    #destination=(destination)   (rw, protected)
  



  

    

Sets the absolute destination value from a relative destination value. It also stores the given and relative destination. Let’s suppose our script is being executed on “dest”, it sets the destination root to “dest”. The destination, given_destination and relative_destination are related in the following way:



inside "bar" do
  empty_directory "baz"
end

destination          #=> dest/bar/baz
relative_destination #=> bar/baz
given_destination    #=> baz

def destination=(destination)
  return unless destination

  @destination = ::File.expand_path(@given_destination, base.destination_root)
  @relative_destination = base.relative_to_original_destination_root(@destination)
end


  








  

    #exists?  ⇒ Boolean  (readonly)
  



  

    

Checks if the destination file already exists.



Returns


Boolean




true if the file exists, false otherwise.

Instance Method Details



  

    #convert_encoded_instructions(filename)   (protected)
  



  

    

Filenames in the encoded form are converted. If you have a file:



%file_name%.rb



It calls #file_name from the base and replaces %-string with the return value (should be String) of #file_name:



user.rb



The method referenced can be either public or private.
