Accessing OTF stylistic sets vis applescript

[BorisBlocksberg]

Hi community,

I’m trying to access the stylistic sets of a font via applescript. Unfortunately, my script is not behaving as it should. Although it works in principle. Here is the script so far:

tell application "Adobe InDesign 2022"
	tell every character of selection
		set OTF stylistic sets to 0
	end tell
	set varNum to number of characters of selection
	repeat with i from 1 to varNum
		tell character i of selection
			set myVar to 7 -- what i actually want is: random number from 0 to 18
			set OTF stylistic sets to myVar as integer
		end tell
	end repeat
end tell

No matter which font I use, I get the following result: 

What am I doing wrong?

Why are you not using Paragraph and Character Styles? No script needed.

Because I want to randomise it in the end --> each character its won shape/stylistic set

Hi @BorisBlocksberg , I’m not sure I can help, but the OTF stylistic sets property is a number and not a reference to the set object or its name—there doesn’t appear to be a collection of a font’s OTF style sets in either AppleScript or Javascript.

Maybe someone else can explain what the number refers to–apparently it can be anything. So this returns 1:

tell application id "com.adobe.indesign"
	
	set OTF stylistic sets of selection to 1
	get OTF stylistic sets of selection
	--returns 1
	
end tell

but gives me this for MinionPro:

This does not throw an error and returns 999:

tell application id "com.adobe.indesign"
	
	set OTF stylistic sets of selection to 999
	get OTF stylistic sets of selection
	--returns 999
	
end tell

and gives me this:

Well, its not a solution but it brings light into the darkness. Thank you so much for testing! At least I have learned that it is not principally due to the script.
