Introduction

In this Wiki, several kinds of Integrated Development Environments (IDEs) for Ruby language are shown and their features are compared.

What is Ruby

Ruby is a dynamic, open-source and general-purpose object-oriented programming language with a focus on simplicity and productivity. It has an elegant syntax that is natural to read and easy to write. Ruby supports multiple programming paradigms, including functional, object oriented, imperative and reflective. It also has a dynamic type system and automatic memory management. In Ruby, everything is an object. Every bit of information and code can be given their own properties and actions. Ruby is seen as a flexible language, since it allows its users to freely alter its parts. Ruby’s block are also seen as a source of great flexibility. A programmer can attach a closure to any method, describing how that method should act. Unlike many object-oriented languages, Ruby features single inheritance only, on purpose. But Ruby knows the concept of modules (called Categories in Objective-C). [1]

What is an IDE

An integrated development environment (IDE) (also known as integrated design environment, integrated debugging environment or interactive development environment) is an application software that provides comprehensive facilities to computer programmers for software development. [2] An IDE normally consists of:

a source code editor
a compiler and/or an interpreter (computing)|interpreter
build automation tools
a debugger

Popular IDEs for Ruby

Eclipse

Download Here!

Eclipse is a multi-language software development environment comprising an integrated development environment (IDE) and an extensible plug-in system. It is written mostly in Java and can be used to develop applications in Java and, by means of various plug-ins, other programming languages including Ada, C, C++, COBOL, Perl, PHP, Python, R, Ruby (including Ruby on Rails framework), Scala, Clojure, Groovy and Scheme. [3]

Aptana RadRails

Download Here!

Aptana RadRails is a Rapid Application Development IDE for the Ruby on Rails framework. The goal of RadRails is to provide Ruby on Rails developers with everything they need to develop, manage, test and deploy their applications. Features include source control, code assist, refactoring, debugging, WEBrick servers, generator wizards, syntax highlighting, data tools, and much more. [4] RadRails is now included as part of Aptana Studio 3. [5]

RubyMine

Download Here!

JetBrains RubyMine IDE provides a comprehensive Ruby code editor aware of dynamic language specifics and delivers smart coding assistance, intelligent code refactoring and code analysis capabilities. Easy project configuration, automatic Ruby Gems management, Rake support. [6]

NetBeans IDE

Download Here!

NetBeans refers to both a platform framework for Java desktop applications, and an integrated development environment (IDE) for developing with Java, JavaScript, PHP, Python, Groovy, C, C++ ,Ruby and others. NetBeans IDE is a free, open-source Integrated Development Environment for software developers. All the tools needed to create professional desktop, enterprise, web, and mobile applications with the Java platform, as well as with C/C++, PHP, JavaScript and Groovy. Noting that in NetBeans IDE 7.0, support for Ruby and Ruby on Rails is no longer available in the standard NetBeans IDE build. [7] In the following comparison we will use NetBeans IDE 6.9.
