                                           User Contributed Perl Documentation


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
