haskell error- parse error on input '='

Question

I am compiling this code and receving the error of "parse error on input '='`

import System.IO  
import Data.List.Split
main = do  
   handle <- openFile "ac/abc" ReadMode  
   contents <- hGetContents handle  
   let xs = splitOneOf "; \n " contents       
   print xs   
   readStrList contents = do 
       print contents
   hClose handle

please suggest what is wrong

What are you trying to accomplish with the readStrList line? — ehird

The problem is in these lines:

readStrList contents = do 
    print contents

If you're trying to define readStrList, then you need to put let in front:

let readStrList contents = do
        print contents

But that definition wouldn't do anything, since contents would shadow the outer contents, and the function is never called. (Not saying you're wrong, just that I can't make heads or tails of what the line is trying to do, but that's probably not it.)

@Chuck: I assumed that it was intended to be used later on within the do block. But I agree, it's difficult to tell what's intended here.
