Building the Documentation
Sphinx is tightly integrated with the Python programming language and needs
to be able to import and parse the source code to do its job. Thus, it also
needs to be able to create an appropriate python environment. This process is
If you are editing the documentation and need to regenerate the outputs as you go to see your changes reflected locally, the most reliable option is to use Tox. Tox will remove the previously generated outputs and regenerate everything from scratch:
$ tox -e docs
If you’re just working on a single page and don’t care about the entire set of documents being regenerated and linked together, you can call Sphinx directly:
$ sphinx-build -b html docs docs/_build/html
This will only update any files that have been changed since the last time the documentation was generated.
To view the documentation that’s been output at HTML, you’ll need to open the
docs/_build/html/index.html file within the PUDL repository with a web
browser. You may also be able to set up automatic previewing of the rendered
documentation in your text editor with appropriate plugins.
Some of the documentation files are dynamically generated. We use the
sphinx-apidoc utility to generate RST files from the docstrings embedded
in our source code, so you should never edit the files under
If you create a new module, the corresponding documentation file will also
need to be checked in to version control.
