Wrapping GTK4 in 800 lines of Clojure with Jolt
Summary
The article documents how Glimmer enables building GTK4 UIs from Clojure using Jolt FFI, keeping the UI declarative and reactive without a browser. It explains the 800-line gtk backend and the contract between the reactive core and the backend, with concrete code samples for a counter widget. It argues this approach brings web-like development ergonomics to native toolkits, offering a fast feedback loop and no C shims or bindings generators.
