tree-sitter-langs VS tree-sitter

I just had a quick look at tree-sitter-langs to double check its TypeScript support. And seems to have a full set of highlight queries for it.

I use script/compile swift from 'tree-sitter-langs' to build the grammar on both M1 and x86 machines. But I was looking at that code yesterday and I actually can't figure out why it works to produce an arm64 dylib for me. There's no place where the target arch is being set. It's very odd.

However, there are no queries available for it to highlight csharp: https://github.com/emacs-tree-sitter/tree-sitter-langs/tree/388dcbbc237b2b1360e5b148e67b158eecede805/queries

I've forked tree-sitter-langs with https://github.com/kiennq/tree-sitter-langs that can be used to convert from the current emacs-tree-sitter syntax to the built-in treesit's syntax. Based on https://github.com/emacs-tree-sitter/tree-sitter-langs/pull/99.

Those grammars are collected in the tree-sitter-langs repo, or you can build them yourself. I assume they're not bundled with Emacs yet, even on the feature branch. I don't know how the Emacs tree-sitter branch expects them to be registered and associated with a language mode, though.

The "essentially" qualifier is just because of the tree-sitter issue I was mentioning earlier which is just that this 3rd party package does not ship binaries built for FreeBSD. Everything else has worked exactly the same as on Linux.

Now I am speculating, but I think it would take less work to go through tree-sitter route. Seems that emacs tree-sitter repo already supports Elixir. And then we would need to write Elixir specific queries for combobulate, which supports incremental selection à la expand-region.

I learned from a google search that these days upstream tree-sitter provides WebAssembly bindings.

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.

This is a plugin that provides a simple way to use the tree-sitter in Neovim and also provides functionalities like highlighting, etc.

From the tree-sitter side, I am tracking https://github.com/tree-sitter/tree-sitter/issues/1942

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.

u/lewis6991 I think the biggest performance gain was made by tree-sitter itself: https://github.com/tree-sitter/tree-sitter/pull/2085

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).

The following discussion here. TS query cannot be incremental, that is why I regard it as design fault.

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.
