6 * Introduction | |
7 ============== | |
8 | |
9 This file presents some general information about XEmacs. It is primarily | |
10 about the evolution of XEmacs and its release history. | |
11 | |
12 There are five sections. | |
13 | |
14 Introduction................(this section) provides an introduction | |
15 | |
16 Using Outline Mode..........briefly explains how to use outline mode | |
17 | |
18 XEmacs Release Notes........detailed changes to this release | |
19 | |
20 Future Plans for XEmacs.....what's next | |
21 | |
22 The History of XEmacs.......some historical notes | |
23 | |
24 A Long List of Packages.....all the stuff in XEmacs | |
25 | |
26 What Changed................between versions and also FSF GNU Emacs | |
27 | |
28 New users should look at the next section on "Using Outline Mode". | |
29 You will be more efficient when you can navigate quickly through this | |
30 file. Users who want to know which capabilities have been introduced | |
31 in this release should look at the "XEmacs Release Notes." Users | |
32 interested in some of the details of how XEmacs differs from GNU Emacs | |
33 should read the section "What Changed?". | |
34 | |
35 N.B. The term "FSF GNU Emacs" refers to any release of Emacs | |
36 Version 19 from the Free Software Foundation's GNU Project. (We do | |
37 not say just "GNU Emacs" because Richard M. Stallman ["RMS"] | |
38 thinks that this term is too generic; although we sometimes say | |
39 e.g. "GNU Emacs 19.30" to refer to a specific version of FSF GNU | |
40 Emacs. The term "XEmacs" refers to this program or to its | |
41 predecessors "Era", "Epoch", and "Lucid Emacs". The predecessor | |
42 of all these program is called "Emacs 18". When no particular | |
43 version is implied, "Emacs" will be used. | |
44 | |
45 | |
46 * Using Outline Mode | |
47 ==================== | |
48 | |
49 This file is in outline mode, a major mode for viewing (or editing) | |
50 outlines. It allows you to make parts of the text temporarily invisible so | |
51 that you can see just the overall structure of the outline. | |
52 | |
53 There are two ways of using outline mode: with keys or with menus. Using | |
54 outline mode with menus is the simplest and is just as effective as using | |
55 keystrokes. There are menus for outline mode on the menubar as well as in | |
56 popup menus activated by pressing mouse button 3. | |
57 | |
58 Try the following to help you read this file. | |
59 | |
60 C-c C-q This hides everything but the very top level headings | |
61 You can then move to an interesting section | |
62 C-c TAB This shows subheadings (if any) of current heading. | |
63 C-c C-s Show _all_ the text and headings under current heading | |
64 C-c C-d Hide _all_ the text and headings under current heading | |
65 | |
66 It's then easy to navigate through the file alternating between | |
67 showing, C-C C-s, and hiding, C-c C-d, the text. Also, use the "Show" | |
68 and "Hide" menus displayed to get access to the same commands. | |
69 | |
70 You may at any time press `C-h m' to get a listing of the outline mode key | |
71 bindings. | |
72 | |

242 | |
243 ** Major Differences Between 19.14 and 19.15 | |
244 ============================================ | |
245 | |
246 Many bugs have been fixed. An effort has been made to eradicate all | |
247 XEmacs crashes, although we are not quite done yet. The overall | |
248 quality of XEmacs should be higher than any previous release. XEmacs | |
249 now compiles with nary a warning with some compilers. | |
250 | |
251 User visible changes: | |
252 | |
253 -- EFS replaces ange-ftp for remote file manipulation capability. | |
254 | |
255 -- TM (Tools for Mime) now comes with XEmacs. This provides MIME | |
256 (Multi-purpose Internet Multi-media Extensions?) support for Mail | |
257 and News. The primary author is Morioka Tomohiko. | |
258 | |
259 -- There is a new way to customize faces and (some) variables. | |
260 Try it with `M-x customize RET', or from the Options->Customize menu. | |
261 Documented in <URL:info:custom>. | |
262 | |
263 -- The AUC TeX environment for editing and running TeX is now bundled. | |
264 (Per Abrahamsen.) | |
265 Enable with (require 'tex-site) in your .emacs file. | |
266 Documented in <URL:info:auctex>. | |
267 | |
268 -- New user option `init-face-from-resources'. | |
269 If you don't set faces with X resources, you can speed up the | |
270 initialization of new faces by setting this to nil. | |
271 | |
272 -- `column.el' removed, use `column-number-mode' instead. | |
273 | |
274 -- Command line processing should work much better now - no more order | |
275 dependencies. | |
276 | |
277 -- html mode now defaults to using HTML-3.2 | |
278 | |
279 -- VM now has a native MIME mode | |
280 | |
281 -- The traditional time.el package now has optional modeline graphics | |
282 | |
283 -- The XEmacs Logo has been changed courtesy of Jens Lautenbacher | |
284 | |
285 -- Default background changed to gray80 | |
286 | |
287 -- The XEmacs build procedure has been changed to make it easier than | |
288 ever to include new packages to be dumped with the binary | |
289 | |
290 -- cc-mode is no longer auto-loaded. (require 'cc-mode) is now needed | |
291 before you customize cc-mode in your .emacs. | |
292 | |
293 -- blink-cursor-mode is somewhat more useable now that the cursor | |
294 stops blinking during keyboard activity. | |
295 | |
296 -- Dired is now part of efs and went from version 6.X to 7.9. | |
297 Keybindings have been synced with FSF Emacs, there are more menus and | |
298 items in menus are sometimes grouped differently. Any personnal | |
299 customization to dired will probably have to be checked. | |
300 | |
301 If you are a 19.14 user and use its dired a lot, expect to get mad at | |
302 'c', 'r' and '^' keybindings." | |
303 | |
304 | |

488 ------------ | |
489 | |
490 -- New `widget' library for inserting UI components in buffers. | |
491 Documented in <URL:info:widget>. | |
492 | |
493 -- New `custom' library for declaring user options and faces. | |
494 Documented in <URL:info:custom>. | |
495 | |
496 -- New function `make-empty-face'. | |
497 Like `make-face', but doesn't query the resource database. | |
498 | |
499 -- New function x-keysym-on-keyboard-p helps determine keyboard | |
500 characteristics for key rebinding: | |
501 | |
502 x-keysym-on-keyboard-p: (KEYSYM &optional DEVICE) | |
503 -- a built-in function. | |
504 Return true if KEYSYM names a key on the keyboard of DEVICE. | |
505 More precisely, return true if pressing a physical key | |
506 on the keyboard of DEVICE without any modifier keys generates KEYSYM. | |
507 Valid keysyms are listed in the files /usr/include/X11/keysymdef.h and in | |
508 /usr/lib/X11/XKeysymDB, or whatever the equivalents are on your system. | |
509 | |
510 -- Usage of keysyms of the form kp_0 is deprecated and one should use | |
511 the Emacs compatible kp-0 instead. | |
512 | |
513 | |
514 -- preceding-char and following-char have been obsoleted. Use the | |
515 much safer and correct functions char-after and char-before instead. | |
516 | |
517 -- Many symbols present for compatibility with GNU Emacs no longer | |
518 generate bytecompiler warning messages | |
519 | |
520 -- Installed info files are now compressed (support courtesy of Joseph J Nuspl) | |

525 -- OffiX drag-and-drop support added | |
526 | |
527 -- lots of syncing with 19.34 elisp files, most by Steven Baur | |
528 | |
529 -- M-: (eval-expression) is now enabled by default since it is much | |
530 more difficult to type. | |

