Hi

I have already had an existing xtext project where I defined my metamodel and grammar, and it works fine.
now I need to develop xpand project for code generation, so who I can pass the AST (Abstract Syntax Tree) that generated when using Xtext DSL editor and my DSL to the new xpand code generator project.

I am using Eclipse Mars 2 (4.5.2)
Xtext 2.9.2
Xpand 2.1.0
MWE 1.3.13

You should consider to use Xtend for code generation.

In the case you really want to use Xpand, you have to invoke the Xpand generator from within the IGenerator. There, create an XpandExecutionContextImpl with an EmfRegistryMetaModel and create a XpandExecutionContextImpl.

The IGenerator gets an EMF Resource, which contains the AST.
