A modular telegram Python bot running on python3 with an sqlalchemy database.
Note to maintainers that all schema changes will be found in the commit messages, and its their responsibility to read any new commits

Once you've setup your database and your configuration (see below) is complete, simply run:
python3 -m tg_bot
Please make sure to use python3.6, as I cannot guarantee everything will work as expected on older python versions! This is because markdown parsing is done by iterating through a dict, which are ordered by default in 3.6.
There are two possible ways of configuring your bot: a config.py file, or ENV variables.
The prefered version is to use a
config.py file, as it makes it easier to see all your settings grouped together.
This file should be placed in your
tg_bot folder, alongside the
__main__.py file .
This is where your bot token will be loaded from, as well as your database URI (if you're using a database), and most of
your other settings.
It is recommended to import sample_config and extend the Config class, as this will ensure your config contains all defaults set in the sample_config, hence making it easier to upgrade.
config.py file could be:
from tg_bot.sample_config import Config class Development(Config): OWNER_ID = 767090683 # my telegram ID OWNER_USERNAME = "iamlordutkarsh" # my telegram username API_KEY = "your bot api key" # my api key, as provided by the botfather SQLALCHEMY_DATABASE_URI = 'postgresql://username:password@localhost:5432/database' # sample db credentials MESSAGE_DUMP = '-1234567890' # some group chat that your bot is a member of USE_MESSAGE_DUMP = True SUDO_USERS =  # List of id's for users which have sudo access to the bot. LOAD =  NO_LOAD = ['translation']
If you can't have a config.py file (EG on heroku), it is also possible to use environment variables. The following env variables are supported:
ENV: Setting this to ANYTHING will enable env variables
TOKEN: Your bot token, as a string.
OWNER_ID: An integer of consisting of your owner ID
OWNER_USERNAME: Your username
DATABASE_URL: Your database URL
MESSAGE_DUMP: optional: a chat where your replied saved messages are stored, to stop people deleting their old
LOAD: Space separated list of modules you would like to load
NO_LOAD: Space separated list of modules you would like NOT to load
WEBHOOK: Setting this to ANYTHING will enable webhooks when in env mode
URL: The URL your webhook should connect to (only needed for webhook mode)
SUDO_USERS: A space separated list of user_ids which should be considered sudo users
SUPPORT_USERS: A space separated list of user_ids which should be considered support users (can gban/ungban,
WHITELIST_USERS: A space separated list of user_ids which should be considered whitelisted - they can't be banned.
DONATION_LINK: Optional: link where you would like to receive donations.
CERT_PATH: Path to your webhook certificate
PORT: Port to use for your webhooks
DEL_CMDS: Whether to delete commands from users which don't have rights to use that command
STRICT_GBAN: Enforce gbans across new groups as well as old groups. When a gbanned user talks, he will be banned.
WORKERS: Number of threads to use. 8 is the recommended (and default) amount, but your experience may vary.
Note that going crazy with more threads wont necessarily speed up your bot, given the large amount of sql data
accesses, and the way python asynchronous calls work.
BAN_STICKER: Which sticker to use when banning people.
ALLOW_EXCL: Whether to allow using exclamation marks ! for commands as well as /.
Install the necessary python dependencies by moving to the project directory and running:
pip3 install -r requirements.txt.
This will install all necessary python packages.
If you wish to use a database-dependent module (eg: locks, notes, userinfo, users, filters, welcomes), you'll need to have a database installed on your system. I use postgres, so I recommend using it for optimal compatibility.
In the case of postgres, this is how you would set up a the database on a debian/ubuntu system. Other distributions may vary.
sudo apt-get update && sudo apt-get install postgresql
sudo su - postgres
createuser -P -s -e YOUR_USER
This will be followed by you needing to input your password.
createdb -O YOUR_USER YOUR_DB_NAME
Change YOUR_USER and YOUR_DB_NAME appropriately.
psql YOUR_DB_NAME -h YOUR_HOST YOUR_USER
This will allow you to connect to your database via your terminal. By default, YOUR_HOST should be 0.0.0.0:5432.
You should now be able to build your database URI. This will be:
Replace sqldbtype with whichever db youre using (eg postgres, mysql, sqllite, etc) repeat for your username, password, hostname (localhost?), port (5432?), and db name.
The module load order can be changed via the
NO_LOAD configuration settings.
These should both represent lists.
LOAD is an empty list, all modules in
modules/ will be selected for loading by default.
NO_LOAD is not present, or is an empty list, all modules selected for loading will be loaded.
If a module is in both
NO_LOAD, the module will not be loaded -
NO_LOAD takes priority.
Creating a module has been simplified as much as possible - but do not hesitate to suggest further simplification.
All that is needed is that your .py file be in the modules folder.
To add commands, make sure to import the dispatcher via
from tg_bot import dispatcher.
You can then add commands using the usual
__help__ variable to a string describing this modules' available
commands will allow the bot to load it and add the documentation for
your module to the
/help command. Setting the
__mod_name__ variable will also allow you to use a nicer, user
friendly name for a module.
__migrate__() function is used for migrating chats - when a chat is upgraded to a supergroup, the ID changes, so
it is necessary to migrate it in the db.
__stats__() function is for retrieving module statistics, eg number of users, number of chats. This is accessed
/stats command, which is only available to the bot owner.
