> Copyright (C) <VAR>year</VAR> <VAR>your name</VAR>.
+ Permission is granted to copy, distribute and/or modify this document
+ under the terms of the GNU Free Documentation License, Version 1.3
+ or any later version published by the Free Software Foundation;
+ with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
+ Texts. A copy of the license is included in the section entitled ``GNU
+ Free Documentation License''.
+</pre></td></tr></table>
+
+If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
+replace the "with...Texts." line with this:
+
+
+<TABLE><tr><td>&nbsp;</td><td class=smallexample><pre> with the Invariant Sections being <VAR>list their titles</VAR>, with
+ the Front-Cover Texts being <VAR>list</VAR>, and with the Back-Cover Texts
+ being <VAR>list</VAR>.
+</pre></td></tr></table>
+
+If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+
+
+If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of
+free software license, such as the GNU General Public License,
+to permit their use in free software.

+
+1.1 History Expansion
+=====================
+
+The History library provides a history expansion feature that is similar
+to the history expansion provided by 'csh'. This section describes the
+syntax used to manipulate the history information.
+
+ History expansions introduce words from the history list into the
+input stream, making it easy to repeat commands, insert the arguments to
+a previous command into the current input line, or fix errors in
+previous commands quickly.
+
+ History expansion takes place in two parts. The first is to
+determine which line from the history list should be used during
+substitution. The second is to select portions of that line for
+inclusion into the current one. The line selected from the history is
+called the "event", and the portions of that line that are acted upon
+are called "words". Various "modifiers" are available to manipulate the
+selected words. The line is broken into words in the same fashion that
+Bash does, so that several words surrounded by quotes are considered one
+word. History expansions are introduced by the appearance of the
+history expansion character, which is '!' by default.
+
+ History expansion implements shell-like quoting conventions: a
+backslash can be used to remove the special handling for the next
+character; single quotes enclose verbatim sequences of characters, and
+can be used to inhibit history expansion; and characters enclosed within
+double quotes may be subject to history expansion, since backslash can
+escape the history expansion character, but single quotes may not, since
+they are not treated specially within double quotes.

+&#x1f;
+File: history.info, Node: Event Designators, Next: Word Designators, Up: History Interaction
+
+1.1.1 Event Designators
+-----------------------
+
+An event designator is a reference to a command line entry in the
+history list. Unless the reference is absolute, events are relative to
+the current position in the history list.
+
+'!'
+ Start a history substitution, except when followed by a space, tab,
+ the end of the line, or '='.
+
+'!N'
+ Refer to command line N.
+
+'!-N'
+ Refer to the command N lines back.
+
+'!!'
+ Refer to the previous command. This is a synonym for '!-1'.
+
+'!STRING'
+ Refer to the most recent command preceding the current position in
+ the history list starting with STRING.
+
+'!?STRING?'
+ Refer to the most recent command preceding the current position in
+ the history list containing STRING. The trailing '?' may be
+ omitted if the STRING is followed immediately by a newline. If
+ STRING is missing, the string from the most recent search is used;
+ it is an error if there is no previous search string.
+
+'^STRING1^STRING2^'
+ Quick Substitution. Repeat the last command, replacing STRING1
+ with STRING2. Equivalent to '!!:s^STRING1^STRING2^'.
+
+'!#'
+ The entire command line typed so far.
+
+&#x1f;
+File: history.info, Node: Word Designators, Next: Modifiers, Prev: Event Designators, Up: History Interaction
+
+1.1.2 Word Designators
+----------------------
+
+Word designators are used to select desired words from the event. A ':'
+separates the event specification from the word designator. It may be
+omitted if the word designator begins with a '^', '$', '*', '-', or '%'.
+Words are numbered from the beginning of the line, with the first word
+being denoted by 0 (zero). Words are inserted into the current line
+separated by single spaces.
+
+ For example,
+
+'!!'
+ designates the preceding command. When you type this, the
+ preceding command is repeated in toto.
+
+'!!:$'
+ designates the last argument of the preceding command. This may be
+ shortened to '!$'.
+
+'!fi:2'
+ designates the second argument of the most recent command starting
+ with the letters 'fi'.
+
+ Here are the word designators:
+
+'0 (zero)'
+ The '0'th word. For many applications, this is the command word.
+
+'N'
+ The Nth word.
+
+'^'
+ The first argument; that is, word 1.
+
+'$'
+ The last argument.
+
+'%'
+ The first word matched by the most recent '?STRING?' search, if the
+ search string begins with a character that is part of a word.
+
+'X-Y'
+ A range of words; '-Y' abbreviates '0-Y'.
+
+'*'
+ All of the words, except the '0'th. This is a synonym for '1-$'.
+ It is not an error to use '*' if there is just one word in the
+ event; the empty string is returned in that case.
+
+'X*'
+ Abbreviates 'X-$'
+
+'X-'
+ Abbreviates 'X-$' like 'X*', but omits the last word. If 'x' is
+ missing, it defaults to 0.
+
+ If a word designator is supplied without an event specification, the
+previous command is used as the event.
+
+&#x1f;
+File: history.info, Node: Modifiers, Prev: Word Designators, Up: History Interaction
+
+1.1.3 Modifiers
+---------------
+
+After the optional word designator, you can add a sequence of one or
+more of the following modifiers, each preceded by a ':'. These modify,
+or edit, the word or words selected from the history event.
+
+'h'
+ Remove a trailing pathname component, leaving only the head.
+
+'t'
+ Remove all leading pathname components, leaving the tail.
+
+'r'
+ Remove a trailing suffix of the form '.SUFFIX', leaving the
+ basename.
+
+'e'
+ Remove all but the trailing suffix.
+
+'p'
+ Print the new command but do not execute it.
+
+'s/OLD/NEW/'
+ Substitute NEW for the first occurrence of OLD in the event line.
+ Any character may be used as the delimiter in place of '/'. The
+ delimiter may be quoted in OLD and NEW with a single backslash. If
+ '&' appears in NEW, it is replaced by OLD. A single backslash will
+ quote the '&'. If OLD is null, it is set to the last OLD
+ substituted, or, if no previous history substitutions took place,
+ the last STRING in a !?STRING'?' search. If NEW is is null, each
+ matching OLD is deleted. The final delimiter is optional if it is
+ the last character on the input line.
+
+'&'
+ Repeat the previous substitution.
+
+'g'
+'a'
+ Cause changes to be applied over the entire event line. Used in
+ conjunction with 's', as in 'gs/OLD/NEW/', or with '&'.
+
+'G'
+ Apply the following 's' or '&' modifier once to each word in the
+ event.

+2.1 Introduction to History
+===========================
+
+Many programs read input from the user a line at a time. The GNU
+History library is able to keep track of those lines, associate
+arbitrary data with each line, and utilize information from previous
+lines in composing new ones.
+
+ A programmer using the History library has available functions for
+remembering lines on a history list, associating arbitrary data with a
+line, removing lines from the list, searching through the list for a
+line containing an arbitrary text string, and referencing any line in
+the list directly. In addition, a history "expansion" function is
+available which provides for a consistent user interface across
+different programs.
+
+ The user using programs written with the History library has the
+benefit of a consistent user interface with a set of well-known commands
+for manipulating the text of previous lines and using that text in new
+commands. The basic history manipulation commands are similar to the
+history substitution provided by 'csh'.
+
+ The programmer can also use the Readline library, which includes some
+history manipulation by default, and has the added advantage of command
+line editing.
+
+ Before declaring any functions using any functionality the History
+library provides in other code, an application writer should include the
+file '<readline/history.h>' in any file that uses the History library's
+features. It supplies extern declarations for all of the library's
+public functions and variables, and declares all of the public data
+structures.
+
+&#x1f;
+File: history.info, Node: History Storage, Next: History Functions, Prev: Introduction to History, Up: Programming with GNU History
+
+2.2 History Storage
+===================
+
+The history list is an array of history entries. A history entry is
+declared as follows:
+
+ typedef void *histdata_t;
+
+ typedef struct _hist_entry {
+ char *line;
+ char *timestamp;
+ histdata_t data;
+ } HIST_ENTRY;
+
+ The history list itself might therefore be declared as
+
+ HIST_ENTRY **the_history_list;
+
+ The state of the History library is encapsulated into a single
+structure:
+
+ /*
+ * A structure used to pass around the current state of the history.
+ */
+ typedef struct _hist_state {
+ HIST_ENTRY **entries; /* Pointer to the entries themselves. */
+ int offset; /* The location pointer within this array. */
+ int length; /* Number of elements within this array. */
+ int size; /* Number of slots allocated to this array. */
+ int flags;
+ } HISTORY_STATE;
+
+ If the flags member includes 'HS_STIFLED', the history has been
+stifled.

+2.3.1 Initializing History and State Management
+-----------------------------------------------
+
+This section describes functions used to initialize and manage the state
+of the History library when you want to use the history functions in
+your program.
+
+ -- Function: void using_history (void)
+ Begin a session in which the history functions might be used. This
+ initializes the interactive variables.
+
+ -- Function: HISTORY_STATE * history_get_history_state (void)
+ Return a structure describing the current state of the input
+ history.
+
+ -- Function: void history_set_history_state (HISTORY_STATE *state)
+ Set the state of the history list according to STATE.
+
+&#x1f;
+File: history.info, Node: History List Management, Next: Information About the History List, Prev: Initializing History and State Management, Up: History Functions
+
+2.3.2 History List Management
+-----------------------------
+
+These functions manage individual entries on the history list, or set
+parameters managing the list itself.
+
+ -- Function: void add_history (const char *string)
+ Place STRING at the end of the history list. The associated data
+ field (if any) is set to 'NULL'. If the maximum number of history
+ entries has been set using 'stifle_history()', and the new number
+ of history entries would exceed that maximum, the oldest history
+ entry is removed.
+
+ -- Function: void add_history_time (const char *string)
+ Change the time stamp associated with the most recent history entry
+ to STRING.
+
+ -- Function: HIST_ENTRY * remove_history (int which)
+ Remove history entry at offset WHICH from the history. The removed
+ element is returned so you can free the line, data, and containing
+ structure.
+
+ -- Function: histdata_t free_history_entry (HIST_ENTRY *histent)
+ Free the history entry HISTENT and any history library private data
+ associated with it. Returns the application-specific data so the
+ caller can dispose of it.
+
+ -- Function: HIST_ENTRY * replace_history_entry (int which, const char
+ *line, histdata_t data)
+ Make the history entry at offset WHICH have LINE and DATA. This
+ returns the old entry so the caller can dispose of any
+ application-specific data. In the case of an invalid WHICH, a
+ 'NULL' pointer is returned.
+
+ -- Function: void clear_history (void)
+ Clear the history list by deleting all the entries.
+
+ -- Function: void stifle_history (int max)
+ Stifle the history list, remembering only the last MAX entries.
+ The history list will contain only MAX entries at a time.
+
+ -- Function: int unstifle_history (void)
+ Stop stifling the history. This returns the previously-set maximum
+ number of history entries (as set by 'stifle_history()'). The
+ value is positive if the history was stifled, negative if it
+ wasn't.
+
+ -- Function: int history_is_stifled (void)
+ Returns non-zero if the history is stifled, zero if it is not.
+
+&#x1f;
+File: history.info, Node: Information About the History List, Next: Moving Around the History List, Prev: History List Management, Up: History Functions
+
+2.3.3 Information About the History List
+----------------------------------------
+
+These functions return information about the entire history list or
+individual list entries.
+
+ -- Function: HIST_ENTRY ** history_list (void)
+ Return a 'NULL' terminated array of 'HIST_ENTRY *' which is the
+ current input history. Element 0 of this list is the beginning of
+ time. If there is no history, return 'NULL'.
+
+ -- Function: int where_history (void)
+ Returns the offset of the current history element.
+
+ -- Function: HIST_ENTRY * current_history (void)
+ Return the history entry at the current position, as determined by
+ 'where_history()'. If there is no entry there, return a 'NULL'
+ pointer.
+
+ -- Function: HIST_ENTRY * history_get (int offset)
+ Return the history entry at position OFFSET. The range of valid
+ values of OFFSET starts at 'history_base' and ends at
+ HISTORY_LENGTH - 1 (*note History Variables::). If there is no
+ entry there, or if OFFSET is outside the valid range, return a
+ 'NULL' pointer.
+
+ -- Function: time_t history_get_time (HIST_ENTRY *entry)
+ Return the time stamp associated with the history entry ENTRY. If
+ the timestamp is missing or invalid, return 0.
+
+ -- Function: int history_total_bytes (void)
+ Return the number of bytes that the primary history entries are
+ using. This function returns the sum of the lengths of all the
+ lines in the history.
+
+&#x1f;
+File: history.info, Node: Moving Around the History List, Next: Searching the History List, Prev: Information About the History List, Up: History Functions
+
+2.3.4 Moving Around the History List
+------------------------------------
+
+These functions allow the current index into the history list to be set
+or changed.
+
+ -- Function: int history_set_pos (int pos)
+ Set the current history offset to POS, an absolute index into the
+ list. Returns 1 on success, 0 if POS is less than zero or greater
+ than the number of history entries.
+
+ -- Function: HIST_ENTRY * previous_history (void)
+ Back up the current history offset to the previous history entry,
+ and return a pointer to that entry. If there is no previous entry,
+ return a 'NULL' pointer.
+
+ -- Function: HIST_ENTRY * next_history (void)
+ If the current history offset refers to a valid history entry,
+ increment the current history offset. If the possibly-incremented
+ history offset refers to a valid history entry, return a pointer to
+ that entry; otherwise, return a 'BNULL' pointer.
+
+&#x1f;
+File: history.info, Node: Searching the History List, Next: Managing the History File, Prev: Moving Around the History List, Up: History Functions
+
+2.3.5 Searching the History List
+--------------------------------
+
+These functions allow searching of the history list for entries
+containing a specific string. Searching may be performed both forward
+and backward from the current history position. The search may be
+"anchored", meaning that the string must match at the beginning of the
+history entry.
+
+ -- Function: int history_search (const char *string, int direction)
+ Search the history for STRING, starting at the current history
+ offset. If DIRECTION is less than 0, then the search is through
+ previous entries, otherwise through subsequent entries. If STRING
+ is found, then the current history index is set to that history
+ entry, and the value returned is the offset in the line of the
+ entry where STRING was found. Otherwise, nothing is changed, and a
+ -1 is returned.
+
+ -- Function: int history_search_prefix (const char *string, int
+ direction)
+ Search the history for STRING, starting at the current history
+ offset. The search is anchored: matching lines must begin with
+ STRING. If DIRECTION is less than 0, then the search is through
+ previous entries, otherwise through subsequent entries. If STRING
+ is found, then the current history index is set to that entry, and
+ the return value is 0. Otherwise, nothing is changed, and a -1 is
+ returned.
+
+ -- Function: int history_search_pos (const char *string, int direction,
+ int pos)
+ Search for STRING in the history list, starting at POS, an absolute
+ index into the list. If DIRECTION is negative, the search proceeds
+ backward from POS, otherwise forward. Returns the absolute index
+ of the history element where STRING was found, or -1 otherwise.
+

+
+2.3.6 Managing the History File
+-------------------------------
+
+The History library can read the history from and write it to a file.
+This section documents the functions for managing a history file.
+
+ -- Function: int read_history (const char *filename)
+ Add the contents of FILENAME to the history list, a line at a time.
+ If FILENAME is 'NULL', then read from '~/.history'. Returns 0 if
+ successful, or 'errno' if not.
+
+ -- Function: int read_history_range (const char *filename, int from,
+ int to)
+ Read a range of lines from FILENAME, adding them to the history
+ list. Start reading at line FROM and end at TO. If FROM is zero,
+ start at the beginning. If TO is less than FROM, then read until
+ the end of the file. If FILENAME is 'NULL', then read from
+ '~/.history'. Returns 0 if successful, or 'errno' if not.
+
+ -- Function: int write_history (const char *filename)
+ Write the current history to FILENAME, overwriting FILENAME if
+ necessary. If FILENAME is 'NULL', then write the history list to
+ '~/.history'. Returns 0 on success, or 'errno' on a read or write
+ error.
+
+ -- Function: int append_history (int nelements, const char *filename)
+ Append the last NELEMENTS of the history list to FILENAME. If
+ FILENAME is 'NULL', then append to '~/.history'. Returns 0 on
+ success, or 'errno' on a read or write error.
+
+ -- Function: int history_truncate_file (const char *filename, int
+ nlines)
+ Truncate the history file FILENAME, leaving only the last NLINES
+ lines. If FILENAME is 'NULL', then '~/.history' is truncated.
+ Returns 0 on success, or 'errno' on failure.
+
+&#x1f;
+File: history.info, Node: History Expansion, Prev: Managing the History File, Up: History Functions
+
+2.3.7 History Expansion
+-----------------------
+
+These functions implement history expansion.
+
+ -- Function: int history_expand (char *string, char **output)
+ Expand STRING, placing the result into OUTPUT, a pointer to a
+ string (*note History Interaction::). Returns:
+ '0'
+ If no expansions took place (or, if the only change in the
+ text was the removal of escape characters preceding the
+ history expansion character);
+ '1'
+ if expansions did take place;
+ '-1'
+ if there was an error in expansion;
+ '2'
+ if the returned line should be displayed, but not executed, as
+ with the ':p' modifier (*note Modifiers::).
+
+ If an error occurred in expansion, then OUTPUT contains a
+ descriptive error message.
+
+ -- Function: char * get_history_event (const char *string, int *cindex,
+ int qchar)
+ Returns the text of the history event beginning at STRING +
+ *CINDEX. *CINDEX is modified to point to after the event
+ specifier. At function entry, CINDEX points to the index into
+ STRING where the history event specification begins. QCHAR is a
+ character that is allowed to end the event specification in
+ addition to the "normal" terminating characters.
+
+ -- Function: char ** history_tokenize (const char *string)
+ Return an array of tokens parsed out of STRING, much as the shell
+ might. The tokens are split on the characters in the
+ HISTORY_WORD_DELIMITERS variable, and shell quoting conventions are
+ obeyed as described below.
+
+ -- Function: char * history_arg_extract (int first, int last, const
+ char *string)
+ Extract a string segment consisting of the FIRST through LAST
+ arguments present in STRING. Arguments are split using
+ 'history_tokenize'.

+
+2.4 History Variables
+=====================
+
+This section describes the externally-visible variables exported by the
+GNU History Library.
+
+ -- Variable: int history_base
+ The logical offset of the first entry in the history list.
+
+ -- Variable: int history_length
+ The number of entries currently stored in the history list.
+
+ -- Variable: int history_max_entries
+ The maximum number of history entries. This must be changed using
+ 'stifle_history()'.
+
+ -- Variable: int history_write_timestamps
+ If non-zero, timestamps are written to the history file, so they
+ can be preserved between sessions. The default value is 0, meaning
+ that timestamps are not saved.
+
+ The current timestamp format uses the value of HISTORY_COMMENT_CHAR
+ to delimit timestamp entries in the history file. If that variable
+ does not have a value (the default), timestamps will not be
+ written.
+
+ -- Variable: char history_expansion_char
+ The character that introduces a history event. The default is '!'.
+ Setting this to 0 inhibits history expansion.
+
+ -- Variable: char history_subst_char
+ The character that invokes word substitution if found at the start
+ of a line. The default is '^'.
+
+ -- Variable: char history_comment_char
+ During tokenization, if this character is seen as the first
+ character of a word, then it and all subsequent characters up to a
+ newline are ignored, suppressing history expansion for the
+ remainder of the line. This is disabled by default.
+
+ -- Variable: char * history_word_delimiters
+ The characters that separate tokens for 'history_tokenize()'. The
+ default value is '" \t\n()<>;&|"'.
+
+ -- Variable: char * history_search_delimiter_chars
+ The list of additional characters which can delimit a history
+ search string, in addition to space, TAB, ':' and '?' in the case
+ of a substring search. The default is empty.
+
+ -- Variable: char * history_no_expand_chars
+ The list of characters which inhibit history expansion if found
+ immediately following HISTORY_EXPANSION_CHAR. The default is
+ space, tab, newline, carriage return, and '='.
+
+ -- Variable: int history_quotes_inhibit_expansion
+ If non-zero, the history expansion code implements shell-like
+ quoting: single-quoted words are not scanned for the history
+ expansion character or the history comment character, and
+ double-quoted words may have history expansion performed, since
+ single quotes are not special within double quotes. The default
+ value is 0.
+
+ -- Variable: int history_quoting_state
+ An application may set this variable to indicate that the current
+ line being expanded is subject to existing quoting. If set to ''',
+ the history expansion function will assume that the line is
+ single-quoted and inhibit expansion until it reads an unquoted
+ closing single quote; if set to '"', history expansion will assume
+ the line is double quoted until it reads an unquoted closing double
+ quote. If set to zero, the default, the history expansion function
+ will assume the line is not quoted and treat quote characters
+ within the line as described above. This is only effective if
+ HISTORY_QUOTES_INHIBIT_EXPANSION is set.
+
+ -- Variable: rl_linebuf_func_t * history_inhibit_expansion_function
+ This should be set to the address of a function that takes two
+ arguments: a 'char *' (STRING) and an 'int' index into that string
+ (I). It should return a non-zero value if the history expansion
+ starting at STRINGI should not be performed; zero if the
+ expansion should be done. It is intended for use by applications
+ like Bash that use the history expansion character for additional
+ purposes. By default, this variable is set to 'NULL'.

+ author and publisher a way to get credit for their work, while not
+ being considered responsible for modifications made by others.
+
+ This License is a kind of "copyleft", which means that derivative
+ works of the document must themselves be free in the same sense.
+ It complements the GNU General Public License, which is a copyleft
+ license designed for free software.
+
+ We have designed this License in order to use it for manuals for
+ free software, because free software needs free documentation: a
+ free program should come with manuals providing the same freedoms
+ that the software does. But this License is not limited to
+ software manuals; it can be used for any textual work, regardless
+ of subject matter or whether it is published as a printed book. We
+ recommend this License principally for works whose purpose is
+ instruction or reference.
+
+ 1. APPLICABILITY AND DEFINITIONS
+
+ This License applies to any manual or other work, in any medium,
+ that contains a notice placed by the copyright holder saying it can
+ be distributed under the terms of this License. Such a notice
+ grants a world-wide, royalty-free license, unlimited in duration,
+ to use that work under the conditions stated herein. The
+ "Document", below, refers to any such manual or work. Any member
+ of the public is a licensee, and is addressed as "you". You accept
+ the license if you copy, modify or distribute the work in a way
+ requiring permission under copyright law.
+
+ A "Modified Version" of the Document means any work containing the
+ Document or a portion of it, either copied verbatim, or with
+ modifications and/or translated into another language.
+
+ A "Secondary Section" is a named appendix or a front-matter section
+ of the Document that deals exclusively with the relationship of the
+ publishers or authors of the Document to the Document's overall
+ subject (or to related matters) and contains nothing that could
+ fall directly within that overall subject. (Thus, if the Document
+ is in part a textbook of mathematics, a Secondary Section may not
+ explain any mathematics.) The relationship could be a matter of
+ historical connection with the subject or with related matters, or
+ of legal, commercial, philosophical, ethical or political position
+ regarding them.
+
+ The "Invariant Sections" are certain Secondary Sections whose
+ titles are designated, as being those of Invariant Sections, in the
+ notice that says that the Document is released under this License.
+ If a section does not fit the above definition of Secondary then it
+ is not allowed to be designated as Invariant. The Document may
+ contain zero Invariant Sections. If the Document does not identify
+ any Invariant Sections then there are none.
+
+ The "Cover Texts" are certain short passages of text that are
+ listed, as Front-Cover Texts or Back-Cover Texts, in the notice
+ that says that the Document is released under this License. A
+ Front-Cover Text may be at most 5 words, and a Back-Cover Text may
+ be at most 25 words.
+
+ A "Transparent" copy of the Document means a machine-readable copy,
+ represented in a format whose specification is available to the
+ general public, that is suitable for revising the document
+ straightforwardly with generic text editors or (for images composed
+ of pixels) generic paint programs or (for drawings) some widely
+ available drawing editor, and that is suitable for input to text
+ formatters or for automatic translation to a variety of formats
+ suitable for input to text formatters. A copy made in an otherwise
+ Transparent file format whose markup, or absence of markup, has
+ been arranged to thwart or discourage subsequent modification by
+ readers is not Transparent. An image format is not Transparent if
+ used for any substantial amount of text. A copy that is not
+ "Transparent" is called "Opaque".
+
+ Examples of suitable formats for Transparent copies include plain
+ ASCII without markup, Texinfo input format, LaTeX input format,
+ SGML or XML using a publicly available DTD, and standard-conforming
+ simple HTML, PostScript or PDF designed for human modification.
+ Examples of transparent image formats include PNG, XCF and JPG.
+ Opaque formats include proprietary formats that can be read and
+ edited only by proprietary word processors, SGML or XML for which
+ the DTD and/or processing tools are not generally available, and
+ the machine-generated HTML, PostScript or PDF produced by some word
+ processors for output purposes only.
+
+ The "Title Page" means, for a printed book, the title page itself,
+ plus such following pages as are needed to hold, legibly, the
+ material this License requires to appear in the title page. For
+ works in formats which do not have any title page as such, "Title
+ Page" means the text near the most prominent appearance of the
+ work's title, preceding the beginning of the body of the text.
+
+ The "publisher" means any person or entity that distributes copies
+ of the Document to the public.
+
+ A section "Entitled XYZ" means a named subunit of the Document
+ whose title either is precisely XYZ or contains XYZ in parentheses
+ following text that translates XYZ in another language. (Here XYZ
+ stands for a specific section name mentioned below, such as
+ "Acknowledgements", "Dedications", "Endorsements", or "History".)
+ To "Preserve the Title" of such a section when you modify the
+ Document means that it remains a section "Entitled XYZ" according
+ to this definition.
+
+ The Document may include Warranty Disclaimers next to the notice
+ which states that this License applies to the Document. These
+ Warranty Disclaimers are considered to be included by reference in
+ this License, but only as regards disclaiming warranties: any other
+ implication that these Warranty Disclaimers may have is void and
+ has no effect on the meaning of this License.
+
+ 2. VERBATIM COPYING
+
+ You may copy and distribute the Document in any medium, either
+ commercially or noncommercially, provided that this License, the
+ copyright notices, and the license notice saying this License
+ applies to the Document are reproduced in all copies, and that you
+ add no other conditions whatsoever to those of this License. You
+ may not use technical measures to obstruct or control the reading
+ or further copying of the copies you make or distribute. However,
+ you may accept compensation in exchange for copies. If you
+ distribute a large enough number of copies you must also follow the
+ conditions in section 3.
+
+ You may also lend copies, under the same conditions stated above,
+ and you may publicly display copies.
+
+ 3. COPYING IN QUANTITY
+
+ If you publish printed copies (or copies in media that commonly
+ have printed covers) of the Document, numbering more than 100, and
+ the Document's license notice requires Cover Texts, you must
+ enclose the copies in covers that carry, clearly and legibly, all
+ these Cover Texts: Front-Cover Texts on the front cover, and
+ Back-Cover Texts on the back cover. Both covers must also clearly
+ and legibly identify you as the publisher of these copies. The
+ front cover must present the full title with all words of the title
+ equally prominent and visible. You may add other material on the
+ covers in addition. Copying with changes limited to the covers, as
+ long as they preserve the title of the Document and satisfy these
+ conditions, can be treated as verbatim copying in other respects.
+
+ If the required texts for either cover are too voluminous to fit
+ legibly, you should put the first ones listed (as many as fit
+ reasonably) on the actual cover, and continue the rest onto
+ adjacent pages.
+
+ If you publish or distribute Opaque copies of the Document
+ numbering more than 100, you must either include a machine-readable
+ Transparent copy along with each Opaque copy, or state in or with
+ each Opaque copy a computer-network location from which the general
+ network-using public has access to download using public-standard
+ network protocols a complete Transparent copy of the Document, free
+ of added material. If you use the latter option, you must take
+ reasonably prudent steps, when you begin distribution of Opaque
+ copies in quantity, to ensure that this Transparent copy will
+ remain thus accessible at the stated location until at least one
+ year after the last time you distribute an Opaque copy (directly or
+ through your agents or retailers) of that edition to the public.
+
+ It is requested, but not required, that you contact the authors of
+ the Document well before redistributing any large number of copies,
+ to give them a chance to provide you with an updated version of the
+ Document.
+
+ 4. MODIFICATIONS
+
+ You may copy and distribute a Modified Version of the Document
+ under the conditions of sections 2 and 3 above, provided that you
+ release the Modified Version under precisely this License, with the
+ Modified Version filling the role of the Document, thus licensing
+ distribution and modification of the Modified Version to whoever
+ possesses a copy of it. In addition, you must do these things in
+ the Modified Version:
+
+ A. Use in the Title Page (and on the covers, if any) a title
+ distinct from that of the Document, and from those of previous
+ versions (which should, if there were any, be listed in the
+ History section of the Document). You may use the same title
+ as a previous version if the original publisher of that
+ version gives permission.
+
+ B. List on the Title Page, as authors, one or more persons or
+ entities responsible for authorship of the modifications in
+ the Modified Version, together with at least five of the
+ principal authors of the Document (all of its principal
+ authors, if it has fewer than five), unless they release you
+ from this requirement.
+
+ C. State on the Title page the name of the publisher of the
+ Modified Version, as the publisher.
+
+ D. Preserve all the copyright notices of the Document.
+
+ E. Add an appropriate copyright notice for your modifications
+ adjacent to the other copyright notices.
+
+ F. Include, immediately after the copyright notices, a license
+ notice giving the public permission to use the Modified
+ Version under the terms of this License, in the form shown in
+ the Addendum below.
+
+ G. Preserve in that license notice the full lists of Invariant
+ Sections and required Cover Texts given in the Document's
+ license notice.
+
+ H. Include an unaltered copy of this License.
+
+ I. Preserve the section Entitled "History", Preserve its Title,
+ and add to it an item stating at least the title, year, new
+ authors, and publisher of the Modified Version as given on the
+ Title Page. If there is no section Entitled "History" in the
+ Document, create one stating the title, year, authors, and
+ publisher of the Document as given on its Title Page, then add
+ an item describing the Modified Version as stated in the
+ previous sentence.
+
+ J. Preserve the network location, if any, given in the Document
+ for public access to a Transparent copy of the Document, and
+ likewise the network locations given in the Document for
+ previous versions it was based on. These may be placed in the
+ "History" section. You may omit a network location for a work
+ that was published at least four years before the Document
+ itself, or if the original publisher of the version it refers
+ to gives permission.
+
+ K. For any section Entitled "Acknowledgements" or "Dedications",
+ Preserve the Title of the section, and preserve in the section
+ all the substance and tone of each of the contributor
+ acknowledgements and/or dedications given therein.
+
+ L. Preserve all the Invariant Sections of the Document, unaltered
+ in their text and in their titles. Section numbers or the
+ equivalent are not considered part of the section titles.
+
+ M. Delete any section Entitled "Endorsements". Such a section
+ may not be included in the Modified Version.
+
+ N. Do not retitle any existing section to be Entitled
+ "Endorsements" or to conflict in title with any Invariant
+ Section.
+
+ O. Preserve any Warranty Disclaimers.
+
+ If the Modified Version includes new front-matter sections or
+ appendices that qualify as Secondary Sections and contain no
+ material copied from the Document, you may at your option designate
+ some or all of these sections as invariant. To do this, add their
+ titles to the list of Invariant Sections in the Modified Version's
+ license notice. These titles must be distinct from any other
+ section titles.
+
+ You may add a section Entitled "Endorsements", provided it contains
+ nothing but endorsements of your Modified Version by various
+ parties--for example, statements of peer review or that the text
+ has been approved by an organization as the authoritative
+ definition of a standard.
+
+ You may add a passage of up to five words as a Front-Cover Text,
+ and a passage of up to 25 words as a Back-Cover Text, to the end of
+ the list of Cover Texts in the Modified Version. Only one passage
+ of Front-Cover Text and one of Back-Cover Text may be added by (or
+ through arrangements made by) any one entity. If the Document
+ already includes a cover text for the same cover, previously added
+ by you or by arrangement made by the same entity you are acting on
+ behalf of, you may not add another; but you may replace the old
+ one, on explicit permission from the previous publisher that added
+ the old one.
+
+ The author(s) and publisher(s) of the Document do not by this
+ License give permission to use their names for publicity for or to
+ assert or imply endorsement of any Modified Version.
+
+ 5. COMBINING DOCUMENTS
+
+ You may combine the Document with other documents released under
+ this License, under the terms defined in section 4 above for
+ modified versions, provided that you include in the combination all
+ of the Invariant Sections of all of the original documents,
+ unmodified, and list them all as Invariant Sections of your
+ combined work in its license notice, and that you preserve all
+ their Warranty Disclaimers.
+
+ The combined work need only contain one copy of this License, and
+ multiple identical Invariant Sections may be replaced with a single
+ copy. If there are multiple Invariant Sections with the same name
+ but different contents, make the title of each such section unique
+ by adding at the end of it, in parentheses, the name of the
+ original author or publisher of that section if known, or else a
+ unique number. Make the same adjustment to the section titles in
+ the list of Invariant Sections in the license notice of the
+ combined work.
+
+ In the combination, you must combine any sections Entitled
+ "History" in the various original documents, forming one section
+ Entitled "History"; likewise combine any sections Entitled
+ "Acknowledgements", and any sections Entitled "Dedications". You
+ must delete all sections Entitled "Endorsements."
+
+ 6. COLLECTIONS OF DOCUMENTS
+
+ You may make a collection consisting of the Document and other
+ documents released under this License, and replace the individual
+ copies of this License in the various documents with a single copy
+ that is included in the collection, provided that you follow the
+ rules of this License for verbatim copying of each of the documents
+ in all other respects.
+
+ You may extract a single document from such a collection, and
+ distribute it individually under this License, provided you insert
+ a copy of this License into the extracted document, and follow this
+ License in all other respects regarding verbatim copying of that
+ document.
+
+ 7. AGGREGATION WITH INDEPENDENT WORKS
+
+ A compilation of the Document or its derivatives with other
+ separate and independent documents or works, in or on a volume of a
+ storage or distribution medium, is called an "aggregate" if the
+ copyright resulting from the compilation is not used to limit the
+ legal rights of the compilation's users beyond what the individual
+ works permit. When the Document is included in an aggregate, this
+ License does not apply to the other works in the aggregate which
+ are not themselves derivative works of the Document.
+
+ If the Cover Text requirement of section 3 is applicable to these
+ copies of the Document, then if the Document is less than one half
+ of the entire aggregate, the Document's Cover Texts may be placed
+ on covers that bracket the Document within the aggregate, or the
+ electronic equivalent of covers if the Document is in electronic
+ form. Otherwise they must appear on printed covers that bracket
+ the whole aggregate.
+
+ 8. TRANSLATION
+
+ Translation is considered a kind of modification, so you may
+ distribute translations of the Document under the terms of section
+ 4. Replacing Invariant Sections with translations requires special
+ permission from their copyright holders, but you may include
+ translations of some or all Invariant Sections in addition to the
+ original versions of these Invariant Sections. You may include a
+ translation of this License, and all the license notices in the
+ Document, and any Warranty Disclaimers, provided that you also
+ include the original English version of this License and the
+ original versions of those notices and disclaimers. In case of a
+ disagreement between the translation and the original version of
+ this License or a notice or disclaimer, the original version will
+ prevail.
+
+ If a section in the Document is Entitled "Acknowledgements",
+ "Dedications", or "History", the requirement (section 4) to
+ Preserve its Title (section 1) will typically require changing the
+ actual title.
+
+ 9. TERMINATION
+
+ You may not copy, modify, sublicense, or distribute the Document
+ except as expressly provided under this License. Any attempt
+ otherwise to copy, modify, sublicense, or distribute it is void,
+ and will automatically terminate your rights under this License.
+
+ However, if you cease all violation of this License, then your
+ license from a particular copyright holder is reinstated (a)
+ provisionally, unless and until the copyright holder explicitly and
+ finally terminates your license, and (b) permanently, if the
+ copyright holder fails to notify you of the violation by some
+ reasonable means prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+ reinstated permanently if the copyright holder notifies you of the
+ violation by some reasonable means, this is the first time you have
+ received notice of violation of this License (for any work) from
+ that copyright holder, and you cure the violation prior to 30 days
+ after your receipt of the notice.
+
+ Termination of your rights under this section does not terminate
+ the licenses of parties who have received copies or rights from you
+ under this License. If your rights have been terminated and not
+ permanently reinstated, receipt of a copy of some or all of the
+ same material does not give you any rights to use it.
+
+ 10. FUTURE REVISIONS OF THIS LICENSE
+
+ The Free Software Foundation may publish new, revised versions of
+ the GNU Free Documentation License from time to time. Such new
+ versions will be similar in spirit to the present version, but may
+ differ in detail to address new problems or concerns. See
+ <http://www.gnu.org/copyleft/>.
+
+ Each version of the License is given a distinguishing version
+ number. If the Document specifies that a particular numbered
+ version of this License "or any later version" applies to it, you
+ have the option of following the terms and conditions either of
+ that specified version or of any later version that has been
+ published (not as a draft) by the Free Software Foundation. If the
+ Document does not specify a version number of this License, you may
+ choose any version ever published (not as a draft) by the Free
+ Software Foundation. If the Document specifies that a proxy can
+ decide which future versions of this License can be used, that
+ proxy's public statement of acceptance of a version permanently
+ authorizes you to choose that version for the Document.
+
+ 11. RELICENSING
+
+ "Massive Multiauthor Collaboration Site" (or "MMC Site") means any
+ World Wide Web server that publishes copyrightable works and also
+ provides prominent facilities for anybody to edit those works. A
+ public wiki that anybody can edit is an example of such a server.
+ A "Massive Multiauthor Collaboration" (or "MMC") contained in the
+ site means any set of copyrightable works thus published on the MMC
+ site.
+
+ "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0
+ license published by Creative Commons Corporation, a not-for-profit
+ corporation with a principal place of business in San Francisco,
+ California, as well as future copyleft versions of that license
+ published by that same organization.
+
+ "Incorporate" means to publish or republish a Document, in whole or
+ in part, as part of another Document.
+
+ An MMC is "eligible for relicensing" if it is licensed under this
+ License, and if all works that were first published under this
+ License somewhere other than this MMC, and subsequently
+ incorporated in whole or in part into the MMC, (1) had no cover
+ texts or invariant sections, and (2) were thus incorporated prior
+ to November 1, 2008.
+
+ The operator of an MMC Site may republish an MMC contained in the
+ site under CC-BY-SA on the same site at any time before August 1,
+ 2009, provided the MMC is eligible for relicensing.
+
+ADDENDUM: How to use this License for your documents
+====================================================
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and license
+notices just after the title page:
+
+ Copyright (C) YEAR YOUR NAME.
+ Permission is granted to copy, distribute and/or modify this document
+ under the terms of the GNU Free Documentation License, Version 1.3
+ or any later version published by the Free Software Foundation;
+ with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
+ Texts. A copy of the license is included in the section entitled ``GNU
+ Free Documentation License''.
+
+ If you have Invariant Sections, Front-Cover Texts and Back-Cover
+Texts, replace the "with...Texts." line with this:
+
+ with the Invariant Sections being LIST THEIR TITLES, with
+ the Front-Cover Texts being LIST, and with the Back-Cover Texts
+ being LIST.
+
+ If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+
+ If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of free
+software license, such as the GNU General Public License, to permit
+their use in free software.

+@chapter Programming with GNU History
+
+This chapter describes how to interface programs that you write
+with the @sc{gnu} History Library.
+It should be considered a technical guide.
+For information on the interactive use of @sc{gnu} History, @pxref{Using
+History Interactively}.

+@node Introduction to History
+@section Introduction to History
+
+Many programs read input from the user a line at a time. The @sc{gnu}
+History library is able to keep track of those lines, associate arbitrary
+data with each line, and utilize information from previous lines in
+composing new ones. 
+
+A programmer using the History library has available functions
+for remembering lines on a history list, associating arbitrary data
+with a line, removing lines from the list, searching through the list
+for a line containing an arbitrary text string, and referencing any line
+in the list directly. In addition, a history @dfn{expansion} function
+is available which provides for a consistent user interface across
+different programs.
+
+The user using programs written with the History library has the
+benefit of a consistent user interface with a set of well-known
+commands for manipulating the text of previous lines and using that text
+in new commands. The basic history manipulation commands are similar to
+the history substitution provided by @code{csh}.
+
+The programmer can also use the Readline library, which
+includes some history manipulation by default, and has the added
+advantage of command line editing.
+
+Before declaring any functions using any functionality the History
+library provides in other code, an application writer should include
+the file @code{<readline/history.h>} in any file that uses the
+History library's features. It supplies extern declarations for all
+of the library's public functions and variables, and declares all of
+the public data structures.
+
+@node History Storage
+@section History Storage
+
+The history list is an array of history entries. A history entry is
+declared as follows:
+
+@example
+typedef void *histdata_t;
+
+typedef struct _hist_entry @{
+ char *line;
+ char *timestamp;
+ histdata_t data;
+@} HIST_ENTRY;
+@end example
+
+The history list itself might therefore be declared as
+
+@example
+HIST_ENTRY **the_history_list;
+@end example
+
+The state of the History library is encapsulated into a single structure:
+
+@example
+/*
+ * A structure used to pass around the current state of the history.
+ */
+typedef struct _hist_state @{
+ HIST_ENTRY **entries; /* Pointer to the entries themselves. */
+ int offset; /* The location pointer within this array. */
+ int length; /* Number of elements within this array. */
+ int size; /* Number of slots allocated to this array. */
+ int flags;
+@} HISTORY_STATE;
+@end example
+
+If the flags member includes @code{HS_STIFLED}, the history has been
+stifled.
+
+@node History Functions
+@section History Functions
+
+This section describes the calling sequence for the various functions
+exported by the @sc{gnu} History library.
+
+@menu
+* Initializing History and State Management::	Functions to call when you
+						want to use history in a

+
+@node Initializing History and State Management
+@subsection Initializing History and State Management
+
+This section describes functions used to initialize and manage
+the state of the History library when you want to use the history
+functions in your program.
+
+@deftypefun void using_history (void)
+Begin a session in which the history functions might be used. This
+initializes the interactive variables.
+@end deftypefun
+
+@deftypefun {HISTORY_STATE *} history_get_history_state (void)
+Return a structure describing the current state of the input history.
+@end deftypefun
+
+@deftypefun void history_set_history_state (HISTORY_STATE *state)
+Set the state of the history list according to @var{state}.
+@end deftypefun
+
+@node History List Management
+@subsection History List Management
+
+These functions manage individual entries on the history list, or set
+parameters managing the list itself.
+
+@deftypefun void add_history (const char *string)
+Place @var{string} at the end of the history list. The associated data
+field (if any) is set to @code{NULL}.
+If the maximum number of history entries has been set using
+@code{stifle_history()}, and the new number of history entries would exceed
+that maximum, the oldest history entry is removed.
+@end deftypefun
+
+@deftypefun void add_history_time (const char *string)
+Change the time stamp associated with the most recent history entry to
+@var{string}.
+@end deftypefun
+
+@deftypefun {HIST_ENTRY *} remove_history (int which)
+Remove history entry at offset @var{which} from the history. The
+removed element is returned so you can free the line, data,
+and containing structure.
+@end deftypefun
+
+@deftypefun {histdata_t} free_history_entry (HIST_ENTRY *histent)
+Free the history entry @var{histent} and any history library private
+data associated with it. Returns the application-specific data
+so the caller can dispose of it.
+@end deftypefun
+
+@deftypefun {HIST_ENTRY *} replace_history_entry (int which, const char *line, histdata_t data)
+Make the history entry at offset @var{which} have @var{line} and @var{data}.
+This returns the old entry so the caller can dispose of any
+application-specific data. In the case
+of an invalid @var{which}, a @code{NULL} pointer is returned.
+@end deftypefun
+
+@deftypefun void clear_history (void)
+Clear the history list by deleting all the entries.
+@end deftypefun
+
+@deftypefun void stifle_history (int max)
+Stifle the history list, remembering only the last @var{max} entries.
+The history list will contain only @var{max} entries at a time.
+@end deftypefun
+
+@deftypefun int unstifle_history (void)
+Stop stifling the history. This returns the previously-set
+maximum number of history entries (as set by @code{stifle_history()}).
+The value is positive if the history was
+stifled, negative if it wasn't.
+@end deftypefun
+
+@deftypefun int history_is_stifled (void)
+Returns non-zero if the history is stifled, zero if it is not.
+@end deftypefun
+
+@node Information About the History List
+@subsection Information About the History List
+
+These functions return information about the entire history list or
+individual list entries.
+
+@deftypefun {HIST_ENTRY **} history_list (void)
+Return a @code{NULL} terminated array of @code{HIST_ENTRY *} which is the
+current input history. Element 0 of this list is the beginning of time.
+If there is no history, return @code{NULL}.
+@end deftypefun
+
+@deftypefun int where_history (void)
+Returns the offset of the current history element.
+@end deftypefun
+
+@deftypefun {HIST_ENTRY *} current_history (void)
+Return the history entry at the current position, as determined by
+@code{where_history()}. If there is no entry there, return a @code{NULL}
+pointer.
+@end deftypefun
+
+@deftypefun {HIST_ENTRY *} history_get (int offset)
+Return the history entry at position @var{offset}.
+The range of valid
+values of @var{offset} starts at @code{history_base} and ends at
+@var{history_length} - 1 (@pxref{History Variables}).
+If there is no entry there, or if @var{offset} is outside the valid
+range, return a @code{NULL} pointer.
+@end deftypefun
+
+@deftypefun time_t history_get_time (HIST_ENTRY *entry)
+Return the time stamp associated with the history entry @var{entry}.
+If the timestamp is missing or invalid, return 0.
+@end deftypefun
+
+@deftypefun int history_total_bytes (void)
+Return the number of bytes that the primary history entries are using.
+This function returns the sum of the lengths of all the lines in the
+history.
+@end deftypefun
+
+@node Moving Around the History List
+@subsection Moving Around the History List
+
+These functions allow the current index into the history list to be
+set or changed.
+
+@deftypefun int history_set_pos (int pos)
+Set the current history offset to @var{pos}, an absolute index
+into the list.
+Returns 1 on success, 0 if @var{pos} is less than zero or greater
+than the number of history entries.
+@end deftypefun
+
+@deftypefun {HIST_ENTRY *} previous_history (void)
+Back up the current history offset to the previous history entry, and
+return a pointer to that entry. If there is no previous entry, return
+a @code{NULL} pointer.
+@end deftypefun
+
+@deftypefun {HIST_ENTRY *} next_history (void)
+If the current history offset refers to a valid history entry,
+increment the current history offset.
+If the possibly-incremented history offset refers to a valid history
+entry, return a pointer to that entry;
+otherwise, return a @code{BNULL} pointer.
+@end deftypefun
+
+@node Searching the History List
+@subsection Searching the History List
+@cindex History Searching
+
+These functions allow searching of the history list for entries containing
+a specific string. Searching may be performed both forward and backward
+from the current history position. The search may be @dfn{anchored},
+meaning that the string must match at the beginning of the history entry.
+@cindex anchored search
+
+@deftypefun int history_search (const char *string, int direction)
+Search the history for @var{string}, starting at the current history offset.
+If @var{direction} is less than 0, then the search is through
+previous entries, otherwise through subsequent entries.
+If @var{string} is found, then
+the current history index is set to that history entry, and the value
+returned is the offset in the line of the entry where
+@var{string} was found. Otherwise, nothing is changed, and a -1 is
+returned.
+@end deftypefun
+
+@deftypefun int history_search_prefix (const char *string, int direction)
+Search the history for @var{string}, starting at the current history
+offset. The search is anchored: matching lines must begin with
+@var{string}. If @var{direction} is less than 0, then the search is
+through previous entries, otherwise through subsequent entries.
+If @var{string} is found, then the
+current history index is set to that entry, and the return value is 0. 
+Otherwise, nothing is changed, and a -1 is returned. 
+@end deftypefun
+
+@deftypefun int history_search_pos (const char *string, int direction, int pos)
+Search for @var{string} in the history list, starting at @var{pos}, an
+absolute index into the list. If @var{direction} is negative, the search
+proceeds backward from @var{pos}, otherwise forward. Returns the absolute
+index of the history element where @var{string} was found, or -1 otherwise.
+@end deftypefun
+
+@node Managing the History File
+@subsection Managing the History File
+
+The History library can read the history from and write it to a file.
+This section documents the functions for managing a history file.
+
+@deftypefun int read_history (const char *filename)
+Add the contents of @var{filename} to the history list, a line at a time.
+If @var{filename} is @code{NULL}, then read from @file{~/.history}.
+Returns 0 if successful, or @code{errno} if not.
+@end deftypefun
+
+@deftypefun int read_history_range (const char *filename, int from, int to)
+Read a range of lines from @var{filename}, adding them to the history list.
+Start reading at line @var{from} and end at @var{to}.
+If @var{from} is zero, start at the beginning. If @var{to} is less than
+@var{from}, then read until the end of the file. If @var{filename} is
+@code{NULL}, then read from @file{~/.history}. Returns 0 if successful,
+or @code{errno} if not.
+@end deftypefun
+
+@deftypefun int write_history (const char *filename)
+Write the current history to @var{filename}, overwriting @var{filename}
+if necessary.
+If @var{filename} is @code{NULL}, then write the history list to
+@file{~/.history}.
+Returns 0 on success, or @code{errno} on a read or write error.
+@end deftypefun
+
+@deftypefun int append_history (int nelements, const char *filename)
+Append the last @var{nelements} of the history list to @var{filename}.
+If @var{filename} is @code{NULL}, then append to @file{~/.history}.
+Returns 0 on success, or @code{errno} on a read or write error.
+@end deftypefun
+
+@deftypefun int history_truncate_file (const char *filename, int nlines)
+Truncate the history file @var{filename}, leaving only the last
+@var{nlines} lines.
+If @var{filename} is @code{NULL}, then @file{~/.history} is truncated.
+Returns 0 on success, or @code{errno} on failure.
+@end deftypefun
+
+@node History Expansion
+@subsection History Expansion
+
+These functions implement history expansion.
+
+@deftypefun int history_expand (char *string, char **output)
+Expand @var{string}, placing the result into @var{output}, a pointer
+to a string (@pxref{History Interaction}). Returns:
+@table @code
+@item 0
+If no expansions took place (or, if the only change in
+the text was the removal of escape characters preceding the history expansion
+character);
+@item 1
+if expansions did take place;
+@item -1
+if there was an error in expansion;
+@item 2
+if the returned line should be displayed, but not executed,
+as with the @code{:p} modifier (@pxref{Modifiers}).
+@end table
+
+If an error occurred in expansion, then @var{output} contains a descriptive
+error message.
+@end deftypefun
+
+@deftypefun {char *} get_history_event (const char *string, int *cindex, int qchar)
+Returns the text of the history event beginning at @var{string} +
+@var{*cindex}. @var{*cindex} is modified to point to after the event
+specifier. At function entry, @var{cindex} points to the index into
+@var{string} where the history event specification begins. @var{qchar}
+is a character that is allowed to end the event specification in addition
+to the ``normal'' terminating characters.
+@end deftypefun
+
+@deftypefun {char **} history_tokenize (const char *string)
+Return an array of tokens parsed out of @var{string}, much as the
+shell might. The tokens are split on the characters in the
+@var{history_word_delimiters} variable,
+and shell quoting conventions are obeyed as described below.
+@end deftypefun
+
+@deftypefun {char *} history_arg_extract (int first, int last, const char *string)
+Extract a string segment consisting of the @var{first} through @var{last}
+arguments present in @var{string}. Arguments are split using
+@code{history_tokenize}.
+@end deftypefun
+
+@node History Variables
+@section History Variables
+
+This section describes the externally-visible variables exported by
+the @sc{gnu} History Library.
+
+@deftypevar int history_base
+The logical offset of the first entry in the history list.
+@end deftypevar
+
+@deftypevar int history_length
+The number of entries currently stored in the history list.
+@end deftypevar
+
+@deftypevar int history_max_entries
+The maximum number of history entries. This must be changed using
+@code{stifle_history()}.
+@end deftypevar
+
+@deftypevar int history_write_timestamps
+If non-zero, timestamps are written to the history file, so they can be
+preserved between sessions. The default value is 0, meaning that
+timestamps are not saved.
+
+The current timestamp format uses the value of @var{history_comment_char}
+to delimit timestamp entries in the history file. If that variable does
+not have a value (the default), timestamps will not be written.
+@end deftypevar
+
+@deftypevar char history_expansion_char
+The character that introduces a history event. The default is @samp{!}.
+Setting this to 0 inhibits history expansion.
+@end deftypevar
+
+@deftypevar char history_subst_char
+The character that invokes word substitution if found at the start of
+a line. The default is @samp{^}.
+@end deftypevar
+
+@deftypevar char history_comment_char
+During tokenization, if this character is seen as the first character
+of a word, then it and all subsequent characters up to a newline are
+ignored, suppressing history expansion for the remainder of the line.
+This is disabled by default.
+@end deftypevar
+
+@deftypevar {char *} history_word_delimiters
+The characters that separate tokens for @code{history_tokenize()}.
+The default value is @code{" \t\n()<>;&|"}.
+@end deftypevar
+
+@deftypevar {char *} history_search_delimiter_chars
+The list of additional characters which can delimit a history search
+string, in addition to space, TAB, @samp{:} and @samp{?} in the case of
+a substring search. The default is empty.
+@end deftypevar
+
+@deftypevar {char *} history_no_expand_chars
+The list of characters which inhibit history expansion if found immediately
+following @var{history_expansion_char}. The default is space, tab, newline,
+carriage return, and @samp{=}.
+@end deftypevar
+
+@deftypevar int history_quotes_inhibit_expansion
+If non-zero, the history expansion code implements shell-like quoting:
+single-quoted words are not scanned for the history expansion
+character or the history comment character, and double-quoted words may
+have history expansion performed, since single quotes are not special
+within double quotes.
+The default value is 0.
+@end deftypevar
+
+@deftypevar int history_quoting_state
+An application may set this variable to indicate that the current line
+being expanded is subject to existing quoting. If set to @samp{'}, the
+history expansion function will assume that the line is single-quoted and
+inhibit expansion until it reads an unquoted closing single quote; if set
+to @samp{"}, history expansion will assume the line is double quoted until
+it reads an unquoted closing double quote. If set to zero, the default,
+the history expansion function will assume the line is not quoted and
+treat quote characters within the line as described above.
+This is only effective if @var{history_quotes_inhibit_expansion} is set.
+@end deftypevar
+
+@deftypevar {rl_linebuf_func_t *} history_inhibit_expansion_function
+This should be set to the address of a function that takes two arguments:
+a @code{char *} (@var{string})
+and an @code{int} index into that string (@var{i}).
+It should return a non-zero value if the history expansion starting at
+@var{stringi} should not be performed; zero if the expansion should
+be done.
+It is intended for use by applications like Bash that use the history
+expansion character for additional purposes.
+By default, this variable is set to @code{NULL}.

+commands (default 500) is saved.
+The shell stores each command in the history list prior to
+parameter and variable expansion
+but after history expansion is performed, subject to the
+values of the shell variables
+@env{HISTIGNORE} and @env{HISTCONTROL}.
+
+When the shell starts up, the history is initialized from the
+file named by the @env{HISTFILE} variable (default @file{~/.bash_history}).
+The file named by the value of @env{HISTFILE} is truncated, if
+necessary, to contain no more than the number of lines specified by
+the value of the @env{HISTFILESIZE} variable.
+When a shell with history enabled exits, the last
+@env{$HISTSIZE} lines are copied from the history list to the file
+named by @env{$HISTFILE}.
+If the @code{histappend} shell option is set (@pxref{Bash Builtins}),
+the lines are appended to the history file,
+otherwise the history file is overwritten.
+If @env{HISTFILE}
+is unset, or if the history file is unwritable, the history is not saved.
+After saving the history, the history file is truncated
+to contain no more than @env{$HISTFILESIZE} lines.
+If @env{HISTFILESIZE} is unset, or set to null, a non-numeric value, or
+a numeric value less than zero, the history file is not truncated.
+
+If the @env{HISTTIMEFORMAT} is set, the time stamp information
+associated with each history entry is written to the history file,
+marked with the history comment character.
+When the history file is read, lines beginning with the history
+comment character followed immediately by a digit are interpreted
+as timestamps for the following history entry.
+
+The builtin command @code{fc} may be used to list or edit and re-execute
+a portion of the history list.
+The @code{history} builtin may be used to display or modify the history
+list and manipulate the history file.
+When using command-line editing, search commands
+are available in each editing mode that provide access to the
+history list (@pxref{Commands For History}).
+
+The shell allows control over which commands are saved on the history
+list.  The @env{HISTCONTROL} and @env{HISTIGNORE}
+variables may be set to cause the shell to save only a subset of the
+commands entered.
+The @code{cmdhist}
+shell option, if enabled, causes the shell to attempt to save each
+line of a multi-line command in the same history entry, adding
+semicolons where necessary to preserve syntactic correctness.
+The @code{lithist}
+shell option causes the shell to save the command with embedded newlines
+instead of semicolons.
+The @code{shopt} builtin is used to set these options.
+@xref{The Shopt Builtin}, for a description of @code{shopt}.
+
+@node Bash History Builtins
+@section Bash History Builtins
+@cindex history builtins
+
+Bash provides two builtin commands which manipulate the
+history list and history file.
+
+@table @code
+
+@item fc
+@btindex fc
+@example
+@code{fc -e @var{ename} -lnr @var{first} @var{last}}
+@code{fc -s @var{pat}=@var{rep} @var{command}}
+@end example
+
+The first form selects a range of commands from @var{first} to
+@var{last} from the history list and displays or edits and re-executes
+them.
+Both @var{first} and
+@var{last} may be specified as a string (to locate the most recent
+command beginning with that string) or as a number (an index into the
+history list, where a negative number is used as an offset from the
+current command number).
+
+When listing, a @var{first} or @var{last} of 0 is equivalent to -1
+and -0 is equivalent to the current command (usually the @code{fc}
+command);
+otherwise 0 is equivalent to -1 and -0 is invalid.
+
+If @var{last} is not specified, it is set to
+@var{first}.  If @var{first} is not specified, it is set to the previous
+command for editing and @minus{}16 for listing.  If the @option{-l} flag is
+given, the commands are listed on standard output.  The @option{-n} flag
+suppresses the command numbers when listing.  The @option{-r} flag
+reverses the order of the listing.  Otherwise, the editor given by
+@var{ename} is invoked on a file containing those commands.  If
+@var{ename} is not given, the value of the following variable expansion
+is used: @code{$@{FCEDIT:-$@{EDITOR:-vi@}@}}.  This says to use the
+value of the @env{FCEDIT} variable if set, or the value of the
+@env{EDITOR} variable if that is set, or @code{vi} if neither is set.
+When editing is complete, the edited commands are echoed and executed.
+
+In the second form, @var{command} is re-executed after each instance
+of @var{pat} in the selected command is replaced by @var{rep}.
+@var{command} is interpreted the same as @var{first} above.
+
+A useful alias to use with the @code{fc} command is @code{r='fc -s'}, so
+that typing @samp{r cc} runs the last command beginning with @code{cc}
+and typing @samp{r} re-executes the last command (@pxref{Aliases}).
+
+@item history
+@btindex history
+@example
+history @var{n}
+history -c
+history -d @var{offset}
+history -d @var{start}-@var{end}
+history -anrw @var{filename}
+history -ps @var{arg}
+@end example
+
+With no options, display the history list with line numbers.
+Lines prefixed with a @samp{*} have been modified.
+An argument of @var{n} lists only the last @var{n} lines.
+If the shell variable @env{HISTTIMEFORMAT} is set and not null,
+it is used as a format string for @var{strftime} to display
+the time stamp associated with each displayed history entry.
+No intervening blank is printed between the formatted time stamp
+and the history line.
+
+Options, if supplied, have the following meanings:
+
+@table @code
+@item -c
+Clear the history list.  This may be combined
+with the other options to replace the history list completely.
+
+@item -d @var{offset}
+Delete the history entry at position @var{offset}.
+If @var{offset} is positive, it should be specified as it appears when
+the history is displayed.
+If @var{offset} is negative, it is interpreted as relative to one greater
+than the last history position, so negative indices count back from the
+end of the history, and an index of @samp{-1} refers to the current
+@code{history -d} command.
+
+@item -d @var{start}-@var{end}
+Delete the history entries between positions @var{start} and @var{end},
+inclusive.  Positive and negative values for @var{start} and @var{end}
+are interpreted as described above.
+
+@item -a
+Append the new history lines to the history file.
+These are history lines entered since the beginning of the current
+Bash session, but not already appended to the history file.
+
+@item -n
+Append the history lines not already read from the history file
+to the current history list.  These are lines appended to the history
+file since the beginning of the current Bash session.
+
+@item -r
+Read the history file and append its contents to
+the history list.
+
+@item -w
+Write out the current history list to the history file.
+
+@item -p
+Perform history substitution on the @var{arg}s and display the result
+on the standard output, without storing the results in the history list.
+
+@item -s
+The @var{arg}s are added to the end of
+the history list as a single entry.
+
+@end table
+
+When any of the @option{-w}, @option{-r}, @option{-a}, or @option{-n} options is
+used, if @var{filename}
+is given, then it is used as the history file.  If not, then
+the value of the @env{HISTFILE} variable is used.
+
+@end table
+@end ifset
+
+@node History Interaction
+@section History Expansion
+@cindex history expansion
+
+The History library provides a history expansion feature that is similar
+to the history expansion provided by @code{csh}.  This section
+describes the syntax used to manipulate the history information.
+
+History expansions introduce words from the history list into
+the input stream, making it easy to repeat commands, insert the
+arguments to a previous command into the current input line, or
+fix errors in previous commands quickly.
+
+@ifset BashFeatures
+History expansion is performed immediately after a complete line
+is read, before the shell breaks it into words, and is performed
+on each line individually.  Bash attempts to inform the history
+expansion functions about quoting still in effect from previous lines.
+@end ifset
+
+History expansion takes place in two parts.  The first is to determine
+which line from the history list should be used during substitution.
+The second is to select portions of that line for inclusion into the
+current one.  The line selected from the history is called the
+@dfn{event}, and the portions of that line that are acted upon are
+called @dfn{words}.  Various @dfn{modifiers} are available to manipulate
+the selected words.  The line is broken into words in the same fashion
+that Bash does, so that several words
+surrounded by quotes are considered one word.
+History expansions are introduced by the appearance of the
+history expansion character, which is @samp{!} by default.
+
+History expansion implements shell-like quoting conventions:
+a backslash can be used to remove the special handling for the next character;
+single quotes enclose verbatim sequences of characters, and can be used to
+inhibit history expansion;
+and characters enclosed within double quotes may be subject to history
+expansion, since backslash can escape the history expansion character,
+but single quotes may not, since they are not treated specially within
+double quotes.
+
+@ifset BashFeatures
+When using the shell, only @samp{\} and @samp{'} may be used to escape the
+history expansion character, but the history expansion character is
+also treated as quoted if it immediately precedes the closing double quote
+in a double-quoted string. 
+@end ifset
+
+@ifset BashFeatures
+Several shell options settable with the @code{shopt}
+builtin (@pxref{The Shopt Builtin}) may be used to tailor
+the behavior of history expansion.  If the
+@code{histverify} shell option is enabled, and Readline
+is being used, history substitutions are not immediately passed to
+the shell parser.
+Instead, the expanded line is reloaded into the Readline
+editing buffer for further modification.
+If Readline is being used, and the @code{histreedit}
+shell option is enabled, a failed history expansion will be
+reloaded into the Readline editing buffer for correction.
+The @option{-p} option to the @code{history} builtin command
+may be used to see what a history expansion will do before using it.
+The @option{-s} option to the @code{history} builtin may be used to
+add commands to the end of the history list without actually executing
+them, so that they are available for subsequent recall.
+This is most useful in conjunction with Readline.
+
+The shell allows control of the various characters used by the
+history expansion mechanism with the @code{histchars} variable,
+as explained above (@pxref{Bash Variables}).  The shell uses
+the history comment character to mark history timestamps when
+writing the history file.

+@node Event Designators
+@subsection Event Designators
+@cindex event designators
+
+An event designator is a reference to a command line entry in the
+history list.
+Unless the reference is absolute, events are relative to the current
+position in the history list.
+@cindex history events
+
+@table @asis
+
+@item @code{!}
+@ifset BashFeatures
+Start a history substitution, except when followed by a space, tab,
+the end of the line, @samp{=} or @samp{(} (when the
+@code{extglob} shell option is enabled using the @code{shopt} builtin).
+@end ifset
+@ifclear BashFeatures
+Start a history substitution, except when followed by a space, tab,
+the end of the line, or @samp{=}.
+@end ifclear
+
+@item @code{!@var{n}}
+Refer to command line @var{n}.
+
+@item @code{!-@var{n}}
+Refer to the command @var{n} lines back.
+
+@item @code{!!}
+Refer to the previous command.  This is a synonym for @samp{!-1}.
+
+@item @code{!@var{string}}
+Refer to the most recent command
+preceding the current position in the history list
+starting with @var{string}.
+
+@item @code{!?@var{string}?}
+Refer to the most recent command
+preceding the current position in the history list
+containing @var{string}.
+The trailing
+@samp{?} may be omitted if the @var{string} is followed immediately by
+a newline.
+If @var{string} is missing, the string from the most recent search is used;
+it is an error if there is no previous search string.
+
+@item @code{^@var{string1}^@var{string2}^}
+Quick Substitution.  Repeat the last command, replacing @var{string1}
+with @var{string2}.  Equivalent to
+@code{!!:s^@var{string1}^@var{string2}^}.
+
+@item @code{!#}
+The entire command line typed so far.
+
+@end table
+
+@node Word Designators
+@subsection Word Designators
+
+Word designators are used to select desired words from the event.
+A @samp{:} separates the event specification from the word designator.  It
+may be omitted if the word designator begins with a @samp{^}, @samp{$},
+@samp{*}, @samp{-}, or @samp{%}.  Words are numbered from the beginning
+of the line, with the first word being denoted by 0 (zero).  Words are
+inserted into the current line separated by single spaces.
+
+@need 0.75
+For example,
+
+@table @code
+@item !!
+designates the preceding command.  When you type this, the preceding
+command is repeated in toto.
+
+@item !!:$
+designates the last argument of the preceding command.  This may be
+shortened to @code{!$}.
+
+@item !fi:2
+designates the second argument of the most recent command starting with
+the letters @code{fi}.
+@end table
+
+@need 0.75
+Here are the word designators:
+ 
+@table @code
+
+@item 0 (zero)
+The @code{0}th word.  For many applications, this is the command word.
+
+@item @var{n}
+The @var{n}th word.
+
+@item ^
+The first argument; that is, word 1.
+
+@item $
+The last argument.
+
+@item %
+The first word matched by the most recent @samp{?@var{string}?} search,
+if the search string begins with a character that is part of a word.
+
+@item @var{x}-@var{y}
+A range of words; @samp{-@var{y}} abbreviates @samp{0-@var{y}}.
+
+@item *
+All of the words, except the @code{0}th.  This is a synonym for @samp{1-$}.
+It is not an error to use @samp{*} if there is just one word in the event;
+the empty string is returned in that case.
+
+@item @var{x}*
+Abbreviates @samp{@var{x}-$}
+
+@item @var{x}-
+Abbreviates @samp{@var{x}-$} like @samp{@var{x}*}, but omits the last word.
+If @samp{x} is missing, it defaults to 0.
+
+@end table
+
+If a word designator is supplied without an event specification, the
+previous command is used as the event.
+
+@node Modifiers
+@subsection Modifiers
+
+After the optional word designator, you can add a sequence of one or more
+of the following modifiers, each preceded by a @samp{:}.
+These modify, or edit, the word or words selected from the history event.
+
+@table @code
+
+@item h
+Remove a trailing pathname component, leaving only the head.
+
+@item t
+Remove all leading pathname components, leaving the tail.
+
+@item r
+Remove a trailing suffix of the form @samp{.@var{suffix}}, leaving
+the basename.
+
+@item e
+Remove all but the trailing suffix.
+
+@item p
+Print the new command but do not execute it.
+
+@ifset BashFeatures
+@item q
+Quote the substituted words, escaping further substitutions.
+
+@item x
+Quote the substituted words as with @samp{q},
+but break into words at spaces, tabs, and newlines.
+The @samp{q} and @samp{x} modifiers are mutually exclusive; the last one
+supplied is used.
+@end ifset
+
+@item s/@var{old}/@var{new}/
+Substitute @var{new} for the first occurrence of @var{old} in the
+event line.
+Any character may be used as the delimiter in place of @samp{/}.
+The delimiter may be quoted in @var{old} and @var{new}
+with a single backslash.  If @samp{&} appears in @var{new},
+it is replaced by @var{old}.  A single backslash will quote
+the @samp{&}.
+If @var{old} is null, it is set to the last @var{old}
+substituted, or, if no previous history substitutions took place,
+the last @var{string}
+in a !?@var{string}@code{?}
+search.
+If @var{new} is is null, each matching @var{old} is deleted.
+The final delimiter is optional if it is the last
+character on the input line.
+
+@item &
+Repeat the previous substitution.
+
+@item g
+@itemx a
+Cause changes to be applied over the entire event line.  Used in
+conjunction with @samp{s}, as in @code{gs/@var{old}/@var{new}/},
+or with @samp{&}.
+
+@item G
+Apply the following @samp{s} or @samp{&} modifier once to each word
+in the event.

