Yampa is a domain-specific embedded language for the programming of hybrid (discrete and continious) systems using the concepts of Functional Reactive Programming (FRP). Yampa is structured using Arrows, which greatly reduce the chance of introducing space- and time-leaks into reactive, time-varying systems.
Yampa was originally developed by the Yale Haskell Group.
