ozb_notification.rb

#!/usr/bin/env ruby

require 'feedjira'          ## For fetching and parse RSS
require 'yaml/store'        ## For storing viewed items
require 'terminal-notifier' ## For sending a desktop notification
# require 'httpclient'      ## For sending notification to Pushover app on iOS

# We'll use a YAML file to record which items have been sent.
store = YAML::Store.new(File.join( ENV['HOME'] , '.ozb.yaml'))

# Get all entries, select the entries whose id's aren't in the yaml file.
Feedjira::Feed.fetch_and_parse('https://www.ozbargain.com.au/feed').entries.select {|e| store.transaction { store[e.id] }.nil?}.each do |entry|
  TerminalNotifier.notify(entry.title, title: "OzBargains", open: entry.url)
  #res = HTTPClient.new.post('https://api.pushover.net/1/messages.json', { token: '<Your Pushover App Token>', user: '<Your Pushover User Token>', html: 1, message: "<a href='#{entry.url}'>#{entry.title}</a>"})
  
  # Save the ID and URL in the YAML file.
  store.transaction { store[entry.id] = entry.url }
end

The desktop notification one works well. Pretty unobtrusive.
