Perl::Critic::Policy::Documentation::ProhibitVerbatimMarkup

NAME

Perl::Critic::Policy::Documentation::ProhibitVerbatimMarkup − unexpanded C<> etc markup in POD verbatim paras

DESCRIPTION

This policy is part of the "Perl::Critic::Pulp" addon. It reports POD verbatim paragraphs which contain markup like B<> or C<>. That markup will appear literally in the formatted output where you may have meant fontification.

    =head1 SOME THING
    Paragraph of text introducing an example,
        # call the C<foo> function      # bad
        &foo();

This is purely cosmetic so this policy is low priority and under the "cosmetic" theme (see " POLICY THEMES " in Perl::Critic). Normally it means one of two things,

You wanted markup -- it should be a plain paragraph not a verbatim indented one. An "=over" can be used for indentation if desired.

You wanted verbatim -- replace the markup with an ascii approximation like "func()" or even "*bold*" or "_underline_".

Don’t forget a verbatim paragraph extends to the next blank line and includes unindented lines until then (see "Pod Definitions" in perlpodspec). If you forget the blank the verbatimness continues

    =pod
        $some−>sample;
        code();
    And this was I<meant> to be plain text.    # bad

Markup Forms
The check for markup is unsophisticated. Any of the POD specified "I<" "C<" etc is taken to be markup, plus "J<" of "Pod::MultiLang".

    I<       # bad
    B<       # bad
    C<       # bad
    L<       # bad
    E<       # bad
    F<       # bad
    S<       # bad
    X<       # bad
    Z<       # bad
    J<       # bad, for Pod::MultiLang

It’s possible a "<" might be something mathematical like "X<Y", but in practice spaces "X < Y" or lower case letters are more common and are ok.

Sample debugger output is exempted. It’s uncommon, but not likely to have intended "B<>" bold.

    DB<123> dump b        # ok

Disabling
If a verbatim paragraph is showing how to write POD markup then you can add an "=for" to tell ProhibitVerbatimMarkup to allow it. This happens most often in documentation for modules which themselves operate on POD markup.

    =for ProhibitVerbatimMarkup allow next
        blah blah E<gt> etc
    =for ProhibitVerbatimMarkup allow next 2
        Two verbatims of C<code>
        or B<bold> etc

The usual no critic

    ## no critic (ProhibitVerbatimMarkup)

works too, but if the POD is after an "__END__" token then "Perl::Critic" 1.112 is required, and the annotation must be before the "__END__". An "=for" has the advantage of being with the exception.

As always if you don’t care at all about this at all then disable "ProhibitVerbatimMarkup" from your .perlcriticrc in the usual way (see " CONFIGURATION " in Perl::Critic),
