pod2text - Convert POD data to formatted ASCII text
pod2text [-aclostu] [--code] [--errors=style] [-i indent] [-q quotes] [--nourls] [--stderr] [-w width] [input [output ...]]
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
. output, if
given, is the file to which to write the formatted output. If output
isn't given, the formatted output is written to
. 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.
Use an alternate output format that, among other things, uses a different
heading style and marks
entries with a colon in the left margin.
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.
Format the output with ANSI color escape sequences. Using this option requires that Term::ANSIColor be installed on your system.
Set the error handling style.
die says to throw an exception on any
POD formatting error.
says to report errors on standard error,
but not to throw an exception.
says to include a POD ERRORS
section in the resulting documentation summarizing the errors.
ignores POD errors entirely, as much as possible.
The default is
Set the number of spaces to indent regular text, and the default indentation
blocks. Defaults to 4 spaces if this option isn't given.
Print out usage information and exit.
Print a blank line after a
heading. Normally, no blank line is
, although one is still printed after
because this is the expected formatting for manual pages; if you're
formatting arbitrary text documents, using this option is recommended.
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.
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:
- foo <http://example.com/>
This flag, if given, suppresses the URL when anchor text is given, so this
example would be formatted as just
. This can produce less
cluttered output in cases where the URLs are not particularly important.
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.
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
, in which case no
quote marks are added around C<> text.
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.
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
and is supported for backward
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.
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
command to declare the
encoding. See perlpod(1) for more information.
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
section generated with
), 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.
(F) -c or --color were given, but Term::ANSIColor could not be loaded.
(F) An unknown command line option was given.
In addition, other Getopt::Long error messages may result from invalid command-line options.
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.
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.
