Struct embedding trick to avoid duplicate code

When you are writing go code, and try to make it more flexible, most of the time you are looking for interfaces. A go interface is a good solution to make your code more flexible, or scalable, and is also a way to achieve polymorphism. As the official go documentation discusses about interfaces, interfaces are “named collections of method signatures”. So, to implement an interface on different structs, you have to implement each interface’s method for a given struct.

A simple example of how to use Go modules
Generally, when you want to package your go app, you are creating different packages, inside the same project. The problem is, if you want to use a single internal package, you simply can’t, because you have to import the entire package in order to user a single and very simple feature inside. But, sometimes, you don’t want to use a single extenal package. Indeed, you just want to use a certain number of packages to do a task, and all compatible between them.

Or how to make your program OS agnostic... at compile time
Credits to @ashleymcnamara. Recently, I started to use termui in order to build and run a modular dashboard on the terminal. This dashboard will display my daily todo list, some informations about my git projects/repositories, some daily news, etc… I use everyday: a macbook pro, and a GNU/Linux laptop - so, two different operating systems. Even if macOS and GNU/Linux share similar parts, those systems are strictly differents, and I will have to compile the dashboard for each one.
