NAME

       Perl::Critic::Policy::Miscellanea::ProhibitUselessNoCritic - Remove ineffective "## no
       critic" annotations.

AFFILIATION

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

DESCRIPTION

       Sometimes, you may need to use a "## no critic" annotation to work around a false-positive
       bug in Perl::Critic.  But eventually, that bug might get fixed, leaving your code with
       extra "## no critic" annotations lying about.  Or you may use them to locally disable a
       Policy, but then later decide to permanently remove that Policy entirely from your
       profile, making some of those "## no critic" annotations pointless.  Or, you may
       accidentally disable too many Policies at once, creating an opportunity for new violations
       to slip in unnoticed.

       This Policy will emit violations if you have a "## no critic" annotation in your source
       code that does not actually suppress any violations given your current profile.  To
       resolve this, you should either remove the annotation entirely, or adjust the Policy name
       patterns in the annotation to match only the Policies that are actually being violated in
       your code.

EXAMPLE

       For example, let's say I have a regex, but I don't want to use the "/x" flag, which
       violates the "RegularExpressions::RequireExtendedFormatting" policy.  In the following
       code, the "## no critic" annotation will suppress violations of that Policy and ALL
       Policies that match "m/RegularExpressions/imx"

         my $re = qr/foo bar baz/ms;  ## no critic (RegularExpressions)

       However, this creates a potential loop-hole for someone to introduce additional violations
       in the future, without explicitly acknowledging them.  This Policy is designed to catch
       these situations by warning you that you've disabled more Policies than the situation
       really requires.  The above code should be remedied like this:

         my $re = qr/foo bar baz/ms;  ## no critic (RequireExtendedFormatting)

       Notice how the "RequireExtendedFormatting" pattern more precisely matches the name of the
       Policy that I'm trying to suppress.

NOTE

       Changing your .perlcriticrc file and disabling policies globally or running at a higher
       (i.e. less restrictive) severity level may cause this Policy to emit additional
       violations.  So you might want to defer using this Policy until you have a fairly stable
       profile.

CONFIGURATION

       This Policy is not configurable except for the standard options.
