objarni / buz.py
Last active August 29, 2015 14:06
A code sketch of a nice simple asynchronous messaging library I'd like to call "Buz" - standing for lots of chatter - buzz, and it's a MessageBus architecturally. And it's a TLA that's nice to say ;)
from buz import Buz, Inbox
buz = Buz()
# Sending a message asynchronously is ridiculously simple
def long_computation(self):
# looong slow algorithm (possibly involving polling I/O ports!)
buz.publish(SomeMessage(..))
# Remember the hell we go through to do things in parallell

Zoo DDD tests
# Rule 1. Carnivors and herbivors cannot live together.
# For example, moving a lion to an enclosement with a zebra is not good, since the zebra will be eaten.
zoo = Zoo()
zoo.add_fenced_enclosure('Fenced area 1')
zoo.add_fenced_enclosure('Fenced area 2')
zoo.add_carnivore('lion', 'Fenced area 1')
zoo.add_herbivore('zebra', 'Fenced area 2')
assertThrows(zoo.move_animal('lion', 'Fenced area 2'))
# Rule 2: Herbivors can live side-by-side.
