• Nesting in YAML (Score:1)

  by ferreira (5993)

  The nesting of data structures in YAML blocks is indicated by indenting. So that:

  optional_features:
    - foo:
      description:        test
      requires_os:        Linux
      requires:
        Test::More:       0.47

  is just a tight version of

  optional_features:
    -
      foo:
      description:        test
      requires_os:        Linux

    You were almost there :-)

    Actually, you don't need the '-':

    #!env perl
    
    use strict;
    use strict;
    use warnings;
    
    use Data::Dumper;
    use YAML qw(Load);
    
    my $s = Load(<<EOF);
    ---
    optional_features:
      foo:
        description:        test
        requires_os:        Linux
        requires:
          Test::More:       0.47
      bar:
        description:        test
    
    EOF
    
    print Dumper $s;

    The result is this:

    $VAR1 = {
              'optional_features' => {
                                       'bar' => {
                                                  'description' => 'test'
                                                },
                                       'foo' => {
                                                  'requires_os' => 'Linux',
                                                  'requires' => {
                                                                  'Test::More' => '0.47'
                                                                },
                                                  'description' => 'test'
                                                }
                                     }
            };

      I was interpreting the current META.yml Specification [sourceforge.net] (it's hidden within the Recommends section, as I think the heading has been accidentally omitted). I'd just got the indentation wrong :)
