[cfe-dev] clang-tidy how to exclude header from being preprocessed -- NOLINT not working

Yes. I don't want any diagnostics from 'a.h'. Simply put tidy should ignore a.h. How to do that with tidy?

Can you suggest example.
$ clag-tidy -checks="*" -header-filter=".*;-a.h", correct?

It can't not parse it. Are you asking about not issuing diagnostics from it?

I would guess as per http://clang.llvm.org/extra/clang-tidy/
you should try using -header-filter=<string>
