Interactive Metaprogramming Shell based on Clang
summary
An interactive C++ metaprogramming shell based on Clang exposes actual template execution: a patched Clang (templight) emits a template instantiation trace that a debugger replays, giving forward/back traces, breakpoints and GDB‑like stepping. The project implements meta shell plus an MDB debugger, supports include paths and environment reloads, evaluates boxed integers/booleans, and demonstrates Fibonacci and factorial metaprograms interactively. The tools work live (online demo and installers exist) and reveal concrete instantiation order and types rather than vague examples.
