I am curious what people reach for when writing CLIs these days; specifically what language, libraries (if any), and why?

By CLI, I mean any executable program or script like git that supports commands, sub-commands, and POSIX-style flags.

I mostly work in Go, and have been happy with the standard library[1] or Cobra[2]. I also write a lot of shell scripts.

I thought it would be interesting to see some other approaches.

I have manually followed DigitalOcean's guides in the past with success[1][2]. Do you go beyond what the linked guides recommend or use a configuration management solution (e.g. Ansible)? I'm curious what, if anything, people are doing.
