Requirements

• Vim 7.3+
• Python support for Vim
• Python 2.4+

Installation

Use Pathogen. Don't use pathogen? Start.

hg clone http://bitbucket.org/sjl/gundo.vim ~/.vim/bundle/gundo

There's a git mirror if you prefer:

git clone http://github.com/sjl/gundo.vim.git ~/.vim/bundle/gundo

Add a mapping to your ~/.vimrc (change the key to suit your taste):

nnoremap <F5> :GundoToggle<CR>

Usage

Run :help gundo for the full docs. Here's the in-a-nutshell version.

When you're editing a file you can bring up the undo graph for that file with <F5> (or whatever key you mapped it to).

Press <F5> again to close the undo graph and return to your file.

Use j and k to move up and down the graph. The preview pane will update with a diff of the change made by the undo state you're currently on.

Press return to revert the file's contents to that undo state and return to the file.
