Any idea why abstract class having functions with default argument doesn't generate their corresponding $default(...) synthetic method in Kotlin Multi-Platform?

Here is the problem in detail: https://stackoverflow.com/questions/59919778/expect-abstract-class-with-default-argument-doesnt-generate-default-static-met

as far i understand a single thread can have n number of co-routines , in other words n number of callback for the fun if for example you want to handle multiple request (where intensive crypto are done for process) and assigning each thread a request makes sense rather via callbacks and a single thread. From a thread in #general

i dont like coroutines,inheritance and operator overloading. would prefer kotlin over java but on other hand would never prefer kotlin over golang.

@Chills please start a thread instead of messaging here directly

Please, how do i write a coroutine test for a function like this..

override fun createWallet(request: CreateWalletRequest?, responseObserver: StreamObserver<Wallet>) {
        GlobalScope.launch {
            val wallet = async { return@async this@WalletService.repo.get(1) }
            responseObserver.onNext(wallet.await())
            responseObserver.onCompleted()
        }
    }

The code within the GlobalScope.launch runs well, i can print it out... the onNext(value) is called and i can't seem to get the value from my test... What i've tried but doesn't work...

@ExperimentalCoroutinesApi
    @Test
    fun `createWallet should pass`() = runBlockingTest {
        //Arrange
        val responseObserver = mockk<StreamObserver<Wallet>>()
        val slot = slot<Wallet>()

        every { responseObserver.onNext(capture(slot)) } just Runs
        every { responseObserver.onCompleted() } just Runs

        val wallet = Wallet.newBuilder().setUserId(2).build()

        coEvery { repo.get(1) } returns wallet

        val request = CreateWalletRequest.newBuilder()
            .setWallet(wallet)
            .build()

        //Act
        this@WalletServiceTest.walletService.createWallet(request, responseObserver)

        //Assert
        assertThat(slot.captured).isNotNull()
    }

if this on purpose?

class Test{}
 class Another {
   fun <E> test2(test: E) = test.test()
   fun <E> E.test() = if(this is Any) 
     println(this.javaClass.simpleName) else {}
 }
 Another().test2(
   Test()
 )

prints Test

class Test{}
 class Another {
   fun <E> test2(test: E) = test.test()
   fun <E> E.test() = if(this is Any) 
     println(javaClass.simpleName) else {}
 }
 Another().test2(
   Test()
 )

prints Another

and sorry for the formatting, apparently the new slack code block still defies me

I am making a test factory for a model( I do not want to generate stubs) so i have something like

fun makeCashPeriod(): CashPeriod {
        return CashPeriod(period = randomString(), status = randomString(), type = randomString(), numberOfEntries = randomInt(), isCashCountRequired = randomBoolean(), mutationBalance = randomString(), canBeClosed = randomBoolean(), remark = randomString())
    }

hello how i can use bitmap to display imageview with kotlin

Hi everyone, does someone knows how to make avro generated schema to have nullable fields?

if I change the invocation to

order?.getParameters()

it works fine but intellij complains

Unnecessary safe call on a non-null receiver of type Order

is there a way to tell kotlin that that function might return null?

without changing the source code as it's generated by avro so it'll be overwritten

curious if there has been any work on: https://youtrack.jetbrains.com/issue/KT-35147

Happy universal palindrome day everyone! https://susam.in/blog/universal-palindrome-day/

For a while now, during assembly, the task ":kaptGenerateSubsKotlin" fails with a "java.io.IOException: Cannot run program "C:\Users\joey_\AppData\Local\JetBrains\Toolbox\apps\IDEA-U\ch-0\193.6015.39\jbr\bin\java": CreateProcess error=206, De bestandsnaam of -extensie is te lang" (error says path is too long in Dutch), but often when i stop the daemon and rerun the assembly, it works again, but this doesn't always happen. Is this a know error with a simple fix? I already enabled the Windows 10 "long file name" feature

Can confirm the reason IntelliJIDE didn't work for me didnt work well with NTFS-3g

tbh you can write you're own kotlinsh json parser 🙂 writing json parser is far easy than xml.

Hi, is there someone from Argentina who bought effective kotlin book (paperback)? I want to buy it but I don't know if I can get it from here.

When escaped characters are confusing, like in this example: #KotlinTips https://t.co/kEt6gofkbB https://t.co/DIXIkbuQ0b Twitter
