:mod:`PubSubClient` --- Message bus based RPC
=============================================
This module connects to a pub/sub message bus and provices RPC functionality.
It broadcasts status messages and reacts to different messages. The client /
server for the message bus is http://gitlab.davepedu.com/dave/pymsgbus. Under
the hood, this is ZeroMQ.
Config
------
.. code-block:: json
{
"servers": ["127.0.0.1:7100"],
"subscriptions": ["pyircbot_send"],
"publish": "pyircbot_{}",
"name": "default"
}
.. cmdoption:: servers
Message bus server(s) to connect or fall back to. Currently, only use of
the first is implemented.
.. cmdoption:: subscriptions
List of bus channels to subscribe to
.. cmdoption:: publish
Publish channel name template. Will be formatted with the sub-type of
message, such as `privmsg`.
.. cmdoption:: name
Multiple bots can connect to one bus. They can be given a name to target a
single bot; all will respond to the `default` name.
Bus Messages
------------
In the format of:
.. code-block:: text
<channel name> <message body>
Bot connects to the bus:
.. code-block:: text
pyircbot_sys default online
Bot disconnects from the bus:
.. code-block:: text
pyircbot_sys default offline
Bot relaying a privmsg:
.. code-block:: text
pyircbot_privmsg default [["#clonebot"], "dave-irccloud", "message text",
{"prefix": ["dave-irccloud", "sid36094", "Clk-247B1F43.irccloud.com"]}]
User parts a channel:
.. code-block:: text
pyircbot_part default [["#clonebot"], "dave-irccloud", "part msg",
{"prefix": ["dave-irccloud", "sid36094", "Clk-247B1F43.irccloud.com"]}]
User joins a channel:
.. code-block:: text
pyircbot_join default ["dave-irccloud", "#clonebot",
{"prefix": ["dave-irccloud", "sid36094", "Clk-247B1F43.irccloud.com"]}]
User uses the command `.seen testbot`:
.. code-block:: text
pyircbot_command_seen default [["#clonebot"], "dave-irccloud", "testbot",
{"prefix": ["dave-irccloud", "sid36094", "Clk-247B1F43.irccloud.com"]}]
Client sending a message that the bot will relay
.. code-block:: text
pyircbot_send default privmsg ["#clonebot", "asdf1234"]
"""
Example Programs
----------------
Sends the content of a text file line-by-line with a delay:
.. code-block:: python
from contextlib import closing
from msgbus.client import MsgbusSubClient
import argparse
from time import sleep
from json import dumps
def main():
parser = argparse.ArgumentParser(description="send irc art")
parser.add_argument("-i", "--host", default="127.0.0.1", help="host to connect to")
parser.add_argument("-p", "--port", default=7003, help="port to connect to")
parser.add_argument("-c", "--channel", required=True, help="irc channel")
parser.add_argument("-f", "--file", required=True, help="file containing irc lines to send")
parser.add_argument("--delay", type=float, default=1.0, help="delay between lines (s)")
args = parser.parse_args()
with open(args.file) as f:
with closing(MsgbusSubClient(args.host, args.port)) as client:
for line in f:
line = line.rstrip()
print(line)
client.pub("pyircbot_send", "default privmsg {}".format(dumps([args.channel, line])))
sleep(args.delay)
if __name__ == '__main__':
main()
