- Synopsis
- A fold function for Bool
- Description
The bool function allows folding over boolean values.
This is comparable to the maybe or either functions on their respective types.
The bool function is a replacement for the build-in
if then else-syntax. However, since it is a function, it can be partially applied and passed around to higher order functions, like so:ghci> :m + Data.Bool.Extras ghci> let yesOrNo = bool "no" "yes" ghci> map yesOrNo [True, False, True] ["yes", "no", "yes"]Note that the arguments to bool are in the opposite order of the
if then else-syntax; First the false value, then the true value, and finally the boolean.- Author
