From fe0066f50fdafe0d93b523ee34420324f4bead0a Mon Sep 17 00:00:00 2001 From: "Richard M. Stallman" Date: Fri, 2 Jan 1998 21:43:42 +0000 Subject: [PATCH] (current_column_1, Fmove_to_column): Update call to CHAR_HEAD_P. (indented_beyond_p): Take POS in bytes and chars. Callers changed. (pos_tab_indent): Function moved to xdisp.c. (Fcurrent_indentation): Use scan_newline and SET_PT_BOTH. (indented_beyond_p, current_column_1): Likewise. (vmotion, compute_motion): Set up bytepos value to return it. (current_column): Handle bytepos and charpos. (position_indentation): Take bytepos as arg, and scan with it. Calls changed. (Fmove_to_column): Scan with bytepos and charpos. (pos_tab_offset): Use bytepos to do FETCH_BYTE. (skip_invisible): Don't worry about position in middle of character. --- src/indent.c | 269 ++++++++++++++++++++++++++++++--------------------- 1 file changed, 161 insertions(+), 108 deletions(-) diff --git a/src/indent.c b/src/indent.c index b4592a2dddf..cf8e361a00c 100644 --- a/src/indent.c +++ b/src/indent.c @@ -53,6 +53,7 @@ int last_known_column_point; int last_known_column_modified; static int current_column_1 (); +static int position_indentation (); /* Cache of beginning of line found by the last call of current_column. */ @@ -243,6 +244,7 @@ skip_invisible (pos, next_boundary_p, to, window) proplimit = overlay_limit; end = XFASTINT (Fnext_single_property_change (position, Qinvisible, buffer, proplimit)); +#if 0 /* Don't put the boundary in the middle of multibyte form if there is no actual property change. */ if (end == pos + 100 @@ -250,6 +252,7 @@ skip_invisible (pos, next_boundary_p, to, window) && end < ZV) while (pos < end && !CHAR_HEAD_P (POS_ADDR (end))) end--; +#endif *next_boundary_p = end; } /* if the `invisible' property is set, we can skip to @@ -317,7 +320,7 @@ current_column () counting width.
