Question

I need to invoke getoptlong multiple times, but after the first time ARGV is empty.

Answer 1

Capture the args before the first call, put them back when you’re done. Sounds like you’re doing something kind of weird, though.

Edit: (expanded)

There’s a lot of copying and pasting in here. I consider that helping with clarity:

require 'getoptlong'  storage = ARGV.clone  opts = GetoptLong.new(   ['--help', '-h', GetoptLong::NO_ARGUMENT ],   [ '--repeat', '-n', GetoptLong::REQUIRED_ARGUMENT ],   [ '--name', GetoptLong::OPTIONAL_ARGUMENT ] )  puts 'Before: #{ARGV.inspect}' opts.each { |opt, arg| puts 'Parsed #{opt} = #{arg}' } puts 'After: #{ARGV.inspect}'  # Copy storage.each {|x| ARGV << x }  opts = GetoptLong.new(   ['--help', '-h', GetoptLong::NO_ARGUMENT ],   [ '--repeat', '-n', GetoptLong::REQUIRED_ARGUMENT ],   [ '--name', GetoptLong::OPTIONAL_ARGUMENT ] )  puts 'Before 2: #{ARGV.inspect}' opts.each { |opt, arg| puts 'Parsed #{opt} = #{arg}' } puts 'After 2: #{ARGV.inspect}'
