Kwalitee Issues

No Core Issues.


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.


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

Error: IO::Dir, IO::File, IO::Handle, IO::Pipe, IO::Poll, IO::Seekable, IO::Select, IO::Socket, IO::Socket::INET, IO::Socket::UNIX


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.


  • IO
  • IO::Dir
  • IO::File
  • IO::Handle
  • IO::Pipe
  • IO::Pipe::End
  • IO::Poll
  • IO::Seekable
  • IO::Select
  • IO::Socket
  • IO::Socket::INET
  • IO::Socket::UNIX


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

Error: 0.09,1.10,1.15,1.16,1.22,1.26,1.31,1.35,1.37


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.
