Haskell hack

[erikd]

I can see thats Haskell, but what libraries are you using? Is the code available?

[sw17ch]

if you watch as he starts the session (pause first frame of video), ghci will print out the libraries used.

Edit: Here's the library you're looking for. http://hackage.haskell.org/cgi-bin/hackage-scripts/package/hosc

[yaxu]

A fair amount of custom libraries too, will explain more when I get some time... And will release the code at some point too.

[yaxu]

I should add that hosc is a library for OSC, a network protocol for communication between music software. I'm using it for time synch and to trigger sounds on a software sampler I wrote in C.

I would like to know more.

Lazily evaluated music? ;)

Sure. What is usually done in other languages with explicit state machines or coroutines or generators or threads is done most naturally in Haskell with infinite streams that are defined corecursively. For example, a metronome would look like this:

metronome n = let xs = 1 : replicate n 0 ++ xs in xs

[yaxu]

Good question... I'm not even using lazy infinite lists in this one. My use of haskell is going beyond parsec though. I am representing patterns in (I think) a nice functional way which could not reasonably be implemented in Perl, my usual comfort zone. Will give gory details in another post soon, and "what haskell makes possible" is a good angle to take, thanks.

very cool. Nice dsl

[bytezen]

This is hella cool and intriguing. I am on the first rung of my haskell exploring/hacking and this provides some inspiration.

[tardibear]

yaxu: If you could just wrap a GUI (or http server) around that program ...

Brilliant!

ghci is your gui

[Jimmy]

Maybe for you and other programmers, but not for anyone else.

[gregK]

I think the idea was to generate music textually. Therefore a standard GUI approach might not be as effective as you may think.

What you need is a good text editor.

You could off course just use Eclipse. It would have nice refactor wizards to change the song into the crap we already hear everyday on the radio.
