vundo VS emacs-undo-fu

vundo is a simpler implementation: it reuses Emacs's tree and just implements the visualisation part.

undo-tree is a reimplementation of Emacs's tree based undo, that supports a visualization.

Actually I put together vundo diff functionality which I use everyday; it's very simple so you can easily stick in your .emacs. Or perhaps will get added to vundo (maybe with a special color for the "diff-from" circle, or the ability to set a "from" and "to" for diffing across a few undos) . It's "on demand" rather than automatic, but I actually find it easier to get a diff buffer where I want it, then leave it as I move around the tree. Very happy with vundo.

And if you want a graphical undo without the large underlying data structure, give vundo a try. It just re-uses the same undo data structure emacs already keeps.

If you still want undo visualization, there's vundo that gives you a tree display of the state of the built-in undo: https://github.com/casouri/vundo

Is there anything like vundo for winner-mode? Or is any body have a winner-mode configuration that would behave like vundo?

Take a look at vundo:

vundo: Visualize the undo tree.

You could try vundo

I switched from undo-tree to vundo and am favorably impressed.

Submitted a PR to simplify that.

Try undo-fu, it's a thin wrapper on emacs built-in undo/redo but doesn't have this limitation.

Try undo-fu it was written to address exactly this problem.

Emacs has a good built-in undo function. And that one can be beefed up further with undo-tree --- which I used for some years --- or undo-fo --- which I use now ---.

I switched back from undo-tree to undo-fu, which re-uses the emacs undo-system instead of replacing it and makes it more intuitive to use while still preserving the full undo history. I sometimes miss the nice visualizations such as the tree and I didn't even know (or remember) the diff, but in 99% of cases I just need simple undo and most of the time I have git anyway to save intermediate states of my files.

There are packages that were written to add an explicit redo command, such as Undo Fu (https://gitlab.com/ideasman42/emacs-undo-fu) and Undo Tree (https://www.dr-qubit.org/undo-tree.html). Again, these packages are not needed in Emacs 28. That variable you found tells Evil which feature/package you want to use for an explicit redo command.

Had so many problems with this (once a month/week) and lost work... that I gave up and wrote undo-fu and undo-fu-session.

Did you try undo-fu?
