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: make_encmake.rb
    path of file: ./repos/ruby-packer/ruby/enc
    
    the code of the file until where you have to start completion: #! ./miniruby

dir = File.expand_path
    
def target_transcoders
  atrans = []
  trans = Dir.open($srcdir+"/trans") {|d|
    d.select {|e|
      if e.chomp!('.trans')
        atrans << e
        true
      elsif e.chomp!('.c')
        true
      end
