Welcome to Vanilla!
If Go and ZeroMQ had a baby, and that baby grew up and started dating PyPy, and they had a baby, it might look like Vanilla.
Overview
Vanilla allows you to build concurrent software in Python. Vanilla programs are structured around independent coroutines (greenlets) which communicate with each other via Pipes. Pipes are similar to channels in Go programming.
There's no callback crazyness and no monkey patching. Vanilla strives to be as explict and straightforward as possible.
Documentation
Here's how it looks:
You spawn coroutines:
h = vanilla.Hub()
def beat(message):
while True:
print(message)
h.sleep(1000)
h.spawn(beat, 'Tick')
h.spawn_later(500, beat, 'Tock')
# Tick / Tock / Tick / TockCoroutines communicate via Pipes:
h = vanilla.Hub()
sender, recver = h.pipe()
h.spawn(sender.send, 'Hello World')
recver.recv()
# 'Hello World'Pipe-fu; inspired by reactive functional patterns, Pipes can be chained:
h = vanilla.Hub()
p = h.pipe().map(lambda x: x*2)
h.spawn(p.send, 4)
p.recv()
# 8In Vanilla, everything is a Pipe. Here's how TCP looks:
h = vanilla.Hub()
server = h.tcp.listen(port=9000)
# server is a Recver which dispenses new TCP connections
conn = server.recv()
# conn is a Pipe you can recv and send on
message = conn.recv()
conn.send("Echo: " + message)Installation
Vanilla works with Python 2.6 - 2.9 and PyPy.
