Differences with rendering of param and tparam attributes between versions 4.28 and 4.29

[K3WLBUDDY]

Source doxygen comment:

Output with Breathe 4.28 which seems to be the correct one:

Output with Breathe 4.29 which seems to be borked:

The same issue is observed with param doxygen tags as well with 4.29

@K3WLBUDDY If I assume Breathe 4.29.0, then this is probably because of #670. However, in screenshot of #670 you can see it renders differently with proper Template Parameters text.

Can you try latest Breathe and also post Sphinx version or try with newer Sphinx? If that doesn't work, can you add reproduction case?

hey, i'm experiencing the same issue in the c# domain

starting from 4.29.0, parameters and the return value are printed as a table without the Parameters and Return section headers. additionally, each parameter is prefixed with a Param keyword. the issue is also present in latest master branch of breathe (3023db0)

sphinx version does not seem to matter with the same rendering for 3.5.4 (highest available for breathe==4.28.0) and 4.1.2 when upgrading sphinx to latest

i've been trying different combinations of sphinx and breathe to try and narrow this down. when installing (downgrading) breathe==4.28.0, sphinx version gets dropped to 3.5.4:

sphinxcontrib-versioning==2.2.1

with that the output is rendered as expected with proper section headers and nicely formatted params (note the inline keyword still present before it was fixed)

if i force upgrade to latest sphinx, docutils and even sphinx-rtd-theme afterwards, the render is still the same as above (so fine despite dependency mismatch / error), so it seems its just the bump to breathe>4.28.0 that causes the issue

% python -m pip install docutils sphinx sphinx-rtd-theme --upgrade

This new rendering is intentional as it uses the underlying Sphinx machinery instead of custom Breathe functionality. See also #708. In short, in your theme it should be possible to add CSS to change the appearance of the field lists to get something very close to the old style. But if some extra markup is needed please reopen.
