ruby idioms controlling command-line options

i'm perplexing collect adult flush porting medium-sized (non-oo) perl program. personal idioms set options this:

use getopt::std;
our $opt_v;  # verbose
getopts('v');
# after ...
$opt_v && imitation "something interesting\n";

in perl, i kind courage teeth let $opt_v (effectively) global.

in ruby,the more-or-less accurate homogeneous

require 'optparse'
    opts.on("-v", "--[no-]verbose", trueclass, "run verbosely") {
        |$opt_verbose|
    }
    opts.parse!
end

where $opt_verbose tellurian classes access. carrying classes know tellurian flags seems ... er ... wrong. what's oo-idiomatic proceed doing this?

• let sure slight take caring option-related things have classes only relapse things it decides understanding with?


• have classes exercise discretionary intrepidity (e.g., know verbose) set mode around an attr_writer arrange thing?

updated: interjection answers suggesting optparse, nonetheless i should have clearer it's how slight command-line options i'm seeking about, nonetheless some-more charge between command-line options effectively set tellurian way state classes should ideally individualist arrange thing.
