are coroutines going to be merged into the standard library (kotlin-stdlib) for the 1.3 release, or will they remain a separate artifact?

support for coroutines in the Kotlin language is part of stdlib.

kotlinx.coroutines

library will remain a separate artifact and will be released in a stable version

1.0.0

together with Kotlin

1.3.0

.

Yeah, that's what I meant. Thanks!

@elizarov sorry this may seem silly but what exactly do you mean by that?

Exactly what I’ve said. What part of that need clarification? Can you elaborate your question, please?

@tw The Kotlin standard library has support for, but no implementation of, coroutines. The implementation is provided by the

kotlinx.coroutines

libraries. My question was, will the implementation be merged into the standard library? And the answer is, according to @elizarov, that the implementation of coroutines will stay outside of the standard library. Does that answer your question?

To be fair,

sequence { ... }

coroutine builder is a part of stdlib. You can write and use suspending functions anywhere — that is fully supported by Kotlin (the language) and its standard library. You can start new coroutines via

startCoroutine

using just stdlib.

AHH this makes sense

I do have one more question @elizarov: is there any particular reason why

runBlocking

isn't in

coroutines-core-common

?

Yes. It cannot be implemented in JS.

Gotcha, thanks. 👍

You cannot block JS event thread.
