Test The Spell Command

NAME

       Perl::Critic::Policy::Documentation::PodSpelling - Check your spelling.

AFFILIATION

       This Policy is part of the core Perl::Critic distribution.

DESCRIPTION

       Did you write the documentation?  Check.

       Did you document all of the public methods?  Check.

       Is your documentation readable?  Hmm...

       Ideally, we'd like Perl::Critic to tell you when your documentation is inadequate.  That's
       hard to code, though.  So, inspired by Test::Spelling, this module checks the spelling of
       your POD.  It does this by pulling the prose out of the code and passing it to an external
       spell checker.  It skips over words you flagged to ignore.  If the spell checker returns
       any misspelled words, this policy emits a violation.

       If anything else goes wrong -- we can't locate the spell checking program or (gasp!) your
       module has no POD -- then this policy passes.

       To add exceptions on a module-by-module basis, add "stopwords" as described in Pod::Spell.
       For example:

           =for stopword gibbles

           =head1 Gibble::Manip -- manipulate your gibbles

           =cut

CONFIGURATION

       This policy can be configured to tell which spell checker to use or to set a global list
       of spelling exceptions.  To do this, put entries in a .perlcriticrc file like this:

           [Documentation::PodSpelling]
           spell_command = aspell list
           stop_words = gibbles foobar
           stop_words_file = some/path/with/stop/words.txt

       The default spell command is "aspell list" and it is interpreted as a shell command.  We
       parse the individual arguments via Text::ParseWords so feel free to use quotes around your
       arguments.  If the executable path is an absolute file name, it is used as-is.  If it is a
       relative file name, we employ File::Which to convert it to an absolute path via the "PATH"
       environment variable.  As described in Pod::Spell and Test::Spelling, the spell checker
       must accept text on STDIN and print misspelled words one per line on STDOUT.

       You can specify global stop words via the "stop_words" and "stop_words_file" options.  The
       former is simply split up on whitespace.  The latter is looked at line by line, with
       anything after an octothorp ("#") removed and then leading and trailing whitespace
       removed.  Silly example valid file contents:

           # It's a comment!

           foo
           arglbargl    # Some other comment.
           bar

       The values from "stop_words" and "stop_words_file" are merged together into a single list
       of exemptions.

NOTES

       A spell checking program is not included with Perl::Critic.

       The results of failures for this policy can be confusing when aspell complains about words
       containing punctuation such as hyphens and apostrophes.  In this situation aspell will
       often only emit part of the word that it thinks is misspelled.  For example, if you ask
       aspell to check "foobie-bletch", the output only complains about "foobie".  Unfortunately,
       you'll have to look through your POD to figure out what the real word that aspell is
       complaining about is.  One thing to try is looking at the output of "perl -MPod::Spell -e
       'print Pod::Spell->new()->parse_from_file("lib/Your/Module.pm")'" to see what is actually
       being checked for spelling.

PREREQUISITES

       This policy will disable itself if File::Which is not available.
