Metamorf

A unified compiler-construction meta-language designed to define and build programming languages within a single .mor file. By describing tokens, grammar rules, semantic analysis, and code generation in one place, developers can produce native Win64 or Linux64 binaries via a built-in Zig/Clang pipeline.
