Simple macOS app that allows you to drag and drop anything and inspect the pasteboard types. It was written using RubyMotion.
A built application can be found in the bin folder. If you have RubyMotion installed, then you can change to the folder and run rake from the command line.
After starting the app, drag anything (a webpage image, text, etc) into the drop rectangle. You will then be shown the Pasteboard types for that object.
For example, dragging the address bar link https://www.apple.com from Safari will generate
the following output:
https://www.apple.com/
