  1. mapOutput :: forall p o i u (m :: Type -> Type) a . (p -> o) -> Pipe i p u m a -> Pipe i o u m a

    conduino Data.Conduino.Internal

    Map over the downstream output type. If you want to map over the result type, use fmap.

  2. mapUpRes :: forall u v i o (m :: Type -> Type) a . (u -> v) -> Pipe i o v m a -> Pipe i o u m a

    conduino Data.Conduino.Internal

    (Contravariantly) map over the upstream result type.

  3. mappend :: Monoid a => a -> a -> a

    configuration-tools Configuration.Utils.CommandLine

    An associative operation NOTE: This method is redundant and has the default implementation mappend = (<>) since base-4.11.0.0. Should it be implemented manually, since mappend is a synonym for (<>), it is expected that the two functions are defined the same way. In a future GHC release mappend will be removed from Monoid.

  4. mapMaybeSerialized :: forall s t (m :: Type -> Type -> Type) (n :: Type -> Type) a . (Monoid s, Monoid t, InputParsing (m s), InputParsing (m t), s ~ ParserInput (m s), t ~ ParserInput (m t), InputMappableParsing m, Functor n) => (s -> Maybe t) -> (t -> Maybe s) -> Format (m s) n s a -> Format (m t) n t a

    construct Construct

    Converts a format for serialized streams of type s so it works for streams of type t instead. The argument functions may return Nothing to indicate they have insuficient input to perform the conversion.

  5. mapMaybeValue :: forall (m :: Type -> Type) a b (n :: Type -> Type) s . (Monad m, Parsing m, Show a, Show b, AlternativeFail n) => (a -> Maybe b) -> (b -> Maybe a) -> Format m n s a -> Format m n s b

    construct Construct

    Converts a format for in-memory values of type a so it works for values of type b instead. The argument functions may signal conversion failure by returning Nothing.

  6. mapSerialized :: forall s t (m :: Type -> Type -> Type) (n :: Type -> Type) a . (Monoid s, Monoid t, InputParsing (m s), InputParsing (m t), s ~ ParserInput (m s), t ~ ParserInput (m t), InputMappableParsing m, Functor n) => (s -> t) -> (t -> s) -> Format (m s) n s a -> Format (m t) n t a

    construct Construct

    Converts a format for serialized streams of type s so it works for streams of type t instead

    >>> testParse (mapSerialized ByteString.unpack ByteString.pack byte) [1,2,3]
    Right [(1,[2,3])]
    

  7. mapValue :: forall (m :: Type -> Type) a b (n :: Type -> Type) s . Functor m => (a -> b) -> (b -> a) -> Format m n s a -> Format m n s b

    construct Construct

    Converts a format for in-memory values of type a so it works for values of type b instead.

    >>> testParse (mapValue (read @Int) show $ takeCharsWhile1 isDigit) "012 34"
    Right [(12," 34")]
    
    >>> testSerialize (mapValue read show $ takeCharsWhile1 isDigit) 12
    Right "12"
    

  8. mapMaybeParserInput :: (InputMappableParsing m, InputParsing (m s), s ~ ParserInput (m s), Monoid s, Monoid s') => (s -> Maybe s') -> (s' -> Maybe s) -> m s a -> m s' a

    construct Construct.Classes

    Converts a parser accepting one input stream type to another just like mapParserInput, except the argument functions can return Nothing to indicate they need more input.

  9. mapParserInput :: (InputMappableParsing m, InputParsing (m s), s ~ ParserInput (m s), Monoid s, Monoid s') => (s -> s') -> (s' -> s) -> m s a -> m s' a

    construct Construct.Classes

    Converts a parser accepting one input stream type to another. The functions forth and back must be inverses of each other and they must distribute through <>:

    f (s1 <> s2) == f s1 <> f s2
    

  10. mapAndUnzipM :: Applicative m => (a -> m (b, c)) -> [a] -> m ([b], [c])

    control-monad-free Control.Monad.Free

    The mapAndUnzipM function maps its first argument over a list, returning the result as a pair of lists. This function is mainly used with complicated data structures or a state monad.
