Generate QVTo-file [message #1717616]

Hi

Is it possible to generate a QVTo-transformation by means of another QVTo-transformation?

I wrote the following transformation:

modeltype IMP_OCL uses 'http://www.eclipse.org/qvt/1.0/ImperativeOCL';
modeltype OCL_ECORE uses 'http://www.eclipse.org/ocl/1.1.0/Ecore';
modeltype QVTO_EXPR uses 'http://www.eclipse.org/qvt/1.0.0/Operational/Expressions';

transformation GenerateHelloWorld(out o : QVTO_EXPR);

main() {
    object OperationalTransformation {
    	eOperations := object EntryOperation {
    		name := 'main';
    	};
    };
}

When I save output model into xmi-file, it works fine. But when I try to save it into qvto-file, the latter one isn't created at all.

Also when I save qvto-file as xmi-file, it works. But I can't save xmi-file as qvto-file. Is it possible?

It seems that qvto-generation isn't supported:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=377320

It would be great to have such a possibility...

Hi

*.qvto is a text file extension.

Some contributions have used *.qvtox as the XMI equivalent, but AFAIA
this is not yet supported by the code.

The forthcoming Pivot-based code uses *.qvtcas/qvtoas/qvtras for
QVTc/QVTo/QVTr AS (XMI).

Denis,

I am nearing completion of implementing the missing save() Funktion.
Would you be interested in testing it?

Best Regards,

Uwe

Hi Uwe,

It will be interesting to test and possibly integrate such functionality.

Can you please share link or post source to dev group (qvto-dev@eclipse.org).

TIA,
Sergey Boyko.

Hi

It will save time in due course if you attach, preferably a GIT patch,
to a Bugzilla and sign the CLA to indicate your formal willingness tyo
contribute.
