@ijp If compiling a simple Java file takes 15 seconds, I strongly suspect something wrong with your environment (defective hard drive maybe?). Have you tried to build on another computer?

Hi everybody I created a project on git hub to of an extention for java.util.File class adding methods to delete after few seconds. How i'm new in Kotlin and here, I would to know if anyone could take a look mainly on code and tests case and which is the best channel on slack to publish

Please check 1.1.2 EAP in #eap channel, your project might be important for quality! 📣 📣

does anybody know why "JvmField cannot be applied to property defined in companion object of interface"?

When creating a collection or a list do you always need to specify the type of whatever is in those structures with <>? (like Collection<Int>). Can't you make a list that has both Int and Strings?

Package-private and testing shouldn't have anything to do with each other tho. Test what's public.

Please file a kotl.in/issue

Because JMM. https://shipilev.net/blog/2014/safe-public-construction/

@orangy Thanks, I'm comfortable if I have to figure it out looking at the code. Regarding the

all-open

plugin, do you know where it actually performs either the AST transformation or class rewrite to open it? I have not been able to find the sources for that part and that could help me get started.

Any way to force use of named parameters on

copy

for certain data classes? I have a class where first two props are `Int`s and wanted to change the second, but forgot to use name of property. Found after like 5 minutes.

Is it possible to set up hot-swap for JavaFX development? What I have in mind is moving around components while the app is running by recompiling some classes.

I'm planning to implement kotlin script runner for my web application. It will work like this: On the web there is an editor with a text area where one can write a Kotlin script, then this script is autowired from running Spring context and then executed. I want it to be nice, so I decided to implement a web-ide style editor, with syntax highlighting and auto-complete for both language features and existing Spring beans (maybe). So I'm looking for a minimal but extendable web-ide for Kotlin. So far I've found out that try.kotl.in is open-source, and therefore I could strip it down to bare bones that I need and use that, but before I dive down I'd like to know, maybe there is something more atomic, which I can just take instead of digging it out of a larger project?

I’m looking for some more examples of how to use the

provideDelegate

operator. The example code on the documentation is slightly confusing: https://kotlinlang.org/docs/reference/delegated-properties.html Does this create an instance of

ResourceLoader

which then creates the delegate? Will the

ResourceLoader

be gc’d after it’s created the delegate? It also mentions it can be done with an extension function, but there is no example of this.

wow.. adding a dependency for a "two-liner" smells awful lot like javascript and npm 😄

What in the world would cause “unresolved reference: kotlinx” and “unresolved reference: list” to start appearing?

can someone point me on how I can extend a data class? as per the documentation

Since 1.1, data classes may extend other classes

.? I am trying to achieve

data class Person(val name: String)
data class Employee(val id: String, val name:String) : Person(name)

So... Is there a way that I can pass in Javadocs so that something like java.util.function.Consumer becomes Consumer with a hyperlink to the oracle docs/

Tricky question: is there a way to tell my code that some Java type is covariant?

Yes. And I do know many of the pros and cons of tabs vs spaces, for my team tabs win 🙂 I'm not saying it's like that for everyone, but give me my options!

inCompilationProduct.toCompiledProduct().shouldEqual(expected)

using Kluent. I’ve tried with assertEquals from Junit just to be sure it wasn’t something Kluent was doing, but it isn’t.

why is it that when you want to update the idea kotlin plugin you have to go find it in the list of jetbrains plugins rather than just hitting check for updates?

without a way to downgrade the intellij plugin to 1.1.1, my project no longer compiles in intellij. that’s the kind of lock-in I’m always afraid of (got burned too many times with groovy + eclipse in the past).

Oh I get it, thanks 👍

@firezenk I don’t see how meme image like this contributes to Kotlin community. If you have complaints, please share them and be specific.

Missed it, now I'm insanely curious what was the image everyone is talking about 👿

I have suddenly started getting error when building my KotlinJS project in Idea 2016.3 (Kotlin plugin 1.1.1): Error: Kotlin: Source file or directory not found. Maven builds works fine. Any idea how can I turn more logging for kotlin compiler? There is no other error than this in the Idea logs.

I change it manually because of course, but I always have to remind my teammates

is there a way to get IntelliJ to show type info for an expression?
