Is there a way of not exposing the concrete type without having a private backing field? For example having an ArrayList but exposing only the list.

Hey folks, Using simple paginated call:

fun loadPage(offset: Int, limit: Int): List<Int> {
    println("Called for offset $offset and limit $limit")
    if (offset == 300) {
        return listOf(offset + 10) // return 310 - last element
    }
    return (offset..offset + limit).take(limit)
}

fun paginatedCall() {
    val limit = 100
    var hasMore = true
    val total = generateSequence(0) { if (hasMore) it + limit else null }
        .map { loadPage(it, limit) }
        .fold(0) { c, list ->
            hasMore = list.size >= limit
            println("Consumed list of size ${list.size}")
            c + list.size
        }
    println("Total - $total")
}

paginatedCall()

Was wondering if there's any better way to implement

paginatedCall

(assume

loadPage

fetches records from DB)

Is there any native functionality yet for formatting double while using string templates? Or is the best way still is to use the following or make an extension function for same

".2f".format()

I saw kotlin's internal error. Is there a way to avoid it? https://gist.github.com/tateisu/ed1dbbca0e85e0173760c375776bed87

@william you can wrap it in an

ImmutableList

. That means that no matter what the underlying object is, it cannot be changed.

That said, users should respect the API, and if they decide to manually downcast they are kinda on their own, so I wouldn't worry about it.

https://twitter.com/kotlin/status/1321047218636443648 The Kotlin standard library is required in almost all projects. From Kotlin 1.4 onwards it is added by default in each source set, so you no longer need to declare a dependency on stdlib in any Kotlin Gradle project, including multiplatform projects. #KotlinTips #KMM https://t.co/VsPyd3chnY Twitter

Namaste Devs, Thanks for inviting me

I’m rolling my own library for process execution (captures stdout & err, that sort of thing) but it occurs to me I’m probably reinventing the wheel - is there a nice kotlin lib for that sort of thing around already?

I was trying out Kotlin scripting in IntelliJ. Whenever I add external dependency I see message "Applying Context" in IDE. What is it actually doing? Just trying to figure out if I were not to use IDE and I add maven dependency to say Retrofit do I need to update any file? I have multiple script files that I am referencing from main script file.
