Clojure for domain-specific languages pdf

This book uses Leiningen, but no prior knowledge of it is required. What you will learn from this book Understand the pros and cons of a domain-specific language Learn general programming design concepts Know the benefits of a Lisp-based syntax Edit Clojure files in Emacs Learn to operate a Read-Evaluate-Loop session from within Emacs Build Clojure projects with Leiningen Manipulate and make polymorphic objects in a non-object-oriented language Create a Twitter domain-specific language to understand Clojure, its Java, and Lisp foundation closely Use your Clojure applications inside of a Java project Approach An example-oriented approach to develop custom domain-specific languages.

Who this book is written for If you've already developed a few Clojure applications and wish to expand your knowledge on Clojure or domain-specific languages in general, then this book is for you. If you're an absolute Clojure beginner, then you may only find the detailed examples of the core Clojure components of value. If you've developed DSLs in other languages, this Lisp and Java-based book might surprise you with the power of Clojure. A general-purpose language like C is designed to handle all programming tasks.

By contrast, the structure and syntax of a Domain-Specific Language are designed to match a particular applications area. A DSL is designed for readability and easy programming of repeating problems. Using the innovative Boo language, it's a breeze to create a DSL for your application domain that works on. NET and does not sacrifice performance. NET by focusing on approaches and patterns. That's right: Lisp was designed to be written in itself.

That means from day one, you could use it, with no dependencies, to write languages in. Languages have this ability to capture an idea in a really elegant way. Humans develop languages naturally. As you gain expertise in a field, you begin to pick up the jargon, the expressions, the turns of phrase. And as you learn to speak it, you learn to think it. The concepts become intuitive. Your language becomes concise, clear, efficient. So why shouldn't our languages let us do that?

Well, I think they should. And I think this feature of Lisp gives it its ultimate power. It's that Lisp knows it's not the best language possible for every use case. But it gives you the tools to build a language that does fit the use case.

If you don't learn as much from this course as you thought, just ask for a refund within 30 days and I'll give you your money back.

We define the terms Interpreter and Compiler, and build a model of how they work. We take a break to set up a Test-Driven Development workflow that we can use from the command line instead of relying on a editor integration. We begin converting our Hiccup interpreter to a Hiccup compiler.

That allows us to do compile-time optimizations. Lisps are wonderfully simple languages. Writing one will teach you the basics of recursive evaluation and how to build a Turing complete language while leaning on the host language.
