Hi Jon, This is a small patch series with just two patches. The first one adds support at cdomain.py for two notations found on Sphinx 3.1: :c:expr: .. c:namespace:: With that, it should now be possible to use those two C domain tags at the media documentation, which will make it produce a decent result with both Sphinx 1.x/2.x and Sphinx 3.1+. The second patch manually changes the CEC documentation in order for it to use those macros, instead of relying at the original cdomain extensions. I tested building the docs with both Sphinx 2.4.4 and 3.2.1. They are identical, except by a minor difference: the output of :c:expr: uses a bold monospaced font with 3.1+, while it uses a non-bold monospaced font with older versions. Yet, the output looks decent on both versions. I'm planning to use the same approach on all the other documents under userspace-api/media. So, I guess it would be easier if I could merge both the cdomain.py and the media patches via the media tree, if this is ok for you. - With regards to patch 1, I tried first to use a hook at 'doctree-resolved', just like the automarkup.py, but that is too late for changing the namespace. So, I ended hooking the extra logic at 'source-read'. I suspect that this could be implemented on some other ways, but this can be optimized later on, if needed.
