Documentation

empty :: MD i o Source

Match the empty string.

many :: MD i o -> MD i [o] Source

Match zero or more occurences of the given parser.

many1 :: MD i o -> MD i [o] Source

Match one or more occurences of the given parser.

notFollowedBy :: MD i o -> MD i o Source

Match if the given parser does not match.

sepBy1 :: MD i o -> MD i o' -> MD i [o] Source

Match one or more occurences of the given parser separated by the sepator.

count :: Int -> MD i o -> MD i [o] Source

Match the given parser n times.

between :: MD i t -> MD t close -> MD t o -> MD i o Source

Match the first, middle and last argument, returning the value from the middle one.

optional :: MD i o -> MD i (Maybe o) Source

Match optionally.

(>>!) :: Arrow a => a b c -> a b c' -> a b c Source
