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: version.rb
    path of file: ./repos/vagrant-libvirt/lib/vagrant-libvirt
    
    the code of the file until where you have to start completion: # frozen_string_literal: 
    
    def self.get_version
      if File.exist?(VERSION_FILE)
        # built gem
        version = File.read(VERSION_FILE)
      elsif self.inside_git_repository
        # local repo
        git_version = `git describe --tags`
        version = self.version_from_describe(git_version)
      elsif !GIT_ARCHIVE_VERSION.start_with?('$Format')
        # archive - format string replaced during export
        hash, refs = GIT_ARCHIVE_VERSION.split(' ', 2)

        tag = refs.split(',').select { |ref| ref.strip.start_with?("tag:") }.first
        if tag != nil
          # tagged
          version = tag.strip.split(' ').last
        else
          version = ""
          # arbitrary branch/commit
          Dir.mktmpdir do |dir|
            stdout_and_stderr, status = Open3.capture2e("git -C #{dir} clone --bare #{HOMEPAGE}")
            raise "failed to clone original to resolve version: #{stdout_and_stderr}" unless status.success?

            stdout_and_stderr, status = Open3.capture2e("git --git-dir=#{dir}/vagrant-libvirt.git describe --tags #{hash}")
            raise "failed to determine version for #{hash}: #{stdout_and_stderr}" unless status.success?

            version = version_from_describe(stdout_and_stderr)
          end

          # in this case write the version file to avoid cloning a second time
          File.write(VERSION_FILE, version)
        end
