DataSift

The official Ruby library for accessing the DataSift API. See http://datasift.com/ for full details and to sign up for an account.

The examples use the username and API key in config.yml unless otherwise noted.

Install Instructions

sudo gem install datasift

Dependencies

If you're using the source you'll need to install the dependencies.

sudo gem install yajl-ruby rest-client

The library will use SSL connections by default. While we recommend using SSL you may disable it if r§equired by passing false as the third parameter when creating a user, or by calling user.enableSSL(false) on the user object.

Simple example

This example looks for anything that contains the word "datasift" and simply prints the content to the screen as they come in.

require 'rubygems'
require 'datasift'
user = DataSift::User.new("your username", "your api_key")
definition = user.createDefinition('interaction.content contains "football"')
consumer = definition.getConsumer(DataSift::StreamConsumer::TYPE_HTTP)
consumer.consume(true) do |interaction|
	if interaction
		puts interaction['interaction']['content']
	end
end

See the DataSift documentation for full details of the data contained within each interaction. See this page on our developer site for an example tweet: http://dev.datasift.com/docs/targets/twitter/twitter-output-format
