Hello,
We are doing a refactor of the C++ documentation which will appear in 0.12.0. Currently, the main entry point of the C++ documentation is a Doxygen-generated API documentation in the traditional format, together with a couple MarkDown pages covering some example use cases. The rewrite integrates the C++ API documentation in a larger Sphinx documentation also holding the format specification and Python docs. This allows us to add cross-references very easily and make the whole documentation more cohesive. To accompany this transformation, I have started writing some prose documentation about fundamental concepts in the C++ API. I have uploaded a snapshot build of this work-in-progress here: https://pitrou.net/arrowdevdoc/cpp/index.html Comments and suggestions are welcome. Regards Antoine.
