android-studio - 如何在kotlin coroutine中显示 “@coroutine#2” ,“@coroutine#3” ,“@coroutine#1”？

Question

import kotlinx.coroutines.*

fun log(msg: String) = println("[${Thread.currentThread().name}] $msg")

fun main() = runBlocking<Unit> {
    val a = async {
        log("I'm computing a piece of the answer")
        6
    }
    val b = async {
        log("I'm computing another piece of the answer")
        7
    }
    log("The answer is ${a.await() * b.await()}")    
}

Kotlin 的文件

[main @coroutine#2] I'm computing a piece of the answer [main@coroutine#3] I'm computing another piece of the answer [main@coroutine#1] The answer is 42

我的Intellij IDEA和Android IDE

[main] I'm computing a piece of the answer [main] I'm computinganother piece of the answer [main] The answer is 42

如何显示“@ coroutine＃2”，“@ coroutine＃3”，“@ coroutine＃1”？

Answer 1

打开运行/调试配置窗口，然后将-Dkotlinx.coroutines.debug添加到 VM选项中:

完成之后，您将获得以下输出:

[main @coroutine#2] I'm computing a piece of the answer
[main @coroutine#3] I'm computing another piece of the answer
[main @coroutine#1] : The answer is 42
