Create a custom Sphinx extension to document configuration values with
a simplified syntax. It is based on the `confval` but takes less space
when rendered. The extension provides:
- A `conf` directive for documenting individual configuration values
with optional type and default parameters
- A `conf` role for cross-referencing configuration values
- Automatic formatting of default values in the signature
- A custom domain that handles indexing and cross-references
For example, if we have
.. conf:: search_limit
:default: 5
We refer to this configuration option with :conf:`plugins.discogs:search_limit`.
The extension is loaded by adding the docs/extensions directory to the
Python path and registering it in the Sphinx extensions list.
