GenGMF

The Eclipse DemoCamps are currently happening all over the world. Six of them will take place in Germany and Berlin is one of the cities — scheduled for the 27^th November. I am organizing the DemoCamp with support from my employer b+m and in cooperation with Tom Ritter from the Fraunhofer FOKUS institute. There are a lot of really interesting talks. My favorites are the talks about CDO by Eike Stepper and GEF3D by Jens von Pilgrim. I am going to give a talk about GenGMF (What else? …) in Berlin as well as in Leipzig and I would be happy to see you there too!

Please reserve a seat for the democamp in Berlin here or here, because the room has only enough space for 50 people.

I’ve created a mailing list for the project. If you have any question regarding the project, please subscribe to the GenGMF-help list and ask there.

CompartmentMapping’ s which where previously created for each ChildReference and each ChildNodeMapping are now created only once for each Compartment. There was also a small bug about a non-existend createNodesFromTemplate operation, which has been fixed too.

The support for LinkMapping’s based on references has been completed. This includes also a change in the metamodel. The demo-project has been updated too. It demonstrate how to use the reference edge descriptors.

There where two minor bugs (one in GenGMF and one in EMF) causing together a major problem on systems which use a backslash for paths strings (which are apparently only the variants of “Windows” …):

label reference attributes ‘[null]‘ not in class ‘null’!
containmant feature null with class null must support the class null

As this is fixed in 1.0.4 you may wish to upgrade (Thanks to Marius for providing a windows system for testing and debugging).

It is now possible to set up a “node-private compartment”. So you don’t have to create separate template trees for one specific node (where a template doesn’t make so much sense). Additionally the EMFUtil.Copier is now used for coping the template trees instead of my “re-invented wheel”.

With this version

• error messages occurring in the generation process are shown,
• the metamodel has changed a bit and therefore the demo-project has changed too,
• the demo-project shows some capabilities of a post processing filter and
• the update-site contains the AspectJ runtime libraries now.

I’ve created a small demo project to demonstrate the facilities of GenGMF.

Some instructions to follow:

• import the project
• generate the emf stuff from the src-model/demo.genmodel
• right-click on the demo.gengmf-file and select “Generate GMF-Graph and -Map models”
• right-click on the demo.gmfmap-file, select “Create generator model…” and follow the wizard
• right-click on the demo.gmfgen-file and select “Generate diagram code”
• run the newly created diagram plugin in as Eclipse Application.

Now you should be able to create a demo diagram using the new file wizard and draw simple nodes and edges.

The gmfgraph and gmfmap files where created from the gengmf model. In this example the graph and map templates are relative simple to show the basics of the templating facilities.

As of version 1.0.1 support for adding facets to DiagramElements and foreground/background constant/rgb colors to Figures has been added. The model generator stuff has moved to it’s own generator plugin.

This is to announce the version 1.0.0 of GenGMF.

Features:

• GMF-Graph and -Map generation using a templating engine
• creation filter for changing the EClass on the fly (e.g. Rectangle to RoundedRectangle)
• post processing for complex structure changes and attribute

Currently only edges with its own EClass are supported. EReference-edges may work too, but they have not been tested at all.

To install the plugins please use the update site.
