It uses no +special formatting controls or codes whatsoever, and its output is therefore +suitable for nearly any device. + +As a derived class from Pod::Simple, Pod::Text supports the same methods and +interfaces. See L<Pod::Simple> for all the details; briefly, one creates a +new parser with C<< Pod::Text->new() >> and then normally calls parse_file(). + +new() can take options, in the form of key/value pairs, that control the +behavior of the parser. The currently recognized options are: + +=over 4 + +=item alt + +If set to a true value, selects an alternate output format that, among other +things, uses a different heading style and marks C<=item> entries with a +colon in the left margin. Defaults to false. + +=item code + +If set to a true value, the non-POD parts of the input file will be included +in the output. Useful for viewing code documented with POD blocks with the +POD rendered and the code left intact. + +=item indent + +The number of spaces to indent regular text, and the default indentation for +C<=over> blocks. Defaults to 4. + +=item loose + +If set to a true value, a blank line is printed after a C<=head1> heading. +If set to false (the default), no blank line is printed after C<=head1>, +although one is still printed after C<=head2>. This is the default because +it's the expected formatting for manual pages; if you're formatting +arbitrary text documents, setting this to true may result in more pleasing +output. + +=item margin + +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 the I<indent> option. To set the right +margin, see the I<width> option. + +=item quotes + +Sets the quote marks used to surround CE<lt>> text. If the value is a +single character, it is used as both the left and right quote; if it is two +characters, the first character is used as the left quote and the second as +the right quoted; and if it is four characters, the first two are used as +the left quote and the second two as the right quote. + +This may also be set to the special value C<none>, in which case no quote +marks are added around CE<lt>> text. + +=item sentence + +If set to a true value, Pod::Text will assume that each sentence ends in two +spaces, and will try to preserve that spacing. If set to false, all +consecutive whitespace in non-verbatim paragraphs is compressed into a +single space. Defaults to true. + +=item width + +The column at which to wrap text on the right-hand side. Defaults to 76. + +=back + +The standard Pod::Simple method parse_file() takes one argument, the file or +file handle to read from, and writes output to standard output unless that +has been changed with the output_fh() method. See L<Pod::Simple> for the +specific details and for other alternative interfaces. + +=head1 DIAGNOSTICS + +=over 4 + +=item Bizarre space in item + +=item Item called without tag + +(W) Something has gone wrong in internal C<=item> processing. These +messages indicate a bug in Pod::Text; you should never see them. + +=item Can't open %s for reading: %s + +(F) Pod::Text was invoked via the compatibility mode pod2text() interface +and the input file it was given could not be opened. + +=item Invalid quote specification "%s" + +(F) The quote specification given (the quotes option to the constructor) was +invalid. A quote specification must be one, two, or four characters long. + +=back + +=head1 NOTES + +This is a replacement for an earlier Pod::Text module written by Tom +Christiansen. It has a revamped interface, since it now uses Pod::Simple, +but an interface roughly compatible with the old Pod::Text::pod2text() +function is still available. Please change to the new calling convention, +though. + +The original Pod::Text contained code to do formatting via termcap +sequences, although it wasn't turned on by default and it was problematic to +get it to work at all. This rewrite doesn't even try to do that, but a +subclass of it does. Look for L<Pod::Text::Termcap>. + +=head1 SEE ALSO + +L<Pod::Simple>, L<Pod::Text::Termcap>, L<pod2text(1)> + +The current version of this module is always available from its web site at +L<http://www.eyrie.org/~eagle/software/podlators/>. It is also part of the +Perl core distribution as of 5.6.0. + +=head1 AUTHOR + +Russ Allbery <rra@stanford.edu>, based I<very> heavily on the original +Pod::Text by Tom Christiansen <tchrist@mox.perl.com> and its conversion to +Pod::Parser by Brad Appleton <bradapp@enteract.com>. Sean Burke's initial +conversion of Pod::Man to use Pod::Simple provided much-needed guidance on +how to use Pod::Simple. + +=head1 COPYRIGHT AND LICENSE + +Copyright 1999, 2000, 2001, 2002, 2004, 2006 Russ Allbery <rra@stanford.edu>. + +This program is free software; you may redistribute it and/or modify it +under the same terms as Perl itself. + +=cut |
