Manual Reference Pages - PERL::CRITIC::POLICY::MODULES::REQUIREEXPLICITPACKAGE (3)
Perl::Critic::Policy::Modules::RequireExplicitPackage - Always make the "package" explicit.
This Policy is part of the core Perl::Critic
In general, the first statement of any Perl module or library should
be a package statement. Otherwise, all the code that comes before
the package statement is getting executed in the callers 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
As for programs, most people understand that the default package is
main, so this Policy doesnt apply to files that begin with a perl
shebang. If you want to require an explicit package declaration in
all files, including programs, then add the following to your
exempt_scripts = 0
Some users may find it desirable to exempt the load of specific modules
from this policy. For example, Perl does not support Unicode module
names because of portability problems. Users who are not concerned about
this and intend to use UTF-8 module names will need to specify
use utf8; before the package declaration. To do this, add the
following to your .perlcriticrc file
allow_import_of = utf8
The allow_import_of configuration option takes multiple module names,
separated by spaces.
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 ProhibitUnpackagedCode to
RequireExplicitPackage in your .perlcriticrc file.
