RukaLang
RukaLang is an experimental language and compiler designed to be simple, understandable, fast, and safe. It uses mutable value semantics to provide memory safety without a garbage collector or the awkwardness of dealing with persistent datastructures, and it has (well, will have) an easy-to-understand metaprogramming system based on MetaOCaml that won't require learning a bunch of additional syntax.
What You Can Explore Here
The playground compiles programs in-browser and displays intermediate representations (AST/HIR/MIR), generated Rust, generated WAT (WebAssembly's text format), so language and compiler behavior are visible from source text all the way down to emitted artifacts.
Design and Validation
The docs and rustdoc sections document language semantics, compiler architecture, and API surfaces. They are designed to keep language decisions, implementation details, and developer workflows discoverable from one place.