+
+&#x1b;1mCOPYRIGHT&#x1b;0m
+ Readline is Copyright (C) 1989-2020 Free Software Foundation, Inc.
+
+&#x1b;1mDESCRIPTION&#x1b;0m
+ &#x1b;1mreadline &#x1b;22mwill read a line from the terminal and return it, using &#x1b;1mprompt&#x1b;0m
+ as a prompt. If &#x1b;1mprompt &#x1b;22mis &#x1b;1mNULL &#x1b;22mor the empty string, no prompt is is-
+ sued. The line returned is allocated with &#x1b;4mmalloc&#x1b;24m(3); the caller must
+ free it when finished. The line returned has the final newline re-
+ moved, so only the text of the line remains.
+
+ &#x1b;1mreadline &#x1b;22moffers editing capabilities while the user is entering the
+ line. By default, the line editing commands are similar to those of
+ emacs. A vi-style line editing interface is also available.
+
+ This manual page describes only the most basic use of &#x1b;1mreadline&#x1b;22m. Much
+ more functionality is available; see &#x1b;4mThe&#x1b;24m &#x1b;4mGNU&#x1b;24m &#x1b;4mReadline&#x1b;24m &#x1b;4mLibrary&#x1b;24m and &#x1b;4mThe&#x1b;0m
+ &#x1b;4mGNU&#x1b;24m &#x1b;4mHistory&#x1b;24m &#x1b;4mLibrary&#x1b;24m for additional information.
+
+&#x1b;1mRETURN VALUE&#x1b;0m
+ &#x1b;1mreadline &#x1b;22mreturns the text of the line read. A blank line returns the
+ empty string. If &#x1b;1mEOF &#x1b;22mis encountered while reading a line, and the line
+ is empty, &#x1b;1mNULL &#x1b;22mis returned. If an &#x1b;1mEOF &#x1b;22mis read with a non-empty line,
+ it is treated as a newline.
+
+&#x1b;1mNOTATION&#x1b;0m
+ An Emacs-style notation is used to denote keystrokes. Control keys are
+ denoted by C-&#x1b;4mkey&#x1b;24m, e.g., C-n means Control-N. Similarly, &#x1b;4mmeta&#x1b;24m keys are
+ denoted by M-&#x1b;4mkey&#x1b;24m, so M-x means Meta-X. (On keyboards without a &#x1b;4mmeta&#x1b;0m
+ key, M-&#x1b;4mx&#x1b;24m means ESC &#x1b;4mx&#x1b;24m, i.e., press the Escape key then the &#x1b;4mx&#x1b;24m key. This
+ makes ESC the &#x1b;4mmeta&#x1b;24m &#x1b;4mprefix&#x1b;24m. The combination M-C-&#x1b;4mx&#x1b;24m means ESC-Control-&#x1b;4mx&#x1b;24m,
+ or press the Escape key then hold the Control key while pressing the &#x1b;4mx&#x1b;0m
+ key.)
+
+ Readline commands may be given numeric &#x1b;4marguments&#x1b;24m, which normally act as
+ a repeat count. Sometimes, however, it is the sign of the argument
+ that is significant. Passing a negative argument to a command that
+ acts in the forward direction (e.g., &#x1b;1mkill-line&#x1b;22m) causes that command to
+ act in a backward direction. Commands whose behavior with arguments
+ deviates from this are noted below.
+
+ When a command is described as &#x1b;4mkilling&#x1b;24m text, the text deleted is saved
+ for possible future retrieval (&#x1b;4myanking&#x1b;24m). The killed text is saved in a
+ &#x1b;4mkill&#x1b;24m &#x1b;4mring&#x1b;24m. Consecutive kills cause the text to be accumulated into one
+ unit, which can be yanked all at once. Commands which do not kill text
+ separate the chunks of text on the kill ring.
+
+&#x1b;1mINITIALIZATION FILE&#x1b;0m
+ Readline is customized by putting commands in an initialization file
+ (the &#x1b;4minputrc&#x1b;24m file). The name of this file is taken from the value of
+ the &#x1b;1mINPUTRC &#x1b;22menvironment variable. If that variable is unset, the de-
+ fault is &#x1b;4m~/.inputrc&#x1b;24m. If that file does not exist or cannot be read,
+ the ultimate default is &#x1b;4m/etc/inputrc&#x1b;24m. When a program which uses the
+ readline library starts up, the init file is read, and the key bindings
+ and variables are set. There are only a few basic constructs allowed
+ in the readline init file. Blank lines are ignored. Lines beginning
+ with a &#x1b;1m# &#x1b;22mare comments. Lines beginning with a &#x1b;1m$ &#x1b;22mindicate conditional
+ constructs. Other lines denote key bindings and variable settings.
+ Each program using this library may add its own commands and bindings.
+
+ For example, placing
+
+ M-Control-u: universal-argument
+ or
+ C-Meta-u: universal-argument
+
+ into the &#x1b;4minputrc&#x1b;24m would make M-C-u execute the readline command &#x1b;4muniver-&#x1b;0m
+ &#x1b;4msal-argument&#x1b;24m.
+
+ The following symbolic character names are recognized while processing
+ key bindings: &#x1b;4mDEL&#x1b;24m, &#x1b;4mESC&#x1b;24m, &#x1b;4mESCAPE&#x1b;24m, &#x1b;4mLFD&#x1b;24m, &#x1b;4mNEWLINE&#x1b;24m, &#x1b;4mRET&#x1b;24m, &#x1b;4mRETURN&#x1b;24m, &#x1b;4mRUBOUT&#x1b;24m,
+ &#x1b;4mSPACE&#x1b;24m, &#x1b;4mSPC&#x1b;24m, and &#x1b;4mTAB&#x1b;24m.
+
+ In addition to command names, readline allows keys to be bound to a
+ string that is inserted when the key is pressed (a &#x1b;4mmacro&#x1b;24m).
+
+ &#x1b;1mKey Bindings&#x1b;0m
+ The syntax for controlling key bindings in the &#x1b;4minputrc&#x1b;24m file is simple.
+ All that is required is the name of the command or the text of a macro
+ and a key sequence to which it should be bound. The name may be speci-
+ fied in one of two ways: as a symbolic key name, possibly with &#x1b;4mMeta-&#x1b;24m or
+ &#x1b;4mControl-&#x1b;24m prefixes, or as a key sequence. The name and key sequence are
+ separated by a colon. There can be no whitespace between the name and
+ the colon.
+
+ When using the form &#x1b;1mkeyname&#x1b;22m:&#x1b;4mfunction-name&#x1b;24m or &#x1b;4mmacro&#x1b;24m, &#x1b;4mkeyname&#x1b;24m is the name
+ of a key spelled out in English. For example:
+
+ Control-u: universal-argument
+ Meta-Rubout: backward-kill-word
+ Control-o: "> output"
+
+ In the above example, &#x1b;4mC-u&#x1b;24m is bound to the function &#x1b;1muniversal-argument&#x1b;22m,
+ &#x1b;4mM-DEL&#x1b;24m is bound to the function &#x1b;1mbackward-kill-word&#x1b;22m, and &#x1b;4mC-o&#x1b;24m is bound to
+ run the macro expressed on the right hand side (that is, to insert the
+ text ``> output'' into the line).
+
+ In the second form, &#x1b;1m"keyseq"&#x1b;22m:&#x1b;4mfunction-name&#x1b;24m or &#x1b;4mmacro&#x1b;24m, &#x1b;1mkeyseq &#x1b;22mdiffers
+ from &#x1b;1mkeyname &#x1b;22mabove in that strings denoting an entire key sequence may
+ be specified by placing the sequence within double quotes. Some GNU
+ Emacs style key escapes can be used, as in the following example, but
+ the symbolic character names are not recognized.
+
+ "\C-u": universal-argument
+ "\C-x\C-r": re-read-init-file
+ "\e11~": "Function Key 1"
+
+ In this example, &#x1b;4mC-u&#x1b;24m is again bound to the function &#x1b;1muniversal-argument&#x1b;22m.
+ &#x1b;4mC-x&#x1b;24m &#x1b;4mC-r&#x1b;24m is bound to the function &#x1b;1mre-read-init-file&#x1b;22m, and &#x1b;4mESC&#x1b;24m &#x1b;4m&#x1b;24m &#x1b;4m1&#x1b;24m &#x1b;4m1&#x1b;24m &#x1b;4m~&#x1b;24m is
+ bound to insert the text ``Function Key 1''.
+
+ The full set of GNU Emacs style escape sequences available when speci-
+ fying key sequences is
+ &#x1b;1m\C- &#x1b;22mcontrol prefix
+ &#x1b;1m\M- &#x1b;22mmeta prefix
+ &#x1b;1m\e &#x1b;22man escape character
+ &#x1b;1m\\ &#x1b;22mbackslash
+ &#x1b;1m\" &#x1b;22mliteral ", a double quote
+ &#x1b;1m\' &#x1b;22mliteral ', a single quote
+
+ In addition to the GNU Emacs style escape sequences, a second set of
+ backslash escapes is available:
+ &#x1b;1m\a &#x1b;22malert (bell)
+ &#x1b;1m\b &#x1b;22mbackspace
+ &#x1b;1m\d &#x1b;22mdelete

+ &#x1b;1m\r &#x1b;22mcarriage return
+ &#x1b;1m\t &#x1b;22mhorizontal tab
+ &#x1b;1m\v &#x1b;22mvertical tab
+ &#x1b;1m\&#x1b;4m&#x1b;22mnnn&#x1b;24m the eight-bit character whose value is the octal value
+ &#x1b;4mnnn&#x1b;24m (one to three digits)
+ &#x1b;1m\x&#x1b;4m&#x1b;22mHH&#x1b;24m the eight-bit character whose value is the hexadecimal
+ value &#x1b;4mHH&#x1b;24m (one or two hex digits)
+
+ When entering the text of a macro, single or double quotes should be
+ used to indicate a macro definition. Unquoted text is assumed to be a
+ function name. In the macro body, the backslash escapes described
+ above are expanded. Backslash will quote any other character in the
+ macro text, including " and '.
+
+ &#x1b;1mBash &#x1b;22mallows the current readline key bindings to be displayed or modi-
+ fied with the &#x1b;1mbind &#x1b;22mbuiltin command. The editing mode may be switched
+ during interactive use by using the &#x1b;1m-o &#x1b;22moption to the &#x1b;1mset &#x1b;22mbuiltin com-
+ mand. Other programs using this library provide similar mechanisms.
+ The &#x1b;4minputrc&#x1b;24m file may be edited and re-read if a program does not pro-
+ vide any other means to incorporate new bindings.
+
+ &#x1b;1mVariables&#x1b;0m
+ Readline has variables that can be used to further customize its behav-
+ ior. A variable may be set in the &#x1b;4minputrc&#x1b;24m file with a statement of the
+ form
+
+ &#x1b;1mset &#x1b;4m&#x1b;22mvariable-name&#x1b;24m &#x1b;4mvalue&#x1b;0m
+
+ Except where noted, readline variables can take the values &#x1b;1mOn &#x1b;22mor &#x1b;1mOff&#x1b;0m
+ (without regard to case). Unrecognized variable names are ignored.
+ When a variable value is read, empty or null values, "on" (case-insen-
+ sitive), and "1" are equivalent to &#x1b;1mOn&#x1b;22m. All other values are equivalent
+ to &#x1b;1mOff&#x1b;22m. The variables and their default values are:
+
+ &#x1b;1mbell-style (audible)&#x1b;0m
+ Controls what happens when readline wants to ring the terminal
+ bell. If set to &#x1b;1mnone&#x1b;22m, readline never rings the bell. If set to
+ &#x1b;1mvisible&#x1b;22m, readline uses a visible bell if one is available. If
+ set to &#x1b;1maudible&#x1b;22m, readline attempts to ring the terminal's bell.
+ &#x1b;1mbind-tty-special-chars (On)&#x1b;0m
+ If set to &#x1b;1mOn &#x1b;22m(the default), readline attempts to bind the con-
+ trol characters treated specially by the kernel's terminal
+ driver to their readline equivalents.
+ &#x1b;1mblink-matching-paren (Off)&#x1b;0m
+ If set to &#x1b;1mOn&#x1b;22m, readline attempts to briefly move the cursor to an
+ opening parenthesis when a closing parenthesis is inserted.
+ &#x1b;1mcolored-completion-prefix (Off)&#x1b;0m
+ If set to &#x1b;1mOn&#x1b;22m, when listing completions, readline displays the
+ common prefix of the set of possible completions using a differ-
+ ent color. The color definitions are taken from the value of
+ the &#x1b;1mLS_COLORS &#x1b;22menvironment variable.
+ &#x1b;1mcolored-stats (Off)&#x1b;0m
+ If set to &#x1b;1mOn&#x1b;22m, readline displays possible completions using dif-
+ ferent colors to indicate their file type. The color defini-
+ tions are taken from the value of the &#x1b;1mLS_COLORS &#x1b;22menvironment
+ variable.
+ &#x1b;1mcomment-begin (``#'')&#x1b;0m
+ The string that is inserted in &#x1b;1mvi &#x1b;22mmode when the &#x1b;1minsert-comment&#x1b;0m
+ command is executed. This command is bound to &#x1b;1mM-# &#x1b;22min emacs mode
+ and to &#x1b;1m# &#x1b;22min vi command mode.
+ &#x1b;1mcompletion-display-width (-1)&#x1b;0m
+ The number of screen columns used to display possible matches
+ when performing completion. The value is ignored if it is less
+ than 0 or greater than the terminal screen width. A value of 0
+ will cause matches to be displayed one per line. The default
+ value is -1.
+ &#x1b;1mcompletion-ignore-case (Off)&#x1b;0m
+ If set to &#x1b;1mOn&#x1b;22m, readline performs filename matching and completion
+ in a case-insensitive fashion.
+ &#x1b;1mcompletion-map-case (Off)&#x1b;0m
+ If set to &#x1b;1mOn&#x1b;22m, and &#x1b;1mcompletion-ignore-case &#x1b;22mis enabled, readline
+ treats hyphens (&#x1b;4m-&#x1b;24m) and underscores (&#x1b;4m_&#x1b;24m) as equivalent when per-
+ forming case-insensitive filename matching and completion.
+ &#x1b;1mcompletion-prefix-display-length (0)&#x1b;0m
+ The length in characters of the common prefix of a list of pos-
+ sible completions that is displayed without modification. When
+ set to a value greater than zero, common prefixes longer than
+ this value are replaced with an ellipsis when displaying possi-
+ ble completions.
+ &#x1b;1mcompletion-query-items (100)&#x1b;0m
+ This determines when the user is queried about viewing the num-
+ ber of possible completions generated by the &#x1b;1mpossible-comple-&#x1b;0m
+ &#x1b;1mtions &#x1b;22mcommand. It may be set to any integer value greater than
+ or equal to zero. If the number of possible completions is
+ greater than or equal to the value of this variable, readline
+ will ask whether or not the user wishes to view them; otherwise
+ they are simply listed on the terminal. A negative value causes
+ readline to never ask.
+ &#x1b;1mconvert-meta (On)&#x1b;0m
+ If set to &#x1b;1mOn&#x1b;22m, readline will convert characters with the eighth
+ bit set to an ASCII key sequence by stripping the eighth bit and
+ prefixing it with an escape character (in effect, using escape
+ as the &#x1b;4mmeta&#x1b;24m &#x1b;4mprefix&#x1b;24m). The default is &#x1b;4mOn&#x1b;24m, but readline will set
+ it to &#x1b;4mOff&#x1b;24m if the locale contains eight-bit characters.
+ &#x1b;1mdisable-completion (Off)&#x1b;0m
+ If set to &#x1b;1mOn&#x1b;22m, readline will inhibit word completion. Completion
+ characters will be inserted into the line as if they had been
+ mapped to &#x1b;1mself-insert&#x1b;22m.
+ &#x1b;1mecho-control-characters (On)&#x1b;0m
+ When set to &#x1b;1mOn&#x1b;22m, on operating systems that indicate they support
+ it, readline echoes a character corresponding to a signal gener-
+ ated from the keyboard.
+ &#x1b;1mediting-mode (emacs)&#x1b;0m
+ Controls whether readline begins with a set of key bindings sim-
+ ilar to &#x1b;4mEmacs&#x1b;24m or &#x1b;4mvi&#x1b;24m. &#x1b;1mediting-mode &#x1b;22mcan be set to either &#x1b;1memacs &#x1b;22mor
+ &#x1b;1mvi&#x1b;22m.
+ &#x1b;1memacs-mode-string (@)&#x1b;0m
+ If the &#x1b;4mshow-mode-in-prompt&#x1b;24m variable is enabled, this string is
+ displayed immediately before the last line of the primary prompt
+ when emacs editing mode is active. The value is expanded like a
+ key binding, so the standard set of meta- and control prefixes
+ and backslash escape sequences is available. Use the \1 and \2
+ escapes to begin and end sequences of non-printing characters,
+ which can be used to embed a terminal control sequence into the
+ mode string.
+ &#x1b;1menable-bracketed-paste (On)&#x1b;0m
+ When set to &#x1b;1mOn&#x1b;22m, readline will configure the terminal in a way
+ that will enable it to insert each paste into the editing buffer
+ as a single string of characters, instead of treating each char-
+ acter as if it had been read from the keyboard. This can pre-
+ vent pasted characters from being interpreted as editing com-
+ mands.
+ &#x1b;1menable-keypad (Off)&#x1b;0m
+ When set to &#x1b;1mOn&#x1b;22m, readline will try to enable the application key-
+ pad when it is called. Some systems need this to enable the ar-
+ row keys.
+ &#x1b;1menable-meta-key (On)&#x1b;0m
+ When set to &#x1b;1mOn&#x1b;22m, readline will try to enable any meta modifier
+ key the terminal claims to support when it is called. On many
+ terminals, the meta key is used to send eight-bit characters.
+ &#x1b;1mexpand-tilde (Off)&#x1b;0m
+ If set to &#x1b;1mOn&#x1b;22m, tilde expansion is performed when readline at-
+ tempts word completion.
+ &#x1b;1mhistory-preserve-point (Off)&#x1b;0m
+ If set to &#x1b;1mOn&#x1b;22m, the history code attempts to place point at the
+ same location on each history line retrieved with &#x1b;1mprevious-his-&#x1b;0m
+ &#x1b;1mtory &#x1b;22mor &#x1b;1mnext-history&#x1b;22m.
+ &#x1b;1mhistory-size (unset)&#x1b;0m
+ Set the maximum number of history entries saved in the history
+ list. If set to zero, any existing history entries are deleted
+ and no new entries are saved. If set to a value less than zero,
+ the number of history entries is not limited. By default, the
+ number of history entries is not limited. If an attempt is made
+ to set &#x1b;4mhistory-size&#x1b;24m to a non-numeric value, the maximum number
+ of history entries will be set to 500.
+ &#x1b;1mhorizontal-scroll-mode (Off)&#x1b;0m
+ When set to &#x1b;1mOn&#x1b;22m, makes readline use a single line for display,
+ scrolling the input horizontally on a single screen line when it
+ becomes longer than the screen width rather than wrapping to a
+ new line. This setting is automatically enabled for terminals
+ of height 1.
+ &#x1b;1minput-meta (Off)&#x1b;0m
+ If set to &#x1b;1mOn&#x1b;22m, readline will enable eight-bit input (that is, it
+ will not clear the eighth bit in the characters it reads), re-
+ gardless of what the terminal claims it can support. The name
+ &#x1b;1mmeta-flag &#x1b;22mis a synonym for this variable. The default is &#x1b;4mOff&#x1b;24m,
+ but readline will set it to &#x1b;4mOn&#x1b;24m if the locale contains eight-bit
+ characters.
+ &#x1b;1misearch-terminators (``C- C-J'')&#x1b;0m
+ The string of characters that should terminate an incremental
+ search without subsequently executing the character as a com-
+ mand. If this variable has not been given a value, the charac-
+ ters &#x1b;4mESC&#x1b;24m and &#x1b;4mC-J&#x1b;24m will terminate an incremental search.
+ &#x1b;1mkeymap (emacs)&#x1b;0m
+ Set the current readline keymap. The set of legal keymap names
+ is &#x1b;4memacs,&#x1b;24m &#x1b;4memacs-standard,&#x1b;24m &#x1b;4memacs-meta,&#x1b;24m &#x1b;4memacs-ctlx,&#x1b;24m &#x1b;4mvi,&#x1b;24m &#x1b;4mvi-move,&#x1b;0m
+ &#x1b;4mvi-command&#x1b;24m, and &#x1b;4mvi-insert&#x1b;24m. &#x1b;4mvi&#x1b;24m is equivalent to &#x1b;4mvi-command&#x1b;24m;
+ &#x1b;4memacs&#x1b;24m is equivalent to &#x1b;4memacs-standard&#x1b;24m. The default value is
+ &#x1b;4memacs&#x1b;24m. The value of &#x1b;1mediting-mode &#x1b;22malso affects the default
+ keymap.
+ &#x1b;1mkeyseq-timeout (500)&#x1b;0m
+ Specifies the duration &#x1b;4mreadline&#x1b;24m will wait for a character when
+ reading an ambiguous key sequence (one that can form a complete
+ key sequence using the input read so far, or can take additional
+ input to complete a longer key sequence). If no input is re-
+ ceived within the timeout, &#x1b;4mreadline&#x1b;24m will use the shorter but
+ complete key sequence. The value is specified in milliseconds,
+ so a value of 1000 means that &#x1b;4mreadline&#x1b;24m will wait one second for
+ additional input. If this variable is set to a value less than
+ or equal to zero, or to a non-numeric value, &#x1b;4mreadline&#x1b;24m will wait
+ until another key is pressed to decide which key sequence to
+ complete.
+ &#x1b;1mmark-directories (On)&#x1b;0m
+ If set to &#x1b;1mOn&#x1b;22m, completed directory names have a slash appended.
+ &#x1b;1mmark-modified-lines (Off)&#x1b;0m
+ If set to &#x1b;1mOn&#x1b;22m, history lines that have been modified are dis-
+ played with a preceding asterisk (&#x1b;1m*&#x1b;22m).
+ &#x1b;1mmark-symlinked-directories (Off)&#x1b;0m
+ If set to &#x1b;1mOn&#x1b;22m, completed names which are symbolic links to direc-
+ tories have a slash appended (subject to the value of &#x1b;1mmark-di-&#x1b;0m
+ &#x1b;1mrectories&#x1b;22m).
+ &#x1b;1mmatch-hidden-files (On)&#x1b;0m
+ This variable, when set to &#x1b;1mOn&#x1b;22m, causes readline to match files
+ whose names begin with a `.' (hidden files) when performing
+ filename completion. If set to &#x1b;1mOff&#x1b;22m, the leading `.' must be
+ supplied by the user in the filename to be completed.
+ &#x1b;1mmenu-complete-display-prefix (Off)&#x1b;0m
+ If set to &#x1b;1mOn&#x1b;22m, menu completion displays the common prefix of the
+ list of possible completions (which may be empty) before cycling
+ through the list.
+ &#x1b;1moutput-meta (Off)&#x1b;0m
+ If set to &#x1b;1mOn&#x1b;22m, readline will display characters with the eighth
+ bit set directly rather than as a meta-prefixed escape sequence.
+ The default is &#x1b;4mOff&#x1b;24m, but readline will set it to &#x1b;4mOn&#x1b;24m if the locale
+ contains eight-bit characters.
+ &#x1b;1mpage-completions (On)&#x1b;0m
+ If set to &#x1b;1mOn&#x1b;22m, readline uses an internal &#x1b;4mmore&#x1b;24m-like pager to dis-
+ play a screenful of possible completions at a time.
+ &#x1b;1mprint-completions-horizontally (Off)&#x1b;0m
+ If set to &#x1b;1mOn&#x1b;22m, readline will display completions with matches
+ sorted horizontally in alphabetical order, rather than down the
+ screen.
+ &#x1b;1mrevert-all-at-newline (Off)&#x1b;0m
+ If set to &#x1b;1mOn&#x1b;22m, readline will undo all changes to history lines
+ before returning when &#x1b;1maccept-line &#x1b;22mis executed. By default, his-
+ tory lines may be modified and retain individual undo lists
+ across calls to &#x1b;1mreadline&#x1b;22m.
+ &#x1b;1mshow-all-if-ambiguous (Off)&#x1b;0m
+ This alters the default behavior of the completion functions.
+ If set to &#x1b;1mOn&#x1b;22m, words which have more than one possible completion
+ cause the matches to be listed immediately instead of ringing
+ the bell.
+ &#x1b;1mshow-all-if-unmodified (Off)&#x1b;0m
+ This alters the default behavior of the completion functions in
+ a fashion similar to &#x1b;1mshow-all-if-ambiguous&#x1b;22m. If set to &#x1b;1mOn&#x1b;22m, words
+ which have more than one possible completion without any possi-
+ ble partial completion (the possible completions don't share a
+ common prefix) cause the matches to be listed immediately in-
+ stead of ringing the bell.
+ &#x1b;1mshow-mode-in-prompt (Off)&#x1b;0m
+ If set to &#x1b;1mOn&#x1b;22m, add a string to the beginning of the prompt indi-
+ cating the editing mode: emacs, vi command, or vi insertion.
+ The mode strings are user-settable (e.g., &#x1b;4memacs-mode-string&#x1b;24m).
+ &#x1b;1mskip-completed-text (Off)&#x1b;0m
+ If set to &#x1b;1mOn&#x1b;22m, this alters the default completion behavior when
+ inserting a single match into the line. It's only active when
+ performing completion in the middle of a word. If enabled,
+ readline does not insert characters from the completion that
+ match characters after point in the word being completed, so
+ portions of the word following the cursor are not duplicated.
+ &#x1b;1mvi-cmd-mode-string ((cmd))&#x1b;0m
+ If the &#x1b;4mshow-mode-in-prompt&#x1b;24m variable is enabled, this string is
+ displayed immediately before the last line of the primary prompt
+ when vi editing mode is active and in command mode. The value
+ is expanded like a key binding, so the standard set of meta- and
+ control prefixes and backslash escape sequences is available.
+ Use the \1 and \2 escapes to begin and end sequences of non-
+ printing characters, which can be used to embed a terminal con-
+ trol sequence into the mode string.
+ &#x1b;1mvi-ins-mode-string ((ins))&#x1b;0m
+ If the &#x1b;4mshow-mode-in-prompt&#x1b;24m variable is enabled, this string is
+ displayed immediately before the last line of the primary prompt
+ when vi editing mode is active and in insertion mode. The value
+ is expanded like a key binding, so the standard set of meta- and
+ control prefixes and backslash escape sequences is available.
+ Use the \1 and \2 escapes to begin and end sequences of non-
+ printing characters, which can be used to embed a terminal con-
+ trol sequence into the mode string.
+ &#x1b;1mvisible-stats (Off)&#x1b;0m
+ If set to &#x1b;1mOn&#x1b;22m, a character denoting a file's type as reported by
+ &#x1b;4mstat&#x1b;24m(2) is appended to the filename when listing possible com-
+ pletions.
+
+ &#x1b;1mConditional Constructs&#x1b;0m
+ Readline implements a facility similar in spirit to the conditional
+ compilation features of the C preprocessor which allows key bindings
+ and variable settings to be performed as the result of tests. There
+ are four parser directives used.
+
+ &#x1b;1m$if &#x1b;22mThe &#x1b;1m$if &#x1b;22mconstruct allows bindings to be made based on the edit-
+ ing mode, the terminal being used, or the application using
+ readline. The text of the test, after any comparison operator,
+ extends to the end of the line; unless otherwise noted, no char-
+ acters are required to isolate it.
+
+ &#x1b;1mmode &#x1b;22mThe &#x1b;1mmode= &#x1b;22mform of the &#x1b;1m$if &#x1b;22mdirective is used to test
+ whether readline is in emacs or vi mode. This may be
+ used in conjunction with the &#x1b;1mset keymap &#x1b;22mcommand, for in-
+ stance, to set bindings in the &#x1b;4memacs-standard&#x1b;24m and &#x1b;4memacs-&#x1b;0m
+ &#x1b;4mctlx&#x1b;24m keymaps only if readline is starting out in emacs
+ mode.
+
+ &#x1b;1mterm &#x1b;22mThe &#x1b;1mterm= &#x1b;22mform may be used to include terminal-specific
+ key bindings, perhaps to bind the key sequences output by
+ the terminal's function keys. The word on the right side
+ of the &#x1b;1m= &#x1b;22mis tested against the full name of the terminal
+ and the portion of the terminal name before the first &#x1b;1m-&#x1b;22m.
+ This allows &#x1b;4msun&#x1b;24m to match both &#x1b;4msun&#x1b;24m and &#x1b;4msun-cmd&#x1b;24m, for in-
+ stance.
+
+ &#x1b;1mversion&#x1b;0m
+ The &#x1b;1mversion &#x1b;22mtest may be used to perform comparisons
+ against specific readline versions. The &#x1b;1mversion &#x1b;22mexpands
+ to the current readline version. The set of comparison
+ operators includes &#x1b;1m=&#x1b;22m, (and &#x1b;1m==&#x1b;22m), &#x1b;1m!=&#x1b;22m, &#x1b;1m<=&#x1b;22m, &#x1b;1m>=&#x1b;22m, &#x1b;1m<&#x1b;22m, and &#x1b;1m>&#x1b;22m.
+ The version number supplied on the right side of the op-
+ erator consists of a major version number, an optional
+ decimal point, and an optional minor version (e.g., &#x1b;1m7.1&#x1b;22m).
+ If the minor version is omitted, it is assumed to be &#x1b;1m0&#x1b;22m.
+ The operator may be separated from the string &#x1b;1mversion &#x1b;22mand
+ from the version number argument by whitespace.
+
+ &#x1b;1mapplication&#x1b;0m
+ The &#x1b;1mapplication &#x1b;22mconstruct is used to include application-
+ specific settings. Each program using the readline li-
+ brary sets the &#x1b;4mapplication&#x1b;24m &#x1b;4mname&#x1b;24m, and an initialization
+ file can test for a particular value. This could be used
+ to bind key sequences to functions useful for a specific
+ program. For instance, the following command adds a key
+ sequence that quotes the current or previous word in
+ &#x1b;1mbash&#x1b;22m:
+
+ &#x1b;1m$if &#x1b;22mBash
+ # Quote the current or previous word
+ "\C-xq": "\eb\"\ef\""
+ &#x1b;1m$endif&#x1b;0m
+
+ &#x1b;4mvariable&#x1b;0m
+ The &#x1b;4mvariable&#x1b;24m construct provides simple equality tests for
+ readline variables and values. The permitted comparison
+ operators are &#x1b;4m=&#x1b;24m, &#x1b;4m==&#x1b;24m, and &#x1b;4m!=&#x1b;24m. The variable name must be
+ separated from the comparison operator by whitespace; the
+ operator may be separated from the value on the right
+ hand side by whitespace. Both string and boolean vari-
+ ables may be tested. Boolean variables must be tested
+ against the values &#x1b;4mon&#x1b;24m and &#x1b;4moff&#x1b;24m.
+
+ &#x1b;1m$endif &#x1b;22mThis command, as seen in the previous example, terminates an &#x1b;1m$if&#x1b;0m
+ command.
+
+ &#x1b;1m$else &#x1b;22mCommands in this branch of the &#x1b;1m$if &#x1b;22mdirective are executed if the
+ test fails.
+
+ &#x1b;1m$include&#x1b;0m
+ This directive takes a single filename as an argument and reads
+ commands and bindings from that file. For example, the follow-
+ ing directive would read &#x1b;4m/etc/inputrc&#x1b;24m:
+
+ &#x1b;1m$include &#x1b;4m&#x1b;22m/etc/inputrc&#x1b;0m
+
+&#x1b;1mSEARCHING&#x1b;0m
+ Readline provides commands for searching through the command history
+ for lines containing a specified string. There are two search modes:
+ &#x1b;4mincremental&#x1b;24m and &#x1b;4mnon-incremental&#x1b;24m.
+
+ Incremental searches begin before the user has finished typing the
+ search string. As each character of the search string is typed, read-
+ line displays the next entry from the history matching the string typed
+ so far. An incremental search requires only as many characters as
+ needed to find the desired history entry. To search backward in the
+ history for a particular string, type &#x1b;1mC-r&#x1b;22m. Typing &#x1b;1mC-s &#x1b;22msearches forward
+ through the history. The characters present in the value of the
+ &#x1b;1misearch-terminators &#x1b;22mvariable are used to terminate an incremental
+ search. If that variable has not been assigned a value the &#x1b;4mEscape&#x1b;24m and
+ &#x1b;1mC-J &#x1b;22mcharacters will terminate an incremental search. &#x1b;1mC-G &#x1b;22mwill abort an
+ incremental search and restore the original line. When the search is
+ terminated, the history entry containing the search string becomes the
+ current line.
+
+ To find other matching entries in the history list, type &#x1b;1mC-s &#x1b;22mor &#x1b;1mC-r &#x1b;22mas
+ appropriate. This will search backward or forward in the history for
+ the next line matching the search string typed so far. Any other key
+ sequence bound to a readline command will terminate the search and exe-
+ cute that command. For instance, a newline will terminate the search
+ and accept the line, thereby executing the command from the history
+ list. A movement command will terminate the search, make the last line
+ found the current line, and begin editing.
+
+ Non-incremental searches read the entire search string before starting
+ to search for matching history lines. The search string may be typed
+ by the user or be part of the contents of the current line.
+
+&#x1b;1mEDITING COMMANDS&#x1b;0m
+ The following is a list of the names of the commands and the default
+ key sequences to which they are bound. Command names without an accom-
+ panying key sequence are unbound by default.
+
+ In the following descriptions, &#x1b;4mpoint&#x1b;24m refers to the current cursor posi-
+ tion, and &#x1b;4mmark&#x1b;24m refers to a cursor position saved by the &#x1b;1mset-mark &#x1b;22mcom-
+ mand. The text between the point and mark is referred to as the &#x1b;4mre-&#x1b;0m
+ &#x1b;4mgion&#x1b;24m.
+
+ &#x1b;1mCommands for Moving&#x1b;0m
+ &#x1b;1mbeginning-of-line (C-a)&#x1b;0m
+ Move to the start of the current line.
+ &#x1b;1mend-of-line (C-e)&#x1b;0m
+ Move to the end of the line.
+ &#x1b;1mforward-char (C-f)&#x1b;0m
+ Move forward a character.
+ &#x1b;1mbackward-char (C-b)&#x1b;0m
+ Move back a character.
+ &#x1b;1mforward-word (M-f)&#x1b;0m
+ Move forward to the end of the next word. Words are composed of
+ alphanumeric characters (letters and digits).
+ &#x1b;1mbackward-word (M-b)&#x1b;0m
+ Move back to the start of the current or previous word. Words
+ are composed of alphanumeric characters (letters and digits).
+ &#x1b;1mprevious-screen-line&#x1b;0m
+ Attempt to move point to the same physical screen column on the
+ previous physical screen line. This will not have the desired
+ effect if the current Readline line does not take up more than
+ one physical line or if point is not greater than the length of
+ the prompt plus the screen width.
+ &#x1b;1mnext-screen-line&#x1b;0m
+ Attempt to move point to the same physical screen column on the
+ next physical screen line. This will not have the desired effect
+ if the current Readline line does not take up more than one
+ physical line or if the length of the current Readline line is
+ not greater than the length of the prompt plus the screen width.
+ &#x1b;1mclear-display (M-C-l)&#x1b;0m
+ Clear the screen and, if possible, the terminal's scrollback
+ buffer, then redraw the current line, leaving the current line
+ at the top of the screen.
+ &#x1b;1mclear-screen (C-l)&#x1b;0m
+ Clear the screen, then redraw the current line, leaving the cur-
+ rent line at the top of the screen. With an argument, refresh
+ the current line without clearing the screen.
+ &#x1b;1mredraw-current-line&#x1b;0m
+ Refresh the current line.
+
+ &#x1b;1mCommands for Manipulating the History&#x1b;0m
+ &#x1b;1maccept-line (Newline, Return)&#x1b;0m
+ Accept the line regardless of where the cursor is. If this line
+ is non-empty, it may be added to the history list for future re-
+ call with &#x1b;1madd_history()&#x1b;22m. If the line is a modified history
+ line, the history line is restored to its original state.
+ &#x1b;1mprevious-history (C-p)&#x1b;0m
+ Fetch the previous command from the history list, moving back in
+ the list.
+ &#x1b;1mnext-history (C-n)&#x1b;0m
+ Fetch the next command from the history list, moving forward in
+ the list.
+ &#x1b;1mbeginning-of-history (M-<)&#x1b;0m
+ Move to the first line in the history.
+ &#x1b;1mend-of-history (M->)&#x1b;0m
+ Move to the end of the input history, i.e., the line currently
+ being entered.
+ &#x1b;1mreverse-search-history (C-r)&#x1b;0m
+ Search backward starting at the current line and moving `up'
+ through the history as necessary. This is an incremental
+ search.
+ &#x1b;1mforward-search-history (C-s)&#x1b;0m
+ Search forward starting at the current line and moving `down'
+ through the history as necessary. This is an incremental
+ search.
+ &#x1b;1mnon-incremental-reverse-search-history (M-p)&#x1b;0m
+ Search backward through the history starting at the current line
+ using a non-incremental search for a string supplied by the
+ user.
+ &#x1b;1mnon-incremental-forward-search-history (M-n)&#x1b;0m
+ Search forward through the history using a non-incremental
+ search for a string supplied by the user.
+ &#x1b;1mhistory-search-backward&#x1b;0m
+ Search backward through the history for the string of characters
+ between the start of the current line and the current cursor po-
+ sition (the &#x1b;4mpoint&#x1b;24m). The search string must match at the begin-
+ ning of a history line. This is a non-incremental search.
+ &#x1b;1mhistory-search-forward&#x1b;0m
+ Search forward through the history for the string of characters
+ between the start of the current line and the point. The search
+ string must match at the beginning of a history line. This is a
+ non-incremental search.
+ &#x1b;1mhistory-substring-search-backward&#x1b;0m
+ Search backward through the history for the string of characters
+ between the start of the current line and the current cursor po-
+ sition (the &#x1b;4mpoint&#x1b;24m). The search string may match anywhere in a
+ history line. This is a non-incremental search.
+ &#x1b;1mhistory-substring-search-forward&#x1b;0m
+ Search forward through the history for the string of characters
+ between the start of the current line and the point. The search
+ string may match anywhere in a history line. This is a non-in-
+ cremental search.
+ &#x1b;1myank-nth-arg (M-C-y)&#x1b;0m
+ Insert the first argument to the previous command (usually the
+ second word on the previous line) at point. With an argument &#x1b;4mn&#x1b;24m,
+ insert the &#x1b;4mn&#x1b;24mth word from the previous command (the words in the
+ previous command begin with word 0). A negative argument in-
+ serts the &#x1b;4mn&#x1b;24mth word from the end of the previous command. Once
+ the argument &#x1b;4mn&#x1b;24m is computed, the argument is extracted as if the
+ "!&#x1b;4mn&#x1b;24m" history expansion had been specified.
+ &#x1b;1myank-last-arg (M-., M-_)&#x1b;0m
+ Insert the last argument to the previous command (the last word
+ of the previous history entry). With a numeric argument, behave
+ exactly like &#x1b;1myank-nth-arg&#x1b;22m. Successive calls to &#x1b;1myank-last-arg&#x1b;0m
+ move back through the history list, inserting the last word (or
+ the word specified by the argument to the first call) of each
+ line in turn. Any numeric argument supplied to these successive
+ calls determines the direction to move through the history. A
+ negative argument switches the direction through the history
+ (back or forward). The history expansion facilities are used to
+ extract the last argument, as if the "!$" history expansion had
+ been specified.
+ &#x1b;1moperate-and-get-next (C-o)&#x1b;0m
+ Accept the current line for return to the calling application as
+ if a newline had been entered, and fetch the next line relative
+ to the current line from the history for editing. A numeric ar-
+ gument, if supplied, specifies the history entry to use instead
+ of the current line.
+
+ &#x1b;1mCommands for Changing Text&#x1b;0m
+ &#x1b;4mend-of-file&#x1b;24m &#x1b;1m(usually C-d)&#x1b;0m
+ The character indicating end-of-file as set, for example, by
+ ``stty''. If this character is read when there are no charac-
+ ters on the line, and point is at the beginning of the line,
+ Readline interprets it as the end of input and returns &#x1b;1mEOF&#x1b;22m.
+ &#x1b;1mdelete-char (C-d)&#x1b;0m
+ Delete the character at point. If this function is bound to the
+ same character as the tty &#x1b;1mEOF &#x1b;22mcharacter, as &#x1b;1mC-d &#x1b;22mcommonly is, see
+ above for the effects.
+ &#x1b;1mbackward-delete-char (Rubout)&#x1b;0m
+ Delete the character behind the cursor. When given a numeric
+ argument, save the deleted text on the kill ring.
+ &#x1b;1mforward-backward-delete-char&#x1b;0m
+ Delete the character under the cursor, unless the cursor is at
+ the end of the line, in which case the character behind the cur-
+ sor is deleted.
+ &#x1b;1mquoted-insert (C-q, C-v)&#x1b;0m
+ Add the next character that you type to the line verbatim. This
+ is how to insert characters like &#x1b;1mC-q&#x1b;22m, for example.
+ &#x1b;1mtab-insert (M-TAB)&#x1b;0m
+ Insert a tab character.
+ &#x1b;1mself-insert (a, b, A, 1, !, ...)&#x1b;0m
+ Insert the character typed.
+ &#x1b;1mtranspose-chars (C-t)&#x1b;0m
+ Drag the character before point forward over the character at
+ point, moving point forward as well. If point is at the end of
+ the line, then this transposes the two characters before point.
+ Negative arguments have no effect.
+ &#x1b;1mtranspose-words (M-t)&#x1b;0m
+ Drag the word before point past the word after point, moving
+ point over that word as well. If point is at the end of the
+ line, this transposes the last two words on the line.
+ &#x1b;1mupcase-word (M-u)&#x1b;0m
+ Uppercase the current (or following) word. With a negative ar-
+ gument, uppercase the previous word, but do not move point.
+ &#x1b;1mdowncase-word (M-l)&#x1b;0m
+ Lowercase the current (or following) word. With a negative ar-
+ gument, lowercase the previous word, but do not move point.
+ &#x1b;1mcapitalize-word (M-c)&#x1b;0m
+ Capitalize the current (or following) word. With a negative ar-
+ gument, capitalize the previous word, but do not move point.
+ &#x1b;1moverwrite-mode&#x1b;0m
+ Toggle overwrite mode. With an explicit positive numeric argu-
+ ment, switches to overwrite mode. With an explicit non-positive
+ numeric argument, switches to insert mode. This command affects
+ only &#x1b;1memacs &#x1b;22mmode; &#x1b;1mvi &#x1b;22mmode does overwrite differently. Each call
+ to &#x1b;4mreadline()&#x1b;24m starts in insert mode. In overwrite mode, charac-
+ ters bound to &#x1b;1mself-insert &#x1b;22mreplace the text at point rather than
+ pushing the text to the right. Characters bound to &#x1b;1mback-&#x1b;0m
+ &#x1b;1mward-delete-char &#x1b;22mreplace the character before point with a
+ space. By default, this command is unbound.
+
+ &#x1b;1mKilling and Yanking&#x1b;0m
+ &#x1b;1mkill-line (C-k)&#x1b;0m
+ Kill the text from point to the end of the line.
+ &#x1b;1mbackward-kill-line (C-x Rubout)&#x1b;0m
+ Kill backward to the beginning of the line.
+ &#x1b;1munix-line-discard (C-u)&#x1b;0m
+ Kill backward from point to the beginning of the line. The
+ killed text is saved on the kill-ring.
+ &#x1b;1mkill-whole-line&#x1b;0m
+ Kill all characters on the current line, no matter where point
+ is.
+ &#x1b;1mkill-word (M-d)&#x1b;0m
+ Kill from point the end of the current word, or if between
+ words, to the end of the next word. Word boundaries are the
+ same as those used by &#x1b;1mforward-word&#x1b;22m.
+ &#x1b;1mbackward-kill-word (M-Rubout)&#x1b;0m
+ Kill the word behind point. Word boundaries are the same as
+ those used by &#x1b;1mbackward-word&#x1b;22m.
+ &#x1b;1munix-word-rubout (C-w)&#x1b;0m
+ Kill the word behind point, using white space as a word bound-
+ ary. The killed text is saved on the kill-ring.
+ &#x1b;1munix-filename-rubout&#x1b;0m
+ Kill the word behind point, using white space and the slash
+ character as the word boundaries. The killed text is saved on
+ the kill-ring.
+ &#x1b;1mdelete-horizontal-space (M-\)&#x1b;0m
+ Delete all spaces and tabs around point.
+ &#x1b;1mkill-region&#x1b;0m
+ Kill the text between the point and &#x1b;4mmark&#x1b;24m (saved cursor posi-
+ tion). This text is referred to as the &#x1b;4mregion&#x1b;24m.
+ &#x1b;1mcopy-region-as-kill&#x1b;0m
+ Copy the text in the region to the kill buffer.
+ &#x1b;1mcopy-backward-word&#x1b;0m
+ Copy the word before point to the kill buffer. The word bound-
+ aries are the same as &#x1b;1mbackward-word&#x1b;22m.
+ &#x1b;1mcopy-forward-word&#x1b;0m
+ Copy the word following point to the kill buffer. The word
+ boundaries are the same as &#x1b;1mforward-word&#x1b;22m.
+ &#x1b;1myank (C-y)&#x1b;0m
+ Yank the top of the kill ring into the buffer at point.
+ &#x1b;1myank-pop (M-y)&#x1b;0m
+ Rotate the kill ring, and yank the new top. Only works follow-
+ ing &#x1b;1myank &#x1b;22mor &#x1b;1myank-pop&#x1b;22m.
+
+ &#x1b;1mNumeric Arguments&#x1b;0m
+ &#x1b;1mdigit-argument (M-0, M-1, ..., M--)&#x1b;0m
+ Add this digit to the argument already accumulating, or start a
+ new argument. M-- starts a negative argument.
+ &#x1b;1muniversal-argument&#x1b;0m
+ This is another way to specify an argument. If this command is
+ followed by one or more digits, optionally with a leading minus
+ sign, those digits define the argument. If the command is fol-
+ lowed by digits, executing &#x1b;1muniversal-argument &#x1b;22magain ends the nu-
+ meric argument, but is otherwise ignored. As a special case, if
+ this command is immediately followed by a character that is nei-
+ ther a digit or minus sign, the argument count for the next com-
+ mand is multiplied by four. The argument count is initially
+ one, so executing this function the first time makes the argu-
+ ment count four, a second time makes the argument count sixteen,
+ and so on.
+
+ &#x1b;1mCompleting&#x1b;0m
+ &#x1b;1mcomplete (TAB)&#x1b;0m
+ Attempt to perform completion on the text before point. The ac-
+ tual completion performed is application-specific. &#x1b;1mBash&#x1b;22m, for
+ instance, attempts completion treating the text as a variable
+ (if the text begins with &#x1b;1m$&#x1b;22m), username (if the text begins with
+ &#x1b;1m~&#x1b;22m), hostname (if the text begins with &#x1b;1m@&#x1b;22m), or command (including
+ aliases and functions) in turn. If none of these produces a
+ match, filename completion is attempted. &#x1b;1mGdb&#x1b;22m, on the other
+ hand, allows completion of program functions and variables, and
+ only attempts filename completion under certain circumstances.
+ &#x1b;1mpossible-completions (M-?)&#x1b;0m
+ List the possible completions of the text before point. When
+ displaying completions, readline sets the number of columns used
+ for display to the value of &#x1b;1mcompletion-display-width&#x1b;22m, the value
+ of the environment variable &#x1b;1mCOLUMNS&#x1b;22m, or the screen width, in
+ that order.
+ &#x1b;1minsert-completions (M-*)&#x1b;0m
+ Insert all completions of the text before point that would have
+ been generated by &#x1b;1mpossible-completions&#x1b;22m.
+ &#x1b;1mmenu-complete&#x1b;0m
+ Similar to &#x1b;1mcomplete&#x1b;22m, but replaces the word to be completed with
+ a single match from the list of possible completions. Repeated
+ execution of &#x1b;1mmenu-complete &#x1b;22msteps through the list of possible
+ completions, inserting each match in turn. At the end of the
+ list of completions, the bell is rung (subject to the setting of
+ &#x1b;1mbell-style&#x1b;22m) and the original text is restored. An argument of &#x1b;4mn&#x1b;0m
+ moves &#x1b;4mn&#x1b;24m positions forward in the list of matches; a negative ar-
+ gument may be used to move backward through the list. This com-
+ mand is intended to be bound to &#x1b;1mTAB&#x1b;22m, but is unbound by default.
+ &#x1b;1mmenu-complete-backward&#x1b;0m
+ Identical to &#x1b;1mmenu-complete&#x1b;22m, but moves backward through the list
+ of possible completions, as if &#x1b;1mmenu-complete &#x1b;22mhad been given a
+ negative argument. This command is unbound by default.
+ &#x1b;1mdelete-char-or-list&#x1b;0m
+ Deletes the character under the cursor if not at the beginning
+ or end of the line (like &#x1b;1mdelete-char&#x1b;22m). If at the end of the
+ line, behaves identically to &#x1b;1mpossible-completions&#x1b;22m.
+
+ &#x1b;1mKeyboard Macros&#x1b;0m
+ &#x1b;1mstart-kbd-macro (C-x ()&#x1b;0m
+ Begin saving the characters typed into the current keyboard
+ macro.
+ &#x1b;1mend-kbd-macro (C-x ))&#x1b;0m
+ Stop saving the characters typed into the current keyboard macro
+ and store the definition.
+ &#x1b;1mcall-last-kbd-macro (C-x e)&#x1b;0m
+ Re-execute the last keyboard macro defined, by making the char-
+ acters in the macro appear as if typed at the keyboard.
+ &#x1b;1mprint-last-kbd-macro ()&#x1b;0m
+ Print the last keyboard macro defined in a format suitable for
+ the &#x1b;4minputrc&#x1b;24m file.
+
+ &#x1b;1mMiscellaneous&#x1b;0m
+ &#x1b;1mre-read-init-file (C-x C-r)&#x1b;0m
+ Read in the contents of the &#x1b;4minputrc&#x1b;24m file, and incorporate any
+ bindings or variable assignments found there.
+ &#x1b;1mabort (C-g)&#x1b;0m
+ Abort the current editing command and ring the terminal's bell
+ (subject to the setting of &#x1b;1mbell-style&#x1b;22m).
+ &#x1b;1mdo-lowercase-version (M-A, M-B, M-&#x1b;4m&#x1b;22mx&#x1b;24m&#x1b;1m, ...)&#x1b;0m
+ If the metafied character &#x1b;4mx&#x1b;24m is uppercase, run the command that
+ is bound to the corresponding metafied lowercase character. The
+ behavior is undefined if &#x1b;4mx&#x1b;24m is already lowercase.
+ &#x1b;1mprefix-meta (ESC)&#x1b;0m
+ Metafy the next character typed. &#x1b;1mESC f &#x1b;22mis equivalent to &#x1b;1mMeta-f&#x1b;22m.
+ &#x1b;1mundo (C-_, C-x C-u)&#x1b;0m
+ Incremental undo, separately remembered for each line.
+ &#x1b;1mrevert-line (M-r)&#x1b;0m
+ Undo all changes made to this line. This is like executing the
+ &#x1b;1mundo &#x1b;22mcommand enough times to return the line to its initial
+ state.
+ &#x1b;1mtilde-expand (M-&)&#x1b;0m
+ Perform tilde expansion on the current word.
+ &#x1b;1mset-mark (C-@, M-<space>)&#x1b;0m
+ Set the mark to the point. If a numeric argument is supplied,
+ the mark is set to that position.
+ &#x1b;1mexchange-point-and-mark (C-x C-x)&#x1b;0m
+ Swap the point with the mark. The current cursor position is
+ set to the saved position, and the old cursor position is saved
+ as the mark.
+ &#x1b;1mcharacter-search (C-)&#x1b;0m
+ A character is read and point is moved to the next occurrence of
+ that character. A negative count searches for previous occur-
+ rences.
+ &#x1b;1mcharacter-search-backward (M-C-)&#x1b;0m
+ A character is read and point is moved to the previous occur-
+ rence of that character. A negative count searches for subse-
+ quent occurrences.
+ &#x1b;1mskip-csi-sequence&#x1b;0m
+ Read enough characters to consume a multi-key sequence such as
+ those defined for keys like Home and End. Such sequences begin
+ with a Control Sequence Indicator (CSI), usually ESC-. If this
+ sequence is bound to "\", keys producing such sequences will
+ have no effect unless explicitly bound to a readline command,
+ instead of inserting stray characters into the editing buffer.
+ This is unbound by default, but usually bound to ESC-.
+ &#x1b;1minsert-comment (M-#)&#x1b;0m
+ Without a numeric argument, the value of the readline &#x1b;1mcom-&#x1b;0m
+ &#x1b;1mment-begin &#x1b;22mvariable is inserted at the beginning of the current
+ line. If a numeric argument is supplied, this command acts as a
+ toggle: if the characters at the beginning of the line do not
+ match the value of &#x1b;1mcomment-begin&#x1b;22m, the value is inserted, other-
+ wise the characters in &#x1b;1mcomment-begin &#x1b;22mare deleted from the begin-
+ ning of the line. In either case, the line is accepted as if a
+ newline had been typed. The default value of &#x1b;1mcomment-begin&#x1b;0m
+ makes the current line a shell comment. If a numeric argument
+ causes the comment character to be removed, the line will be ex-
+ ecuted by the shell.
+ &#x1b;1mdump-functions&#x1b;0m
+ Print all of the functions and their key bindings to the read-
+ line output stream. If a numeric argument is supplied, the out-
+ put is formatted in such a way that it can be made part of an
+ &#x1b;4minputrc&#x1b;24m file.
+ &#x1b;1mdump-variables&#x1b;0m
+ Print all of the settable variables and their values to the
+ readline output stream. If a numeric argument is supplied, the
+ output is formatted in such a way that it can be made part of an
+ &#x1b;4minputrc&#x1b;24m file.
+ &#x1b;1mdump-macros&#x1b;0m
+ Print all of the readline key sequences bound to macros and the
+ strings they output. If a numeric argument is supplied, the
+ output is formatted in such a way that it can be made part of an
+ &#x1b;4minputrc&#x1b;24m file.
+ &#x1b;1memacs-editing-mode (C-e)&#x1b;0m
+ When in &#x1b;1mvi &#x1b;22mcommand mode, this causes a switch to &#x1b;1memacs &#x1b;22mediting
+ mode.
+ &#x1b;1mvi-editing-mode (M-C-j)&#x1b;0m
+ When in &#x1b;1memacs &#x1b;22mediting mode, this causes a switch to &#x1b;1mvi &#x1b;22mediting
+ mode.
+
+&#x1b;1mDEFAULT KEY BINDINGS&#x1b;0m
+ The following is a list of the default emacs and vi bindings. Charac-
+ ters with the eighth bit set are written as M-<character>, and are re-
+ ferred to as &#x1b;4mmetafied&#x1b;24m characters. The printable ASCII characters not
+ mentioned in the list of emacs standard bindings are bound to the
+ &#x1b;1mself-insert &#x1b;22mfunction, which just inserts the given character into the
+ input line. In vi insertion mode, all characters not specifically men-
+ tioned are bound to &#x1b;1mself-insert&#x1b;22m. Characters assigned to signal genera-
+ tion by &#x1b;4mstty&#x1b;24m(1) or the terminal driver, such as C-Z or C-C, retain that
+ function. Upper and lower case metafied characters are bound to the
+ same function in the emacs mode meta keymap. The remaining characters
+ are unbound, which causes readline to ring the bell (subject to the
+ setting of the &#x1b;1mbell-style &#x1b;22mvariable).

+.if t Readline is Copyright \(co 1989\-2020 Free Software Foundation, Inc.
+.SH DESCRIPTION
+.LP
+.B readline
+will read a line from the terminal
+and return it, using
+.B prompt
+as a prompt. If 
+.B prompt
+is \fBNULL\fP or the empty string, no prompt is issued.
+The line returned is allocated with
+.IR malloc (3);
+the caller must free it when finished. The line returned
+has the final newline removed, so only the text of the line
+remains.
+.LP
+.B readline
+offers editing capabilities while the user is entering the
+line.
+By default, the line editing commands
+are similar to those of emacs.
+A vi\-style line editing interface is also available.
+.LP
+This manual page describes only the most basic use of \fBreadline\fP.
+Much more functionality is available; see
+\fIThe GNU Readline Library\fP and \fIThe GNU History Library\fP
+for additional information.
+.SH RETURN VALUE
+.LP
+.B readline
+returns the text of the line read. A blank line
+returns the empty string. If
+.B EOF
+is encountered while reading a line, and the line is empty,
+.B NULL
+is returned. If an
+.B EOF
+is read with a non\-empty line, it is
+treated as a newline.
+.SH NOTATION
+.LP
+An Emacs-style notation is used to denote
+keystrokes. Control keys are denoted by C\-\fIkey\fR, e.g., C\-n
+means Control\-N. Similarly,
+.I meta
+keys are denoted by M\-\fIkey\fR, so M\-x means Meta\-X. (On keyboards
+without a
+.I meta
+key, M\-\fIx\fP means ESC \fIx\fP, i.e., press the Escape key
+then the
+.I x
+key. This makes ESC the \fImeta prefix\fP.
+The combination M\-C\-\fIx\fP means ESC\-Control\-\fIx\fP,
+or press the Escape key
+then hold the Control key while pressing the
+.I x
+key.)
+.PP
+Readline commands may be given numeric
+.IR arguments ,
+which normally act as a repeat count. Sometimes, however, it is the
+sign of the argument that is significant. Passing a negative argument
+to a command that acts in the forward direction (e.g., \fBkill\-line\fP)
+causes that command to act in a backward direction.
+Commands whose behavior with arguments deviates from this are noted
+below.
+.PP
+When a command is described as \fIkilling\fP text, the text
+deleted is saved for possible future retrieval
+(\fIyanking\fP). The killed text is saved in a
+\fIkill ring\fP. Consecutive kills cause the text to be
+accumulated into one unit, which can be yanked all at once.
+Commands which do not kill text separate the chunks of text
+on the kill ring.
+.SH INITIALIZATION FILE
+.LP
+Readline is customized by putting commands in an initialization
+file (the \fIinputrc\fP file).
+The name of this file is taken from the value of the
+.B INPUTRC
+environment variable. If that variable is unset, the default is
+.IR ~/.inputrc .
+If that file does not exist or cannot be read, the ultimate default is
+.IR /etc/inputrc .
+When a program which uses the readline library starts up, the
+init file is read, and the key bindings and variables are set.
+There are only a few basic constructs allowed in the
+readline init file. Blank lines are ignored.
+Lines beginning with a \fB#\fP are comments.
+Lines beginning with a \fB$\fP indicate conditional constructs.
+Other lines denote key bindings and variable settings.
+Each program using this library may add its own commands
+and bindings.
+.PP
+For example, placing
+.RS
+.PP
+M\-Control\-u: universal\-argument
+.RE
+or
+.RS
+C\-Meta\-u: universal\-argument
+.RE
+.sp
+into the
+.I inputrc
+would make M\-C\-u execute the readline command
+.IR universal\-argument .
+.PP
+The following symbolic character names are recognized while
+processing key bindings:
+.IR DEL ,
+.IR ESC ,
+.IR ESCAPE ,
+.IR LFD ,
+.IR NEWLINE ,
+.IR RET ,
+.IR RETURN ,
+.IR RUBOUT ,
+.IR SPACE ,
+.IR SPC ,
+and
+.IR TAB .
+.PP
+In addition to command names, readline allows keys to be bound
+to a string that is inserted when the key is pressed (a \fImacro\fP).
+.PP
+.SS Key Bindings
+The syntax for controlling key bindings in the
+.I inputrc
+file is simple. All that is required is the name of the
+command or the text of a macro and a key sequence to which
+it should be bound. The name may be specified in one of two ways:
+as a symbolic key name, possibly with \fIMeta\-\fP or \fIControl\-\fP
+prefixes, or as a key sequence.
+The name and key sequence are separated by a colon. There can be no
+whitespace between the name and the colon.
+.PP
+When using the form \fBkeyname\fP:\^\fIfunction-name\fP or \fImacro\fP,
+.I keyname
+is the name of a key spelled out in English. For example:
+.sp
+.RS
+Control\-u: universal\-argument
+.br
+Meta\-Rubout: backward\-kill\-word
+.br
+Control\-o: "> output"
+.RE
+.LP
+In the above example,
+.I C\-u
+is bound to the function
+.BR universal\-argument ,
+.I M-DEL
+is bound to the function
+.BR backward\-kill\-word ,
+and
+.I C\-o
+is bound to run the macro
+expressed on the right hand side (that is, to insert the text
+.if t \f(CW> output\fP
+.if n ``> output''
+into the line).
+.PP
+In the second form, \fB"keyseq"\fP:\^\fIfunction\-name\fP or \fImacro\fP,
+.B keyseq
+differs from
+.B keyname
+above in that strings denoting
+an entire key sequence may be specified by placing the sequence
+within double quotes. Some GNU Emacs style key escapes can be
+used, as in the following example, but the symbolic character names
+are not recognized.
+.sp
+.RS
+"\eC\-u": universal\-argument
+.br
+"\eC\-x\eC\-r": re\-read\-init\-file
+.br
+"\ee11~": "Function Key 1"
+.RE
+.PP
+In this example,
+.I C-u
+is again bound to the function
+.BR universal\-argument .
+.I "C-x C-r"
+is bound to the function
+.BR re\-read\-init\-file ,
+and
+.I "ESC 1 1 ~"
+is bound to insert the text
+.if t \f(CWFunction Key 1\fP.
+.if n ``Function Key 1''.
+.PP
+The full set of GNU Emacs style escape sequences available when specifying
+key sequences is
+.RS
+.PD 0
+.TP
+.B \eC\-
+control prefix
+.TP
+.B \eM\-
+meta prefix
+.TP
+.B \ee
+an escape character
+.TP
+.B \e\e
+backslash
+.TP
+.B \e"
+literal ", a double quote
+.TP
+.B \e'
+literal ', a single quote
+.RE
+.PD
+.PP
+In addition to the GNU Emacs style escape sequences, a second
+set of backslash escapes is available:
+.RS
+.PD 0
+.TP
+.B \ea
+alert (bell)
+.TP
+.B \eb
+backspace
+.TP
+.B \ed
+delete
+.TP
+.B \ef
+form feed
+.TP
+.B \en
+newline
+.TP
+.B \er
+carriage return
+.TP
+.B \et
+horizontal tab
+.TP
+.B \ev
+vertical tab
+.TP
+.B \e\fInnn\fP
+the eight-bit character whose value is the octal value \fInnn\fP
+(one to three digits)
+.TP
+.B \ex\fIHH\fP
+the eight-bit character whose value is the hexadecimal value \fIHH\fP
+(one or two hex digits)
+.RE
+.PD
+.PP
+When entering the text of a macro, single or double quotes should
+be used to indicate a macro definition. Unquoted text
+is assumed to be a function name.
+In the macro body, the backslash escapes described above are expanded.
+Backslash will quote any other character in the macro text,
+including " and '.
+.PP
+.B Bash
+allows the current readline key bindings to be displayed or modified
+with the
+.B bind
+builtin command. The editing mode may be switched during interactive
+use by using the
+.B \-o
+option to the
+.B set
+builtin command. Other programs using this library provide
+similar mechanisms. The
+.I inputrc
+file may be edited and re-read if a program does not provide
+any other means to incorporate new bindings.
+.SS Variables
+Readline has variables that can be used to further customize its
+behavior. A variable may be set in the
+.I inputrc
+file with a statement of the form
+.RS
+.PP
+\fBset\fP \fIvariable\-name\fP \fIvalue\fP
+.RE
+.PP
+Except where noted, readline variables can take the values
+.B On
+or
+.B Off
+(without regard to case).
+Unrecognized variable names are ignored.
+When a variable value is read, empty or null values, "on" (case-insensitive),
+and "1" are equivalent to \fBOn\fP. All other values are equivalent to
+\fBOff\fP.
+The variables and their default values are:
+.PP
+.PD 0
+.TP
+.B bell\-style (audible)
+Controls what happens when readline wants to ring the terminal bell.
+If set to \fBnone\fP, readline never rings the bell. If set to
+\fBvisible\fP, readline uses a visible bell if one is available.
+If set to \fBaudible\fP, readline attempts to ring the terminal's bell.
+.TP
+.B bind\-tty\-special\-chars (On)
+If set to \fBOn\fP (the default), readline attempts to bind the control
+characters treated specially by the kernel's terminal driver to their
+readline equivalents.
+.TP
+.B blink\-matching\-paren (Off)
+If set to \fBOn\fP, readline attempts to briefly move the cursor to an
+opening parenthesis when a closing parenthesis is inserted.
+.TP
+.B colored\-completion\-prefix (Off)
+If set to \fBOn\fP, when listing completions, readline displays the
+common prefix of the set of possible completions using a different color.
+The color definitions are taken from the value of the \fBLS_COLORS\fP
+environment variable.
+.TP
+.B colored\-stats (Off)
+If set to \fBOn\fP, readline displays possible completions using different
+colors to indicate their file type.
+The color definitions are taken from the value of the \fBLS_COLORS\fP
+environment variable.
+.TP
+.B comment\-begin (``#'')
+The string that is inserted in \fBvi\fP mode when the
+.B insert\-comment
+command is executed.
+This command is bound to
+.B M\-#
+in emacs mode and to
+.B #
+in vi command mode.
+.TP
+.B completion\-display\-width (\-1)
+The number of screen columns used to display possible matches
+when performing completion.
+The value is ignored if it is less than 0 or greater than the terminal
+screen width.
+A value of 0 will cause matches to be displayed one per line.
+The default value is \-1.
+.TP 
+.B completion\-ignore\-case (Off)
+If set to \fBOn\fP, readline performs filename matching and completion
+in a case\-insensitive fashion.
+.TP
+.B completion\-map\-case (Off)
+If set to \fBOn\fP, and \fBcompletion\-ignore\-case\fP is enabled, readline
+treats hyphens (\fI\-\fP) and underscores (\fI_\fP) as equivalent when
+performing case\-insensitive filename matching and completion.
+.TP
+.B completion\-prefix\-display\-length (0)
+The length in characters of the common prefix of a list of possible
+completions that is displayed without modification. When set to a
+value greater than zero, common prefixes longer than this value are
+replaced with an ellipsis when displaying possible completions.
+.TP
+.B completion\-query\-items (100)
+This determines when the user is queried about viewing
+the number of possible completions
+generated by the \fBpossible\-completions\fP command.
+It may be set to any integer value greater than or equal to zero.
+If the number of possible completions is greater than
+or equal to the value of this variable,
+readline will ask whether or not the user wishes to view them;
+otherwise they are simply listed
+on the terminal. A negative value causes readline to never ask.
+.TP
+.B convert\-meta (On)
+If set to \fBOn\fP, readline will convert characters with the
+eighth bit set to an ASCII key sequence
+by stripping the eighth bit and prefixing it with an
+escape character (in effect, using escape as the \fImeta prefix\fP).
+The default is \fIOn\fP, but readline will set it to \fIOff\fP if the
+locale contains eight-bit characters.
+.TP
+.B disable\-completion (Off)
+If set to \fBOn\fP, readline will inhibit word completion. Completion 
+characters will be inserted into the line as if they had been
+mapped to \fBself-insert\fP.
+.TP
+.B echo\-control\-characters (On)
+When set to \fBOn\fP, on operating systems that indicate they support it,
+readline echoes a character corresponding to a signal generated from the
+keyboard.
+.TP
+.B editing\-mode (emacs)
+Controls whether readline begins with a set of key bindings similar
+to \fIEmacs\fP or \fIvi\fP.
+.B editing\-mode
+can be set to either
+.B emacs
+or
+.BR vi .
+.TP
+.B emacs\-mode\-string (@)
+If the \fIshow\-mode\-in\-prompt\fP variable is enabled, 
+this string is displayed immediately before the last line of the primary
+prompt when emacs editing mode is active. The value is expanded like a
+key binding, so the standard set of meta- and control prefixes and
+backslash escape sequences is available.
+Use the \e1 and \e2 escapes to begin and end sequences of
+non-printing characters, which can be used to embed a terminal control 
+sequence into the mode string.
+.TP
+.B enable\-bracketed\-paste (On)
+When set to \fBOn\fP, readline will configure the terminal in a way
+that will enable it to insert each paste into the editing buffer as a
+single string of characters, instead of treating each character as if
+it had been read from the keyboard. This can prevent pasted characters
+from being interpreted as editing commands.
+.TP
+.B enable\-keypad (Off)
+When set to \fBOn\fP, readline will try to enable the application
+keypad when it is called. Some systems need this to enable the
+arrow keys.
+.TP
+.B enable\-meta\-key (On)
+When set to \fBOn\fP, readline will try to enable any meta modifier
+key the terminal claims to support when it is called. On many terminals,
+the meta key is used to send eight-bit characters.
+.TP
+.B expand\-tilde (Off)
+If set to \fBOn\fP, tilde expansion is performed when readline
+attempts word completion.
+.TP
+.B history\-preserve\-point (Off)
+If set to \fBOn\fP, the history code attempts to place point at the 
+same location on each history line retrieved with \fBprevious-history\fP 
+or \fBnext-history\fP.
+.TP
+.B history\-size (unset)
+Set the maximum number of history entries saved in the history list.
+If set to zero, any existing history entries are deleted and no new entries
+are saved.
+If set to a value less than zero, the number of history entries is not
+limited.
+By default, the number of history entries is not limited.
+If an attempt is made to set \fIhistory\-size\fP to a non-numeric value,
+the maximum number of history entries will be set to 500.
+.TP
+.B horizontal\-scroll\-mode (Off)
+When set to \fBOn\fP, makes readline use a single line for display,
+scrolling the input horizontally on a single screen line when it
+becomes longer than the screen width rather than wrapping to a new line.
+This setting is automatically enabled for terminals of height 1.
+.TP
+.B input\-meta (Off)
+If set to \fBOn\fP, readline will enable eight-bit input (that is,
+it will not clear the eighth bit in the characters it reads),
+regardless of what the terminal claims it can support. The name
+.B meta\-flag
+is a synonym for this variable.
+The default is \fIOff\fP, but readline will set it to \fIOn\fP if the 
+locale contains eight-bit characters.
+.TP
+.B isearch\-terminators (``C\- C\-J'')
+The string of characters that should terminate an incremental
+search without subsequently executing the character as a command.
+If this variable has not been given a value, the characters
+\fIESC\fP and \fIC\-J\fP will terminate an incremental search.
+.TP
+.B keymap (emacs)
+Set the current readline keymap. The set of legal keymap names is
+\fIemacs, emacs-standard, emacs-meta, emacs-ctlx, vi, vi-move,
+vi-command\fP, and
+.IR vi-insert .
+\fIvi\fP is equivalent to \fIvi-command\fP; \fIemacs\fP is
+equivalent to \fIemacs-standard\fP. The default value is
+.IR emacs .
+The value of
+.B editing\-mode
+also affects the default keymap.
+.TP
+.B keyseq\-timeout (500)
+Specifies the duration \fIreadline\fP will wait for a character when reading an
+ambiguous key sequence (one that can form a complete key sequence using
+the input read so far, or can take additional input to complete a longer 
+key sequence).
+If no input is received within the timeout, \fIreadline\fP will use the shorter
+but complete key sequence.
+The value is specified in milliseconds, so a value of 1000 means that
+\fIreadline\fP will wait one second for additional input.
+If this variable is set to a value less than or equal to zero, or to a
+non-numeric value, \fIreadline\fP will wait until another key is pressed to
+decide which key sequence to complete.
+.TP
+.B mark\-directories (On)
+If set to \fBOn\fP, completed directory names have a slash
+appended.
+.TP
+.B mark\-modified\-lines (Off)
+If set to \fBOn\fP, history lines that have been modified are displayed
+with a preceding asterisk (\fB*\fP).
+.TP
+.B mark\-symlinked\-directories (Off)
+If set to \fBOn\fP, completed names which are symbolic links to directories
+have a slash appended (subject to the value of
+\fBmark\-directories\fP).
+.TP
+.B match\-hidden\-files (On)
+This variable, when set to \fBOn\fP, causes readline to match files whose 
+names begin with a `.' (hidden files) when performing filename
+completion.
+If set to \fBOff\fP, the leading `.' must be
+supplied by the user in the filename to be completed.
+.TP
+.B menu\-complete\-display\-prefix (Off)
+If set to \fBOn\fP, menu completion displays the common prefix of the
+list of possible completions (which may be empty) before cycling through
+the list.
+.TP
+.B output\-meta (Off)
+If set to \fBOn\fP, readline will display characters with the
+eighth bit set directly rather than as a meta-prefixed escape
+sequence.
+The default is \fIOff\fP, but readline will set it to \fIOn\fP if the
+locale contains eight-bit characters.
+.TP
+.B page\-completions (On)
+If set to \fBOn\fP, readline uses an internal \fImore\fP-like pager
+to display a screenful of possible completions at a time.
+.TP
+.B print\-completions\-horizontally (Off)
+If set to \fBOn\fP, readline will display completions with matches
+sorted horizontally in alphabetical order, rather than down the screen.
+.TP
+.B revert\-all\-at\-newline (Off)
+If set to \fBOn\fP, readline will undo all changes to history lines
+before returning when \fBaccept\-line\fP is executed. By default,
+history lines may be modified and retain individual undo lists across
+calls to \fBreadline\fP.
+.TP
+.B show\-all\-if\-ambiguous (Off)
+This alters the default behavior of the completion functions. If
+set to
+.BR On ,
+words which have more than one possible completion cause the
+matches to be listed immediately instead of ringing the bell.
+.TP
+.B show\-all\-if\-unmodified (Off)
+This alters the default behavior of the completion functions in
+a fashion similar to \fBshow\-all\-if\-ambiguous\fP.
+If set to
+.BR On , 
+words which have more than one possible completion without any
+possible partial completion (the possible completions don't share 
+a common prefix) cause the matches to be listed immediately instead
+of ringing the bell.
+.TP
+.B show\-mode\-in\-prompt (Off)
+If set to \fBOn\fP, add a string to the beginning of the prompt
+indicating the editing mode: emacs, vi command, or vi insertion.
+The mode strings are user-settable (e.g., \fIemacs\-mode\-string\fP).
+.TP
+.B skip\-completed\-text (Off)
+If set to \fBOn\fP, this alters the default completion behavior when
+inserting a single match into the line. It's only active when
+performing completion in the middle of a word. If enabled, readline
+does not insert characters from the completion that match characters
+after point in the word being completed, so portions of the word
+following the cursor are not duplicated.
+.TP
+.B vi\-cmd\-mode\-string ((cmd))
+If the \fIshow\-mode\-in\-prompt\fP variable is enabled, 
+this string is displayed immediately before the last line of the primary
+prompt when vi editing mode is active and in command mode.
+The value is expanded like a
+key binding, so the standard set of meta- and control prefixes and
+backslash escape sequences is available.
+Use the \e1 and \e2 escapes to begin and end sequences of
+non-printing characters, which can be used to embed a terminal control
+sequence into the mode string.
+.TP
+.B vi\-ins\-mode\-string ((ins))
+If the \fIshow\-mode\-in\-prompt\fP variable is enabled, 
+this string is displayed immediately before the last line of the primary
+prompt when vi editing mode is active and in insertion mode. 
+The value is expanded like a
+key binding, so the standard set of meta- and control prefixes and 
+backslash escape sequences is available.
+Use the \e1 and \e2 escapes to begin and end sequences of
+non-printing characters, which can be used to embed a terminal control 
+sequence into the mode string.
+.TP
+.B visible\-stats (Off)
+If set to \fBOn\fP, a character denoting a file's type as reported 
+by \fIstat\fP(2) is appended to the filename when listing possible
+completions.
+.PD
+.SS Conditional Constructs
+Readline implements a facility similar in spirit to the conditional
+compilation features of the C preprocessor which allows key
+bindings and variable settings to be performed as the result
+of tests. There are four parser directives used.
+.IP \fB$if\fP
+The
+.B $if
+construct allows bindings to be made based on the
+editing mode, the terminal being used, or the application using
+readline. The text of the test, after any comparison operator,
+extends to the end of the line;
+unless otherwise noted, no characters are required to isolate it.
+.RS
+.IP \fBmode\fP
+The \fBmode=\fP form of the \fB$if\fP directive is used to test
+whether readline is in emacs or vi mode.
+This may be used in conjunction
+with the \fBset keymap\fP command, for instance, to set bindings in
+the \fIemacs-standard\fP and \fIemacs-ctlx\fP keymaps only if
+readline is starting out in emacs mode.
+.IP \fBterm\fP
+The \fBterm=\fP form may be used to include terminal-specific
+key bindings, perhaps to bind the key sequences output by the
+terminal's function keys. The word on the right side of the
+.B =
+is tested against the full name of the terminal and the portion
+of the terminal name before the first \fB\-\fP. This allows
+.I sun
+to match both
+.I sun
+and
+.IR sun\-cmd ,
+for instance.
+.IP \fBversion\fP
+The \fBversion\fP test may be used to perform comparisons against
+specific readline versions.
+The \fBversion\fP expands to the current readline version.
+The set of comparison operators includes
+.BR = ,
+(and
+.BR == ),
+.BR != ,
+.BR <= ,
+.BR >= ,
+.BR < ,
+and
+.BR > .
+The version number supplied on the right side of the operator consists
+of a major version number, an optional decimal point, and an optional
+minor version (e.g., \fB7.1\fP). If the minor version is omitted, it
+is assumed to be \fB0\fP.
+The operator may be separated from the string \fBversion\fP
+and from the version number argument by whitespace.
+.IP \fBapplication\fP
+The \fBapplication\fP construct is used to include
+application-specific settings. Each program using the readline
+library sets the \fIapplication name\fP, and an initialization
+file can test for a particular value.
+This could be used to bind key sequences to functions useful for
+a specific program. For instance, the following command adds a
+key sequence that quotes the current or previous word in \fBbash\fP:
+.sp 1
+.RS
+.nf
+\fB$if\fP Bash
+# Quote the current or previous word
+"\eC-xq": "\eeb\e"\eef\e""
+\fB$endif\fP
+.fi
+.RE
+.IP \fIvariable\fP
+The \fIvariable\fP construct provides simple equality tests for readline
+variables and values.
+The permitted comparison operators are \fI=\fP, \fI==\fP, and \fI!=\fP.
+The variable name must be separated from the comparison operator by
+whitespace; the operator may be separated from the value on the right hand
+side by whitespace.
+Both string and boolean variables may be tested. Boolean variables must be
+tested against the values \fIon\fP and \fIoff\fP.
+.RE
+.IP \fB$endif\fP
+This command, as seen in the previous example, terminates an
+\fB$if\fP command.
+.IP \fB$else\fP
+Commands in this branch of the \fB$if\fP directive are executed if
+the test fails.
+.IP \fB$include\fP
+This directive takes a single filename as an argument and reads commands
+and bindings from that file. For example, the following directive
+would read \fI/etc/inputrc\fP:
+.sp 1
+.RS
+.nf
+\fB$include\fP \^ \fI/etc/inputrc\fP
+.fi 
+.RE
+.SH SEARCHING
+Readline provides commands for searching through the command history
+for lines containing a specified string.
+There are two search modes:
+.I incremental
+and
+.IR non-incremental .
+.PP
+Incremental searches begin before the user has finished typing the
+search string.
+As each character of the search string is typed, readline displays
+the next entry from the history matching the string typed so far.
+An incremental search requires only as many characters as needed to
+find the desired history entry.
+To search backward in the history for a particular string, type
+\fBC\-r\fP. Typing \fBC\-s\fP searches forward through the history.
+The characters present in the value of the \fBisearch-terminators\fP
+variable are used to terminate an incremental search.
+If that variable has not been assigned a value the \fIEscape\fP and
+\fBC\-J\fP characters will terminate an incremental search.
+\fBC\-G\fP will abort an incremental search and restore the original
+line.
+When the search is terminated, the history entry containing the
+search string becomes the current line.
+.PP
+To find other matching entries in the history list, type \fBC\-s\fP or
+\fBC\-r\fP as appropriate.
+This will search backward or forward in the history for the next
+line matching the search string typed so far.
+Any other key sequence bound to a readline command will terminate
+the search and execute that command.
+For instance, a newline will terminate the search and accept
+the line, thereby executing the command from the history list.
+A movement command will terminate the search, make the last line found
+the current line, and begin editing.
+.PP
+Non-incremental searches read the entire search string before starting
+to search for matching history lines. The search string may be
+typed by the user or be part of the contents of the current line.
+.SH EDITING COMMANDS
+The following is a list of the names of the commands and the default
+key sequences to which they are bound.
+Command names without an accompanying key sequence are unbound by default.
+.PP
+In the following descriptions, \fIpoint\fP refers to the current cursor
+position, and \fImark\fP refers to a cursor position saved by the
+\fBset\-mark\fP command.
+The text between the point and mark is referred to as the \fIregion\fP.

+the second word on the previous line) at point.
+With an argument
+.IR n ,
+insert the \fIn\fPth word from the previous command (the words
+in the previous command begin with word 0). A negative argument
+inserts the \fIn\fPth word from the end of the previous command.

+With a numeric argument, behave exactly like \fByank\-nth\-arg\fP.
+Successive calls to \fByank\-last\-arg\fP move back through the history
+list, inserting the last word (or the word specified by the argument to
+the first call) of each line in turn.
+Any numeric argument supplied to these successive calls determines
+the direction to move through the history. A negative argument switches
+the direction through the history (back or forward).
+The history expansion facilities are used to extract the last argument,
+as if the "!$" history expansion had been specified.

+.if n ``stty''.
+If this character is read when there are no characters
+on the line, and point is at the beginning of the line, Readline
+interprets it as the end of input and returns
+.SM
+.BR EOF .
+.TP
+.B delete\-char (C\-d)

+.TP
+.B backward\-delete\-char (Rubout)
+Delete the character behind the cursor. When given a numeric argument,
+save the deleted text on the kill ring.
+.TP
+.B forward\-backward\-delete\-char 
+Delete the character under the cursor, unless the cursor is at the
+end of the line, in which case the character behind the cursor is
+deleted.
+.TP
+.B quoted\-insert (C\-q, C\-v)
+Add the next character that you type to the line verbatim. This is

+Insert the character typed.
+.TP
+.B transpose\-chars (C\-t)
+Drag the character before point forward over the character at point,

+.TP
+.B upcase\-word (M\-u)
+Uppercase the current (or following) word. With a negative argument,
+uppercase the previous word, but do not move point.
+.TP
+.B downcase\-word (M\-l)
+Lowercase the current (or following) word. With a negative argument,
+lowercase the previous word, but do not move point.
+.TP
+.B capitalize\-word (M\-c)
+Capitalize the current (or following) word. With a negative argument,
+capitalize the previous word, but do not move point.
+.TP
+.B overwrite\-mode
+Toggle overwrite mode. With an explicit positive numeric argument,
+switches to overwrite mode. With an explicit non-positive numeric
+argument, switches to insert mode. This command affects only
+\fBemacs\fP mode; \fBvi\fP mode does overwrite differently.
+Each call to \fIreadline()\fP starts in insert mode.
+In overwrite mode, characters bound to \fBself\-insert\fP replace

+.B universal\-argument
+This is another way to specify an argument.
+If this command is followed by one or more digits, optionally with a

+.PD 0
+.TP
+.B complete (TAB)
+Attempt to perform completion on the text before point.

+Control Sequence Indicator (CSI), usually ESC\-. If this sequence is
+bound to "\e", keys producing such sequences will have no effect
+unless explicitly bound to a readline command, instead of inserting
+stray characters into the editing buffer. This is unbound by default,
+but usually bound to ESC\-.
+.TP
+.B insert\-comment (M\-#)
+Without a numeric argument, the value of the readline
+.B comment\-begin
+variable is inserted at the beginning of the current line.
+If a numeric argument is supplied, this command acts as a toggle: if
+the characters at the beginning of the line do not match the value 
+of \fBcomment\-begin\fP, the value is inserted, otherwise 
+the characters in \fBcomment-begin\fP are deleted from the beginning of
+the line.
+In either case, the line is accepted as if a newline had been typed.
+The default value of
+.B comment\-begin
+makes the current line a shell comment.
+If a numeric argument causes the comment character to be removed, the line
+will be executed by the shell.
+.TP
+.B dump\-functions
+Print all of the functions and their key bindings to the
+readline output stream. If a numeric argument is supplied,
+the output is formatted in such a way that it can be made part
+of an \fIinputrc\fP file.
+.TP
+.B dump\-variables
+Print all of the settable variables and their values to the
+readline output stream. If a numeric argument is supplied,
+the output is formatted in such a way that it can be made part
+of an \fIinputrc\fP file.
+.TP
+.B dump\-macros
+Print all of the readline key sequences bound to macros and the
+strings they output. If a numeric argument is supplied,
+the output is formatted in such a way that it can be made part
+of an \fIinputrc\fP file.
+.TP
+.B emacs\-editing\-mode (C\-e)
+When in
+.B vi
+command mode, this causes a switch to
+.B emacs
+editing mode.
+.TP
+.B vi\-editing\-mode (M\-C\-j)
+When in
+.B emacs
+editing mode, this causes a switch to
+.B vi
+editing mode.
+.PD
+.SH DEFAULT KEY BINDINGS
+.LP
+The following is a list of the default emacs and vi bindings.
+Characters with the eighth bit set are written as M\-<character>, and
+are referred to as
+.I metafied
+characters.
+The printable ASCII characters not mentioned in the list of emacs
+standard bindings are bound to the
+.B self\-insert
+function, which just inserts the given character into the input line.
+In vi insertion mode, all characters not specifically mentioned are
+bound to
+.BR self\-insert .
+Characters assigned to signal generation by
+.IR stty (1)
+or the terminal driver, such as C-Z or C-C,
+retain that function.
+Upper and lower case metafied characters are bound to the same function in
+the emacs mode meta keymap.
+The remaining characters are unbound, which causes readline
+to ring the bell (subject to the setting of the
+.B bell\-style
+variable).

+<H2> 1.1 Introduction to Line Editing </H2>
+
+
+
+The following paragraphs describe the notation used to represent
+keystrokes.
+
+
+The text <KBD>C-k</KBD> is read as `Control-K' and describes the character
+produced when the <KBD>k</KBD> key is pressed while the Control key
+is depressed.
+
+
+The text <KBD>M-k</KBD> is read as `Meta-K' and describes the character
+produced when the Meta key (if you have one) is depressed, and the <KBD>k</KBD>
+key is pressed.
+The Meta key is labeled <KBD>ALT</KBD> on many keyboards.
+On keyboards with two keys labeled <KBD>ALT</KBD> (usually to either side of
+the space bar), the <KBD>ALT</KBD> on the left side is generally set to
+work as a Meta key.
+The <KBD>ALT</KBD> key on the right may also be configured to work as a
+Meta key or may be configured as some other modifier, such as a
+Compose key for typing accented characters.
+
+
+If you do not have a Meta or <KBD>ALT</KBD> key, or another key working as
+a Meta key, the identical keystroke can be generated by typing <KBD>ESC</KBD>
+first, and then typing <KBD>k</KBD>.
+Either process is known as metafying the <KBD>k</KBD> key.
+
+
+The text <KBD>M-C-k</KBD> is read as `Meta-Control-k' and describes the
+character produced by metafying <KBD>C-k</KBD>.
+
+
+In addition, several keys have their own names. Specifically,
+<KBD>DEL</KBD>, <KBD>ESC</KBD>, <KBD>LFD</KBD>, <KBD>SPC</KBD>, <KBD>RET</KBD>, and <KBD>TAB</KBD> all
+stand for themselves when seen in this text, or in an init file
+(see section <A HREF="readline.html#SEC9">1.3 Readline Init File</A>).
+If your keyboard lacks a <KBD>LFD</KBD> key, typing <KBD>C-j</KBD> will
+produce the desired character.
+The <KBD>RET</KBD> key may be labeled <KBD>Return</KBD> or <KBD>Enter</KBD> on
+some keyboards.

+<H2> 1.2 Readline Interaction </H2>
+
+
+
+Often during an interactive session you type in a long line of text,
+only to notice that the first word on the line is misspelled. The
+Readline library gives you a set of commands for manipulating the text
+as you type it in, allowing you to just fix your typo, and not forcing
+you to retype the majority of the line. Using these editing commands,
+you move the cursor to the place that needs correction, and delete or
+insert the text of the corrections. Then, when you are satisfied with
+the line, you simply press <KBD>RET</KBD>. You do not have to be at the
+end of the line to press <KBD>RET</KBD>; the entire line is accepted
+regardless of the location of the cursor within the line.

+<H3> 1.2.1 Readline Bare Essentials </H3>
+
+
+
+In order to enter characters into the line, simply type them. The typed
+character appears where the cursor was, and then the cursor moves one
+space to the right. If you mistype a character, you can use your
+erase character to back up and delete the mistyped character.
+
+
+Sometimes you may mistype a character, and
+not notice the error until you have typed several other characters. In
+that case, you can type <KBD>C-b</KBD> to move the cursor to the left, and then
+correct your mistake. Afterwards, you can move the cursor to the right
+with <KBD>C-f</KBD>.
+
+
+When you add text in the middle of a line, you will notice that characters
+to the right of the cursor are `pushed over' to make room for the text
+that you have inserted. Likewise, when you delete text behind the cursor,
+characters to the right of the cursor are `pulled back' to fill in the
+blank space created by the removal of the text. A list of the bare
+essentials for editing the text of an input line follows.
+

+<H3> 1.2.2 Readline Movement Commands </H3>
+
+
+
+The above table describes the most basic keystrokes that you need
+in order to do editing of the input line. For your convenience, many
+other commands have been added in addition to <KBD>C-b</KBD>, <KBD>C-f</KBD>,
+<KBD>C-d</KBD>, and <KBD>DEL</KBD>. Here are some commands for moving more rapidly
+about the line.
+
+
+<DL COMPACT>
+<DT><KBD>C-a</KBD>
+<DD>Move to the start of the line.
+<DT><KBD>C-e</KBD>
+<DD>Move to the end of the line.
+<DT><KBD>M-f</KBD>
+<DD>Move forward a word, where a word is composed of letters and digits.
+<DT><KBD>M-b</KBD>
+<DD>Move backward a word.
+<DT><KBD>C-l</KBD>
+<DD>Clear the screen, reprinting the current line at the top.
+</DL>
+
+
+Notice how <KBD>C-f</KBD> moves forward a character, while <KBD>M-f</KBD> moves
+forward a word. It is a loose convention that control keystrokes
+operate on characters while meta keystrokes operate on words.

+
+
+Killing text means to delete the text from the line, but to save
+it away for later use, usually by yanking (re-inserting)
+it back into the line.
+(`Cut' and `paste' are more recent jargon for `kill' and `yank'.)
+
+
+If the description for a command says that it `kills' text, then you can
+be sure that you can get the text back in a different (or the same)
+place later.
+
+
+When you use a kill command, the text is saved in a kill-ring.
+Any number of consecutive kills save all of the killed text together, so
+that when you yank it back, you get it all. The kill
+ring is not line specific; the text that you killed on a previously
+typed line is available to be yanked back later, when you are typing
+another line.
+<A NAME="IDX3"></A>
+
+
+Here is the list of commands for killing text.
+
+
+<DL COMPACT>
+<DT><KBD>C-k</KBD>
+<DD>Kill the text from the current cursor position to the end of the line.
+
+
+<DT><KBD>M-d</KBD>
+<DD>Kill from the cursor to the end of the current word, or, if between
+words, to the end of the next word.
+Word boundaries are the same as those used by <KBD>M-f</KBD>.
+
+
+<DT><KBD>M-<KBD>DEL</KBD></KBD>
+<DD>Kill from the cursor the start of the current word, or, if between
+words, to the start of the previous word.
+Word boundaries are the same as those used by <KBD>M-b</KBD>.
+
+
+<DT><KBD>C-w</KBD>
+<DD>Kill from the cursor to the previous whitespace. This is different than
+<KBD>M-<KBD>DEL</KBD></KBD> because the word boundaries differ.
+
+
+</DL>
+
+
+Here is how to yank the text back into the line. Yanking
+means to copy the most-recently-killed text from the kill buffer.
+
+
+<DL COMPACT>
+<DT><KBD>C-y</KBD>
+<DD>Yank the most recently killed text back into the buffer at the cursor.
+
+
+<DT><KBD>M-y</KBD>
+<DD>Rotate the kill-ring, and yank the new top. You can only do this if
+the prior command is <KBD>C-y</KBD> or <KBD>M-y</KBD>.

