pod2text - Convert POD data to formatted ASCII text
pod2text [-aclostu] [--code] [--errors=style]
[-i indent]
[-q quotes] [--nourls] [--stderr]
[-w width]
[input [output ...]]
pod2text -h
pod2text is a front-end for Pod::Text and its subclasses. It uses them to
generate formatted ASCII text from POD source. It can optionally use either
termcap sequences or ANSI color escape sequences to format the text.
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 pod2text invocation (saving module load and
compile times) by providing multiple pairs of input and output
files on the command line.
- -a, --alt
- Use an alternate output format that, among other things, uses a different
heading style and marks "=item" entries
with a colon in the left margin.
- --code
- Include any non-POD text from the input file in the output as well. Useful
for viewing code documented with POD blocks with the POD rendered and the
code left intact.
- -c, --color
- Format the output with ANSI color escape sequences. Using this option
requires that Term::ANSIColor be installed on your system.
- --errors=style
- 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".
- -i indent, --indent=indent
- Set the number of spaces to indent regular text, and the default
indentation for "=over" blocks. Defaults
to 4 spaces if this option isn't given.
- -h, --help
- Print out usage information and exit.
- -l, --loose
- Print a blank line after a "=head1"
heading. Normally, no blank line is printed after
"=head1", although one is still printed
after "=head2", because this is the
expected formatting for manual pages; if you're formatting arbitrary text
documents, using this option is recommended.
- -m width, --left-margin=width,
--margin=width
- The width of the left margin in spaces. Defaults to 0. This is the margin
for all text, including headings, not the amount by which regular text is
indented; for the latter, see -i option.
- --nourls
- 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, --overstrike
- Format the output with overstrike printing. Bold text is rendered as
character, backspace, character. Italics and file names are rendered as
underscore, backspace, character. Many pagers, such as less, know
how to convert this to bold or underlined text.
- -q quotes, --quotes=quotes
- 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.
- -s, --sentence
- Assume each sentence ends with two spaces and try to preserve that
spacing. Without this option, all consecutive whitespace in non-verbatim
paragraphs is compressed into a single space.
- --stderr
- By default, pod2text 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 pod2text does not abort.
This is equivalent to "--errors=stderr"
and is supported for backward compatibility.
- -t, --termcap
- Try to determine the width of the screen and the bold and underline
sequences for the terminal from termcap, and use that information in
formatting the output. Output will be wrapped at two columns less than the
width of your terminal device. Using this option requires that your system
have a termcap file somewhere where Term::Cap can find it and requires
that your system support termios. With this option, the output of
pod2text will contain terminal control sequences for your current
terminal type.
- -u, --utf8
- By default, pod2text tries to use the same output encoding as its
input encoding (to be backward-compatible with older versions). This
option says to instead force the output encoding to UTF-8.
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
pod2text failure. Use the
"=encoding" command to declare the
encoding. See perlpod(1) for more information.
- -w, --width=width, -width
- The column at which to wrap text on the right-hand side. Defaults to 76,
unless -t is given, in which case it's two columns less than the
width of your terminal device.
As long as all documents processed result in some output, even if that output
includes errata (a "POD ERRORS" section
generated with "--errors=pod"),
pod2text will exit with status 0. If any of the documents being
processed do not result in an output document, pod2text 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", pod2text will abort
immediately with exit status 255.
If pod2text fails with errors, see Pod::Text and Pod::Simple for
information about what those errors might mean. Internally, it can also
produce the following diagnostics:
- -c (--color) requires Term::ANSIColor be installed
- (F) -c or --color were given, but Term::ANSIColor could not
be loaded.
- Unknown option: %s
- (F) An unknown command line option was given.
In addition, other Getopt::Long error messages may result from
invalid command-line options.
- COLUMNS
- If -t is given, pod2text will take the current width of your
screen from this environment variable, if available. It overrides terminal
width information in TERMCAP.
- TERMCAP
- If -t is given, pod2text will use the contents of this
environment variable if available to determine the correct formatting
sequences for your current terminal device.
