What's the best way to customise jvmargs of the kotlin daemon? Docs recommend using

kotlin.daemon.jvmargs

property in gradle.properties, but how do I use this from command line? For ex. with,

./gradlew bundleDebug -Dorg.gradle.jvmargs="-Duser.language=en -Xmx5g" -Dkotlin.daemon.jvmargs="-Duser.language=fr -Xmx4g"

I see that the Xmx argument that I provided for Kotlin daemon is ignored and instead it's taken from Gradle daemon's jvmargs

$ jcmd 26327 VM.command_line
26327:
VM Arguments:
jvm_args: <redacted> -Xmx5g -Dfile.encoding=UTF-8 -Duser.country=IN -Duser.language=en -Duser.variant
java_command: org.gradle.launcher.daemon.bootstrap.GradleDaemon 7.3.3

$ jcmd 26433 VM.command_line
26433:
VM Arguments:
jvm_args: -Xmx5g -Djava.awt.headless=true -D$java.rmi.server.hostname=127.0.0.1 -Dkotlin.environment.keepalive -ea
java_command: org.jetbrains.kotlin.daemon.KotlinCompileDaemon <redacted>

Is there a way to split a list in two at a given index? I tried

partition

but I can't give it a true/false predicate. I just want to give it a location. I tried

slice

but it only gives me a list after the index. I just wanna be able to slice a list into two parts at a given index and get both parts in one shot (that should be more performant than calling slice twice... right?)

I'm getting

e: Could not find 'main' in '<root>' package.

when trying to build either of the modules in my project. I've set up the gradle config like this

linuxX64("native") {
    binaries {
        executable("prism")
    }
}

How do I send/receive HTTP/2 streams using ktor?

Trying to serialize generic data class having with default value produces empty JSON object

{}

Easiest way to reproduce this issue is to try official generic classes example, add

data

modifier to the class and have default value (eg. in thread) https://github.com/Kotlin/kotlinx.serialization/blob/master/docs/basic-serialization.md#generic-classes I'm using kotlinx.serialization v1.2.2 and Kotlin v1.5.21 Update: All I had to do was read this section of doc 😅https://github.com/Kotlin/kotlinx.serialization/blob/master/docs/json.md#encoding-defaults

Trying use paging 3 lib with filter I cannot explain why it crashed if I don’t insert in between .cachedIn(viewModelScope)

val repoResult: Flow<PagingData<Repo>> = queryFlow.filterNotNull()
        .flatMapLatest { query ->
            repository.getSearchResultStream(query)
        }
        //.cachedIn(viewModelScope) //crash without
        .combine(filterFlow) { page, filter ->
            page.filter {
                it.description?.contains(filter, true) ?: false
            }
        }

    lifecycleScope.launch {
            viewModel.repoResult.collectLatest {
                adapter.submitData(it)
            }
    }

crash is java.lang.IllegalStateException: Attempt to collect twice from pageEventFlow, which is an illegal operation. Did you forget to call Flow<PagingData<*>>.cachedIn(coroutineScope)?

Hello! I tried to mockk a kotlin

flow

so I can bypass one line of code in my class. Basically I need to bypass the

dropWhile

method so it passes the values in flow to the next method. I tried to create mock like that:

@Test
    fun `test mock flow`() = runTest {
        val flow: Flow<Int> = mockk(relaxed = true) {
            coEvery { dropWhile(any()) } returns this
        }
    }

But then i get error

Failed matching mocking signature for left matchers: [any()]

. Is it possible to create a mock that will bypass the

dropWhile

method? Thanks!

Is there a

@IntRange

annotation for kotlin which I can use in kotlin only module? @IntRange works at compilation time right?

I got this crash in my crashlytics today and it doesn’t have the triggering point (where it triggered from).

Fatal Exception: java.lang.IllegalArgumentException
Cannot round NaN value.
kotlin.math.MathKt__MathJVMKt.roundToInt (MathKt__MathJVMKt.java:1132)
androidx.compose.animation.core.VectorConvertersKt$IntOffsetToVector$2.invoke-Bjo55l4 (VectorConverters.kt:172)

It looks like its thrown from the animation framework . Full stacktrace in 🧵

Does anyone know if there is any datepicker for compose desktop? thanks in advance!
