Hi Adam, I've been trying to make a clang-format for NuttX however I did run in some nasty bugs with clang-format. Mostly the inconsistent spacing caused by preprocessor directives (#ifdef) etc. I've filed a bug on the LLVM bugtracker (https://bugs.llvm.org/show_bug.cgi?id=44843) unfortunely I didn't get any response. Please find below the clang-format I've used, I would say it's 80% done. But it's mostly that NXStyle requires special things that clang-format doesn’t provide.
