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.

A faces walkthrough

The VID dialect contains some 20 different faces (graphical widgets), each with its own specific properties (facets). The type of that value specifies what the facet does. For example, a string will be used as the displayed text for the face, or a pair will determine its size. Most faces also have a default action facet, that is, a block of commands that is triggered by a certain event, such as clicking on a button or selecting from a list.

We cannot possibly discuss them all in detail, instead we'll do a walkthrough of the kinds of faces that are available, what you can do with them, and highlight some important properties. You're encouraged to try these out (together with the questions), as we go along.
