.SH NAME
Perl::Critic::Policy::TestingAndDebugging::ProhibitNoWarnings \- Prohibit various flavors of "no warnings".
.SH AFFILIATION
.IX Header "AFFILIATION"
This Policy is part of the core Perl::Critic
distribution.
.SH DESCRIPTION
.IX Header "DESCRIPTION"
There are good reasons for disabling certain kinds of warnings.  But
if you were wise enough to \f(CW\*(C`use warnings\*(C'\fR in the first place, then it
doesn't make sense to disable them completely.  By default, any
\&\f(CW\*(C`no warnings\*(C'\fR statement will violate this policy.  However, you can
configure this Policy to allow certain types of warnings to be
disabled (See "CONFIGURATION").  A bare \f(CW\*(C`no warnings\*(C'\fR
statement will always raise a violation.
.SH CONFIGURATION
.IX Header "CONFIGURATION"
The permitted warning types can be configured via the \f(CW\*(C`allow\*(C'\fR 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:
.PP
.Vb 2
\&    [TestingAndDebugging::ProhibitNoWarnings]
\&    allow = uninitialized once
.Ve
.PP
If a true value is specified for the
\&\f(CW\*(C`allow_with_category_restriction\*(C'\fR option, then any \f(CW\*(C`no warnings\*(C'\fR
that restricts the set of warnings that are turned off will pass.
.PP
.Vb 2
\&    [TestingAndDebugging::ProhibitNoWarnings]
\&    allow_with_category_restriction = 1
.Ve
