sorry for the stupid noob question but i can't find any answer when running kotlin scripts via

kotlinc --script

how do you include/import/whatever another file like if i want to have a

common.kts

If it's really just for simple tests can't you use

assert(a == b) { "a wasn't equal to b" }

from the stdlib?

FYI if anyone else comes asking about kscript, this has either answered or lead me on the right track to answers for most of my questions: https://resources.jetbrains.com/storage/products/kotlinconf2017/slides/kscript.pdf

I tried to use

(0 until list.size - 1). filter{ list[it] == list[it + 1] }

but it doesn't work for case

333

->

33

Do I not undestand smthng?

does kotlin have a postfix if? eg.

doThing() if true

I invalidated my caches and restarted, still the same.

hm! I didn’t know you could do the array literal

[ ]

instead of

arrayOf

anyone familiar with the Strategy pattern?

and I wanted to see if this is the best way to do such a thing, or does Kotlin facilitate the purpose of this pattern more easily

Is Kotlin easy to learn then Java?

listOf(
    "is",
    "sec",
    "changeset",
    "reg",
    "fileuploads"
    /*
    "pdf",
    "user-authn"*/
).forEach { if (file("lib/" + it).exists()) includeBuild("lib/" + it) }

I want to rewrite this to simply list lib, and then do the needful

Based on the question above, I wonder if soon people will learn Kotlin instead of java . I have a friend that works in construction and was thinking what was the best to teach him, since the Kotlin tutorials usually compare the code to java

Hi, I have a question regarding Kotlin Koans: Collections: Max min - I'm trying this solution:

fun Customer.getMostExpensiveOrderedProduct(): Product? = orderedProducts.maxBy { it.price }

but it's failing and I'm not sure why. The test error is

Expected: null
Actual: null

, so that's not really helpful to find out the problem

As of now that's the correct way to do it. The team has noted they're planning on adding it, but it's been on the table since 2014 so we'll see 🙂

I'm not sure if creating Handler object is best way to do that

Hi All, is there any way to create a class that implements the same interface multiple times with two generic parameters, where one parameter is a subclass of the other? i.e.

interface A
interface MutableA : A

interface Container<out E> : List<E>
interface MutableContainer<out MUTABLE : READ, out READ> : Container<READ>, MutableList<MUTABLE>

@RandomBK What are you trying to acomplish? How would usage of this class look?

is there anyone coming to Kotlin from Clojure? 😮

We switched to Intellij. 😉

Hi all. I'm new to Kotlin, coming from the javascript world. I've primarily only worked with javascript, node, react, etc. and while I feel I've got a pretty decent grasp of all of that, I'm in a job now where I need to use Kotlin. Most of the learning resources I've found have been from the perspective of java programmers or android programmers. Does anyone have any resources that aren't written from that perspective? Also, are there any resources written for folks coming from javascript?

no such way available. I’m setting textView.text = “” but unable to do so for TextColor

You should still be able to just call the setter exactly like you would in Java.

for ((index, entry) in map.entries.withIndex()) { ... }

would work if you really need it.

@chb0kotlin

interface Populace {
   val people: Set<People>
}

Hi everyone, have decided to learn Kotlin but im unable to see a tangible pdf online that talk about kotlin without using it for Android, who has a good pdf (like head first kotlin) to start with or link to online resources that that teaches normal programming in kotlin. Regards

As I remember

.()

lambda with receiver

Hello all!! I have one question about TDD on Kotlin, in my case, in java, my stack to do TDD is jUnit + Mockito, and Rest-assured when have to test Rest services. In case of kotlin, is a good aproach this stack or are better other test framework?

@Max Russek would you mind providing a code sample?
