Kwalitee Issues


Add a Changelog (best named 'Changes') to the distribution. It should list at least major changes implemented in newer versions.


Take a look at the META.yml Spec at (for version 1.4) or (for version 2), and change your META.yml accordingly.

Error: Missing mandatory field, 'abstract' (abstract) [Validation: 1.4];value is an undefined string (abstract) [Validation: 1.4]


Remove the offending files/directories!

Error: pm_to_blib


Update MANIFEST.SKIP to exclude MYMETA files. If you are lazy, add "#!install_default" in your MANIFEST.SKIP and update your ExtUtils::Manifest if necessary, then some of the most common files will be excluded.


Remove the POD errors. You can check for POD errors automatically by including Test::Pod to your test suite.

Error: Chart-2.4.10/Chart.pod -- Around line 694: '=item' outside of any '=over'Around line 706: '=item' outside of any '=over'


Add a META.json to the distribution. Your buildtool should be able to autogenerate it.


If you are using Build.PL define the {requires}{perl} = VERSION field. If you are using MakeMaker (Makefile.PL) you should upgrade ExtUtils::MakeMaker to 6.48 and use MIN_PERL_VERSION parameter. Perl::MinimumVersion can help you determine which version of Perl your module needs.


Define the license if you are using in Build.PL. If you are using MakeMaker (Makefile.PL) you should upgrade to ExtUtils::MakeMaker version 6.31.


Move your *.pm files in a directory named 'lib'. The directory structure should look like 'lib/Your/' for a module named 'Your::Module'. If you need to provide additional files, e.g. for testing, that should not be considered for Kwalitee, then you should look at the 'provides' map in META.yml to limit the files scanned; or use the 'no_index' map to exclude parts of the distribution.

Error: Chart/, Chart/, Chart/, Chart/, Chart/, Chart/, Chart/, Chart/, Chart/, Chart/, Chart/, Chart/, Chart/, Chart/, Chart/, Chart/


Add 'use warnings' (or its equivalents) to all modules (this will require perl > 5.6), or convince us that your favorite module is well-known enough and people can easily see the modules warn when something bad happens.

Error: Chart::Bars, Chart::Base, Chart::BrushStyles, Chart::Composite, Chart::Constants, Chart::Direction, Chart::ErrorBars, Chart::HorizontalBars, Chart::Lines, Chart::LinesPoints, Chart::Mountain, Chart::Pareto, Chart::Pie, Chart::Points, Chart::Split, Chart::StackedBars


This is not a critical issue. Currently mainly informative for the CPANTS authors. It might be removed later.


Add all modules contained in this distribution to the META.yml field 'provides'. Module::Build or Dist::Zilla::Plugin::MetaProvides do this automatically for you.


Add a 'repository' resource to the META.yml via 'meta_add' accessor (for Module::Build) or META_ADD parameter (for ExtUtils::MakeMaker).
