Test::CPAN::Meta(3)

NAME
Test::CPAN::Meta - Validate your CPAN META.yml files.

SYNOPSIS
There are two forms this module can be used.

The first is a standalone test of your distribution's META.yml file:

  use Test::More;
  eval "use Test::CPAN::Meta";
  plan skip_all => "Test::CPAN::Meta required for testing META.yml" if $@;
  meta_yaml_ok();

Note that you may provide an optional label/comment/message/etc to the function, or one will be created automatically.

The second form allows you to test other META.yml files, or specify a specific version you wish to test against:

  use Test::More tests => 6;
  use Test::CPAN::Meta;

  # specify a file and specification version
  meta_spec_ok('META.yml','1.3',$msg);

  # specify the specification version to validate the local META.yml
  meta_spec_ok(undef,'1.3',$msg);

  # specify a file, where the specification version is deduced
  # from the file itself
  meta_spec_ok('META.yml',undef,$msg);

Note that this form requires you to specify the number of tests you will be running in your test script. Also note that each 'meta_spec_ok' is actually 2 tests under the hood.

DESCRIPTION
This distribution was written to ensure that a META.yml file, provided with a standard distribution uploaded to CPAN, meets the specifications that are slowly being introduced to module uploads, via the use of package makers and installers such as ExtUtils::MakeMaker, Module::Build and Module::Install.

See CPAN::Meta for further details of the CPAN Meta Specification.

FUNCTIONS

•   meta_yaml_ok([$msg])

    Basic META.yml wrapper around meta_spec_ok.

    Returns a hash reference to the contents of the parsed META.yml

•   meta_spec_ok($file, $version [,$msg])

    Validates the named file against the given specification version. Both $file and $version can be undefined.

    Returns a hash reference to the contents of the given file, after it has been parsed.

TESTING META FILES
There are currently 3 distributions to test META files:

  Test-CPAN-Meta
  Test-CPAN-Meta-JSON
  Test-CPAN-Meta-YAML

All three have slightly different requirements and are intended to be used in slightly different environments.

Test-CPAN-Meta-YAML requires a YAML parser, and currently looks for the YAML or YAML::Syck modules. This is the original variant of the 3 and was intended to provide a more complete YAML validation of a META.yml.

Test-CPAN-Meta requires the Parse::CPAN::Meta module, which is now part of Perl Core as of perl-5.10.1. This version is intended to be used by those only wishing to rely on core modules to test their META.yml files.

Test-CPAN-Meta-JSON is the most recent addition to the family, and is specifically aimed at those distributions that use a META.json Meta file. The distribution requires the JSON module to parse the Meta file.

BUGS, PATCHES & FIXES
There are no known bugs at the time of this release. However, if you spot a bug or are experiencing difficulties that are not explained within the POD documentation, please send an email to barbie@cpan.org or submit a bug to the RT system (http://rt.cpan.org/Public/Dist/Display.html?Name=Test-CPAN-Meta). However, it would help greatly if you are able to pinpoint problems or even supply a patch.

Fixes are dependent upon their severity and my availability. Should a fix not be forthcoming, please feel free to (politely) remind me.
