PR's welcome! Dependencies are managed using uv:

• https://docs.astral.sh/uv/getting-started/installation/
• then cd into selfie-lib and run uv sync to get the dependencies

Our CI server runs three checks in the selfie-lib directory.

• uv run pytest - run tests
• uv run pyright - type checking
• uv run ruff format --check && uv run ruff check - code lint & formatting
  • uv run ruff format && uv run ruff check --fix to fix

The same setup is used for pytest-selfie and example-pytest-selfie.

For the IDE we use VSCode. Make sure to open the python directory, not the parent selfie. Recommended VSCode plugins:
