NAME

Perl::Critic::Policy::Compatibility::PodMinimumVersion - check Perl version declared against POD features used

DESCRIPTION

This policy is part of the Perl::Critic::Pulp addon. It checks that the POD features you use don't exceed your target Perl version as indicated by use 5.008 etc.

use 5.005;

=pod

C<< something >>     # bad, no angles before 5.006

POD doesn't affect how the code runs, so this policy is low priority, and under the "compatibility" theme (see "POLICY THEMES" in Perl::Critic).

See Pod::MinimumVersion for the POD version checks applied. The key idea is for instance when targeting Perl 5.005 to avoid using double-angles C<< >>, since pod2man in 5.005 didn't support them. It's always possible to get newer versions of the POD translators from CPAN, but whether they run on an older Perl and whether you want to require that of users is another matter.

Adding the sort of use 5.006 etc to declare a target Perl can be a bit tedious. The config option below lets you set a base version you use. As always if you don't care at all about this sort of thing you can disable the policy from your .perlcriticrc in the usual way,

[-Compatibility::PodMinimumVersion]

Other Notes

J<< >> for Pod::MultiLang is recognised and is allowed for any Perl, including its double-angles. The assumption is that if you're writing that then you'll be crunching it with the Pod::MultiLang tools, so it's not important what pod2man thinks of it.

The Compatibility::RequirePodLinkText policy asks you to use the L<target|display> style always. That feature is new in Perl 5.005 and will be reported by PodMinimumVersion unless you've got use 5.005 or higher or set above_version below.

CONFIGURATION

above_version (version string, default none)

Report only things about Perl versions above this. The string is any version number style version.pm understands. For example if you always use Perl 5.6 or higher then set

[Compatibility::PodMinimumVersion]
above_version = 5.006

The effect is that all POD features up to and including Perl 5.6 are allowed, only things above that will be reported (and still only those exceeding any use 5.xxx in the file).
