class Erubi::Engine

Must be called with a string, cannot be called with nil (Rails's subclass depends on it).
Add raw text to the template. Modifies argument if argument is mutable as a memory optimization.

def add_text(text)
  return if text.empty?
  text = _dup_string_if_frozen(text)
  text.gsub!(/['\\]/, '\\\\\&')
  with_buffer{@src << " << '" << text << @text_end}
end
