Hi,

I have an XMI file derived from a DSL metamodel.

I would like to convert it back to the DSL, i.e myfile.mydsl.

Is this possible using Eclipse, without doing this programmatically ?

Hi

You haven't told us what the relationship is between the DSL and the XMI.

If you have the 'trivial' relationship whereby Xtext treats the DSL source text and its underlying parsed EMF model as equivalent, then you should be able to open the XMI with your DSL editor see the serialized text and copy/save it as text.

If you have a non-trivial relationship, then the programmer of your forward conversion from DSL to XMI may also program the reverse conversion from XMI to DSL so that you can open in your DSL editor as above. (This works for the OCL, QVTc, QVTi, QVTr editors.)

You may get some inspiration from the following blog post: https://blogs.itemis.com/en/combining-emf-models-with-xtext-dsls

It contains (among others) an example implementation for:
Quote:

An additional feature could be to add Xtext serialization support to EMF models; when the user edits an EMF element and saves the *.emfstatemachine file, we want that the corresponding *.statemachine Xtext DSL file is automatically generated.
