lookupJust :: (Eq a, Partial) => a -> [(a, b)] -> bhledger Hledger.Cli.Script lookupJust key = fromJust . lookup key

takingJusts :: forall a (m :: Type -> Type) . Monad m => MachineT m (Is (Maybe a)) amachines Data.Machine.Process A Process that passes through elements unwrapped from Just until a Nothing is found, then stops. This can be constructed from a plan with
takingJusts :: Process (Maybe a) a takingJusts = repeatedly $ await >>= maybe stop yield
Examples:>>> run $ takingJusts <~ source [Just 1, Just 2, Nothing, Just 3, Just 4] [1,2]
adjust :: (Ord k, MonoidNull v) => (v -> v) -> k -> MonoidMap k v -> MonoidMap k vmonoidmap Data.MonoidMap Adjusts the value associated with the given key. Satisfies the following property:
adjust f k m == set k (f (get k m)) m
