# This example constructs a DataSift_Definition object with CSDL that looks
# for anything containing the word "football". It then gets an HTTP
# consumer for that definition and displays matching interactions to the
# screen as they come in. It will display 10 interactions and then stop.
#
# NB: Most of the error handling (exception catching) has been removed for
# the sake of simplicity. Nearly everything in this library may throw
# exceptions, and production code should catch them. See the documentation
# for full details.
#

# Make sure we have some arguments
if ARGV.size == 0
	puts 'ERR: Please specify the words and/or phrases to track!'
	puts
	puts
	exit!
end

# Include the DataSift library

# Include the configuration - put your username and API key in this file
require 'yaml'
config = YAML::load(File.open(File.join(File.dirname(__FILE__), '..', 'config.yml')))

# Authenticate
puts 'Creating user...'
user = DataSift::User.new(config['username'], config['api_key'])

# Create the definition
csdl = 'interaction.type == "twitter" and (interaction.content contains "' + ARGV.join('" or interaction.content contains "') + '")'
puts 'Creating definition...'
puts '  ' + csdl
definition = user.createDefinition(csdl)

# Create the consumer
puts 'Getting the consumer...'
consumer = definition.getConsumer(DataSift::StreamConsumer::TYPE_HTTP)

# Setting up the onStopped handler
consumer.onStopped do |reason|
	puts
	puts 'Stopped: ' + reason

# And start consuming
