How to get the type of a tastyquery.ast.Trees.Tree?

[civp]

There's a member tpe in the class Tree, but the method calculateType doesn't seem to be implemented.

protected def calculateType(): Type = throw new TypeComputationError(this)

Is there currently a way to get the type of a Tree?

Hey, thank you for your question. Types still need to be implemented (as of February 2022).

One exception is the type of a ValDef tree, where that ValDef comes from the parameter of a class.

In SymbolSuite.scala, you could get the field of some class with this code:

test("get-type-of-parameter") {
  val ctx = getUnpicklingContext("simple_trees/ConstructorWithParameters")
  val theValPath = SimpleName("simple_trees") :: TypeName(SimpleName("ConstructorWithParameters")) :: SimpleName("theVal") :: Nil
  val theValSym = followPath(ctx.defn.RootPackage, theValPath)
  val theValType = theValSym.tree.tpe
}

Thank you for your reply. I'll be looking forward to the implementation.
