Manual Reference Pages - PERL::CRITIC::POLICY::CONTROLSTRUCTURES::PROHIBITDEEPNESTS (3)
Perl::Critic::Policy::ControlStructures::ProhibitDeepNests - Dont write deeply nested loops and conditionals.
This Policy is part of the core Perl::Critic
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 Fowlers Refactoring: Improving The
Design of Existing Code.
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:
max_nests = 3
