How to check if all references "under" a node are resolved and parsed correctly (validators go crazy)

[goto40]

I want to check if all references under a node are resolved. I need this to prevent running into assertions while validating a model.

Is the following the right way of doing this?

streamReferences(node).reduce((ok, description)=>ok && (description.reference.ref!==undefined), true);

Hey @goto40,

Do you need all (as in: even those in children) references or only those defined on the specified node? If those on the specified node are enough, then your code should do well for that task 👍

Otherwise, you will need to wrap this with a call to streamAst(node).

Thank you @msujew for the clarification (and the prompt response!): I was not aware of this detail.

Is there also a way to check if the whole model was parsed correctly (not only if the references are resolved)? While entering a model I get undefined for model attrbutes which normally are always defined (because the parse is incomplete). My validators then go crazy... Is there a way to deal with this? (apart from checking every single field before accessing it).

You can always look at the parseResult of a document and see whether the parserErrors.length === 0 check holds.

We always had the same problem in Xtext. I don't really think there's a better way to deal with this than being very careful in what you access. Generally, you only undefined checks in validation, scoping and LSP code, but that's already quite a lot. So unfortunately no easy way to deal with this, at least none that I've found.

Thank you very much again for the promp response and the advice / for sharing your experience!
