Starting Ruby development – Day 1 – Install Ruby and Aptana IDE

In the following days I will cover how you can quick start your Ruby learning. Today we will start with Ruby installation and IDE setup.

The first thing you need is a decent IDE so that you can quickly try out Ruby programs. Ruby installation comes with command line tools such as “irb”. But for any real development, a good IDE is necessary. In this example, I will use Aptana IDE which is based on RadRails.

Step 1 : Download and install latest Ruby release.

Step 2: Download and install Aptana IDE.

Step 3: From Aptana IDE, install Ruby extensions (you can exclude rails extensions for faster install). From Aptana, click on Help->Software Updates->Find and Install->Search for new features for install.

Step 4 : Create a Ruby project from Aptana IDE. You can keep all the sample Ruby programs you write here.

Step 5: Write the following sample code in file named “HelloWorld.rb” and click on “Run HelloWorld.rb”. You should see your first Ruby program output!

class HelloWorld
  def doHello()
    puts "Hello World"
  end
end

HelloWorld.new().doHello()
