feat: inheritance references for classes and interfaces

[Angelika12]

Classes are parsed as ClassDeclarations - anyhow, I don't find the classes, where a specific class inherits from.

[buehler]

What do you mean by inherits from?

class A {}

class B extends A {}

so the ClassDefinition of B should contain a reference to A ?

[Angelika12]

Yes, exactly. I would need the reference from B to A. The background is that I'm building a programm, which parses a set of Typescript files and generates a class diagramm out of it (for documentation purposes).

Ok, so I thought about this and found the following problem: during the parse step, I can only parse the name of the type that a class extends from. I don't have the exact knowledge about the type. This exact reference can only be done when the whole declaration index is used. Then I could parse the name that is used with the given import to actually get the type reference.

I also would love to see this feature added. And unfortunately, it's even a showstopper for me. I can't think how I can work around it with the current features.

For me I'd just be happy to have all the tokens which are following the extends keyword. That is, this statement would be a perfect fit:

I can only parse the name of the type that a class extends from.
