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


This policy is part of the Perl::Critic::Pulp add-on. 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

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

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


    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).

DB<1> style sample Perl debugger output is exempted (see perldebug). It's uncommon, but not likely to have intended B<> bold.

    DB<123> dump b        # ok


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 works too,

    ## no critic (ProhibitVerbatimMarkup)

But the annotation must be before any __END__ token, and if the POD is after an __END__ token then Perl::Critic 1.112 up is required. An =for has the advantage of being together 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),
