Simple command line tool to invert all the colors of a CSS file. Useful for making dark versions of light colored themes

I am someone who hates black text on white backgrounds. It makes me cringe, and my brain has a hard time actually focusing on text.

This was inspired by the Hacker Vision plugin, which does the same thing, only to any page on the internet. I needed a way to do this for my own web creations, as I have spent hours/days/weeks taking a default white theme for a CMS or something and manually transforming it into a dark theme, wishing so badly I could somehow save the inverted color schemes Hacker Vision so effortlessly made. Now I can, and you can too!

This was adapted from code I found in a post here, after searching forever for something like this http://stackoverflow.com/questions/2040848/automatically-convert-css-file-to-be-used-on-dark-backgrounds

To use it, make a copy of your css file ** and rename it to "invert-me.css"**

Then do this:

php css-invert.php 

That's all! Your site.css colors are all now inverted.

###Known issues This formats the code weird on the outputted files, and adds lots of spaces instead of line breaks where they should go.

You should run it through a beautifier like this http://html.fwpolice.com/css/

Also, I don't know php whatsoever.. so my attempt at making this morsel of code work on the command line is ugly and wrong. Any help would be welcome and super appreciated. Please fork and pull at will!
