Re: [Haskell-cafe] how to write a function to send a string to a tuple

2010/3/8 Pradeep Wickramanayake :

Hi,

Im having problems with sending a string to a tuple.

My string contains integers and strings

The whole string stay as (“test,dfdf”,3,”dfsf”)

sortList2 :: String -> String

sortList2 (x:xs)

                | x == ',' = ""

                | otherwise = [x] ++ sortList2 xs

The above function separating each words from the string

Now I need to put them to a tuple

putList :: String -> (Int, String, String, Int, Int)

putList (x:xs)

                                                |xs /="" = sortList2 ++ putList xs

I'm not sure what you're doing with the "sorting", but you could sort of hack it using `read' as such: Prelude> read "(3, \"hello\")" :: (Int, String) (3, "hello") Of course, this will crash if the input string is not parsable. Prelude> read "(3, 'a')" :: (Int, String) *** Exception: Prelude.read: no parse -- Deniz Dogan
