Module::CoreList::Utils - phpMan

NAME
    Module::CoreList::Utils - what utilities shipped with versions of perl

SYNOPSIS
     use Module::CoreList::Utils;

     print $Module::CoreList::Utils::utilities{5.009003}{ptar}; # prints 1

     print Module::CoreList::Utils->first_release('corelist');
     # prints 5.008009

     print Module::CoreList::Utils->first_release_by_date('corelist');
     # prints 5.009002

DESCRIPTION
    Module::CoreList::Utils provides information on which core and dual-life
    utilities shipped with each version of perl.

    It provides a number of mechanisms for querying this information.

    There is a functional programming API available for programmers to query
    information.

    Programmers may also query the contained hash structure to find relevant
    information.

FUNCTIONS API
    These are the functions that are available, they may either be called as
    functions or class methods:

      Module::CoreList::Utils::first_release('corelist'); # as a function

      Module::CoreList::Utils->first_release('corelist'); # class method

    "utilities"
        Requires a perl version as an argument, returns a list of utilities
        that shipped with that version of perl, or undef/empty list if that
        perl doesn't exist.

    "first_release( UTILITY )"
        Requires a UTILITY name as an argument, returns the perl version
        when that utility first appeared in core as ordered by perl version
        number or undef ( in scalar context ) or an empty list ( in list
        context ) if that utility is not in core.

    "first_release_by_date( UTILITY )"
        Requires a UTILITY name as an argument, returns the perl version
        when that utility first appeared in core as ordered by release date
        or undef ( in scalar context ) or an empty list ( in list context )
        if that utility is not in core.

    "removed_from( UTILITY )"
        Takes a UTILITY name as an argument, returns the first perl version
        where that utility was removed from core. Returns undef if the given
        utility was never in core or remains in core.

    "removed_from_by_date( UTILITY )"
        Takes a UTILITY name as an argument, returns the first perl version
        by release date where that utility was removed from core. Returns
        undef if the given utility was never in core or remains in core.

DATA STRUCTURES
    These are the hash data structures that are available:

    %Module::CoreList::Utils::utilities
        A hash of hashes that is keyed on perl version as indicated in $].
        The second level hash is utility / defined pairs.
