Re: [Haskell-beginners] Parsec, comma sperated list with special last element

18 Dec 2012

      I tried

file = do
  res <- endBy (try cell) (char ',')
  l   <- lastCell
  eof
  return res

cell = many1 (noneOf ",")
lastCell = many1 (noneOf "\n")

But that does not work because cell succeeds on the last cell.
I can replace the endBy by

many (try $ do {a <- cell; string ","; return a})

Still ... I can not do it with "endBy", can I?
I think you can. What have you tried with endBy that didn't work?
