Should Kotlin libraries use Maven scope

provided

for their dependency on kotlin-stdlib?

Why

.

is not allowed in kotlin function names even when backticked? Is there youtrack for this? (IIRC scala and groovy can have dots.)

The generated code performs an explicit null check before calling

substring

, so you'd get a different exception in that case:

@NotNull
   public static final String getDesc(@NotNull Class $receiver) {
      Intrinsics.checkParameterIsNotNull($receiver, "$receiver");
      if (Intrinsics.areEqual($receiver, Void.TYPE)) {
         return "V";
      } else {
         String var10000 = createArrayType($receiver).getName();
         Intrinsics.checkExpressionValueIsNotNull(var10000, "createArrayType().name");
         String var1 = var10000;
         byte var2 = 1;
         if (var1 == null) {
            throw new TypeCastException("null cannot be cast to non-null type java.lang.String");
         } else {
            var10000 = var1.substring(var2);
            Intrinsics.checkExpressionValueIsNotNull(var10000, "(this as java.lang.String).substring(startIndex)");
            return StringsKt.replace$default(var10000, '.', '/', false, 4, (Object)null);
         }
      }
   }

if you tell me what that acronym means!

so do more people use kotlin now for android than for java?

Hey Kotlin community. Could anyone help me understand why

x::class

produces

KClass<out T>

instead of just

KClass<T>

in the following snippet?

class Test<T : Any>(val x: T) {
  fun type(): KClass<T> = x::class // doesn't compile bc types don't match!
}

And a follow-up question, is there any way to make this compile without having to cast the result of

x::class

to

KClass<T>

?

how would you make sure then

type

represents `x`'s type?

Hi everybody, I'd like to create a community powered multiplatform version of the Java standard library. My aim is to create a library that is usable in the same way on every Kotlin backend. I've setted up the repository ( https://github.com/lamba92/kotlin-extra-library ). Any help is very much appreciated! Posted in #library-development

Hi,I deployed my library in github private repository.and i implemeted in my another android application with many versions release.Today i updated my library and pushed into repositpory released new version but unfortunately it unable to sync gradle getting error like "ERROR: Failed to resolve: com.github" .i used jitpack also and meaven also. but unable to resolve..Please help to resolve issue. Thanks.

just want to confirm this kind of code is ok

when (foo?.bar) {..}

- I can't see why it wouldn't be but just want to make sure about the null

Hello, why is there no autocast in this case? Seems like a bug to me

open class Animal

class Dog: Animal() {
    fun bark() = println("Huf huf!")
}
class Cat: Animal()

fun main() {
    val numbers = arrayOf(1, 2, 3)
    foo(numbers, Cat())
}

fun foo(numbers: Array<Int>, animal: Animal) {
    if (numbers.isEmpty()) {
        return
    } else if (animal !is Dog) {
        return
    }

    println(animal) // no autocast here
}

Hello, doesn't this line of code add a Pair to the mutable list?

val list = mutableListOf<Pair<String,String>>()
....
list.add(Pair(foo,bar))

But in my case this doesn't add a new item to the list. All this is done inside a coroutinescope from a object of a class which has the above code.

Hi Anyone ca help me with OKR ?

does any language have a swap operator? like

<->

or something? would be cool if kotlin had one. NVM just gonna use

also

I am recruiting for a number of Senior Software Engineer #jobs in #Melbourne. Java, Kotlin, Microservices, etc. Permanent roles paying $100-$140k base + super + ESOP. Sorry if this is the wrong channel for this!

what is significant that prevents kotlin from allowing

..

operator to create descending ranges like

9..5

? Shouldn't it be somewhat trivial to put into the code to create one or the other based on the higher value? is it simply ambiguity?

Why is it extension functions are always shadowed by class functions? It would be really useful to be able to override them in narrow scopes

Hi guys. I got a strange situation with

suspend

function which I can't solve: I got function

suspend fun one()

which executes some code and then calls a function that accepts a callback function as a param. But, this param function is not suspend. The issue is that I need to call another suspend fun from that callback param function. Here's an example:

suspend fun one() {
    doSomething()
    funWithNonSuspendCallback("data") {
        two() // I need to call it from here but this is not suspend scope anymore
    }
}

suspend fun two() {
}

Do unsigned numbers (

UByte

,

UShort

,

UInt

&

ULong

) have their boxed versions cached in a reasonable range? On Android, all signed numbers are cached from -128 to +127 (i.e. full

Byte

range, and part of

Short

,

Integer

and

Long

)

In/Out variance declared on the type, not at the use site, is a huge win.

I want to use

Contract

in my lib, to infer non-nullability in a nullable value, and let users use it. However I don't want to force the user to use the compiler option. Is this possible? Or should I wait for contracts release?

Hey 🙂 can I

map

a

SortedSet

without transitioning the whole thing to a

List

?

@Casey Brooks Any way to fix that?

Use

@JvmName

is there a way to reference a top level fun that has the same name as a local variable? usually I would do

Class.funname()

, however there is no class here
