Automatic C++ source code generation with clang
summary
Shows how to write a custom C++ source-generation tool using clang 3.9 and its libTooling library to analyze existing code and emit new C++ (examples include enum-to-string converters). Covers building the tool from scratch: argument handling, invoking clang, walking the AST to find targets, producing generated code, and integrating the tool into a CMake build. Uses simple, concrete examples to illustrate the approach.
