Format on save for ERB and Ruby files in Zed IDE

Something that I really wanted when working with (Zed)[https://zed.dev] and Ruby on Rails was format on save ability for my .rb and .erb files. The setup is simple so I thought I'd give it a share:

First open your settings.json file with cmnd + , or going to Zed -> Settings -> Open Settings.

Then add a key for languages with the following:

{
  ...other_settings_here,
  "languages": {
    "Ruby": {
      "format_on_save": "on",
      "formatter": {
        "external": {
          "command": "./bin/bundle",
          "arguments": [
            "exec",
            "rubocop",
            "--auto-correct",
            "--stdin",
            "corrected.rb",
            "--stderr"
          ]
        }
      }
    },
    "ERB": {
      "formatter": [
        {
          "external": {
            "command": "sh",
            "arguments": [
              "-c",
              "f=erblinttemp_$RANDOM$RANDOM.html.erb; cat > $f; erblint -a $f &>/dev/null; cat $f; rm $f;"
            ]
          }
        },
        {
          "external": {
            "command": "htmlbeautifier",
            "arguments": []
          }
        }
      ],
      "format_on_save": "on"
    }
  }
}

There you have it format on save for your template files and ruby files ready to go.
