DESCRIPTION
pod2man is a wrapper script around the Pod::Man module, using it to
generate *roff input from POD source. The resulting *roff code is
suitable for display on a terminal using nroff(1), normally via man(1),
or printing using troff(1).
By default (on non-EBCDIC systems), pod2man outputs UTF-8 manual pages.
Its output should work with the man program on systems that use groff
(most Linux distributions) or mandoc (most BSD variants), but may result
in mangled output on older UNIX systems. To choose a different,
possibly more backward-compatible output mangling on such systems, use
"--encoding=roff" (the default in earlier Pod::Man versions). See the
--encoding option and "ENCODING" in Pod::Man for more details.
input is the file to read for POD source (the POD can be embedded in
code). If input isn't given, it defaults to "STDIN". output, if given,
is the file to which to write the formatted output. If output isn't
given, the formatted output is written to "STDOUT". Several POD files
can be processed in the same pod2man invocation (saving module load and
compile times) by providing multiple pairs of input and output files on
the command line.
--section, --release, --center, --date, and --official can be used to
set the headers and footers to use. If not given, Pod::Man will assume
various defaults. See below for details.
OPTIONS
Each option is annotated with the version of podlators in which that
option was added with its current meaning.
-c string, --center=string
[1.00] Sets the centered page header for the ".TH" macro to string.
The default is "User Contributed Perl Documentation", but also see
--official below.
-d string, --date=string
[4.00] Set the left-hand footer string for the ".TH" macro to
string. By default, the first of POD_MAN_DATE, SOURCE_DATE_EPOCH,
the modification date of the input file, or the current date (if
input comes from "STDIN") will be used, and the date will be in UTC.
See "CLASS METHODS" in Pod::Man for more details.
-e encoding, --encoding=encoding
[5.00] Specifies the encoding of the output. encoding must be an
encoding recognized by the Encode module (see Encode::Supported).
The default on non-EBCDIC systems is UTF-8.
If the output contains characters that cannot be represented in this
encoding, that is an error that will be reported as configured by
the --errors option. If error handling is other than "die", the
unrepresentable character will be replaced with the Encode
substitution character (normally "?").
If the "encoding" option is set to the special value "groff" (the
default on EBCDIC systems), or if the Encode module is not available
and the encoding is set to anything other than "roff" (see below),
Pod::Man will translate all non-ASCII characters to "\[uNNNN]"
Unicode escapes. These are not traditionally part of the *roff
language, but are supported by groff and mandoc and thus by the
majority of manual page processors in use today.
If encoding is set to the special value "roff", pod2man will do its
historic transformation of (some) ISO 8859-1 characters into *roff
escapes that may be adequate in troff and may be readable (if ugly)
in nroff. This was the default behavior of versions of pod2man
before 5.00. With this encoding, all other non-ASCII characters
will be replaced with "X". It may be required for very old troff
and nroff implementations that do not support UTF-8, but its
representation of any non-ASCII character is very poor and often
specific to European languages. Its use is discouraged.
WARNING: The input encoding of the POD source is independent from
the output encoding, and setting this option does not affect the
interpretation of the POD input. Unless your POD source is US-
ASCII, its encoding should be declared with the "=encoding" command
in the source. If this is not done, Pod::Simple will will attempt
to guess the encoding and may be successful if it's Latin-1 or
UTF-8, but it will produce warnings. See perlpod(1) for more
information.
--errors=style
[2.5.0] 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".
--fixed=font
[1.0] The fixed-width font to use for verbatim text and code.
Defaults to "CW". Some systems may want "CR" instead. Only matters
for troff output.
--fixedbold=font
[1.0] Bold version of the fixed-width font. Defaults to "CB". Only
matters for troff output.
--fixeditalic=font
[1.0] Italic version of the fixed-width font (something of a
misnomer, since most fixed-width fonts only have an oblique version,
not an italic version). Defaults to "CI". Only matters for troff
output.
--fixedbolditalic=font
[1.0] Bold italic (in theory, probably oblique in practice) 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 troff output.
--guesswork=rule[,rule...]
[5.00] By default, pod2man applies some default formatting rules
based on guesswork and regular expressions that are intended to make
writing Perl documentation easier and require less explicit markup.
