• -d — 🔍 Finds the first perl version where a module has been released by date, and not by version number (as is the default).

🔄 --diff

Given two versions of perl, this prints a human-readable table of all module changes between the two. The output format may change in the future, and is meant for humans, not programs. For programs, use the Module::CoreList API.

• -? or -help — ❓ help! help! help! to see more help, try --man.
• -man — 📖 all of the help

🔢 -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 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.

🛠️ --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.

🎯 --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.

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)

$ corelist File::Spec::Aliens

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

$ corelist /IPC::Open/

IPC::Open2 was first released with perl 5

IPC::Open3 was first released with perl 5

$ corelist /MANIFEST/i

ExtUtils::Manifest was first released with perl 5.001

$ corelist /Template/

/Template/  has no match in CORE (or so I think)

$ corelist -v 5.8.8 B

B                        1.09_01
