NAME

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

CONTENTS

AFFILIATION

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

DESCRIPTION

Deeply nested code is often hard to understand and may be a sign that it needs to be refactored. There are several good books on how to refactor code. I like Martin Fowler’s Refactoring: Improving The Design of Existing Code.

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
