Perl::Critic::Policy::Lax::RequireExplicitPackage::ExceptForPragmata

NAME

Perl::Critic::Policy::Lax::RequireExplicitPackage::ExceptForPragmata

VERSION

version 0.008

DESCRIPTION

This policy is meant to replace Modules::RequireExplicitPackage. That policy’s POD says:

  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 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.

Sure, that’s swell for code that has effect at a package level, but some statements are lexical. This policy makes allowance for some of those cases. By default, it permits turning on strictures, warnings, features, and diagnostics, as well as requiring a minimum Perl version.

METHODS

supported_parameters
The default list of pragmata that are permitted before a "package" declaration can be changed via the "allowed_pragmata" configuration parameter. Its value is a space-separated list of pragma names to be permitted. In this list, the name "perlversion" is special: it allows a "use 5.xxx" statement.

This module understands the "exempt_scripts" configuration parameter just like Perl::Critic::Policy::Modules::RequireExplicitPackage.
