Rib, a language that I built that could improve the ecosystem of WASM (v1)
summary
Rib is a type-safe scripting language with Rust-like syntax that integrates into wasmtime (currently via a wasmtime fork) to provide REPL-driven, autocompleting calls into WebAssembly components, showing descriptive compiler errors and argument autofill. It already powers the Golem OSS API gateway, running durable worker instances and persisting state, and compiles via a configurable pipeline with 15+ compilation phases that use fixed-point type inference. Works end-to-end for single-component contexts today and aims to expand multi-component and interface disambiguation.