536 * Future Plans for XEmacs | |
537 ========================== | |
538 | |
539 This is the end of the line for XEmacs v19. No new development is planned | |
540 on this source tree. XEmacs 20.1 will contain the functionality in 19.15, | |
541 and development will continue with XEmacs 20.2. The major new `feature' | |
542 planned in 20.2 will be the introduction of separable packages and the | |
543 capability to download and use an XEmacs lite distribution. | |
544 | |
545 * The History of XEmacs | |
546 ======================= | |
547 | |
548 This product is an extension of GNU Emacs, previously known to some as | |
549 "Lucid Emacs" or "ERA". It was initially based on an early version of Emacs | |
550 Version 19 from the Free Software Foundation and has since been kept | |
551 up-to-date with recent versions of that product. It stems from a | |
552 collaboration of Lucid, Inc. with SunSoft DevPro (a division of Sun | |
553 Microsystems, Inc.; formerly called SunPro) and the University of Illinois. | |
554 | |
555 NOTE: Lucid, Inc. is currently out of business but development on XEmacs | |
556 continues strong. Recently, Amdahl Corporation and INS Engineering have | |
557 both contributed significantly to the development of XEmacs. | |
558 | |
559 | |
560 * A Long List of Packages | |
561 ======================= | |
562 | |
563 This section gives a detailed list of packages included with XEmacs. | |
564 It's long! Of particular interest are: games, gnus, modes, packages, | |
565 and utils. | |
566 | |
567 ** auctex - Super TeX | |
568 *** auctex/auc-old.el | |
569 This file contains an alternative keymapping, compatible with | |
570 older versions of AUC TeX. You are strongly suggested to try the | |
571 new keyboard layout, as we would like this file to go away | |
572 eventually. | |
573 *** auctex/bib-cite.el | |
574 Commentary: | |
575 | |
576 This package is used in various TeX modes to display or edit references | |
577 associated with \cite commands, or matching \ref and \label commands. | |
578 *** auctex/font-latex.el | |
579 Commentary: | |
580 *** auctex/style/german.el | |
581 Commentary: | |
582 | |
583 `german.sty' use `"' to give next character an umlaut. | |
584 *** auctex/style/harvard.el | |
585 Commentary: | |
586 | |
587 Harvard citation style is from Peter Williams available on the CTAN | |
588 servers | |
589 *** auctex/style/plfonts.el | |
590 Commentary: | |
591 | |
592 `plfonts.sty' use `"' to make next character Polish. | |
593 `plfonts.sty' <C> L. Holenderski, IIUW, lhol@mimuw.edu.pl | |
594 *** auctex/style/plhb.el | |
595 Commentary: | |
596 | |
597 `plhb.sty' use `"' to make next character Polish. | |
598 `plhb.sty' <C> J. S. Bie\'n, IIUW, jsbien@mimuw.edu.pl | |
599 | |
600 | |
601 ** bytecomp - Byte compile Emacs Lisp files | |
602 *** bytecomp/byte-optimize.el | |
603 Commentary: | |
604 | |
605 ======================================================================== | |
606 "No matter how hard you try, you can't make a racehorse out of a pig. | |
607 You can, however, make a faster pig." | |
608 | |
609 Or, to put it another way, the emacs byte compiler is a VW Bug. This code | |
610 makes it be a VW Bug with fuel injection and a turbocharger... You're | |
611 still not going to make it go faster than 70 mph, but it might be easier | |
612 to get it there. | |
613 | |
614 *** bytecomp/bytecomp-runtime.el | |
615 Commentary: | |
616 | |
617 interface to selectively inlining functions. | |
618 This only happens when source-code optimization is turned on. | |
619 *** bytecomp/bytecomp.el | |
620 Commentary: | |
621 | |
622 The Emacs Lisp byte compiler. This crunches lisp source into a sort | |
623 of p-code which takes up less space and can be interpreted faster. | |
624 The user entry points are byte-compile-file and byte-recompile-directory. | |
625 *** bytecomp/disass.el | |
626 Commentary: | |
627 | |
628 The single entry point, `disassemble', disassembles a code object generated | |
629 by the Emacs Lisp byte-compiler. This doesn't invert the compilation | |
630 operation, not by a long shot, but it's useful for debugging. | |
631 | |
632 ** calendar - Calendars, diaries and appointments | |
633 *** calendar/calendar.el | |
634 Commentary: | |
635 | |
636 This collection of functions implements a calendar window. It | |
637 generates a calendar for the current month, together with the previous | |
638 and coming months, or for any other three-month period. The calendar | |
639 can be scrolled forward and backward in the window to show months in | |
640 the past or future; the cursor can move forward and backward by days, | |
641 weeks, or months, making it possible, for instance, to jump to the | |
642 date a specified number of days, weeks, or months from the date under | |
643 the cursor. The user can display a list of holidays and other notable | |
644 days for the period shown; the notable days can be marked on the | |
645 calendar, if desired. The user can also specify that dates having | |
646 corresponding diary entries (in a file that the user specifies) be | |
647 marked; the diary entries for any date can be viewed in a separate | |
648 window. The diary and the notable days can be viewed independently of | |
649 the calendar. Dates can be translated from the (usual) Gregorian | |
650 calendar to the day of the year/days remaining in year, to the ISO | |
651 commercial calendar, to the Julian (old style) calendar, to the Hebrew | |
652 calendar, to the Islamic calendar, to the French Revolutionary calendar, | |
653 to the Mayan calendar, and to the astronomical (Julian) day number. | |
654 When floating point is available, times of sunrise/sunset can be displayed, | |
655 as can the phases of the moon. Appointment notification for diary entries | |
656 is available. | |
657 *** calendar/cal-dst.el | |
658 Commentary: | |
659 | |
660 This collection of functions implements the features of calendar.el and | |
661 holiday.el that deal with daylight savings time. | |
662 *** calendar/cal-french.el | |
663 Commentary: | |
664 | |
665 This collection of functions implements the features of calendar.el and | |
666 diary.el that deal with the French Revolutionary calendar. | |
667 *** calendar/cal-mayan.el | |
668 Commentary: | |
669 | |
670 This collection of functions implements the features of calendar.el and | |
671 diary.el that deal with the Mayan calendar. It was written jointly by | |
672 *** calendar/cal-x.el | |
673 Commentary: | |
674 | |
675 This collection of functions implements dedicated frames in x-windows for | |
676 calendar.el. | |
677 *** calendar/cal-xemacs.el | |
678 Commentary: | |
679 | |
680 This collection of functions implements menu bar and popup menu support for | |
681 calendar.el. | |
682 *** calendar/diary-ins.el | |
683 Commentary: | |
684 | |
685 This collection of functions implements the diary insertion features as | |
686 described in calendar.el. | |
687 *** calendar/solar.el | |
688 Commentary: | |
689 | |
690 This collection of functions implements the features of calendar.el, | |
691 diary.el, and holiday.el that deal with times of day, sunrise/sunset, and | |
692 eqinoxes/solstices. | |
693 | |
694 ** cl - Common Lisp compatibility with Emacs Lisp | |
695 *** cl/cl-compat.el | |
696 Commentary: | |
697 | |
698 These are extensions to Emacs Lisp that provide a degree of | |
699 Common Lisp compatibility, beyond what is already built-in | |
700 in Emacs Lisp. | |
701 | |
702 ** comint - For running shells, telnet, rsh, gdb, dbx under Emacs | |
703 *** comint/comint-xemacs.el | |
704 Commentary: | |
705 | |
706 Declare customizable faces for comint outside the main code so it can | |
707 be dumped with XEmacs. | |
708 *** comint/comint.el | |
709 Commentary: | |
710 | |
711 This file defines a general command-interpreter-in-a-buffer package | |
712 (comint mode). The idea is that you can build specific process-in-a-buffer | |
713 modes on top of comint mode -- e.g., lisp, shell, scheme, T, soar, .... | |
714 This way, all these specific packages share a common base functionality, | |
715 and a common set of bindings, which makes them easier to use (and | |
716 saves code, implementation time, etc., etc.). | |
717 | |
718 Several packages are already defined using comint mode: | |
719 - shell.el defines a shell-in-a-buffer mode. | |
720 - cmulisp.el defines a simple lisp-in-a-buffer mode. | |
721 | |
722 - The file cmuscheme.el defines a scheme-in-a-buffer mode. | |
723 - The file tea.el tunes scheme and inferior-scheme modes for T. | |
724 - The file soar.el tunes lisp and inferior-lisp modes for Soar. | |
725 - cmutex.el defines tex and latex modes that invoke tex, latex, bibtex, | |
726 previewers, and printers from within emacs. | |
727 - background.el allows csh-like job control inside emacs. | |
728 *** comint/gdb.el | |
729 Commentary: | |
730 | |
731 A facility is provided for the simultaneous display of the source code | |
732 in one window, while using gdb to step through a function in the | |
733 other. A small arrow in the source window, indicates the current | |
734 line. | |
735 *** comint/gud.el | |
736 Commentary: | |
737 *** comint/history.el | |
738 Commentary: | |
739 | |
740 suggested generic history stuff -- tale | |
741 | |
742 This is intended to provided easy access to a list of elements | |
743 being kept as a history ring. | |
744 *** comint/inf-lisp.el | |
745 Commentary: | |
746 | |
747 This file defines a a lisp-in-a-buffer package (inferior-lisp | |
748 mode) built on top of comint mode. This version is more | |
749 featureful, robust, and uniform than the Emacs 18 version. The | |
750 key bindings are also more compatible with the bindings of Hemlock | |
751 and Zwei (the Lisp Machine emacs). | |
752 *** comint/kermit.el | |
753 Commentary: | |
754 | |
755 I'm not sure, but I think somebody asked about running kermit under shell | |
756 mode a while ago. Anyway, here is some code that I find useful. The result | |
757 is that I can log onto machines with primitive operating systems (VMS and | |
758 ATT system V :-), and still have the features of shell-mode available for | |
759 command history, etc. It's also handy to be able to run a file transfer in | |
760 an emacs window. The transfer is in the "background", but you can also | |
761 monitor or stop it easily. | |
762 *** comint/rlogin.el | |
763 Commentary: | |
764 | |
765 Support for remote logins using `rlogin'. | |
766 This program is layered on top of shell.el; the code here only accounts | |
767 for the variations needed to handle a remote process, e.g. directory | |
768 tracking and the sending of some special characters. | |
769 *** comint/shell.el | |
770 Commentary: | |
771 | |
772 This file defines a a shell-in-a-buffer package (shell mode) built | |
773 on top of comint mode. This is actually cmushell with things | |
774 renamed to replace its counterpart in Emacs 18. cmushell is more | |
775 featureful, robust, and uniform than the Emacs 18 version. | |
776 *** comint/telnet.el | |
777 Commentary: | |
778 | |
779 This mode is intended to be used for telnet or rsh to a remode host; | |
780 `telnet' and `rsh' are the two entry points. Multiple telnet or rsh | |
781 sessions are supported. | |
782 | |
783 ** custom - Allow's user to customize Emacs | |
784 *** custom/custom.el | |
785 Commentary: | |
786 | |
787 This file only contain the code needed to declare and initialize | |
788 user options. The code to customize options is autoloaded from | |
789 `cus-edit.el'. | |
790 | |
791 The code implementing face declarations is in `cus-face.el' | |
792 | |
793 ** edebug - Emacs Lisp debugger | |
794 *** edebug/cl-read.el | |
795 Commentary: | |
796 | |
797 Please send bugs and comments to the author. | |
798 | |
799 This package replaces the standard Emacs Lisp reader (implemented | |
800 as a set of built-in Lisp function in C) by a flexible and | |
801 customizable Common Lisp like one (implemented entirely in Emacs | |
802 Lisp). During reading of Emacs Lisp source files, it is about 40% | |
803 slower than the built-in reader, but there is no difference in | |
804 loading byte compiled files - they dont contain any syntactic sugar | |
805 and are loaded with the built in subroutine `load'. | |
806 | |
807 ** ediff - Compare and merge files with graphical difference display | |
808 *** ediff/ediff.el | |
809 Commentary: | |
810 | |
811 Never read that diff output again! | |
812 Apply patch interactively! | |
813 Merge with ease! | |
814 | |
815 This package provides a convenient way of simultaneous browsing through | |
816 the differences between a pair (or a triple) of files or buffers. The | |
817 files being compared, file-A, file-B, and file-C (if applicable) are | |
818 shown in separate windows (side by side, one above the another, or in | |
819 separate frames), and the differences are highlighted as you step | |
820 through them. You can also copy difference regions from one buffer to | |
821 another (and recover old differences if you change your mind). | |
822 | |
823 Ediff also supports merging operations on files and buffers, including | |
824 merging using ancestor versions. Both comparison and merging operations can | |
825 be performed on directories, i.e., by pairwise comparison of files in those | |
826 directories. | |
827 | |
828 ** efs - Remote file access (replaces ange-ftp) | |
829 See online manual. | |
830 | |
831 ** electric - The "electric" commands; these implement temporary | |
832 windows for help, list-buffers, etc. | |
833 | |
834 *** electric/ehelp.el | |
835 Commentary: | |
836 | |
837 This package provides a pre-packaged `Electric Help Mode' for | |
838 browsing on-line help screens. There is one entry point, | |
839 `with-electric-help'; all you have to give it is a no-argument | |
840 function that generates the actual text of the help into the current | |
841 buffer. | |
842 | |
843 ** emulators - Various emulations: mocklisp, teco, TPU/EDT, WordStar | |
844 *** emulators/mlconvert.el | |
845 Commentary: | |
846 | |
847 This package converts Mocklisp code written under a Gosling or UniPress | |
848 Emacs for use with GNU Emacs. The translated code will require runtime | |
849 support from the mlsupport.el equivalent. | |
850 *** emulators/mlsupport.el | |
851 Commentary: | |
852 | |
853 This package provides equivalents of certain primitives from Gosling | |
854 Emacs (including the commercial UniPress versions). These have an | |
855 ml- prefix to distinguish them from native GNU Emacs functions with | |
856 similar names. The package mlconvert.el translates Mocklisp code | |
857 to use these names. | |
858 *** emulators/teco.el | |
859 Commentary: | |
860 | |
861 This code has been tested some, but no doubt contains a zillion bugs. | |
862 You have been warned. | |
863 | |
864 Written by Dale R. Worley based on a C implementation by Matt Fichtenbaum. | |
865 Please send comments, bug fixes, enhancements, etc. to drw@math.mit.edu. | |
866 *** emulators/tpu-edt.el | |
867 Commentary: | |
868 | |
869 %% TPU-edt -- Emacs emulating TPU emulating EDT | |
870 | |
871 %% Introduction | |
872 | |
873 TPU-edt emulates the popular DEC VMS editor EDT (actually, it emulates | |
874 DEC TPU's EDT emulation, hence the name TPU-edt). | |
875 *** emulators/tpu-extras.el | |
876 Commentary: | |
877 | |
878 Use the functions defined here to customize TPU-edt to your tastes by | |
879 setting scroll margins and/or turning on free cursor mode. Here's an | |
880 example for your .emacs file. | |
881 *** emulators/ws-mode.el | |
882 Commentary: | |
883 | |
884 This emulates WordStar, with a major mode. | |
885 | |
886 ** energize - Interface to now-defunct Lucid's C/C++ integrated | |
887 environment XEmacs (nee Lucid Emacs) saw birth explicitly to serve | |
888 Energize. | |
889 | |
890 ** eos - SPARCworks | |
891 | |
892 ** eterm - Full terminal emulation under Emacs | |
893 *** eterm/term.el | |
894 Commentary: | |
895 | |
896 This file defines a general command-interpreter-in-a-buffer package | |
897 (term mode). The idea is that you can build specific process-in-a-buffer | |
898 modes on top of term mode -- e.g., lisp, shell, scheme, T, soar, .... | |
899 This way, all these specific packages share a common base functionality, | |
900 and a common set of bindings, which makes them easier to use (and | |
901 saves code, implementation time, etc., etc.). | |
902 *** eterm/tgud.el | |
903 Commentary: | |
904 | |
905 The ancestral gdb.el was by W. Schelter <wfs@rascal.ics.utexas.edu> | |
906 It was later rewritten by rms. Some ideas were due to Masanobu. | |
907 Grand Unification (sdb/dbx support) by Eric S. Raymond <esr@thyrsus.com> | |
908 The overloading code was then rewritten by Barry Warsaw <bwarsaw@cen.com>, | |
909 who also hacked the mode to use comint.el. Shane Hartman <shane@spr.com> | |
910 added support for xdb (HPUX debugger). Rick Sladkey <jrs@world.std.com> | |
911 wrote the GDB command completion code. Dave Love <d.love@dl.ac.uk> | |
912 added the IRIX kluge and re-implemented the Mips-ish variant. | |
913 Then hacked by Per Bothner <bothner@cygnus.com> to use term.el. | |
914 *** eterm/tshell.el | |
915 Commentary: | |
916 | |
917 This file defines a a shell-in-a-buffer package (shell mode) built | |
918 on top of term mode. This is actually cmushell with things | |
919 renamed to replace its counterpart in Emacs 18. cmushell is more | |
920 featureful, robust, and uniform than the Emacs 18 version. | |
921 | |
922 ** games - blackbox, mines, decipher, doctor, ... | |
923 *** games/blackbox.el | |
924 Commentary: | |
925 | |
926 The object of the game is to find four hidden balls by shooting rays | |
927 into the black box. There are four possibilities: 1) the ray will | |
928 pass thru the box undisturbed, 2) it will hit a ball and be absorbed, | |
929 3) it will be deflected and exit the box, or 4) be deflected immediately, | |
930 not even being allowed entry into the box. | |
931 *** games/conx.el | |
932 Commentary: | |
933 | |
934 conx.el: Yet Another Dissociator. | |
935 | |
936 Select a buffer with a lot of text in it. Say M-x conx-buffer | |
937 or M-x conx-region. Repeat on as many other bodies of text as | |
938 you like. | |
939 | |
940 M-x conx will use the word-frequency tree the above generated | |
941 to produce random sentences in a popped-up buffer. It will pause | |
942 at the end of each paragraph for two seconds; type ^G to stop it. | |
943 *** games/cookie1.el | |
944 Commentary: | |
945 | |
946 Support for random cookie fetches from phrase files, used for such | |
947 critical applications as emulating Zippy the Pinhead and confounding | |
948 the NSA Trunk Trawler. | |
949 *** games/decipher.el | |
950 Commentary: | |
951 | |
952 This package is designed to help you crack simple substitution | |
953 ciphers where one letter stands for another. It works for ciphers | |
954 with or without word divisions. (You must set the variable | |
955 decipher-ignore-spaces for ciphers without word divisions.) | |
956 *** games/dissociate.el | |
957 Commentary: | |
958 | |
959 The single entry point, `dissociated-press', applies a travesty | |
960 generator to the current buffer. The results can be quite amusing. | |
961 *** games/doctor.el | |
962 Commentary: | |
963 | |
964 The single entry point `doctor', simulates a Rogerian analyst using | |
965 phrase-production techniques similar to the classic ELIZA demonstration | |
966 of pseudo-AI. | |
967 *** games/flame.el | |
968 Commentary: | |
969 | |
970 "Flame" program. This has a chequered past. | |
971 *** games/gomoku.el | |
972 Gomoku is a game played between two players on a rectangular board. Each | |
973 player, in turn, marks a free square of its choice. The winner is the first | |
974 one to mark five contiguous squares in any direction (horizontally, | |
975 vertically or diagonally). | |
976 | |
977 *** games/hanoi.el | |
978 Commentary: | |
979 | |
980 Solves the Towers of Hanoi puzzle while-U-wait. | |
981 | |
982 The puzzle: Start with N rings, decreasing in sizes from bottom to | |
983 top, stacked around a post. There are two other posts. Your mission, | |
984 should you choose to accept it, is to shift the pile, stacked in its | |
985 original order, to another post. | |
986 *** games/life.el | |
987 Commentary: | |
988 | |
989 A demonstrator for John Horton Conway's "Life" cellular automaton | |
990 in Emacs Lisp. Picks a random one of a set of interesting Life | |
991 patterns and evolves it according to the familiar rules. | |
992 *** games/mine.el | |
993 Commentary: | |

995 The object of this classical game is to locate the hidden mines. | |
996 To do this, you hit the squares on the game board that do not | |
997 contain mines, and you mark the squares that do contain mines. | |

1001 When this package is loaded, `M-x mpuz' generates a random multiplication | |
1002 puzzle. This is a multiplication example in which each digit has been | |
1003 consistently replaced with some letter. Your job is to reconstruct | |
1004 the original digits. Type `?' while the mode is active for detailed help. | |

1006 Commentary: | |
1007 | |
1008 Just before sending mail, do M-x spook. | |
1009 A number of phrases will be inserted into your buffer, to help | |
1010 give your message that extra bit of attractiveness for automated | |
1011 keyword scanners. | |
1012 *** games/studly.el | |
1013 Commentary: | |
1014 | |
1015 Functions to studlycapsify a region, word, or buffer. Possibly the | |
1016 esoteric significance of studlycapsification escapes you; that is, | |
1017 you suffer from autostudlycapsifibogotification. Too bad. | |

1030 Commentary: | |
1031 This file provides access to sound effects in Gnus. | |
1032 Prerelease: This file is partially stripped to support earcons.el | |
1033 You can safely ignore most of it until Red Gnus. **Evil Laugh** | |

1035 Commentary: | |
1036 *** gnus/gnus-undo.el | |
1037 Commentary: | |
1038 | |
1039 This package allows arbitrary undoing in Gnus buffers. As all the | |
1040 Gnus buffers aren't very text-oriented (what is in the buffers is | |
1041 just some random representation of the actual data), normal Emacs | |
1042 undoing doesn't work at all for Gnus. | |
1043 *** gnus/mailheader.el | |
1044 Commentary: | |
1045 | |
1046 This package provides an abstraction to RFC822-style messages, used in | |
1047 mail news, and some other systems. The simple syntactic rules for such | |
1048 headers, such as quoting and line folding, are routinely reimplemented | |
1049 in many individual packages. This package removes the need for this | |
1050 redundancy by representing message headers as association lists, | |
1051 offering functions to extract the set of headers from a message, to | |
1052 parse individual headers, to merge sets of headers, and to format a set | |
1053 of headers. | |
1054 *** gnus/message.el | |
1055 Commentary: | |
1056 | |
1057 This mode provides mail-sending facilities from within Emacs. It | |
1058 consists mainly of large chunks of code from the sendmail.el, | |
1059 gnus-msg.el and rnewspost.el files. | |
1060 *** gnus/nnheader.el | |
1061 Commentary: | |
1062 | |
1063 These macros may look very much like the ones in GNUS 4.1. They | |
1064 are, in a way, but you should note that the indices they use have | |
1065 been changed from the internal GNUS format to the NOV format. The | |
1066 makes it possible to read headers from XOVER much faster. | |

1080 Function `iso-accents-mode' activates a minor mode in which | |
1081 typewriter "dead keys" are emulated. The purpose of this emulation | |
1082 is to provide a simple means for inserting accented characters | |
1083 according to the ISO-8859-1 character set. | |
1084 *** iso/iso-ascii.el | |
1085 Commentary: | |
1086 | |

1152 *** modes/cc-compat.el | |
1153 Commentary: | |
1154 | |
1155 Boring old c-mode.el (BOCM) is confusion and brain melt. cc-mode.el | |
1156 is clarity of thought and purity of chi. If you are still unwilling | |
1157 to accept enlightenment, this might help, or it may prolong your | |
1158 agony. | |
1159 *** modes/cc-guess.el | |
1160 Commentary: | |
1161 | |
1162 This file contains routines that help guess the cc-mode style in a | |
1163 particular region of C, C++, or Objective-C code. It is provided | |
1164 for example and experimentation only. It is not supported in | |
1165 anyway. Some folks have asked for a style guesser and the best way | |
1166 to show my thoughts on the subject is with this sample code. Feel | |
1167 free to improve upon it in anyway you'd like. Please send me the | |
1168 results. Note that style guessing is lossy! | |
1169 *** modes/cc-lobotomy.el | |
1170 Commentary: | |
1171 | |
1172 Every effort has been made to improve the performance of | |
1173 cc-mode. However, due to the nature of the C, C++, and Objective-C | |
1174 language definitions, a trade-off is often required between | |
1175 accuracy of construct recognition and speed. I believe it is always | |
1176 best to be correct, and that the mode is currently fast enough for | |
1177 most normal usage. Others disagree. I have no intention of | |
1178 including these hacks in the main distribution. When cc-mode | |
1179 version 5 comes out, it will include a rewritten indentation engine | |
1180 so that performance will be greatly improved automatically. This | |
1181 was not included in this release of version 4 so that Emacs 18 | |
1182 could still be supported. Note that this implies that cc-mode | |
1183 version 5 will *not* work on Emacs 18! | |
1184 *** modes/cc-mode.el | |
1185 Commentary: | |
1186 | |
1187 This package provides modes in GNU Emacs for editing C, C++, | |
1188 Objective-C, and Java code. It is intended to be a replacement for | |
1189 c-mode.el (a.k.a. BOCM -- Boring Old C-Mode), c++-mode.el, | |
1190 cplus-md.el, and cplus-md1.el, all of which are in some way | |
1191 ancestors of this file. A number of important improvements have | |
1192 been made, briefly: complete K&R C, ANSI C, `ARM' C++, Objective-C, | |
1193 and Java support with consistent indentation across all modes, more | |
1194 intuitive indentation controlling variables, compatibility across | |
1195 all known Emacsen, nice new features, and tons of bug fixes. This | |
1196 package is called "CC Mode" to distinguish it from its ancestors, | |
1197 but there is no cc-mode command. Usage and programming details are | |
1198 contained in an accompanying texinfo manual. | |
1199 *** modes/cl-indent.el | |
1200 Commentary: | |
1201 | |

