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.
