Option 1: Command-line download extension as zip and extract

extension_id=jifpbeccnghkjeaalbbjmodiffmgedin   # change this ID
curl -L -o "$extension_id.zip" "https://clients2.google.com/service/update2/crx?response=redirect&os=mac&arch=x86-64&nacl_arch=x86-64&prod=chromecrx&prodchannel=stable&prodversion=44.0.2403.130&x=id%3D$extension_id%26uc" 
unzip -d "$extension_id-source" "$extension_id.zip"

Thx to crxviewer for the magic download URL.

Object Oriented Ideas

Why

• Represent our ideas
• Manage Complexity

Generic OO Terms

• Abstraction - Figuring out what abstractions express our requirements
• Polymorphism - Using multiple abstractions in the same way
• Inheritance - Sharing Implementation
