Perl::Critic::Policy::Modules::RequireExplicitPackage - Always make the
This Policy is part of the core Perl::Critic distribution.
the first statement of any Perl module or library should be a
all the code that comes before the
package statement is getting executed in the caller's package,
and you have no idea who that is.
Good encapsulation and common decency require your module to keep its innards to itself.
There are some valid reasons for not having a
package statement at all.
But make sure you understand them before assuming that you should do it too.
The maximum number of violations per document for this policy defaults to 1.
As for programs,
most people understand that the default package is
so this Policy doesn't apply to files that begin with a perl shebang.
If you want to require an explicit
package declaration in all files,
then add the following to your .perlcriticrc file
[Modules::RequireExplicitPackage] exempt_scripts = 0
This policy was formerly called
ProhibitUnpackagedCode which sounded a bit odd. If you get lots of "Cannot load policy module" errors, then you probably need to change
RequireExplicitPackage in your .perlcriticrc file.
