New to Haskell - Question about hugsIORun from old Prelude
Hello, I am trying to rewrite some older (2001) haskell : myReadFile :: String -> String myReadFile f = case hugsIORun (readFile f) of Right s -> s Left _ -> "" Can someone provide me with a up to date version of the above bit of code without using code from the old Prelude? Thanks, R _________________________________________________________________ Visit MSN Holiday Challenge for your chance to win up to $50,000 in Holiday cash from MSN today! http://www.msnholidaychallenge.com/index.aspx?ocid=tagline&locale=en-us
The current necromancy would probably be:
import System.IO.Unsafe import System.IO
myReadFile :: String -> String myReadFile fname = unsafePerformIO $ readFile fname `catch` const (return "")
On which subject allow me to comment that zombies smell bad.
