Transient attributes in Xtext grammar [message #1796227]

Hello,

I have a DSL where I'm generating the Ecore meta model from from the Xtext grammar.

Due to a feature request I needed to add a transient volatile attribute in the generated metamodel and implement it in the generated code.

Is there a way to define this directly in the Xtext grammar, so that I can continue to generate everything (including the ecore model) from the Xtext grammar?

Thanks in advance for your help.

Best regards,

Edmundo López Bóbeda

no

- you need either switch to a manually maintained metamodel
- or use the workarounds you can find using google to use IXtext2EcorePostProcessor with the new workflow e.g. https://bugs.eclipse.org/bugs/show_bug.cgi?id=483209

Thank you, I'll look into the IXtext2EcorePostProcessor.
