[![Build Status](https://travis-ci.org/moznion/Regexp-Lexer.svg?branch=master)](https://travis-ci.org/moznion/Regexp-Lexer) # NAME Regexp::Lexer - Lexer for regular expression of perl # SYNOPSIS use Regexp::Lexer qw(tokenize); my $tokens = tokenize(qr{\Ahello\s+world\z}i); # DESCRIPTION Regexp::Lexer is a lexer for regular expression of perl. This module splits the regular expression string to tokens which has minimum meaning. # FUNCTIONS - `tokenize($re:Regexp)` Tokenizes the regular expression. This function takes an argument as `Regexp`, namely it must be regexp quoted variable (i.e. `qr/SOMETHING/`). If not `Regexp` argument is given, this function throws exception. This function returns the result like so; { tokens => [ { char => '\A', index => 1, type => { id => 67, name => 'EscapedBeginningOfString', }, }, { char => 'h', index => 2, type => { id => 1, name => 'Character', }, }, ... ], modifiers => ['^', 'i'], } `tokens` is the tokens list. Information about `type` of token is located in the [Regexp::Lexer::TokenType](https://metacpan.org/pod/Regexp::Lexer::TokenType). `modifiers` is the list of modifiers of regular expression.
