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

Question

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)

Answer 1

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.

Answer 2

I don't know about Clang but you might want to look at Ch:

This is described as an embeddable or stand-alone c/c++ interpreter. There is a Dr. Dobbs article with examples of embedding it here:

I haven't done more than play with it but it seems to be a stable and mature product. It's commercial, closed-source, but the "standard" version is described as free for both personal and commercial use. However, looking at the license it seems that "commercial" may only include internal company use, not embedding in a product that is then sold or distributed. (I'm not a lawyer, so clearly one should check with SoftIntegration to be certain of the license terms.)
