We have been writing a lot of python bindings for C++ code at work. Someone asked me why we need to write a lot of boilerplate code in pybind11 to create these python bindings. I personally prefer the level of configurability that pybind provides in the bindings. But it also made me think, a lot of the time my bindings are just the function name converted from CamelCase to snake_case. I went out to search for tools that automate this binding generation. I found two tools that seem to be actively maintained

1. Binder

   Binder is a tool for automatic generation of Python bindings for C++11 projects using Pybind11 and Clang LibTooling libraries. That is, Binder, takes a C++ project and compiles it into objects and functions that are all usable within Python. Binder is different from prior tools in that it handles special features new in C++11.

2. litgen

   litgen, also known as Literate Generator, is an automatic python bindings generator for humans who like nice code and APIs.
   It can be used to bind C++ libraries into documented and discoverable python modules using pybind11.
   It can also be used as C++ transformation/refactoring tool.

I haven’t tried these out but look very promising.
