Sphinx theme for Airflow

Sphinx theme for Apache Airflow documentation.

Install from sources

In order to start working with the theme, please follow the instructions below.

Make sure your python shell command executes Python3 interpreter. If necessary, use a virtual environment:
```
mkvirtualenv -p python3 <name_of_environment>
```
To make Javascript and CSS code available for the theme, run the following command in the root directory:
```
./site.sh build-site && ./site.sh prepare-theme
```
To install the required Python packages, in <ROOT DIRECTORY>/sphinx_airflow_theme run:
```
pip install -e .
```
To launch the demo documentation page, in <ROOT DIRECTORY>/sphinx_airflow_theme/demo run:
```
./docs.sh build && ./docs.sh preview
```

Generate Airflow documentation with Sphinx theme changes

If you made some modifications to Sphinx theme and want to generate Airflow documentation to check the end results, please follow these steps:

In airflow-site repository, build Airflow website:
```
./site.sh build-site
```

Package the Sphinx theme in a whl file:

cd ./sphinx_airflow_theme
python3 setup.py sdist bdist_wheel

(Optional) Double-check your modifications to the Sphinx theme are in the whl file:
```
pip install wheel
wheel unpack ./sphinx_airflow_theme-0.0.11-py3-none-any.whl
```

Copy the whl file to files directory in airflow repository:

cp ./sphinx_airflow_theme-0.0.11-py3-none-any.whl ${AIRFLOW_REPO}/files/

In airflow repository, initiate a new breeze environment:
```
breeze
```

In the breeze container, generate the documentation after installing the theme:

pip install /files/sphinx_airflow_theme-0.0.11-py3-none-any.whl --force-reinstall
# Generate Airflow documentation only. If you need to generate the whole documentation (all providers),
# you can do it using `/opt/airflow/scripts/in_container/run_docs_build.sh`. It takes longer to execute.
/opt/airflow/scripts/in_container/run_docs_build.sh --package-filter apache-airflow

Verify the documentation generated is correct and includes your modifications. The documentation is generated in docs/_build/docs/. If you generated Airflow documentation only, you can check the results in docs/_build/docs/apache-airflow/latest/.

Install developer version

To install the latest development version of a theme, run:

THEME_VERSION="$(curl -s https://api.github.com/repos/apache/airflow-site/releases/latest | grep '"tag_name":' | cut -d '"' -f 4)"
pip install "https://github.com/apache/airflow-site/releases/download/${THEME_VERSION}/sphinx_airflow_theme-${THEME_VERSION}-py3-none-any.whl"
