# On WSL or some flavors of linux you may need to install the `enchant`
# library in order to build the docs
sudo apt-get install -y enchant

# Install extension + test/dev/doc dependencies into your environment
python -m pip install -e .[tests,dev,docs]

# Run tests!
python -m nox -e tests-3

# skip requirements install for next time
export SKIP_REQUIREMENTS_INSTALL=1

# Build the docs, serve, and view in your web browser:
python -m nox -e docs && (cd docs/_build/html; python -m webbrowser localhost:8000; python -m http.server; cd -)
