NAME
Pod::Spell - a formatter for spellchecking Pod
VERSION
version 1.24
SYNOPSIS
use Pod::Spell;
Pod::Spell->new->parse_from_file( 'File.pm' );
Pod::Spell->new->parse_from_filehandle( $infile, $outfile );
Also look at podspell
% perl -MPod::Spell -e "Pod::Spell->new->parse_from_file(shift)" Thing.pm |spell |fmt
...or instead of piping to spell or "ispell", use ">temp.txt", and open
temp.txt in your word processor for spell-checking.
DESCRIPTION
Pod::Spell is a Pod formatter whose output is good for spellchecking.
Pod::Spell is rather like Pod::Text, except that it doesn't put much
effort into actual formatting, and it suppresses things that look like
Perl symbols or Perl jargon (so that your spellchecking program won't
complain about mystery words like "$thing" or ""Foo::Bar"" or
"hashref").
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.
METHODS
new
Pod::Spell->new(%options)
Creates a new Pod::Spell instance. Accepts several options:
debug
When set to a true value, will output debugging messages about how
the Pod is being processed.
Defaults to false.
stopwords
Can be specified to use an alternate wordlist instance.
Defaults to a new Pod::Wordlist instance.
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.
stopwords
$self->stopwords->isa('Pod::WordList'); # true
parse_from_filehandle($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 "STDIN" is used.
The $in_fh parameter may be any object that provides a getline() method
to retrieve a single line of input text (hence, an appropriate wrapper
object could be used to parse PODs from a single string or an array of
strings).
parse_from_file($filename,$outfile)
This method takes a filename and does the following:
* opens the input and output files for reading (creating the appropriate
filehandles)
* invokes the parse_from_filehandle() method passing it the
corresponding input and output filehandles.
* closes the input and output files.
If the special input filename "", "-" or "<&STDIN" is given then the
STDIN filehandle is used for input (and no open or close is performed).
If no input filename is specified then "-" is implied. Filehandle
references, or objects that support the regular IO operations (like
"<$fh>" or "$fh-<Egt"getline>) are also accepted; the handles must
already be opened.
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
"print", e.g. IO::String) are also accepted; the object must already be
opened.
ENCODINGS
If your Pod is encoded in something other than Latin-1, it should
declare an encoding using the ""=encoding *encodingname*"" in perlpod
directive.
ADDING STOPWORDS
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.
CAVEATS
finding stopwords defined with "=for"
Pod::Spell makes a single pass over the POD. Stopwords must be added
before they show up in the POD.
HINT
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.
