I don't think there is currently a way to force a running wren script to terminate prematurely. However, in a fork I created, I hacked in a function to exit the VM here.
Essentially I added a new boolean value to the WrenVM
struct called earlyExit
which is checked each instruction cycle for the VM. If earlyExit
was ever set to true while the VM is still executing code, it raises a runtime error. This way, in another thread, you can set this value (in my implementation using a function called wrenEarlyExit
) to effectively stop the VM by the next instruction.
I don't know if this is actually the most optimal way to do this. You'll need another thread running to call the function to stop the VM. I haven't really tested to see whether this is thread safe to begin with, and I also don't know if stopping the VM prematurely might corrupt it or put it in an unusable state. From the few examples I've done with this, the VM seems to interpret and call functions afterwards without issue, though your mileage may vary.

This solution is very good! but have to edit wren code ..
