* Eliminate some GCC warningsMattias Engdegård2021-06-161-2/+3
| | | | | | | | | | * src/doprnt.c (exprintf, evxprintf): * src/lisp.h (exprintf, evxprintf): Don't use a pointer-to-const type for the `nonheapbuf` argument: although it is never dereferenced, GCC will warn when passing a pointer to uninitialised memory otherwise. * src/fns.c (sort_vector_copy, realize_face, realize_gui_face) (realize_tty_face): Use the same signatures in the prototypes as in the actual function definitions.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This happened with minibuffer-follows-selected-frame set to t. * doc/emacs/mini.texi (Basic Minibuffer): State where a command's action takes place when a minibuffer's frame has been deleted. * lisp/window.el (window--before-delete-windows, record-window-buffer): Take into account that minibuffers are now recorded on w->prev_buffers field. * src/fns.c (merge_c): New version of `merge' taking a C function, rather than a Lisp function as the comparison function. * src/frame.c (do_switch_frame): Pass arguments sf and for_deletion to move_minibuffers_onnto_frame. * src/lisp.h (top level): Declare merge_c and move_minibuffers_onto_selected_frame. * src/minibuf.c (MB_frame): New Lisp_Object recording the minibuffer's frame. (choose_minibuf_frame): Remove all code except that which sets minibuf_window to the current frame's minibuffer. (minibuffer_ent_greater): New comparison function, passed to merge_c. (zip_minibuffer_stacks): New function. (move_minibuffers_onto_frame): Renamed from `move_minibuffer_onto_frame' given two arguments, the old frame and for_deletion, and simplified. Minibuffers are now stacked in the mini-window's ->prev_buffers field. (read_minibuf): Several detailed amendments. (exp_MB_frame): New Lisp_Object, the expired minibuffer's frame. (read_minibuf_unwind): Search for the expired minibuffer's frame, rather than taking it from (unreliable) variables. Switch temporarily to this frame for tidying up operations. (minibuffer_unwind): New function which pops a stacked minibuffer. (syms_of_minibuf): Call staticpro for the two new Lisp variables. * src/window.c (Fset_window_configuration): Don't record minibuffers with record-window-buffer. * src/xdisp.c (gui_consider_frame_title): Remove redundant Fselect_window, which caused an unwanted frame switch. Amend the arguments to format_mode_line_unwind_data to match.

| | | | | | | | | | * lisp/cus-start.el: Add use-short-answers. * lisp/emacs-lisp/map-ynp.el (read-answer): Handle use-short-answers. (read-answer-short): Add use-short-answers to docstring. * src/fns.c (Fyes_or_no_p): Call y-or-n-p if use_short_answers is true. (syms_of_fns): Add DEFVAR_BOOL use-short-answers (bug#46594).
* Fix count-lines problem in non-ASCII buffersLars Ingebrigtsen2021-02-091-1/+1
| | | | | * src/fns.c (Fline_number_at_pos): Get the correct start position in non-ASCII buffers (bug#22763).
* Allow Fline_number_at_pos being called with a markerLars Ingebrigtsen2021-02-071-1/+3
| | | | | * src/fns.c (Fline_number_at_pos): Also allow being called with a marker (since the Lisp function allowed that).
* Move line-number-at-pos to CLars Ingebrigtsen2021-02-071-9/+22
| | | | | | | | | | | | | * doc/lispref/positions.texi (Text Lines): Revert previous change. * lisp/simple.el (line-number-at-pos): Remove definition. * lisp/simple.el (count-lines): Revert back to using `forward-line', because there seems to be a disagreement on how lines should be counted in a region... * src/fns.c (Fline_number_at_pos): Rename from Fline_number_at_position and adjust parameter list.
* Add a new function 'line-number-at-position'Lars Ingebrigtsen2021-02-071-0/+18
| | | | | | | | | * doc/lispref/positions.texi (Text Lines): Document it. * lisp/simple.el (count-lines): Use it. (line-number-at-pos): Ditto. * src/fns.c (Fline_number_at_position): New function (bug#22763).
* * src/fns.c (hash_string): Fix bug#46111Stefan Monnier2021-01-281-19/+15
| | | | | Use `memcpy` instead of an unaligned memory access. On x86 at least, GCC turns this `memcpy` into a single `mov`, so it's about as fast.
* Add a new function 'buffer-line-statistics'Lars Ingebrigtsen2021-01-121-0/+85
| | | | * src/fns.c (Fbuffer_line_statistics): New function.

