how to import ast.Keyword

[zrwsmd]

for langium 3.0,i define a class extend DefaultCompletionProvider and override completionForKeyword,but how to import ast

[msujew]

All grammar elements are exported via the GrammarAST object in langium.

so it should like this ,right?

but i override this method in my test project(which langium version is 1.0.1)and code works out well,but when i move same code to my real project(langium 3.0),it seems didn't work out ,a little weird

[msujew]

Yes, that's the correct way to use it. In what way does it break in v3? Can you give more context?

Oh, ok. So it compiles, but doesn't yield the result you expect. I was a bit confused because the original question was about an import issue.

We've had a few changes to the completion logic in v2 of Langium, so there might've been a breaking change in the behavior of the completion. You'll need to debug into the completion provider to see what goes wrong. Remote diagnosis will be pretty difficult.

ok,i get it,it because v3 project can't debug into ,that is why i use old langium project which can debug into,i try to fix it
