MultiBot
========

|license| |project_version| |python_version|

Platform agnostic high-level bot infrastructure. Develop one bot and you will have three: one for Discord, another one for Telegram and another one for Twitch. All bots use the same objects and logic.

For now there are adapters for three platforms but more may be added in the future.

|

Installation
------------

Python 3.10 or higher is required.

.. code-block::

    pip install multibot

|

Quick start
-----------

Discord
~~~~~~~

You will need create an discord application at https://discord.com/developers/applications and generate a **BOT_TOKEN** for your bot.

You will have to select the **bot** and **applications.commands** scopes and the **Administrator** permission. And as for the Discord Intents (in the Bot/Build-A-Bot panel) you must activate **PRESENCE INTENT**, **SERVER MEMBERS INTENT** and **MESSAGE CONTENT INTENT**.

.. code-block:: python

    import os

    from multibot import DiscordBot, Message

    discord_bot = DiscordBot(os.environ['DISCORD_BOT_TOKEN'])


    @discord_bot.register('hello')
    async def function_name_1(message: Message):
        await discord_bot.send('Hi!', message)


    discord_bot.start()

|

Telegram
~~~~~~~~

You will need your own **API_ID** and **API_HASH**. To get them see `Native Telegram app & MTProto configuration`_.

The first time you start the bot you will need a **BOT_TOKEN** (then you can save and reuse the session). To get your **BOT_TOKEN** you will need to talk to BotFather_.

Other configurations with BotFather_:
 - Deactivate the privacy mode to read group messages or add your bot as an administrator.
 - Activate the inline mode if you want to use it.

.. code-block:: python

    import os

    from multibot import Message, TelegramBot

    telegram_bot = TelegramBot(
        api_id=os.environ['TELEGRAM_API_ID'],
        api_hash=os.environ['TELEGRAM_API_HASH'],
        bot_token=os.environ['TELEGRAM_BOT_TOKEN']
    )


    @telegram_bot.register('hello')
    async def function_name_1(message: Message):
        await telegram_bot.send('Hi!', message)


    telegram_bot.start()

The session will be saved locally using SQLite.

|

You can save the session data in a string (string session). This serves to facilitate the use of sessions when hosting the application in cloud services with ephemeral file systems. Just change the :code:`.start()` line to the following:

.. code-block:: python

    # telegram_bot.start()
    print(telegram_bot.string_sessions)

This will print a dictionary with the bot sessions to the console:

.. code-block:: python

    {
        'bot_session': '................',
        'user_session': None
    }

|

If you have a string session you can provide it instead of the bot token:

.. code-block:: python

    telegram_bot = TelegramBot(
        api_id=os.environ['TELEGRAM_API_ID'],
        api_hash=os.environ['TELEGRAM_API_HASH'],
        bot_session=os.environ['TELEGRAM_BOT_SESSION']  # <----- instead of bot_token
    )

|

Adding an user bot
..................

You can add a user bot to your telegram bot to extend certain functionalities such as accessing the message history (useful if you have not been registering the messages in a database or similar), accessing the user's contacts to make whitelists, etc.

.. code-block:: python

    telegram_bot = TelegramBot(
        api_id=os.environ['TELEGRAM_API_ID'],
        api_hash=os.environ['TELEGRAM_API_HASH'],
        bot_session=os.environ['TELEGRAM_BOT_SESSION'],
        phone='+00123456789'
    )

|

Or provide an user string session instead of phone:

.. code-block:: python

    telegram_bot = TelegramBot(
        api_id=os.environ['TELEGRAM_API_ID'],
        api_hash=os.environ['TELEGRAM_API_HASH'],
        bot_session=os.environ['TELEGRAM_BOT_SESSION'],
        user_session=os.environ['TELEGRAM_USER_SESSION'],
    )

|

Twitch
~~~~~~

You will need your own **BOT_TOKEN** which you can generate on: https://twitchapps.com/tmi/. For more information see https://dev.twitch.tv/docs/irc.

.. code-block:: python

    import os

    from multibot import Message, TwitchBot

    twitch_bot = TwitchBot(
        token=os.environ['TWITCH_ACCESS_TOKEN'],
        initial_channels=['channel_name'],  # Optional. You can later make the bot join a chat with join() method
        owner_name='owner_name'  # Optional. So the bot knows who to respect. Although keep in mind that the streamer cannot be punished
    )


    @twitch_bot.register('hello')
    async def function_name_1(message: Message):
        await twitch_bot.send('Hi!', message)


    twitch_bot.start()

|

Database (optional)
-------------------

The entire library is ready to be easily configured to use your MongoDB_ database. It will automatically record all the information handled by the bot: messages, chats, users, etc.

To use a MongoDB_ database, just add environment variables:
 - :code:`DATABASE_NAME` (required)
 - :code:`MONGO_HOST` (optional. Defaults to :code:`'localhost'`)
 - :code:`MONGO_PORT` (optional. Defaults to :code:`27017`)
 - :code:`MONGO_USER` (optional)
 - :code:`MONGO_PASSWORD` (optional)

|

Extended guide
--------------

How the bot works
~~~~~~~~~~~~~~~~~

The bot works by registering functions that will be executed later when the user provides an input message that meets the requirements specified in the arguments of :code:`Multibot.register()`.

Each function you have registered in the bot will receive a :code:`Message` object that contains all the necessary information related to the context of said message.

Ways to design your bot
~~~~~~~~~~~~~~~~~~~~~~~

For the examples we are going to use the TelegramBot. But remember that all bots work the same since they use the same objects and logic. "They speak the same language".

Buttons
~~~~~~~

Add buttons to the messages you send with your bot, specify a key, and register that key to a method with :code:`Multibot.register_button()`. In this way, when a user presses a button associated with a key, the bot infrastructure will know which callbacks to call.

You can register multiple methods for the same key, as well as one method for multiple keys.

Annex
-----

Native Telegram app & MTProto configuration
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

TelegramBot connects directly to Telegram servers using its own protocol (MTProto), so you are not limited by the http bots api. Anything you can do with the official mobile app, desktop or web is possible with this bot.

MTProto also allows the creation of user bots, bots that automate tasks with your own human account for which you would need to create a new session as when you open a session for the first time on a new device. Keep in mind that you will be asked for the security code that Telegram sends you by private chat when someone wants to log in with your account.

For both a normal bot and a user bot (bot using your "human" account) you will need the **API_ID** and **API_HASH**. To get them you will have to go to https://my.telegram.org, log in and create an app.

    **WARNING!**
        The **my.telegram.org** security code is **NOT** like a session code, do not give it to anyone, it is only to enter this website. If you have doubts: the code that :code:`MultiBot.TelegramBot` may ask you for is **NOT** the same. :code:`MultiBot.TelegramBot` would only need a different code in case of a new session when you run it for the first time.
