Greetings,
I attended EclipseCon and during the Xtext session (which BTW, was the best in the conference) Sven mentioned that Xtext supports refactoring.
I'm working with Indigo M6 and I've been looking around and I haven't found any trace of refactoring (maybe I'm looking at the wrong place.)
Is Refactoring part of M6 or is it coming with M7?
Many thanks in advance,
-Alex

Hi Ed, hi Maxim
Xbase is not a pre-requisite for the refactoring support.
As the implementation is generic, the RefactorElementNameFragment only
produces plugin.xml entries to register. In the Domain Model example,
the generated classes provide support for the derived JVM model (the
Java view on the model, used for linking) and are produced by the
XbaseFragment.
Documentation will follow soon. Here are a few pointers
1) Enable rename refactoring by using the RefactorElementNameFragment.
Remember updating the plugin.xml manually.
2) Services you might want to customize:
IRenameStrategy: Performs the rename on the semantic level. Customize
e.g. if your names are not stored in a String EAttribute "name"
IDependentElementsCalculator: provides the elements whose names
depend on the renamed element, e.g. inner classes if the containing
class is renamed.
3) In order to update external references, the referring models (and
especially the references) must be indexed. See the Xtext docs on Scoping.
4) For references from non-Xtext resources, you have to bind an
EmfResourceReferenceUpdater by implementing an IResourceServiceProvider,
similar for what we do for Ecore.
Hope that helps you get started
