Re: [Haskell-cafe] Simple Parsec example

Thanks, Albert. The code is from this page, just below the definition of parse: http://hackage.haskell.org/packages/archive/parsec/latest/doc/html/Text-Pars... Michael --- On Sun, 8/7/11, Albert Y.

The problem is deeper than imports. import Text.Parsec.Prim(parse) import Text.Parsec.Token(makeTokenParser,   GenTokenParser(TokenParser, commaSep, integer)) import Text.Parsec.Language(emptyDef) main = case (parse numbers "" "11, 2, 43") of          Left err  -> print err          Right xs  -> print (sum xs) numbers = c i where   TokenParser{commaSep=c, integer=i} = makeTokenParser emptyDef _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
