A plug-in based telegram bot

It is recommended to use a virtualenv for Skybeard. Create and activate the virtual environment with

virtualenv venv
source venv/bin/activate

then install the base requirements with

pip install -r requirements.txt

You will then need to make a config.py. An example config.py is provided so you can simply:

cp config.py.example config.py

To run skybeard define your key in the environment variable $TG_BOT_TOKEN or as an argument with -k and run main.py. this can be done easily e.g.:

./main.py -k 99121185:RUE-UAa7dsEaagAKkysPDjqa2X7KxX48e 

Skybeard source documentation: http://skybeard-2.readthedocs.io/en/latest/ Skybeard wears many beards. The bot will automatically load any "beard" (a plug-in) that is placed in the beards folder. Beards are typically structured like so:

beards
|
|___myBeard
    |    __init__.py
    |    config.py
    |    requirements.txt
    |    ...
    |
    |___docs
        |    README
        |    ...

In this example the myBeard folder containts a requirements.txt for any additonal dependencies so they can be pipped, a config.py file for configuration of the beard and settings and the __init__.py which contains the class that that is the interface between the plug-in and skybeard. This interface class inherits from skybeard.beards.BeardChatHandlerwhich handles the mounting of the plug-in, registering of commands etc, and also thetelepot.aio.helper.ChatHandler`.

The folder can also contain any other python modules and files that are needed for the plugin.

Creating a new beard requires knowledge of the telepot telegram API, see: http://telepot.readthedocs.io/en/latest/

An example async plug-in that would echo the user's message would look like this:

import telepot
import telepot.aio
from skybeard.beards import BeardChatHandler


class EchoPlugin(BeardChatHandler):
    
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        #register command "/hello" to dispatch to self.say_hello()
        self.register_command("hello", self.say_hello)
    
    #is called when "/hello" is sent
    async def say_hello(self, msg):
        name = msg['from']['first_name']
        await self.sender.sendMessage('Hello {}!'.format(name))
    
    #is called every time a message is sent
    async def on_chat_message(self, msg):
        text = msg['text']
        await self.sender.sendMessage(text)
        await super().on_chat_message(msg)

This plug-in will greet the user when they send "/hello" to Skybeard by using the register_command() method of the BeardChatHandler and will also echo back any text the user sends by overwriting the on_chat_message() method (and calling the base method with super() afterwards).

See the examples folder for examples of callback functionality, timers, and regex predication.
