Can I control InDesign from an outside script? Can an InDesign script interact with the OS?

AppleScript is Apple's main script language, they also have a JavaScript engine. Common to both of is the use of AppleEvents. When I search for Python and AppleEvent, I find some references dating back to 2008, so eventually it is still built in.

Instead of translating the entire Terminology (aka scripting object model in ExtendScript), I'd try to get the doScript method going. If that fails (e.g. removed from Python), have a look at the man page for osascript.

A follow-up question, please: is there a way to control InDesign with a single script that can run on both Mac and Windows?

@Loic.Aigon , @Kasyan Servetsky , @rob day , thank you very much for your replies, they're very helpful!

Here’s a simple example that opens a selected Indesign file in the Finder:

tell application "Finder"
	activate
	set the selected_items to the selection
	repeat with aFile in selected_items
		set thePath to (aFile as Unicode text)
		tell application id "com.adobe.indesign"
			try
				set doc to open alias thePath
				--do samething to the open document
				--close doc saving yes
			end try
		end tell
	end repeat
end tell

I wrote a script for this task: Batch processor.

Here are examples of scripts that can be run from it.

Note a couple of scripts in the AppleScript section. They can give you an idea of how to extract info from InDesign files and put it into another app: e.g. an Excel spreadsheet.

Can I control InDesign from an outside script?

Many years ago I wrote a stand-alone app in AppleScript in Xcode. It was before ScriptUI became available in JS so the only option for me was to draw the dialog box in Xcode. I guess (but can’t check at the moment) that you can compile such an app in the Script Editor or Script Debugger if you want, for some reason, to control InDesign from outside instead of running a script from the Scripts panel,

As @rob day mentioned, Applescript is your way to go. There were some great manuals in the past but most of them if not all remain valid:

Once that said, to answer item #2, if you want to write an external file such as a log, you can do it with Javascript and the File Object. You can even mix Applescript for your main logic and request some javascript code in the middle (see do script).

Hi @orib7317974 , with AppleScript you can script both InDesign and the Finder within the same script. With Javascipt you could write InDesign and text files, but you can’t fully script the Finder.
