Xtext Tricks #1: Enhancing Completion Proposals
Those of you who follow me on Twitter might have noticed I am working on an Xtext based DSL for Behaviour Driven Development. Part of the DSL allows the DSL user to define actors and the verbs these actors can execute. Actors can have a hierarchy (much like a class hierarchy), meaning an actor will inherit all verbs of it's super actors. As the list of verbs can grow quite a bit, the content assist drop down menu becomes a bit overwhelming.

Everything You Always Wanted To Know About Modeling (But Were Afraid To Ask)
Does Model Driven Software Development actually work? Are some developers more productive than others? What happens during code generation? Do diagrams and text go together well? What happens during model transformation? What are DSLs? And can I create them with Eclipse? Does modeling scale in the enterprise? You guessed it, these are not the questions from a well-know Woody Allen movie, but questions that will be answered at the Eclipse Modeling

Fun with Regular Expressions: ANT-style variable replacing in strings
I recently felt the need to write a piece of code that resolves ANT-style variables in a string. Suppose you have a property file similar to this one: propertyA=SomeValue propertyB=${propertyA}.SomeOtherValue listofThings=${propertyA}, ${propertyB}, constantValue Let's further assume you want to read property listofThings, and resolve the variables. Isn't that a perfect job for regular expressions? Using Regex Tester, I came up with the following regular expression to find occurrence of ${variable}: \$\{(.+?)\} Using java.util.regex.Pattern and

Google is a truly amazing company and the GooglePlex is a very exciting place to be at. As I was one day early and needed a creative place to put finishing touches on my sli
