Using Cobra for advanced CLI applications
Cobra is a set of packages that allows a developer to create more complex CLI applications. This becomes more useful than just the standard flag package when the complexity of an application causes a list of flags to become numerous.
In this section, we will talk about how to use Cobra to create structured CLI applications that are friendly to developers to add features and allow users to understand what is available in an application.
A few features that Cobra provides are as follows:
