📦
version 5.42.3 · 16 versions

Okay bestie, welcome to the List::Util::XS(3pm) page from the Perl Programmers Reference Guide! 💖 This one is short and sweet, and it’s literally here to tell you whether List::Util was built with a C compiler. Let’s get into it. ✨

✨ NAME ✨

  • List::Util::XS — indicate if List::Util was compiled with a C compiler. 👑

🌸 SYNOPSIS 🌸

use List::Util::XS 1.20;

💖 DESCRIPTION 💖

List::Util::XS can be used as a dependency to ensure List::Util was installed using a C compiler and that the XS version is installed. Slay. 🫶

During installation, $List::Util::XS::VERSION will be set to undef if the XS was not compiled. That’s the vibe check. 😭

Starting with release 1.23_03, Scalar-List-Util is always using the XS implementation, but for backwards compatibility, we still ship the List::Util::XS module which just loads List::Util. Iconic behavior, honestly. 💅

No cap: the module is still shipped for backwards compatibility, and it just loads List::Util. That’s straight from the page. 🫡
