Save this file as brackets/src/extensions/user/HelloWorld/main.js
to see it running in Brackets. (You'll need Sprint 10 or later.)
/*jslint vars: true, plusplus: true, devel: true, nomen: true, regexp: true, indent: 4, maxerr: 50 */
/*global define, $, brackets, window */
/** Simple extension that adds a "File > Hello World" menu item */
define(function (require, exports, module) {
"use strict";
var CommandManager = brackets.getModule("command/CommandManager"),
Menus = brackets.getModule("command/Menus");
// Function to run when the menu item is clicked
function handleHelloWorld() {
window.alert("Hello, world!");
}
// First, register a command - a UI-less object associating an id to a handler
var MY_COMMAND_ID = "helloworld.sayhello"; // package-style naming to avoid collisions
CommandManager.register("Hello World", MY_COMMAND_ID, handleHelloWorld);
// Then create a menu item bound to the command
// The label of the menu item is the name we gave the command (see above)
var menu = Menus.getMenu(Menus.AppMenuBar.FILE_MENU);
menu.addMenuItem(MY_COMMAND_ID);
// We could also add a key binding at the same time:
//menu.addMenuItem(MY_COMMAND_ID, "Ctrl-Alt-H");
// (Note: "Ctrl" is automatically mapped to "Cmd" on Mac)
// Or you can add a key binding without having to create a menu item:
//KeyBindingManager.addBinding(MY_COMMAND_ID, "Ctrl-Alt-H");
// For dynamic menu item labels, you can change the command name at any time:
//CommandManager.get(MY_COMMAND_ID).setName("Goodbye!");
