Sphinx extension for ESPHome documentation.
Raw
esphome-sphinx.py
"""
ESPHome Sphinx Extension.
This extension provides ESPHome documentation specific. While it may be a good starting
point for other projects, the esoteric nature of the included code is designed to assist
in automating the linking and indexing of components, devices, and blueprints.
Because Sphinx internals are foreign to most people looking through this, the documentation
in this file will verbose. (Future me thanks you for leaving them here too.)
Quick and dirty usage guide:
* Component support:
* Definition: `.. esphome::component-definition::`
* Reference: `:esphome:component:`component-category:component-alias``
* Index: `.. esphome:index:: Components`
* Device support:
* Definition: `.. esphome::device-definition::`
* Reference: `:esphome:device:`device-category:device-alias``
* Index: `.. esphome:index:: Devices`
* Cookbook support:
* Definition: `.. esphome::cookbook-entry::`
* Reference: `:esphome:recipe:`ble-itag``
* Index: `.. esphome:index:: Cookbook`
Further notes:
* `sphinx.addnodes.pending_xref` doesn't quite solve the problem due to domain data;
* TOC image parsing is limited to things in /images/<name>.
