Regarding other ports, I've also been pretty happy with https://github.com/nodeca/argparse, which works nicely from Typescript. Looks like it hasn't been updated for a while, but it's not like there's a great deal wrong with it.

https://github.com/p-ranav/argparse is a single-file argparse for Modern C++, which means it's typically straightforward, if baffling in places and a bit annoying to step through in the debugger.

The nice thing about the argparse ports is that provided they take their job seriously, your programs will all end up with a vaguely consistent command line UX in terms of longopt syntax, and, importantly, a --help page.
