C++20 + Lua = Flexibility

on YouTube ↗01h 33m

" summary

Shows a concrete C++20 + Lua architecture used to replace a C++98 monolith for Blu Wireless connection management, enabling live behavioral edits on trains and race cars without recompiles. Presents tooling and bindings: sol3 for fast, idiomatic C++↔Lua, SWIG type mappings: std::span std::any std::optional std::variant, plus build via CMake and benchmarks that place the Lua C API fastest, sol3 close behind, SWIG slower but multi-language. Demonstrates coroutine integration (Lua stackful vs C++20 stackless), a LuaChat example on GitHub, and real-field success.
