Manual Reference Pages - PERL::CRITIC::POLICY::MODULES::REQUIREBAREWORDINCLUDES (3)
Perl::Critic::Policy::Modules::RequireBarewordIncludes - Write "require Module" instead of "require Module.pm".
This Policy is part of the core Perl::Critic
When including another module (or library) via the require or
use statements, it is best to identify the module (or library)
using a bareword rather than an explicit path. This is because paths
are usually not portable from one machine to another. Also, Perl
automatically assumes that the filename ends in .pm when the library
is expressed as a bareword. So as a side-effect, this Policy
encourages people to write *.pm modules instead of the old-school
use My/Perl/Module.pm; #not ok
use My::Perl::Module; #ok
This Policy is not configurable except for the standard options.
This Policy is a replacement for ProhibitRequireStatements, which
completely banned the use of require for the sake of eliminating
the old *.pl libraries from Perl4. Upon further consideration, I
realized that require is quite useful and necessary to enable
run-time loading. Thus, RequireBarewordIncludes does allow you to
use require, but still encourages you to write *.pm modules.
Sometimes, you may want to load modules at run-time, but you dont
know at design-time exactly which module you will need to load
(Perl::Critic is an example of this). In that case,
just attach the ## no critic annotation like so:
require $module_name; ## no critic

correct motivation for and behavior of this Policy. Thanks Chris.
