I have the following AppleScript which I have also converted to Python:

tell application "CodeWarrior IDE" activate open file file1 disassemble file file2 set xText to (get text of document 1) end tell

I had some difficulty converting the last command into Python, but the below should work (or so I have been told):

import CodeWarrior, time

cw = CodeWarrior.CodeWarrior(start=1)
time.sleep(5)
cw.activate()
cw.open(file1)
cw.disassemble_file(file2)
time.sleep(5)
xtext = app('CodeWarrior IDE').document[1].text

However, instead of the text that I expect, xtext is equal to 'app('CodeWarrior IDE').document[1].text.all'

Bill Fancher looked at CodeWarrior and said that it is returning cText which is not being handled by Python.

I made a typo: xtext = app('CodeWarrior IDE').document[1].text should be: xtext = cw.get(CodeWarrior.text(CodeWarrior.document(1)))

Robin, you have to give a more complete example. I can get neither the applescript nor the Python program to work. I've filled in valid filenames for file1 and file2, but the Applescript keeps giving the error "CodeWarrior IDE 4.2.5 got an error: Bad name for file. some object".

Could you maybe create a sample soucre file (plus project?) and the real AppleScript you used, and pack it all up?

I will create a project and attach it, however, you cannot use CodeWarrior IDE 4.2.5 because there is are bugs in it that have to do with AppleEvents. You have to use v 5.0 of the IDE.

Here is a project, applescript and python script. You will have to change the paths in the script to wherever you place the project.
Also, there is a bug in the last line of the python script because I can't remember the exact syntax I had to use to capture the text from CodeWarrior. Maybe you will have better luck than me.

Oops! I forgot to check the stupid (and unneccessary) checkbox.

I left out the python script. I will upload a new file

I removed the "disassemble file" bit and did that manually (it indeed doesn't work in CW7) and ran the Python script under the debugger.

The strange thing is that the reply AppleEvent indeed does not have a "----" item (this is the return value), so cw.get() is "right" in returning None. (Note that the problem sketched by Bill Fancher, missing support for cText, would have shown up differently: you would have gotten an aetypes.Unknown('ctxt', data) object back).

If you want to see this for yourself run the script under the debugger. The last line, by the way, should be "text = cw.get(CodeWarrior.text(CodeWarrior.document(1)))"

After the aesend() call in cw.get() you'll see there's no ---- argument.

I vaguely remember about there being a second protocol for send replies to AppleEvents (maybe especially for big replies?) but a quick look through the documentation hasn't revealed anything. I'll ask on the SIG whether anyone has any ideas.

As Bill Fancher explained this turns out to be an ideosyncracy in CodeWarrior (and possibly other TextEdit-related programs). The text of the window is actually multiple text runs. In this case there's only one, so the correct lines in Python to grab the text of the window is txt = cw.get(CodeWarrior.editor_document(1).text(1))

AppleScript apparently has a workaround for this situation, but I think that for now I'll flag this as "won't fix".
