go-gh VS viper

Even simple shell script verbs provide great extension capability for users. For even bigger impact, provide a simple wrapper framework like gh does, that allows extensions written in go to easily call the main tool itself.

So, in general they provide a Go library that works as API client: go-gh. To be frank, the library is still somewhat work in progress and unpolished, and you can't do much with it. This said, the framework they developed to write extensions is quite nice and self-explanatory: you can find an introductory video here by the developers.
