mappend :: Monoid a => a -> a -> aoptparse-applicative Options.Applicative.Builder 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.
mapParser :: (forall x . () => ArgumentReachability -> Option x -> b) -> Parser a -> [b]optparse-applicative Options.Applicative.Common Map a polymorphic function over all the options of a parser, and collect the results in a list.

conduit Conduit Consume a source with a strict accumulator, in a way piecewise defined by a controlling stream. The latter will be evaluated until it terminates.
>>> let f a s = liftM (:s) $ mapC (*a) =$ CL.take a >>> reverse $ runIdentity $ yieldMany [0..3] $$ mapAccumS f [] (yieldMany [1..]) [[],[1],[4,6],[12,15,18]] :: [[Int]]

conduit Conduit mapWhileC with a break condition dependent on a strict accumulator. Equivalently, mapAccum as long as the result is Right. Instead of producing a leftover, the breaking input determines the resulting accumulator via Left.
mapAccumWhileMC :: Monad m => (a -> s -> m (Either s (s, b))) -> s -> ConduitT a b m sconduit Conduit Monadic mapAccumWhileC.
mapC :: forall (m :: Type -> Type) a b . Monad m => (a -> b) -> ConduitT a b m ()conduit Conduit Apply a transformation to all values in a stream.
-
conduit Conduit Apply a transformation to all elements in a chunked stream.
mapMC :: Monad m => (a -> m b) -> ConduitT a b m ()conduit Conduit Apply a monadic transformation to all values in a stream. If you do not need the transformed values, and instead just want the monadic side-effects of running the action, see mapM_.
mapMCE :: (Monad m, Traversable f) => (a -> m b) -> ConduitT (f a) (f b) m ()conduit Conduit Apply a monadic transformation to all elements in a chunked stream.
mapM_C :: Monad m => (a -> m ()) -> ConduitT a o m ()conduit Conduit Apply the action to all values in the stream. Note: if you want to pass the values instead of consuming them, use iterM instead.
