Eclipse Xtend on JVM: Not as 'scary' as rival Scala

Co-architect Sebastian Zarnekow discusses Eclipse.org's statically typed language, benefits of compiling to Java source

By , InfoWorld |  Software, java

Eclipse.org's Xtend language is all about modernizing Java apps. At least that's the view of Xtend advocates, who say that the statically typed language, which runs on the JVM (Java Virtual Machine), removes unnecessary syntactical noise, is easy to learn, and lets developers enhance existing Java APIs through extension methods and lambda expressions.

InfoWorld Editor at Large Paul Krill talked with Xtend co-architect Sebastian Zarnekow about Xtend following Zarnekow's presentation at the JavaOne conference last week in San Francisco. The senior software architect at Itemis, which specializes in model-based software development, expanded on the benefits of Xtend, including why it is less complex than Scala, the increasingly popular statically typed JVM language that Zarnekow called "scary."

InfoWorld: What was the genesis of Xtend?

Zarnekow: We started the Xtend project as a proof of concept that real programming languages can be created with the Xtext framework [for domain-specific languages]. The vision was having something that simplifies the life of a Java developer while being able to address the issues that Xtend [the previous language of the same name] and Xpand [template language] addressed.

InfoWorld: What's the difference between the old Xtend and the new Xtend?

Zarnekow: The old Xtend was the brother of Xpand, so it only provided extension methods, whereas the new Xtend is a complement to Java and the successor of Xpand and the old Xtend.
