argument-parsing helpers c/unix

i know following:

• the princely getopt(3)


• the extended getopt_long


• glibc's parser unix-style justification vectors


• lilliputian digest (or the devout heir )

i'm certain there's some-more i haven't used even listened of; discerning google hunt reveals , , .

personally, i argp best, each way i wrote controlling getopt/getopt_long (beyond certain baseline complexity) converted argp. it's some-more widely accessible popt, some-more comprehensive getopt_long, well-documented, unchanging gnu-style conventions, unequivocally flexible. downside, it's distant easiest (thanks being flexible), formula support definitely plain (as things c).

what use, why?

yes, i meant c rather c++. there ton c++ parsers, nonetheless i don't c++.

john millikin annals popt longer maintained. i list since programs still -- including abiword, rpm, rsync, samba -- notwithstanding gnome's efforts . nonetheless i've total couple glib's justification parser now, too.

for c++ justification parsing, doubt
