|center||Sets the centered page header for the .TH macro. The default, if this option is not specified, is User Contributed Perl Documentation.|
|date||Sets the left-hand footer for the .TH macro. If this option is not set, the contents of the environment variable POD_MAN_DATE, if set, will be used. Failing that, the value of SOURCE_DATE_EPOCH, the modification date of the input file, or the current time if stat() cant find that file (which will be the case if the input is from STDIN) will be used. If obtained from the file modification date or the current time, the date will be formatted as YYYY-MM-DD and will be based on UTC (so that the output will be reproducible regardless of local time zone).|
How to report errors. 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 pod.
|fixed||The fixed-width font to use for verbatim text and code. Defaults to CW. Some systems may want CR instead. Only matters for <B>troffB> output.|
|fixedbold||Bold version of the fixed-width font. Defaults to CB. Only matters for <B>troffB> output.|
|fixeditalic||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 <B>troffB> output.|
|fixedbolditalic||Bold italic (probably actually oblique) version of the fixed-width font. Pod::Man doesnt assume you have this, and defaults to CB. Some systems (such as Solaris) have this font available as CX. Only matters for <B>troffB> output.|
Set the name of the manual page for the .TH macro. 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.
If generating a manual page from standard input, this option is required, since theres otherwise no way for Pod::Man to know what to use for the manual page name.
Normally, L<> formatting codes with a URL but anchor text are formatted
to show both the anchor text and the URL. In other words:
is formatted as:
This option, if set to a true value, 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.
Sets the quote marks used to surround C<> text. If the value 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.
This 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).
Set the centered footer for the .TH macro. By default, this is set to
the version of Perl you run Pod::Man under. Setting this to the empty
string will cause some *roff implementations to use the system default
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.
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||Send error messages about invalid POD to standard error instead of appending a POD ERRORS section to the generated *roff output. This is equivalent to setting errors to stderr if errors is not already set. It is supported for backward compatibility.|
By default, Pod::Man produces the most conservative possible *roff output
to try to ensure that it will work with as many different *roff
implementations as possible. Many *roff implementations cannot handle
non-ASCII characters, so this means all non-ASCII characters are converted
either to a *roff escape sequence that tries to create a properly accented
character (at least for troff output) or to X.
If this option is set, Pod::Man will instead output UTF-8. If your *roff implementation can handle it, this is the best output format to use and avoids corruption of documents containing non-ASCII characters. However, be warned that *roff source with literal UTF-8 characters is not supported by many implementations and may even result in segfaults and other bad behavior.
Be aware that, when using this option, the input encoding of your POD source should be properly declared unless its US-ASCII. Pod::Simple will attempt to guess the encoding and may be successful if its Latin-1 or UTF-8, but it will produce warnings. Use the =encoding command to declare the encoding. See perlpod(1) for more information.
The standard Pod::Simple method parse_from_file() takes up to two arguments, the first being the input file to read POD from and the second being the file to write the formatted output to.
You can also call parse_lines() to parse an array of lines or parse_string_document() to parse a document already in memory. As with parse_file(), parse_lines() and parse_string_document() default to sending their output to STDOUT unless changed with the output_fh() method.
To put the output from any parse method into a string instead of a file handle, call the output_string() method instead of output_fh().
See Pod::Simple for more specific details on the methods available to all derived parsers.
roff font should be 1 or 2 chars, not %s (F) You specified a *roff font (using fixed, fixedbold, etc.) that wasnt either one or two characters. Pod::Man doesnt support *roff fonts longer than two characters, although some *roff extensions do (the canonical versions of <B>nroffB> and <B>troffB> dont either). Invalid errors setting %s (F) The errors parameter to the constructor was set to an unknown value. Invalid quote specification %s (F) The quote specification given (the quotes option to the constructor) was invalid. A quote specification must be either one character long or an even number (greater than one) characters long. POD document had syntax errors (F) The POD document being formatted had syntax errors and the errors option was set to die.
PERL_CORE If set and Encode is not available, silently fall back to non-UTF-8 mode without complaining to standard error. This environment variable is set during Perl core builds, which build Encode after podlators. Encode is expected to not (yet) be available in that case. POD_MAN_DATE If set, this will be used as the value of the left-hand footer unless the date option is explicitly set, overriding the timestamp of the input file or the current time. This is primarily useful to ensure reproducible builds of the same output file given the same source and Pod::Man version, even when file timestamps may not be consistent. SOURCE_DATE_EPOCH If set, and POD_MAN_DATE and the date options are not set, this will be used as the modification time of the source file, overriding the timestamp of the input file or the current time. It should be set to the desired time in seconds since UNIX epoch. This is primarily useful to ensure reproducible builds of the same output file given the same source and Pod::Man version, even when file timestamps may not be consistent. See <https://reproducible-builds.org/specs/source-date-epoch/> for the full specification.
(Arguably, according to the specification, this variable should be used only if the timestamp of the input file is not available and Pod::Man uses the current time. However, for reproducible builds in Debian, results were more reliable if this variable overrode the timestamp of the input file.)
Encoding handling assumes that PerlIO is available and does not work properly if it isnt. The utf8 option is therefore not supported unless Perl is built with PerlIO support.
There is currently no way to turn off the guesswork that tries to format unmarked text appropriately, and sometimes it isnt wanted (particularly when using POD to document something other than Perl). Most of the work toward fixing this has now been done, however, and all thats still needed is a user interface.
The NAME section should be recognized specially and index entries emitted for everything in that section. This would have to be deferred until the next section, since extraneous things in NAME tends to confuse various man page processors. Currently, no index entries are emitted for anything in NAME.
Pod::Man doesnt handle font names longer than two characters. Neither do most <B>troffB> implementations, but GNU troff does as an extension. It would be nice to support as an option for those who want to use it.
The preamble added to each output file is rather verbose, and most of it is only necessary in the presence of non-ASCII characters. It would ideally be nice if all of those definitions were only output if needed, perhaps on the fly as the characters are used.
Pod::Man is excessively slow.
If Pod::Man is given the utf8 option, the encoding of its output file handle will be forced to UTF-8 if possible, overriding any existing encoding. This will be done even if the file handle is not created by Pod::Man and was passed in from outside. This maintains consistency regardless of PERL_UNICODE and other settings.
When and whether to use small caps is somewhat tricky, and Pod::Man doesnt necessarily get it right.
Converting neutral double quotes to properly matched double quotes doesnt work unless there are no formatting codes between the quote marks. This only matters for troff output.
