with the same call side name

I guess the question is, can I hide the generated setX and getX in java?

or not generate them

You could wrap this in a class that has one constructor taking a list of recipients and one constructor taking in a single one. The class would have a private backing field for the list.

Can an inline class do that?

oh dang, i didn’t realize inline class was experimental 😞

you can disable getter and setter generation using

@JvmField

, though I’m not entirely sure that’d help you in this specific case 😅

You could create a static method that accepts either a single or multiple, with the single just chaining to to the multiple call, but wrapping in a list

neat

inline class Recipient (val recipients: MutableList<String>) {
    constructor(recipient: String) : this(recipient.split(";").toMutableList())
}

guess at that point it doesn’t need to be mutable anymore

nice

is it necessary experimental flag to use contracts ?

I think it's called

mapNotNull

, but you probably found it anyway

Hey guys! I want to develop a system where is possible to “translate” a JSON in another via a web interface. The point of this is give users ability to create those parsers without the programming language. Today I already have this written in NodeJS and using Handlebars (HTML template engine for building JSON sucks 🤮). I’m rewriting some microservices in Kotlin (with #spring) and I’d like your opinion about this system be written in Kotlin? Any suggestion how could I do this? Thread in #server

Let's say I have a Java method:

<T> T doSomething(Class<T> type)

and I want to pass a type that is an array of Class (or an array of any other generic type). I can use a raw type and do

doSomething(Class[].class)

in Java. But calling from Kotlin, I can't do

doSomething(Array<Class<*>>::class.java)

or

doSomething(Array<Class<Any>>::class.java)

or

doSomething(Array<Class>::class.java)

Output is:

Kotlin: Only classes are allowed on the left hand side of a class literal

which makes sense to me, but I don't control the underlying library. Any ideas on how I can call that Java method? It's a hot code path so avoiding allocation ideally.

Works pretty well

Obviously you could just look at the declaration.

Generally the question doesn’t even make much sense. “Variables” are source code constructs.

How to pass an additional java parameter to the java process running kotlin compiler from gradle?

Hello! Is there any channel about Koin?

Oh, I found #koin 🙂

Can someone recommend a libary for representing a grouped list in a recyclerview?

i asked in #reflect but no response, there seems to be issues using reflection on file facades for loading top level functions i can use a fallback to normal java reflection for normal function but i am not sure how i could invoke a toplevel

suspend fun

?

In Java we pass interfaces as callbacks, we can obviously do the same in Kotlin. But is there a cleaner/Kotlin way of implementing callbacks?

Function types, see https://kotlinlang.org/docs/reference/lambdas.html. Looks like this:

fun something(callback: (Int) -> Unit)

In kotlin, I define some static public const like this

object CONST {
    const val SERVER_URL = "<https://storage.googleapis.com/>"
}

object CONFIG {
    const val CONFIG_NAME = "name"
}

Is it a good practice in kotlin? if not, do we have other better ways to define static public const ?

IntelliJ seems to offer `(

$receiver

as Document)` but then says that $receiver is undefined.
