It looks like gcc and clang differ on whether they accept this code. Pasting the contents of the "reproduction code" into a file named `test.c`, `gcc -c -std=c23 test.c` succeeds...

I think this suggests that clangd is processing your header file as a C++ file (and then the log message is saying that it can't apply your `.clang-format` because your...

As documented at https://clangd.llvm.org/features#experimental-c20-modules-support, Modules support is experimental and behind a flag. Please try using a recent clangd version (modules support first appeared in clangd 19, but a lot of...

If you're referring to the class name not being printed in the signature help popup, that's intentional to keep the length of the popup contents manageable. The contents of the...
