NAME

Function::Fallback::CoreOrPP - Functions that use non-core XS module but provide pure-Perl/core fallback

VERSION

This document describes version 0.090 of Function::Fallback::CoreOrPP (from Perl distribution Function-Fallback-CoreOrPP), released on 2020-02-03.

SYNOPSIS

 use Function::Fallback::CoreOrPP qw(clone unbless uniq);

 my $clone = clone({blah=>1});
 my $unblessed = unbless($blessed_ref);
 my @uniq  = uniq(1, 3, 2, 1, 4);  # -> (1, 3, 2, 4)

DESCRIPTION

This module provides functions that use non-core XS modules (for best speed, reliability, feature, etc) but falls back to those that use core XS or pure-Perl modules when the non-core XS module is not available.

This module helps when you want to bootstrap your Perl application with a portable, dependency-free Perl script. In a vanilla Perl installation (having only core modules), you can use App::FatPacker to include non-core pure-Perl dependencies to your script.

FUNCTIONS

clone($data) => $cloned

Try to use Data::Clone's "clone", but fall back to using Clone::PP's "clone".

clone_list(@data) => @data

A shortcut for:

 return map {clone($_)} @data

unbless($ref) => $unblessed_ref

Try to use Acme::Damn's "damn" to unbless a reference but fall back to shallow copying.

NOTE: "damn()" MODIFIES the original reference. (XXX in the future an option to clone the reference first will be provided), while shallow copying will return a shallow copy.

NOTE: The shallow copy method currently only handles blessed {scalar,array,hash}ref as those are the most common.

uniq(@ary) => @uniq_ary

Try to use List::MoreUtils's "uniq", but fall back to using slower, pure-Perl implementation.
