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 &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
=overcan be used for indentation if desired.
You wanted verbatim -- replace the markup with an ascii approximation like
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
The check for markup is unsophisticated. Any of the POD specified "I<" "C<" etc is taken to be markup, plus "J<" of
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<> style sample Perl debugger output is exempted (see perldebug). It's uncommon, but not likely to have intended
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 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),
