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.
