Hi to all,

I have a ecore-model and want to load a part of this (a subtree) as xtext-dsl.
Is it possible to assign not a resource but a special ecore-element and all it's childnotes to a editor-instance?

Thank you in advance

Best regards
Markus

I think that it is only possible if you override the XtextResource class so that only this special element is returned to the editor.
I think the better way would to slice the model into two seperate resource files and do some linking.

Kind regards

Hi Michael,

ok, thanks for your hint.
Yes, I guess I'll implement it this way.
I only have to implement a kind of navigator to have all the resources in scope (and only this files), with special features.
What's the best way to implement this view, which tree includes any of these resources?

Regards
Markus

Excuse me,
me again....

I don't know if this is the preferred solution either,
because further thinking I guess, I want my complete model to be saved as one ecore-model to have the possibility to use CDO in the future. And the xtext-editor should be only one of three editor types choosable. One editor is a preview-like editor, which should use parts of the ecore-model as well

Any hints?
Thanks for your help

Markus

I heard that there is some kind of mixed resource implementation in the
YAKINDU project. You may have a look at that.

Ok, then I would start with overriding the XtextResource class. Be aware that custom formatting is lost when you only save the created elements in the ecore model. How to serialize and deserialize is described in the FAQ: http://wiki.eclipse.org/Xtext/FAQ#How_do_I_load_my_model_in_a_standalone_Java_application.C2.A0.3F

Kind regards
Michael

Combining CDO and Xtext directly is considered task because they have
different ways to handle object identities.
