Lua PCRE regular expression functions

PCRE regular expression functions (rex)

The functionality of the PCRE (Perl Compatible Regular Expression) library is available to Lua scripts.

This is exactly the same regular expression matching that is done in triggers and alias matching.

First you create (compile) a regular expression into a rex object using rex.new.

Once the object is compiled you can repeatedly match it against target strings using re:match, re:gmatch, and re:exec (where "re" is the name of the compiled object).

Lua functions

re:exec - Matches a regexp to a string, returning offsets
re:gmatch - Matches a regexp to a string, applying a function
re:match - Matches a regexp to a string
rex.flags - Returns a table of PCRE flags
rex.new - Compiles a regular expression
