hook the assing value of options

[edusantana]

    method_option :input_dir, :aliases => '-i', :default => '.'
    method_option :output_dir, :aliases => '-o', :default => '.'
    desc "exec", "to something"
    def exec
      Dir.chdir(options[:input_dir]) do
        # I can't use options[:output_dir] HERE, because it's now relative to input_dir!
      end
    end

I would like to change the value of an option before it's frozen:

    method_option :input_dir, :aliases => '-i', :default => '.'
    method_option :output_dir, :aliases => '-o', :default => '.'
    desc "exec", "to something"
    def exec
      # I can't do this:
      options[:output_dir] = File.absolute_path(options[:output_dir]) (can't do this!)
      # can't modify frozen Thor::CoreExt::HashWithIndifferentAccess (RuntimeError)
      Dir.chdir(options[:input_dir]) do
         ...
      end
    end

Using temp variables should work here right?

    method_option :input_dir, :aliases => '-i', :default => '.'
    method_option :output_dir, :aliases => '-o', :default => '.'
    desc "exec", "to something"
    def exec
      output_dir = File.absolute_path(options[:output_dir])
      Dir.chdir(options[:input_dir]) do
         ...
      end
    end
