Hi Adrian,
How can I add a function that sorts this list that I read from the user and accumulate using the function that you described? I am not asking for a sort algorithm of course, I am just wondering how to feed the IO Path as an input to a sort function? Is it suppose to look like this:
sort :: IO Path -> IO Path
or
sort :: IO Path -> Path
How do you iterate over IO Path?
Thanks for taking time.
I don't know what iterating over something means (the opposite of iterating under something I suppose) I think you want something like this.. import List (sort) sortGet :: IO Path -> IO Path sortGet get = do got <- get return (sort got) or maybe even.. import Monad (liftM) sortGet :: IO Path -> IO Path sortGet = liftM sort Regards -- Adrian Hey
