* | Fix line-prefix display when there's a 'display' string at BOLEli Zaretskii2025-08-231-19/+67
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/xdisp.c (push_it): Reset the 'string_from_prefix_prop_p' flag. (try_window_id): Disable this optimization if the last unchanged at-beg row begins with a display or overlay string and there;s a line/wrap-prefix property on the row. (push_prefix_prop): Accept an additional argument FROM_BUFFER to indicate that the prefix property was found on buffer text underlying a display or overlay property, and set up the position to pop to accordingly. Reset the 'string_from_display_prop_p' flag of the iterator after pushing IT to set up for iterating the prefix string. (get_it_property): Use it->string, not it->object, as indication that prefix property is on a string. (get_line_prefix_it_property): Accept an additional argument: pointer to a flag indicating that the prefix property was found on buffer text underlying a display or overlay property. Callers adjusted. (handle_line_prefix): Use the FROM_BUFFER flag to correctly handle prefix properties on buffer text at the same position as a display string. (Bug#79275)
* | Speed up JSON parsing by not maintaining line and column (bug#79192)Mattias Engdegård2025-08-211-88/+131
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We use the current parsing position instead. The line and column in the error weren't used (nor very accurate to begin with) and the user can easily compute them when needed. The line number calculation is kept just in case but deprecated, for removal in Emacs 32. * src/json.c (struct json_parser, json_parser_init): Update parser state. (json_signal_error): New position computation. (json_skip_whitespace_internal): Remove. (is_json_whitespace): New. (json_skip_whitespace, json_skip_whitespace_if_possible) (json_parse_unicode, json_parse_string, json_parse_number) (json_parse_value): Simplify and rewrite for efficiency. (count_chars, count_newlines) (string_byte_to_pos, string_byte_to_line) (buffer_byte_to_pos, buffer_byte_to_line): New. (Fjson_parse_string, Fjson_parse_buffer): Adapt to new parser state. * test/src/json-tests.el (json-tests--parse-string-error-pos) (json-tests--parse-buffer-error-pos, json-parse-error-position): New. * etc/NEWS: Note deprecation of line and column.

* | Signal end-of-file with more correct dataSpencer Baugh2025-08-191-12/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | end_of_file_error previously always signaled end-of-file with load-true-file-name if that was non-nil (and a string). However, this might be the wrong thing to do; for example, if a file being loaded calls read on a buffer. * src/lread.c (end_of_file_error): <source>: New argument; check it to determine what data to signal with. (bug#68546) (read_char_escape, read_char_literal, read_string_literal) (skip_space_and_comments, read0): Pass source to end_of_file_error.

* | Zero fd_callback_info when deleting an fdSpencer Baugh2025-08-161-12/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | .waiting_thread and .thread could be left set to non-NULL values in a deleted fd_callback_info entry. These would never be cleared by e.g. clear_waiting_thread_info since that only clears fd_callback_info entries up to max_desc. Clear fd_callback_info entirely when deleting an entry. * src/process.c (clear_fd_callback_data): Add. (delete_write_fd, delete_keyboard_wait_descriptor): Call clear_fd_callback_data. (bug#79201) (delete_read_fd): Remove duplicated clearing code. (deactivate_process): Remove duplicate recompute_max_desc.

Also add a mapping to 'treesit-major-mode-remap-alist' for the case when a non-ts mode is installed from an external source to be able to customize it with 'treesit-enabled-modes'.

| | | | | | | | | | | | | | | | | | | | * src/eval.c: new primitive debugger-trap * src/.gdbinit: set breakpoint to Fdebugger_trap * etc/DEBUG: document it. Remove suggestion to use Fredraw_display. This do-nothing primitive gives control to GDB, and for debugging convenience a breakpoint is set by default in .gdbinit.

