You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: base_command.rb
    path of file: ./repos/ruby_jard/lib/ruby_jard/commands
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module RubyJard
  module Commands
    # Base command for all Jard comm
    
      def call(*args)
        setup

        self.opts = slop
        self.args = opts.parse!(args)

        if opts.present?(:help)
          output.puts help
          output.puts "\n"
          void
        else
          process(*normalize_method_args(method(:process), args))
        end
