Regexp::Parser Description

Regexp::Parser is a Perl module for parsing regexes. Regexp::Parser is a Perl module for parsing regexes.This module parses regular expressions (regexes). Its default "grammar" is Perl 5.8.4's regex set. Grammar is quoted because the module does not so much define a grammar as let each matched node state what it expects to match next, but there is not currently a way of extracting a complete grammar. This may change in future versions.This module is designed as a replacement (though not drop-in) for my old YAPE::Regex modules.USAGE:Creating an InstanceTo use this module as is, load it, and create an instance: use Regexp::Parser; my $parser = Regexp::Parser->new;Setting a RegexTo have the parser work on a specific regex, you can do use any of the following methods:$parser = Regexp::Parser->new($regex)You can send the regex to be parsed as the argument to the constructor.$parser->regex($regex)Clears the parser's memory and sets $regex as the regex to be parsed.These two approaches do an initial pass over the regex to make sure it is well-formed -- any warnings or errors will be determined during this initial pass.
