Combinators

pass :: Applicative f => f () Source #

Shorter alias for pure ().

>>> pass :: Maybe ()
Just ()

Useful shortcut when need an empty action:

printJust :: Maybe Int -> IO ()
printJust mInt = case mInt of
    Just i -> putStrLn $ "Number: " ++ show i
    Nothing -> pass

appliedTo :: Applicative f => f a -> f (a -> b) -> f b Source #

Named version of the <**> operator, which is <*> but flipped. It is helpful for chaining applicative operations in forward applications using &.

>>> Just (+ 1) & appliedTo (Just 2)
Just 3
>>> Just (+) & appliedTo (Just 1) & appliedTo (Just 2)
Just 3
>>> Nothing & appliedTo (Just 2)
Nothing
