Anyone got extensive experience with jOOQ and Ktorm? I like sql dsls rather than ORM frameworks. I’ve used jOOQ for years, but wondering if Ktorm might be a good replacement with better Kotlin DSL features… anyone got a view?

Hey folks, I'm getting this

This declaration is opt-in and its usage should be marked with  '@kotlinx. serialization. InternalSerializationApi' or '@OptIn(markerClass = kotlinx. serialization. InternalSerializationApi. class)'

warning on all of my data models marked with Kotlinx serialization's

@Serializable

annotation. Seems like a pointless / incorrect warning as my app works fine despite these warnings, and it would require me to mark every file with the

@OptIn

annotation. I found this Github issue for the problem but the suggested fix to enable K2 mode did not work (already had K2 enabled.) IMO this issue should be re-opened, or does anyone have any other recommendations to fix? Kotlin version: 1.9.0

What's the preferred way to see if a kotlin instant is greater than 7 days away?

Perhaps a silly question, but what is the criteria for

TooGenericExceptionCaught

? It's flagging this as being too generic, but

IndexOutOfBoundsException

seems pretty appropriate. https://github.com/rgmz/NewPipe/blob/75917c7f61cde0537075b3e1c5442cdf27755026/app/src/main/java/org/schabi/newpipe/info_list/StreamSegmentAdapter.kt#L54

I’m attempting to read a file in a Kotlin multiplatform unit test. I don’t have the absolute path to the file, but I do know it relative to my project directory. When I run the test on JVM or macosArm64, the process' current working directory (CWD) is the project directory so everything is easy. But when I run the test on a simulator, the CWD is

~/Library/Developer/CoreSimulator/Devices/C641A553-AA3D-4FAD-4AE-8BDD0E346C5D/data

. Anyone know of a way to recover the project directory when running a test in a simulator?

How can I prevent

LaunchedEffect

running for the first time properly? The current solution is to add a "lock", but it is boilerplate.

Is it a good practice passing

ModalBottomSheetState

to ViewModel?

Is there an example somewhere how parameter injection for a class while at the same time an interface (that is implemented by the class o.c.) is bound to the bean. I have the class

class DokumentMemoryPersistenceAdapter
    (entries: List<Dokument>) : LoadDokumentPort, SaveDokumentPort

and the module

val persistenceKoinTestModule = module(createdAtStart = true) {

    single {
        (entries: List<Dokument>) ->
        DokumentMemoryPersistenceAdapter(entries = get { parametersOf(entries) })
    } withOptions {
        bind<LoadDokumentPort>()
        bind<SaveDokumentPort>()
    }
}

In my test I do the following

@BeforeEach
    fun beforeEach() {
        println("BeforeEach")
        val entries = emptyList<Dokument>()
        val persistenceAdapter: DokumentMemoryPersistenceAdapter by inject { parametersOf(entries) }
    }

    @Test
    fun loadDokumentOkTest() {
        val loadDokumentPort by inject<LoadDokumentPort>()

but as a result I get a message "could not create instance for DokumentMemoryPersistenceAdapter" with a root cause

Caused by: org.koin.core.error.NoParameterFoundException: Can't get injected parameter #0 from DefinitionParameters[] for type 'java.util.List'
	at app//org.koin.core.parameter.ParametersHolder.elementAt(ParametersHolder.kt:41)
	at app//org.codeshards.aktenordner.adapter.outgoing.persistence.PersistenceKoinTestModuleKt$persistenceKoinTestModule$1$1.invoke(PersistenceKoinTestModule.kt:22)

	at app//org.koin.core.instance.InstanceFactory.create(InstanceFactory.kt:51)
	... 81 more

Lines 14 - 22 of my module happen to be the singleton declaration. I also tried to supply the parameter for the injected interfaces along the following sample

val saveDokumentPort: SaveDokumentPort by inject { parametersOf(entries) }

and got the same results. A similar test without a bind option works

class ListPresenter(val a: List<Dokument>)

val presenterModule = module {
    single {
            (a: List<Dokument>) -> ListPresenter(a = get { parametersOf(a) })
    }
}
...
    @Test
    fun listTest() {
        val a = emptyList<Dokument>()
        val listPresenter: ListPresenter by inject { parametersOf(a) }

so I guess the bind option is the problem. Any feedback would be appreciated.

How do you handle validation in the primary constructor? In vanilla Kotlin, it's idiomatic to write

value class Password(val text: String) {
    init {
        require(text.length > 8) { "A password should have at least 8 characters, found ${text.length}" }
    }   
}

I know about

ensure

& co, however the primary constructor cannot return

Either

, so how do you recommend exposing validation? I guess another pattern could be to provide a factory method?

fun String.asPassword() = Either.catch { Password(this@asPassword) }

I am using material navigation and bottomSheet composable in navGraph. Everything working ok so far, except one thing. The bottomSheet automatically closes when I navigate to another destination. I would like to keep it open (remember its state) when coming back to the screen with bottomSheet. Video and code in the 🧵 👇
