  1. satisfyMaybe :: (Word8 -> Bool) -> Scanner (Maybe Word8)

    scanner Scanner.Internal

    Consume a single octet in case it satisfies the predicate

  2. enumMaybe :: (Bounded a, Enum a, Eq str) => (a -> str) -> str -> Maybe a

    shell-utility Shell.Utility.ParseArgument

    No documentation available.

  3. fromStateMaybe :: (a -> StateT s Maybe b) -> s -> T a b

    synthesizer-core Synthesizer.Causal.Process

    No documentation available.

  4. catMaybes :: T (Maybe a) -> T a

    synthesizer-core Synthesizer.State.Signal

    No documentation available.

  5. mapMaybePickFn :: (a -> Maybe b) -> Renderable a -> Renderable b

    Chart Graphics.Rendering.Chart.Renderable

    Map a function over the result of a renderable's pickfunction, keeping only Just results.

  6. mapMaybeAnnotation :: (AnnC a, AnnC b) => (a -> b) -> Annotation -> Annotation

    annotated-exception Data.Annotation

    Map a function over the Annotation, leaving it unchanged if the types don't match.

  7. mapMaybeS :: forall (m :: Type -> Type) a b . Monad m => Automaton m a b -> Automaton m (Maybe a) (Maybe b)

    automaton Data.Automaton

    Only step the automaton if the input is Just.

  8. throwMaybe :: forall (m :: Type -> Type) e void . Monad m => Automaton (ExceptT e m) (Maybe e) (Maybe void)

    automaton Data.Automaton.Trans.Except

    When the input is Just e, throw the exception e. This does not output any data since it terminates on the first nontrivial input.

  9. throwOnMaybe :: forall (m :: Type -> Type) a e . Monad m => (a -> Maybe e) -> Automaton (ExceptT e m) a a

    automaton Data.Automaton.Trans.Except

    When the predicate evaluates to Just e, throw the exception e, otherwise forward the input.

  10. catchMaybe :: forall (m :: Type -> Type) a b . (Functor m, Monad m) => Automaton (MaybeT m) a b -> Automaton m a b -> Automaton m a b

    automaton Data.Automaton.Trans.Maybe

    When an exception occurs in the first automaton, the second automaton is executed from there.
