Building a Modern Ruby ＜-＞ C++ Toolchain
summary
Modernized Rice adds C++11+ templates, STL support, ownership semantics and buffer/pointer handling, FFI‑Clang parses headers into an AST and RubyBindGen auto‑generates Rice or FFI glue plus CMake projects, and RubyGems now understands modern CMake. Result: a working OpenCV Ruby gem with ~1,158 classes, ~10,000 methods, 160 enums and ~1,000 fields, a ported test suite, and live demos (webcam face detection, filters and a neural‑net person detector). Builds compile and pass the added unit tests.
