Listify(3pm)

💅 NAME 💅

Scalar::Listify — bestie, it produces an array (or array ref?? 👀) from a scalar value or an array ref. That's the whole vibe. Periodt.

✨ SYNOPSIS ✨

okay so picture this:

use Scalar::Listify;

$text_scalar = 'text';
$aref_scalar = [ 1.. 5 ];

print join ':', listify $text_scalar; # => text
print join ':', listify $aref_scalar; # => 1:2:3:4:5

like… it just works?? the scalar case gives you text, the arrayref case gives you 1:2:3:4:5. no drama, no chaos, just slay. 🦋

🌸 DESCRIPTION 🌸

so here's the situation that literally every Perl dev has lived through at least once: your code ends up holding a scalar that's either one single scalar value or a reference to an array full of scalar values. and you're just standing there like 🧍 because now you have to figure out which one you're holding before you can actually do the thing you wanted to do. it's giving side quest.

the classic move looks like this:

$text_scalar = 'text';
$aref_scalar = [ 1.. 5 ];

print ref($text_scalar) ? (join ':', @$text_scalar) : $text_scalar;

and this module is designed to address just that! no cap. that's the entire assignment and it ate. 👑

🎀 EXPORT 🎀

• listify() — listify takes a scalar as an argument and hands you back the value of that scalar in a format you can actually use in list contexts. iconic behavior honestly.
• listify_aref() — returns [ listify (@_) ]. cute, right? it's the arrayref glow-up. 💖