1211 #! line at the beginning of the file, if the file does not already | |
1212 have one. | |
1213 | |
1214 *** modes/f90.el | |
1215 Commentary: | |
1216 | |
1217 Smart mode for editing F90 programs in FREE FORMAT. | |
1218 Knows about continuation lines, named structured statements, and other | |
1219 new features in F90 including HPF (High Performance Fortran) structures. | |
1220 The basic feature is to provide an accurate indentation of F90 programs. | |
1221 In addition, there are many more features like automatic matching of all | |
1222 end statements, an auto-fill function to break long lines, a join-lines | |
1223 function which joins continued lines etc etc. | |
1224 To facilitate typing, a fairly complete list of abbreviations is provided. | |
1225 For example, `i is short-hand for integer (if abbrev-mode is on). | |
1226 | |
1227 *** modes/follow.el | |
1228 Commentary: | |
1229 | |
1230 `Follow mode' is a minor mode for Emacs 19 and XEmacs which | |
1231 combines windows into one tall virtual window. | |
1232 | |
1233 The feeling of a "virtual window" has been accomplished by the use | |
1234 of two major techniques: | |
1235 | |
1236 * The windows always displays adjacent sections of the buffer. | |
1237 This means that whenever one window is moved, all the | |
1238 others will follow. (Hence the name Follow Mode.) | |
1239 | |
1240 * Should the point (cursor) end up outside a window, another | |
1241 window displaying that point is selected, if possible. This | |
1242 makes it possible to walk between windows using normal cursor | |
1243 movement commands. | |
1244 *** modes/fortran.el | |
1245 Commentary: | |
1246 | |
1247 Fortran mode has been upgraded and is now maintained by Stephen A. Wood | |
1248 (saw@cebaf.gov). It now will use either fixed format continuation line | |
1249 markers (character in 6th column), or tab format continuation line style | |
1250 (digit after a TAB character.) A auto-fill mode has been added to | |
1251 automatically wrap fortran lines that get too long. | |

1257 *** modes/hideif.el | |
1258 Commentary: | |
1259 | |
1260 Hide-ifdef suppresses the display of code that the preprocessor wouldn't | |
1261 pass through. The support of constant expressions in #if lines is | |
1262 limited to identifiers, parens, and the operators: &&, ||, !, and | |
1263 "defined". Please extend this. | |
1264 *** modes/hideshow.el | |
1265 Commentary: | |
1266 | |
1267 This file provides `hs-minor-mode'. When active, six commands: | |
1268 hs-{hide,show}-{all,block}, hs-show-region and hs-minor-mode | |
1269 are available. They implement block hiding and showing. Blocks are | |
1270 defined in mode-specific way. In c-mode or c++-mode, they are simply | |
1271 curly braces, while in lisp-ish modes they are parens. Multi-line | |
1272 comments (c-mode) can also be hidden. The command M-x hs-minor-mode | |
1273 toggles the minor mode or sets it (similar to outline minor mode). | |
1274 See documentation for each command for more info. | |

1287 fashion as other programming language modes. Invoke describe-mode | |
1288 for more information. | |
1289 *** modes/lisp-mnt.el | |
1290 Commentary: | |
1291 | |
1292 This minor mode adds some services to Emacs-Lisp editing mode. | |
1293 | |
1294 First, it knows about the header conventions for library packages. | |
1295 One entry point supports generating synopses from a library directory. | |
1296 Another can be used to check for missing headers in library files. | |
1297 *** modes/lisp-mode.el | |

1322 | |
1323 This package is a major mode for editing nroff source code. It knows | |
1324 about various nroff constructs, ms, mm, and me macros, and will fill | |
1325 and indent paragraphs properly in their presence. It also includes | |
1326 a command to count text lines (excluding nroff constructs), a command | |
1327 to center a line, and movement commands that know how to skip macros. | |
1328 *** modes/old-c-mode.el | |
1329 Commentary: | |
1330 | |
1331 A smart editing mode for C code. It knows a lot about C syntax and tries | |

1379 Commentary: | |
1380 | |
1381 Adapted from Lisp mode by Bill Rozas, jinx@prep. | |
1382 Initially a query replace of Lisp mode, except for the indentation | |
1383 of special forms. Probably the code should be merged at some point | |
1384 so that there is sharing between both libraries. | |

1469 Commentary: | |
1470 | |
1471 The ideas for this package were derived from the C code in | |
1472 src/keymap.c and elsewhere. The functions in this file should | |
1473 always be byte-compiled for speed. Someone should rewrite this in | |
1474 C (as part of src/keymap.c) for speed. | |

1484 | |
1485 The following defines an association list for text to be | |
1486 automatically inserted when a new file is created, and a function | |
1487 which automatically inserts these files; the idea is to insert | |
1488 default text much as the mode is automatically set using | |
1489 auto-mode-alist. | |

1494 this mode moves the mouse pointer - either just a little out of | |
1495 the way, or all the way to the corner of the frame. | |

1508 buffers from a list summarizing their state. A good way to browse | |
1509 any special or scratch buffers you have loaded, since you can't find | |

1513 Commentary: | |
1514 | |
1515 This really has nothing to do with list-command-history per se, but | |
1516 its a nice alternative to C-x ESC ESC (repeat-complex-command) and | |
1517 functions as a lister if given no pattern. It's not important | |

1571 Commentary: | |
1572 | |
1573 This package implements a major mode for editing binary files. It uses | |
1574 a program called hexl, supplied with the GNU Emacs distribution, that | |
1575 can filter a binary into an editable format or from the format back into | |
1576 binary. For full instructions, invoke `hexl-mode' on an empty buffer and | |
1577 do `M-x describe-mode'. | |
1578 *** packages/hyper-apropos.el | |
1579 Commentary: | |
1580 | |
1581 Rather than run apropos and print all the documentation at once, | |

1583 get the details for symbols as you need them. | |

1585 Commentary: | |
1586 | |

1598 | |
1599 This package implements low-level support for reading, writing, | |
1600 and loading compressed files. It hooks into the low-level file | |
1601 I/O functions (including write-region and insert-file-contents) so | |
1602 that they automatically compress or uncompress a file if the file | |
1603 appears to need it (based on the extension of the file name). | |
1604 Packages like Rmail, VM, GNUS, and Info should be able to work | |
1605 with compressed files without modification. | |
1606 *** packages/lazy-lock.el | |
1607 Commentary: | |
1608 | |
1609 Purpose: | |
1610 | |
1611 To make visiting buffers in `font-lock-mode' faster by making fontification | |
1612 be demand-driven and stealthy. | |
1613 Fontification only occurs when, and where, necessary. | |

1636 Commentary: | |
1637 | |
1638 Note: Metamail does not have all options which is compatible with | |

1640 hack the environment variables. In addition, there is no way to | |
1641 display all header fields without extra informative body messages | |
1642 which are suppressed by "-q" option. | |

1660 | |
1661 Purpose of this package: | |

1667 Commentary: | |
1668 | |
1669 This package provides printing of Emacs buffers on PostScript | |
1670 printers; the buffer's bold and italic text attributes are | |
1671 preserved in the printer output. Ps-print is intended for use with | |
1672 Emacs 19 or Lucid Emacs, together with a fontifying package such as | |
1673 font-lock or hilit. | |
1674 *** packages/rcompile.el | |
1675 Commentary: | |
1676 | |
1677 This package is for running a remote compilation and using emacs to parse | |
1678 the error messages. It works by rsh'ing the compilation to a remote host | |
1679 and parsing the output. If the file visited at the time remote-compile was | |
1680 called was loaded remotely (ange-ftp), the host and user name are obtained | |
1681 by the calling ange-ftp-ftp-name on the current directory. In this case the | |
1682 next-error command will also ange-ftp the files over. This is achieved | |
1683 automatically because the compilation-parse-errors function uses | |
1684 default-directory to build it's file names. If however the file visited was | |
1685 loaded locally, remote-compile prompts for a host and user and assumes the | |
1686 files mounted locally (otherwise, how was the visited file loaded). | |

1698 Commentary: | |
1699 | |
1700 The purpose of this library is to handle command line arguments | |
1701 when you resume an existing Emacs job. | |
1702 | |
1703 You can't get the benefit of this library by using the `emacs' command, | |
1704 since that always starts a new Emacs job. Instead you must use a | |
1705 command called `edit' which knows how to resume an existing Emacs job | |
1706 if you have one, or start a new Emacs job if you don't have one. | |
1707 | |
1708 To define the `edit' command, run the script etc/emacs.csh (if you use CSH), | |
1709 or etc/emacs.bash if you use BASH. You would normally do this in your | |
1710 login script. | |

1716 (even during a different Emacs session) automatically moves point | |
1717 to the saved position, when the file is first found. Uses the | |
1718 value of buffer-local variable save-place to determine whether to | |
1719 save position or not. | |

1747 If you put a time stamp template anywhere in the first 8 lines of a file, | |
1748 it can be updated every time you save the file. See the top of | |
1749 time-stamp.el for a sample. The template looks like one of the following: | |
1750 Time-stamp: <> | |
1751 Time-stamp: " " | |
1752 The time stamp is written between the brackets or quotes, resulting in | |
1753 Time-stamp: <95/01/18 10:20:51 gildea> | |

1760 Commentary: | |
1761 | |
1762 This package can be used to arrange for automatic uncompress of | |

1767 Commentary: | |
1768 | |
1769 This package deals with the primitive form of underlining | |
1770 consisting of prefixing each character with "_\^h". The entry | |
1771 point `underline-region' performs such underlining on a region. | |
1772 The entry point `ununderline-region' removes it. | |

1780 The RCS lock-stealing code doesn't work right unless you use RCS 5.6.2 | |

1782 Even initial checkins will fail if your RCS version is so old that ci | |

1796 Introduction | |
1797 ============ | |
1798 | |
1799 Cookie is a package that implements a connection between an | |
1800 dll (a doubly linked list) and the contents of a buffer. | |
1801 Possible uses are dired (have all files in a list, and show them), | |
1802 buffer-list, kom-prioritize (in the LysKOM elisp client) and | |
1803 others. pcl-cvs.el uses cookie.el. | |
1804 *** pcl-cvs/dll-debug.el | |
1805 Commentary: | |
1806 | |
1807 This is a plug-in replacement for dll.el. It is dreadfully | |
1808 slow, but it facilitates debugging. Don't trust the comments in | |
1809 this file too much. | |

1812 *** pcl-cvs/dll.el | |
1813 Commentary: | |
1814 | |
1815 A doubly linked list consists of one cons cell which holds the tag | |
1816 'DL-LIST in the car cell and a pointer to a dummy node in the cdr | |
1817 cell. The doubly linked list is implemented as a circular list | |
1818 with the dummy node first and last. The dummy node is recognized | |
1819 by comparing it to the node which the cdr of the cons cell points | |
1820 to. | |
1821 | |
1822 *** pcl-cvs/elib-node.el | |
1823 Commentary: | |
1824 | |
1825 A node is implemented as an array with three elements, using | |

1917 Lisp editing commands to go with Lisp major mode. | |
1918 *** prim/loaddefs.el | |
1919 Commentary: | |
1920 | |
1921 You should never need to write autoloads by hand and put them here. | |
1922 | |
1923 It is no longer necessary. Instead use autoload.el to maintain them | |
1924 for you. Just insert ";;;###autoload" before defuns or defmacros you | |
1925 want to be autoloaded, or other forms you want copied into loaddefs.el | |
1926 (defvars, key definitions, etc.). | |
1927 *** prim/loadup-el.el Can't find any Commentary section | |
1928 *** prim/loadup.el | |
1929 Commentary: | |
1930 | |
1931 This is loaded into a bare Emacs to make a dumpable one. | |
1932 *** prim/macros.el | |
1933 Commentary: | |
1934 | |
1935 Extension commands for keyboard macros. These permit you to assign | |
1936 a name to the last-defined keyboard macro, expand and insert the | |
1937 lisp corresponding to a macro, query the user from within a macro, | |
1938 or apply a macro to each line in the reason. | |
1939 | |
1940 This file is largely superseded by edmacro.el as of XEmacs 20.1. -sb | |

1950 *** prim/novice.el | |
1951 Commentary: | |
1952 | |
1953 This mode provides a hook which is, by default, attached to various | |
1954 putatively dangerous commands in a (probably futile) attempt to | |
1955 prevent lusers from shooting themselves in the feet. | |
1956 *** prim/objects.el Can't find any Commentary section | |
1957 *** prim/obsolete.el Can't find any Commentary section | |
1958 *** prim/options.el | |
1959 Commentary: | |
1960 | |
1961 This code provides functions to list and edit the values of all global | |
1962 option variables known to loaded Emacs Lisp code. There are two entry | |
1963 points, `list-options' and `edit' options'. The latter enters a major | |
1964 mode specifically for editing option values. Do `M-x describe-mode' in | |
1965 that context for more details. | |
1966 *** prim/overlay.el Can't find any Commentary section | |
1967 *** prim/page.el | |
1968 Commentary: | |
1969 | |
1970 This code provides the page-oriented movement and selection commands | |
1971 documented in the XEmacs Reference Manual. | |
1972 *** prim/paragraphs.el | |
1973 Commentary: | |

1976 XEmacs Reference Manual. | |

1980 Commentary: | |
1981 | |
1982 This package provides the operations on rectangles that are ocumented | |
1983 in the XEmacs Reference Manual. | |
1984 *** prim/register.el | |
1985 Commentary: | |
1986 | |
1987 This package of functions emulates and somewhat extends the venerable | |
1988 TECO's `register' feature, which permits you to save various useful | |
1989 pieces of buffer state to named variables. The entry points are | |
1990 documented in the XEmacs Reference Manual. | |
1991 *** prim/replace.el | |
1992 Commentary: | |
1993 | |
1994 This package supplies the string and regular-expression replace functions | |
1995 documented in the XEmacs Reference Manual. | |
1996 | |
1997 All the gettext calls are for XEmacs I18N3 message catalog support. | |
1998 *** prim/reposition.el | |
1999 Commentary: | |
2000 | |
2001 Reposition-window makes an entire function definition or comment visible, | |
2002 or, if it is already visible, places it at the top of the window; | |
2003 additional invocations toggle the visibility of comments preceding the | |
2004 code. For the gory details, see the documentation for reposition-window; | |
2005 rather than reading that, you may just want to play with it. | |
2006 | |
2007 This tries pretty hard to do the recentering correctly; the precise | |
2008 action depends on what the buffer looks like. If you find a situation | |
2009 where it doesn't behave well, let me know. This function is modeled | |
2010 after one of the same name in ZMACS, but the code is all-new and the | |
2011 behavior in some situations differs. | |

2014 Commentary: | |
2015 | |
2016 A grab-bag of basic XEmacs commands not specifically related to some | |
2017 major mode or to file-handling. | |
2018 *** prim/sort.el | |

2022 Reference Manual. | |

2027 Commentary: | |
2028 | |
2029 There's not a whole lot in common now with the FSF version, | |
2030 be wary when applying differences. I've left in a number of lines | |
2031 of commentary just to give diff(1) something to synch itself with to | |
2032 provide useful context diffs. -sb | |
2033 *** prim/symbols.el | |
2034 Commentary: | |
2035 | |
2036 The idea behind magic variables is that you can specify arbitrary | |
2037 behavior to happen when setting or retrieving a variable's value. The | |
2038 purpose of this is to make it possible to cleanly provide support for | |
2039 obsolete variables (e.g. unread-command-event, which is obsolete for | |
2040 unread-command-events) and variable compatibility | |
2041 (e.g. suggest-key-bindings, the FSF equivalent of | |
2042 teach-extended-commands-p and teach-extended-commands-timeout). | |

