do you know any async-await implementation for M04 that works on JVM with java1.7?

@pawel_byszewski https://github.com/mplatvoet/kovenant/blob/0fac17d84811566fbadc478c36d7922e69a359ce/projects/core/src/main/kotlin/coroutines-api.kt

thanks

@adambl4 as I see there is new thread for every

await

operation and new thread for

continue

part. Let’s consider some code

println(“one”)
    async {
        await(longOperation())  // longOperation prints “two” 
        println(“three")
    }

every string is printed on another thread. For me it is unintuitive. I have faced up the problem to print “three” on the same thread as “one” thats why I am looking for some async-await implementation

@elizarov ^^

@pawel_byszewski The whole point of coroutines is to disengage your computation from threads. In the code above

await(…)

is a suspending function defined in Kovenant library. When you invoke a suspending function your computation gets suspended and the thread it was running on is free to do any other stuff. The implementation of a particular suspending function decides on how and when your computation is resumed. This particular library (Kovenant) is multi-threaded (it has multiple threads to resume your code). If you are looking for Node.JS style execution where everything works in the same thread, you’ll have to write (or find) a library that schedules everything into the single thread. Kotlin standard library provides all the necessary building blocks, so that writing such single-threaded coroutine library is straighforward.

The coroutines design document provides the corresponding example: https://github.com/Kotlin/kotlin-coroutines/blob/master/kotlin-coroutines-informal.md#cooperative-single-thread-multitasking

@pawel_byszewski Why do you need to print "three" on the same thread as "one"? Is it related somehow to updating UI or other thread-affine tasks?

btw, there's a #coroutines channel, feel free to join to discuss coroutine-related topics.

to clarify situation. I want to get a deep knowledge about coroutines thats why after reading all the docs, I have started with own implementation , based on single threads, custom thread pool, even rxjava:) I have thought that sometimes it could be useful and more readable to have all not-suspendable operations on the same thread. To run Continuation part on UI thread depend on system that we are developing for. So I was thinking about some more general solution

ok, I will move to coroutines channel

Hey guys. Is data classes inheritance in 1.1 M04 already?

Yes, you can inherit data class from any open/abstract/sealed class

I see, thanks. Any plans already for a release date? I have some legacy Java code that uses inheritance in models that I’m refactoring to Kotlin

@udalov pinned a message to this channel.

anyone seen a situation where the plugin keeps reporting

This feature is only available since Kotlin 1.1

even though the project is configured for 1.1-M04? actually, every error shows up three times 😕

i've already tried adding and removing the plugin, downgrading + upgrading, deleting

.idea

... nothing seems to get rid of it

@damian Invalidate cache and restart?

@cedric no luck 😞

@User uploaded a file: and commented: @damian Check in the project structure whether Kotlin versions of the module are set to 1.1

It is an Android studio project. Those options don't exist here, I don't think? It's all configured in gradle (and builds fine)

@User uploaded a file:

@ilya.gorbunov commented on @ilya.gorbunov’s file : Ok, could you add Kotlin settings facet then?

@damian for me only solution was to clone and import project again

@ilya.gorbunov Are you sure this option exists in Android Studio? I've not seen anything like that in the module settings

No, I'm not sure, what items do you have in that menu?

@User uploaded a file: and commented: I don't think it even exists in AS... There is only the module settings window (cannot right click any modules here... the

+

button is only for creating new modules)

@pawegio not really an option since I have local work in this repo. I've deleted

.idea

though, which should have a similar effect

@User uploaded a file: and commented: there is this screen, but it is already set to 1.1
