DSLs in Boo

Chapter 3. The drive toward DSLs

In this chapter

• Understanding DSL types
• Building a DSL for scheduling tasks
• Fleshing out a DSL syntax
• Taking a DSL apart to see what makes it tick

In this chapter, we’re going to look at the different types of DSLs that we can build and at how and when we should use them. We’ll then take a problem—the need for a scheduling system—and begin solving it with a DSL—the Scheduling DSL. We’ll start by looking at the problem, follow the reasoning that leads us to solving it using a DSL, and then decide on the syntax and implementation.

In this chapter, we’ll build several implementations of the Scheduling DSL and go through the entire process of building a DSL for real use, although ...
