abstract syntax tree - Getting AST for C++?

Question

I'm looking to get an AST for C++ that I can then parse with an external program. What programs are out there that are good for generating an AST for C++? I don't care what language it is implemented in or the output format (so long as it is readily parseable).

My overall goal is to transform a C++ unit test bed to its corresponding C# wrapper test bed.

Answer 1

You can use clang and especially libclang to parse C++ code. It's a very high quality, hand written library for lexing, parsing and compiling C++ code but it can also generate an AST.

Clang also supports C, Objective-C and Objective-C++. Clang itself is written in C++.
