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.
