def rebuild_symlink(target_file,new_file)
  if File.symlink?(new_file)
    File.unlink(new_file)
  end
  File.symlink(target_file, new_file)
end

#remove_and_copy(source, destination) ⇒ Object

Remove a file and copy a new file over. If we just copy source to destination and destination exists and is a directory, then the src is put in the destination, as opposed to overwriting it. For this reason, we delete destination first.

Parameters:

  • source (String) —

    the source file.

  • destination (String) —

    the destination file.

  cp_r source, destination
end

#write_erb_template(erb_file, released_file, opts = {}) ⇒ Object

Create a destination file by filtering a source file through ERB.

Parameters:

  • erb_file (String) —

    the file to be filtered.

  • released_file (String) —

    the result filename.

  • opts (Hash) (defaults to: {}) —

    the options.

Options Hash (opts):

  • :chmod (String) —

    The file mode.
