Emacs has a powerful undo system. Unlike the standard undo/redo system in
|
|
most software, it allows you to recover *any* past state of a buffer
|
|
(whereas the standard undo/redo system can lose past states as soon as you
|
|
redo). However, this power comes at a price: many people find Emacs' undo
|
|
system confusing and difficult to use, spawning a number of packages that
|
|
replace it with the less powerful but more intuitive undo/redo system.
|
|
|
|
Both the loss of data with standard undo/redo, and the confusion of Emacs'
|
|
undo, stem from trying to treat undo history as a linear sequence of
|
|
changes. It's not. The `undo-tree-mode' provided by this package replaces
|
|
Emacs' undo system with a system that treats undo history as what it is: a
|
|
branching tree of changes. This simple idea allows the more intuitive
|
|
behaviour of the standard undo/redo system to be combined with the power of
|
|
never losing any history. An added side bonus is that undo history can in
|
|
some cases be stored more efficiently, allowing more changes to accumulate
|
|
before Emacs starts discarding history.
|
|
|
|
The only downside to this more advanced yet simpler undo system is that it
|
|
was inspired by Vim. But, after all, most successful religions steal the
|
|
best ideas from their competitors!
