[cfe-dev] Libclang and Objective-C headers

[David Chisnall]

Hi,

I'm trying to use libclang to gather information about Objective-C headers.  Unfortunately, clang appears to default to C for .h files (probably sensible) and to refer to ignore -x options passed in to clang_createTranslationUnitFromSourceFile() and clang_parseTranslationUnit().  

Is there an existing way of overriding the default language choice when parsing headers (I assume that the XCode people needed this for editing Objective-C headers?), and if so what is it?  

Alternatively, would it be possible for libclang to automatically detect the language of header files?  It's relatively easy to tell C[++] and Objective-C[++] apart (spot an #import or an @-keyword anywhere), but telling C and C++ apart is probably a bit harder.
