kotlinlang

i’m trying to use this library to extract a tar file <https://github.com/kamranzafar/jtar>
but i’m having trouble converting the example to kotlin since assignment doesn’t work in while conditions. how can i accomplish the same thing in kotlin, or does anyone have a suggestion for a kotlin-first library for this task?

Well I think you _could_ assign using `also`
Eg `while(origin.read(data).also{ count = it } != -1)`

use this idiom:

object Tis{
    fun read(): Int = Random.nextInt(-1, 10)
}

fun main() {
    while(true){
        val count = Tis.read().takeIf { it != -1 } ?: break
        println("count: $count")
    }
    println("ready")
}

you can also do `read().also { count = it } != -1` in case its more readable than restructuring the code
