mapLogMessage :: MonadLog message' m => (message -> message') -> LoggingT message m a -> m alogging-effect Control.Monad.Log Re-interpret the log messages in one computation. This can be useful to embed a computation with one log type in a larger general computation.
mapLogMessageM :: MonadLog message' m => (message -> m message') -> LoggingT message m a -> m alogging-effect Control.Monad.Log Monadic version of mapLogMessage. This can be used to annotate a message with something that can only be computed in a monad. See e.g. timestamp.

logging-effect Control.Monad.Log LoggingT unfortunately does admit an instance of the MFunctor type class, which provides the hoist method to change the monad underneath a monad transformer. However, it is possible to do this with LoggingT provided that you have a way to re-interpret a log handler in the original monad.

Types which represent functions k -> v A typeclass and a number of implementations; please read README.md on github
mapKeysAntitonic :: (k -> l) -> Piecewise k v -> Piecewise l vmappings Data.Mapping.Piecewise Alter keys according to a function, assumed to be antitone (not checked)
mapKeysMonotonic :: (k -> l) -> Piecewise k v -> Piecewise l vmappings Data.Mapping.Piecewise Alter keys according to a function, assumed to be monotone (not checked)
mapLinear :: (Double -> b) -> Double -> Double -> Double -> [b]matplotlib Graphics.Matplotlib A handy miscellaneous function to linearly map over a range of numbers in a given number of steps
