NAME

       Perl::Critic::Policy::Modules::ProhibitEvilModules - Ban modules that aren't blessed by your shop.

AFFILIATION

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

DESCRIPTION

       Use this policy if you wish to prohibit the use of specific modules.  These may be modules that you feel
       are deprecated, buggy, unsupported, insecure, or just don't like.

CONFIGURATION

       The set of prohibited modules is configurable via the "modules" and "modules_file" options.

       The value of "modules" should be a string of space-delimited, fully qualified module names and/or regular
       expressions.  An example of prohibiting two specific modules in a .perlcriticrc file:

           [Modules::ProhibitEvilModules]
           modules = Getopt::Std Autoload

       Regular expressions are identified by values beginning and ending with slashes.  Any module with a name
       that matches "m/pattern/" will be forbidden.  For example:

           [Modules::ProhibitEvilModules]
           modules = /Acme::/

       would cause all modules that match "m/Acme::/" to be forbidden.

       In addition, you can override the default message ("Prohibited module "module" used") with your own, in
       order to give suggestions for alternative action.  To do so, put your message in curly braces after the
       module name or regular expression.  Like this:

           [Modules::ProhibitEvilModules]
           modules = Fatal {Found use of Fatal. Use autodie instead} /Acme::/ {We don't use joke modules}

       Similarly, the "modules_file" option gives the name of a file containing specifications for prohibited
       modules.  Only one module specification is allowed per line and comments start with an octothorp and run
       to end of line; no curly braces are necessary for delimiting messages:

           Evil     # Prohibit the "Evil" module and use the default message.

           # Prohibit the "Fatal" module and give a replacement message.
           Fatal Found use of Fatal. Use autodie instead.

           # Use a regular expression.
           /Acme::/     We don't use joke modules.

       By default, the modules that have been deprecated by the Perl 5 Porters are reported; at the time of
       writing these are Class::ISA, Pod::Plainer, Shell, and Switch.  Specifying a value for the "modules"
       option will override this.

NOTES

       Note that this policy doesn't apply to pragmas.
