Kwalitee Issues


Add a Makefile.PL (for ExtUtils::MakeMaker/Module::Install) or a Build.PL (for Module::Build and its friends), or use a distribution builder such as Dist::Zilla, Dist::Milla, Minilla.


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


Add a MANIFEST to the distribution. Your buildtool should be able to autogenerate it (eg "make manifest" or "./Build manifest")


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


Add tests!


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.

Error: Cannot find MANIFEST in dist.


Fix the version(s).


List all used modules in META.yml requires


  • Tk
  • Tk::Adjuster
  • Tk::Balloon
  • Tk::Derived
  • Tk::Dialog
  • Tk::FileSelect
  • Tk::LabFrame
  • Tk::Listbox
  • Tk::Pretty
  • Tk::ProgressBar
  • Tk::Scale
  • Tk::Tiler


Split the distribution, or fix the version numbers to make them consistent (use the highest version number to avoid version downgrade).

Error: 1,1.0,1.000014,1.06,1.1


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


Add tests or move to the t/ directory!


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.


Ask the owner of the distribution (the one who released it first, or the one who is designated in x_authority) to give you a (co-)maintainer's permission.


  • DBI::Format
  • DBI::Format::Base
  • DBI::Format::Box
  • DBI::Format::Neat
  • DDL::Oracle


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: DBI/, DDL/, Shell/, Shell/, Shell/, Shell/, Shell/, Shell/, Shell/, Shell/, Shell/, Shell/, Shell/, Shell/, Tk/,,,, db/,, db/,,, db/


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: DBI::Format, DDL::Oracle, Shell::Connection, Shell::Current, Shell::Do, Shell::Edit, Shell::File, Shell::Format, Shell::Mark, Shell::Menu, Shell::Meta, Shell::Options, Shell::Properties, Shell::Results, Tk::MonitorBar, orac_Base, orac_FileSelect, orac_Font, orac_Informix, orac_Monitor, orac_Oracle, orac_Print, orac_Shell, orac_Sybase


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