Text Editor Data Structures: Rethinking Undo
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.
* undo-tree LOC: 4700. https://gitlab.com/tsc25/undo-tree/-/blob/master/undo-tree.e...
* vundo LOC: 1350. https://github.com/casouri/vundo/blob/master/vundo.el

WTF is: "Re-entering top level after C stack overflow"?
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.

Significant performance issues, am I doing anything really stupid?
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.
-
Is there anything like “undo at this line?”
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

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

What's the best way to use undo-redo on emacs?
You could try vundo
-
What have you recently *removed* from your Emacs configuration?
I switched from undo-tree to vundo and am favorably impressed.
-
Vundo is great! (visual undo-tree for emacs-28)
Submitted a PR to simplify that.

Ask HN: Best way to experiment with text text editing?
To build on what others are saying about Emacs, if you start exploring the package ecosystem, you're going to see quite a lot of really interesting packages that are related to improving/experimenting with the UX of editing text. While I'm not endorsing anyone in particular, I think what this list does show is just how easy it is to do pretty much whatever you want in Emacs;
https://karthinks.com/software/avy-can-do-anything/
https://github.com/jyp/boon
https://github.com/clemera/objed
https://github.com/jmorag/kakoune.el
https://github.com/meow-edit/meow/
https://github.com/xahlee/xah-fly-keys
https://github.com/Kungsgeten/ryo-modal
https://github.com/emacsorphanage/god-mode
Emacs 29 also now has treesitter and LSP mode integration built-in, a compilation mode, a comint mode for REPLs, excellent file browsing packages (I use dired/dirvish), and a few other killer features.
Now, if what you truly dislike are "quirky editors", prepare yourself for a world of hurt because vanilla Emacs departs quite a bit from "modern" text editors. I struggled with this for a while, but eventually by buying into the paradigm, I now feel that when emacs try emulating "modern" IDE features like autocompletion, LSP, and DAP UI, I feel like it's a regression, not a progression. The point here is that you might have an "idea" of what good initial UX and lack of quirks would look like, but Emacs might change the way you think.

Why another modal editing package in Emacs?
This looks like an interesting and valiant attempt to build something that improves on everything that came before it, but I did find the documentation lacking in clarity.
I'm experimenting with this package right now instead:
https://github.com/clemera/objed
and will wire up the keyboard shortcuts using RYO package to roll my own modal state.

Effective and efficient text editing using Emacs (Alternative to Evil)
Wow. meow project looks similar to objed but with more features. These projects are inclined to modal editing but not being vim. Thank you for suggesting.
-
What is your favorite text-editing package / command?
I like the semi-modal editing package objed (short for textual object editor)
-
atp - an experimental package for fast and intuitive text editing
This reminds me of u/clemera's objed and of versor.

Moving from evil to mostly-emacs keybindings
There are other modal systems for emacs. You even can construct your own with https://github.com/mrkkrp/modalka and https://github.com/Kungsgeten/ryo-modal. I have done that, these packages were extremely easy to use. I had a lot of fun designing the modal regime of my dreams. There are https://github.com/LouisKottmann/emacs-baboon, https://github.com/xahlee/xah-fly-keys (and its various forks) and https://github.com/clemera/objed.

I forgot about objed! Which is another very interesting project.

Guide-article: A Lisp REPL as my main shell
I didn't fully get what your interactive piping solution is, but I found that objed has a command oddly unrelated to the rest of its codebase: objed-ipipe, which does what I imagined Howard's piper to do but more intuitively to me. Though it seems you can write piper commands out in lisp so it's probably a superset feature-wise, I just never got started learning it.
-
What key binding scheme do you use to handle parentheses?
Well laid out, I fully agree. I think there is still a lot of potential to combine these two approaches in a better way, Emacs knows about many structures already but I think it could be more convenient to act on those. I tried my hand on this with objed which aims to make it easier to act/navigate on certain units (on demand or semi automatically).
What are some alternatives?
