NAME

       Test::Spelling - check for spelling errors in POD files

SYNOPSIS

           use Test::More;
           BEGIN {
               plan skip_all => "Spelling tests only for authors"
                   unless -d 'inc/.author';
           }

           use Test::Spelling;
           all_pod_files_spelling_ok();

DESCRIPTION

       "Test::Spelling" lets you check the spelling of a POD file, and report its results in
       standard "Test::More" fashion. This module requires a spellcheck program such as spell,
       aspell, ispell, or hunspell.

           use Test::Spelling;
           pod_file_spelling_ok('lib/Foo/Bar.pm', 'POD file spelling OK');

       Note that it is a bad idea to run spelling tests during an ordinary CPAN distribution
       install, or in a package that will run in an uncontrolled environment. There is no way of
       predicting whether the word list or spellcheck program used will give the same results.
       You can include the test in your distribution, but be sure to run it only for authors of
       the module by guarding it in a "skip_all unless -d 'inc/.author'" clause, or by putting
       the test in your distribution's xt/ directory. Anyway, people installing your module
       really do not need to run such tests, as it is unlikely that the documentation will
       acquire typos while in transit. :-)

       You can add your own stop words, which are words that should be ignored by the spell
       check, like so:

           add_stopwords(qw(asdf thiswordiscorrect));

       Adding stop words in this fashion affects all files checked for the remainder of the test
       script. See Pod::Spell (which this module is built upon) for a variety of ways to add per-
       file stop words to each .pm file.

       If you have a lot of stop words, it's useful to put them in your test file's "DATA"
       section like so:

           use Test::Spelling;
           add_stopwords(<DATA>);
           all_pod_files_spelling_ok();

           __END__
           folksonomy
           Jifty
           Zakirov

       To maintain backwards compatibility, comment markers and some whitespace are ignored. In
       the near future, the preprocessing we do on the arguments to add_stopwords will be changed
       and documented properly.

FUNCTIONS

   all_pod_files_spelling_ok( [@files/@directories] )
       Checks all the files for POD spelling. It gathers all_pod_files() on each file/directory,
       and declares a "plan" in Test::More for you (one test for each file), so you must not call
       "plan" yourself.

       If @files is empty, the function finds all POD files in the blib directory if it exists,
       or the lib directory if it does not. A POD file is one that ends with .pod, .pl, .plx, or
       .pm; or any file where the first line looks like a perl shebang line.

       If there is no working spellchecker (determined by "has_working_spellchecker"), this test
       will issue a "skip all" directive.

       If you're testing a distribution, just create a t/pod-spell.t with the code in the
       "SYNOPSIS".

       Returns true if every POD file has correct spelling, or false if any of them fail.  This
       function will show any spelling errors as diagnostics.

   pod_file_spelling_ok( $filename[, $testname ] )
       "pod_file_spelling_ok" will test that the given POD file has no spelling errors.

       When it fails, "pod_file_spelling_ok" will show any spelling errors as diagnostics.

       The optional second argument is the name of the test.  If it is omitted,
       "pod_file_spelling_ok" chooses a default test name "POD spelling for $filename".

   all_pod_files( [@dirs] )
       Returns a list of all the Perl files in each directory and its subdirectories,
       recursively. If no directories are passed, it defaults to blib if blib exists, or else lib
       if not. Skips any files in CVS or .svn directories.

       A Perl file is:

       •   Any file that ends in .PL, .pl, .plx, .pm, .pod or .t.

       •   Any file that has a first line with a shebang and "perl" on it.

       Furthermore, files for which the filter set by "set_pod_file_filter" return false are
       skipped. By default, this filter passes everything through.

       The order of the files returned is machine-dependent.  If you want them sorted, you'll
       have to sort them yourself.

   add_stopwords(@words)
       Add words that should be skipped by the spellcheck. Note that Pod::Spell already skips
       words believed to be code, such as everything in verbatim (indented) blocks and code
       marked up with ""..."", as well as some common Perl jargon.

   has_working_spellchecker
       "has_working_spellchecker" will return "undef" if there is no working spellchecker, or a
       true value (the spellchecker command itself) if there is.  The module performs a dry-run
       to determine whether any of the spellcheckers it can will use work on the current system.
       You can use this to skip tests if there is no spellchecker. Note that
       "all_pod_files_spelling_ok" will do this for you.

   set_spell_cmd($command)
       If you want to force this module to use a particular spellchecker, then you can specify
       which one with "set_spell_cmd". This is useful to ensure a more consistent lexicon between
       developers, or if you have an unusual environment.  Any command that takes text from
       standard input and prints a list of misspelled words, one per line, to standard output
       will do.

   set_pod_file_filter($code)
       If your project has POD documents written in languages other than English, then obviously
       you don't want to be running a spellchecker on every Perl file.  "set_pod_file_filter"
       lets you filter out files returned from "all_pod_files" (and hence, the documents tested
       by "all_pod_files_spelling_ok").

           set_pod_file_filter(sub {
               my $filename = shift;
               return 0 if $filename =~ /_ja.pod$/; # skip Japanese translations
               return 1;
           });

   set_pod_parser($object)
       By default Pod::Spell is used to generate text suitable for spellchecking from the input
       POD.  If you want to use a different parser, perhaps a customized subclass of Pod::Spell,
       call "set_pod_parser" with an object that is-a Pod::Parser.  Be sure to create a fresh
       parser object for each file (don't use this with "all_pod_files_spelling_ok").
