Re: [Haskell-beginners] Parsec problem

2 Feb 2013


      Hi.
...
keyValue = do
                    fieldName <- many letter
                    spaces
                    char '='
                    spaces
                    fieldValue <- parseToNewLine
                    return (fieldName,fieldValue)
main = parseTest keyValue "key=\n"
I don’t understand why te code above doesn’t parse to (“key”,””)
The problem is that the \n is already consumed by spaces. The
subsequent parseToNewLine fails.

Cheers,
  Andres