+<H3> 1.2.4 Readline Arguments </H3>
+
+
+
+You can pass numeric arguments to Readline commands. Sometimes the
+argument acts as a repeat count, other times it is the sign of the
+argument that is significant. If you pass a negative argument to a
+command which normally acts in a forward direction, that command will
+act in a backward direction. For example, to kill text back to the
+start of the line, you might type <SAMP>`M-- C-k'</SAMP>.
+
+
+The general way to pass numeric arguments to a command is to type meta
+digits before the command. If the first `digit' typed is a minus
+sign (<SAMP>`-'</SAMP>), then the sign of the argument will be negative. Once
+you have typed one meta digit to get the argument started, you can type
+the remainder of the digits, and then the command. For example, to give
+the <KBD>C-d</KBD> command an argument of 10, you could type <SAMP>`M-1 0 C-d'</SAMP>,
+which will delete the next ten characters on the input line.

+<H3> 1.2.5 Searching for Commands in the History </H3>
+
+
+
+Readline provides commands for searching through the command history
+for lines containing a specified string.
+There are two search modes: incremental and non-incremental.
+
+
+Incremental searches begin before the user has finished typing the
+search string.
+As each character of the search string is typed, Readline displays
+the next entry from the history matching the string typed so far.
+An incremental search requires only as many characters as needed to
+find the desired history entry.
+To search backward in the history for a particular string, type
+<KBD>C-r</KBD>. Typing <KBD>C-s</KBD> searches forward through the history.
+The characters present in the value of the <CODE>isearch-terminators</CODE> variable
+are used to terminate an incremental search.
+If that variable has not been assigned a value, the <KBD>ESC</KBD> and
+<KBD>C-J</KBD> characters will terminate an incremental search.
+<KBD>C-g</KBD> will abort an incremental search and restore the original line.
+When the search is terminated, the history entry containing the
+search string becomes the current line.
+
+
+To find other matching entries in the history list, type <KBD>C-r</KBD> or
+<KBD>C-s</KBD> as appropriate.
+This will search backward or forward in the history for the next
+entry matching the search string typed so far.
+Any other key sequence bound to a Readline command will terminate
+the search and execute that command.
+For instance, a <KBD>RET</KBD> will terminate the search and accept
+the line, thereby executing the command from the history list.
+A movement command will terminate the search, make the last line found
+the current line, and begin editing.
+
+
+Readline remembers the last incremental search string. If two
+<KBD>C-r</KBD>s are typed without any intervening characters defining a new
+search string, any remembered search string is used.
+
+
+Non-incremental searches read the entire search string before starting
+to search for matching history lines. The search string may be
+typed by the user or be part of the contents of the current line.

+<H2> 1.3 Readline Init File </H2>
+
+
+
+Although the Readline library comes with a set of Emacs-like
+keybindings installed by default, it is possible to use a different set
+of keybindings.
+Any user can customize programs that use Readline by putting
+commands in an inputrc file, conventionally in his home directory.
+The name of this
+file is taken from the value of the environment variable <CODE>INPUTRC</CODE>. If
+that variable is unset, the default is <TT>`~/.inputrc'</TT>. If that
+file does not exist or cannot be read, the ultimate default is
+<TT>`/etc/inputrc'</TT>.
+
+
+When a program which uses the Readline library starts up, the
+init file is read, and the key bindings are set.
+
+
+In addition, the <CODE>C-x C-r</CODE> command re-reads this init file, thus
+incorporating any changes that you might have made to it.

+<H3> 1.3.1 Readline Init File Syntax </H3>
+
+
+
+There are only a few basic constructs allowed in the
+Readline init file. Blank lines are ignored.
+Lines beginning with a <SAMP>`#'</SAMP> are comments.
+Lines beginning with a <SAMP>`$'</SAMP> indicate conditional
+constructs (see section <A HREF="readline.html#SEC11">1.3.2 Conditional Init Constructs</A>). Other lines
+denote variable settings and key bindings.
+
+
+<DL COMPACT>
+<DT>Variable Settings
+<DD>You can modify the run-time behavior of Readline by
+altering the values of variables in Readline
+using the <CODE>set</CODE> command within the init file.
+The syntax is simple:
+
+
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>set <VAR>variable</VAR> <VAR>value</VAR>
+</pre></td></tr></table>
+
+Here, for example, is how to
+change from the default Emacs-like key binding to use
+<CODE>vi</CODE> line editing commands:
+
+
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>set editing-mode vi
+</pre></td></tr></table>
+
+Variable names and values, where appropriate, are recognized without regard
+to case. Unrecognized variable names are ignored.
+
+
+Boolean variables (those that can be set to on or off) are set to on if
+the value is null or empty, <VAR>on</VAR> (case-insensitive), or 1. Any other
+value results in the variable being set to off.
+
+
+A great deal of run-time behavior is changeable with the following
+variables.
+
+
+<A NAME="IDX4"></A>
+<DL COMPACT>
+
+<DT><CODE>bell-style</CODE>
+<DD><A NAME="IDX5"></A>
+Controls what happens when Readline wants to ring the terminal bell.
+If set to <SAMP>`none'</SAMP>, Readline never rings the bell. If set to
+<SAMP>`visible'</SAMP>, Readline uses a visible bell if one is available.
+If set to <SAMP>`audible'</SAMP> (the default), Readline attempts to ring
+the terminal's bell.
+
+
+<DT><CODE>bind-tty-special-chars</CODE>
+<DD><A NAME="IDX6"></A>
+If set to <SAMP>`on'</SAMP> (the default), Readline attempts to bind the control
+characters treated specially by the kernel's terminal driver to their
+Readline equivalents.
+
+
+<DT><CODE>blink-matching-paren</CODE>
+<DD><A NAME="IDX7"></A>
+If set to <SAMP>`on'</SAMP>, Readline attempts to briefly move the cursor to an
+opening parenthesis when a closing parenthesis is inserted. The default
+is <SAMP>`off'</SAMP>.
+
+
+<DT><CODE>colored-completion-prefix</CODE>
+<DD><A NAME="IDX8"></A>
+If set to <SAMP>`on'</SAMP>, when listing completions, Readline displays the
+common prefix of the set of possible completions using a different color.
+The color definitions are taken from the value of the <CODE>LS_COLORS</CODE>
+environment variable.
+The default is <SAMP>`off'</SAMP>.
+
+
+<DT><CODE>colored-stats</CODE>
+<DD><A NAME="IDX9"></A>
+If set to <SAMP>`on'</SAMP>, Readline displays possible completions using different
+colors to indicate their file type.
+The color definitions are taken from the value of the <CODE>LS_COLORS</CODE>
+environment variable.
+The default is <SAMP>`off'</SAMP>.
+
+
+<DT><CODE>comment-begin</CODE>
+<DD><A NAME="IDX10"></A>
+The string to insert at the beginning of the line when the
+<CODE>insert-comment</CODE> command is executed. The default value
+is <CODE>"#"</CODE>.
+
+
+<DT><CODE>completion-display-width</CODE>
+<DD><A NAME="IDX11"></A>
+The number of screen columns used to display possible matches
+when performing completion.
+The value is ignored if it is less than 0 or greater than the terminal
+screen width.
+A value of 0 will cause matches to be displayed one per line.
+The default value is -1.
+
+
+<DT><CODE>completion-ignore-case</CODE>
+<DD><A NAME="IDX12"></A>
+If set to <SAMP>`on'</SAMP>, Readline performs filename matching and completion
+in a case-insensitive fashion.
+The default value is <SAMP>`off'</SAMP>.
+
+
+<DT><CODE>completion-map-case</CODE>
+<DD><A NAME="IDX13"></A>
+If set to <SAMP>`on'</SAMP>, and <VAR>completion-ignore-case</VAR> is enabled, Readline
+treats hyphens (<SAMP>`-'</SAMP>) and underscores (<SAMP>`_'</SAMP>) as equivalent when
+performing case-insensitive filename matching and completion.
+The default value is <SAMP>`off'</SAMP>.
+
+
+<DT><CODE>completion-prefix-display-length</CODE>
+<DD><A NAME="IDX14"></A>
+The length in characters of the common prefix of a list of possible
+completions that is displayed without modification. When set to a
+value greater than zero, common prefixes longer than this value are
+replaced with an ellipsis when displaying possible completions.
+
+
+<DT><CODE>completion-query-items</CODE>
+<DD><A NAME="IDX15"></A>
+The number of possible completions that determines when the user is
+asked whether the list of possibilities should be displayed.
+If the number of possible completions is greater than or equal to this value,
+Readline will ask whether or not the user wishes to view them;
+otherwise, they are simply listed.
+This variable must be set to an integer value greater than or equal to 0.
+A negative value means Readline should never ask.
+The default limit is <CODE>100</CODE>.
+
+
+<DT><CODE>convert-meta</CODE>
+<DD><A NAME="IDX16"></A>
+If set to <SAMP>`on'</SAMP>, Readline will convert characters with the
+eighth bit set to an ASCII key sequence by stripping the eighth
+bit and prefixing an <KBD>ESC</KBD> character, converting them to a
+meta-prefixed key sequence. The default value is <SAMP>`on'</SAMP>, but
+will be set to <SAMP>`off'</SAMP> if the locale is one that contains
+eight-bit characters.
+
+
+<DT><CODE>disable-completion</CODE>
+<DD><A NAME="IDX17"></A>
+If set to <SAMP>`On'</SAMP>, Readline will inhibit word completion.
+Completion characters will be inserted into the line as if they had
+been mapped to <CODE>self-insert</CODE>. The default is <SAMP>`off'</SAMP>.
+
+
+<DT><CODE>echo-control-characters</CODE>
+<DD><A NAME="IDX18"></A>
+When set to <SAMP>`on'</SAMP>, on operating systems that indicate they support it,
+readline echoes a character corresponding to a signal generated from the
+keyboard. The default is <SAMP>`on'</SAMP>.
+
+
+<DT><CODE>editing-mode</CODE>
+<DD><A NAME="IDX19"></A>
+The <CODE>editing-mode</CODE> variable controls which default set of
+key bindings is used. By default, Readline starts up in Emacs editing
+mode, where the keystrokes are most similar to Emacs. This variable can be
+set to either <SAMP>`emacs'</SAMP> or <SAMP>`vi'</SAMP>.
+
+
+<DT><CODE>emacs-mode-string</CODE>
+<DD><A NAME="IDX20"></A>
+If the <VAR>show-mode-in-prompt</VAR> variable is enabled,
+this string is displayed immediately before the last line of the primary
+prompt when emacs editing mode is active. The value is expanded like a
+key binding, so the standard set of meta- and control prefixes and
+backslash escape sequences is available.
+Use the <SAMP>`\1'</SAMP> and <SAMP>`\2'</SAMP> escapes to begin and end sequences of
+non-printing characters, which can be used to embed a terminal control
+sequence into the mode string.
+The default is <SAMP>`@'</SAMP>.
+
+
+<DT><CODE>enable-bracketed-paste</CODE>
+<DD><A NAME="IDX21"></A>
+When set to <SAMP>`On'</SAMP>, Readline will configure the terminal in a way
+that will enable it to insert each paste into the editing buffer as a
+single string of characters, instead of treating each character as if
+it had been read from the keyboard. This can prevent pasted characters
+from being interpreted as editing commands. The default is <SAMP>`On'</SAMP>.
+
+
+<DT><CODE>enable-keypad</CODE>
+<DD><A NAME="IDX22"></A>
+When set to <SAMP>`on'</SAMP>, Readline will try to enable the application
+keypad when it is called. Some systems need this to enable the
+arrow keys. The default is <SAMP>`off'</SAMP>.
+
+
+<DT><CODE>enable-meta-key</CODE>
+<DD>When set to <SAMP>`on'</SAMP>, Readline will try to enable any meta modifier
+key the terminal claims to support when it is called. On many terminals,
+the meta key is used to send eight-bit characters.
+The default is <SAMP>`on'</SAMP>.
+
+
+<DT><CODE>expand-tilde</CODE>
+<DD><A NAME="IDX23"></A>
+If set to <SAMP>`on'</SAMP>, tilde expansion is performed when Readline
+attempts word completion. The default is <SAMP>`off'</SAMP>.
+
+
+<DT><CODE>history-preserve-point</CODE>
+<DD><A NAME="IDX24"></A>
+If set to <SAMP>`on'</SAMP>, the history code attempts to place the point (the
+current cursor position) at the
+same location on each history line retrieved with <CODE>previous-history</CODE>
+or <CODE>next-history</CODE>. The default is <SAMP>`off'</SAMP>.
+
+
+<DT><CODE>history-size</CODE>
+<DD><A NAME="IDX25"></A>
+Set the maximum number of history entries saved in the history list.
+If set to zero, any existing history entries are deleted and no new entries
+are saved.
+If set to a value less than zero, the number of history entries is not
+limited.
+By default, the number of history entries is not limited.
+If an attempt is made to set <VAR>history-size</VAR> to a non-numeric value,
+the maximum number of history entries will be set to 500.
+
+
+<DT><CODE>horizontal-scroll-mode</CODE>
+<DD><A NAME="IDX26"></A>
+This variable can be set to either <SAMP>`on'</SAMP> or <SAMP>`off'</SAMP>. Setting it
+to <SAMP>`on'</SAMP> means that the text of the lines being edited will scroll
+horizontally on a single screen line when they are longer than the width
+of the screen, instead of wrapping onto a new screen line.
+This variable is automatically set to <SAMP>`on'</SAMP> for terminals of height 1.
+By default, this variable is set to <SAMP>`off'</SAMP>.
+
+
+<DT><CODE>input-meta</CODE>
+<DD><A NAME="IDX27"></A>
+<A NAME="IDX28"></A>
+If set to <SAMP>`on'</SAMP>, Readline will enable eight-bit input (it
+will not clear the eighth bit in the characters it reads),
+regardless of what the terminal claims it can support. The
+default value is <SAMP>`off'</SAMP>, but Readline will set it to <SAMP>`on'</SAMP> if the 
+locale contains eight-bit characters.
+The name <CODE>meta-flag</CODE> is a synonym for this variable.
+
+
+<DT><CODE>isearch-terminators</CODE>
+<DD><A NAME="IDX29"></A>
+The string of characters that should terminate an incremental search without
+subsequently executing the character as a command (see section <A HREF="readline.html#SEC8">1.2.5 Searching for Commands in the History</A>).
+If this variable has not been given a value, the characters <KBD>ESC</KBD> and
+<KBD>C-J</KBD> will terminate an incremental search.
+
+
+<DT><CODE>keymap</CODE>
+<DD><A NAME="IDX30"></A>
+Sets Readline's idea of the current keymap for key binding commands.
+Built-in <CODE>keymap</CODE> names are
+<CODE>emacs</CODE>,
+<CODE>emacs-standard</CODE>,
+<CODE>emacs-meta</CODE>,
+<CODE>emacs-ctlx</CODE>,
+<CODE>vi</CODE>,
+<CODE>vi-move</CODE>,
+<CODE>vi-command</CODE>, and
+<CODE>vi-insert</CODE>.
+<CODE>vi</CODE> is equivalent to <CODE>vi-command</CODE> (<CODE>vi-move</CODE> is also a
+synonym); <CODE>emacs</CODE> is equivalent to <CODE>emacs-standard</CODE>.
+Applications may add additional names.
+The default value is <CODE>emacs</CODE>.
+The value of the <CODE>editing-mode</CODE> variable also affects the
+default keymap.
+
+
+<DT><CODE>keyseq-timeout</CODE>
+<DD>Specifies the duration Readline will wait for a character when reading an
+ambiguous key sequence (one that can form a complete key sequence using
+the input read so far, or can take additional input to complete a longer
+key sequence).
+If no input is received within the timeout, Readline will use the shorter
+but complete key sequence.
+Readline uses this value to determine whether or not input is
+available on the current input source (<CODE>rl_instream</CODE> by default).
+The value is specified in milliseconds, so a value of 1000 means that
+Readline will wait one second for additional input.
+If this variable is set to a value less than or equal to zero, or to a
+non-numeric value, Readline will wait until another key is pressed to
+decide which key sequence to complete.
+The default value is <CODE>500</CODE>.
+
+
+<DT><CODE>mark-directories</CODE>
+<DD>If set to <SAMP>`on'</SAMP>, completed directory names have a slash
+appended. The default is <SAMP>`on'</SAMP>.
+
+
+<DT><CODE>mark-modified-lines</CODE>
+<DD><A NAME="IDX31"></A>
+This variable, when set to <SAMP>`on'</SAMP>, causes Readline to display an
+asterisk (<SAMP>`*'</SAMP>) at the start of history lines which have been modified.
+This variable is <SAMP>`off'</SAMP> by default.
+
+
+<DT><CODE>mark-symlinked-directories</CODE>
+<DD><A NAME="IDX32"></A>
+If set to <SAMP>`on'</SAMP>, completed names which are symbolic links
+to directories have a slash appended (subject to the value of
+<CODE>mark-directories</CODE>).
+The default is <SAMP>`off'</SAMP>.
+
+
+<DT><CODE>match-hidden-files</CODE>
+<DD><A NAME="IDX33"></A>
+This variable, when set to <SAMP>`on'</SAMP>, causes Readline to match files whose
+names begin with a <SAMP>`.'</SAMP> (hidden files) when performing filename
+completion.
+If set to <SAMP>`off'</SAMP>, the leading <SAMP>`.'</SAMP> must be
+supplied by the user in the filename to be completed.
+This variable is <SAMP>`on'</SAMP> by default.
+
+
+<DT><CODE>menu-complete-display-prefix</CODE>
+<DD><A NAME="IDX34"></A>
+If set to <SAMP>`on'</SAMP>, menu completion displays the common prefix of the
+list of possible completions (which may be empty) before cycling through
+the list. The default is <SAMP>`off'</SAMP>.
+
+
+<DT><CODE>output-meta</CODE>
+<DD><A NAME="IDX35"></A>
+If set to <SAMP>`on'</SAMP>, Readline will display characters with the
+eighth bit set directly rather than as a meta-prefixed escape
+sequence.
+The default is <SAMP>`off'</SAMP>, but Readline will set it to <SAMP>`on'</SAMP> if the
+locale contains eight-bit characters.
+
+
+<DT><CODE>page-completions</CODE>
+<DD><A NAME="IDX36"></A>
+If set to <SAMP>`on'</SAMP>, Readline uses an internal <CODE>more</CODE>-like pager
+to display a screenful of possible completions at a time.
+This variable is <SAMP>`on'</SAMP> by default.
+
+
+<DT><CODE>print-completions-horizontally</CODE>
+<DD>If set to <SAMP>`on'</SAMP>, Readline will display completions with matches
+sorted horizontally in alphabetical order, rather than down the screen.
+The default is <SAMP>`off'</SAMP>.
+
+
+<DT><CODE>revert-all-at-newline</CODE>
+<DD><A NAME="IDX37"></A>
+If set to <SAMP>`on'</SAMP>, Readline will undo all changes to history lines
+before returning when <CODE>accept-line</CODE> is executed. By default,
+history lines may be modified and retain individual undo lists across
+calls to <CODE>readline</CODE>. The default is <SAMP>`off'</SAMP>.
+
+
+<DT><CODE>show-all-if-ambiguous</CODE>
+<DD><A NAME="IDX38"></A>
+This alters the default behavior of the completion functions. If
+set to <SAMP>`on'</SAMP>, 
+words which have more than one possible completion cause the
+matches to be listed immediately instead of ringing the bell.
+The default value is <SAMP>`off'</SAMP>.
+
+
+<DT><CODE>show-all-if-unmodified</CODE>
+<DD><A NAME="IDX39"></A>
+This alters the default behavior of the completion functions in
+a fashion similar to <VAR>show-all-if-ambiguous</VAR>.
+If set to <SAMP>`on'</SAMP>, 
+words which have more than one possible completion without any
+possible partial completion (the possible completions don't share
+a common prefix) cause the matches to be listed immediately instead
+of ringing the bell.
+The default value is <SAMP>`off'</SAMP>.
+
+
+<DT><CODE>show-mode-in-prompt</CODE>
+<DD><A NAME="IDX40"></A>
+If set to <SAMP>`on'</SAMP>, add a string to the beginning of the prompt
+indicating the editing mode: emacs, vi command, or vi insertion.
+The mode strings are user-settable (e.g., <VAR>emacs-mode-string</VAR>).
+The default value is <SAMP>`off'</SAMP>.
+
+
+<DT><CODE>skip-completed-text</CODE>
+<DD><A NAME="IDX41"></A>
+If set to <SAMP>`on'</SAMP>, this alters the default completion behavior when
+inserting a single match into the line. It's only active when
+performing completion in the middle of a word. If enabled, readline
+does not insert characters from the completion that match characters
+after point in the word being completed, so portions of the word
+following the cursor are not duplicated.
+For instance, if this is enabled, attempting completion when the cursor
+is after the <SAMP>`e'</SAMP> in <SAMP>`Makefile'</SAMP> will result in <SAMP>`Makefile'</SAMP>
+rather than <SAMP>`Makefilefile'</SAMP>, assuming there is a single possible
+completion.
+The default value is <SAMP>`off'</SAMP>.
+
+
+<DT><CODE>vi-cmd-mode-string</CODE>
+<DD><A NAME="IDX42"></A>
+If the <VAR>show-mode-in-prompt</VAR> variable is enabled,
+this string is displayed immediately before the last line of the primary
+prompt when vi editing mode is active and in command mode.
+The value is expanded like a
+key binding, so the standard set of meta- and control prefixes and
+backslash escape sequences is available.
+Use the <SAMP>`\1'</SAMP> and <SAMP>`\2'</SAMP> escapes to begin and end sequences of
+non-printing characters, which can be used to embed a terminal control
+sequence into the mode string.
+The default is <SAMP>`(cmd)'</SAMP>.
+
+
+<DT><CODE>vi-ins-mode-string</CODE>
+<DD><A NAME="IDX43"></A>
+If the <VAR>show-mode-in-prompt</VAR> variable is enabled,
+this string is displayed immediately before the last line of the primary
+prompt when vi editing mode is active and in insertion mode.
+The value is expanded like a
+key binding, so the standard set of meta- and control prefixes and
+backslash escape sequences is available.
+Use the <SAMP>`\1'</SAMP> and <SAMP>`\2'</SAMP> escapes to begin and end sequences of
+non-printing characters, which can be used to embed a terminal control
+sequence into the mode string.
+The default is <SAMP>`(ins)'</SAMP>.
+
+
+<DT><CODE>visible-stats</CODE>
+<DD><A NAME="IDX44"></A>
+If set to <SAMP>`on'</SAMP>, a character denoting a file's type
+is appended to the filename when listing possible
+completions. The default is <SAMP>`off'</SAMP>.
+
+
+</DL>
+
+
+<DT>Key Bindings
+<DD>The syntax for controlling key bindings in the init file is
+simple. First you need to find the name of the command that you
+want to change. The following sections contain tables of the command
+name, the default keybinding, if any, and a short description of what
+the command does.
+
+
+Once you know the name of the command, simply place on a line
+in the init file the name of the key
+you wish to bind the command to, a colon, and then the name of the
+command.
+There can be no space between the key name and the colon -- that will be
+interpreted as part of the key name.
+The name of the key can be expressed in different ways, depending on
+what you find most comfortable.
+
+
+In addition to command names, readline allows keys to be bound
+to a string that is inserted when the key is pressed (a <VAR>macro</VAR>).
+
+
+<DL COMPACT>
+<DT><VAR>keyname</VAR>: <VAR>function-name</VAR> or <VAR>macro</VAR>
+<DD><VAR>keyname</VAR> is the name of a key spelled out in English. For example:
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>Control-u: universal-argument
+Meta-Rubout: backward-kill-word
+Control-o: "&#62; output"
+</pre></td></tr></table>
+
+In the example above, <KBD>C-u</KBD> is bound to the function
+<CODE>universal-argument</CODE>,
+<KBD>M-DEL</KBD> is bound to the function <CODE>backward-kill-word</CODE>, and
+<KBD>C-o</KBD> is bound to run the macro
+expressed on the right hand side (that is, to insert the text
+<SAMP>`&#62; output'</SAMP> into the line).
+
+
+A number of symbolic character names are recognized while
+processing this key binding syntax:
+<VAR>DEL</VAR>,
+<VAR>ESC</VAR>,
+<VAR>ESCAPE</VAR>,
+<VAR>LFD</VAR>,
+<VAR>NEWLINE</VAR>,
+<VAR>RET</VAR>,
+<VAR>RETURN</VAR>,
+<VAR>RUBOUT</VAR>,
+<VAR>SPACE</VAR>,
+<VAR>SPC</VAR>,
+and
+<VAR>TAB</VAR>.
+
+
+<DT>"<VAR>keyseq</VAR>": <VAR>function-name</VAR> or <VAR>macro</VAR>
+<DD><VAR>keyseq</VAR> differs from <VAR>keyname</VAR> above in that strings
+denoting an entire key sequence can be specified, by placing
+the key sequence in double quotes. Some GNU Emacs style key
+escapes can be used, as in the following example, but the
+special character names are not recognized.
+
+
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>"\C-u": universal-argument
+"\C-x\C-r": re-read-init-file
+"\e11~": "Function Key 1"
+</pre></td></tr></table>
+
+In the above example, <KBD>C-u</KBD> is again bound to the function
+<CODE>universal-argument</CODE> (just as it was in the first example),
+<SAMP>`<KBD>C-x</KBD> <KBD>C-r</KBD>'</SAMP> is bound to the function <CODE>re-read-init-file</CODE>,
+and <SAMP>`<KBD>ESC</KBD> <KBD></KBD> <KBD>1</KBD> <KBD>1</KBD> <KBD>~</KBD>'</SAMP> is bound to insert
+the text <SAMP>`Function Key 1'</SAMP>.
+
+
+</DL>
+
+
+The following GNU Emacs style escape sequences are available when
+specifying key sequences:
+
+
+<DL COMPACT>
+<DT><CODE><KBD>\C-</KBD></CODE>
+<DD>control prefix
+<DT><CODE><KBD>\M-</KBD></CODE>
+<DD>meta prefix
+<DT><CODE><KBD>\e</KBD></CODE>
+<DD>an escape character
+<DT><CODE><KBD>\\</KBD></CODE>
+<DD>backslash
+<DT><CODE><KBD>\"</KBD></CODE>
+<DD><KBD>"</KBD>, a double quotation mark
+<DT><CODE><KBD>\'</KBD></CODE>
+<DD><KBD>'</KBD>, a single quote or apostrophe
+</DL>
+
+
+In addition to the GNU Emacs style escape sequences, a second
+set of backslash escapes is available:
+
+
+<DL COMPACT>
+<DT><CODE>\a</CODE>
+<DD>alert (bell)
+<DT><CODE>\b</CODE>
+<DD>backspace
+<DT><CODE>\d</CODE>
+<DD>delete
+<DT><CODE>\f</CODE>
+<DD>form feed
+<DT><CODE>\n</CODE>
+<DD>newline
+<DT><CODE>\r</CODE>
+<DD>carriage return
+<DT><CODE>\t</CODE>
+<DD>horizontal tab
+<DT><CODE>\v</CODE>
+<DD>vertical tab
+<DT><CODE>\<VAR>nnn</VAR></CODE>
+<DD>the eight-bit character whose value is the octal value <VAR>nnn</VAR>
+(one to three digits)
+<DT><CODE>\x<VAR>HH</VAR></CODE>
+<DD>the eight-bit character whose value is the hexadecimal value <VAR>HH</VAR>
+(one or two hex digits)
+</DL>
+
+
+When entering the text of a macro, single or double quotes must
+be used to indicate a macro definition.
+Unquoted text is assumed to be a function name.
+In the macro body, the backslash escapes described above are expanded.
+Backslash will quote any other character in the macro text,
+including <SAMP>`"'</SAMP> and <SAMP>`''</SAMP>.
+For example, the following binding will make <SAMP>`<KBD>C-x</KBD> \'</SAMP>
+insert a single <SAMP>`\'</SAMP> into the line:
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>"\C-x\\": "\\"

+<H3> 1.3.2 Conditional Init Constructs </H3>
+
+
+
+Readline implements a facility similar in spirit to the conditional
+compilation features of the C preprocessor which allows key
+bindings and variable settings to be performed as the result
+of tests. There are four parser directives used.
+
+
+<DL COMPACT>
+<DT><CODE>$if</CODE>
+<DD>The <CODE>$if</CODE> construct allows bindings to be made based on the
+editing mode, the terminal being used, or the application using
+Readline. The text of the test, after any comparison operator,
+extends to the end of the line;
+unless otherwise noted, no characters are required to isolate it.
+
+
+<DL COMPACT>
+<DT><CODE>mode</CODE>
+<DD>The <CODE>mode=</CODE> form of the <CODE>$if</CODE> directive is used to test
+whether Readline is in <CODE>emacs</CODE> or <CODE>vi</CODE> mode.
+This may be used in conjunction
+with the <SAMP>`set keymap'</SAMP> command, for instance, to set bindings in
+the <CODE>emacs-standard</CODE> and <CODE>emacs-ctlx</CODE> keymaps only if
+Readline is starting out in <CODE>emacs</CODE> mode.
+
+
+<DT><CODE>term</CODE>
+<DD>The <CODE>term=</CODE> form may be used to include terminal-specific
+key bindings, perhaps to bind the key sequences output by the
+terminal's function keys. The word on the right side of the
+<SAMP>`='</SAMP> is tested against both the full name of the terminal and
+the portion of the terminal name before the first <SAMP>`-'</SAMP>. This
+allows <CODE>sun</CODE> to match both <CODE>sun</CODE> and <CODE>sun-cmd</CODE>,
+for instance.
+
+
+<DT><CODE>version</CODE>
+<DD>The <CODE>version</CODE> test may be used to perform comparisons against
+specific Readline versions.
+The <CODE>version</CODE> expands to the current Readline version.
+The set of comparison operators includes
+<SAMP>`='</SAMP> (and <SAMP>`=='</SAMP>), <SAMP>`!='</SAMP>, <SAMP>`&#60;='</SAMP>, <SAMP>`&#62;='</SAMP>, <SAMP>`&#60;'</SAMP>,
+and <SAMP>`&#62;'</SAMP>.
+The version number supplied on the right side of the operator consists
+of a major version number, an optional decimal point, and an optional
+minor version (e.g., <SAMP>`7.1'</SAMP>). If the minor version is omitted, it
+is assumed to be <SAMP>`0'</SAMP>.
+The operator may be separated from the string <CODE>version</CODE> and
+from the version number argument by whitespace.
+The following example sets a variable if the Readline version being used
+is 7.0 or newer:
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>$if version &#62;= 7.0
+set show-mode-in-prompt on
+$endif
+</pre></td></tr></table>
+
+<DT><CODE>application</CODE>
+<DD>The <VAR>application</VAR> construct is used to include
+application-specific settings. Each program using the Readline
+library sets the <VAR>application name</VAR>, and you can test for
+a particular value. 
+This could be used to bind key sequences to functions useful for
+a specific program. For instance, the following command adds a
+key sequence that quotes the current or previous word in Bash:
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>$if Bash
+# Quote the current or previous word
+"\C-xq": "\eb\"\ef\""
+$endif
+</pre></td></tr></table>
+
+<DT><CODE>variable</CODE>
+<DD>The <VAR>variable</VAR> construct provides simple equality tests for Readline
+variables and values.
+The permitted comparison operators are <SAMP>`='</SAMP>, <SAMP>`=='</SAMP>, and <SAMP>`!='</SAMP>.
+The variable name must be separated from the comparison operator by
+whitespace; the operator may be separated from the value on the right hand
+side by whitespace.
+Both string and boolean variables may be tested. Boolean variables must be
+tested against the values <VAR>on</VAR> and <VAR>off</VAR>.
+The following example is equivalent to the <CODE>mode=emacs</CODE> test described
+above:
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>$if editing-mode == emacs
+set show-mode-in-prompt on
+$endif
+</pre></td></tr></table></DL>
+
+
+<DT><CODE>$endif</CODE>
+<DD>This command, as seen in the previous example, terminates an
+<CODE>$if</CODE> command.
+
+
+<DT><CODE>$else</CODE>
+<DD>Commands in this branch of the <CODE>$if</CODE> directive are executed if
+the test fails.
+
+
+<DT><CODE>$include</CODE>
+<DD>This directive takes a single filename as an argument and reads commands
+and bindings from that file.
+For example, the following directive reads from <TT>`/etc/inputrc'</TT>:
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>$include /etc/inputrc
+</pre></td></tr></table></DL>

+
+
+<A NAME="IDX87"></A>
+<DT><CODE>history-search-backward ()</CODE>
+<DD><A NAME="IDX88"></A>
+Search backward through the history for the string of characters
+between the start of the current line and the point.
+The search string must match at the beginning of a history line.
+This is a non-incremental search.
+By default, this command is unbound.

+
+
+<A NAME="IDX91"></A>
+<DT><CODE>history-substring-search-backward ()</CODE>
+<DD><A NAME="IDX92"></A>
+Search backward through the history for the string of characters

+<DT><CODE>yank-nth-arg (M-C-y)</CODE>
+<DD><A NAME="IDX94"></A>
+Insert the first argument to the previous command (usually
+the second word on the previous line) at point.
+With an argument <VAR>n</VAR>,
+insert the <VAR>n</VAR>th word from the previous command (the words
+in the previous command begin with word 0). A negative argument
+inserts the <VAR>n</VAR>th word from the end of the previous command.
+Once the argument <VAR>n</VAR> is computed, the argument is extracted
+as if the <SAMP>`!<VAR>n</VAR>'</SAMP> history expansion had been specified.
+
+
+<A NAME="IDX95"></A>
+<DT><CODE>yank-last-arg (M-. or M-_)</CODE>
+<DD><A NAME="IDX96"></A>
+Insert last argument to the previous command (the last word of the
+previous history entry).
+With a numeric argument, behave exactly like <CODE>yank-nth-arg</CODE>.
+Successive calls to <CODE>yank-last-arg</CODE> move back through the history
+list, inserting the last word (or the word specified by the argument to
+the first call) of each line in turn.
+Any numeric argument supplied to these successive calls determines
+the direction to move through the history. A negative argument switches
+the direction through the history (back or forward).
+The history expansion facilities are used to extract the last argument,
+as if the <SAMP>`!$'</SAMP> history expansion had been specified.
+
+
+<A NAME="IDX97"></A>
+<DT><CODE>operate-and-get-next (C-o)</CODE>
+<DD><A NAME="IDX98"></A>
+Accept the current line for return to the calling application as if a
+newline had been entered,
+and fetch the next line relative to the current line from the history
+for editing.
+A numeric argument, if supplied, specifies the history entry to use instead
+of the current line.

+
+
+
+<DL COMPACT>
+
+<A NAME="IDX99"></A>
+<DT><CODE>end-of-file (usually C-d)</CODE>
+<DD><A NAME="IDX100"></A>
+The character indicating end-of-file as set, for example, by
+<CODE>stty</CODE>. If this character is read when there are no characters
+on the line, and point is at the beginning of the line, Readline
+interprets it as the end of input and returns EOF.
+
+
+<A NAME="IDX101"></A>
+<DT><CODE>delete-char (C-d)</CODE>
+<DD><A NAME="IDX102"></A>
+Delete the character at point. If this function is bound to the
+same character as the tty EOF character, as <KBD>C-d</KBD>
+commonly is, see above for the effects.
+
+
+<A NAME="IDX103"></A>
+<DT><CODE>backward-delete-char (Rubout)</CODE>
+<DD><A NAME="IDX104"></A>
+Delete the character behind the cursor. A numeric argument means
+to kill the characters instead of deleting them.
+
+
+<A NAME="IDX105"></A>
+<DT><CODE>forward-backward-delete-char ()</CODE>
+<DD><A NAME="IDX106"></A>
+Delete the character under the cursor, unless the cursor is at the
+end of the line, in which case the character behind the cursor is
+deleted. By default, this is not bound to a key.
+
+
+<A NAME="IDX107"></A>
+<DT><CODE>quoted-insert (C-q or C-v)</CODE>
+<DD><A NAME="IDX108"></A>
+Add the next character typed to the line verbatim. This is
+how to insert key sequences like <KBD>C-q</KBD>, for example.
+
+
+<A NAME="IDX109"></A>
+<DT><CODE>tab-insert (M-<KBD>TAB</KBD>)</CODE>
+<DD><A NAME="IDX110"></A>
+Insert a tab character.
+
+
+<A NAME="IDX111"></A>
+<DT><CODE>self-insert (a, b, A, 1, !, ...)</CODE>
+<DD><A NAME="IDX112"></A>
+Insert yourself.
+
+
+<A NAME="IDX113"></A>
+<DT><CODE>bracketed-paste-begin ()</CODE>
+<DD><A NAME="IDX114"></A>
+This function is intended to be bound to the "bracketed paste" escape
+sequence sent by some terminals, and such a binding is assigned by default.
+It allows Readline to insert the pasted text as a single unit without treating
+each character as if it had been read from the keyboard. The characters
+are inserted as if each one was bound to <CODE>self-insert</CODE> instead of
+executing any editing commands.
+
+
+Bracketed paste sets the region (the characters between point and the mark)
+to the inserted text. It uses the concept of an active mark: when the
+mark is active, Readline redisplay uses the terminal's standout mode to
+denote the region.
+
+
+<A NAME="IDX115"></A>
+<DT><CODE>transpose-chars (C-t)</CODE>
+<DD><A NAME="IDX116"></A>
+Drag the character before the cursor forward over
+the character at the cursor, moving the
+cursor forward as well. If the insertion point
+is at the end of the line, then this
+transposes the last two characters of the line.
+Negative arguments have no effect.
+
+
+<A NAME="IDX117"></A>
+<DT><CODE>transpose-words (M-t)</CODE>
+<DD><A NAME="IDX118"></A>
+Drag the word before point past the word after point,
+moving point past that word as well.
+If the insertion point is at the end of the line, this transposes
+the last two words on the line.
+
+
+<A NAME="IDX119"></A>
+<DT><CODE>upcase-word (M-u)</CODE>
+<DD><A NAME="IDX120"></A>
+Uppercase the current (or following) word. With a negative argument,
+uppercase the previous word, but do not move the cursor.
+
+
+<A NAME="IDX121"></A>
+<DT><CODE>downcase-word (M-l)</CODE>
+<DD><A NAME="IDX122"></A>
+Lowercase the current (or following) word. With a negative argument,
+lowercase the previous word, but do not move the cursor.
+
+
+<A NAME="IDX123"></A>
+<DT><CODE>capitalize-word (M-c)</CODE>
+<DD><A NAME="IDX124"></A>
+Capitalize the current (or following) word. With a negative argument,
+capitalize the previous word, but do not move the cursor.
+
+
+<A NAME="IDX125"></A>
+<DT><CODE>overwrite-mode ()</CODE>
+<DD><A NAME="IDX126"></A>
+Toggle overwrite mode. With an explicit positive numeric argument,
+switches to overwrite mode. With an explicit non-positive numeric
+argument, switches to insert mode. This command affects only
+<CODE>emacs</CODE> mode; <CODE>vi</CODE> mode does overwrite differently.
+Each call to <CODE>readline()</CODE> starts in insert mode.
+
+
+In overwrite mode, characters bound to <CODE>self-insert</CODE> replace
+the text at point rather than pushing the text to the right.
+Characters bound to <CODE>backward-delete-char</CODE> replace the character
+before point with a space.
+
+
+By default, this command is unbound.

+<H2> 1.5 Readline vi Mode </H2>
+
+
+
+While the Readline library does not have a full set of <CODE>vi</CODE>
+editing functions, it does contain enough to allow simple editing
+of the line. The Readline <CODE>vi</CODE> mode behaves as specified in
+the POSIX standard.
+
+
+In order to switch interactively between <CODE>emacs</CODE> and <CODE>vi</CODE>
+editing modes, use the command <KBD>M-C-j</KBD> (bound to emacs-editing-mode
+when in <CODE>vi</CODE> mode and to vi-editing-mode in <CODE>emacs</CODE> mode).
+The Readline default is <CODE>emacs</CODE> mode.
+
+
+When you enter a line in <CODE>vi</CODE> mode, you are already placed in
+`insertion' mode, as if you had typed an <SAMP>`i'</SAMP>. Pressing <KBD>ESC</KBD>
+switches you into `command' mode, where you can edit the text of the
+line with the standard <CODE>vi</CODE> movement keys, move to previous
+history lines with <SAMP>`k'</SAMP> and subsequent lines with <SAMP>`j'</SAMP>, and
+so forth.

+<H2> 2.1 Basic Behavior </H2>
+
+
+
+Many programs provide a command line interface, such as <CODE>mail</CODE>,
+<CODE>ftp</CODE>, and <CODE>sh</CODE>. For such programs, the default behaviour of
+Readline is sufficient. This section describes how to use Readline in
+the simplest way possible, perhaps to replace calls in your code to
+<CODE>gets()</CODE> or <CODE>fgets()</CODE>.
+
+
+<A NAME="IDX219"></A>
+<A NAME="IDX220"></A>
+
+
+The function <CODE>readline()</CODE> prints a prompt <VAR>prompt</VAR>
+and then reads and returns a single line of text from the user.
+If <VAR>prompt</VAR> is <CODE>NULL</CODE> or the empty string, no prompt is displayed.
+The line <CODE>readline</CODE> returns is allocated with <CODE>malloc()</CODE>;
+the caller should <CODE>free()</CODE> the line when it has finished with it.
+The declaration for <CODE>readline</CODE> in ANSI C is
+
+
+<TABLE><tr><td>&nbsp;</td><td class=example><pre><CODE>char *readline (const char *<VAR>prompt</VAR>);</CODE>
+</pre></td></tr></table>
+
+So, one might say
+<TABLE><tr><td>&nbsp;</td><td class=example><pre><CODE>char *line = readline ("Enter a line: ");</CODE>
+</pre></td></tr></table>in order to read a line of text from the user.
+The line returned has the final newline removed, so only the
+text remains.
+
+
+If <CODE>readline</CODE> encounters an <CODE>EOF</CODE> while reading the line, and the
+line is empty at that point, then <CODE>(char *)NULL</CODE> is returned.
+Otherwise, the line is ended just as if a newline had been typed.
+
+
+Readline performs some expansion on the <VAR>prompt</VAR> before it is
+displayed on the screen. See the description of <CODE>rl_expand_prompt</CODE>
+(see section <A HREF="readline.html#SEC35">2.4.6 Redisplay</A>) for additional details, especially if <VAR>prompt</VAR>
+will contain characters that do not consume physical screen space when
+displayed.
+
+
+If you want the user to be able to get at the line later, (with
+<KBD>C-p</KBD> for example), you must call <CODE>add_history()</CODE> to save the
+line away in a history list of such lines.
+
+
+<TABLE><tr><td>&nbsp;</td><td class=example><pre><CODE>add_history (line)</CODE>;
+</pre></td></tr></table>
+
+For full details on the GNU History Library, see the associated manual.
+
+
+It is preferable to avoid saving empty lines on the history list, since
+users rarely have a burning need to reuse a blank line. Here is
+a function which usefully replaces the standard <CODE>gets()</CODE> library
+function, and has the advantage of no static buffer to overflow:
+
+
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>/* A static variable for holding the line. */
+static char *line_read = (char *)NULL;
+
+/* Read a string, and return a pointer to it.
+ Returns NULL on EOF. */
+char *
+rl_gets ()
+{
+ /* If the buffer has already been allocated,
+ return the memory to the free pool. */
+ if (line_read)
+ {
+ free (line_read);
+ line_read = (char *)NULL;
+ }
+
+ /* Get a line from the user. */
+ line_read = readline ("");
+
+ /* If the line has any text in it,
+ save it on the history. */
+ if (line_read &#38;&#38; *line_read)
+ add_history (line_read);
+
+ return (line_read);
+}
+</pre></td></tr></table>
+
+This function gives the user the default behaviour of <KBD>TAB</KBD>
+completion: completion on file names. If you do not want Readline to
+complete on filenames, you can change the binding of the <KBD>TAB</KBD> key
+with <CODE>rl_bind_key()</CODE>.
+
+
+<TABLE><tr><td>&nbsp;</td><td class=example><pre><CODE>int rl_bind_key (int <VAR>key</VAR>, rl_command_func_t *<VAR>function</VAR>);</CODE>
+</pre></td></tr></table>
+
+<CODE>rl_bind_key()</CODE> takes two arguments: <VAR>key</VAR> is the character that
+you want to bind, and <VAR>function</VAR> is the address of the function to
+call when <VAR>key</VAR> is pressed. Binding <KBD>TAB</KBD> to <CODE>rl_insert()</CODE>
+makes <KBD>TAB</KBD> insert itself.
+<CODE>rl_bind_key()</CODE> returns non-zero if <VAR>key</VAR> is not a valid
+ASCII character code (between 0 and 255).
+
+
+Thus, to disable the default <KBD>TAB</KBD> behavior, the following suffices:
+<TABLE><tr><td>&nbsp;</td><td class=example><pre><CODE>rl_bind_key ('\t', rl_insert);</CODE>
+</pre></td></tr></table>
+
+This code should be executed once at the start of your program; you
+might write a function called <CODE>initialize_readline()</CODE> which
+performs this and other desired initializations, such as installing
+custom completers (see section <A HREF="readline.html#SEC45">2.6 Custom Completers</A>).

+<H2> 2.2 Custom Functions </H2>
+
+
+
+Readline provides many functions for manipulating the text of
+the line, but it isn't possible to anticipate the needs of all
+programs. This section describes the various functions and variables
+defined within the Readline library which allow a user program to add
+customized functionality to Readline.
+
+
+Before declaring any functions that customize Readline's behavior, or
+using any functionality Readline provides in other code, an
+application writer should include the file <CODE>&#60;readline/readline.h&#62;</CODE>
+in any file that uses Readline's features. Since some of the definitions
+in <CODE>readline.h</CODE> use the <CODE>stdio</CODE> library, the file
+<CODE>&#60;stdio.h&#62;</CODE> should be included before <CODE>readline.h</CODE>.
+
+
+<CODE>readline.h</CODE> defines a C preprocessor variable that should
+be treated as an integer, <CODE>RL_READLINE_VERSION</CODE>, which may
+be used to conditionally compile application code depending on
+the installed Readline version. The value is a hexadecimal
+encoding of the major and minor version numbers of the library,
+of the form 0x<VAR>MMmm</VAR>. <VAR>MM</VAR> is the two-digit major
+version number; <VAR>mm</VAR> is the two-digit minor version number. 
+For Readline 4.2, for example, the value of
+<CODE>RL_READLINE_VERSION</CODE> would be <CODE>0x0402</CODE>.

+<H3> 2.2.1 Readline Typedefs </H3>
+
+
+
+For readability, we declare a number of new object types, all pointers
+to functions.
+
+
+The reason for declaring these new types is to make it easier to write
+code describing pointers to C functions with appropriately prototyped
+arguments and return values.
+
+
+For instance, say we want to declare a variable <VAR>func</VAR> as a pointer
+to a function which takes two <CODE>int</CODE> arguments and returns an
+<CODE>int</CODE> (this is the type of all of the Readline bindable functions).
+Instead of the classic C declaration
+
+
+<CODE>int (*func)();</CODE>
+
+
+or the ANSI-C style declaration
+
+
+<CODE>int (*func)(int, int);</CODE>
+
+
+we may write
+
+
+<CODE>rl_command_func_t *func;</CODE>

+<H3> 2.2.2 Writing a New Function </H3>
+
+
+
+In order to write new functions for Readline, you need to know the
+calling conventions for keyboard-invoked functions, and the names of the
+variables that describe the current state of the line read so far.
+
+
+The calling sequence for a command <CODE>foo</CODE> looks like
+
+
+<TABLE><tr><td>&nbsp;</td><td class=example><pre><CODE>int foo (int count, int key)</CODE>
+</pre></td></tr></table>
+
+where <VAR>count</VAR> is the numeric argument (or 1 if defaulted) and
+<VAR>key</VAR> is the key that invoked this function.
+
+
+It is completely up to the function as to what should be done with the
+numeric argument. Some functions use it as a repeat count, some
+as a flag, and others to choose alternate behavior (refreshing the current
+line as opposed to refreshing the screen, for example). Some choose to
+ignore it. In general, if a
+function uses the numeric argument as a repeat count, it should be able
+to do something useful with both negative and positive arguments.
+At the very least, it should be aware that it can be passed a
+negative argument.
+
+
+A command function should return 0 if its action completes successfully,
+and a value greater than zero if some error occurs.
+This is the convention obeyed by all of the builtin Readline bindable
+command functions.

+<DL>
+<DT>Variable: int rl_already_prompted
+<DD>If an application wishes to display the prompt itself, rather than have
+Readline do it the first time <CODE>readline()</CODE> is called, it should set
+this variable to a non-zero value after displaying the prompt.
+The prompt must also be passed as the argument to <CODE>readline()</CODE> so

+Readline queries for available input when implementing intra-key-sequence
+timeouts during input and incremental searches.
+This may use an application-specific timeout before returning a value;
+Readline uses the value passed to <CODE>rl_set_keyboard_input_timeout()</CODE>
+or the value of the user-settable <VAR>keyseq-timeout</VAR> variable.
+This is designed for use by applications using Readline's callback interface
+(see section <A HREF="readline.html#SEC41">2.4.12 Alternate Interface</A>), which may not use the traditional
+<CODE>read(2)</CODE> and file descriptor interface, or other applications using
+a different input mechanism.
+If an application uses an input mechanism or hook that can potentially exceed
+the value of <VAR>keyseq-timeout</VAR>, it should increase the timeout or set
+this hook appropriately even when not using the callback interface.
+In general, an application that sets <VAR>rl_getc_function</VAR> should consider
+setting <VAR>rl_input_available_hook</VAR> as well.

+<H3> 2.4.1 Naming a Function </H3>
+
+
+
+The user can dynamically change the bindings of keys while using
+Readline. This is done by representing the function with a descriptive
+name. The user is able to type the descriptive name when referring to
+the function. Thus, in an init file, one might find
+
+
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>Meta-Rubout:	backward-kill-word
+</pre></td></tr></table>
+
+This binds the keystroke <KBD>Meta-Rubout</KBD> to the function
+descriptively named <CODE>backward-kill-word</CODE>. You, as the
+programmer, should bind the functions you write to descriptive names as
+well. Readline provides a function for doing that:
+
+
+<A NAME="IDX261"></A>
+<DL>
+<DT>Function: int rl_add_defun (const char *name, rl_command_func_t *function, int key)
+<DD>Add <VAR>name</VAR> to the list of named functions. Make <VAR>function</VAR> be
+the function that gets called. If <VAR>key</VAR> is not -1, then bind it to
+<VAR>function</VAR> using <CODE>rl_bind_key()</CODE>.
+</DL>
+
+
+Using this function alone is sufficient for most applications.
+It is the recommended way to add a few functions to the default
+functions that Readline has built in.
+If you need to do something other than adding a function to Readline,
+you may need to use the underlying functions described below.

+<H3> 2.4.2 Selecting a Keymap </H3>
+
+
+
+Key bindings take place on a keymap. The keymap is the
+association between the keys that the user types and the functions that
+get run. You can make your own keymaps, copy existing keymaps, and tell
+Readline which keymap to use.
+
+
+<A NAME="IDX262"></A>
+<DL>

+<A NAME="IDX264"></A>
+<DL>
+<DT>Function: Keymap rl_make_keymap (void)
+<DD>Return a new keymap with the printing characters bound to rl_insert,
+the lowercase Meta characters bound to run their equivalents, and
+the Meta digits bound to produce numeric arguments.

+<DL>
+<DT>Function: int rl_empty_keymap (Keymap keymap)
+<DD>Return non-zero if there are no keys bound to functions in <VAR>keymap</VAR>;
+zero if there are any keys bound.

+
+
+Readline has several internal keymaps. These functions allow you to
+change which keymap is active.
+
+
+<A NAME="IDX268"></A>
+<DL>
+<DT>Function: Keymap rl_get_keymap (void)

+<DL>
+<DT>Function: Keymap rl_get_keymap_by_name (const char *name)

+be supplied in a <CODE>set keymap</CODE> inputrc line (see section <A HREF="readline.html#SEC9">1.3 Readline Init File</A>).
+</DL>
+
+
+<A NAME="IDX271"></A>
+<DL>
+<DT>Function: char * rl_get_keymap_name (Keymap keymap)

+<A NAME="IDX272"></A>
+<DL>
+<DT>Function: int rl_set_keymap_name (const char *name, Keymap keymap)
+<DD>Set the name of <VAR>keymap</VAR>. This name will then be "registered" and
+available for use in a <CODE>set keymap</CODE> inputrc directive
+see section <A HREF="readline.html#SEC9">1.3 Readline Init File</A>).
+The <VAR>name</VAR> may not be one of Readline's builtin keymap names;
+you may not add a different name for one of Readline's builtin keymaps.
+You may replace the name associated with a given keymap by calling this
+function more than once with the same <VAR>keymap</VAR> argument.
+You may associate a registered <VAR>name</VAR> with a new keymap by calling this
+function more than once with the same <VAR>name</VAR> argument.
+There is no way to remove a named keymap once the name has been
+registered.
+Readline will make a copy of <VAR>name</VAR>.
+The return value is greater than zero unless <VAR>name</VAR> is one of
+Readline's builtin keymap names or <VAR>keymap</VAR> is one of Readline's
+builtin keymaps.

+<H3> 2.4.3 Binding Keys </H3>
+
+
+
+Key sequences are associate with functions through the keymap.
+Readline has several internal keymaps: <CODE>emacs_standard_keymap</CODE>,
+<CODE>emacs_meta_keymap</CODE>, <CODE>emacs_ctlx_keymap</CODE>,
+<CODE>vi_movement_keymap</CODE>, and <CODE>vi_insertion_keymap</CODE>.
+<CODE>emacs_standard_keymap</CODE> is the default, and the examples in
+this manual assume that.
+
+
+Since <CODE>readline()</CODE> installs a set of default key bindings the first
+time it is called, there is always the danger that a custom binding
+installed before the first call to <CODE>readline()</CODE> will be overridden.

+<H3> 2.4.5 Allowing Undoing </H3>
+
+
+
+Supporting the undo command is a painless thing, and makes your
+functions much more useful. It is certainly easy to try
+something if you know you can undo it.
+
+
+If your function simply inserts text once, or deletes text once, and
+uses <CODE>rl_insert_text()</CODE> or <CODE>rl_delete_text()</CODE> to do it, then
+undoing is already done for you automatically.
+
+
+If you do multiple insertions or multiple deletions, or any combination
+of these operations, you should group them together into one operation.
+This is done with <CODE>rl_begin_undo_group()</CODE> and
+<CODE>rl_end_undo_group()</CODE>.
+
+
+The types of events that can be undone are:
+
+
+<TABLE><tr><td>&nbsp;</td><td class=smallexample><pre>enum undo_code { UNDO_DELETE, UNDO_INSERT, UNDO_BEGIN, UNDO_END }; 
+</pre></td></tr></table>
+
+Notice that <CODE>UNDO_DELETE</CODE> means to insert some text, and
+<CODE>UNDO_INSERT</CODE> means to delete some text. That is, the undo code
+tells what to undo, not how to undo it. <CODE>UNDO_BEGIN</CODE> and
+<CODE>UNDO_END</CODE> are tags added by <CODE>rl_begin_undo_group()</CODE> and
+<CODE>rl_end_undo_group()</CODE>.
+
+
+<A NAME="IDX298"></A>
+<DL>
+<DT>Function: int rl_begin_undo_group (void)
+<DD>Begins saving undo information in a group construct. The undo
+information usually comes from calls to <CODE>rl_insert_text()</CODE> and
+<CODE>rl_delete_text()</CODE>, but could be the result of calls to
+<CODE>rl_add_undo()</CODE>.
+</DL>
+
+
+<A NAME="IDX299"></A>
+<DL>
+<DT>Function: int rl_end_undo_group (void)
+<DD>Closes the current undo group started with <CODE>rl_begin_undo_group
+()</CODE>. There should be one call to <CODE>rl_end_undo_group()</CODE>
+for each call to <CODE>rl_begin_undo_group()</CODE>.
+</DL>
+
+
+<A NAME="IDX300"></A>
+<DL>
+<DT>Function: void rl_add_undo (enum undo_code what, int start, int end, char *text)
+<DD>Remember how to undo an event (according to <VAR>what</VAR>). The affected
+text runs from <VAR>start</VAR> to <VAR>end</VAR>, and encompasses <VAR>text</VAR>.
+</DL>
+
+
+<A NAME="IDX301"></A>
+<DL>
+<DT>Function: void rl_free_undo_list (void)
+<DD>Free the existing undo list.
+</DL>
+
+
+<A NAME="IDX302"></A>
+<DL>
+<DT>Function: int rl_do_undo (void)
+<DD>Undo the first thing on the undo list. Returns <CODE>0</CODE> if there was
+nothing to undo, non-zero if something was undone.
+</DL>
+
+
+Finally, if you neither insert nor delete text, but directly modify the
+existing text (e.g., change its case), call <CODE>rl_modifying()</CODE>
+once, just before you modify the text. You must supply the indices of
+the text range that you are going to modify.
+
+
+<A NAME="IDX303"></A>
+<DL>
+<DT>Function: int rl_modifying (int start, int end)
+<DD>Tell Readline to save the text between <VAR>start</VAR> and <VAR>end</VAR> as a
+single undo unit. It is assumed that you will subsequently modify
+that text.

+<H3> 2.4.12 Alternate Interface </H3>
+
+
+
+An alternate interface is available to plain <CODE>readline()</CODE>. Some
+applications need to interleave keyboard I/O with file, device, or
+window system I/O, typically by using a main loop to <CODE>select()</CODE>
+on various file descriptors. To accommodate this need, readline can
+also be invoked as a `callback' function from an event loop. There
+are functions available to make this easy.
+
+
+<A NAME="IDX362"></A>
+<DL>
+<DT>Function: void rl_callback_handler_install (const char *prompt, rl_vcpfunc_t *lhandler)
+<DD>Set up the terminal for readline I/O and display the initial
+expanded value of <VAR>prompt</VAR>. Save the value of <VAR>lhandler</VAR> to
+use as a handler function to call when a complete line of input has been
+entered.
+The handler function receives the text of the line as an argument.
+As with <CODE>readline()</CODE>, the handler function should <CODE>free</CODE> the
+line when it it finished with it.
+</DL>
+
+
+<A NAME="IDX363"></A>
+<DL>
+<DT>Function: void rl_callback_read_char (void)
+<DD>Whenever an application determines that keyboard input is available, it
+should call <CODE>rl_callback_read_char()</CODE>, which will read the next
+character from the current input source.
+If that character completes the line, <CODE>rl_callback_read_char</CODE> will
+invoke the <VAR>lhandler</VAR> function installed by
+<CODE>rl_callback_handler_install</CODE> to process the line.
+Before calling the <VAR>lhandler</VAR> function, the terminal settings are
+reset to the values they had before calling
+<CODE>rl_callback_handler_install</CODE>.
+If the <VAR>lhandler</VAR> function returns,
+and the line handler remains installed,
+the terminal settings are modified for Readline's use again.
+<CODE>EOF</CODE> is indicated by calling <VAR>lhandler</VAR> with a
+<CODE>NULL</CODE> line.
+</DL>
+
+
+<A NAME="IDX364"></A>
+<DL>
+<DT>Function: void rl_callback_sigcleanup (void)
+<DD>Clean up any internal state the callback interface uses to maintain state
+between calls to rl_callback_read_char (e.g., the state of any active
+incremental searches). This is intended to be used by applications that
+wish to perform their own signal handling; Readline's internal signal handler
+calls this when appropriate.
+</DL>
+
+
+<A NAME="IDX365"></A>
+<DL>
+<DT>Function: void rl_callback_handler_remove (void)
+<DD>Restore the terminal to its initial state and remove the line handler.
+You may call this function from within a callback as well as independently.
+If the <VAR>lhandler</VAR> installed by <CODE>rl_callback_handler_install</CODE>
+does not exit the program, either this function or the function referred
+to by the value of <CODE>rl_deprep_term_function</CODE> should be called before
+the program exits to reset the terminal settings.

+<H2> 2.5 Readline Signal Handling </H2>
+
+
+
+Signals are asynchronous events sent to a process by the Unix kernel,
+sometimes on behalf of another process. They are intended to indicate
+exceptional events, like a user pressing the interrupt key on his terminal,
+or a network connection being broken. There is a class of signals that can
+be sent to the process currently reading input from the keyboard. Since
+Readline changes the terminal attributes when it is called, it needs to
+perform special processing when such a signal is received in order to
+restore the terminal to a sane state, or provide application writers with
+functions to do so manually. 
+
+
+Readline contains an internal signal handler that is installed for a
+number of signals (<CODE>SIGINT</CODE>, <CODE>SIGQUIT</CODE>, <CODE>SIGTERM</CODE>,
+<CODE>SIGHUP</CODE>, 
+<CODE>SIGALRM</CODE>, <CODE>SIGTSTP</CODE>, <CODE>SIGTTIN</CODE>, and <CODE>SIGTTOU</CODE>).
+When one of these signals is received, the signal handler
+will reset the terminal attributes to those that were in effect before
+<CODE>readline()</CODE> was called, reset the signal handling to what it was
+before <CODE>readline()</CODE> was called, and resend the signal to the calling
+application.
+If and when the calling application's signal handler returns, Readline
+will reinitialize the terminal and continue to accept input.
+When a <CODE>SIGINT</CODE> is received, the Readline signal handler performs
+some additional work, which will cause any partially-entered line to be
+aborted (see the description of <CODE>rl_free_line_state()</CODE> below).
+
+
+There is an additional Readline signal handler, for <CODE>SIGWINCH</CODE>, which
+the kernel sends to a process whenever the terminal's size changes (for
+example, if a user resizes an <CODE>xterm</CODE>). The Readline <CODE>SIGWINCH</CODE>
+handler updates Readline's internal screen size information, and then calls
+any <CODE>SIGWINCH</CODE> signal handler the calling application has installed. 
+Readline calls the application's <CODE>SIGWINCH</CODE> signal handler without
+resetting the terminal to its original state. If the application's signal
+handler does more than update its idea of the terminal size and return (for
+example, a <CODE>longjmp</CODE> back to a main processing loop), it must
+call <CODE>rl_cleanup_after_signal()</CODE> (described below), to restore the
+terminal state.
+
+
+When an application is using the callback interface
+(see section <A HREF="readline.html#SEC41">2.4.12 Alternate Interface</A>), Readline installs signal handlers only for
+the duration of the call to <CODE>rl_callback_read_char</CODE>. Applications
+using the callback interface should be prepared to clean up Readline's
+state if they wish to handle the signal before the line handler completes
+and restores the terminal state.
+
+
+If an application using the callback interface wishes to have Readline
+install its signal handlers at the time the application calls
+<CODE>rl_callback_handler_install</CODE> and remove them only when a complete
+line of input has been read, it should set the
+<CODE>rl_persistent_signal_handlers</CODE> variable to a non-zero value.
+This allows an application to defer all of the handling of the signals
+Readline catches to Readline.
+Applications should use this variable with care; it can result in Readline
+catching signals and not acting on them (or allowing the application to react
+to them) until the application calls <CODE>rl_callback_read_char</CODE>. This
+can result in an application becoming less responsive to keyboard signals
+like SIGINT.
+If an application does not want or need to perform any signal handling, or
+does not need to do any processing between calls to <CODE>rl_callback_read_char</CODE>,
+setting this variable may be desirable.
+
+
+Readline provides two variables that allow application writers to
+control whether or not it will catch certain signals and act on them
+when they are received. It is important that applications change the
+values of these variables only when calling <CODE>readline()</CODE>, not in
+a signal handler, so Readline's internal signal state is not corrupted.

+<H3> 2.6.1 How Completing Works </H3>
+
+
+
+In order to complete some text, the full list of possible completions
+must be available. That is, it is not possible to accurately
+expand a partial word without knowing all of the possible words
+which make sense in that context. The Readline library provides
+the user interface to completion, and two of the most common
+completion functions: filename and username. For completing other types
+of text, you must write your own completion function. This section
+describes exactly what such functions must do, and provides an example.
+
+
+There are three major functions used to perform completion:
+
+
+<OL>
+<LI>
+The user-interface function <CODE>rl_complete()</CODE>. This function is
+called with the same arguments as other bindable Readline functions:
+<VAR>count</VAR> and <VAR>invoking_key</VAR>.
+It isolates the word to be completed and calls
+<CODE>rl_completion_matches()</CODE> to generate a list of possible completions.
+It then either lists the possible completions, inserts the possible
+completions, or actually performs the
+completion, depending on which behavior is desired.
+
+
+<LI>
+The internal function <CODE>rl_completion_matches()</CODE> uses an
+application-supplied generator function to generate the list of
+possible matches, and then returns the array of these matches.
+The caller should place the address of its generator function in
+<CODE>rl_completion_entry_function</CODE>.
+
+
+<LI>
+The generator function is called repeatedly from
+<CODE>rl_completion_matches()</CODE>, returning a string each time. The
+arguments to the generator function are <VAR>text</VAR> and <VAR>state</VAR>.
+<VAR>text</VAR> is the partial word to be completed. <VAR>state</VAR> is zero the
+first time the function is called, allowing the generator to perform
+any necessary initialization, and a positive non-zero integer for
+each subsequent call. The generator function returns
+<CODE>(char *)NULL</CODE> to inform <CODE>rl_completion_matches()</CODE> that there are
+no more possibilities left. Usually the generator function computes the
+list of possible completions when <VAR>state</VAR> is zero, and returns them
+one at a time on subsequent calls. Each string the generator function
+returns as a match must be allocated with <CODE>malloc()</CODE>; Readline
+frees the strings when it has finished with them.
+Such a generator function is referred to as an
+application-specific completion function.

+<DD>Complete the word at or before point. You have supplied the function
+that does the initial simple matching selection algorithm (see
+<CODE>rl_completion_matches()</CODE> and <CODE>rl_completion_entry_function</CODE>).
+The default is to do filename
+completion. This calls <CODE>rl_complete_internal()</CODE> with an

+
+
+
+<A NAME="IDX392"></A>
+<DL>
+<DT>Variable: rl_compentry_func_t * rl_completion_entry_function
+<DD>A pointer to the generator function for <CODE>rl_completion_matches()</CODE>.
+<CODE>NULL</CODE> means to use <CODE>rl_filename_completion_function()</CODE>,
+the default filename completer.
+</DL>
+
+
+<A NAME="IDX393"></A>
+<DL>
+<DT>Variable: rl_completion_func_t * rl_attempted_completion_function
+<DD>A pointer to an alternative function to create matches.
+The function is called with <VAR>text</VAR>, <VAR>start</VAR>, and <VAR>end</VAR>.
+<VAR>start</VAR> and <VAR>end</VAR> are indices in <CODE>rl_line_buffer</CODE> defining
+the boundaries of <VAR>text</VAR>, which is a character string.
+If this function exists and returns <CODE>NULL</CODE>, or if this variable is
+set to <CODE>NULL</CODE>, then <CODE>rl_complete()</CODE> will call the value of
+<CODE>rl_completion_entry_function</CODE> to generate matches, otherwise the
+array of strings returned will be used.
+If this function sets the <CODE>rl_attempted_completion_over</CODE>
+variable to a non-zero value, Readline will not perform its default
+completion even if this function returns no matches.
+</DL>
+
+
+<A NAME="IDX394"></A>
+<DL>
+<DT>Variable: rl_quote_func_t * rl_filename_quoting_function
+<DD>A pointer to a function that will quote a filename in an
+application-specific fashion. This is called if filename completion is being
+attempted and one of the characters in <CODE>rl_filename_quote_characters</CODE>
+appears in a completed filename. The function is called with
+<VAR>text</VAR>, <VAR>match_type</VAR>, and <VAR>quote_pointer</VAR>. The <VAR>text</VAR>
+is the filename to be quoted. The <VAR>match_type</VAR> is either
+<CODE>SINGLE_MATCH</CODE>, if there is only one completion match, or
+<CODE>MULT_MATCH</CODE>. Some functions use this to decide whether or not to
+insert a closing quote character. The <VAR>quote_pointer</VAR> is a pointer
+to any opening quote character the user typed. Some functions choose
+to reset this character.
+</DL>
+
+
+<A NAME="IDX395"></A>
+<DL>
+<DT>Variable: rl_dequote_func_t * rl_filename_dequoting_function
+<DD>A pointer to a function that will remove application-specific quoting
+characters from a filename before completion is attempted, so those
+characters do not interfere with matching the text against names in
+the filesystem. It is called with <VAR>text</VAR>, the text of the word
+to be dequoted, and <VAR>quote_char</VAR>, which is the quoting character 
+that delimits the filename (usually <SAMP>`''</SAMP> or <SAMP>`"'</SAMP>). If
+<VAR>quote_char</VAR> is zero, the filename was not in an embedded string.
+</DL>
+
+
+<A NAME="IDX396"></A>
+<DL>
+<DT>Variable: rl_linebuf_func_t * rl_char_is_quoted_p
+<DD>A pointer to a function to call that determines whether or not a specific
+character in the line buffer is quoted, according to whatever quoting
+mechanism the program calling Readline uses. The function is called with
+two arguments: <VAR>text</VAR>, the text of the line, and <VAR>index</VAR>, the
+index of the character in the line. It is used to decide whether a
+character found in <CODE>rl_completer_word_break_characters</CODE> should be
+used to break words for the completer.
+</DL>
+
+
+<A NAME="IDX397"></A>
+<DL>
+<DT>Variable: rl_compignore_func_t * rl_ignore_some_completions_function
+<DD>This function, if defined, is called by the completer when real filename
+completion is done, after all the matching names have been generated.
+It is passed a <CODE>NULL</CODE> terminated array of matches.
+The first element (<CODE>matches0</CODE>) is the
+maximal substring common to all matches. This function can
+re-arrange the list of matches as required, but each element deleted
+from the array must be freed.
+</DL>
+
+
+<A NAME="IDX398"></A>
+<DL>
+<DT>Variable: rl_icppfunc_t * rl_directory_completion_hook
+<DD>This function, if defined, is allowed to modify the directory portion
+of filenames Readline completes.
+It could be used to expand symbolic links or shell variables in pathnames.
+It is called with the address of a string (the current directory name) as an
+argument, and may modify that string.
+If the string is replaced with a new string, the old value should be freed.
+Any modified directory name should have a trailing slash.
+The modified value will be used as part of the completion, replacing
+the directory portion of the pathname the user typed.
+At the least, even if no other expansion is performed, this function should
+remove any quote characters from the directory name, because its result will
+be passed directly to <CODE>opendir()</CODE>.
+
+
+The directory completion hook returns an integer that should be non-zero if
+the function modifies its directory argument.
+The function should not modify the directory argument if it returns 0.
+</DL>
+
+
+<A NAME="IDX399"></A>
+<DL>
+<DT>Variable: rl_icppfunc_t * rl_directory_rewrite_hook;
+<DD>If non-zero, this is the address of a function to call when completing
+a directory name. This function takes the address of the directory name
+to be modified as an argument. Unlike <CODE>rl_directory_completion_hook</CODE>,
+it only modifies the directory name used in <CODE>opendir</CODE>, not what is
+displayed when the possible completions are printed or inserted. It is
+called before rl_directory_completion_hook.
+At the least, even if no other expansion is performed, this function should
+remove any quote characters from the directory name, because its result will
+be passed directly to <CODE>opendir()</CODE>.
+
+
+The directory rewrite hook returns an integer that should be non-zero if
+the function modifies its directory argument.
+The function should not modify the directory argument if it returns 0.
+</DL>
+
+
+<A NAME="IDX400"></A>
+<DL>
+<DT>Variable: rl_icppfunc_t * rl_filename_stat_hook
+<DD>If non-zero, this is the address of a function for the completer to
+call before deciding which character to append to a completed name.
+This function modifies its filename name argument, and the modified value
+is passed to <CODE>stat()</CODE> to determine the file's type and characteristics.
+This function does not need to remove quote characters from the filename.
+
+
+The stat hook returns an integer that should be non-zero if
+the function modifies its directory argument.
+The function should not modify the directory argument if it returns 0.
+</DL>
+
+
+<A NAME="IDX401"></A>
+<DL>
+<DT>Variable: rl_dequote_func_t * rl_filename_rewrite_hook
+<DD>If non-zero, this is the address of a function called when reading
+directory entries from the filesystem for completion and comparing
+them to the partial word to be completed. The function should
+perform any necessary application or system-specific conversion on
+the filename, such as converting between character sets or converting
+from a filesystem format to a character input format.
+The function takes two arguments: <VAR>fname</VAR>, the filename to be converted,
+and <VAR>fnlen</VAR>, its length in bytes.
+It must either return its first argument (if no conversion takes place)
+or the converted filename in newly-allocated memory. The converted
+form is used to compare against the word to be completed, and, if it
+matches, is added to the list of matches. Readline will free the
+allocated string.
+</DL>
+
+
+<A NAME="IDX402"></A>
+<DL>
+<DT>Variable: rl_compdisp_func_t * rl_completion_display_matches_hook
+<DD>If non-zero, then this is the address of a function to call when
+completing a word would normally display the list of possible matches.
+This function is called in lieu of Readline displaying the list.
+It takes three arguments:
+(<CODE>char **</CODE><VAR>matches</VAR>, <CODE>int</CODE> <VAR>num_matches</VAR>, <CODE>int</CODE> <VAR>max_length</VAR>)
+where <VAR>matches</VAR> is the array of matching strings,
+<VAR>num_matches</VAR> is the number of strings in that array, and
+<VAR>max_length</VAR> is the length of the longest string in that array.
+Readline provides a convenience function, <CODE>rl_display_match_list</CODE>,
+that takes care of doing the display to Readline's output stream.
+You may call that function from this hook.
+</DL>
+
+
+<A NAME="IDX403"></A>
+<DL>
+<DT>Variable: const char * rl_basic_word_break_characters
+<DD>The basic list of characters that signal a break between words for the
+completer routine. The default value of this variable is the characters
+which break words for completion in Bash:
+<CODE>" \t\n\"\\'`@$>&#60;=;|&#38;{("</CODE>.
+</DL>
+
+
+<A NAME="IDX404"></A>
+<DL>
+<DT>Variable: const char * rl_basic_quote_characters
+<DD>A list of quote characters which can cause a word break.
+</DL>
+
+
+<A NAME="IDX405"></A>
+<DL>
+<DT>Variable: const char * rl_completer_word_break_characters
+<DD>The list of characters that signal a break between words for
+<CODE>rl_complete_internal()</CODE>. The default list is the value of
+<CODE>rl_basic_word_break_characters</CODE>.
+</DL>
+
+
+<A NAME="IDX406"></A>
+<DL>
+<DT>Variable: rl_cpvfunc_t * rl_completion_word_break_hook
+<DD>If non-zero, this is the address of a function to call when Readline is
+deciding where to separate words for word completion. It should return
+a character string like <CODE>rl_completer_word_break_characters</CODE> to be
+used to perform the current completion. The function may choose to set
+<CODE>rl_completer_word_break_characters</CODE> itself. If the function
+returns <CODE>NULL</CODE>, <CODE>rl_completer_word_break_characters</CODE> is used.
+</DL>
+
+
+<A NAME="IDX407"></A>
+<DL>
+<DT>Variable: const char * rl_completer_quote_characters
+<DD>A list of characters which can be used to quote a substring of the line.
+Completion occurs on the entire substring, and within the substring
+<CODE>rl_completer_word_break_characters</CODE> are treated as any other character,
+unless they also appear within this list.
+</DL>
+
+
+<A NAME="IDX408"></A>
+<DL>
+<DT>Variable: const char * rl_filename_quote_characters
+<DD>A list of characters that cause a filename to be quoted by the completer
+when they appear in a completed filename. The default is the null string.
+</DL>
+
+
+<A NAME="IDX409"></A>
+<DL>
+<DT>Variable: const char * rl_special_prefixes
+<DD>The list of characters that are word break characters, but should be
+left in <VAR>text</VAR> when it is passed to the completion function.
+Programs can use this to help determine what kind of completing to do.
+For instance, Bash sets this variable to "$@" so that it can complete
+shell variables and hostnames.
+</DL>
+
+
+<A NAME="IDX410"></A>
+<DL>
+<DT>Variable: int rl_completion_query_items
+<DD>Up to this many items will be displayed in response to a
+possible-completions call. After that, readline asks the user if she is sure
+she wants to see them all. The default value is 100. A negative value 
+indicates that Readline should never ask the user.
+</DL>
+
+
+<A NAME="IDX411"></A>
+<DL>
+<DT>Variable: int rl_completion_append_character
+<DD>When a single completion alternative matches at the end of the command
+line, this character is appended to the inserted completion text. The
+default is a space character (<SAMP>` '</SAMP>). Setting this to the null
+character (<SAMP>`\0'</SAMP>) prevents anything being appended automatically.
+This can be changed in application-specific completion functions to
+provide the "most sensible word separator character" according to
+an application-specific command line syntax specification.
+It is set to the default before any application-specific completion function
+is called, and may only be changed within such a function.
+</DL>
+
+
+<A NAME="IDX412"></A>
+<DL>
+<DT>Variable: int rl_completion_suppress_append
+<DD>If non-zero, <VAR>rl_completion_append_character</VAR> is not appended to
+matches at the end of the command line, as described above.
+It is set to 0 before any application-specific completion function
+is called, and may only be changed within such a function.
+</DL>
+
+
+<A NAME="IDX413"></A>
+<DL>
+<DT>Variable: int rl_completion_quote_character
+<DD>When Readline is completing quoted text, as delimited by one of the
+characters in <VAR>rl_completer_quote_characters</VAR>, it sets this variable
+to the quoting character found.
+This is set before any application-specific completion function is called.
+</DL>
+
+
+<A NAME="IDX414"></A>
+<DL>
+<DT>Variable: int rl_completion_suppress_quote
+<DD>If non-zero, Readline does not append a matching quote character when
+performing completion on a quoted string.
+It is set to 0 before any application-specific completion function
+is called, and may only be changed within such a function.
+</DL>
+
+
+<A NAME="IDX415"></A>
+<DL>
+<DT>Variable: int rl_completion_found_quote
+<DD>When Readline is completing quoted text, it sets this variable
+to a non-zero value if the word being completed contains or is delimited
+by any quoting characters, including backslashes.
+This is set before any application-specific completion function is called.
+</DL>
+
+
+<A NAME="IDX416"></A>
+<DL>
+<DT>Variable: int rl_completion_mark_symlink_dirs
+<DD>If non-zero, a slash will be appended to completed filenames that are
+symbolic links to directory names, subject to the value of the
+user-settable <VAR>mark-directories</VAR> variable.
+This variable exists so that application-specific completion functions
+can override the user's global preference (set via the
+<VAR>mark-symlinked-directories</VAR> Readline variable) if appropriate.
+This variable is set to the user's preference before any
+application-specific completion function is called, so unless that
+function modifies the value, the user's preferences are honored.
+</DL>
+
+
+<A NAME="IDX417"></A>
+<DL>
+<DT>Variable: int rl_ignore_completion_duplicates
+<DD>If non-zero, then duplicates in the matches are removed.
+The default is 1.
+</DL>
+
+
+<A NAME="IDX418"></A>
+<DL>
+<DT>Variable: int rl_filename_completion_desired
+<DD>Non-zero means that the results of the matches are to be treated as
+filenames. This is always zero when completion is attempted,
+and can only be changed
+within an application-specific completion function. If it is set to a
+non-zero value by such a function, directory names have a slash appended
+and Readline attempts to quote completed filenames if they contain any
+characters in <CODE>rl_filename_quote_characters</CODE> and
+<CODE>rl_filename_quoting_desired</CODE> is set to a non-zero value.
+</DL>
+
+
+<A NAME="IDX419"></A>
+<DL>
+<DT>Variable: int rl_filename_quoting_desired
+<DD>Non-zero means that the results of the matches are to be quoted using
+double quotes (or an application-specific quoting mechanism) if the
+completed filename contains any characters in
+<CODE>rl_filename_quote_chars</CODE>. This is always non-zero
+when completion is attempted, and can only be changed within an
+application-specific completion function.
+The quoting is effected via a call to the function pointed to
+by <CODE>rl_filename_quoting_function</CODE>.
+</DL>
+
+
+<A NAME="IDX420"></A>
+<DL>
+<DT>Variable: int rl_attempted_completion_over
+<DD>If an application-specific completion function assigned to
+<CODE>rl_attempted_completion_function</CODE> sets this variable to a non-zero
+value, Readline will not perform its default filename completion even
+if the application's completion function returns no matches.
+It should be set only by an application's completion function.
+</DL>
+
+
+<A NAME="IDX421"></A>
+<DL>
+<DT>Variable: int rl_sort_completion_matches
+<DD>If an application sets this variable to 0, Readline will not sort the
+list of completions (which implies that it cannot remove any duplicate
+completions). The default value is 1, which means that Readline will
+sort the completions and, depending on the value of
+<CODE>rl_ignore_completion_duplicates</CODE>, will attempt to remove duplicate
+matches.
+</DL>
+
+
+<A NAME="IDX422"></A>
+<DL>

+PREAMBLE
+
+
+The purpose of this License is to make a manual, textbook, or other
+functional and useful document free in the sense of freedom: to
+assure everyone the effective freedom to copy and redistribute it,
+with or without modifying it, either commercially or noncommercially.
+Secondarily, this License preserves for the author and publisher a way
+to get credit for their work, while not being considered responsible
+for modifications made by others.
+
+
+This License is a kind of "copyleft", which means that derivative
+works of the document must themselves be free in the same sense. It
+complements the GNU General Public License, which is a copyleft
+license designed for free software.
+
+
+We have designed this License in order to use it for manuals for free
+software, because free software needs free documentation: a free
+program should come with manuals providing the same freedoms that the
+software does. But this License is not limited to software manuals;
+it can be used for any textual work, regardless of subject matter or
+whether it is published as a printed book. We recommend this License
+principally for works whose purpose is instruction or reference.
+
+
+<LI>
+APPLICABILITY AND DEFINITIONS
+
+
+This License applies to any manual or other work, in any medium, that
+contains a notice placed by the copyright holder saying it can be
+distributed under the terms of this License. Such a notice grants a
+world-wide, royalty-free license, unlimited in duration, to use that
+work under the conditions stated herein. The "Document", below,
+refers to any such manual or work. Any member of the public is a
+licensee, and is addressed as "you". You accept the license if you
+copy, modify or distribute the work in a way requiring permission
+under copyright law.
+
+
+A "Modified Version" of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with
+modifications and/or translated into another language.
+
+
+A "Secondary Section" is a named appendix or a front-matter section
+of the Document that deals exclusively with the relationship of the
+publishers or authors of the Document to the Document's overall
+subject (or to related matters) and contains nothing that could fall
+directly within that overall subject. (Thus, if the Document is in
+part a textbook of mathematics, a Secondary Section may not explain
+any mathematics.) The relationship could be a matter of historical
+connection with the subject or with related matters, or of legal,
+commercial, philosophical, ethical or political position regarding
+them.
+
+
+The "Invariant Sections" are certain Secondary Sections whose titles
+are designated, as being those of Invariant Sections, in the notice
+that says that the Document is released under this License. If a
+section does not fit the above definition of Secondary then it is not
+allowed to be designated as Invariant. The Document may contain zero
+Invariant Sections. If the Document does not identify any Invariant
+Sections then there are none.
+
+
+The "Cover Texts" are certain short passages of text that are listed,
+as Front-Cover Texts or Back-Cover Texts, in the notice that says that
+the Document is released under this License. A Front-Cover Text may
+be at most 5 words, and a Back-Cover Text may be at most 25 words.
+
+
+A "Transparent" copy of the Document means a machine-readable copy,
+represented in a format whose specification is available to the
+general public, that is suitable for revising the document
+straightforwardly with generic text editors or (for images composed of
+pixels) generic paint programs or (for drawings) some widely available
+drawing editor, and that is suitable for input to text formatters or
+for automatic translation to a variety of formats suitable for input
+to text formatters. A copy made in an otherwise Transparent file
+format whose markup, or absence of markup, has been arranged to thwart
+or discourage subsequent modification by readers is not Transparent.
+An image format is not Transparent if used for any substantial amount
+of text. A copy that is not "Transparent" is called "Opaque".
+
+
+Examples of suitable formats for Transparent copies include plain
+ASCII without markup, Texinfo input format, LaTeX input
+format, SGML or XML using a publicly available
+DTD, and standard-conforming simple HTML,
+PostScript or PDF designed for human modification. Examples
+of transparent image formats include PNG, XCF and
+JPG. Opaque formats include proprietary formats that can be
+read and edited only by proprietary word processors, SGML or
+XML for which the DTD and/or processing tools are
+not generally available, and the machine-generated HTML,
+PostScript or PDF produced by some word processors for
+output purposes only.
+
+
+The "Title Page" means, for a printed book, the title page itself,
+plus such following pages as are needed to hold, legibly, the material
+this License requires to appear in the title page. For works in
+formats which do not have any title page as such, "Title Page" means
+the text near the most prominent appearance of the work's title,
+preceding the beginning of the body of the text.
+
+
+The "publisher" means any person or entity that distributes copies
+of the Document to the public.
+
+
+A section "Entitled XYZ" means a named subunit of the Document whose
+title either is precisely XYZ or contains XYZ in parentheses following
+text that translates XYZ in another language. (Here XYZ stands for a
+specific section name mentioned below, such as "Acknowledgements",
+"Dedications", "Endorsements", or "History".) To "Preserve the Title"
+of such a section when you modify the Document means that it remains a
+section "Entitled XYZ" according to this definition.
+
+
+The Document may include Warranty Disclaimers next to the notice which
+states that this License applies to the Document. These Warranty
+Disclaimers are considered to be included by reference in this
+License, but only as regards disclaiming warranties: any other
+implication that these Warranty Disclaimers may have is void and has
+no effect on the meaning of this License.
+
+
+<LI>
+VERBATIM COPYING
+
+
+You may copy and distribute the Document in any medium, either
+commercially or noncommercially, provided that this License, the
+copyright notices, and the license notice saying this License applies
+to the Document are reproduced in all copies, and that you add no other
+conditions whatsoever to those of this License. You may not use
+technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute. However, you may accept
+compensation in exchange for copies. If you distribute a large enough
+number of copies you must also follow the conditions in section 3.
+
+
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+
+
+<LI>
+COPYING IN QUANTITY
+
+
+If you publish printed copies (or copies in media that commonly have
+printed covers) of the Document, numbering more than 100, and the
+Document's license notice requires Cover Texts, you must enclose the
+copies in covers that carry, clearly and legibly, all these Cover
+Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
+the back cover. Both covers must also clearly and legibly identify
+you as the publisher of these copies. The front cover must present
+the full title with all words of the title equally prominent and
+visible. You may add other material on the covers in addition.
+Copying with changes limited to the covers, as long as they preserve
+the title of the Document and satisfy these conditions, can be treated
+as verbatim copying in other respects.
+
+
+If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+
+
+If you publish or distribute Opaque copies of the Document numbering
+more than 100, you must either include a machine-readable Transparent
+copy along with each Opaque copy, or state in or with each Opaque copy
+a computer-network location from which the general network-using
+public has access to download using public-standard network protocols
+a complete Transparent copy of the Document, free of added material.
+If you use the latter option, you must take reasonably prudent steps,
+when you begin distribution of Opaque copies in quantity, to ensure
+that this Transparent copy will remain thus accessible at the stated
+location until at least one year after the last time you distribute an
+Opaque copy (directly or through your agents or retailers) of that
+edition to the public.
+
+
+It is requested, but not required, that you contact the authors of the
+Document well before redistributing any large number of copies, to give
+them a chance to provide you with an updated version of the Document.
+
+
+<LI>
+MODIFICATIONS
+
+
+You may copy and distribute a Modified Version of the Document under
+the conditions of sections 2 and 3 above, provided that you release
+the Modified Version under precisely this License, with the Modified
+Version filling the role of the Document, thus licensing distribution
+and modification of the Modified Version to whoever possesses a copy
+of it. In addition, you must do these things in the Modified Version:
+
+
+<OL>
+<LI>
+Use in the Title Page (and on the covers, if any) a title distinct
+from that of the Document, and from those of previous versions
+(which should, if there were any, be listed in the History section
+of the Document). You may use the same title as a previous version
+if the original publisher of that version gives permission.
+
+
+<LI>
+List on the Title Page, as authors, one or more persons or entities
+responsible for authorship of the modifications in the Modified
+Version, together with at least five of the principal authors of the
+Document (all of its principal authors, if it has fewer than five),
+unless they release you from this requirement.
+
+
+<LI>
+State on the Title page the name of the publisher of the
+Modified Version, as the publisher.
+
+
+<LI>
+Preserve all the copyright notices of the Document.
+
+
+<LI>
+Add an appropriate copyright notice for your modifications
+adjacent to the other copyright notices.
+
+
+<LI>
+Include, immediately after the copyright notices, a license notice
+giving the public permission to use the Modified Version under the
+terms of this License, in the form shown in the Addendum below.
+
+
+<LI>
+Preserve in that license notice the full lists of Invariant Sections
+and required Cover Texts given in the Document's license notice.
+
+
+<LI>
+Include an unaltered copy of this License.
+
+
+<LI>
+Preserve the section Entitled "History", Preserve its Title, and add
+to it an item stating at least the title, year, new authors, and
+publisher of the Modified Version as given on the Title Page. If
+there is no section Entitled "History" in the Document, create one
+stating the title, year, authors, and publisher of the Document as
+given on its Title Page, then add an item describing the Modified
+Version as stated in the previous sentence.
+
+
+<LI>
+Preserve the network location, if any, given in the Document for
+public access to a Transparent copy of the Document, and likewise
+the network locations given in the Document for previous versions
+it was based on. These may be placed in the "History" section.
+You may omit a network location for a work that was published at
+least four years before the Document itself, or if the original
+publisher of the version it refers to gives permission.
+
+
+<LI>
+For any section Entitled "Acknowledgements" or "Dedications", Preserve
+the Title of the section, and preserve in the section all the
+substance and tone of each of the contributor acknowledgements and/or
+dedications given therein.
+
+
+<LI>
+Preserve all the Invariant Sections of the Document,
+unaltered in their text and in their titles. Section numbers
+or the equivalent are not considered part of the section titles.
+
+
+<LI>
+Delete any section Entitled "Endorsements". Such a section
+may not be included in the Modified Version.
+
+
+<LI>
+Do not retitle any existing section to be Entitled "Endorsements" or
+to conflict in title with any Invariant Section.
+
+
+<LI>
+Preserve any Warranty Disclaimers.
+</OL>
+
+
+If the Modified Version includes new front-matter sections or
+appendices that qualify as Secondary Sections and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant. To do this, add their titles to the
+list of Invariant Sections in the Modified Version's license notice.
+These titles must be distinct from any other section titles.
+
+
+You may add a section Entitled "Endorsements", provided it contains
+nothing but endorsements of your Modified Version by various
+parties--for example, statements of peer review or that the text has
+been approved by an organization as the authoritative definition of a
+standard.
+
+
+You may add a passage of up to five words as a Front-Cover Text, and a
+passage of up to 25 words as a Back-Cover Text, to the end of the list
+of Cover Texts in the Modified Version. Only one passage of
+Front-Cover Text and one of Back-Cover Text may be added by (or
+through arrangements made by) any one entity. If the Document already
+includes a cover text for the same cover, previously added by you or
+by arrangement made by the same entity you are acting on behalf of,
+you may not add another; but you may replace the old one, on explicit
+permission from the previous publisher that added the old one.
+
+
+The author(s) and publisher(s) of the Document do not by this License
+give permission to use their names for publicity for or to assert or
+imply endorsement of any Modified Version.
+
+
+<LI>
+COMBINING DOCUMENTS
+
+
+You may combine the Document with other documents released under this
+License, under the terms defined in section 4 above for modified
+versions, provided that you include in the combination all of the
+Invariant Sections of all of the original documents, unmodified, and
+list them all as Invariant Sections of your combined work in its
+license notice, and that you preserve all their Warranty Disclaimers.
+
+
+The combined work need only contain one copy of this License, and
+multiple identical Invariant Sections may be replaced with a single
+copy. If there are multiple Invariant Sections with the same name but
+different contents, make the title of each such section unique by
+adding at the end of it, in parentheses, the name of the original
+author or publisher of that section if known, or else a unique number.
+Make the same adjustment to the section titles in the list of
+Invariant Sections in the license notice of the combined work.
+
+
+In the combination, you must combine any sections Entitled "History"
+in the various original documents, forming one section Entitled
+"History"; likewise combine any sections Entitled "Acknowledgements",
+and any sections Entitled "Dedications". You must delete all
+sections Entitled "Endorsements."
+
+
+<LI>
+COLLECTIONS OF DOCUMENTS
+
+
+You may make a collection consisting of the Document and other documents
+released under this License, and replace the individual copies of this
+License in the various documents with a single copy that is included in
+the collection, provided that you follow the rules of this License for
+verbatim copying of each of the documents in all other respects.
+
+
+You may extract a single document from such a collection, and distribute
+it individually under this License, provided you insert a copy of this
+License into the extracted document, and follow this License in all
+other respects regarding verbatim copying of that document.
+
+
+<LI>
+AGGREGATION WITH INDEPENDENT WORKS
+
+
+A compilation of the Document or its derivatives with other separate
+and independent documents or works, in or on a volume of a storage or
+distribution medium, is called an "aggregate" if the copyright
+resulting from the compilation is not used to limit the legal rights
+of the compilation's users beyond what the individual works permit.
+When the Document is included in an aggregate, this License does not
+apply to the other works in the aggregate which are not themselves
+derivative works of the Document.
+
+
+If the Cover Text requirement of section 3 is applicable to these
+copies of the Document, then if the Document is less than one half of
+the entire aggregate, the Document's Cover Texts may be placed on
+covers that bracket the Document within the aggregate, or the
+electronic equivalent of covers if the Document is in electronic form.
+Otherwise they must appear on printed covers that bracket the whole
+aggregate.
+
+
+<LI>
+TRANSLATION
+
+
+Translation is considered a kind of modification, so you may
+distribute translations of the Document under the terms of section 4.
+Replacing Invariant Sections with translations requires special
+permission from their copyright holders, but you may include
+translations of some or all Invariant Sections in addition to the
+original versions of these Invariant Sections. You may include a
+translation of this License, and all the license notices in the
+Document, and any Warranty Disclaimers, provided that you also include
+the original English version of this License and the original versions
+of those notices and disclaimers. In case of a disagreement between
+the translation and the original version of this License or a notice
+or disclaimer, the original version will prevail.
+
+
+If a section in the Document is Entitled "Acknowledgements",
+"Dedications", or "History", the requirement (section 4) to Preserve
+its Title (section 1) will typically require changing the actual
+title.
+
+
+<LI>
+TERMINATION
+
+
+You may not copy, modify, sublicense, or distribute the Document
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense, or distribute it is void, and
+will automatically terminate your rights under this License.
+
+
+However, if you cease all violation of this License, then your license
+from a particular copyright holder is reinstated (a) provisionally,
+unless and until the copyright holder explicitly and finally
+terminates your license, and (b) permanently, if the copyright holder
+fails to notify you of the violation by some reasonable means prior to
+60 days after the cessation.
+
+
+Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+
+Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License. If your rights have been terminated and not permanently
+reinstated, receipt of a copy of some or all of the same material does
+not give you any rights to use it.
+
+
+<LI>
+FUTURE REVISIONS OF THIS LICENSE
+
+
+The Free Software Foundation may publish new, revised versions
+of the GNU Free Documentation License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns. See
+<A HREF="http://www.gnu.org/copyleft/">http://www.gnu.org/copyleft/</A>.
+
+
+Each version of the License is given a distinguishing version number.
+If the Document specifies that a particular numbered version of this
+License "or any later version" applies to it, you have the option of
+following the terms and conditions either of that specified version or
+of any later version that has been published (not as a draft) by the
+Free Software Foundation. If the Document does not specify a version
+number of this License, you may choose any version ever published (not
+as a draft) by the Free Software Foundation. If the Document
+specifies that a proxy can decide which future versions of this
+License can be used, that proxy's public statement of acceptance of a
+version permanently authorizes you to choose that version for the
+Document.
+
+
+<LI>
+RELICENSING
+
+
+"Massive Multiauthor Collaboration Site" (or "MMC Site") means any
+World Wide Web server that publishes copyrightable works and also
+provides prominent facilities for anybody to edit those works. A
+public wiki that anybody can edit is an example of such a server. A
+"Massive Multiauthor Collaboration" (or "MMC") contained in the
+site means any set of copyrightable works thus published on the MMC
+site.
+
+
+"CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0
+license published by Creative Commons Corporation, a not-for-profit
+corporation with a principal place of business in San Francisco,
+California, as well as future copyleft versions of that license
+published by that same organization.
+
+
+"Incorporate" means to publish or republish a Document, in whole or
+in part, as part of another Document.
+
+
+An MMC is "eligible for relicensing" if it is licensed under this
+License, and if all works that were first published under this License
+somewhere other than this MMC, and subsequently incorporated in whole
+or in part into the MMC, (1) had no cover texts or invariant sections,
+and (2) were thus incorporated prior to November 1, 2008.
+
+
+The operator of an MMC Site may republish an MMC contained in the site
+under CC-BY-SA on the same site at any time before August 1, 2009,
+provided the MMC is eligible for relicensing.

+<H2> ADDENDUM: How to use this License for your documents </H2>
+
+
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and
+license notices just after the title page:
+
+
+<TABLE><tr><td>&nbsp;</td><td class=smallexample><pre> Copyright (C) <VAR>year</VAR> <VAR>your name</VAR>.
+ Permission is granted to copy, distribute and/or modify this document
+ under the terms of the GNU Free Documentation License, Version 1.3
+ or any later version published by the Free Software Foundation;
+ with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
+ Texts. A copy of the license is included in the section entitled ``GNU
+ Free Documentation License''.
+</pre></td></tr></table>
+
+If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
+replace the "with...Texts." line with this:
+
+
+<TABLE><tr><td>&nbsp;</td><td class=smallexample><pre> with the Invariant Sections being <VAR>list their titles</VAR>, with
+ the Front-Cover Texts being <VAR>list</VAR>, and with the Back-Cover Texts
+ being <VAR>list</VAR>.
+</pre></td></tr></table>
+
+If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+
+
+If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of
+free software license, such as the GNU General Public License,
+to permit their use in free software.

+
+1.1 Introduction to Line Editing
+================================
+
+The following paragraphs describe the notation used to represent
+keystrokes.
+
+ The text 'C-k' is read as 'Control-K' and describes the character
+produced when the <k> key is pressed while the Control key is depressed.
+
+ The text 'M-k' is read as 'Meta-K' and describes the character
+produced when the Meta key (if you have one) is depressed, and the <k>
+key is pressed. The Meta key is labeled <ALT> on many keyboards. On
+keyboards with two keys labeled <ALT> (usually to either side of the
+space bar), the <ALT> on the left side is generally set to work as a
+Meta key. The <ALT> key on the right may also be configured to work as
+a Meta key or may be configured as some other modifier, such as a
+Compose key for typing accented characters.
+
+ If you do not have a Meta or <ALT> key, or another key working as a
+Meta key, the identical keystroke can be generated by typing <ESC>
+_first_, and then typing <k>. Either process is known as "metafying"
+the <k> key.
+
+ The text 'M-C-k' is read as 'Meta-Control-k' and describes the
+character produced by "metafying" 'C-k'.
+
+ In addition, several keys have their own names. Specifically, <DEL>,
+<ESC>, <LFD>, <SPC>, <RET>, and <TAB> all stand for themselves when seen
+in this text, or in an init file (*note Readline Init File::). If your
+keyboard lacks a <LFD> key, typing <C-j> will produce the desired
+character. The <RET> key may be labeled <Return> or <Enter> on some
+keyboards.
+

+
+1.2 Readline Interaction
+========================
+
+Often during an interactive session you type in a long line of text,
+only to notice that the first word on the line is misspelled. The
+Readline library gives you a set of commands for manipulating the text
+as you type it in, allowing you to just fix your typo, and not forcing
+you to retype the majority of the line. Using these editing commands,
+you move the cursor to the place that needs correction, and delete or
+insert the text of the corrections. Then, when you are satisfied with
+the line, you simply press <RET>. You do not have to be at the end of
+the line to press <RET>; the entire line is accepted regardless of the
+location of the cursor within the line.

+File: readline.info, Node: Readline Bare Essentials, Next: Readline Movement Commands, Up: Readline Interaction
+
+1.2.1 Readline Bare Essentials
+------------------------------
+
+In order to enter characters into the line, simply type them. The typed
+character appears where the cursor was, and then the cursor moves one
+space to the right. If you mistype a character, you can use your erase
+character to back up and delete the mistyped character.
+
+ Sometimes you may mistype a character, and not notice the error until
+you have typed several other characters. In that case, you can type
+'C-b' to move the cursor to the left, and then correct your mistake.
+Afterwards, you can move the cursor to the right with 'C-f'.
+
+ When you add text in the middle of a line, you will notice that
+characters to the right of the cursor are 'pushed over' to make room for
+the text that you have inserted. Likewise, when you delete text behind
+the cursor, characters to the right of the cursor are 'pulled back' to
+fill in the blank space created by the removal of the text. A list of
+the bare essentials for editing the text of an input line follows.
+
+'C-b'
+ Move back one character.
+'C-f'
+ Move forward one character.
+<DEL> or <Backspace>
+ Delete the character to the left of the cursor.
+'C-d'
+ Delete the character underneath the cursor.
+Printing characters
+ Insert the character into the line at the cursor.
+'C-_' or 'C-x C-u'
+ Undo the last editing command. You can undo all the way back to an
+ empty line.
+
+(Depending on your configuration, the <Backspace> key be set to delete
+the character to the left of the cursor and the <DEL> key set to delete
+the character underneath the cursor, like 'C-d', rather than the
+character to the left of the cursor.)
+
+&#x1f;
+File: readline.info, Node: Readline Movement Commands, Next: Readline Killing Commands, Prev: Readline Bare Essentials, Up: Readline Interaction
+
+1.2.2 Readline Movement Commands
+--------------------------------
+
+The above table describes the most basic keystrokes that you need in
+order to do editing of the input line. For your convenience, many other
+commands have been added in addition to 'C-b', 'C-f', 'C-d', and <DEL>.
+Here are some commands for moving more rapidly about the line.
+
+'C-a'
+ Move to the start of the line.
+'C-e'
+ Move to the end of the line.
+'M-f'
+ Move forward a word, where a word is composed of letters and
+ digits.
+'M-b'
+ Move backward a word.
+'C-l'
+ Clear the screen, reprinting the current line at the top.
+
+ Notice how 'C-f' moves forward a character, while 'M-f' moves forward
+a word. It is a loose convention that control keystrokes operate on
+characters while meta keystrokes operate on words.
+
+&#x1f;
+File: readline.info, Node: Readline Killing Commands, Next: Readline Arguments, Prev: Readline Movement Commands, Up: Readline Interaction
+
+1.2.3 Readline Killing Commands
+-------------------------------
+
+"Killing" text means to delete the text from the line, but to save it
+away for later use, usually by "yanking" (re-inserting) it back into the
+line. ('Cut' and 'paste' are more recent jargon for 'kill' and 'yank'.)
+
+ If the description for a command says that it 'kills' text, then you
+can be sure that you can get the text back in a different (or the same)
+place later.
+
+ When you use a kill command, the text is saved in a "kill-ring". Any
+number of consecutive kills save all of the killed text together, so
+that when you yank it back, you get it all. The kill ring is not line
+specific; the text that you killed on a previously typed line is
+available to be yanked back later, when you are typing another line.
+
+ Here is the list of commands for killing text.
+
+'C-k'
+ Kill the text from the current cursor position to the end of the
+ line.
+
+'M-d'
+ Kill from the cursor to the end of the current word, or, if between
+ words, to the end of the next word. Word boundaries are the same
+ as those used by 'M-f'.
+
+'M-<DEL>'
+ Kill from the cursor the start of the current word, or, if between
+ words, to the start of the previous word. Word boundaries are the
+ same as those used by 'M-b'.
+
+'C-w'
+ Kill from the cursor to the previous whitespace. This is different
+ than 'M-<DEL>' because the word boundaries differ.
+
+ Here is how to "yank" the text back into the line. Yanking means to
+copy the most-recently-killed text from the kill buffer.
+
+'C-y'
+ Yank the most recently killed text back into the buffer at the
+ cursor.
+
+'M-y'
+ Rotate the kill-ring, and yank the new top. You can only do this
+ if the prior command is 'C-y' or 'M-y'.
+
+&#x1f;
+File: readline.info, Node: Readline Arguments, Next: Searching, Prev: Readline Killing Commands, Up: Readline Interaction
+
+1.2.4 Readline Arguments
+------------------------
+
+You can pass numeric arguments to Readline commands. Sometimes the
+argument acts as a repeat count, other times it is the sign of the
+argument that is significant. If you pass a negative argument to a
+command which normally acts in a forward direction, that command will
+act in a backward direction. For example, to kill text back to the
+start of the line, you might type 'M-- C-k'.
+
+ The general way to pass numeric arguments to a command is to type
+meta digits before the command. If the first 'digit' typed is a minus
+sign ('-'), then the sign of the argument will be negative. Once you
+have typed one meta digit to get the argument started, you can type the
+remainder of the digits, and then the command. For example, to give the
+'C-d' command an argument of 10, you could type 'M-1 0 C-d', which will
+delete the next ten characters on the input line.
+
+&#x1f;
+File: readline.info, Node: Searching, Prev: Readline Arguments, Up: Readline Interaction
+
+1.2.5 Searching for Commands in the History
+-------------------------------------------
+
+Readline provides commands for searching through the command history for
+lines containing a specified string. There are two search modes:
+"incremental" and "non-incremental".
+
+ Incremental searches begin before the user has finished typing the
+search string. As each character of the search string is typed,
+Readline displays the next entry from the history matching the string
+typed so far. An incremental search requires only as many characters as
+needed to find the desired history entry. To search backward in the
+history for a particular string, type 'C-r'. Typing 'C-s' searches
+forward through the history. The characters present in the value of the
+'isearch-terminators' variable are used to terminate an incremental
+search. If that variable has not been assigned a value, the <ESC> and
+'C-J' characters will terminate an incremental search. 'C-g' will abort
+an incremental search and restore the original line. When the search is
+terminated, the history entry containing the search string becomes the
+current line.
+
+ To find other matching entries in the history list, type 'C-r' or
+'C-s' as appropriate. This will search backward or forward in the
+history for the next entry matching the search string typed so far. Any
+other key sequence bound to a Readline command will terminate the search
+and execute that command. For instance, a <RET> will terminate the
+search and accept the line, thereby executing the command from the
+history list. A movement command will terminate the search, make the
+last line found the current line, and begin editing.
+
+ Readline remembers the last incremental search string. If two 'C-r's
+are typed without any intervening characters defining a new search
+string, any remembered search string is used.
+
+ Non-incremental searches read the entire search string before
+starting to search for matching history lines. The search string may be
+typed by the user or be part of the contents of the current line.

+1.3 Readline Init File
+======================
+
+Although the Readline library comes with a set of Emacs-like keybindings
+installed by default, it is possible to use a different set of
+keybindings. Any user can customize programs that use Readline by
+putting commands in an "inputrc" file, conventionally in his home
+directory. The name of this file is taken from the value of the
+environment variable 'INPUTRC'. If that variable is unset, the default
+is '~/.inputrc'. If that file does not exist or cannot be read, the
+ultimate default is '/etc/inputrc'.
+
+ When a program which uses the Readline library starts up, the init
+file is read, and the key bindings are set.
+
+ In addition, the 'C-x C-r' command re-reads this init file, thus
+incorporating any changes that you might have made to it.

+
+1.3.1 Readline Init File Syntax
+-------------------------------
+
+There are only a few basic constructs allowed in the Readline init file.
+Blank lines are ignored. Lines beginning with a '#' are comments.
+Lines beginning with a '$' indicate conditional constructs (*note
+Conditional Init Constructs::). Other lines denote variable settings
+and key bindings.
+
+Variable Settings
+ You can modify the run-time behavior of Readline by altering the
+ values of variables in Readline using the 'set' command within the
+ init file. The syntax is simple:
+
+ set VARIABLE VALUE
+
+ Here, for example, is how to change from the default Emacs-like key
+ binding to use 'vi' line editing commands:
+
+ set editing-mode vi
+
+ Variable names and values, where appropriate, are recognized
+ without regard to case. Unrecognized variable names are ignored.
+
+ Boolean variables (those that can be set to on or off) are set to
+ on if the value is null or empty, ON (case-insensitive), or 1. Any
+ other value results in the variable being set to off.
+
+ A great deal of run-time behavior is changeable with the following
+ variables.
+
+ 'bell-style'
+ Controls what happens when Readline wants to ring the terminal
+ bell. If set to 'none', Readline never rings the bell. If
+ set to 'visible', Readline uses a visible bell if one is
+ available. If set to 'audible' (the default), Readline
+ attempts to ring the terminal's bell.
+
+ 'bind-tty-special-chars'
+ If set to 'on' (the default), Readline attempts to bind the
+ control characters treated specially by the kernel's terminal
+ driver to their Readline equivalents.
+
+ 'blink-matching-paren'
+ If set to 'on', Readline attempts to briefly move the cursor
+ to an opening parenthesis when a closing parenthesis is
+ inserted. The default is 'off'.
+
+ 'colored-completion-prefix'
+ If set to 'on', when listing completions, Readline displays
+ the common prefix of the set of possible completions using a
+ different color. The color definitions are taken from the
+ value of the 'LS_COLORS' environment variable. The default is
+ 'off'.
+
+ 'colored-stats'
+ If set to 'on', Readline displays possible completions using
+ different colors to indicate their file type. The color
+ definitions are taken from the value of the 'LS_COLORS'
+ environment variable. The default is 'off'.
+
+ 'comment-begin'
+ The string to insert at the beginning of the line when the
+ 'insert-comment' command is executed. The default value is
+ '"#"'.
+
+ 'completion-display-width'
+ The number of screen columns used to display possible matches
+ when performing completion. The value is ignored if it is
+ less than 0 or greater than the terminal screen width. A
+ value of 0 will cause matches to be displayed one per line.
+ The default value is -1.
+
+ 'completion-ignore-case'
+ If set to 'on', Readline performs filename matching and
+ completion in a case-insensitive fashion. The default value
+ is 'off'.
+
+ 'completion-map-case'
+ If set to 'on', and COMPLETION-IGNORE-CASE is enabled,
+ Readline treats hyphens ('-') and underscores ('_') as
+ equivalent when performing case-insensitive filename matching
+ and completion. The default value is 'off'.
+
+ 'completion-prefix-display-length'
+ The length in characters of the common prefix of a list of
+ possible completions that is displayed without modification.
+ When set to a value greater than zero, common prefixes longer
+ than this value are replaced with an ellipsis when displaying
+ possible completions.
+
+ 'completion-query-items'
+ The number of possible completions that determines when the
+ user is asked whether the list of possibilities should be
+ displayed. If the number of possible completions is greater
+ than or equal to this value, Readline will ask whether or not
+ the user wishes to view them; otherwise, they are simply
+ listed. This variable must be set to an integer value greater
+ than or equal to 0. A negative value means Readline should
+ never ask. The default limit is '100'.
+
+ 'convert-meta'
+ If set to 'on', Readline will convert characters with the
+ eighth bit set to an ASCII key sequence by stripping the
+ eighth bit and prefixing an <ESC> character, converting them
+ to a meta-prefixed key sequence. The default value is 'on',
+ but will be set to 'off' if the locale is one that contains
+ eight-bit characters.
+
+ 'disable-completion'
+ If set to 'On', Readline will inhibit word completion.
+ Completion characters will be inserted into the line as if
+ they had been mapped to 'self-insert'. The default is 'off'.
+
+ 'echo-control-characters'
+ When set to 'on', on operating systems that indicate they
+ support it, readline echoes a character corresponding to a
+ signal generated from the keyboard. The default is 'on'.
+
+ 'editing-mode'
+ The 'editing-mode' variable controls which default set of key
+ bindings is used. By default, Readline starts up in Emacs
+ editing mode, where the keystrokes are most similar to Emacs.
+ This variable can be set to either 'emacs' or 'vi'.
+
+ 'emacs-mode-string'
+ If the SHOW-MODE-IN-PROMPT variable is enabled, this string is
+ displayed immediately before the last line of the primary
+ prompt when emacs editing mode is active. The value is
+ expanded like a key binding, so the standard set of meta- and
+ control prefixes and backslash escape sequences is available.
+ Use the '\1' and '\2' escapes to begin and end sequences of
+ non-printing characters, which can be used to embed a terminal
+ control sequence into the mode string. The default is '@'.
+
+ 'enable-bracketed-paste'
+ When set to 'On', Readline will configure the terminal in a
+ way that will enable it to insert each paste into the editing
+ buffer as a single string of characters, instead of treating
+ each character as if it had been read from the keyboard. This
+ can prevent pasted characters from being interpreted as
+ editing commands. The default is 'On'.
+
+ 'enable-keypad'
+ When set to 'on', Readline will try to enable the application
+ keypad when it is called. Some systems need this to enable
+ the arrow keys. The default is 'off'.
+
+ 'enable-meta-key'
+ When set to 'on', Readline will try to enable any meta
+ modifier key the terminal claims to support when it is called.
+ On many terminals, the meta key is used to send eight-bit
+ characters. The default is 'on'.
+
+ 'expand-tilde'
+ If set to 'on', tilde expansion is performed when Readline
+ attempts word completion. The default is 'off'.
+
+ 'history-preserve-point'
+ If set to 'on', the history code attempts to place the point
+ (the current cursor position) at the same location on each
+ history line retrieved with 'previous-history' or
+ 'next-history'. The default is 'off'.
+
+ 'history-size'
+ Set the maximum number of history entries saved in the history
+ list. If set to zero, any existing history entries are
+ deleted and no new entries are saved. If set to a value less
+ than zero, the number of history entries is not limited. By
+ default, the number of history entries is not limited. If an
+ attempt is made to set HISTORY-SIZE to a non-numeric value,
+ the maximum number of history entries will be set to 500.
+
+ 'horizontal-scroll-mode'
+ This variable can be set to either 'on' or 'off'. Setting it
+ to 'on' means that the text of the lines being edited will
+ scroll horizontally on a single screen line when they are
+ longer than the width of the screen, instead of wrapping onto
+ a new screen line. This variable is automatically set to 'on'
+ for terminals of height 1. By default, this variable is set
+ to 'off'.
+
+ 'input-meta'
+ If set to 'on', Readline will enable eight-bit input (it will
+ not clear the eighth bit in the characters it reads),
+ regardless of what the terminal claims it can support. The
+ default value is 'off', but Readline will set it to 'on' if
+ the locale contains eight-bit characters. The name
+ 'meta-flag' is a synonym for this variable.
+
+ 'isearch-terminators'
+ The string of characters that should terminate an incremental
+ search without subsequently executing the character as a
+ command (*note Searching::). If this variable has not been
+ given a value, the characters <ESC> and 'C-J' will terminate
+ an incremental search.
+
+ 'keymap'
+ Sets Readline's idea of the current keymap for key binding
+ commands. Built-in 'keymap' names are 'emacs',
+ 'emacs-standard', 'emacs-meta', 'emacs-ctlx', 'vi', 'vi-move',
+ 'vi-command', and 'vi-insert'. 'vi' is equivalent to
+ 'vi-command' ('vi-move' is also a synonym); 'emacs' is
+ equivalent to 'emacs-standard'. Applications may add
+ additional names. The default value is 'emacs'. The value of
+ the 'editing-mode' variable also affects the default keymap.
+
+ 'keyseq-timeout'
+ Specifies the duration Readline will wait for a character when
+ reading an ambiguous key sequence (one that can form a
+ complete key sequence using the input read so far, or can take
+ additional input to complete a longer key sequence). If no
+ input is received within the timeout, Readline will use the
+ shorter but complete key sequence. Readline uses this value
+ to determine whether or not input is available on the current
+ input source ('rl_instream' by default). The value is
+ specified in milliseconds, so a value of 1000 means that
+ Readline will wait one second for additional input. If this
+ variable is set to a value less than or equal to zero, or to a
+ non-numeric value, Readline will wait until another key is
+ pressed to decide which key sequence to complete. The default
+ value is '500'.
+
+ 'mark-directories'
+ If set to 'on', completed directory names have a slash
+ appended. The default is 'on'.
+
+ 'mark-modified-lines'
+ This variable, when set to 'on', causes Readline to display an
+ asterisk ('*') at the start of history lines which have been
+ modified. This variable is 'off' by default.
+
+ 'mark-symlinked-directories'
+ If set to 'on', completed names which are symbolic links to
+ directories have a slash appended (subject to the value of
+ 'mark-directories'). The default is 'off'.
+
+ 'match-hidden-files'
+ This variable, when set to 'on', causes Readline to match
+ files whose names begin with a '.' (hidden files) when
+ performing filename completion. If set to 'off', the leading
+ '.' must be supplied by the user in the filename to be
+ completed. This variable is 'on' by default.
+
+ 'menu-complete-display-prefix'
+ If set to 'on', menu completion displays the common prefix of
+ the list of possible completions (which may be empty) before
+ cycling through the list. The default is 'off'.
+
+ 'output-meta'
+ If set to 'on', Readline will display characters with the
+ eighth bit set directly rather than as a meta-prefixed escape
+ sequence. The default is 'off', but Readline will set it to
+ 'on' if the locale contains eight-bit characters.
+
+ 'page-completions'
+ If set to 'on', Readline uses an internal 'more'-like pager to
+ display a screenful of possible completions at a time. This
+ variable is 'on' by default.
+
+ 'print-completions-horizontally'
+ If set to 'on', Readline will display completions with matches
+ sorted horizontally in alphabetical order, rather than down
+ the screen. The default is 'off'.
+
+ 'revert-all-at-newline'
+ If set to 'on', Readline will undo all changes to history
+ lines before returning when 'accept-line' is executed. By
+ default, history lines may be modified and retain individual
+ undo lists across calls to 'readline'. The default is 'off'.
+
+ 'show-all-if-ambiguous'
+ This alters the default behavior of the completion functions.
+ If set to 'on', words which have more than one possible
+ completion cause the matches to be listed immediately instead
+ of ringing the bell. The default value is 'off'.
+
+ 'show-all-if-unmodified'
+ This alters the default behavior of the completion functions
+ in a fashion similar to SHOW-ALL-IF-AMBIGUOUS. If set to
+ 'on', words which have more than one possible completion
+ without any possible partial completion (the possible
+ completions don't share a common prefix) cause the matches to
+ be listed immediately instead of ringing the bell. The
+ default value is 'off'.
+
+ 'show-mode-in-prompt'
+ If set to 'on', add a string to the beginning of the prompt
+ indicating the editing mode: emacs, vi command, or vi
+ insertion. The mode strings are user-settable (e.g.,
+ EMACS-MODE-STRING). The default value is 'off'.
+
+ 'skip-completed-text'
+ If set to 'on', this alters the default completion behavior
+ when inserting a single match into the line. It's only active
+ when performing completion in the middle of a word. If
+ enabled, readline does not insert characters from the
+ completion that match characters after point in the word being
+ completed, so portions of the word following the cursor are
+ not duplicated. For instance, if this is enabled, attempting
+ completion when the cursor is after the 'e' in 'Makefile' will
+ result in 'Makefile' rather than 'Makefilefile', assuming
+ there is a single possible completion. The default value is
+ 'off'.
+
+ 'vi-cmd-mode-string'
+ If the SHOW-MODE-IN-PROMPT variable is enabled, this string is
+ displayed immediately before the last line of the primary
+ prompt when vi editing mode is active and in command mode.
+ The value is expanded like a key binding, so the standard set
+ of meta- and control prefixes and backslash escape sequences
+ is available. Use the '\1' and '\2' escapes to begin and end
+ sequences of non-printing characters, which can be used to
+ embed a terminal control sequence into the mode string. The
+ default is '(cmd)'.
+
+ 'vi-ins-mode-string'
+ If the SHOW-MODE-IN-PROMPT variable is enabled, this string is
+ displayed immediately before the last line of the primary
+ prompt when vi editing mode is active and in insertion mode.
+ The value is expanded like a key binding, so the standard set
+ of meta- and control prefixes and backslash escape sequences
+ is available. Use the '\1' and '\2' escapes to begin and end
+ sequences of non-printing characters, which can be used to
+ embed a terminal control sequence into the mode string. The
+ default is '(ins)'.
+
+ 'visible-stats'
+ If set to 'on', a character denoting a file's type is appended
+ to the filename when listing possible completions. The
+ default is 'off'.
+
+Key Bindings
+ The syntax for controlling key bindings in the init file is simple.
+ First you need to find the name of the command that you want to
+ change. The following sections contain tables of the command name,
+ the default keybinding, if any, and a short description of what the
+ command does.
+
+ Once you know the name of the command, simply place on a line in
+ the init file the name of the key you wish to bind the command to,
+ a colon, and then the name of the command. There can be no space
+ between the key name and the colon - that will be interpreted as
+ part of the key name. The name of the key can be expressed in
+ different ways, depending on what you find most comfortable.
+
+ In addition to command names, readline allows keys to be bound to a
+ string that is inserted when the key is pressed (a MACRO).
+
+ KEYNAME: FUNCTION-NAME or MACRO
+ KEYNAME is the name of a key spelled out in English. For
+ example:
+ Control-u: universal-argument
+ Meta-Rubout: backward-kill-word
+ Control-o: "> output"
+
+ In the example above, 'C-u' is bound to the function
+ 'universal-argument', 'M-DEL' is bound to the function
+ 'backward-kill-word', and 'C-o' is bound to run the macro
+ expressed on the right hand side (that is, to insert the text
+ '> output' into the line).
+
+ A number of symbolic character names are recognized while
+ processing this key binding syntax: DEL, ESC, ESCAPE, LFD,
+ NEWLINE, RET, RETURN, RUBOUT, SPACE, SPC, and TAB.
+
+ "KEYSEQ": FUNCTION-NAME or MACRO
+ KEYSEQ differs from KEYNAME above in that strings denoting an
+ entire key sequence can be specified, by placing the key
+ sequence in double quotes. Some GNU Emacs style key escapes
+ can be used, as in the following example, but the special
+ character names are not recognized.
+
+ "\C-u": universal-argument
+ "\C-x\C-r": re-read-init-file
+ "\e11~": "Function Key 1"
+
+ In the above example, 'C-u' is again bound to the function
+ 'universal-argument' (just as it was in the first example),
+ ''C-x' 'C-r'' is bound to the function 're-read-init-file',
+ and '<ESC> <> <1> <1> <~>' is bound to insert the text
+ 'Function Key 1'.
+
+ The following GNU Emacs style escape sequences are available when
+ specifying key sequences:
+
+ '\C-'
+ control prefix
+ '\M-'
+ meta prefix
+ '\e'
+ an escape character
+ '\\'
+ backslash
+ '\"'
+ <">, a double quotation mark
+ '\''
+ <'>, a single quote or apostrophe
+
+ In addition to the GNU Emacs style escape sequences, a second set
+ of backslash escapes is available:
+
+ '\a'
+ alert (bell)
+ '\b'
+ backspace
+ '\d'
+ delete
+ '\f'
+ form feed
+ '\n'
+ newline
+ '\r'
+ carriage return
+ '\t'
+ horizontal tab
+ '\v'
+ vertical tab
+ '\NNN'
+ the eight-bit character whose value is the octal value NNN
+ (one to three digits)
+ '\xHH'
+ the eight-bit character whose value is the hexadecimal value
+ HH (one or two hex digits)
+
+ When entering the text of a macro, single or double quotes must be
+ used to indicate a macro definition. Unquoted text is assumed to
+ be a function name. In the macro body, the backslash escapes
+ described above are expanded. Backslash will quote any other
+ character in the macro text, including '"' and '''. For example,
+ the following binding will make ''C-x' \' insert a single '\' into
+ the line:
+ "\C-x\\": "\\"
+

+
+1.3.2 Conditional Init Constructs
+---------------------------------
+
+Readline implements a facility similar in spirit to the conditional
+compilation features of the C preprocessor which allows key bindings and
+variable settings to be performed as the result of tests. There are
+four parser directives used.
+
+'$if'
+ The '$if' construct allows bindings to be made based on the editing
+ mode, the terminal being used, or the application using Readline.
+ The text of the test, after any comparison operator, extends to the
+ end of the line; unless otherwise noted, no characters are required
+ to isolate it.
+
+ 'mode'
+ The 'mode=' form of the '$if' directive is used to test
+ whether Readline is in 'emacs' or 'vi' mode. This may be used
+ in conjunction with the 'set keymap' command, for instance, to
+ set bindings in the 'emacs-standard' and 'emacs-ctlx' keymaps
+ only if Readline is starting out in 'emacs' mode.
+
+ 'term'
+ The 'term=' form may be used to include terminal-specific key
+ bindings, perhaps to bind the key sequences output by the
+ terminal's function keys. The word on the right side of the
+ '=' is tested against both the full name of the terminal and
+ the portion of the terminal name before the first '-'. This
+ allows 'sun' to match both 'sun' and 'sun-cmd', for instance.
+
+ 'version'
+ The 'version' test may be used to perform comparisons against
+ specific Readline versions. The 'version' expands to the
+ current Readline version. The set of comparison operators
+ includes '=' (and '=='), '!=', '<=', '>=', '<', and '>'. The
+ version number supplied on the right side of the operator
+ consists of a major version number, an optional decimal point,
+ and an optional minor version (e.g., '7.1'). If the minor
+ version is omitted, it is assumed to be '0'. The operator may
+ be separated from the string 'version' and from the version
+ number argument by whitespace. The following example sets a
+ variable if the Readline version being used is 7.0 or newer:
+ $if version >= 7.0
+ set show-mode-in-prompt on
+ $endif
+
+ 'application'
+ The APPLICATION construct is used to include
+ application-specific settings. Each program using the
+ Readline library sets the APPLICATION NAME, and you can test
+ for a particular value. This could be used to bind key
+ sequences to functions useful for a specific program. For
+ instance, the following command adds a key sequence that
+ quotes the current or previous word in Bash:
+ $if Bash
+ # Quote the current or previous word
+ "\C-xq": "\eb\"\ef\""
+ $endif
+
+ 'variable'
+ The VARIABLE construct provides simple equality tests for
+ Readline variables and values. The permitted comparison
+ operators are '=', '==', and '!='. The variable name must be
+ separated from the comparison operator by whitespace; the
+ operator may be separated from the value on the right hand
+ side by whitespace. Both string and boolean variables may be
+ tested. Boolean variables must be tested against the values
+ ON and OFF. The following example is equivalent to the
+ 'mode=emacs' test described above:
+ $if editing-mode == emacs
+ set show-mode-in-prompt on
+ $endif
+
+'$endif'
+ This command, as seen in the previous example, terminates an '$if'
+ command.
+
+'$else'
+ Commands in this branch of the '$if' directive are executed if the
+ test fails.
+
+'$include'
+ This directive takes a single filename as an argument and reads
+ commands and bindings from that file. For example, the following
+ directive reads from '/etc/inputrc':
+ $include /etc/inputrc
+

+'forward-char (C-f)'
+ Move forward a character.
+
+'backward-char (C-b)'

+
+1.4.2 Commands For Manipulating The History
+-------------------------------------------
+
+'accept-line (Newline or Return)'
+ Accept the line regardless of where the cursor is. If this line is
+ non-empty, it may be added to the history list for future recall
+ with 'add_history()'. If this line is a modified history line, the
+ history line is restored to its original state.
+
+'previous-history (C-p)'
+ Move 'back' through the history list, fetching the previous
+ command.
+
+'next-history (C-n)'
+ Move 'forward' through the history list, fetching the next command.
+
+'beginning-of-history (M-<)'
+ Move to the first line in the history.
+
+'end-of-history (M->)'
+ Move to the end of the input history, i.e., the line currently
+ being entered.
+
+'reverse-search-history (C-r)'
+ Search backward starting at the current line and moving 'up'
+ through the history as necessary. This is an incremental search.
+ This command sets the region to the matched text and activates the
+ mark.
+
+'forward-search-history (C-s)'
+ Search forward starting at the current line and moving 'down'
+ through the history as necessary. This is an incremental search.
+ This command sets the region to the matched text and activates the
+ mark.
+
+'non-incremental-reverse-search-history (M-p)'
+ Search backward starting at the current line and moving 'up'
+ through the history as necessary using a non-incremental search for
+ a string supplied by the user. The search string may match
+ anywhere in a history line.
+
+'non-incremental-forward-search-history (M-n)'
+ Search forward starting at the current line and moving 'down'
+ through the history as necessary using a non-incremental search for
+ a string supplied by the user. The search string may match
+ anywhere in a history line.
+
+'history-search-forward ()'
+ Search forward through the history for the string of characters
+ between the start of the current line and the point. The search
+ string must match at the beginning of a history line. This is a
+ non-incremental search. By default, this command is unbound.
+
+'history-search-backward ()'
+ Search backward through the history for the string of characters
+ between the start of the current line and the point. The search
+ string must match at the beginning of a history line. This is a
+ non-incremental search. By default, this command is unbound.
+
+'history-substring-search-forward ()'
+ Search forward through the history for the string of characters
+ between the start of the current line and the point. The search
+ string may match anywhere in a history line. This is a
+ non-incremental search. By default, this command is unbound.
+
+'history-substring-search-backward ()'
+ Search backward through the history for the string of characters
+ between the start of the current line and the point. The search
+ string may match anywhere in a history line. This is a
+ non-incremental search. By default, this command is unbound.
+
+'yank-nth-arg (M-C-y)'
+ Insert the first argument to the previous command (usually the
+ second word on the previous line) at point. With an argument N,
+ insert the Nth word from the previous command (the words in the
+ previous command begin with word 0). A negative argument inserts
+ the Nth word from the end of the previous command. Once the
+ argument N is computed, the argument is extracted as if the '!N'
+ history expansion had been specified.
+
+'yank-last-arg (M-. or M-_)'
+ Insert last argument to the previous command (the last word of the
+ previous history entry). With a numeric argument, behave exactly
+ like 'yank-nth-arg'. Successive calls to 'yank-last-arg' move back
+ through the history list, inserting the last word (or the word
+ specified by the argument to the first call) of each line in turn.
+ Any numeric argument supplied to these successive calls determines
+ the direction to move through the history. A negative argument
+ switches the direction through the history (back or forward). The
+ history expansion facilities are used to extract the last argument,
+ as if the '!$' history expansion had been specified.
+
+'operate-and-get-next (C-o)'
+ Accept the current line for return to the calling application as if
+ a newline had been entered, and fetch the next line relative to the
+ current line from the history for editing. A numeric argument, if
+ supplied, specifies the history entry to use instead of the current
+ line.
+
+&#x1f;
+File: readline.info, Node: Commands For Text, Next: Commands For Killing, Prev: Commands For History, Up: Bindable Readline Commands
+
+1.4.3 Commands For Changing Text
+--------------------------------
+
+'end-of-file (usually C-d)'
+ The character indicating end-of-file as set, for example, by
+ 'stty'. If this character is read when there are no characters on
+ the line, and point is at the beginning of the line, Readline
+ interprets it as the end of input and returns EOF.
+
+'delete-char (C-d)'
+ Delete the character at point. If this function is bound to the
+ same character as the tty EOF character, as 'C-d' commonly is, see
+ above for the effects.
+
+'backward-delete-char (Rubout)'
+ Delete the character behind the cursor. A numeric argument means
+ to kill the characters instead of deleting them.
+
+'forward-backward-delete-char ()'
+ Delete the character under the cursor, unless the cursor is at the
+ end of the line, in which case the character behind the cursor is
+ deleted. By default, this is not bound to a key.
+
+'quoted-insert (C-q or C-v)'
+ Add the next character typed to the line verbatim. This is how to
+ insert key sequences like 'C-q', for example.
+
+'tab-insert (M-<TAB>)'
+ Insert a tab character.
+
+'self-insert (a, b, A, 1, !, ...)'
+ Insert yourself.
+
+'bracketed-paste-begin ()'
+ This function is intended to be bound to the "bracketed paste"
+ escape sequence sent by some terminals, and such a binding is
+ assigned by default. It allows Readline to insert the pasted text
+ as a single unit without treating each character as if it had been
+ read from the keyboard. The characters are inserted as if each one
+ was bound to 'self-insert' instead of executing any editing
+ commands.
+
+ Bracketed paste sets the region (the characters between point and
+ the mark) to the inserted text. It uses the concept of an _active
+ mark_: when the mark is active, Readline redisplay uses the
+ terminal's standout mode to denote the region.
+
+'transpose-chars (C-t)'
+ Drag the character before the cursor forward over the character at
+ the cursor, moving the cursor forward as well. If the insertion
+ point is at the end of the line, then this transposes the last two
+ characters of the line. Negative arguments have no effect.
+
+'transpose-words (M-t)'
+ Drag the word before point past the word after point, moving point
+ past that word as well. If the insertion point is at the end of
+ the line, this transposes the last two words on the line.
+
+'upcase-word (M-u)'
+ Uppercase the current (or following) word. With a negative
+ argument, uppercase the previous word, but do not move the cursor.
+
+'downcase-word (M-l)'
+ Lowercase the current (or following) word. With a negative
+ argument, lowercase the previous word, but do not move the cursor.
+
+'capitalize-word (M-c)'
+ Capitalize the current (or following) word. With a negative
+ argument, capitalize the previous word, but do not move the cursor.
+
+'overwrite-mode ()'
+ Toggle overwrite mode. With an explicit positive numeric argument,
+ switches to overwrite mode. With an explicit non-positive numeric
+ argument, switches to insert mode. This command affects only
+ 'emacs' mode; 'vi' mode does overwrite differently. Each call to
+ 'readline()' starts in insert mode.
+
+ In overwrite mode, characters bound to 'self-insert' replace the
+ text at point rather than pushing the text to the right.
+ Characters bound to 'backward-delete-char' replace the character
+ before point with a space.
+
+ By default, this command is unbound.

+
+1.4.4 Killing And Yanking
+-------------------------
+
+'kill-line (C-k)'
+ Kill the text from point to the end of the line. With a negative
+ numeric argument, kill backward from the cursor to the beginning of
+ the current line.
+
+'backward-kill-line (C-x Rubout)'
+ Kill backward from the cursor to the beginning of the current line.
+ With a negative numeric argument, kill forward from the cursor to
+ the end of the current line.
+
+'unix-line-discard (C-u)'
+ Kill backward from the cursor to the beginning of the current line.
+
+'kill-whole-line ()'
+ Kill all characters on the current line, no matter where point is.
+ By default, this is unbound.
+
+'kill-word (M-d)'
+ Kill from point to the end of the current word, or if between
+ words, to the end of the next word. Word boundaries are the same
+ as 'forward-word'.
+
+'backward-kill-word (M-<DEL>)'
+ Kill the word behind point. Word boundaries are the same as
+ 'backward-word'.
+
+'shell-transpose-words (M-C-t)'
+ Drag the word before point past the word after point, moving point
+ past that word as well. If the insertion point is at the end of
+ the line, this transposes the last two words on the line. Word
+ boundaries are the same as 'shell-forward-word' and
+ 'shell-backward-word'.
+
+'unix-word-rubout (C-w)'
+ Kill the word behind point, using white space as a word boundary.
+ The killed text is saved on the kill-ring.
+
+'unix-filename-rubout ()'
+ Kill the word behind point, using white space and the slash
+ character as the word boundaries. The killed text is saved on the
+ kill-ring.
+
+'delete-horizontal-space ()'
+ Delete all spaces and tabs around point. By default, this is
+ unbound.
+
+'kill-region ()'
+ Kill the text in the current region. By default, this command is
+ unbound.
+
+'copy-region-as-kill ()'
+ Copy the text in the region to the kill buffer, so it can be yanked
+ right away. By default, this command is unbound.
+
+'copy-backward-word ()'
+ Copy the word before point to the kill buffer. The word boundaries
+ are the same as 'backward-word'. By default, this command is
+ unbound.
+
+'copy-forward-word ()'
+ Copy the word following point to the kill buffer. The word
+ boundaries are the same as 'forward-word'. By default, this
+ command is unbound.
+
+'yank (C-y)'
+ Yank the top of the kill ring into the buffer at point.
+
+'yank-pop (M-y)'
+ Rotate the kill-ring, and yank the new top. You can only do this
+ if the prior command is 'yank' or 'yank-pop'.
+
+&#x1f;
+File: readline.info, Node: Numeric Arguments, Next: Commands For Completion, Prev: Commands For Killing, Up: Bindable Readline Commands
+
+1.4.5 Specifying Numeric Arguments
+----------------------------------
+
+'digit-argument (M-0, M-1, ... M--)'
+ Add this digit to the argument already accumulating, or start a new
+ argument. 'M--' starts a negative argument.
+
+'universal-argument ()'
+ This is another way to specify an argument. If this command is
+ followed by one or more digits, optionally with a leading minus
+ sign, those digits define the argument. If the command is followed
+ by digits, executing 'universal-argument' again ends the numeric
+ argument, but is otherwise ignored. As a special case, if this
+ command is immediately followed by a character that is neither a
+ digit nor minus sign, the argument count for the next command is
+ multiplied by four. The argument count is initially one, so
+ executing this function the first time makes the argument count
+ four, a second time makes the argument count sixteen, and so on.
+ By default, this is not bound to a key.
+
+&#x1f;
+File: readline.info, Node: Commands For Completion, Next: Keyboard Macros, Prev: Numeric Arguments, Up: Bindable Readline Commands
+
+1.4.6 Letting Readline Type For You
+-----------------------------------
+
+'complete (<TAB>)'
+ Attempt to perform completion on the text before point. The actual
+ completion performed is application-specific. The default is
+ filename completion.
+
+'possible-completions (M-?)'
+ List the possible completions of the text before point. When
+ displaying completions, Readline sets the number of columns used
+ for display to the value of 'completion-display-width', the value
+ of the environment variable 'COLUMNS', or the screen width, in that
+ order.
+
+'insert-completions (M-*)'
+ Insert all completions of the text before point that would have
+ been generated by 'possible-completions'.
+
+'menu-complete ()'
+ Similar to 'complete', but replaces the word to be completed with a
+ single match from the list of possible completions. Repeated
+ execution of 'menu-complete' steps through the list of possible
+ completions, inserting each match in turn. At the end of the list
+ of completions, the bell is rung (subject to the setting of
+ 'bell-style') and the original text is restored. An argument of N
+ moves N positions forward in the list of matches; a negative
+ argument may be used to move backward through the list. This
+ command is intended to be bound to <TAB>, but is unbound by
+ default.
+
+'menu-complete-backward ()'
+ Identical to 'menu-complete', but moves backward through the list
+ of possible completions, as if 'menu-complete' had been given a
+ negative argument.
+
+'delete-char-or-list ()'
+ Deletes the character under the cursor if not at the beginning or
+ end of the line (like 'delete-char'). If at the end of the line,
+ behaves identically to 'possible-completions'. This command is
+ unbound by default.
+
+&#x1f;
+File: readline.info, Node: Keyboard Macros, Next: Miscellaneous Commands, Prev: Commands For Completion, Up: Bindable Readline Commands
+
+1.4.7 Keyboard Macros
+---------------------
+
+'start-kbd-macro (C-x ()'
+ Begin saving the characters typed into the current keyboard macro.
+
+'end-kbd-macro (C-x ))'
+ Stop saving the characters typed into the current keyboard macro
+ and save the definition.
+
+'call-last-kbd-macro (C-x e)'
+ Re-execute the last keyboard macro defined, by making the
+ characters in the macro appear as if typed at the keyboard.
+
+'print-last-kbd-macro ()'
+ Print the last keboard macro defined in a format suitable for the
+ INPUTRC file.
+
+&#x1f;
+File: readline.info, Node: Miscellaneous Commands, Prev: Keyboard Macros, Up: Bindable Readline Commands
+
+1.4.8 Some Miscellaneous Commands
+---------------------------------
+
+'re-read-init-file (C-x C-r)'
+ Read in the contents of the INPUTRC file, and incorporate any
+ bindings or variable assignments found there.
+
+'abort (C-g)'
+ Abort the current editing command and ring the terminal's bell
+ (subject to the setting of 'bell-style').
+
+'do-lowercase-version (M-A, M-B, M-X, ...)'
+ If the metafied character X is upper case, run the command that is
+ bound to the corresponding metafied lower case character. The
+ behavior is undefined if X is already lower case.
+
+'prefix-meta (<ESC>)'
+ Metafy the next character typed. This is for keyboards without a
+ meta key. Typing '<ESC> f' is equivalent to typing 'M-f'.
+
+'undo (C-_ or C-x C-u)'
+ Incremental undo, separately remembered for each line.
+
+'revert-line (M-r)'
+ Undo all changes made to this line. This is like executing the
+ 'undo' command enough times to get back to the beginning.
+
+'tilde-expand (M-~)'
+ Perform tilde expansion on the current word.
+
+'set-mark (C-@)'
+ Set the mark to the point. If a numeric argument is supplied, the
+ mark is set to that position.
+
+'exchange-point-and-mark (C-x C-x)'
+ Swap the point with the mark. The current cursor position is set
+ to the saved position, and the old cursor position is saved as the
+ mark.
+
+'character-search (C-)'
+ A character is read and point is moved to the next occurrence of
+ that character. A negative count searches for previous
+ occurrences.
+
+'character-search-backward (M-C-)'
+ A character is read and point is moved to the previous occurrence
+ of that character. A negative count searches for subsequent
+ occurrences.
+
+'skip-csi-sequence ()'
+ Read enough characters to consume a multi-key sequence such as
+ those defined for keys like Home and End. Such sequences begin
+ with a Control Sequence Indicator (CSI), usually ESC-. If this
+ sequence is bound to "\e", keys producing such sequences will have
+ no effect unless explicitly bound to a readline command, instead of
+ inserting stray characters into the editing buffer. This is
+ unbound by default, but usually bound to ESC-.
+
+'insert-comment (M-#)'
+ Without a numeric argument, the value of the 'comment-begin'
+ variable is inserted at the beginning of the current line. If a
+ numeric argument is supplied, this command acts as a toggle: if the
+ characters at the beginning of the line do not match the value of
+ 'comment-begin', the value is inserted, otherwise the characters in
+ 'comment-begin' are deleted from the beginning of the line. In
+ either case, the line is accepted as if a newline had been typed.
+
+'dump-functions ()'
+ Print all of the functions and their key bindings to the Readline
+ output stream. If a numeric argument is supplied, the output is
+ formatted in such a way that it can be made part of an INPUTRC
+ file. This command is unbound by default.
+
+'dump-variables ()'
+ Print all of the settable variables and their values to the
+ Readline output stream. If a numeric argument is supplied, the
+ output is formatted in such a way that it can be made part of an
+ INPUTRC file. This command is unbound by default.
+
+'dump-macros ()'
+ Print all of the Readline key sequences bound to macros and the
+ strings they output. If a numeric argument is supplied, the output
+ is formatted in such a way that it can be made part of an INPUTRC
+ file. This command is unbound by default.
+
+'emacs-editing-mode (C-e)'
+ When in 'vi' command mode, this causes a switch to 'emacs' editing
+ mode.
+
+'vi-editing-mode (M-C-j)'
+ When in 'emacs' editing mode, this causes a switch to 'vi' editing
+ mode.
+
+&#x1f;
+File: readline.info, Node: Readline vi Mode, Prev: Bindable Readline Commands, Up: Command Line Editing
+
+1.5 Readline vi Mode
+====================
+
+While the Readline library does not have a full set of 'vi' editing
+functions, it does contain enough to allow simple editing of the line.
+The Readline 'vi' mode behaves as specified in the POSIX standard.
+
+ In order to switch interactively between 'emacs' and 'vi' editing
+modes, use the command 'M-C-j' (bound to emacs-editing-mode when in 'vi'
+mode and to vi-editing-mode in 'emacs' mode). The Readline default is
+'emacs' mode.
+
+ When you enter a line in 'vi' mode, you are already placed in
+'insertion' mode, as if you had typed an 'i'. Pressing <ESC> switches
+you into 'command' mode, where you can edit the text of the line with
+the standard 'vi' movement keys, move to previous history lines with 'k'
+and subsequent lines with 'j', and so forth.

+File: readline.info, Node: Basic Behavior, Next: Custom Functions, Up: Programming with GNU Readline
+
+2.1 Basic Behavior
+==================
+
+Many programs provide a command line interface, such as 'mail', 'ftp',
+and 'sh'. For such programs, the default behaviour of Readline is
+sufficient. This section describes how to use Readline in the simplest
+way possible, perhaps to replace calls in your code to 'gets()' or
+'fgets()'.
+
+ The function 'readline()' prints a prompt PROMPT and then reads and
+returns a single line of text from the user. If PROMPT is 'NULL' or the
+empty string, no prompt is displayed. The line 'readline' returns is
+allocated with 'malloc()'; the caller should 'free()' the line when it
+has finished with it. The declaration for 'readline' in ANSI C is
+
+ char *readline (const char *PROMPT);
+
+So, one might say
+ char *line = readline ("Enter a line: ");
+in order to read a line of text from the user. The line returned has
+the final newline removed, so only the text remains.
+
+ If 'readline' encounters an 'EOF' while reading the line, and the
+line is empty at that point, then '(char *)NULL' is returned.
+Otherwise, the line is ended just as if a newline had been typed.
+
+ Readline performs some expansion on the PROMPT before it is displayed
+on the screen. See the description of 'rl_expand_prompt' (*note
+Redisplay::) for additional details, especially if PROMPT will contain
+characters that do not consume physical screen space when displayed.
+
+ If you want the user to be able to get at the line later, (with <C-p>
+for example), you must call 'add_history()' to save the line away in a
+"history" list of such lines.
+
+ add_history (line);
+
+For full details on the GNU History Library, see the associated manual.
+
+ It is preferable to avoid saving empty lines on the history list,
+since users rarely have a burning need to reuse a blank line. Here is a
+function which usefully replaces the standard 'gets()' library function,
+and has the advantage of no static buffer to overflow:
+
+ /* A static variable for holding the line. */
+ static char *line_read = (char *)NULL;
+
+ /* Read a string, and return a pointer to it.
+ Returns NULL on EOF. */
+ char *
+ rl_gets ()
+ {
+ /* If the buffer has already been allocated,
+ return the memory to the free pool. */
+ if (line_read)
+ {
+ free (line_read);
+ line_read = (char *)NULL;
+ }
+
+ /* Get a line from the user. */
+ line_read = readline ("");
+
+ /* If the line has any text in it,
+ save it on the history. */
+ if (line_read && *line_read)
+ add_history (line_read);
+
+ return (line_read);
+ }
+
+ This function gives the user the default behaviour of <TAB>
+completion: completion on file names. If you do not want Readline to
+complete on filenames, you can change the binding of the <TAB> key with
+'rl_bind_key()'.
+
+ int rl_bind_key (int KEY, rl_command_func_t *FUNCTION);
+
+ 'rl_bind_key()' takes two arguments: KEY is the character that you
+want to bind, and FUNCTION is the address of the function to call when
+KEY is pressed. Binding <TAB> to 'rl_insert()' makes <TAB> insert
+itself. 'rl_bind_key()' returns non-zero if KEY is not a valid ASCII
+character code (between 0 and 255).
+
+ Thus, to disable the default <TAB> behavior, the following suffices:
+ rl_bind_key ('\t', rl_insert);
+
+ This code should be executed once at the start of your program; you
+might write a function called 'initialize_readline()' which performs
+this and other desired initializations, such as installing custom
+completers (*note Custom Completers::).
+
+&#x1f;
+File: readline.info, Node: Custom Functions, Next: Readline Variables, Prev: Basic Behavior, Up: Programming with GNU Readline
+
+2.2 Custom Functions
+====================
+
+Readline provides many functions for manipulating the text of the line,
+but it isn't possible to anticipate the needs of all programs. This
+section describes the various functions and variables defined within the
+Readline library which allow a user program to add customized
+functionality to Readline.
+
+ Before declaring any functions that customize Readline's behavior, or
+using any functionality Readline provides in other code, an application
+writer should include the file '<readline/readline.h>' in any file that
+uses Readline's features. Since some of the definitions in 'readline.h'
+use the 'stdio' library, the file '<stdio.h>' should be included before
+'readline.h'.
+
+ 'readline.h' defines a C preprocessor variable that should be treated
+as an integer, 'RL_READLINE_VERSION', which may be used to conditionally
+compile application code depending on the installed Readline version.
+The value is a hexadecimal encoding of the major and minor version

+
+2.2.1 Readline Typedefs
+-----------------------
+
+For readability, we declare a number of new object types, all pointers
+to functions.
+
+ The reason for declaring these new types is to make it easier to
+write code describing pointers to C functions with appropriately
+prototyped arguments and return values.
+
+ For instance, say we want to declare a variable FUNC as a pointer to
+a function which takes two 'int' arguments and returns an 'int' (this is
+the type of all of the Readline bindable functions). Instead of the
+classic C declaration
+
+ 'int (*func)();'
+
+or the ANSI-C style declaration
+
+ 'int (*func)(int, int);'
+
+we may write
+
+ 'rl_command_func_t *func;'
+
+ The full list of function pointer types available is
+
+'typedef int rl_command_func_t (int, int);'
+
+'typedef char *rl_compentry_func_t (const char *, int);'
+
+'typedef char **rl_completion_func_t (const char *, int, int);'
+
+'typedef char *rl_quote_func_t (char *, int, char *);'
+
+'typedef char *rl_dequote_func_t (char *, int);'

+
+2.2.2 Writing a New Function
+----------------------------
+
+In order to write new functions for Readline, you need to know the
+calling conventions for keyboard-invoked functions, and the names of the
+variables that describe the current state of the line read so far.
+
+ The calling sequence for a command 'foo' looks like
+
+ int foo (int count, int key)
+
+where COUNT is the numeric argument (or 1 if defaulted) and KEY is the
+key that invoked this function.
+
+ It is completely up to the function as to what should be done with
+the numeric argument. Some functions use it as a repeat count, some as
+a flag, and others to choose alternate behavior (refreshing the current
+line as opposed to refreshing the screen, for example). Some choose to
+ignore it. In general, if a function uses the numeric argument as a
+repeat count, it should be able to do something useful with both
+negative and positive arguments. At the very least, it should be aware
+that it can be passed a negative argument.
+
+ A command function should return 0 if its action completes
+successfully, and a value greater than zero if some error occurs. This
+is the convention obeyed by all of the builtin Readline bindable command
+functions.
+

+
+2.3 Readline Variables
+======================
+
+These variables are available to function writers.
+
+ -- Variable: char * rl_line_buffer
+ This is the line gathered so far. You are welcome to modify the
+ contents of the line, but see *note Allowing Undoing::. The
+ function 'rl_extend_line_buffer' is available to increase the
+ memory allocated to 'rl_line_buffer'.
+
+ -- Variable: int rl_point
+ The offset of the current cursor position in 'rl_line_buffer' (the
+ _point_).
+
+ -- Variable: int rl_end
+ The number of characters present in 'rl_line_buffer'. When
+ 'rl_point' is at the end of the line, 'rl_point' and 'rl_end' are
+ equal.
+
+ -- Variable: int rl_mark
+ The MARK (saved position) in the current line. If set, the mark
+ and point define a _region_.
+
+ -- Variable: int rl_done
+ Setting this to a non-zero value causes Readline to return the
+ current line immediately.
+
+ -- Variable: int rl_num_chars_to_read
+ Setting this to a positive value before calling 'readline()' causes
+ Readline to return after accepting that many characters, rather
+ than reading up to a character bound to 'accept-line'.
+
+ -- Variable: int rl_pending_input
+ Setting this to a value makes it the next keystroke read. This is
+ a way to stuff a single character into the input stream.
+
+ -- Variable: int rl_dispatching
+ Set to a non-zero value if a function is being called from a key
+ binding; zero otherwise. Application functions can test this to
+ discover whether they were called directly or by Readline's
+ dispatching mechanism.
+
+ -- Variable: int rl_erase_empty_line
+ Setting this to a non-zero value causes Readline to completely
+ erase the current line, including any prompt, any time a newline is
+ typed as the only character on an otherwise-empty line. The cursor
+ is moved to the beginning of the newly-blank line.
+
+ -- Variable: char * rl_prompt
+ The prompt Readline uses. This is set from the argument to
+ 'readline()', and should not be assigned to directly. The
+ 'rl_set_prompt()' function (*note Redisplay::) may be used to
+ modify the prompt string after calling 'readline()'.
+
+ -- Variable: char * rl_display_prompt
+ The string displayed as the prompt. This is usually identical to
+ RL_PROMPT, but may be changed temporarily by functions that use the
+ prompt string as a message area, such as incremental search.
+
+ -- Variable: int rl_already_prompted
+ If an application wishes to display the prompt itself, rather than
+ have Readline do it the first time 'readline()' is called, it
+ should set this variable to a non-zero value after displaying the
+ prompt. The prompt must also be passed as the argument to
+ 'readline()' so the redisplay functions can update the display
+ properly. The calling application is responsible for managing the
+ value; Readline never sets it.
+
+ -- Variable: const char * rl_library_version
+ The version number of this revision of the library.
+
+ -- Variable: int rl_readline_version
+ An integer encoding the current version of the library. The
+ encoding is of the form 0xMMMM, where MM is the two-digit major
+ version number, and MM is the two-digit minor version number. For
+ example, for Readline-4.2, 'rl_readline_version' would have the
+ value 0x0402.
+
+ -- Variable: int rl_gnu_readline_p
+ Always set to 1, denoting that this is GNU readline rather than
+ some emulation.
+
+ -- Variable: const char * rl_terminal_name
+ The terminal type, used for initialization. If not set by the
+ application, Readline sets this to the value of the 'TERM'
+ environment variable the first time it is called.
+
+ -- Variable: const char * rl_readline_name
+ This variable is set to a unique name by each application using
+ Readline. The value allows conditional parsing of the inputrc file
+ (*note Conditional Init Constructs::).
+
+ -- Variable: FILE * rl_instream
+ The stdio stream from which Readline reads input. If 'NULL',
+ Readline defaults to STDIN.
+
+ -- Variable: FILE * rl_outstream
+ The stdio stream to which Readline performs output. If 'NULL',
+ Readline defaults to STDOUT.
+
+ -- Variable: int rl_prefer_env_winsize
+ If non-zero, Readline gives values found in the 'LINES' and
+ 'COLUMNS' environment variables greater precedence than values
+ fetched from the kernel when computing the screen dimensions.
+
+ -- Variable: rl_command_func_t * rl_last_func
+ The address of the last command function Readline executed. May be
+ used to test whether or not a function is being executed twice in
+ succession, for example.
+
+ -- Variable: rl_hook_func_t * rl_startup_hook
+ If non-zero, this is the address of a function to call just before
+ 'readline' prints the first prompt.
+
+ -- Variable: rl_hook_func_t * rl_pre_input_hook
+ If non-zero, this is the address of a function to call after the
+ first prompt has been printed and just before 'readline' starts
+ reading input characters.
+
+ -- Variable: rl_hook_func_t * rl_event_hook
+ If non-zero, this is the address of a function to call periodically
+ when Readline is waiting for terminal input. By default, this will
+ be called at most ten times a second if there is no keyboard input.
+
+ -- Variable: rl_getc_func_t * rl_getc_function
+ If non-zero, Readline will call indirectly through this pointer to
+ get a character from the input stream. By default, it is set to
+ 'rl_getc', the default Readline character input function (*note
+ Character Input::). In general, an application that sets
+ RL_GETC_FUNCTION should consider setting RL_INPUT_AVAILABLE_HOOK as
+ well.
+
+ -- Variable: rl_hook_func_t * rl_signal_event_hook
+ If non-zero, this is the address of a function to call if a read
+ system call is interrupted when Readline is reading terminal input.
+
+ -- Variable: rl_hook_func_t * rl_input_available_hook
+ If non-zero, Readline will use this function's return value when it
+ needs to determine whether or not there is available input on the
+ current input source. The default hook checks 'rl_instream'; if an
+ application is using a different input source, it should set the
+ hook appropriately. Readline queries for available input when
+ implementing intra-key-sequence timeouts during input and
+ incremental searches. This may use an application-specific timeout
+ before returning a value; Readline uses the value passed to
+ 'rl_set_keyboard_input_timeout()' or the value of the user-settable
+ KEYSEQ-TIMEOUT variable. This is designed for use by applications
+ using Readline's callback interface (*note Alternate Interface::),
+ which may not use the traditional 'read(2)' and file descriptor
+ interface, or other applications using a different input mechanism.
+ If an application uses an input mechanism or hook that can
+ potentially exceed the value of KEYSEQ-TIMEOUT, it should increase
+ the timeout or set this hook appropriately even when not using the
+ callback interface. In general, an application that sets
+ RL_GETC_FUNCTION should consider setting RL_INPUT_AVAILABLE_HOOK as
+ well.
+
+ -- Variable: rl_voidfunc_t * rl_redisplay_function
+ If non-zero, Readline will call indirectly through this pointer to
+ update the display with the current contents of the editing buffer.
+ By default, it is set to 'rl_redisplay', the default Readline
+ redisplay function (*note Redisplay::).
+
+ -- Variable: rl_vintfunc_t * rl_prep_term_function
+ If non-zero, Readline will call indirectly through this pointer to
+ initialize the terminal. The function takes a single argument, an
+ 'int' flag that says whether or not to use eight-bit characters.
+ By default, this is set to 'rl_prep_terminal' (*note Terminal
+ Management::).
+
+ -- Variable: rl_voidfunc_t * rl_deprep_term_function
+ If non-zero, Readline will call indirectly through this pointer to
+ reset the terminal. This function should undo the effects of
+ 'rl_prep_term_function'. By default, this is set to
+ 'rl_deprep_terminal' (*note Terminal Management::).
+
+ -- Variable: Keymap rl_executing_keymap
+ This variable is set to the keymap (*note Keymaps::) in which the
+ currently executing readline function was found.
+
+ -- Variable: Keymap rl_binding_keymap
+ This variable is set to the keymap (*note Keymaps::) in which the
+ last key binding occurred.
+
+ -- Variable: char * rl_executing_macro
+ This variable is set to the text of any currently-executing macro.
+
+ -- Variable: int rl_executing_key
+ The key that caused the dispatch to the currently-executing
+ Readline function.
+
+ -- Variable: char * rl_executing_keyseq
+ The full key sequence that caused the dispatch to the
+ currently-executing Readline function.
+
+ -- Variable: int rl_key_sequence_length
+ The number of characters in RL_EXECUTING_KEYSEQ.
+
+ -- Variable: int rl_readline_state
+ A variable with bit values that encapsulate the current Readline
+ state. A bit is set with the 'RL_SETSTATE' macro, and unset with
+ the 'RL_UNSETSTATE' macro. Use the 'RL_ISSTATE' macro to test
+ whether a particular state bit is set. Current state bits include:
+
+ 'RL_STATE_NONE'
+ Readline has not yet been called, nor has it begun to
+ initialize.
+ 'RL_STATE_INITIALIZING'
+ Readline is initializing its internal data structures.
+ 'RL_STATE_INITIALIZED'
+ Readline has completed its initialization.
+ 'RL_STATE_TERMPREPPED'
+ Readline has modified the terminal modes to do its own input
+ and redisplay.
+ 'RL_STATE_READCMD'
+ Readline is reading a command from the keyboard.
+ 'RL_STATE_METANEXT'
+ Readline is reading more input after reading the meta-prefix
+ character.
+ 'RL_STATE_DISPATCHING'
+ Readline is dispatching to a command.
+ 'RL_STATE_MOREINPUT'
+ Readline is reading more input while executing an editing
+ command.
+ 'RL_STATE_ISEARCH'
+ Readline is performing an incremental history search.
+ 'RL_STATE_NSEARCH'
+ Readline is performing a non-incremental history search.
+ 'RL_STATE_SEARCH'
+ Readline is searching backward or forward through the history
+ for a string.
+ 'RL_STATE_NUMERICARG'
+ Readline is reading a numeric argument.
+ 'RL_STATE_MACROINPUT'
+ Readline is currently getting its input from a
+ previously-defined keyboard macro.
+ 'RL_STATE_MACRODEF'
+ Readline is currently reading characters defining a keyboard
+ macro.
+ 'RL_STATE_OVERWRITE'
+ Readline is in overwrite mode.
+ 'RL_STATE_COMPLETING'
+ Readline is performing word completion.
+ 'RL_STATE_SIGHANDLER'
+ Readline is currently executing the readline signal handler.
+ 'RL_STATE_UNDOING'
+ Readline is performing an undo.
+ 'RL_STATE_INPUTPENDING'
+ Readline has input pending due to a call to
+ 'rl_execute_next()'.
+ 'RL_STATE_TTYCSAVED'
+ Readline has saved the values of the terminal's special
+ characters.
+ 'RL_STATE_CALLBACK'
+ Readline is currently using the alternate (callback) interface
+ (*note Alternate Interface::).
+ 'RL_STATE_VIMOTION'
+ Readline is reading the argument to a vi-mode "motion"
+ command.
+ 'RL_STATE_MULTIKEY'
+ Readline is reading a multiple-keystroke command.
+ 'RL_STATE_VICMDONCE'
+ Readline has entered vi command (movement) mode at least one
+ time during the current call to 'readline()'.
+ 'RL_STATE_DONE'
+ Readline has read a key sequence bound to 'accept-line' and is
+ about to return the line to the caller.
+
+ -- Variable: int rl_explicit_arg
+ Set to a non-zero value if an explicit numeric argument was
+ specified by the user. Only valid in a bindable command function.
+
+ -- Variable: int rl_numeric_arg
+ Set to the value of any numeric argument explicitly specified by
+ the user before executing the current Readline function. Only
+ valid in a bindable command function.
+
+ -- Variable: int rl_editing_mode
+ Set to a value denoting Readline's current editing mode. A value
+ of 1 means Readline is currently in emacs mode; 0 means that vi

+
+2.4.1 Naming a Function
+-----------------------
+
+The user can dynamically change the bindings of keys while using
+Readline. This is done by representing the function with a descriptive
+name. The user is able to type the descriptive name when referring to
+the function. Thus, in an init file, one might find
+
+ Meta-Rubout:	backward-kill-word
+
+ This binds the keystroke <Meta-Rubout> to the function
+_descriptively_ named 'backward-kill-word'. You, as the programmer,
+should bind the functions you write to descriptive names as well.
+Readline provides a function for doing that:
+
+ -- Function: int rl_add_defun (const char *name, rl_command_func_t
+ *function, int key)
+ Add NAME to the list of named functions. Make FUNCTION be the
+ function that gets called. If KEY is not -1, then bind it to
+ FUNCTION using 'rl_bind_key()'.
+
+ Using this function alone is sufficient for most applications. It is
+the recommended way to add a few functions to the default functions that
+Readline has built in. If you need to do something other than adding a
+function to Readline, you may need to use the underlying functions
+described below.
+
+&#x1f;
+File: readline.info, Node: Keymaps, Next: Binding Keys, Prev: Function Naming, Up: Readline Convenience Functions
+
+2.4.2 Selecting a Keymap
+------------------------
+
+Key bindings take place on a "keymap". The keymap is the association
+between the keys that the user types and the functions that get run.
+You can make your own keymaps, copy existing keymaps, and tell Readline
+which keymap to use.
+
+ -- Function: Keymap rl_make_bare_keymap (void)
+ Returns a new, empty keymap. The space for the keymap is allocated
+ with 'malloc()'; the caller should free it by calling
+ 'rl_free_keymap()' when done.
+
+ -- Function: Keymap rl_copy_keymap (Keymap map)
+ Return a new keymap which is a copy of MAP.
+
+ -- Function: Keymap rl_make_keymap (void)
+ Return a new keymap with the printing characters bound to
+ rl_insert, the lowercase Meta characters bound to run their
+ equivalents, and the Meta digits bound to produce numeric
+ arguments.
+
+ -- Function: void rl_discard_keymap (Keymap keymap)
+ Free the storage associated with the data in KEYMAP. The caller
+ should free KEYMAP.
+
+ -- Function: void rl_free_keymap (Keymap keymap)
+ Free all storage associated with KEYMAP. This calls
+ 'rl_discard_keymap' to free subordindate keymaps and macros.
+
+ -- Function: int rl_empty_keymap (Keymap keymap)
+ Return non-zero if there are no keys bound to functions in KEYMAP;
+ zero if there are any keys bound.
+
+ Readline has several internal keymaps. These functions allow you to
+change which keymap is active.
+
+ -- Function: Keymap rl_get_keymap (void)
+ Returns the currently active keymap.
+
+ -- Function: void rl_set_keymap (Keymap keymap)
+ Makes KEYMAP the currently active keymap.
+
+ -- Function: Keymap rl_get_keymap_by_name (const char *name)
+ Return the keymap matching NAME. NAME is one which would be
+ supplied in a 'set keymap' inputrc line (*note Readline Init
+ File::).
+
+ -- Function: char * rl_get_keymap_name (Keymap keymap)
+ Return the name matching KEYMAP. NAME is one which would be
+ supplied in a 'set keymap' inputrc line (*note Readline Init
+ File::).
+
+ -- Function: int rl_set_keymap_name (const char *name, Keymap keymap)
+ Set the name of KEYMAP. This name will then be "registered" and
+ available for use in a 'set keymap' inputrc directive *note
+ Readline Init File::). The NAME may not be one of Readline's
+ builtin keymap names; you may not add a different name for one of
+ Readline's builtin keymaps. You may replace the name associated
+ with a given keymap by calling this function more than once with
+ the same KEYMAP argument. You may associate a registered NAME with
+ a new keymap by calling this function more than once with the same
+ NAME argument. There is no way to remove a named keymap once the
+ name has been registered. Readline will make a copy of NAME. The
+ return value is greater than zero unless NAME is one of Readline's
+ builtin keymap names or KEYMAP is one of Readline's builtin
+ keymaps.
+
+&#x1f;
+File: readline.info, Node: Binding Keys, Next: Associating Function Names and Bindings, Prev: Keymaps, Up: Readline Convenience Functions
+
+2.4.3 Binding Keys
+------------------
+
+Key sequences are associate with functions through the keymap. Readline
+has several internal keymaps: 'emacs_standard_keymap',
+'emacs_meta_keymap', 'emacs_ctlx_keymap', 'vi_movement_keymap', and
+'vi_insertion_keymap'. 'emacs_standard_keymap' is the default, and the
+examples in this manual assume that.
+
+ Since 'readline()' installs a set of default key bindings the first
+time it is called, there is always the danger that a custom binding
+installed before the first call to 'readline()' will be overridden. An
+alternate mechanism is to install custom key bindings in an
+initialization function assigned to the 'rl_startup_hook' variable
+(*note Readline Variables::).
+
+ These functions manage key bindings.
+
+ -- Function: int rl_bind_key (int key, rl_command_func_t *function)
+ Binds KEY to FUNCTION in the currently active keymap. Returns
+ non-zero in the case of an invalid KEY.
+
+ -- Function: int rl_bind_key_in_map (int key, rl_command_func_t
+ *function, Keymap map)
+ Bind KEY to FUNCTION in MAP. Returns non-zero in the case of an
+ invalid KEY.
+
+ -- Function: int rl_bind_key_if_unbound (int key, rl_command_func_t
+ *function)
+ Binds KEY to FUNCTION if it is not already bound in the currently
+ active keymap. Returns non-zero in the case of an invalid KEY or
+ if KEY is already bound.
+
+ -- Function: int rl_bind_key_if_unbound_in_map (int key,
+ rl_command_func_t *function, Keymap map)
+ Binds KEY to FUNCTION if it is not already bound in MAP. Returns
+ non-zero in the case of an invalid KEY or if KEY is already bound.
+
+ -- Function: int rl_unbind_key (int key)
+ Bind KEY to the null function in the currently active keymap.
+ Returns non-zero in case of error.
+
+ -- Function: int rl_unbind_key_in_map (int key, Keymap map)
+ Bind KEY to the null function in MAP. Returns non-zero in case of
+ error.
+
+ -- Function: int rl_unbind_function_in_map (rl_command_func_t
+ *function, Keymap map)
+ Unbind all keys that execute FUNCTION in MAP.
+
+ -- Function: int rl_unbind_command_in_map (const char *command, Keymap
+ map)
+ Unbind all keys that are bound to COMMAND in MAP.
+
+ -- Function: int rl_bind_keyseq (const char *keyseq, rl_command_func_t
+ *function)
+ Bind the key sequence represented by the string KEYSEQ to the
+ function FUNCTION, beginning in the current keymap. This makes new
+ keymaps as necessary. The return value is non-zero if KEYSEQ is
+ invalid.
+
+ -- Function: int rl_bind_keyseq_in_map (const char *keyseq,
+ rl_command_func_t *function, Keymap map)
+ Bind the key sequence represented by the string KEYSEQ to the
+ function FUNCTION. This makes new keymaps as necessary. Initial
+ bindings are performed in MAP. The return value is non-zero if
+ KEYSEQ is invalid.
+
+ -- Function: int rl_set_key (const char *keyseq, rl_command_func_t
+ *function, Keymap map)
+ Equivalent to 'rl_bind_keyseq_in_map'.
+
+ -- Function: int rl_bind_keyseq_if_unbound (const char *keyseq,
+ rl_command_func_t *function)
+ Binds KEYSEQ to FUNCTION if it is not already bound in the
+ currently active keymap. Returns non-zero in the case of an
+ invalid KEYSEQ or if KEYSEQ is already bound.
+
+ -- Function: int rl_bind_keyseq_if_unbound_in_map (const char *keyseq,
+ rl_command_func_t *function, Keymap map)
+ Binds KEYSEQ to FUNCTION if it is not already bound in MAP.
+ Returns non-zero in the case of an invalid KEYSEQ or if KEYSEQ is
+ already bound.
+
+ -- Function: int rl_generic_bind (int type, const char *keyseq, char
+ *data, Keymap map)
+ Bind the key sequence represented by the string KEYSEQ to the
+ arbitrary pointer DATA. TYPE says what kind of data is pointed to
+ by DATA; this can be a function ('ISFUNC'), a macro ('ISMACR'), or
+ a keymap ('ISKMAP'). This makes new keymaps as necessary. The
+ initial keymap in which to do bindings is MAP.
+
+ -- Function: int rl_parse_and_bind (char *line)
+ Parse LINE as if it had been read from the 'inputrc' file and
+ perform any key bindings and variable assignments found (*note
+ Readline Init File::).
+
+ -- Function: int rl_read_init_file (const char *filename)
+ Read keybindings and variable assignments from FILENAME (*note
+ Readline Init File::).

+
+2.4.4 Associating Function Names and Bindings
+---------------------------------------------
+
+These functions allow you to find out what keys invoke named functions
+and the functions invoked by a particular key sequence. You may also
+associate a new function name with an arbitrary function.
+
+ -- Function: rl_command_func_t * rl_named_function (const char *name)
+ Return the function with name NAME.
+
+ -- Function: rl_command_func_t * rl_function_of_keyseq (const char
+ *keyseq, Keymap map, int *type)
+ Return the function invoked by KEYSEQ in keymap MAP. If MAP is
+ 'NULL', the current keymap is used. If TYPE is not 'NULL', the
+ type of the object is returned in the 'int' variable it points to
+ (one of 'ISFUNC', 'ISKMAP', or 'ISMACR'). It takes a "translated"
+ key sequence and should not be used if the key sequence can include
+ NUL.
+
+ -- Function: rl_command_func_t * rl_function_of_keyseq_len (const char
+ *keyseq, size_t len, Keymap map, int *type)
+ Return the function invoked by KEYSEQ of length LEN in keymap MAP.
+ Equivalent to 'rl_function_of_keyseq' with the addition of the LEN
+ parameter. It takes a "translated" key sequence and should be used
+ if the key sequence can include NUL.
+
+ -- Function: char ** rl_invoking_keyseqs (rl_command_func_t *function)
+ Return an array of strings representing the key sequences used to
+ invoke FUNCTION in the current keymap.

+2.4.5 Allowing Undoing
+----------------------
+
+Supporting the undo command is a painless thing, and makes your
+functions much more useful. It is certainly easy to try something if
+you know you can undo it.
+
+ If your function simply inserts text once, or deletes text once, and
+uses 'rl_insert_text()' or 'rl_delete_text()' to do it, then undoing is
+already done for you automatically.
+
+ If you do multiple insertions or multiple deletions, or any
+combination of these operations, you should group them together into one
+operation. This is done with 'rl_begin_undo_group()' and
+'rl_end_undo_group()'.
+
+ The types of events that can be undone are:
+
+ enum undo_code { UNDO_DELETE, UNDO_INSERT, UNDO_BEGIN, UNDO_END };
+
+ Notice that 'UNDO_DELETE' means to insert some text, and
+'UNDO_INSERT' means to delete some text. That is, the undo code tells
+what to undo, not how to undo it. 'UNDO_BEGIN' and 'UNDO_END' are tags
+added by 'rl_begin_undo_group()' and 'rl_end_undo_group()'.
+
+ -- Function: int rl_begin_undo_group (void)
+ Begins saving undo information in a group construct. The undo
+ information usually comes from calls to 'rl_insert_text()' and
+ 'rl_delete_text()', but could be the result of calls to
+ 'rl_add_undo()'.
+
+ -- Function: int rl_end_undo_group (void)
+ Closes the current undo group started with 'rl_begin_undo_group
+ ()'. There should be one call to 'rl_end_undo_group()' for each
+ call to 'rl_begin_undo_group()'.
+
+ -- Function: void rl_add_undo (enum undo_code what, int start, int end,
+ char *text)
+ Remember how to undo an event (according to WHAT). The affected
+ text runs from START to END, and encompasses TEXT.
+
+ -- Function: void rl_free_undo_list (void)
+ Free the existing undo list.
+
+ -- Function: int rl_do_undo (void)
+ Undo the first thing on the undo list. Returns '0' if there was
+ nothing to undo, non-zero if something was undone.
+
+ Finally, if you neither insert nor delete text, but directly modify
+the existing text (e.g., change its case), call 'rl_modifying()' once,
+just before you modify the text. You must supply the indices of the
+text range that you are going to modify.
+
+ -- Function: int rl_modifying (int start, int end)
+ Tell Readline to save the text between START and END as a single
+ undo unit. It is assumed that you will subsequently modify that
+ text.

+
+2.4.6 Redisplay
+---------------
+
+ -- Function: void rl_redisplay (void)
+ Change what's displayed on the screen to reflect the current
+ contents of 'rl_line_buffer'.
+
+ -- Function: int rl_forced_update_display (void)
+ Force the line to be updated and redisplayed, whether or not
+ Readline thinks the screen display is correct.
+
+ -- Function: int rl_on_new_line (void)
+ Tell the update functions that we have moved onto a new (empty)
+ line, usually after outputting a newline.
+
+ -- Function: int rl_on_new_line_with_prompt (void)
+ Tell the update functions that we have moved onto a new line, with
+ RL_PROMPT already displayed. This could be used by applications
+ that want to output the prompt string themselves, but still need
+ Readline to know the prompt string length for redisplay. It should
+ be used after setting RL_ALREADY_PROMPTED.
+
+ -- Function: int rl_clear_visible_line (void)
+ Clear the screen lines corresponding to the current line's
+ contents.
+
+ -- Function: int rl_reset_line_state (void)
+ Reset the display state to a clean state and redisplay the current
+ line starting on a new line.
+
+ -- Function: int rl_crlf (void)
+ Move the cursor to the start of the next screen line.
+
+ -- Function: int rl_show_char (int c)
+ Display character C on 'rl_outstream'. If Readline has not been
+ set to display meta characters directly, this will convert meta
+ characters to a meta-prefixed key sequence. This is intended for
+ use by applications which wish to do their own redisplay.
+
+ -- Function: int rl_message (const char *, ...)
+ The arguments are a format string as would be supplied to 'printf',
+ possibly containing conversion specifications such as '%d', and any
+ additional arguments necessary to satisfy the conversion
+ specifications. The resulting string is displayed in the "echo
+ area". The echo area is also used to display numeric arguments and
+ search strings. You should call 'rl_save_prompt' to save the
+ prompt information before calling this function.
+
+ -- Function: int rl_clear_message (void)
+ Clear the message in the echo area. If the prompt was saved with a
+ call to 'rl_save_prompt' before the last call to 'rl_message', call
+ 'rl_restore_prompt' before calling this function.
+
+ -- Function: void rl_save_prompt (void)
+ Save the local Readline prompt display state in preparation for
+ displaying a new message in the message area with 'rl_message()'.
+
+ -- Function: void rl_restore_prompt (void)
+ Restore the local Readline prompt display state saved by the most
+ recent call to 'rl_save_prompt'. if 'rl_save_prompt' was called to
+ save the prompt before a call to 'rl_message', this function should
+ be called before the corresponding call to 'rl_clear_message'.
+
+ -- Function: int rl_expand_prompt (char *prompt)
+ Expand any special character sequences in PROMPT and set up the
+ local Readline prompt redisplay variables. This function is called
+ by 'readline()'. It may also be called to expand the primary
+ prompt if the 'rl_on_new_line_with_prompt()' function or
+ 'rl_already_prompted' variable is used. It returns the number of
+ visible characters on the last line of the (possibly multi-line)
+ prompt. Applications may indicate that the prompt contains
+ characters that take up no physical screen space when displayed by
+ bracketing a sequence of such characters with the special markers
+ 'RL_PROMPT_START_IGNORE' and 'RL_PROMPT_END_IGNORE' (declared in
+ 'readline.h'). This may be used to embed terminal-specific escape
+ sequences in prompts.
+
+ -- Function: int rl_set_prompt (const char *prompt)
+ Make Readline use PROMPT for subsequent redisplay. This calls
+ 'rl_expand_prompt()' to expand the prompt and sets 'rl_prompt' to
+ the result.

+ -- Function: int rl_insert_text (const char *text)
+ Insert TEXT into the line at the current cursor position. Returns
+ the number of characters inserted.
+
+ -- Function: int rl_delete_text (int start, int end)
+ Delete the text between START and END in the current line. Returns
+ the number of characters deleted.
+
+ -- Function: char * rl_copy_text (int start, int end)
+ Return a copy of the text between START and END in the current
+ line.
+
+ -- Function: int rl_kill_text (int start, int end)
+ Copy the text between START and END in the current line to the kill
+ ring, appending or prepending to the last kill if the last command
+ was a kill command. The text is deleted. If START is less than
+ END, the text is appended, otherwise prepended. If the last
+ command was not a kill, a new kill ring slot is used.
+
+ -- Function: int rl_push_macro_input (char *macro)
+ Cause MACRO to be inserted into the line, as if it had been invoked
+ by a key bound to a macro. Not especially useful; use
+ 'rl_insert_text()' instead.

+
+2.4.8 Character Input
+---------------------
+
+ -- Function: int rl_read_key (void)
+ Return the next character available from Readline's current input
+ stream. This handles input inserted into the input stream via
+ RL_PENDING_INPUT (*note Readline Variables::) and
+ 'rl_stuff_char()', macros, and characters read from the keyboard.
+ While waiting for input, this function will call any function
+ assigned to the 'rl_event_hook' variable.
+
+ -- Function: int rl_getc (FILE *stream)
+ Return the next character available from STREAM, which is assumed
+ to be the keyboard.
+
+ -- Function: int rl_stuff_char (int c)
+ Insert C into the Readline input stream. It will be "read" before
+ Readline attempts to read characters from the terminal with
+ 'rl_read_key()'. Up to 512 characters may be pushed back.
+ 'rl_stuff_char' returns 1 if the character was successfully
+ inserted; 0 otherwise.
+
+ -- Function: int rl_execute_next (int c)
+ Make C be the next command to be executed when 'rl_read_key()' is
+ called. This sets RL_PENDING_INPUT.
+
+ -- Function: int rl_clear_pending_input (void)
+ Unset RL_PENDING_INPUT, effectively negating the effect of any
+ previous call to 'rl_execute_next()'. This works only if the
+ pending input has not already been read with 'rl_read_key()'.
+
+ -- Function: int rl_set_keyboard_input_timeout (int u)
+ While waiting for keyboard input in 'rl_read_key()', Readline will
+ wait for U microseconds for input before calling any function
+ assigned to 'rl_event_hook'. U must be greater than or equal to
+ zero (a zero-length timeout is equivalent to a poll). The default
+ waiting period is one-tenth of a second. Returns the old timeout
+ value.

+-------------------------
+
+ -- Function: void rl_prep_terminal (int meta_flag)
+ Modify the terminal settings for Readline's use, so 'readline()'
+ can read a single character at a time from the keyboard. The
+ META_FLAG argument should be non-zero if Readline should read
+ eight-bit input.
+
+ -- Function: void rl_deprep_terminal (void)
+ Undo the effects of 'rl_prep_terminal()', leaving the terminal in
+ the state in which it was before the most recent call to
+ 'rl_prep_terminal()'.
+
+ -- Function: void rl_tty_set_default_bindings (Keymap kmap)
+ Read the operating system's terminal editing characters (as would
+ be displayed by 'stty') to their Readline equivalents. The
+ bindings are performed in KMAP.
+
+ -- Function: void rl_tty_unset_default_bindings (Keymap kmap)
+ Reset the bindings manipulated by 'rl_tty_set_default_bindings' so
+ that the terminal editing characters are bound to 'rl_insert'. The
+ bindings are performed in KMAP.
+
+ -- Function: int rl_tty_set_echoing (int value)
+ Set Readline's idea of whether or not it is echoing output to its
+ output stream (RL_OUTSTREAM). If VALUE is 0, Readline does not
+ display output to RL_OUTSTREAM; any other value enables output.
+ The initial value is set when Readline initializes the terminal
+ settings. This function returns the previous value.
+
+ -- Function: int rl_reset_terminal (const char *terminal_name)
+ Reinitialize Readline's idea of the terminal settings using
+ TERMINAL_NAME as the terminal type (e.g., 'vt100'). If
+ TERMINAL_NAME is 'NULL', the value of the 'TERM' environment
+ variable is used.

+2.4.10 Utility Functions
+------------------------
+
+ -- Function: int rl_save_state (struct readline_state *sp)
+ Save a snapshot of Readline's internal state to SP. The contents
+ of the READLINE_STATE structure are documented in 'readline.h'.
+ The caller is responsible for allocating the structure.
+
+ -- Function: int rl_restore_state (struct readline_state *sp)
+ Restore Readline's internal state to that stored in SP, which must
+ have been saved by a call to 'rl_save_state'. The contents of the
+ READLINE_STATE structure are documented in 'readline.h'. The
+ caller is responsible for freeing the structure.
+
+ -- Function: void rl_free (void *mem)
+ Deallocate the memory pointed to by MEM. MEM must have been
+ allocated by 'malloc'.
+
+ -- Function: void rl_replace_line (const char *text, int clear_undo)
+ Replace the contents of 'rl_line_buffer' with TEXT. The point and

+ undo list associated with the current line is cleared.
+
+ -- Function: void rl_extend_line_buffer (int len)
+ Ensure that 'rl_line_buffer' has enough space to hold LEN
+ characters, possibly reallocating it if necessary.
+
+ -- Function: int rl_initialize (void)
+ Initialize or re-initialize Readline's internal state. It's not
+ strictly necessary to call this; 'readline()' calls it before
+ reading any input.
+
+ -- Function: int rl_ding (void)
+ Ring the terminal bell, obeying the setting of 'bell-style'.
+
+ -- Function: int rl_alphabetic (int c)
+ Return 1 if C is an alphabetic character.
+
+ -- Function: void rl_display_match_list (char **matches, int len, int
+ max)
+ A convenience function for displaying a list of strings in columnar
+ format on Readline's output stream. 'matches' is the list of
+ strings, in argv format, such as a list of completion matches.
+ 'len' is the number of strings in 'matches', and 'max' is the
+ length of the longest string in 'matches'. This function uses the
+ setting of 'print-completions-horizontally' to select how the
+ matches are displayed (*note Readline Init File Syntax::). When
+ displaying completions, this function sets the number of columns
+ used for display to the value of 'completion-display-width', the
+ value of the environment variable 'COLUMNS', or the screen width,
+ in that order.
+
+ The following are implemented as macros, defined in 'chardefs.h'.
+Applications should refrain from using them.
+
+ -- Function: int _rl_uppercase_p (int c)
+ Return 1 if C is an uppercase alphabetic character.
+
+ -- Function: int _rl_lowercase_p (int c)
+ Return 1 if C is a lowercase alphabetic character.
+
+ -- Function: int _rl_digit_p (int c)
+ Return 1 if C is a numeric character.
+
+ -- Function: int _rl_to_upper (int c)
+ If C is a lowercase alphabetic character, return the corresponding
+ uppercase character.
+
+ -- Function: int _rl_to_lower (int c)
+ If C is an uppercase alphabetic character, return the corresponding
+ lowercase character.
+
+ -- Function: int _rl_digit_value (int c)

+------------------------------
+
+ -- Function: int rl_macro_bind (const char *keyseq, const char *macro,

+ will be inserted into the line. This function is deprecated; use
+ 'rl_generic_bind()' instead.
+
+ -- Function: void rl_macro_dumper (int readable)
+ Print the key sequences bound to macros and their values, using the
+ current keymap, to 'rl_outstream'. If READABLE is non-zero, the
+ list is formatted in such a way that it can be made part of an
+ 'inputrc' file and re-read.
+
+ -- Function: int rl_variable_bind (const char *variable, const char
+ *value)
+ Make the Readline variable VARIABLE have VALUE. This behaves as if
+ the readline command 'set VARIABLE VALUE' had been executed in an
+ 'inputrc' file (*note Readline Init File Syntax::).
+
+ -- Function: char * rl_variable_value (const char *variable)
+ Return a string representing the value of the Readline variable
+ VARIABLE. For boolean variables, this string is either 'on' or
+ 'off'.
+
+ -- Function: void rl_variable_dumper (int readable)
+ Print the readline variable names and their current values to

+ re-read.
+
+ -- Function: int rl_set_paren_blink_timeout (int u)
+ Set the time interval (in microseconds) that Readline waits when
+ showing a balancing character when 'blink-matching-paren' has been
+ enabled.
+
+ -- Function: char * rl_get_termcap (const char *cap)
+ Retrieve the string value of the termcap capability CAP. Readline
+ fetches the termcap entry for the current terminal name and uses
+ those capabilities to move around the screen line and perform other
+ terminal-specific operations, like erasing a line. Readline does
+ not use all of a terminal's capabilities, and this function will
+ return values for only those capabilities Readline uses.
+
+ -- Function: void rl_clear_history (void)
+ Clear the history list by deleting all of the entries, in the same
+ manner as the History library's 'clear_history()' function. This
+ differs from 'clear_history' because it frees private data Readline
+ saves in the history list.
+
+ -- Function: void rl_activate_mark (void)
+ Enable an _active_ mark. When this is enabled, the text between
+ point and mark (the REGION) is displayed in the terminal's standout
+ mode (a FACE). This is called by various readline functions that
+ set the mark and insert text, and is available for applications to
+ call.
+
+ -- Function: void rl_deactivate_mark (void)
+ Turn off the active mark.
+
+ -- Function: void rl_keep_mark_active (void)
+ Indicate that the mark should remain active when the current
+ readline function completes and after redisplay occurs. In most
+ cases, the mark remains active for only the duration of a single
+ bindable readline function.
+
+ -- Function: int rl_mark_active_p (void)
+ Return a non-zero value if the mark is currently active; zero

+
+2.4.12 Alternate Interface
+--------------------------
+
+An alternate interface is available to plain 'readline()'. Some
+applications need to interleave keyboard I/O with file, device, or
+window system I/O, typically by using a main loop to 'select()' on
+various file descriptors. To accommodate this need, readline can also
+be invoked as a 'callback' function from an event loop. There are
+functions available to make this easy.
+
+ -- Function: void rl_callback_handler_install (const char *prompt,
+ rl_vcpfunc_t *lhandler)
+ Set up the terminal for readline I/O and display the initial
+ expanded value of PROMPT. Save the value of LHANDLER to use as a
+ handler function to call when a complete line of input has been
+ entered. The handler function receives the text of the line as an
+ argument. As with 'readline()', the handler function should 'free'
+ the line when it it finished with it.
+
+ -- Function: void rl_callback_read_char (void)
+ Whenever an application determines that keyboard input is
+ available, it should call 'rl_callback_read_char()', which will
+ read the next character from the current input source. If that
+ character completes the line, 'rl_callback_read_char' will invoke
+ the LHANDLER function installed by 'rl_callback_handler_install' to
+ process the line. Before calling the LHANDLER function, the
+ terminal settings are reset to the values they had before calling
+ 'rl_callback_handler_install'. If the LHANDLER function returns,
+ and the line handler remains installed, the terminal settings are
+ modified for Readline's use again. 'EOF' is indicated by calling
+ LHANDLER with a 'NULL' line.
+
+ -- Function: void rl_callback_sigcleanup (void)
+ Clean up any internal state the callback interface uses to maintain
+ state between calls to rl_callback_read_char (e.g., the state of
+ any active incremental searches). This is intended to be used by
+ applications that wish to perform their own signal handling;
+ Readline's internal signal handler calls this when appropriate.
+
+ -- Function: void rl_callback_handler_remove (void)
+ Restore the terminal to its initial state and remove the line
+ handler. You may call this function from within a callback as well
+ as independently. If the LHANDLER installed by
+ 'rl_callback_handler_install' does not exit the program, either
+ this function or the function referred to by the value of
+ 'rl_deprep_term_function' should be called before the program exits
+ to reset the terminal settings.

+
+2.5 Readline Signal Handling
+============================
+
+Signals are asynchronous events sent to a process by the Unix kernel,
+sometimes on behalf of another process. They are intended to indicate
+exceptional events, like a user pressing the interrupt key on his
+terminal, or a network connection being broken. There is a class of
+signals that can be sent to the process currently reading input from the
+keyboard. Since Readline changes the terminal attributes when it is
+called, it needs to perform special processing when such a signal is
+received in order to restore the terminal to a sane state, or provide
+application writers with functions to do so manually.
+
+ Readline contains an internal signal handler that is installed for a
+number of signals ('SIGINT', 'SIGQUIT', 'SIGTERM', 'SIGHUP', 'SIGALRM',
+'SIGTSTP', 'SIGTTIN', and 'SIGTTOU'). When one of these signals is
+received, the signal handler will reset the terminal attributes to those
+that were in effect before 'readline()' was called, reset the signal
+handling to what it was before 'readline()' was called, and resend the
+signal to the calling application. If and when the calling
+application's signal handler returns, Readline will reinitialize the
+terminal and continue to accept input. When a 'SIGINT' is received, the
+Readline signal handler performs some additional work, which will cause
+any partially-entered line to be aborted (see the description of
+'rl_free_line_state()' below).
+
+ There is an additional Readline signal handler, for 'SIGWINCH', which
+the kernel sends to a process whenever the terminal's size changes (for
+example, if a user resizes an 'xterm'). The Readline 'SIGWINCH' handler
+updates Readline's internal screen size information, and then calls any
+'SIGWINCH' signal handler the calling application has installed.
+Readline calls the application's 'SIGWINCH' signal handler without
+resetting the terminal to its original state. If the application's
+signal handler does more than update its idea of the terminal size and
+return (for example, a 'longjmp' back to a main processing loop), it
+_must_ call 'rl_cleanup_after_signal()' (described below), to restore
+the terminal state.
+
+ When an application is using the callback interface (*note Alternate
+Interface::), Readline installs signal handlers only for the duration of
+the call to 'rl_callback_read_char'. Applications using the callback
+interface should be prepared to clean up Readline's state if they wish
+to handle the signal before the line handler completes and restores the
+terminal state.
+
+ If an application using the callback interface wishes to have
+Readline install its signal handlers at the time the application calls
+'rl_callback_handler_install' and remove them only when a complete line
+of input has been read, it should set the
+'rl_persistent_signal_handlers' variable to a non-zero value. This
+allows an application to defer all of the handling of the signals
+Readline catches to Readline. Applications should use this variable
+with care; it can result in Readline catching signals and not acting on
+them (or allowing the application to react to them) until the
+application calls 'rl_callback_read_char'. This can result in an
+application becoming less responsive to keyboard signals like SIGINT. If
+an application does not want or need to perform any signal handling, or
+does not need to do any processing between calls to
+'rl_callback_read_char', setting this variable may be desirable.
+
+ Readline provides two variables that allow application writers to
+control whether or not it will catch certain signals and act on them
+when they are received. It is important that applications change the
+values of these variables only when calling 'readline()', not in a
+signal handler, so Readline's internal signal state is not corrupted.
+
+ -- Variable: int rl_catch_signals
+ If this variable is non-zero, Readline will install signal handlers
+ for 'SIGINT', 'SIGQUIT', 'SIGTERM', 'SIGHUP', 'SIGALRM', 'SIGTSTP',
+ 'SIGTTIN', and 'SIGTTOU'.
+
+ The default value of 'rl_catch_signals' is 1.
+
+ -- Variable: int rl_catch_sigwinch
+ If this variable is set to a non-zero value, Readline will install
+ a signal handler for 'SIGWINCH'.
+
+ The default value of 'rl_catch_sigwinch' is 1.
+
+ -- Variable: int rl_persistent_signal_handlers
+ If an application using the callback interface wishes Readline's
+ signal handlers to be installed and active during the set of calls
+ to 'rl_callback_read_char' that constitutes an entire single line,
+ it should set this variable to a non-zero value.
+
+ The default value of 'rl_persistent_signal_handlers' is 0.
+
+ -- Variable: int rl_change_environment
+ If this variable is set to a non-zero value, and Readline is
+ handling 'SIGWINCH', Readline will modify the LINES and COLUMNS
+ environment variables upon receipt of a 'SIGWINCH'
+
+ The default value of 'rl_change_environment' is 1.
+
+ If an application does not wish to have Readline catch any signals,
+or to handle signals other than those Readline catches ('SIGHUP', for
+example), Readline provides convenience functions to do the necessary
+terminal and internal state cleanup upon receipt of a signal.
+
+ -- Function: int rl_pending_signal (void)
+ Return the signal number of the most recent signal Readline
+ received but has not yet handled, or 0 if there is no pending
+ signal.
+
+ -- Function: void rl_cleanup_after_signal (void)
+ This function will reset the state of the terminal to what it was
+ before 'readline()' was called, and remove the Readline signal
+ handlers for all signals, depending on the values of
+ 'rl_catch_signals' and 'rl_catch_sigwinch'.
+
+ -- Function: void rl_free_line_state (void)
+ This will free any partial state associated with the current input
+ line (undo information, any partial history entry, any
+ partially-entered keyboard macro, and any partially-entered numeric
+ argument). This should be called before
+ 'rl_cleanup_after_signal()'. The Readline signal handler for
+ 'SIGINT' calls this to abort the current input line.
+
+ -- Function: void rl_reset_after_signal (void)
+ This will reinitialize the terminal and reinstall any Readline
+ signal handlers, depending on the values of 'rl_catch_signals' and
+ 'rl_catch_sigwinch'.
+
+ If an application wants to force Readline to handle any signals that
+have arrived while it has been executing, 'rl_check_signals()' will call
+Readline's internal signal handler if there are any pending signals.
+This is primarily intended for those applications that use a custom
+'rl_getc_function' (*note Readline Variables::) and wish to handle
+signals received while waiting for input.
+
+ -- Function: void rl_check_signals (void)
+ If there are any pending signals, call Readline's internal signal
+ handling functions to process them. 'rl_pending_signal()' can be
+ used independently to determine whether or not there are any
+ pending signals.
+
+ If an application does not wish Readline to catch 'SIGWINCH', it may
+call 'rl_resize_terminal()' or 'rl_set_screen_size()' to force Readline
+to update its idea of the terminal size when it receives a 'SIGWINCH'.
+
+ -- Function: void rl_echo_signal_char (int sig)
+ If an application wishes to install its own signal handlers, but
+ still have readline display characters that generate signals,
+ calling this function with SIG set to 'SIGINT', 'SIGQUIT', or
+ 'SIGTSTP' will display the character generating that signal.
+
+ -- Function: void rl_resize_terminal (void)
+ Update Readline's internal screen size by reading values from the
+ kernel.
+
+ -- Function: void rl_set_screen_size (int rows, int cols)
+ Set Readline's idea of the terminal size to ROWS rows and COLS
+ columns. If either ROWS or COLUMNS is less than or equal to 0,
+ Readline's idea of that terminal dimension is unchanged. This is
+ intended to tell Readline the physical dimensions of the terminal,
+ and is used internally to calculate the maximum number of
+ characters that may appear on a single line and on the screen.
+
+ If an application does not want to install a 'SIGWINCH' handler, but
+is still interested in the screen dimensions, it may query Readline's
+idea of the screen size.
+
+ -- Function: void rl_get_screen_size (int *rows, int *cols)
+ Return Readline's idea of the terminal's size in the variables
+ pointed to by the arguments.
+
+ -- Function: void rl_reset_screen_size (void)
+ Cause Readline to reobtain the screen size and recalculate its
+ dimensions.
+
+ The following functions install and remove Readline's signal
+handlers.
+
+ -- Function: int rl_set_signals (void)
+ Install Readline's signal handler for 'SIGINT', 'SIGQUIT',
+ 'SIGTERM', 'SIGHUP', 'SIGALRM', 'SIGTSTP', 'SIGTTIN', 'SIGTTOU',
+ and 'SIGWINCH', depending on the values of 'rl_catch_signals' and
+ 'rl_catch_sigwinch'.
+
+ -- Function: int rl_clear_signals (void)
+ Remove all of the Readline signal handlers installed by
+ 'rl_set_signals()'.

+
+2.6 Custom Completers
+=====================
+
+Typically, a program that reads commands from the user has a way of
+disambiguating commands and data. If your program is one of these, then
+it can provide completion for commands, data, or both. The following
+sections describe how your program and Readline cooperate to provide
+this service.
+
+* Menu:
+
+* How Completing Works::	The logic used to do completion.
+* Completion Functions::	Functions provided by Readline.
+* Completion Variables::	Variables which control completion.
+* A Short Completion Example::	An example of writing completer subroutines.
+
+&#x1f;
+File: readline.info, Node: How Completing Works, Next: Completion Functions, Up: Custom Completers
+
+2.6.1 How Completing Works
+--------------------------
+
+In order to complete some text, the full list of possible completions
+must be available. That is, it is not possible to accurately expand a
+partial word without knowing all of the possible words which make sense
+in that context. The Readline library provides the user interface to
+completion, and two of the most common completion functions: filename
+and username. For completing other types of text, you must write your
+own completion function. This section describes exactly what such
+functions must do, and provides an example.
+
+ There are three major functions used to perform completion:
+
+ 1. The user-interface function 'rl_complete()'. This function is
+ called with the same arguments as other bindable Readline
+ functions: COUNT and INVOKING_KEY. It isolates the word to be
+ completed and calls 'rl_completion_matches()' to generate a list of
+ possible completions. It then either lists the possible
+ completions, inserts the possible completions, or actually performs
+ the completion, depending on which behavior is desired.
+
+ 2. The internal function 'rl_completion_matches()' uses an
+ application-supplied "generator" function to generate the list of
+ possible matches, and then returns the array of these matches. The
+ caller should place the address of its generator function in
+ 'rl_completion_entry_function'.
+
+ 3. The generator function is called repeatedly from
+ 'rl_completion_matches()', returning a string each time. The
+ arguments to the generator function are TEXT and STATE. TEXT is
+ the partial word to be completed. STATE is zero the first time the
+ function is called, allowing the generator to perform any necessary
+ initialization, and a positive non-zero integer for each subsequent
+ call. The generator function returns '(char *)NULL' to inform
+ 'rl_completion_matches()' that there are no more possibilities
+ left. Usually the generator function computes the list of possible
+ completions when STATE is zero, and returns them one at a time on
+ subsequent calls. Each string the generator function returns as a
+ match must be allocated with 'malloc()'; Readline frees the strings
+ when it has finished with them. Such a generator function is
+ referred to as an "application-specific completion function".
+
+ -- Function: int rl_complete (int ignore, int invoking_key)
+ Complete the word at or before point. You have supplied the
+ function that does the initial simple matching selection algorithm
+ (see 'rl_completion_matches()'). The default is to do filename
+ completion.
+
+ -- Variable: rl_compentry_func_t * rl_completion_entry_function
+ This is a pointer to the generator function for
+ 'rl_completion_matches()'. If the value of
+ 'rl_completion_entry_function' is 'NULL' then the default filename
+ generator function, 'rl_filename_completion_function()', is used.
+ An "application-specific completion function" is a function whose
+ address is assigned to 'rl_completion_entry_function' and whose
+ return values are used to generate possible completions.
+

+
+2.6.2 Completion Functions
+--------------------------
+
+Here is the complete list of callable completion functions present in
+Readline.
+
+ -- Function: int rl_complete_internal (int what_to_do)
+ Complete the word at or before point. WHAT_TO_DO says what to do
+ with the completion. A value of '?' means list the possible
+ completions. 'TAB' means do standard completion. '*' means insert
+ all of the possible completions. '!' means to display all of the
+ possible completions, if there is more than one, as well as
+ performing partial completion. '@' is similar to '!', but possible
+ completions are not listed if the possible completions share a
+ common prefix.
+
+ -- Function: int rl_complete (int ignore, int invoking_key)
+ Complete the word at or before point. You have supplied the
+ function that does the initial simple matching selection algorithm
+ (see 'rl_completion_matches()' and 'rl_completion_entry_function').
+ The default is to do filename completion. This calls
+ 'rl_complete_internal()' with an argument depending on
+ INVOKING_KEY.
+
+ -- Function: int rl_possible_completions (int count, int invoking_key)
+ List the possible completions. See description of 'rl_complete
+ ()'. This calls 'rl_complete_internal()' with an argument of '?'.
+
+ -- Function: int rl_insert_completions (int count, int invoking_key)
+ Insert the list of possible completions into the line, deleting the
+ partially-completed word. See description of 'rl_complete()'.
+ This calls 'rl_complete_internal()' with an argument of '*'.
+
+ -- Function: int rl_completion_mode (rl_command_func_t *cfunc)
+ Returns the appropriate value to pass to 'rl_complete_internal()'
+ depending on whether CFUNC was called twice in succession and the
+ values of the 'show-all-if-ambiguous' and 'show-all-if-unmodified'
+ variables. Application-specific completion functions may use this
+ function to present the same interface as 'rl_complete()'.
+
+ -- Function: char ** rl_completion_matches (const char *text,
+ rl_compentry_func_t *entry_func)
+ Returns an array of strings which is a list of completions for
+ TEXT. If there are no completions, returns 'NULL'. The first
+ entry in the returned array is the substitution for TEXT. The
+ remaining entries are the possible completions. The array is
+ terminated with a 'NULL' pointer.
+
+ ENTRY_FUNC is a function of two args, and returns a 'char *'. The
+ first argument is TEXT. The second is a state argument; it is zero
+ on the first call, and non-zero on subsequent calls. ENTRY_FUNC
+ returns a 'NULL' pointer to the caller when there are no more
+ matches.
+
+ -- Function: char * rl_filename_completion_function (const char *text,
+ int state)
+ A generator function for filename completion in the general case.
+ TEXT is a partial filename. The Bash source is a useful reference
+ for writing application-specific completion functions (the Bash
+ completion functions call this and other Readline functions).
+
+ -- Function: char * rl_username_completion_function (const char *text,
+ int state)
+ A completion generator for usernames. TEXT contains a partial
+ username preceded by a random character (usually '~'). As with all
+ completion generators, STATE is zero on the first call and non-zero
+ for subsequent calls.
+

+
+2.6.3 Completion Variables
+--------------------------
+
+ -- Variable: rl_compentry_func_t * rl_completion_entry_function
+ A pointer to the generator function for 'rl_completion_matches()'.
+ 'NULL' means to use 'rl_filename_completion_function()', the
+ default filename completer.
+
+ -- Variable: rl_completion_func_t * rl_attempted_completion_function
+ A pointer to an alternative function to create matches. The
+ function is called with TEXT, START, and END. START and END are
+ indices in 'rl_line_buffer' defining the boundaries of TEXT, which
+ is a character string. If this function exists and returns 'NULL',
+ or if this variable is set to 'NULL', then 'rl_complete()' will
+ call the value of 'rl_completion_entry_function' to generate
+ matches, otherwise the array of strings returned will be used. If
+ this function sets the 'rl_attempted_completion_over' variable to a
+ non-zero value, Readline will not perform its default completion
+ even if this function returns no matches.
+
+ -- Variable: rl_quote_func_t * rl_filename_quoting_function
+ A pointer to a function that will quote a filename in an
+ application-specific fashion. This is called if filename
+ completion is being attempted and one of the characters in
+ 'rl_filename_quote_characters' appears in a completed filename.
+ The function is called with TEXT, MATCH_TYPE, and QUOTE_POINTER.
+ The TEXT is the filename to be quoted. The MATCH_TYPE is either
+ 'SINGLE_MATCH', if there is only one completion match, or
+ 'MULT_MATCH'. Some functions use this to decide whether or not to
+ insert a closing quote character. The QUOTE_POINTER is a pointer
+ to any opening quote character the user typed. Some functions
+ choose to reset this character.
+
+ -- Variable: rl_dequote_func_t * rl_filename_dequoting_function
+ A pointer to a function that will remove application-specific
+ quoting characters from a filename before completion is attempted,
+ so those characters do not interfere with matching the text against
+ names in the filesystem. It is called with TEXT, the text of the
+ word to be dequoted, and QUOTE_CHAR, which is the quoting character
+ that delimits the filename (usually ''' or '"'). If QUOTE_CHAR is
+ zero, the filename was not in an embedded string.
+
+ -- Variable: rl_linebuf_func_t * rl_char_is_quoted_p
+ A pointer to a function to call that determines whether or not a
+ specific character in the line buffer is quoted, according to
+ whatever quoting mechanism the program calling Readline uses. The
+ function is called with two arguments: TEXT, the text of the line,
+ and INDEX, the index of the character in the line. It is used to
+ decide whether a character found in
+ 'rl_completer_word_break_characters' should be used to break words
+ for the completer.
+
+ -- Variable: rl_compignore_func_t * rl_ignore_some_completions_function
+ This function, if defined, is called by the completer when real
+ filename completion is done, after all the matching names have been
+ generated. It is passed a 'NULL' terminated array of matches. The
+ first element ('matches0') is the maximal substring common to all
+ matches. This function can re-arrange the list of matches as
+ required, but each element deleted from the array must be freed.
+
+ -- Variable: rl_icppfunc_t * rl_directory_completion_hook
+ This function, if defined, is allowed to modify the directory
+ portion of filenames Readline completes. It could be used to
+ expand symbolic links or shell variables in pathnames. It is
+ called with the address of a string (the current directory name) as
+ an argument, and may modify that string. If the string is replaced
+ with a new string, the old value should be freed. Any modified
+ directory name should have a trailing slash. The modified value
+ will be used as part of the completion, replacing the directory
+ portion of the pathname the user typed. At the least, even if no
+ other expansion is performed, this function should remove any quote
+ characters from the directory name, because its result will be
+ passed directly to 'opendir()'.
+
+ The directory completion hook returns an integer that should be
+ non-zero if the function modifies its directory argument. The
+ function should not modify the directory argument if it returns 0.
+
+ -- Variable: rl_icppfunc_t * rl_directory_rewrite_hook;
+ If non-zero, this is the address of a function to call when
+ completing a directory name. This function takes the address of
+ the directory name to be modified as an argument. Unlike
+ 'rl_directory_completion_hook', it only modifies the directory name
+ used in 'opendir', not what is displayed when the possible
+ completions are printed or inserted. It is called before
+ rl_directory_completion_hook. At the least, even if no other
+ expansion is performed, this function should remove any quote
+ characters from the directory name, because its result will be
+ passed directly to 'opendir()'.
+
+ The directory rewrite hook returns an integer that should be
+ non-zero if the function modifies its directory argument. The
+ function should not modify the directory argument if it returns 0.
+
+ -- Variable: rl_icppfunc_t * rl_filename_stat_hook
+ If non-zero, this is the address of a function for the completer to
+ call before deciding which character to append to a completed name.
+ This function modifies its filename name argument, and the modified
+ value is passed to 'stat()' to determine the file's type and
+ characteristics. This function does not need to remove quote
+ characters from the filename.
+
+ The stat hook returns an integer that should be non-zero if the
+ function modifies its directory argument. The function should not
+ modify the directory argument if it returns 0.
+
+ -- Variable: rl_dequote_func_t * rl_filename_rewrite_hook
+ If non-zero, this is the address of a function called when reading
+ directory entries from the filesystem for completion and comparing
+ them to the partial word to be completed. The function should
+ perform any necessary application or system-specific conversion on
+ the filename, such as converting between character sets or
+ converting from a filesystem format to a character input format.
+ The function takes two arguments: FNAME, the filename to be
+ converted, and FNLEN, its length in bytes. It must either return
+ its first argument (if no conversion takes place) or the converted
+ filename in newly-allocated memory. The converted form is used to
+ compare against the word to be completed, and, if it matches, is
+ added to the list of matches. Readline will free the allocated
+ string.
+
+ -- Variable: rl_compdisp_func_t * rl_completion_display_matches_hook
+ If non-zero, then this is the address of a function to call when
+ completing a word would normally display the list of possible
+ matches. This function is called in lieu of Readline displaying
+ the list. It takes three arguments: ('char **'MATCHES, 'int'
+ NUM_MATCHES, 'int' MAX_LENGTH) where MATCHES is the array of
+ matching strings, NUM_MATCHES is the number of strings in that
+ array, and MAX_LENGTH is the length of the longest string in that
+ array. Readline provides a convenience function,
+ 'rl_display_match_list', that takes care of doing the display to
+ Readline's output stream. You may call that function from this
+ hook.
+
+ -- Variable: const char * rl_basic_word_break_characters
+ The basic list of characters that signal a break between words for
+ the completer routine. The default value of this variable is the
+ characters which break words for completion in Bash: '"
+ \t\n\"\\'`@$><=;|&{("'.
+
+ -- Variable: const char * rl_basic_quote_characters
+ A list of quote characters which can cause a word break.
+
+ -- Variable: const char * rl_completer_word_break_characters
+ The list of characters that signal a break between words for
+ 'rl_complete_internal()'. The default list is the value of
+ 'rl_basic_word_break_characters'.
+
+ -- Variable: rl_cpvfunc_t * rl_completion_word_break_hook
+ If non-zero, this is the address of a function to call when
+ Readline is deciding where to separate words for word completion.
+ It should return a character string like
+ 'rl_completer_word_break_characters' to be used to perform the
+ current completion. The function may choose to set
+ 'rl_completer_word_break_characters' itself. If the function
+ returns 'NULL', 'rl_completer_word_break_characters' is used.
+
+ -- Variable: const char * rl_completer_quote_characters
+ A list of characters which can be used to quote a substring of the
+ line. Completion occurs on the entire substring, and within the
+ substring 'rl_completer_word_break_characters' are treated as any
+ other character, unless they also appear within this list.
+
+ -- Variable: const char * rl_filename_quote_characters
+ A list of characters that cause a filename to be quoted by the
+ completer when they appear in a completed filename. The default is
+ the null string.
+
+ -- Variable: const char * rl_special_prefixes
+ The list of characters that are word break characters, but should
+ be left in TEXT when it is passed to the completion function.
+ Programs can use this to help determine what kind of completing to
+ do. For instance, Bash sets this variable to "$@" so that it can
+ complete shell variables and hostnames.
+
+ -- Variable: int rl_completion_query_items
+ Up to this many items will be displayed in response to a
+ possible-completions call. After that, readline asks the user if
+ she is sure she wants to see them all. The default value is 100.
+ A negative value indicates that Readline should never ask the user.
+
+ -- Variable: int rl_completion_append_character
+ When a single completion alternative matches at the end of the
+ command line, this character is appended to the inserted completion
+ text. The default is a space character (' '). Setting this to the
+ null character ('\0') prevents anything being appended
+ automatically. This can be changed in application-specific
+ completion functions to provide the "most sensible word separator
+ character" according to an application-specific command line syntax
+ specification. It is set to the default before any
+ application-specific completion function is called, and may only be
+ changed within such a function.
+
+ -- Variable: int rl_completion_suppress_append
+ If non-zero, RL_COMPLETION_APPEND_CHARACTER is not appended to
+ matches at the end of the command line, as described above. It is
+ set to 0 before any application-specific completion function is
+ called, and may only be changed within such a function.
+
+ -- Variable: int rl_completion_quote_character
+ When Readline is completing quoted text, as delimited by one of the
+ characters in RL_COMPLETER_QUOTE_CHARACTERS, it sets this variable
+ to the quoting character found. This is set before any
+ application-specific completion function is called.
+
+ -- Variable: int rl_completion_suppress_quote
+ If non-zero, Readline does not append a matching quote character
+ when performing completion on a quoted string. It is set to 0
+ before any application-specific completion function is called, and
+ may only be changed within such a function.
+
+ -- Variable: int rl_completion_found_quote
+ When Readline is completing quoted text, it sets this variable to a
+ non-zero value if the word being completed contains or is delimited
+ by any quoting characters, including backslashes. This is set
+ before any application-specific completion function is called.
+
+ -- Variable: int rl_completion_mark_symlink_dirs
+ If non-zero, a slash will be appended to completed filenames that
+ are symbolic links to directory names, subject to the value of the
+ user-settable MARK-DIRECTORIES variable. This variable exists so
+ that application-specific completion functions can override the
+ user's global preference (set via the MARK-SYMLINKED-DIRECTORIES
+ Readline variable) if appropriate. This variable is set to the
+ user's preference before any application-specific completion
+ function is called, so unless that function modifies the value, the
+ user's preferences are honored.
+
+ -- Variable: int rl_ignore_completion_duplicates
+ If non-zero, then duplicates in the matches are removed. The
+ default is 1.
+
+ -- Variable: int rl_filename_completion_desired
+ Non-zero means that the results of the matches are to be treated as
+ filenames. This is _always_ zero when completion is attempted, and
+ can only be changed within an application-specific completion
+ function. If it is set to a non-zero value by such a function,
+ directory names have a slash appended and Readline attempts to
+ quote completed filenames if they contain any characters in
+ 'rl_filename_quote_characters' and 'rl_filename_quoting_desired' is
+ set to a non-zero value.
+
+ -- Variable: int rl_filename_quoting_desired
+ Non-zero means that the results of the matches are to be quoted
+ using double quotes (or an application-specific quoting mechanism)
+ if the completed filename contains any characters in
+ 'rl_filename_quote_chars'. This is _always_ non-zero when
+ completion is attempted, and can only be changed within an
+ application-specific completion function. The quoting is effected
+ via a call to the function pointed to by
+ 'rl_filename_quoting_function'.
+
+ -- Variable: int rl_attempted_completion_over
+ If an application-specific completion function assigned to
+ 'rl_attempted_completion_function' sets this variable to a non-zero
+ value, Readline will not perform its default filename completion
+ even if the application's completion function returns no matches.
+ It should be set only by an application's completion function.
+
+ -- Variable: int rl_sort_completion_matches
+ If an application sets this variable to 0, Readline will not sort
+ the list of completions (which implies that it cannot remove any
+ duplicate completions). The default value is 1, which means that
+ Readline will sort the completions and, depending on the value of
+ 'rl_ignore_completion_duplicates', will attempt to remove duplicate
+ matches.
+
+ -- Variable: int rl_completion_type
+ Set to a character describing the type of completion Readline is
+ currently attempting; see the description of
+ 'rl_complete_internal()' (*note Completion Functions::) for the
+ list of characters. This is set to the appropriate value before
+ any application-specific completion function is called, allowing
+ such functions to present the same interface as 'rl_complete()'.
+
+ -- Variable: int rl_completion_invoking_key
+ Set to the final character in the key sequence that invoked one of
+ the completion functions that call 'rl_complete_internal()'. This
+ is set to the appropriate value before any application-specific
+ completion function is called.
+
+ -- Variable: int rl_inhibit_completion
+ If this variable is non-zero, completion is inhibited. The
+ completion character will be inserted as any other bound to
+ 'self-insert'.

+
+Here is a small application demonstrating the use of the GNU Readline
+library. It is called 'fileman', and the source code resides in
+'examples/fileman.c'. This sample application provides completion of
+command names, line editing features, and access to the history list.

+*****************************************
+
+ Version 1.3, 3 November 2008
+
+ Copyright (C) 2000, 2001, 2002, 2007, 2008 Free Software Foundation, Inc.
+ <http://fsf.org/>
+
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ 0. PREAMBLE
+
+ The purpose of this License is to make a manual, textbook, or other
+ functional and useful document "free" in the sense of freedom: to
+ assure everyone the effective freedom to copy and redistribute it,
+ with or without modifying it, either commercially or
+ noncommercially. Secondarily, this License preserves for the
+ author and publisher a way to get credit for their work, while not
+ being considered responsible for modifications made by others.
+
+ This License is a kind of "copyleft", which means that derivative
+ works of the document must themselves be free in the same sense.
+ It complements the GNU General Public License, which is a copyleft
+ license designed for free software.
+
+ We have designed this License in order to use it for manuals for
+ free software, because free software needs free documentation: a
+ free program should come with manuals providing the same freedoms
+ that the software does. But this License is not limited to
+ software manuals; it can be used for any textual work, regardless
+ of subject matter or whether it is published as a printed book. We
+ recommend this License principally for works whose purpose is
+ instruction or reference.
+
+ 1. APPLICABILITY AND DEFINITIONS
+
+ This License applies to any manual or other work, in any medium,
+ that contains a notice placed by the copyright holder saying it can
+ be distributed under the terms of this License. Such a notice
+ grants a world-wide, royalty-free license, unlimited in duration,
+ to use that work under the conditions stated herein. The
+ "Document", below, refers to any such manual or work. Any member
+ of the public is a licensee, and is addressed as "you". You accept
+ the license if you copy, modify or distribute the work in a way
+ requiring permission under copyright law.
+
+ A "Modified Version" of the Document means any work containing the
+ Document or a portion of it, either copied verbatim, or with
+ modifications and/or translated into another language.
+
+ A "Secondary Section" is a named appendix or a front-matter section
+ of the Document that deals exclusively with the relationship of the
+ publishers or authors of the Document to the Document's overall
+ subject (or to related matters) and contains nothing that could
+ fall directly within that overall subject. (Thus, if the Document
+ is in part a textbook of mathematics, a Secondary Section may not
+ explain any mathematics.) The relationship could be a matter of
+ historical connection with the subject or with related matters, or
+ of legal, commercial, philosophical, ethical or political position
+ regarding them.
+
+ The "Invariant Sections" are certain Secondary Sections whose
+ titles are designated, as being those of Invariant Sections, in the
+ notice that says that the Document is released under this License.
+ If a section does not fit the above definition of Secondary then it
+ is not allowed to be designated as Invariant. The Document may
+ contain zero Invariant Sections. If the Document does not identify
+ any Invariant Sections then there are none.
+
+ The "Cover Texts" are certain short passages of text that are
+ listed, as Front-Cover Texts or Back-Cover Texts, in the notice
+ that says that the Document is released under this License. A
+ Front-Cover Text may be at most 5 words, and a Back-Cover Text may
+ be at most 25 words.
+
+ A "Transparent" copy of the Document means a machine-readable copy,
+ represented in a format whose specification is available to the
+ general public, that is suitable for revising the document
+ straightforwardly with generic text editors or (for images composed
+ of pixels) generic paint programs or (for drawings) some widely
+ available drawing editor, and that is suitable for input to text
+ formatters or for automatic translation to a variety of formats
+ suitable for input to text formatters. A copy made in an otherwise
+ Transparent file format whose markup, or absence of markup, has
+ been arranged to thwart or discourage subsequent modification by
+ readers is not Transparent. An image format is not Transparent if
+ used for any substantial amount of text. A copy that is not
+ "Transparent" is called "Opaque".
+
+ Examples of suitable formats for Transparent copies include plain
+ ASCII without markup, Texinfo input format, LaTeX input format,
+ SGML or XML using a publicly available DTD, and standard-conforming
+ simple HTML, PostScript or PDF designed for human modification.
+ Examples of transparent image formats include PNG, XCF and JPG.
+ Opaque formats include proprietary formats that can be read and
+ edited only by proprietary word processors, SGML or XML for which
+ the DTD and/or processing tools are not generally available, and
+ the machine-generated HTML, PostScript or PDF produced by some word
+ processors for output purposes only.
+
+ The "Title Page" means, for a printed book, the title page itself,
+ plus such following pages as are needed to hold, legibly, the
+ material this License requires to appear in the title page. For
+ works in formats which do not have any title page as such, "Title
+ Page" means the text near the most prominent appearance of the
+ work's title, preceding the beginning of the body of the text.
+
+ The "publisher" means any person or entity that distributes copies
+ of the Document to the public.
+
+ A section "Entitled XYZ" means a named subunit of the Document
+ whose title either is precisely XYZ or contains XYZ in parentheses
+ following text that translates XYZ in another language. (Here XYZ
+ stands for a specific section name mentioned below, such as
+ "Acknowledgements", "Dedications", "Endorsements", or "History".)
+ To "Preserve the Title" of such a section when you modify the
+ Document means that it remains a section "Entitled XYZ" according
+ to this definition.
+
+ The Document may include Warranty Disclaimers next to the notice
+ which states that this License applies to the Document. These
+ Warranty Disclaimers are considered to be included by reference in
+ this License, but only as regards disclaiming warranties: any other
+ implication that these Warranty Disclaimers may have is void and
+ has no effect on the meaning of this License.
+
+ 2. VERBATIM COPYING
+
+ You may copy and distribute the Document in any medium, either
+ commercially or noncommercially, provided that this License, the
+ copyright notices, and the license notice saying this License
+ applies to the Document are reproduced in all copies, and that you
+ add no other conditions whatsoever to those of this License. You
+ may not use technical measures to obstruct or control the reading
+ or further copying of the copies you make or distribute. However,
+ you may accept compensation in exchange for copies. If you
+ distribute a large enough number of copies you must also follow the
+ conditions in section 3.
+
+ You may also lend copies, under the same conditions stated above,
+ and you may publicly display copies.
+
+ 3. COPYING IN QUANTITY
+
+ If you publish printed copies (or copies in media that commonly
+ have printed covers) of the Document, numbering more than 100, and
+ the Document's license notice requires Cover Texts, you must
+ enclose the copies in covers that carry, clearly and legibly, all
+ these Cover Texts: Front-Cover Texts on the front cover, and
+ Back-Cover Texts on the back cover. Both covers must also clearly
+ and legibly identify you as the publisher of these copies. The
+ front cover must present the full title with all words of the title
+ equally prominent and visible. You may add other material on the
+ covers in addition. Copying with changes limited to the covers, as
+ long as they preserve the title of the Document and satisfy these
+ conditions, can be treated as verbatim copying in other respects.
+
+ If the required texts for either cover are too voluminous to fit
+ legibly, you should put the first ones listed (as many as fit
+ reasonably) on the actual cover, and continue the rest onto
+ adjacent pages.
+
+ If you publish or distribute Opaque copies of the Document
+ numbering more than 100, you must either include a machine-readable
+ Transparent copy along with each Opaque copy, or state in or with
+ each Opaque copy a computer-network location from which the general
+ network-using public has access to download using public-standard
+ network protocols a complete Transparent copy of the Document, free
+ of added material. If you use the latter option, you must take
+ reasonably prudent steps, when you begin distribution of Opaque
+ copies in quantity, to ensure that this Transparent copy will
+ remain thus accessible at the stated location until at least one
+ year after the last time you distribute an Opaque copy (directly or
+ through your agents or retailers) of that edition to the public.
+
+ It is requested, but not required, that you contact the authors of
+ the Document well before redistributing any large number of copies,
+ to give them a chance to provide you with an updated version of the
+ Document.
+
+ 4. MODIFICATIONS
+
+ You may copy and distribute a Modified Version of the Document
+ under the conditions of sections 2 and 3 above, provided that you
+ release the Modified Version under precisely this License, with the
+ Modified Version filling the role of the Document, thus licensing
+ distribution and modification of the Modified Version to whoever
+ possesses a copy of it. In addition, you must do these things in
+ the Modified Version:
+
+ A. Use in the Title Page (and on the covers, if any) a title
+ distinct from that of the Document, and from those of previous
+ versions (which should, if there were any, be listed in the
+ History section of the Document). You may use the same title
+ as a previous version if the original publisher of that
+ version gives permission.
+
+ B. List on the Title Page, as authors, one or more persons or
+ entities responsible for authorship of the modifications in
+ the Modified Version, together with at least five of the
+ principal authors of the Document (all of its principal
+ authors, if it has fewer than five), unless they release you
+ from this requirement.
+
+ C. State on the Title page the name of the publisher of the
+ Modified Version, as the publisher.
+
+ D. Preserve all the copyright notices of the Document.
+
+ E. Add an appropriate copyright notice for your modifications
+ adjacent to the other copyright notices.
+
+ F. Include, immediately after the copyright notices, a license
+ notice giving the public permission to use the Modified
+ Version under the terms of this License, in the form shown in
+ the Addendum below.
+
+ G. Preserve in that license notice the full lists of Invariant
+ Sections and required Cover Texts given in the Document's
+ license notice.
+
+ H. Include an unaltered copy of this License.
+
+ I. Preserve the section Entitled "History", Preserve its Title,
+ and add to it an item stating at least the title, year, new
+ authors, and publisher of the Modified Version as given on the
+ Title Page. If there is no section Entitled "History" in the
+ Document, create one stating the title, year, authors, and
+ publisher of the Document as given on its Title Page, then add
+ an item describing the Modified Version as stated in the
+ previous sentence.
+
+ J. Preserve the network location, if any, given in the Document
+ for public access to a Transparent copy of the Document, and
+ likewise the network locations given in the Document for
+ previous versions it was based on. These may be placed in the
+ "History" section. You may omit a network location for a work
+ that was published at least four years before the Document
+ itself, or if the original publisher of the version it refers
+ to gives permission.
+
+ K. For any section Entitled "Acknowledgements" or "Dedications",
+ Preserve the Title of the section, and preserve in the section
+ all the substance and tone of each of the contributor
+ acknowledgements and/or dedications given therein.
+
+ L. Preserve all the Invariant Sections of the Document, unaltered
+ in their text and in their titles. Section numbers or the
+ equivalent are not considered part of the section titles.
+
+ M. Delete any section Entitled "Endorsements". Such a section
+ may not be included in the Modified Version.
+
+ N. Do not retitle any existing section to be Entitled
+ "Endorsements" or to conflict in title with any Invariant
+ Section.
+
+ O. Preserve any Warranty Disclaimers.
+
+ If the Modified Version includes new front-matter sections or
+ appendices that qualify as Secondary Sections and contain no
+ material copied from the Document, you may at your option designate
+ some or all of these sections as invariant. To do this, add their
+ titles to the list of Invariant Sections in the Modified Version's
+ license notice. These titles must be distinct from any other
+ section titles.
+
+ You may add a section Entitled "Endorsements", provided it contains
+ nothing but endorsements of your Modified Version by various
+ parties--for example, statements of peer review or that the text
+ has been approved by an organization as the authoritative
+ definition of a standard.
+
+ You may add a passage of up to five words as a Front-Cover Text,
+ and a passage of up to 25 words as a Back-Cover Text, to the end of
+ the list of Cover Texts in the Modified Version. Only one passage
+ of Front-Cover Text and one of Back-Cover Text may be added by (or
+ through arrangements made by) any one entity. If the Document
+ already includes a cover text for the same cover, previously added
+ by you or by arrangement made by the same entity you are acting on
+ behalf of, you may not add another; but you may replace the old
+ one, on explicit permission from the previous publisher that added
+ the old one.
+
+ The author(s) and publisher(s) of the Document do not by this
+ License give permission to use their names for publicity for or to
+ assert or imply endorsement of any Modified Version.
+
+ 5. COMBINING DOCUMENTS
+
+ You may combine the Document with other documents released under
+ this License, under the terms defined in section 4 above for
+ modified versions, provided that you include in the combination all
+ of the Invariant Sections of all of the original documents,
+ unmodified, and list them all as Invariant Sections of your
+ combined work in its license notice, and that you preserve all
+ their Warranty Disclaimers.
+
+ The combined work need only contain one copy of this License, and
+ multiple identical Invariant Sections may be replaced with a single
+ copy. If there are multiple Invariant Sections with the same name
+ but different contents, make the title of each such section unique
+ by adding at the end of it, in parentheses, the name of the
+ original author or publisher of that section if known, or else a
+ unique number. Make the same adjustment to the section titles in
+ the list of Invariant Sections in the license notice of the
+ combined work.
+
+ In the combination, you must combine any sections Entitled
+ "History" in the various original documents, forming one section
+ Entitled "History"; likewise combine any sections Entitled
+ "Acknowledgements", and any sections Entitled "Dedications". You
+ must delete all sections Entitled "Endorsements."
+
+ 6. COLLECTIONS OF DOCUMENTS
+
+ You may make a collection consisting of the Document and other
+ documents released under this License, and replace the individual
+ copies of this License in the various documents with a single copy
+ that is included in the collection, provided that you follow the
+ rules of this License for verbatim copying of each of the documents
+ in all other respects.
+
+ You may extract a single document from such a collection, and
+ distribute it individually under this License, provided you insert
+ a copy of this License into the extracted document, and follow this
+ License in all other respects regarding verbatim copying of that
+ document.
+
+ 7. AGGREGATION WITH INDEPENDENT WORKS
+
+ A compilation of the Document or its derivatives with other
+ separate and independent documents or works, in or on a volume of a
+ storage or distribution medium, is called an "aggregate" if the
+ copyright resulting from the compilation is not used to limit the
+ legal rights of the compilation's users beyond what the individual
+ works permit. When the Document is included in an aggregate, this
+ License does not apply to the other works in the aggregate which
+ are not themselves derivative works of the Document.
+
+ If the Cover Text requirement of section 3 is applicable to these
+ copies of the Document, then if the Document is less than one half
+ of the entire aggregate, the Document's Cover Texts may be placed
+ on covers that bracket the Document within the aggregate, or the
+ electronic equivalent of covers if the Document is in electronic
+ form. Otherwise they must appear on printed covers that bracket
+ the whole aggregate.
+
+ 8. TRANSLATION
+
+ Translation is considered a kind of modification, so you may
+ distribute translations of the Document under the terms of section
+ 4. Replacing Invariant Sections with translations requires special
+ permission from their copyright holders, but you may include
+ translations of some or all Invariant Sections in addition to the
+ original versions of these Invariant Sections. You may include a
+ translation of this License, and all the license notices in the
+ Document, and any Warranty Disclaimers, provided that you also
+ include the original English version of this License and the
+ original versions of those notices and disclaimers. In case of a
+ disagreement between the translation and the original version of
+ this License or a notice or disclaimer, the original version will
+ prevail.
+
+ If a section in the Document is Entitled "Acknowledgements",
+ "Dedications", or "History", the requirement (section 4) to
+ Preserve its Title (section 1) will typically require changing the
+ actual title.
+
+ 9. TERMINATION
+
+ You may not copy, modify, sublicense, or distribute the Document
+ except as expressly provided under this License. Any attempt
+ otherwise to copy, modify, sublicense, or distribute it is void,
+ and will automatically terminate your rights under this License.
+
+ However, if you cease all violation of this License, then your
+ license from a particular copyright holder is reinstated (a)
+ provisionally, unless and until the copyright holder explicitly and
+ finally terminates your license, and (b) permanently, if the
+ copyright holder fails to notify you of the violation by some
+ reasonable means prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+ reinstated permanently if the copyright holder notifies you of the
+ violation by some reasonable means, this is the first time you have
+ received notice of violation of this License (for any work) from
+ that copyright holder, and you cure the violation prior to 30 days
+ after your receipt of the notice.
+
+ Termination of your rights under this section does not terminate
+ the licenses of parties who have received copies or rights from you
+ under this License. If your rights have been terminated and not
+ permanently reinstated, receipt of a copy of some or all of the
+ same material does not give you any rights to use it.
+
+ 10. FUTURE REVISIONS OF THIS LICENSE
+
+ The Free Software Foundation may publish new, revised versions of
+ the GNU Free Documentation License from time to time. Such new
+ versions will be similar in spirit to the present version, but may
+ differ in detail to address new problems or concerns. See
+ <http://www.gnu.org/copyleft/>.
+
+ Each version of the License is given a distinguishing version
+ number. If the Document specifies that a particular numbered
+ version of this License "or any later version" applies to it, you
+ have the option of following the terms and conditions either of
+ that specified version or of any later version that has been
+ published (not as a draft) by the Free Software Foundation. If the
+ Document does not specify a version number of this License, you may
+ choose any version ever published (not as a draft) by the Free
+ Software Foundation. If the Document specifies that a proxy can
+ decide which future versions of this License can be used, that
+ proxy's public statement of acceptance of a version permanently
+ authorizes you to choose that version for the Document.
+
+ 11. RELICENSING
+
+ "Massive Multiauthor Collaboration Site" (or "MMC Site") means any
+ World Wide Web server that publishes copyrightable works and also
+ provides prominent facilities for anybody to edit those works. A
+ public wiki that anybody can edit is an example of such a server.
+ A "Massive Multiauthor Collaboration" (or "MMC") contained in the
+ site means any set of copyrightable works thus published on the MMC
+ site.
+
+ "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0
+ license published by Creative Commons Corporation, a not-for-profit
+ corporation with a principal place of business in San Francisco,
+ California, as well as future copyleft versions of that license
+ published by that same organization.
+
+ "Incorporate" means to publish or republish a Document, in whole or
+ in part, as part of another Document.
+
+ An MMC is "eligible for relicensing" if it is licensed under this
+ License, and if all works that were first published under this
+ License somewhere other than this MMC, and subsequently
+ incorporated in whole or in part into the MMC, (1) had no cover
+ texts or invariant sections, and (2) were thus incorporated prior
+ to November 1, 2008.
+
+ The operator of an MMC Site may republish an MMC contained in the
+ site under CC-BY-SA on the same site at any time before August 1,
+ 2009, provided the MMC is eligible for relicensing.
+
+ADDENDUM: How to use this License for your documents
+====================================================
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and license
+notices just after the title page:
+
+ Copyright (C) YEAR YOUR NAME.
+ Permission is granted to copy, distribute and/or modify this document
+ under the terms of the GNU Free Documentation License, Version 1.3
+ or any later version published by the Free Software Foundation;
+ with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
+ Texts. A copy of the license is included in the section entitled ``GNU
+ Free Documentation License''.
+
+ If you have Invariant Sections, Front-Cover Texts and Back-Cover
+Texts, replace the "with...Texts." line with this:
+
+ with the Invariant Sections being LIST THEIR TITLES, with
+ the Front-Cover Texts being LIST, and with the Back-Cover Texts
+ being LIST.
+
+ If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+
+ If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of free
+software license, such as the GNU General Public License, to permit
+their use in free software.

+@node Programming with GNU Readline
+@chapter Programming with GNU Readline
+
+This chapter describes the interface between the @sc{gnu} Readline Library and
+other programs. If you are a programmer, and you wish to include the
+features found in @sc{gnu} Readline
+such as completion, line editing, and interactive history manipulation
+in your own programs, this section is for you.
+
+@menu
+* Basic Behavior::	Using the default behavior of Readline.
+* Custom Functions::	Adding your own functions to Readline.
+* Readline Variables::			Variables accessible to custom
+					functions.
+* Readline Convenience Functions::	Functions which Readline supplies to

+* Custom Completers::	Supplanting or supplementing Readline's
+			completion functions.
+@end menu
+
+@node Basic Behavior
+@section Basic Behavior
+
+Many programs provide a command line interface, such as @code{mail},
+@code{ftp}, and @code{sh}. For such programs, the default behaviour of
+Readline is sufficient. This section describes how to use Readline in
+the simplest way possible, perhaps to replace calls in your code to
+@code{gets()} or @code{fgets()}.
+
+@findex readline
+@cindex readline, function
+
+The function @code{readline()} prints a prompt @var{prompt}
+and then reads and returns a single line of text from the user.
+If @var{prompt} is @code{NULL} or the empty string, no prompt is displayed.
+The line @code{readline} returns is allocated with @code{malloc()};
+the caller should @code{free()} the line when it has finished with it.
+The declaration for @code{readline} in ANSI C is
+
+@example
+@code{char *readline (const char *@var{prompt});}
+@end example
+
+@noindent
+So, one might say
+@example
+@code{char *line = readline ("Enter a line: ");}
+@end example
+@noindent
+in order to read a line of text from the user.
+The line returned has the final newline removed, so only the
+text remains.
+
+If @code{readline} encounters an @code{EOF} while reading the line, and the
+line is empty at that point, then @code{(char *)NULL} is returned.
+Otherwise, the line is ended just as if a newline had been typed.
+
+Readline performs some expansion on the @var{prompt} before it is
+displayed on the screen. See the description of @code{rl_expand_prompt}
+(@pxref{Redisplay}) for additional details, especially if @var{prompt}
+will contain characters that do not consume physical screen space when
+displayed.
+
+If you want the user to be able to get at the line later, (with
+@key{C-p} for example), you must call @code{add_history()} to save the
+line away in a @dfn{history} list of such lines.
+
+@example
+@code{add_history (line)};
+@end example
+
+@noindent
+For full details on the GNU History Library, see the associated manual.
+
+It is preferable to avoid saving empty lines on the history list, since
+users rarely have a burning need to reuse a blank line. Here is
+a function which usefully replaces the standard @code{gets()} library
+function, and has the advantage of no static buffer to overflow:
+
+@example
+/* A static variable for holding the line. */
+static char *line_read = (char *)NULL;
+
+/* Read a string, and return a pointer to it.
+ Returns NULL on EOF. */
+char *
+rl_gets ()
+@{
+ /* If the buffer has already been allocated,
+ return the memory to the free pool. */
+ if (line_read)
+ @{
+ free (line_read);
+ line_read = (char *)NULL;
+ @}
+
+ /* Get a line from the user. */
+ line_read = readline ("");
+
+ /* If the line has any text in it,
+ save it on the history. */
+ if (line_read && *line_read)
+ add_history (line_read);
+
+ return (line_read);
+@}
+@end example
+
+This function gives the user the default behaviour of @key{TAB}
+completion: completion on file names. If you do not want Readline to
+complete on filenames, you can change the binding of the @key{TAB} key
+with @code{rl_bind_key()}.
+
+@example
+@code{int rl_bind_key (int @var{key}, rl_command_func_t *@var{function});}
+@end example
+
+@code{rl_bind_key()} takes two arguments: @var{key} is the character that
+you want to bind, and @var{function} is the address of the function to
+call when @var{key} is pressed. Binding @key{TAB} to @code{rl_insert()}
+makes @key{TAB} insert itself.
+@code{rl_bind_key()} returns non-zero if @var{key} is not a valid
+ASCII character code (between 0 and 255).
+
+Thus, to disable the default @key{TAB} behavior, the following suffices:
+@example
+@code{rl_bind_key ('\t', rl_insert);}
+@end example
+
+This code should be executed once at the start of your program; you
+might write a function called @code{initialize_readline()} which
+performs this and other desired initializations, such as installing
+custom completers (@pxref{Custom Completers}).
+
+@node Custom Functions
+@section Custom Functions
+
+Readline provides many functions for manipulating the text of
+the line, but it isn't possible to anticipate the needs of all
+programs. This section describes the various functions and variables
+defined within the Readline library which allow a user program to add
+customized functionality to Readline.
+
+Before declaring any functions that customize Readline's behavior, or
+using any functionality Readline provides in other code, an
+application writer should include the file @code{<readline/readline.h>}
+in any file that uses Readline's features. Since some of the definitions
+in @code{readline.h} use the @code{stdio} library, the file
+@code{<stdio.h>} should be included before @code{readline.h}.
+
+@code{readline.h} defines a C preprocessor variable that should
+be treated as an integer, @code{RL_READLINE_VERSION}, which may
+be used to conditionally compile application code depending on
+the installed Readline version. The value is a hexadecimal
+encoding of the major and minor version numbers of the library,
+of the form 0x@var{MMmm}. @var{MM} is the two-digit major
+version number; @var{mm} is the two-digit minor version number. 
+For Readline 4.2, for example, the value of
+@code{RL_READLINE_VERSION} would be @code{0x0402}. 
+
+@menu
+* Readline Typedefs::	C declarations to make code readable.
+* Function Writing::	Variables and calling conventions.
+@end menu
+
+@node Readline Typedefs
+@subsection Readline Typedefs
+
+For readability, we declare a number of new object types, all pointers
+to functions.
+
+The reason for declaring these new types is to make it easier to write
+code describing pointers to C functions with appropriately prototyped
+arguments and return values.
+
+For instance, say we want to declare a variable @var{func} as a pointer
+to a function which takes two @code{int} arguments and returns an
+@code{int} (this is the type of all of the Readline bindable functions).
+Instead of the classic C declaration
+
+@code{int (*func)();}
+
+@noindent
+or the ANSI-C style declaration
+
+@code{int (*func)(int, int);}
+
+@noindent
+we may write
+
+@code{rl_command_func_t *func;}
+
+The full list of function pointer types available is
+
+@table @code
+@item typedef int rl_command_func_t (int, int);
+
+@item typedef char *rl_compentry_func_t (const char *, int);
+
+@item typedef char **rl_completion_func_t (const char *, int, int);
+
+@item typedef char *rl_quote_func_t (char *, int, char *);
+
+@item typedef char *rl_dequote_func_t (char *, int);
+
+@item typedef int rl_compignore_func_t (char **);
+
+@item typedef void rl_compdisp_func_t (char **, int, int);
+
+@item typedef int rl_hook_func_t (void);
+
+@item typedef int rl_getc_func_t (FILE *);
+
+@item typedef int rl_linebuf_func_t (char *, int);
+
+@item typedef int rl_intfunc_t (int);
+@item #define rl_ivoidfunc_t rl_hook_func_t
+@item typedef int rl_icpfunc_t (char *);
+@item typedef int rl_icppfunc_t (char **);
+
+@item typedef void rl_voidfunc_t (void);

+@item typedef void rl_vcppfunc_t (char **);
+
+@end table
+
+@node Function Writing
+@subsection Writing a New Function
+
+In order to write new functions for Readline, you need to know the
+calling conventions for keyboard-invoked functions, and the names of the
+variables that describe the current state of the line read so far.
+
+The calling sequence for a command @code{foo} looks like
+
+@example
+@code{int foo (int count, int key)}
+@end example
+
+@noindent
+where @var{count} is the numeric argument (or 1 if defaulted) and
+@var{key} is the key that invoked this function.
+
+It is completely up to the function as to what should be done with the
+numeric argument. Some functions use it as a repeat count, some
+as a flag, and others to choose alternate behavior (refreshing the current
+line as opposed to refreshing the screen, for example). Some choose to
+ignore it. In general, if a
+function uses the numeric argument as a repeat count, it should be able
+to do something useful with both negative and positive arguments.
+At the very least, it should be aware that it can be passed a
+negative argument.
+
+A command function should return 0 if its action completes successfully,
+and a value greater than zero if some error occurs.
+This is the convention obeyed by all of the builtin Readline bindable
+command functions.
+
+@node Readline Variables
+@section Readline Variables
+
+These variables are available to function writers.
+
+@deftypevar {char *} rl_line_buffer
+This is the line gathered so far. You are welcome to modify the
+contents of the line, but see @ref{Allowing Undoing}. The
+function @code{rl_extend_line_buffer} is available to increase
+the memory allocated to @code{rl_line_buffer}.
+@end deftypevar
+
+@deftypevar int rl_point
+The offset of the current cursor position in @code{rl_line_buffer}
+(the @emph{point}).
+@end deftypevar
+
+@deftypevar int rl_end
+The number of characters present in @code{rl_line_buffer}. When
+@code{rl_point} is at the end of the line, @code{rl_point} and
+@code{rl_end} are equal.
+@end deftypevar
+
+@deftypevar int rl_mark
+The @var{mark} (saved position) in the current line. If set, the mark
+and point define a @emph{region}.
+@end deftypevar
+
+@deftypevar int rl_done
+Setting this to a non-zero value causes Readline to return the current
+line immediately.
+@end deftypevar
+
+@deftypevar int rl_num_chars_to_read
+Setting this to a positive value before calling @code{readline()} causes
+Readline to return after accepting that many characters, rather
+than reading up to a character bound to @code{accept-line}.
+@end deftypevar
+
+@deftypevar int rl_pending_input
+Setting this to a value makes it the next keystroke read. This is a
+way to stuff a single character into the input stream.
+@end deftypevar
+
+@deftypevar int rl_dispatching
+Set to a non-zero value if a function is being called from a key binding;
+zero otherwise. Application functions can test this to discover whether
+they were called directly or by Readline's dispatching mechanism.
+@end deftypevar
+
+@deftypevar int rl_erase_empty_line
+Setting this to a non-zero value causes Readline to completely erase
+the current line, including any prompt, any time a newline is typed as
+the only character on an otherwise-empty line. The cursor is moved to
+the beginning of the newly-blank line.
+@end deftypevar
+
+@deftypevar {char *} rl_prompt
+The prompt Readline uses. This is set from the argument to
+@code{readline()}, and should not be assigned to directly.
+The @code{rl_set_prompt()} function (@pxref{Redisplay}) may
+be used to modify the prompt string after calling @code{readline()}.
+@end deftypevar
+
+@deftypevar {char *} rl_display_prompt
+The string displayed as the prompt. This is usually identical to
+@var{rl_prompt}, but may be changed temporarily by functions that
+use the prompt string as a message area, such as incremental search.
+@end deftypevar
+
+@deftypevar int rl_already_prompted
+If an application wishes to display the prompt itself, rather than have
+Readline do it the first time @code{readline()} is called, it should set
+this variable to a non-zero value after displaying the prompt.
+The prompt must also be passed as the argument to @code{readline()} so
+the redisplay functions can update the display properly.
+The calling application is responsible for managing the value; Readline
+never sets it.
+@end deftypevar
+
+@deftypevar {const char *} rl_library_version
+The version number of this revision of the library.
+@end deftypevar
+
+@deftypevar int rl_readline_version
+An integer encoding the current version of the library. The encoding is
+of the form 0x@var{MMmm}, where @var{MM} is the two-digit major version
+number, and @var{mm} is the two-digit minor version number.
+For example, for Readline-4.2, @code{rl_readline_version} would have the
+value 0x0402.
+@end deftypevar
+
+@deftypevar {int} rl_gnu_readline_p
+Always set to 1, denoting that this is @sc{gnu} readline rather than some
+emulation.
+@end deftypevar
+
+@deftypevar {const char *} rl_terminal_name
+The terminal type, used for initialization. If not set by the application,
+Readline sets this to the value of the @env{TERM} environment variable
+the first time it is called.
+@end deftypevar
+
+@deftypevar {const char *} rl_readline_name
+This variable is set to a unique name by each application using Readline.
+The value allows conditional parsing of the inputrc file
+(@pxref{Conditional Init Constructs}).
+@end deftypevar
+
+@deftypevar {FILE *} rl_instream
+The stdio stream from which Readline reads input.
+If @code{NULL}, Readline defaults to @var{stdin}.
+@end deftypevar
+
+@deftypevar {FILE *} rl_outstream
+The stdio stream to which Readline performs output.
+If @code{NULL}, Readline defaults to @var{stdout}.
+@end deftypevar
+
+@deftypevar int rl_prefer_env_winsize
+If non-zero, Readline gives values found in the @env{LINES} and
+@env{COLUMNS} environment variables greater precedence than values fetched
+from the kernel when computing the screen dimensions.
+@end deftypevar
+
+@deftypevar {rl_command_func_t *} rl_last_func
+The address of the last command function Readline executed. May be used to
+test whether or not a function is being executed twice in succession, for
+example.
+@end deftypevar

+is no keyboard input.
+@end deftypevar
+
+@deftypevar {rl_getc_func_t *} rl_getc_function
+If non-zero, Readline will call indirectly through this pointer
+to get a character from the input stream. By default, it is set to
+@code{rl_getc}, the default Readline character input function
+(@pxref{Character Input}).
+In general, an application that sets @var{rl_getc_function} should consider
+setting @var{rl_input_available_hook} as well.

