I'm just trying to get started with FRP and threepenny-gui, and I'm not sure how to do even basic things.
Suppose I have a function defined as so
timesClicked :: Element -> Behavior Int
timesClicked elem = accumulate (+) 0 (1 <$ UI.click elem)
and I want to display the value of the Behavoir on the page.
I can do something like
setup :: Window -> UI ()
setup rootWindow = void $ do
button <- UI.button #+ [ string "Clickity!" ]
output <- UI.p
getBody rootWindow #+
map element [ button, output ]
let clicks = timesClicked loginButton
Edit: Working full code here.
I don't know how to attach the behavior into the output.
Aha, I've got it figured out now, and am leaving this as an example for anyone else.
If anyone wants to follow along with my progress, I've put it on github.
