Rib, a language that I built that could improve the ecosystem of WASM
summary
Rib claims a small language that provides type-safe interop with WebAssembly components, with a Rust-like syntax, a REPL that autocompletes functions and arguments, and wasmtime integration via a fork. It compiles through an inference pipeline with 15+ compilation phases to a stack‑based IR, and already powers Golem OSS’s API gateway where embedded Rib scripts expose HTTP routes to durable workers. Demos show autocomplete, descriptive errors and method-call syntax working end‑to‑end while noting missing standard library pieces and imperfect error messages.
