what is the most efficient way to round

Double

up to certain decimal points, there is

round()

function in Kotlin but it always completely rounds up to 0 decimals? I want something like

round(1.4999,decimalPrecision = 2) // 1.50

Is there a way to simulate activity's

back pressed

state for compose-navigation?

popBackStack

does not finish navigation (and instead just removes the destination) but pressing the back key always works perfectly. This becomes a problem when you have nested navigation as the inner navigation stacks can never pop themselves

(I know it's more a Jackson than a Kotlin question, but I hope someone might have an answer anyway). I have a line `val jackson: YAMLMapper = YAMLMapper.builder().addModule(KotlinModule()).build()`in my code to create a Jackson YAML mapper with Kotlin extensions. This tells me "Kotlin: 'constructor KotlinModule(Int = ..., Boolean = ..., Boolean = ..., Boolean = ..., SingletonSupport = ..., Boolean = ...)' is deprecated. Use KotlinModule.Builder instead of named constructor parameters". Does that really mean I should use `val jackson: YAMLMapper = YAMLMapper.builder().addModule(KotlinModule.Builder().build()).build()`instead? That's an awful amount of build...

Is there a way to disable webpack's auto reloading?? It really doesn't help while doing compose 4 Web at all. I am trying to see if disabling it might give me more iteration speed

Trying out Kotlin 2.0.0-RC1 and getting

I'm trying to map enum to int values:

@Serializable
enum class ItemType {
    @SerialName("0") Zero,
    @SerialName("1") First,
}

But it fails with the following exception:

JsonDecodingException: Unexpected JSON token at offset 194: Expected quotation mark '"', but had '1' instead
    JSON input: ....."type":1,.....

It doesn't seem to work because

SerialName

is expecting a string and json has an int. I can think of two ways to solve this: 1. Enabling lenient mode - I don't like this solution as it also removes restrictions from other fields, which I prefer to keep 2. Implementing a custom serializer - seems like too much of boilerplate code for such a simple task Am I missing something?

I'm trying to configure a ktor application using the configuration file, as described here: https://ktor.io/docs/configurations.html#configuration-file ... I've put a file on my

src/main/resources/application.conf

and works great. However, to deploy the app I create a fat jar. Is there a way to override some configuration options when I deploy that fat jar ? I know that I can use env vars but there are too many options that would need overriding. is it possible to pass another configuration file to the fatjar that would be used to override configuration options ? i.e run it like

java -jar ktor-fat.jar -c local.conf

; when trying to read a configuration value, it will first check

local.conf

, if not found then go to

resources/application.conf

inside the jar
