Xtext DSL embedded editor in a dialog
eclipse-plugin, eclipse-rcp, xtext
Solution
You have to specify the editor's initial contents as the `editablePart` parameter of `createPartialEditor(String prefix, String editablePart, String suffix, boolean insertLineBreaks)`. To obtain your `XtextResource`'s contents as text, save it to a `ByteArrayOutputStream`, then convert it to a string using `toString.`
Problem
I am new to xtext, and i have created a DSL using xtext and i have generated the artifacts, which has generated the editor which has many features like content assist and syntax coloring now the problem is i want to embed the editor inside a dialog. For achieving this im using EmbeddedEditor, i am able to get the embedded editor and place it in the dialog, but the embedded editor is not displaying the contents of the file. The file C:/Eclipse_Work/workspace/runtime_workspace/apa/ex.mydsl contains: ``` import com.ex.test; entity{ element a; } ``` The code in the createcontrol() of dialog is : ``` IEditedResourceProvider resourceProvider=new IEditedResourceProvider() { @Override public XtextResource createResource() { try { Resource resource = resourceSet.createResource(URI.createURI("C:/Eclipse_Work/workspace/runtime_workspace/apa/ex.mydsl")); XtextResource resource2=(XtextResource)resource; return (XtextResource) resource; } catch (Exception e) { return null; } } }; MyDslActivator activator = MyDslActivator.getInstance(); Injector injector = activator .getInjector(MyDslActivator.COM_APAMA_STUDIO_QUERY_EXT_MYDSL); @SuppressWarnings("restriction") EmbeddedEditorFactory factory = injector.getInstance(EmbeddedEditorFactory.class); EmbeddedEditor handle= factory.newEditor(resourceProvider).withParent( composite); EmbeddedEditorModelAccess partialEditor= handle.createPartialEditor(); handle.getViewer().getControl().setLayoutData(new GridData(GridData.FILL, GridData.FILL, true, true, 2, 0)); ``` When i run the project the dialog opens with a editor area but it is not displaying the code present in ex.mydsl, the editor is empty. Please tell me how to show the code in the embedded editor
