Interacting with Twitter is pretty easy in Ruby. First you have to install the twitter gem
gem install twitter
To use this gem you need to register your application with Twitter here to get your CONSUMER_KEY and CONSUMER_SECRET.
The connection to Twitter is established in the following manner
client = Twitter::REST::Client.new do |config| config.consumer_key = CONSUMER_KEY config.consumer_secret = CONSUMER_SECRET end
Now it is very easy to do a search on all recent tweets. The following loop prints all tweets of the last 24 hours containing #hashtag
now = Time.now catch :done do client.search("#hashtag", :result_type=>"recent").each do |tweet| diff = now - tweet.created_at throw :done if diff > 24*60*60 p tweet end end
Based on this I built a little webpage that shows how much is tweeted about german soccer clubs: twuli.de
