## Motivation
If you're writing a tool that needs access to C++ AST (i.e. documentation generator, reflection library, …), you're only option apart from writing your own parser is to use [clang](https://clang.llvm.org).
It offers [three interfaces for tools](https://clang.llvm.org/docs/Tooling.html), but the only one that is designed for standalone applications is [libclang](http://clang.llvm.org/doxygen/group__CINDEX.html).
It offers [three interfaces for tools](https://clang.llvm.org/docs/Tooling.html), but the only one that really works for standalone applications is [libclang](http://clang.llvm.org/doxygen/group__CINDEX.html).
However, libclang has various limitations and does not expose the entire AST.
So there is no feasible option - except for this library.
It was originally a part of the [standardese documentation generator](http://standardese.foonathan.net), but has been extracted into an independent library.
See [this blog post](http://foonathan.net/blog/2017/04/20/cppast.html) for more information about the motiviation and design.
## Features
* Exposes (almost) all C++ entities: Supports everything from functions to classes, templates to friend declarations, macros to enums.
