Hi

I am a beginner in Java and Xtext world, I have defined my DSL grammar and generate all my DSL artefacts. and now am trying to develop a code generator.

so my question is how to call the AST (Node Model or parse tree that generated after writing a program using my DSL) parameters in the xtend file, so I can configure my code generator to parse the generated AST and generate a customized template.

and to inspect the generated AST, is it better to contribute in the xtend file or the serializer file

and is there any simple tutorial that you can refer that help in my task

Best Regards
AYMEN

Hi,

i am not sure if i get your question. you may have a look at https://www.eclipse.org/Xtext/documentation/103_domainmodelnextsteps.html#tutorial-code-generation.

to have access to the node model use the NodeModelUtils class (you usually should not need to to that in the first place)

Need professional support for Xtext, Xpand, EMF?
