Twisted TV - fairly simple processes

Tuesday: Went to the office and worked hard, but unfortunately not on my game. Kept thinking that there had to be a simpler way of implementing coroutines.

Returned home in the evening and improved my code by taking things out, resulting in fsp.py - Fairly Simple Processes.

It means that I can write multitasking code like this, hopefully simplifying the logic a bit. It's all part of a wild and wacky experiment based on reading a few articles about Erlang.

from fsp import spawn, run

def producer(consumers):
    while True:
        yield True
        for consumer in consumers:
            consumer.send(me)
       
def consumer():
    while True:
        yield wait()
        msg = recv()
        print me, msg

c = spawn(consumer)
for i in xrange(10):
    spawn(producer, (c,))
run()

Next: Re-integrate sprite stuff.

renderer.send(('move', me, x, y))

renderer << ('move', me, x, y)

while True:
    yield wait()
    while ready:
        msg = recv()
        *** do something with msg ***

while True:
    yield wait()
    for msg in me:
        *** do something with msg ***
