Running Scripts at Startup

myDocument.viewPreferences.horizontalMeasurementUnits = MeasurementUnits.points;

myDocument.viewPreferences.verticalMeasurementUnits = MeasurementUnits.points;

var myPage = myDocument.pages.item(0);

//Insert a custom label using insertLabel. The first parameter is the

//name of the label, the second is the text to add to the label.

myRectangle.insertLabel("CustomLabel", "This is some text stored in a custom label.");

//Extract the text from the label and display it in an alert.

var myString = myRectangle.extractLabel("CustomLabel");

alert("Custom label contained: " + myString);

Running Scripts at Startup

To run a script when InDesign starts, put the script in the Startup Scripts folder in the Scripts folder (for

more information, see “Installing Scripts” in

Adobe InDesign CS5 Scripting Tutorial

OTE

Scripts run in the session ExtendScript engine when InDesign starts can create objects and

functions that will be available to other scripts for the duration of the session. For more information, see

“Session and Main Script Execution” on page 18

Session and Main Script Execution

InDesign has two ways to run a JavaScript,

session

and

main

. These names correspond to the

ExtendScript “engine” used to run the script.

By default, when you run an InDesign JavaScript, the script is interpreted and executed by the “main”

ExtendScript engine, which is destroyed when the script completes execution. Script objects created by

the script do not persist.

Scripts run in the session engine can create objects that persist until you close InDesign. You can refer to

these objects from other scripts run in the

session

engine. To set the

session

engine as the target of an

InDesign JavaScript, add the following line to the start of your script.

#targetengine "session"

You can create your own persistent ExtendScript interpretation and execution environment. To do this, use

the

#targetenging

statement and provide your own ExtendScript engine name, as shown in the

following script fragment:

#targetengine "adobe"
