Hi

Acceleo is an M2T (Model to Text) transformation tool/language. QML is a textual language so if you have a model then you can use Acceleo to convert to it.

Creation of QML text from a model seems like a fairly obvious thing to do so I recommend a little time searching for something to re-use before doing it yourself.

Hi

Perhaps you misunderstand Acceleo and M2T. Acceleo is a tool, like a Java compiler, that supports a language, like Java, in which you can write programs to tackle interesting problems.

Your problem as I understand it is to convert something, possibly a QML model, into QML text. You can program this model-to-text conversion in Acceleo (or Java).

I suspect that you expected Acceleo to auto-implement the conversion program. One day that may be possible, but only if
- your source, possibly a QML model, has a full machine definition, possibly an Ecore metamodel
- your target, QML text, has a full machine definition, possibly an Xtext grammar
- the source to target semantic relationships are simple enough to be captured by the Xtext grammar, or specified in some other way, possibly an M2M

My recommendation was to search for some QML tool support that has already done this. Of course if you are a primary QML developer you may want to exploit tools such as Xtext.

Hey;

I'm really grateful for your explanation, but if i create a model using EMF, ( as far as I knw it's able to generate a script written in java from a model) will it be able to generate a .qml file? ( I'm sorry if I sound stupid but this is my first time with Acceleo/Eclipse and EMF)

Kind regards

Hi

The Ecore model to Java conversion is defined by the JET M2T language with the help of many genmodel support Java classes in the org.eclipse.emf.codegen.ecore plugin.

You could write JET template(s) for Ecore to QML. You could refine the genmodel classes. But you'll probably find Acceleo easier.
