YAML::Any - Pick a YAML implementation and use it.


WARNING: This module will soon be deprecated. The plan is that itself will act like an Any module.


    use YAML::Any;
    $YAML::Indent = 3;
    my $yaml = Dump(@objects);


There are several YAML implementations that support the Dump/Load API. This module selects the best one available and uses it.


Currently, YAML::Any will choose the first one of these YAML implementations that is installed on your system:

  • YAML::XS

  • YAML::Syck

  • YAML::Old

  • YAML

  • YAML::Tiny


If you specify an option like:

    $YAML::Indent = 4;

And YAML::Any is using YAML::XS, it will use the proper variable: $YAML::XS::Indent.


Like all the YAML modules that YAML::Any uses, the following subroutines are exported by default:

  • Dump

  • Load

and the following subroutines are exportable by request:

  • DumpFile

  • LoadFile


YAML::Any provides the following class methods.


This method returns a list of the current possible implementations that YAML::Any will search for.


This method returns the implementation the YAML::Any will use. This result is obtained by finding the first member of YAML::Any->order that is either already loaded in %INC or that can be loaded using require. If no implementation is found, an error will be thrown.


DumpFile and LoadFile

Here is an example for DumpFile:


    use strict;
    use warnings;

    use YAML::Any qw(DumpFile);

    my $ds =
        array => [5,6,100],
        string => "Hello",

    DumpFile("hello.yml", $ds);

When run, this creates a file called hello.yml in the current working directory, with the following contents.

    - 5
    - 6
    - 100
    string: Hello

In turn, the following LoadFile example, loads the contents from there and accesses them:


    use strict;
    use warnings;

    use YAML::Any qw(LoadFile);

    my ($ds) = LoadFile("hello.yml");

    print "String == '", $ds->{string}, "'\n";

Assuming hello.yml exists, and is as created by the DumpFile example, it prints:

    $ perl
    String == 'Hello'
