garbagepatch.js

This is a simple little bookmarklet that checks the global variables in use on a page and attempts to classify them. It's currently very bare-bones, but it's already pretty interesting to check your sites' impact on the global environment, and for deducing what libraries other sites are using.

Using it

1. Copy the contents of bookmarklet.js into the URL field of a new browser bookmark.
2. Click on the bookmark when you're on a page you want to inspect.

Building it

You'll need node.js and uglify-js to run the build script:

# With node.js installed:
npm install -g uglify-js
./build.js       # This will save the new build as bookmarklet.js

TODO

• Detect more popular libraries
• Better output styling
• Add a way to interact with the detected global variables
