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
DESCRIPTIONModule::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.
