Pod::Spell - a formatter for spellchecking Pod
version 1.10
use Pod::Spell; Pod::Spell->new->parse_from_file( 'File.pm' ); Pod::Spell->new->parse_from_filehandle( $infile, $outfile );
Also look at podspell
% perl -MPod::Spell -e "Pod::Spell->new->parse_from_file(shift)" Thing.pm |spell |fmt
...or instead of piping to spell or ispell, use >temp.txt, and open temp.txt in your word processor for spell-checking.
ispell
>temp.txt
Pod::Spell is a Pod formatter whose output is good for spellchecking. Pod::Spell rather like Pod::Text, except that it doesn't put much effort into actual formatting, and it suppresses things that look like Perl symbols or Perl jargon (so that your spellchecking program won't complain about mystery words like "$thing" or "Foo::Bar" or "hashref").
$thing
Foo::Bar
This class provides no new public methods. All methods of interest are inherited from Pod::Parser (which see). The especially interesting ones are parse_from_filehandle (which without arguments takes from STDIN and sends to STDOUT) and parse_from_file. But you can probably just make do with the examples in the synopsis though.
parse_from_filehandle
parse_from_file
This class works by filtering out words that look like Perl or any form of computerese (like "$thing" or "N>7" or "@{$foo}{'bar','baz'}", anything in C<...> or F<...> codes, anything in verbatim paragraphs (code blocks), and anything in the stopword list. The default stopword list for a document starts out from the stopword list defined by Pod::Wordlist, and can be supplemented (on a per-document basis) by having "=for stopwords" / "=for :stopwords" region(s) in a document.
N>7
@{$foo}{'bar','baz'}
"=for stopwords"
"=for :stopwords"
$self->stopwords->isa('Pod::WordList'); # true
Pod::Parser, which Pod::Spell extends, is extremely naive about character encodings. The parse_from_file method does not apply any PerlIO encoding layer. If your Pod file is encoded in UTF-8, your data will be read incorrectly.
You should instead use parse_from_filehandle and manage the input and output layers yourself.
binmode($_, ":utf8") for ($infile, $outfile); $my ps = Pod::Spell->new; $ps->parse_from_filehandle( $infile, $outfile );
If your output destination cannot handle UTF-8, you should set your output handle to Latin-1 and tell Pod::Spell to strip out words with wide characters.
binmode($infile, ":utf8"); binmode($outfile, ":encoding(latin1)"); $my ps = Pod::Spell->new( no_wide_chars => 1 ); $ps->parse_from_filehandle( $infile, $outfile );
NOTE: Pod::Spell makes a single pass over the POD. Stopwords must be added before they show up in the POD.
You can add stopwords on a per-document basis with "=for stopwords" / "=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 Lingua::EN::Inflect. Words beginning with "!" are 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 any case; but if the word has any capital letters, then it means that it's okay only with 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 document:
=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 C<...> or F<...> 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 E<...> sequences in a "stopwords" region, you have to use ":stopwords", as here:
=for :stopwords virtE<ugrave>
...meaning that you're adding a stopword of "virtù". If you left the ":" out, that would mean you were adding a stopword of "virtE<ugrave>" (with a literal E, a literal <, etc), which will have no effect, since any occurrences of virtE<ugrave> don't look like a normal human-language word anyway, and so would be screened out before the stopword list is consulted anyway.
My personal advice:
Write your documentation in Pod. Pod is described in perlpod. And perlmodstyle has some advice on content. This is the stage where you want to make sure you say everything you should, have good and working examples, and have coherent grammar.
Run it through podchecker. This will report all sorts of problems with your Pod; you may choose to ignore some of these problems. Some, like "*** WARNING: Unknown entity E<qacute>...", you should pay attention to.
Once podchecker errors have been tended to, spellcheck the pod by running it through podspell / Pod::Spell. For any misspellings that are reported in the Pod::Spell-formatted text, fix them in the original. Repeat until there's no complaints.
Run it through podchecker again just for good measure.
Pod::Wordlist
Pod::Parser
podchecker also known as Pod::Checker
perlpod, perlpodspec
If you feed output of Pod::Spell into your word processor and run a spell-check, make sure you're 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.
