Now we create a first model and generate code.
The screenshots on this page were made with Eclipse Indigo so they might look a little different from what you see in Eclipse Juno.
Open the PyDev perspective, then click File in main menu and select new -> Pydev Project.
You can find and create perspectives under menu Window -> Open Perspective
You can also right-click the white space in the Package Explorer and choose New -> Pydev Project.
Enter the desired projectname name, possibly the desired egg name, and click Finish
When asked, you may have to choose a Python version to be used. Both Python 2.6 and 2.7 will work. The dependency on 2.6 no longer exists. You might have to tell Eclipse to auto-configure a Python interpreter, if you have not done so before.
Open the Papyrus perspective and navigate to the created project.
Create a new model by right clicking the project in the navigator and selecting New -> Other... -> AGX -> AGX Model.
Give the model a Name: model.di (the default) will do.
Choose from the templates. At the time of this writing there are templates for
For this Hello World, we will use the Python Egg template.
Finally click finish. Some files are created. A diagram file (model.di), a UML file (model.uml), a notation file (model.notation) and an agx file (model.uml.agx).
Now you are ready to start the generator for the first time: Right-click the model.uml and select AGX -> generate.
In the Console you will see the generators output messages:
The package explorer will show the newly generated code:
Here you see a nested structure like in a namespace package. Naming the package in the model in a way as in python namespaces will yield code in that kind of nested structure.
Python eggs usually come with a file setup.py that holds setup instructions and dependencies as well as metadata like author name and email. Those can be included in the model (and thus the generated code) by adding them in so called tagged values.
Open the model file (.di) using Eclipses Papyrus perspective. In the Properties view select the Profile tab. In Applied stereotypes expand the pyegg section.
Now the available tagged values appear for the defined stereotype. Select the tagged value name you want to define a value for and click the + button on the right to add a value.
UML2 does not support multi valued tagged values. In case where enumerations are needed, value is separated by comma. Refer to Users Documentation for details.
Save changes after defining tagged values. You also have to re-run the generator for your changes to be reflected in the code.
Congratulations. You have completed your first AGX MDSD project.
