CORELIST(1)

💅 CORELIST(1) 💅

hey bestie, welcome to the corelist page from the Perl Programmers Reference Guide — it’s literally the group chat of every core module’s timeline, and it ate ✨

🌸 NAME 🌸

corelist — a commandline frontend to Module::CoreList

🦋 DESCRIPTION 🦋

bestie, the DESCRIPTION is literally: see Module::CoreList for one. that’s it, that’s the description 💅

✨ 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>

🎀 OPTIONS 🎀

• -a — lists all versions of the given module (or the matching modules, if you used a module regexp) across every perl that Module::CoreList knows about. it’s giving full timeline reveal 🔥

• -d — finds the first perl version where a module was released by date, not by version number. and yes, version-number matching is the default, so this is the plot twist 👀
• --diff — given two versions of perl, this prints a human-readable table of all module changes between the two. for programs, use the Module::CoreList API.

⚠️ heads up bestie: the output format may change in the future, and it’s meant for humans, not programs. no cap.

• -? or -help — help! help! help! to see more help, try --man.
• -man — all of the help. yes, all of it, we love a generous icon 💖
• -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. iykyk 🦋

🌈 EXAMPLES 🌈

okay these are literally the receipts, no cap:

$ 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
