| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * doc/lispref/windows.texi (Vertical Scrolling): Document new `preserve-vscroll-p' parameter of `set-window-vscroll'. * etc/NEWS: Announce new parameter. * lisp/pixel-scroll.el (pixel-scroll-precision-scroll-down-page) (pixel-scroll-precision-scroll-up-page): Use that parameter when setting the vscroll. * src/window.c (window_scroll_pixel_based, Fset_window_vscroll): Adjust for new parameter. * src/window.h (struct window): New flag `preserve_vscroll_p'. * src/xdisp.c (redisplay_window): Preserve the vscroll inside force_start on frozen windows with that flag set. (bug#55312)
| * src/xdisp.c: Use same test in `redisplay_window` and `prepare_menu_bars`Stefan Monnier2022-04-271-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This consolidates the test made in those two functions so as to make sure they agree whether a window needs to be redisplayed. At the same time, change this test so it uses the window's point rather than the buffer's point when comparing to `w->last_point`. * src/xdisp.c (needs_no_redisplay): New function, extracted from `redisplay_window`. (redisplay_window, prepare_menu_bars): Use it. * src/window.c (window_point): New function, extracted from `Fwindow_point`. (Fwindow_point): Use it. * src/window.h (window_point): Declare it.

| | | | | | | | | | * src/window.c (sanitize_window_sizes): Remove; no-longer-used. A previous refactoring moved this to Lisp without removing the C code.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

(Fminibuffer_innermost_command_loop_p): New primitive. (Fabort_minibuffers): Check the command loop level before throwing t to 'exit, and set minibuffer_quit_level too. (read_minibuf): New variable calling_window. Before stacking up minibuffers on the current mini-window, check that the mini-window is not the current one. Do not call choose_minibuf_frame from read_minibuf's unwinding process. Bind calling_frame and calling_window over the recursive edit. Set the new minibuffer's major mode directly. Remove the switching away from the minibuffer after the recursive edit. (get_minibuffer): Record the command loop level in new variable Vcommand_loop_level_list. No longer set the major mode of a returned minibuffer. (minibuf_c_loop_level): New function. (read_minibuf_unwind): New variables calling_frame, calling_window are unbound from the binding stack. Remove old variable `window', which could not be set reliably to the expired mini-window. The expired minibuffer is determined as the nth in the list, rather than the contents of the current or previous mini-window. Switch the current window away from the mini-window here (moved from read_minibuf).

(Minibuffer Commands): Document that exit-minibuffer throws an error when not invoked from the innermost Minibuffer.

(choose_minibuf_frame): check (minibuf > 1) in place of (minibufer > 0) at a particular place. At another place, check that an alleged frame is so and is live. Before selecting a non-miniwindow on a different frame, ensure it really is a different frame. (move_minibuffer_onto_frame): Stack up all recursive minibuffers on the target frame. Check the minibuf_window isn't in the old frame before setting that frame's miniwindow to an inactive minibuffer. (Finnermost_minibuffer_p, Fabort_minibuffers): New primitives.

(read_minibuf): Record the calling frame in a variable, and switch back to it after the recursive edit has terminated normally, using select-frame-set-input-focus.

Some of these changes are to pacify gcc -Wnull-dereference, since GCC is smarter about pointers now that Emacs no longer uses __builtin_assume_aligned; these minor changes should improve code efficiency slightly.

| | | | | | | | | | | | | | * src/lisp.h (vectorlike_headed): Change from struct to union. All uses changed. Since it has only one member, this does not change semantics. This is designed to simplify future changes needed to fix bugs like Bug#29040. All uses changed.
