My journey of fixing an unmaintained package, spanning Python, C++, nanobind and Github Actions

​DESCRIPTION

​nanobind is the official successor to the widely used pybind11 library, allowing you to quickly create seamless and maintainable Python bindings for C++ code.

​For pybind11, an extension called pybind11_json was developed to easily pass JSON objects between Python and C++. This package has been used in an open-source project that I contribute to. However, when we decided to migrate to nanobind, we discovered a major issue: the nanobind equivalent - which is even linked directly from the pybind11_json README - did not work at all.

​In this talk, I will share the fun (and not-so-fun) parts of my journey to fix this package. I'll go over what pybind11 is and how nanobind improves it. I'll provide a brief overview of the open-source project I was working on, and explain why we needed JSON interoperability. From there, I’ll dive into the specific bugs, quirks, and issues I encountered while resurrecting nanobind_json. Throughout the whole talk I will showcase necessary examples and code snippets.
