Ecore model generation - merge custom and generated java code [message #899040]

Hello,

Usins xtext 2.3, I would like to modify the generated java code for my grammar. I know I can use a PostProcessor to modify the model but I would prefer to use the merge feature of EMF described here www.informit.com/articles/article.aspx?p=1323360&seqNum=4 using @generated markers. I would customize the generated code and Xtext/EMF would merge grammar modifications in the java code.

If I remove the directory cleaner from my mwe2 file, the generated java classes are not modified when I change my xtext file and launch the workflow.

Do you know if this merge feature is supported by xtext and if so how can I achieve it ?

Thanks,

Denis

hi,

what kind of changes to you want to make?
what about switching to a manally maintained metamodel.
if you want not todo the changes inline there is
generation gap support with org.eclipse.emf.mwe2.ecore.EcoreGenerator
