NAME

       Perl::Critic::Policy::Subroutines::ProhibitUnusedPrivateSubroutines - Prevent unused private subroutines.

AFFILIATION

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

DESCRIPTION

       By convention Perl authors (like authors in many other languages) indicate private methods and variables by inserting a leading underscore
       before the identifier.  This policy catches such subroutines which are not used in the file which declares them.

       This module defines a 'use' of a subroutine as a subroutine or method call to it (other than from inside the subroutine itself), a
       reference to it (i.e.  "my $foo = &_foo"), a "goto" to it outside the subroutine itself (i.e.  "goto &_foo"), or the use of the
       subroutine's name as an even-numbered argument to "use overload".

CONFIGURATION

       You can define what a private subroutine name looks like by specifying a regular expression for the "private_name_regex" option in your
       .perlcriticrc:

	   [Subroutines::ProhibitUnusedPrivateSubroutines]
	   private_name_regex = _(?!_)w+

       The above example is a way of saying that subroutines that start with a double underscore are not considered to be private.  (Perl::Critic,
       in its implementation, uses leading double underscores to indicate a distribution-private subroutine -- one that is allowed to be invoked
       by other Perl::Critic modules, but not by anything outside of Perl::Critic.)

       You can configure additional subroutines to accept by specifying them in a space-delimited list to the "allow" option:

	   [Subroutines::ProhibitUnusedPrivateSubroutines]
	   allow = _bar _baz

       These are added to the default list of exemptions from this policy. So the above allows "sub _bar {}" and "sub _baz {}", even if they are
       not referred to in the module that defines them.

HISTORY

       This policy is derived from Perl::Critic::Policy::Subroutines::ProtectPrivateSubs, which looks at the other side of the problem.

BUGS

       Does not forbid "sub Foo::_foo{}" because it does not know (and can not assume) what is in the "Foo" package.
