I wonder how I can get the manyTill to be happy with eof before finding the //? I tried

parseText = manyTill anyChar (try (string "//") <|> eof)

but got a type error.

You can use 'notFollowedBy' [...]

You get a type error because `string "//"` parses to a `String` while `eof` parses to a `()`. Instead you might use: parseText = manyTill anyChar (try (string "//" >> return ()) <|> eof) -- Jason Dusek
