Cancelling script by 'Esc'

[yasushisakai]

Hi,

Cancelling scripts seems possible via VbScript by hitting 'esc' (Rhino.sleep(0)). I tried the same technique with python (rhinoscriptsyntax.Sleep(0)), and rhino eventually hanged-out. Is it possible to cancel a script with a different way?

The main reason for doing this is because I sometimes can't imagine when the script will end,
when doing form finding. It will be good if I can decide when to stop while looking the results. Maybe multi-threading?

All of the RhinoScript functions check to see if the escape key was pressed and abort if it was. I didn't want to add this overhead to the python implementation for every function, so I decided to break this out into a separate function that you can call when you actually want to check for the escape key. The function is called escape_test and is defined in the scriptcontext module.

Python Code:

import scriptcontext
 
x = 0
for i in xrange(100000):
    x = x+i #pretend this is a long running loop
    scriptcontext.escape_test() #will throw an exception if the escape key was pressed
