* Add new Lisp implementation of substitute-command-keysStefan Kangas2020-10-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This is only the first step towards a full Lisp implementation, and does not remove the old C code. On the contrary, it is partly based on using the old C code, which is to be replaced in steps. This also makes it easy to test that it produces the same output as the old. * src/doc.c (Fsubstitute_command_keys_old): Rename from Fsubstitute_command_keys. (Fget_quoting_style): New defun to expose text_quoting_style to Lisp. (syms_of_doc): Expose above symbols. * lisp/help.el (substitute-command-keys): New Lisp version of substitute-command-keys. (Bug#8951) * src/keymap.c (Fdescribe_map_tree): New defun to expose describe_map_tree to Lisp. (syms_of_keymap): New defsubr for Fdescribe_map_tree. * src/keyboard.c (help_echo_substitute_command_keys): * src/doc.c (Fdocumentation, Fdocumentation_property): * src/print.c (print_error_message): * src/syntax.c (Finternal_describe_syntax_value): Fix calls to use new Lisp implementation of substitute-command-keys. * test/src/doc-tests.el: Remove file. * test/lisp/help-tests.el: Add tests for substitute-command-keys copied from above file.
* Handle escaped comment enders correctly in syntax.c, fixing bug #43558Alan Mackenzie2020-09-231-0/+7
| | | | | | | This fixes forward-comment, scan-lists, and parse-partial-sexp. * src/syntax.c (forw_comment): Detect and skip an escaped comment ender (e.g. \*/ in C) when comment-end-can-be-escaped is non-nil.

* | Prefer more inline functions in character.hPaul Eggert2020-04-171-60/+53

* Revert "Move description of value to syntax-ppss function."Lars Ingebrigtsen2019-10-301-1/+19
| | | | | | This reverts commit 305dbc7e2be05748039aacb1a3d697f6f64bed4c. Both of the functions in question are used a lot in the sources, so move it back to the more basic function.
* Move description of value to syntax-ppss function.Lars Ingebrigtsen2019-10-301-19/+1

* Simplify list creation in C codePaul Eggert2019-03-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The main new thing here is that C code can now say ‘list (a, b, c, d, e, f)’ instead of ‘listn (CONSTYPE_HEAP, 6, a, b, c, d, e, f)’, thus relieving callers of the responsibility of counting arguments (plus, the code feels more like Lisp). The old list1 ... list5 functions remain, as they’re probably a bit faster for small lists. * src/alloc.c (cons_listn, pure_listn): New functions. (listn): Omit enum argument. All callers changed to use either new ‘list’ or ‘pure_list’ macros. * src/charset.c (Fdefine_charset_internal): * src/coding.c (detect_coding_system) (Fset_terminal_coding_system_internal): * src/frame.c (frame_size_history_add, adjust_frame_size): * src/gtkutil.c (xg_frame_set_char_size): * src/keyboard.c (command_loop_1): * src/nsfns.m (frame_geometry): * src/widget.c (set_frame_size): * src/xfaces.c (Fcolor_distance): * src/xfns.c (frame_geometry): * src/xterm.c (x_set_window_size_1): * src/xwidget.c (Fxwidget_size_request): Prefer list1i, list2i, etc. to open-coding them. * src/charset.c (Fset_charset_priority): * src/nsterm.m (append2): * src/window.c (window_list): * src/xfaces.c (Fx_list_fonts): Use nconc2 instead of open-coding it. * src/eval.c (eval_sub, backtrace_frame_apply): * src/kqueue.c (kqueue_generate_event): * src/nsterm.m (performDragOperation:): * src/pdumper.c (Fpdumper_stats): * src/w32.c (init_environment): Prefer list1, list2, etc. to open-coding them. * src/font.c (font_list_entities): Parenthesize to avoid expanding new ‘list’ macro. * src/gtkutil.c (GETSETUP): Rename from MAKE_FLOAT_PAGE_SETUP to get lines to fit. Move outside the ‘list’ call, since it’s now a macro. * src/keymap.c (Fmake_keymap): Simplify. * src/lisp.h (list, pure_list): New macros. (list1i): New function.

(update_interval): When moving to an interval's parent, set that parent's ->position field, to maintain the consistency of the tree. * src/intervals.h (struct interval): Amend the comment describing when ->position is valid. * src/pdumper.c: Update the hash associated with struct interval. * src/regex-emacs.c: (re_match_2_internal): Only invoke POINTER_TO_OFFSET on a known character boundary. Only perform arithmetic on character positions, not on byte positions. Correct the argument to an invocation of UPDATE_SYNTAX_TABLE_FORWARD by adding 1 to it (in case wordend:). * src/syntax.c: (update_syntax_table): Remove the now redundant code that set the ->position field of all parents of the interval found by update_interval.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Widen modification counts to at least 64 bits, to make wraparound practically impossible. * doc/lispref/buffers.texi (Buffer Modification): Don’t say the modification-count can wrap around. * src/buffer.c (Frestore_buffer_modified_p, Fbuffer_swap_text) (modify_overlay): * src/insdel.c (insert_1_both, insert_from_string_1) (insert_from_gap, insert_from_buffer_1) (adjust_after_replace, replace_range, replace_range_2) (del_range_2, modify_text): * src/textprop.c (modify_text_properties): Use modiff_incr instead of incrementing directly.

