This may be relevant or not, but I thought morse required a delimiting character between letters, because otherwise the message was ambiguous? I seem to recall somewhere that Parsec didn't handle non-deterministic parsings very well (or at all).

You could be right about delimiters, but handling the ambiguous instances is the challenge in this case, which is a Ruby Quiz [http://www.rubyquiz.com/quiz121.html] - I thought it would be a good use for Parsec, and the user guide talks about try..<|> as the tool for it, as in
testOr2 = try (string "(a)") <|> string "(b)"
After posting I realised the difference between parsing "(a)" <|> "(b)" and parsing "a" <|> "aa" ... so Parsec doesn't do the latter well or at all? -- View this message in context: http://www.nabble.com/Parsec-beginners-problem-tf3657821.html#a10220156 Sent from the Haskell - Haskell-Cafe mailing list archive at Nabble.com.
