NAME

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

DESCRIPTION

This policy is part of the "Perl::Critic::Pulp" add-on. 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, double angles needs 5.006

POD doesn't affect how the code runs, so this policy is low severity, 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 example when targeting Perl 5.005 you avoid things like double-angles "C<< >>", since "pod2man" in 5.005 didn't support them. It may be 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 (see "CONFIGURATION" in Perl::Critic),

    [-Compatibility::PodMinimumVersion]

"RequirePodLinksIncludeText" Policy

The "Documentation::RequirePodLinksIncludeText" 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 anything the "version.pm" module 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).
