Tk::DiffText 0.17

Tk::DiffText is a Perl/Tk composite widget for colorized diffs.

SYNOPSIS

use Tk::DiffText;

my $w = $mw->DiffText()->pack();

$w->diff($file0, $file1);

This module defines a composite widget that makes it simple to provide basic "diff" functionality to your Tk applications.

OPTIONS

-orient => horizontal|vertical
Controls the arrangement of the text panes. Defaults to vertical.
-gutter => 0|1
Hides and displays the line number gutter. Defaults to 1.
-gutterforeground => color
Sets the gutter foreground color.
-gutterbackground => color
Sets the gutter background color.
-diffcolors => {...}
Sets the colors used for highlighting diff results. The structure of the value hash is as follows:
{
add => [-fg => green ], # tag for additions
del => [-fg => red, -overstrike => 1], # tag for deletions
mod => [-fg => blue ], # tag for changes
pad => [-bg => #f0f0f0], # tag for blank line padding
}

For each of the tags you can specify any option that is valid for use in a ROText widget tag: -foreground, -background, -overstrike, etc.
-map => scaled|scrolled|none

Controls the display and type of difference map. Defaults to scaled.

The difference map will match its colors to those from -diffcolors by default. It uses the background color if specified, otherwise it uses the foreground color.
