Hi,

i would like to implement the possibility of tracing in acceleo (model to text transformation). For example for displaying the trace from the attributes of the model classes to the java code and other things. I read that there exists some traceability plug ins but i really don´t know where to start. So my question is how to start correctly and what i need to integrate.
Thank you for your help.

Hi,

You can look at the contents of the org.eclipse.acceleo.traceability plugin for the traceability-enabled implementation of the Acceleo generation engine. Traceability will be enabled if you set org.eclipse.acceleo.common.preference.AcceleoPreferences.switchTraceability(boolean) to true before starting your generation. This is only available through programmatic launches as we've removed the preference page to activate it. Take note that the traceability plugin is no longer supported and that traceability information it returns might not be 100% accurate. You can retrieve the traceability model after your generation if you've added a generation listener to the engine (org.eclipse.acceleo.engine.generation.AcceleoEngine.addListener(IAcceleoTextGenerationListener)) that notifies the engine it is interested in "generation end" events (org.eclipse.acceleo.engine.event.IAcceleoTextGenerationListener.listensToGenerationEnd() returns true). In such a case, the AcceleoTextGenerationEvent sent to the listener's "generationEnd" method will contain the evaluation traces in the form of a org.eclipse.acceleo.traceability.TraceabilityModel object.

Thank you.

But how i can retrieve this informations from generationEnd it shows me always that it´s null. How i can print them out?

To get the target isn´t a problem.. but how is it possible to get the source data in this generationEnd method?
My target is to have this output: From Source object is generated this target
