Authenticate a twitter session as per the example at http://twitter.rubyforge.org/, but obfuscate the secrets into a YAML config file.

authenticate.rb

require 'twitter'
require 'yaml'

def authenticate
  
  Twitter.configure do |c|
    config = YAML.load(File.read("config.yml"))[:twitter]
    c.consumer_key       = config[:consumer_key]
    c.consumer_secret    = config[:consumer_secret]
    c.oauth_token        = config[:oauth_token]
    c.oauth_token_secret = config[:oauth_token_secret]
  end

  @client = Twitter::Client.new

end

config.yml

:twitter:
    :consumer_key:       CONSUMER_KEY
    :consumer_secret:    CONSUMER_SECRET
    :oauth_token:        OAUTH_TOKEN
    :oauth_token_secret: OAUTH_TOKEN_SECRET
