Data.List.InnToOut.Basic

Various additional operations on lists

Operations to apply a function or two different functions to an element of the outer list (some of them create inner list)

mapI :: (a -> Bool) -> (a -> [a]) -> [a] -> [a]

Function that applies additional function f :: a -> [a] to a if p :: a -> Bool and p a = True

mapI2 :: (a -> Bool) -> (a -> b) -> (a -> [b]) -> [a] -> [b]

Function that applies additional function f :: a -> b to a if p :: a -> Bool and p a = True and otherwise another function g :: a -> [b] to [a] and combines results to obtain [b]
