===========================
Slack Extensions for Nameko
===========================

`Nameko`_ extension for interaction with `Slack APIs`_. Uses
`Slack Developer Kit for Python`_.

.. _Nameko: http://nameko.readthedocs.org
.. _Slack APIs: https://api.slack.com
.. _Slack Developer Kit for Python: http://slackapi.github.io/python-slackclient

Real Time Messaging Client
==========================

The RTM extension is a Websocket client for Slack's `Real Time Messaging API`_
that allows you to receive events from Slack in real time. The ``rtm`` module
contains two Nameko entrypoints for handling such events - ``handle_event`` and
``handle_message``.

.. _Real Time Messaging API: https://api.slack.com/rtm

Usage
-----

Provide Slack bot API token in your Nameko service config file:

.. code:: yaml

# config.yml

SLACK:
TOKEN: "xoxb-abc-1232"

Or using environment variable within your config:

.. code:: yaml

# config.yml

SLACK:
TOKEN: ${SLACK_BOT_TOKEN}

Define your service with an entrypoint which will listen for and fire on any
event coming from Slack:

.. code:: python

# service.py

from nameko_slack import rtm

class Service:

name = 'some-service'

@rtm.handle_event
def on_any_event(self, event):
print(event)

Finally, run the service:

.. code::

$ SLACK_BOT_TOKEN=xoxb-abc-1232 nameko run --config ./config.yaml service
starting services: some-service
{'type': 'hello'}
{'type': 'presence_change', 'user': 'ABCDE1234', 'presence': 'active'}
{'type': 'user_typing', 'user': 'ABCDE1234', 'channel': 'ABCDE1234'}
{'type': 'message', 'text': 'spam', 'channel': 'ABCDE1234', 'user': 'ABC...
{'type': 'presence_change', 'user': 'ABCDE1234', 'presence': 'active'}
...

More Examples
-------------

Listen for events of a particular type:

.. code:: python

from nameko_slack import rtm

class Service:

name = 'some-service'

@rtm.handle_event('presence_change')
def on_presence_change(self, event):
pass

Listen for any message type event:

.. code:: python

from nameko_slack import rtm

class Service:

name = 'some-service'

@rtm.handle_message
def on_any_message(self, event, message):
pass

Use regular expressions to fire on matching messages only:

.. code:: python

from nameko_slack import rtm

class Service:

name = 'some-service'

@rtm.handle_message('^spam')
def on_message_starting_with(self, event, message):
pass

Parse message and pass matching groups as positional or named arguments
to the entrypoint:

.. code:: python

from nameko_slack import rtm

class Service:

name = 'some-service'

@rtm.handle_message('^spam (\w*)')
def on_spam(self, event, message, egg):
pass

@rtm.handle_message('^egg (?P\w+)')
def on_egg(self, event, message, ham=None):
pass

Respond back to the channel by returning a string in the message handling
entrypoint:

.. code:: python

from nameko_slack import rtm

class Service:

name = 'some-service'

@rtm.handle_message
def sure(self, event, message):
return 'sure, {}'.format(message)

Run multiple RTM bots:

.. code:: yaml

# config.yml

SLACK:
BOTS:
alice: ${ALICE_BOT_TOKEN}
bob: ${BOB_BOT_TOKEN}

.. code:: python

# service.py

from nameko_slack import rtm

class Service:

name = 'some-service'

@rtm.handle_message(bot_name='alice')
def listen_as_alice(self, event, message):
pass

@rtm.handle_message(bot_name='bob')
def listen_as_bob(self, event, message):
pass

.. code::

$ ALICE_BOT_TOKEN=xoxb-aaa-111 BOB_BOT_TOKEN=xoxb-bbb-222 nameko run --config ./config.yaml service
starting services: some-service

WEB API Client
==============

A simple dependency provider wrapping `Slack WEB API client`_.

.. _Slack WEB API client: http://slackapi.github.io/python-slackclient/basic_usage.html#sending-a-message

Usage
-----

The dependency provider uses the same config key as the RTM extension:

.. code:: yaml

# config.yml

AMQP_URI: 'pyamqp://guest:guest@localhost'
SLACK:
TOKEN: ${SLACK_BOT_TOKEN}

.. code:: python

# service.py

from nameko.rpc import rpc
from nameko_slack import web

class Service:

name = 'some-service'

slack = web.Slack()

@rpc
def say_hello(self, name):
self.slack.api_call(
'chat.postMessage',
channel="#nameko",
text="Hello from Nameko! :tada:")

You can also use multiple bots:

.. code:: yaml

# config.yml

AMQP_URI: 'pyamqp://guest:guest@localhost'
SLACK:
BOTS:
alice: ${ALICE_BOT_TOKEN}
bob: ${BOB_BOT_TOKEN}

.. code:: python

# service.py

from nameko.rpc import rpc
from nameko_slack import web

class Service:

name = 'some-service'

alice = web.Slack('alice')
bob = web.Slack('bob')

@rpc
def say_hello(self):
self.alice.api_call(
'chat.postMessage',
channel="#nameko",
text="Hello from Alice! :tada:")
self.bob.api_call(
'chat.postMessage',
channel="#nameko",
text="Hello from Bob! :tada:")
