I would use Guice, I feel it is simpler to configure. Dagger is more performant, but requires code generation AFAIK.

I agree that building the DI graphs in cumbersome and the boilerplate to integrate them is verbose, but I do find them useful when writing unit tests. Instead of rewriting your project in test form, you just swap dependencies with mock ones and don't really think about it.

yes, I am.. and so what? why should a user that needs more than 1 kotlin library be greeted with this message and no suggestion for a fix?

it looks like Kotlin has all except the Form Feed, http://www.javacodex.com/Basic-Java-Examples/Java-Escape-Sequences

I know this question maybe already questioned before but looking for answer from experienced developers, can we share business logic between iOS and Android using Kotlin Native or it will bring more trouble than helping saving time?

this time with a “Maintenance is in progress…” message and a throbber to go along with it

there’s this bundle of O’Reilly books on Java at Humble Bundle this week: https://www.humblebundle.com/books/java-books are there any of those you’d particularly recommend to those of us coming to Kotlin without a Java background?

No joking, someone in Lynda.com has a Kotlin course. It covers funKTionale... I saw the video trailer and the guy is just reading the Wiki 🧌

Hi, I have a question about the idiomatic usage of maps. I have a map and want to retrieve a value. Before doing so I call containsKey. Afterwards I call get:

val planetHasNumberOfSettlers = mutableMapOf<Number, Number>()
val nrOfSettlers: Number = if (planetHasNumberOfSettlers.containsKey(closePlanet.id)) {
                    planetHasNumberOfSettlers[closePlanet.id]
                } else 0

Now the compiler emits an error: Type mismatch Required Number Found Number? I get why that is, but shouldnt kotlin be able to infer that I make sure that the item is existent?

That happens all inside one function, the map is created there and destroyed

Is there any reason you can't link to a specific function using kotlin documentation...

thank you, I give up, I’ll use a

(Foo)->Unit

instead 😁

wouldn’t it be nice to also have a copy method for deep copies?

Kotlin 1.1.61 is coming!

Hello everyone, how can I create a data structure for example with two different types like ArrayList<Double, String>

@karelpeeters Missed opportunity there, should have been called "bang bang"

how do I check if a map contains a certain entry?

that is my first time ask iam civil Engineer work with Excel sheets with macro is that possible to use kotlin with Excel without visual basic🙂

@Shawn yeah you're right it just bugs me that I try to be objective about new languages and they just flat out dismiss them because it's not C++ or it doesn't have new features that benefit them or something. But I've read a post by the CEO of JetBrains that making kotlin go native is a bad idea and he gave a few big reasons why. Not trying to pull an appeal to authority fallacy but if the guy who leads kotlin development disagrees with making it native then maybe that says something but like you said, it's still early in development so I'm still waiting to see what it becomes in the future. I doubt it's gonna be anything like rust, unless there's reason to believe it can compete against rust but whom knows. And in the past I've only been able to find a few blog articles about native and it seems promising but from what I've been hearing from some others and from what I've been reading, it just seems like a lost cause to port kotlin to llvm. But again I don't know that much about kotlin native I'm gonna have to look through it more if I can find some official documentation revolving around how it works and how it's staying as kotlin while switching to a completely new backend

And speaking of back ends, I'd love for Kotlin to support a fourth one: Web Assembly. Rust just added support for it and a "Hello world" program is around 200 bytes (!). Much better than going through Javascript

I just looked back at what I was referencing but I guess I don't know the staff of jetbrains well enough lol what I read was from Alexey not Andrey nor Maxim. I think you know what I'm talking about

Now one thing that I am having trouble with is getting the kotlin native plugin for CLion. I have searched for it in the plugin dialog but to no avail. I installed the latest update so I don't know why I can't find it. Do I have to manually download it to install it or what?

hey, guys, I have some questions recently, I wonder:is possible android framework written in Kotlin in the future?

from one of my gradle projects, it seems that kotlin-stdlib-jre8 1.1.61 is dependent on kotlin-stdlib-jre7 1.1.51, and also kotlin-stdlib-jre7 1.1.61 is dependent on kotlin-stdlib 1.1.51. so in order to use 1.1.61 for all of them, i have to write 3 lines instead of just one line. is this intentional?

@leodeng You don't need to add the dependencies yourself, gradle should figure out them itself from the

.pom

files

Discussion was here https://blog.jetbrains.com/kotlin/2015/03/follw-up-new-class-object-syntax/ …

Does somebody know, why kotlin can’t extend Groovy class, while Java can? It is a bug or feature? https://discuss.kotlinlang.org/t/extending-groovy-class-from-kotlin/1675

Doesn't work it just says Error:(16, 19) Kotlin: Unresolved reference: ListeningExecutorService

@orangy thanks. Will try it. As I said above I'd like to expose public T MyClass.Get<T>()

Hello all, I’m currently picking up Kotlin. I’m looking for interesting OSS projects to contribute to, to help me better learn it. Any suggestions?
