Getting Started

Let's start to create an HelloWorld extension for StarUML 2. Full source codes of HelloWorld extension are available at https://github.com/staruml/HelloWorld.

Create an extension

First we need to create an extension folder. Open your extensions folder.

  • Mac OS X: ~/Library/Application Support/StarUML/extensions/user
  • Windows: C:\Users\<user>\AppData\Roaming\StarUML\extensions\user
  • Linux: ~/.config/StarUML/extensions/user

Create a new folder HelloWorld in your extensions folder.

Create main.js

Create main.js in the new extension folder. main.js is the entry point to be executed when StarUML is started. Extensions should follow CommonJS style module because requirejs is used to load extensions.

define(function (require, exports, module) {
    "use strict";
    // ...
});

Load modules

StarUML provides several modules providing functions, classes, or events. To find all the modules, refer to API reference. To load a module, use app.getModule() function like as below:

var MenuManager = app.getModule("menu/MenuManager");

We will create a command named tools.helloworld and add a menu item named HelloWorld under Tools menu. When user selects the menu item, the command will be executed to show alert dialog with message "Hello, World!".

define(function (require, exports, module) {
    "use strict";

    var Commands       = app.getModule("command/Commands"),
        CommandManager = app.getModule("command/CommandManager"),
        MenuManager    = app.getModule("menu/MenuManager");

    // Handler for HelloWorld command
    function handleHelloWorld() {
        window.alert("Hello, world!");
    }

    // Add a HelloWorld command
    var CMD_HELLOWORLD = "tools.helloworld";
    CommandManager.register("Hello World", CMD_HELLOWORLD, handleHelloWorld);

    // Add HellWorld menu item (Tools > Hello World)
    var menu = MenuManager.getMenu(Commands.TOOLS);
    menu.addMenuItem(CMD_HELLOWORLD);
});

Run and Debug

If you finished editing main.js, then just restart StarUML. However, restarting whenever you modified codes is very tedious. So, just reload by pressing Ctrl+R (Cmd+R for Mac) or selecting Debug > Reload menu item.

NOTE: Sometimes adding menu items may not affected by reloading. Then, you need to restart.

It is useful to use DevTools to debug an extension. To open DevTools, select Debug > Show DevTools. You can see all console errors and logs.

Define package.json

If you consider to distribute your extension to other users, you need to create a package.json file containing metadata for the extension.

{
    "name": "your_id.helloworld",
    "title": "HelloWorld",
    "description": "HelloWorld extension example.",
    "homepage": "https://github.com/staruml/HelloWorld",
    "version": "0.9.0",
    "keywords": ["example", "helloworld"],
    "author": {
        "name": "Your Name",
        "email": "[email protected]",
        "url": "https://github.com/your_id"
    },
    "license": "MIT",
    "engines": {
        "staruml": ">=2.0.0"
    }
}

Restart StarUML and then check whether your extension is properly shown in Extension Manager or not. (select Tools > Extension Manager and click Installed tab).

Distribute your extension

To allow other users to install your extension, there are several possible ways:

  1. Distribute as ZIP archive. Zip the extension folder HelloWorld as HelloWorld.zip and just unzip the file in other user's the extensions folder explained above.
  2. Distribute via Github URL. Users can install from Github URL. In Extension Manager, click Install from URL and enter the Github URL (e.g. https://github.com/staruml/HelloWorld) and press Install button.
  3. Distribute via Extensions Registry. If you want to register official extensions registry. Please contact us ([email protected])
