any -base +parsec
This parser succeeds for any character. Returns the parsed character.
The parser anyToken accepts any kind of token. It is for example used to implement eof. Returns the accepted token.
many p applies the parser p zero or more times. Returns a list of the returned values of p.
> identifier = do{ c <- letter
> ; cs <- many (alphaNum <|> char '_')
> ; return (c:cs)
> }
many1 p applies the parser p one or more times. Returns a list of the returned values of p.
> word = many1 letter
manyTill p end applies parser p zero or more times until parser end succeeds. Returns the list of values returned by p. This parser can be used to scan comments:
> simpleComment = do{ string "<!--"
> ; manyTill anyChar (try (string "-->"))
> }
Note the overlapping parsers anyChar and string "-->", and therefore the use of the try combinator.
skipMany p applies the parser p zero or more times, skipping its result.
> spaces = skipMany space
skipMany1 p applies the parser p one or more times, skipping its result.
