I have been reading many articles about MWE2, Xtext, Xbase and Xtend2. Now I want to start migrating an existing RCP project based on EMF, GMF, Xpand, Xtend and oAW.
My problem is that I have a few difficulties when it comes to the right order of implementation.
I wanted to start with the generator as this is probably going to become the easiest part. Introducing Xtend seems to require an existing Xtext grammar though. Therefore defining the grammar by deriving it from the existing ecore metamodel should be the first step, right?
Although I have seen that it is possible to derive a grammar automatically, a manual reimplementation would be preferable, wouldn't it? Later the meta model is then generated from the Xtext grammar, so the current metamodels are going to be deleted then?
And where is the place for Xcore in this scenario? If I need a Xtext grammar, can Xcore still be of help? Or is this only intended for projects where Xtext is not involved on the application side?
Thanks in advance for your help!
