Hi , I am a new bie to haskell. I need to read a file and get it contents line by line and then eventually word by word. I have written the code to read a file , but the returned value is all the lines in the file. How do I parse this whole text message ( contents of the file) into individual lines ( that is parsing / splitting the whole text to get me one line at a time. Also once I get the individual line, I o parse it word by word. I have a start on this thing. by using the line function in haskell, but I have not managed to write it successfully. Can anyone help me in this. Below is the code to read a file. fileFun :: IO () fileFun = do putStr "Please input a file name: " fname <- getLine contents <- readFile fname How do I split the data returned in contents( Contents contains all the text in the file, which is given as input) Thanks Anagha
Take a look at the functions lines and words. On 16 Oct 2003, Anagha wrote:
