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.

In this chapter, you got an overview of the VID dialect for making graphical applications. First, we made a VID version of our download exchange rate app, to see how to use different faces in the view block. We discussed the different options for view for making special windows, and the layout commands such as below, return, and at to structure your screens.

Then, we guided you through a tour of the faces available, such as text, field, button, check, drop-list, panel, tab-panel, slider, menus, and so on. To really build dynamic screens, you have to use actors on these different faces. You learned how to code them, combine multiple actors on one face, detect keys, and make timed events. We also gave an example of how you can start building more complicated maintenance apps. Finally, you got an introduction to the very powerful draw dialect, which enables you to draw 2D...
