I have a similar issue, but it's not actually looping (on mac). I click "Update Toolbox App to 4733", it updates, restarts, and then it still says "Update Toolbox App to 4733"

That's what it's doing for me

I guess the difference could be that I have auto-update on?

anyway. closing the app solves the issue for now 😛

I don't have the auto updates enabled and it downloaded and tried to apply it anyway

So if I have subclasses A and B I want to create interface Bar with functions a() and b()

I am using an api which returns various different error types. is their any idiomatic way in kotlin to make a bunch of calls without having to do something like this for each of them?

Copy code

foo.fizz().let { error ->
            if (error.isNotNone()) {
                // log error and maybe worse if the error is bad
            }
        }

With kotlin-reflect, how can I get the annotations of the member property that is inside the list. For example, Say I have following class:

Copy code

class TestData {
    val listData: List<@CustomAnnotation Int>? = null
}

fun checkAnnotation() {
    val member = TestData::class.memberProperties.firstOrNull { it.name == "listData" }
    member ?: return
    val type = member.returnType.arguments.firstOrNull()?.type

}

From that point on, I really have no idea what to do. In debugger, i can see

type

member for

KTypeImpl

, that gives the

annotations

, but seems like I cannot access that? 🤔

oof, this is with the JVM as well I’m guessing?

I believe so.

Coming from Javascript, !== and != are different, meaning they are equal (!=) and their types are equal (!==).

Copy code

File(fileName).forEachLine { Log.d(TAG, it) }

Has anyone looked at using doctest in kdoc like in python, elixir or https://github.com/cscott/JDoctest/ ?

Is it possible to create a generic type parameter that has a default, to help the compiler?

Copy code

fun <T = Any> foo(...)

doesn't quite work

The compiler is saying "I can't infer the type, please specify it explicitly"

LeoColman

11/07/2019, 3:36 PM

I know I could create an overload for it, but I wonder if there's a way

What exactly does the spread operator do? What type is

*arrayListOf(1,2,3)

I was locked out of the kotlinlang slack team for a few months (got a new phone, but the authenticator didn't transfer over). I eventually gave up trying to get an admin to reset my credentials and made a new account. Now that I'm back, I've made that #language-evolution channel, as @louiscad suggested. If anyone wishes to talk about the evolution of Kotlin without making proposals, feel free to hop into there!
