I'm looking into using ast-grep fo linting ReScript. What rules should I investigate?

Aha! For whatever reason, on my linux machine, it could auto-migrate to the latest version of tree-sitter. On my mac, I was left without that, but managed to add it manually to a fork of the current tree-sitter repo.

Full install instructions for tree-sitter are now:

• Install tree-sitter (in my case via brew)

> brew install tree-sitter

• Initialize the tree-sitter config, which, in my case, spit out a file at ~/.config/tree-sitter/config.json

> tree-sitter init-config

• Add the directory where you’d like to place the repo to the parser-directories in that config file.
• cd into said path
• Clone and cd into the tree-sitter-rescript repo (currently my fork has the needed files).

> git clone https://github.com/cwstra/tree-sitter-rescript
> cd tree-sitter-rescript

• Compile the parser file.

> tree-sitter build

• Profit!

> tree-sitter dump-languages
(Should output promising information)
> tree-sitter parse test/highlight/functions.res
(Should output an ast)