2045 Commentary: | |
2046 | |
2047 Commands to optimize spaces to tabs or expand tabs to spaces in a region | |
2048 (`tabify' and `untabify'). The variable tab-width does the obvious. | |

2054 | |
2055 This file is autoloaded to handle certain conditions | |
2056 detected by the file-locking code within XEmacs. | |
2057 The two entry points are `ask-user-about-lock' and | |
2058 `ask-user-about-supersession-threat'. | |

2064 Commentary: | |
2065 | |
2066 Provides some extra functions for the API to PSGML. | |
2067 | |
2068 *** psgml/psgml-charent.el | |
2069 Commentary: | |
2070 | |
2071 Functions to convert character entities into displayable characters | |
2072 and displayable characters back into character entities. | |

2076 Commentary: | |
2077 | |
2078 Part of major mode for editing the SGML document-markup language. | |
2079 | |
2080 *** psgml/psgml-edit.el | |
2081 Commentary: | |
2082 | |
2083 Part of major mode for editing the SGML document-markup language. | |
2084 | |
2085 *** psgml/psgml-fs.el | |
2086 Commentary: | |
2087 | |
2088 The function `style-format' formats the SGML-file in the current | |
2089 buffer according to the style defined in the file `psgml-style.fs' | |
2090 (or the file given by the variable `fs-style'). | |
2091 | |
2092 To try it load this file and open the test file example.sgml. Then | |
2093 run the emacs command `M-x style-format'. | |
2094 | |
2095 The style file should contain a single Lisp list. The elements of | |
2096 this list, are them self lists, describe the style for an element type. | |
2097 The sublists begin with the generic identifier for the element types and | |
2098 the rest of the list are characteristic/value pairs. | |
2099 | |
2100 E.g. ("p" block t left 4 top 2) | |
2101 | |
2102 Defines the style for p-elements to be blocks with left margin 4 and | |
2103 at least to blank lines before the block. | |
2104 | |
2105 *** psgml/psgml-html.el | |
2106 Commentary: | |
2107 | |
2108 Parts were taken from html-helper-mode and from code by Alastair Burt. | |
2109 | |
2110 Feb 18 1997, Heiko Muenkel: Added the hook variable html-mode-hook. | |
2111 ; With that you can now use the hm--html-minor-mode together | |
2112 ; with this mode. For that you've to add the following line | |
2113 ; to your ~/.emacs: | |
2114 ; (add-hook 'html-mode-hook 'hm--html-minor-mode) | |
2115 *** psgml/psgml-info.el | |
2116 Commentary: | |
2117 | |
2118 This file is an addon to the PSGML package. | |
2119 | |
2120 This file contains some commands to print out information about the | |
2121 current DTD. | |
2122 *** psgml/psgml-other.el | |
2123 Commentary: | |
2124 | |
2125 Part of psgml.el. Code not compatible with XEmacs. | |
2126 | |
2127 *** psgml/psgml-parse.el | |
2128 Commentary: | |
2129 | |
2130 Part of major mode for editing the SGML document-markup language. | |

2140 Commentary: | |
2141 | |
2142 Major mode for editing the SGML document-markup language. | |
2143 *** psgml/tempo.el | |
2144 Commentary: | |
2145 | |
2146 This file provides a simple way to define powerful templates, or | |
2147 macros, if you wish. It is mainly intended for, but not limited to, | |
2148 other programmers to be used for creating shortcuts for editing | |
2149 certain kind of documents. It was originally written to be used by | |
2150 a HTML editing mode written by Nelson Minar <nelson@santafe.edu>, | |
2151 and his html-helper-mode.el is probably the best example of how to | |
2152 use this program. | |

2238 Uses the Emacs 19 terminal initialization features --- won't work with 18. | |
2239 | |
2240 Handles all VT100 clones, including the Apollo terminal. Also handles | |
2241 the VT200 --- its PF- and arrow- keys are different, but all those | |
2242 are really set up by the terminal initialization code, which mines them | |
2243 out of termcap. This package is here to define the keypad comma, dash | |
2244 and period (which aren't in termcap's repertoire) and the function for | |
2245 changing from 80 to 132 columns & vv. | |

2257 Commentary: | |
2258 | |
2259 win32-win.el: this file is loaded from ../lisp/startup.el when it recognizes | |
2260 that win32 windows are to be used. Command line switches are parsed and those | |
2261 pertaining to win32 are processed and removed from the command line. The | |
2262 win32 display is opened and hooks are set for popping up the initial window. | |
2263 | |
2264 startup.el will then examine startup files, and eventually call the hooks | |
2265 which create the first window (s). | |
2266 *** term/wyse50.el | |
2267 Commentary: | |
2268 | |
2269 The Wyse50 is ergonomically wonderful, but its escape-sequence design sucks | |
2270 rocks. The left-arrow key emits a backspace (!) and the down-arrow a line | |
2271 feed (!!). Thus, you have to unbind some commonly-used Emacs keys to | |
2272 enable the arrows. | |

2379 Commentary: | |
2380 | |
2381 This package implements a full-fledged Lisp-style advice mechanism | |
2382 for Emacs Lisp. Advice is a clean and efficient way to modify the | |
2383 behavior of Emacs Lisp functions without having to keep personal | |
2384 modified copies of such functions around. A great number of such | |
2385 modifications can be achieved by treating the original function as a | |
2386 black box and specifying a different execution environment for it | |
2387 with a piece of advice. Think of a piece of advice as a kind of fancy | |
2388 hook that you can attach to any function/macro/subr. | |

2396 *** utils/autoload.el | |
2397 Commentary: | |
2398 | |
2399 This code helps GNU Emacs maintainers keep the loaddefs.el file up to | |
2400 date. It interprets magic cookies of the form ";;;###autoload" in | |
2401 lisp source files in various useful ways. To learn more, read the | |
2402 source; if you're going to use this, you'd better be able to. | |
2403 *** utils/bench.el | |

2423 *** utils/blessmail.el | |
2424 Commentary: | |
2425 | |
2426 This is loaded into a bare Emacs to create the blessmail script, | |
2427 which (on systems that need it) is used during installation | |
2428 to give appropriate permissions to movemail. | |
2429 | |
2430 It has to be done from lisp in order to be sure of getting the | |
2431 correct value of rmail-spool-directory. | |

2434 Commentary: | |
2435 | |
2436 This package provides functions which read a URL (Uniform Resource | |
2437 Locator) from the minibuffer, defaulting to the URL around point, | |
2438 and ask a World-Wide Web browser to load it. It can also load the | |
2439 URL associated with the current buffer. Different browsers use | |
2440 different methods of remote control so there is one function for | |
2441 each supported browser. If the chosen browser is not running, it | |
2442 is started. Currently there is support for: | |

2446 *** utils/derived.el | |
2447 Commentary: | |
2448 | |
2449 GNU Emacs is already, in a sense, object oriented -- each object | |
2450 (buffer) belongs to a class (major mode), and that class defines | |
2451 the relationship between messages (input events) and methods | |
2452 (commands) by means of a keymap. | |
2453 | |
2454 In the mean time, this package offers most of the advantages of | |
2455 full inheritance with the existing major modes. The macro | |
2456 `define-derived-mode' allows the user to make a variant of an existing | |
2457 major mode, with its own keymap. The new mode will inherit the key | |
2458 bindings of its parent, and will, in fact, run its parent first | |
2459 every time it is called. For example, the commands | |

2461 Commentary: | |
2462 | |
2463 WARNING. DANGER. This file reportedly crashes 19.14, use it only with a | |
2464 recent XEmacs. | |

2466 Version: 1.1 | |
2467 *** utils/docref.el | |
2468 Commentary: | |
2469 | |
2470 This package allows you to use a simple form of cross references in | |
2471 your Emacs Lisp documentation strings. Cross-references look like | |
2472 \\(type@[label@]data), where type defines a method for retrieving | |
2473 reference informatin, data is used by a method routine as an argument, | |
2474 and label "represents" the reference in text. If label is absent, data | |
2475 is used instead. | |

2477 *** utils/edmacro.el | |
2478 Commentary: | |
2479 | |
2480 Usage: | |
2481 | |
2482 The `C-x C-k' (`edit-kbd-macro') command edits a keyboard macro | |
2483 in a special buffer. It prompts you to type a key sequence, | |
2484 which should be one of: | |
2485 *** utils/eldoc.el | |
2486 Commentary: | |
2487 | |
2488 This program was inspired by the behavior of the "mouse documentation | |
2489 window" on many Lisp Machine systems; as you type a function's symbol | |
2490 name as part of a sexp, it will print the argument list for that | |
2491 function. Behavior is not identical; for example, you need not actually | |
2492 type the function name, you need only move point around in a sexp that | |
2493 calls it. Also, if point is over a documented variable, it will print | |
2494 the one-line documentation for that variable instead, to remind you of | |
2495 that variable's meaning. | |
2496 *** utils/elp.el | |
2497 Commentary: | |
2498 | |
2499 If you want to profile a bunch of functions, set elp-function-list | |
2500 to the list of symbols, then do a M-x elp-instrument-list. This | |
2501 hacks those functions so that profiling information is recorded | |
2502 whenever they are called. To print out the current results, use | |
2503 M-x elp-results. If you want output to go to standard-output | |
2504 instead of a separate buffer, setq elp-use-standard-output to | |
2505 non-nil. With elp-reset-after-results set to non-nil, profiling | |
2506 information will be reset whenever the results are displayed. You | |
2507 can also reset all profiling info at any time with M-x | |
2508 elp-reset-all. | |
2509 *** utils/facemenu.el | |
2510 Commentary: | |
2511 | |
2512 This file defines a menu of faces (bold, italic, etc) which allows you to | |
2513 set the face used for a region of the buffer. Some faces also have | |
2514 keybindings, which are shown in the menu. Faces with names beginning with | |
2515 "fg:" or "bg:", as in "fg:red", are treated specially. | |
2516 Such faces are assumed to consist only of a foreground (if "fg:") or | |
2517 background (if "bg:") color. They are thus put into the color submenus | |
2518 rather than the general Face submenu. These faces can also be | |
2519 automatically created by selecting the "Other..." menu items in the | |
2520 "Foreground" and "Background" submenus. | |
2521 *** utils/find-gc.el | |
2522 Commentary: | |
2523 | |
2524 Produce in unsafe-list the set of all functions that may invoke GC. | |
2525 This expects the Emacs sources to live in emacs-source-directory. | |
2526 It creates a temporary working directory /tmp/esrc. | |
2527 *** utils/finder.el | |
2528 Commentary: | |
2529 | |
2530 This mode uses the Keywords library header to provide code-finding | |
2531 services by keyword. | |
2532 *** utils/floating-toolbar.el | |
2533 Commentary: | |
2534 | |
2535 The command `floating-toolbar' pops up a small frame | |
2536 containing a toolbar. The command should be bound to a | |
2537 button-press event. If the mouse press happens over an | |
2538 extent that has a non-nil 'floating-toolbar property, the | |
2539 value of that property is the toolbar instantiator that will | |
2540 be displayed. Otherwise the toolbar displayed is taken from | |
2541 the variable `floating-toolbar'. This variable can be made | |
2542 buffer local to produce buffer local floating toolbars. | |
2543 *** utils/flow-ctrl.el | |
2544 Commentary: | |
2545 | |
2546 Terminals that use XON/XOFF flow control can cause problems with | |
2547 GNU Emacs users. This file contains Emacs Lisp code that makes it | |
2548 easy for a user to deal with this problem, when using such a | |
2549 terminal. | |
2550 | |
2551 *** utils/foldout.el | |
2552 Commentary: | |
2553 | |
2554 This file provides folding editor extensions for outline-mode and | |
2555 outline-minor-mode buffers. What's a "folding editor"? Read on... | |
2556 | |
2557 Imagine you're in an outline-mode buffer and you've hidden all the text and | |
2558 subheadings under your level-1 headings. You now want to look at the stuff | |
2559 hidden under one of these headings. Normally you'd do C-c C-e (show-entry) | |
2560 to expose the body or C-c C-i to expose the child (level-2) headings. | |
2561 | |
2562 With foldout, you do C-c C-z (foldout-zoom-subtree). This exposes the body | |
2563 and child subheadings and narrows the buffer so that only the level-1 | |
2564 heading, the body and the level-2 headings are visible. If you now want to | |
2565 look under one of the level-2 headings, position the cursor on it and do C-c | |
2566 C-z again. This exposes the level-2 body and its level-3 child subheadings | |
2567 and narrows the buffer again. You can keep on zooming in on successive | |
2568 subheadings as much as you like. A string in the modeline tells you how | |
2569 deep you've gone. | |

2573 Commentary: | |
2574 | |
2575 Visit a file using a form. | |
2576 | |
2577 Forms mode means visiting a data file which is supposed to consist | |
2578 of records each containing a number of fields. The records are | |
2579 separated by a newline, the fields are separated by a user-defined | |
2580 field separator (default: TAB). | |
2581 When shown, a record is transferred to an Emacs buffer and | |
2582 presented using a user-defined form. One record is shown at a | |
2583 time. | |

2596 Commentary: | |
2597 | |
2598 mail-extract-address-components: (address) | |
2599 | |
2600 Given an RFC-822 ADDRESS, extract full name and canonical address. | |
2601 Returns a list of the form (FULL-NAME CANONICAL-ADDRESS). | |
2602 If no name can be extracted, FULL-NAME will be nil. | |
2603 ADDRESS may be a string or a buffer. If it is a buffer, the visible | |
2604 (narrowed) portion of the buffer will be interpreted as the address. | |
2605 (This feature exists so that the clever caller might be able to avoid | |
2606 consing a string.) | |
2607 If ADDRESS contains more than one RFC-822 address, only the first is | |
2608 returned. | |
2609 | |
2610 *** utils/mail-utils.el | |
2611 Commentary: | |
2612 | |
2613 Utility functions for mail and netnews handling. These handle fine | |
2614 points of header parsing. | |
2615 *** utils/mailpost.el | |
2616 Commentary: | |
2617 | |
2618 Yet another mail interface. this for the rmail system to provide | |
2619 the missing sendmail interface on systems without /usr/lib/sendmail, | |
2620 but with /usr/uci/post. | |
2621 *** utils/map-ynp.el | |
2622 Commentary: | |
2623 | |
2624 map-y-or-n-p is a general-purpose question-asking function. | |
2625 It asks a series of y/n questions (a la y-or-n-p), and decides to | |
2626 applies an action to each element of a list based on the answer. | |
2627 The nice thing is that you also get some other possible answers | |
2628 to use, reminiscent of query-replace: ! to answer y to all remaining | |
2629 questions; ESC or q to answer n to all remaining questions; . to answer | |
2630 y once and then n for the remainder; and you can get help with C-h. | |
2631 *** utils/meese.el | |
2632 Commentary: | |
2633 This file is grossly misnamed. It should be called reno.el. | |

2637 *** utils/redo.el | |
2638 Commentary: | |
2639 | |
2640 Emacs' normal undo system allows you to undo an arbitrary | |
2641 number of buffer changes. These undos are recorded as ordinary | |
2642 buffer changes themselves. So when you break the chain of | |
2643 undos by issuing some other command, you can then undo all | |
2644 the undos. The chain of recorded buffer modifications | |
2645 therefore grows without bound, truncated only at garbage | |
2646 collection time. | |

2650 Commentary: | |
2651 Lisp Package Authors | |
2652 ==================== | |
2653 Reporter was written primarily for Emacs Lisp package authors so | |
2654 that their users can easily report bugs. When invoked, | |
2655 reporter-submit-bug-report will set up an outgoing mail buffer with | |
2656 the appropriate bug report address, including a lisp expression the | |
2657 maintainer of the package can eval to completely reproduce the | |
2658 environment in which the bug was observed (e.g. by using | |
2659 eval-last-sexp). This package proved especially useful during my | |
2660 development of cc-mode, which is highly dependent on its | |
2661 configuration variables. | |

