* lisp/cus-start.el: Add customization for tab-bar-position.
* src/dispnew.c (syms_of_display): New variable Vtab_bar_position.
(adjust_frame_glyphs_for_window_redisplay): Use it.
src/xdisp.c (face_at_pos): Removed code to that modified
it->start_of_box_run_p and it->face_box_p. This function should not
modify it.
(handle_face_prop): Added code to update it->start_of_box_run_p and
it->face_box_p.
(underlying_face_id): Input IT made CONST.
* src/xdisp.c (append_space_for_newline): Modified to add the space
with the last face also in terminal interface.
(fill_column_indicator_column): Modified to group more conditions.
(extend_face_to_end_of_line): Simplified code in
fill_column_indicator to use the new function.
* src/xdisp.c (extend_face_to_end_of_line): Added a call to
handle_face_prop_general to extend face after EOL according to
parameter :extend in the faces.
* src/xdisp.c (handle_face_prop_general): New function to specialize
handle_face_prop with ATTR_FILTER.
* src/dispextern.h (face_at_buffer_position): Added
LFACE_ATTRIBUTE_INDEX.
* src/xfaces.c (merge_face_ref): Added LFACE_ATTRIBUTE_INDEX to merge
conditionally.
* src/dispextern.h (enum face_underline_type): Add FACE_NO_UNDERLINE = 0.
(struct face): Merge `underline_type` and `underline_p` into `underline`.
Update all the occurrences in src/xdisp.c, src/xfaces.c, and src/xterm.c.
* src/keymap.c (copy_keymap_1, copy_keymap_set_char_table): Ensure
we don't recurse infinitely when using non-sparse keymaps, too.
This change makes this form not segfault:
(let ((map (make-keymap)))
(define-key map " " map)
(copy-keymap map))
* src/frame.c (syms_of_frame): Update doc string and default value of
frame-inhibit-implied-resize in NS to not include 'tab-bar-lines,
and non-toolkit X builds to include 'tab-bar-lines.
* src/keymap.c (copy_keymap_1): Factor out and refuse to recurse
infinitely (bug#7496).
(Fcopy_keymap): ... from here.
(copy_keymap_item): Pass on the depth parameter.
* src/textprop.c (Fadd_face_text_property): We need to be
non-destructive in buffers, too, because face properties may have
been added with `put-text-property' as a list that's been reused.
* src/xdisp.c (syms_of_xdisp) <display-line-numbers-offset>:
New variable to add an offset to absolute line numbers.
(syms_of_xdisp) <display-line-numbers>: Mention it in docstring.
(maybe_produce_line_number): Use it.
* doc/emacs/display.texi (Display Custom): Document it.
* etc/NEWS (value): Announce it.
* lisp/frame.el: Add `display-line-numbers-offset' to list of
variables which should trigger redisplay of the current buffer.
* src/xdisp.c (maybe_produce_line_number): Check beyond_zv
before using a tick face for the line number. Move all face
selection code outside the loop that draws the line number.
* src/textprop.c (add_properties): Take a parameter to say whether
it's allowed to be destructive or not (bug#20153).
(add_text_properties_1): Ditto.
(Fadd_face_text_property): Use this to say that it shouldn't
modify face properties on strings destructively. This avoids
altering the face properties of one string when altering them on a
copy of the string.
* src/xdisp.c (redisplay_internal): Revert the recent change
regarding TTY frames' garbaged flag. It is not needed.
* src/dispnew.c (adjust_frame_glyphs_for_frame_redisplay):
When returning due to mismatch between the desired and actual
dimensions of the glyph matrix, set the frame's garbaged flag
for TTY frames. This avoids crashes when we are later called
from redisplay. Reported by Ergus <spacibba@aol.com>.
* src/xdisp.c (redisplay_internal): Avoid inflooping due to a
frame's garbaged flag being set after update_frame. Reported
by Michael Heerdegen <michael_heerdegen@web.de>.
I had misinterpreted the private email from Ashish Shukla.
* src/fileio.c (Ffile_acl): Fix typo in previous change
by negating the call to acl_errno_valid.
* lisp/faces.el (line-number-major-tick, line-number-minor-tick):
New faces.
* lisp/cus-start.el (display-line-numbers-major-tick)
(display-line-numbers-minor-tick): Add customization info.
* lisp/frame.el: Add `display-line-numbers-major-tick' and
`display-line-numbers-minor-tick' to list of variables which
should trigger redisplay of the current buffer.
* src/xdisp.c (syms_of_xdisp) <display-line-numbers-major-tick>
<display-line-numbers-major-tick>: Defvar new options.
(syms_of_xdisp) <line-number-major-tick, line-number-minor-tick>:
Defsym new faces.
(maybe_produce_line_number): Use new faces for line numbers
that are multiple of `display-line-numbers-major-tick' and
`display-line-numbers-minor-tick'.
* etc/NEWS (value): Announce new feature.
* doc/emacs/display.texi (Display Custom): Describe it. Wording by
Robert Pluim <rpluim@gmail.com>
Problem reported privately for FreeBSD 12 by Ashish Shukla.
* src/fileio.c (Ffile_acl): Treat EINVAL etc. like ENOTSUP if
acl_get_file fails, to port to FreeBSD 12 and other non-GNU
platforms.
This for now doesn't work on GPM.
* src/xdisp.c (display_tab_bar): Make the loop over tab-bar
items more efficient.
(tab_bar_item_info, tool_bar_item_info): Correct data type for
CHARPOS.
(tty_get_tab_bar_item, tty_handle_tab_bar_click): New functions.
(note_mouse_highlight): Handle help-echo of tab-bar tabs on
TTY frames.
* src/w32inevt.c (do_mouse_event): Call
tty_handle_tab_bar_click to process mouse clicks on the tab bar.
* src/termchar.h (tty_handle_tab_bar_click): Add prototype.
* src/w32console.c (w32con_set_terminal_modes): Disable Quick
Edit mode on entry, to make sure mouse events get reported to
us.
* doc/emacs/calendar.texi (Calendar Systems)
* doc/lispref/os.texi (Time Conversion):
Prefer "BC" to "B.C." since the documentation generally uses "BC".
* doc/misc/emacs-mime.texi (time-date):
* lisp/calendar/time-date.el (date-to-day, time-to-days):
In the doc string, state the day origin more clearly, and more
consistently with the rest of the documentation.
* src/timefns.c (Fdecode_time): State the year origin in
the doc string.
* src/xdisp.c (redisplay_internal): Detect when the frame
becomes garbaged inside the call to update_frame, and redraw
the frame in that case. (Bug#37579)
