readline VS cobra

A readline shell library: https://github.com/reeflective/readline.The `readline` library has been fully rewritten to provide full support for the widespread `.inputrc` init file format (used by bash shells and all programs using the GNU C Readline library). The library has been rewritten into a much more robust codebase with complete test coverage of the core code.

This library wraps the readline library (described below) and leverages cobra commands in order to provide a closed-loop console working with cobra commands out of the box, also providing many comfort-of-life features at minimum cost, like support for oh-my-posh prompt engines, different menus and much more.

Readline (https://github.com/reeflective/readline)

Readline (https://github.com/reeflective/readline) Readline libraries in pure Go already exist, and the chzyer/readline one is widely used. However they might lack some features, or even a full-fledged Emacs/Vim edition mode. Most of them lack many UI features found in common shells. Readline has been written to bring a new shell library with features found in most recent shells, with a simple API for developpers.

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:
