While they have great performance --- and are tightly integrated into the Lua interpreter, they are very different --- in syntax and not as powerful as standard regular expressions. So we have --- integrated Perl compatible regular expressions into Lua using PCRE and a --- modified version of the Lua PCRE library written by Reuben Thomas and Shmuel --- Zeigerman. These are the same sort of regular expressions used by Nmap --- version detection. The main modification to their library is that the NSE --- version only supports PCRE expressions instead of both PCRE and POSIX --- patterns. In order to maintain a high script execution speed, the library --- interfacing with PCRE is kept very thin. It is not integrated as seamlessly --- as the Lua string pattern API. This allows script authors to decide when to --- use PCRE expressions versus Lua patterns. The use of PCRE involves a --- separate pattern compilation step, which saves execution time when patterns --- are reused. Compiled patterns can be cached in the NSE registry and reused --- by other scripts. --- --- The documentation for this module is derived from that supplied by the PCRE --- Lua lib. --- --- Warning: PCRE has a history of security vulnerabilities allowing attackers --- who are able to compile arbitrary regular expressions to execute arbitrary --- code. More such vulnerabilities may be discovered in the future. These have --- never affected Nmap because it doesn't give attackers any control over the --- regular expressions it uses. Similarly, NSE scripts should never build --- regular expressions with untrusted network input. Matching hardcoded regular --- expressions against the untrusted input is fine. --- @author Reuben Thomas --- @author Shmuel Zeigerman - -module "pcre" - ---- Returns a compiled regular expression. --- --- The resulting compiled regular expression is ready to be matched against --- strings.

If you want to set the 3rd --- (corresponding to the number 4) and the 1st (corresponding to 1) bit for --- example you would pass the number 5 as a second argument. The compilation --- flags accepted are those of the PCRE C library. These include flags for case --- insensitive matching (<code>1</code>), matching line beginnings --- (<code>^</code>) and endings (<code>$</code>) even in multiline strings --- (i.e. strings containing newlines) (<code>2</code>) and a flag for matching --- across line boundaries (<code>4</code>).
