Development
Prerequisites
- Python 3.10+
make(optional — you can use plain Python commands instead)
All commands below should be run from the python/ directory:
cd python
Setup
Using Make (recommended)
All make targets automatically create a virtual environment (.venv/) and install the required dependencies — no manual setup needed.
# Install the CLI in editable mode
make install
# Install with dev tools (tests + linting)
make dev
Using Python directly
python3 -m venv .venv
source .venv/bin/activate
python -m pip install -U pip
# Install in editable mode
pip install -e .
# With dev tools
pip install -e ".[dev]"