These rules may not always be appropriate, particularly for
documentation that isn't about Perl. This option allows turning all
or some of it off.
The special rule "all" enables all guesswork. This is also the
default for backward compatibility reasons. The special rule "none"
disables all guesswork. Otherwise, the value of this option should
be a comma-separated list of one or more of the following keywords:
functions
Convert function references like foo() to bold even if they have
no markup. The function name accepts valid Perl characters for
function names (including ":"), and the trailing parentheses
must be present and empty.
manref
Make the first part (before the parentheses) of man page
references like foo(1) bold even if they have no markup. The
section must be a single number optionally followed by lowercase
letters.
quoting
If no guesswork is enabled, any text enclosed in C<> is
surrounded by double quotes in nroff (terminal) output unless
the contents are already quoted. When this guesswork is
enabled, quote marks will also be suppressed for Perl variables,
function names, function calls, numbers, and hex constants.
variables
Convert Perl variable names to a fixed-width font even if they
have no markup. This transformation will only be apparent in
troff output, or some other output format (unlike nroff terminal
output) that supports fixed-width fonts.
Any unknown guesswork name is silently ignored (for potential future
compatibility), so be careful about spelling.
-h, --help
[1.00] Print out usage information.
-l, --lax
[1.00] No longer used. pod2man used to check its input for validity
as a manual page, but this should now be done by podchecker(1)
instead. Accepted for backward compatibility; this option no longer
does anything.
--language=language
[5.00] Add commands telling groff that the input file is in the
given language. The value of this setting must be a language
abbreviation for which groff provides supplemental configuration,
such as "ja" (for Japanese) or "zh" (for Chinese).
This adds:
.mso <language>.tmac
.hla <language>
to the start of the file, which configure correct line breaking for
the specified language. Without these commands, groff may not know
how to add proper line breaks for Chinese and Japanese text if the
man page is installed into the normal man page directory, such as
/usr/share/man.
On many systems, this will be done automatically if the man page is
installed into a language-specific man page directory, such as
/usr/share/man/zh_CN. In that case, this option is not required.
Unfortunately, the commands added with this option are specific to
groff and will not work with other troff and nroff implementations.
--lquote=quote
--rquote=quote
[4.08] Sets the quote marks used to surround C<> text. --lquote
sets the left quote mark and --rquote 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 --quotes option, which can be used to set both quotes
at once. If both --quotes and one of the other options is set,
--lquote or --rquote overrides --quotes.
-n name, --name=name
[4.08] Set the name of the manual page for the ".TH" macro to name.
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 manual pages is for the title to be in all-
uppercase, even if the command isn't. (Perl modules traditionally
use mixed case for the manual page title, however.)
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.
--nourls
[2.5.0] 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.
-o, --official
[1.00] Set the default header to indicate that this page is part of
the standard Perl release, if --center is not also given.
-q quotes, --quotes=quotes
[4.00] Sets the quote marks used to surround C<> text to quotes. If
quotes 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.
quotes 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 --lquote and --rquote options, which can be used to set
the left and right quotes independently. If both --quotes and one
of the other options is set, --lquote or --rquote overrides
--quotes.
-r version, --release=version
[1.00] Set the centered footer for the ".TH" macro to version. By
default, this is set to the version of Perl you run pod2man 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 --release to the last modified date and --date to
the version number.
-s string, --section=string
[1.00] 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.
--stderr
[2.1.3] By default, pod2man dies if any errors are detected in the
POD input. If --stderr is given and no --errors flag is present,
errors are sent to standard error, but pod2man does not abort. This
is equivalent to "--errors=stderr" and is supported for backward
compatibility.
-u, --utf8
[2.1.0] This option used to tell pod2man to produce UTF-8 output.
Since this is now the default as of version 5.00, it is ignored and
does nothing.
-v, --verbose
[1.11] Print out the name of each output file as it is being
generated.
EXIT STATUS
As long as all documents processed result in some output, even if that
output includes errata (a "POD ERRORS" section generated with
"--errors=pod"), pod2man will exit with status 0. If any of the
documents being processed do not result in an output document, pod2man
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", pod2man will abort immediately with exit status 255.
DIAGNOSTICS
If pod2man fails with errors, see Pod::Man and Pod::Simple for
information about what those errors might mean.
EXAMPLES
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 man(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.
