Hello,
I constructed a DSL using xtext. I have a number of text files written in that DSL and I want to transform them into a single model that conforms to another metamodel. AFAIK xtend dosn't support model merging (each text file is considered a model corresponding to the my dsl metamodel) to merge all the files to one or multiple input model to one output model to do the merge on the transformation.
So I think epsilon can help me, but since my models are not ecore based I need the xtext reader class to read the models (org.eclipse.xtext.MweReader). But since epsilon doesn't use a workflow I am wondering if some one can think of a way to read my dsl files (models) so I can use them as inputs for Epsilon.
Regards,
Horacio Hoyos

Hi Horacio,
I must admit I'm not very familiar with MWE and only have limited
experience with Xtext. I'll have a look at this and try to put together
an example that shows how to use textual Xtext-based DSL models in
Epsilon within the next few days.
Cheers,
Dimitris

Dimitris,
My DSL files are not EMf resources, they are just plain text files. The generator project created as part of a xtext project is used to read your dsl files and transform them to text. In the generated workflow the dsl file (model) is read with:
<component class="org.eclipse.xtext.MweReader" uri="${modelFile}">
<!-- this class will be generated by the xtext generator -->
<register class="org.xtext.example.DieselStandaloneSetup"/>
</component>
So it seems that that java class is needed to "interpret" my dsl files and load them to a interpretable xmi instance to use in the transformations.
My guess is that I have to make an ant file to run my transformations (and not a configuration) and include the above component to access my dsl files as models?
Regards,
Horacio
