Great. Thanks so much!!

This one right, @Adrian M ?

exactly

Did I miss any kotlin extensions for handling java's Path objects? I am trying to copy out some files from a jar file programmatically, but find I have to use java libs, since I only know kotlin extensions for File objects ...

I prefer the first one since it is abundantly clear that the map is just the Foo call and nothing elsez the latter can be a bit confusing of there are multiple `it`s in scope.

Is there any tool available for checking the correctness of syntax in Android Studio? Something like using eslint for react native applications

ktlint

how about detekt

detekt is easier to integrate i guess if you know how to write the rules properly in the yml files

as that sentence goes on your appear to contradict yourself

yes a sort of

😂

but i still beleive configuring it a bit easy

sample of ktlint https://github.com/JLLeitschuh/ktlint-gradle/tree/master/samples

guys is there any way to do this:

class ViewState(
            val selectorMinValue: Int,
            val selectorMaxValue: Int,
            val selectorSelectedValue: Int,
            val startTimeMinutes: Int,
            val endTimeMinutes: Int,
            private val daySelection_: BooleanArray
        ){
            val daySelection: BooleanArray
                get() = this.daySelection_.copyOf()
        }

in the constructor?

i mean, a getter that returns a copy

nvm i’ll just use a list. an array is not really mutable

immutable*

is there a way to know when the function writeText (https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.io/java.io.-file/write-text.html) has finished writing ? i can't find any clue on how to do it

What's the use of

final

keyword?

@mg6maciej https://kotlinlang.org/docs/reference/classes.html#overriding-methods

To limit overriding in an open class.

if I have a base class and child classes, and I add extensions with the same name to the classes, and call the extension on an object of the base class, it doesn't call the extensions on the child classes like override methods. Is there a way to accomplish that other than using methods rather than extensions?

No, extension functions are statically resolved, and you can't override static function.

Why would you want to create a secondary constructor with optional parameter that just delegates to primary constructor with the same non-optional parameter? Case in point: https://github.com/Jetbrains/kotlin/commit/8d5e69b06cb9e6a33f4d65a099d02d6a96b35c61#diff-6f01e20fe41ed86ccfc251b5bb7d2f74R52

class KotlinInlineValHandler(private val withPrompt: Boolean) : InlineActionHandler() {

    constructor(): this(withPrompt = true)

Backwards compatibility, interop, there's a few reasons.

does putting a default argument in the primary constructor generate the second automatically?

generate as in, will there be 2 constructors in the bytecode? No, you need

@JvmOverloads

for that
