convert :: String -> [Int] convert = map read . words
read :: FilePath -> IO [[Int]] read fp = (map convert . lines) `fmap` readFile fp
Naming the new function read is a bad idea :)
Right now I am using hGetLine and getting a string. Is is possible to use read to convert this in a list of Num?
As Felipe demonstrates, putting the entire file into a String via readFile is often easier than reading it piecemeal with hGetLine . Regards, apfelmus
