NAME
YAML::XS - Perl YAML Serialization using XS and libyaml

SYNOPSIS
use YAML::XS;

my $yaml = Dump [ 1..4 ];
my $array = Load $yaml;

DESCRIPTION
Kirill Siminov's "libyaml" is arguably the best YAML implementation. The C library is
written precisely to the YAML 1.1 specification. It was originally bound to Python and was
later bound to Ruby.

This module is a Perl XS binding to libyaml which offers Perl the best YAML support to
date.

This module exports the functions "Dump", "Load", "DumpFile" and "LoadFile". These
functions are intended to work exactly like "YAML.pm"'s corresponding functions.

CONFIGURATION
$YAML::XS::UseCode
$YAML::XS::DumpCode
$YAML::XS::LoadCode
If enabled supports deparsing and evaling of code blocks.

$YAML::XS::QuoteNumericStrings
When true (the default) strings that look like numbers but have not been numified will
be quoted when dumping.

This ensures leading that things like leading zeros and other formatting are
preserved.

USING YAML::XS WITH UNICODE
Handling unicode properly in Perl can be a pain. YAML::XS only deals with streams of utf8
octets. Just remember this:

$perl = Load($utf8_octets);
$utf8_octets = Dump($perl);

There are many, many places where things can go wrong with unicode. If you are having
problems, use Devel::Peek on all the possible data points.
