Commands API

The frontend wrappers live in src/lib/tauri.ts. All commands return promises that reject with a string message on error.

Show persistence

/** Saves to an explicit path, validating before writing. */
function saveShow(show: Show, path: string): Promise<void>;

/** Opens a native save dialog, saves, and returns the chosen path (or null). */
function saveShowAs(show: Show): Promise<string | null>;

/** Loads from a path, or opens a dialog when path is omitted. */
function loadShow(path?: string): Promise<LoadedShowFile | null>;

/** Returns true without prompting when isDirty is false. */
function confirmDiscardChanges(isDirty: boolean): Promise<boolean>;

/** Opens a PDF picker and imports a show (or null when cancelled). */
function importPdfShow(): Promise<ShowFile | null>;

Types:

type LoadedShowFile = {
  path: string;
  showFile: ShowFile;
};

Window management

/** Opens a new live display window; returns its generated label. */
function openDisplayWindow(): Promise<string>;

In the UI this is invoked directly in perform-toolbar.tsx via invoke("open_display_window").
