Dear list, the Show class is extremely useful for exploring Haskell in a terminal, but sometimes, I just want something fancier. For instance, I'm currently dabbling with sound generation and it is only natural that I want to hear the sound instead of seeing a textual representation. Another example would be graphics, that are simply drawn on screen whenever you evaluate their value. Of course, this is simple to implement with a class class Demonstrable a where demo :: a -> IO () instance Demonstrable Sound where demo = play instance Demonstrable Sound where demo = draw instance Demonstrable GUI where demo = run etc. However, I don't want to reinvent the wheel, small as it may be, hence my question: is there a package on hackage that already defines a class similar to Demonstrable ? Or any other projects in this direction, like, say, a fancy REPL built on wxHaskell? Best regards, Heinrich Apfelmus -- http://apfelmus.nfshost.com
Does this mean we're going to see music FRP examples soon?!

Dear list,

Of course, this is simple to implement with a class
class Demonstrable a where demo :: a -> IO ()
instance Demonstrable Sound where demo = play instance Demonstrable Sound where demo = draw instance Demonstrable GUI where demo = run etc.
However, I don't want to reinvent the wheel, small as it may be, hence my question: is there a package on hackage that already defines a class similar to Demonstrable ? Or any other projects in this direction, like, say, a fancy REPL built on wxHaskell?

I'm not so sure about the "soon" part, but yes, using FRP to make music is part of the plan. Best regards, Heinrich Apfelmus -- http://apfelmus.nfshost.com

haskell skillz if i want to do some sound synthesis, i think it would be
really spiffy to work on something like that! are you working on this
privately or do you have a public repo one can clone? a fully-haskell
sound synth program would be really spiffy!! (esp if one could code new
synths in real-time in haskell....)

Folks have been doing sound synthesis in Haskell for a long time; in particular, I'm currently building on Rohan Drape's bindings to SuperCollider http://slavepianos.org/rd/ut/hsc3-texts/hsc3-tutorial.html There's also Henning Thielemann who managed to do real-time audio editing in Haskell by performing run-time compilation with LLVM http://hackage.haskell.org/package/synthesizer Still, I think there's a need (I certainly have it) for a simple-to-use package that makes it really easy to play with sound synthesis in Haskell, i.e. that supports instant gratification. I'm currently working on a project called 'tomato-rubato' that aims to do precisely that. I'll put up a github repo once I have something that is glued together by duct tape rather than spit.
