std.getopt is a little clunky, but it is what I would prefer most of the time.
They are basically just different ways to do the same exact thing. So most of the time it is simply a preference thing.

there is also Vladimir Panteleev's  ae.funopt

std.getopt always, also since a few weeks i think that a better version could be done. The expected options are defined in a run-time parameters. This can definitively be some template parameters, which would allow complex static checks and more optimal code.

Now:

    GetOptResult r = getopt(args, "o|option", &o, "p|param", &param);

The future:

    GetOptResult r = getopt!("o|option", o, "p|param", param))(args);

I use std.getopt in my tools. Overall it's pretty good, and the reliability of a package in the standard library has value. That said, I've bumped up against it's limits, and looking at the code, it's not clear to how extend it to more advanced use cases. There may be a case for introducing a next generation package.

Thanks for mentioning this, looks to be just what the doctor ordered.

Coming in from python I've been disappointed by getopt and frustrated by Argon.  This looks like it might fit the bill.  Meta-names for option arguments ( ex: --index=FILE ) are an efficient way to communicate intent to users, nice to see them included.

Thanks,