2663 *** utils/ring.el | |
2664 Commentary: | |
2665 | |
2666 This code defines a ring data structure. A ring is a | |
2667 (hd-index length . vector) | |
2668 list. You can insert to, remove from, and rotate a ring. When the ring | |
2669 fills up, insertions cause the oldest elts to be quietly dropped. | |
2670 *** utils/shadowfile.el Can't find any Commentary section | |
2671 *** utils/skeleton.el | |
2672 Commentary: | |
2673 | |
2674 A very concise language extension for writing structured statement | |
2675 skeleton insertion commands for programming language modes. This | |
2676 originated in shell-script mode and was applied to ada-mode's | |
2677 commands which shrunk to one third. And these commands are now | |
2678 user configurable. | |

2680 Commentary: | |
2681 | |
2682 Send Mail to smtp host from smtpmail temp buffer. | |
2683 *** utils/soundex.el | |
2684 Commentary: | |
2685 | |
2686 The Soundex algorithm maps English words into representations of | |
2687 how they sound. Words with vaguely similar sound map to the same string. | |
2688 *** utils/speedbar.el | |
2689 Commentary: | |
2690 | |
2691 The speedbar provides a frame in which files, and locations in | |
2692 files are displayed. These items can be clicked on with mouse-2 | |
2693 in order to make the last active frame display that file location. | |

2701 this implementation and the FSF implementation. | |

2707 manages receiving a stream asynchronously, | |
2708 parsing it into transactions, and then calling | |
2709 handler functions | |
2710 | |
2711 Our basic structure is the queue/process/buffer triple. Each entry | |
2712 of the queue is a regexp/closure/function triple. We buffer | |
2713 bytes from the process until we see the regexp at the head of the | |
2714 queue. Then we call the function with the closure and the | |
2715 collected bytes. | |
2716 *** utils/trace.el | |
2717 Commentary: | |
2718 | |
2719 A simple trace package that utilizes advice.el. It generates trace | |
2720 information in a Lisp-style fashion and inserts it into a trace output | |
2721 buffer. Tracing can be done in the background (or silently) so that | |
2722 generation of trace output won't interfere with what you are currently | |
2723 doing. | |

2725 *** utils/uniquify.el | |
2726 Commentary: | |
2727 | |
2728 Emacs's standard method for making buffer names unique adds <2>, <3>, | |
2729 etc. to the end of (all but one of) the buffers. This file replaces | |
2730 that behavior, for buffers visiting files and dired buffers, with a | |
2731 uniquification that adds parts of the file name until the buffer names | |
2732 are unique. For instance, buffers visiting /u/mernst/tmp/Makefile and | |
2733 /usr/projects/zaphod/Makefile would be named Makefile|tmp and | |
2734 Makefile|zaphod, respectively (instead of Makefile and Makefile<2>). | |
2735 Other buffer name styles are also available. | |

