* * src/minibuf.c (Fread_no_blanks_input): Move to `minibuffer.el`Stefan Monnier2021-04-202-31/+0
| | | | | | | * src/keymap.c (syms_of_keymap): * lisp/minibuffer.el (minibuffer-local-ns-map): Move declaration to initialization. (read-no-blanks-input): Move from `minibuf.c`.
* * src/minibuf.c (read_minibuf): Change multibyte more safelyStefan Monnier2021-04-201-9/+7
| | | | | | | | We used to `bset_enable_multibyte_characters` while the buffer is not empty, putting the buffer temporarily in an inconsistent state. Further simplifications along the way: Prefer re-using local var `histvar` and let `insert` do the unibyte<->multibyte conversion if needed.
* Fix bug #47781: (window-list-1 nil t) wrongly returned nil.Alan Mackenzie2021-04-201-1/+2
| | | | | * src/window.c (candidate_window_p): In the WINDOW_P (all_frames) branch of the conditional, insert "EQ (minibuf, Qt)" in the requisite place.

(read_minibuf, set_minibuffer_mode, read_minibuf_unwind): Use the new DEFSYMs in place of continual interning. (set_minibuffer_mode): Put an active minibuffer into minibuffer-mode rather than fundamental-mode. * doc/emacs/mini.texi (Minibuffer Edit): Mention minibuffer-mode. * doc/lispref/minibuf.texi (Intro to Minibuffers): Add a paragraph about minibuffer-mode. * etc/NEWS (Incompatible Lisp Changes in Emacs 28.1): Add an entry.

* Check minibuffer windows are live windows, rather than assuming itAlan Mackenzie2021-04-161-14/+24
| | | | | | | | | This partly fixes bug #47207. * src/minibuf.c (choose_minibuf_frame, move_minibuffers_onto_frame) (read_minibuf (twice), read_minibuf_unwind): Before using a frame's ->minibuffer_window field, check it is valid with WINDOW_LIVE_P.

* * src/xdisp.c (wset_update_mode_line): Move from `src/window.c`Stefan Monnier2021-04-133-14/+13
| | | | | | | | | | Move that function next to its siblings. Also simplify it, since after careful analysis it is now clear that the frame's title's update is already handled elsewhere (in `prepare_menu_bars` and `redisplay_window`) so we just need to make sure the `redisplay` bit is set. * src/window.c (wset_update_mode_line): Move to `src/xdisp.c`. * src/window.h (wset_update_mode_line): Declare.

* Fix handling of mouse clicks on tab-bar buttonsEli Zaretskii2021-04-111-137/+10
| | | | | | | | | | | | | | | | * src/xdisp.c (note_mouse_highlight): Don't attempt to highlight tab-bar buttons. (note_tab_bar_highlight): Function deleted: it had no effect on display of tab-bar buttons. (tab_bar_item_info): Mention all arguments in the commentary. (get_tab_bar_item): Don't pay attention to mouse-highlight information; instead, compare the button's index with the one recorded in f->last_tab_bar_item. (handle_tab_bar_click): Don't attempt to show tab-bar buttons in pressed or released state: that isn't supported. Determine whether to generate a tab-bar button click based on DOWN_P argument, not on mouse-highlight, which has no effect on tab-bar display. (Bug#47581)
