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: git.rb
    path of file: ./repos/colorls/lib/colorls
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require 'pathname'
require 'set'

module ColorLS
  module Git
    EMPTY_SET = Set.new.freeze
    private_constant :EM
    
    def self.status(repo_path)
      prefix, success = git_prefix(repo_path)

      return unless success

      prefix_path = Pathname.new(prefix)

      git_status = Hash.new { |hash, key| hash[key] = Set.new }
      git_status_default = EMPTY_SET

      git_subdir_status(repo_path) do |mode, file|
        if file == prefix
          git_status_default = Set[mode].freeze
        else
          path = Pathname.new(file).relative_path_from(prefix_path)
          git_status[path.descend.first.cleanpath.to_s].add(mode)
        end
      end
