Re: [gedit-list] Plugin development question

Btw,

I would maybe look into the performance problem. For example, I see
that you use get_iter_at_line with a line index, which could be
potentially very slow. You could replace that by something that moves
the iter to the next line each time, pseudo code would be something
like this:

iter = buffer.get_start_iter()
enditer = buffer.get_end_iter()

while not iter.equal(enditer):
  if not iter.ends_line():
    iter.forward_to_line_end()

  strip_spaces(iter)
  iter.forward_line()