* | NS: Correct the accessibility role of Emacs windows (bug#77062)Rudolf Adamkovič2025-07-311-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make the accessibility role of Emacs windows to be "standard window" (AXWindow) instead of "text field" (AXTextField). This matches other applications on NS, as can be verified with any accessibility inspector. All widely used NS ports, such as Emacs Plus, have this patch already applied. As for practical impact, this change makes Emacs, for example, work with tiling window managers, such as Yabai, where many users report problems with Emacs specifically, and are instructed to simply avoid the official NS port of GNU Emacs due to this problem. * src/nsterm.m: ([EmacsWindow accessibilityAttributeValue:]): Make the accessibility role of Emacs windows to be "standard window" (AXWindow) instead of "text field" (AXTextField).
* | Refactor reader to use readbuf_t in more placesMattias Engdegård2025-07-301-98/+68
| | | | | | | | | | | | | | | | | | | | Simplify the code by using the already existing dynamic string buffer type. This is a refactoring; performance isn't measurably affected. * src/lread.c (grow_read_buffer): Dissolve into... (readbuf_grow): ...here, simplifying the code. (add_char_to_buffer): Check for growth before adding char, not after. (read_integer, read_string_literal): Use readbuf_t.

| | | | | | | | | | | | | | | | | | | | | | | | These have nothing to do with the Lisp reader at all.

* | Disable Gnulib’s non-Gregorian calendarsPaul Eggert2025-07-291-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prepare for the next Gnulib merge by disabling the optional support for non-Gregorian calendars recently added to Gnulib’s nstrftime module. This would be tricky to integrate with Emacs, as Emacs has its own (much fancier) calendar system, one that at least for the Persian calendar sometimes disagrees with Gnulib’s, and it’s likely not worth the trouble of reconciling the conflicts. * src/conf_post.h (SUPPORT_NON_GREG_CALENDARS_IN_STRFTIME): New macro, defined to false. * admin/merge-gnulib (GNULIB_MODULES): nstrftime → nstrftime-limited. (AVOIDED_MODULES): Add localcharset. Near the end, also remove the files lib/calendar-ethiopian.h, lib/calendar-persian.h, lib/calendar-thai.h, lib/calendars.h.

* | Update Android frame param handlersPo Lu2025-07-271-1/+1

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new 'borders-respect-alpha-background' frame parameter, when set to 't', will make window dividers and internal borders respect the 'alpha-background' frame parameter. This allows transparent gaps between windows. * doc/lispref/frames.texi (Font and Color Parameters): Document the change. * src/frame.c (frame_parm_table, syms_of_frame) (gui_set_borders_respect_alpha_background): * src/frame.h (struct frame): Add frame parameter. * src/androidfns.c (x_create_frame, android_create_tip_frame) (android_frame_parm_handlers): * src/haikufns.c (haiku_create_frame, haiku_create_tip_frame) (haiku_frame_parm_handlers): * src/nsfns.m (ns_frame_parm_handlers, x_create_frame): * src/w32fns.c (x_create_frame, w32_create_tip_frame) (w32_frame_parm_handlers): Add dummy parameters for backends that don't support opacity. * src/pgtkfns.c (pgtk_frame_parm_handlers, x_create_frame) (pgtk_create_tip_frame): * src/pgtkterm.c (pgtk_draw_window_divider): * src/xfns.c (x_create_frame, x_create_tip_frame) (x_frame_parm_handlers) * src/xterm.c (x_draw_window_divider) (x_clear_under_internal_border): Implement parameter on backends that support opacity.

| | | | | | | | | | | | | | * src/callproc.c (init_callproc): Don’t bother testing for the existence of ../src/ and NEWS if installation-directory is non-nil, because in that case we will test for ../etc/NEWS anyway. Simplify by using AUTO_STR.

| | | | | | | | | | | | | | | | | | | | | | | | When PATH is unset or empty, use the system default, to be consistent with GNU/Linux and with POSIX. If there is no system default do not default to "." as that can be dangerous. * src/callproc.c (init_callproc_1, init_callproc): Default PATH to the null pointer, not the empty string. * src/emacs.c (default_PATH): New function.

* | Simplify file end finding in insert-file-contentsPaul Eggert2025-07-231-19/+18
| | | | | | | | | | | | | | * src/fileio.c (Finsert_file_contents): Don’t give up finding the file’s end merely because SEEK_END fails. Try a small test read anyway. This might work in non-POSIX file systems where SEEK_END is not allowed, and trying is easy and simplifies the code.
