nameko-slackclient 0.0.3

Quick Start

Install from PyPI:

pip install nameko-slackclient

Usage

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

# config.yml

SLACK:
    TOKEN: "xoxb-abc-1232"

Or using environment variable within your config:

# config.yml

SLACK:
    TOKEN: ${SLACK_BOT_TOKEN}

More Examples

Listen for events of a particular type:

from nameko_slackclient 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:

from nameko_slackclient 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:

from nameko_slackclient 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:

from nameko_slackclient 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<ham>\w+)')
    def on_egg(self, event, message, ham=None):
        pass

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

from nameko_slackclient import rtm

class Service:

    name = 'some-service'

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

Run multiple RTM bots:

# config.yml

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

# service.py

from nameko_slackclient 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

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

Usage

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

# config.yml

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

# service.py

from nameko.rpc import rpc
from nameko_slackclient import web


class Service:

    name = 'some-service'

    slack = web.Slack()

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

You can also use multiple bots:

# config.yml

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

# service.py

from nameko.rpc import rpc
from nameko_slackclient import web


class Service:

    name = 'some-service'

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

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