Is it possible to get class’s qualifiedName as a compile time constant? For example, to use in in annotations:

@Qualifier(value = MyClass::class.qualifiedName)

or #coroutines, depending on meaning!

In a Run Configuration, how can I force IDEA to take file changes into account? I would like to have a run configuration doing 1) run webpack 2) make IDEA see files changed by webpack 3) Start Ktor, taking client file changes into account

hey, given I have variable of type function, is it possible to know if the function currently is computing given this reference variable?

@sabag.ronen

reified

in Kotlin only reifies classes, but it does not reify types. Now

String

and

String?

are different types, but they have the same class.

(see how you access

T::class

, there is no

T::type

so far)

Hey guys, I made an app using google vision that recognize a text either through picking an image from galery or taking pictures with the camera. The thing is I am trying to improve the "mathematical side" so it will be able to recognize signs (+ -) and number properly. But the way it is right now is far from good. Any idea about how can I improve this?

Hey Jetbrains team I would like to address the certain problem which exceeds a scope of single ticket/issue and I believe it deserves an attention from Kotlin team. In general, I am talking about Kotlin templates that currently are unusable for multiple reasons. My task seems to be simple -

create 2 templates, one for test class and one for test method

. First of all, I tried to setup Kotlin specific template for

Junit4 Test Method

template, but there is none. Yes we can use java code that will be converted into Kotlin, but we would lose some Kotlin specific constructs like

latent

...but, unfortunately even Java version does not work at all https://youtrack.jetbrains.com/issue/KT-22937 I also tried to generate whole test class from

Junit 4 Test Class

template, but again lack of Kotlin specific language constructs and J2K conversion process makes use of templates a bit unpredictable and problematic eg. I want lateinit and yes I want empty class with empty body (J2K removes this body, but I need it to add tests there) https://youtrack.jetbrains.com/issue/KT-22120 Since both of above

code templates

failed to generate proper test method/class I started looking into live templates as a hack or way around the problem. I was able to create a template for generating test method. With test class template I used

groovyScript expression

(painful to implement, annoying to test, impossible to debug?) to process some strings but still failed a bit because I was not able to retrieve the path of the current file to generate the proper package name (for empty Kotlin file where I want to use this template). I described my ‘get file path’ problem on 3 separate groups, 0 answers… My point here is that in Kotlin there are multiple problems with Kotlin code/file/live templates and currently templates are unusable or VERY difficult to use. I think someone should look at it at ‘bigger picture’ and try to fix “Kotlin-template user experience’

@jamie-purchase you need to update dependencies section of build.gradle (add used dependency there). Gradle supports adding dependencies from repositories and also from local files system (if jar-library was built locally and was not published as artifact)

or

fun Any.foo() = javaClass.name

If I was actually returning the class name here yup -- in reality I need to apply some other logic on the

Class

Hi! Anyone here with active github accounts registered a year ago or earlier? I want these tokens https://gist.github.com/c-darwin/a9a96a4eaae16c0d410f34e434594132 They don't sell them, that's why I'm looking for people having veteran github accounts to place my ECDSA keys there. I can pay for your help, please PM me. Thanks!

Hi! I want to write extension for firefox with kotlinjs and java. I try to open file and rename file name using java.io.File.Is it possible?

I read in a few places that Kotlin will bring inline classes in the future (i.e. zero overhead API wrapper on a single type, primitive or not). Just wanted to tell that I know it'd be super useful to write great DSLs on top of legacy designed APIs (e.g. Android)

How do I use

@ClassRule

i n kotlin?

@ClassRule
    public static Neo4jRule neo4j = new Neo4jRule();

I tried

@ClassRule
    var neo4j = Neo4jRule()

but it says

The @ClassRule 'neo4j' must be public

I did this

companion object {
        @ClassRule
        @JvmField
        val neo4j = Neo4jRule()
    }

now I get this error:

org.neo4j.server.ServerStartupException: Starting Neo4j failed: Component 'org.neo4j.server.database.LifecycleManagingDatabase@6778aea6' was successfully initialized, but failed to start. Please see the attached cause exception "io.netty.handler.ssl.SslContext.newServerContextInternal(Lio/netty/handler/ssl/SslProvider;Ljava/security/Provider;[Ljava/security/cert/X509Certificate;Ljavax/net/ssl/TrustManagerFactory;[Ljava/security/cert/X509Certificate;Ljava/security/PrivateKey;Ljava/lang/String;Ljavax/net/ssl/KeyManagerFactory;Ljava/lang/Iterable;Lio/netty/handler/ssl/CipherSuiteFilter;Lio/netty/handler/ssl/ApplicationProtocolConfig;JJLio/netty/handler/ssl/ClientAuth;[Ljava/lang/String;ZZ)Lio/netty/handler/ssl/SslContext;".

is creating a

companion object

and

object

similar in some sense?

Guys which one is better for creating a singleton class in kotlin? Just like in plain old java using

abstract

class or

object

?

So I've run into an issue that works in Java, but I can't figure out how to make it work in Kotlin. Specifically, I'm trying to create an empty instance of an enum set given a type reference. Context for this is a custom deserializer to map null to empty set. Here's the code that works in java (type is a CollectionType)

Class<Enum> enumType = type.getContentType().getRawClass() as Class<Enum>
EnumSet.noneOf(enumType)

However, the kotlin version does not like the types if implemented as followed

val enumType = type.contentType.rawClass as Class<Enum<*>>
EnumSet.noneOf(enumType)

The error kotlin displays on the noneOf call is about Enum<*> not being a subtype of Enum<Enum<*>>. Is there any way to make this work? Thanks!

I'm looking for help migrating ButterKnife with KotterKnife

swap

map

and

observeOn

order

(I don't want to use a sealed class for just this emptiness case)

ok, I got it. But why such design decision in kotlin? I mean, most of developers (i think so) are comfortable with exclusive reanges by default

Hi, Do you know if there is an idea channel for intellij idea plugin development? Thank you in advance.

Hi, Is there a good reason for Idea 2018.1 eap considering 1.2.30-eap-60-IJ2018.1-1 as a stable version in configure kotlin plugin updates dialog? In fact I noticed that Idea considered this installed plugin as the latest regarding the selected channel. I would like to use the stable version of the kotlin plugin in EAP versions of Idea 2018. Do I have to go on the path of reinstalling the plugin? Thank you

what it takes to bundle kotlin compiler as part of my program, in case if I want to be able to compile user provided "configs" written in my kotlin DSL?

It doesn't matter how you instantiate it, that function says N is a

BaseNavigator

. Unless

BaseNavigator

is a subclass of

NavigationController

(it's not, you have it the other way around), that won't compile.

Blame the company with the dumbest pricing scheme in history - Slack.

It is possible to create an object by lazy delegation passing a parameter to the object in a static context?

I'd have called it

map

.
