Hi,

I´m trying to open the xtext editor without a file, i have tried to implement different classes like ieditorinput , istorage , idocumentprovider , but i cant make it work perfectly

I manage to open the editor with an istorageeditorinput but when i change something in it throws an excepcion because the model in the editor is null.

I especially have a problem getting the model for the editor without having an ifile.

So how can i open the editor without a file?? what should i extend or implement for this ??

Thanks

Why don't you want an IFile? Where should your model come from or get
stored?

The usualy hook for these things in Eclipse is implementing your own
IEditorInput. So you should maybe have a try in that direction.
If you have an existing model instantiated in an EMF resource, you can
use the org.eclipse.xtext.ui.editor.info.ResourceWorkingCopyFileEdit orInput
as we do in the GMF example.

In the application i'm making i want that when you create a new file opens an editor with a string from an inputstrem buffer that i have in memory and when the user saves the file in the editor there the file is created.

With the IEditorInput i manage to open something like this in the default text editor , but when i tried it in the xtext editor, the ieditorinput since it extends istorageeditorinput the procedure sets the model in null, and when the editor is change it throws a validation exception because the model is null.

I impemented my own documentprovider for my editorinput so that i can create the model for the editor, but there is where im stuck because i cant create the model y in the filedocumentprovider just sets the ifile as the model for the editor.
I found this http://wiki.eclipse.org/Xtext/FAQ that gives a code for creating a model with a inputStream but it didn't work.

Where is the GMF example that you mentioned ??

Thanks

You could try to
1) Using a StingInputStream to load your string into an XtextResource,
similar to
Resource r = resourceSet.createResource(uriOfFutureFile);
r.load(new StringInputStream(contentString);

2) Use an ResourceWorkingCopyFileEditorInput to get an editor input for
that and open an XtextEditor with that input.

The GMF example is shipped with Xtext. You get the code into your
workspace using New->Example->...

Hi there,

We are currently concerned with a similar issue. We also do have a string in memory that we want to manipulate using an Xtext editor. We don't want to have any file interaction. Is there any easier way like just calling the editor with that string?

Cheers

Phil
