pod::text::color

Pod::Text::Color(3perl) 				 Perl Programmers Reference Guide				   Pod::Text::Color(3perl)

NAME

       Pod::Text::Color - Convert POD data to formatted color ASCII text

SYNOPSIS

	   use Pod::Text::Color;
	   my $parser = Pod::Text::Color->new (sentence => 0, width => 78);

	   # Read POD from STDIN and write to STDOUT.
	   $parser->parse_from_filehandle;

	   # Read POD from file.pod and write to file.txt.
	   $parser->parse_from_file ('file.pod', 'file.txt');

DESCRIPTION

       Pod::Text::Color is a simple subclass of Pod::Text that highlights output text using ANSI color escape sequences.  Apart from the color, it
       in all ways functions like Pod::Text.  See Pod::Text for details and available options.

       Term::ANSIColor is used to get colors and therefore must be installed to use this module.

BUGS

       This is just a basic proof of concept.  It should be seriously expanded to support configurable coloration via options passed to the
       constructor, and pod2text should be taught about those.

SEE ALSO

       Pod::Text, Pod::Simple

       The current version of this module is always available from its web site at <http://www.eyrie.org/~eagle/software/podlators/>.  It is also
       part of the Perl core distribution as of 5.6.0.
