将 AppleScript 翻译成 Python appscript (`do javascript`)

Question

This is the AppleScript template:

tell application "Adobe Photoshop CS5"
  set theFile to alias “Application:Documents:MyFile” open theFile
  do javascript (file <path to Emboss.jsx>) with arguments { 75,2,89 }
end tell

And I would like to translate that to Python appscript. Unfortunately, I cannot figure out how to translate the do javascript . Any ideas?

I don't even know how to find it out. Maybe I know AppleScript too less. Is do a keyword? Or is it a command I am sending to the application? Is javascript a parameter of do ? Or does do javascript belong together (as a command with a space)?

Answer 1

I still don't exactly know how to translate the above (and more generally: I don't know how to translate any generic AppleScript code to Python appscript).

However, for the above case, I found that there is the command do_javascript . It doesn't seem to execute files though but rather executes the given JS code string directly.

Eg, this works:

from appscript import *
import os, sys

ps = app("Adobe Photoshop CS5")

filelist = sys.argv[1:]

jsCode = """
var g_StackScriptFolderPath = app.path + "/Presets/Scripts/" 
var runMergeToHDRFromScript = true; 
$.evalFile(g_StackScriptFolderPath + "Merge to HDR.jsx");
mergeToHDR.mergeFilesToHDR(%s, true);
""" % (repr(filelist),)

ps.do_javascript(jsCode)

To translate generic AppleScript to appscript , use the ASTranslate tool available from the appscript web site here . It is not always able to successfully translate due to the quirks and bugs in the script definitions of some applications but it is a good place to start.
