We have significantly improved the IDE support for Gradle Kotlin DSL scripts (*.gradle.kts files), and we’d like to share some details with you in this blog post. The changes will be publicly available in the Kotlin 1.3.70 release, but you can already try them by joining the Kotlin 1.3.70 EAP (Early Access Program). Some of you may have experienced the following scenario. You have a project built using Gradle Kotlin DSL scripts. You open the build.gradle.kts file to modify the project build logic, but suddenly your computer starts burning through CPU, your script looks like plain text (with

This year at KotlinConf 2019, Roman Belov gave an overview on Kotlin's approach to data science. Now that the talk is available for everyone to see, we decided to recap it and share a bit more on the current state of Kotlin tools and libraries for data science. How does Kotlin fit data science? Following the need to analyze large amounts of data, the last few years has brought a true renaissance to the data science discipline. All this renaissance of data science couldn't be possible without proper tools. Before, you needed a programming language designed specifically for data science, but

This is a guest blog post from Paul Merlin software engineer for Gradle The recently released Gradle 5.0 includes the Gradle Kotlin DSL v1.0 which is now ready for widespread use. We want you to enjoy a build authoring experience with the benefits provided by Kotlin’s static type system in Intellij IDEA and Android Studio: auto-completion, smart content assist, quick access to documentation, navigation to source and context-aware refactoring. https://gradle.org/images/hello-kotlin-2.webm To view the video in Safari you may need to install the VLC Web Browser Plugin.

  You can read this blog post in other languages:   Today we are releasing Kotlin 1.3 together with a set of accompanying libraries, build tools, and learning materials! We develop Kotlin to be a good tool for all application developers, at all scales and on all platforms. In Kotlin 1.3 coroutines graduated to stable, making non-blocking code easy to read and write. Scalability has never been as approachable before! This release also brings Kotlin/Native Beta that compiles Kotlin code directly to native binaries. The multiplatform capabilities of Kotlin now cover all supported

In today's keynote at KotlinConf 2018 we made a series of announcements around releases, resources, and other things we've made available. For your convenience below is a brief summary of the announcements with the corresponding links for more information. Kotlin 1.3 hits RC Version 1.3 hits RC and brings a ton of new features and functionality. Coroutines Kotlin Coroutines are no longer experimental. Check out the Overview page with more information on how to get started Multiplatform Projects Take advantage of Kotlin's code sharing abilities across platforms with Multiplatform Proje

We are happy to announce the 0.8.2 release of Kotlin/Native. In addition to the bug fixes and improvements, we have introduced support for Kotlin/Native Gradle projects directly in CLion! (more…)

fun main(args : Array<String>) { println("Hello Kotliner!") println("Click this green button at the top right!") } Oh yes, this is a runnable Kotlin snippet embedded right in the blog post. Note that you can not only run it, but you can also change the code: // The code below doesn't compile. Add only one char to make it runnable again fun main(args : Array<String>) { val fix = "Kotlin " val me = "is great" println(fixme) } Cool, isn't it? Note that completion works too. Often you don't want to show all t

Greetings Kotlin fans! Ever since we announced interoperability with Objective-C for Kotlin/Native, we’ve been getting lots of questions about IDE support that would allow working on projects that mix Kotlin/Native and Swift/Objective-C. Today we are happy to announce that we are working on a Kotlin/Native plugin for AppCode! AppCode is our macOS-only IDE designed for iOS/macOS developers. It already supports the Xcode project model, running and debugging in simulators and on devices, and offers extensive support for Objective-C and Swift. So, it felt natural to add Kotlin/Native support to

We are pleased to announce Kotlin/Native v0.6 (Valentine’s Day release) of our toolchain. This is a major update, including the following features: Support for multiplatform projects in compiler and Gradle plugin Transparent Objective-C/Kotlin container classes interoperability Support first embedded target (STM32 board) Kotlin 1.2.20, Gradle 4.5 and Java 9 supported Smaller WebAssembly binaries (basic applications is around 160KiB now) CLion plugin update for CLion 2018.1 (fixed the issue with macOS platform libraries indexer) (more…)

This is a guest blog post from Eric Wendelin software engineer for Gradle A build cache allows Gradle to reuse task output from any previous invocation, including those from other machines. Kotlin 1.2.21 allows Kotlin projects to make use of build caching. The build cache works by storing compiled classes, test outputs, and other build artifacts in a cache, taking into account all task inputs, including input file contents, relevant classpaths, and task configuration. This frequently results in faster builds. The following chart shows aggregated build time with and without the build ca

Greetings Kotlin fans, A New Year is coming and we are truly happy to make the last announcement of 2017. We’ve just released the update for Kotlin/Native plugin for CLion. It brings support for Kotlin/Native platform v0.5 which was published recently. Your feedback is very important for us. Please report bugs and issues in the Kotlin bug tracker. Your questions are welcome on the #kotlin-native channel on Slack (get invited here). Wishing you all the magic and a happy New Year! Have a nice Kotlin!

Kotlin/Native is a brand new technology that compiles Kotlin directly to machine code and produces executables that can run without a virtual machine. At KotlinConf 2017, we announced a preview release of development tools for Kotlin/Native. While we have IntelliJ IDEA for working with Kotlin, Kotlin/Native integrates with technologies from the native world such as Clang and LLDB support. That's why JetBrains' choice for Kotlin/Native is CLion, our IDE for C and C++. To get started, download and install CLion 2017.3 (note that this version is at the early access preview stage for now). Next,
