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.

BUGS¶
Please report any bugs or feature requests on the bugtracker website <https://rt.cpan.org/Public/Dist/Display.html?Name=Function-Fallback-CoreOrPP>
When submitting a bug or request, please include a test-file or a patch to an existing test-file that illustrates the bug or desired feature.
SEE ALSO¶
Clone::Any can also use multiple backends. I used to avoid it because Storable's "dclone" (which is used as the backend) did not support Regexp objects out of the box until version 3.08. Plus must use deparse to handle coderefs.