2797 | |
2798 In XEmacs, events are first-class objects. FSF 19 represents them as | |
2799 integers, which obscures the differences between a key gesture and the | |
2800 ancient ASCII code used to represent a particular overlapping subset of them. | |
2801 | |
2802 In XEmacs, keymaps are first-class opaque objects. FSF 19 represents them as | |
2803 complicated combinations of association lists and vectors. If you use the | |
2804 advertised functional interface to manipulation of keymaps, the same code | |
2805 will work in XEmacs, Emacs 18, and GNU Emacs 19; if your code depends | |
2806 on the underlying implementation of keymaps, it will not. | |
2807 | |
2808 XEmacs uses "extents" to represent all non-textual aspects of buffers; | |
2809 FSF 19 uses two distinct objects, "text properties" and "overlays", | |
2810 which divide up the functionality between them. Extents are a | |
2811 superset of the functionality of the two FSF data types. The full FSF | |
2812 19 interface to text properties is supported in XEmacs (with extents | |
2813 being the underlying representation). | |
2814 | |
2815 Extents can be made to be copied into strings, and thus restored by kill | |
2816 and yank. Thus, one can specify this behavior on either "extents" or | |
2817 "text properties", whereas in FSF 19 text properties always have this | |
2818 behavior and overlays never do. | |
2819 | |
2820 Many more packages are provided standard with XEmacs than with FSF 19. | |
2821 | |
2822 Pixmaps of arbitrary size can be embedded in a buffer. | |
2823 | |
2824 Variable width fonts work. | |
2825 | |
2826 The height of a line is the height of the tallest font on that line, instead | |
2827 of all lines having the same height. | |
2828 | |
2829 XEmacs uses the MIT "Xt" toolkit instead of raw Xlib calls, which | |
2830 makes it be a more well-behaved X citizen (and also improves | |
2831 portability). A result of this is that it is possible to include | |
2832 other Xt "Widgets" in the XEmacs window. Also, XEmacs understands the | |
2833 standard Xt command-line arguments. | |
2834 | |
2835 XEmacs provides support for ToolTalk on systems that have it. | |
2836 | |
2837 XEmacs can ask questions using popup dialog boxes. Any command executed from | |
2838 a menu will ask yes/no questions with dialog boxes, while commands executed | |
2839 via the keyboard will use the minibuffer. | |
2840 | |
2841 XEmacs has a built-in toolbar. Four toolbars can actually be configured: | |
2842 top, bottom, left, and right toolbars. | |
2843 | |
2844 XEmacs has vertical and horizontal scrollbars. Unlike in FSF 19 (which | |
2845 provides a primitive form of vertical scrollbar), these are true toolkit | |
2846 scrollbars. A look-alike Motif scrollbar is provided for those who | |
2847 don't have Motif. (Even for those who do, the look-alike may be preferable | |
2848 as it is faster.) | |
2849 | |
2850 If you're running on a machine with audio hardware, you can specify sound | |
2851 files for XEmacs to play instead of the default X beep. See the documentation | |
2852 of the function load-sound-file and the variable sound-alist. | |
2853 | |
2854 An XEmacs frame can be placed within an "external client widget" managed by | |
2855 another application. This allows an application to use an XEmacs frame as its | |
2856 text pane rather than the standard Text widget that is provided with Motif or | |
2857 Athena. XEmacs supports Motif applications, generic Xt (e.g. Athena) | |
2858 applications, and raw Xlib applications. | |
2859 | |
2860 Here are some more specifics about the XEmacs implementation: | |
2861 | |
2862 *** The Input Model | |
2863 ------------------- | |
2864 | |
2865 The fundamental unit of input is an "event" instead of a character. An | |
2866 event is a new data type that contains several pieces of information. | |
2867 There are several kinds of event, and corresponding accessor and utility | |
2868 functions. We tried to abstract them so that they would apply equally | |
2869 well to a number of window systems. | |
2870 | |
2871 NOTE: All timestamps are measured as milliseconds since Emacs started. | |
2872 | |
2873 key_press_event | |
2874 event_channel A token representing which keyboard generated it. | |
2875 For this kind of event, this is a frame object. | |
2876 (This is for eventual support of multiple displays.) | |
2877 timestamp When it happened | |
2878 key What keysym this is; an integer or a symbol. | |
2879 If this is an integer, it will be in the printing | |
2880 ASCII range: >32 and <127. | |
2881 modifiers Bucky-bits on that key: control, meta, etc. | |
2882 For most keys, Shift is not a bit; that is implicit | |
2883 in the keyboard layout. | |
2884 | |
2885 button_press_event | |
2886 button_release_event | |
2887 event_channel A token representing which mouse generated it. | |
2888 For this kind of event, this is a frame object. | |
2889 timestamp When it happened | |
2890 button What button went down or up. | |
2891 modifiers Bucky-bits on that button: shift, control, meta, etc. | |
2892 x, y Where it was at the button-state-change (in pixels). | |
2893 | |
2894 pointer_motion_event | |
2895 event_channel A token representing which mouse generated it. | |
2896 For this kind of event, this is a frame object. | |
2897 timestamp When it happened | |
2898 x, y Where it was after it moved (in pixels). | |
2899 modifiers Bucky-bits down when the motion was detected. | |
2900 (Possibly not all window systems will provide this?) | |
2901 | |
2902 process_event | |
2903 timestamp When it happened | |
2904 process the emacs "process" object in question | |
2905 | |
2906 timeout_event | |
2907 timestamp Now (really, when the timeout was signaled) | |
2908 interval_id The ID returned when the associated call to | |
2909 add_timeout_cb() was made | |
2910 ------ the rest of the fields are filled in by Emacs ----- | |
2911 id_number The Emacs timeout ID for this timeout (more | |
2912 than one timeout event can have the same value | |
2913 here, since Emacs timeouts, as opposed to | |
2914 add_timeout_cb() timeouts, can resignal | |
2915 themselves) | |
2916 function An elisp function to call when this timeout is | |
2917 processed. | |
2918 object The object passed to that function. | |
2919 | |
2920 eval_event | |
2921 timestamp When it happened | |
2922 function An elisp function to call with this event object. | |
2923 object Anything. | |
2924 This kind of event is used internally; sometimes the | |
2925 window system interface would like to inform emacs of | |
2926 some user action (such as focusing on another frame) | |
2927 but needs that to happen synchronously with the other | |
2928 user input, like keypresses. This is useful when | |
2929 events are reported through callbacks rather | |
2930 than in the standard event stream. | |
2931 | |
2932 misc_user_event | |
2933 timestamp When it happened | |
2934 function An elisp function to call with this event object. | |
2935 object Anything. | |
2936 This is similar to an eval_event, except that it is | |
2937 generated by user actions: selections in the | |
2938 menubar or scrollbar actions. It is a "command" | |
2939 event, like key and mouse presses (and unlike mouse | |
2940 motion, process output, and enter and leave window | |
2941 hooks). In many ways, eval_events are not the same | |
2942 as keypresses or misc_user_events. | |
2943 | |
2944 magic_event | |
2945 No user-serviceable parts within. This is for things | |
2946 like KeymapNotify and ExposeRegion events and so on | |
2947 that emacs itself doesn't care about, but which it | |
2948 must do something with for proper interaction with | |
2949 the window system. | |
2950 | |
2951 Magic_events are handled somewhat asynchronously, just | |
2952 like subprocess filters. However, occasionally a | |
2953 magic_event needs to be handled synchronously; in that | |
2954 case, the asynchronous handling of the magic_event will | |
2955 push an eval_event back onto the queue, which will be | |
2956 handled synchronously later. This is one of the | |
2957 reasons why eval_events exist; I'm not entirely happy | |
2958 with this aspect of this event model. | |
2959 | |
2960 | |
2961 The function `next-event' blocks and returns one of the above-described | |
2962 event objects. The function `dispatch-event' takes an event and processes | |
2963 it in the appropriate way. | |
2964 | |
2965 For a process-event, dispatch-event calls the process's handler; for a | |
2966 mouse-motion event, the mouse-motion-handler hook is called, and so on. | |
2967 For magic-events, dispatch-event does window-system-dependent things, | |
2968 including calling some non-window-system-dependent hooks: map-frame-hook, | |
2969 unmap-frame-hook, mouse-enter-frame-hook, and mouse-leave-frame-hook. | |
2970 | |
2971 The function `next-command-event' calls `next-event' until it gets a key or | |
2972 button from the user (that is, not a process, motion, timeout, or magic | |
2973 event). If it gets an event that is not a key or button, it calls | |
2974 `dispatch-event' on it immediately and reads another one. The | |
2975 next-command-event function could be implemented in Emacs Lisp, though it | |
2976 isn't. Generally one should call `next-command-event' instead of | |
2977 `next-event'. | |
2978 | |
2979 read-char calls next-command-event; if it doesn't get an event that can be | |
2980 converted to an ASCII character, it signals an error. Otherwise it returns | |
2981 an integer. | |
2982 | |
2983 The variable `last-command-char' always contains an integer, or nil (if the | |
2984 last read event has no ASCII equivalent, as when it is a mouse-click or a | |
2985 non-ASCII character chord.) | |
2986 | |
2987 The new variable `last-command-event' holds an event object, that could be | |
2988 a non-ASCII character, a button click, a menu selection, etc. | |
2989 | |
2990 The variable `unread-command-char' no longer exists, and has been replaced | |
2991 by `unread-command-events'. With the new event model, it is incorrect for | |
2992 code to do (setq unread-command-char (read-char)), because all user-input | |
2993 can't be represented as ASCII characters. *** This is an incompatible | |
2994 change. Code which sets `unread-command-char' must be updated to use the | |
2995 combination of `next-command-event' and `unread-command-events' instead. | |
2996 | |
2997 The functions `this-command-keys' and `recent-keys' return a vector of | |
2998 event objects, instead of a string of ASCII characters. *** This also | |
2999 is an incompatible change. | |
3000 | |
3001 Almost nothing happens at interrupt level; the SIGIO handler simply sets a | |
3002 flag, and later, the X event queue is scanned for KeyPress events which map | |
3003 to ^G. All redisplay happens in the main thread of the process. | |
3004 | |
3005 | |
3006 *** Keymaps | |
3007 ----------- | |
3008 | |
3009 Instead of keymaps being alists or obarrays, they are a new primary data | |
3010 type. The only user access to the contents of a keymap is through the | |
3011 existing keymap-manipulation functions, and a new function, map-keymap. | |
3012 This means that existing code that manipulates keymaps may need to | |
3013 be changed. | |
3014 | |
3015 One of our goals with the new input and keymap code was to make more | |
3016 character combinations available for binding, besides just ASCII and | |
3017 function keys. We want to be able bind different commands to Control-a | |
3018 and Control-Shift-a; we also want it to be possible for the keys Control-h | |
3019 and Backspace (and Control-M and Return, and Control-I and Tab, etc) to | |
3020 be distinct. | |
3021 | |
3022 One of the most common complaints that new Emacs users have is that backspace | |
3023 is help. The answer is to play around with the keyboard-translate-table, or | |
3024 be lucky enough to have a system administrator who has done this for you | |
3025 already; but if it were possible to bind backspace and C-h to different | |
3026 things, then (under a window manager at least) both backspace and delete | |
3027 would delete a character, and ^H would be help. There's no need to deal | |
3028 with xmodmap, kbd-translate-table, etc. | |
3029 | |
3030 Here are some more examples: suppose you want to bind one function to Tab, | |
3031 and another to Control-Tab. This can't be done if Tab and Control-I are the | |
3032 same thing. What about control keys that have no ASCII equivalent, like | |
3033 Control-< ? One might want that to be bound to set-mark-at-point-min. We | |
3034 want M-C-Backspace to be kill-backward-sexp. But we want M-Backspace to be | |
3035 kill-backward-word. Again, this can't be done if Backspace and C-h are | |
3036 indistinguishable. | |
3037 | |
3038 The user represents keys as a string of ASCII characters (when possible and | |
3039 convenient), or as a vector of event objects, or as a vector of "key | |
3040 description lists", that looks like (control a), or (control meta delete) | |
3041 or (shift f1). The order of the modifier-names is not significant, so | |
3042 (meta control x) and (control meta x) are the same. | |
3043 | |
3044 `define-key' knows how to take any of the above representations and store them | |
3045 into a keymap. When Emacs wants to return a key sequence (this-command-keys, | |
3046 recent-keys, keyboard-macros, and read-key-sequence, for example) it returns | |
3047 a vector of event objects. Keyboard macros can also be represented as ASCII | |
3048 strings or as vectors of key description lists. | |
3049 | |
3050 This is an incompatible change: code which calls `this-command-keys', | |
3051 `recent-keys', `read-key-sequence', or manipulates keyboard-macros probably | |
3052 needs to be changed so that it no longer assumes that the returned value is a | |
3053 string. | |
3054 | |
3055 Control-Shift-a is specified as (control A), not (control shift a), since A | |
3056 is a two-case character. But for keys that don't have an upper case | |
3057 version, like F1, Backspace, and Escape, you use the (shift backspace) syntax. | |
3058 | |
3059 See the doc string for our version of define-key, reproduced below in the | |
3060 `Changed Functions' section. Note that when the KEYS argument is a string, | |
3061 it has the same semantics as the v18 define-key. | |
3062 | |
3063 | |
3064 *** Xt Integration | |
3065 ------------------ | |
3066 | |
3067 The heart of the event loop is implemented in terms of the Xt event functions | |
3068 (specifically XtAppProcessEvent), and uses Xt's concept of timeouts and | |
3069 file-descriptor callbacks, eliminating a large amount of system-dependent code | |
3070 (Xt does it for you.) | |
3071 | |
3072 If Emacs is compiled with support for X, it uses the Xt event loop even when | |
3073 Emacs is not running on an X display (the Xt event loop supports this). This | |
3074 makes it possible to run Emacs on a dumb TTY, and later connect it to one or | |
3075 more X servers. It should also be possible to later connect an existing Emacs | |
3076 process to additional TTY's, although this code is still experimental. (Our | |
3077 intent at this point is not to have an Emacs that is being used by multiple | |
3078 people at the same time: it is to make it possible for someone to go home, log | |
3079 in on a dialup line, and connect to the same Emacs process that is running | |
3080 under X in their office without having to recreate their buffer state and so | |
3081 on.) | |
3082 | |
3083 If Emacs is not compiled with support for X, then it instead uses more general | |
3084 code, something like what v18 does; but this way of doing things is a lot more | |
3085 modular. | |
3086 | |
3087 (Linking Emacs with Xt seems to only add about 300k to the executable size, | |
3088 compared with an Emacs linked with Xlib only.) | |
3089 | |
3090 | |
3091 *** Region Highlighting | |
3092 ----------------------- | |
3093 | |
3094 If the variable `zmacs-regions' is true, then the region between point and | |
3095 mark will be highlighted when "active". Those commands which push a mark | |
3096 (such as C-SPC, and C-x C-x) make the region become "active" and thus | |
3097 highlighted. Most commands (all non-motion commands, basically) cause it to | |
3098 become non-highlighted (non-"active"). Commands that operate on the region | |
3099 (such as C-w, C-x C-l, etc.) only work if the region is in the highlighted | |
3100 state. | |
3101 | |
3102 zmacs-activate-region-hook and zmacs-deactivate-region-hook are run at the | |
3103 appropriate times; under X, zmacs-activate-region-hook makes the X selection | |
3104 be the region between point and mark, thus doing two things at once: making | |
3105 the region and the X selection be the same; and making the region highlight | |
3106 in the same way as the X selection. | |
3107 | |
3108 If `zmacs-regions' is true, then the `mark-marker' command returns nil unless | |
3109 the region is currently in the active (highlighted) state. With an argument | |
3110 of t, this returns the mark (if there is one) regardless of the active-region | |
3111 state. You should *generally* not use the mark unless the region is active, | |
3112 if the user has expressed a preference for the active-region model. Watch | |
3113 out! Moving this marker changes the mark position. If you set the marker not | |
3114 to point anywhere, the buffer will have no mark. | |
3115 | |
3116 In this way, the primary selection is a fairly transitory entity; but | |
3117 when something is copied to the kill ring, it is made the Clipboard | |
3118 selection. It is also stored into CUT_BUFFER0, for compatibility with | |
3119 X applications that don't understand selections (like Emacs18). | |
3120 | |
3121 Compatibility note: if you have code which uses (mark) or (mark-marker), | |
3122 then you need to either: change those calls to (mark t) or (mark-marker t); | |
3123 or simply bind `zmacs-regions' to nil around the call to mark or mark-marker. | |
3124 This is probably the best solution, since it will work in Emacs 18 as well. | |
3125 | |
3126 | |
3127 *** Menubars and Dialog Boxes | |
3128 ----------------------------- | |
3129 | |
3130 Here is an example of a menubar definition: | |
3131 | |
3132 (defvar default-menubar | |
3133 '(("File" ["Open File..." find-file t] | |
3134 ["Save Buffer" save-buffer t] | |
3135 ["Save Buffer As..." write-file t] | |
3136 ["Revert Buffer" revert-buffer t] | |
3137 "-----" | |
3138 ["Print Buffer" lpr-buffer t] | |
3139 "-----" | |
3140 ["Delete Frame" delete-frame t] | |
3141 ["Kill Buffer..." kill-buffer t] | |
3142 ["Exit Emacs" save-buffers-kill-emacs t] | |
3143 ) | |
3144 ("Edit" ["Undo" advertised-undo t] | |
3145 ["Cut" kill-primary-selection t] | |
3146 ["Copy" copy-primary-selection t] | |
3147 ["Paste" yank-clipboard-selection t] | |
3148 ["Clear" delete-primary-selection t] | |
3149 ) | |
3150 ...)) | |
3151 | |
3152 The first element of each menu item is the string to print on the menu. | |
3153 | |
3154 The second element is the callback function; if it is a symbol, it is | |
3155 invoked with `call-interactively.' If it is a list, it is invoked with | |
3156 `eval'. | |
3157 | |
3158 If the second element is a symbol, then the menu also displays the key that | |
3159 is bound to that command (if any). | |
3160 | |
3161 The third element of the menu items determines whether the item is selectable. | |
3162 It may be t, nil, or a form to evaluate. Also, a hook is run just before a | |
3163 menu is exposed, which can be used to change the value of these slots. | |
3164 For example, there is a hook that makes the "undo" menu item be selectable | |
3165 only in the cases when `advertised-undo' would not signal an error. | |
3166 | |
3167 Menus may have other menus nested within them; they will cascade. | |
3168 | |
3169 There are utility functions for adding items to menus, deleting items, | |
3170 disabling them, etc. | |
3171 | |
3172 The function `popup-menu' takes a menu description and pops it up. | |
3173 | |
3174 The function `popup-dialog-box' takes a dialog-box description and pops | |
3175 it up. Dialog box descriptions look a lot like menu descriptions. | |
3176 | |
3177 The menubar, menu, and dialog-box code is implemented as a library, | |
3178 with an interface which hides the toolkit that implements it. | |
3179 | |
3180 | |
3181 *** Isearch Changes | |
3182 ------------------- | |
3183 | |
3184 Isearch has been reimplemented in a different way, adding some new features, | |
3185 and causing a few incompatible changes. | |
3186 | |
3187 - the old isearch-*-char variables are no longer supported. In the old | |
3188 system, one could make ^A mean "repeat the search" by doing something | |
3189 like (setq search-repeat-char ?C-a). In the new system, this is | |
3190 accomplished with | |
3191 | |
3192 (define-key isearch-mode-map "\C-a" 'isearch-repeat-forward) | |
3193 | |
3194 - The advantage of using the normal keymap mechanism for this is that you | |
3195 can bind more than one key to an isearch command: for example, both C-a | |
