I'm currently working on implementing proper tooltips for macro definitions
and expansions in KDevelop. There, I'd like to show both the macro definition
body and (if hovering a macro expansion) the expanded macro body.
I can easily retrieve the body for macro definitions using clang_tokenize on
the definition's extent, but that won't work for macro *expansions*, because I
only get the token stream *before* the preprocessing happened.
So, am I completely missing something or is this feature just not exposed in
libclang? If not exposed, can someone point me to the correct location in the
C++ API where to retrieve that information?
