Text.ParserCombinators.Parsec.Char · parsec-3.1.18.0

Note that numeric digits outside the ASCII range (such as arabic-indic digits like e.g. "٤" or U+0664), as well as numeric characters which aren't digits, are parsed by this function but not by digit.

valueletter :: Stream s m Char => ParsecT s u m Char

#

Parses an alphabetic Unicode characters (lower-case, upper-case and title-case letters, plus letters of caseless scripts and modifiers letters according to isAlpha). Returns the parsed character.

valuedigit :: Stream s m Char => ParsecT s u m Char

#

Parses an ASCII digit. Returns the parsed character.

valuehexDigit :: 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.

valueoctDigit :: Stream s m Char => ParsecT s u m Char

#

Parses an octal digit (a character between '0' and '7'). Returns the parsed character.

valuechar :: 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 ';'

valuestring :: 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"

Consider using string'.

valueanyChar :: Stream s m Char => ParsecT s u m Char

#

This parser succeeds for any character. Returns the parsed character.

valueoneOf :: 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"

valuenoneOf :: 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"

valuesatisfy :: 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.
