old-fashioned-undo.el — Undo/Redo in very simple, and old fashioned way.

A NOTE ON NEWER VERSIONS OF EMACS (>= 28.1)

On Emacs versions 28.1 and later, you may no longer need this library, since the `undo-redo’ command provides similar results to what this library provides.

OVERVIEW

This library provides minor mode `old-fashioned-undo-mode’ which makes `undo’ and `redo’ command working in an old fashioned way.

The default `undo/redo’ commands provided by emacs records each `undo/redo’ operations on `buffer-undo-list’. This behavior may make undo/redo operations perfect, but I feel this behavior is too much verbose and little bit annoying.

The undo/redo command provided this library never records `undo/redo’ operation on `buffer-undo-list’ so that we can `undo/redo’ in intuitive way.

Additionally, while `old-fashioned-undo-mode’ is on, the number of pending `undo/redo’ operation will be displayed in the minibuffer when each `undo/redo’ command is executed.

INSTALLING

To install this library, save this file to a directory in your `load-path’ (you can view the current `load-path’ using “C-h v load-path RET” within Emacs), then add the following line to your .emacs startup file:

(require ‘old-fashioned-undo) (old-fashioned-undo-mode t)

USING

To toggle old-fashioned-undo feature, just type:

`M-x old-fashioned-undo-mode RET’

Key map Examples

(global-set-key [(control z)] ‘undo) (global-set-key [(control Z)] ‘redo)

KNOWN PROBLEMS

• Cursor position won’t be set properly after undo/redo when cua-mode is on.