* More string-search optimisationsMattias Engdegård2020-11-191-8/+15
| | | | | | | | | | | All-ASCII strings cannot have substrings with non-ASCII characters in them; use this fact to avoid searching entirely. * src/fns.c (Fstring_search): For multibyte non-ASCII needle and unibyte haystack, don't check if the haystack is all-ASCII; it's a waste of time. For multibyte non-ASCII needle and multibyte all-ASCII haystack, fail immediately. * test/src/fns-tests.el (string-search): Add more test cases.
* eql doc improvementsPaul Eggert2020-10-131-0/+1
| | | | | | | * doc/lispref/numbers.texi (Comparison of Numbers): Copy some useful text from eql help string. * src/fns.c (Feql): In doc string, say that eql also compares integers by value.
* Use the full name of the null byte/character, not its abbreviationAndreas Schwab2020-10-051-1/+1
| | | | | | | | | | | | | | | | | | | | | * lisp/subr.el (inhibit-nul-byte-detection): Make it an obsolete alias. * src/coding.c (setup_coding_system): Use original name. (detect_coding): Rename nul_byte_found => null_byte_found. (detect_coding_system): Use original name. Rename nul_byte_found => null_byte_found. (Fdefine_coding_system_internal): Use original name.

* Minor string-search optimisations (bug#43598)Mattias Engdegård2020-09-271-32/+27
| | | | | | | * src/fns.c (Fstring_search): Perform cheap all-ASCII checks before more expensive ones. Use a faster loop when searching for non-ASCII non-raw bytes. * test/src/fns-tests.el (string-search): Add more test cases.
* Fix searching for multibyte needles in unibyte haystacksLars Ingebrigtsen2020-09-271-4/+41
| | | | | * src/fns.c (Fstring_search): Make this work better when searching unibyte haystacks for multibyte needles (bug#43598).
* Add tiny optimization for string-searchLars Ingebrigtsen2020-09-271-1/+7
| | | | | * src/fns.c (Fstring_search): Add tiny optimization for needles that are longer than the haystack (bug#43598).

* Fix recently-introduced Fdelete bugPaul Eggert2020-08-151-25/+4
| | | | | | | | | Problem reported by Pip Cet in: https://lists.gnu.org/r/emacs-devel/2020-08/msg00444.html * src/fns.c (Fdelete): Fix correctness bug via a simpler (though more memory-intensive) approach. It’s probably not worth optimizing the memory usage yere. * test/src/fns-tests.el (test-vector-delete): Add test for the bug.
* Minimize ‘equal’ calls in (delete x vector)Paul Eggert2020-08-151-9/+29
| | | | | | | | | * src/fns.c (Fdelete): When deleting from a vector, call Fequal only once per vector element. This is faster when Fequal is slow, and avoids the need to preinitialize the vector result. Finish when the result is exhausted, not when the input is exhausted; the two are equivalent but the former may be faster. * test/src/fns-tests.el (test-vector-delete): New test.
* Fdelete speed tweak for stringsPaul Eggert2020-08-151-2/+5
| | | | | * src/fns.c (Fdelete): Hoist FIXNUMP out of a loop, and turn it into CHARACTERP.
* Fix GC bugs related to uninitialized vectorsPaul Eggert2020-08-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | Avoid problems if GC occurs while initializing a vector. Problem with Fdelete reported by Pip Cet in: https://lists.gnu.org/r/emacs-devel/2020-08/msg00313.html I looked for similar problems elsewhere and found quite a few. * src/coding.c (make_subsidiaries): * src/composite.c (syms_of_composite): * src/font.c (build_style_table, Ffont_get_glyphs): * src/nsselect.m (clean_local_selection_data): * src/nsxwidget.m (js_to_lisp): * src/syntax.c (init_syntax_once): * src/window.c (Fcurrent_window_configuration): * src/xselect.c (selection_data_to_lisp_data) (clean_local_selection_data): Use make_nil_vector instead of make_uninit_vector. * src/fns.c (Fdelete): * src/xwidget.c (webkit_js_to_lisp): Use allocate_nil_vector instead of allocate_vector. * src/search.c (Fnewline_cache_check): Use make_vector instead of make_uninit_vector.
