seems they deprecated a lot in 1.3

>>Deprecation cycle:

<1.2: assigning one value element to vararg in named form compiles fine and is treated as assigning single element to array, causing non-obvious behavior when assigning array to vararg 1.2.X: deprecation warnings are reported on such assignments, users are suggested to switch to consecutive spread and array construction. 1.3.X: warnings are elevated to errors >= 1.4: change semantic of assigning single element to vararg, making assignment of array equivalent to the assignment of a spread of an array

Hi. I’m trying to write library in Kotlin. When I start my Java app with this library I get few warnings. I’m from mobile app so can’t provide you real error but I see the same warnings in this unanswered question https://discuss.kotlinlang.org/t/cannot-find-kotlin-metadata/8531

is there a visibility modifier that would allow visibility only in one file?

private

(but it has to be top level)

i see.. thanks

Hi all

New Language Features Preview in Kotlin 1.4.30 We’re planning to add new language features in Kotlin 1.5, and you can already try them out in Kotlin 1.4.30: Stabilization of inline value classes Experimental support for JVM records Experimental support for sealed interfaces and other improvements for sealed classes To try these new features, you need to specify the 1.5 language version. The […]

I didn't realise you can get rebuilt stacktraces from coroutines, that's great: https://github.com/Kotlin/kotlinx.coroutines/blob/master/docs/debugging.md I assume becuase this is debug only there must be some performance impact - is it large, does anyone know?

I was here already many times, but not enough to convince that it will not possible

fun selectServiceNoThanksListItem() = adapterDelegateViewBinding<
    SelectService.ListItem.NoThanks, 
    SelectService.ListItem,
    ItemNoThanksBinding>(
  viewBinding = { inflater, root -> ItemNoThanksBinding.inflate(inflater, root, false) }, ....

We have static function inflate that sits in the scope of the generated class. The class is generic parameter for this function. Would it be ever mechanism to not write this view binding lambda all the time just because we don’t have class information in runtime? Do you have own solution for this problem?

Hmm, github linguist still didn't gave any colors/highlights to kotlin annotations 🤔, though they are given scopes by the grammar https://github.com/github/linguist/issues/5085#issuecomment-724118549 What do y'all think, should they be colored? If yes which color should be the best? Does the same color as keyword looks good or something else, like orange or something blob thinking upside down.

Can I check the technology used to build an app? Native Java/Kotlin, Flutter, React Native? Kind of Wappalyzer's working on web. Manual checking or by tool is ok.

Hey folks! Hope you enjoy new JVM compiler. If not, please try it)

Hello everyone, what's your personal favourite DSL in Kotlin that replaced a Java DSL? So for example I for myself really like the KotlinDSL for Springs MockMvc which looks way cleaner than the java one imo. What comes to your mind? (I'm looking around for examples that I might have forgotten)

https://twitter.com/kotlin/status/1359533856634916866 Use “Change Signature” refactoring to swap parameters. It automatically swaps the corresponding arguments for all the usages. Swapping parameters manually is too prone to error. #KotlinTips https://t.co/0aaS1qcdXv Twitter
