@davidgreens ?

1.1 allows

_

for unused parameters of lambda expressions (and it seems also for unused values in a destructive assignments). Why does that not also work for unused parameters of methods? e.g.

fun main(_: Array<String>) {

2 replies hey, beauty is in the eye of the beholder! but really, the intent was the same as in the other usages of `_`: signal the body that we do not want to use this value. But I guess the "what about named parameters?" point means this idea is officially dead.

since the new version yesterday I've got issues just doing a build in IDEA 😕 I get the following exception:

a

mvn clean install

works fine though

any thoughts?

Where I can buy a printed book "kotlin in action" with fast delivery to Russia/Kazan without to pay over 50$ for international delivery?

buy the PDF version (which also includes an epub version). which has the additional benefit of being searchable, easy to copy around (I have one on my iPad and one on my laptop), and does not require killing a tree...

Physical book is nice to have though. I personally went the PDF route as well, have too many physical books already

then but the PDF now and wait for the printed one to show up on eBay in 8 weeks...

I bought the PDF I’m just hoping it’ll be legible on my Kindle

Wish technical publishers would support mobi / re-streamable formats 😕

do epubs work on kindle?

Yes

Is it epub too?

My manager bought the book on my behalf and only gave me the pdf file.

https://www.manning.com/books/kotlin-in-action The $35.99 has it. did your manager get that one?

Yes, I’ll ask him about it tomorrow then.

👍

Thanks

Just purchased the paperback here in the UK, excellent book, loving Kotlin 🙂

@darkmoon_uk They just added ePub and Mobi formats, it was only PDF until a week or so ago

PDF is great, though

Cheers Sergio, I’ve just Calibre’d it onto the Kindle...

Time to find out if it’s legible.

Uh, no.. better chase up that ePub

I’m coming from 9 years of iOS Development, changing to Android, will be using Kotlin.

Largely because its design has a lot of mindshare with Swift.

What’s exciting is; with Kotlin I’ll get a modern language and the ability to interface to so many mature Java libraries.

so I tried updating my sandbox project to 1.1 and now I get this when trying to build:

Error:Kotlin: [Internal Error] java.lang.AbstractMethodError: org.jetbrains.kotlin.kapt3.Kapt3ComponentRegistrar.registerProjectComponents(Lcom/intellij/mock/MockProject;Lorg/jetbrains/kotlin/config/CompilerConfiguration;)V
