43 pod2man - translate embedded Perl pod directives into man pages
48 [ B<--section=>I<manext> ]
49 [ B<--release=>I<relpatch> ]
50 [ B<--center=>I<string> ]
51 [ B<--date=>I<string> ]
52 [ B<--fixed=>I<font> ]
59 B<pod2man> converts its input file containing embedded pod directives (see
60 L<perlpod>) into nroff source suitable for viewing with nroff(1) or
61 troff(1) using the man(7) macro set.
63 Besides the obvious pod conversions, B<pod2man> also takes care of
64 func(), func(n), and simple variable references like $foo or @bar so
65 you don't have to use code escapes for them; complex expressions like
66 C<$fred{'stuff'}> will still need to be escaped, though. Other nagging
67 little roffish things that it catches include translating the minus in
68 something like foo-bar, making a long dash--like this--into a real em
69 dash, fixing up "paired quotes", putting a little space after the
70 parens in something like func(), making C++ and PI look right, making
71 double underbars have a little tiny space between them, making ALLCAPS
72 a teeny bit smaller in troff(1), and escaping backslashes so you don't
81 Set the centered header to a specific string. The default is
82 "User Contributed Perl Documentation", unless the C<--official> flag is
83 given, in which case the default is "Perl Programmers Reference Guide".
87 Set the left-hand footer string to this value. By default,
88 the modification date of the input file will be used.
92 The fixed font to use for code refs. Defaults to CW.
96 Set the default header to indicate that this page is of
97 the standard release in case C<--center> is not given.
101 Set the centered footer. By default, this is the current
106 Set the section for the C<.TH> macro. The standard conventions on
107 sections are to use 1 for user commands, 2 for system calls, 3 for
108 functions, 4 for devices, 5 for file formats, 6 for games, 7 for
109 miscellaneous information, and 8 for administrator commands. This works
110 best if you put your Perl man pages in a separate tree, like
111 F</usr/local/perl/man/>. By default, section 1 will be used
112 unless the file ends in F<.pm> in which case section 3 will be selected.
116 Don't complain when required sections aren't present.
120 =head1 Anatomy of a Proper Man Page
122 For those not sure of the proper layout of a man page, here's
123 an example of the skeleton of a proper man page. Head of the
124 major headers should be setout as a C<=head1> directive, and
125 are historically written in the rather startling ALL UPPER CASE
126 format, although this is not mandatory.
127 Minor headers may be included using C<=head2>, and are
128 typically in mixed case.
134 Mandatory section; should be a comma-separated list of programs or
135 functions documented by this podpage, such as:
137 foo, bar - programs to do something
141 A short usage summary for programs and functions, which
142 may someday be deemed mandatory.
146 Long drawn out discussion of the program. It's a good idea to break this
147 up into subsections using the C<=head2> directives, like
149 =head2 A Sample Subection
151 =head2 Yet Another Sample Subection
155 Some people make this separate from the description.
159 What the program or function returns if successful.
163 Exceptions, return codes, exit stati, and errno settings.
167 Give some example uses of the program.
171 Envariables this program might care about.
175 All files used by the program. You should probably use the FE<lt>E<gt>
180 Other man pages to check out, like man(1), man(7), makewhatis(8), or catman(8).
184 Miscellaneous commentary.
188 Things to take special care with; sometimes called WARNINGS.
192 All possible messages the program can print out--and
197 Things that are broken or just don't work quite right.
201 Bugs you don't plan to fix :-)
205 Who wrote it (or AUTHORS if multiple).
209 Programs derived from other sources sometimes have this, or
210 you might keep a modification log here.
216 pod2man program > program.1
217 pod2man some_module.pm > /usr/perl/man/man3/some_module.3
218 pod2man --section=7 note.pod > note.7
222 The following diagnostics are generated by B<pod2man>. Items
223 marked "(W)" are non-fatal, whereas the "(F)" errors will cause
224 B<pod2man> to immediately exit with a non-zero status.
228 =item bad option in paragraph %d of %s: ``%s'' should be [%s]<%s>
230 (W) If you start include an option, you should set it off
231 as bold, italic, or code.
233 =item can't open %s: %s
235 (F) The input file wasn't available for the given reason.
237 =item Improper man page - no dash in NAME header in paragraph %d of %s
239 (W) The NAME header did not have an isolated dash in it. This is
240 considered important.
242 =item Invalid man page - no NAME line in %s
244 (F) You did not include a NAME header, which is essential.
246 =item roff font should be 1 or 2 chars, not `%s' (F)
248 (F) The font specified with the C<--fixed> option was not
249 a one- or two-digit roff font.
251 =item %s is missing required section: %s
253 (W) Required sections include NAME, DESCRIPTION, and if you're
254 using a section starting with a 3, also a SYNOPSIS. Actually,
255 not having a NAME is a fatal.
257 =item Unknown escape: %s in %s
259 (W) An unknown HTML entity (probably for an 8-bit character) was given via
260 a C<EE<lt>E<gt>> directive. Besides amp, lt, gt, and quot, recognized
261 entities are Aacute, aacute, Acirc, acirc, AElig, aelig, Agrave, agrave,
262 Aring, aring, Atilde, atilde, Auml, auml, Ccedil, ccedil, Eacute, eacute,
263 Ecirc, ecirc, Egrave, egrave, ETH, eth, Euml, euml, Iacute, iacute, Icirc,
264 icirc, Igrave, igrave, Iuml, iuml, Ntilde, ntilde, Oacute, oacute, Ocirc,
265 ocirc, Ograve, ograve, Oslash, oslash, Otilde, otilde, Ouml, ouml, szlig,
266 THORN, thorn, Uacute, uacute, Ucirc, ucirc, Ugrave, ugrave, Uuml, uuml,
267 Yacute, yacute, and yuml.
269 =item Unmatched =back
271 (W) You have a C<=back> without a corresponding C<=over>.
273 =item Unrecognized pod directive: %s
275 (W) You specified a pod directive that isn't in the known list of
276 C<=head1>, C<=head2>, C<=item>, C<=over>, C<=back>, or C<=cut>.
283 If you would like to print out a lot of man page continuously, you
284 probably want to set the C and D registers to set contiguous page
285 numbering and even/odd paging, at least on some versions of man(7).
286 Settting the F register will get you some additional experimental
289 troff -man -rC1 -rD1 -rF1 perl.1 perldata.1 perlsyn.1 ...
291 The indexing merely outputs messages via C<.tm> for each
292 major page, section, subsection, item, and any C<XE<lt>E<gt>>
302 The =over and =back directives don't really work right. They
303 take absolute positions instead of offsets, don't nest well, and
304 making people count is suboptimal in any event.
308 Original prototype by Larry Wall, but so massively hacked over by
309 Tom Christiansen such that Larry probably doesn't recognize it anymore.
