Please, I'm trying to do some user user input validation, but it looks like my approach is not correct. Here is my code: textInput :: IO () textInput | dataIn == "bye" = return () | otherwise = textInput where dataIn <- getLine the idea is that when user inputs "bye" the program should end/return. Problem is that I'm getting 'parse error on input `<-'' error. How can I achieve it? Another question I have is: how can I have more actions in guard, when the condition is valid. Something like (write on IO + return if dataIn == "bye): textInput :: IO () textInput *| dataIn == "bye" = (puStrLn "quitting", return () ) -- * | otherwise = textInput where dataIn <- getLine Millions of thanks for any kind of input.. Cheers, Miro
