Extract ATL model to ATL text - reloaded [message #106700]

Hello,

I'm working on a higher order transformation which targets ATL and, in
order to check it, I'd like to see the actual generated ATL code (extract
it from the ATL model) and tried doing so using an ant file.

-------------------------------------------------
Scenario 1: Eclipse Ganymede (ATL 2.02), AM3, TCS
-------------------------------------------------

1.1

*********** build.xml -save section ******************
<am3.saveModel model="ATLOutput" path="${targetModelText}">
<extractor name="ebnf">
<param name="format" value="ATL-TCS"/>
<param name="indentString" value=" "/>
<param name="serializeComments" value="false"/>
</extractor>
</am3.saveModel>
*****************************************************

Exception: could not read property "isNoDefault";
I use the ATL-0.2.ecore metamodel as target in my transformation, the
element isNoDefault is in ATL-0.2-TCS.ecore, therefore it can't find it
(this happens when it reaches MatchedRule, the module, import and
libraryRef is written ok).

1.2

"AM3 Perspective -> Extract ATL-0.2 Model to ATL-0.3 File" doesn't produce
anything (on the target file, with an .xmi extension).

----------------------------------------------------
Scenario 2 - Eclipse Galileo - ATL 3
----------------------------------------------------

I really didn't find some specific atl saveModel section with an
extractor, so, I tried figuring it out, don't know if this is correct:

*************** build.xml *************************
<project name="project" default="default">

<property name="atl.launcher" value="Regular VM (with debugger)" />

<target name="default" depends="modelsLoading">
<atl.launch path="transfo/Tocl2Atl.asm">
<inModel name="IN" model="ToclInput" />
<outModel name="OUT" model="atlFile" metamodel="ATL" />
</atl.launch>

<atl.saveModel model="atlFile" path="output/out.atl">
<extractor name="ATL"/>
</atl.saveModel>

</target>

<target name="modelsLoading">
<atl.loadModel modelHandler="EMF" name="tocl" metamodel="MOF"
path="metamodels/tocl.ecore" />
<atl.loadModel modelHandler="EMF" name="ATL" metamodel="MOF"
path="metamodels/ATL-0.2.ecore" />
<atl.loadModel modelHandler="EMF" name="ToclInput" metamodel="tocl"
path="input/ocl_rule.tocl" />
</target>

</project>
**************************************************

Exception:org.eclipse.m2m.atl.core.ui.vm.asm.ASMModelWrapper cannot be
cast to org.eclipse.m2m.atl.core.emf.EMFModel.

I also found on the newsgroup suggesitons to use Xpand from oaw, didn't
really try it, especially because the extractor for ATL is already
implemented in ATL 3, can be used in ant files, without any am3, tcs...

So, whether it is for ATL 3, or for the older version, do you have any
suggestions?

Best regards,
Cosmin

At this time, ATL ant tasks does'nt allow use of multiple VMs for one
ANT project, as models are not loaded under the same format.
And the ATL Extractor has only been defined for EMFModel
(ASMModelWrapper are used by RegularVM) - to fix compilation performance
issues.

So here, you have to specify no atl.launcher property (EMF specific VM
is default for ant tasks), or:
<property name="atl.launcher" value="EMF-specific VM" />

Best regards,

William

Hello,

Thank you for your help William, I've made the changes and overpassed the
initial exception. However, when it tries to save the model using the ATL
extractor, I come against this exception:

could not read property "isNoDefault" of element
org.eclipse.emf.ecore.impl.DynamicEObjectImpl@178fd24 (eClass:
org.eclipse.emf.ecore.impl.EClassImpl@11c4d14 (name: MatchedRule)
(instanceClassName: null) (abstract: false, interface: false)) :
MatchedRule

It's actually the same exception as in Scenario 1 (1.1 trial), in my first
post. Should I be using the metamodel for ATL 3? So actually, the
extractor uses the ATL-0.2-TCS (there I found the property isNoDefault, in
the MatchedRule). The MatchedRule in ATL-0.2 has the isDefault property,
and I set it to true in my transformation, but that didn't change a thing.

Thank you!

Best regards,
Cosmin

The metamodel you should use for the transformation is the following:
http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.m2m/org .eclipse.m2m.atl/plugins/org.eclipse.m2m.atl.common/src/org/ eclipse/m2m/atl/common/resources/ATL.ecore?root=Modeling_Pro ject&view=markup
