NAME

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

DESCRIPTION

       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
               &foo();

       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,

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

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

       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

           =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).

       "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

   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 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),

           [-Documentation::ProhibitVerbatimMarkup]
