@hackage reactive0.2

Reactive [1] is a simple foundation for programming reactive systems functionally. Like Fran/FRP, it has a notions of (reactive) behaviors and events. Like DataDriven [2], Reactive has a data-driven implementation. The main difference between Reactive and DataDriven is that Reactive builds on MVar-based "futures", while DataDriven builds on continuation-based computations.

The inspiration for Reactive was Mike Sperber's Lula [3] implementation of FRP. Mike used blocking threads, which I had never considered for FRP. While playing with the idea, I realized that I could give a very elegant and efficient solution to caching, which DataDriven doesn't do. (For an application "f <*> a" of a varying function to a varying argument, caching remembers the latest function to apply to a new argument and the last argument to which to apply a new function.)

Please share any comments & suggestions on the discussion (talk) page there.

You can configure, build, and install all in the usual way with Cabal commands.
