Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

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.

* 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?

help understanding how to do undo/redo.
Take a look at 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.

What are the small reasons to try Emacs?
Some killer features in Emacs, which I would recommend checking out, is imenu and movement by s-expression (functions like forward-sexp). These are built into Emacs and make navigating across or inside blocks of code very easy. I have also seen that lispy, which is usually used for Lisp code also supports Python. Again I can't speak to any specifics about how well these things work for Python devs.

Any way to make lispy format works automatically?
While writing other programming languages with LSP, it formats the buffer once I hit save. Is there any way to make https://github.com/abo-abo/lispy do some equivalent behaviour?

Emacs/Slime equivalent of some Cider features?
I don't know cider, but...I found lispy mode a revelation in making the easy, easier.

Why is it hard to get started with elisp in emacs
The level of interactivity in your emacs determines how easy trying emacs-lisp becomes. I suggest checking out https://github.com/abo-abo/lispy, it makes it easy to look up documentation (C-c 1 I believe) and evaluate S-expressions on the fly (keybinding is e). Also C-h f, C-h k, C-h v are always very helpful. Also check out helpful (the package), selectrum, marginalia, prescient, etc.

Tree Sitter and the Complications of Parsing Languages
Emacs seems to attract quite a lot of people who want structural code editing. We now have * paredit * smartparens * evil-cleverparens * lispy * symex * combobulate (more?)

The State of Structural Editing in Emacs?
Obviously, we have packages like Paredit and Lispy, recently we got SymEx, but these are all for the Lisp family of languages, where syntactic redundancy is very high because of the homoiconicity.
What are some alternatives?
