Any particular reasons you were looking at that old commit ? the latest master branch seems to have a highlights.scm file

tree-sitter seems to support records as well as a lot of other things. That said, it might not be exposed in csharp mode yet. In my experience it has been super easy to add new constructs. Some time in the future I will make this user customizable as well. Maybe you want something to be highlighted as keywords which has a different default. That sort of thing.

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.
