kotlinlang #announcements

Hm... I had the same impression when I was starting out with gradle, but eventually, when I learned, it became much easier and more readable for me personally to write gradle build files instead of pom.xml

Hello people. A companion object and a static block inside a class, okay? E This block can be implemented in any other class, which inherits from the class that contains this companion object? right?

hi mates, is it possible to call the firebase cloud functions through android ? like we do for general web api calls via retrofit or volley ?

what is the best way to deep-compare two lists in Kotlin today?

i think i may have the version wrong because my release build is failing with

Execution failed for task ':app:transformClassesAndResourcesWithProguardForRelease'.

I've managed to execute an script inside a string from a Kotlin program. But this require to import the kotlin-compiler jar, which is about 30Mb. So, this is too big for an Android project : has someone another solution ?

I thought about Lua first, I just wanted to avoid to use the NDK : the "plugin" I found use the NDK. But I should look further if another project can embed Lua without using NDK

Hi all, is there any release version for kotlin 1.2.10 IDE plugin?

remove

returns the value of the entry removed or null if nothing was removed

I'm assuming I'll have to use flatmap, but I'm terrible at flatmaps so I'm not sure how I'd do it.

Is Kotlin influenced by Swift?

@Shawn That does not work on overloaded function😞

You cannot do that for functions. But there is KEEP proposal about this - https://github.com/Kotlin/KEEP/pull/89

closest you’re gonna get is probably a lambda

val toast = { x: Int -> activity.toast(x) }

why can't I take a varargs array and use operator + on it?

hi, what are reasons to have companion object in class and not a static block(methods, variables) instead?

Thiago

12/13/2017, 1:38 PM

@agrosner Yes. I've tried it several times. However, the error persists.

is there something like swift playgrounds for kotlin? (like try.kotlin, but updating on every keypress, and outputting values for every line)

guys i'm losing hope with an issue - was happening with a gradle build but i've copied the source code into a new standard Kotlin JVM project and it's still happening. I am using IntelliJ IDEA 2017.2.5 but this issue happened after i tried 2017.3 for a brief moment then moved back

Error:Kotlin: [Internal Error] java.lang.NoClassDefFoundError: Could not initialize class org.jetbrains.kotlin.diagnostics.DiagnosticUtils
	at org.jetbrains.kotlin.types.expressions.ExpressionTypingVisitorDispatcher.logOrThrowException(ExpressionTypingVisitorDispatcher.java:243)

already tried everything on this article https://github.com/JetBrains/gradle-intellij-plugin/issues/69

This would be so clean as a when statement though... Unless I'm not reading it right, which is totally possible.

I have the exact same function

glBufferData

in two different locations

import org.lwjgl.opengl.GL15.*

import gln.buffer.glBufferData

is there a way to avoid importing it from the first

import

? At the moment I'm having this in addition:

import org.lwjgl.opengl.GL15.glBufferData as deprecated

but it's meh..

is not so complex for me…

The lambda expression is unused. If you mean a block, you can use 'run {...} '

Thanks, I've read this page, but how can I simply apply these features to generate a function from a string ?

I'm having a strange issue with extending a Kotlin class that implements Iterable. It seems as though when viewed from Java, the implementation clashes with the

java.util

equivalent. Not really too sure what's up!

Hi, what's the most idiomatic way to define and use a custom

toString()

(for debugging purposes) for a java class that doesn't override the one from

Object

interface Debuggable {
   val debugMsg: String
fun <T : Debuggable> debug(name: String): T {
    println("DEBUG: ${name} = ${debugMsg}")
    return this
}
}

@jmfayard This is not my class, I can't add an interface to it. I ended up writing using a

print()

extension function that returns what a proper

toString()

should return for now.

You could also open a proper debugging session, and set breakpoints, so you can see actual values held by the object in question I’m assuming you’re running in an environment where this kind of thing is possible

Hopefully this will become possible if type classes get added to Kotlin (being discussed in a KEEP right now)
