perl::critic::policy::controlstructures::prohibitdeepnests

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
