Alien::Util(3)

✨ NAME ✨

okay bestie, meet Alien::Util - Alien Utilities used at build and runtime. This is the Alien::Util(3) page, hanging out in User Contributed Perl Documentation, and it's giving small but crucial helper module energy. 💖

🦋 VERSION 🦋

version 2.88 — slay, that's the one. ✨

💅 SYNOPSIS 💅

okay so the whole import vibe is literally:

use Alien::Util qw( version_cmp );

🌸 DESCRIPTION 🌸

This module contains some functions used by both the Alien::Build build-time and <Alien::Base> run-time for Alien. Lowkey iconic, highkey useful. 🫶

🎀 version_cmp 🎀

$cmp = version_cmp($x, $y)

This is the comparison method used by "atleast_version" in Alien::Base, "exact_version" in Alien::Base, and "max_version" in Alien::Base. It may be useful to implement custom comparisons, or for subclasses to overload to get different version comparison semantics than the default rules — for packages that have some other rules than the pkg-config behaviour. No cap. 🧚

It should return a number less than, equal to, or greater than zero; similar in behaviour to the <=> and cmp operators.
