corelist - a commandline frontend to Module::CoreList


See Module::CoreList for one.


corelist -v
corelist [-a|-d] <ModuleName> | /<ModuleRegex>/ [<ModuleVersion>] ...
corelist [-v <PerlVersion>] [ <ModuleName> | /<ModuleRegex>/ ] ...
corelist [-r <PerlVersion>] ...
corelist --diff PerlVersion PerlVersion



lists all versions of the given module (or the matching modules, in case you used a module regexp) in the perls Module::CoreList knows about.

finds the first perl version where a module has been released by date, and not by version number (as is the default).


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.

all of the help


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.


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.

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.
