Single Chars
charIgnoreCase :: Monad m => Char -> Parser Char m Char Source #
Match a specific character ignoring case.
asciiLower :: Monad m => Parser Char m Char Source #
Match any character that satisfies isAsciiLower
asciiUpper :: Monad m => Parser Char m Char Source #
Match any character that satisfies isAsciiUpper
punctuation :: Monad m => Parser Char m Char Source #
Match any character that satisfies isPunctuation
Char Sequences
string :: Monad m => String -> Parser Char m String Source #
Match the input with the supplied string and return it if successful.
stringIgnoreCase :: Monad m => String -> Parser Char m String Source #
Match the input with the supplied string and return it if successful.
Digit Sequences (Numbers)
decimal :: (Monad m, Integral a) => Parser Char m a Source #
Parse and decode an unsigned integral decimal number.
hexadecimal :: (Monad m, Integral a, Bits a) => Parser Char m a Source #
Parse and decode an unsigned integral hexadecimal number. The hex digits
'a'
through 'f'
may be upper or lower case.
Note: This parser does not accept a leading "0x"
string.
