Part 3. Advanced concepts

The concepts and examples become a bit more difficult in this last part, but they should also prove to be a lot more fun.

Chapter 8 looks at Nim’s foreign function interface, which allows you to use libraries written in other programming languages. You’ll learn how to interface with a C library called SDL and then use it to draw some 2D shapes on the screen. You’ll also see the JavaScript backend in this chapter, and you’ll learn how to recreate the same 2D shapes in the web browser using the Canvas API.

Chapter 9 is on metaprogramming. It will teach you about the three different metaprogramming constructs in Nim: generics, templates, and macros. It will also show you how to create a domain specific language for configuration parsing.
