Session Title

Internal DSLs with Xtend



Session Type Tutorial

Duration 45 minutes

Session Description

Xtend, a new statically typed programming language for the Java platform, offers many possibilities for developing concise and intuitive APIs and internal Domain-Specific languages (DSL).

We will start this session explaining the advantages and drawbacks of an internal DSL and how it differs from an external one, e.g. as produced by language workbenches. You will see different real world examples, learn how they are implemented and get an idea about idiomatic usage patterns. From powerful query APIs and declarative UI design to encapsulation of boiler plate code in annotations: internal DSLs with Xtend are fun to work with and can increase your productivity in many Java projects.

Xtend is developed open-source at Eclipse.org, freely available and distributed under the EPL.
