set the channel description: Kotlin By Example Contributions

I like the idea 👍

nice, I’ll try to contribute with some of piece of code

Thank! I’ll try and add placeholders for examples we need

Great idea 👍

One thing that's not clear is which GitHub repo should be used by contributors? I only see the link to mark-code itself.

put in a pull-request for loops (for, while, and do while)

@oleksandr.samsonov has left the channel

I’d taken a few days off, so running behind on the PR’s. Hope to get to them tomorrow and day after

@arocnies has left the channel

So I’m going to make some changes to the site.

I want to bring in executable code blocks so people can test the code right there and then. This might require some changes to how we write things. I’ll port all the existing contributions and set up guidelines moving forward.

It’s a bit of work, but I think it will be better to allow people to play with the code directly there without having to fire up an IDE.

If any objections, concerns, or thoughts, feel free to comment 🙂

hi guys, just i'm a beginner to kotlin progra, any one can explain what is the difference between abstract and interface in kotlin?

set the channel topic: Discussions around the site kotlinbyexample.org

Hi all, I can't see executable code blocks when accessing kotlinbyexample.org ? Have they been removed or is that a browser issue?

Trying to run the kotlin-koans https://kotlinlang.org/docs/tutorials/koans.html, I cloned the repo, imported as a gradle wrapper task, and tried to run the first koa n00Start.kt using the Run menu in IntelliJ CE 2017.2.1. Gradle builds it, but doesn't run it. I expected to see some kind of JUnit window, but I just get "BUILD SUCCESSFUL" from Gradle. I don't know Gradle at all; is further config necessary to get the koans to run?

class ChildValidation<T> {
    var validations: MutableList<Pair<T.() -> Boolean, String>> = mutableListOf()

    fun be(validate: T.() -> Boolean) = validate

    infix fun (T.() -> Boolean).message(error: String) {
        validations.add(this to error)
    }
}

Hey guys ,I am trying to understand library code written in Kotlin, I am not getting the syntax

T.()

What is this representing ? I know,

() -> Unit

is used to represent a function .but this is

T.() -> Boolean

different . Any help is appreciated

What is class
