NAME
Lingua::ZH::Wrap - Wrap Chinese text
VERSION
This document describes version 0.03 of Lingua::ZH::Wrap, released July 25, 2004.
SYNOPSIS
Example 1
use Lingua::ZH::Wrap;
$initial_tab = "\t"; # Tab before first line
$subsequent_tab = ""; # All other lines flush left
print wrap( $initial_tab, $subsequent_tab, @lines );Example 2
use Lingua::ZH::Wrap qw(wrap $columns $overflow);
$columns = 75; # Change columns
$overflow = 1; # Chinese char may occupy 76th col
print wrap( '', '', @lines );DESCRIPTION
Lingua::ZH::Wrap::wrap() is a very simple paragraph formatter. It formats a single paragraph at a time by breaking lines at Chinese character boundries.
Indentation is controlled for the first line ($initial_tab) and all subsequent lines ($subsequent_tab) independently. Please note: $initial_tab and $subsequent_tab are the literal strings that will be used: it is unlikely you would want to pass in a number.
OVERRIDES
Lingua::ZH::Wrap::wrap() has a number of variables that control its behavior.
Lines are wrapped at $Lingua::ZH::Wrap::columns columns; if a Chinese character just extends columns by one byte, it will be wrapped into the next line, unless $Lingua::ZH::Wrap::overflow is set to a true value.
CAVEATS
The algorithm doesn't care about breaking non-Chinese words. Also, if you pass in strings encoded unicode, it will currently first decode into Big5, do the conversion, then convert back.
Patches are, of course, very welcome; in particular, I'd like to use Lingua::ZH::TaBE to avoid beginning-of-line punctuations, as well as employing other semantic-sensitive formatting techniques.
