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

##
#
# Gem::PathSupport facilitates the GEM_HOME and GEM_PATH 
    
  def split_gem_path(gpaths, home)
    # FIX: it should be [home, *path], not [*path, home]

    gem_path = []

    if gpaths
      gem_path = gpaths.split(Gem.path_separator)
      # Handle the path_separator being set to a regexp, which will cause
      # end_with? to error
      if /#{Gem.path_separator}\z/.match?(gpaths)
        gem_path += default_path
      end
