NAME

       Pegex - Acmeist PEG Parser Framework

VERSION

       This document describes Pegex version 0.60.  ";

SYNOPSIS

           use Pegex;
           my $result = pegex($grammar)->parse($input);

       or with options:

           use Pegex;
           use ReceiverClass;
           my $parser = pegex($grammar, 'ReceiverClass');
           my $result = $parser->parse($input);

       or more explicitly:

           use Pegex::Parser;
           use Pegex::Grammar;
           my $pegex_grammar = Pegex::Grammar->new(
               text => $grammar,
           );
           my $parser = Pegex::Parser->new(
               grammar => $pegex_grammar,
           );
           my $result = $parser->parse($input);

       or customized explicitly:

           {
               package MyGrammar;
               use Pegex::Base;
               extends 'Pegex::Grammar';
               has text => "your grammar definition text goes here";
               has receiver => "MyReceiver";
           }
           {
               package MyReceiver;
               use base 'Pegex::Receiver';
               got_some_rule { ... }
               got_other_rule { ... }
           }
           use Pegex::Parser;
           my $parser = Pegex::Parser->new(
               grammar => MyGrammar->new,
               receiver => MyReceiver->new,
           );
           $parser->parse($input);
           my $result = $parser->receiver->data;

DESCRIPTION

       Pegex is an Acmeist parser framework. It allows you to easily create parsers that will
       work equivalently in lots of programming languages! The inspiration for Pegex comes from
       the parsing engine upon which the postmodern programming language Perl 6 is based on.
       Pegex brings this beauty to the other justmodern languages that have a normal regular
       expression engine available.

       Pegex gets it name by combining Parsing Expression Grammars (PEG), with Regular Expessions
       (Regex). That's actually what Pegex does.

       PEG is the cool new way to elegantly specify recursive descent grammars. The Perl 6
       language is defined in terms of a self modifying PEG language called Perl 6 Rules. Regexes
       are familiar to programmers of most modern programming languages. Pegex defines a simple
       PEG syntax, where all the terminals are regexes. This means that Pegex can be quite fast
       and powerful.

       Pegex attempts to be the simplest way to define new (or old) Domain Specific Languages
       (DSLs) that need to be used in several programming languages and environments. Things like
       JSON, YAML, Markdown etc. It also great for writing parsers/compilers that only need to
       work in one language.

USAGE

       The "Pegex.pm" module itself (this module) is just a trivial way to use the Pegex
       framework. It is only intended for the simplest of uses.

       This module exports a single function, "pegex", which takes a Pegex grammar string as
       input. You may also pass a receiver class name after the grammar.

           my $parser = pegex($grammar, 'MyReceiver');

       The "pegex" function returns a Pegex::Parser object, on which you would typically call the
       "parse()" method, which (on success) will return a data structure of the parsed data.

       See Pegex::API for more details.
