Hi Ryan,

This looks great. I'd like to use the opportunity to point out ffi-gen, a similar project which grew out of the ruby-llvm project, and is used to generate the LLVM ffi for ruby-llvm. Its test cases include Cairo, Clang itself, OpenGL, Sqlite3 and others.

These projects seem subtly different in scope–ffi-gen implements Clang bindings itself and only has a Ruby backend, but there may be some opportunity to share code or techniques.

Cheers,

For anyone interested, I've recently been working on c2ffi (https://github.com/rpav/c2ffi), which uses Clang to parse C into JSON, and I have just posted c2ffi-ruby, which transforms the JSON into a file for ruby-ffi:

    https://github.com/rpav/c2ffi-ruby

This should produce more accurate input than SWIG.

Apologies for ugly code; this was done as a bit of a test for c2ffi, and I haven't written much ruby in awhile.  Nor has it been extensively tested, but it does parse the included Cairo bindings.
