💖 NAME 💖

Okay bestie, this page is MakeMe...ty::Ref(3pm) from the User Contributed Perl Documentation, and the full glow-up is:

Class::MakeMethods::Utility::Ref — deep copying and comparison. It's giving utility-module excellence, no cap. ✨

🌸 SYNOPSIS 🌸

use Class::MakeMethods::Utility::Ref qw( ref_clone ref_compare );

$deep_copy = ref_clone( $original );
$positive_zero_or_negative = ref_compare( $item_a, $item_b );

🦋 DESCRIPTION 🦋

This module hands you utility functions to copy and compare arbitrary references, including full traversal of nested data structures. Like, it really goes in. 💅

🎀 REFERENCE 🎀

The following functions are provided, bestie:

ref_clone() 🫶

Make a recursive copy of a reference.

ref_compare() ⭐

Attempt to recursively compare two references.

If they are not the same, it tries to be consistent about returning a positive or negative number so it can be used for sorting. The sort order is kinda arbitrary — lowkey iconic, highkey chaotic. 😭

💜 SEE ALSO 💜

  • See Class::MakeMethods for general information about this distribution.
  • See Ref for the original version of the clone and compare functions used above.
  • See Clone (v0.09 on CPAN as of 2000-09-21) for a clone method with an XS implementation.
  • The Perl6 RFP #67 proposes including clone functionality in the core.
  • See Data::Compare (v0.01 on CPAN as of 1999-04-24) for a Compare method which checks two references for similarity, but it does not provide positive/negative values for ordering purposes.

And that's the whole page, bestie — cute little sign-off with the source/version/date vibes: perl v5.36.0, dated 2022-10-13. Slay. 💖🎀✨
