From 3e1451520bdae2a79247347e66724306692533f6 Mon Sep 17 00:00:00 2001 From: Chong Yidong Date: Fri, 1 Sep 2006 13:28:13 +0000 Subject: * buffer.h (struct buffer_text): New field chars_modiff. (CHARS_MODIFF, BUF_CHARS_MODIFF): New macros. * buffer.c (Fbuffer_chars_modified_tick): New function returning value of BUF_CHARS_MODIFF. (syms_of_buffer): Defsubr it. (Fget_buffer_create): Initialize BUF_CHARS_MODIFF. * insdel.c (modify_region): New argument preserve_chars_modiff. Set CHARS_MODIFF to MODIFF provided preserve_chars_modiff is zero. (insert_1_both, insert_from_string_1, insert_from_buffer_1) (adjust_after_replace, adjust_after_replace_noundo) (replace_range, replace_range_2, del_range_2): Reset CHARS_MODIFF. * lisp.h (modify_region): Add fourth argument in extern. * casefiddle.c (casify_region): Call modify_region with fourth argument zero to assert that CHARS_MODIFF is updated. * editfns.c (Fsubst_char_in_region, Ftranslate_region_internal) (Ftranspose_regions): Likewise. * textprop.c (Fadd_text_properties, Fset_text_properties) (Fremove_text_properties, Fremove_list_of_text_properties): Call modify_region with fourth argument 1 to avoid that CHARS_MODIFF is updated. --- src/buffer.h | 10 ++++++++++ 1 file changed, 10 insertions(+) (limited to 'src/buffer.h') diff --git a/src/buffer.h b/src/buffer.h index efe0252453a..a5f8a6a4070 100644 --- a/src/buffer.h +++ b/src/buffer.h @@ -82,6 +82,9 @@ Boston, MA 02110-1301, USA. */ /* Modification count. */ #define MODIFF (current_buffer->text->modiff) +/* Character modification count. */ +#define CHARS_MODIFF (current_buffer->text->chars_modiff) + /* Overlay modification count. */ #define OVERLAY_MODIFF (current_buffer->text->overlay_modiff) @@ -147,6 +150,9 @@ Boston, MA 02110-1301, USA. */ /* Modification count. */ #define BUF_MODIFF(buf) ((buf)->text->modiff) +/* Character modification count. */ +#define BUF_CHARS_MODIFF(buf) ((buf)->text->chars_modiff) + /* Modification count as of last visit or save. */ #define BUF_SAVE_MODIFF(buf) ((buf)->text->save_modiff) @@ -406,6 +412,10 @@ struct buffer_text for this buffer.
