   2
   3         * dispnew.c (direct_output_for_insert): Give up if we are
   4         reordering bidirectional text.
   5
   6         * dispextern.h (IT_STACK_SIZE): Enlarge to 5.
   7
   8         * xdisp.c (display_line): Set row->end and it->start for the next
   9         row to the next character in logical order.  If we are reordering
  10         bidi text, push and pop the iterator before and after momentarily
  11         iterating in logical order.
  12
  13 2009-09-11  Eli Zaretskii  <eliz@gnu.org>
  14
  15         * xdisp.c (set_iterator_to_next, reseat, reseat_1)
  16         (reseat_at_next_visible_line_start): Accept additional argument
  17         force_logical_p; all callers changed.  If force_logical_p is
  18         non-zero, force iteration in buffer's logical order even in bidi
  19         buffers.
  20
  21         * dispnew.c (direct_output_for_insert): Call set_iterator_to_next
  22         with additional argument zero.
  23
  24         * dispextern.h (set_iterator_to_next): Now accepts an additional
  25         argument.
  26
  27 2009-08-29  Eli Zaretskii  <eliz@gnu.org>
  28
  29         * xdisp.c (set_cursor_from_row): Don't assume glyph->charpos
  30         increments linearly.
  31         (try_window_reusing_current_matrix): Don't assume glyph->charpos
  32         increments linearly.
  33
  34 2009-08-28  Eli Zaretskii  <eliz@gnu.org>
  35
  36         * bidi.c <bidi_overriding_paragraph_direction>: Default to L2R,
  37         for now.

  42         (bidi_check_type): New function.
  43         (bidi_cache_iterator_state, bidi_remember_char)
  44         (bidi_resolve_explicit_1, bidi_resolve_explicit)
  45         (bidi_resolve_weak, bidi_resolve_neutral)
  46         (bidi_level_of_next_char): Use it to validate the bidi type
  47         assigned to the iterator.
  48
  49 2009-08-15  Eli Zaretskii  <eliz@gnu.org>
  50

  52
  53         * xdisp.c (set_iterator_to_next): Fix position setting after call
  54         to bidi_get_next_char_visually.
  55
  56 2005-12-03  Eli Zaretskii  <eliz@gnu.org>
  57
  58         * bidi.c: Include stdio.h unconditionally.  Fix and elaborate
  59         commentary.  Add Copyright blurb.
  60
  61 2004-03-08  Kenichi Handa  <handa@m17n.org>
  62
  63         * xdisp.c (reseat_1): Call bidi_init_it with a previous position.
  64
  65         * bidi.c (bidi_init_it): Set bidi_it->ch_len even if POS > 0.
  66

  80         (syms_of_buffer): Declarations of Lisp variables
  81         default-bidi-display-reordering and bidi-display-reordering.

  89
  90         * dispnew.c (direct_output_forward_char): Give up if we need bidi
  91         processing or buffer's direction is right-to-left.
