Kwalitee Issues


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


Add =head1 LICENSE and the text of the license to the main module in your code.


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


Add a README to the distribution. It should contain a quick description of your module and how to install it.


Fix the version(s).


Run a proper command ("make manifest" or "./Build manifest", maybe with a force option), or use a distribution builder to generate the MANIFEST. Or update MANIFEST manually.


  • MANIFEST (66) does not match dist (67):
  • Missing in MANIFEST: Makefile.PL


List all used modules in META.yml requires


  • Exception::Class


Add 'use strict' (or its equivalents) to all modules, or convince us that your favorite module is well-known enough and people can easily see the modules are strictly written.

Error: DS::Exception, DS::Exception::Processing, DS::Exception::Processing::Validator


Add =head1 LICENSE and/or the proper text of the well-known license to the main module in your code.


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


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.


Fix the version numbers so that version::is_lax($version) returns true.

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.
