Ruby IDE is all you need to get started with your programming journey with Ruby programming or development with Ruby on Rails web framework to be more practical. There are many IDEs available in the market, both free and paid, and selecting one can be a time-consuming task.

Ruby is powerful programming language but learning and writing code in Ruby is much simpler than most of the other languages. Ruby got all its fame after the Ruby on Rails framework became popular and developers around the globe started using it for web development.

You can get started in a simple notepad, use a feature rich editor like Emacs, VIM, Sublime Text or go ahead with a full featured IDE like RubyMine or Aptana Studio – RadRails.

Which Ruby IDE should you go for?

This is a question that you need to answer based on your liking, development style, requirements and budget at hand. Most of the Ides and editors used for Ruby development are either free or offer a free trial version, so, it is always beneficial to try out a few before closing on to one.

In case you simply want to try Ruby scripting – check out some of the online Ruby Editors like Many of my friends who do freelance development in Ruby language either use Emacs with “Ruby mode and Robe” or VIM for Linux and MacVim with vim-ruby for Mac OS X, and to turn VIM into a perfect Ruby on Rails IDE, they use vim-rails, continue reading for more details on this.

On the other hand, enterprises typically go for RubyMine, which is the most powerful IDE out there in the wild and comes with enterprise grade support. Aptana with RadRails too is quite popular among professional developers and is used widely.

2. VIM – Perfect Linux Ruby IDE (Editor to be precise)

VIM is an old-time classic and those who use VIM, they love it, specially developers who love using keyboard (and only keyboard, no mouse) for lightning fast coding.

VIM is free to use and available under GPL license as open source software. The popularity of VIM can be gauged from the fact that engineers at Facebook have used VIM during the early development of Facebook itself.

VIM is known to be most feature rich free text editor, it can easily be metaphored into a powerful Ruby development environment with right customization and configuration. There are plugins available like vim-ruby for Ruby Scripting and vim-rails for Ruby on Rails web development. If you intend to use VIM on Mac OS X – MacVim with vim-rails & vim-ruby is the way to go along with plugins like Ctrl-P and powerline.

4. Emacs – Ruby Editor cum IDE

Emacs is an absolute stunner and lovable editor for Ruby scripting and Ruby on Rails based web programming, it is available free to use, is GNU and can be customized and configured as per the needs.

Emacs is used by many Ruby developers, and for that reason, there is a dedicated Ruby plugin called enhanced-ruby-mode for supporting Ruby programming.

Sublime Text 3 is a powerful code editor loved by thousands of developers. It also happens to be my favourite code editor and a candidate for all-time best code editors.

Sublime Text 3 core is lightweight, configurable, feature rich, modular and gets its powers via the use of plugins. There are many plugins available out there in the wild that can be used to transform the text editor into a full featured Sublime IDE for Ruby programming.

Ruby is general purpose programming language and is often compared with Python when it comes to readability and easy to understand syntax. Like Python, Ruby is also one of the strong candidates for learning programming, for beginners.

Ruby doesn’t compare with Python in terms of usage since Python has wide spread applications area whereas Ruby is mostly limited to web programming. Because of the limited application area and being a simple language, there are not many dedicated Ruby IDEs or Editors.

If you ask me, Ruby needs just a feature rich good Editor like VIM, Sublime Text, Atom or Emacs. A full features IDE like Eclipse for Java etc. is not really needed for most of the projects.

In this article, we covered most of the IDEs and Editors to ensure that you can find a perfect Ruby IDE for Linux, for windows or a Ruby IDE for Mac.

Let us know your experience with Ruby programming and the best Ruby IDE of your choice via comments, cheers!!
