Generate the GMF fragment with Dawn

Before you start make sure that you have the following components installes:

  • EMF
  • CDO
  • Dawn
  • GMF

We will examine the Dawn Codegen by using the Acore example from the Dawn SDK. In the beginning we need to get all necessary model files. Open the Plug-ins View (Window-->Show View-->Others) as shown in the picture below.

Now select the plug-in org.eclipse.emf.cdo.dawn.examples.acore and import it as soure plug-in

Now we will generate the code as you would do it for a normal project. This means the model code, the edit plug-in and GMF diagram plug-in.



Now your workspace contains the plug-ins: the one containing the model code, the edit plug-in and the diagram plug-in. Now right click the the gmf gen model an examine the context menu. You will see an additional entry called "Generate Dawn Genmodel"


Running this will create a new file called acore.dawngenmodel. This model contains specific information for the Dawn generator.


For example it allows to configure the names of the extension classes generated by dawn.


In a final step now right click the Dawn genmodel and choose "Generate Dawn GMF Fragment" from the context menu.


Now a fragment will be created containing all the specific extensions for your diagram.
