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.

Parsing Data

One of the key focus areas in software development today is working on and analyzing (big) data streams. Every programming language needs to have some support for these kinds of tasks. Most languages use regular expressions (in short, regex ( for such tasks. These expressions match patterns in string data using a specialized formal syntax, which often comes across as an awkward addition to the code.

Red takes a different approach. While Red offers all series operations for working with data, it also has its own domain-specific language (DSL) or dialect called parse, specifically built for text and data processing. The parsing engine is implemented in Red/System. It has its own specific words and syntax, but embedded in other Red code it feels very natural. Parse code itself is much more human-readable and maintainable...
