Installation

pip install karmabot

Basic Usage

After installing you can start karmabot by using the command

karmabot

However, you need to supply some settings prior to this.

Settings

By default we will look for a .karmabot file in the directory you used the karmabot command. The file should supply the following information.

KARMABOT_SLACK_USER=
KARMABOT_SLACK_TOKEN=
KARMABOT_SLACK_INVITE_USER_TOKEN=
KARMABOT_DATABASE_URL=
KARMABOT_GENERAL_CHANNEL=
KARMABOT_ADMINS=

• KARMABOT_SLACK_USER The bot's slack user id.

• KARMABOT_SLACK_TOKEN The auth toke for your bot

• KARMABOT_SLACK_INVITE_USER_TOKEN An invite token to invite the bot to new channels. Bots cannot autojoin channels, but we implemented an invite procedure for this.

• KARMABOT_DATABASE_URL The database url which should be compatible with SqlAlchemy. For the provided docker file use postgres://user42:pw42@localhost:5432/karmabot

• KARMABOT_GENERAL_CHANNEL The channel id of your main channel slack

• KARMABOT_ADMINS The slack user ids of the users that should have admin command access separated by commas.

If you do not want to use a file you have to provide environment variables with the above names. If no file is present we default to environment variables.

Development pattern for contributors

We use poetry and pyproject.toml for managing packages, dependencies and some settings.

Setup virtual environment for development

You should follow the instructions to get poetry up and running for your system. We recommend to use a UNIX-based development system (Linux, Mac, WSL). After setting up poetry you can use poetry install within the project folder to install all dependencies.

The poetry virtual environment should be available in the the project folder as .venv folder as specified in poetry.toml. This helps with .venv detection in IDEs.

Testing and linting

For testing you need to install nox separately from the project venv created by poetry. For testing just use the nox command within the project folder. You can run all the nox sessions separately if need, e.g.,

• only linting nox -rs lint
• only testing nox -rs test

For different sessions see the nox.py file. Please make sure all tests and checks pass before opening pull requests!

pre-commit

To ensure consistency you can use pre-commit. pip install pre-commit and after cloning the karmabot repo run pre-commit install within the project folder. This will enable pre-commit hooks for checking before every commit.
