A little script for showing the remaining data allowance on EE data SIM

ee-data-usage.rb

#!/usr/bin/env ruby

require 'mechanize'
require 'filecache'

cache = FileCache.new("data-usage", "/tmp", 60 * 30, 3)

unless cache.get('usage').nil?
    puts cache.get('usage')
    exit 0
end

website = "http://add-on.ee.co.uk/status"

mechanize = Mechanize.new

page = mechanize.get(website)
data   =  page.at('#data-usage').at('dl').at('.data-left-value').text.strip
expiry = page.at('#data-usage').at('dl').at('.ends-in-value').text.strip

remaining, allowance = data.split(' / ')
expiry = expiry.gsub("\n",'')
expiry = expiry.gsub("        ",' ')

output = remaining + '/' + allowance
cache.set('usage', output)

puts output

I couldn't find an API from EE for fetching the info, can scrape from the status page however.

Plan to use with dashing
