automatic recompilation/re-execution?
by Shahbaz 11 Nov '08

11 Nov '08

In the mailing list announcement, one of the potential uses of this library is "automatic recompilation/re-execution." This sounds very interesting, is there more information? Is this at all similar to "Living it up with a Live Programming Language" [http://lambda-the-ultimate.org/node/2149] ? Also, are there any tutorials that show how this library can be used (rather than just explaining semantics)? Thanks

In other words, I don't think you can specify the > meaning of 'changes' in terms of the meaning of Reactive. I see what you mean: my implementation of changes only removes one kind of redundancy (reactive's simultaneous occurrences). It doesn't remove the redundancy where some occurrences may not change the value. My next thought is, why not add an Eq parameter to the changes function and use that to remove the other redundancy? I'm thinking that could work in many cases, but in this case: data WiperMode = Normal { singleWipe :: Event () , customWipe :: Event () } | SlowWipe | ContinuousWipe | FastWipe type WiperStick = Reactive WiperMode That would require me to have an Eq on WiperMode with the embedded events. I can't see a way to make that work. I think I'll just change my example to be WiperStick = Event WiperMode with a condition that there exists an occurance at -infinity. Hrm, I'm thinking this conversation should probably be on the reactive list. I'll cc it.

Can't find reactive-0.8.3

Hi, Thanks for the great work. reactive-glut.cabal has a dependency "reactive >= 0.8.3" is this correct? I've not yet understood the difference between code.haskell.org and darcs.haskell.org. Your link on the old-reactive wiki page has the wrong url with? /package/ in the path. I wish this could be standardised :) Cheers Jim
