collection of modules to build distributed and reliable concurrent systems in Python.
- Python from 2.6 to 3.x
- A platform supported by libuv <https://github.com/joyent/libuv>
A simple example showing how to create a consumer and use other actor function to feed it.
import flower messages =  sources =  def consumer(): # wait for coming message in the current actor while True: source, msg = flower.receive() if not msg: break print("got message from %s: %s" % (source.ref, msg)) def publisher1(ref): # an actor sending messages to the consumer msg = ['hello', 'world'] for s in msg: flower.send(ref, s) def publisher2(ref): msg = ['brave', 'new', 'world', ''] for s in msg: flower.send(ref, s) ref_consumer = flower.spawn(consumer) flower.spawn(publisher1, ref_consumer) flower.spawn(publisher2, ref_consumer) flower.run()
$ python examples/actor_example.py got message from 1: hello got message from 2: brave got message from 1: world got message from 2: new got message from 2: world
Flower requires Python superior to 2.6 (yes Python 3 is supported)
To install flower using pip you must make sure you have a recent version of distribute installed:
$ curl -O http://python-distribute.org/distribute_setup.py $ sudo python distribute_setup.py $ easy_install pip
For now flower can only be installed from sources. To install or upgrade to the latest released version of flower:
$ git clone https://github.com/benoitc/flower.git $ cd flower && pip install -r requirements.txt
flower is available in the public domain (see UNLICENSE). flower is also optionally available under the MIT License (see LICENSE), meant especially for jurisdictions that do not recognize public domain works.
