@ilya.gorbunov:

mvn compile -pl :kotlin-stdlib -am

fails with various files in kotlin\maven\*.java, complaining about not being able to find packages like org.jetbrains.annoations, com.intellij.util, etc. This happens even after running the Ant Kotlin dist task. Anything I could be doing wrong?

Does clean build help?

mvn clean install -pl :kotlin-stdlib -am

That helped indeed, thanks!

I've submitted a PR on GitHub, that should be a better place for discussing this: https://github.com/JetBrains/kotlin/pull/821

I faced an interesting scenario: Splitting a stream into two, working with them separately, and then zipping them in the initial order For now I do:

val (As, Bs) = list.mapIndexed { i, it -> Pair(it, i) }.partition { condition(it) }
    
  val Cs = As. map {..}.filter{..}.sortBy{..}

  return (As + Cs).sortedBy {it.second}.map {it.first}

I want a way to generalise it somehow

my first thought would be to use an additional "mapping" stream with indexes, but I can't find a nice syntax for keeping it around

@jw suggested using

flatMap

with

if

in simple cases but in my opinion this lacks the much loved "linearity"

@voddan: what do you mean by "linearity"? And why do think the level of code increases with

flatMap

?

by that I meant the level of nesting lambdas inside one another, as opposite to a linear structure where transformations occur in the order of them being in the code

what's your opinion on adding a

fun <T : Any> listOfNotNulls(vararg items: T?) = items.filterNotNull()

method that combines

listOf

and

filterNotNull

?

Do you mean this one? https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/list-of-not-null.html

Well I'll be damned

I was off by one character

the source urls in the documentation are wrong though

@kirillrakhman: Looks like docs were not rebuilt after RC, thanks for pointing out.

@jacobmoncur has left the channel

@ilya.gorbunov: where is

assertEquals

? The docs on them disappeared. https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.test/

also nothing here https://github.com/Kotlin

where do I get it from? maven?

Sources are here https://github.com/JetBrains/kotlin/tree/master/libraries/kotlin.test, and binaries are distributed with maven http://search.maven.org/#search%7Cga%7C1%7Ckotlin-test

o, hyphen! that was the problem

thank you

@ilya.gorbunov: may a work on this one? https://youtrack.jetbrains.com/issue/KT-7930

i has been a pain for me for a long time

@voddan: A pain, really? You can wrap them until this gets fixed, can’t you?

(and personally, I like the

orNull

approach)

@cedric: I have the same wrapper in all my projects. That's a pain. Don't see your point

It’s already too late to fix them
