withFoldable :: Foldable t => t a -> (a -> b) -> [b] Source

Generic map function, useful for creating Views from the elements of some Foldable. Particularly handy for Maybe, as shown in the example below.

view model =
    div_ [] $
     withFoldable (model ^. mSomeMaybeVal) $ someVal ->
        p_ [] [ text $ "Hey, look at this value: " <> ms (show someVal) ]

conditionalViews :: Bool -> [View action] -> [View action] Source

Hides the Views the condition is False. Shows them when the condition is True.
