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! +</longdescription> +<stabilize-allarches/> +</pkgmetadata> |
