Simple parsers
crlf :: forall e s m. (MonadParsec e s m, Token s ~ Word8) => m (Tokens s) Source #
Parse a carriage return character followed by a newline character. Return the sequence of characters parsed.
Categories of characters
controlChar :: (MonadParsec e s m, Token s ~ Word8) => m (Token s) Source #
Parse a control character.
spaceChar :: (MonadParsec e s m, Token s ~ Word8) => m (Token s) Source #
Parse a space character, and the control characters: tab, newline, carriage return, form feed, and vertical tab.
upperChar :: (MonadParsec e s m, Token s ~ Word8) => m (Token s) Source #
Parse an upper-case character.
lowerChar :: (MonadParsec e s m, Token s ~ Word8) => m (Token s) Source #
Parse a lower-case alphabetic character.
letterChar :: (MonadParsec e s m, Token s ~ Word8) => m (Token s) Source #
Parse an alphabetic character: lower-case or upper-case.
alphaNumChar :: (MonadParsec e s m, Token s ~ Word8) => m (Token s) Source #
Parse an alphabetic or digit characters.
printChar :: (MonadParsec e s m, Token s ~ Word8) => m (Token s) Source #
Parse a printable character: letter, number, mark, punctuation, symbol or space.
digitChar :: (MonadParsec e s m, Token s ~ Word8) => m (Token s) Source #
Parse an ASCII digit, i.e between “0” and “9”.
binDigitChar :: (MonadParsec e s m, Token s ~ Word8) => m (Token s) Source #
Parse a binary digit, i.e. “0” or “1”.
Since: 7.0.0
octDigitChar :: (MonadParsec e s m, Token s ~ Word8) => m (Token s) Source #
Parse an octal digit, i.e. between “0” and “7”.
hexDigitChar :: (MonadParsec e s m, Token s ~ Word8) => m (Token s) Source #
Parse a hexadecimal digit, i.e. between “0” and “9”, or “a” and “f”, or “A” and “F”.
asciiChar :: (MonadParsec e s m, Token s ~ Word8) => m (Token s) Source #
Parse a character from the first 128 characters of the Unicode character set, corresponding to the ASCII character set.
Single byte
char :: (MonadParsec e s m, Token s ~ Word8) => Token s -> m (Token s) Source #
A type-constrained version of single
.
newline = char 10
char' :: (MonadParsec e s m, Token s ~ Word8) => Token s -> m (Token s) Source #
The same as char
but case-insensitive. This parser returns the
actually parsed character preserving its case.
>>>
parseTest (char' 101) "E"

parseTest (char' 101) "G"
1:1: unexpected 'G' expecting 'E' or 'e'
