Unravel your REPL

Paulus Esterhazy

Unravel is a new REPL client focused on human interaction. Instead of relying on nREPL, it communicates using unrepl, a simple protocol based on streams of EDN values. In this presentation, I show how unravel takes advantage of unrepl to create a rich terminal UI; how features like live documentation, auto-completion and an interactive data explorer are implemented; and finally how unravel and unrepl could help improve the overall state of Clojure tooling.

Paulus is an interactivity freak and simplicity junkie, with a strong interest in Clojure tooling. He’s co-organizer of Clojure Berlin and the maintainer of boot-react-native, boot-fmt and unravel.
