@antonkom It’s known bug - https://youtrack.jetbrains.com/issue/KT-15459

@gildor ty

How hard would it be to hack the Kotlin compiler to print out the source locations of everywhere a local variable box is generated?

We are debating whether we've got some code in our codebase that relies on variable boxes being volatile. We think the answer is no, but aren't quite sure. If it's a quick hack one of us could throw together a patch and do an audit

I don’t think I know a quick hack to accomplish that. The only bulletproof way I see is to wrap the ASM visitors that the back-end is using and detect references to

kotlin/jvm/internal/Ref$…

. You can look for

CoroutineTransformerClassBuilderFactory

for an example

also you can start with just

grep kotlin/jvm/internal/Ref

on your binaries, maybe there’s just not a lot of variable refs at all

yeah, good thinking. can just grep the binaries.

Hi, I have being looking at some awesome kotlin libraries/frameworks on github… but I am kinda confused... it looks like many projects just don`t have documentation… just some readme samples or sample projects in the same repo… I feel bad about comparing projects… but when you want to start to learn something new and compare the kotlin project support with projects in swift/node or even php projects on github they seem to have better documentation (which is not hard due to the current state) and easier to start learning/using.

a lot of kotlin users just use java libraries.

so many kotlin "libraries" are either just thin extensions on a java library, or just people playing around

not the case...

When debugging I can’t see variables anymore. I get this error:

Debug info might be corrupt: Unexpected JDWP Error: 101

which libraries were you looking at?

When I try to update the Kotlin plugin to 1.1 beta I get "Plugin update not installed" notification in the lower right corner...

@roman_gemini works only for

val

var could be changed after null check from another thread

try

field?.let{ doSmthWith(it)}

thanks

ok somehow the kotlin plugin `1.1.0-beta-Studio2.2-1' compiles

open class MyCookie()
data class MyBrowny(val color: Int) : MyCookie()

however android studio still shows an error regarding data classes inheritance being forbidden, do i need a specific android studio version? (using 2.2.3 currently)

i have checked, the language is set to 1.1 in the kotlin compiler settings

same here

funny that the last post here was exactly what I was looking for 😄

I can check for 2.3 beta2 if someone will tell me how I can migrate from 1.0.6 😉

@jan.rabe I was having this problem yesterday... for some reason the plugin wasn't updating the project correctly. Check your project's

.iml

file for the

<KotlinVersionInfo>

section -- you may need to set

apiLevel

and

languageLevel

to

1.1

manually

that fixed it @damian thanks

"extension lambdas in SAM conversions" does this mean we can write SAM interface in Kotlin and pass lambda where that interface is required?

I know I can do:

val (id, code, name) = "11;33;44".split(";")

but can I auto create some data class similarly? Like

data class Country(val id: String, val code: String, val name: String)

val country: Country = "11;33;44".split(";")

I mean I tried and it doesn't work, maybe I miss some feature? 🙂

would be so cool to have destructuring work like this 🙂

Nope, it doesn’t work like this.

ok but you would not know at compile time if it works
