https://twitter.com/kotlin/status/1270287040828096513 The 'joinToString' extension function provides a rich set of options for transforming iterables into strings: Separators, prefix and postfix, limiting, and even the possibility to specify a lambda for transforming individual objects to their text representation! #KotlinTips https://t.co/mru0gHXvLg Twitter

Hi all, can anyone help point me in right direction here? I am just trying to store a set of function references.

use koin

i never do @Inject within my implementations

on init?

Gurovich?

It seems like compile randomly fails on IntelliJ latest build with Kotlin 1.3.7 and latest kotlin plugin when using inner classes like so:

open class A(){
  var b: B ?= null
  inner class B(){
    var t = 1
  }
}

class AA(): A() {}

// using from different class
...
AA().apply {
  b = B().apply{ // this causes random compile errors after changes unless we change it to explicit "b = this.B().apply ..."
    t = 2
  }
}
...

I'm gonna guess it will prolly never get fixed due to how trivial it is ¯\_(ツ)_/¯ Note: "randomly" literally means randomly where after compile error of "Unresolved reference", you just have to delete /target and build again

👋 I’m here! What’d I miss?

Is there a comparison on the paradigms (similarities and differences) used by Java, Kotlin and Rustlang?

Does anyone know where gradle sourceSets view (with dependency listing) gone in new intellij version?

compiler says no cast needed but breaks without it

This bite me today… https://pl.kotl.in/8VE-crdSw

is there a way to set a variable depending on the input, i.e.:

val aFlags = (1, 2)
val bFlags = (2, 3)
val cFlags = (3, 4)
val dFlags = (4, 5)

fun processInput(letter: Char) {
  return letterFlags
}

The use case is I have a lot of different data I need to process, and the flags to compare it depend on the value the user is passing in. For instance the user would call:

processInput('a', their data)

Then my function would grab the list of flags using the variable name

aFlags

and process their data that way. I know I could use a when statement, for instance, to do it, but I was just wondering if kotlin had a way to get member references that way

I am thinking that doing it this way, I wouldn't have to keep expanding a when statement

you canstore lambdas in a dictionary

if I mark

getValue(ref, kProperty) : T

anything other than

T?

, i get a compile error when I try to return a null-something inside

getValue

Hi All I have recently put a poll out on Linkedin about technical tests during an interview process. It would be great to hear all your opinions on them.

Why is the same declaration creating two different types, depending on the place I put it: https://pl.kotl.in/7HL-NQFDT

is it scope related?

that’s a weird one

It's in fact a documented behavior https://kotlinlang.org/docs/reference/object-declarations.html#object-expressions

https://twitter.com/kotlin/status/1273527318686904322 We’ve updated the IDE plugins in 1.3.72 with some important bug fixes. See the full list of updates in the changelog: https://t.co/yITqwYaDGA Twitter

Where to download Kotlin

1.3.61

? I'm trying to find it in the Github's releases tab but there seems to a nearly infinite number of builds and the page isn't updated if I enter the version in the URL. Edit: Found it: https://github.com/JetBrains/kotlin/releases/tag/v1.3.61

actually I need the runtime and this has only the compiler. To run

javah -jni -cp ".;path/to/kotlin-runtime.jar" sam.NativeSample

, like described here: https://github.com/fuzzdota/kotlin-jni-example

Hello, my team is evaluating to use Kotlin Multiplatform for our Android and iOS apps. One concern I have is in regards the ability to link against multiple Kotlin Multiplatform libraries in the future. I saw there is a limitation on iOS specifically looks like: https://github.com/JetBrains/kotlin-native/issues/2423 it appears that it may have been fixed on a more recent version of Kotlin 1.3.70, could anyone please confirm?

except doing something like

list.filter {...}

and then checking again the first list against the filtered elements.
