Adding a new control structure is usually substantially more difficult than adding a new function or operator. However, when they are effective, the addition of domain control structures is a large part of what makes domain-specific languages worth developing instead of just writing class libraries.

This chapter covers the following main topics:

  • Knowing when you need a new control structure
  • Processing text using string scanning
  • Rendering graphics regions

The first section will help you learn how to determine when a domain control structure is needed. The second and third sections will present two example domain control structures.

This chapter will give you a better idea of when and...
