NAME

6       Pod::Wrap - Wrap pod paragraphs, leaving verbatim text and code alone.

SYNOPSIS

9           #!/usr/bin/perl
10
11           use strict;
12           use warnings;
13
14           use Pod::Wrap;
15
16           my $w = new Pod::Wrap;
17
18           unless (@ARGV) {
19               $w->parse_from_filehandle() # STDIN
20           } else {
21               $w->parse_from_file($_) for @ARGV;
22           }
23

DESCRIPTION

25       This is a Pod::Parser subclass, based on Pod::Stripper. It parses perl
26       files, wrapping pod text, and leaving everything else intact. It prints
27       it's output to wherever you point it to (like you do with Pod::Parser
28       (and Pod::Stripper)).
29

METHODS

31       new This is actually "new" in Pod::Parser.
32
33           All arguments to it are meaningless, as they are in Pod::Parser.
34
35       parse_from_filehandle
36       parse_from_file
37           These are actually "parse_from_filehandle" in Pod::Parser and
38           "parse_from_file" in Pod::Parser.
39
40           They will receive input and output as described therein.
41
42           They will invoke this parser class, which will filter the pod text,
43           wrapping the appropriate sections using Text::Wrap.

MOTIVATION

46       I prefer editing with tabs and soft wrapping.
47
48       Most people like getting documentation hard wrapped and with tabs
49       expanded.
50
51       The tabs are easy (Text::Tabs), but wrapping only the correct parts of
52       the pod is a little tricker. This module attempts to do this correctly,
53       by wrapping only what isn't a command, a verbatim example (indented
54       text), or actual Perl code.
55
56       PodMaster noted that I should see what perltidy has to offer. Turns out
57       that
58
59           What perltidy does not parse and format
60           ...
61           And, of course, it does not modify pod documents.
62
63       This drove me to release this tiny module.
64

BEHAVIOR MODIFICATION

66       The wrapping behavior is defined entirely by Text::Wrap.
67
68       No re-exporting is made, in order to minimize bugs. If you want to
69       import the variables Text::Wrap uses, do something like this:
70
71           use Pod::Wrap;
72           use Text::Wrap qw/$columns $huge/;
73

CREDITS

81       Podmaster wrote Pod::Stripper. Even though the functionality of this
82       module is very limited, and is not really derived from Pod::Stripper, I
83       would have been too lazy to read Pod::Parser's docs without seeing
84       Pod::Stripper's code as an example first.
85
86       Bottom line, most of the work (the research) that was actually done is
87       not mine. Implementation wouldn't have happened if I hadn't known for
88       sure it's possible to get perl code, verbatim, out of a pod parser. And
89       I wouldn't have if I hadn't seen a working example.
90
92       You may not wrap pod files in any way without my explicit permission,
93       in writing.
94
95       Just kidding.
