Hey all,

Trying to match C-style comments, I have:

between (string "/*") (string "*/") $ many anyChar

Which doesn't work, because it is equivalent (ignoring returned values) to

do {string "/*"; many anyChar; string "*/"}

Use "manyTill".

If the termination criterion was a single character, then I could use noneOf or (satisfy . not), but that doesn't help here.

So... what am I missing?

manyTill A quick example: Prelude Text.Parsec> parse (do {spaces; string "/*"; com <- manyTill anyChar (string "*/"); rmd <- getInput; return (com, rmd);}) "" "/* a comment */ and code /* and another comment */" Right (" a comment "," and code /* and another comment */")

Thanks in advance.
