Any tutorial for embedding Clang as script interpreter into C++ Code?

c++ jit llvm clang embedded-language

I have no experience with llvm or clang, yet. From what I read clang is said to be easily embeddable Wikipedia-Clang, however, I did not find any tutorials about how to achieve this. So is it possible to provide the user of a c++ application with scripting-powers by JIT compiling and executing user-defined code at runtime? Would it be possible to call the applications own classes and methods and share objects?

edit: I'd prefer a C-like syntax for the script-languge (or even C++ itself)

I don't know of any tutorial, but there is an example C interpreter in the Clang source that might be helpful. You can find it here: http://llvm.org/viewvc/llvm-project/cfe/trunk/examples/clang-interpreter/

You probably won't have much of a choice of syntax for your scripting language if you go this route. Clang only parses C, C++, and Objective C. If you want any variations, you may have your work cut out for you.
