Actor kotlin common?

Support
1

Actor is deprecated, I know.
Therefor, I doubt the current version will be ported to Kotlin multiplatform and native.
I cannot do it myself either, as it does internal function calls.
How can I use actor in multiplatform?

Or, what’s the alternative?

Those internal function calls look fairly easy to replace with just a call to launch. Something like this:

import kotlin.coroutines.*
import kotlinx.coroutines.*
import kotlinx.coroutines.channels.*

public fun <E> CoroutineScope.myActor(
    context: CoroutineContext = EmptyCoroutineContext,
    capacity: Int = 0,
    onCompletion: CompletionHandler? = null,
    block: suspend CoroutineScope.(ReceiveChannel<E>) -> Unit
): SendChannel<E> {
    val channel = Channel<E>(capacity)
    val job = launch(context) {
		try {
            block(channel)
        } finally {}
    }
    if (onCompletion != null) job.invokeOnCompletion(handler = onCompletion)
    return channel
}

suspend fun main() {
    coroutineScope {
    	val sendChannel = myActor<String> {
        	for (item in it) { println(item) }
    	}
    	sendChannel.send("first")
    	sendChannel.send("second")
    	sendChannel.close()
	}
}

I ditched the the coroutine start parameter for brevity but if you want to add it, then you can pass that through too, just remember to return a wrapper for the returned SendChannel that will actually start the coroutine. Should be able to adapt LazyActorCoroutine in the source code into a SendChannel wrapper.
