The Tk::TextVi module is a Tk::TextUndo widget that replaces InsertKeypress() to handle user input similar to vi. All other methods remain the same (and most code should be using $text->insert( ... ) rather than $text->InsertKeypress()). This only implements the text widget and key press logic; the status bar must be drawn by the application (see TextViDemo.pl for an example of this).
To use Tk::TextVi as a drop-in replacement for other text widgets, see Tk::EditorVi which encapsulates Tk::TextVi and the status bar into a composite widget. (This module is included in the Tk::TextVi distribution, but is not installed.)
Functions in Vi that require interaction with the system (such as reading or writing files) are not (currently) handled by this module (This is a feature since you probably don't want :quit to do exactly that). Instead a callback is provided so that the application using the Tk::TextVi widget may decide how to act on them.
The cursor in a Tk::Text widget is a mark placed between two characters. Vi's idea of a cursor is placed on a non-newline character or a blank line. Tk::TextVi treats the cursor as on (in the Vi-sense) the characters following the cursor (in the Tk::Text sense). This means that $ will place the cursor just before the final character on the line.
SYNOPSIS
use Tk::TextVi;
$textvi = $window->TextVi( -option => value, ... );
