Kotlin Goes Open Source!

We are happy to announce that Kotlin, a modern programming language for Java and JavaScript platforms developed by JetBrains since 2010, has just gone Open Source!
In addition to Kotlin Web Demo, a web-based environment for editing, running and sharing Kotlin programs, we’ve opened access to snapshot builds and source code (under the Apache 2 License) of the following:

  • The Kompiler — Kotlin compiler,
  • Enhancements to basic Java libraries — convenient utilities for JDK collections and more,
  • Build tools — Ant and Maven integration, and
  • IntelliJ IDEA plugin — Kotlin’s native IDE.

We invite you to try Kotlin and give us your feedback, ideas and suggestions. Solve problems proposed on Web Demo and share your solutions with the world.

We are also looking for Kontributors, i.e. Kotlin contributors — brave souls eager to make this world a better place together with us. All Kontributions, from compiler to IDE patches to libraries and examples, are welcome and appreciated. You can start by reading our issue tracker or by just picking your favorite library and making it Kotlin-friendly.

Read more on http://jetbrains.com/kotlin
Our issue tracker: http://youtrack.jetbrains.com/issues/KT
The source code is available at http://github.com/JetBrains/Kotlin

Note that Kotlin is still under development. You can download snapshot builds here: https://github.com/JetBrains/Kotlin/downloads.
Attention: Latest builds of IntelliJ IDEA are required for running the plugin.
