It's quite easy to use. create a channel:
from google.appengine.api import channel
token = channel.create_channel(chan_name)And start sending messages:
channel.send_message(chan_name, msg)
Unfortunately, there is neighter any non-javascript client library for use in desktop applications, nor is there any specifications of the protocol available. So I reverse-engineered the javascript-client and created a python client implementation. Feel free to use it. But be aware that although it seems to work quite well, it's not well tested yet. I've not yet used it on a real-world application. Be also aware that google could change the underlying protocol without any notice, which would obliviously break this library.
Use it like this:
import gae_channel
channel = gae_channel.Client(token='your channel token')
for msg in chan.messages():
print msg $ python receiver.py
Your channel name is: fWVwdXvNJP
now run in an other terminal:
python sender.py fWVwdXvNJP
I'm now listening for messages, dont close this terminal...
Now in another terminal, run:
$ python sender.py fWVwdXvNJP
Enter a message:test
Now you'll see the message appearing in the first terminal.
