I am getting the following error when trying to do a show on a Ranges object :-
C:\Languages\Haskell>ghci rangeTest.hs
Loading package ghc-prim ... linking ... done.
Loading package integer-gmp ... linking ... done.
Loading package base ... linking ... done.
Loading package ffi-1.0 ... linking ... done.
[1 of 1] Compiling Main ( rangeTest.hs, interpreted )
Ok, modules loaded: Main.
*Main> main
Loading package array-0.3.0.1 ... linking ... done.
Loading package containers-0.3.0.0 ... linking ... done.
Loading package ranges-0.2.3 ... linking ... done.
Ranges [(37*** Exception: <stdout>: hPutChar: invalid argument (character is not
in the code page)
*Main>
I have attached the test source also :-
import Data.Ranges
test = (ranges [
range 32 33,
range 34 35,
range 37 39
])
main :: IO ()
main = do {
putStrLn (show test)
}
I am probably doing something fundermentaly wrong.
Many thanks in advance,
Aaron
