Hi, Right now I am in a project writing a Simulation engine, and we are right now in the process of evaluating a script engine.
The basic principle is a C++ engine simulating the environment and scriptable agents interacting with the environment. But the current design has a special requirement to that scriptability and my current knowledge of the API of Python isolated two problems 1) Threads: the simulation is going to be run in a very parallel environment with several CPUs and http://docs.python.org/c-api/init.html#thread-state-and- the-global-interpreter-lock there is a global lock mentioned. Does that mean that the python code can not benefit from this ? 2) The script has to hand back control to the C++ framework without increasing the C execution stack. and be able to resume the execution at a later point. I try some pseudo code here to explain // C++: ctx = new ExecutionContext(); ctx->run(); while(ctx->stillRunning()) { otherStuff(); ctx->resume(); } ...... // Python y=21 ... .. # Here the execution is suspended und control handed back to the C++ code suspend y+=12 end I hope that makes it clear. I did not see a way to implement this with the python interpreter. I am hoping to be proven wrong Thanks in advance Greets Peter -- http://mail.python.org/mailman/listinfo/python-list
