Xtext without code generation [message #901901]

Hi all,

I have designed a DSL in Xtext and would like to grab the AST and map it directly to existing Java Models instead of using code generation. Most of the documentation out there uses code generation. Is there a tutorial that shows how to achieve this?

Thanks in advance,

Karel

Do you mean like an interpreter (interpret the DSL model and make calls
to "existing java model" (what ever you mean by that).

If so, you would just get the XtextResource, get the model and fire away.

Hi Henrik,

Yes, that's exactly what I want to do, to interpret the DSL model into a predefined domain model, instead of generating code.

Thanks a lot,

Karel
