Add Odin support

[Igonato]

Adding Odin support (#182). Currently there are false positives with CONSTANTS in enum variant values and bit_fields size:

Can use another pair of eyes, I might be missing a way to make a query that can handle this case. It is also possible that's the grammar needs changing. Grammar for reference: https://github.com/tree-sitter-grammars/tree-sitter-odin/blob/master/grammar.js

What do you think?

This looks great so far, but oof, I have no idea how to read Odin. There's also no Odin support in my tree-sitter visualizer, so debugging this will take some time. I'd be happy to merge this as is though if you want it in now?

[Igonato]

Hey, I'd like to spend more time on it, just got distracted with the holidays (Happy New Year btw 🎉). I'm reading up on Tree-sitter, I wanted to learn how to make a parser anyway, then I'll know for sure if it's limited by the grammar or just needs a better query.

Happy new year! Sounds good. I find that adding tests helps with the iteration speed a lot. Happy to answer any questions, but I have no experience with Odin specifically 🙂

[Igonato]

Oh, I had some tests already, just didn't include them in the PR. They immediately flagged the duplication and I figured better do a proper fix instead of figuring how to suppress those and submitting a partial solution.

Odin is quite simple, no-nonsense, boring in a good way and the community is awesome! If you find a spare hour, I would encourage you to look up some interviews with the creator of Odin @gingerBill and give the language a try. I found that it simplicity brought back joy to my programming life, serving as a nice break from the Web and Rust stuff.

[Igonato]

Didn't mean to do that. Sorry

[Igonato]

I wanted to tidy things up and force-pushed your current main to my working branch, turns out that closes the PR, TIL I guess.

From what I was able to gather, grammar is indeed needed to be changed, I ended up forking it and publishing it under a different crate since the original doesn't seem to be active. I also merged changes from one of the more active forks, not sure that it was necessary for Codebook specifically, and in hindsight it wasn't, but I think it shouldn't hurt. If you want to verify that I didn't do anything funny, you can:

git clone [email protected]:Igonato/tree-sitter-odin-codebook.git
cd tree-sitter-odin-codebook
tree-sitter generate

And check the diff. My tree-sitter --version is 0.26.3.

I have some thoughts how we can better handle grammars in this project, I'll write that a new issue since it's unrelated to the PR. Cheers!

[Igonato]

Rebased on the latest main and ran cargo test. Please let me know if anything else is needed

[blopker]

Hey! Nice, I've had to fork a few grammars myself, which is kind of a pain. I saw your proposal issue. I need to investigate a bit, but I'll reply to that issue.

Anyway, this looks great! Thank you.
