#include header guard format?

Question

I know it makes little difference to a project but, assuming you use #defined header guards for your C++ code, what format do you use? e.g. assuming a header called f

Answer 1

I'd go with the filepath + the boost _INCLUDED suffix plus the nowadays widely supported #pragma once

In alot editors (for me its sublime) you can also define some macros/snippets for this.

Here is one that does it for you:

    
    incguard
    include guard

so yourproject/include/yourlib/yourfile.hpp

becomes YOURLIB_YOURFILE_HPP_INCLUDED

An additional external source code style checker tool could easily track consistency of your guards this way.
