Simple Ruby Vote Script

In this tutorial, I will show you how to create a very simple vote script in Ruby using Radiator.

Requirements

• Ruby 2.0+
• Radiator 0.2+ (by @inertia)

Screencast

Text Walkthrough

• Open a new file in your chosen text editor
• Add a shebang line to the file
  • #!/usr/bin/env ruby
  • this will allow your system to locate the ruby executable via your user path
• Require the 'radiator' gem
  • require 'radiator'
  • make sure to run gem install radiator if you haven't already
• Create the class method
• Define basic variables
  • STEEMUSER, STEEMKEY, STEEMRPC
• Define the initialize method to pass variables
  • author, permlink, weight
• Add an attr_reader line containing the variables we will use to vote
• Define the vote method and accept the above variables
  • initialize the transaction via Radiator
  • create the vote transaction hash
  • add the transaction hash to the radiator operations
  • process the operations and print the output to STDOUT
• Finally, add the line that will call the newly created vote method on the Bot class

Execute the Script

./vote-example.rb '{"author": "netuoso", "permlink": "simple-ruby-vote-script-tutorial-with-screencast", "weight": "100"}'
