NAME
    YAML::Perl - Pure Perl YAML Implementation

WARNING
    This is an early release of PyYaml ported to Perl. Don't even bother to
    try this version.

    Still here?

    This port is nearing completion. Most stuff works including:

        * Loading and dumping of basic types
        * Block and flow styles (JSON Loading)
        * Blessed hashes arrays and scalars
        * References
        * Tags
        * Detailed error messages
        * Lot's of new stuff like parser/emitter streaming api

    You can play with it by using:

        ysh -MYAML::Perl

TODO
        * Review all code ported so far
        * Port diff from old copy of pyyaml to current version
        * Do all the utf8 related code porting that I've ignored
        * Port the pyyaml test suite to Perl
          * Get all tests to pass
        * Support esoteric Perl types like regexps and globs
        * Support the PyYAML tag resolution API
        * Write full documentation for YAML::Perl
        * Support YAML::Node from YAML::Perl

SYNOPSIS
        use YAML::Perl;

        my $data = {
            name => 'Ingy döt Net',
            modules => [
                'YAML', 'YAML::Old', 'YAML::Perl', YAML::XS'
            ],
        };

        my $yaml = <<'...';
        ---
        modules:
        - YAML
        - YAML::Old
        - YAML::Perl
        - YAML::XS
        name: Ingy döt Net
        ...

        # Simple, familiar, Dump/Load API
        my $yaml2 = Dump $data;
        my $data2 = Load $yaml;

        # New, non-global dump API:
        my $yaml3 = YAML::Perl->new->dumper(%options)->dump($data);

        # New load API
        my $data3 = YAML::Perl->new->loader(%options)->open($yaml)->load();

        # New Streaming Parser/Emitter API
        my $yaml4;
        my $parser = YAML::Perl->new->parser->open($yaml);
        my $emitter = YAML::Perl->new-emitter->open($yaml4);
        while (my $event = $parser->parse()) {
            # Do various things with events here
            $emitter->emit($event);
        }
        $emitter->close;
        print $yaml4;

DESCRIPTION
    PyYAML is the most robust and correct YAML module for a dynamic
    language. It is (obviously) written in/for Python. This module is a
    complete port of PyYAML to Perl.

STREAMING API
    YAML::Parser reads a YAML serialization stream and produces events.
    YAML::Emitter takes YAML events and produces a YAML serialization
    stream.

    Both of these modules allow you to process all the yaml/events at once,
    or do things one event at a time. If you call the YAML::Parser "parse()"
    method in list context, you get all the remaining event objects. If you
    call it in scalar context, you get the next event.

    The YAML::Emitter "emit()" method takes one or more event objects as
    input arguments.
