List all used modules in META.yml requires


  • Exporter
  • strict
  • vars


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

Error: 0.06,1.06,1.17,1.28


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.


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: Math::String, Math::String::Charset, Math::String::Charset::Grouped, Math::String::Charset::Nested, Math::String::Sequence


List all modules used in the test suite in META.yml build_requires


  • Test
  • strict


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).


Name Abstract Version View
Math::String Arbitrary sized integers having arbitrary charsets to calculate with key rooms 1.28 metacpan
Math::String::Charset A simple charset for Math::String objects. 1.17 metacpan
Math::String::Charset::Grouped A charset of simple charsets for Math::String objects. 0.06 metacpan
Math::String::Charset::Nested A charset for Math::String objects. 0.06 metacpan
Math::String::Sequence defines a sequence (range) of Math::String(s) 1.06 metacpan
