I'm trying to use Yampa for some basic system simulation like I'd do in Simulink. In this case I want to simulate a spring and damper system, introduced by this simulink tutorial. I've written the ...

What I mean by first-order constraint First, I'll explain what I mean by first-order constraint on arrows: Due to the way arrows desugar, you cannot use a locally bound name where an arrow command...

I am learning Haskell and Yampa at the moment and have a question about the reactimate function. reactimate :: IO a -- init -> (Bool -> IO (DTime, Maybe a)) -- sense -> (Bool -> b -&...
