So the instructions below are for setting up the development environment for Breeze +using `uv`. However we are using only standard python packaging tools, so you can still use `pip` or +`pipenv` or other build frontends to install Breeze, but we recommend using `uv` as it is the most +convenient way to install, manage python packages and virtual environments. + +Unlike in Airflow, where we manage our own constraints, we use `uv` to manage requirements for Breeze +and we use `uv` to lock the dependencies. This way we can ensure that the dependencies are always +up-to-date and that the development environment is always consistent for different people. This is +why Breeze's `uv.lock` is committed to the repository and is used to install the dependencies by +default by Breeze. + +1. Install `uv` - see [uv documentation](https://docs.astral.sh/uv/getting-started/installation/) +2. Create a new virtual environment for Breeze development: + +```shell +uv venv +``` + +3. Synchronize Breeze dependencies with `uv` to the latest dependencies stored in uv.lock file: + +```shell +uv sync +``` + Review Comment: Worth adding extra example otherwise it won't have pytest installed ``` uv sync --extra devel ``` -- This is an automated message from the Apache Git Service.
