wasn’t there a keep/issue to support it inside when ? what’s the status? i can’t find it 🤔

[genovich]

It seems that tere is no need for it inside when

[karelpeeters]

Counterexample:

when(obj.fetchState()) {
    it.foo is "bar" -> println("hey")
}

[karelpeeters]

I remember there being an issue/keep about this too, can't find it either right now.

thanks!

[genovich]

when(obj.fetchState().foo) {
    is "bar" -> println("hey")
}

val a = obj.fetchState()
when {
    a.foo is "bar" -> println("hey")
}

Hmm they're right that the it stuff would make the lambda situation worse.

[lovis]

val importantNumber = obj.importantNumber()
when {
    importantNumber == 0 -> println("Oh my")
    importantNumber < 0 -> println("This")
    importantNumber > 1000 -> println("is getting")
    importantNumber > 0 -> println("repetitive")
}

another solution would probably be to allow == 0 without a variable or something

[karelpeeters]

is 0 doesn't work?

[lovis]

no

[lovis]

in (0..0) does work 🤔 looks weird tho

[janvladimirmostert]

can't you just do:

when(blah) {

			0 ->  {}

		}

[lovis]

you’re right

[lovis]

facepalm 😅 😅 (now i feel stupid)

[genovich]

val importantNumber = obj.importantNumber()
when (importantNumber) {
    0 -> println("Oh my")
    in Int.MIN_VALUE..0 -> println("This")
    in 1 until 1000 -> println("is getting")
    else -> println("repetitive")
}

[janvladimirmostert]

when is pretty flexible, you can also mix is in there or even do 0,1,3 -> ...
