''Reactive-banana'' is a library for [[Functional Reactive Programming]] (FRP).


The goal is to create a solid foundation for anything FRP-related.
FRP offers an elegant and concise way to express interactive programs such as [http://hackage.haskell.org/package/reactive-banana-wx graphical] [https://wiki.haskell.org/Threepenny-gui user] interfaces, animations, [[Reactive-balsa|computer music]] or robot controllers. In particular, it promises to avoid the spaghetti code that is all too common in traditional approaches to GUI programming.
* Users can finally start experimenting with graphical user interfaces based on FRP since the library can be hooked into ''any'' existing event-based framework like [[wxHaskell]] or [[Gtk2Hs]], and will provide ample documentation.
 
* FRP implementors will have a reference for a simple semantics with a working implementation.
The goal of the library is to provide a solid foundation.
* No more spooky time leaks and efficiency concerns. Predicting space & time usage should be straightforward.
* Programmers interested implementing 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.
* A plethora of '''[[#documentation|example code]]''' helps with getting started.
 
The library is meant to be used in conjunction with existing libraries that are specific to your problem domain. For instance, you can hook it into ''any'' event-based GUI framework, like [[wxHaskell]] or [[Gtk2Hs]]. Several helper packages like {{HackagePackage|id=reactive-banana-wx}} provide a small amount of glue code that can make life easier.

What is it?

Reactive banana displaying trigger-happy Behavior.

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

FRP offers an elegant and concise way to express interactive programs such as graphical user interfaces, animations, computer music or robot controllers. In particular, 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.

  • Programmers interested implementing 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.
  • A plethora of example code helps with getting started.

The library is meant to be used in conjunction with existing libraries that are specific to your problem domain. For instance, you can hook it into any event-based GUI framework, like wxHaskell or Gtk2Hs. Several helper packages like reactive-banana-wx provide a small amount of glue code that can make life easier.

Feedback is welcome, I want to hear from you!
