Will Jones ed6be12ad6 docs: clear the mkdocs warning backlog so --strict passes
`mkdocs build` emitted 61 warnings on main, and rendering the previously
undocumented classes in this PR pushed that to 158. That backlog is what
blocks turning on strict mode (#3707), so clear it here rather than leave
it worse than we found it.

Most of it was one systematic false positive: griffe cannot see the
generated `__init__` of a pydantic dataclass, so every documented
parameter looked unknown. `warn_unknown_params` turns that check off.

The rest were real docstring bugs, in 15 docstrings:

* Prose trailing a `Parameters` section is read as parameter names, which
  invented parameters called `The`, `you` and `To`. Moved into `Notes` or
  the summary.
* numpydoc only reads a type when the colon has spaces around it. Where
  the documented name is a pydantic attribute rather than a signature
  parameter, griffe has no signature to fall back on and the type was
  dropped. Affects nine embedding classes.
* `num_partitions, default sqrt(num_rows)` and friends parse as a list of
  names, rendering a bogus `default` parameter.
* One parameter indented five spaces instead of four.

`nodejs/CONTRIBUTING.md` links to the repo-root CONTRIBUTING.md, which
does not resolve once typedoc copies the file into `docs/src/js/_media/`;
an absolute URL works from both places.

`mkdocs build --strict` now exits 0.

LanceDB Documentation

LanceDB docs are available at docs.lancedb.com.

The SDK docs are built and deployed automatically by Github Actions whenever a commit is pushed to the main branch. So it is possible for the docs to show unreleased features.

Building the docs

Setup

  1. Install LanceDB Python. See setup in Python contributing guide. Run make develop to install the Python package.
  2. Install documentation dependencies. From LanceDB repo root: pip install -r docs/requirements.txt

Preview the docs

cd docs
mkdocs serve

If you want to just generate the HTML files:

PYTHONPATH=. mkdocs build -f docs/mkdocs.yml

If successful, you should see a docs/site directory that you can verify locally.

Adding examples

To make sure examples are correct, we put examples in test files so they can be run as part of our test suites.

You can see the tests are at:

  • Python: python/python/tests/docs
  • Typescript: nodejs/examples/

Checking python examples

cd python
pytest -vv python/tests/docs

Checking typescript examples

The @lancedb/lancedb package must be built before running the tests:

pushd nodejs
npm ci
npm run build
popd

Then you can run the examples by going to the nodejs/examples directory and running the tests like a normal npm package:

pushd nodejs/examples
npm ci
npm test
popd

API documentation

Python

The Python API documentation is organized based on the file docs/src/python/python.md. We manually add entries there so we can control the organization of the reference page. However, this means any new types must be manually added to the file. No additional steps are needed to generate the API documentation.

Typescript

The typescript API documentation is generated from the typescript source code using typedoc.

When new APIs are added, you must manually re-run the typedoc command to update the API documentation. The new files should be checked into the repository.

pushd nodejs
npm run docs
popd
