kotlinlang #announcements

. But I see where you’re coming from and I understand, I was just hoping that something that is used often might be in consideration some syntactic sugaring to get rid of verboseness.

I upgraded Kotlin to 1.1.1 in my Maven project and now Travis CI build fails (only Linux, MacOS works):

[WARNING] The POM for org.jetbrains.kotlin:kotlin-maven-plugin:jar:1.1.1 is missing, no dependency information available
[INFO] Downloading: <https://repo.maven.apache.org/maven2/org/codehaus/plexus/plexus-utils/1.1/plexus-utils-1.1.jar>

https://travis-ci.org/AlexP11223/minic/jobs/217293085 Is it Travis issue? Or I am doing something wrong?

so you then 'mark class as open'

intellij is telling me to remove that true because it is superfluous

This is my 1st class with 1st function Trying to convert a jsonobject to HashMap

bearing in mind all those functions are persistent (ie local factories), can you not write a simple

asIterable()

extension function on your external class?

Quick question - does

when

perform == check or === check when comparing objects? It doesn’t mention on the docs

when (message) {
        removeMessage -> removeItem(subject)
        else -> sendItem(subject, message)
    }

companion object {
        val removeMessage = Message { mapOf<String, String>() }
    }

^^ Answered myself by converting to if

if (it.second == removeMessage) removeItem(subject)
                                else sendItem(subject, message)

Nice idea! I don’t think Slack allows such read-only restricted channels, though. But community here is so good that I doubt it could be a problem. However, announcements often provoke discussions, and though threads are there, they are not very useable tbh. OTOH, we already have #feed, may be just post it there.

Where can I find voting scores for 'Kotlin 20 Future Features kit' - I am curious what the community wants to see

A potential solution could be something like

when (val x = expr()) { is Foo -> x.fooMember() }

, but that’s quite complex

04/03/2017, 6:01 PM

@beholder perhaps you can look at particular example

Are there any plans to support either Higher Kinds, implicits or some kind of typeclass support in Kotlin?

is anyone having trouble getting kotlin-stdlib-js:1.1.2-eap-44 to download with gradle?

orangy

It is a feature, both calls are interchangeable. Essentially function with a receiver is a function with a single parameter, so for simplicity in implementation and some edge cases, lambda with receiver can be called in both forms.

Hi! What’s the best place to chat about IntelliJ issues (unrelated to Kotlin)? Is there an IntelliJ slack or something?

has there been any discussions regarding support for some kind of dependent/abstract types in Kotlin?. something like ...

interface X {
  typealias F
  fun x() : F
}

class Y : X {
  typealias F = String
  fun x() : String = "hello dependent types!"
}

Hi guys, does any one know any library that is similar to factory_girl from Ruby?

Is there a way to distinguish functions with a same name but with a different total signature in KDoc? Say, I have

fun something()

and

fun something(arg: Int)

and I want to link em each other in a docs. Is it possible and how can I do it?

do you know a nice kotlin executive advertisement? i dont need detailled technical stuff but a nice sheet which displays how kotlin is vastly superior on efficiency to the martyrum that is terrible java

Nice idea, but it’s really hard to just guess it

I’m not very familiar with the domain, so I’m asking if it should be #datascience or #bigdata or something else

masted

04/07/2017, 11:16 AM

well, #datascience is a general name of field of science, and #bigdata is a name for a particular archetype in a nowadays industry, both terms are wide, broad and cluttered, but #datascience have a potential boundaries and hierarchy inside, where #bigdata is all about buzz by its nature 🙂

elizarov

#datascience is more general. Most data people work with using the likes of R and Python is not big, but analyzing it is still just a important and the analysis you’d do in Hadoop and Spark

orangy

04/07/2017, 12:04 PM

You are welcome to #datascience

cedric

@orangy In my experience, it's better to not create a specific channel until the general channel gets overwhelmed with this specific topic, otherwise you'll create a dead channel
