Cookbook

The Cookbook is a community-created collection of practical examples, guides and advice for accomplishing common tasks in D. Here you can find knowledge and insight based on experience and "what works". ⚠ One should keep in mind that, while the goal of the Cookbook is certainly to establish best-practices and inspire developers to write proper D code, it also strives to help get things done, and as such may take a more pragmatic approach than normal documentation. The Cookbook is not a shortcut to learning D. The reader is adviced to read the official D documentation as well.
