Perl::...pNests(3pm)

okay bestie, welcome to this User Contributed Perl Documentation page — it’s the 3pm manual for Perl::Critic::Policy::ControlStructures::ProhibitDeepNests (the header labels it Perl::...pNests(3pm)), and it is literally here to tell you: don’t write deeply nested loops and conditionals 💅✨

🎀 NAME 🎀

• Perl::Critic::Policy::ControlStructures::ProhibitDeepNests — Don’t write deeply nested loops and conditionals. periodt.

🌸 AFFILIATION 🌸

This Policy is part of the core Perl::Critic distribution. core fam 🫶

🦋 DESCRIPTION 🦋

Deeply nested code is often hard to understand and may be a sign that it needs to be refactored. no cap, your future self will thank you 😭

There are several good books on how to refactor code. The author says I like Martin Fowler’s "Refactoring: Improving The Design of Existing Code". iconic pick tbh 📚

✨ CONFIGURATION ✨

The maximum number of nested control structures can be configured via a value for max_nests in a .perlcriticrc file.

Each for-loop, if-else, while, and until block is counted as one nest. Postfix forms of these constructs are not counted. The default maximum is 5.

Customization in a .perlcriticrc file looks like this:

[ControlStructures::ProhibitDeepNests]
max_nests = 3

slay, now you can set your own vibe check on nesting depth 💖
