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.

Difftastic, a structural diff tool that understands syntax
Semantic Diff is probably the closest for now, although I don't think it uses tree-sitter.

My programming language aware diff for VS Code and GitHub now supports Rust
I am working on SemanticDiff, a programming language aware diff that hides style-only changes, detects moved code and refactorings. I just added support for Rust and would like to know what you think!

Prettier $20k Bounty was Claimed
If you're looking for a VS Code extension or a GitHub app, check out https://semanticdiff.com/. I'm a co-founder of this project.
If you prefer a CLI tool, check out https://github.com/Wilfred/difftastic. It supports more languages, but doesn't recognize when code has been replaced by an equivalent version ("invariances"). So it will show some changes (e.g. replacing a character in a string with an escape sequence) even though they are technically equivalent.

Large pull requests slow down development
There are some tools that can separate actual code changes from reformatting changes. I am working on https://semanticdiff.com, a VS Code Extension / GitHub App that can help you with this. There is also difftastic if you prefer a CLI based solution. It supports more languages but can detect fewer types of reformatting changes.

Pijul: Version-Control Post-Git • Goto 2023
I'm not familiar with Pijul, and haven't finished watching this presentation, but IME the problems with modern version control tools is that they still rely on comparing lines of plain text, something we've been doing for decades. Merge conflicts are an issue because our tools are agnostic about the actual content they're tracking.
Instead, the tools should be smarter and work on the level of functions, classes, packages, sentences, paragraphs, or whatever primitive makes sense for the project and file that is being changed. In the case of code bases, they need to be aware of the language and the AST of the program. For binary files, they need to be aware of the file format and its binary structure. This would allow them to show actually meaningful diffs, and minimize the chances of conflicts, and of producing a corrupt file after an automatic merge.
There has been some research in this area, and there are a few semantic diffing tools[1,2,3], but I'm not aware of this being widely used in any VCS.
Nowadays, with all the machine learning advances, the ideal VCS should also use ML to understand the change at a deeper level, and maybe even suggest improvements. If AI can write code for me, it could surely understand what I'm trying to do, and help me so that version control is entirely hands-free, instead of having to fight with it, and be constantly aware of it, as I have to do now.
I just finished watching the presentation, and Pijul seems like an iterative improvement over Git. Nothing jumped out at me like a killer feature that would make me want to give it a try. It might be because the author focuses too much on technical details, instead of taking a step back and rethinking what a modern VCS tool should look like today.

I added Go support to my VS Code extension for programming language aware diffs
You mean copying chunks from one file/side to the other? If that is the case, you might want to subscribe to this issue that was opened a few days ago. Since the extension does not work on a line-by-line level, it is a bit more difficult than for normal diffs. For example, what should happen if the formatting differs between both files. Should SemanticDiff copy it over as well or try to merge the changes? I will try to post an update on/in this issue soon and maybe have a discussion about the expected behavior.

Ask HN: Can we do better than Git for version control?
Yes, I think that we can do better than plain text as the source of truth, and thus git would probably need to change.
There's work around a bunch of languages that are not based on text, some have their own editor or a tool to manage a canonical representation in text for you that would make them friendlier to git.

I can't wait fast enough for these ideas to reshape how we deal with programs and build stuff.

Is Haskell gaining or losing popularity?
Haskell seems to be pretty big. For example in this list of projects it appears to be the second most popular language (after TypeScript) :)

Emacs Is Not Enough
It would be interesting to have such a general project go somewhere.
While in principle structural editing sounds like an incredible advance, there are 'good enough' advantages to plain-text tools that make it a much more practical solution. The other issue is of course integration with existing tooling, which you either skip entirely or compromise on the design.
What I feel is missing, between the description of "old, bad state of things" and "utopian vision" is a review of some of the projects that already tried to achieve this ideal state. It turns out there are a number of them, and most of them failed to achieve any traction or impact [0].
The rants are very long, so I skimmed quickly the one about git; I understand the complaints, although git is only bringing me joy and no pain --interactive rebase, absorb and a few aliases made it a breeze. But in a similar fashion there are projects trying to solve its fundamental issues, like pijul(.org); what are they missing?

Some good ones pops up in Projectional Programming [1] once in a while. The pinned thread links to the structure-editors github list [2] too.
