  1. isAlphaNum8 :: Word8 -> Bool

    text-latin1 Text.Latin1

    Test if a byte is the encoding of either a Latin-1 letter or a decimal digit.

  2. parseEnum :: forall t e a . (Bounded a, Enum a, Render a, Textual t) => Bool -> Bool -> e -> e -> t -> Either e a

    ttc Data.TTC

    Parse a value in an enumeration The Render instance determines the textual values to parse from. This function is intended to be used with types that have few choices, as the implementation uses a linear algorithm. See the enum example program in the ttc-examples directory of the source repository.

  3. parseEnum' :: forall t e a . (Bounded a, Enum a, Render a, Textual t, Textual e) => String -> Bool -> Bool -> t -> Either e a

    ttc Data.TTC

    Parse a value in an enumeration using default error messages The Render instance determines the textual values to parse from. The following English error messages are returned:

    • "invalid {name}" when there are no matches
    • "ambiguous {name}" when there is more than one match
    This function is intended to be used with types that have few choices, as the implementation uses a linear algorithm.

  4. readsEnum :: (Bounded a, Enum a, Render a) => Bool -> Bool -> ReadS a

    ttc Data.TTC

    Implement ReadS using parseEnum This implementation expects all of the input to be consumed.
