YAML::XS(3) Perl YAML Serialization using XS and libyaml


use YAML::XS;
my $yaml = Dump [ 1..4 ];
my $array = Load $yaml;


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.


If enabled supports deparsing and evaling of code blocks.
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.


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.
