1 What is it?

Reactive banana displaying trigger-happy Behavior.

Reactive-banana is a practical library for Functional Reactive Programming (FRP).

Support the project with a small donation: flattr-badge-large.png

FRP offers an elegant and concise way to express interactive programs such as graphical user interfaces, animations, computer music or robot controllers. It promises to avoid the spaghetti code that is all too common in traditional approaches to GUI programming.

The goal of the library is to provide a solid foundation.

  • Writing graphical user interfaces with FRP is made easy. The library can be hooked into any existing event-based framework like wxHaskell or Gtk2Hs. A plethora of example code helps with getting started. You can mix FRP and imperative style. If you don't know how to express functionality in terms of FRP, just temporarily switch back to the imperative style.
  • Programmers interested in the implementation of FRP will have a reference for a simple semantics with a working implementation. The library stays close to the semantics pioneered by Conal Elliott.
  • The library features an efficient implementation. No more spooky time leaks, predicting space & time usage should be straightforward.

Feedback is welcome, I want to hear from you!
