Actually arm64 is a target in Kotlin-native right now

Hi guys. I just tried to use

1.1.3

and got following error

e: /Users/erakitin/Projects/android/wakiex/domain/build/tmp/kapt3/stubs/debug/com/wakie/wakiex/domain/model/users/profile/ProfileSettings.java:95: error: ')' expected

It looks like there is an issue with naming in

kapt

1.1.2-5

works fine.

is there a function on collections that somehow mapsIndexed and filters at the same time? I need the indices of objects that have a specific property. I can't filter first because that would change the indices and I cant map first because then I lose the objects. Of course I could zip the objects with their original indices and then filter but I'd like to avoid that as kotlin doesn't have nice tuple syntax.

1.1.3 is nice, compile time with JRebel reduced from 10 seconds to around 3.5 seconds which is a huge improvement!

Couldn't find an android dancing with kotlin flags

Is there a way to define a c’tor which will look like this one instantiating (not specific use case, just playing with the language): var myclass = MyClass { propertyA = “Val1” propertyB = “val2" … }

I'm trying to upload a maven jar etc. to bintray. However, the sources jar is uploaded twice (which makes the build fail) this is my build xml: https://gist.github.com/anonymous/5bf0e30435389897e48e075b5c9a648a

I'm trying to run kotlin-fullstack-example https://github.com/Kotlin/kotlin-fullstack-sample I clone git repo and run

gradle :frontend:run

Then get following error:

> Task :frontend:npm-install
npm ERR! code ETARGET
npm ERR! notarget No matching version found for kotlin@1.1.1
npm ERR! notarget In most cases you or one of your dependencies are requesting
npm ERR! notarget a package version that doesn't exist.
npm ERR! notarget

Anybody managed to get it running?

Your function needs a generic parameter

<T>

, so

fun <T> List<T>.moodi ...

&

becomes

and

,

|

becomes

or

and

<<

becomes

shl

. Bit manipulation is highly suboptimal in Kotlin at the moment, sadly.

It does not work @diesieben07

This has been known for probably at least a year and nobody thinks it's worth addressing? Makes me wonder what else I'm going to run into with Kotlin. Maybe a compiler warning would be a good start: "Calling valid code from here can easily result in null pointer exceptions where they are ordinarily impossible" ... this feels like undefined behavior.

Hello everyone. Who knows more information about the word Kotlin. I know that is island name, but why the name of island is Kotlin?

hello, so i was trying to find a more elegant way to write the following:

selectedChoices.mapIndexed { index, isSelected -> if (isSelected) index else -1 }.filter { it != -1 }

. Is there a prettier way to write this ? 🙂 In short what I want to do is get the indexes from

selectedChoices

, which is a BooleanArray, where the value is

true

and then map those indexes in something different, hence the

.filter { it != -1}

(also not sure if I am on the right channel)

@pavlospt

selectedChoices.foldIndexed(mutableListOf<Int>()) { index, acc, bool ->
        if(bool) {
            acc.add(index)
            acc
        }
        else acc
    }

Can be ?

Is there any shorthand for

if (condition) a else b

?

hi all-- is anyone here using a static analysis tool for security vulnerabilities with Kotlin? currently shopping around… the security team here is against analyzing java bytecode, and they’re not going to budge 😕

How do I write custom setters for a class variables where the class is data class ?

@oblakr24 You may check generated bytecode from IDE (and then convert it to Java for easy reading).

@maciekjanusz to tell you the truth I had no use for it until I started programming in Kotlin JS, there I came across a few situations where it could be useful - usually in an if else type scenario. if "success" call with all parameters, if failure call with null on a parameter... (because you can't really pass anything else to the parameter since the value is not available due to failure. Why useful for me in JS? because in JS I have a lot of callback type situations. My way of thinking is that functions have parameters, but function types also have parameters - so why not? but I imagine it's not required most of the time by most people.

hi, anyone here tried to use kotlin with hibernate and jackson? (also spring, but i dont think this is important here) after adding kotlin-noarg and kotlin-jpa to my project I got

com.fasterxml.jackson.databind.JsonMappingException: Could not find creator property with name zxc

errors for entities that works without this plugin

so i'm having trouble with lazy delegated properties in deserialized classes

If you're gonna add something, don't go halfway 🙄

What would cause the kotlin bytecode decompiler not work? I got error message

Failed to decompile X.kt. Method Y couldn't be written

If I only want to modify a nested field of a data class, using

copy()

, what’s the cleanest way to write it? this obviously does not work:

val widget = widget.copy(owner = this.copy(firstName = "alfred"))

No, you cannot. Think of extension functions as syntax sugar for "static methods".
