}

LSP.sublime-settings

Place the following snippet in the LSP.sublime-settings. (Preferences -> Package Settings -> LSP -> Settings)

{
  // General settings

    "selector": "source.zig",
    // There are two ways to set config options:
    //   - edit your `zls.json` that applies to any editor that uses ZLS
    //   - set in-editor config options with the `settings` field below.

        // "enable_build_on_save": true,

        // omit the following line if `zig` is in your PATH
