Using code generation with Xbase, instead of JVMinferrer [message #1758110]

Hi,
in a new grammar i'm taking advantage of most Xbase rules, and xtext generates me an AbstractModelInferrer for it.
Is it possible to use a generator instead of that inferrer?
I have a lot of references that won't be present at infer time and i think a generator would be more suitable for my needs.
Thanks for your help, it's very appreciated.

i assume you have a basic missunderstanding

xbase is JvmModelInferrer + JvmModelGenerator + XbaseCompiler

=> there is actually a generator.

how it depends on your usecase if

- you adapt the JvmModelGenerator (Xbases IGenerator)
- adapt xbase itself and introduce new concepts (XbasetypeComputer + XbaseCompiler)
- or can do it with the inferrer any way.

By 'generator' you mean a template based generator with Xtend? You could bind a new instance of IGenerator and inject both the JvmModelGenerator (which was bound by default) and the template generator and delegate to both. When you have to compile Xbase expressions from there things become a bit tricky, but basically you would inject and use the XbaseCompiler.

Thanks! By generator i mean an "AbstractGenerator" that is automatically created by the wizard.
I'll try your approach creating and binding a new Generator, used for some expressions and the inferrer for the XBase expressions and i'll see how it goes.
Thanks again!
