Zed and Standard Ruby

I’ve been using Zed as my main editor for the last two weeks or so. It feels great, lean, and fast compared to VS Code that I’ve been using for years. Last time I tried Zed, there were no possibilities to install extensions or add/customize language servers, but this has changed, and there are more and more extensions being built.

I missed one particular feature while working with Ruby code, formatting with Standard ("…a linter & formatter built on RuboCop…") so I set out on a mission to try to create one, how hard can it be?

Turns out it was a bit harder than I thought but not too bad. You have to write Rust, which I had never done before. Luckily, there were a lot of extensions to look at, and with that, I could quite quickly throw together a working extension that wraps Standard’s language server and uses that for linting and formatting.

The implementation is quite naive, and I'm not sure if I should submit it to Zed's extension library. We'll see. But until then, you can clone/download the code and use the "install dev extension" feature to use it yourself.

To enable it, you can add this snippet to your config.json:

"languages": {
  "Ruby": {
    "language_servers": ["standardrb"]

Feel free to contribute or give feedback. I'm sure there are a lot of improvements that can be made, but for now, it works for me, and I have a huge lack of time to work on it further. I hope it can be useful for someone else as well.
