Domain Specific Languages (DSLs) are becoming more and more popular, allowing developers to express their intent more precisely and with less syntactic noise. DSLs can be built on top of a host language (like Java or Ruby), which are referred to as "internal DSLs". External DSLs are far more flexible in terms of language design: you can define any desired grammar, you can define domain specific constraints and error messages, and you can process the DSL in a concise manner because it can either be interpreted or transformed into the code of any language by a generator.

TMF Xtext, which is a part of the Eclipse Galileo release, is a framework for developing textual domain-specific languages. Given an EBNF-style grammar, Xtext automatically generates an Ecore meta model and a rich-featured, fully configurable text-based DSL editor including features such as syntax highlighting, hyperlinked reference navigation, reference look-up, code completion, formatting, an outline and so on. The default implementation can easily be customized.

In this session Peter will explain what DSLs are and why you should care about using them. After a short introduction, he will show how to develop DSLs with TMF Xtext, which is a part of this year's Galileo release. You will learn how to define a grammar for a DSL and create a full-blown editor for this DSL, featuring code completion, syntax highlighting, hyperlinking, a semantic outline and more. Peter will also show how to write a code generator that allows you to transform your DSL scripts into running software.

Xtext is a component in the Modeling/TMF subproject and makes the development of textual domain specific languages (DSLs) straightforward. Just describe your very own language using Xtext's simple EBNF grammar language and the generator will create a parser, an AST-meta model (implemented in EMF), as well as a full-featured Eclipse text editor from that. The Framework integrates with technology from Eclipse Modeling such as EMF, GMF, M2T and EMFT. Development with Xtext is optimized for short turn-arounds, so that adding new features to an existing DSL is a matter of minutes. Still, sophisticated programming languages can be implemented.

In this webinar we will explain what DSLs are and how you can benefit from them in today's software development projects. Language development is no longer rocket science. To prove this, we will demonstrate how to implement a simple DSL for ordering sandwiches, including a parser, code completion, navigation and an outline view. The webinar closes with some more advanced show cases to give a glimpse of what Xtext is able to do.

Some of the examples from the webinar are also available:

• Domain Model and Index
• Xtext and GMF

Not long ago the notion of a tool that hides more of the program than it shows sounded crazy. To some it probably still does. But as Mylyn continues its rapid adoption, hundreds of thousands of developers are already part of the next big step in the evolution of the IDE. Tasks are more important than files, focus is more important than features, and an explicit context is the biggest productivity boost since code completion. This talk discusses how Java, OSGi, Eclipse, Mylyn, and a combination of open source frameworks and commercial extensions like Tasktop have enabled this transformation. It then reviews lessons learned for the next generation of tool innovations, and looks ahead at how we are redefining the “I” of the IDE.
