Is there a framework for synchronizing properties of POJOs? For example, I want to express (in some high-level, declarative form) that foo.text = bar.text + baz.text or foo.y = (max(bars, y)).y without having to register property change, element add and remove listeners on values and (especially) collections, which are repetitive and err...
I've just finished reading a very interesting paper entitied "Out of the Tar Pit" which presents this idea of FRP as a way of reducing complexity in applications by minimizing state and control. Are there any examples of this idea out in the wild? Is anybody making use of these ideas? Is there any work being done in this area? Edit: FRP...
i'm using Haskell with the Yampa FRP library which uses the arrows language extension. how can i do a simple putStrLn in a SF? mySF = proc x -> do y <- identity -< x*x putStrLn "Hello World!" ++ show y returnA -< y the arrow syntax complains about the expression not bein an arrow (of course), but even with arrows i get no...
I am a student currently learning about Functional Reactive paradigm using F#. It's radically new viewpoint for me. Yesterday I learned about creating a simple ping-pong game using this paradigm. The idea I grasp so far is : we think values as functions of time. On its pure form, it's stateless. However, I need to remember the position o...
There has been a lot of research into ways of creating guis in a functional language. There is libraries for push/pull frp, arrow based frp and probably other superior research too. Many people seem to agree this is the more native way yet just about everyone seems to be using imperative binding libraries such as gtk2hs and wxhaskell. Ev...
I'm trying to simulate a bouncing ball with the Yampa-Framework: Given an initial x-position, height and velocity, the ball should bounce according to gravity rules. The signal function takes a "Tip-Event" as input, the idea being "when the ball is tipped, it's speed should double". The ball bounces nicely, but every time there is a tip...
