Sometimes, in more complex projects, a rift builds: the developers do their best to interpret the business logic the customer demands, but inevitably fail to bridge that gap. It's a solid bet that most InfoQ readers will have experienced this in some format or another in their work life. As always with Ruby, there is another way. Domain Specific Languages - DSLs - provide the backdrop to create business focused syntax that better matches customer needs.
To help you get to grips with creating your own DSL, Obie Fernandez (InfoQ's lead Ruby editor) shows you how to build a draft DSL implemented via Test Driven Development in our exclusive presentation from the JAOO conference in Denmark, which is a top tier yearly developer conference.
