Interfacing Lua and Ruby with C
summary
Claims that a professional C/C++ programmer can embed and script with Lua after these basics, noting Lua is ~60,000 lines and LuaJIT exists for speed. Explains bridging via the lua_State stack (push/pop, type checks, userdata, length‑prefixed strings, tables starting at one), and shows a working raw socket C wrapper used to drive network tests in manufacturing. Covers Ruby C API (VALUE, conversion macros, building .so extensions loaded with require) and practical pitfalls of memory and type marshaling.