3196 and C-s could do the same thing inside isearch mode. You can also bind | |
3197 multi-key sequences inside of isearch mode, and bind non-ASCII keys. | |
3198 For example, to use the F1 key to terminate a search: | |
3199 | |
3200 (define-key isearch-mode-map 'f1 'isearch-exit) | |
3201 | |
3202 or to make ``C-c C-c'' terminate a search: | |
3203 | |
3204 (define-key isearch-mode-map "\C-c\C-c" 'isearch-exit) | |
3205 | |
3206 - If isearch is behaving case-insensitively (the default) and you type an | |
3207 upper case character, then the search will become case-sensitive. This | |
3208 can be disabled by setting `search-caps-disable-folding' to nil. | |
3209 | |
3210 - There is a history ring of the strings previously searched for; typing | |
3211 M-p or M-n while searching will cycle through this ring. Typing M-TAB | |
3212 will do completion across the set of items in the history ring. | |
3213 | |
3214 - The ESC key is no longer used to terminate an incremental search. The | |
3215 RET key should be used instead. This change is necessary for it to be | |
3216 possible to bind "meta" characters to isearch commands. | |
3217 | |
3218 | |
3219 *** Startup Code Changes | |
3220 ------------------------ | |
3221 | |
3222 The initial X frame is mapped before the user's .emacs file is executed. | |
3223 Without this, there is no way for the user to see any error messages | |
3224 generated by their .emacs file, any windows created by the .emacs file | |
3225 don't show up, and the copyleft notice isn't shown. | |
3226 | |
3227 The default values for load-path, exec-path, lock-directory, and | |
3228 Info-directory-list are not (necessarily) built into Emacs, but are | |
3229 computed at startup time. | |
3230 | |
3231 First, Emacs looks at the directory in which its executable file resides: | |
3232 | |
3233 o If that directory contains subdirectories named "lisp" and "lib-src", | |
3234 then those directories are used as the lisp library and exec directory. | |
3235 | |
3236 o If the parent of the directory in which the emacs executable is located | |
3237 contains "lisp" and "lib-src" subdirectories, then those are used. | |
3238 | |
3239 o If ../lib/xemacs-<version> (starting from the directory in which the | |
3240 emacs executable is located) contains a "lisp" subdirectory and either | |
3241 a "lib-src" subdirectory or a <configuration-name> subdirectory, then | |
3242 those are used. | |
3243 | |
3244 o If the emacs executable that was run is a symbolic link, then the link | |
3245 is chased, and the resultant directory is checked as above. | |
3246 | |
3247 (Actually, it doesn't just look for "lisp/", it looks for "lisp/prim/", | |
3248 which reduces the chances of a false positive.) | |
3249 | |
3250 If the lisp directory contains subdirectories, they are added to the default | |
3251 load-path as well. If the site-lisp directory exists and contains | |
3252 subdirectories, they are then added. Subdirectories whose names begin with | |
3253 a dot or a hyphen are not added to the load-path. | |
3254 | |
3255 These heuristics fail if the Emacs binary was copied from the main Emacs | |
3256 tree to some other directory, and links for the lisp directory were not put | |
3257 in. This isn't much of a restriction: either make there be subdirectories | |
3258 (or symbolic links) of the directory of the emacs executable, or make the | |
3259 "installed" emacs executable be a symbolic link to an executable in a more | |
3260 appropriate directory structure. For example, this setup works: | |
3261 | |
3262 /usr/local/xemacs/xemacs* ; The executable. | |
3263 /usr/local/xemacs/lisp/ ; The associated directories. | |
3264 /usr/local/xemacs/etc/ ; Any of the files in this list | |
3265 /usr/local/xemacs/lock/ ; could be symbolic links as well. | |
3266 /usr/local/xemacs/info/ | |
3267 | |
3268 As does this: | |
3269 | |
3270 /usr/local/bin/xemacs -> ../xemacs/src/xemacs-19.14 ; A link... | |
3271 /usr/local/xemacs/src/xemacs-19.14* ; The executable, | |
3272 /usr/local/xemacs/lisp/ ; and the rest of | |
3273 /usr/local/xemacs/etc/ ; the source tree | |
3274 /usr/local/xemacs/lock/ | |
3275 /usr/local/xemacs/info/ | |
3276 | |
3277 This configuration might be used for a multi-architecture installation; assume | |
3278 that $LOCAL refers to a directory which contains only files specific to a | |
3279 particular architecture (i.e., executables) and $SHARED refers to those files | |
3280 which are not machine specific (i.e., lisp code and documentation.) | |
3281 | |
3282 $LOCAL/bin/xemacs@ -> $LOCAL/xemacs-19.14/xemacs* | |
3283 $LOCAL/xemacs-19.14/lisp@ -> $SHARED/xemacs-19.14/lisp/ | |
3284 $LOCAL/xemacs-19.14/etc@ -> $SHARED/xemacs-19.14/etc/ | |
3285 $LOCAL/xemacs-19.14/info@ -> $SHARED/xemacs-19.14/info/ | |
3286 | |
3287 The following would also work, but the above is probably more attractive: | |
3288 | |
3289 $LOCAL/bin/xemacs* | |
3290 $LOCAL/bin/lisp@ -> $SHARED/xemacs-19.14/lisp/ | |
3291 $LOCAL/bin/etc@ -> $SHARED/xemacs-19.14/etc/ | |
3292 $LOCAL/bin/info@ -> $SHARED/xemacs-19.14/info/ | |
3293 | |
3294 If Emacs can't find the requisite directories, it writes a message like this | |
3295 (or some appropriate subset of it) to stderr: | |
3296 | |
3297 WARNING: | |
3298 couldn't find an obvious default for load-path, exec-directory, and | |
3299 lock-directory, and there were no defaults specified in paths.h when | |
3300 Emacs was built. Perhaps some directories don't exist, or the Emacs | |
3301 executable, /cadillac-th/jwz/somewhere/xemacs is in a strange place? | |
3302 | |
3303 Without both exec-directory and load-path, Emacs will be very broken. | |
3304 Consider making a symbolic link from /cadillac-th/jwz/somewhere/etc | |
3305 to wherever the appropriate Emacs etc/ directory is, and from | |
3306 /cadillac-th/jwz/somewhere/lisp/ to wherever the appropriate Emacs | |
3307 lisp library is. | |
3308 | |
3309 Without lock-directory set, file locking won't work. Consider | |
3310 creating /cadillac-th/jwz/somewhere/lock as a directory or symbolic | |
3311 link for use as the lock directory. | |
3312 | |
3313 The default installation tree is the following: | |
3314 | |
3315 /usr/local/bin/b2m ; | |
3316 ctags ; executables that | |
3317 emacsclient ; should be in | |
3318 etags ; user's path | |
3319 xemacs -> xemacs-<version> ; | |
3320 xemacs ; | |
3321 /usr/local/lib/xemacs/site-lisp | |
3322 /usr/local/lib/xemacs/lock | |
3323 /usr/local/lib/xemacs-<version>/etc ; architecture ind. files | |
3324 /usr/local/lib/xemacs-<version>/info | |
3325 /usr/local/lib/xemacs-<version>/lisp | |
3326 /usr/local/lib/xemacs-<version>/<configuration> ; binaries emacs may run | |
3327 | |
3328 | |
3329 *** X Resources | |
3330 --------------- | |
3331 | |
3332 (Note: This section is copied verbatim from the XEmacs Reference Manual.) | |
3333 | |
3334 The Emacs resources are generally set per-frame. Each Emacs frame | |
3335 can have its own name or the same name as another, depending on the | |
3336 name passed to the `make-frame' function. | |
3337 | |
3338 You can specify resources for all frames with the syntax: | |
3339 | |
3340 Emacs*parameter: value | |
3341 | |
3342 or | |
3343 | |
3344 Emacs*EmacsFrame.parameter:value | |
3345 | |
3346 You can specify resources for a particular frame with the syntax: | |
3347 | |
3348 Emacs*FRAME-NAME.parameter: value | |
3349 | |
3350 | |
3351 **** Geometry Resources | |
3352 ----------------------- | |
3353 | |
3354 To make the default size of all Emacs frames be 80 columns by 55 | |
3355 lines, do this: | |
3356 | |
3357 Emacs*EmacsFrame.geometry: 80x55 | |
3358 | |
3359 To set the geometry of a particular frame named `fred', do this: | |
3360 | |
3361 Emacs*fred.geometry: 80x55 | |
3362 | |
3363 Important! Do not use the following syntax: | |
3364 | |
3365 Emacs*geometry: 80x55 | |
3366 | |
3367 You should never use `*geometry' with any X application. It does not | |
3368 say "make the geometry of Emacs be 80 columns by 55 lines." It really | |
3369 says, "make Emacs and all subwindows thereof be 80x55 in whatever units | |
3370 they care to measure in." In particular, that is both telling the | |
3371 Emacs text pane to be 80x55 in characters, and telling the menubar pane | |
3372 to be 80x55 pixels, which is surely not what you want. | |
3373 | |
3374 As a special case, this geometry specification also works (and sets | |
3375 the default size of all Emacs frames to 80 columns by 55 lines): | |
3376 | |
3377 Emacs.geometry: 80x55 | |
3378 | |
3379 since that is the syntax used with most other applications (since most | |
3380 other applications have only one top-level window, unlike Emacs). In | |
3381 general, however, the top-level shell (the unmapped ApplicationShell | |
3382 widget named `Emacs' that is the parent of the shell widgets that | |
3383 actually manage the individual frames) does not have any interesting | |
3384 resources on it, and you should set the resources on the frames instead. | |
3385 | |
3386 The `-geometry' command-line argument sets only the geometry of the | |
3387 initial frame created by Emacs. | |
3388 | |
3389 A more complete explanation of geometry-handling is | |
3390 | |
3391 * The `-geometry' command-line option sets the `Emacs.geometry' | |
3392 resource, that is, the geometry of the ApplicationShell. | |
3393 | |
3394 * For the first frame created, the size of the frame is taken from | |
3395 the ApplicationShell if it is specified, otherwise from the | |
3396 geometry of the frame. | |
3397 | |
3398 * For subsequent frames, the order is reversed: First the frame, and | |
3399 then the ApplicationShell. | |
3400 | |
3401 * For the first frame created, the position of the frame is taken | |
3402 from the ApplicationShell (`Emacs.geometry') if it is specified, | |
3403 otherwise from the geometry of the frame. | |
3404 | |
3405 * For subsequent frames, the position is taken only from the frame, | |
3406 and never from the ApplicationShell. | |
3407 | |
3408 This is rather complicated, but it does seem to provide the most | |
3409 intuitive behavior with respect to the default sizes and positions of | |
3410 frames created in various ways. | |
3411 | |
3412 | |
3413 **** Iconic Resources | |
3414 --------------------- | |
3415 | |
3416 Analogous to `-geometry', the `-iconic' command-line option sets the | |
3417 iconic flag of the ApplicationShell (`Emacs.iconic') and always applies | |
3418 to the first frame created regardless of its name. However, it is | |
3419 possible to set the iconic flag on particular frames (by name) by using | |
3420 the `Emacs*FRAME-NAME.iconic' resource. | |
3421 | |
3422 | |
3423 **** Resource List | |
3424 ------------------ | |
3425 | |
3426 Emacs frames accept the following resources: | |
3427 | |
3428 `geometry' (class `Geometry'): string | |
3429 Initial geometry for the frame. *Note Geometry Resources:: for a | |
3430 complete discussion of how this works. | |
3431 | |
3432 `iconic' (class `Iconic'): boolean | |
3433 Whether this frame should appear in the iconified state. | |
3434 | |
3435 `internalBorderWidth' (class `InternalBorderWidth'): int | |
3436 How many blank pixels to leave between the text and the edge of the | |
3437 window. | |
3438 | |
3439 `interline' (class `Interline'): int | |
3440 How many pixels to leave between each line (may not be | |
3441 implemented). | |
3442 | |
3443 `menubar' (class `Menubar'): boolean | |
3444 Whether newly-created frames should initially have a menubar. Set | |
3445 to true by default. | |
3446 | |
3447 `initiallyUnmapped' (class `InitiallyUnmapped'): boolean | |
3448 Whether XEmacs should leave the initial frame unmapped when it | |
3449 starts up. This is useful if you are starting XEmacs as a server | |
3450 (e.g. in conjunction with gnuserv or the external client widget). | |
3451 You can also control this with the `-unmapped' command-line option. | |
3452 | |
3453 `barCursor' (class `BarColor'): boolean | |
3454 Whether the cursor should be displayed as a bar, or the | |
3455 traditional box. | |
3456 | |
3457 `textPointer' (class `Cursor'): cursor-name | |
3458 The cursor to use when the mouse is over text. This resource is | |
3459 used to initialize the variable `x-pointer-shape'. | |
3460 | |
3461 `selectionPointer' (class `Cursor'): cursor-name | |
3462 The cursor to use when the mouse is over a selectable text region | |
3463 (an extent with the `highlight' property; for example, an Info | |
3464 cross-reference). This resource is used to initialize the variable | |
3465 `x-selection-pointer-shape'. | |
3466 | |
3467 `spacePointer' (class `Cursor'): cursor-name | |
3468 The cursor to use when the mouse is over a blank space in a buffer | |
3469 (that is, after the end of a line or after the end-of-file). This | |
3470 resource is used to initialize the variable | |
3471 `x-nontext-pointer-shape'. | |
3472 | |
3473 `modeLinePointer' (class `Cursor'): cursor-name | |
3474 The cursor to use when the mouse is over a mode line. This | |
3475 resource is used to initialize the variable `x-mode-pointer-shape'. | |
3476 | |
3477 `gcPointer' (class `Cursor'): cursor-name | |
3478 The cursor to display when a garbage-collection is in progress. | |
3479 This resource is used to initialize the variable | |
3480 `x-gc-pointer-shape'. | |
3481 | |
3482 `scrollbarPointer' (class `Cursor'): cursor-name | |
3483 The cursor to use when the mouse is over the scrollbar. This | |
3484 resource is used to initialize the variable | |
3485 `x-scrollbar-pointer-shape'. | |
3486 | |
3487 `pointerColor' (class `Foreground'): color-name | |
3488 `pointerBackground' (class `Background'): color-name | |
3489 The foreground and background colors of the mouse cursor. These | |
3490 resources are used to initialize the variables | |
3491 `x-pointer-foreground-color' and `x-pointer-background-color'. | |
3492 | |
3493 `scrollBarWidth' (class `ScrollBarWidth'): integer | |
3494 How wide the vertical scrollbars should be, in pixels; 0 means no | |
3495 vertical scrollbars. You can also use a resource specification of | |
3496 the form `*scrollbar.width', or the usual toolkit scrollbar | |
3497 resources: `*XmScrollBar.width' (Motif), `*XlwScrollBar.width' | |
3498 (Lucid), or `*Scrollbar.thickness' (Athena). We don't recommend | |
3499 that you use the toolkit resources, though, because they're | |
3500 dependent on how exactly your particular build of XEmacs was | |
3501 configured. | |
3502 | |
3503 `scrollBarHeight' (class `ScrollBarHeight'): integer | |
3504 How high the horizontal scrollbars should be, in pixels; 0 means no | |
3505 horizontal scrollbars. You can also use a resource specification | |
3506 of the form `*scrollbar.height', or the usual toolkit scrollbar | |
3507 resources: `*XmScrollBar.height' (Motif), `*XlwScrollBar.height' | |
3508 (Lucid), or `*Scrollbar.thickness' (Athena). We don't recommend | |
3509 that you use the toolkit resources, though, because they're | |
3510 dependent on how exactly your particular build of XEmacs was | |
3511 configured. | |
3512 | |
3513 `scrollBarPlacement' (class `ScrollBarPlacement'): string | |
3514 Where the horizontal and vertical scrollbars should be positioned. | |
3515 This should be one of the four strings `bottom-left', | |
3516 `bottom-right', `top-left', and `top-right'. Default is | |
3517 `bottom-right' for the Motif and Lucid scrollbars and | |
3518 `bottom-left' for the Athena scrollbars. | |
3519 | |
3520 `topToolBarHeight' (class `TopToolBarHeight'): integer | |
3521 `bottomToolBarHeight' (class `BottomToolBarHeight'): integer | |
3522 `leftToolBarWidth' (class `LeftToolBarWidth'): integer | |
3523 `rightToolBarWidth' (class `RightToolBarWidth'): integer | |
3524 Height and width of the four possible toolbars. | |
3525 | |
3526 `topToolBarShadowColor' (class `TopToolBarShadowColor'): color-name | |
3527 `bottomToolBarShadowColor' (class `BottomToolBarShadowColor'): color-name | |
3528 Color of the top and bottom shadows for the toolbars. NOTE: These | |
3529 resources do *not* have anything to do with the top and bottom | |
3530 toolbars (i.e. the toolbars at the top and bottom of the frame)! | |
3531 Rather, they affect the top and bottom shadows around the edges of | |
3532 all four kinds of toolbars. | |
3533 | |
3534 `topToolBarShadowPixmap' (class `TopToolBarShadowPixmap'): pixmap-name | |
3535 `bottomToolBarShadowPixmap' (class `BottomToolBarShadowPixmap'): pixmap-name | |
3536 Pixmap of the top and bottom shadows for the toolbars. If set, | |
3537 these resources override the corresponding color resources. NOTE: | |
3538 These resources do *not* have anything to do with the top and | |
3539 bottom toolbars (i.e. the toolbars at the top and bottom of the | |
3540 frame)! Rather, they affect the top and bottom shadows around the | |
3541 edges of all four kinds of toolbars. | |
3542 | |
3543 `toolBarShadowThickness' (class `ToolBarShadowThickness'): integer | |
3544 Thickness of the shadows around the toolbars, in pixels. | |
3545 | |
3546 `visualBell' (class `VisualBell'): boolean | |
3547 Whether XEmacs should flash the screen rather than making an | |
3548 audible beep. | |
3549 | |
3550 `bellVolume' (class `BellVolume'): integer | |
3551 Volume of the audible beep. | |
3552 | |
3553 `useBackingStore' (class `UseBackingStore'): boolean | |
3554 Whether XEmacs should set the backing-store attribute of the X | |
3555 windows it creates. This increases the memory usage of the X | |
3556 server but decreases the amount of X traffic necessary to update | |
3557 the screen, and is useful when the connection to the X server goes | |
3558 over a low-bandwidth line such as a modem connection. | |
3559 | |
3560 | |
3561 **** Face Resources | |
3562 ------------------- | |
3563 | |
3564 The attributes of faces are also per-frame. They can be specified as: | |
3565 | |
3566 Emacs.FACE_NAME.parameter: value | |
3567 | |
3568 (*do not* use `Emacs*FACE_NAME...') | |
3569 | |
3570 or | |
3571 | |
3572 Emacs*FRAME_NAME.FACE_NAME.parameter: value | |
3573 | |
3574 Faces accept the following resources: | |
3575 | |
3576 `attributeFont' (class `AttributeFont'): font-name | |
3577 The font of this face. | |
3578 | |
3579 `attributeForeground' (class `AttributeForeground'): color-name | |
3580 `attributeBackground' (class `AttributeBackground'): color-name | |
3581 The foreground and background colors of this face. | |
3582 | |
3583 `attributeBackgroundPixmap' (class `AttributeBackgroundPixmap'): file-name | |
3584 The name of an XBM file (or XPM file, if your version of Emacs | |
3585 supports XPM), to use as a background stipple. | |
3586 | |
3587 `attributeUnderline' (class `AttributeUnderline'): boolean | |
3588 Whether text in this face should be underlined. | |
3589 | |
3590 All text is displayed in some face, defaulting to the face named | |
3591 `default'. To set the font of normal text, use | |
3592 `Emacs*default.attributeFont'. To set it in the frame named `fred', use | |
3593 `Emacs*fred.default.attributeFont'. | |
3594 | |
3595 These are the names of the predefined faces: | |
3596 | |
3597 `default' | |
3598 Everything inherits from this. | |
3599 | |
3600 `bold' | |
3601 If this is not specified in the resource database, Emacs tries to | |
3602 find a bold version of the font of the default face. | |
3603 | |
3604 `italic' | |
3605 If this is not specified in the resource database, Emacs tries to | |
3606 find an italic version of the font of the default face. | |
3607 | |
3608 `bold-italic' | |
3609 If this is not specified in the resource database, Emacs tries to | |
3610 find a bold-italic version of the font of the default face. | |
3611 | |
3612 `modeline' | |
3613 This is the face that the modeline is displayed in. If not | |
3614 specified in the resource database, it is determined from the | |
3615 default face by reversing the foreground and background colors. | |
3616 | |
3617 `highlight' | |
3618 This is the face that highlighted extents (for example, Info | |
3619 cross-references and possible completions, when the mouse passes | |
3620 over them) are displayed in. | |
3621 | |
3622 `left-margin' | |
3623 `right-margin' | |
3624 These are the faces that the left and right annotation margins are | |
3625 displayed in. | |
3626 | |
3627 `zmacs-region' | |
3628 This is the face that mouse selections are displayed in. | |
3629 | |
3630 `text-cursor' | |
3631 This is the face that the cursor is displayed in. | |
3632 | |
3633 `isearch' | |
3634 This is the face that the matched text being searched for is | |
3635 displayed in. | |
3636 | |
3637 `info-node' | |
3638 This is the face of info menu items. If unspecified, it is copied | |
3639 from `bold-italic'. | |
3640 | |
3641 `info-xref' | |
3642 This is the face of info cross-references. If unspecified, it is | |
3643 copied from `bold'. (Note that, when the mouse passes over a | |
3644 cross-reference, the cross-reference's face is determined from a | |
3645 combination of the `info-xref' and `highlight' faces.) | |
3646 | |
3647 Other packages might define their own faces; to see a list of all | |
