(English) Getting oaw TraceComponent working

For openarchitectureware 4.3 there is a tracing extension available. It allows to create a tracing model of your model2model or model2text transformations. For example you can process this tracing model to generate a HTML, XML, ... documentation of your model transformations.

Unfortunately the extension does not work out of the box for me. I'm using openarchitectureware 4.3.1 from the oaw-development pluginbuilder on a mac. Exactly I use 4.3.1.20080910-1400PRD. After a little time of debugging I found a solution to get it working:

• check out project org.openarchitectureware.util.stdlib from the oaw CVS


• switch that projet to branch B_v43 (Team - Switch to Another Branch or Version...)


• hint: the project must be placed in the workspace where the oaw project is located that will use tracing, because a reference to the trace metamodel (trace.ecore) in the plugin is incorrect (it points to ${workspace}/org.openarchitectureware.util.stdlib/src/org/openarchitectureware/util/stdlib/trace.ecore)

workflow:

<workflow>
  <bean class="org.eclipse.mwe.emf.StandaloneSetup" >
    <-- important to get the correct workspace path -->
    <platformUri value=".."/>
  </bean>

  <-- XtendComponent and/or Generator -->

  <component class="org.openarchitectureware.util.stdlib.TraceComponent">
    <traceModelSlot value="tracemodel" />
    <traceName value="trace" />
  </component>

  <component id="traceWriter" class="org.openarchitectureware.emf.XmiWriter">
    <inputSlot value="tracemodel"/>
    <modelFile value="gen/tracing.trace"/>
  </component>
</workflow>

An short example of tracing model2model transformation shows the following snippet:

extension org::openarchitectureware::util::stdlib::tracing;

create Class Class2Table(Class c) :
  createTrace(c,this,"m2m") ->
  setName(c.name);
