Libraries For Amazon Web Services (ruby-aws)

• www.rubyforge.org/projects/ruby-aws/

Description¶ ↑

Libraries for Amazon Web Services (ruby-aws) is a set of libraries and tools designed to make it easier for you to build solutions leveraging Amazon Web Services like Amazon Mechanical Turk. The goals of the libraries are:

• To abstract you from the “muck” of using web services

• To simplify using the various Amazon Web Service APIs

• To allow you to focus more on solving the business problem and less on managing technical details

Usage¶ ↑

require 'ruby-aws'
@mturk = Amazon::WebServices::MechanicalTurkRequester.new
puts "I have $#{@mturk.availableFunds} in Sandbox"
@mturk_prod = Amazon::WebServices::MechanicalTurkRequester.new :Host => :Production
puts "I have $#{@mturk_prod.availableFunds} in Production"

For more in-depth example code, check out the samples folder included in this distribution.

Prerequisites¶ ↑

To use the Libraries and successfully run the samples, you must meet these prerequisites:

• You must have an Amazon Web Services (AWS) account. You can sign up at the AWS web site.

• You must have an Amazon Mechanical Turk Requester account. Be sure to use the same e-mail address and password you used when creating your Amazon Web Services account. You can sign up at the Requester web site.

• You must have Ruby 1.8.3 or later. You can download Ruby at the following web site: www.ruby-lang.org.

• You must have RubyGems installed and configured correctly for your Ruby installation. Review the installation instructions here.

  (Note: If installing RubyGems for the first time, you may need to restart your console to pick up environment changes. To execute code that is dependent on Ruby Gems, the command to execute is: “ruby -rubygems program_that_uses_gems”. The “-rubygems” command line parameter should be a default parameter that is always included. To do this, Ruby can utilize the “RUBYOPT” environment label that should be set to “RUBYOPT=-rubygems”. Please refer to documentation specific to your OS on defining environment labels.)

Installation¶ ↑

1. Execute the following command:

   gem install ruby-aws
   

   (Note: Some Unix-based systems may require root access to install Ruby libraries. You may need to execute the above command as the following:

   sudo gem install ruby-aws
   

   and enter in the password to successfully install the Gem)

2. Installation of the ruby-aws gem will prompt to install the following dependent gem if not already installed:

   • Highline

3. (Optional) Download and expand the corresponding tarball/zip file from the project homepage to an installation directory. This will provide you access to the source files, test files and sample code.

4. Configure the Libraries to use your Amazon Web Services authentication credentials by executing the following command:

   ruby-aws
   

5. Verify your installation by running the automated tests by executing the following command in the installation path:

   rake test
   

Running Sample Applications¶ ↑

1. Navigate to the samplesmturk directory of the installation path.

2. Run the various samples
