How to format Ruby using rubyfmt?

[raphael-fournier]

Hello,

I'm trying to set up the Zed to automatically format Ruby files using rubyfmt upon saving.
Here is the configuration I currently have in my settings.json:

{
  "Ruby": {
    "format_on_save": {
      "external": {
        "command": "rubyfmt",
        "arguments": ["-i", "--", "{buffer_path}"]
      }
    }
  }
}

This configuration isn't working. I'm uncertain if the {buffer_path} argument is correctly recognized in this context, even though it works fine with the prettier command. For more details on rubyfmt CLI specs, see its github readme.

If anyone has successfully configured rubyfmt with Zed, could you share your configuration or point out what might be going wrong with mine?

Thank you!

FWIW, here's what I use:

      "format_on_save": {
        "external": {
          "command": "rubyfmt",
          "arguments": ["--fail-fast"]
        }
      }
