DSLs, Code Generation, and New Domains for Ruby
summary
Claims that internal DSLs can generate native code for embedded and numerical work and shows two working toolchains: aren (four DSLs, ERB‑based templating, used to generate UML/ECOR and production code for BMWs) and red shift (DSL for hybrid automata that code‑generates a C extension, uses a 4th‑order Runge‑Kutta integrator, builds in <1s then loads in ~0.25s, performance near Simulink). Also describes cgen (automated C struct, accessors, marshalling, inheritance) and unmet needs: an animation DSL and an efficient packet‑handler DSL.
