Accessing parser source correspondence for AST elements in standalone setup [message #1805055]

Hi all,

I'm trying to build some static analysis tooling of an XText DSL and I need to access the source correspondences (token start and offset positions in the parsed source file). I can see how one would normally access this information in the formatting2 stubs via the GrammarAccess injections, but I am currently running XText in a standalone setup using a resource set so I am confused how to retrieve this information outside of the formatting2 context.

For the Greetings example how would I find the token start and end offsets of each name?

Hi you can use NodeModelUtils to gain access to the nodemodel. you can also do
org.eclipse.xtext.resource.XtextResource.getParseResult()
and org.eclipse.xtext.parser.IParseResult.getRootNode()

Need professional support for Xtext, Xpand, EMF?
