While some parts of the IDLE application can find uses in

other situations, e.g. rpc.py, PyShell.py is not so intended.



One can't generally expect to dive into the middle of some

code and apply it arbitrarily.   If you want to go to the

effort of figuring out how IDLE works, then of course you

are welcome to mine it for whatever gold you can find.



If you are just trying to run IDLE, there should be a script

named idle in the same bin directory where your python2.3

executable lives.  You can also try running python and then



from idlelib.PyShell import main

main()



(That happens to be the contents of the "idle" script)



I will probably add a global default for use_subprocess

when I get a chance.

Sorry, I can't help you with that. I'm tempted to ask

questions like "what are you trying to do" and "why are you

using IDLE for that" and "do you understand enough of how

IDLE works to be able to use IDLE" but then if you answer

them I still wouldn't be able to help you, because I have no

time. I recommend that you go to comp.lang.python or the

idle-dev at python.org list and present your problem there,

perhaps with answers to the above questions.

Thanks a lot, it helped a bit setting it to False,

unfortunately the second time around i got an error message

about RecentUsed files:

Error: 1

Any more suggestion welcome,

Right. It looks like this variable is only defined if main()

in the same module is run. As a workaround, try this:



from idlelib import PyShell

PyShell.use_subprocess = True # or False, whatever you prefer.



I guess the proper fix should be to give use_subprocess a

default variable through an assignment outside main().
