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