NAME

       Pegex::Regex - Use Pegex Like a Regex

SYNOPSIS

           {
               # Turn on Pegex regular expressions in lexical scope.
               use Pegex::Regex;
               my $grammar = qr{$grammar_text}x;
               $text =~ $grammar;
               my $result = \%/;

               # Turn off Pegex in this scope.
               no Pegex::Regex;
           }

DESCRIPTION

       This is a trivial sugar module that lets you use Pegex parser grammars like regular
       expressions, if you're into that kind of thing.

       This is basically a clone of Damian Conway's Regexp::Grammars module API.  You put a
       grammar into a "qr{...}x" and apply it the input string you want to parse. If the parse is
       successful, you get a data structure of the content in "%/".

       IMHO, building a recursive decscent parser entirely inside of a regular expression, is not
       the clearest way to code. But, of course, TMTOWTDI. :)

NOTE

       This module is just for experimental fun. See Pegex for the right way to use the Pegex
       parsing framework.

TMTOWTDI

       Here's a Pegex::Regex code snippet:

           use Pegex::Regex;
           $text =~ qr{... Pegex grammar text ...};
           $data = \%/;

       And the equivalent Pegex code:

           use Pegex;
           my $data = pegex('... Pegex grammar text ...')->parse($text);

WARNING

       This gateway drug, er, module, technically should not even work.

       It turns your "grammar inside a regexp" into a Pegex::Grammar using qr{} overloading, and
       then turns your regexp itself into a shim that calls the parse method for you. This is
       highly magical and technically makes a reentrant call to the regex engine, which is not
       supported yet. Use at your own risk.

       Better yet, do yourself a favor and learn how to use the Pegex toolset without this
       ::Regex sugar. ":-)"
