@dpecos if you opt for the jvm approach, take a look at #picocli

#picocli: I used an `IExecutionStrategy` to require a positional parameter only for some commands

I was looking at `@ArgGroup` first, but that would not have had helped me here, teaching the simple program to download all registered devices from #Garmin, without a #GDPR archive

Btw, is Remko Popma here? Can't find him…

@cwensel we recently used #picocli and I can't recommend it enough!

Started working on this new cli app using #picocli. It seems easier to work with than #ApacheCommonsCLI. Will share more about my cli app once I make enough progress!

For example: I wanna write a easy-to-write & read #commandline / #cli option-parser for #cpp where you dont need to know how exactly #getopt works and what global variables & states it has.

One of the best other libraries out there for such stuff is #picocli ( https://picocli.info/ ). So naturally I wanna build something similar in #cpp .

But theres soooo many problems: bc c++ dosnt has real generics, only templates, there is ofc no typeerasure, meaning that I constantly need to pass around all template params. Wich means that theres no easy way having a type `Option<Cmd>` (options for a specific command), inside a list like `std::vector`! Even tho the storage space of a pointer is the same: 8 bytes, and thanks to virtual methods calling the right methods isnt a problem either!
