Rebuild the documentation

Official rebuilds

The documentation is rebuild on every release of lvgl (first and third Tuesday of every month).

Build locally

The following directions are given for Ubuntu, but should also be useful as a general guide. They assume that https://github.com/lvgl/lvgl is cloned in a folder named lvgl, and https://github.com/lvgl/docs is beside it in another folder named docs. The paths are not important (both folders can be located anywhere) but you may have to adjust these instructions slightly.

To rebuild the API documentation, you need Doxygen.

$ ls .
docs lvgl
$ sudo apt install doxygen
$ cd lvgl/scripts
$ doxygen Doxyfile

The documentation is compiled into HTML or another form using Sphinx. In order to get started Sphinx and some other components need to be installed on your system.

$ ls .
docs lvgl
$ pip install -U sphinx recommonmark commonmark breathe sphinx-rtd-theme
$ cd docs # IMPORTANT: note the two .. paths. The lvgl folder also has a folder inside it named docs.
$ rm xml/*
$ cp -a ../lvgl/docs/api_doc/xml/* xml/
$ cd en
$ make html
The HTML pages are in _build/html.
