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 It supports more languages, but doesn't recognize when code has been replaced by an equivalent version ("invariances").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.

Difftastic, a structural diff tool that understands syntax
Tree-sitter optimizes for performance (to use in editors), not for correctness. In fact even TS' core developers advocate for not bothering too much with correctness of grammars[1]. I imagine this constraint would be a deal-breaker for GitHub or anyone else in their position.

Shiki Syntax Highlighter
Is tree-sitter really slower than TextMate grammars? Some benchmarks indicate that this isn't really the case [1]. On the other hand, breaking parse trees is a real issue, because the error-recovery in tree-sitter is pretty rudimentary [2][3], but as you said, it's not an issue for Shiki.
Several TextMate grammars suffer from inaccuracy bugs, and issues of maintainability. Perhaps the biggest hindrance in the adoption of tree-sitter, is that the most popular editor, VSCode, still doesn't support it.

It seems that some BIG improvements of Treesitter on BIG FILEs have been merged into Nightly! (minutes ago!)
u/lewis6991 I think the biggest performance gain was made by tree-sitter itself: https://github.com/tree-sitter/tree-sitter/pull/2085

Looking for Tree-sitter query documentations and guides
I asked on the repo's discussions but responses are limited and not explanatory (I'm not shaming anyone here, discussions aren't a place for detailed how-tos and documentations anyway).

Will Treesitter ever be stable on big files?
The following discussion here. TS query cannot be incremental, that is why I regard it as design fault.

Detailed syntax highlighting
Hi, so I've recently decided to give Neovim yet another try, this time using some predefined plugins with kickstart.nvim, for syntax it uses tree-sitter.
What are some alternatives?
mergify - Merge git changes on commit at a time.
nvim-treesitter - Nvim Treesitter configurations and abstraction layer
git-machete - Probably the sharpest git repository organizer & rebase/merge workflow automation tool you've ever seen
Visual Studio Code - Visual Studio Code
vscode-settings - My VS Code settings and extensions
indent-blankline.nvim - Indent guides for Neovim
graphtage - A semantic diff utility and library for tree-like files such as JSON, JSON5, XML, HTML, YAML, and CSV.
doom-emacs - An Emacs framework for the stubborn martian hacker [Moved to: https://github.com/doomemacs/doomemacs]
difftastic - a structural diff that understands syntax 🟥🟩
language-server-protocol - Defines a common protocol for language servers.
git-stack - Stacked branch management for Git
coc-explorer - 📁 Explorer for coc.nvim
