=head1 NAME

Perl::Critic::Policy::Miscellanea::ProhibitUnrestrictedNoCritic - Forbid a bare C<## no critic>


=head1 AFFILIATION

This Policy is part of the core L<Perl::Critic|Perl::Critic>
distribution.


=head1 DESCRIPTION

A bare C<## no critic> annotation will disable B<all> the active Policies.  This
creates holes for other, unintended violations to appear in your code.  It is
better to disable B<only> the particular Policies that you need to get around.
By putting Policy names in a comma-separated list after the C<## no critic>
annotation, then it will only disable the named Policies.  Policy names are
matched as regular expressions, so you can use shortened Policy names, or
patterns that match several Policies. This Policy generates a violation any
time that an unrestricted C<## no critic> annotation appears.

    ## no critic                     # not ok
    ## no critic ''                  # not ok
    ## no critic ()                  # not ok
    ## no critic qw()                # not ok

    ## no critic   (Policy1, Policy2)  # ok
    ## no critic   (Policy1 Policy2)   # ok (can use spaces to separate)
    ## no critic qw(Policy1 Policy2)   # ok (the preferred style)


=head1 NOTE

Unfortunately, L<Perl::Critic|Perl::Critic> is very sloppy about
parsing the Policy names that appear after a C<##no critic>
annotation.  For example, you might be using one of these
broken syntaxes...

    ## no critic Policy1 Policy2
    ## no critic 'Policy1, Policy2'
    ## no critic "Policy1, Policy2"
    ## no critic "Policy1", "Policy2"

In all of these cases, Perl::Critic will silently disable B<all> Policies,
rather than just the ones you requested.  But if you use the
C<ProhibitUnrestrictedNoCritic> Policy, all of these will generate
violations.  That way, you can track them down and correct them to use
the correct syntax, as shown above in the L<"DESCRIPTION">.  If you've
been using the syntax that is shown throughout the Perl::Critic
documentation for the last few years, then you should be fine.


=head1 CONFIGURATION

This Policy is not configurable except for the standard options.
