Finally, META.yml customization in MakeMaker

brian_d_foy on 2008-09-06T15:58:00

In a fit of wild yak shaving, I finally adapted Adriano Ferreira's patch to allow customization of the META.yml file in MakeMaker so I can add "resources" to Test::More. Now you can pass in data structures via META_ADD or META_MERGE to, respectively, add/override or merge META.yml values.

For example, MakeMaker itself does this.

    META_MERGE      => {
        no_index => {
            package => ['DynaLoader'],
        },
        resources => {
            license     =>      'http://dev.perl.org/licenses/',
            homepage    =>      'http://makemaker.org',
            bugtracker  =>      'http://rt.cpan.org/NoAuthBugs.html?Dist=ExtUtils-MakeMaker',
            repository  =>      'http://svn.schwern.org/svn/CPAN/ExtUtils-MakeMaker',
            'MailingList' =>    'makemaker@perl.org',
        },
    },

I also brought the default META.yml up to the 1.4 spec, added in a default no_index for t/ and inc/ and a configure_requires on MakeMaker itself filling in long unspoken assumptions.

Here's what MakeMaker's META.yml looks like now:

--- #YAML:1.0

Awesome!
