type ShowS = String -> String
shows :: Show a => a -> ShowS
showChar :: Char -> ShowS
showString :: String -> ShowS
showParen :: Bool -> ShowS -> ShowS
showList__ :: (a -> ShowS) -> [a] -> ShowS
showSpace :: ShowS
showLitChar :: Char -> ShowS

Convert a character to a string using only printable characters, using Haskell source-language escape conventions. For example: 

 showLitChar '\n' s  =  "\\n" ++ s
protectEsc :: (Char -> Bool) -> ShowS -> ShowS
intToDigit :: Int -> Char
Convert an Int in the range 0..15 to the corresponding single digit Char. This function fails on other inputs, and generates lower-case hexadecimal digits.
showSignedInt :: Int -> Int -> ShowS
appPrec :: Int
appPrec1 :: Int
asciiTab :: [String]
