Learn Red ? Fundamentals of Red

By: Ivo Balbaert

Overview of this book

A key problem of software development today is software bloat, where huge toolchains and development environments are needed in software coding and deployment. Red significantly reduces this bloat by offering a minimalist but complete toolchain. This is the first introductory book about it, and it will get you up and running with Red as quickly as possible. This book shows you how to write effective functions, reduce code redundancies, and improve code reuse. It will be helpful for new programmers who are starting out with Red to explore its wide and ever-growing package ecosystem and also for experienced developers who want to add Red to their skill set. The book presents the fundamentals of programming in Red and in-depth informative examples using a step-by-step approach. You will be taken through concepts and examples such as doing simple metaprogramming, functions, collections, GUI applications, and more. By the end of the book, you will be fully equipped to start your own projects in Red.

Evaluating expressions and blocks

Before getting into real programming, we need to see how we can work with Boolean values and numbers. Red is different from other programming languages, in that it does not impose the usual mathematical evaluation order, so we will take some time to investigate that. Furthermore, we will learn how do and reduce are used to evaluate.

Some basic operations

What can we do with logical values and strings, and how do we compare values and variables? Let's look at this in the following sections.

Working with Boolean values
