Question

I’m trying to use optparse to parse command line arguments. I would like my program to accept arguments like that:

$ ./myscript.rb [options] filename 

I can easily manage the [options] part:

require 'optparse'  options = { :verbose => false, :type => :html }  opts = OptionParser.new do |opts|   opts.on('-v', '--verbose') do     options[:verbose] = true   end   opts.on('-t', '--type', [:html, :css]) do |type|     options[:type] = type   end end opts.parse!(ARGV) 

But how do I get the filename?

I could extract it manually from ARGV, but there has to be a better solution, just can’t figure out how

Answer 1

The ‘parse’ method returns the unprocessed ARGV. So in your example, it will return a one element array with the filename in it.
