The Making of the com.lihaoyi Ecosystem
summary
A decade-old com.lihaoyi ecosystem bundles small, composable libraries that aim to be executable pseudocode while balancing high performance, type-safety and ease of use; the projects have over 10,000 GitHub stars and about 7,000,000 downloads per month. Implementation uses unusual techniques — cakes, mutable state, virtual classes, bit‑bashing and free applicatives — and admits failures (Scalatex, Scalite, Scala.Rx, Autowire, Ammonite‑Shell). Mill, the scalable Mill build tool, uses macros, generated metadata, caching and parallel execution with Chrome trace support.
