Library for creating bots for telegram with Python.

Library for creating bots for telegram with Python.

Usage example

Here goes a simple example of a bot:

from sys import argv
from time import sleep

from origamibot import OrigamiBot as Bot


class BotsCommands:
    def __init__(self, bot: Bot):  # Can initialize however you like
        self.bot = bot

    def start(self, message):   # /start command
        self.bot.send_message(message.chat.id,
            'Hello user!\nThis is an example bot.')

    def echo(self, message, value: str):  # /echo [value: str] command
        self.bot.send_message(message.chat.id, value)

    def add(self, message, a: float, b: float):   # /add [a: float] [b: float] command
        self.bot.send_message(message.chat.id, str(a + b))


if __name__ == '__main__':
    token = (argv[1]
             if len(argv) > 1 else 
             input('Enter bot token: '))
    bot = Bot(token)
    bot.add_commands(BotsCommands(bot))
    bot.start()   # start bot's threads
    while True:
        sleep(1)
        # Can also do some useful work i main thread
        # Like autoposting to channels for example

Commands are added as methods of an object(be it class or instance of it), if their names don't start with _ which makes it possible to also contain some utility functions inside command container.

For the command to be called two conditions must be met:

1. command name must match with method name
2. command's arguments must match signature of a method

Method signature supports any number of arguments with simple typing(str, int, float, bool) or without a typing(in this case all arguments are strings by default), as well as variable number of arguments *args. More complex types(as lists, tuples, custom object classes) are not supported, as bot does not know how to parse them, and I don't want to enforce my own parsing algorithm, but bot will still attempt to convert it like cls(argument), but a correct result is not guaranteed.

Boolean values are considered True if their string representation is in {'True', 'true', '1'}, and False if in {'False', 'false', '0'}

TODO

1. Add support for inline mode
