Scripting Environment

5. Enter the code below into the editor window:

Window.alert("Hello World.");

6. Within the Toolkit, run the script you just created, by selecting Debug > Run or using the

Run icon button on the toolbar (a rightward-pointing triangle).

7. Verify that you can see an alert popped from the context of the Version Cue client.

There is an even terser “Hello World” script we can write, using the dollar ($) object, which is

available as a debugging aid within the ExtendScript implementation of JavaScript and emits

output to the JavaScript console of the ESTK:

$.writeln("Hello World");

Follow these steps:

1. Launch the Version Cue client if it is not already running.

2. Launch the installed ExtendScript Toolkit 2, if you have not already done so.

3. Within the Toolkit, enter the script below directly into the command line of the JavaScript

Console (an edit-box at the top of the Console panel):

$.writeln("Hello World");

4. Press Return (Enter) to have the code execute and display its results to the JavaScript Con-

sole.

5. Verify that you see a message printed out, followed by “Result: undefined.” The writeln

function of the dollar class returns “undefined.”

Example: List Version Cue Servers

In the next example, we execute code to list the Version Cue Servers known to the CS3 client.

Note that this and also Example 2 you will execute directly against the Bridge main scripting

engine as if the script were installed on the client machine, rather than sent by a Version Cue

Server. This means you will be able to set break-points in them directly from the ExtendScript

Toolkit IDE, which you would not be able to do with a server-driven script— in the latter case,

you need to use $.bp().

NOTE: To make sure that the global objects added by the Version Cue client scripting interface

are available, you have to make sure that the Version Cue client SDK is loaded, if you

want to run this script in a context such as the main Adobe Bridge CS3 scripting

engine. See “Enabling the Version Cue Client Scripting Interface from other Scripting

Contexts” on page 28.

NOTE: Note that the shared library exposing the Version Cue client scripting interface is

loaded automatically when you navigate into a sample like Sample CustomProject.

Alternatively, you can call VersionCueSDKLoader.loadSDK() and then once you are

finished running client scripts, you can call VersionCueSDKLoader.unLoadSDK().
