In a Kotlin multi-platform (or JS) project, (how) can one pass custom command line arguments to Node.js? I'm working on a Kotlin multi-platform project, and I need my JS tests to run on Node.js but with custom command line arguments (specifically I need node to run with the --expose-gc flag, because some tests need to trigger garbage collection). Looking at the documentation for the Gradle Kotlin JS DSL I didn't find any mention of how to do that; does anyone know whether it's at all possible and how?

Using ReactApplication in Junit4 tests? I'm writing a test for a method that takes a Context as an argument and casts it internally to ReactApplication. I first wanted to handle this with mocks - but if I pass in a mock Context then it can't cast internally to ReactApplication, and I can't pass a mock ReactApplication as it needs to receive a Context as an argument. What is a good method to handle this taking into account that I can't modify the method signature?

How can I change how Ktor encodes spaces in query parameters? By default, Ktor encodes spaces as + in query parameters, which I understand is the general convention. However, the API I have to work with is not particularly well-designed, and so it only accepts %20 as a space, even in query parameters. Is there any way I can tell Ktor to always encode spaces as %20 no matter the context?

Is there a better way than a RecyclerView? Currently everything is working except for the show/hide of the TextViews. My code:...

How to perform operations in case of negative numbers? I wanted to build a calculator app for android and for that I needed a parser to convert string expressions to be solved. Now Java and Kotlin doesn't support eval function and importing a javascript engine just for sake of an operation can open me up to various vulnerabilities. So I made my own calculator parser. Now it's working completely fine, all arithmetic operations are working fine except in negative numbers in crash. I do know what the problem is as I am splitting the string using...

Arrow.kt loading state I used arrow.kt library so many times, I really enjoyed the features they gave to extend kotlin. I like how Either can represent the success/failed states seamlessly. I am just wondering if arrow.kt has a way to represent loading state along with the other two. In other word, we will have a type that offers three states: Success, Failure, Loading. I tried to use Option as right member, but None can't represent loading state as required. Is there any thing I can try?
