Exact lookup

1. lookup_ :: forall be (db :: (Type -> Type) -> Type) table . (Database be db, Table table, BeamSqlBackend be, HasQBuilder be, SqlValableTable be (PrimaryKey table), HasTableEquality be (PrimaryKey table)) => DatabaseEntity be db (TableEntity table) -> PrimaryKey table Identity -> SqlSelect be (table Identity)

   beam-core	Database.Beam.Query

   Convenience function to generate a SqlSelect that looks up a table row given a primary key.

2. lookupEntity :: Text -> Maybe Text

   commonmark	Commonmark.Entity

   Lookup an entity, using lookupNumericEntity if it starts with # and lookupNamedEntity otherwise

3. lookupReference :: Typeable a => Text -> ReferenceMap -> Maybe a

   commonmark	Commonmark.ReferenceMap

   Lookup a reference in a reference map. If there are several values at this key, we return the first one in the list that can be converted to an a.

4. lookupDefault :: Configured a => a -> Config -> Name -> IO a

   configurator	Data.Configurator

   Look up a name in the given Config. If a binding exists, and the value can be converted to the desired type, return it, otherwise return the default value.

5. lookupContext :: FromContext a b => Text -> Context a -> Maybe b

   doctemplates	Text.DocTemplates

   No documentation available.

6. lookupContext :: FromContext a b => Text -> Context a -> Maybe b

   doctemplates	Text.DocTemplates.Internal

   No documentation available.

7. lookupComparison :: String -> TypeRep -> [Expr] -> Maybe Expr

   express	Data.Express

   O(n). Lookups for a comparison function (:: a -> a -> Bool) with the given name and argument type.

8. lookupName :: [Expr] -> Expr -> String

   express	Data.Express

   O(n+m). Like name but lifted over an instance list and an Expr.

   > lookupName preludeNameInstances (val False)
   "p"
   

   > lookupName preludeNameInstances (val (0::Int))
   "x"
   

   This function defaults to "x" when no appropriate name is found.

   > lookupName [] (val False)
   "x"
   

9. lookupNames :: [Expr] -> Expr -> [String]

   express	Data.Express

   O(n+m). A mix between lookupName and names: this returns an infinite list of names based on an instances list and an Expr.

10. lookupComparison :: String -> TypeRep -> [Expr] -> Maybe Expr

    express	Data.Express.Instances

    O(n). Lookups for a comparison function (:: a -> a -> Bool) with the given name and argument type.
