getoptions VS cobra

I like to use https://github.com/ko1nksm/getoptions

A lot of people have been looking for a best practice to use getopt and getopts for long years. A number of methods to parse arguments were thought up, but no perfect solution was found. However, with the advent of the getoptions, that long journey comes to an end.

Why not use a library instead of implementing it yourself? I wrote getoptions (not getopt or getopts) which many option syntaxes can be easily supported. A lot of options are no longer an obstacle, and there is no need to use another inappropriate language for such a trivial reasons.

We can use the flag with --date or -date, Go already does the automatic check. We can make our entire boilerplate with this approach, but let's make it a little easier and use the Cobra CLI package.

In this tutorial, we'll walk through the process of creating a simple command-line tool similar to curl using Go and Cobra, a CLI library for Go.

I use https://github.com/spf13/cobra religiously for this kind of thing - it handles all the annoying corner cases of parsing flags, and also has an intuitive notion of subcommands (with basic usage/help text generated) for picking which task you want to run with positional arguments.

We recently chose cobra[1] to create a cli application. It comes with so many best practices already packaged like autocompletions, help texts etc. etc.

I looked at the docs: https://cobra.dev/ ... and there are only examples on how to add new flags.

For installing Cobra-CLI you can go to Cobraor run go install github.com/spf13/cobra-cli@latest in the terminal.

In my build phase, I compile the source to create a k3sup binary and I also run the binary to generate shell script completions. Give kudos to this functionality which comes from spf13/cobra Go library for CLIs.

NWA is a command-line tool built on cobra. Here's an overview of NWA's commands:
