type CharParser st = GenParser Char st Source #
spaces :: Stream s m Char => ParsecT s u m () Source #
Skips
zero
or more white space characters. See also
skipMany
.
space :: Stream s m Char => ParsecT s u m Char Source #
Parses a white space character (any character which satisfies
isSpace
)
Returns the parsed character.
newline :: Stream s m Char => ParsecT s u m Char Source #
Parses a newline character ('\n'). Returns a newline character.
tab :: Stream s m Char => ParsecT s u m Char Source #
Parses a tab character ('\t'). Returns a tab character.
upper :: Stream s m Char => ParsecT s u m Char Source #
Parses an upper case letter (according to
isUpper
).
Returns the parsed character.
lower :: Stream s m Char => ParsecT s u m Char Source #
Parses a lower case character (according to
isLower
).
Returns the parsed character.
alphaNum :: Stream s m Char => ParsecT s u m Char Source #
Parses a alphabetic or numeric Unicode characters
according to
isAlphaNum
. Returns the parsed character.
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
.
letter :: Stream s m Char => ParsecT s u m Char Source #
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.
digit :: Stream s m Char => ParsecT s u m Char Source #
Parses an ASCII digit. Returns the parsed character.
hexDigit :: Stream s m Char => ParsecT s u m Char Source #
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 Source #
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 Source #
char c
parses a single character
c
. Returns the parsed
character (i.e.
c
).
semiColon = char ';'
string :: Stream s m Char => String -> ParsecT s u m String Source #
string s
parses a sequence of characters given by
s
. Returns
the parsed string (i.e.
s
).
divOrMod = string "div"
<|> string "mod"
anyChar :: Stream s m Char => ParsecT s u m Char Source #
This parser succeeds for any character. Returns the parsed character.
oneOf :: Stream s m Char => [ Char ] -> ParsecT s u m Char Source #
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"
