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
