I am generating documentation for a C++ project using Doxygen, doxyrest and Sphinx. For Sphinx, I'm using the Sphinx Book Theme.

I wanted to know if there exists a possibility, when accessing a macro (#define MAXIMUMSIZE 20, for example) in the Sphinx documentation, to also see its value, and not only its name. To get more precise, when I navigate to the documentation page and look for MAXIMUMSIZE, it only shows it as a #define MAXIMUMSIZE, without also providing its value (20).

Doxygen provides its value automatically. Also tried changing to Sphinx RTD Theme, but I have the same problem. I don't think this has to do with the Sphinx themes, but with Sphinx itself.

Doxygen output:

Sphinx output:

As you can see, in the second picture, 20 is missing.
