Hi,

Is there a way to get source position[1] information from parsec while defining a parser? It surely knows about source positions, as they are used while reporting a parsing error.

data Identifier = Identifier String SourcePos

pIdentifier :: Parser Identifier pIdentifier = do pos <- ??

pos <- getPosition

s <- pString return (Identifier s pos)

Thanks in advance,
