| − | == Version 5 ==
| + | |
| − | | + | |
| − | In Version 5 we want to improve some of the Xtend language concepts and features.
| + | |
| − | Codename is Xtend++ :
| + | |
| − | | + | |
| − | === Imports ===
| + | |
| − | The import mechanism should be overworked, so that every import is explicite.
| + | |
| − | We won't need any metamodel configuration in the workflow nor in the editors anymore.
| + | |
| − | This will not only make the setup simpler but will also improve the performance.
| + | |
| − | | + | |
| − | The syntax would change to something like the following:
| + | |
| − | | + | |
| − | import org:openarchitectureware:Extension; // native import
| + | |
| − | import EMF "my/package/model.ecore"; // non-native import
| + | |
| − | import UML "my/test.profile.uml" as profile; // non-native import with name space definition
| + | |
| − | | + | |
| − | ==== Native import ====
| + | |
| − | A native import refers to another extension file imports all public members (types, functions, extensions).
| + | |
| − | | + | |
| − | ==== Non-native Import ====
| + | |
| − | A non native import starts with an identifier pointing to an installed adapter.
| + | |
| − | The adapter is responsible for loading and converting the members from the given string.
| + | |
| − | The syntax in the string is defined by the adapter.
| + | |
| − | | + | |
| − | ==== Namespace definition ====
| + | |
| − | All members are included without namespace information. If you need a namespace you can explicitely define one per import.
| + | |
| − | | + | |
| − | ==== Reexport ====
| + | |
| − | The reexport keyword will be supported.
| + | |
| − | | + | |
| − | === Object construction pattern ===
| + | |
| − | We are thinking about a syntax to create model graphs inline.
| + | |
| − | We need this not only for model transformations but also for writing model transformation tests.
| + | |
| − | | + | |
| − | Example:
| + | |
| − | | + | |
| − | new Entity as e {
| + | |
| − | name := "Person";
| + | |
| − | references += new Reference {
| + | |
| − | name := "partner"
| + | |
| − | type := e
| + | |
| − | }
| + | |
| − | }
| + | |
| − | | + | |
| − | ==== Assignments ====
| + | |
| − | They are just another syntax for invoking a setter resp. adder-operation (which will be removed).
