What is Ruby?

Ruby is a general purpose programming language, invented by a Japanese programmer Yukihiro Matsumoto. The majority of design work was done back in 1990s, however, the language popularity took off ten years later, in 2006, with Ruby gaining worldwide acceptance.

The official Ruby's website, http://www.ruby-lang.org, describes Ruby as "a dynamic, open source programming language with a focus on simplicity and productivity," adding that "it has an elegant syntax that is natural to read and easy to write."

No modern language can effectively be used without an Integrated Development Environment (IDE), and Ruby is no exception. Below is an overview of three popular IDE choices for Ruby language.

Overview of Ruby IDEs

There are three popular choices when it comes to Ruby IDEs: Aptana plug-in for Eclipse, NetBeans for Ruby, and RubyMine. While all three bundles provide basic IDE functionality and offer seamless integration with Ruby's interpreter, there are many notable differences in their architectures, core features, and other aspects, as briefly summarized below.

Aptana (Eclipse Plug-in)

Developed by: Aptana, Inc.
Current Version: 1.5
License: GPL (free), Proprietary
Operating System: Cross-platform
Website: http://www.aptana.com/

Unlike its competitors, Aptana is not a true IDE package, but is merely a plug-in for a very popular Eclipse platfrom. Installing Aptana is not as effortless as setting up the other two IDEs, simply because it must follow a successful Eclipse install. Once Eclipse is up and running, the plug-in can then be added.

Being an extremely lightweight platform, Eclipse has no official hardware requirements list. It is known to run on almost any hardware configuration while supporting dozens of OS platforms, from Windows to Linux to Mac OS. Consequently, a minimal hardware setup that is required to run Aptana is also very forgiving:

Processor: Intel Pentium Intel Pentium IV or equivalent
Memory: 512 MB

In order to take advantage of Aptana's features, one would need to switch Eclipse to a "Ruby prospective", therefore, letting Aptana to take control over the IDE. Among the features offered by the Aptana Studio package, its developers list the following:

Full support of "Ruby on Rails and loads of popular gems"
Instant Code Assist
Syntax Highlighting
Various Views
And many other features...

Aptana Studio is an excellent IDE choice, given that, in addition to using it for Ruby development, you plan on using Eclipse with other programming languages.

NetBeans

Developed by: Sun Microsystems
Current Version: 6.7
License: CDDL (free)
Operating System: Cross-platform
Website: http://www.netbeans.org/features/ruby/

NetBeans for Ruby is a free, cross-platform IDE based on customizable and easily expandable NetBeans framework by Sun Microsystems. This platform is known primarily for being a foundation of a very popular Java IDE bundle. Unlike Eclipse, which supports Ruby through plugins such as Aptana, Sun Micosystems decided to release a standalone Ruby-focused toolset.

The latest version of this IDE can be found at http://www.netbeans.org/downloads/index.html. The installation is very straightforward, given that your hardware meets the following modest hardware specifications:

Processor: Intel Pentium III 800MHz or equivalent (Intel Pentium IV 2.6 GHz recommended)
Memory: 512 MB (2 GB recommended)
Disk space: 750 MB of free disk space (1 GB recommended)

According to NetBeans.org, the following major components are included in the NetBeans for Ruby bundle:

Ruby Source Code Editor
Ruby and Rails Debugger
Support for Ruby projects
Ruby Gems Installation Manager

This option is a great choice when one plans on sticking with Ruby projects. One downside of this environment is that it may feel a little sluggish on slow computers due to its high hardware requirements. However, it should work just fine on the majority of modern PCs.

RubyMine

Developed by: JetBrains
Current Version: 1.1.1
License: Proprietary
Operating System: Windows, Mac OS X, Linux (cross-platform)
Website: http://www.jetbrains.com/ruby

RubyMine is a Ruby IDE that is being developed by JetBrains. It is advertised as "The Most Intelligent Ruby IDE" due to a variety of offered features, focused solely on Ruby. Here are a few of its key components:

Intelligent Editor, supporting code completion, automatic refactoring, and other techniques.
Error-Free Coding, essentially an automatic code analysis performed during the code design phase.
Advanced debugging tool
Full Ruby on Rails support
And more...

In order to have a trouble free experience, your computer should meet minimal recommended specs outlined below:

Processor: Intel Pentium III 800 MHz or equivalent
Memory: 256 MB (1 GB RAM recommended)

Similarly to NetBeans, RubyMine is a good pick as a primary Ruby IDE. Just like the other IDEs, it is written in Java, so one would need to keep in mind that a speedy PC is a must, to be able to run JVM comfortably.
