Substitution of getopts is possible as follows. Also see OptionParser#getopts.

def getopts(*args)
  ($OPT = ARGV.getopts(*args)).each do |opt, val|
    eval "$OPT_#{opt.gsub(/[^A-Za-z0-9_]/, '_')} = val"
  end
rescue OptionParser::ParseError
end

require 'random/formatter'

Random.alphanumeric     #=> "2BuBuLf3WfSKyQbR"
# or
prng = Random.new
prng.alphanumeric(10) #=> "i6K93NdqiH"
