getStateDefault :: Typeable t => Taffy IO t -> Taffy IO t Source #
Like "putState", but avoids aquiring a lock if the value is already in the map.
putState :: forall t. Typeable t => Taffy IO t -> Taffy IO t Source #
Get a value of the type returned by the provided action from the the current taffybar state, unless the state does not exist, in which case the action will be called to populate the state map.
