🤖 mab

mab (MAtrix Bot) is a very simple Python package that can be used to develop very simple Matrix bots. It does not aim to be the best library out there, but it aims to be convenient and usable for relatively serious projects.

✨ Features

The library supports the following features:

Completely asyncio based
Filter-based callback system
Sending images
Sending videos with automatic thumbnail generation (requires ffmpeg)

🚀 Usage

Use apt to install required system packages and pip to install the package. You may need to use root privileges to use apt. It's highly recommended you use venv or another Python virtual environment. Here are the commands to install the latest version of the library:

apt install libmagic1-dev libolm-dev
python -m pip install git+https://git.tyukalov.su/nikita/mab@v0.4.0

libmagic1-dev is needed for automatic file MIME type detection, libolm-dev is needed for E2EE to work.

Please inspect examples/image_gen_bot.py, examples/echo_bot.py or open examples/ directory to find usage examples. Examples require that you set MATRIX_HOMESERVER and MATRIX_USERNAME environment variables. Examples create session_storage directory in working directory.

🏷️ Versioning

Releases are tagged in this repository using the vX.Y.Z format. If the commit is not tagged, it must be treated as versionless and should not be used for your application.

X (Major): Breaking architectiral changes or complete rewrites. Existing code will break. Note that 0.Y.Z versions are considered very unstable, the API may change at any time and some features do not work as expected.
Y (Minor): Breaking API changes, feature removals, or behavioral modifications. Existing code will likely break.
Z (Patch): Backward-compatible feature additions, bug fixes, or internal changes. Existing code will not break.

🛠️ Development

Here's the list of commands you should execute to get started with development (including cloning the repository and installing required packages). Please note that your workflow may use something other than venv.

apt install libmagic1-dev libolm-dev
git clone https://git.tyukalov.su/nikita/mab
cd mab
python3 -m venv .venv
. .venv/bin/activate
pip install -e .
