This is an open review effort to translate Ruby Hacking Guide into English. Some of the chapters are still in preview mode. The guide is organized into four main parts: Objects, Syntax Analysis, Evaluation, and Around the Evaluator. The final chapter explores Ruby’s future. The guide was originally hosted at RubyForge and is now being translated by a group of contributors. You can download the original source code and tool from the official support site of the original book.
