Perl::Critic::Policy::TestingAndDebugging::ProhibitNoWarnings3pm

Affiliation

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

Overview

There are good reasons for disabling certain kinds of warnings. But if you were wise enough to "use warnings" in the first place, then it doesn't make sense to disable them completely. By default, any "no warnings" statement will violate this policy. However, you can configure this Policy to allow certain types of warnings to be disabled (See "CONFIGURATION"). A bare "no warnings" statement will always raise a violation.

Configuration

The permitted warning types can be configured via the "allow" option. The value is a list of whitespace-delimited warning types that you want to be able to disable. See perllexwarn for a list of possible warning types. An example of this customization:

    [TestingAndDebugging::ProhibitNoWarnings]
    allow = uninitialized once

If a true value is specified for the "allow_with_category_restriction" option, then any "no warnings" that restricts the set of warnings that are turned off will pass.

    [TestingAndDebugging::ProhibitNoWarnings]
    allow_with_category_restriction = 1
