Yes, it is possible for OptionParser to ignore any unknown options and handle them in a Ruby program at a later time. This can be done by specifying the ignore_invalid_options
option when creating the OptionParser instance. This will cause the parser to ignore any options that it doesn't recognize and store them in the non_options
array. These options can then be processed by the Ruby program using the non_options
array. Here's an example:
require 'optparse'
options = {}
OptionParser.new do |opts|
opts.on("-f", "--file FILE", "Specify file to use") do |file|
options[:file] = file
end
# Ignore any unknown options
opts.ignore_invalid_options = true
end.parse!
puts "File specified: #{options[:file]}"
puts "Unknown options: #{ARGV}"
# Handle unknown options here
In this example, the ignore_invalid_options
option is set to true, indicating that the parser should ignore any unknown options. The non_options
array can be accessed using the ARGV
constant, which contains any arguments that were not parsed as options.
