Exact lookup

1. lookupAttr :: QName -> [Attr] -> Maybe String

   xml	Text.XML.Light.Proc

   Lookup attribute name from list.

2. lookupAttrBy :: (QName -> Bool) -> [Attr] -> Maybe String

   xml	Text.XML.Light.Proc

   Lookup the first attribute whose name satisfies the given predicate.

3. lookupCurveNameByOID :: OID -> Maybe CurveName

   crypton-x509	Data.X509.EC

   Return the curve name associated to an OID

4. 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-lib	Diagrams.Names

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

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

   diagrams-lib	Diagrams.Names

   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.

6. lookupOf :: Eq k => Getting (Endo (Maybe v)) s (k, v) -> k -> s -> Maybe v

   diagrams-lib	Diagrams.Prelude

   The lookupOf function takes a Fold (or Getter, Traversal, Lens, Iso, etc.), a key, and a structure containing key/value pairs. It returns the first value corresponding to the given key. This function generalizes lookup to work on an arbitrary Fold instead of lists.

   >>> lookupOf folded 4 [(2, 'a'), (4, 'b'), (4, 'c')]
   Just 'b'
   

   >>> lookupOf each 2 [(2, 'a'), (4, 'b'), (4, 'c')]
   Just 'a'
   

   lookupOf :: Eq k => Fold s (k,v) -> k -> s -> Maybe v
   

7. lookupFlagAssignment :: FlagName -> FlagAssignment -> Maybe Bool

   Cabal-syntax	Distribution.Types.Flag

   Lookup the value for a flag Returns Nothing if the flag isn't contained in the FlagAssignment.

8. lookupComponent :: PackageDescription -> ComponentName -> Maybe Component

   Cabal-syntax	Distribution.Types.PackageDescription

   No documentation available.

9. lookup1 :: Eq k => k -> AssocList k [e] -> [e]

   hxt	Data.AssocList

   lookup with empty list (empty string) as default value

10. lookupDef :: Eq k => v -> k -> AssocList k v -> v

    hxt	Data.AssocList

    lookup with default value
