oneOf :: Stream s m Char => [Char] -> ParsecT s u m Char

oneOf cs succeeds if the current character is in the supplied list of characters cs. Returns the parsed character. See also satisfy. 

   vowel  = oneOf "aeiou"
noneOf :: Stream s m Char => [Char] -> ParsecT s u m Char

As the dual of oneOf, noneOf cs succeeds if the current character not in the supplied list of characters cs. Returns the parsed character. 

  consonant = noneOf "aeiou"
spaces :: Stream s m Char => ParsecT s u m ()
Skips zero or more white space characters. See also skipMany.
space :: Stream s m Char => ParsecT s u m Char
Parses a white space character (any character which satisfies isSpace) Returns the parsed character.
newline :: Stream s m Char => ParsecT s u m Char
Parses a newline character ('\n'). Returns a newline character.
tab :: Stream s m Char => ParsecT s u m Char
Parses a tab character ('\t'). Returns a tab character.
upper :: Stream s m Char => ParsecT s u m Char
Parses an upper case letter (a character between 'A' and 'Z'). Returns the parsed character.
lower :: Stream s m Char => ParsecT s u m Char
Parses a lower case character (a character between 'a' and 'z'). Returns the parsed character.
alphaNum :: Stream s m Char => ParsecT s u m Char
Parses a letter or digit (a character between '0' and '9'). Returns the parsed character.
letter :: Stream s m Char => ParsecT s u m Char
Parses a letter (an upper case or lower case character). Returns the parsed character.
digit :: Stream s m Char => ParsecT s u m Char
Parses a digit. Returns the parsed character.
hexDigit :: Stream s m Char => ParsecT s u m Char
Parses a hexadecimal digit (a digit or a letter between 'a' and 'f' or 'A' and 'F'). Returns the parsed character.
octDigit :: Stream s m Char => ParsecT s u m Char
Parses an octal digit (a character between '0' and '7'). Returns the parsed character.
char :: Stream s m Char => Char -> ParsecT s u m Char

char c parses a single character c. Returns the parsed character (i.e. c). 

  semiColon  = char ';'
anyChar :: Stream s m Char => ParsecT s u m Char
This parser succeeds for any character. Returns the parsed character.
satisfy :: Stream s m Char => (Char -> Bool) -> ParsecT s u m Char
The parser satisfy f succeeds for any character for which the supplied function f returns True. Returns the character that is actually parsed.
string :: Stream s m Char => String -> ParsecT s u m String

string s parses a sequence of characters given by s. Returns the parsed string (i.e. s). 

  divOrMod    =   string "div" 
              <|> string "mod"
