def commit text, insert

  start_offset = Position.to_offset(text, range.start)
  end_offset = Position.to_offset(text, range.ending)
  (start_offset == 0 ? '' : text[0..start_offset-1].to_s) + normalize(insert) + text[end_offset..-1].to_s
end

def initialize range, new_text

Parameters:

  else
    result = commit text, fixed
