How to find app location

Scripting
1

I want to use the app’s internal icon images in my script UI (in my case, line end shapes). Simply specifying the app location like “Applications/Glyphs 3.app/Contents/…” will cause an error for the users who rename the app. Is there a safe way to refer to the app’s location?

Usually you can use

bundle = NSBundle.bundleForClass_(NSClassFromString("GSFont")) # (1)
image = bundle.imageForResource_("imageName") # (2)
  1. Find a class that is in the bundle that the image is in (if it is in the main app and not in e.g. GlyphsCore, you can use NSBundle.mainBundle()
  2. the full file name of the image without the suffix.

Thanks, it works!
