    arguments passed to method with name method_name.

  if ::File.respond_to?(method_name)
    ::File.public_send(method_name, *args, &block)

  end
end

.realpath(path) ⇒ String

On JRuby, File.realpath does not resolve symlinks, so need to drop to Java to get the real path.

Parameters:

  • path (String) —

    a path that may contain '.', '..', or symlinks

Returns:

  • (String) —

    canonical path

Parameters:

  • method_name (Symbol) —

    name of method.
