SYNOPSIS use Module::CoreList::More; # true, this module has always been in core since specified perl release Module::CoreList::More->is_still_core("Benchmark", 5.010001); # false, since CGI is removed in perl 5.021000 Module::CoreList::More->is_still_core("CGI"); # false, never been in core Module::CoreList::More->is_still_core("Foo"); my %modules = list_still_core_modules(5.010001); DESCRIPTION This module is my experiment for providing more functionality to (or related to) Module::CoreList. Some ideas include: faster functions, more querying functions, more convenience functions. When I've got something stable and useful to show for, I'll most probably suggest the appropriate additions to Module::CoreList. Below are random notes: FUNCTIONS These functions are not exported. They can be called as function (e.g. Module::CoreList::More::is_still_core($name) or as class method (e.g. Module::CoreList::More->is_still_core($name). first_release( MODULE ) Like Module::CoreList's version, but faster (see "BENCHMARK"). first_release_by_date( MODULE ) Like Module::CoreList's version, but faster (see "BENCHMARK"). removed_from( MODULE ) Like Module::CoreList's version, but faster (see "BENCHMARK"). removed_from_by_date( MODULE ) Like Module::CoreList's version, but faster (see "BENCHMARK"). is_core( MODULE, [ MODULE_VERSION, [ PERL_VERSION ] ] ) Like Module::CoreList's version, but faster (see "BENCHMARK"). is_still_core( MODULE, [ MODULE_VERSION, [ PERL_VERSION ] ] ) Like is_core, but will also check that from PERL_VERSION up to the latest known version, MODULE has never been removed from core. Note/idea: could also be implemented by adding a fourth argument MAX_PERL_VERSION to is_core, defaulting to the latest known version. list_core_modules([ PERL_VERSION ]) => %modules List modules that are in core at specified perl release. list_still_core_modules([ PERL_VERSION ]) => %modules List modules that are (still) in core from specified perl release to the latest. Keys are module names, while values are versions of said modules in specified perl release. BENCHMARK #COMMAND: devscripts/bench SEE ALSO Module::CoreList
