Perl::Critic::Policy::TestingAnUsPerl::Critic::Policy::TestingAndDebugging::RequireUseWarnings(3)

NAME
       Perl::Critic::Policy::TestingAndDebugging::RequireUseWarnings - Always "use warnings".

AFFILIATION
       This Policy is part of the core Perl::Critic distribution.

DESCRIPTION
       Using warnings, and paying attention to what they say, is probably the single most
       effective way to improve the quality of your code.  This policy requires that the 'use
       warnings' statement must come before any other statements except "package", "require", and
       other "use" statements.	Thus, all the code in the entire package will be affected.

       There are special exemptions for Moose, Moose::Role, and Moose::Util::TypeConstraints
       because they enforces warnings; e.g.  'use Moose' is treated as equivalent to 'use
       warnings'.

       This policy will not complain if the file explicitly states that it is compatible with a
       version of perl prior to 5.6 via an include statement, e.g. by having "require 5.005" in
       it.

       The maximum number of violations per document for this policy defaults to 1.

CONFIGURATION
       If you take make use of things like Moose::Exporter, you can create your own modules that
       import the warnings pragma into the code that is "use"ing them.	There is an option to add
       to the default set of pragmata and modules in your .perlcriticrc: "equivalent_modules".

	   [TestingAndDebugging::RequireUseWarnings]
	   equivalent_modules = MooseX::My::Sugar

BUGS
       Needs to check for -w on the shebang line.
