  1. mapThese :: (a -> c) -> (b -> d) -> These a b -> These c d

    these-skinny Data.These

    Bifunctor map.

  2. mapThis :: (a -> c) -> These a b -> These c b

    these-skinny Data.These

    mapThis = over here
    

  3. mapAccum :: MonadIO m => acc -> Event (acc -> (x, acc)) -> m (Event x, Behavior acc)

    threepenny-gui Graphics.UI.Threepenny.Core

    Efficient combination of accumE and accumB.

  4. mapAccum :: MonadIO m => acc -> Event (acc -> (x, acc)) -> m (Event x, Behavior acc)

    threepenny-gui Reactive.Threepenny

    Efficient combination of accumE and accumB.

  5. mapCycle :: (Time -> Time) -> Arc -> Arc

    tidal Sound.Tidal.Boot

    Similar to fmap but time is relative to the cycle (i.e. the sam of the start of the arc)

  6. mapTableErrors :: Key -> [TomlDecodeError] -> [TomlDecodeError]

    tomland Toml.Codec.Combinator.Table

    Prepends given key to all errors that contain key. This function is used to give better error messages. So when error happens we know all pieces of table key, not only the last one.

  7. mapTup3 :: (a -> b) -> (a, a, a) -> (b, b, b)

    tools-yj Data.Tuple.ToolsYj

    No documentation available.

  8. mapTup3M :: Applicative m => (a -> m b) -> (a, a, a) -> m (b, b, b)

    tools-yj Data.Tuple.ToolsYj

    No documentation available.

  9. mapTup3M_ :: Applicative m => (a -> m b) -> (a, a, a) -> m ()

    tools-yj Data.Tuple.ToolsYj

    No documentation available.

  10. mapWithKey :: ([c] -> a -> b) -> TMap c a -> TMap c b

    trie-simple Data.Trie.Map

    Same semantics to following defintion, but have more efficient implementation.

    mapWithKey f = fromAscList .
    map (\(cs,a) -> (cs,  f cs a)) .
    toAscList
