The Cobra library is a huge one: https://github.com/spf13/cobra

Other stuff worth a look includes:

Tmux: https://github.com/tmux/tmux Kitty: https://github.com/kovidgoyal/kitty Alacritty: https://github.com/alacritty/alacritty

I'm sure there's lots of other stuff I don't know about as well.

It's reasonably fast, compiles down to a simple to distribute binary, and the language is forgiving enough that you can do exploratory programming in it. Go-routines make it especially easy to deal with network calls in it as well. For anything that needs absolute performance though look elsewhere, but even then Go might be a good choice for prototyping.

I actually started learning Go with CLI applications. I have found that https://github.com/spf13/cobra tends to be one of the better CLI helpers you can get into but https://github.com/jpillora/opts is one I have been meaning to try following a presentation I saw on it once.

Large projects like Hugo and Kubernetes have used Cobra to build their CLI tools, and it's fairly light as well even if you need simpler usage. We use it at my workplace simply for wrapping our microservices and the few commands (serve, migrate, etc)

For CLIs - https://github.com/spf13/cobra.

However, will definitely try out Docli whenever I start building something new :)

Tho admittedly it works in reverse; it generates the doc/help info rather than parsing it into an AST. It addresses the “boilerplate” issue with code gen as well, but it has a CLI to generate code that’s pretty powerful.

For instance, how does docli handle subcommands? How about global vs command specific flags? For any case beyond the basic single command CLI, it seems like there would need to be all sorts of magic and non-obvious formatting requirements on the doc string.
