ppoodd22mmaann is a front-end for Pod::Man, using it to generate *roff input
from POD source. The resulting *roff code is suitable for display on a
terminal using nnrrooffff(1), normally via mmaann(1), or printing using ttrrooffff(1).
_i_n_p_u_t is the file to read for POD source (the POD can be embedded in
code). If _i_n_p_u_t isn't given, it defaults to "STDIN". _o_u_t_p_u_t, if given,
is the file to which to write the formatted output. If _o_u_t_p_u_t isn't
given, the formatted output is written to "STDOUT". Several POD files
can be processed in the same ppoodd22mmaann invocation (saving module load and
compile times) by providing multiple pairs of _i_n_p_u_t and _o_u_t_p_u_t files on
the command line.
----sseeccttiioonn, ----rreelleeaassee, ----cceenntteerr, ----ddaattee, and ----ooffffiicciiaall can be used to set
the headers and footers to use; if not given, Pod::Man will assume
various defaults. See below or Pod::Man for details.
ppoodd22mmaann assumes that your *roff formatters have a fixed-width font named
"CW". If yours is called something else (like "CR"), use ----ffiixxeedd to
specify it. This generally only matters for troff output for printing.
Similarly, you can set the fonts used for bold, italic, and bold italic
fixed-width output.
Besides the obvious pod conversions, Pod::Man, and therefore pod2man also
takes care of formatting ffuunncc(()), func(n), and simple variable references
like $foo or @bar so you don't have to use code escapes for them; complex
expressions like $fred{'stuff'} will still need to be escaped, though.
It also translates dashes that aren't used as hyphens into en dashes,
makes long dashes--like this--into proper em dashes, fixes "paired
quotes," and takes care of several other troff-specific tweaks. See
Pod::Man for complete information.
OOPPTTIIOONNSS #
--cc _s_t_r_i_n_g, ----cceenntteerr=_s_t_r_i_n_g
Sets the centered page header for the ".TH" macro to _s_t_r_i_n_g. The
default is "User Contributed Perl Documentation", but also see
----ooffffiicciiaall below.
--dd _s_t_r_i_n_g, ----ddaattee=_s_t_r_i_n_g
Set the left-hand footer string for the ".TH" macro to _s_t_r_i_n_g. By
default, the modification date of the input file will be used, or the
current date if input comes from "STDIN", and will be based on UTC
(so that the output will be reproducible regardless of local time
zone).
----eerrrroorrss=_s_t_y_l_e
Set the error handling style. "die" says to throw an exception on
any POD formatting error. "stderr" says to report errors on standard
error, but not to throw an exception. "pod" says to include a POD
ERRORS section in the resulting documentation summarizing the errors.
"none" ignores POD errors entirely, as much as possible.
The default is "die".
----ffiixxeedd=_f_o_n_t
The fixed-width font to use for verbatim text and code. Defaults to
"CW". Some systems may want "CR" instead. Only matters for ttrrooffff(1)
output.
----ffiixxeeddbboolldd=_f_o_n_t
Bold version of the fixed-width font. Defaults to "CB". Only
matters for ttrrooffff(1) output.
----ffiixxeeddiittaalliicc=_f_o_n_t
Italic version of the fixed-width font (actually, something of a
misnomer, since most fixed-width fonts only have an oblique version,
not an italic version). Defaults to "CI". Only matters for ttrrooffff(1)
output.
----ffiixxeeddbboollddiittaalliicc=_f_o_n_t
Bold italic (probably actually oblique) version of the fixed-width
font. Pod::Man doesn't assume you have this, and defaults to "CB".
Some systems (such as Solaris) have this font available as "CX".
Only matters for ttrrooffff(1) output.
--hh, ----hheellpp
Print out usage information.
--ll, ----llaaxx
No longer used. ppoodd22mmaann used to check its input for validity as a
manual page, but this should now be done by ppooddcchheecckkeerr(1) instead.
Accepted for backward compatibility; this option no longer does
anything.
----llqquuoottee=_q_u_o_t_e
----rrqquuoottee=_q_u_o_t_e
Sets the quote marks used to surround C<> text. ----llqquuoottee sets the
left quote mark and ----rrqquuoottee sets the right quote mark. Either may
also be set to the special value "none", in which case no quote mark
is added on that side of C<> text (but the font is still changed for
troff output).
Also see the ----qquuootteess option, which can be used to set both quotes at
once. If both ----qquuootteess and one of the other options is set, ----llqquuoottee
or ----rrqquuoottee overrides ----qquuootteess.
--nn _n_a_m_e, ----nnaammee=_n_a_m_e
Set the name of the manual page for the ".TH" macro to _n_a_m_e. Without
this option, the manual name is set to the uppercased base name of
the file being converted unless the manual section is 3, in which
case the path is parsed to see if it is a Perl module path. If it
is, a path like ".../lib/Pod/Man.pm" is converted into a name like
"Pod::Man". This option, if given, overrides any automatic
determination of the name.
