Combinators
As the dual of oneOf, noneOf cs succeeds if the current
character is not in the supplied list of characters cs. Returns the
parsed character.
consonant = noneOf "aeiou"Skips zero or more white space characters. See also skipMany.
Parses a white space character (any character which satisfies isSpace) Returns the parsed character.
Parses a newline character ('\n'). Returns a newline character.
Parses a tab character ('\t'). Returns a tab character.
Parses an upper case letter. Returns the parsed character.
Parses a lower case character. Returns the parsed character.
Parses a letter or digit. Returns the parsed character.
Parses a letter (an upper case or lower case character). Returns the parsed character.
Parses a digit. Returns the parsed character.
Parses a hexadecimal digit (a digit or a letter between 'a' and 'f' or 'A' and 'F'). Returns the parsed character.
Parses an octal digit (a character between '0' and '7'). Returns the parsed character.
Class
Additional functionality needed to parse character streams.
Methods
satisfy :: (Char -> Bool) -> m CharParse a single character of the input, with UTF-8 decoding
char :: Char -> m CharnotChar :: Char -> m CharnotChar cparses any single character other thanc. Returns the parsed character.anyChar :: m CharThis parser succeeds for any character. Returns the parsed character.
string :: String -> m Stringstring sparses a sequence of characters given bys. Returns the parsed string (i.e.s).divOrMod = string "div" <|> string "mod"text :: Text -> m Texttext tparses a sequence of characters determined by the texttReturns the parsed text fragment (i.e.t).Using
OverloadedStrings:divOrMod = text "div" <|> text "mod"

Cabal additions
Accepts negative (starting with -) and positive (without sign) integral
numbers.
Greedily munch characters while predicate holds. Require at least one character.
