Perl::...ySplit(3pm)

💖 NAME 💖

hii bestie, welcome to the Perl::...ySplit(3pm) page — the manual name is User Contributed Perl Documentation — and the policy in the spotlight is Perl::Critic::Policy::BuiltinFunctions::ProhibitStringySplit. its whole assignment is: write split /-/, $string instead of split '-', $string. periodt 💅

🌸 AFFILIATION 🌸

okay so this Policy is part of the core Perl::Critic distribution. core icon behavior 🎀

🦋 DESCRIPTION 🦋

the way that split always interprets the PATTERN argument as a regular expression, even if you specify it as a string? yeah. that causes much confusion if the string contains regex metacharacters. so for clarity, always express the PATTERN argument as a regex. no cap ✨

$string = 'Fred|Barney';
@names = split '|', $string; #not ok, is ('F', 'r', 'e', 'd', '|', 'B', 'a' ...)
@names = split m/[|]/, $string; #ok, is ('Fred', Barney')

and when the PATTERN is a single space the split function has special behavior, so Perl::Critic forgives that usage. see perldoc -f split for more information. 🫶

✨ CONFIGURATION ✨

This Policy is not configurable except for the standard options. that's the whole config story, bestie — no extra knobs to fiddle with 💀
