💖 CORELIST 💖

okay bestie, gather round, because this is corelist — the command-line frontend to Module::CoreList 🎀 (it lives in the Perl Programmers Reference Guide, iykyk). It's the little gossip girl that knows exactly which module shipped with which perl, and it's about to spill ALL the tea. ✨

🌸 SYNOPSIS 🌸

corelist -v
corelist [-a|-d] <ModuleName> | /<ModuleRegex>/ [<ModuleVersion>] ...
corelist [-v <PerlVersion>] [ <ModuleName> | /<ModuleRegex>/ ] ...
corelist [-r <PerlVersion>] ...
corelist --utils [-d] <UtilityName> [<UtilityName>] ...
corelist --utils -v <PerlVersion>
corelist --feature <FeatureName> [<FeatureName>] ...
corelist --diff PerlVersion PerlVersion
corelist --upstream <ModuleName>

🦋 DESCRIPTION 🦋

See Module::CoreList for one. 💅 (yes that's the whole description, she's mysterious, she's lowkey iconic, we love a minimal queen)

✨ OPTIONS ✨

  • -a — lists all versions of the given module (or the matching modules, if you went the module-regexp route, you sneaky thing) across every perl that Module::CoreList knows about. 👑

  • -d — finds the first perl version where a module was released by date, not by version number (which is what the default does). different sorting energy entirely, fr fr.
  • --diff — you hand her two versions of perl and she prints a human-readable table of every module change between them. 🌈
heads up bestie: the output format may change in the future, and it is meant for humans, not programs. So if you're a program, do NOT parse this — use the Module::CoreList API instead. periodt. 💀
  • -? or -help — help! help! help! to see more help, try --man. (she's a little dramatic about it, honestly relatable 😭)
  • -man — all of the help. the whole thing. the full meal. 🍓
  • -v — lists all of the perl release versions we got the CoreList for. 💜

If you pass a version argument (value of $], like 5.00503 or 5.008008), you get a list of all the modules and their respective versions. (If you have the "version" module, you can also use new-style version numbers, like 5.8.8.)

In module filtering context, it can be used as a Perl version filter.

  • -r — lists all of the perl releases and when they were released 🎀

If you pass a perl version you get the release date for that version only. (birthday lookup but for perl releases, iconic)

  • --utils — lists the first version of perl each named utility program was released with.

May be used with -d to modify the first release criteria.

If used with -v <version> then all utilities released with that version of perl are listed, and any utility programs named on the command line are ignored. (sorry to those utility names, they got ghosted 🙈)

  • --feature, -f — lists the first version bundle of each named feature given. 👑
  • --upstream, -u — Shows if the given module is primarily maintained in perl core or on CPAN and bug tracker URL. (receipts, basically 🧚)

As a special case, if you specify the module name "Unicode", you'll get the version number of the Unicode Character Database bundled with the requested perl versions. ✨

🔥 EXAMPLES 🔥

$ corelist File::Spec

File::Spec was first released with perl 5.005

$ corelist File::Spec 0.83

File::Spec 0.83 was released with perl 5.007003

$ corelist File::Spec 0.89

File::Spec 0.89 was not in CORE (or so I think)
