Description

Add support for Julia.
This is my first time contributing code to an open-source project – please let me know if I do anything wrong!

How Has This Been Tested?

Checklist

• I have performed a self-review of my own code
• I have added tests to cover my changes

Oh no, it looks like it might not be as easy as I first thought. I wrote a test, and docstrings are not spell-checked (only simple inline comments).
It looks like something similar happened with Python, and this might be too difficult for me (I have no experience with Rust or TreeSitter). @elijah-potter, what would be the way forward now?

[elijah-potter]

Honestly, you might be able to get away with copy-pasting harper-python into harper-julia and using grep to make it work for Julia with the Julia Tree-sitter library.

Ok, I'll try that then.

…I tried, and it's not that easy. I initially thought this would just take a couple of hours, but now that it's turned out to be more complicated, I think I currently don't have the skills or time to make this work.

I think I might be able to knock this out. Do you mind if I push a few commits here to build off of your work? For me, the hard part is building out test cases, so you've already done most of the work here.
