in reply to Listing dependencies for Perl modules--should even the common ones get listed?

G'day Polyglot,

My thinking on this has varied over time: no core modules; no core pragmata; all modules.

My current thinking is:

I concur with what ++hippo pointed out: "Just because they are in core today ...". For example: 

$ corelist CGI

Data for 2023-09-20
CGI was first released with perl 5.004, deprecated (will be CPAN-only)
+ in v5.19.7 and removed from v5.21.0

And, of course, my thinking on this may change yet again at some future time. So, consider this as only suggestions and guidelines; then make your own choices.

    I list author-only stuff under `develop.requires`. A snippet from GraphQL's Makefile.PL: 
    WriteMakefile(
  NAME             => 'GraphQL',
# ...
  META_MERGE => {
    "meta-spec" => { version => 2 },
    dynamic_config => 0,
    resources => {
      x_IRC => 'irc://irc.perl.org/#graphql-perl',
      repository => {
        type => 'git',
        url => 'git@github.com:graphql-perl/graphql-perl.git',
        web => 'https://github.com/graphql-perl/graphql-perl',
      },
      bugtracker  => {
        web => 'https://github.com/graphql-perl/graphql-perl/issues',
      },
      license => [ 'http://dev.perl.org/licenses/' ],
    },
    prereqs => {
      develop => {
        requires => {
          'Test::Pod::Coverage' => '1.08',
          'Test::Pod' => '1.22',
          'Pod::Markdown' => 0,
        },
      },
      runtime => {
        suggests => {
          'Cpanel::JSON::XS' => '3.0237',
          'JSON::XS' => 0,
        },
      },
    },
  },
);

    That lets me minimise or avoid specifying them separately in continuous integration (CI) config.

      G'day etj,

      That's a far more complicated Makefile.PL than I currently write; however, I can see some distinct benefits to using it.

      I found ExtUtils::MakeMaker - META_MERGE which has some limited information. It doesn't mention {prereqs}{develop}{requires} or {prereqs}{runtime}{suggests}; I suspect there may be others.

      Can you point me to a definitive reference for the META_MERGE key? Thankyou.

      — Ken
