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.

BTW:

While Emacs 29.1 comes with "treesitter" built-in, you still need to manually build and install any treesitter language plugin implementing the actual language specific parser. This can be fiddly and frustrating doing it yourself.

I had a quick success with using this convenience script: https://github.com/casouri/tree-sitter-module/. It provides fully-automated builds for the most popular languages (including typescript, c and c++).

This is how it works for "typescript":

1. Clone the repository: https://github.com/casouri/tree-sitter-module/

2. Install "build-essentials" (providing a c/c++ compiler if you're on Linux).

3. run "./build typescript" from within the repo

4. Copy the resulting shared library from "dist/libtree-sitter-typescript.so" into your "~/.emacs.d/tree-sitter/".

5. Open a random typescript file and try "M-x typescript-ts-mode" which should not give you any error but instead nice syntax highlighting.

You might find there is a treesitter plugin for your language available and it is even supported by "tree-sitter-module" but there is still no major mode, yet. Happened to me for Perl 5.

I will look into building my own tree sitter grammars using https://github.com/casouri/tree-sitter-module as you suggest.

Some time ago I followed this guide https://vxlabs.com/2022/06/12/typescript-development-with-em...

Also this https://github.com/casouri/tree-sitter-module/issues/13

I've downloaded and generated the libraries for the various languages from: https://github.com/casouri/tree-sitter-module

Third, I'm using tsitter in emacs29. I have https://github.com/casouri/tree-sitter-module installed as a sub-module in ~/.config/emacs, and have a symlink called tree-sitter to ./tree-sitter-module/dist (built by ./tree-sitter-module/batch.sh) . I'm mentioning the tsitter config here since I'm using python-ts-mode which is tree-sitter aware.

I'd recommend checking out https://github.com/casouri/tree-sitter-module for building the native treesit libraries that are required to enable the various languages.

The author of the built-in tree-sitter implementation has published this repo with a build script to help you build various grammars: https://github.com/casouri/tree-sitter-module