Although one does not have to follow this convention, be aware that
the convention for UNIX man pages for commands is for the man page
title to be in all-uppercase, even if the command isn't.
This option is probably not useful when converting multiple POD files
at once.
When converting POD source from standard input, the name will be set
to "STDIN" if this option is not provided. Providing this option is
strongly recommended to set a meaningful manual page name.
----nnoouurrllss
Normally, L<> formatting codes with a URL but anchor text are
formatted to show both the anchor text and the URL. In other words:
L<foo|http://example.com/>
is formatted as:
foo <http://example.com/>
This flag, if given, suppresses the URL when anchor text is given, so
this example would be formatted as just "foo". This can produce less
cluttered output in cases where the URLs are not particularly
important.
--oo, ----ooffffiicciiaall
Set the default header to indicate that this page is part of the
standard Perl release, if ----cceenntteerr is not also given.
--qq _q_u_o_t_e_s, ----qquuootteess=_q_u_o_t_e_s
Sets the quote marks used to surround C<> text to _q_u_o_t_e_s. If _q_u_o_t_e_s
is a single character, it is used as both the left and right quote.
Otherwise, it is split in half, and the first half of the string is
used as the left quote and the second is used as the right quote.
_q_u_o_t_e_s may also be set to the special value "none", in which case no
quote marks are added around C<> text (but the font is still changed
for troff output).
Also see the ----llqquuoottee and ----rrqquuoottee options, which can be used to set
the left and right quotes independently. If both ----qquuootteess and one of
the other options is set, ----llqquuoottee or ----rrqquuoottee overrides ----qquuootteess.
--rr _v_e_r_s_i_o_n, ----rreelleeaassee=_v_e_r_s_i_o_n
Set the centered footer for the ".TH" macro to _v_e_r_s_i_o_n. By default,
this is set to the version of Perl you run ppoodd22mmaann under. Setting
this to the empty string will cause some *roff implementations to use
the system default value.
Note that some system "an" macro sets assume that the centered footer
will be a modification date and will prepend something like "Last
modified: ". If this is the case for your target system, you may
want to set ----rreelleeaassee to the last modified date and ----ddaattee to the
version number.
--ss _s_t_r_i_n_g, ----sseeccttiioonn=_s_t_r_i_n_g
Set the section for the ".TH" macro. The standard section numbering
convention is 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. There
is a lot of variation here, however; some systems (like Solaris) use
4 for file formats, 5 for miscellaneous information, and 7 for
devices. Still others use 1m instead of 8, or some mix of both.
About the only section numbers that are reliably consistent are 1, 2,
and 3.
By default, section 1 will be used unless the file ends in ".pm", in
which case section 3 will be selected.
----ssttddeerrrr
By default, ppoodd22mmaann dies if any errors are detected in the POD input.
If ----ssttddeerrrr is given and no ----eerrrroorrss flag is present, errors are sent
to standard error, but ppoodd22mmaann does not abort. This is equivalent to
"--errors=stderr" and is supported for backward compatibility.
--uu, ----uuttff88
This option allows ppoodd22mmaann to output literal UTF-8 characters. On
OpenBSD, it is enabled by default and can be disabled with ----nnoo--uuttff88,
in which case non-ASCII characters are converted either to *roff
escape sequences or to "X".
Be aware that, when using this option, the input encoding of your POD
source should be properly declared unless it's US-ASCII. Pod::Simple
will attempt to guess the encoding and may be successful if it's
Latin-1 or UTF-8, but it will warn, which by default results in a
ppoodd22mmaann failure. Use the "=encoding" command to declare the
encoding. See ppeerrllppoodd(1) for more information.
--vv, ----vveerrbboossee
Print out the name of each output file as it is being generated.
EEXXIITT SSTTAATTUUSS #
As long as all documents processed result in some output, even if that
output includes errata (a "POD ERRORS" section generated with
"--errors=pod"), ppoodd22mmaann will exit with status 0. If any of the
documents being processed do not result in an output document, ppoodd22mmaann
will exit with status 1. If there are syntax errors in a POD document
being processed and the error handling style is set to the default of
"die", ppoodd22mmaann will abort immediately with exit status 255.
DDIIAAGGNNOOSSTTIICCSS #
If ppoodd22mmaann fails with errors, see Pod::Man and Pod::Simple for
information about what those errors might mean.
EEXXAAMMPPLLEESS #
pod2man program > program.1
pod2man SomeModule.pm /usr/perl/man/man3/SomeModule.3
pod2man --section=7 note.pod > note.7
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 mmaann(7).
troff -man -rC1 -rD1 perl.1 perldata.1 perlsyn.1 ...
To get index entries on "STDERR", turn on the F register, as in:
troff -man -rF1 perl.1
The indexing merely outputs messages via ".tm" for each major page,
section, subsection, item, and any "X<>" directives. See Pod::Man for
more details.