| | | | | | | | | | | | | Most of this change is to boilerplate commentary such as license URLs. This change was prompted by ftp://ftp.gnu.org's going-away party, planned for November. Change these FTP URLs to https://ftp.gnu.org instead. Make similar changes for URLs to other organizations moving away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and fsf.org when this works, as this will further help defend against man-in-the-middle attacks (for this part I omitted the MS-DOS and MS-Windows sources and the test tarballs to keep the workload down). HTTPS is not fully working to lists.gnu.org so I left those URLs alone for now.

| | | | | | | | | | | | | | Problem noted by Eli Zaretskii in: http://lists.gnu.org/archive/html/emacs-devel/2017-01/msg00721.html This patch also fixes some other issues in that report. * src/lisp.h (incr_rarely_quit): Remove. All callers changed to use rarely_quit directly. * src/search.c (freeze_buffer_relocation) (thaw_buffer_relocation): New functions. (looking_at_1, fast_looking_at, search_buffer): Use them to fix bug when quitting when buffers are frozen. * src/sysdep.c (emacs_intr_read): Rename from emacs_nointr_read. All uses changed.
* Revamp quitting and fix infloopsPaul Eggert2017-02-011-40/+72
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes some infinite loops that cannot be quitted out of, e.g., (defun foo () (nth most-positive-fixnum '#1=(1 . #1#))) when byte-compiled and when run under X. See: http://lists.gnu.org/archive/html/emacs-devel/2017-01/msg00577.html This also attempts to keep the performance improvements I recently added, as much as possible under the constraint that the infloops must be caught. In some cases this fixes infloop bugs recently introduced when I removed immediate_quit. * src/alloc.c (Fmake_list): Use rarely_quit, not maybe_quit, for speed in the usual case. * src/bytecode.c (exec_byte_code): * src/editfns.c (Fcompare_buffer_substrings): * src/fns.c (Fnthcdr): * src/syntax.c (scan_words, skip_chars, skip_syntaxes) (Fbackward_prefix_chars): Use rarely_quit so that users can C-g out of long loops. * src/callproc.c (call_process_cleanup, call_process): * src/fileio.c (read_non_regular, Finsert_file_contents): * src/indent.c (compute_motion): * src/syntax.c (scan_words, Fforward_comment): Remove now-unnecessary maybe_quit calls. * src/callproc.c (call_process): * src/doc.c (get_doc_string, Fsnarf_documentation): * src/fileio.c (Fcopy_file, read_non_regular, Finsert_file_contents): * src/lread.c (safe_to_load_version): * src/sysdep.c (system_process_attributes) [GNU_LINUX]: Use emacs_read_quit instead of emacs_read in places where C-g handling is safe. * src/eval.c (maybe_quit): Move comment here from lisp.h. * src/fileio.c (Fcopy_file, e_write): Use emacs_write_quit instead of emacs_write_sig in places where C-g handling is safe. * src/filelock.c (create_lock_file): Use emacs_write, not plain write, as emacs_write no longer has a problem. (read_lock_data): Use emacs_read, not read, as emacs_read no longer has a problem. * src/fns.c (rarely_quit): Move to lisp.h and rename to incr_rarely_quit. All uses changed.. * src/fns.c (Fmemq, Fmemql, Fassq, Frassq, Fplist_put, Fplist_member): * src/indent.c (compute_motion): * src/syntax.c (find_defun_start, back_comment, forw_comment) (Fforward_comment, scan_lists, scan_sexps_forward): Use incr_rarely_quit so that users can C-g out of long loops. * src/fns.c (Fnconc): Move incr_rarely_quit call to within inner loop, so that it catches C-g there too. * src/keyboard.c (tty_read_avail_input): Remove commented-out and now-obsolete code dealing with interrupts. * src/lisp.h (rarely_quit, incr_rarely_quit): New functions, the latter moved here from fns.c and renamed from rarely_quit. (emacs_read_quit, emacs_write_quit): New decls. * src/search.c (find_newline, search_buffer, find_newline1): Add maybe_quit to catch C-g. * src/sysdep.c (get_child_status): Always invoke maybe_quit if interruptible, so that the caller need not bother. (emacs_nointr_read, emacs_read_quit, emacs_write_quit): New functions. (emacs_read): Rewrite in terms of emacs_nointr_read. Do not handle C-g or signals; that is now for emacs_read_quit. (emacs_full_write): Replace PROCESS_SIGNALS two-way arg with INTERRUPTIBLE three-way arg. All uses changed.
* Remove immediate_quit.Paul Eggert2017-02-011-28/+2
| | | | | | | | | The old code that sets and clears immediate_quit was ineffective except when Emacs is running in terminal mode, and has problematic race conditions anyway, so remove it. This will introduce some hangs when Emacs runs in terminal mode, and these hangs should be fixed in followup patches. * src/keyboard.c (immediate_quit): Remove. All uses removed.
* Replace QUIT with maybe_quitPaul Eggert2017-01-251-25/+25
| | | | | | | | There’s no longer need to have QUIT stand for a slug of C statements. Use the more-obvious function-call syntax instead. Also, use true and false when setting immediate_quit. These changes should not affect the generated machine code. * src/lisp.h (QUIT): Remove. All uses replaced by maybe_quit.
