#24 closed defect (fixed)

No "undo/redo" support

Reported by: gb Owned by: jaj@…
Priority: major Milestone:
Component: IDE Version: 1.1
Keywords: Cc:


Of the three general schemes for implementing undo/redo that I can think of - namely:

  1. Use the Cocoa text system's built-in support
  1. Use an NSUndoManager to track changes to the buffer/textstorage
  1. Do it all at the lisp level

I think that either (2) or (3) would be the most attractive.

This is partially done. Need to implement grouping, redo, and make listener output not be undoable.
