it would return

null

. Good catch

I modified it again to what it was before

why isn't this all in a thread??

Slack is like IRC.

Hi everyone. I am so glad to join this workspace

this works, is it the correct way to do it?

interface Animal<T : Animal<T>> {
    val id: String
    fun withSound(sound: String): T
}

data class Dog(
    override val id: String
) : Animal<Dog> {
    // does not work
    override fun withSound(sound: String): Dog {
        TODO("Not yet implemented")
    }
}

I don't see the second override working as you cannot have a method with the same signature twice

it works in your second example as you only have one method there

i don’t need it twice

i just need the second one

i think your first

Animal

interface states that ‘all animals need to be able to supply any animal, given some sound’. I think what you want to say is that ‘all animals can be configured with a sound’? or is it ‘all animals can be transformed into another animal if they are given a sound’? i think that there’s something not completely right about the model you’re using, but it’s hard to tell without a bit more background about what problem you’re trying to solve

i want this: “‘all animals can be configured with a sound’”

I see that @mikhail.zarechenskiy has updated the eclipse plugin for 1.4 release, any plans on releasing or also updating for eclipse 4.16 or 4.17 release, because the current eclipse version is eclipse 4.7

anyone successfully published to Jitpack using kotlin 1.4.0? I see in the build it keeps using 1.3.72 for some reasons..

Good Evening,

Any idea why this may happen? Posted in #gradle

I tried using kotlinx-datetime for kotlin native LinuxArm32Hfp and got a compilation error. Anyone know if this target is supported yet and if not it will be at some point? Or if there is some way to still use the library?
