Custom XtextResource or URIConverter? [message #636567]

I have defined a grammar on top of an existing model.

I would like to include the XtextEditor as a page in an existing editor (FormEditor), now my problem is that what should be the XtextEditor input represent a sub part of another Resource.

I give you an example:

I have a model: MyCustomObject
which is stored using XMIResourceImpl.

Now I have a grammar defined for: MyCustomExpression

which is a subpart of MyCustomObject. (so myCustomExpression.eResource is XMIResourceImpl)

How can I create a XtextEditor inside a FormEditor and be able to link the XtextEditorInput to the "part" of MyCustomObject relative to MyCustomExpression?

Should I use a URIConverter and play with the createInputStream/createOutputStream ?

Or define a new Resource ?
How can I obtain programmatically an instance of XtextEditor ? Should I use: Activator.getDefault().getInjector() ?

Thx
Patrick

I'm also interested in this.

Any suggestion would be appreciated.

Thanks,

Aclipse editors are quite heavy weight and kind of hard to reuse in
other contexts. You can have a look at the GMF example shipped with
Xtext which demonstrates how to embed such an editor in a popup window.

It should be easier to customize a StyledText widget with Xtext based
services such as code assist and syntax highlighting. Have a look at the
plugins
org.eclipse.xtext.ui.codetemplates
and
org.eclipse.xtext.ui.codetemplates.ui
where we integrate Xtext based editing in the Eclipse prerference page
for code templates.

I would like to use the xText editor to edit a subelement of a model (For instance, Model.Package.Class).
I want to create the Model and the structure with a different editor (maybe GMF), and to edit what's inside the Class with xText.
I'm thinking of creating the xText editor by using Class as the root model element.
When I press Enter on a Class inside the GMF editor, I want the xText editor to open so that I can edit what's inside the Class.

What do you think would be the easiest way to achieve this?
Do you think that temporary xText files are required?
Should I try to extend XTextResource? I've also read something about an UriConverter.
I would appreciate any suggestions.

Thanks,
Lucian

Once again, have a look at the GMF example. We have a popup editor there
that allows to edit a section of a model textually.
