The docs for rules_python are generated using a combination of Sphinx, Bazel, and Readthedocs.org. The Markdown files in source control are unlikely to render properly without the Sphinx processing step because they rely on Sphinx and MyST-specific Markdown functionality.
The actual sources that Sphinx consumes are in this directory, with Stardoc generating additional sources or Sphinx.
Manually building the docs isn't necessary -- readthedocs.org will automatically build and deploy them when commits are pushed to the repo.
Generating docs for development is a two-part process: starting a local HTTP server to serve the generated HTML, and re-generating the HTML when sources change. The quick start is:
bazel run //docs:docs.serve # Run in separate terminal ibazel build //docs:docs # Automatically rebuilds docs
This will build the docs and start a local webserver at http://localhost:8000 where you can view the output. As you edit files, ibazel will detect the file changes and re-run the build process, and you can simply refresh your browser to see the changes. Using ibazel is not required; you can manually run the equivalent bazel command if desired.
The ibazel tool can be used to automatically rebuild the docs as you development them. See the ibazel docs for how to install it. The quick start for linux is:
sudo apt install npm sudo npm install -g @bazel/ibazel
Sphinx is configured to parse Markdown files using MyST, which is a more advanced flavor of Markdown that supports most features of restructured text and integrates with Sphinx functionality such as automatic cross references, creating indexes, and using concise markup to generate rich documentation.
MyST features and behaviors are controlled by the Sphinx configuration file, docs/conf.py. For more info, see https://myst-parser.readthedocs.io.
The Sphinx-specific configuration files and input doc files live in docs/.
The Sphinx configuration is docs/conf.py. See https://www.sphinx-doc.org/ for details about the configuration file.
There's two basic parts to the readthedocs configuration:
.readthedocs.yaml: This configuration file controls most settings, such as the OS version used to build, Python version, dependencies, what Bazel commands to run, etc.For more readthedocs configuration details, see docs.readthedocs.io.
