Feels like a Kotlin bug

For the com.intellij.openapi.components.Storage annotation I don't seem to be able to set the value attribute as IDEA is telling me that only named arguments are available for Java annotations. Additionally, value doesn't appear to be available as a named argument. (I determined this was because I was using idea/master rather than idea/143 which I was building against)

Hm really strange, I tried a few things but I can only reproduce it with this particular class. I filed a bug: https://youtrack.jetbrains.com/issue/KT-11389

Guys, when the new 2016.1 is coming? Should I install the EAP, or an update will be here soon?

@voddan: this month

cool! Other the air?

@voddan: BTW, If you could install the EAP and try Kotlin Edu on it it would be great help, cause we are going to release it with 2016.1 and have not so much feedback now

that's what I was thinking about !

thanks for the info!

JetBrains team: what do you think about separate static analyzer based on checks from Kotlin plugin for IDEA? (like pmd, findbugs, etc)

@artem_zin: and a SonarQube plugin also 😄

@nfrankel: well, not a fan of SonarQube to be fair, because it needs a server. As developer I’d like to be able to run all tools that are part of the build process locally, without internet access

You can already run inspections on the command line

Interesting, didn’t know that, but it requires IDE, which is not great

The entire IDE is just a bag of jars, like any other Java-based tool

Right, but I’m not sure I’d like to somehow depend on

306 mb

jar to run static analyzis, especially for CI. Also, not sure but it’ll probably require some project config files which are usually ignored from vcs (maybe not).

Another problem is that it’s not on maven central / etc, it’ll require some distribution infrastructure and kind of

gradlew

to work to avoid committing such big file to vcs. Would be nice to have smal tool with easier setup.

Hi all. I have template like this: val line = """ <- tabs here -> ${generateText()} """ Is it possible to get position of this ${...} to keep formatting (in case multi line result of generateText()?

Or maybe somebody can point me where I can check it in Kotlin source code?

Can I do comparisons in a

when

expression?

No but there is an issue for that in the tracker.

Hi everyone! In my pet project in Java I have A LOT of math with float primitives (some physics). Can anybody tell, if I move to Kotlin, should I expect raising GC overhead due to everything being an object and an immense amount of Floats and Integers created on heap, or all those floats and ints will be just primitives for JVM and will be created on stack?

@mgtriffid: Is GC (possible overhead) add countable value to your project?

Yes, I'm afraid it would cause frequent FPS drops

My game engine (LibGDX) encourages pooling for objects, and I'm using primitives for math. Am a bit worrying about GC if maths started using objects instead of primitives.

"Everything is an object" doesn't mean "everything is a heap reference with virtual calls". Kotlin compiler optimizes out unnecessary boxing/unboxing (that is, allocating primitives on heap).

There are two rather subtle cases, though:

1. If something is a type parameter, it will quite likely involve heap allocation for related data. E.g.,

List<Double>

is compiled to a

List<java.lang.Double>
