Test::Spelling(3) User Contributed Perl Documentation Test::Spelling(3)NAMETest::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__

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;
});
