Hi,
The function getMyLine written by me is intended for getting a complete
string from the standard input.
import IO
getMyLine :: IO [Char]
getMyLine = do
c <- getChar
if(c == '\n')
then return ""
else cs <- getMyLine
return [c]
However I keep getting the following error:
io.hs:14:2: Parse error in pattern
Failed, modules loaded: none.
I fail to understand what the error is. I tried out various things
such as changing the alignment and so on to no avail. The following program,
however, compiled successfully though it has the same structure as the
previous program.
checkd :: IO Bool
checkd = do
c <- getChar
if(c=='d')
then return True
else return False
Prelude> :load ./io.hs
[1 of 1] Compiling Main ( io.hs, interpreted )
Ok, modules loaded: Main.
*Main> checkd
d
True
