How to indent c++ "special" source lines that don't end with semicolons

Question

I'm working with a system that uses special macros a lot. For instance: class UDSSLib : public UFunctionLibrary { GENERATED_BODY() void foo(); int i; }

The problem is the GENERATED_BODY() line. It's not supposed to have a semicolon after it (I guess the macro expansion has that) and I'd like to stick to that style, but as is, everything after it gets indented too far -- as statement-cont syntax rather than statement. Can I either convince the C syntax analyzer that the specific string GENERATED_BODY() is a complete statement, or else cause the line after it to be indented normally?

I had the same problem with GENERATED_BODY() from UnrealEngine and so found your question.

What works for me is to add to the buffer-local variable c-macro-names-with-semicolon and then call the function c-make-macro-with-semi-re.

For example:

(defun add-c++-macro-names-with-semicolon ()
  (add-to-list 'c-macro-names-with-semicolon "GENERATED_BODY")
  (c-make-macro-with-semi-re))
(add-hook 'c++-mode-hook 'add-c++-macro-names-with-semicolon)
