Perl::...IfElse(3pm)

💅 NAME 💅

okay so this is the Perl::...IfElse(3pm) page from User Contributed Perl Documentation, and it's giving Perl::Critic policy realness. The actual policy name is Perl::Critic::Policy::ControlStructures::ProhibitCascadingIfElse, and its whole vibe is: don't write long if-elsif-elsif-elsif-elsif...else chains. Periodt. 🫶

🦋 AFFILIATION 🦋

This Policy is part of the core Perl::Critic distribution. It's already in the core lineup, bestie. ✨

🌸 DESCRIPTION 🌸

Long if-elsif chains are hard to digest, especially if they are longer than a single page or screen. If testing for equality, use a hash lookup instead. Lowkey iconic advice. 💖

here's the visual so you can vibe check it:

if ($condition1) {         #ok
    $foo = 1;
}
elsif ($condition2) {      #ok
    $foo = 2;
}
elsif ($condition3) {      #ok
    $foo = 3;
}
elsif ($condition4) {      #too many!
    $foo = 4;
}
else {                     #ok
    $foo = $default;
}

🎀 CONFIGURATION 🎀

This policy can be configured with a maximum number of elsif alternatives to allow. The default is 2. You can set it with a max_elsif item in the .perlcriticrc file, like this:

[ControlStructures::ProhibitCascadingIfElse]
max_elsif = 3

That's the config moment, bestie. 🦋
