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: cat.rb
    path of file: ./repos/CocoaPods/lib/cocoapods/command/spec
    
    the code of the file until where you have to start completion: module Pod
  class Command
    class Spec < Command
      class Cat < Spec
        self.summary = 'Prints a spec
    
        def run
          query = @use_regex ? @query : Regexp.escape(@query)
          filepath = if @show_all
                       specs = get_path_of_spec(query, @show_all).split(/\n/)
                       index = UI.choose_from_array(specs, "Which spec would you like to print [1-#{specs.count}]? ")
                       specs[index]
                     else
                       get_path_of_spec(query, @version)
                     end
