I’m looking for a package to implement a CLI in Julia but all I can find is [`ArgParse`](https://argparsejl.readthedocs.io/en/latest/argparse.html), which takes a pretty complicated and old fished approach (based, I assume on the antiquated [Python’s `argparse`](https://docs.python.org/3/library/argparse.html)).
Is there something more usable and modern, like [Python’s `click`](https://click.palletsprojects.com/en/8.0.x/)?
_(I know how this sounds; but painful experience with `argparse` and the contrasting experience of using `click` have done that to me.)_

There is [Comonicon.jl](https://github.com/comonicon/Comonicon.jl) (I have no experience with it though).

That looks promising. It would be great if someone could point me to some meaningful examples. I can’t even find documentation for it, but it sounds great.

Documentation: [https://comonicon.org/stable/](https://comonicon.org/stable/) (I used the “website” entry on the GitHub repo, but would be good to link to it from the README as usual too)

I followed both of those links but found nothing that explained `@cast`.

Greetings to y’all!
As a complete noob to Julia, I was curious myself about creating a CLI for a calendering-app I’m working on. Much to my surprise, I learned that Julia has a few built-in functions along those requirements, documented @ [The Julia REPL · The Julia Language](https://docs.julialang.org/en/v1/stdlib/REPL/#TerminalMenus) … Not exactly a fancy point-and-click feature, but a time-saver nonetheless IMHO.

That’s pretty neat. Not what I’m looking for but cool nonetheless.
