wtf is ffpython?

ffpython is a tool that lets C++ programs and Python scripts talk to each other easily. If you have a C++ application and want to let it run Python code, or if you want to give Python access to fast C++ functions and objects, this library handles the messy translation work for you. The library works in two directions. First, a C++ program can reach into Python: it can read or change Python variables, and it can call Python functions, passing in numbers, text, and lists of data. Second, a C++ developer can register their own C++ functions and classes so that Python code can use them directly. Once a C++ class is registered, Python treats it like a native Python object, creating instances, calling methods, and even inheriting from it. C++ objects can also be passed into Python and manipulated there. When Python encounters an error, the library catches it and hands it back to C++ with a clear explanation of what went wrong. This would appeal to a game developer or a startup founder building a performance-critical application in C++ who wants to add scripting or plugin support. For example, a game engine written in C++ could expose its internals to Python so that level designers can write game logic in a simpler, faster-to-iterate language. A data analytics product could also let users write Python scripts that call into a C++ backend for heavy computation. What stands out is the simplicity of the setup. The entire library is contained in a single C++ header file, meaning you just drop it into your project and it works, no complex build configuration needed. It is also a thin wrapper around Python's own underlying API, so it adds very little overhead. One limitation to note: it currently supports Python 2.x across Windows and Linux, while Python 3 support is still being worked on, since the Python 3 API changed significantly between minor versions.
