It's been a little while since I last wrote about Formak ( FormaK Under The Hood: Optimization for scikit-learn integration , Sat 08 October 2022). Since then, I've been busy adding functionality to FormaK and I've also been improving the tooling for the project, inspired by Boring Python: code quality. The latest piece of functionality is the C++ code generation. The PR is in progress, but the initial experiments have proved out that the generation pipeline is feasible and able to be integrated into bazel.
