// This is a Greasemonkey user script.
//
// To install, you need Greasemonkey: http://greasemonkey.mozdev.org/
// Then restart Firefox and revisit this script.
// Under Tools, there will be a new menu item to "Install User Script".
// Accept the default configuration and install.
//
// To uninstall, go to Tools/Manage User Scripts,
// select "Oil Standard", and click Uninstall.
//
// UPDATE ON 06/28/18:
// Now the script runs on both Greasemonkey+Firefox setup and Tampermonkey+Chrome setup.
// To install on Chrome you will need Tampermonkey: http://tampermonkey.net/
// In tampermonkey add-on you will need to create a new script and copy paste this code into the editor.
// After saving the script you will need to make sure that the script is enabled in Tampermonkey dashboard.
// We updated the data feed to http://www.cmegroup.com/CmeWS/mvc/Quotes/Future/424/G? which returns a json object

Oil Standard v0.2

XPI GUID {5a4f2051-20a2-42ad-a8bf-d2a23abe24e8}

This is a Greasemonkey script that changes all prices on a web page
into the equivalent value in barrels of crude oil.

A Play on words: Gold Standard... Standard Oil...

Written by Michael Mandiberg (Michael [at] Mandiberg [dot] com)

Lives at http://www.turbulence.org/Works/oilstandard

Oil Standard is a 2006 commission of New Radio and Performing Arts, Inc.,
(aka Ether-Ore) for its Turbulence web site. It was made possible with
funding from the Jerome Foundation and New York City Department of Cultural
Affairs.

BARRELS AND GALLONS
###################

1 Barrel = 42 Gallons

############
INSTRUCTIONS
############

0. Read the entire instructions before installing

1. If you do not have the Firefox browser, you will need to download and
install it from: http://www.mozilla.com/firefox/

2. If you do not have the Greasemonkey extension installed, you will need
to download and install it from here: http://greasemonkey.mozdev.org/

What is Greasemonkey? Greasemonkey is an official extension for Mozilla
Firefox that allows the user to change the look, content, or function of
a webpage, by writing client side DHTML into a page. The Greasemonkey
extension makes Oil Standard possible. You can find out more here

2.5 Restart Firefox (Quit the application and open it again)

3. Click on the link below to go to the Oil Standard script. You should
see an "Install" button on the upper right of your browser window. Click
install.

Oil Standard Script: http://turbulence.org/Works/oilstandard/oilstandard.user.js

3.5 Browsing pages other than Oil Standard: Pages with prices on them!
For Mac OS X, you may need to refresh the pages you are browsing
(sometimes you need to do this twice) For Win XP, and Linux you may also
need to restart Firefox (again!)

4. The first page you browse after installing the script will ask you
whether you want to see prices in Dollars-and-Oil, or Oil-Only. Click
"cancel" for Oil-Only, otherwise, click "OK" or hit enter for Dollars-and-Oil.

Reset Preferences:

Too reset the Dollars-and-Oil, or Oil-Only preference, please visit the
Reset Preferences page, where you will be prompted again to choose.

Disable the script temporarily:

Disable the script via the Greasemonkey menu in the bottom right corner
of your browser. See the little Greasemonkey: clicking on the monkey once
will disable Greasemonkey (clicking again, will re-enable it.)

De-Installation Instructions:

Remove the script by right-clicking (mac or pc)/control-clicking (mac) on
the little monkey, and selecting "Manage User Scripts." From here you can
remove the script.

###########
Change Log:
###########

v0.2	Oil price data source went offline; switched to different source
		Added new month calculation to make sure the script is using the
			60-90 futures price

#############
Known Issues:
#############

When there are mulitple Million/Billion prices in succession, it ignores
every other million suffix.


####################
Future Improvements:
####################

Set up the data retreivals to pull every hour, rather than every page load

Add other currencies in addition to USD
