[xtext-dev] Persisting xtext document information

[Peter Pedron <Peter.Pedron@xxxxxxxxxxxx>]

Hello xtext developers,

 

with EMFStore it is possible to persist and share EMF model instances.

I was wondering, whether it is possible, feasible or imaginable, to store and restore xtext document structure information (as far as I know this is stored in the AST) along with the model instance, in order that the original xtext document which generated a certain model instance can be restored when loading a model from the store. As you already might have understood, I try to avoid of being dependent on the generated xtext Serializer of the grammar. The use of the standard grammar serializer, when loading a model from an EMFStore, would guarantee the right semantic in the created xtext document, but might produce a different syntax and order of statements compared to the xtext document which was originally used to create the model.

 

Looking forward to your answers and opinions about this topic.
