Perl::Critic::Policy::ControlStructures::ProhibitDeepNesUser)Contributed Perl DocumenPerl::Critic::Policy::ControlStructures::ProhibitDeepNests(3)
NAME
Perl::Critic::Policy::ControlStructures::ProhibitDeepNests - Don't write deeply nested loops and conditionals.
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
