Pod::Text::Overstrike3perl

Usage

    use Pod::Text::Overstrike;
    my $parser = Pod::Text::Overstrike->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');

Overview

Pod::Text::Overstrike is a simple subclass of Pod::Text that highlights output text using overstrike sequences, in a manner similar to nroff. Characters in bold text are overstruck (character, backspace, character) and characters in underlined text are converted to overstruck underscores (underscore, backspace, character). This format was originally designed for hard-copy terminals and/or line printers, yet is readable on soft-copy (CRT) terminals.

Overstruck text is best viewed by page-at-a-time programs that take advantage of the terminal's stand-out and underline capabilities, such as the less program on Unix.

Apart from the overstrike, it in all ways functions like Pod::Text. See Pod::Text for details and available options.

Compatibility

Pod::Text::Overstrike 1.01 (based on Pod::Parser) was the first version of this module included with Perl, in Perl 5.6.1.

The current API based on Pod::Simple was added in Pod::Text::Overstrike 2.00, included in Perl 5.9.3.

Several problems with wrapping and line length were fixed as recently as Pod::Text::Overstrike 6.0.0.

This module inherits its API and most behavior from Pod::Text, so the details in "COMPATIBILITY" in Pod::Text also apply. Pod::Text and Pod::Text::Overstrike have had the same module version since 4.00, included in Perl 5.23.7. (They unfortunately diverge in confusing ways prior to that.)

Caveats

Line wrapping is done only at ASCII spaces and tabs, rather than using a correct Unicode-aware line wrapping algorithm.