+call is interrupted when Readline is reading terminal input.
+@end deftypevar
+
+@deftypevar {rl_hook_func_t *} rl_input_available_hook
+If non-zero, Readline will use this function's return value when it needs
+to determine whether or not there is available input on the current input
+source.
+The default hook checks @code{rl_instream}; if an application is using a
+different input source, it should set the hook appropriately.
+Readline queries for available input when implementing intra-key-sequence
+timeouts during input and incremental searches.
+This may use an application-specific timeout before returning a value;
+Readline uses the value passed to @code{rl_set_keyboard_input_timeout()}
+or the value of the user-settable @var{keyseq-timeout} variable.
+This is designed for use by applications using Readline's callback interface
+(@pxref{Alternate Interface}), which may not use the traditional
+@code{read(2)} and file descriptor interface, or other applications using
+a different input mechanism.
+If an application uses an input mechanism or hook that can potentially exceed
+the value of @var{keyseq-timeout}, it should increase the timeout or set
+this hook appropriately even when not using the callback interface.
+In general, an application that sets @var{rl_getc_function} should consider
+setting @var{rl_input_available_hook} as well.

+@node Function Naming
+@subsection Naming a Function
+
+The user can dynamically change the bindings of keys while using
+Readline. This is done by representing the function with a descriptive
+name. The user is able to type the descriptive name when referring to
+the function. Thus, in an init file, one might find
+
+@example
+Meta-Rubout:	backward-kill-word
+@end example
+
+This binds the keystroke @key{Meta-Rubout} to the function
+@emph{descriptively} named @code{backward-kill-word}. You, as the
+programmer, should bind the functions you write to descriptive names as
+well. Readline provides a function for doing that:
+
+@deftypefun int rl_add_defun (const char *name, rl_command_func_t *function, int key)
+Add @var{name} to the list of named functions. Make @var{function} be
+the function that gets called. If @var{key} is not -1, then bind it to
+@var{function} using @code{rl_bind_key()}.
+@end deftypefun
+
+Using this function alone is sufficient for most applications.
+It is the recommended way to add a few functions to the default
+functions that Readline has built in.
+If you need to do something other than adding a function to Readline,
+you may need to use the underlying functions described below.
+
+@node Keymaps
+@subsection Selecting a Keymap
+
+Key bindings take place on a @dfn{keymap}. The keymap is the
+association between the keys that the user types and the functions that
+get run. You can make your own keymaps, copy existing keymaps, and tell
+Readline which keymap to use.
+
+@deftypefun Keymap rl_make_bare_keymap (void)
+Returns a new, empty keymap. The space for the keymap is allocated with
+@code{malloc()}; the caller should free it by calling
+@code{rl_free_keymap()} when done.
+@end deftypefun
+
+@deftypefun Keymap rl_copy_keymap (Keymap map)
+Return a new keymap which is a copy of @var{map}.
+@end deftypefun
+
+@deftypefun Keymap rl_make_keymap (void)
+Return a new keymap with the printing characters bound to rl_insert,
+the lowercase Meta characters bound to run their equivalents, and
+the Meta digits bound to produce numeric arguments.
+@end deftypefun
+
+@deftypefun void rl_discard_keymap (Keymap keymap)
+Free the storage associated with the data in @var{keymap}.
+The caller should free @var{keymap}.
+@end deftypefun
+
+@deftypefun void rl_free_keymap (Keymap keymap)
+Free all storage associated with @var{keymap}. This calls
+@code{rl_discard_keymap} to free subordindate keymaps and macros.
+@end deftypefun
+
+@deftypefun int rl_empty_keymap (Keymap keymap)
+Return non-zero if there are no keys bound to functions in @var{keymap};
+zero if there are any keys bound.
+@end deftypefun
+
+Readline has several internal keymaps. These functions allow you to
+change which keymap is active.
+
+@deftypefun Keymap rl_get_keymap (void)
+Returns the currently active keymap.
+@end deftypefun
+
+@deftypefun void rl_set_keymap (Keymap keymap)
+Makes @var{keymap} the currently active keymap.
+@end deftypefun
+
+@deftypefun Keymap rl_get_keymap_by_name (const char *name)
+Return the keymap matching @var{name}. @var{name} is one which would
+be supplied in a @code{set keymap} inputrc line (@pxref{Readline Init File}).
+@end deftypefun
+
+@deftypefun {char *} rl_get_keymap_name (Keymap keymap)
+Return the name matching @var{keymap}. @var{name} is one which would
+be supplied in a @code{set keymap} inputrc line (@pxref{Readline Init File}).
+@end deftypefun
+
+@deftypefun int rl_set_keymap_name (const char *name, Keymap keymap)
+Set the name of @var{keymap}. This name will then be "registered" and
+available for use in a @code{set keymap} inputrc directive
+@pxref{Readline Init File}).
+The @var{name} may not be one of Readline's builtin keymap names;
+you may not add a different name for one of Readline's builtin keymaps.
+You may replace the name associated with a given keymap by calling this
+function more than once with the same @var{keymap} argument.
+You may associate a registered @var{name} with a new keymap by calling this
+function more than once with the same @var{name} argument.
+There is no way to remove a named keymap once the name has been
+registered.
+Readline will make a copy of @var{name}.
+The return value is greater than zero unless @var{name} is one of
+Readline's builtin keymap names or @var{keymap} is one of Readline's
+builtin keymaps.
+@end deftypefun
+
+@node Binding Keys
+@subsection Binding Keys
+
+Key sequences are associate with functions through the keymap.
+Readline has several internal keymaps: @code{emacs_standard_keymap},
+@code{emacs_meta_keymap}, @code{emacs_ctlx_keymap},
+@code{vi_movement_keymap}, and @code{vi_insertion_keymap}.
+@code{emacs_standard_keymap} is the default, and the examples in
+this manual assume that.
+
+Since @code{readline()} installs a set of default key bindings the first
+time it is called, there is always the danger that a custom binding
+installed before the first call to @code{readline()} will be overridden.
+An alternate mechanism is to install custom key bindings in an
+initialization function assigned to the @code{rl_startup_hook} variable
+(@pxref{Readline Variables}).
+
+These functions manage key bindings.
+
+@deftypefun int rl_bind_key (int key, rl_command_func_t *function)

+
+@deftypefun int rl_generic_bind (int type, const char *keyseq, char *data, Keymap map)
+Bind the key sequence represented by the string @var{keyseq} to the arbitrary

+@node Allowing Undoing
+@subsection Allowing Undoing
+
+Supporting the undo command is a painless thing, and makes your
+functions much more useful. It is certainly easy to try
+something if you know you can undo it.
+
+If your function simply inserts text once, or deletes text once, and
+uses @code{rl_insert_text()} or @code{rl_delete_text()} to do it, then
+undoing is already done for you automatically.
+
+If you do multiple insertions or multiple deletions, or any combination
+of these operations, you should group them together into one operation.
+This is done with @code{rl_begin_undo_group()} and
+@code{rl_end_undo_group()}.
+
+The types of events that can be undone are:
+
+@smallexample
+enum undo_code @{ UNDO_DELETE, UNDO_INSERT, UNDO_BEGIN, UNDO_END @}; 
+@end smallexample
+
+Notice that @code{UNDO_DELETE} means to insert some text, and
+@code{UNDO_INSERT} means to delete some text. That is, the undo code
+tells what to undo, not how to undo it. @code{UNDO_BEGIN} and
+@code{UNDO_END} are tags added by @code{rl_begin_undo_group()} and
+@code{rl_end_undo_group()}.
+
+@deftypefun int rl_begin_undo_group (void)
+Begins saving undo information in a group construct. The undo
+information usually comes from calls to @code{rl_insert_text()} and
+@code{rl_delete_text()}, but could be the result of calls to
+@code{rl_add_undo()}.
+@end deftypefun
+
+@deftypefun int rl_end_undo_group (void)
+Closes the current undo group started with @code{rl_begin_undo_group
+()}. There should be one call to @code{rl_end_undo_group()}
+for each call to @code{rl_begin_undo_group()}.
+@end deftypefun
+
+@deftypefun void rl_add_undo (enum undo_code what, int start, int end, char *text)
+Remember how to undo an event (according to @var{what}). The affected
+text runs from @var{start} to @var{end}, and encompasses @var{text}.
+@end deftypefun
+
+@deftypefun void rl_free_undo_list (void)
+Free the existing undo list.
+@end deftypefun
+
+@deftypefun int rl_do_undo (void)
+Undo the first thing on the undo list. Returns @code{0} if there was
+nothing to undo, non-zero if something was undone.
+@end deftypefun
+
+Finally, if you neither insert nor delete text, but directly modify the
+existing text (e.g., change its case), call @code{rl_modifying()}
+once, just before you modify the text. You must supply the indices of
+the text range that you are going to modify.
+
+@deftypefun int rl_modifying (int start, int end)
+Tell Readline to save the text between @var{start} and @var{end} as a
+single undo unit. It is assumed that you will subsequently modify
+that text.

+@node Readline Signal Handling
+@section Readline Signal Handling
+
+Signals are asynchronous events sent to a process by the Unix kernel,
+sometimes on behalf of another process. They are intended to indicate
+exceptional events, like a user pressing the interrupt key on his terminal,
+or a network connection being broken. There is a class of signals that can
+be sent to the process currently reading input from the keyboard. Since
+Readline changes the terminal attributes when it is called, it needs to
+perform special processing when such a signal is received in order to
+restore the terminal to a sane state, or provide application writers with
+functions to do so manually. 
+
+Readline contains an internal signal handler that is installed for a
+number of signals (@code{SIGINT}, @code{SIGQUIT}, @code{SIGTERM},
+@code{SIGHUP}, 
+@code{SIGALRM}, @code{SIGTSTP}, @code{SIGTTIN}, and @code{SIGTTOU}).
+When one of these signals is received, the signal handler
+will reset the terminal attributes to those that were in effect before
+@code{readline()} was called, reset the signal handling to what it was
+before @code{readline()} was called, and resend the signal to the calling
+application.
+If and when the calling application's signal handler returns, Readline
+will reinitialize the terminal and continue to accept input.
+When a @code{SIGINT} is received, the Readline signal handler performs
+some additional work, which will cause any partially-entered line to be
+aborted (see the description of @code{rl_free_line_state()} below).
+
+There is an additional Readline signal handler, for @code{SIGWINCH}, which
+the kernel sends to a process whenever the terminal's size changes (for
+example, if a user resizes an @code{xterm}). The Readline @code{SIGWINCH}
+handler updates Readline's internal screen size information, and then calls
+any @code{SIGWINCH} signal handler the calling application has installed. 
+Readline calls the application's @code{SIGWINCH} signal handler without
+resetting the terminal to its original state. If the application's signal
+handler does more than update its idea of the terminal size and return (for
+example, a @code{longjmp} back to a main processing loop), it @emph{must}
+call @code{rl_cleanup_after_signal()} (described below), to restore the
+terminal state.
+
+When an application is using the callback interface
+(@pxref{Alternate Interface}), Readline installs signal handlers only for
+the duration of the call to @code{rl_callback_read_char}. Applications
+using the callback interface should be prepared to clean up Readline's
+state if they wish to handle the signal before the line handler completes
+and restores the terminal state.
+
+If an application using the callback interface wishes to have Readline
+install its signal handlers at the time the application calls
+@code{rl_callback_handler_install} and remove them only when a complete
+line of input has been read, it should set the
+@code{rl_persistent_signal_handlers} variable to a non-zero value.
+This allows an application to defer all of the handling of the signals
+Readline catches to Readline.
+Applications should use this variable with care; it can result in Readline
+catching signals and not acting on them (or allowing the application to react
+to them) until the application calls @code{rl_callback_read_char}. This
+can result in an application becoming less responsive to keyboard signals
+like SIGINT.
+If an application does not want or need to perform any signal handling, or
+does not need to do any processing between calls to @code{rl_callback_read_char},
+setting this variable may be desirable.
+
+Readline provides two variables that allow application writers to
+control whether or not it will catch certain signals and act on them
+when they are received. It is important that applications change the
+values of these variables only when calling @code{readline()}, not in
+a signal handler, so Readline's internal signal state is not corrupted.

+
+The default value of @code{rl_catch_sigwinch} is 1.
+@end deftypevar
+
+@deftypevar int rl_persistent_signal_handlers
+If an application using the callback interface wishes Readline's signal

+for example), 
+Readline provides convenience functions to do the necessary terminal
+and internal state cleanup upon receipt of a signal.
+
+@deftypefun int rl_pending_signal (void)
+Return the signal number of the most recent signal Readline received but
+has not yet handled, or 0 if there is no pending signal.
+@end deftypefun
+
+@deftypefun void rl_cleanup_after_signal (void)
+This function will reset the state of the terminal to what it was before

+This will free any partial state associated with the current input line
+(undo information, any partial history entry, any partially-entered

+
+If an application wants to force Readline to handle any signals that

+@node How Completing Works
+@subsection How Completing Works
+
+In order to complete some text, the full list of possible completions
+must be available. That is, it is not possible to accurately
+expand a partial word without knowing all of the possible words
+which make sense in that context. The Readline library provides
+the user interface to completion, and two of the most common
+completion functions: filename and username. For completing other types
+of text, you must write your own completion function. This section
+describes exactly what such functions must do, and provides an example.
+
+There are three major functions used to perform completion:
+
+@enumerate
+@item
+The user-interface function @code{rl_complete()}. This function is
+called with the same arguments as other bindable Readline functions:
+@var{count} and @var{invoking_key}.
+It isolates the word to be completed and calls
+@code{rl_completion_matches()} to generate a list of possible completions.
+It then either lists the possible completions, inserts the possible
+completions, or actually performs the
+completion, depending on which behavior is desired.
+
+@item
+The internal function @code{rl_completion_matches()} uses an
+application-supplied @dfn{generator} function to generate the list of
+possible matches, and then returns the array of these matches.
+The caller should place the address of its generator function in
+@code{rl_completion_entry_function}.
+
+@item
+The generator function is called repeatedly from
+@code{rl_completion_matches()}, returning a string each time. The
+arguments to the generator function are @var{text} and @var{state}.
+@var{text} is the partial word to be completed. @var{state} is zero the
+first time the function is called, allowing the generator to perform
+any necessary initialization, and a positive non-zero integer for
+each subsequent call. The generator function returns
+@code{(char *)NULL} to inform @code{rl_completion_matches()} that there are
+no more possibilities left. Usually the generator function computes the
+list of possible completions when @var{state} is zero, and returns them
+one at a time on subsequent calls. Each string the generator function
+returns as a match must be allocated with @code{malloc()}; Readline
+frees the strings when it has finished with them.
+Such a generator function is referred to as an
+@dfn{application-specific completion function}.
+
+@end enumerate
+
+@deftypefun int rl_complete (int ignore, int invoking_key)
+Complete the word at or before point. You have supplied the function
+that does the initial simple matching selection algorithm (see
+@code{rl_completion_matches()}). The default is to do filename completion.
+@end deftypefun
+
+@deftypevar {rl_compentry_func_t *} rl_completion_entry_function
+This is a pointer to the generator function for
+@code{rl_completion_matches()}.
+If the value of @code{rl_completion_entry_function} is
+@code{NULL} then the default filename generator
+function, @code{rl_filename_completion_function()}, is used.
+An @dfn{application-specific completion function} is a function whose
+address is assigned to @code{rl_completion_entry_function} and whose
+return values are used to generate possible completions.
+@end deftypevar
+
+@node Completion Functions
+@subsection Completion Functions
+
+Here is the complete list of callable completion functions present in
+Readline.
+
+@deftypefun int rl_complete_internal (int what_to_do)
+Complete the word at or before point. @var{what_to_do} says what to do
+with the completion. A value of @samp{?} means list the possible
+completions. @samp{TAB} means do standard completion. @samp{*} means
+insert all of the possible completions. @samp{!} means to display
+all of the possible completions, if there is more than one, as well as
+performing partial completion. @samp{@@} is similar to @samp{!}, but
+possible completions are not listed if the possible completions share
+a common prefix.
+@end deftypefun
+
+@deftypefun int rl_complete (int ignore, int invoking_key)
+Complete the word at or before point. You have supplied the function
+that does the initial simple matching selection algorithm (see
+@code{rl_completion_matches()} and @code{rl_completion_entry_function}).
+The default is to do filename
+completion. This calls @code{rl_complete_internal()} with an
+argument depending on @var{invoking_key}.
+@end deftypefun
+
+@deftypefun int rl_possible_completions (int count, int invoking_key)
+List the possible completions. See description of @code{rl_complete
+()}. This calls @code{rl_complete_internal()} with an argument of
+@samp{?}.
+@end deftypefun
+
+@deftypefun int rl_insert_completions (int count, int invoking_key)
+Insert the list of possible completions into the line, deleting the
+partially-completed word. See description of @code{rl_complete()}.
+This calls @code{rl_complete_internal()} with an argument of @samp{*}.
+@end deftypefun
+
+@deftypefun int rl_completion_mode (rl_command_func_t *cfunc)
+Returns the appropriate value to pass to @code{rl_complete_internal()}
+depending on whether @var{cfunc} was called twice in succession and
+the values of the @code{show-all-if-ambiguous} and
+@code{show-all-if-unmodified} variables.
+Application-specific completion functions may use this function to present
+the same interface as @code{rl_complete()}.
+@end deftypefun
+
+@deftypefun {char **} rl_completion_matches (const char *text, rl_compentry_func_t *entry_func)
+Returns an array of strings which is a list of completions for
+@var{text}. If there are no completions, returns @code{NULL}.
+The first entry in the returned array is the substitution for @var{text}.
+The remaining entries are the possible completions. The array is
+terminated with a @code{NULL} pointer.
+
+@var{entry_func} is a function of two args, and returns a
+@code{char *}. The first argument is @var{text}. The second is a
+state argument; it is zero on the first call, and non-zero on subsequent
+calls. @var{entry_func} returns a @code{NULL} pointer to the caller
+when there are no more matches.
+@end deftypefun
+
+@deftypefun {char *} rl_filename_completion_function (const char *text, int state)
+A generator function for filename completion in the general case.
+@var{text} is a partial filename.
+The Bash source is a useful reference for writing application-specific
+completion functions (the Bash completion functions call this and other
+Readline functions).
+@end deftypefun
+
+@deftypefun {char *} rl_username_completion_function (const char *text, int state)
+A completion generator for usernames. @var{text} contains a partial
+username preceded by a random character (usually @samp{~}). As with all
+completion generators, @var{state} is zero on the first call and non-zero
+for subsequent calls.
+@end deftypefun
+
+@node Completion Variables
+@subsection Completion Variables
+
+@deftypevar {rl_compentry_func_t *} rl_completion_entry_function
+A pointer to the generator function for @code{rl_completion_matches()}.
+@code{NULL} means to use @code{rl_filename_completion_function()},
+the default filename completer.
+@end deftypevar
+
+@deftypevar {rl_completion_func_t *} rl_attempted_completion_function
+A pointer to an alternative function to create matches.
+The function is called with @var{text}, @var{start}, and @var{end}.
+@var{start} and @var{end} are indices in @code{rl_line_buffer} defining
+the boundaries of @var{text}, which is a character string.
+If this function exists and returns @code{NULL}, or if this variable is
+set to @code{NULL}, then @code{rl_complete()} will call the value of
+@code{rl_completion_entry_function} to generate matches, otherwise the
+array of strings returned will be used.
+If this function sets the @code{rl_attempted_completion_over}
+variable to a non-zero value, Readline will not perform its default
+completion even if this function returns no matches.
+@end deftypevar
+
+@deftypevar {rl_quote_func_t *} rl_filename_quoting_function
+A pointer to a function that will quote a filename in an
+application-specific fashion. This is called if filename completion is being
+attempted and one of the characters in @code{rl_filename_quote_characters}
+appears in a completed filename. The function is called with
+@var{text}, @var{match_type}, and @var{quote_pointer}. The @var{text}
+is the filename to be quoted. The @var{match_type} is either
+@code{SINGLE_MATCH}, if there is only one completion match, or
+@code{MULT_MATCH}. Some functions use this to decide whether or not to
+insert a closing quote character. The @var{quote_pointer} is a pointer
+to any opening quote character the user typed. Some functions choose
+to reset this character.
+@end deftypevar
+
+@deftypevar {rl_dequote_func_t *} rl_filename_dequoting_function
+A pointer to a function that will remove application-specific quoting
+characters from a filename before completion is attempted, so those
+characters do not interfere with matching the text against names in
+the filesystem. It is called with @var{text}, the text of the word
+to be dequoted, and @var{quote_char}, which is the quoting character 
+that delimits the filename (usually @samp{'} or @samp{"}). If
+@var{quote_char} is zero, the filename was not in an embedded string.
+@end deftypevar
+
+@deftypevar {rl_linebuf_func_t *} rl_char_is_quoted_p
+A pointer to a function to call that determines whether or not a specific
+character in the line buffer is quoted, according to whatever quoting
+mechanism the program calling Readline uses. The function is called with
+two arguments: @var{text}, the text of the line, and @var{index}, the
+index of the character in the line. It is used to decide whether a
+character found in @code{rl_completer_word_break_characters} should be
+used to break words for the completer.
+@end deftypevar
+
+@deftypevar {rl_compignore_func_t *} rl_ignore_some_completions_function
+This function, if defined, is called by the completer when real filename
+completion is done, after all the matching names have been generated.
+It is passed a @code{NULL} terminated array of matches.
+The first element (@code{matches0}) is the
+maximal substring common to all matches. This function can
+re-arrange the list of matches as required, but each element deleted
+from the array must be freed.
+@end deftypevar
+
+@deftypevar {rl_icppfunc_t *} rl_directory_completion_hook
+This function, if defined, is allowed to modify the directory portion
+of filenames Readline completes.
+It could be used to expand symbolic links or shell variables in pathnames.
+It is called with the address of a string (the current directory name) as an
+argument, and may modify that string.
+If the string is replaced with a new string, the old value should be freed.
+Any modified directory name should have a trailing slash.
+The modified value will be used as part of the completion, replacing
+the directory portion of the pathname the user typed.
+At the least, even if no other expansion is performed, this function should
+remove any quote characters from the directory name, because its result will
+be passed directly to @code{opendir()}.
+
+The directory completion hook returns an integer that should be non-zero if
+the function modifies its directory argument.
+The function should not modify the directory argument if it returns 0.
+@end deftypevar
+
+@deftypevar {rl_icppfunc_t *} rl_directory_rewrite_hook;
+If non-zero, this is the address of a function to call when completing
+a directory name. This function takes the address of the directory name
+to be modified as an argument. Unlike @code{rl_directory_completion_hook},
+it only modifies the directory name used in @code{opendir}, not what is
+displayed when the possible completions are printed or inserted. It is
+called before rl_directory_completion_hook.
+At the least, even if no other expansion is performed, this function should
+remove any quote characters from the directory name, because its result will
+be passed directly to @code{opendir()}.
+
+The directory rewrite hook returns an integer that should be non-zero if
+the function modifies its directory argument.
+The function should not modify the directory argument if it returns 0.
+@end deftypevar
+
+@deftypevar {rl_icppfunc_t *} rl_filename_stat_hook
+If non-zero, this is the address of a function for the completer to
+call before deciding which character to append to a completed name.
+This function modifies its filename name argument, and the modified value
+is passed to @code{stat()} to determine the file's type and characteristics.
+This function does not need to remove quote characters from the filename.
+
+The stat hook returns an integer that should be non-zero if
+the function modifies its directory argument.
+The function should not modify the directory argument if it returns 0.
+@end deftypevar
+
+@deftypevar {rl_dequote_func_t *} rl_filename_rewrite_hook
+If non-zero, this is the address of a function called when reading
+directory entries from the filesystem for completion and comparing
+them to the partial word to be completed. The function should
+perform any necessary application or system-specific conversion on
+the filename, such as converting between character sets or converting
+from a filesystem format to a character input format.
+The function takes two arguments: @var{fname}, the filename to be converted,
+and @var{fnlen}, its length in bytes.
+It must either return its first argument (if no conversion takes place)
+or the converted filename in newly-allocated memory. The converted
+form is used to compare against the word to be completed, and, if it
+matches, is added to the list of matches. Readline will free the
+allocated string.
+@end deftypevar
+
+@deftypevar {rl_compdisp_func_t *} rl_completion_display_matches_hook
+If non-zero, then this is the address of a function to call when
+completing a word would normally display the list of possible matches.
+This function is called in lieu of Readline displaying the list.
+It takes three arguments:
+(@code{char **}@var{matches}, @code{int} @var{num_matches}, @code{int} @var{max_length})
+where @var{matches} is the array of matching strings,
+@var{num_matches} is the number of strings in that array, and
+@var{max_length} is the length of the longest string in that array.
+Readline provides a convenience function, @code{rl_display_match_list},
+that takes care of doing the display to Readline's output stream.
+You may call that function from this hook.
+@end deftypevar
+
+@deftypevar {const char *} rl_basic_word_break_characters
+The basic list of characters that signal a break between words for the
+completer routine. The default value of this variable is the characters
+which break words for completion in Bash:
+@code{" \t\n\"\\'`@@$><=;|&@{("}.
+@end deftypevar
+
+@deftypevar {const char *} rl_basic_quote_characters
+A list of quote characters which can cause a word break.
+@end deftypevar
+
+@deftypevar {const char *} rl_completer_word_break_characters
+The list of characters that signal a break between words for
+@code{rl_complete_internal()}. The default list is the value of
+@code{rl_basic_word_break_characters}.
+@end deftypevar
+
+@deftypevar {rl_cpvfunc_t *} rl_completion_word_break_hook
+If non-zero, this is the address of a function to call when Readline is
+deciding where to separate words for word completion. It should return
+a character string like @code{rl_completer_word_break_characters} to be
+used to perform the current completion. The function may choose to set
+@code{rl_completer_word_break_characters} itself. If the function
+returns @code{NULL}, @code{rl_completer_word_break_characters} is used.
+@end deftypevar
+
+@deftypevar {const char *} rl_completer_quote_characters
+A list of characters which can be used to quote a substring of the line.
+Completion occurs on the entire substring, and within the substring
+@code{rl_completer_word_break_characters} are treated as any other character,
+unless they also appear within this list.
+@end deftypevar
+
+@deftypevar {const char *} rl_filename_quote_characters
+A list of characters that cause a filename to be quoted by the completer
+when they appear in a completed filename. The default is the null string.
+@end deftypevar
+
+@deftypevar {const char *} rl_special_prefixes
+The list of characters that are word break characters, but should be
+left in @var{text} when it is passed to the completion function.
+Programs can use this to help determine what kind of completing to do.
+For instance, Bash sets this variable to "$@@" so that it can complete
+shell variables and hostnames.
+@end deftypevar
+
+@deftypevar int rl_completion_query_items
+Up to this many items will be displayed in response to a
+possible-completions call. After that, readline asks the user if she is sure
+she wants to see them all. The default value is 100. A negative value 
+indicates that Readline should never ask the user.
+@end deftypevar
+
+@deftypevar {int} rl_completion_append_character
+When a single completion alternative matches at the end of the command
+line, this character is appended to the inserted completion text. The
+default is a space character (@samp{ }). Setting this to the null
+character (@samp{\0}) prevents anything being appended automatically.
+This can be changed in application-specific completion functions to
+provide the ``most sensible word separator character'' according to
+an application-specific command line syntax specification.
+It is set to the default before any application-specific completion function
+is called, and may only be changed within such a function.
+@end deftypevar
+
+@deftypevar int rl_completion_suppress_append
+If non-zero, @var{rl_completion_append_character} is not appended to
+matches at the end of the command line, as described above.
+It is set to 0 before any application-specific completion function
+is called, and may only be changed within such a function.
+@end deftypevar
+
+@deftypevar int rl_completion_quote_character
+When Readline is completing quoted text, as delimited by one of the
+characters in @var{rl_completer_quote_characters}, it sets this variable
+to the quoting character found.
+This is set before any application-specific completion function is called.
+@end deftypevar
+
+@deftypevar int rl_completion_suppress_quote
+If non-zero, Readline does not append a matching quote character when
+performing completion on a quoted string.
+It is set to 0 before any application-specific completion function
+is called, and may only be changed within such a function.
+@end deftypevar
+
+@deftypevar int rl_completion_found_quote
+When Readline is completing quoted text, it sets this variable
+to a non-zero value if the word being completed contains or is delimited
+by any quoting characters, including backslashes.
+This is set before any application-specific completion function is called.
+@end deftypevar
+
+@deftypevar int rl_completion_mark_symlink_dirs
+If non-zero, a slash will be appended to completed filenames that are
+symbolic links to directory names, subject to the value of the
+user-settable @var{mark-directories} variable.
+This variable exists so that application-specific completion functions
+can override the user's global preference (set via the
+@var{mark-symlinked-directories} Readline variable) if appropriate.
+This variable is set to the user's preference before any
+application-specific completion function is called, so unless that
+function modifies the value, the user's preferences are honored.
+@end deftypevar
+
+@deftypevar int rl_ignore_completion_duplicates
+If non-zero, then duplicates in the matches are removed.
+The default is 1.
+@end deftypevar
+
+@deftypevar int rl_filename_completion_desired
+Non-zero means that the results of the matches are to be treated as
+filenames. This is @emph{always} zero when completion is attempted,
+and can only be changed
+within an application-specific completion function. If it is set to a
+non-zero value by such a function, directory names have a slash appended
+and Readline attempts to quote completed filenames if they contain any
+characters in @code{rl_filename_quote_characters} and
+@code{rl_filename_quoting_desired} is set to a non-zero value.
+@end deftypevar
+
+@deftypevar int rl_filename_quoting_desired
+Non-zero means that the results of the matches are to be quoted using
+double quotes (or an application-specific quoting mechanism) if the
+completed filename contains any characters in
+@code{rl_filename_quote_chars}. This is @emph{always} non-zero
+when completion is attempted, and can only be changed within an
+application-specific completion function.
+The quoting is effected via a call to the function pointed to
+by @code{rl_filename_quoting_function}.
+@end deftypevar
+
+@deftypevar int rl_attempted_completion_over
+If an application-specific completion function assigned to
+@code{rl_attempted_completion_function} sets this variable to a non-zero
+value, Readline will not perform its default filename completion even
+if the application's completion function returns no matches.
+It should be set only by an application's completion function.
+@end deftypevar
+
+@deftypevar int rl_sort_completion_matches
+If an application sets this variable to 0, Readline will not sort the
+list of completions (which implies that it cannot remove any duplicate
+completions). The default value is 1, which means that Readline will
+sort the completions and, depending on the value of
+@code{rl_ignore_completion_duplicates}, will attempt to remove duplicate
+matches.
+@end deftypevar
+

+@chapter Command Line Editing
+
+This chapter describes the basic features of the @sc{gnu}
+command line editing interface.
+@ifset BashFeatures
+Command line editing is provided by the Readline library, which is
+used by several different programs, including Bash.
+Command line editing is enabled by default when using an interactive shell,
+unless the @option{--noediting} option is supplied at shell invocation.
+Line editing is also used when using the @option{-e} option to the
+@code{read} builtin command (@pxref{Bash Builtins}).
+By default, the line editing commands are similar to those of Emacs.
+A vi-style line editing interface is also available.
+Line editing can be enabled at any time using the @option{-o emacs} or
+@option{-o vi} options to the @code{set} builtin command
+(@pxref{The Set Builtin}), or disabled using the @option{+o emacs} or 
+@option{+o vi} options to @code{set}.

+
+@node Introduction and Notation
+@section Introduction to Line Editing
+
+The following paragraphs describe the notation used to represent
+keystrokes.
+
+The text @kbd{C-k} is read as `Control-K' and describes the character
+produced when the @key{k} key is pressed while the Control key
+is depressed.
+
+The text @kbd{M-k} is read as `Meta-K' and describes the character
+produced when the Meta key (if you have one) is depressed, and the @key{k}
+key is pressed.
+The Meta key is labeled @key{ALT} on many keyboards.
+On keyboards with two keys labeled @key{ALT} (usually to either side of
+the space bar), the @key{ALT} on the left side is generally set to
+work as a Meta key.
+The @key{ALT} key on the right may also be configured to work as a
+Meta key or may be configured as some other modifier, such as a
+Compose key for typing accented characters.
+
+If you do not have a Meta or @key{ALT} key, or another key working as
+a Meta key, the identical keystroke can be generated by typing @key{ESC}
+@emph{first}, and then typing @key{k}.
+Either process is known as @dfn{metafying} the @key{k} key.
+
+The text @kbd{M-C-k} is read as `Meta-Control-k' and describes the
+character produced by @dfn{metafying} @kbd{C-k}.
+
+In addition, several keys have their own names. Specifically,
+@key{DEL}, @key{ESC}, @key{LFD}, @key{SPC}, @key{RET}, and @key{TAB} all
+stand for themselves when seen in this text, or in an init file
+(@pxref{Readline Init File}).
+If your keyboard lacks a @key{LFD} key, typing @key{C-j} will
+produce the desired character.
+The @key{RET} key may be labeled @key{Return} or @key{Enter} on
+some keyboards.
+
+@node Readline Interaction
+@section Readline Interaction
+@cindex interaction, readline
+
+Often during an interactive session you type in a long line of text,
+only to notice that the first word on the line is misspelled. The
+Readline library gives you a set of commands for manipulating the text
+as you type it in, allowing you to just fix your typo, and not forcing
+you to retype the majority of the line. Using these editing commands,
+you move the cursor to the place that needs correction, and delete or
+insert the text of the corrections. Then, when you are satisfied with
+the line, you simply press @key{RET}. You do not have to be at the
+end of the line to press @key{RET}; the entire line is accepted
+regardless of the location of the cursor within the line.

+
+@node Readline Bare Essentials
+@subsection Readline Bare Essentials
+@cindex notation, readline
+@cindex command editing
+@cindex editing command lines
+
+In order to enter characters into the line, simply type them. The typed
+character appears where the cursor was, and then the cursor moves one
+space to the right. If you mistype a character, you can use your
+erase character to back up and delete the mistyped character.
+
+Sometimes you may mistype a character, and
+not notice the error until you have typed several other characters. In
+that case, you can type @kbd{C-b} to move the cursor to the left, and then
+correct your mistake. Afterwards, you can move the cursor to the right
+with @kbd{C-f}.
+
+When you add text in the middle of a line, you will notice that characters
+to the right of the cursor are `pushed over' to make room for the text
+that you have inserted. Likewise, when you delete text behind the cursor,
+characters to the right of the cursor are `pulled back' to fill in the
+blank space created by the removal of the text. A list of the bare
+essentials for editing the text of an input line follows.
+
+@table @asis
+@item @kbd{C-b}
+Move back one character.
+@item @kbd{C-f}
+Move forward one character.
+@item @key{DEL} or @key{Backspace}
+Delete the character to the left of the cursor.
+@item @kbd{C-d}
+Delete the character underneath the cursor.
+@item @w{Printing characters}
+Insert the character into the line at the cursor.
+@item @kbd{C-_} or @kbd{C-x C-u}
+Undo the last editing command. You can undo all the way back to an
+empty line.
+@end table
+
+@noindent
+(Depending on your configuration, the @key{Backspace} key be set to
+delete the character to the left of the cursor and the @key{DEL} key set
+to delete the character underneath the cursor, like @kbd{C-d}, rather
+than the character to the left of the cursor.)
+
+@node Readline Movement Commands
+@subsection Readline Movement Commands
+
+
+The above table describes the most basic keystrokes that you need
+in order to do editing of the input line. For your convenience, many
+other commands have been added in addition to @kbd{C-b}, @kbd{C-f},
+@kbd{C-d}, and @key{DEL}. Here are some commands for moving more rapidly
+about the line.
+
+@table @kbd
+@item C-a
+Move to the start of the line.
+@item C-e
+Move to the end of the line.
+@item M-f
+Move forward a word, where a word is composed of letters and digits.
+@item M-b
+Move backward a word.
+@item C-l
+Clear the screen, reprinting the current line at the top.
+@end table
+
+Notice how @kbd{C-f} moves forward a character, while @kbd{M-f} moves
+forward a word. It is a loose convention that control keystrokes
+operate on characters while meta keystrokes operate on words.
+
+@node Readline Killing Commands
+@subsection Readline Killing Commands
+
+@cindex killing text
+@cindex yanking text
+
+@dfn{Killing} text means to delete the text from the line, but to save
+it away for later use, usually by @dfn{yanking} (re-inserting)
+it back into the line.
+(`Cut' and `paste' are more recent jargon for `kill' and `yank'.)
+
+If the description for a command says that it `kills' text, then you can
+be sure that you can get the text back in a different (or the same)
+place later.
+
+When you use a kill command, the text is saved in a @dfn{kill-ring}.
+Any number of consecutive kills save all of the killed text together, so
+that when you yank it back, you get it all. The kill
+ring is not line specific; the text that you killed on a previously
+typed line is available to be yanked back later, when you are typing
+another line.
+@cindex kill ring
+
+Here is the list of commands for killing text.
+
+@table @kbd
+@item C-k
+Kill the text from the current cursor position to the end of the line.
+
+@item M-d
+Kill from the cursor to the end of the current word, or, if between
+words, to the end of the next word.
+Word boundaries are the same as those used by @kbd{M-f}.
+
+@item M-@key{DEL}
+Kill from the cursor the start of the current word, or, if between
+words, to the start of the previous word.
+Word boundaries are the same as those used by @kbd{M-b}.
+
+@item C-w
+Kill from the cursor to the previous whitespace. This is different than
+@kbd{M-@key{DEL}} because the word boundaries differ.
+
+@end table
+
+Here is how to @dfn{yank} the text back into the line. Yanking
+means to copy the most-recently-killed text from the kill buffer.
+
+@table @kbd
+@item C-y
+Yank the most recently killed text back into the buffer at the cursor.
+
+@item M-y
+Rotate the kill-ring, and yank the new top. You can only do this if
+the prior command is @kbd{C-y} or @kbd{M-y}.
+@end table
+
+@node Readline Arguments
+@subsection Readline Arguments
+
+You can pass numeric arguments to Readline commands. Sometimes the
+argument acts as a repeat count, other times it is the @i{sign} of the
+argument that is significant. If you pass a negative argument to a
+command which normally acts in a forward direction, that command will
+act in a backward direction. For example, to kill text back to the
+start of the line, you might type @samp{M-- C-k}.
+
+The general way to pass numeric arguments to a command is to type meta
+digits before the command. If the first `digit' typed is a minus
+sign (@samp{-}), then the sign of the argument will be negative. Once
+you have typed one meta digit to get the argument started, you can type
+the remainder of the digits, and then the command. For example, to give
+the @kbd{C-d} command an argument of 10, you could type @samp{M-1 0 C-d},
+which will delete the next ten characters on the input line.
+
+@node Searching
+@subsection Searching for Commands in the History
+
+Readline provides commands for searching through the command history
+@ifset BashFeatures
+(@pxref{Bash History Facilities})
+@end ifset
+for lines containing a specified string.
+There are two search modes: @dfn{incremental} and @dfn{non-incremental}.
+
+Incremental searches begin before the user has finished typing the
+search string.
+As each character of the search string is typed, Readline displays
+the next entry from the history matching the string typed so far.
+An incremental search requires only as many characters as needed to
+find the desired history entry.
+To search backward in the history for a particular string, type
+@kbd{C-r}. Typing @kbd{C-s} searches forward through the history.
+The characters present in the value of the @code{isearch-terminators} variable
+are used to terminate an incremental search.
+If that variable has not been assigned a value, the @key{ESC} and
+@kbd{C-J} characters will terminate an incremental search.
+@kbd{C-g} will abort an incremental search and restore the original line.
+When the search is terminated, the history entry containing the
+search string becomes the current line.
+
+To find other matching entries in the history list, type @kbd{C-r} or
+@kbd{C-s} as appropriate.
+This will search backward or forward in the history for the next
+entry matching the search string typed so far.
+Any other key sequence bound to a Readline command will terminate
+the search and execute that command.
+For instance, a @key{RET} will terminate the search and accept
+the line, thereby executing the command from the history list.
+A movement command will terminate the search, make the last line found
+the current line, and begin editing.
+
+Readline remembers the last incremental search string. If two
+@kbd{C-r}s are typed without any intervening characters defining a new
+search string, any remembered search string is used.
+
+Non-incremental searches read the entire search string before starting
+to search for matching history lines. The search string may be
+typed by the user or be part of the contents of the current line.
+
+@node Readline Init File
+@section Readline Init File
+@cindex initialization file, readline
+
+Although the Readline library comes with a set of Emacs-like
+keybindings installed by default, it is possible to use a different set
+of keybindings.
+Any user can customize programs that use Readline by putting
+commands in an @dfn{inputrc} file, conventionally in his home directory.
+The name of this
+@ifset BashFeatures
+file is taken from the value of the shell variable @env{INPUTRC}. If
+@end ifset
+@ifclear BashFeatures
+file is taken from the value of the environment variable @env{INPUTRC}. If
+@end ifclear
+that variable is unset, the default is @file{~/.inputrc}. If that
+file does not exist or cannot be read, the ultimate default is
+@file{/etc/inputrc}.
+@ifset BashFeatures
+The @w{@code{bind}} builtin command can also be used to set Readline
+keybindings and variables.
+@xref{Bash Builtins}.
+@end ifset
+
+When a program which uses the Readline library starts up, the
+init file is read, and the key bindings are set.
+
+In addition, the @code{C-x C-r} command re-reads this init file, thus
+incorporating any changes that you might have made to it.

+
+@node Readline Init File Syntax
+@subsection Readline Init File Syntax
+
+There are only a few basic constructs allowed in the
+Readline init file. Blank lines are ignored.
+Lines beginning with a @samp{#} are comments.
+Lines beginning with a @samp{$} indicate conditional
+constructs (@pxref{Conditional Init Constructs}). Other lines
+denote variable settings and key bindings.
+
+@table @asis
+@item Variable Settings
+You can modify the run-time behavior of Readline by
+altering the values of variables in Readline
+using the @code{set} command within the init file.
+The syntax is simple:
+
+@example
+set @var{variable} @var{value}
+@end example
+
+@noindent
+Here, for example, is how to
+change from the default Emacs-like key binding to use
+@code{vi} line editing commands:
+
+@example
+set editing-mode vi
+@end example
+
+Variable names and values, where appropriate, are recognized without regard
+to case. Unrecognized variable names are ignored.
+
+Boolean variables (those that can be set to on or off) are set to on if
+the value is null or empty, @var{on} (case-insensitive), or 1. Any other
+value results in the variable being set to off.
+
+@ifset BashFeatures
+The @w{@code{bind -V}} command lists the current Readline variable names
+and values. @xref{Bash Builtins}.
+@end ifset
+
+A great deal of run-time behavior is changeable with the following
+variables.
+
+@cindex variables, readline
+@table @code
+
+@item bell-style
+@vindex bell-style
+Controls what happens when Readline wants to ring the terminal bell.
+If set to @samp{none}, Readline never rings the bell. If set to
+@samp{visible}, Readline uses a visible bell if one is available.
+If set to @samp{audible} (the default), Readline attempts to ring
+the terminal's bell.
+
+@item bind-tty-special-chars
+@vindex bind-tty-special-chars
+If set to @samp{on} (the default), Readline attempts to bind the control
+characters treated specially by the kernel's terminal driver to their
+Readline equivalents.
+
+@item blink-matching-paren
+@vindex blink-matching-paren
+If set to @samp{on}, Readline attempts to briefly move the cursor to an
+opening parenthesis when a closing parenthesis is inserted. The default
+is @samp{off}.
+
+@item colored-completion-prefix
+@vindex colored-completion-prefix
+If set to @samp{on}, when listing completions, Readline displays the
+common prefix of the set of possible completions using a different color.
+The color definitions are taken from the value of the @env{LS_COLORS}
+environment variable.
+The default is @samp{off}.
+
+@item colored-stats
+@vindex colored-stats
+If set to @samp{on}, Readline displays possible completions using different
+colors to indicate their file type.
+The color definitions are taken from the value of the @env{LS_COLORS}
+environment variable.
+The default is @samp{off}.
+
+@item comment-begin
+@vindex comment-begin
+The string to insert at the beginning of the line when the
+@code{insert-comment} command is executed. The default value
+is @code{"#"}.
+
+@item completion-display-width
+@vindex completion-display-width
+The number of screen columns used to display possible matches
+when performing completion.
+The value is ignored if it is less than 0 or greater than the terminal
+screen width.
+A value of 0 will cause matches to be displayed one per line.
+The default value is -1.
+
+@item completion-ignore-case
+@vindex completion-ignore-case
+If set to @samp{on}, Readline performs filename matching and completion
+in a case-insensitive fashion.
+The default value is @samp{off}.
+
+@item completion-map-case
+@vindex completion-map-case
+If set to @samp{on}, and @var{completion-ignore-case} is enabled, Readline
+treats hyphens (@samp{-}) and underscores (@samp{_}) as equivalent when
+performing case-insensitive filename matching and completion.
+The default value is @samp{off}.
+
+@item completion-prefix-display-length
+@vindex completion-prefix-display-length
+The length in characters of the common prefix of a list of possible
+completions that is displayed without modification. When set to a
+value greater than zero, common prefixes longer than this value are
+replaced with an ellipsis when displaying possible completions.
+
+@item completion-query-items
+@vindex completion-query-items
+The number of possible completions that determines when the user is
+asked whether the list of possibilities should be displayed.
+If the number of possible completions is greater than or equal to this value,
+Readline will ask whether or not the user wishes to view them;
+otherwise, they are simply listed.
+This variable must be set to an integer value greater than or equal to 0.
+A negative value means Readline should never ask.
+The default limit is @code{100}.
+
+@item convert-meta
+@vindex convert-meta
+If set to @samp{on}, Readline will convert characters with the
+eighth bit set to an @sc{ascii} key sequence by stripping the eighth
+bit and prefixing an @key{ESC} character, converting them to a
+meta-prefixed key sequence. The default value is @samp{on}, but
+will be set to @samp{off} if the locale is one that contains
+eight-bit characters.
+
+@item disable-completion
+@vindex disable-completion
+If set to @samp{On}, Readline will inhibit word completion.
+Completion characters will be inserted into the line as if they had
+been mapped to @code{self-insert}. The default is @samp{off}.
+
+@item echo-control-characters
+@vindex echo-control-characters
+When set to @samp{on}, on operating systems that indicate they support it,
+readline echoes a character corresponding to a signal generated from the
+keyboard. The default is @samp{on}.
+
+@item editing-mode
+@vindex editing-mode
+The @code{editing-mode} variable controls which default set of
+key bindings is used. By default, Readline starts up in Emacs editing
+mode, where the keystrokes are most similar to Emacs. This variable can be
+set to either @samp{emacs} or @samp{vi}.
+
+@item emacs-mode-string
+@vindex emacs-mode-string
+If the @var{show-mode-in-prompt} variable is enabled,
+this string is displayed immediately before the last line of the primary
+prompt when emacs editing mode is active. The value is expanded like a
+key binding, so the standard set of meta- and control prefixes and
+backslash escape sequences is available.
+Use the @samp{\1} and @samp{\2} escapes to begin and end sequences of
+non-printing characters, which can be used to embed a terminal control
+sequence into the mode string.
+The default is @samp{@@}.
+
+@item enable-bracketed-paste
+@vindex enable-bracketed-paste
+When set to @samp{On}, Readline will configure the terminal in a way
+that will enable it to insert each paste into the editing buffer as a
+single string of characters, instead of treating each character as if
+it had been read from the keyboard. This can prevent pasted characters
+from being interpreted as editing commands. The default is @samp{On}.
+
+@item enable-keypad
+@vindex enable-keypad
+When set to @samp{on}, Readline will try to enable the application
+keypad when it is called. Some systems need this to enable the
+arrow keys. The default is @samp{off}.
+
+@item enable-meta-key
+When set to @samp{on}, Readline will try to enable any meta modifier
+key the terminal claims to support when it is called. On many terminals,
+the meta key is used to send eight-bit characters.
+The default is @samp{on}.
+
+@item expand-tilde
+@vindex expand-tilde
+If set to @samp{on}, tilde expansion is performed when Readline
+attempts word completion. The default is @samp{off}.
+
+@item history-preserve-point
+@vindex history-preserve-point
+If set to @samp{on}, the history code attempts to place the point (the
+current cursor position) at the
+same location on each history line retrieved with @code{previous-history}
+or @code{next-history}. The default is @samp{off}.
+
+@item history-size
+@vindex history-size
+Set the maximum number of history entries saved in the history list.
+If set to zero, any existing history entries are deleted and no new entries
+are saved.
+If set to a value less than zero, the number of history entries is not
+limited.
+By default, the number of history entries is not limited.
+If an attempt is made to set @var{history-size} to a non-numeric value,
+the maximum number of history entries will be set to 500.
+
+@item horizontal-scroll-mode
+@vindex horizontal-scroll-mode
+This variable can be set to either @samp{on} or @samp{off}. Setting it
+to @samp{on} means that the text of the lines being edited will scroll
+horizontally on a single screen line when they are longer than the width
+of the screen, instead of wrapping onto a new screen line.
+This variable is automatically set to @samp{on} for terminals of height 1.
+By default, this variable is set to @samp{off}.
+
+@item input-meta
+@vindex input-meta
+@vindex meta-flag
+If set to @samp{on}, Readline will enable eight-bit input (it
+will not clear the eighth bit in the characters it reads),
+regardless of what the terminal claims it can support. The
+default value is @samp{off}, but Readline will set it to @samp{on} if the 
+locale contains eight-bit characters.
+The name @code{meta-flag} is a synonym for this variable.
+
+@item isearch-terminators
+@vindex isearch-terminators
+The string of characters that should terminate an incremental search without
+subsequently executing the character as a command (@pxref{Searching}).
+If this variable has not been given a value, the characters @key{ESC} and
+@kbd{C-J} will terminate an incremental search.
+
+@item keymap
+@vindex keymap
+Sets Readline's idea of the current keymap for key binding commands.
+Built-in @code{keymap} names are
+@code{emacs},
+@code{emacs-standard},
+@code{emacs-meta},
+@code{emacs-ctlx},
+@code{vi},
+@code{vi-move},
+@code{vi-command}, and
+@code{vi-insert}.
+@code{vi} is equivalent to @code{vi-command} (@code{vi-move} is also a
+synonym); @code{emacs} is equivalent to @code{emacs-standard}.
+Applications may add additional names.
+The default value is @code{emacs}.
+The value of the @code{editing-mode} variable also affects the
+default keymap.
+
+@item keyseq-timeout
+Specifies the duration Readline will wait for a character when reading an
+ambiguous key sequence (one that can form a complete key sequence using
+the input read so far, or can take additional input to complete a longer
+key sequence).
+If no input is received within the timeout, Readline will use the shorter
+but complete key sequence.
+Readline uses this value to determine whether or not input is
+available on the current input source (@code{rl_instream} by default).
+The value is specified in milliseconds, so a value of 1000 means that
+Readline will wait one second for additional input.
+If this variable is set to a value less than or equal to zero, or to a
+non-numeric value, Readline will wait until another key is pressed to
+decide which key sequence to complete.
+The default value is @code{500}.
+
+@item mark-directories
+If set to @samp{on}, completed directory names have a slash
+appended. The default is @samp{on}.
+
+@item mark-modified-lines
+@vindex mark-modified-lines
+This variable, when set to @samp{on}, causes Readline to display an
+asterisk (@samp{*}) at the start of history lines which have been modified.
+This variable is @samp{off} by default.
+
+@item mark-symlinked-directories
+@vindex mark-symlinked-directories
+If set to @samp{on}, completed names which are symbolic links
+to directories have a slash appended (subject to the value of
+@code{mark-directories}).
+The default is @samp{off}.
+
+@item match-hidden-files
+@vindex match-hidden-files
+This variable, when set to @samp{on}, causes Readline to match files whose
+names begin with a @samp{.} (hidden files) when performing filename
+completion.
+If set to @samp{off}, the leading @samp{.} must be
+supplied by the user in the filename to be completed.
+This variable is @samp{on} by default.
+
+@item menu-complete-display-prefix
+@vindex menu-complete-display-prefix
+If set to @samp{on}, menu completion displays the common prefix of the
+list of possible completions (which may be empty) before cycling through
+the list. The default is @samp{off}.
+
+@item output-meta
+@vindex output-meta
+If set to @samp{on}, Readline will display characters with the
+eighth bit set directly rather than as a meta-prefixed escape
+sequence.
+The default is @samp{off}, but Readline will set it to @samp{on} if the
+locale contains eight-bit characters.
+
+@item page-completions
+@vindex page-completions
+If set to @samp{on}, Readline uses an internal @code{more}-like pager
+to display a screenful of possible completions at a time.
+This variable is @samp{on} by default.
+
+@item print-completions-horizontally
+If set to @samp{on}, Readline will display completions with matches
+sorted horizontally in alphabetical order, rather than down the screen.
+The default is @samp{off}.
+
+@item revert-all-at-newline
+@vindex revert-all-at-newline
+If set to @samp{on}, Readline will undo all changes to history lines
+before returning when @code{accept-line} is executed. By default,
+history lines may be modified and retain individual undo lists across
+calls to @code{readline}. The default is @samp{off}.
+
+@item show-all-if-ambiguous
+@vindex show-all-if-ambiguous
+This alters the default behavior of the completion functions. If
+set to @samp{on}, 
+words which have more than one possible completion cause the
+matches to be listed immediately instead of ringing the bell.
+The default value is @samp{off}.
+
+@item show-all-if-unmodified
+@vindex show-all-if-unmodified
+This alters the default behavior of the completion functions in
+a fashion similar to @var{show-all-if-ambiguous}.
+If set to @samp{on}, 
+words which have more than one possible completion without any
+possible partial completion (the possible completions don't share
+a common prefix) cause the matches to be listed immediately instead
+of ringing the bell.
+The default value is @samp{off}.
+
+@item show-mode-in-prompt
+@vindex show-mode-in-prompt
+If set to @samp{on}, add a string to the beginning of the prompt
+indicating the editing mode: emacs, vi command, or vi insertion.
+The mode strings are user-settable (e.g., @var{emacs-mode-string}).
+The default value is @samp{off}.
+
+@item skip-completed-text
+@vindex skip-completed-text
+If set to @samp{on}, this alters the default completion behavior when
+inserting a single match into the line. It's only active when
+performing completion in the middle of a word. If enabled, readline
+does not insert characters from the completion that match characters
+after point in the word being completed, so portions of the word
+following the cursor are not duplicated.
+For instance, if this is enabled, attempting completion when the cursor
+is after the @samp{e} in @samp{Makefile} will result in @samp{Makefile}
+rather than @samp{Makefilefile}, assuming there is a single possible
+completion.
+The default value is @samp{off}.
+
+@item vi-cmd-mode-string
+@vindex vi-cmd-mode-string
+If the @var{show-mode-in-prompt} variable is enabled,
+this string is displayed immediately before the last line of the primary
+prompt when vi editing mode is active and in command mode.
+The value is expanded like a
+key binding, so the standard set of meta- and control prefixes and
+backslash escape sequences is available.
+Use the @samp{\1} and @samp{\2} escapes to begin and end sequences of
+non-printing characters, which can be used to embed a terminal control
+sequence into the mode string.
+The default is @samp{(cmd)}.
+
+@item vi-ins-mode-string
+@vindex vi-ins-mode-string
+If the @var{show-mode-in-prompt} variable is enabled,
+this string is displayed immediately before the last line of the primary
+prompt when vi editing mode is active and in insertion mode.
+The value is expanded like a
+key binding, so the standard set of meta- and control prefixes and
+backslash escape sequences is available.
+Use the @samp{\1} and @samp{\2} escapes to begin and end sequences of
+non-printing characters, which can be used to embed a terminal control
+sequence into the mode string.
+The default is @samp{(ins)}.
+
+@item visible-stats
+@vindex visible-stats
+If set to @samp{on}, a character denoting a file's type
+is appended to the filename when listing possible
+completions. The default is @samp{off}.
+
+@end table
+
+@item Key Bindings
+The syntax for controlling key bindings in the init file is
+simple. First you need to find the name of the command that you
+want to change. The following sections contain tables of the command
+name, the default keybinding, if any, and a short description of what
+the command does.
+
+Once you know the name of the command, simply place on a line
+in the init file the name of the key
+you wish to bind the command to, a colon, and then the name of the
+command.
+There can be no space between the key name and the colon -- that will be
+interpreted as part of the key name.
+The name of the key can be expressed in different ways, depending on
+what you find most comfortable.
+
+In addition to command names, readline allows keys to be bound
+to a string that is inserted when the key is pressed (a @var{macro}).
+
+@ifset BashFeatures
+The @w{@code{bind -p}} command displays Readline function names and
+bindings in a format that can put directly into an initialization file.
+@xref{Bash Builtins}.
+@end ifset
+
+@table @asis
+@item @w{@var{keyname}: @var{function-name} or @var{macro}}
+@var{keyname} is the name of a key spelled out in English. For example:
+@example
+Control-u: universal-argument
+Meta-Rubout: backward-kill-word
+Control-o: "> output"
+@end example
+
+In the example above, @kbd{C-u} is bound to the function
+@code{universal-argument},
+@kbd{M-DEL} is bound to the function @code{backward-kill-word}, and
+@kbd{C-o} is bound to run the macro
+expressed on the right hand side (that is, to insert the text
+@samp{> output} into the line).
+
+A number of symbolic character names are recognized while
+processing this key binding syntax:
+@var{DEL},
+@var{ESC},
+@var{ESCAPE},
+@var{LFD},
+@var{NEWLINE},
+@var{RET},
+@var{RETURN},
+@var{RUBOUT},
+@var{SPACE},
+@var{SPC},
+and
+@var{TAB}.
+
+@item @w{"@var{keyseq}": @var{function-name} or @var{macro}}
+@var{keyseq} differs from @var{keyname} above in that strings
+denoting an entire key sequence can be specified, by placing
+the key sequence in double quotes. Some @sc{gnu} Emacs style key
+escapes can be used, as in the following example, but the
+special character names are not recognized.
+
+@example
+"\C-u": universal-argument
+"\C-x\C-r": re-read-init-file
+"\e11~": "Function Key 1"
+@end example
+
+In the above example, @kbd{C-u} is again bound to the function
+@code{universal-argument} (just as it was in the first example),
+@samp{@kbd{C-x} @kbd{C-r}} is bound to the function @code{re-read-init-file},
+and @samp{@key{ESC} @key{} @key{1} @key{1} @key{~}} is bound to insert
+the text @samp{Function Key 1}.
+
+@end table
+
+The following @sc{gnu} Emacs style escape sequences are available when
+specifying key sequences:
+
+@table @code
+@item @kbd{\C-}
+control prefix
+@item @kbd{\M-}
+meta prefix
+@item @kbd{\e}
+an escape character
+@item @kbd{\\}
+backslash
+@item @kbd{\"}
+@key{"}, a double quotation mark
+@item @kbd{\'}
+@key{'}, a single quote or apostrophe
+@end table
+
+In addition to the @sc{gnu} Emacs style escape sequences, a second
+set of backslash escapes is available:
+
+@table @code
+@item \a
+alert (bell)
+@item \b
+backspace
+@item \d
+delete
+@item \f
+form feed
+@item \n
+newline
+@item \r
+carriage return
+@item \t
+horizontal tab
+@item \v
+vertical tab
+@item \@var{nnn}
+the eight-bit character whose value is the octal value @var{nnn}
+(one to three digits)
+@item \x@var{HH}
+the eight-bit character whose value is the hexadecimal value @var{HH}
+(one or two hex digits)
+@end table
+
+When entering the text of a macro, single or double quotes must
+be used to indicate a macro definition.
+Unquoted text is assumed to be a function name.
+In the macro body, the backslash escapes described above are expanded.
+Backslash will quote any other character in the macro text,
+including @samp{"} and @samp{'}.
+For example, the following binding will make @samp{@kbd{C-x} \}
+insert a single @samp{\} into the line:
+@example
+"\C-x\\": "\\"
+@end example
+
+@end table
+
+@node Conditional Init Constructs
+@subsection Conditional Init Constructs
+
+Readline implements a facility similar in spirit to the conditional
+compilation features of the C preprocessor which allows key
+bindings and variable settings to be performed as the result
+of tests. There are four parser directives used.
+
+@table @code
+@item $if
+The @code{$if} construct allows bindings to be made based on the
+editing mode, the terminal being used, or the application using
+Readline. The text of the test, after any comparison operator,
+extends to the end of the line;
+unless otherwise noted, no characters are required to isolate it.
+
+@table @code
+@item mode
+The @code{mode=} form of the @code{$if} directive is used to test
+whether Readline is in @code{emacs} or @code{vi} mode.
+This may be used in conjunction
+with the @samp{set keymap} command, for instance, to set bindings in
+the @code{emacs-standard} and @code{emacs-ctlx} keymaps only if
+Readline is starting out in @code{emacs} mode.
+
+@item term
+The @code{term=} form may be used to include terminal-specific
+key bindings, perhaps to bind the key sequences output by the
+terminal's function keys. The word on the right side of the
+@samp{=} is tested against both the full name of the terminal and
+the portion of the terminal name before the first @samp{-}. This
+allows @code{sun} to match both @code{sun} and @code{sun-cmd},
+for instance.
+
+@item version
+The @code{version} test may be used to perform comparisons against
+specific Readline versions.
+The @code{version} expands to the current Readline version.
+The set of comparison operators includes
+@samp{=} (and @samp{==}), @samp{!=}, @samp{<=}, @samp{>=}, @samp{<},
+and @samp{>}.
+The version number supplied on the right side of the operator consists
+of a major version number, an optional decimal point, and an optional
+minor version (e.g., @samp{7.1}). If the minor version is omitted, it
+is assumed to be @samp{0}.
+The operator may be separated from the string @code{version} and
+from the version number argument by whitespace.
+The following example sets a variable if the Readline version being used
+is 7.0 or newer:
+@example
+$if version >= 7.0
+set show-mode-in-prompt on
+$endif
+@end example
+
+@item application
+The @var{application} construct is used to include
+application-specific settings. Each program using the Readline
+library sets the @var{application name}, and you can test for
+a particular value. 
+This could be used to bind key sequences to functions useful for
+a specific program. For instance, the following command adds a
+key sequence that quotes the current or previous word in Bash:
+@example

+
+@item variable
+The @var{variable} construct provides simple equality tests for Readline
+variables and values.
+The permitted comparison operators are @samp{=}, @samp{==}, and @samp{!=}.
+The variable name must be separated from the comparison operator by
+whitespace; the operator may be separated from the value on the right hand
+side by whitespace.
+Both string and boolean variables may be tested. Boolean variables must be
+tested against the values @var{on} and @var{off}.
+The following example is equivalent to the @code{mode=emacs} test described
+above:
+@example
+$if editing-mode == emacs
+set show-mode-in-prompt on
+$endif
+@end example
+@end table
+
+@item $endif
+This command, as seen in the previous example, terminates an
+@code{$if} command.
+
+@item $else
+Commands in this branch of the @code{$if} directive are executed if
+the test fails.
+
+@item $include
+This directive takes a single filename as an argument and reads commands
+and bindings from that file.
+For example, the following directive reads from @file{/etc/inputrc}:
+@example
+$include /etc/inputrc

+@code{add_history()}.
+If this line is a modified history line, the history line is restored
+to its original state.
+@end ifclear
+
+@item previous-history (C-p)
+Move `back' through the history list, fetching the previous command.
+
+@item next-history (C-n)
+Move `forward' through the history list, fetching the next command.
+
+@item beginning-of-history (M-<)
+Move to the first line in the history.
+
+@item end-of-history (M->)
+Move to the end of the input history, i.e., the line currently
+being entered.
+
+@item reverse-search-history (C-r)
+Search backward starting at the current line and moving `up' through
+the history as necessary. This is an incremental search.
+This command sets the region to the matched text and activates the mark.
+
+@item forward-search-history (C-s)
+Search forward starting at the current line and moving `down' through
+the history as necessary. This is an incremental search.
+This command sets the region to the matched text and activates the mark.
+
+@item non-incremental-reverse-search-history (M-p)
+Search backward starting at the current line and moving `up'
+through the history as necessary using a non-incremental search
+for a string supplied by the user.
+The search string may match anywhere in a history line.
+
+@item non-incremental-forward-search-history (M-n)
+Search forward starting at the current line and moving `down'
+through the history as necessary using a non-incremental search
+for a string supplied by the user.
+The search string may match anywhere in a history line.
+
+@item history-search-forward ()
+Search forward through the history for the string of characters
+between the start of the current line and the point.
+The search string must match at the beginning of a history line.
+This is a non-incremental search.
+By default, this command is unbound.
+
+@item history-search-backward ()
+Search backward through the history for the string of characters
+between the start of the current line and the point.
+The search string must match at the beginning of a history line.
+This is a non-incremental search.
+By default, this command is unbound.

+The search string may match anywhere in a history line.
+This is a non-incremental search.
+By default, this command is unbound.
+
+@item yank-nth-arg (M-C-y)
+Insert the first argument to the previous command (usually
+the second word on the previous line) at point.
+With an argument @var{n},
+insert the @var{n}th word from the previous command (the words
+in the previous command begin with word 0). A negative argument
+inserts the @var{n}th word from the end of the previous command.
+Once the argument @var{n} is computed, the argument is extracted
+as if the @samp{!@var{n}} history expansion had been specified.
+
+@item yank-last-arg (M-. or M-_)
+Insert last argument to the previous command (the last word of the
+previous history entry).
+With a numeric argument, behave exactly like @code{yank-nth-arg}.
+Successive calls to @code{yank-last-arg} move back through the history
+list, inserting the last word (or the word specified by the argument to
+the first call) of each line in turn.
+Any numeric argument supplied to these successive calls determines
+the direction to move through the history. A negative argument switches
+the direction through the history (back or forward).
+The history expansion facilities are used to extract the last argument,
+as if the @samp{!$} history expansion had been specified.
+
+@item operate-and-get-next (C-o)
+Accept the current line for return to the calling application as if a
+newline had been entered,
+and fetch the next line relative to the current line from the history

+of the current line.
+
+@end ftable
+
+@node Commands For Text
+@subsection Commands For Changing Text
+
+@ftable @code
+
+@item @i{end-of-file} (usually C-d)
+The character indicating end-of-file as set, for example, by
+@code{stty}. If this character is read when there are no characters
+on the line, and point is at the beginning of the line, Readline
+interprets it as the end of input and returns @sc{eof}.
+
+@item delete-char (C-d)
+Delete the character at point. If this function is bound to the
+same character as the tty @sc{eof} character, as @kbd{C-d}
+commonly is, see above for the effects.
+
+@item backward-delete-char (Rubout)
+Delete the character behind the cursor. A numeric argument means
+to kill the characters instead of deleting them.
+
+@item forward-backward-delete-char ()
+Delete the character under the cursor, unless the cursor is at the
+end of the line, in which case the character behind the cursor is
+deleted. By default, this is not bound to a key.
+
+@item quoted-insert (C-q or C-v)
+Add the next character typed to the line verbatim. This is
+how to insert key sequences like @kbd{C-q}, for example.
+
+@ifclear BashFeatures
+@item tab-insert (M-@key{TAB})
+Insert a tab character.
+@end ifclear
+
+@item self-insert (a, b, A, 1, !, @dots{})
+Insert yourself.
+
+@item bracketed-paste-begin ()
+This function is intended to be bound to the "bracketed paste" escape
+sequence sent by some terminals, and such a binding is assigned by default.
+It allows Readline to insert the pasted text as a single unit without treating
+each character as if it had been read from the keyboard. The characters
+are inserted as if each one was bound to @code{self-insert} instead of
+executing any editing commands.
+
+Bracketed paste sets the region (the characters between point and the mark)
+to the inserted text. It uses the concept of an @emph{active mark}: when the
+mark is active, Readline redisplay uses the terminal's standout mode to
+denote the region.
+
+@item transpose-chars (C-t)
+Drag the character before the cursor forward over
+the character at the cursor, moving the
+cursor forward as well. If the insertion point
+is at the end of the line, then this
+transposes the last two characters of the line.
+Negative arguments have no effect.
+
+@item transpose-words (M-t)
+Drag the word before point past the word after point,
+moving point past that word as well.
+If the insertion point is at the end of the line, this transposes
+the last two words on the line.
+
+@item upcase-word (M-u)
+Uppercase the current (or following) word. With a negative argument,
+uppercase the previous word, but do not move the cursor.
+
+@item downcase-word (M-l)
+Lowercase the current (or following) word. With a negative argument,
+lowercase the previous word, but do not move the cursor.
+
+@item capitalize-word (M-c)
+Capitalize the current (or following) word. With a negative argument,
+capitalize the previous word, but do not move the cursor.
+
+@item overwrite-mode ()
+Toggle overwrite mode. With an explicit positive numeric argument,
+switches to overwrite mode. With an explicit non-positive numeric
+argument, switches to insert mode. This command affects only
+@code{emacs} mode; @code{vi} mode does overwrite differently.
+Each call to @code{readline()} starts in insert mode.
+
+In overwrite mode, characters bound to @code{self-insert} replace
+the text at point rather than pushing the text to the right.
+Characters bound to @code{backward-delete-char} replace the character
+before point with a space.
+
+By default, this command is unbound.

+Kill backward from the cursor to the beginning of the current line.
+
+@item kill-whole-line ()
+Kill all characters on the current line, no matter where point is.
+By default, this is unbound.
+
+@item kill-word (M-d)
+Kill from point to the end of the current word, or if between
+words, to the end of the next word.
+Word boundaries are the same as @code{forward-word}.
+
+@item backward-kill-word (M-@key{DEL})

+@end ifset
+
+@item shell-transpose-words (M-C-t)
+Drag the word before point past the word after point,

+If the insertion point is at the end of the line, this transposes
+the last two words on the line.
+Word boundaries are the same as @code{shell-forward-word} and
+@code{shell-backward-word}.
+
+@item unix-word-rubout (C-w)
+Kill the word behind point, using white space as a word boundary.
+The killed text is saved on the kill-ring.
+
+@item unix-filename-rubout ()
+Kill the word behind point, using white space and the slash character
+as the word boundaries.
+The killed text is saved on the kill-ring.
+
+@item delete-horizontal-space ()
+Delete all spaces and tabs around point. By default, this is unbound.
+
+@item kill-region ()
+Kill the text in the current region.
+By default, this command is unbound.
+
+@item copy-region-as-kill ()
+Copy the text in the region to the kill buffer, so it can be yanked
+right away. By default, this command is unbound.
+
+@item copy-backward-word ()
+Copy the word before point to the kill buffer.
+The word boundaries are the same as @code{backward-word}.
+By default, this command is unbound.
+
+@item copy-forward-word ()
+Copy the word following point to the kill buffer.
+The word boundaries are the same as @code{forward-word}.
+By default, this command is unbound.
+
+@item yank (C-y)
+Yank the top of the kill ring into the buffer at point.
+
+@item yank-pop (M-y)
+Rotate the kill-ring, and yank the new top. You can only do this if
+the prior command is @code{yank} or @code{yank-pop}.

+@subsection Specifying Numeric Arguments
+@ftable @code
+
+@item digit-argument (@kbd{M-0}, @kbd{M-1}, @dots{} @kbd{M--})
+Add this digit to the argument already accumulating, or start a new
+argument. @kbd{M--} starts a negative argument.
+
+@item universal-argument ()
+This is another way to specify an argument.
+If this command is followed by one or more digits, optionally with a
+leading minus sign, those digits define the argument.
+If the command is followed by digits, executing @code{universal-argument}
+again ends the numeric argument, but is otherwise ignored.
+As a special case, if this command is immediately followed by a
+character that is neither a digit nor minus sign, the argument count
+for the next command is multiplied by four.
+The argument count is initially one, so executing this function the
+first time makes the argument count four, a second time makes the
+argument count sixteen, and so on.

