Developing

A typical development workflow is:

1. Install project requirements: pip install -r requirements.txt
2. Install additional testing requirements: pip install -r requirements-dev.txt
3. Write helpful code and tests.
4. Verify code style: ./scripts/lint.sh
5. Run test suite: pytest arviz/tests
6. Make a pull request.

There is also a Dockerfile which helps for isolating build problems and local development.

1. Install Docker for your operating system
2. Clone this repo,
3. Run ./scripts/container.sh --build

This will build a local image with the tag arviz. After building the image tests can be executing by running docker run arviz. An interactive shell can be started by running docker run -it arviz /bin/bash. The correct conda environment will be activated automatically.
