=head1 NAME

Pod::Spell - a formatter for spellchecking Pod

=head1 VERSION

version 1.26


    use Pod::Spell;
    Pod::Spell->new->parse_from_file( '' );

    Pod::Spell->new->parse_from_filehandle( $infile, $outfile );

Also look at L<podspell>

    % perl -MPod::Spell -e "Pod::Spell->new->parse_from_file(shift)" |spell |fmt

...or instead of piping to spell or C<ispell>, use C<< >temp.txt >>, and open
F<temp.txt> in your word processor for spell-checking.


Pod::Spell is a Pod formatter whose output is good for
spellchecking.  Pod::Spell is rather like L<Pod::Text>, except that
it doesn't put much effort into actual formatting, and it suppresses things
that look like Perl symbols or Perl jargon (so that your spellchecking
program won't complain about mystery words like "C<$thing>"
or "C<Foo::Bar>" or "hashref").

This class works by filtering out words that look like Perl or any
form of computerese (like "C<$thing>" or "C<< N>7 >>" or
"C<@{$foo}{'bar','baz'}>", anything in CE<lt>...E<gt> or FE<lt>...E<gt>
codes, anything in verbatim paragraphs (code blocks), and anything
in the stopword list.  The default stopword list for a document starts
out from the stopword list defined by L<Pod::Wordlist>,
and can be supplemented (on a per-document basis) by having
C<"=for stopwords"> / C<"=for :stopwords"> region(s) in a document.

=head1 METHODS

=head2 new


Creates a new Pod::Spell instance. Accepts several options:

=over 4

=item debug

When set to a true value, will output debugging messages about how the Pod
is being processed.

Defaults to false.

=item stopwords

Can be specified to use an alternate wordlist instance.

Defaults to a new Pod::Wordlist instance.

=item no_wide_chars

Will be passed to Pod::Wordlist when creating a new instance. Causes all words
with characters outside the Latin-1 range to be stripped from the output.


=head2 stopwords

    $self->stopwords->isa('Pod::WordList'); # true

=head2 parse_from_filehandle($in_fh,$out_fh)

This method takes an input filehandle (which is assumed to already be
opened for reading) and reads the entire input stream looking for blocks
(paragraphs) of POD documentation to be processed. If no first argument
is given the default input filehandle C<STDIN> is used.

The C<$in_fh> parameter may be any object that provides a B<getline()>
method to retrieve a single line of input text (hence, an appropriate
wrapper object could be used to parse PODs from a single string or an
array of strings).

=head2 parse_from_file($filename,$outfile)

This method takes a filename and does the following:

=over 2

=item *

opens the input and output files for reading
(creating the appropriate filehandles)

=item *

invokes the B<parse_from_filehandle()> method passing it the
corresponding input and output filehandles.

=item *

closes the input and output files.


If the special input filename "", "-" or "<&STDIN" is given then the STDIN
filehandle is used for input (and no open or close is performed). If no
input filename is specified then "-" is implied. Filehandle references,
or objects that support the regular IO operations (like C<E<lt>$fhE<gt>>
or C<$fh-<Egt>getline>) are also accepted; the handles must already be

If a second argument is given then it should be the name of the desired
output file. If the special output filename "-" or ">&STDOUT" is given
then the STDOUT filehandle is used for output (and no open or close is
performed). If the special output filename ">&STDERR" is given then the
STDERR filehandle is used for output (and no open or close is
performed). If no output filehandle is currently in use and no output
filename is specified, then "-" is implied.
Alternatively, filehandle references or objects that support the regular
IO operations (like C<print>, e.g. L<IO::String>) are also accepted;
the object must already be opened.


If your Pod is encoded in something other than Latin-1, it should declare
an encoding using the L<< perlpod/C<=encoding I<encodingname>> >> directive.


You can add stopwords on a per-document basis with
C<"=for stopwords"> / C<"=for :stopwords"> regions, like so:

    =for stopwords  plok Pringe zorch   snik !qux
    foo bar baz quux quuux

This adds every word in that paragraph after "stopwords" to the
stopword list, effective for the rest of the document.  In such a
list, words are whitespace-separated.  (The amount of whitespace
doesn't matter, as long as there's no blank lines in the middle
of the paragraph.)  Plural forms are added automatically using
L<Lingua::EN::Inflect>. Words beginning with "!" are
I<deleted> from the stopword list -- so "!qux" deletes "qux" from the
stopword list, if it was in there in the first place.  Note that if
a stopword is all-lowercase, then it means that it's okay in I<any>
case; but if the word has any capital letters, then it means that
it's okay I<only> with I<that> case.  So a Wordlist entry of "perl"
would permit "perl", "Perl", and (less interestingly) "PERL", "pERL",
"PerL", et cetera.  However, a Wordlist entry of "Perl" catches
only "Perl", not "perl".  So if you wanted to make sure you said
only "Perl", never "perl", you could add this to the top of your

    =for stopwords !perl Perl

Then all instances of the word "Perl" would be weeded out of the
Pod::Spell-formatted version of your document, but any instances of
the word "perl" would be left in (unless they were in a CE<lt>...> or
FE<lt>...> style).

You can have several "=for stopwords" regions in your document.  You
can even express them like so:

    =begin stopwords

    plok Pringe zorch

    snik !qux

    foo bar
    baz quux quuux

    =end stopwords

If you want to use EE<lt>...> sequences in a "stopwords" region, you
have to use ":stopwords", as here:

    =for :stopwords

...meaning that you're adding a stopword of "virtE<ugrave>".  If
you left the ":" out, that would mean you were adding a stopword of
"virtEE<lt>ugrave>" (with a literal E, a literal <, etc), which
will have no effect, since  any occurrences of virtEE<lt>ugrave>
don't look like a normal human-language word anyway, and so would
be screened out before the stopword list is consulted anyway.

=head1 CAVEATS

=head2 finding stopwords defined with C<=for>

Pod::Spell makes a single pass over the POD.  Stopwords
must be added B<before> they show up in the POD.

=head1 HINT

If you feed output of Pod::Spell into your word processor and run a
spell-check, make sure you're I<not> also running a grammar-check -- because
Pod::Spell drops words that it thinks are Perl symbols, jargon, or
stopwords, this means you'll have ungrammatical sentences, what with
words being missing and all.  And you don't need a grammar checker
to tell you that.