+@samp{~}), hostname (if the text begins with @samp{@@}), or
+command (including aliases and functions) in turn. If none 
+of these produces a match, filename completion is attempted.
+@end ifset
+@ifclear BashFeatures
+The default is filename completion.
+@end ifclear
+
+@item possible-completions (M-?)
+List the possible completions of the text before point.
+When displaying completions, Readline sets the number of columns used
+for display to the value of @code{completion-display-width}, the value of
+the environment variable @env{COLUMNS}, or the screen width, in that order.
+
+@item insert-completions (M-*)
+Insert all completions of the text before point that would have
+been generated by @code{possible-completions}.
+
+@item menu-complete ()
+Similar to @code{complete}, but replaces the word to be completed
+with a single match from the list of possible completions.
+Repeated execution of @code{menu-complete} steps through the list
+of possible completions, inserting each match in turn.
+At the end of the list of completions, the bell is rung
+(subject to the setting of @code{bell-style})
+and the original text is restored.
+An argument of @var{n} moves @var{n} positions forward in the list
+of matches; a negative argument may be used to move backward
+through the list.
+This command is intended to be bound to @key{TAB}, but is unbound
+by default.
+
+@item menu-complete-backward ()
+Identical to @code{menu-complete}, but moves backward through the list
+of possible completions, as if @code{menu-complete} had been given a
+negative argument.
+
+@item delete-char-or-list ()
+Deletes the character under the cursor if not at the beginning or

+List the possible completions of the text before point,
+treating it as a hostname.
+
+@item complete-command (M-!)
+Attempt completion on the text before point, treating
+it as a command name. Command completion attempts to
+match the text against aliases, reserved words, shell
+functions, shell builtins, and finally executable filenames,
+in that order.
+
+@item possible-command-completions (C-x !)
+List the possible completions of the text before point,

+@node Programmable Completion
+@section Programmable Completion
+@cindex programmable completion
+
+When word completion is attempted for an argument to a command for
+which a completion specification (a @var{compspec}) has been defined
+using the @code{complete} builtin (@pxref{Programmable Completion Builtins}),
+the programmable completion facilities are invoked. 
+
+First, the command name is identified.
+If a compspec has been defined for that command, the
+compspec is used to generate the list of possible completions for the word.
+If the command word is the empty string (completion attempted at the
+beginning of an empty line), any compspec defined with
+the @option{-E} option to @code{complete} is used.
+If the command word is a full pathname, a compspec for the full
+pathname is searched for first.
+If no compspec is found for the full pathname, an attempt is made to
+find a compspec for the portion following the final slash.
+If those searches do not result in a compspec, any compspec defined with
+the @option{-D} option to @code{complete} is used as the default.
+If there is no default compspec, Bash attempts alias expansion
+on the command word as a final resort, and attempts to find a compspec
+for the command word from any successful expansion 
+
+Once a compspec has been found, it is used to generate the list of
+matching words.
+If a compspec is not found, the default Bash completion
+described above (@pxref{Commands For Completion}) is performed.
+
+First, the actions specified by the compspec are used.
+Only matches which are prefixed by the word being completed are
+returned.
+When the @option{-f} or @option{-d} option is used for filename or
+directory name completion, the shell variable @env{FIGNORE} is
+used to filter the matches.
+@xref{Bash Variables}, for a description of @env{FIGNORE}.
+
+Any completions specified by a filename expansion pattern to the
+@option{-G} option are generated next.
+The words generated by the pattern need not match the word being completed.
+The @env{GLOBIGNORE} shell variable is not used to filter the matches,
+but the @env{FIGNORE} shell variable is used.
+
+Next, the string specified as the argument to the @option{-W} option
+is considered.
+The string is first split using the characters in the @env{IFS}
+special variable as delimiters.
+Shell quoting is honored within the string, in order to provide a
+mechanism for the words to contain shell metacharacters or characters
+in the value of @env{IFS}.
+Each word is then expanded using
+brace expansion, tilde expansion, parameter and variable expansion,
+command substitution, and arithmetic expansion,
+as described above (@pxref{Shell Expansions}).
+The results are split using the rules described above
+(@pxref{Word Splitting}).
+The results of the expansion are prefix-matched against the word being
+completed, and the matching words become the possible completions.
+
+After these matches have been generated, any shell function or command
+specified with the @option{-F} and @option{-C} options is invoked.
+When the command or function is invoked, the @env{COMP_LINE},
+@env{COMP_POINT}, @env{COMP_KEY}, and @env{COMP_TYPE} variables are
+assigned values as described above (@pxref{Bash Variables}).
+If a shell function is being invoked, the @env{COMP_WORDS} and
+@env{COMP_CWORD} variables are also set.
+When the function or command is invoked, the first argument ($1) is the
+name of the command whose arguments are being completed, the
+second argument ($2) is the word being completed, and the third argument
+($3) is the word preceding the word being completed on the current command
+line.
+No filtering of the generated completions against the word being completed
+is performed; the function or command has complete freedom in generating
+the matches.
+
+Any function specified with @option{-F} is invoked first.
+The function may use any of the shell facilities, including the
+@code{compgen} and @code{compopt} builtins described below
+(@pxref{Programmable Completion Builtins}), to generate the matches.
+It must put the possible completions in the @env{COMPREPLY} array
+variable, one per array element.
+
+Next, any command specified with the @option{-C} option is invoked
+in an environment equivalent to command substitution.
+It should print a list of completions, one per line, to
+the standard output.
+Backslash may be used to escape a newline, if necessary.
+
+After all of the possible completions are generated, any filter
+specified with the @option{-X} option is applied to the list.
+The filter is a pattern as used for pathname expansion; a @samp{&}
+in the pattern is replaced with the text of the word being completed.
+A literal @samp{&} may be escaped with a backslash; the backslash
+is removed before attempting a match.
+Any completion that matches the pattern will be removed from the list.
+A leading @samp{!} negates the pattern; in this case any completion
+not matching the pattern will be removed.
+If the @code{nocasematch} shell option
+(see the description of @code{shopt} in @ref{The Shopt Builtin})
+is enabled, the match is performed without regard to the case
+of alphabetic characters.
+
+Finally, any prefix and suffix specified with the @option{-P} and @option{-S}
+options are added to each member of the completion list, and the result is
+returned to the Readline completion code as the list of possible
+completions.
+
+If the previously-applied actions do not generate any matches, and the
+@option{-o dirnames} option was supplied to @code{complete} when the
+compspec was defined, directory name completion is attempted. 
+
+If the @option{-o plusdirs} option was supplied to @code{complete} when
+the compspec was defined, directory name completion is attempted and any
+matches are added to the results of the other actions.
+
+By default, if a compspec is found, whatever it generates is returned to
+the completion code as the full set of possible completions.
+The default Bash completions are not attempted, and the Readline default
+of filename completion is disabled.
+If the @option{-o bashdefault} option was supplied to @code{complete} when
+the compspec was defined, the default Bash completions are attempted
+if the compspec generates no matches.
+If the @option{-o default} option was supplied to @code{complete} when the
+compspec was defined, Readline's default completion will be performed
+if the compspec (and, if attempted, the default Bash completions)
+generate no matches.
+
+When a compspec indicates that directory name completion is desired,
+the programmable completion functions force Readline to append a slash
+to completed names which are symbolic links to directories, subject to
+the value of the @var{mark-directories} Readline variable, regardless
+of the setting of the @var{mark-symlinked-directories} Readline variable.
+
+There is some support for dynamically modifying completions. This is
+most useful when used in combination with a default completion specified
+with @option{-D}. It's possible for shell functions executed as completion
+handlers to indicate that completion should be retried by returning an
+exit status of 124. If a shell function returns 124, and changes
+the compspec associated with the command on which completion is being
+attempted (supplied as the first argument when the function is executed),
+programmable completion restarts from the beginning, with an
+attempt to find a new compspec for that command. This allows a set of
+completions to be built dynamically as completion is attempted, rather than
+being loaded all at once.
+
+For instance, assuming that there is a library of compspecs, each kept in a
+file corresponding to the name of the command, the following default
+completion function would load completions dynamically:
+
+@example
+_completion_loader()
+@{
+ . "/etc/bash_completion.d/$1.sh" >/dev/null 2>&1 && return 124
+@}
+complete -D -F _completion_loader -o bashdefault -o default
+@end example
+
+@node Programmable Completion Builtins
+@section Programmable Completion Builtins

+@item compgen
+@btindex compgen
+@example
+@code{compgen @var{option} @var{word}}

+@code{complete}
+builtin with the exception of @option{-p} and @option{-r}, and write
+the matches to the standard output.
+When using the @option{-F} or @option{-C} options, the various shell variables
+set by the programmable completion facilities, while available, will not
+have useful values.
+
+The matches will be generated in the same way as if the programmable
+completion code had generated them directly from a completion specification
+with the same flags.
+If @var{word} is specified, only those completions matching @var{word}
+will be displayed.
+
+The return value is true unless an invalid option is supplied, or no

+@end example
+
+Specify how arguments to each @var{name} should be completed.
+If the @option{-p} option is supplied, or if no options are supplied, existing
+completion specifications are printed in a way that allows them to be
+reused as input.
+The @option{-r} option removes a completion specification for
+each @var{name}, or, if no @var{name}s are supplied, all
+completion specifications.
+The @option{-D} option indicates that other supplied options and actions should
+apply to the ``default'' command completion; that is, completion attempted
+on a command for which no completion has previously been defined.
+The @option{-E} option indicates that other supplied options and actions should
+apply to ``empty'' command completion; that is, completion attempted on a 
+blank line.
+The @option{-I} option indicates that other supplied options and actions should
+apply to completion on the initial non-assignment word on the line, or after a
+command delimiter such as @samp{;} or @samp{|}, which is usually command
+name completion.
+If multiple options are supplied, the @option{-D} option takes precedence
+over @option{-E}, and both take precedence over @option{-I}.
+If any of @option{-D}, @option{-E}, or @option{-I} are supplied, any other
+@var{name} arguments are ignored; these completions only apply to the case
+specified by the option.
+
+The process of applying these completion specifications when word completion
+is attempted is described above (@pxref{Programmable Completion}).
+
+Other options, if specified, have the following meanings.
+The arguments to the @option{-G}, @option{-W}, and @option{-X} options
+(and, if necessary, the @option{-P} and @option{-S} options)
+should be quoted to protect them from expansion before the
+@code{complete} builtin is invoked.

+@node A Programmable Completion Example
+@section A Programmable Completion Example
+
+The most common way to obtain additional completion functionality beyond
+the default actions @code{complete} and @code{compgen} provide is to use
+a shell function and bind it to a particular command using @code{complete -F}.
+
+The following function provides completions for the @code{cd} builtin.
+It is a reasonably good example of what shell functions must do when
+used for completion. This function uses the word passed as @code{$2}
+to determine the directory name to complete. You can also use the
+@code{COMP_WORDS} array variable; the current word is indexed by the
+@code{COMP_CWORD} variable.
+
+The function relies on the @code{complete} and @code{compgen} builtins
+to do much of the work, adding only the things that the Bash @code{cd}
+does beyond accepting basic directory names:
+tilde expansion (@pxref{Tilde Expansion}),
+searching directories in @var{$CDPATH}, which is described above
+(@pxref{Bourne Shell Builtins}),
+and basic support for the @code{cdable_vars} shell option
+(@pxref{The Shopt Builtin}).
+@code{_comp_cd} modifies the value of @var{IFS} so that it contains only
+a newline to accommodate file names containing spaces and tabs --
+@code{compgen} prints the possible completions it generates one per line.
+
+Possible completions go into the @var{COMPREPLY} array variable, one
+completion per array element. The programmable completion system retrieves
+the completions from there when the function returns.
+
+@example
+# A completion function for the cd builtin
+# based on the cd completion function from the bash_completion package
+_comp_cd()
+@{
+ local IFS=$' \t\n' # normalize IFS
+ local cur _skipdot _cdpath
+ local i j k
+
+ # Tilde expansion, which also expands tilde to full pathname
+ case "$2" in
+ \~*) eval cur="$2" ;;
+ *) cur=$2 ;;
+ esac
+
+ # no cdpath or absolute pathname -- straight directory completion
+ if -z "$@{CDPATH:-@}" || "$cur" == @@(./*|../*|/*) ; then
+ # compgen prints paths one per line; could also use while loop
+ IFS=$'\n'
+ COMPREPLY=( $(compgen -d -- "$cur") )
+ IFS=$' \t\n'
+ # CDPATH+directories in the current directory if not in CDPATH
+ else
+ IFS=$'\n'
+ _skipdot=false
+ # preprocess CDPATH to convert null directory names to .
+ _cdpath=$@{CDPATH/#:/.:@}
+ _cdpath=$@{_cdpath//::/:.:@}
+ _cdpath=$@{_cdpath/%:/:.@}
+ for i in $@{_cdpath//:/$'\n'@}; do
+ if $i -ef . ; then _skipdot=true; fi
+ k="$@{#COMPREPLY@@@}"
+ for j in $( compgen -d -- "$i/$cur" ); do
+ COMPREPLYk++=$@{j#$i/@} # cut off directory
+ done
+ done
+ $_skipdot || COMPREPLY+=( $(compgen -d -- "$cur") )
+ IFS=$' \t\n'
+ fi
+
+ # variable names if appropriate shell option set and no completions
+ if shopt -q cdable_vars && $@{#COMPREPLY@@@} -eq 0 ; then
+ COMPREPLY=( $(compgen -v -- "$cur") )
+ fi
+
+ return 0
+@}
+@end example
+
+We install the completion function using the @option{-F} option to
+@code{complete}:
+
+@example
+# Tell readline to quote appropriate and append slashes to directories;
+# use the bash default completion for other arguments
+complete -o filenames -o nospace -o bashdefault -F _comp_cd cd
+@end example
+
+@noindent
+Since we'd like Bash and Readline to take care of some
+of the other details for us, we use several other options to tell Bash
+and Readline what to do. The @option{-o filenames} option tells Readline
+that the possible completions should be treated as filenames, and quoted
+appropriately. That option will also cause Readline to append a slash to
+filenames it can determine are directories (which is why we might want to
+extend @code{_comp_cd} to append a slash if we're using directories found
+via @var{CDPATH}: Readline can't tell those completions are directories).
+The @option{-o nospace} option tells Readline to not append a space
+character to the directory name, in case we want to append to it.
+The @option{-o bashdefault} option brings in the rest of the "Bash default"
+completions -- possible completion that Bash adds to the default Readline
+set. These include things like command name completion, variable completion
+for words beginning with @samp{$} or @samp{$@{}, completions containing pathname
+expansion patterns (@pxref{Filename Expansion}), and so on.
+
+Once installed using @code{complete}, @code{_comp_cd} will be called every
+time we attempt word completion for a @code{cd} command.
+
+Many more examples -- an extensive collection of completions for most of
+the common GNU, Unix, and Linux commands -- are available as part of the
+bash_completion project. This is installed by default on many GNU/Linux
+distributions. Originally written by Ian Macdonald, the project now lives
+at @url{https://github.com/scop/bash-completion/}. There are ports for
+other systems such as Solaris and Mac OS X.
+
+An older version of the bash_completion package is distributed with bash
+in the @file{examples/complete} subdirectory.

+<H2> 1.1 Introduction to Line Editing </H2>
+
+
+
+The following paragraphs describe the notation used to represent
+keystrokes.
+
+
+The text <KBD>C-k</KBD> is read as `Control-K' and describes the character
+produced when the <KBD>k</KBD> key is pressed while the Control key
+is depressed.
+
+
+The text <KBD>M-k</KBD> is read as `Meta-K' and describes the character
+produced when the Meta key (if you have one) is depressed, and the <KBD>k</KBD>
+key is pressed.
+The Meta key is labeled <KBD>ALT</KBD> on many keyboards.
+On keyboards with two keys labeled <KBD>ALT</KBD> (usually to either side of
+the space bar), the <KBD>ALT</KBD> on the left side is generally set to
+work as a Meta key.
+The <KBD>ALT</KBD> key on the right may also be configured to work as a
+Meta key or may be configured as some other modifier, such as a
+Compose key for typing accented characters.
+
+
+If you do not have a Meta or <KBD>ALT</KBD> key, or another key working as
+a Meta key, the identical keystroke can be generated by typing <KBD>ESC</KBD>
+first, and then typing <KBD>k</KBD>.
+Either process is known as metafying the <KBD>k</KBD> key.
+
+
+The text <KBD>M-C-k</KBD> is read as `Meta-Control-k' and describes the
+character produced by metafying <KBD>C-k</KBD>.
+
+
+In addition, several keys have their own names. Specifically,
+<KBD>DEL</KBD>, <KBD>ESC</KBD>, <KBD>LFD</KBD>, <KBD>SPC</KBD>, <KBD>RET</KBD>, and <KBD>TAB</KBD> all
+stand for themselves when seen in this text, or in an init file
+(see section <A HREF="rluserman.html#SEC9">1.3 Readline Init File</A>).
+If your keyboard lacks a <KBD>LFD</KBD> key, typing <KBD>C-j</KBD> will
+produce the desired character.
+The <KBD>RET</KBD> key may be labeled <KBD>Return</KBD> or <KBD>Enter</KBD> on
+some keyboards.

+<H2> 1.2 Readline Interaction </H2>
+
+
+
+Often during an interactive session you type in a long line of text,
+only to notice that the first word on the line is misspelled. The
+Readline library gives you a set of commands for manipulating the text
+as you type it in, allowing you to just fix your typo, and not forcing
+you to retype the majority of the line. Using these editing commands,
+you move the cursor to the place that needs correction, and delete or
+insert the text of the corrections. Then, when you are satisfied with
+the line, you simply press <KBD>RET</KBD>. You do not have to be at the
+end of the line to press <KBD>RET</KBD>; the entire line is accepted
+regardless of the location of the cursor within the line.

+
+
+
+In order to enter characters into the line, simply type them. The typed
+character appears where the cursor was, and then the cursor moves one
+space to the right. If you mistype a character, you can use your
+erase character to back up and delete the mistyped character.
+
+
+Sometimes you may mistype a character, and
+not notice the error until you have typed several other characters. In
+that case, you can type <KBD>C-b</KBD> to move the cursor to the left, and then
+correct your mistake. Afterwards, you can move the cursor to the right
+with <KBD>C-f</KBD>.
+
+
+When you add text in the middle of a line, you will notice that characters
+to the right of the cursor are `pushed over' to make room for the text
+that you have inserted. Likewise, when you delete text behind the cursor,
+characters to the right of the cursor are `pulled back' to fill in the
+blank space created by the removal of the text. A list of the bare
+essentials for editing the text of an input line follows.
+
+
+<DL COMPACT>

+empty line.
+</DL>
+
+
+(Depending on your configuration, the <KBD>Backspace</KBD> key be set to
+delete the character to the left of the cursor and the <KBD>DEL</KBD> key set
+to delete the character underneath the cursor, like <KBD>C-d</KBD>, rather
+than the character to the left of the cursor.)

+<H3> 1.2.2 Readline Movement Commands </H3>
+
+
+
+The above table describes the most basic keystrokes that you need
+in order to do editing of the input line. For your convenience, many
+other commands have been added in addition to <KBD>C-b</KBD>, <KBD>C-f</KBD>,
+<KBD>C-d</KBD>, and <KBD>DEL</KBD>. Here are some commands for moving more rapidly
+about the line.
+
+
+<DL COMPACT>
+<DT><KBD>C-a</KBD>
+<DD>Move to the start of the line.
+<DT><KBD>C-e</KBD>
+<DD>Move to the end of the line.
+<DT><KBD>M-f</KBD>
+<DD>Move forward a word, where a word is composed of letters and digits.
+<DT><KBD>M-b</KBD>
+<DD>Move backward a word.
+<DT><KBD>C-l</KBD>
+<DD>Clear the screen, reprinting the current line at the top.
+</DL>
+
+
+Notice how <KBD>C-f</KBD> moves forward a character, while <KBD>M-f</KBD> moves
+forward a word. It is a loose convention that control keystrokes
+operate on characters while meta keystrokes operate on words.

+<A NAME="IDX2"></A>
+
+
+Killing text means to delete the text from the line, but to save
+it away for later use, usually by yanking (re-inserting)
+it back into the line.
+(`Cut' and `paste' are more recent jargon for `kill' and `yank'.)
+
+
+If the description for a command says that it `kills' text, then you can
+be sure that you can get the text back in a different (or the same)
+place later.
+
+
+When you use a kill command, the text is saved in a kill-ring.
+Any number of consecutive kills save all of the killed text together, so
+that when you yank it back, you get it all. The kill
+ring is not line specific; the text that you killed on a previously
+typed line is available to be yanked back later, when you are typing
+another line.
+<A NAME="IDX3"></A>
+
+
+Here is the list of commands for killing text.
+
+
+<DL COMPACT>
+<DT><KBD>C-k</KBD>
+<DD>Kill the text from the current cursor position to the end of the line.
+
+
+<DT><KBD>M-d</KBD>
+<DD>Kill from the cursor to the end of the current word, or, if between
+words, to the end of the next word.
+Word boundaries are the same as those used by <KBD>M-f</KBD>.
+
+
+<DT><KBD>M-<KBD>DEL</KBD></KBD>
+<DD>Kill from the cursor the start of the current word, or, if between
+words, to the start of the previous word.
+Word boundaries are the same as those used by <KBD>M-b</KBD>.
+
+
+<DT><KBD>C-w</KBD>
+<DD>Kill from the cursor to the previous whitespace. This is different than
+<KBD>M-<KBD>DEL</KBD></KBD> because the word boundaries differ.
+
+
+</DL>
+
+
+Here is how to yank the text back into the line. Yanking
+means to copy the most-recently-killed text from the kill buffer.
+
+
+<DL COMPACT>
+<DT><KBD>C-y</KBD>
+<DD>Yank the most recently killed text back into the buffer at the cursor.
+
+
+<DT><KBD>M-y</KBD>
+<DD>Rotate the kill-ring, and yank the new top. You can only do this if
+the prior command is <KBD>C-y</KBD> or <KBD>M-y</KBD>.

+<H3> 1.2.4 Readline Arguments </H3>
+
+
+
+You can pass numeric arguments to Readline commands. Sometimes the
+argument acts as a repeat count, other times it is the sign of the
+argument that is significant. If you pass a negative argument to a
+command which normally acts in a forward direction, that command will
+act in a backward direction. For example, to kill text back to the
+start of the line, you might type <SAMP>`M-- C-k'</SAMP>.
+
+
+The general way to pass numeric arguments to a command is to type meta
+digits before the command. If the first `digit' typed is a minus
+sign (<SAMP>`-'</SAMP>), then the sign of the argument will be negative. Once
+you have typed one meta digit to get the argument started, you can type
+the remainder of the digits, and then the command. For example, to give
+the <KBD>C-d</KBD> command an argument of 10, you could type <SAMP>`M-1 0 C-d'</SAMP>,
+which will delete the next ten characters on the input line.

+<H3> 1.2.5 Searching for Commands in the History </H3>
+
+
+
+Readline provides commands for searching through the command history
+for lines containing a specified string.
+There are two search modes: incremental and non-incremental.
+
+
+Incremental searches begin before the user has finished typing the
+search string.
+As each character of the search string is typed, Readline displays
+the next entry from the history matching the string typed so far.
+An incremental search requires only as many characters as needed to
+find the desired history entry.
+To search backward in the history for a particular string, type
+<KBD>C-r</KBD>. Typing <KBD>C-s</KBD> searches forward through the history.
+The characters present in the value of the <CODE>isearch-terminators</CODE> variable
+are used to terminate an incremental search.
+If that variable has not been assigned a value, the <KBD>ESC</KBD> and
+<KBD>C-J</KBD> characters will terminate an incremental search.
+<KBD>C-g</KBD> will abort an incremental search and restore the original line.
+When the search is terminated, the history entry containing the
+search string becomes the current line.
+
+
+To find other matching entries in the history list, type <KBD>C-r</KBD> or
+<KBD>C-s</KBD> as appropriate.
+This will search backward or forward in the history for the next
+entry matching the search string typed so far.
+Any other key sequence bound to a Readline command will terminate
+the search and execute that command.
+For instance, a <KBD>RET</KBD> will terminate the search and accept
+the line, thereby executing the command from the history list.
+A movement command will terminate the search, make the last line found
+the current line, and begin editing.
+
+
+Readline remembers the last incremental search string. If two
+<KBD>C-r</KBD>s are typed without any intervening characters defining a new
+search string, any remembered search string is used.
+
+
+Non-incremental searches read the entire search string before starting
+to search for matching history lines. The search string may be
+typed by the user or be part of the contents of the current line.

+<H2> 1.3 Readline Init File </H2>
+
+
+
+Although the Readline library comes with a set of Emacs-like
+keybindings installed by default, it is possible to use a different set
+of keybindings.
+Any user can customize programs that use Readline by putting
+commands in an inputrc file, conventionally in his home directory.
+The name of this
+file is taken from the value of the environment variable <CODE>INPUTRC</CODE>. If
+that variable is unset, the default is <TT>`~/.inputrc'</TT>. If that
+file does not exist or cannot be read, the ultimate default is
+<TT>`/etc/inputrc'</TT>.
+
+
+When a program which uses the Readline library starts up, the
+init file is read, and the key bindings are set.
+
+
+In addition, the <CODE>C-x C-r</CODE> command re-reads this init file, thus
+incorporating any changes that you might have made to it.

+<H3> 1.3.1 Readline Init File Syntax </H3>
+
+
+
+There are only a few basic constructs allowed in the
+Readline init file. Blank lines are ignored.
+Lines beginning with a <SAMP>`#'</SAMP> are comments.
+Lines beginning with a <SAMP>`$'</SAMP> indicate conditional
+constructs (see section <A HREF="rluserman.html#SEC11">1.3.2 Conditional Init Constructs</A>). Other lines
+denote variable settings and key bindings.
+
+
+<DL COMPACT>
+<DT>Variable Settings
+<DD>You can modify the run-time behavior of Readline by
+altering the values of variables in Readline
+using the <CODE>set</CODE> command within the init file.
+The syntax is simple:
+
+
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>set <VAR>variable</VAR> <VAR>value</VAR>
+</pre></td></tr></table>
+
+Here, for example, is how to
+change from the default Emacs-like key binding to use
+<CODE>vi</CODE> line editing commands:
+
+
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>set editing-mode vi
+</pre></td></tr></table>
+
+Variable names and values, where appropriate, are recognized without regard
+to case. Unrecognized variable names are ignored.
+
+
+Boolean variables (those that can be set to on or off) are set to on if
+the value is null or empty, <VAR>on</VAR> (case-insensitive), or 1. Any other
+value results in the variable being set to off.
+
+
+A great deal of run-time behavior is changeable with the following
+variables.
+
+
+<A NAME="IDX4"></A>
+<DL COMPACT>
+
+<DT><CODE>bell-style</CODE>
+<DD><A NAME="IDX5"></A>
+Controls what happens when Readline wants to ring the terminal bell.
+If set to <SAMP>`none'</SAMP>, Readline never rings the bell. If set to
+<SAMP>`visible'</SAMP>, Readline uses a visible bell if one is available.
+If set to <SAMP>`audible'</SAMP> (the default), Readline attempts to ring
+the terminal's bell.
+
+
+<DT><CODE>bind-tty-special-chars</CODE>
+<DD><A NAME="IDX6"></A>
+If set to <SAMP>`on'</SAMP> (the default), Readline attempts to bind the control
+characters treated specially by the kernel's terminal driver to their
+Readline equivalents.
+
+
+<DT><CODE>blink-matching-paren</CODE>
+<DD><A NAME="IDX7"></A>
+If set to <SAMP>`on'</SAMP>, Readline attempts to briefly move the cursor to an
+opening parenthesis when a closing parenthesis is inserted. The default
+is <SAMP>`off'</SAMP>.
+
+
+<DT><CODE>colored-completion-prefix</CODE>
+<DD><A NAME="IDX8"></A>
+If set to <SAMP>`on'</SAMP>, when listing completions, Readline displays the
+common prefix of the set of possible completions using a different color.
+The color definitions are taken from the value of the <CODE>LS_COLORS</CODE>
+environment variable.
+The default is <SAMP>`off'</SAMP>.
+
+
+<DT><CODE>colored-stats</CODE>
+<DD><A NAME="IDX9"></A>
+If set to <SAMP>`on'</SAMP>, Readline displays possible completions using different
+colors to indicate their file type.
+The color definitions are taken from the value of the <CODE>LS_COLORS</CODE>
+environment variable.
+The default is <SAMP>`off'</SAMP>.
+
+
+<DT><CODE>comment-begin</CODE>
+<DD><A NAME="IDX10"></A>
+The string to insert at the beginning of the line when the
+<CODE>insert-comment</CODE> command is executed. The default value
+is <CODE>"#"</CODE>.
+
+
+<DT><CODE>completion-display-width</CODE>
+<DD><A NAME="IDX11"></A>
+The number of screen columns used to display possible matches
+when performing completion.
+The value is ignored if it is less than 0 or greater than the terminal
+screen width.
+A value of 0 will cause matches to be displayed one per line.
+The default value is -1.
+
+
+<DT><CODE>completion-ignore-case</CODE>
+<DD><A NAME="IDX12"></A>
+If set to <SAMP>`on'</SAMP>, Readline performs filename matching and completion
+in a case-insensitive fashion.
+The default value is <SAMP>`off'</SAMP>.
+
+
+<DT><CODE>completion-map-case</CODE>
+<DD><A NAME="IDX13"></A>
+If set to <SAMP>`on'</SAMP>, and <VAR>completion-ignore-case</VAR> is enabled, Readline
+treats hyphens (<SAMP>`-'</SAMP>) and underscores (<SAMP>`_'</SAMP>) as equivalent when
+performing case-insensitive filename matching and completion.
+The default value is <SAMP>`off'</SAMP>.
+
+
+<DT><CODE>completion-prefix-display-length</CODE>
+<DD><A NAME="IDX14"></A>
+The length in characters of the common prefix of a list of possible
+completions that is displayed without modification. When set to a
+value greater than zero, common prefixes longer than this value are
+replaced with an ellipsis when displaying possible completions.
+
+
+<DT><CODE>completion-query-items</CODE>
+<DD><A NAME="IDX15"></A>
+The number of possible completions that determines when the user is
+asked whether the list of possibilities should be displayed.
+If the number of possible completions is greater than or equal to this value,
+Readline will ask whether or not the user wishes to view them;
+otherwise, they are simply listed.
+This variable must be set to an integer value greater than or equal to 0.
+A negative value means Readline should never ask.
+The default limit is <CODE>100</CODE>.
+
+
+<DT><CODE>convert-meta</CODE>
+<DD><A NAME="IDX16"></A>
+If set to <SAMP>`on'</SAMP>, Readline will convert characters with the
+eighth bit set to an ASCII key sequence by stripping the eighth
+bit and prefixing an <KBD>ESC</KBD> character, converting them to a
+meta-prefixed key sequence. The default value is <SAMP>`on'</SAMP>, but
+will be set to <SAMP>`off'</SAMP> if the locale is one that contains
+eight-bit characters.
+
+
+<DT><CODE>disable-completion</CODE>
+<DD><A NAME="IDX17"></A>
+If set to <SAMP>`On'</SAMP>, Readline will inhibit word completion.
+Completion characters will be inserted into the line as if they had
+been mapped to <CODE>self-insert</CODE>. The default is <SAMP>`off'</SAMP>.
+
+
+<DT><CODE>echo-control-characters</CODE>
+<DD><A NAME="IDX18"></A>
+When set to <SAMP>`on'</SAMP>, on operating systems that indicate they support it,
+readline echoes a character corresponding to a signal generated from the
+keyboard. The default is <SAMP>`on'</SAMP>.
+
+
+<DT><CODE>editing-mode</CODE>
+<DD><A NAME="IDX19"></A>
+The <CODE>editing-mode</CODE> variable controls which default set of
+key bindings is used. By default, Readline starts up in Emacs editing
+mode, where the keystrokes are most similar to Emacs. This variable can be
+set to either <SAMP>`emacs'</SAMP> or <SAMP>`vi'</SAMP>.
+
+
+<DT><CODE>emacs-mode-string</CODE>
+<DD><A NAME="IDX20"></A>
+If the <VAR>show-mode-in-prompt</VAR> variable is enabled,
+this string is displayed immediately before the last line of the primary
+prompt when emacs editing mode is active. The value is expanded like a
+key binding, so the standard set of meta- and control prefixes and
+backslash escape sequences is available.
+Use the <SAMP>`\1'</SAMP> and <SAMP>`\2'</SAMP> escapes to begin and end sequences of
+non-printing characters, which can be used to embed a terminal control
+sequence into the mode string.
+The default is <SAMP>`@'</SAMP>.
+
+
+<DT><CODE>enable-bracketed-paste</CODE>
+<DD><A NAME="IDX21"></A>
+When set to <SAMP>`On'</SAMP>, Readline will configure the terminal in a way
+that will enable it to insert each paste into the editing buffer as a
+single string of characters, instead of treating each character as if
+it had been read from the keyboard. This can prevent pasted characters
+from being interpreted as editing commands. The default is <SAMP>`On'</SAMP>.
+
+
+<DT><CODE>enable-keypad</CODE>
+<DD><A NAME="IDX22"></A>
+When set to <SAMP>`on'</SAMP>, Readline will try to enable the application
+keypad when it is called. Some systems need this to enable the
+arrow keys. The default is <SAMP>`off'</SAMP>.
+
+
+<DT><CODE>enable-meta-key</CODE>
+<DD>When set to <SAMP>`on'</SAMP>, Readline will try to enable any meta modifier
+key the terminal claims to support when it is called. On many terminals,
+the meta key is used to send eight-bit characters.
+The default is <SAMP>`on'</SAMP>.
+
+
+<DT><CODE>expand-tilde</CODE>
+<DD><A NAME="IDX23"></A>
+If set to <SAMP>`on'</SAMP>, tilde expansion is performed when Readline
+attempts word completion. The default is <SAMP>`off'</SAMP>.
+
+
+<DT><CODE>history-preserve-point</CODE>
+<DD><A NAME="IDX24"></A>
+If set to <SAMP>`on'</SAMP>, the history code attempts to place the point (the
+current cursor position) at the
+same location on each history line retrieved with <CODE>previous-history</CODE>
+or <CODE>next-history</CODE>. The default is <SAMP>`off'</SAMP>.
+
+
+<DT><CODE>history-size</CODE>
+<DD><A NAME="IDX25"></A>
+Set the maximum number of history entries saved in the history list.
+If set to zero, any existing history entries are deleted and no new entries
+are saved.
+If set to a value less than zero, the number of history entries is not
+limited.
+By default, the number of history entries is not limited.
+If an attempt is made to set <VAR>history-size</VAR> to a non-numeric value,
+the maximum number of history entries will be set to 500.
+
+
+<DT><CODE>horizontal-scroll-mode</CODE>
+<DD><A NAME="IDX26"></A>
+This variable can be set to either <SAMP>`on'</SAMP> or <SAMP>`off'</SAMP>. Setting it
+to <SAMP>`on'</SAMP> means that the text of the lines being edited will scroll
+horizontally on a single screen line when they are longer than the width
+of the screen, instead of wrapping onto a new screen line.
+This variable is automatically set to <SAMP>`on'</SAMP> for terminals of height 1.
+By default, this variable is set to <SAMP>`off'</SAMP>.
+
+
+<DT><CODE>input-meta</CODE>
+<DD><A NAME="IDX27"></A>
+<A NAME="IDX28"></A>
+If set to <SAMP>`on'</SAMP>, Readline will enable eight-bit input (it
+will not clear the eighth bit in the characters it reads),
+regardless of what the terminal claims it can support. The
+default value is <SAMP>`off'</SAMP>, but Readline will set it to <SAMP>`on'</SAMP> if the 
+locale contains eight-bit characters.
+The name <CODE>meta-flag</CODE> is a synonym for this variable.
+
+
+<DT><CODE>isearch-terminators</CODE>
+<DD><A NAME="IDX29"></A>
+The string of characters that should terminate an incremental search without
+subsequently executing the character as a command (see section <A HREF="rluserman.html#SEC8">1.2.5 Searching for Commands in the History</A>).
+If this variable has not been given a value, the characters <KBD>ESC</KBD> and
+<KBD>C-J</KBD> will terminate an incremental search.
+
+
+<DT><CODE>keymap</CODE>
+<DD><A NAME="IDX30"></A>
+Sets Readline's idea of the current keymap for key binding commands.
+Built-in <CODE>keymap</CODE> names are
+<CODE>emacs</CODE>,
+<CODE>emacs-standard</CODE>,
+<CODE>emacs-meta</CODE>,
+<CODE>emacs-ctlx</CODE>,
+<CODE>vi</CODE>,
+<CODE>vi-move</CODE>,
+<CODE>vi-command</CODE>, and
+<CODE>vi-insert</CODE>.
+<CODE>vi</CODE> is equivalent to <CODE>vi-command</CODE> (<CODE>vi-move</CODE> is also a
+synonym); <CODE>emacs</CODE> is equivalent to <CODE>emacs-standard</CODE>.
+Applications may add additional names.
+The default value is <CODE>emacs</CODE>.
+The value of the <CODE>editing-mode</CODE> variable also affects the
+default keymap.
+
+
+<DT><CODE>keyseq-timeout</CODE>
+<DD>Specifies the duration Readline will wait for a character when reading an
+ambiguous key sequence (one that can form a complete key sequence using
+the input read so far, or can take additional input to complete a longer
+key sequence).
+If no input is received within the timeout, Readline will use the shorter
+but complete key sequence.
+Readline uses this value to determine whether or not input is
+available on the current input source (<CODE>rl_instream</CODE> by default).
+The value is specified in milliseconds, so a value of 1000 means that
+Readline will wait one second for additional input.
+If this variable is set to a value less than or equal to zero, or to a
+non-numeric value, Readline will wait until another key is pressed to
+decide which key sequence to complete.
+The default value is <CODE>500</CODE>.
+
+
+<DT><CODE>mark-directories</CODE>
+<DD>If set to <SAMP>`on'</SAMP>, completed directory names have a slash
+appended. The default is <SAMP>`on'</SAMP>.
+
+
+<DT><CODE>mark-modified-lines</CODE>
+<DD><A NAME="IDX31"></A>
+This variable, when set to <SAMP>`on'</SAMP>, causes Readline to display an
+asterisk (<SAMP>`*'</SAMP>) at the start of history lines which have been modified.
+This variable is <SAMP>`off'</SAMP> by default.
+
+
+<DT><CODE>mark-symlinked-directories</CODE>
+<DD><A NAME="IDX32"></A>
+If set to <SAMP>`on'</SAMP>, completed names which are symbolic links
+to directories have a slash appended (subject to the value of
+<CODE>mark-directories</CODE>).
+The default is <SAMP>`off'</SAMP>.
+
+
+<DT><CODE>match-hidden-files</CODE>
+<DD><A NAME="IDX33"></A>
+This variable, when set to <SAMP>`on'</SAMP>, causes Readline to match files whose
+names begin with a <SAMP>`.'</SAMP> (hidden files) when performing filename
+completion.
+If set to <SAMP>`off'</SAMP>, the leading <SAMP>`.'</SAMP> must be
+supplied by the user in the filename to be completed.
+This variable is <SAMP>`on'</SAMP> by default.
+
+
+<DT><CODE>menu-complete-display-prefix</CODE>
+<DD><A NAME="IDX34"></A>
+If set to <SAMP>`on'</SAMP>, menu completion displays the common prefix of the
+list of possible completions (which may be empty) before cycling through
+the list. The default is <SAMP>`off'</SAMP>.
+
+
+<DT><CODE>output-meta</CODE>
+<DD><A NAME="IDX35"></A>
+If set to <SAMP>`on'</SAMP>, Readline will display characters with the
+eighth bit set directly rather than as a meta-prefixed escape
+sequence.
+The default is <SAMP>`off'</SAMP>, but Readline will set it to <SAMP>`on'</SAMP> if the
+locale contains eight-bit characters.
+
+
+<DT><CODE>page-completions</CODE>
+<DD><A NAME="IDX36"></A>
+If set to <SAMP>`on'</SAMP>, Readline uses an internal <CODE>more</CODE>-like pager
+to display a screenful of possible completions at a time.
+This variable is <SAMP>`on'</SAMP> by default.
+
+
+<DT><CODE>print-completions-horizontally</CODE>
+<DD>If set to <SAMP>`on'</SAMP>, Readline will display completions with matches
+sorted horizontally in alphabetical order, rather than down the screen.
+The default is <SAMP>`off'</SAMP>.
+
+
+<DT><CODE>revert-all-at-newline</CODE>
+<DD><A NAME="IDX37"></A>
+If set to <SAMP>`on'</SAMP>, Readline will undo all changes to history lines
+before returning when <CODE>accept-line</CODE> is executed. By default,
+history lines may be modified and retain individual undo lists across
+calls to <CODE>readline</CODE>. The default is <SAMP>`off'</SAMP>.
+
+
+<DT><CODE>show-all-if-ambiguous</CODE>
+<DD><A NAME="IDX38"></A>
+This alters the default behavior of the completion functions. If
+set to <SAMP>`on'</SAMP>, 
+words which have more than one possible completion cause the
+matches to be listed immediately instead of ringing the bell.
+The default value is <SAMP>`off'</SAMP>.
+
+
+<DT><CODE>show-all-if-unmodified</CODE>
+<DD><A NAME="IDX39"></A>
+This alters the default behavior of the completion functions in
+a fashion similar to <VAR>show-all-if-ambiguous</VAR>.
+If set to <SAMP>`on'</SAMP>, 
+words which have more than one possible completion without any
+possible partial completion (the possible completions don't share
+a common prefix) cause the matches to be listed immediately instead
+of ringing the bell.
+The default value is <SAMP>`off'</SAMP>.
+
+
+<DT><CODE>show-mode-in-prompt</CODE>
+<DD><A NAME="IDX40"></A>
+If set to <SAMP>`on'</SAMP>, add a string to the beginning of the prompt
+indicating the editing mode: emacs, vi command, or vi insertion.
+The mode strings are user-settable (e.g., <VAR>emacs-mode-string</VAR>).
+The default value is <SAMP>`off'</SAMP>.
+
+
+<DT><CODE>skip-completed-text</CODE>
+<DD><A NAME="IDX41"></A>
+If set to <SAMP>`on'</SAMP>, this alters the default completion behavior when
+inserting a single match into the line. It's only active when
+performing completion in the middle of a word. If enabled, readline
+does not insert characters from the completion that match characters
+after point in the word being completed, so portions of the word
+following the cursor are not duplicated.
+For instance, if this is enabled, attempting completion when the cursor
+is after the <SAMP>`e'</SAMP> in <SAMP>`Makefile'</SAMP> will result in <SAMP>`Makefile'</SAMP>
+rather than <SAMP>`Makefilefile'</SAMP>, assuming there is a single possible
+completion.
+The default value is <SAMP>`off'</SAMP>.
+
+
+<DT><CODE>vi-cmd-mode-string</CODE>
+<DD><A NAME="IDX42"></A>
+If the <VAR>show-mode-in-prompt</VAR> variable is enabled,
+this string is displayed immediately before the last line of the primary
+prompt when vi editing mode is active and in command mode.
+The value is expanded like a
+key binding, so the standard set of meta- and control prefixes and
+backslash escape sequences is available.
+Use the <SAMP>`\1'</SAMP> and <SAMP>`\2'</SAMP> escapes to begin and end sequences of
+non-printing characters, which can be used to embed a terminal control
+sequence into the mode string.
+The default is <SAMP>`(cmd)'</SAMP>.
+
+
+<DT><CODE>vi-ins-mode-string</CODE>
+<DD><A NAME="IDX43"></A>
+If the <VAR>show-mode-in-prompt</VAR> variable is enabled,
+this string is displayed immediately before the last line of the primary
+prompt when vi editing mode is active and in insertion mode.
+The value is expanded like a
+key binding, so the standard set of meta- and control prefixes and
+backslash escape sequences is available.
+Use the <SAMP>`\1'</SAMP> and <SAMP>`\2'</SAMP> escapes to begin and end sequences of
+non-printing characters, which can be used to embed a terminal control
+sequence into the mode string.
+The default is <SAMP>`(ins)'</SAMP>.
+
+
+<DT><CODE>visible-stats</CODE>
+<DD><A NAME="IDX44"></A>
+If set to <SAMP>`on'</SAMP>, a character denoting a file's type
+is appended to the filename when listing possible
+completions. The default is <SAMP>`off'</SAMP>.
+
+
+</DL>
+
+
+<DT>Key Bindings
+<DD>The syntax for controlling key bindings in the init file is
+simple. First you need to find the name of the command that you
+want to change. The following sections contain tables of the command
+name, the default keybinding, if any, and a short description of what
+the command does.
+
+
+Once you know the name of the command, simply place on a line
+in the init file the name of the key
+you wish to bind the command to, a colon, and then the name of the
+command.
+There can be no space between the key name and the colon -- that will be
+interpreted as part of the key name.
+The name of the key can be expressed in different ways, depending on
+what you find most comfortable.
+
+
+In addition to command names, readline allows keys to be bound
+to a string that is inserted when the key is pressed (a <VAR>macro</VAR>).
+
+
+<DL COMPACT>
+<DT><VAR>keyname</VAR>: <VAR>function-name</VAR> or <VAR>macro</VAR>
+<DD><VAR>keyname</VAR> is the name of a key spelled out in English. For example:
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>Control-u: universal-argument
+Meta-Rubout: backward-kill-word
+Control-o: "&#62; output"
+</pre></td></tr></table>
+
+In the example above, <KBD>C-u</KBD> is bound to the function
+<CODE>universal-argument</CODE>,
+<KBD>M-DEL</KBD> is bound to the function <CODE>backward-kill-word</CODE>, and
+<KBD>C-o</KBD> is bound to run the macro
+expressed on the right hand side (that is, to insert the text
+<SAMP>`&#62; output'</SAMP> into the line).
+
+
+A number of symbolic character names are recognized while
+processing this key binding syntax:
+<VAR>DEL</VAR>,
+<VAR>ESC</VAR>,
+<VAR>ESCAPE</VAR>,
+<VAR>LFD</VAR>,
+<VAR>NEWLINE</VAR>,
+<VAR>RET</VAR>,
+<VAR>RETURN</VAR>,
+<VAR>RUBOUT</VAR>,
+<VAR>SPACE</VAR>,
+<VAR>SPC</VAR>,
+and
+<VAR>TAB</VAR>.
+
+
+<DT>"<VAR>keyseq</VAR>": <VAR>function-name</VAR> or <VAR>macro</VAR>
+<DD><VAR>keyseq</VAR> differs from <VAR>keyname</VAR> above in that strings
+denoting an entire key sequence can be specified, by placing
+the key sequence in double quotes. Some GNU Emacs style key
+escapes can be used, as in the following example, but the
+special character names are not recognized.
+
+
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>"\C-u": universal-argument
+"\C-x\C-r": re-read-init-file
+"\e11~": "Function Key 1"
+</pre></td></tr></table>
+
+In the above example, <KBD>C-u</KBD> is again bound to the function
+<CODE>universal-argument</CODE> (just as it was in the first example),
+<SAMP>`<KBD>C-x</KBD> <KBD>C-r</KBD>'</SAMP> is bound to the function <CODE>re-read-init-file</CODE>,
+and <SAMP>`<KBD>ESC</KBD> <KBD></KBD> <KBD>1</KBD> <KBD>1</KBD> <KBD>~</KBD>'</SAMP> is bound to insert
+the text <SAMP>`Function Key 1'</SAMP>.
+
+
+</DL>
+
+
+The following GNU Emacs style escape sequences are available when
+specifying key sequences:
+
+
+<DL COMPACT>
+<DT><CODE><KBD>\C-</KBD></CODE>
+<DD>control prefix
+<DT><CODE><KBD>\M-</KBD></CODE>
+<DD>meta prefix
+<DT><CODE><KBD>\e</KBD></CODE>
+<DD>an escape character
+<DT><CODE><KBD>\\</KBD></CODE>
+<DD>backslash
+<DT><CODE><KBD>\"</KBD></CODE>
+<DD><KBD>"</KBD>, a double quotation mark
+<DT><CODE><KBD>\'</KBD></CODE>
+<DD><KBD>'</KBD>, a single quote or apostrophe
+</DL>
+
+
+In addition to the GNU Emacs style escape sequences, a second
+set of backslash escapes is available:
+
+
+<DL COMPACT>
+<DT><CODE>\a</CODE>
+<DD>alert (bell)
+<DT><CODE>\b</CODE>
+<DD>backspace
+<DT><CODE>\d</CODE>
+<DD>delete
+<DT><CODE>\f</CODE>
+<DD>form feed
+<DT><CODE>\n</CODE>
+<DD>newline
+<DT><CODE>\r</CODE>
+<DD>carriage return
+<DT><CODE>\t</CODE>
+<DD>horizontal tab
+<DT><CODE>\v</CODE>
+<DD>vertical tab
+<DT><CODE>\<VAR>nnn</VAR></CODE>
+<DD>the eight-bit character whose value is the octal value <VAR>nnn</VAR>
+(one to three digits)
+<DT><CODE>\x<VAR>HH</VAR></CODE>
+<DD>the eight-bit character whose value is the hexadecimal value <VAR>HH</VAR>
+(one or two hex digits)
+</DL>
+
+
+When entering the text of a macro, single or double quotes must
+be used to indicate a macro definition.
+Unquoted text is assumed to be a function name.
+In the macro body, the backslash escapes described above are expanded.
+Backslash will quote any other character in the macro text,
+including <SAMP>`"'</SAMP> and <SAMP>`''</SAMP>.
+For example, the following binding will make <SAMP>`<KBD>C-x</KBD> \'</SAMP>
+insert a single <SAMP>`\'</SAMP> into the line:
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>"\C-x\\": "\\"

+<H3> 1.3.2 Conditional Init Constructs </H3>
+
+
+
+Readline implements a facility similar in spirit to the conditional
+compilation features of the C preprocessor which allows key
+bindings and variable settings to be performed as the result
+of tests. There are four parser directives used.
+
+
+<DL COMPACT>
+<DT><CODE>$if</CODE>
+<DD>The <CODE>$if</CODE> construct allows bindings to be made based on the
+editing mode, the terminal being used, or the application using
+Readline. The text of the test, after any comparison operator,
+extends to the end of the line;
+unless otherwise noted, no characters are required to isolate it.
+
+
+<DL COMPACT>
+<DT><CODE>mode</CODE>
+<DD>The <CODE>mode=</CODE> form of the <CODE>$if</CODE> directive is used to test
+whether Readline is in <CODE>emacs</CODE> or <CODE>vi</CODE> mode.
+This may be used in conjunction
+with the <SAMP>`set keymap'</SAMP> command, for instance, to set bindings in
+the <CODE>emacs-standard</CODE> and <CODE>emacs-ctlx</CODE> keymaps only if
+Readline is starting out in <CODE>emacs</CODE> mode.
+
+
+<DT><CODE>term</CODE>
+<DD>The <CODE>term=</CODE> form may be used to include terminal-specific
+key bindings, perhaps to bind the key sequences output by the
+terminal's function keys. The word on the right side of the
+<SAMP>`='</SAMP> is tested against both the full name of the terminal and
+the portion of the terminal name before the first <SAMP>`-'</SAMP>. This
+allows <CODE>sun</CODE> to match both <CODE>sun</CODE> and <CODE>sun-cmd</CODE>,
+for instance.
+
+
+<DT><CODE>version</CODE>
+<DD>The <CODE>version</CODE> test may be used to perform comparisons against
+specific Readline versions.
+The <CODE>version</CODE> expands to the current Readline version.
+The set of comparison operators includes
+<SAMP>`='</SAMP> (and <SAMP>`=='</SAMP>), <SAMP>`!='</SAMP>, <SAMP>`&#60;='</SAMP>, <SAMP>`&#62;='</SAMP>, <SAMP>`&#60;'</SAMP>,
+and <SAMP>`&#62;'</SAMP>.
+The version number supplied on the right side of the operator consists
+of a major version number, an optional decimal point, and an optional
+minor version (e.g., <SAMP>`7.1'</SAMP>). If the minor version is omitted, it
+is assumed to be <SAMP>`0'</SAMP>.
+The operator may be separated from the string <CODE>version</CODE> and
+from the version number argument by whitespace.
+The following example sets a variable if the Readline version being used
+is 7.0 or newer:
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>$if version &#62;= 7.0
+set show-mode-in-prompt on
+$endif
+</pre></td></tr></table>
+
+<DT><CODE>application</CODE>
+<DD>The <VAR>application</VAR> construct is used to include
+application-specific settings. Each program using the Readline
+library sets the <VAR>application name</VAR>, and you can test for
+a particular value. 
+This could be used to bind key sequences to functions useful for
+a specific program. For instance, the following command adds a
+key sequence that quotes the current or previous word in Bash:
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>$if Bash
+# Quote the current or previous word
+"\C-xq": "\eb\"\ef\""
+$endif
+</pre></td></tr></table>
+
+<DT><CODE>variable</CODE>
+<DD>The <VAR>variable</VAR> construct provides simple equality tests for Readline
+variables and values.
+The permitted comparison operators are <SAMP>`='</SAMP>, <SAMP>`=='</SAMP>, and <SAMP>`!='</SAMP>.
+The variable name must be separated from the comparison operator by
+whitespace; the operator may be separated from the value on the right hand
+side by whitespace.
+Both string and boolean variables may be tested. Boolean variables must be
+tested against the values <VAR>on</VAR> and <VAR>off</VAR>.
+The following example is equivalent to the <CODE>mode=emacs</CODE> test described
+above:
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>$if editing-mode == emacs
+set show-mode-in-prompt on
+$endif
+</pre></td></tr></table></DL>
+
+
+<DT><CODE>$endif</CODE>
+<DD>This command, as seen in the previous example, terminates an
+<CODE>$if</CODE> command.
+
+
+<DT><CODE>$else</CODE>
+<DD>Commands in this branch of the <CODE>$if</CODE> directive are executed if
+the test fails.
+
+
+<DT><CODE>$include</CODE>
+<DD>This directive takes a single filename as an argument and reads commands
+and bindings from that file.
+For example, the following directive reads from <TT>`/etc/inputrc'</TT>:
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>$include /etc/inputrc
+</pre></td></tr></table></DL>

+<DT><CODE>reverse-search-history (C-r)</CODE>
+<DD><A NAME="IDX78"></A>
+Search backward starting at the current line and moving `up' through
+the history as necessary. This is an incremental search.

+
+<A NAME="IDX81"></A>
+<DT><CODE>non-incremental-reverse-search-history (M-p)</CODE>
+<DD><A NAME="IDX82"></A>
+Search backward starting at the current line and moving `up'

+
+<A NAME="IDX87"></A>
+<DT><CODE>history-search-backward ()</CODE>
+<DD><A NAME="IDX88"></A>
+Search backward through the history for the string of characters
+between the start of the current line and the point.

+<DT><CODE>yank-nth-arg (M-C-y)</CODE>
+<DD><A NAME="IDX94"></A>
+Insert the first argument to the previous command (usually
+the second word on the previous line) at point.
+With an argument <VAR>n</VAR>,
+insert the <VAR>n</VAR>th word from the previous command (the words
+in the previous command begin with word 0). A negative argument
+inserts the <VAR>n</VAR>th word from the end of the previous command.
+Once the argument <VAR>n</VAR> is computed, the argument is extracted
+as if the <SAMP>`!<VAR>n</VAR>'</SAMP> history expansion had been specified.
+

+Insert last argument to the previous command (the last word of the
+previous history entry).
+With a numeric argument, behave exactly like <CODE>yank-nth-arg</CODE>.
+Successive calls to <CODE>yank-last-arg</CODE> move back through the history
+list, inserting the last word (or the word specified by the argument to
+the first call) of each line in turn.
+Any numeric argument supplied to these successive calls determines
+the direction to move through the history. A negative argument switches
+the direction through the history (back or forward).
+The history expansion facilities are used to extract the last argument,
+as if the <SAMP>`!$'</SAMP> history expansion had been specified.
+
+

+newline had been entered,
+and fetch the next line relative to the current line from the history
+for editing.
+A numeric argument, if supplied, specifies the history entry to use instead
+of the current line.

+<H3> 1.4.3 Commands For Changing Text </H3>
+
+
+
+<DL COMPACT>
+
+<A NAME="IDX99"></A>
+<DT><CODE>end-of-file (usually C-d)</CODE>
+<DD><A NAME="IDX100"></A>
+The character indicating end-of-file as set, for example, by
+<CODE>stty</CODE>. If this character is read when there are no characters
+on the line, and point is at the beginning of the line, Readline
+interprets it as the end of input and returns EOF.
+
+
+<A NAME="IDX101"></A>
+<DT><CODE>delete-char (C-d)</CODE>
+<DD><A NAME="IDX102"></A>
+Delete the character at point. If this function is bound to the
+same character as the tty EOF character, as <KBD>C-d</KBD>
+commonly is, see above for the effects.
+
+
+<A NAME="IDX103"></A>
+<DT><CODE>backward-delete-char (Rubout)</CODE>
+<DD><A NAME="IDX104"></A>
+Delete the character behind the cursor. A numeric argument means
+to kill the characters instead of deleting them.
+
+
+<A NAME="IDX105"></A>
+<DT><CODE>forward-backward-delete-char ()</CODE>
+<DD><A NAME="IDX106"></A>
+Delete the character under the cursor, unless the cursor is at the
+end of the line, in which case the character behind the cursor is
+deleted. By default, this is not bound to a key.
+
+
+<A NAME="IDX107"></A>
+<DT><CODE>quoted-insert (C-q or C-v)</CODE>
+<DD><A NAME="IDX108"></A>
+Add the next character typed to the line verbatim. This is
+how to insert key sequences like <KBD>C-q</KBD>, for example.
+
+
+<A NAME="IDX109"></A>
+<DT><CODE>tab-insert (M-<KBD>TAB</KBD>)</CODE>
+<DD><A NAME="IDX110"></A>
+Insert a tab character.
+
+
+<A NAME="IDX111"></A>
+<DT><CODE>self-insert (a, b, A, 1, !, ...)</CODE>
+<DD><A NAME="IDX112"></A>
+Insert yourself.
+
+
+<A NAME="IDX113"></A>
+<DT><CODE>bracketed-paste-begin ()</CODE>
+<DD><A NAME="IDX114"></A>
+This function is intended to be bound to the "bracketed paste" escape
+sequence sent by some terminals, and such a binding is assigned by default.
+It allows Readline to insert the pasted text as a single unit without treating
+each character as if it had been read from the keyboard. The characters
+are inserted as if each one was bound to <CODE>self-insert</CODE> instead of
+executing any editing commands.
+
+
+Bracketed paste sets the region (the characters between point and the mark)
+to the inserted text. It uses the concept of an active mark: when the
+mark is active, Readline redisplay uses the terminal's standout mode to
+denote the region.
+
+
+<A NAME="IDX115"></A>
+<DT><CODE>transpose-chars (C-t)</CODE>
+<DD><A NAME="IDX116"></A>
+Drag the character before the cursor forward over
+the character at the cursor, moving the
+cursor forward as well. If the insertion point
+is at the end of the line, then this
+transposes the last two characters of the line.
+Negative arguments have no effect.
+
+
+<A NAME="IDX117"></A>
+<DT><CODE>transpose-words (M-t)</CODE>
+<DD><A NAME="IDX118"></A>
+Drag the word before point past the word after point,
+moving point past that word as well.
+If the insertion point is at the end of the line, this transposes
+the last two words on the line.
+
+
+<A NAME="IDX119"></A>
+<DT><CODE>upcase-word (M-u)</CODE>
+<DD><A NAME="IDX120"></A>
+Uppercase the current (or following) word. With a negative argument,
+uppercase the previous word, but do not move the cursor.
+
+
+<A NAME="IDX121"></A>
+<DT><CODE>downcase-word (M-l)</CODE>
+<DD><A NAME="IDX122"></A>
+Lowercase the current (or following) word. With a negative argument,
+lowercase the previous word, but do not move the cursor.
+
+
+<A NAME="IDX123"></A>
+<DT><CODE>capitalize-word (M-c)</CODE>
+<DD><A NAME="IDX124"></A>
+Capitalize the current (or following) word. With a negative argument,
+capitalize the previous word, but do not move the cursor.
+
+
+<A NAME="IDX125"></A>
+<DT><CODE>overwrite-mode ()</CODE>
+<DD><A NAME="IDX126"></A>
+Toggle overwrite mode. With an explicit positive numeric argument,
+switches to overwrite mode. With an explicit non-positive numeric
+argument, switches to insert mode. This command affects only
+<CODE>emacs</CODE> mode; <CODE>vi</CODE> mode does overwrite differently.
+Each call to <CODE>readline()</CODE> starts in insert mode.
+
+
+In overwrite mode, characters bound to <CODE>self-insert</CODE> replace
+the text at point rather than pushing the text to the right.
+Characters bound to <CODE>backward-delete-char</CODE> replace the character
+before point with a space.
+
+
+By default, this command is unbound.

+
+
+
+While the Readline library does not have a full set of <CODE>vi</CODE>
+editing functions, it does contain enough to allow simple editing
+of the line. The Readline <CODE>vi</CODE> mode behaves as specified in
+the POSIX standard.
+
+
+In order to switch interactively between <CODE>emacs</CODE> and <CODE>vi</CODE>
+editing modes, use the command <KBD>M-C-j</KBD> (bound to emacs-editing-mode
+when in <CODE>vi</CODE> mode and to vi-editing-mode in <CODE>emacs</CODE> mode).
+The Readline default is <CODE>emacs</CODE> mode.
+
+
+When you enter a line in <CODE>vi</CODE> mode, you are already placed in
+`insertion' mode, as if you had typed an <SAMP>`i'</SAMP>. Pressing <KBD>ESC</KBD>
+switches you into `command' mode, where you can edit the text of the
+line with the standard <CODE>vi</CODE> movement keys, move to previous
+history lines with <SAMP>`k'</SAMP> and subsequent lines with <SAMP>`j'</SAMP>, and
+so forth.

+PREAMBLE
+
+
+The purpose of this License is to make a manual, textbook, or other
+functional and useful document free in the sense of freedom: to
+assure everyone the effective freedom to copy and redistribute it,
+with or without modifying it, either commercially or noncommercially.
+Secondarily, this License preserves for the author and publisher a way
+to get credit for their work, while not being considered responsible
+for modifications made by others.
+
+
+This License is a kind of "copyleft", which means that derivative
+works of the document must themselves be free in the same sense. It
+complements the GNU General Public License, which is a copyleft
+license designed for free software.
+
+
+We have designed this License in order to use it for manuals for free
+software, because free software needs free documentation: a free
+program should come with manuals providing the same freedoms that the
+software does. But this License is not limited to software manuals;
+it can be used for any textual work, regardless of subject matter or
+whether it is published as a printed book. We recommend this License
+principally for works whose purpose is instruction or reference.
+
+
+<LI>
+APPLICABILITY AND DEFINITIONS
+
+
+This License applies to any manual or other work, in any medium, that
+contains a notice placed by the copyright holder saying it can be
+distributed under the terms of this License. Such a notice grants a
+world-wide, royalty-free license, unlimited in duration, to use that
+work under the conditions stated herein. The "Document", below,
+refers to any such manual or work. Any member of the public is a
+licensee, and is addressed as "you". You accept the license if you
+copy, modify or distribute the work in a way requiring permission
+under copyright law.
+
+
+A "Modified Version" of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with
+modifications and/or translated into another language.
+
+
+A "Secondary Section" is a named appendix or a front-matter section
+of the Document that deals exclusively with the relationship of the
+publishers or authors of the Document to the Document's overall
+subject (or to related matters) and contains nothing that could fall
+directly within that overall subject. (Thus, if the Document is in
+part a textbook of mathematics, a Secondary Section may not explain
+any mathematics.) The relationship could be a matter of historical
+connection with the subject or with related matters, or of legal,
+commercial, philosophical, ethical or political position regarding
+them.
+
+
+The "Invariant Sections" are certain Secondary Sections whose titles
+are designated, as being those of Invariant Sections, in the notice
+that says that the Document is released under this License. If a
+section does not fit the above definition of Secondary then it is not
+allowed to be designated as Invariant. The Document may contain zero
+Invariant Sections. If the Document does not identify any Invariant
+Sections then there are none.
+
+
+The "Cover Texts" are certain short passages of text that are listed,
+as Front-Cover Texts or Back-Cover Texts, in the notice that says that
+the Document is released under this License. A Front-Cover Text may
+be at most 5 words, and a Back-Cover Text may be at most 25 words.
+
+
+A "Transparent" copy of the Document means a machine-readable copy,
+represented in a format whose specification is available to the
+general public, that is suitable for revising the document
+straightforwardly with generic text editors or (for images composed of
+pixels) generic paint programs or (for drawings) some widely available
+drawing editor, and that is suitable for input to text formatters or
+for automatic translation to a variety of formats suitable for input
+to text formatters. A copy made in an otherwise Transparent file
+format whose markup, or absence of markup, has been arranged to thwart
+or discourage subsequent modification by readers is not Transparent.
+An image format is not Transparent if used for any substantial amount
+of text. A copy that is not "Transparent" is called "Opaque".
+
+
+Examples of suitable formats for Transparent copies include plain
+ASCII without markup, Texinfo input format, LaTeX input
+format, SGML or XML using a publicly available
+DTD, and standard-conforming simple HTML,
+PostScript or PDF designed for human modification. Examples
+of transparent image formats include PNG, XCF and
+JPG. Opaque formats include proprietary formats that can be
+read and edited only by proprietary word processors, SGML or
+XML for which the DTD and/or processing tools are
+not generally available, and the machine-generated HTML,
+PostScript or PDF produced by some word processors for
+output purposes only.
+
+
+The "Title Page" means, for a printed book, the title page itself,
+plus such following pages as are needed to hold, legibly, the material
+this License requires to appear in the title page. For works in
+formats which do not have any title page as such, "Title Page" means
+the text near the most prominent appearance of the work's title,
+preceding the beginning of the body of the text.
+
+
+The "publisher" means any person or entity that distributes copies
+of the Document to the public.
+
+
+A section "Entitled XYZ" means a named subunit of the Document whose
+title either is precisely XYZ or contains XYZ in parentheses following
+text that translates XYZ in another language. (Here XYZ stands for a
+specific section name mentioned below, such as "Acknowledgements",
+"Dedications", "Endorsements", or "History".) To "Preserve the Title"
+of such a section when you modify the Document means that it remains a
+section "Entitled XYZ" according to this definition.
+
+
+The Document may include Warranty Disclaimers next to the notice which
+states that this License applies to the Document. These Warranty
+Disclaimers are considered to be included by reference in this
+License, but only as regards disclaiming warranties: any other
+implication that these Warranty Disclaimers may have is void and has
+no effect on the meaning of this License.
+
+
+<LI>
+VERBATIM COPYING
+
+
+You may copy and distribute the Document in any medium, either
+commercially or noncommercially, provided that this License, the
+copyright notices, and the license notice saying this License applies
+to the Document are reproduced in all copies, and that you add no other
+conditions whatsoever to those of this License. You may not use
+technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute. However, you may accept
+compensation in exchange for copies. If you distribute a large enough
+number of copies you must also follow the conditions in section 3.
+
+
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+
+
+<LI>
+COPYING IN QUANTITY
+
+
+If you publish printed copies (or copies in media that commonly have
+printed covers) of the Document, numbering more than 100, and the
+Document's license notice requires Cover Texts, you must enclose the
+copies in covers that carry, clearly and legibly, all these Cover
+Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
+the back cover. Both covers must also clearly and legibly identify
+you as the publisher of these copies. The front cover must present
+the full title with all words of the title equally prominent and
+visible. You may add other material on the covers in addition.
+Copying with changes limited to the covers, as long as they preserve
+the title of the Document and satisfy these conditions, can be treated
+as verbatim copying in other respects.
+
+
+If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+
+
+If you publish or distribute Opaque copies of the Document numbering
+more than 100, you must either include a machine-readable Transparent
+copy along with each Opaque copy, or state in or with each Opaque copy
+a computer-network location from which the general network-using
+public has access to download using public-standard network protocols
+a complete Transparent copy of the Document, free of added material.
+If you use the latter option, you must take reasonably prudent steps,
+when you begin distribution of Opaque copies in quantity, to ensure
+that this Transparent copy will remain thus accessible at the stated
+location until at least one year after the last time you distribute an
+Opaque copy (directly or through your agents or retailers) of that
+edition to the public.
+
+
+It is requested, but not required, that you contact the authors of the
+Document well before redistributing any large number of copies, to give
+them a chance to provide you with an updated version of the Document.
+
+
+<LI>
+MODIFICATIONS
+
+
+You may copy and distribute a Modified Version of the Document under
+the conditions of sections 2 and 3 above, provided that you release
+the Modified Version under precisely this License, with the Modified
+Version filling the role of the Document, thus licensing distribution
+and modification of the Modified Version to whoever possesses a copy
+of it. In addition, you must do these things in the Modified Version:
+
+
+<OL>
+<LI>
+Use in the Title Page (and on the covers, if any) a title distinct
+from that of the Document, and from those of previous versions
+(which should, if there were any, be listed in the History section
+of the Document). You may use the same title as a previous version
+if the original publisher of that version gives permission.
+
+
+<LI>
+List on the Title Page, as authors, one or more persons or entities
+responsible for authorship of the modifications in the Modified
+Version, together with at least five of the principal authors of the
+Document (all of its principal authors, if it has fewer than five),
+unless they release you from this requirement.
+
+
+<LI>
+State on the Title page the name of the publisher of the
+Modified Version, as the publisher.
+
+
+<LI>
+Preserve all the copyright notices of the Document.
+
+
+<LI>
+Add an appropriate copyright notice for your modifications
+adjacent to the other copyright notices.
+
+
+<LI>
+Include, immediately after the copyright notices, a license notice
+giving the public permission to use the Modified Version under the
+terms of this License, in the form shown in the Addendum below.
+
+
+<LI>
+Preserve in that license notice the full lists of Invariant Sections
+and required Cover Texts given in the Document's license notice.
+
+
+<LI>
+Include an unaltered copy of this License.
+
+
+<LI>
+Preserve the section Entitled "History", Preserve its Title, and add
+to it an item stating at least the title, year, new authors, and
+publisher of the Modified Version as given on the Title Page. If
+there is no section Entitled "History" in the Document, create one
+stating the title, year, authors, and publisher of the Document as
+given on its Title Page, then add an item describing the Modified
+Version as stated in the previous sentence.
+
+
+<LI>
+Preserve the network location, if any, given in the Document for
+public access to a Transparent copy of the Document, and likewise
+the network locations given in the Document for previous versions
+it was based on. These may be placed in the "History" section.
+You may omit a network location for a work that was published at
+least four years before the Document itself, or if the original
+publisher of the version it refers to gives permission.
+
+
+<LI>
+For any section Entitled "Acknowledgements" or "Dedications", Preserve
+the Title of the section, and preserve in the section all the
+substance and tone of each of the contributor acknowledgements and/or
+dedications given therein.
+
+
+<LI>
+Preserve all the Invariant Sections of the Document,
+unaltered in their text and in their titles. Section numbers
+or the equivalent are not considered part of the section titles.
+
+
+<LI>
+Delete any section Entitled "Endorsements". Such a section
+may not be included in the Modified Version.
+
+
+<LI>
+Do not retitle any existing section to be Entitled "Endorsements" or
+to conflict in title with any Invariant Section.
+
+
+<LI>
+Preserve any Warranty Disclaimers.
+</OL>
+
+
+If the Modified Version includes new front-matter sections or
+appendices that qualify as Secondary Sections and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant. To do this, add their titles to the
+list of Invariant Sections in the Modified Version's license notice.
+These titles must be distinct from any other section titles.
+
+
+You may add a section Entitled "Endorsements", provided it contains
+nothing but endorsements of your Modified Version by various
+parties--for example, statements of peer review or that the text has
+been approved by an organization as the authoritative definition of a
+standard.
+
+
+You may add a passage of up to five words as a Front-Cover Text, and a
+passage of up to 25 words as a Back-Cover Text, to the end of the list
+of Cover Texts in the Modified Version. Only one passage of
+Front-Cover Text and one of Back-Cover Text may be added by (or
+through arrangements made by) any one entity. If the Document already
+includes a cover text for the same cover, previously added by you or
+by arrangement made by the same entity you are acting on behalf of,
+you may not add another; but you may replace the old one, on explicit
+permission from the previous publisher that added the old one.
+
+
+The author(s) and publisher(s) of the Document do not by this License
+give permission to use their names for publicity for or to assert or
+imply endorsement of any Modified Version.
+
+
+<LI>
+COMBINING DOCUMENTS
+
+
+You may combine the Document with other documents released under this
+License, under the terms defined in section 4 above for modified
+versions, provided that you include in the combination all of the
+Invariant Sections of all of the original documents, unmodified, and
+list them all as Invariant Sections of your combined work in its
+license notice, and that you preserve all their Warranty Disclaimers.
+
+
+The combined work need only contain one copy of this License, and
+multiple identical Invariant Sections may be replaced with a single
+copy. If there are multiple Invariant Sections with the same name but
+different contents, make the title of each such section unique by
+adding at the end of it, in parentheses, the name of the original
+author or publisher of that section if known, or else a unique number.
+Make the same adjustment to the section titles in the list of
+Invariant Sections in the license notice of the combined work.
+
+
+In the combination, you must combine any sections Entitled "History"
+in the various original documents, forming one section Entitled
+"History"; likewise combine any sections Entitled "Acknowledgements",
+and any sections Entitled "Dedications". You must delete all
+sections Entitled "Endorsements."
+
+
+<LI>
+COLLECTIONS OF DOCUMENTS
+
+
+You may make a collection consisting of the Document and other documents
+released under this License, and replace the individual copies of this
+License in the various documents with a single copy that is included in
+the collection, provided that you follow the rules of this License for
+verbatim copying of each of the documents in all other respects.
+
+
+You may extract a single document from such a collection, and distribute
+it individually under this License, provided you insert a copy of this
+License into the extracted document, and follow this License in all
+other respects regarding verbatim copying of that document.
+
+
+<LI>
+AGGREGATION WITH INDEPENDENT WORKS
+
+
+A compilation of the Document or its derivatives with other separate
+and independent documents or works, in or on a volume of a storage or
+distribution medium, is called an "aggregate" if the copyright
+resulting from the compilation is not used to limit the legal rights
+of the compilation's users beyond what the individual works permit.
+When the Document is included in an aggregate, this License does not
+apply to the other works in the aggregate which are not themselves
+derivative works of the Document.
+
+
+If the Cover Text requirement of section 3 is applicable to these
+copies of the Document, then if the Document is less than one half of
+the entire aggregate, the Document's Cover Texts may be placed on
+covers that bracket the Document within the aggregate, or the
+electronic equivalent of covers if the Document is in electronic form.
+Otherwise they must appear on printed covers that bracket the whole
+aggregate.
+
+
+<LI>
+TRANSLATION
+
+
+Translation is considered a kind of modification, so you may
+distribute translations of the Document under the terms of section 4.
+Replacing Invariant Sections with translations requires special
+permission from their copyright holders, but you may include
+translations of some or all Invariant Sections in addition to the
+original versions of these Invariant Sections. You may include a
+translation of this License, and all the license notices in the
+Document, and any Warranty Disclaimers, provided that you also include
+the original English version of this License and the original versions
+of those notices and disclaimers. In case of a disagreement between
+the translation and the original version of this License or a notice
+or disclaimer, the original version will prevail.
+
+
+If a section in the Document is Entitled "Acknowledgements",
+"Dedications", or "History", the requirement (section 4) to Preserve
+its Title (section 1) will typically require changing the actual
+title.
+
+
+<LI>
+TERMINATION
+
+
+You may not copy, modify, sublicense, or distribute the Document
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense, or distribute it is void, and
+will automatically terminate your rights under this License.
+
+
+However, if you cease all violation of this License, then your license
+from a particular copyright holder is reinstated (a) provisionally,
+unless and until the copyright holder explicitly and finally
+terminates your license, and (b) permanently, if the copyright holder
+fails to notify you of the violation by some reasonable means prior to
+60 days after the cessation.
+
+
+Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+
+Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License. If your rights have been terminated and not permanently
+reinstated, receipt of a copy of some or all of the same material does
+not give you any rights to use it.
+
+
+<LI>
+FUTURE REVISIONS OF THIS LICENSE
+
+
+The Free Software Foundation may publish new, revised versions
+of the GNU Free Documentation License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns. See
+<A HREF="http://www.gnu.org/copyleft/">http://www.gnu.org/copyleft/</A>.
+
+
+Each version of the License is given a distinguishing version number.
+If the Document specifies that a particular numbered version of this
+License "or any later version" applies to it, you have the option of
+following the terms and conditions either of that specified version or
+of any later version that has been published (not as a draft) by the
+Free Software Foundation. If the Document does not specify a version
+number of this License, you may choose any version ever published (not
+as a draft) by the Free Software Foundation. If the Document
+specifies that a proxy can decide which future versions of this
+License can be used, that proxy's public statement of acceptance of a
+version permanently authorizes you to choose that version for the
+Document.
+
+
+<LI>
+RELICENSING
+
+
+"Massive Multiauthor Collaboration Site" (or "MMC Site") means any
+World Wide Web server that publishes copyrightable works and also
+provides prominent facilities for anybody to edit those works. A
+public wiki that anybody can edit is an example of such a server. A
+"Massive Multiauthor Collaboration" (or "MMC") contained in the
+site means any set of copyrightable works thus published on the MMC
+site.
+
+
+"CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0
+license published by Creative Commons Corporation, a not-for-profit
+corporation with a principal place of business in San Francisco,
+California, as well as future copyleft versions of that license
+published by that same organization.
+
+
+"Incorporate" means to publish or republish a Document, in whole or
+in part, as part of another Document.
+
+
+An MMC is "eligible for relicensing" if it is licensed under this
+License, and if all works that were first published under this License
+somewhere other than this MMC, and subsequently incorporated in whole
+or in part into the MMC, (1) had no cover texts or invariant sections,
+and (2) were thus incorporated prior to November 1, 2008.
+
+
+The operator of an MMC Site may republish an MMC contained in the site
+under CC-BY-SA on the same site at any time before August 1, 2009,
+provided the MMC is eligible for relicensing.

+<H2> ADDENDUM: How to use this License for your documents </H2>
+
+
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and
+license notices just after the title page:
+
+
+<TABLE><tr><td>&nbsp;</td><td class=smallexample><pre> Copyright (C) <VAR>year</VAR> <VAR>your name</VAR>.
+ Permission is granted to copy, distribute and/or modify this document
+ under the terms of the GNU Free Documentation License, Version 1.3
+ or any later version published by the Free Software Foundation;
+ with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
+ Texts. A copy of the license is included in the section entitled ``GNU
+ Free Documentation License''.
+</pre></td></tr></table>
+
+If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
+replace the "with...Texts." line with this:
+
+
+<TABLE><tr><td>&nbsp;</td><td class=smallexample><pre> with the Invariant Sections being <VAR>list their titles</VAR>, with
+ the Front-Cover Texts being <VAR>list</VAR>, and with the Back-Cover Texts
+ being <VAR>list</VAR>.
+</pre></td></tr></table>
+
+If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+
+
+If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of
+free software license, such as the GNU General Public License,
+to permit their use in free software.

+
+1.1 Introduction to Line Editing
+================================
+
+The following paragraphs describe the notation used to represent
+keystrokes.
+
+ The text 'C-k' is read as 'Control-K' and describes the character
+produced when the <k> key is pressed while the Control key is depressed.
+
+ The text 'M-k' is read as 'Meta-K' and describes the character
+produced when the Meta key (if you have one) is depressed, and the <k>
+key is pressed. The Meta key is labeled <ALT> on many keyboards. On
+keyboards with two keys labeled <ALT> (usually to either side of the
+space bar), the <ALT> on the left side is generally set to work as a
+Meta key. The <ALT> key on the right may also be configured to work as
+a Meta key or may be configured as some other modifier, such as a
+Compose key for typing accented characters.
+
+ If you do not have a Meta or <ALT> key, or another key working as a
+Meta key, the identical keystroke can be generated by typing <ESC>
+_first_, and then typing <k>. Either process is known as "metafying"
+the <k> key.
+
+ The text 'M-C-k' is read as 'Meta-Control-k' and describes the
+character produced by "metafying" 'C-k'.
+
+ In addition, several keys have their own names. Specifically, <DEL>,
+<ESC>, <LFD>, <SPC>, <RET>, and <TAB> all stand for themselves when seen
+in this text, or in an init file (*note Readline Init File::). If your
+keyboard lacks a <LFD> key, typing <C-j> will produce the desired
+character. The <RET> key may be labeled <Return> or <Enter> on some
+keyboards.
+

+
+1.2 Readline Interaction
+========================
+
+Often during an interactive session you type in a long line of text,
+only to notice that the first word on the line is misspelled. The
+Readline library gives you a set of commands for manipulating the text
+as you type it in, allowing you to just fix your typo, and not forcing
+you to retype the majority of the line. Using these editing commands,
+you move the cursor to the place that needs correction, and delete or
+insert the text of the corrections. Then, when you are satisfied with
+the line, you simply press <RET>. You do not have to be at the end of
+the line to press <RET>; the entire line is accepted regardless of the
+location of the cursor within the line.
+
+* Menu:
+
+* Readline Bare Essentials::	The least you need to know about Readline.
+* Readline Movement Commands::	Moving about the input line.
+* Readline Killing Commands::	How to delete text, and how to get it back!
+* Readline Arguments::		Giving numeric arguments to commands.
+* Searching::			Searching through previous lines.
+
+&#x1f;
+File: rluserman.info, Node: Readline Bare Essentials, Next: Readline Movement Commands, Up: Readline Interaction
+
+1.2.1 Readline Bare Essentials
+------------------------------
+
+In order to enter characters into the line, simply type them. The typed
+character appears where the cursor was, and then the cursor moves one
+space to the right. If you mistype a character, you can use your erase
+character to back up and delete the mistyped character.
+
+ Sometimes you may mistype a character, and not notice the error until
+you have typed several other characters. In that case, you can type
+'C-b' to move the cursor to the left, and then correct your mistake.
+Afterwards, you can move the cursor to the right with 'C-f'.
+
+ When you add text in the middle of a line, you will notice that
+characters to the right of the cursor are 'pushed over' to make room for
+the text that you have inserted. Likewise, when you delete text behind
+the cursor, characters to the right of the cursor are 'pulled back' to
+fill in the blank space created by the removal of the text. A list of
+the bare essentials for editing the text of an input line follows.
+
+'C-b'
+ Move back one character.
+'C-f'
+ Move forward one character.
+<DEL> or <Backspace>
+ Delete the character to the left of the cursor.
+'C-d'
+ Delete the character underneath the cursor.
+Printing characters
+ Insert the character into the line at the cursor.
+'C-_' or 'C-x C-u'
+ Undo the last editing command. You can undo all the way back to an
+ empty line.
+
+(Depending on your configuration, the <Backspace> key be set to delete
+the character to the left of the cursor and the <DEL> key set to delete
+the character underneath the cursor, like 'C-d', rather than the
+character to the left of the cursor.)
+

+
+1.2.2 Readline Movement Commands
+--------------------------------
+
+The above table describes the most basic keystrokes that you need in
+order to do editing of the input line. For your convenience, many other
+commands have been added in addition to 'C-b', 'C-f', 'C-d', and <DEL>.
+Here are some commands for moving more rapidly about the line.
+
+'C-a'
+ Move to the start of the line.
+'C-e'
+ Move to the end of the line.
+'M-f'
+ Move forward a word, where a word is composed of letters and
+ digits.
+'M-b'
+ Move backward a word.
+'C-l'
+ Clear the screen, reprinting the current line at the top.
+
+ Notice how 'C-f' moves forward a character, while 'M-f' moves forward
+a word. It is a loose convention that control keystrokes operate on
+characters while meta keystrokes operate on words.

