Xtend

Xtend is a general-purpose, statically typed programming language for the Java Virtual Machine. It grew out of Java and keeps Java's type system without change, but aims at a more concise syntax. Its additions include type inference, extension methods, operator overloading, lambda expressions, multi-methods and a powerful switch expression, and template expressions, which are multi-line strings with interpolated values and careful white-space handling, suit it to code generation. Xtend source is compiled to Java code, so Xtend and Java files can be mixed in one project and every existing Java library can be used. The language and its Eclipse-based development environment are an open-source project at Eclipse.org under the Eclipse Public License. Xtend originated from Xtext, the framework that defines it, first appeared in the Eclipse Indigo release in June 2011 and has been a standalone project since Eclipse Juno in 2012. It replaces the older Xpand technology and should not be confused with the earlier Xtend language of that project.
