NAME

YAML::PP::YAMLScript - YAML Load YAMLScript Code as Data

SYNOPSIS

File data.yaml:

    --- !yamlscript
    array =:
      vec: (1 .. 3)
    hash-map: ."foo" array

Run this Perl:

    use YAML::PP::YAMLScript;
    my $ypp = YAML::PP::YAMLScript->new;
    my $data = $ypp->load_file('data.yaml');
    print $ypp->dump_string($data);

Output:

    ---
    foo:
    - 1
    - 2
    - 3

DESCRIPTION

This module lets you use YAML files that are completely programmatic. The YAML files are actually YAMLScript programs that run to produce the desired data.

YAML::PP::YAMLScript is a subclass of YAML::PP that lets you load YAML files written in YAMLScript with the command:

    my $hash = YAML::PP::YAMLScript->new->load_file('foo.yaml');

The file should start with the tag !yamlscript.

When loaded, the YAMLScript program in the file will run and should produce a YAMLScript HashMap value.

The resulting value will be returned as a Perl hashref.
