I think I understood why it kept failing : it is because in some line of code modified in the PR were not covered (5 or 6 in the whole code, corresponding to the specifi case that will never occur at usage). So I guess I'll just merge the PR with the red cross for the CI failed...

Yes, you are right, it is unclear. I edited my post to be (I hope) more clear

@NaveedAhmed which extension ? I have this one marketplace.visualstudio.com/items/?itemName=bbenoist.Doxyge‌​n, but is does not display correctly in VScode. Is there another extension ? I quickly looked at the list in the market, but without success yet...

This is the same problem as before : Doxygen works well, but vscode no longer recognizes the parameters

I did try that, but there it just converts this into markdown, and no longer lists the arguments in a pretty way (cf gist.github.com/user-attachments/assets/…)

thanks for your answer, it takes a little more space on the screen, but not that much, so that's good enough for me ;) (even though the possibility of having it on a single line as in my initial post would be optimal !)
