Hello,
I get input (x) from user, convert it to Int by let y = (read x)::Int and then I would like the function to behave in a special way if user gave nothing (empty string).
-- In this place I would like to handle situation in which user
-- gave empty string as argument
-- this doesnt work :/
yearFilter [] y = True
--This works fine as far as y is integer
yearFilter x y | x == (objectYear y) = True
| otherwise = False
Thanks for help, Bye
