Perl::Critic::Policy:Perl::Critic::Policy::Modules::RequireBarewordIncludes(3)NAMEPerl::Critic::Policy::Modules::RequireBarewordIncludes - Write "require
Module" instead of "require 'Module.pm'".
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
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
'*.pl' libraries.
use 'My/Perl/Module.pm'; #not ok
use My::Perl::Module; #ok
CONFIGURATION
This Policy is not configurable except for the standard options.
NOTES
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 don't 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
