some items might be deprecated

self.client.subscribe('stream-messages', [], self.cb1)

'stream-messages' might be deprecated

looked through the hubot for what it might be now
https://github.com/RocketChat/hubot-rocketchat/blob/master/src/rocketchat_driver.coffee

seems like they use 'stream-room-messages' with a room id parameter after they determine all rooms the bot is logged into.

def callback_function(error, result):
    if error:
        print(error)
        return
    for i in result:
        print(i)
    return result

client.call("subscriptions/get", [], callback_function)

will give the subscriptions and the room ids

self.client.subscribe('stream-messages', [room id], self.cb1)

will get the messages in that room

WELLL ALMOST....
THERE IS AN UPSTREAM ISSUE with the meteor client as the first call of the subscription will normally be empty so you will get a key error.

I edited:

MeteorClient.py in sites-packages:

class CollectionData(object):
    def __init__(self):
        self.data = {}

    def add_data(self, collection, id, fields):
        if collection not in self.data:
            self.data[collection] = {}
        if not id in self.data[collection]:
            self.data[collection][id] = {}
        for key, value in fields.items():
            self.data[collection][id][key] = value

    def change_data(self, collection, id, fields, cleared):
        try:
            for key, value in fields.items():
                self.data[collection][id][key] = value

            for key in cleared:
                del self.data[collection][id][key]
        except KeyError:
            self.add_data(collection,id,fields)

    def remove_data(self, collection, id):
        del self.data[collection][id]

probably not the way you should do that but...

Then I had to comment out from the same file

#  if name in self.subscriptions:
#      raise MeteorClientException('Already subcribed to {}'.format(name))

After all of that.... here is what ended up working... someone should make all of the non hackerish corrections

Hello, thanks for your interest and sorry for the long reply.
I'll inspect a little bit what happen, this was mostly a PoC, sorry.
If you found any cool solution since, feel free to make a pull request :)
