### Configure formatters via LSP

Source: https://github.com/zed-extensions/nix/blob/main/README.md

Configure formatters through LSP by setting the formatting command in the initialization options for nil (or nixd). Use 'alejandra --quiet --' or 'nixfmt'.

```jsonc
{
  "lsp": {
    "nil": {    // or "nixd":
      "initialization_options": {
        "formatting": {
          "command": ["alejandra", "--quiet", "--"]  // or ["nixfmt"]
        }
      }
    }
  }
}
```

### Configure Nil LSP settings

Source: https://github.com/zed-extensions/nix/blob/main/README.md

Configure the nil language server in Zed's settings.json to ignore the 'unused_binding' diagnostic. See the Nil LSP Configuration Docs for more options.

```json
{
  "lsp": {
    "nil": {
      "settings": {
         "diagnostics": {
          "ignored": [ "unused_binding" ]
        }
      }
    }
  }
}
```

--------------------------------

### Configure formatters via Zed

Source: https://github.com/zed-extensions/nix/blob/main/README.md

Configure formatters through Zed itself by setting the external formatter command and arguments for Nix files. Use 'alejandra' or 'nixfmt'.

```jsonc
{
  "languages": {
    "Nix": {
      "formatter": {
        "external": {
          "command": "alejandra",  // or "nixfmt"
          "arguments": ["--quiet", "--"]
        }
      }
    }
  }
}
```

--------------------------------

### Only use Nil language server

Source: https://github.com/zed-extensions/nix/blob/main/README.md

Configure Zed to use only the nil language server for Nix files, disabling nixd.

```json
{
  "languages": {
    "Nix": {
      "language_servers": [ "nil", "!nixd" ]
    }
  }
}
```

--------------------------------

### Only use Nixd language server

Source: https://github.com/zed-extensions/nix/blob/main/README.md

Configure Zed to use only the nixd language server for Nix files, disabling nil.

```json
{
  "languages": {
    "Nix": {
      "language_servers": [ "nixd", "!nil" ]
    }
  }
}
```

--------------------------------

### Configure Nixd LSP settings

Source: https://github.com/zed-extensions/nix/blob/main/README.md

Configure the nixd language server in Zed's settings.json to suppress the 'sema-extra-with' diagnostic. See the Nixd LSP Configuration Docs for more options.

```json
{
  "lsp": {
    "nixd": {
      "settings": {
        "diagnostic": {
          "suppress": [ "sema-extra-with" ]
        }
      }
    }
  }
}
```
