Alright I know this isn t an arrow meta question specificall kotlinlang #arrow-meta

Alright, I know this isn't an arrow-meta question specifically, but I figured the folks here might be able to help: Does anyone know how to grab the package path where a class is located from a

KtClass

? Closest I've been able to get so far is

ktClass.parent

, which (assuming the

KtClass

sits at top level), I believe gives me a

PsiElement

that represents the file that the class sits in. However, even there, I can't see any way to get the package path where the class resides. I'm not seeing anything in the methods of either

KtClass

PsiElement

that would be helpful here. Any ideas?

For context here, I'm trying to make an arrow meta plugin that does some codegen with

Transform.newSources

-- and in the generated code, I need to be able to add an import statement for

KtClass

in question.

Hi @Nathan Bedell, if you use ClassDeclaration from the quote package you have access to a

descriptor

property in which you can get the package contained

https://meta.arrow-kt.io/apidocs/arrow-meta/arrow.meta.quotes.classorobject/-class-declaration/descriptor.html

If you are using plain KtClass you need to get the class descriptor with

org.jetbrains.kotlin.psi.KtPureElement.findClassDescriptor(bindingContext: org.jetbrains.kotlin.resolve.BindingContext): org.jetbrains.kotlin.descriptors.ClassDescriptor

or similar utility methods

Thanks @raulraja. I think I was actually doing the right thing before -- my issue was my test file didn't have a

package

declaration -- so of course all of the methods that should have returned a package were coming up empty!
