Hi to all,
i am a newbie in Haskell, and it has recently become my nightmare.. i have several years of programming experince, but i have never been stuck like this..
please share your knowlodge, if you have any about my problem.. so here is my basic and first problem;
i have a text file and lines in it, i need to get the contents of the file line by line to a list in my program..

Then i will process the list in some way this is not the deal.. the big deal is how do i get the contents of the file line by line to a list !?
i will appreciate any help.. Thanks..

i have a text file and lines in it, i need to get the contents of the file line by line to a list in my program..

Code

main = do
  c <- getContents
  let ls0 = lines c
  let ls1 = map process_line ls0
  putStr (unlines ls1)


process_line xs = drop 3 xs

Now:

$ cat txt
1232652

$ cat txt | runhugs test.hs
