  1. lookupNode :: Ord a => a -> NodeMap a -> Maybe Node

    fgl Data.Graph.Inductive.NodeMap

    Lookup for the node in the map.

  2. lookupDefault :: StaticMap t => Val t -> Key t -> t -> Val t

    relude Relude.Extra.Map

    Return the value to which the specified key is mapped, or the default value if this map contains no mapping for the key. 

    >>> let myHashMap = HashMap.fromList [('a', "xxx"), ('b', "yyy")]

>>> lookupDefault "zzz" 'b' myHashMap
"yyy"

    >>> lookupDefault "zzz" 'c' myHashMap
"zzz"

  3. lookupEnv :: MonadIO m => String -> m (Maybe String)

    relude Relude.Lifted.Env

    Lifted version of lookupEnv.

  4. lookupSub :: forall nm b (v :: Type -> Type) n m . IsName nm => nm -> SubMap b v n m -> Maybe [Subdiagram b v n m]

    diagrams-core Diagrams.Core

    Look for the given name in a name map, returning a list of subdiagrams associated with that name. If no names match the given name exactly, return all the subdiagrams associated with names of which the given name is a suffix.

  5. lookupName :: forall nm (v :: Type -> Type) m n b . (IsName nm, Metric v, Semigroup m, OrderedField n) => nm -> QDiagram b v n m -> Maybe (Subdiagram b v n m)

    diagrams-core Diagrams.Core.Types

    Lookup the most recent diagram associated with (some qualification of) the given name.

  6. lookupSub :: forall nm b (v :: Type -> Type) n m . IsName nm => nm -> SubMap b v n m -> Maybe [Subdiagram b v n m]

    diagrams-core Diagrams.Core.Types

    Look for the given name in a name map, returning a list of subdiagrams associated with that name. If no names match the given name exactly, return all the subdiagrams associated with names of which the given name is a suffix.

  7. lookupBy1st :: Ord a => a -> BiMultiMap a b v -> Set (b, v)

    distributed-process Control.Distributed.Process.Internal.BiMultiMap

    Looks up all the triplets whose first component is the given value.

  8. lookupBy2nd :: Ord b => b -> BiMultiMap a b v -> Set (a, v)

    distributed-process Control.Distributed.Process.Internal.BiMultiMap

    Looks up all the triplets whose second component is the given value.

  9. lookupDefault :: (Eq k, Hashable k) => v -> k -> InsOrdHashMap k v -> v

    insert-ordered-containers Data.HashMap.Strict.InsOrd

    No documentation available.

  10. lookupMeta :: Text -> Meta -> Maybe MetaValue

    pandoc-types Text.Pandoc.Definition

    Retrieve the metadata value for a given key.
