Text.Parsec.Rfc2234
Description
This module provides parsers for the grammar defined in
RFC2234, "Augmented BNF for Syntax Specifications:
ABNF", http://www.faqs.org/rfcs/rfc2234.html. The
terminal called char in the RFC is called character
here to avoid conflicts with Parsec's char function.

Parser Combinators
caseChar :: Stream s m Char => Char -> ParsecT s u m Char Source #
Case-insensitive variant of Parsec's char function.
caseString :: Stream s m Char => String -> ParsecT s u m () Source #
Case-insensitive variant of Parsec's string function.
manyNtoM :: Int -> Int -> ParsecT s u m a -> ParsecT s u m [a] Source #
Match a parser at least n times, but no more than m times.
parsec2read :: Parser a -> String -> [(a, String)] Source #
Helper function to generate Parser-based instances for
the Read class.
Primitive Parsers
character :: Stream s m Char => ParsecT s u m Char Source #
Match any 7-bit US-ASCII character except for NUL (ASCII value 0, that is).
ctl :: Stream s m Char => ParsecT s u m Char Source #
Match any US-ASCII control character. That is any character with a decimal value in the range of [0..31,127].
hexdig :: Stream s m Char => ParsecT s u m Char Source #
Match any character that is valid in a hexadecimal number; ['0'..'9'] and ['A'..'F','a'..'f'] that is.
vchar :: Stream s m Char => ParsecT s u m Char Source #
Match any printable ASCII character. (The "v" stands for "visible".) That is any character in the decimal range of [33..126].
