hi all, looking for a sr. android dev with Kotlin experience and familiar with camera api. Need help with a project for a client. If interested please DM me, thanks!

fun a() = 1

class A() {
    fun a() = 2

    fun printA() {
        println((::a)())
    }
}

fun main(args: Array<String>) {
    A().printA() // Prints: 2
}

Is there a way I can reference top-level function instead?

Hi! I am having a problem with chosing an extension function in a

when

block. The type does not get inferred... here is a little reproducible gist: https://gist.github.com/noncom/ea3e57e676a799efe2943a34b06f2986

I noticed a commit in Kotlin repo for inline class feature. Seems interesting. Is there a spec for it?

How does one run kts at runtime

Anyone got any idea how to get kotlin JSR registered?

Hey 🙂 does anyone know a cool kotlin JSON parser? (read only)

you can’t use a typealias to set a conflicting projection variance, though

Hi guys. Can I obtain default value for generic type T? I need something similar to

T variable = default(T)

in the C# My first try in kotlin:

data class Node<K>(val key: K)

class Container<K> {
   var head = Node<K>() // err here, I have to specify *key* prop in the node ctor, but how?
}

What can I use?

why does foo not compile?

@karelpeeters yes, I know about how static denies inheritance in Java and such.. but what about such a situation? https://gist.github.com/noncom/921a4e322e89424c961eae54bcac41e4

I was trying to come up with a usecase 😒imple_smile: I was thinking you could then get the companion object from the

KClass

and you'd know that it implements the factory interface. But yes, all this is very messy and contrived, you'd be better off just passing around a lambda instead of the

KClass

.

Hey everyone! Is anyone interested in a remote Kotlin gig? The client is a Fintech startup providing a payment solution for merchants, quick to integrate and easy to use. They are looking for Android/Kotlin developers: Start: February Duration: 6 months Location: Remote Requirements: strong knowledge of Android and good knowledge of Kotlin, strong knowledge of Gradle Nice-to-haves: experience with iOS development and tools (should not be afraid to write some iOS code), with CMake and CLion Team: 1 team lead PLEASE MESSAGE ME DIRECTLY 👍

While this works perfectly fine:

fun bar(x: Int): Int = when (x) {
    0 -> {
        listOf(1).forEach { return 0 }
        error("never")
    }
    else -> 10
}

from inside a foreach? isn’t that returning from the lambda you’re passing to foreach

Does anyone know how I can let my Spring controller return a 404? I thought I could just return a nullable variable and if it is null Spring would translate it to a 404. Do I really need to use

ResponseEntity

specifically?

Is there a way to generate Kotlin from protobufs?

I’m not sure it’s that much better than

if

but it definitely beats Smalltalk’s

ifTrue

and

ifFalse

Looking at the bytecode, using

_

inside a lambda does not change the fact that the compiler will automatically assign a value to

it

<application android:name = "com.example.DemoApp" ... (edited) And I have created DemoApp in kotlin like this class DemoApp:MultiDexApplication() { ... }

Hey. I have an question. (Simplified problem -->)

class A(val name: String, val country: String)
class B(val name: String, val age: Int)
class C(val name: String, val age: Int, val country: String)

What is the idiomatic way in Kotlin to combine two lists say

List<A>

and

List<B>

to a new

List<C>

if

C

is produced from

A and B

if

a.name == b.name

?

How to use a generic with a constructor inside a class ?

I don’t get this factory method stuff :(

Put everything in a single

apply

?

Does anyone know where to find documentation on how to write a Kotlin compiler plugin? Or at least some general information about the architecture of those plugins. I am currently using JSON-B (Yasson impl) in my project but it can only instantiate a data class when I annotate the constructor and all parameters (providing the parameter name). As a fallback I could of course use the noarg compiler plugin but I was wondering if annotating constructor parameters using a compiler plugin is possible.

#general is not for self-promotion

map {}

can't be short-circuited like a forloop can right?

it all looks the same in the end
