Game Development Development
summary
A desktop IDE is reimplemented in Clojure with JavaFX on top of an in-memory transactional dataflow graph that turns file string refs into edges, uses Prismatic fnk for production functions, and models state changes as Datomic-like transactions. The system currently exposes 78 node types, provides undo/redo by a paper‑tape transaction log, guarantees precise forward invalidation and cache correctness during concurrent evaluation, achieves sub‑second rebuilds for live iteration, and supports live shader edit and hot‑reload into the running C++ engine.
