Ruby Programming

From Wikibooks, the open-content textbooks collection

Ruby is an interpreted, object-oriented scripting language. Its creator, Yukihiro Matsumoto, a.k.a "Matz", released it to the public in 1995.

The book is currently broken down into several sections, and is intended to be read sequentially. Getting started will show how to install and get started with Ruby in your environment. Basic Ruby demonstrates the main features of the language syntax. The final section, Intermediate Ruby covers a selection of slightly more advanced topics. Each section is designed to be self contained. Finally, the Ruby language section is organized like a reference to the language.
