pod2man - translate embedded Perl pod directives into man pages
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
B<pod2man>
|
|
[ B<--section=>I<manext> ]
|
|
[ B<--release=>I<relpatch> ]
|
|
[ B<--center=>I<string> ]
|
|
[ B<--date=>I<string> ]
|
|
[ B<--fixed=>I<font> ]
|
|
[ B<--official> ]
|
|
[ B<--lax> ]
|
|
I<inputfile>
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
B<pod2man> converts its input file containing embedded pod directives (see
|
|
L<perlpod>) into nroff source suitable for viewing with nroff(1) or
|
|
troff(1) using the man(7) macro set.
|
|
|
|
Besides the obvious pod conversions, B<pod2man> also takes care of
|
|
func(), func(n), and simple variable references like $foo or @bar so
|
|
you don't have to use code escapes for them; complex expressions like
|
|
C<$fred{'stuff'}> will still need to be escaped, though. Other nagging
|
|
little roffish things that it catches include translating the minus in
|
|
something like foo-bar, making a long dash--like this--into a real em
|
|
dash, fixing up "paired quotes", putting a little space after the
|
|
parens in something like func(), making C++ and PI look right, making
|
|
double underbars have a little tiny space between them, making ALLCAPS
|
|
a teeny bit smaller in troff(1), and escaping backslashes so you don't
|
|
have to.
|
|
|
|
=head1 OPTIONS
|
|
|
|
=over 8
|
|
|
|
=item center
|
|
|
|
Set the centered header to a specific string. The default is
|
|
"User Contributed Perl Documentation", unless the C<--official> flag is
|
|
given, in which case the default is "Perl Programmers Reference Guide".
|
|
|
|
=item date
|
|
|
|
Set the left-hand footer string to this value. By default,
|
|
the modification date of the input file will be used.
|
|
|
|
=item fixed
|
|
|
|
The fixed font to use for code refs. Defaults to CW.
|
|
|
|
=item official
|
|
|
|
Set the default header to indicate that this page is of
|
|
the standard release in case C<--center> is not given.
|
|
|
|
=item release
|
|
|
|
Set the centered footer. By default, this is the current
|
|
perl release.
|
|
|
|
=item section
|
|
|
|
Set the section for the C<.TH> macro. The standard conventions on
|
|
sections are to use 1 for user commands, 2 for system calls, 3 for
|
|
functions, 4 for devices, 5 for file formats, 6 for games, 7 for
|
|
miscellaneous information, and 8 for administrator commands. This works
|
|
best if you put your Perl man pages in a separate tree, like
|
|
F</usr/local/perl/man/>. By default, section 1 will be used
|
|
unless the file ends in F<.pm> in which case section 3 will be selected.
|
|
|
|
=item lax
|
|
|
|
Don't complain when required sections aren't present.

=head1 Anatomy of a Proper Man Page
|
|
|
|
For those not sure of the proper layout of a man page, here's
|
|
an example of the skeleton of a proper man page. Head of the
|
|
major headers should be setout as a C<=head1> directive, and
|
|
are historically written in the rather startling ALL UPPER CASE
|
|
format, although this is not mandatory.
|
|
Minor headers may be included using C<=head2>, and are
|
|
typically in mixed case.
|
|
|
|
=over 10
|
|
|
|
=item NAME
|
|
|
|
Mandatory section; should be a comma-separated list of programs or
|
|
functions documented by this podpage, such as:
|
|
|
|
foo, bar - programs to do something
|
|
|
|
=item SYNOPSIS
|
|
|
|
A short usage summary for programs and functions, which
|
|
may someday be deemed mandatory.
|
|
|
|
=item DESCRIPTION
|
|
|
|
Long drawn out discussion of the program. It's a good idea to break this
|
|
up into subsections using the C<=head2> directives, like
|
|
|
|
=head2 A Sample Subection
|
|
|
|
=head2 Yet Another Sample Subection
|
|
|
|
=item OPTIONS
|
|
|
|
Some people make this separate from the description.
|
|
|
|
=item RETURN VALUE
|
|
|
|
What the program or function returns if successful.
|
|
|
|
=item ERRORS
|
|
|
|
Exceptions, return codes, exit stati, and errno settings.
|
|
|
|
=item EXAMPLES
|
|
|
|
Give some example uses of the program.
|
|
|
|
=item ENVIRONMENT
|
|
|
|
Envariables this program might care about.
|
|
|
|
=item FILES
|
|
|
|
All files used by the program. You should probably use the FE<lt>E<gt>
|
|
for these.
|
|
|
|
=item SEE ALSO
|
|
|
|
Other man pages to check out, like man(1), man(7), makewhatis(8), or catman(8).
|
|
|
|
=item NOTES
|
|
|
|
Miscellaneous commentary.
|
|
|
|
=item CAVEATS
|
|
|
|
Things to take special care with; sometimes called WARNINGS.
|
|
|
|
=item DIAGNOSTICS
|
|
|
|
All possible messages the program can print out--and
|
|
what they mean.
|
|
|
|
=item BUGS
|
|
|
|
Things that are broken or just don't work quite right.
|
|
|
|
=item RESTRICTIONS
|
|
|
|
Bugs you don't plan to fix :-)
|
|
|
|
=item AUTHOR
|
|
|
|
Who wrote it (or AUTHORS if multiple).
|
|
|
|
=item HISTORY
|
|
|
|
Programs derived from other sources sometimes have this, or
|
|
you might keep a modification log here.

