Language bindings for C++ can be valuable tools for developers who wish to make C++ libraries available for use in other programming languages, like Python. There are many reasons developers may wish to do this, including testing, prototyping, or performance.

One of the issues often faced when writing bindings for C++ is the need to write excessive amounts of boilerplate code to bridge the gap between the C++ types and interfaces and their equivalents in other languages.

Building on previous presentations, this talk will not just explore how you can use Reflection in C++26 to generate the necessary binding code, but also how you can integrate this into a CMake-based build system to enable the automatic generation of bindings for existing classes or libraries with minimal additions. We will present real-world examples, primarily using Python, to show how language bindings can be automatically generated, but we also show how this can be extended to other languages.
