There really aren't many other good + * options (excuse the pun) for parsing options in a situation like + * this. getopt is kinda braindead, so you end up having to run + * through the options twice, and give each invocation of getopt + * the option string for the other invocation. + * + * You would think that you could just have two groups of options. + * The first group would get parsed by the first invocation of + * getopt, and the second group would get parsed by the second + * invocation of getopt. It doesn't quite work out that way. When + * the first invocation of getopt finishes, it leaves optind pointing + * to the argument _after_ the first argument in the second group. + * So when the second invocation of getopt comes around, it doesn't + * recognize the first argument it gets and then bails out. + * + * A nice alternative would be to have a flag for getopt that says + * "just keep parsing arguments even when you encounter an unknown + * argument", but there isn't one. So there's no real clean way to + * easily parse two sets of arguments without having one invocation + * of getopt know about the other. + * + * Without this hack, the first invocation of getopt would work as + * long as the generic arguments are first, but the second invocation + * (in the subfunction) would fail in one of two ways. In the case + * where you don't set optreset, it would fail because optind may be + * pointing to the argument after the one it should be pointing at. + * In the case where you do set optreset, and reset optind, it would + * fail because getopt would run into the first set of options, which + * it doesn't understand. + * + * All of this would "sort of" work if you could somehow figure out + * whether optind had been incremented one option too far. The + * mechanics of that, however, are more daunting than just giving + * both invocations all of the expect options for either invocation. + * + * Needless to say, I wouldn't mind if someone invented a better + * (non-GPL!) command line parsing interface than getopt. I + * wouldn't mind if someone added more knobs to getopt to make it + * work better. Who knows, I may talk myself into doing it someday, + * if the standards weenies let me.
