Perl::Critic::Policy::TestingAndDebugging::RequireUseWarUsersContributed Perl DoPerl::Critic::Policy::TestingAndDebugging::RequireUseWarnings(3pm) 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. SEE ALSO

Perl::Critic::Policy::ValuesAndExpressions::RequireInterUsertContrPerl::Critic::Policy::ValuesAndExpressions::RequireInterpolationOfMetachars(3pm) NAME
Perl::Critic::Policy::ValuesAndExpressions::RequireInterpolationOfMetachars - Warns that you might have used single quotes when you really wanted double-quotes. AFFILIATION
This Policy is part of the core Perl::Critic distribution. DESCRIPTION
This policy warns you if you use single-quotes or "q//" with a string that has unescaped metacharacters that may need interpolation. Its hard to know for sure if a string really should be interpolated without looking into the symbol table. This policy just makes an educated guess by looking for metacharacters and sigils which usually indicate that the string should be interpolated. Exceptions o Variable names to "use vars": use vars '$x'; # ok use vars ('$y', '$z'); # ok use vars qw< $a $b >; # ok o Things that look like e-mail addresses: print 'john@foo.com'; # ok $address = 'suzy.bar@baz.net'; # ok CONFIGURATION
The "rcs_keywords" option allows you to stop this policy from complaining about things that look like RCS variables, for example, in deriving values for $VERSION variables. For example, if you've got code like our ($VERSION) = (q<$Revision: 4106 $> =~ m/(d+)/mx); You can specify [ValuesAndExpressions::RequireInterpolationOfMetachars] rcs_keywords = Revision in your .perlcriticrc to provide an exemption. NOTES
Perl's own "warnings" pragma also warns you about this. SEE ALSO