=head1 EXAMPLES

|
|
|
|
=head1 DIAGNOSTICS
|
|
|
|
The following diagnostics are generated by B<pod2man>. Items
|
|
marked "(W)" are non-fatal, whereas the "(F)" errors will cause
|
|
B<pod2man> to immediately exit with a non-zero status.
|
|
|
|
=over 4
|
|
|
|
=item bad option in paragraph %d of %s: ``%s'' should be [%s]<%s>
|
|
|
|
(W) If you start include an option, you should set it off
|
|
as bold, italic, or code.
|
|
|
|
=item can't open %s: %s
|
|
|
|
(F) The input file wasn't available for the given reason.
|
|
|
|
=item Improper man page - no dash in NAME header in paragraph %d of %s
|
|
|
|
(W) The NAME header did not have an isolated dash in it. This is
|
|
considered important.
|
|
|
|
=item Invalid man page - no NAME line in %s
|
|
|
|
(F) You did not include a NAME header, which is essential.
|
|
|
|
=item roff font should be 1 or 2 chars, not `%s' (F)
|
|
|
|
(F) The font specified with the C<--fixed> option was not
|
|
a one- or two-digit roff font.
|
|
|
|
=item %s is missing required section: %s
|
|
|
|
(W) Required sections include NAME, DESCRIPTION, and if you're
|
|
using a section starting with a 3, also a SYNOPSIS. Actually,
|
|
not having a NAME is a fatal.
|
|
|
|
=item Unknown escape: %s in %s
|
|
|
|
(W) An unknown HTML entity (probably for an 8-bit character) was given via
|
|
a C<EE<lt>E<gt>> directive. Besides amp, lt, gt, and quot, recognized
|
|
entities are Aacute, aacute, Acirc, acirc, AElig, aelig, Agrave, agrave,
|
|
Aring, aring, Atilde, atilde, Auml, auml, Ccedil, ccedil, Eacute, eacute,
|
|
Ecirc, ecirc, Egrave, egrave, ETH, eth, Euml, euml, Iacute, iacute, Icirc,
|
|
icirc, Igrave, igrave, Iuml, iuml, Ntilde, ntilde, Oacute, oacute, Ocirc,
|
|
ocirc, Ograve, ograve, Oslash, oslash, Otilde, otilde, Ouml, ouml, szlig,
|
|
THORN, thorn, Uacute, uacute, Ucirc, ucirc, Ugrave, ugrave, Uuml, uuml,
|
|
Yacute, yacute, and yuml.
|
|
|
|
=item Unmatched =back
|
|
|
|
(W) You have a C<=back> without a corresponding C<=over>.
|
|
|
|
=item Unrecognized pod directive: %s
|
|
|
|
(W) You specified a pod directive that isn't in the known list of
|
|
C<=head1>, C<=head2>, C<=item>, C<=over>, C<=back>, or C<=cut>.

|
=head1 NOTES
|
|
|
|
If you would like to print out a lot of man page continuously, you
|
|
probably want to set the C and D registers to set contiguous page
|
|
numbering and even/odd paging, at least on some versions of man(7).
|
|
Settting the F register will get you some additional experimental
|
|
indexing:
|
|
|
|
troff -man -rC1 -rD1 -rF1 perl.1 perldata.1 perlsyn.1 ...
|
|
|
|
The indexing merely outputs messages via C<.tm> for each
|
|
major page, section, subsection, item, and any C<XE<lt>E<gt>>
|
|
directives.
|
|
|
|
|
|
=head1 RESTRICTIONS
|
|
|
|
None at this time.
|
|
|
|
=head1 BUGS
|
|
|
|
The =over and =back directives don't really work right. They
|
|
take absolute positions instead of offsets, don't nest well, and
|
|
making people count is suboptimal in any event.
|
|
|
|

Original prototype by Larry Wall, but so massively hacked over by

Tom Christiansen such that Larry probably doesn't recognize it anymore.
