Dear Haskellers,
Can GUI programming be liberated from the IO monad? Functional Reactive Programming (FRP) promises as much, and I'm trying to make this dream a reality with my [reactive-banana][] library. Having released version 0.4.0.0, I am now looking for example programs to direct the future evolution of the library.
Do you know any *small GUI programs* that you would *like* to see *implemented with Functional Reactive Programming?*
Many thanks to everyone for telling me of your examples! I have implemented a few of them: http://haskell.org/haskellwiki/Reactive-banana/Examples Overall, the library held up very well, it's already perfectly usable for implementing GUIs in the functional reactive style. I was particularly surprised that I was able implement an animation, even though the library has no notion of time yet! The CRUD/database example was the most exciting; while still somewhat messy by Haskell standards, I quite like the result. Concerning the future evolution of the library, I now have a better sense of the remaining primitive combinators that are still missing. I also added a few immediate improvements, like * MonadFix instance for NetworkDescription * Overloaded (<@) and (<@>) operators for the `apply` function and uploaded a corresponding version 0.4.1.0 on Hackage http://hackage.haskell.org/package/reactive-banana As said, the library is already very usable. In the future, I hope to implement more support for animations/audio/time; and then, only dynamic event switching will be left. Best regards, Heinrich Apfelmus -- http://apfelmus.nfshost.com
