🌸 Perl::Critic::Policy::ValuesAndExpressions::ProhibitMixedBooleanOperators (3pm) 🌸

okay bestie, welcome to the User Contributed Perl Documentation page for Perl::Critic::Policy::ValuesAndExpressions::ProhibitMixedBooleanOperators — that’s the manual name, and we’re in section 3pm, iykyk. 💅

✨ NAME ✨

This policy is literally here to tell you: Write !$foo && $bar || $baz instead of not $foo && $bar or $baz. That’s the whole assignment. 🎀

🫶 AFFILIATION 🫶

This Policy is part of the core Perl::Critic distribution. iconic, honestly. 💖

🦋 DESCRIPTION 🦋

Conway advises against combining the low-precedence booleans (and or not) with the high-precedence boolean operators (&& || !) in the same expression. Unless you fully understand the differences between the high and low-precedence operators, it is easy to misinterpret expressions that use both. And even if you do understand them, it is not always clear if the author actually intended it. the way that is such a real trap 😭

Here’s the vibe check:

    next if not $foo || $bar;  #not ok
    next if !$foo || $bar;     #ok
    next if !( $foo || $bar ); #ok

slay — see how the ok ones keep it clean? 💅

💜 CONFIGURATION 💜

This Policy is not configurable except for the standard options. So no extra knobs, no secret settings — just the standard options, periodt. 👑
