Perl::Critic::Perl::Critic::Policy::TestingAndDebugging::RequireUseWarnings(3)NAMEPerl::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.
