At the end of last month I had thrown together an FFI binding [1] for Clang's 
CIndex interface with the plan of using it to bootstrap a full binding to it.  
I now wished I had push it out sooner for others to use.

I would like to use Clang's CIndex interface as a front-end to my 
LuaNativeObject [2] bindings generator, to try to simplify the bindings 
definition.

The project also include the start of a C++ to C bindings generator [3].  And 
a generic C++ parser [4] uses the CIndex interface to parse the 
class/method/member definitions from C++ code, which is used by the generator 
to create wrapper C functions for each of the public C++ methods.  Right now 
it can generate valid code that compiles, but I haven't used it for anything 
yet.  It should be easy to update the generator to also generate FFI bindings 
to the wrapped C++ interface.
