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: fixture.rb
    path of file: ./repos/ruby/spec/mspec/lib/mspec/helpers
    
    the code of the file until where you have to start completion: # Returns the name of a fixture file by adjoining the directory
# of the +file+ argument with "fixtures
    
def fixture(file, *args)
  path = File.dirname(file)
  path = path[0..-7] if path[-7..-1] == "/shared"
  fixtures = path[-9..-1] == "/fixtures" ? "" : "fixtures"
  if File.respond_to?(:realpath)
    path = File.realpath(path)
  else
    path = File.expand_path(path)
  end
