(choose_minibuf_frame): Remove the emacs_abort for a null minibuffer.

| | | | | | | | | | | | | | | | | | | | * src/image.c (image_get_dimension): New function. (compute_image_size): Use image_get_dimension to set the sizes, and pass in the image struct instead of just the spec. (image_set_transform): (imagemagick_load_image): (svg_load_image): Use the image instead of the spec in compute_image_size. (syms_of_image): Add 'em' as a symbol.

(internal_lisp_condition_case): Implement in interpreter.

| * Add two optional arguments to 'string-width'Eli Zaretskii2021-04-143-28/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/character.c (Fstring_width, lisp_string_width): Accept two optional arguments FROM and TO, to indicate the substring to be considered. (Fstring_width): Add caveats in the doc string about display features ignored by the function. (Bug#47712) * src/character.h (lisp_string_width): Update prototype. * src/editfns.c (styled_format): Adjust call of lisp_string_width to its changed signature. * test/src/character-tests.el (character-test-string-width): New file with tests for 'string-width'. * doc/lispref/display.texi (Size of Displayed Text): Document caveats of using 'string-width'. * etc/NEWS: Announce the change.
| * * 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.
| * Resurrect mouse-highlight of close buttons on tab-barEli Zaretskii2021-04-132-5/+131
| | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/w32term.c (w32_draw_image_relief): Support tab-bar drawing with relief as xterm.c does. * src/xdisp.c (handle_tab_bar_click): Access the mouse-highlight info. Call show_mouse_face to show the button in the pressed or the released state, according to value of DOWN_P. (note_tab_bar_highlight): Function added back. (note_mouse_highlight): Call note_tab_bar_highlight when the mouse pointer is in the tab-bar window. (show_mouse_face): Return immediately if mouse_face_window is not set up in HLINFO. This avoids rare assertion violations.

(init_cmdargs): Put back all the code which was extracted into set_invocation_vars. (load_pdump_find_executable): Make sure the return value has any symlinks in it expanded. (load_pdump): Accept only 2 arguments, not 3. Determine both the file name of the Emacs executable and of the dump file in synchronized manner, so that if we decided to look for the dump file in its hardcoded installation directory, the directory of the Emacs executable will also be where we expect it to be installed. Pass only 2 arguments to pdumper_load. (Bug#47800) (Bug#44128) * src/pdumper.c (dump_do_dump_relocation): Use emacs_execdir instead of Vinvocation_directory to produce absolute file names of *.eln files that are recorded in the pdumper file. Pass the full .eln file name to fixup_eln_load_path. (pdumper_set_emacs_execdir) [HAVE_NATIVE_COMP]: New function. (pdumper_load) [HAVE_NATIVE_COMP]: Call pdumper_set_emacs_execdir. * src/comp.c (fixup_eln_load_path): Use Fsubstring_no_properties instead of Fsubstring. No need to cons a file name, as the caller already did that. Use explicit const string to avoid "magic" values. * lisp/startup.el (normal-top-level): Use expand-file-name instead of concat. Decode comp-eln-load-path and expand-file-name its members.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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)
