module Data.Dates.Parsing.Internal

-- | Parsers the parser at least once, but no more than n times.
takeN1 :: Stream s m Char => Int -> ParsecT s st m a -> ParsecT s st m [a]

-- | Parse natural number of N digits which is not greater than M
number :: (Stream s m Char, Read a, Num a, Ord a) => Int -> a -> ParsecT s st m a
pYear :: Stream s m Char => ParsecT s st m Int
pYearNormal :: Stream s m Char => ParsecT s st m Int
readNum :: (Num a, Stream s m Char) => ParsecT s st m a
yearAbbreviations :: Stream s m Char => ParsecT s st m String
makeAbbr :: String -> [String]
pYearAny :: Stream s m Char => ParsecT s st m Int
monthAssoc :: [(String, Month)]
casings :: String -> [String]

-- | Parse various capitalizations of the given string, but always return
--   the same string on success.
parseAs :: Stream s m Char => [String] -> String -> ParsecT s st m String
pMonthName :: Stream s m Char => ParsecT s st m Month
pMonth :: Stream s m Char => ParsecT s st m Month
pDay :: Stream s m Char => ParsecT s st m Int
uppercase :: String -> String

-- | Case-insensitive version of <a>isPrefixOf</a>
isPrefixOfI :: String -> String -> Bool

-- | Use a data type's Bounded, Enum and Show instances to determine if the
--   given string uniquely matches a constructor. The comparison is
--   case-insensitive and starts from the beginning of the strings (so a
--   partial constructor name can still match if there are enough
--   characters for a unique match)
--   
--   For example:
--   
--   <pre>
--   data Things = Foo | Bar | Baz deriving (Bounded, Enum, Show)
--   
--   -- Right Foo
--   uniqFuzzyMatch "f" :: Either [Things] Things
--   
--   -- Left [Bar, Baz]
--   uniqFuzzyMatch "ba" :: Either [Things] Things
--   </pre>
uniqFuzzyMatch :: (Bounded a, Enum a, Show a) => String -> Either [a] a
