next dumb question, how would I concatenate list a to list b, creating list c? (does + work? )

You could make

plotAPI

lazy:

val plotAPI by lazy { PlotAPI() }

anyone have good ideas for lighterweight text editors instead of idea? I try using vim but more suggestions are welcome. Idea is really heavy on my computer

oh, target version is 1.3.20 %)

Out of interest, what use cases do you have? Just things similar to

contains

?

Hi. Are there any mature gradle plugins and/or just command line tools to enforce official coding conventions? Something like eslint for .js, or checkstyle for java?

Hi. I'm following a codelabs course from google "Android Room with a View - Kotlin" and I don't understand the part which the database is instancied with a volatile var into an companion object. Why the

INSTANCE

var is assigned to a

tempInstance

to check if it is null ? and why in the synchronizrd block the

INSTANCE

is assigned to

instance

and the

instance

is returned instead of

INSTANCE

? I missunderstood something i guess.

Congrats @gildor! Please keep it away from Gatwick 😄

Wow! Thanks everyone! I only worry that with quadcopter I will be less helpful for Kotlin community 😂🛸

Damn cool!!! Congrat Andrey!!!!

@gildor congrats. Keep it away from airports and drone patrol eagles

Congrats @gildor and everyone else nominated!

Congrats @gildor! You’d better share some slick drone footage with us once you get it airborne lol

Library author would like to promise that the property is final, as opposed to just read-only.

Which of the nuggets of advice in the pinned thread are people finding works best to convince bosses to try to Kotlin? The business value ones?

Hey there; Just a little question: Why is this an unchecked cast?

val items = mutableListOf<T>()

override fun <U : T> typedItems(): List<U> {
    return items.mapNotNull { it as? U }
}

but this is not?

val oldStuff = mutableListOf<List<*>>()
val newStuff = oldStuff.mapNotNull { it as? ArrayList<*> }

I've just coming from php and it's framework usually provide such boilerplates

Wh… um… I have no idea how to resolve this…

you finds more information about out in https://kotlinlang.org/docs/reference/generics.html

is there a best practice for when to use arrays/lists/varargs as parameters?

decoupling? Do you mean destructuring?

Hi, is there any AOP framework (except Spring) that support Kotlin coroutine yet?

Serious question 🙂 https://twitter.com/wahibhaq/status/1079327710642610176

Can I do a destructuring assignment only into newly declared variables?

Does anyone have experience in working with ktor inside a 'kotlin-multiplatform' project? I cannot run the main method because the MainKt class cannot be found (even though the canonical name is correct)

Might it be planned to make the

{ }

optional when writing a anonymous class?

object  : xyz(...) {   }

Seems like a minor inconsistency since they are optional with 'normal' classes

enclosing the verify block in

runBlocking

doesn't work

is it somehow possible to deal with the following problem.

interface I1{ fun foo(f: (Int) -> Int) }
interface I2{ fun foo(f: (String) -> String) }
class A: I1, I2{
  override fun foo(f: (Int) -> Int){}
  override fun foo(f: (String)-> String){} //same JVM signature
}
