Decoupling Ruby: Delegation vs Dependency Injection

We’ve all worked with tightly-coupled code. If a butterfly flaps its wings in China, the unit tests break. Maintaining a system like this is…unpleasant. In this article, Jonathan Miles dives into the origins of tight-coupling. He demonstrates how you can use dependency injection (DI) to decouple code. Then he introduces a novel decoupling technique based on delegation that can be useful when DI is not an option.

date-formatter gem - date formatter by example; auto-builds strftime format string

Hello, I’ve put together a new date formatter gem that lets you format dates e.g. “January 02, 2006” using an example as a format string e.g “January 02, 2006” instead of the classic strftime format specifier e.g. “%B %d, %Y”. The date by example adds: String#to_strfime, Date#format, Time#format, DateTime#format, NilClass#format to the built-in classes for easy use. Happy date and time formatting. Cheers. Prost.
