slackbotng 1.1.3

A simple chat bot for Slack

This is a fork of scrapinghub/slackbot due to the lack of the activity from the original author. Python package was renamed to slackbotng and it's being publishing to: https://pypi.org/project/slackbotng/

A chat bot for Slack inspired by llimllib/limbo and will.

Features

• Based on slack Real Time Messaging API
• Simple plugins mechanism
• Messages can be handled concurrently
• Automatically reconnect to slack when connection is lost
• Full-fledged functional tests

Installation

pip install slackbotng

Usage

Generate the slack api token

First you need to get the slack api token for your bot. You have two options:

1. If you use a bot user integration of slack, you can get the api token on the integration page.
2. If you use a real slack user, you can generate an api token on slack web api page.

Configure the bot

First create a slackbot_settings.py and a run.py in your own instance of slackbot.

Configure the api token

Then you need to configure the API_TOKEN in a python module slackbot_settings.py, which must be located in a python import path. This will be automatically imported by the bot.

slackbot_settings.py:

API_TOKEN = "<your-api-token>"

Alternatively, you can use the environment variable SLACKBOT_API_TOKEN.

Run the bot

from slackbot.bot import Bot
def main():
    bot = Bot()
    bot.run()

if __name__ == "__main__":
    main()

Configure the default answer

Add a DEFAULT_REPLY to slackbot_settings.py:

DEFAULT_REPLY = "Sorry but I didn't understand you"

Configure the docs answer

The message attribute passed to your custom plugins has an special function message.docs_reply() that will parse all the plugins available and return the Docs in each of them.

Send all tracebacks directly to a channel, private channel, or user

Set ERRORS_TO in slackbot_settings.py to the desired recipient. It can be any channel, private channel, or user. Note that the bot must already be in the channel. If a user is specified, ensure that they have sent at least one DM to the bot first.

ERRORS_TO = 'some_channel'
# or...
ERRORS_TO = 'username'

Configure the plugins

Add your plugin modules to a PLUGINS list in slackbot_settings.py:

PLUGINS = [
    'slackbot.plugins',
    'mybot.plugins',
]

Now you can talk to your bot in your slack client!

Attachment Support

from slackbot.bot import respond_to
import re
import json


@respond_to('github', re.IGNORECASE)
def github(message):
    attachments = [
    {
        'fallback': 'Fallback text',
        'author_name': 'Author',
        'author_link': 'http://www.github.com',
        'text': 'Some text',
        'color': '#59afe1'
    }]
    message.send_webapi('', json.dumps(attachments))

Create Plugins

A chat bot is meaningless unless you can extend/customize it to fit your own use cases.

To write a new plugin, simply create a function decorated by slackbot.bot.respond_to, slackbot.bot.listen_to, slackbot.bot.run_at_times:

• A function decorated with respond_to is called when a message matching the pattern is sent to the bot (direct message or @botname in a channel/group chat)
• A function decorated with listen_to is called when a message matching the pattern is sent on a channel/group chat (not directly sent to the bot)
• A function decorated with run_at_times is called periodically at a given amount of seconds

from slackbot.bot import respond_to, listen_to, run_at_times
import re

@respond_to('hi', re.IGNORECASE)
def hi(message):
    message.reply('I can understand hi or HI!')
    # react with thumb up emoji
    message.react('+1')

@respond_to('I love you')
def love(message):
    message.reply('I love you too!')

@listen_to('Can someone help me?')
def help(message):
    # Message is replied to the sender (prefixed with @user)
    message.reply('Yes, I can!')

    # Message is sent on the channel
    message.send('I can help everybody!')

    # Start a thread on the original message
    message.reply("Here's a threaded reply", in_thread=True)
    
@run_at_times(run_once_at=60)
def run_once_at_60s(client):
    client.rtm_send_message('channel_name_or_username', 'This runs once at 60s!')

To extract params from the message, you can use regular expression:

from slackbot.bot import respond_to

@respond_to('Give me (.*)')
def giveme(message, something):
    message.reply('Here is {}'.format(something))

If you would like to have a command like 'stats' and 'stats start_date end_date', you can create reg ex like so:

from slackbot.bot import respond_to
import re


@respond_to('stat$', re.IGNORECASE)
@respond_to('stat (.*) (.*)', re.IGNORECASE)
def stats(message, start_date=None, end_date=None):

And add the plugins module to PLUGINS list of slackbot settings, e.g. slackbot_settings.py:

PLUGINS = [
    'slackbot.plugins',
    'mybot.plugins',
]

The @default_reply decorator

Added in slackbot 0.4.1

Besides specifying DEFAULT_REPLY in slackbot_settings.py, you can also decorate a function with the @default_reply decorator to make it the default reply handler, which is more handy.

@default_reply
def my_default_handler(message):
    message.reply('...')

Here is another variant of the decorator:

@default_reply(r'hello.*)')
def my_default_handler(message):
    message.reply('...')

The above default handler would only handle the messages which must (1) match the specified pattern and (2) can't be handled by any other registered handler.
