Is there a tidy way to wait for any of`n` coroutines to finish (don’t care which one finishes first, just give me the first one)

[louiscad]

You want a race of coroutines with only one winner, and losers cancelled?

[mp]

No, the others keep going — I just want to respond as soon as the first one finishes and possibly add another coroutine to do yet more work

[mp]

The goal is to keep some k tasks going, but I need to look at each as it finishes to know if I should add more work to do

[louiscad]

@mp You can hack into an actor I think. You can launch 4 (or k) coroutines inside it that then call receive() in a while(isActive) loop before doing work with the received value.

[mp]

interesting, I’ll look into it

It might be worth checking out the source for AwaitAll which does a similar thing: https://github.com/Kotlin/kotlinx.coroutines/blob/master/common/kotlinx-coroutines-core-common/src/Await.kt#L59
