vundo VS company-mode

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.

* vundo LOC: 1350. https://github.com/casouri/vundo/blob/master/vundo.el

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.

I'm curious to know what `company` does differently here than `corfu`. As a longtime user I couldn't be happier.

https://company-mode.github.io/

they wrote the first word and auto-completed the rest

For me, it's http://company-mode.github.io and maybe a touch of all-the-icons..

I'm not sure if I did anything special to enable it, but I'm pretty sure company-mode does this

When I started using Emacs I was following the setup outlined by System Crafters, which I still think is a really good introduction. But, over the last few months I've started to replace packages with more "minimalist" or "stripped down" packages. I've switched from Ivy and Counsel to Vertico and Consult, and recently I switched from company to corfu for auto-completion.

As for the Emacs configuration, you should only need a few lines of code, in order to get them up and running, if you are planning to keep your setup as close to vanilla as possible. If you are interested, you could additionally install a completion framework like company-mode to help you out.

As for auto-completion, there's a few different variants that people use. Auto-complete being one of them, but an alternative you might want to try is http://company-mode.github.io/

For the company-mode see Frontends.

Company is a classic, though corfu and cape, also by Daniel Mendler is really excellent.
