Here. First, I just want to say that I love kotlin. It has made my and my team's life easy on so many occasions. I use kotlin in production, on server side. I have never had any issues with Kotlin! I love it! So, I have a library written in kotlin, that is wrapping around apache httpclient. It uses coroutines and provides convenience and auth functions around our stack. I use kotlin

1.2.41

in the library. Strangely, when I upgrade the library to

1.2.50

and above, the dependent projects (spring boot) cannot see my library. gradle command line builds fine. Only IntelliJ does not recognize the library functions. Am I missing something?? The only change being upgrading the kotlin versions from

1.2.41

to

1.2.60

AND upgrade coroutines from

0.22.5

to

0.24.0

Is it possible to destruct a list into variables e.g.

val item1, item2, item3 = list

If so, is it possible to make it do a getOrNull?

How could I implement an "async" (for Deferred<Boolean>) or/and?

blegh, does kotlin provide a nice way to get the platform I'm running on? I know that javascript and native make that question more complicated, but I'm annoyed by

getProperty("os.name")

, does kotlin have something better?

Hello guys. Not really sure where to post this, but i feel like non-override

val person: Entity? = null

should throw a warning in IntelliJ. Or do you find any case where it's OK?

fun check(params: Map>String, *>, ???): ???
check(params, String) // return a String
check(params, String?) // return a String?

what to put instead of

???

?

the result is the same String.Companion

Type mismatch: inferred type is String.Companion but String was expected

For curiosity, why extension of array return list? It does not make sense to me. intArrayOf(1,2,3).filter { it > 1} = List<Int>

filterIndexed

Is there a neat way of accessing a private/internal field from an inline function in a class? I'd rather not make the field public as it's internal state that shouldn't be poked from the outside.

by testing a public/global one that uses it

The simplest guideline is to not inline anything unless it’s something the compiler needs or the IDE suggests. ie. if you are using generic reification you will need to inline that method. The JVM JIT is pretty good about figuring out what to inline, and unless you are very careful inline methods are more likely to hurt performance than help.

I’m not experience with compiler/type-checker implementations, but I’ld be interested in learning about what is going on.

If I have an extension function that takes in

One applies to classes, the other to types 😛

anybody got an idea what im doing wrong?
