The <a href="http://www.dr-qubit.org/undo-tree/undo-tree.el">Emacs undo-tree library</a> has a way to visualize the tree and move through it with your keyboard, which solves this problem.</p> <p>But now, thanks to Steve Losh, <a href="http://bitbucket.org/sjl/gundo.vim/src">Vim has an undo-tree visualizer too</a>. Delicious. Though it's still beta and promises to eat your babies, it seems to work pretty well. I think the diff view of the changes for the undo is a really good idea.</p> <p>Thus continues the eternal Vim/Emacs arms race.</p> <p><img src="/vim/vim-undo-tree.png" alt="Vim undo tree" title="" /></p>http://briancarper.net/blog/568/emacs-undo-treeshttp://briancarper.net/blog/568/emacs-undo-treesTue, 17 Aug 2010 14:06:33 -0700<p>I've said it before: <a href="/blog/361/emacs-undo-is-horrible">undo in Emacs is horrible</a>. On the other hand, <a href="http://stackoverflow.com/questions/1088864/how-is-vims-undo-tree-used">undo in Vim is awesome</a>.</p> <p>But this is true no longer. Now there are <strong><em><a href="http://www.dr-qubit.org/undo-tree/undo-tree.el">undo trees for Emacs!</a></em></strong> Yes, this news is so important I had to italicize and bold it. It's like Emacs has been punching me in the face for years, and today I got it to stop. I never thought I'd see the day.</p> <p>And it works great too. You can even view the tree visually and navigate it with the cursor keys, which is a step up on what Vim offers out of the box.</p> <p><img src="/emacs/emacs-undo-trees.png" alt="Emacs undo trees" title="" /></p> <p>In other news, Vim 7.3 is out and it now has <a href="https://groups.google.com/group/vim_announce/browse_thread/thread/66c02efd1523554b">persistent undo</a> across reloads. It's like an arms race, and gleeful hackers reap the benefits.</p>