+1.2.3 Readline Killing Commands
+-------------------------------
+
+"Killing" text means to delete the text from the line, but to save it
+away for later use, usually by "yanking" (re-inserting) it back into the
+line. ('Cut' and 'paste' are more recent jargon for 'kill' and 'yank'.)
+
+ If the description for a command says that it 'kills' text, then you
+can be sure that you can get the text back in a different (or the same)
+place later.
+
+ When you use a kill command, the text is saved in a "kill-ring". Any
+number of consecutive kills save all of the killed text together, so
+that when you yank it back, you get it all. The kill ring is not line
+specific; the text that you killed on a previously typed line is
+available to be yanked back later, when you are typing another line.
+
+ Here is the list of commands for killing text.
+
+'C-k'
+ Kill the text from the current cursor position to the end of the
+ line.
+
+'M-d'
+ Kill from the cursor to the end of the current word, or, if between
+ words, to the end of the next word. Word boundaries are the same
+ as those used by 'M-f'.
+
+'M-<DEL>'
+ Kill from the cursor the start of the current word, or, if between
+ words, to the start of the previous word. Word boundaries are the
+ same as those used by 'M-b'.
+
+'C-w'
+ Kill from the cursor to the previous whitespace. This is different
+ than 'M-<DEL>' because the word boundaries differ.
+
+ Here is how to "yank" the text back into the line. Yanking means to
+copy the most-recently-killed text from the kill buffer.
+
+'C-y'
+ Yank the most recently killed text back into the buffer at the
+ cursor.
+
+'M-y'
+ Rotate the kill-ring, and yank the new top. You can only do this
+ if the prior command is 'C-y' or 'M-y'.
+

+
+1.2.4 Readline Arguments
+------------------------
+
+You can pass numeric arguments to Readline commands. Sometimes the
+argument acts as a repeat count, other times it is the sign of the
+argument that is significant. If you pass a negative argument to a
+command which normally acts in a forward direction, that command will
+act in a backward direction. For example, to kill text back to the
+start of the line, you might type 'M-- C-k'.
+
+ The general way to pass numeric arguments to a command is to type
+meta digits before the command. If the first 'digit' typed is a minus
+sign ('-'), then the sign of the argument will be negative. Once you
+have typed one meta digit to get the argument started, you can type the
+remainder of the digits, and then the command. For example, to give the
+'C-d' command an argument of 10, you could type 'M-1 0 C-d', which will
+delete the next ten characters on the input line.
+
+&#x1f;
+File: rluserman.info, Node: Searching, Prev: Readline Arguments, Up: Readline Interaction
+
+1.2.5 Searching for Commands in the History
+-------------------------------------------
+
+Readline provides commands for searching through the command history for
+lines containing a specified string. There are two search modes:
+"incremental" and "non-incremental".
+
+ Incremental searches begin before the user has finished typing the
+search string. As each character of the search string is typed,
+Readline displays the next entry from the history matching the string
+typed so far. An incremental search requires only as many characters as
+needed to find the desired history entry. To search backward in the
+history for a particular string, type 'C-r'. Typing 'C-s' searches
+forward through the history. The characters present in the value of the
+'isearch-terminators' variable are used to terminate an incremental
+search. If that variable has not been assigned a value, the <ESC> and
+'C-J' characters will terminate an incremental search. 'C-g' will abort
+an incremental search and restore the original line. When the search is
+terminated, the history entry containing the search string becomes the
+current line.
+
+ To find other matching entries in the history list, type 'C-r' or
+'C-s' as appropriate. This will search backward or forward in the
+history for the next entry matching the search string typed so far. Any
+other key sequence bound to a Readline command will terminate the search
+and execute that command. For instance, a <RET> will terminate the
+search and accept the line, thereby executing the command from the
+history list. A movement command will terminate the search, make the
+last line found the current line, and begin editing.
+
+ Readline remembers the last incremental search string. If two 'C-r's
+are typed without any intervening characters defining a new search
+string, any remembered search string is used.
+
+ Non-incremental searches read the entire search string before
+starting to search for matching history lines. The search string may be
+typed by the user or be part of the contents of the current line.

+
+1.3 Readline Init File
+======================
+
+Although the Readline library comes with a set of Emacs-like keybindings
+installed by default, it is possible to use a different set of
+keybindings. Any user can customize programs that use Readline by
+putting commands in an "inputrc" file, conventionally in his home
+directory. The name of this file is taken from the value of the
+environment variable 'INPUTRC'. If that variable is unset, the default
+is '~/.inputrc'. If that file does not exist or cannot be read, the
+ultimate default is '/etc/inputrc'.
+
+ When a program which uses the Readline library starts up, the init
+file is read, and the key bindings are set.
+
+ In addition, the 'C-x C-r' command re-reads this init file, thus
+incorporating any changes that you might have made to it.

+
+1.3.1 Readline Init File Syntax
+-------------------------------
+
+There are only a few basic constructs allowed in the Readline init file.
+Blank lines are ignored. Lines beginning with a '#' are comments.
+Lines beginning with a '$' indicate conditional constructs (*note
+Conditional Init Constructs::). Other lines denote variable settings
+and key bindings.
+
+Variable Settings
+ You can modify the run-time behavior of Readline by altering the
+ values of variables in Readline using the 'set' command within the
+ init file. The syntax is simple:
+
+ set VARIABLE VALUE
+
+ Here, for example, is how to change from the default Emacs-like key
+ binding to use 'vi' line editing commands:
+
+ set editing-mode vi
+
+ Variable names and values, where appropriate, are recognized
+ without regard to case. Unrecognized variable names are ignored.
+
+ Boolean variables (those that can be set to on or off) are set to
+ on if the value is null or empty, ON (case-insensitive), or 1. Any
+ other value results in the variable being set to off.
+
+ A great deal of run-time behavior is changeable with the following
+ variables.
+
+ 'bell-style'
+ Controls what happens when Readline wants to ring the terminal
+ bell. If set to 'none', Readline never rings the bell. If
+ set to 'visible', Readline uses a visible bell if one is
+ available. If set to 'audible' (the default), Readline
+ attempts to ring the terminal's bell.
+
+ 'bind-tty-special-chars'
+ If set to 'on' (the default), Readline attempts to bind the
+ control characters treated specially by the kernel's terminal
+ driver to their Readline equivalents.
+
+ 'blink-matching-paren'
+ If set to 'on', Readline attempts to briefly move the cursor
+ to an opening parenthesis when a closing parenthesis is
+ inserted. The default is 'off'.
+
+ 'colored-completion-prefix'
+ If set to 'on', when listing completions, Readline displays
+ the common prefix of the set of possible completions using a
+ different color. The color definitions are taken from the
+ value of the 'LS_COLORS' environment variable. The default is
+ 'off'.
+
+ 'colored-stats'
+ If set to 'on', Readline displays possible completions using
+ different colors to indicate their file type. The color
+ definitions are taken from the value of the 'LS_COLORS'
+ environment variable. The default is 'off'.
+
+ 'comment-begin'
+ The string to insert at the beginning of the line when the
+ 'insert-comment' command is executed. The default value is
+ '"#"'.
+
+ 'completion-display-width'
+ The number of screen columns used to display possible matches
+ when performing completion. The value is ignored if it is
+ less than 0 or greater than the terminal screen width. A
+ value of 0 will cause matches to be displayed one per line.
+ The default value is -1.
+
+ 'completion-ignore-case'
+ If set to 'on', Readline performs filename matching and
+ completion in a case-insensitive fashion. The default value
+ is 'off'.
+
+ 'completion-map-case'
+ If set to 'on', and COMPLETION-IGNORE-CASE is enabled,
+ Readline treats hyphens ('-') and underscores ('_') as
+ equivalent when performing case-insensitive filename matching
+ and completion. The default value is 'off'.
+
+ 'completion-prefix-display-length'
+ The length in characters of the common prefix of a list of
+ possible completions that is displayed without modification.
+ When set to a value greater than zero, common prefixes longer
+ than this value are replaced with an ellipsis when displaying
+ possible completions.
+
+ 'completion-query-items'
+ The number of possible completions that determines when the
+ user is asked whether the list of possibilities should be
+ displayed. If the number of possible completions is greater
+ than or equal to this value, Readline will ask whether or not
+ the user wishes to view them; otherwise, they are simply
+ listed. This variable must be set to an integer value greater
+ than or equal to 0. A negative value means Readline should
+ never ask. The default limit is '100'.
+
+ 'convert-meta'
+ If set to 'on', Readline will convert characters with the
+ eighth bit set to an ASCII key sequence by stripping the
+ eighth bit and prefixing an <ESC> character, converting them
+ to a meta-prefixed key sequence. The default value is 'on',
+ but will be set to 'off' if the locale is one that contains
+ eight-bit characters.
+
+ 'disable-completion'
+ If set to 'On', Readline will inhibit word completion.
+ Completion characters will be inserted into the line as if
+ they had been mapped to 'self-insert'. The default is 'off'.
+
+ 'echo-control-characters'
+ When set to 'on', on operating systems that indicate they
+ support it, readline echoes a character corresponding to a
+ signal generated from the keyboard. The default is 'on'.
+
+ 'editing-mode'
+ The 'editing-mode' variable controls which default set of key
+ bindings is used. By default, Readline starts up in Emacs
+ editing mode, where the keystrokes are most similar to Emacs.
+ This variable can be set to either 'emacs' or 'vi'.
+
+ 'emacs-mode-string'
+ If the SHOW-MODE-IN-PROMPT variable is enabled, this string is
+ displayed immediately before the last line of the primary
+ prompt when emacs editing mode is active. The value is
+ expanded like a key binding, so the standard set of meta- and
+ control prefixes and backslash escape sequences is available.
+ Use the '\1' and '\2' escapes to begin and end sequences of
+ non-printing characters, which can be used to embed a terminal
+ control sequence into the mode string. The default is '@'.
+
+ 'enable-bracketed-paste'
+ When set to 'On', Readline will configure the terminal in a
+ way that will enable it to insert each paste into the editing
+ buffer as a single string of characters, instead of treating
+ each character as if it had been read from the keyboard. This
+ can prevent pasted characters from being interpreted as
+ editing commands. The default is 'On'.
+
+ 'enable-keypad'
+ When set to 'on', Readline will try to enable the application
+ keypad when it is called. Some systems need this to enable
+ the arrow keys. The default is 'off'.
+
+ 'enable-meta-key'
+ When set to 'on', Readline will try to enable any meta
+ modifier key the terminal claims to support when it is called.
+ On many terminals, the meta key is used to send eight-bit
+ characters. The default is 'on'.
+
+ 'expand-tilde'
+ If set to 'on', tilde expansion is performed when Readline
+ attempts word completion. The default is 'off'.
+
+ 'history-preserve-point'
+ If set to 'on', the history code attempts to place the point
+ (the current cursor position) at the same location on each
+ history line retrieved with 'previous-history' or
+ 'next-history'. The default is 'off'.
+
+ 'history-size'
+ Set the maximum number of history entries saved in the history
+ list. If set to zero, any existing history entries are
+ deleted and no new entries are saved. If set to a value less
+ than zero, the number of history entries is not limited. By
+ default, the number of history entries is not limited. If an
+ attempt is made to set HISTORY-SIZE to a non-numeric value,
+ the maximum number of history entries will be set to 500.
+
+ 'horizontal-scroll-mode'
+ This variable can be set to either 'on' or 'off'. Setting it
+ to 'on' means that the text of the lines being edited will
+ scroll horizontally on a single screen line when they are
+ longer than the width of the screen, instead of wrapping onto
+ a new screen line. This variable is automatically set to 'on'
+ for terminals of height 1. By default, this variable is set
+ to 'off'.
+
+ 'input-meta'
+ If set to 'on', Readline will enable eight-bit input (it will
+ not clear the eighth bit in the characters it reads),
+ regardless of what the terminal claims it can support. The
+ default value is 'off', but Readline will set it to 'on' if
+ the locale contains eight-bit characters. The name
+ 'meta-flag' is a synonym for this variable.
+
+ 'isearch-terminators'
+ The string of characters that should terminate an incremental
+ search without subsequently executing the character as a
+ command (*note Searching::). If this variable has not been
+ given a value, the characters <ESC> and 'C-J' will terminate
+ an incremental search.
+
+ 'keymap'
+ Sets Readline's idea of the current keymap for key binding
+ commands. Built-in 'keymap' names are 'emacs',
+ 'emacs-standard', 'emacs-meta', 'emacs-ctlx', 'vi', 'vi-move',
+ 'vi-command', and 'vi-insert'. 'vi' is equivalent to
+ 'vi-command' ('vi-move' is also a synonym); 'emacs' is
+ equivalent to 'emacs-standard'. Applications may add
+ additional names. The default value is 'emacs'. The value of
+ the 'editing-mode' variable also affects the default keymap.
+
+ 'keyseq-timeout'
+ Specifies the duration Readline will wait for a character when
+ reading an ambiguous key sequence (one that can form a
+ complete key sequence using the input read so far, or can take
+ additional input to complete a longer key sequence). If no
+ input is received within the timeout, Readline will use the
+ shorter but complete key sequence. Readline uses this value
+ to determine whether or not input is available on the current
+ input source ('rl_instream' by default). The value is
+ specified in milliseconds, so a value of 1000 means that
+ Readline will wait one second for additional input. If this
+ variable is set to a value less than or equal to zero, or to a
+ non-numeric value, Readline will wait until another key is
+ pressed to decide which key sequence to complete. The default
+ value is '500'.
+
+ 'mark-directories'
+ If set to 'on', completed directory names have a slash
+ appended. The default is 'on'.
+
+ 'mark-modified-lines'
+ This variable, when set to 'on', causes Readline to display an
+ asterisk ('*') at the start of history lines which have been
+ modified. This variable is 'off' by default.
+
+ 'mark-symlinked-directories'
+ If set to 'on', completed names which are symbolic links to
+ directories have a slash appended (subject to the value of
+ 'mark-directories'). The default is 'off'.
+
+ 'match-hidden-files'
+ This variable, when set to 'on', causes Readline to match
+ files whose names begin with a '.' (hidden files) when
+ performing filename completion. If set to 'off', the leading
+ '.' must be supplied by the user in the filename to be
+ completed. This variable is 'on' by default.
+
+ 'menu-complete-display-prefix'
+ If set to 'on', menu completion displays the common prefix of
+ the list of possible completions (which may be empty) before
+ cycling through the list. The default is 'off'.
+
+ 'output-meta'
+ If set to 'on', Readline will display characters with the
+ eighth bit set directly rather than as a meta-prefixed escape
+ sequence. The default is 'off', but Readline will set it to
+ 'on' if the locale contains eight-bit characters.
+
+ 'page-completions'
+ If set to 'on', Readline uses an internal 'more'-like pager to
+ display a screenful of possible completions at a time. This
+ variable is 'on' by default.
+
+ 'print-completions-horizontally'
+ If set to 'on', Readline will display completions with matches
+ sorted horizontally in alphabetical order, rather than down
+ the screen. The default is 'off'.
+
+ 'revert-all-at-newline'
+ If set to 'on', Readline will undo all changes to history
+ lines before returning when 'accept-line' is executed. By
+ default, history lines may be modified and retain individual
+ undo lists across calls to 'readline'. The default is 'off'.
+
+ 'show-all-if-ambiguous'
+ This alters the default behavior of the completion functions.
+ If set to 'on', words which have more than one possible
+ completion cause the matches to be listed immediately instead
+ of ringing the bell. The default value is 'off'.
+
+ 'show-all-if-unmodified'
+ This alters the default behavior of the completion functions
+ in a fashion similar to SHOW-ALL-IF-AMBIGUOUS. If set to
+ 'on', words which have more than one possible completion
+ without any possible partial completion (the possible
+ completions don't share a common prefix) cause the matches to
+ be listed immediately instead of ringing the bell. The
+ default value is 'off'.
+
+ 'show-mode-in-prompt'
+ If set to 'on', add a string to the beginning of the prompt
+ indicating the editing mode: emacs, vi command, or vi
+ insertion. The mode strings are user-settable (e.g.,
+ EMACS-MODE-STRING). The default value is 'off'.
+
+ 'skip-completed-text'
+ If set to 'on', this alters the default completion behavior
+ when inserting a single match into the line. It's only active
+ when performing completion in the middle of a word. If
+ enabled, readline does not insert characters from the
+ completion that match characters after point in the word being
+ completed, so portions of the word following the cursor are
+ not duplicated. For instance, if this is enabled, attempting
+ completion when the cursor is after the 'e' in 'Makefile' will
+ result in 'Makefile' rather than 'Makefilefile', assuming
+ there is a single possible completion. The default value is
+ 'off'.
+
+ 'vi-cmd-mode-string'
+ If the SHOW-MODE-IN-PROMPT variable is enabled, this string is
+ displayed immediately before the last line of the primary
+ prompt when vi editing mode is active and in command mode.
+ The value is expanded like a key binding, so the standard set
+ of meta- and control prefixes and backslash escape sequences
+ is available. Use the '\1' and '\2' escapes to begin and end
+ sequences of non-printing characters, which can be used to
+ embed a terminal control sequence into the mode string. The
+ default is '(cmd)'.
+
+ 'vi-ins-mode-string'
+ If the SHOW-MODE-IN-PROMPT variable is enabled, this string is
+ displayed immediately before the last line of the primary
+ prompt when vi editing mode is active and in insertion mode.
+ The value is expanded like a key binding, so the standard set
+ of meta- and control prefixes and backslash escape sequences
+ is available. Use the '\1' and '\2' escapes to begin and end
+ sequences of non-printing characters, which can be used to
+ embed a terminal control sequence into the mode string. The
+ default is '(ins)'.
+
+ 'visible-stats'
+ If set to 'on', a character denoting a file's type is appended
+ to the filename when listing possible completions. The
+ default is 'off'.
+
+Key Bindings
+ The syntax for controlling key bindings in the init file is simple.
+ First you need to find the name of the command that you want to
+ change. The following sections contain tables of the command name,
+ the default keybinding, if any, and a short description of what the
+ command does.
+
+ Once you know the name of the command, simply place on a line in
+ the init file the name of the key you wish to bind the command to,
+ a colon, and then the name of the command. There can be no space
+ between the key name and the colon - that will be interpreted as
+ part of the key name. The name of the key can be expressed in
+ different ways, depending on what you find most comfortable.
+
+ In addition to command names, readline allows keys to be bound to a
+ string that is inserted when the key is pressed (a MACRO).
+
+ KEYNAME: FUNCTION-NAME or MACRO
+ KEYNAME is the name of a key spelled out in English. For
+ example:
+ Control-u: universal-argument
+ Meta-Rubout: backward-kill-word
+ Control-o: "> output"
+
+ In the example above, 'C-u' is bound to the function
+ 'universal-argument', 'M-DEL' is bound to the function
+ 'backward-kill-word', and 'C-o' is bound to run the macro
+ expressed on the right hand side (that is, to insert the text
+ '> output' into the line).
+
+ A number of symbolic character names are recognized while
+ processing this key binding syntax: DEL, ESC, ESCAPE, LFD,
+ NEWLINE, RET, RETURN, RUBOUT, SPACE, SPC, and TAB.
+
+ "KEYSEQ": FUNCTION-NAME or MACRO
+ KEYSEQ differs from KEYNAME above in that strings denoting an
+ entire key sequence can be specified, by placing the key
+ sequence in double quotes. Some GNU Emacs style key escapes
+ can be used, as in the following example, but the special
+ character names are not recognized.
+
+ "\C-u": universal-argument
+ "\C-x\C-r": re-read-init-file
+ "\e11~": "Function Key 1"
+
+ In the above example, 'C-u' is again bound to the function
+ 'universal-argument' (just as it was in the first example),
+ ''C-x' 'C-r'' is bound to the function 're-read-init-file',
+ and '<ESC> <> <1> <1> <~>' is bound to insert the text
+ 'Function Key 1'.
+
+ The following GNU Emacs style escape sequences are available when
+ specifying key sequences:
+
+ '\C-'
+ control prefix
+ '\M-'
+ meta prefix
+ '\e'
+ an escape character
+ '\\'
+ backslash
+ '\"'
+ <">, a double quotation mark
+ '\''
+ <'>, a single quote or apostrophe
+
+ In addition to the GNU Emacs style escape sequences, a second set
+ of backslash escapes is available:
+
+ '\a'
+ alert (bell)
+ '\b'
+ backspace
+ '\d'
+ delete
+ '\f'
+ form feed
+ '\n'
+ newline
+ '\r'
+ carriage return
+ '\t'
+ horizontal tab
+ '\v'
+ vertical tab
+ '\NNN'
+ the eight-bit character whose value is the octal value NNN
+ (one to three digits)
+ '\xHH'
+ the eight-bit character whose value is the hexadecimal value
+ HH (one or two hex digits)
+
+ When entering the text of a macro, single or double quotes must be
+ used to indicate a macro definition. Unquoted text is assumed to
+ be a function name. In the macro body, the backslash escapes
+ described above are expanded. Backslash will quote any other
+ character in the macro text, including '"' and '''. For example,
+ the following binding will make ''C-x' \' insert a single '\' into
+ the line:
+ "\C-x\\": "\\"

+
+1.3.2 Conditional Init Constructs
+---------------------------------
+
+Readline implements a facility similar in spirit to the conditional
+compilation features of the C preprocessor which allows key bindings and
+variable settings to be performed as the result of tests. There are
+four parser directives used.
+
+'$if'
+ The '$if' construct allows bindings to be made based on the editing
+ mode, the terminal being used, or the application using Readline.
+ The text of the test, after any comparison operator, extends to the
+ end of the line; unless otherwise noted, no characters are required
+ to isolate it.
+
+ 'mode'
+ The 'mode=' form of the '$if' directive is used to test
+ whether Readline is in 'emacs' or 'vi' mode. This may be used
+ in conjunction with the 'set keymap' command, for instance, to
+ set bindings in the 'emacs-standard' and 'emacs-ctlx' keymaps
+ only if Readline is starting out in 'emacs' mode.
+
+ 'term'
+ The 'term=' form may be used to include terminal-specific key
+ bindings, perhaps to bind the key sequences output by the
+ terminal's function keys. The word on the right side of the
+ '=' is tested against both the full name of the terminal and
+ the portion of the terminal name before the first '-'. This
+ allows 'sun' to match both 'sun' and 'sun-cmd', for instance.
+
+ 'version'
+ The 'version' test may be used to perform comparisons against
+ specific Readline versions. The 'version' expands to the
+ current Readline version. The set of comparison operators
+ includes '=' (and '=='), '!=', '<=', '>=', '<', and '>'. The
+ version number supplied on the right side of the operator
+ consists of a major version number, an optional decimal point,
+ and an optional minor version (e.g., '7.1'). If the minor
+ version is omitted, it is assumed to be '0'. The operator may
+ be separated from the string 'version' and from the version
+ number argument by whitespace. The following example sets a
+ variable if the Readline version being used is 7.0 or newer:
+ $if version >= 7.0
+ set show-mode-in-prompt on
+ $endif
+
+ 'application'
+ The APPLICATION construct is used to include
+ application-specific settings. Each program using the
+ Readline library sets the APPLICATION NAME, and you can test
+ for a particular value. This could be used to bind key
+ sequences to functions useful for a specific program. For
+ instance, the following command adds a key sequence that
+ quotes the current or previous word in Bash:
+ $if Bash
+ # Quote the current or previous word
+ "\C-xq": "\eb\"\ef\""
+ $endif
+
+ 'variable'
+ The VARIABLE construct provides simple equality tests for
+ Readline variables and values. The permitted comparison
+ operators are '=', '==', and '!='. The variable name must be
+ separated from the comparison operator by whitespace; the
+ operator may be separated from the value on the right hand
+ side by whitespace. Both string and boolean variables may be
+ tested. Boolean variables must be tested against the values
+ ON and OFF. The following example is equivalent to the
+ 'mode=emacs' test described above:
+ $if editing-mode == emacs
+ set show-mode-in-prompt on
+ $endif
+
+'$endif'
+ This command, as seen in the previous example, terminates an '$if'
+ command.
+
+'$else'
+ Commands in this branch of the '$if' directive are executed if the
+ test fails.
+
+'$include'
+ This directive takes a single filename as an argument and reads
+ commands and bindings from that file. For example, the following
+ directive reads from '/etc/inputrc':
+ $include /etc/inputrc

+
+&#x1f;
+File: rluserman.info, Node: Commands For Moving, Next: Commands For History, Up: Bindable Readline Commands
+
+1.4.1 Commands For Moving

+ effect if the current Readline line does not take up more than one
+ physical line or if point is not greater than the length of the
+ prompt plus the screen width.
+
+'next-screen-line ()'
+ Attempt to move point to the same physical screen column on the

+
+'clear-screen (C-l)'
+ Clear the screen, then redraw the current line, leaving the current
+ line at the top of the screen.
+
+'redraw-current-line ()'
+ Refresh the current line. By default, this is unbound.
+
+&#x1f;
+File: rluserman.info, Node: Commands For History, Next: Commands For Text, Prev: Commands For Moving, Up: Bindable Readline Commands
+
+1.4.2 Commands For Manipulating The History
+-------------------------------------------
+
+'accept-line (Newline or Return)'
+ Accept the line regardless of where the cursor is. If this line is
+ non-empty, it may be added to the history list for future recall
+ with 'add_history()'. If this line is a modified history line, the
+ history line is restored to its original state.
+
+'previous-history (C-p)'
+ Move 'back' through the history list, fetching the previous
+ command.
+
+'next-history (C-n)'
+ Move 'forward' through the history list, fetching the next command.
+
+'beginning-of-history (M-<)'
+ Move to the first line in the history.
+
+'end-of-history (M->)'
+ Move to the end of the input history, i.e., the line currently
+ being entered.
+
+'reverse-search-history (C-r)'
+ Search backward starting at the current line and moving 'up'
+ through the history as necessary. This is an incremental search.
+ This command sets the region to the matched text and activates the
+ mark.
+
+'forward-search-history (C-s)'
+ Search forward starting at the current line and moving 'down'
+ through the history as necessary. This is an incremental search.
+ This command sets the region to the matched text and activates the
+ mark.
+
+'non-incremental-reverse-search-history (M-p)'
+ Search backward starting at the current line and moving 'up'
+ through the history as necessary using a non-incremental search for
+ a string supplied by the user. The search string may match
+ anywhere in a history line.
+
+'non-incremental-forward-search-history (M-n)'
+ Search forward starting at the current line and moving 'down'
+ through the history as necessary using a non-incremental search for
+ a string supplied by the user. The search string may match
+ anywhere in a history line.
+
+'history-search-forward ()'
+ Search forward through the history for the string of characters
+ between the start of the current line and the point. The search
+ string must match at the beginning of a history line. This is a
+ non-incremental search. By default, this command is unbound.
+
+'history-search-backward ()'
+ Search backward through the history for the string of characters
+ between the start of the current line and the point. The search
+ string must match at the beginning of a history line. This is a
+ non-incremental search. By default, this command is unbound.
+
+'history-substring-search-forward ()'
+ Search forward through the history for the string of characters
+ between the start of the current line and the point. The search
+ string may match anywhere in a history line. This is a
+ non-incremental search. By default, this command is unbound.
+
+'history-substring-search-backward ()'
+ Search backward through the history for the string of characters
+ between the start of the current line and the point. The search
+ string may match anywhere in a history line. This is a
+ non-incremental search. By default, this command is unbound.
+
+'yank-nth-arg (M-C-y)'
+ Insert the first argument to the previous command (usually the
+ second word on the previous line) at point. With an argument N,
+ insert the Nth word from the previous command (the words in the
+ previous command begin with word 0). A negative argument inserts
+ the Nth word from the end of the previous command. Once the
+ argument N is computed, the argument is extracted as if the '!N'
+ history expansion had been specified.
+
+'yank-last-arg (M-. or M-_)'
+ Insert last argument to the previous command (the last word of the
+ previous history entry). With a numeric argument, behave exactly
+ like 'yank-nth-arg'. Successive calls to 'yank-last-arg' move back
+ through the history list, inserting the last word (or the word
+ specified by the argument to the first call) of each line in turn.
+ Any numeric argument supplied to these successive calls determines
+ the direction to move through the history. A negative argument
+ switches the direction through the history (back or forward). The
+ history expansion facilities are used to extract the last argument,
+ as if the '!$' history expansion had been specified.
+
+'operate-and-get-next (C-o)'
+ Accept the current line for return to the calling application as if
+ a newline had been entered, and fetch the next line relative to the
+ current line from the history for editing. A numeric argument, if
+ supplied, specifies the history entry to use instead of the current
+ line.
+
+&#x1f;
+File: rluserman.info, Node: Commands For Text, Next: Commands For Killing, Prev: Commands For History, Up: Bindable Readline Commands
+
+1.4.3 Commands For Changing Text
+--------------------------------
+
+'end-of-file (usually C-d)'
+ The character indicating end-of-file as set, for example, by
+ 'stty'. If this character is read when there are no characters on
+ the line, and point is at the beginning of the line, Readline
+ interprets it as the end of input and returns EOF.
+
+'delete-char (C-d)'
+ Delete the character at point. If this function is bound to the
+ same character as the tty EOF character, as 'C-d' commonly is, see
+ above for the effects.
+
+'backward-delete-char (Rubout)'
+ Delete the character behind the cursor. A numeric argument means
+ to kill the characters instead of deleting them.
+
+'forward-backward-delete-char ()'
+ Delete the character under the cursor, unless the cursor is at the
+ end of the line, in which case the character behind the cursor is
+ deleted. By default, this is not bound to a key.
+
+'quoted-insert (C-q or C-v)'
+ Add the next character typed to the line verbatim. This is how to
+ insert key sequences like 'C-q', for example.
+
+'tab-insert (M-<TAB>)'
+ Insert a tab character.
+
+'self-insert (a, b, A, 1, !, ...)'
+ Insert yourself.
+
+'bracketed-paste-begin ()'
+ This function is intended to be bound to the "bracketed paste"
+ escape sequence sent by some terminals, and such a binding is
+ assigned by default. It allows Readline to insert the pasted text
+ as a single unit without treating each character as if it had been
+ read from the keyboard. The characters are inserted as if each one
+ was bound to 'self-insert' instead of executing any editing
+ commands.
+
+ Bracketed paste sets the region (the characters between point and
+ the mark) to the inserted text. It uses the concept of an _active
+ mark_: when the mark is active, Readline redisplay uses the
+ terminal's standout mode to denote the region.
+
+'transpose-chars (C-t)'
+ Drag the character before the cursor forward over the character at
+ the cursor, moving the cursor forward as well. If the insertion
+ point is at the end of the line, then this transposes the last two
+ characters of the line. Negative arguments have no effect.
+
+'transpose-words (M-t)'
+ Drag the word before point past the word after point, moving point
+ past that word as well. If the insertion point is at the end of
+ the line, this transposes the last two words on the line.
+
+'upcase-word (M-u)'
+ Uppercase the current (or following) word. With a negative
+ argument, uppercase the previous word, but do not move the cursor.
+
+'downcase-word (M-l)'
+ Lowercase the current (or following) word. With a negative
+ argument, lowercase the previous word, but do not move the cursor.
+
+'capitalize-word (M-c)'
+ Capitalize the current (or following) word. With a negative
+ argument, capitalize the previous word, but do not move the cursor.
+
+'overwrite-mode ()'
+ Toggle overwrite mode. With an explicit positive numeric argument,
+ switches to overwrite mode. With an explicit non-positive numeric
+ argument, switches to insert mode. This command affects only
+ 'emacs' mode; 'vi' mode does overwrite differently. Each call to
+ 'readline()' starts in insert mode.
+
+ In overwrite mode, characters bound to 'self-insert' replace the
+ text at point rather than pushing the text to the right.
+ Characters bound to 'backward-delete-char' replace the character
+ before point with a space.
+
+ By default, this command is unbound.
+
+&#x1f;
+File: rluserman.info, Node: Commands For Killing, Next: Numeric Arguments, Prev: Commands For Text, Up: Bindable Readline Commands
+
+1.4.4 Killing And Yanking
+-------------------------
+
+'kill-line (C-k)'
+ Kill the text from point to the end of the line. With a negative
+ numeric argument, kill backward from the cursor to the beginning of
+ the current line.
+
+'backward-kill-line (C-x Rubout)'
+ Kill backward from the cursor to the beginning of the current line.
+ With a negative numeric argument, kill forward from the cursor to
+ the end of the current line.
+
+'unix-line-discard (C-u)'
+ Kill backward from the cursor to the beginning of the current line.
+
+'kill-whole-line ()'
+ Kill all characters on the current line, no matter where point is.
+ By default, this is unbound.
+
+'kill-word (M-d)'
+ Kill from point to the end of the current word, or if between
+ words, to the end of the next word. Word boundaries are the same
+ as 'forward-word'.
+
+'backward-kill-word (M-<DEL>)'
+ Kill the word behind point. Word boundaries are the same as
+ 'backward-word'.
+
+'shell-transpose-words (M-C-t)'
+ Drag the word before point past the word after point, moving point
+ past that word as well. If the insertion point is at the end of
+ the line, this transposes the last two words on the line. Word
+ boundaries are the same as 'shell-forward-word' and
+ 'shell-backward-word'.
+
+'unix-word-rubout (C-w)'
+ Kill the word behind point, using white space as a word boundary.
+ The killed text is saved on the kill-ring.
+
+'unix-filename-rubout ()'
+ Kill the word behind point, using white space and the slash
+ character as the word boundaries. The killed text is saved on the
+ kill-ring.
+
+'delete-horizontal-space ()'
+ Delete all spaces and tabs around point. By default, this is
+ unbound.
+
+'kill-region ()'
+ Kill the text in the current region. By default, this command is
+ unbound.
+
+'copy-region-as-kill ()'
+ Copy the text in the region to the kill buffer, so it can be yanked
+ right away. By default, this command is unbound.
+
+'copy-backward-word ()'
+ Copy the word before point to the kill buffer. The word boundaries
+ are the same as 'backward-word'. By default, this command is
+ unbound.
+
+'copy-forward-word ()'
+ Copy the word following point to the kill buffer. The word
+ boundaries are the same as 'forward-word'. By default, this
+ command is unbound.
+
+'yank (C-y)'
+ Yank the top of the kill ring into the buffer at point.
+
+'yank-pop (M-y)'
+ Rotate the kill-ring, and yank the new top. You can only do this
+ if the prior command is 'yank' or 'yank-pop'.
+
+&#x1f;
+File: rluserman.info, Node: Numeric Arguments, Next: Commands For Completion, Prev: Commands For Killing, Up: Bindable Readline Commands
+
+1.4.5 Specifying Numeric Arguments
+----------------------------------
+
+'digit-argument (M-0, M-1, ... M--)'
+ Add this digit to the argument already accumulating, or start a new
+ argument. 'M--' starts a negative argument.
+
+'universal-argument ()'
+ This is another way to specify an argument. If this command is
+ followed by one or more digits, optionally with a leading minus
+ sign, those digits define the argument. If the command is followed
+ by digits, executing 'universal-argument' again ends the numeric
+ argument, but is otherwise ignored. As a special case, if this
+ command is immediately followed by a character that is neither a
+ digit nor minus sign, the argument count for the next command is
+ multiplied by four. The argument count is initially one, so
+ executing this function the first time makes the argument count
+ four, a second time makes the argument count sixteen, and so on.
+ By default, this is not bound to a key.
+
+&#x1f;
+File: rluserman.info, Node: Commands For Completion, Next: Keyboard Macros, Prev: Numeric Arguments, Up: Bindable Readline Commands
+
+1.4.6 Letting Readline Type For You
+-----------------------------------
+
+'complete (<TAB>)'
+ Attempt to perform completion on the text before point. The actual
+ completion performed is application-specific. The default is
+ filename completion.
+
+'possible-completions (M-?)'
+ List the possible completions of the text before point. When
+ displaying completions, Readline sets the number of columns used
+ for display to the value of 'completion-display-width', the value
+ of the environment variable 'COLUMNS', or the screen width, in that
+ order.
+
+'insert-completions (M-*)'
+ Insert all completions of the text before point that would have
+ been generated by 'possible-completions'.
+
+'menu-complete ()'
+ Similar to 'complete', but replaces the word to be completed with a
+ single match from the list of possible completions. Repeated
+ execution of 'menu-complete' steps through the list of possible
+ completions, inserting each match in turn. At the end of the list
+ of completions, the bell is rung (subject to the setting of
+ 'bell-style') and the original text is restored. An argument of N
+ moves N positions forward in the list of matches; a negative
+ argument may be used to move backward through the list. This
+ command is intended to be bound to <TAB>, but is unbound by
+ default.
+
+'menu-complete-backward ()'
+ Identical to 'menu-complete', but moves backward through the list
+ of possible completions, as if 'menu-complete' had been given a
+ negative argument.
+
+'delete-char-or-list ()'
+ Deletes the character under the cursor if not at the beginning or
+ end of the line (like 'delete-char'). If at the end of the line,
+ behaves identically to 'possible-completions'. This command is
+ unbound by default.
+
+&#x1f;
+File: rluserman.info, Node: Keyboard Macros, Next: Miscellaneous Commands, Prev: Commands For Completion, Up: Bindable Readline Commands
+
+1.4.7 Keyboard Macros
+---------------------
+
+'start-kbd-macro (C-x ()'
+ Begin saving the characters typed into the current keyboard macro.
+
+'end-kbd-macro (C-x ))'
+ Stop saving the characters typed into the current keyboard macro
+ and save the definition.
+
+'call-last-kbd-macro (C-x e)'
+ Re-execute the last keyboard macro defined, by making the
+ characters in the macro appear as if typed at the keyboard.
+
+'print-last-kbd-macro ()'
+ Print the last keboard macro defined in a format suitable for the
+ INPUTRC file.
+
+&#x1f;
+File: rluserman.info, Node: Miscellaneous Commands, Prev: Keyboard Macros, Up: Bindable Readline Commands
+
+1.4.8 Some Miscellaneous Commands
+---------------------------------
+
+'re-read-init-file (C-x C-r)'
+ Read in the contents of the INPUTRC file, and incorporate any
+ bindings or variable assignments found there.
+
+'abort (C-g)'
+ Abort the current editing command and ring the terminal's bell
+ (subject to the setting of 'bell-style').
+
+'do-lowercase-version (M-A, M-B, M-X, ...)'
+ If the metafied character X is upper case, run the command that is
+ bound to the corresponding metafied lower case character. The
+ behavior is undefined if X is already lower case.
+
+'prefix-meta (<ESC>)'
+ Metafy the next character typed. This is for keyboards without a
+ meta key. Typing '<ESC> f' is equivalent to typing 'M-f'.
+
+'undo (C-_ or C-x C-u)'
+ Incremental undo, separately remembered for each line.
+
+'revert-line (M-r)'
+ Undo all changes made to this line. This is like executing the
+ 'undo' command enough times to get back to the beginning.
+
+'tilde-expand (M-~)'
+ Perform tilde expansion on the current word.
+
+'set-mark (C-@)'
+ Set the mark to the point. If a numeric argument is supplied, the
+ mark is set to that position.
+
+'exchange-point-and-mark (C-x C-x)'
+ Swap the point with the mark. The current cursor position is set
+ to the saved position, and the old cursor position is saved as the
+ mark.
+
+'character-search (C-)'
+ A character is read and point is moved to the next occurrence of
+ that character. A negative count searches for previous
+ occurrences.
+
+'character-search-backward (M-C-)'
+ A character is read and point is moved to the previous occurrence
+ of that character. A negative count searches for subsequent
+ occurrences.
+
+'skip-csi-sequence ()'
+ Read enough characters to consume a multi-key sequence such as
+ those defined for keys like Home and End. Such sequences begin
+ with a Control Sequence Indicator (CSI), usually ESC-. If this
+ sequence is bound to "\e", keys producing such sequences will have
+ no effect unless explicitly bound to a readline command, instead of
+ inserting stray characters into the editing buffer. This is
+ unbound by default, but usually bound to ESC-.
+
+'insert-comment (M-#)'
+ Without a numeric argument, the value of the 'comment-begin'
+ variable is inserted at the beginning of the current line. If a
+ numeric argument is supplied, this command acts as a toggle: if the
+ characters at the beginning of the line do not match the value of
+ 'comment-begin', the value is inserted, otherwise the characters in
+ 'comment-begin' are deleted from the beginning of the line. In
+ either case, the line is accepted as if a newline had been typed.
+
+'dump-functions ()'
+ Print all of the functions and their key bindings to the Readline
+ output stream. If a numeric argument is supplied, the output is
+ formatted in such a way that it can be made part of an INPUTRC
+ file. This command is unbound by default.
+
+'dump-variables ()'
+ Print all of the settable variables and their values to the
+ Readline output stream. If a numeric argument is supplied, the
+ output is formatted in such a way that it can be made part of an
+ INPUTRC file. This command is unbound by default.
+
+'dump-macros ()'
+ Print all of the Readline key sequences bound to macros and the
+ strings they output. If a numeric argument is supplied, the output
+ is formatted in such a way that it can be made part of an INPUTRC
+ file. This command is unbound by default.
+
+'emacs-editing-mode (C-e)'
+ When in 'vi' command mode, this causes a switch to 'emacs' editing
+ mode.
+
+'vi-editing-mode (M-C-j)'
+ When in 'emacs' editing mode, this causes a switch to 'vi' editing
+ mode.
+
+&#x1f;
+File: rluserman.info, Node: Readline vi Mode, Prev: Bindable Readline Commands, Up: Command Line Editing
+
+1.5 Readline vi Mode
+====================
+
+While the Readline library does not have a full set of 'vi' editing
+functions, it does contain enough to allow simple editing of the line.
+The Readline 'vi' mode behaves as specified in the POSIX standard.
+
+ In order to switch interactively between 'emacs' and 'vi' editing
+modes, use the command 'M-C-j' (bound to emacs-editing-mode when in 'vi'
+mode and to vi-editing-mode in 'emacs' mode). The Readline default is
+'emacs' mode.
+
+ When you enter a line in 'vi' mode, you are already placed in
+'insertion' mode, as if you had typed an 'i'. Pressing <ESC> switches
+you into 'command' mode, where you can edit the text of the line with
+the standard 'vi' movement keys, move to previous history lines with 'k'
+and subsequent lines with 'j', and so forth.

+ Document or a portion of it, either copied verbatim, or with
+ modifications and/or translated into another language.
+
+ A "Secondary Section" is a named appendix or a front-matter section
+ of the Document that deals exclusively with the relationship of the
+ publishers or authors of the Document to the Document's overall
+ subject (or to related matters) and contains nothing that could
+ fall directly within that overall subject. (Thus, if the Document
+ is in part a textbook of mathematics, a Secondary Section may not
+ explain any mathematics.) The relationship could be a matter of
+ historical connection with the subject or with related matters, or
+ of legal, commercial, philosophical, ethical or political position
+ regarding them.
+
+ The "Invariant Sections" are certain Secondary Sections whose
+ titles are designated, as being those of Invariant Sections, in the
+ notice that says that the Document is released under this License.
+ If a section does not fit the above definition of Secondary then it
+ is not allowed to be designated as Invariant. The Document may
+ contain zero Invariant Sections. If the Document does not identify
+ any Invariant Sections then there are none.
+
+ The "Cover Texts" are certain short passages of text that are
+ listed, as Front-Cover Texts or Back-Cover Texts, in the notice
+ that says that the Document is released under this License. A
+ Front-Cover Text may be at most 5 words, and a Back-Cover Text may
+ be at most 25 words.
+
+ A "Transparent" copy of the Document means a machine-readable copy,
+ represented in a format whose specification is available to the
+ general public, that is suitable for revising the document
+ straightforwardly with generic text editors or (for images composed
+ of pixels) generic paint programs or (for drawings) some widely
+ available drawing editor, and that is suitable for input to text
+ formatters or for automatic translation to a variety of formats
+ suitable for input to text formatters. A copy made in an otherwise
+ Transparent file format whose markup, or absence of markup, has
+ been arranged to thwart or discourage subsequent modification by
+ readers is not Transparent. An image format is not Transparent if
+ used for any substantial amount of text. A copy that is not
+ "Transparent" is called "Opaque".
+
+ Examples of suitable formats for Transparent copies include plain
+ ASCII without markup, Texinfo input format, LaTeX input format,
+ SGML or XML using a publicly available DTD, and standard-conforming
+ simple HTML, PostScript or PDF designed for human modification.
+ Examples of transparent image formats include PNG, XCF and JPG.
+ Opaque formats include proprietary formats that can be read and
+ edited only by proprietary word processors, SGML or XML for which
+ the DTD and/or processing tools are not generally available, and
+ the machine-generated HTML, PostScript or PDF produced by some word
+ processors for output purposes only.
+
+ The "Title Page" means, for a printed book, the title page itself,
+ plus such following pages as are needed to hold, legibly, the
+ material this License requires to appear in the title page. For
+ works in formats which do not have any title page as such, "Title
+ Page" means the text near the most prominent appearance of the
+ work's title, preceding the beginning of the body of the text.
+
+ The "publisher" means any person or entity that distributes copies
+ of the Document to the public.
+
+ A section "Entitled XYZ" means a named subunit of the Document
+ whose title either is precisely XYZ or contains XYZ in parentheses
+ following text that translates XYZ in another language. (Here XYZ
+ stands for a specific section name mentioned below, such as
+ "Acknowledgements", "Dedications", "Endorsements", or "History".)
+ To "Preserve the Title" of such a section when you modify the
+ Document means that it remains a section "Entitled XYZ" according
+ to this definition.
+
+ The Document may include Warranty Disclaimers next to the notice
+ which states that this License applies to the Document. These
+ Warranty Disclaimers are considered to be included by reference in
+ this License, but only as regards disclaiming warranties: any other
+ implication that these Warranty Disclaimers may have is void and
+ has no effect on the meaning of this License.
+
+ 2. VERBATIM COPYING
+
+ You may copy and distribute the Document in any medium, either
+ commercially or noncommercially, provided that this License, the
+ copyright notices, and the license notice saying this License
+ applies to the Document are reproduced in all copies, and that you
+ add no other conditions whatsoever to those of this License. You
+ may not use technical measures to obstruct or control the reading
+ or further copying of the copies you make or distribute. However,
+ you may accept compensation in exchange for copies. If you
+ distribute a large enough number of copies you must also follow the
+ conditions in section 3.
+
+ You may also lend copies, under the same conditions stated above,
+ and you may publicly display copies.
+
+ 3. COPYING IN QUANTITY
+
+ If you publish printed copies (or copies in media that commonly
+ have printed covers) of the Document, numbering more than 100, and
+ the Document's license notice requires Cover Texts, you must
+ enclose the copies in covers that carry, clearly and legibly, all
+ these Cover Texts: Front-Cover Texts on the front cover, and
+ Back-Cover Texts on the back cover. Both covers must also clearly
+ and legibly identify you as the publisher of these copies. The
+ front cover must present the full title with all words of the title
+ equally prominent and visible. You may add other material on the
+ covers in addition. Copying with changes limited to the covers, as
+ long as they preserve the title of the Document and satisfy these
+ conditions, can be treated as verbatim copying in other respects.
+
+ If the required texts for either cover are too voluminous to fit
+ legibly, you should put the first ones listed (as many as fit
+ reasonably) on the actual cover, and continue the rest onto
+ adjacent pages.
+
+ If you publish or distribute Opaque copies of the Document
+ numbering more than 100, you must either include a machine-readable
+ Transparent copy along with each Opaque copy, or state in or with
+ each Opaque copy a computer-network location from which the general
+ network-using public has access to download using public-standard
+ network protocols a complete Transparent copy of the Document, free
+ of added material. If you use the latter option, you must take
+ reasonably prudent steps, when you begin distribution of Opaque
+ copies in quantity, to ensure that this Transparent copy will
+ remain thus accessible at the stated location until at least one
+ year after the last time you distribute an Opaque copy (directly or
+ through your agents or retailers) of that edition to the public.
+
+ It is requested, but not required, that you contact the authors of
+ the Document well before redistributing any large number of copies,
+ to give them a chance to provide you with an updated version of the
+ Document.
+
+ 4. MODIFICATIONS
+
+ You may copy and distribute a Modified Version of the Document
+ under the conditions of sections 2 and 3 above, provided that you
+ release the Modified Version under precisely this License, with the
+ Modified Version filling the role of the Document, thus licensing
+ distribution and modification of the Modified Version to whoever
+ possesses a copy of it. In addition, you must do these things in
+ the Modified Version:
+
+ A. Use in the Title Page (and on the covers, if any) a title
+ distinct from that of the Document, and from those of previous
+ versions (which should, if there were any, be listed in the
+ History section of the Document). You may use the same title
+ as a previous version if the original publisher of that
+ version gives permission.
+
+ B. List on the Title Page, as authors, one or more persons or
+ entities responsible for authorship of the modifications in
+ the Modified Version, together with at least five of the
+ principal authors of the Document (all of its principal
+ authors, if it has fewer than five), unless they release you
+ from this requirement.
+
+ C. State on the Title page the name of the publisher of the
+ Modified Version, as the publisher.
+
+ D. Preserve all the copyright notices of the Document.
+
+ E. Add an appropriate copyright notice for your modifications
+ adjacent to the other copyright notices.
+
+ F. Include, immediately after the copyright notices, a license
+ notice giving the public permission to use the Modified
+ Version under the terms of this License, in the form shown in
+ the Addendum below.
+
+ G. Preserve in that license notice the full lists of Invariant
+ Sections and required Cover Texts given in the Document's
+ license notice.
+
+ H. Include an unaltered copy of this License.
+
+ I. Preserve the section Entitled "History", Preserve its Title,
+ and add to it an item stating at least the title, year, new
+ authors, and publisher of the Modified Version as given on the
+ Title Page. If there is no section Entitled "History" in the
+ Document, create one stating the title, year, authors, and
+ publisher of the Document as given on its Title Page, then add
+ an item describing the Modified Version as stated in the
+ previous sentence.
+
+ J. Preserve the network location, if any, given in the Document
+ for public access to a Transparent copy of the Document, and
+ likewise the network locations given in the Document for
+ previous versions it was based on. These may be placed in the
+ "History" section. You may omit a network location for a work
+ that was published at least four years before the Document
+ itself, or if the original publisher of the version it refers
+ to gives permission.
+
+ K. For any section Entitled "Acknowledgements" or "Dedications",
+ Preserve the Title of the section, and preserve in the section
+ all the substance and tone of each of the contributor
+ acknowledgements and/or dedications given therein.
+
+ L. Preserve all the Invariant Sections of the Document, unaltered
+ in their text and in their titles. Section numbers or the
+ equivalent are not considered part of the section titles.
+
+ M. Delete any section Entitled "Endorsements". Such a section
+ may not be included in the Modified Version.
+
+ N. Do not retitle any existing section to be Entitled
+ "Endorsements" or to conflict in title with any Invariant
+ Section.
+
+ O. Preserve any Warranty Disclaimers.
+
+ If the Modified Version includes new front-matter sections or
+ appendices that qualify as Secondary Sections and contain no
+ material copied from the Document, you may at your option designate
+ some or all of these sections as invariant. To do this, add their
+ titles to the list of Invariant Sections in the Modified Version's
+ license notice. These titles must be distinct from any other
+ section titles.
+
+ You may add a section Entitled "Endorsements", provided it contains
+ nothing but endorsements of your Modified Version by various
+ parties--for example, statements of peer review or that the text
+ has been approved by an organization as the authoritative
+ definition of a standard.
+
+ You may add a passage of up to five words as a Front-Cover Text,
+ and a passage of up to 25 words as a Back-Cover Text, to the end of
+ the list of Cover Texts in the Modified Version. Only one passage
+ of Front-Cover Text and one of Back-Cover Text may be added by (or
+ through arrangements made by) any one entity. If the Document
+ already includes a cover text for the same cover, previously added
+ by you or by arrangement made by the same entity you are acting on
+ behalf of, you may not add another; but you may replace the old
+ one, on explicit permission from the previous publisher that added
+ the old one.
+
+ The author(s) and publisher(s) of the Document do not by this
+ License give permission to use their names for publicity for or to
+ assert or imply endorsement of any Modified Version.
+
+ 5. COMBINING DOCUMENTS
+
+ You may combine the Document with other documents released under
+ this License, under the terms defined in section 4 above for
+ modified versions, provided that you include in the combination all
+ of the Invariant Sections of all of the original documents,
+ unmodified, and list them all as Invariant Sections of your
+ combined work in its license notice, and that you preserve all
+ their Warranty Disclaimers.
+
+ The combined work need only contain one copy of this License, and
+ multiple identical Invariant Sections may be replaced with a single
+ copy. If there are multiple Invariant Sections with the same name
+ but different contents, make the title of each such section unique
+ by adding at the end of it, in parentheses, the name of the
+ original author or publisher of that section if known, or else a
+ unique number. Make the same adjustment to the section titles in
+ the list of Invariant Sections in the license notice of the
+ combined work.
+
+ In the combination, you must combine any sections Entitled
+ "History" in the various original documents, forming one section
+ Entitled "History"; likewise combine any sections Entitled
+ "Acknowledgements", and any sections Entitled "Dedications". You
+ must delete all sections Entitled "Endorsements."
+
+ 6. COLLECTIONS OF DOCUMENTS
+
+ You may make a collection consisting of the Document and other
+ documents released under this License, and replace the individual
+ copies of this License in the various documents with a single copy
+ that is included in the collection, provided that you follow the
+ rules of this License for verbatim copying of each of the documents
+ in all other respects.
+
+ You may extract a single document from such a collection, and
+ distribute it individually under this License, provided you insert
+ a copy of this License into the extracted document, and follow this
+ License in all other respects regarding verbatim copying of that
+ document.
+
+ 7. AGGREGATION WITH INDEPENDENT WORKS
+
+ A compilation of the Document or its derivatives with other
+ separate and independent documents or works, in or on a volume of a
+ storage or distribution medium, is called an "aggregate" if the
+ copyright resulting from the compilation is not used to limit the
+ legal rights of the compilation's users beyond what the individual
+ works permit. When the Document is included in an aggregate, this
+ License does not apply to the other works in the aggregate which
+ are not themselves derivative works of the Document.
+
+ If the Cover Text requirement of section 3 is applicable to these
+ copies of the Document, then if the Document is less than one half
+ of the entire aggregate, the Document's Cover Texts may be placed
+ on covers that bracket the Document within the aggregate, or the
+ electronic equivalent of covers if the Document is in electronic
+ form. Otherwise they must appear on printed covers that bracket
+ the whole aggregate.
+
+ 8. TRANSLATION
+
+ Translation is considered a kind of modification, so you may
+ distribute translations of the Document under the terms of section
+ 4. Replacing Invariant Sections with translations requires special
+ permission from their copyright holders, but you may include
+ translations of some or all Invariant Sections in addition to the
+ original versions of these Invariant Sections. You may include a
+ translation of this License, and all the license notices in the
+ Document, and any Warranty Disclaimers, provided that you also
+ include the original English version of this License and the
+ original versions of those notices and disclaimers. In case of a
+ disagreement between the translation and the original version of
+ this License or a notice or disclaimer, the original version will
+ prevail.
+
+ If a section in the Document is Entitled "Acknowledgements",
+ "Dedications", or "History", the requirement (section 4) to
+ Preserve its Title (section 1) will typically require changing the
+ actual title.
+
+ 9. TERMINATION
+
+ You may not copy, modify, sublicense, or distribute the Document
+ except as expressly provided under this License. Any attempt
+ otherwise to copy, modify, sublicense, or distribute it is void,
+ and will automatically terminate your rights under this License.
+
+ However, if you cease all violation of this License, then your
+ license from a particular copyright holder is reinstated (a)
+ provisionally, unless and until the copyright holder explicitly and
+ finally terminates your license, and (b) permanently, if the
+ copyright holder fails to notify you of the violation by some
+ reasonable means prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+ reinstated permanently if the copyright holder notifies you of the
+ violation by some reasonable means, this is the first time you have
+ received notice of violation of this License (for any work) from
+ that copyright holder, and you cure the violation prior to 30 days
+ after your receipt of the notice.
+
+ Termination of your rights under this section does not terminate
+ the licenses of parties who have received copies or rights from you
+ under this License. If your rights have been terminated and not
+ permanently reinstated, receipt of a copy of some or all of the
+ same material does not give you any rights to use it.
+
+ 10. FUTURE REVISIONS OF THIS LICENSE
+
+ The Free Software Foundation may publish new, revised versions of
+ the GNU Free Documentation License from time to time. Such new
+ versions will be similar in spirit to the present version, but may
+ differ in detail to address new problems or concerns. See
+ <http://www.gnu.org/copyleft/>.
+
+ Each version of the License is given a distinguishing version
+ number. If the Document specifies that a particular numbered
+ version of this License "or any later version" applies to it, you
+ have the option of following the terms and conditions either of
+ that specified version or of any later version that has been
+ published (not as a draft) by the Free Software Foundation. If the
+ Document does not specify a version number of this License, you may
+ choose any version ever published (not as a draft) by the Free
+ Software Foundation. If the Document specifies that a proxy can
+ decide which future versions of this License can be used, that
+ proxy's public statement of acceptance of a version permanently
+ authorizes you to choose that version for the Document.
+
+ 11. RELICENSING
+
+ "Massive Multiauthor Collaboration Site" (or "MMC Site") means any
+ World Wide Web server that publishes copyrightable works and also
+ provides prominent facilities for anybody to edit those works. A
+ public wiki that anybody can edit is an example of such a server.
+ A "Massive Multiauthor Collaboration" (or "MMC") contained in the
+ site means any set of copyrightable works thus published on the MMC
+ site.
+
+ "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0
+ license published by Creative Commons Corporation, a not-for-profit
+ corporation with a principal place of business in San Francisco,
+ California, as well as future copyleft versions of that license
+ published by that same organization.
+
+ "Incorporate" means to publish or republish a Document, in whole or
+ in part, as part of another Document.
+
+ An MMC is "eligible for relicensing" if it is licensed under this
+ License, and if all works that were first published under this
+ License somewhere other than this MMC, and subsequently
+ incorporated in whole or in part into the MMC, (1) had no cover
+ texts or invariant sections, and (2) were thus incorporated prior
+ to November 1, 2008.
+
+ The operator of an MMC Site may republish an MMC contained in the
+ site under CC-BY-SA on the same site at any time before August 1,
+ 2009, provided the MMC is eligible for relicensing.
+
+ADDENDUM: How to use this License for your documents
+====================================================
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and license
+notices just after the title page:
+
+ Copyright (C) YEAR YOUR NAME.
+ Permission is granted to copy, distribute and/or modify this document
+ under the terms of the GNU Free Documentation License, Version 1.3
+ or any later version published by the Free Software Foundation;
+ with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
+ Texts. A copy of the license is included in the section entitled ``GNU
+ Free Documentation License''.
+
+ If you have Invariant Sections, Front-Cover Texts and Back-Cover
+Texts, replace the "with...Texts." line with this:
+
+ with the Invariant Sections being LIST THEIR TITLES, with
+ the Front-Cover Texts being LIST, and with the Back-Cover Texts
+ being LIST.
+
+ If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+
+ If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of free
+software license, such as the GNU General Public License, to permit
+their use in free software.

+Usage: $program OPTION... FILE...
+ or: texi2pdf OPTION... FILE...
+ or: pdftexi2dvi OPTION... FILE...
+
+Run each Texinfo or (La)TeX FILE through TeX in turn until all
+cross-references are resolved, building all indices. The directory
+containing each FILE is searched for included files. The suffix of FILE
+is used to determine its language ((La)TeX or Texinfo). To process
+(e)plain TeX files, set the environment variable LATEX=tex.
+
+When invoked as \`texi2pdf' or given the option --pdf generate PDF output.
+Otherwise, generate DVI.
+
+General options:
+ -D, --debug turn on shell debugging (set -x)
+ -h, --help display this help and exit successfully
+ -o, --output=OFILE leave output in OFILE; only one input FILE is allowed
+ -q, --quiet no output unless errors
+ -v, --version display version information and exit successfully
+ -V, --verbose report on what is done
+ --max-iterations=N don't process files more than N times $max_iters
+ --mostly-clean remove auxiliary files or directories from
+ previous runs (but not the output)
+
+Output format:
+ --dvi output a DVI file default
+ --dvipdf output a PDF file via DVI (using a dvi-to-pdf program)
+ --html output an HTML file from LaTeX, using HeVeA
+ --info output an Info file from LaTeX, using HeVeA
+ -p, --pdf use pdftex or pdflatex for processing
+ --ps output a PostScript file via DVI (using dvips)
+ --text output a plain text file from LaTeX, using HeVeA
+
+TeX tuning:
+ -E, --expand macro expansion using makeinfo
+ -I DIR search DIR for Texinfo files
+ -l, --language=LANG specify LANG for FILE, either latex or texinfo
+ --no-line-error do not pass --file-line-error to TeX
+ --shell-escape pass --shell-escape to TeX
+ --src-specials pass --src-specials to TeX
+ --translate-file=FILE use given charset translation file for TeX
+ -t, --command=CMD insert CMD in copy of input file
+
+Build modes:
+ --build=MODE specify the treatment of auxiliary files $build_mode
+ --tidy same as --build=tidy
+ -c, --clean same as --build=clean
+ --build-dir=DIR specify where the tidy compilation is performed;
+ implies --tidy;
+ defaults to TEXI2DVI_BUILD_DIRECTORY $build_dir
+
+The MODE specifies where the TeX compilation takes place, and, as a
+consequence, how auxiliary files are treated. The build mode can also
+be set using the environment variable TEXI2DVI_BUILD_MODE.
+
+Valid values of MODE are:
+ \`local' compile in the current directory, leaving all the auxiliary
+ files around. This is the traditional TeX use.
+ \`tidy' compile in a local *.t2d directory, where the auxiliary files
+ are left. Output files are copied back to the original file.
+ \`clean' same as \`tidy', but remove the auxiliary directory afterwards.
+ Every compilation therefore requires the full cycle.
+
+The values of these environment variables are used to run the
+corresponding commands, if they are set:
+
+ BIBER BIBTEX DVIPDF DVIPS EGREP HEVEA LATEX MAKEINDEX MAKEINFO
+ PDFLATEX PDFTEX SED T4HT TEX TEX4HT TEXINDEX TEXINDY THUMBPDF_CMD
+
+Regarding --dvipdf, if DVIPDF is not set in the environment, the
+following programs are looked for (in this order): dvipdfmx dvipdfm
+dvipdf dvi2pdf dvitopdf.
+
+If Texinfo is installed on your site, then the command
+
+ info texi2dvi
+ 
+should give you access to more documentation.

+% Please try the latest version of texinfo.tex before submitting bug

+% http://ftpmirror.gnu.org/texinfo/ (same, via a mirror), or

+%
+% To process a Texinfo manual with TeX, it's most reliable to use the
+% texi2dvi shell script that comes with the distribution. For a simple
+% manual foo.texi, however, you can get away with this:
+% tex foo.texi
+% texindex foo.??
+% tex foo.texi
+% tex foo.texi
+% dvips foo.dvi -o # or whatever; this makes foo.ps.
+% The extra TeX runs get the cross-reference information correct.
+% Sometimes one run after texindex suffices, and sometimes you need more
+% than two; texi2dvi does it as many times as necessary.
+%
+% It is possible to adapt texinfo.tex for other languages, to some
+% extent. You can get the existing language-specific files from the
+% full Texinfo distribution.

+% Output a mark which sets \thischapter, \thissection and \thiscolor.

+% A mark contains a subexpression of the \ifcase ... \fi construct.

+%
+% Another complication is to let the user choose whether \thischapter

+% described on page 260 of The TeXbook. It involves outputting two

+% @multitable macros
+% Amy Hendrickson, 8/18/94, 3/6/96
+%
+% @multitable ... @end multitable will make as many columns as desired.
+% Contents of each column will wrap at width given in preamble. Width
+% can be specified either with sample text given in a template line,
+% or in percent of \hsize, the current width of text on page.
+
+% Table can continue over pages but will only break between lines.
+
+% To make preamble:
+%
+% Either define widths of columns in terms of percent of \hsize:
+% @multitable @columnfractions .25 .3 .45
+% @item ...
+%
+% Numbers following @columnfractions are the percent of the total
+% current hsize to be used for each column. You may use as many
+% columns as desired.
+
+
+% Or use a template:
+% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+% @item ...
+% using the widest term desired in each column.
+
+% Each new table line starts with @item, each subsequent new column
+% starts with @tab. Empty columns may be produced by supplying @tab's
+% with nothing between them for as many times as empty columns are needed,
+% ie, @tab@tab@tab will produce two empty columns.
+
+% @item, @tab do not need to be on their own lines, but it will not hurt
+% if they are.
+
+% Sample multitable:
+
+% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+% @item first col stuff @tab second col stuff @tab third col
+% @item
+% first col stuff
+% @tab
+% second col stuff
+% @tab
+% third col
+% @item first col stuff @tab second col stuff
+% @tab Many paragraphs of text may be used in any column.
+%
+% They will wrap at the width determined by the template.
+% @item@tab@tab This will be in third column.
+% @end multitable
+
+% Default dimensions may be reset by user.
+% @multitableparskip is vertical space between paragraphs in table.
+% @multitableparindent is paragraph indent in table.
+% @multitablecolmargin is horizontal space to be left between columns.
+% @multitablelinespace is space to leave between table items, baseline
+% to baseline.
+% 0pt means it depends on current normal line spacing.

+Subject: new readline example
+Message-ID: <14094.12094.527305.199695@mrclean.Stanford.EDU>
+
+Chet,
+
+I've been using readline 4.0. Specifically, I've been using the perl
+version Term::ReadLine::Gnu. It works great.
+
+Anyway, I've been playing around the alternate interface and I wanted
+to contribute a little C program, callback.c, to you that you could
+use as an example of the alternate interface in the /examples
+directory of the readline distribution.
+
+My example shows how, using the alternate interface, you can
+interactively change the prompt (which is very nice imo). Also, I
+point out that you must roll your own terminal setting when using the
+alternate interface because readline depreps (using your parlance) the
+terminal while in the user callback. I try to demostrate what I mean
+with an example. I've included the program below.
+
+To compile, I just put the program in the examples directory and made
+the appropriate changes to the EXECUTABLES and OBJECTS line and added
+an additional target 'callback'.
+
+I compiled on my Sun Solaris2.6 box using Sun's cc.
+
+Let me know what you think.

+/* This little examples demonstrates the alternate interface to using readline.
+ * In the alternate interface, the user maintains control over program flow and
+ * only calls readline when STDIN is readable. Using the alternate interface,
+ * you can do anything else while still using readline (like talking to a
+ * network or another program) without blocking.
+ *
+ * Specifically, this program highlights two importants features of the
+ * alternate interface. The first is the ability to interactively change the
+ * prompt, which can't be done using the regular interface since rl_prompt is
+ * read-only.
+ * 
+ * The second feature really highlights a subtle point when using the alternate
+ * interface. That is, readline will not alter the terminal when inside your
+ * callback handler. So let's so, your callback executes a user command that
+ * takes a non-trivial amount of time to complete (seconds). While your
+ * executing the command, the user continues to type keystrokes and expects them
+ * to be re-echoed on the new prompt when it returns. Unfortunately, the default
+ * terminal configuration doesn't do this. After the prompt returns, the user

+Subject: fgets(stdin) --> readline() redirector
+To: chet@po.cwru.edu
+
+Hi Chet,
+
+Here is something you may find useful enough to include in the readline
+distribution. It is a shared library that redirects calls to fgets(stdin)
+to readline() via LD_PRELOAD, and it supports a custom prompt and list of
+command names. Many people have asked me for this file, so I thought I'd
+pass it your way in hope of just including it with readline to begin with.
+
+Best Regards,
+
+-Harold
+*/
+
+/******************************************************************************
+*******************************************************************************
+ 
+ FILE NAME: fgets.c TARGET: libfgets.so
+ AUTHOR: Harold Levy VERSION: 1.0
+ hlevy@synopsys.com
+ 
+ ABSTRACT: Customize fgets() behavior via LD_PRELOAD in the following ways:
+ 
+ -- If fgets(stdin) is called, redirect to GNU readline() to obtain
+ command-line editing, file-name completion, history, etc.
+ 
+ -- A list of commands for command-name completion can be configured by
+ setting the environment-variable FGETS_COMMAND_FILE to a file containing
+ the list of commands to be used.
+ 
+ -- Command-line editing with readline() works best when the prompt string
+ is known; you can set this with the FGETS_PROMPT environment variable.
+ 
+ -- There special strings that libfgets will interpret as internal commands:
+ 
+ _fgets_reset_ reset the command list
+ 
+ _fgets_dump_ dump status
+ 
+ _fgets_debug_ toggle debug messages
+
+ HOW TO BUILD: Here are examples of how to build libfgets.so on various
+ platforms; you will have to add -I and -L flags to configure access to
+ the readline header and library files.
+
+ (32-bit builds with gcc)
+ AIX: gcc -fPIC fgets.c -shared -o libfgets.so -lc -ldl -lreadline -ltermcap
+ HP-UX: gcc -fPIC fgets.c -shared -o libfgets.so -lc -ldld -lreadline
+ Linux: gcc -fPIC fgets.c -shared -o libfgets.so -lc -ldl -lreadline
+ SunOS: gcc -fPIC fgets.c -shared -o libfgets.so -lc -ldl -lgen -lreadline
+
+ (64-bit builds without gcc)
+ SunOS: SUNWspro/bin/cc -D_LARGEFILE64_SOURCE=1 -xtarget=ultra -xarch=v9 \
+ -KPIC fgets.c -Bdynamic -lc -ldl -lgen -ltermcap -lreadline
+ 
+ HOW TO USE: Different operating systems have different levels of support
+ for the LD_PRELOAD concept. The generic method for 32-bit platforms is to
+ put libtermcap.so, libfgets.so, and libreadline.so (with absolute paths)
+ in the LD_PRELOAD environment variable, and to put their parent directories
+ in the LD_LIBRARY_PATH environment variable. Unfortunately there is no
+ generic method for 64-bit platforms; e.g. for 64-bit SunOS, you would have
+ to build both 32-bit and 64-bit libfgets and libreadline libraries, and
+ use the LD_FLAGS_32 and LD_FLAGS_64 environment variables with preload and
+ library_path configurations (a mix of 32-bit and 64-bit calls are made under
+ 64-bit SunOS).
+ 
+ EXAMPLE WRAPPER: Here is an example shell script wrapper around the
+ program "foo" that uses fgets() for command-line input:
+
+ #!/bin/csh
+ #### replace this with the libtermcap.so directory:
+ set dir1 = "/usr/lib"
+ #### replace this with the libfgets.so directory:
+ set dir2 = "/usr/fgets"
+ #### replace this with the libreadline.so directory:
+ set dir3 = "/usr/local/lib"
+ set lib1 = "${dir1}/libtermcap.so"
+ set lib2 = "${dir2}/libfgets.so"
+ set lib3 = "${dir3}/libreadline.so"
+ if ( "${?LD_PRELOAD}" ) then
+ setenv LD_PRELOAD "${lib1}:${lib2}:${lib3}:${LD_PRELOAD}"
+ else
+ setenv LD_PRELOAD "${lib1}:${lib2}:${lib3}"
+ endif
+ if ( "${?LD_LIBRARY_PATH}" ) then
+ setenv LD_LIBRARY_PATH "${dir1}:${dir2}:${dir3}:${LD_LIBRARY_PATH}"
+ else
+ setenv LD_LIBRARY_PATH "${dir1}:${dir2}:${dir3}"
+ endif
+ setenv FGETS_COMMAND_FILE "${dir2}/foo.commands"
+ setenv FGETS_PROMPT "foo> "
+ exec "foo" $*

+2004-11-04 Per Bothner <per@bothner.com>
+
+	* pty.c: Import from screen-4.0.2.
+	* configure.in, Makefile.in, config.h.in: Set up autoconf handling,
+	copying a bunk of stuff over from screen.
+	* rlfe.c: Use OpenPTY from pty.c instead of get_master_pty.
+
+2004-11-03 Per Bothner <per@bothner.com>
+
+	* rlfe.c: Get input emphasis (boldening) more robust.
+
+	* rlfe.c: Various cleanups on comments and names.
+
+2003-11-07 Wolfgang Taeuber <wolfgang_taeuber@agilent.com>
+
+	* Specify a history file and the size of the history file with command
+	* line options; use EDITOR/VISUAL to set vi/emacs preference.
+
+1999-09-03 Chet Ramey <chet@nike.ins.cwru.edu>
+
+	* fep.c: Memmove is not universally available. This patch assumes
+ 	that an autoconf test has been performed, and that memcpy is
+ 	available without checking.
+
+	* fep.c: VDISCARD is not universally available, even when termios is.
+
+	* fep.c: If a system doesn't have TIOCSCTTY, the first `open'
+ 	performed after setsid allocates a controlling terminal. The
+ 	original code would leave the child process running on the slave pty
+ 	without a controlling tty if TIOCSCTTY was not available.
+
+	* fep.c: Most versions of SVR4, including solaris, don't allow
+	terminal ioctl calls on the master side of the pty.
+
+1999-08-28 Per Bothner <per@bothner.com>

+rlfe (ReadLine Front-End) is a "universal wrapper" around readline.
+You specify an interactive program to run (typically a shell), and
+readline is used to edit input lines.
+
+There are other such front-ends; what distinguishes this one is that
+it monitors the state of the inferior pty, and if the inferior program
+switches its terminal to raw mode, then rlfe passes your characters
+through directly. This basically means you can run your entire
+session (including bash and terminal-mode emacs) under rlfe.
+
+FEATURES
+
+* Can use all readline commands (and history) in commands that
+read input lines in "canonical mode" - even 'cat'!
+
+* Automatically switches between "readline-editing mode" and "raw mode"
+depending on the terminal mode. If the inferior program invokes
+readline itself, it will do its own line editing. (The inferior
+readline will not know about rlfe, and it will have its own history.)
+You can even run programs like 'emavs -nw' and 'vi' under rlfe.
+The goal is you could leave rlfe always on without even knowing
+about it. (We're not quite there, but it works tolerably well.)
+
+* The input line (after any prompt) is changed to bold-face.
+
+INSTALL
+
+The usual: ./configure && make && make install
+
+Note so far rlfe has only been tested on GNU Linux (Fedora Core 2)
+and Mac OS X (10.3).
+
+This assumes readline header files and libraries are in the default
+places. If not, you can create a link named readline pointing to the
+readline sources. To link with libreadline.a and libhistory.a
+you can copy or link them, or add LDFLAGS='-/path/to/readline' to
+the make command-line.
+
+USAGE
+
+Just run it. That by default runs bash. You can run some other
+command by giving it as command-line arguments.
+
+There are a few tweaks: -h allows you to name the history file,
+and -s allows you to specify its size. It default to "emacs" mode,
+but if the the environment variable EDITOR is set to "vi" that
+mode is chosen.
+
+ISSUES
+
+* The mode switching depends on the terminal mode set by the inferior
+program. Thus ssh/telnet/screen-type programs will typically be in
+raw mode, so rlfe won't be much use, even if remote programs run in
+canonical mode. The work-around is to run rlfe on the remote end.
+
+* Echo supression and prompt recognition are somewhat fragile.
+(A protocol so that the o/s tty code can reliably communicate its
+state to rlfe could solve this problem, and the previous one.)
+
+* See the intro to rlfe.c for more notes.
+
+* Assumes a VT100-compatible terminal, though that could be generalized
+if anybody cares.
+
+* Requires ncurses.
+
+* It would be useful to integrate rlfe's logic in a terminal emulator.
+That would make it easier to reposition the edit position with a mouse,
+integrate cut-and-paste with the system clipboard, and more robustly
+handle escape sequence and multi-byte characters more robustly.

+\`configure' configures this package to adapt to many kinds of systems.
+
+Usage: $0 OPTION... VAR=VALUE...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE disabled
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR configure dir or \`..'
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ $ac_default_prefix
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ PREFIX
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables EPREFIX/bin
+ --sbindir=DIR system admin executables EPREFIX/sbin
+ --libexecdir=DIR program executables EPREFIX/libexec
+ --sysconfdir=DIR read-only single-machine data PREFIX/etc

+/* PROBLEMS/TODO:
+ *
+ * Only tested under GNU/Linux and Mac OS 10.x; needs to be ported.
+ *
+ * Switching between line-editing-mode vs raw-char-mode depending on
+ * what tcgetattr returns is inherently not robust, plus it doesn't
+ * work when ssh/telnetting in. A better solution is possible if the
+ * tty system can send in-line escape sequences indicating the current
+ * mode, echo'd input, etc. That would also allow a user preference
+ * to set different colors for prompt, input, stdout, and stderr.
+ *
+ * When running mc -c under the Linux console, mc does not recognize
+ * mouse clicks, which mc does when not running under rlfe.
+ *
+ * Pasting selected text containing tabs is like hitting the tab character,
+ * which invokes readline completion. We don't want this. I don't know
+ * if this is fixable without integrating rlfe into a terminal emulator.
+ *
+ * Echo suppression is a kludge, but can only be avoided with better kernel
+ * support: We need a tty mode to disable "real" echoing, while still
+ * letting the inferior think its tty driver to doing echoing.
+ * Stevens's book claims SCR$ and BSD4.3+ have TIOCREMOTE.
+ *
+ * The latest readline may have some hooks we can use to avoid having
+ * to back up the prompt. (See HAVE_ALREADY_PROMPTED.)
+ *
+ * Desirable readline feature: When in cooked no-echo mode (e.g. password),
+ * echo characters are they are types with '*', but remove them when done.
+ *
+ * Asynchronous output while we're editing an input line should be
+ * inserted in the output view *before* the input line, so that the
+ * lines being edited (with the prompt) float at the end of the input.
+ *
+ * A "page mode" option to emulate more/less behavior: At each page of
+ * output, pause for a user command. This required parsing the output
+ * to keep track of line lengths. It also requires remembering the
+ * output, if we want an option to scroll back, which suggests that
+ * this should be integrated with a terminal emulator like xterm.

+ * This is an implementation of wcwidth() and wcswidth() (defined in
+ * IEEE Std 1002.1-2001) for Unicode.
+ *
+ * http://www.opengroup.org/onlinepubs/007904975/functions/wcwidth.html
+ * http://www.opengroup.org/onlinepubs/007904975/functions/wcswidth.html
+ *
+ * In fixed-width output devices, Latin characters all occupy a single
+ * "cell" position of equal width, whereas ideographic CJK characters
+ * occupy two such cells. Interoperability between terminal-line
+ * applications and (teletype-style) character terminals using the
+ * UTF-8 encoding requires agreement on which character should advance
+ * the cursor by how many cell positions. No established formal
+ * standards exist at present on which Unicode character shall occupy
+ * how many cell positions on character terminals. These routines are
+ * a first attempt of defining such behavior based on simple rules
+ * applied to data provided by the Unicode Consortium.
+ *
+ * For some graphical characters, the Unicode standard explicitly
+ * defines a character-cell width via the definition of the East Asian
+ * FullWidth (F), Wide (W), Half-width (H), and Narrow (Na) classes.
+ * In all these cases, there is no ambiguity about which width a
+ * terminal shall use. For characters in the East Asian Ambiguous (A)
+ * class, the width choice depends purely on a preference of backward
+ * compatibility with either historic CJK or Western practice.
+ * Choosing single-width for these characters is easy to justify as
+ * the appropriate long-term solution, as the CJK practice of
+ * displaying these characters as double-width comes from historic
+ * implementation simplicity (8-bit encoded characters were displayed
+ * single-width and 16-bit ones double-width, even for Greek,
+ * Cyrillic, etc.) and not any typographic considerations.
+ *
+ * Much less clear is the choice of width for the Not East Asian
+ * (Neutral) class. Existing practice does not dictate a width for any
+ * of these characters. It would nevertheless make sense
+ * typographically to allocate two character cells to characters such
+ * as for instance EM SPACE or VOLUME INTEGRAL, which cannot be
+ * represented adequately with a single-width glyph. The following
+ * routines at present merely assign a single-cell width to all
+ * neutral characters, in the interest of simplicity. This is not
+ * entirely satisfactory and should be reconsidered before
+ * establishing a formal standard in this area. At the moment, the
+ * decision which Not East Asian (Neutral) characters should be
+ * represented by double-width glyphs cannot yet be answered by
+ * applying a simple rule from the Unicode database content. Setting
+ * up a proper standard for the behavior of UTF-8 character terminals
+ * will require a careful analysis not only of each Unicode character,
+ * but also of each presentation form, something the author of these
+ * routines has avoided to do so far.
