NAME
    Pegex - Acmeist PEG Parser Framework

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 *just*modern 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.
