Emulating the Nintendo 3DS: Generative & Declarative Programming in Action
summary
Describes a concrete system to auto-generate 3DS IPC serialization: declarative command descriptions (command id + normal/special/request/response tuples) drive template generators that produce decode/encode logic and a single GlueCommandHandler. Uses C++ features like variadic templates, if constexpr, parameter-pack expansion and constexpr tables to validate handler signatures at compile time, synthesize command blocks, and log/detect commands. Targets ~40 services with ~30 commands each, eliminates repetitive boilerplate, compiles to zero‑overhead code and works as demonstrated with live examples.