3648 faces, use any of the interactive face-manipulation commands such as | |
3649 `set-face-font' and type `?' when you are prompted for the name of a | |
3650 face. | |
3651 | |
3652 If the `bold', `italic', and `bold-italic' faces are not specified | |
3653 in the resource database, then XEmacs attempts to derive them from the | |
3654 font of the default face. It can only succeed at this if you have | |
3655 specified the default font using the XLFD (X Logical Font Description) | |
3656 format, which looks like | |
3657 | |
3658 *-courier-medium-r-*-*-*-120-*-*-*-*-*-* | |
3659 | |
3660 If you use any of the other, less strict font name formats, some of | |
3661 which look like | |
3662 | |
3663 lucidasanstypewriter-12 | |
3664 fixed | |
3665 9x13 | |
3666 | |
3667 then XEmacs won't be able to guess the names of the bold and italic | |
3668 versions. All X fonts can be referred to via XLFD-style names, so you | |
3669 should use those forms. See the man pages for `X(1)', `xlsfonts(1)', | |
3670 and `xfontsel(1)'. | |
3671 | |
3672 | |
3673 **** Widgets | |
3674 ------------ | |
3675 | |
3676 There are several structural widgets between the terminal EmacsFrame | |
3677 widget and the top level ApplicationShell; the exact names and types of | |
3678 these widgets change from release to release (for example, they changed | |
3679 in 19.9, 19.10, 19.12, and 19.13) and are subject to further change in | |
3680 the future, so you should avoid mentioning them in your resource database. | |
3681 The above-mentioned syntaxes should be forward-compatible. As of 19.14, | |
3682 the exact widget hierarchy is as follows: | |
3683 | |
3684 INVOCATION-NAME "shell" "container" FRAME-NAME | |
3685 x-emacs-application-class "TopLevelEmacsShell" "EmacsManager" "EmacsFrame" | |
3686 | |
3687 (for normal frames) | |
3688 | |
3689 or | |
3690 | |
3691 INVOCATION-NAME "shell" "container" FRAME-NAME | |
3692 x-emacs-application-class "TransientEmacsShell" "EmacsManager" "EmacsFrame" | |
3693 | |
3694 (for popup/dialog-box frames) | |
3695 | |
3696 where INVOCATION-NAME is the terminal component of the name of the | |
3697 XEmacs executable (usually `xemacs'), and `x-emacs-application-class' | |
3698 is generally `Emacs'. | |
3699 | |
3700 | |
3701 **** Menubar Resources | |
3702 ---------------------- | |
3703 | |
3704 As the menubar is implemented as a widget which is not a part of | |
3705 XEmacs proper, it does not use the face mechanism for specifying fonts | |
3706 and colors: It uses whatever resources are appropriate to the type of | |
3707 widget which is used to implement it. | |
3708 | |
3709 If Emacs was compiled to use only the Motif-lookalike menu widgets, | |
3710 then one way to specify the font of the menubar would be | |
3711 | |
3712 Emacs*menubar*font: *-courier-medium-r-*-*-*-120-*-*-*-*-*-* | |
3713 | |
3714 If the Motif library is being used, then one would have to use | |
3715 | |
3716 Emacs*menubar*fontList: *-courier-medium-r-*-*-*-120-*-*-*-*-*-* | |
3717 | |
3718 because the Motif library uses the `fontList' resource name instead | |
3719 of `font', which has subtly different semantics. | |
3720 | |
3721 The same is true of the scrollbars: They accept whichever resources | |
3722 are appropriate for the toolkit in use. | |
3723 | |
3724 | |
3725 *** Source Code Highlighting | |
3726 ---------------------------- | |
3727 | |
3728 It's possible to have your buffers "decorated" with fonts or colors | |
3729 indicating syntactic structures (such as strings, comments, function names, | |
3730 "reserved words", etc.). In XEmacs, the preferred way to do this is with | |
3731 font-lock-mode; activate it by adding the following code to your .emacs file: | |
3732 | |
3733 (add-hook 'emacs-lisp-mode-hook 'turn-on-font-lock) | |
3734 (add-hook 'c-mode-hook 'turn-on-font-lock) | |
3735 (add-hook 'c++-mode-hook 'turn-on-font-lock) | |
3736 (add-hook 'dired-mode-hook 'turn-on-font-lock) | |
3737 ...etc... | |
3738 | |
3739 To customize it, see the descriptions of the function `font-lock-mode' and | |
3740 the variables `font-lock-keywords', `c-font-lock-keywords', etc. | |
3741 | |
3742 There exist several other source code highlighting packages, but font-lock | |
3743 does one thing that most others don't do: highlights as you type new text; | |
3744 and one thing that no others do: bases part of its decoration on the | |
3745 syntax table of the major mode. Font-lock has C-level support to do this | |
3746 efficiently, so it should also be significantly faster than the others. | |
3747 | |
3748 If there's something that another highlighting package does that you can't | |
3749 make font-lock do, let us know. We would prefer to consolidate all of the | |
3750 desired functionality into one package rather than ship several different | |
3751 packages which do essentially the same thing in different ways. | |
3752 | |
3753 | |
3754 ** Differences Between XEmacs and Emacs 18 | |
3755 ========================================== | |
3756 | |
3757 Auto-configure support has been added, so it should be fairly easy to compile | |
3758 XEmacs on different systems. If you have any problems or feedback about | |
3759 compiling on your system, please let us know. | |
3760 | |
3761 We have reimplemented the basic input model in a more general way; instead of | |
3762 X input being a special-case of the normal ASCII input stream, XEmacs has a | |
3763 concept of "input events", and ASCII characters are a subset of that. The | |
3764 events that XEmacs knows about are not X events, but are a generalization of | |
3765 them, so that XEmacs can eventually be ported to different window systems. | |
3766 | |
3767 We have reimplemented keymaps so that sequences of events can be stored into | |
3768 them instead of just ASCII codes; it is possible to, for example, bind | |
3769 different commands to each of the chords Control-h, Control-H, Backspace, | |
3770 Control-Backspace, and Super-Shift-Backspace. Key bindings, function key | |
3771 bindings, and mouse bindings live in the same keymaps. | |
3772 | |
3773 Input and display of all ISO-8859-1 characters is supported. | |
3774 | |
3775 You can have multiple X windows ("frames" in XEmacs terminology). | |
3776 | |
3777 XEmacs has objects called "extents" and "faces", which are roughly | |
3778 analogous to Epoch's "buttons," "zones," and "styles." An extent is a | |
3779 region of text (a start position and an end position) and a face is a | |
3780 collection of textual attributes like fonts and colors. Every extent | |
3781 is displayed in some "face", so changing the properties of a face | |
3782 immediately updates the display of all associated extents. Faces can | |
3783 be frame-local: you can have a region of text which displays with | |
3784 completely different attributes when its buffer is viewed from a | |
3785 different X window. | |
3786 | |
3787 The display attributes of faces may be specified either in lisp or through | |
3788 the X resource manager. | |
3789 | |
3790 Pixmaps of arbitrary size can be embedded in a buffer. | |
3791 | |
3792 Variable width fonts work. | |
3793 | |
3794 The height of a line is the height of the tallest font on that line, instead | |
3795 of all lines having the same height. | |
3796 | |
3797 XEmacs uses the MIT "Xt" toolkit instead of raw Xlib calls, which | |
3798 makes it be a more well-behaved X citizen (and also improves | |
3799 portability). A result of this is that it is possible to include | |
3800 other Xt "Widgets" in the XEmacs window. Also, XEmacs understands the | |
3801 standard Xt command-line arguments. | |
3802 | |
3803 XEmacs understands the X11 "Selection" mechanism; it's possible to define | |
3804 and customize selection converter functions and new selection types from | |
3805 Emacs Lisp, without having to recompile XEmacs. | |
3806 | |
3807 XEmacs provides support for ToolTalk on systems that have it. | |
3808 | |
3809 XEmacs supports the Zmacs/Lispm style of region highlighting, where the | |
3810 region between the point and mark is highlighted when in its "active" state. | |
3811 | |
3812 XEmacs has a menubar, whose contents are customizable from emacs-lisp. | |
3813 This menubar looks Motif-ish, but does not require Motif. If you already | |
3814 own Motif, however, you can configure XEmacs to use a *real* Motif menubar | |
3815 instead. | |
3816 | |
3817 XEmacs can ask questions using popup dialog boxes. Any command executed from | |
3818 a menu will ask yes/no questions with dialog boxes, while commands executed | |
3819 via the keyboard will use the minibuffer. | |
3820 | |
3821 XEmacs has vertical and horizontal scrollbars. | |
3822 | |
3823 The initial load-path is computed at run-time, instead of at compile-time. | |
3824 This means that if you move the XEmacs executable and associated directories | |
3825 to somewhere else, you don't have to recompile anything. | |
3826 | |
3827 You can specify what the title of the XEmacs windows and icons should be | |
3828 with the variables `frame-title-format' and `frame-icon-title-format', | |
3829 which have the same syntax as `mode-line-format'. | |
3830 | |
3831 XEmacs now supports floating-point numbers. | |
3832 | |
3833 XEmacs now knows about timers directly, instead of them being simulated by | |
3834 a subprocess. | |
3835 | |
3836 XEmacs understands truenames, and can be configured to notice when you are | |
3837 visiting two names of the same file. See the variables find-file-use-truenames | |
3838 and find-file-compare-truenames. | |
3839 | |
3840 If you're running on a machine with audio hardware, you can specify sound | |
3841 files for XEmacs to play instead of the default X beep. See the documentation | |
3842 of the function load-sound-file and the variable sound-alist. | |
3843 | |
3844 An XEmacs frame can be placed within an "external client widget" managed by | |
3845 another application. This allows an application to use an XEmacs frame as its | |
3846 text pane rather than the standard Text widget that is provided with Motif or | |
3847 Athena. XEmacs supports Motif applications, generic Xt (e.g. Athena) | |
3848 applications, and raw Xlib applications. | |
3849 | |
3850 Random changes to the emacs-lisp library: (some of this was not written by | |
3851 us, but is included because it's free software and we think it's good stuff) | |
3852 | |
3853 - there is a new optimizing byte-compiler | |
3854 - there is a new abbrev-based mail-alias mechanism | |
3855 - the -*- line can contain local-variable settings | |
3856 - there is a new TAGS package | |
3857 - there is a new VI-emulation mode (viper) | |
3858 - there is a new implementation of Dired | |
3859 - there is a new implementation of Isearch | |
3860 - the VM package for reading mail is provided | |
3861 - the W3 package for browsing the World Wide Web hypertext information | |
3862 system is provided | |
3863 - the Hyperbole package, a programmable information management and | |
3864 hypertext system | |
3865 - the OO-Browser package, a multi-language object-oriented browser | |
3866 | |
3867 There are many more specifics in the "Miscellaneous Changes" section, below. | |
3868 | |
3869 The online Emacs Manual and Emacs-Lisp Manual are now both relatively | |
3870 up-to-date. | |
3871 | |
3872 ** Major Differences Between 19.13 and 19.14 | |
3873 ============================================ | |
3874 | |
3875 XEmacs has a new address! The canonical ftp site is now | |
3876 ftp.xemacs.org:/pub/xemacs and the Web page is now at | |
3877 http://www.xemacs.org/. All mailing lists now have @xemacs.org | |
3878 addresses. For the time being the @cs.uiuc.edu addresses will | |
3879 continue to function. | |
3880 | |
3881 This is a major new release. Many features have been added, as well | |
3882 as many bugs fixed. The Motif menubar has still _NOT_ been fixed for | |
3883 19.14. You should use the Lucid menubar instead. | |
3884 | |
3885 | |
3886 | |
3887 Major user-visible changes: | |
3888 --------------------------- | |
3889 | |
3890 -- Color support in TTY mode is provided. You have to have a TTY capable | |
3891 of displaying them, such as color xterm or the console under Linux. | |
3892 If your terminal type supports colors (e.g. `xterm-color'), XEmacs | |
3893 will automatically notice this and start using color. | |
3894 | |
3895 -- blink-cursor-mode enables a blinking text cursor. There is a | |
3896 menubar option for this also. | |
3897 | |
3898 -- auto-show-mode is turned on by default; this means that XEmacs | |
3899 will automatically scroll a window horizontally as necessary to | |
3900 keep point in view. | |
3901 | |
3902 -- a file dialog box is provided and will be used whenever you | |
3903 are prompted for a filename as a result of a menubar selection. | |
3904 | |
3905 -- XEmacs can be compiled with built-in GIF, JPEG, and PNG support. | |
3906 The GIF libraries are supplied with XEmacs; for JPEG and PNG, | |
3907 you have to obtain the appropriate libraries (this is well- | |
3908 documented). This makes image display much easier and faster under | |
3909 W3 (the web browser) and TM (adds MIME support to VM and GNUS; | |
3910 not yet included with XEmacs but will be in 19.15). | |
3911 | |
3912 -- XEmacs provides a really nice mode (PSGML with "Wing improvements") | |
3913 for editing HTML and other SGML documents. It parses the document, | |
3914 and as a result it does proper indentation, can show you the context | |
3915 you're in, the allowed tags at a particular position, etc. | |
3916 | |
3917 -- XEmacs comes standard with modes for editing Java and VRML code, | |
3918 including font-lock support. | |
3919 | |
3920 -- GNUS 5.2 comes standard with XEmacs. | |
3921 | |
3922 -- You can now embed colors in the modeline, with different sections | |
3923 of the modeline responding appropriately to various mouse gestures: | |
3924 For example, clicking on the "read-only" indicator toggles the | |
3925 read-only status of a buffer, and clicking on the buffer name | |
3926 cycles to the next buffer. Pressing button3 on these areas brings | |
3927 up a popup menu of appropriate commands. | |
3928 | |
3929 -- There is a much nicer mode for completion lists and such. | |
3930 At the minibuffer prompt, if you hit page-up or Meta-V, the completion | |
3931 buffer will be displayed (if it wasn't already), you're moved into | |
3932 it, and can move around and select filenames using the arrow keys | |
3933 and the return key. Rather than a cursor, a filename is highlighted, | |
3934 and the arrow keys change which filename is highlighted. | |
3935 | |
3936 -- The edit-faces subsystem has also been much improved, in somewhat | |
3937 similar ways to the completion list improvements. | |
3938 | |
3939 -- Many improvements were made to the multi-device support. | |
3940 We now provide an auxiliary utility called "gnuattach" that | |
3941 lets you connect to an existing XEmacs process and display | |
3942 a TTY frame on the current TTY connection, and commands | |
3943 `make-frame-on-display' (with a corresponding menubar entry) | |
3944 and `make-frame-on-tty' for more easily creating frames on | |
3945 new TTY or X connections. | |
3946 | |
3947 -- We have incorporated nearly all of the functionality of GNU Emacs | |
3948 19.30 into XEmacs. This includes support for lazy-loaded | |
3949 byte code and documentation strings, improved paragraph filling, | |
3950 better support for margins within documents, v19 regular expression | |
3951 routines (including caching of compiled regexps), etc. | |
3952 | |
3953 -- In accordance with GNU Emacs 19.30, the following key binding | |
3954 changes have been made: | |
3955 | |
3956 C-x ESC -> C-x ESC ESC | |
3957 ESC ESC -> ESC : | |
3958 ESC ESC ESC is "abort anything" (keyboard-escape-quit). | |
3959 | |
3960 -- All major packages have been updated to their latest-released | |
3961 versions. | |
3962 | |
3963 -- XEmacs now gracefully handles a full colormap (such as typically | |
3964 results when running Netscape). The nearest available color | |
3965 is automatically substituted. | |
3966 | |
3967 -- Many bug fixes to the subprocess/PTY code, ps-print, menubar | |
3968 functions, `set-text-properties', DEC Alpha support, toolbar | |
3969 resizing (the "phantom VM toolbar" bug), and lots and lots | |
3970 of other things were made. | |
3971 | |
3972 -- The ncurses library (a replacement for curses, found especially | |
3973 under Linux) is supported, and will be automatically used | |
3974 if it can be found. | |
3975 | |
3976 -- You can now undo in the minibuffer. | |
3977 | |
3978 -- Surrogate minibuffers now work. These are also sometimes referred | |
3979 to as "global" minibuffers. | |
3980 | |
3981 -- font-lock has been merged with GNU Emacs 19.30, improved defaults | |
3982 have been added, and changes have been made to the way it is | |
3983 configured. | |
3984 | |
3985 -- Many, many modes have menubar entries for them. | |
3986 | |
3987 -- `recover-session' lets you recover whatever files can be recovered | |
3988 after your XEmacs process has died unexpectedly. | |
3989 | |
3990 -- C-h k followed by a toolbar button press correctly reports | |
3991 the binding of the toolbar button. | |
3992 | |
3993 -- `function-key-map', `key-translation-map', and `keyboard-translate-table' | |
3994 are now correctly implemented. | |
3995 | |
3996 -- `show-message-log' (and its menubar entry under Edit) have been | |
3997 removed; instead use `view-lossage' (and its menubar entry under | |
3998 Help). | |
3999 | |
4000 -- There is a standard menubar entry for specifying which browser | |
4001 (Netscape, W3, Mosaic, etc.) to use when dispatching URL's | |
4002 in mail, Usenet news, etc. | |
4003 | |
4004 -- Improved native sound support under Linux. | |
4005 | |
4006 -- Lots of other things we forgot to mention. | |
4007 | |
4008 | |
4009 | |
4010 Significant Lisp-level changes: | |
4011 ------------------------------- | |
4012 | |
4013 -- Many improvements to the E-Lisp documentation have been made; | |
4014 it should now be up-to-date and complete in nearly all cases. | |
4015 | |
4016 -- XEmacs has extensive documentation on its internals, for | |
4017 would-be C hackers. | |
4018 | |
4019 -- Common-Lisp support (the CL package) is now dumped standard | |
4020 into XEmacs. No more need for (require 'cl) or anything | |
4021 like that. | |
4022 | |
4023 -- Full support for extents and text properties over strings is | |
4024 provided. | |
4025 | |
4026 -- The extent properties `start-open', `end-open', `start-closed', | |
4027 and `end-closed' now work correctly w.r.t. text properties. | |
4028 | |
4029 -- The `face' property of extents and text properties can now | |
4030 be a list. | |
4031 | |
4032 -- The `mouse-face' property from GNU Emacs is now supported. | |
4033 It supersedes the `highlight' property. | |
4034 | |
4035 -- `enriched' and `facemenu' packages from GNU Emacs have been ported. | |
4036 | |
4037 -- New functions for easier creation of dialog boxes: | |
4038 `get-dialog-box-response', `message-box', and `message-or-box'. | |
4039 | |
4040 -- `function-min-args' and `function-max-args' allow you to determine | |
4041 the minimum and maximum allowed arguments for any type of | |
4042 function (i.e. subr, lambda expression, byte-compiled function, etc.). | |
4043 | |
4044 -- Some C-level support for doing E-Lisp profiling is provided. | |
4045 See `start-profiling', `stop-profiling', and | |
4046 `pretty-print-profiling-info'. | |
4047 | |
4048 -- `current-process-time' reports the user, system, and real times | |
4049 for the currently running XEmacs process. | |
4050 | |
4051 -- `next-window', `previous-window', `next-frame', `previous-frame', | |
4052 `other-window', `get-lru-window', etc. have an extra device | |
4053 argument that allows you to restrict which devices it includes | |
4054 (normally all devices). Some functions that incorrectly ignored | |
4055 frames on different devices (e.g. C-x 0) are fixed. | |
4056 | |
4057 -- new functions `run-hook-with-args-until-success', | |
4058 `run-hook-with-args-until-failure'. | |
4059 | |
4060 -- generalized facility for local vs. global hooks. See `make-local-hook', | |
4061 `add-hook'. | |
4062 | |
4063 -- New functions for querying the window tree: `frame-leftmost-window', | |
4064 `frame-rightmost-window', `window-first-hchild', `window-first-vchild', | |
4065 `window-next-child', `window-previous-child', and `window-parent'. | |
4066 | |
4067 -- Epoch support works. This gets you direct access to some X events | |
4068 and objects (e.g. properties and property-notify events). | |
4069 | |
4070 -- The multi-device support has been majorly revamped. There is now | |
4071 a new concept of "consoles" (devices grouped together under a | |
4072 common keyboard/mouse), console-local variables, and a generalized | |
4073 concept of device/console connection. | |
4074 | |
4075 -- `display-buffer' synched with GNU Emacs 19.30, giving you lots of | |
4076 wondrous cruft such as | |
4077 -- unsplittable frames | |
4078 -- pop-up-frames, pop-up-frame-function | |
4079 -- special-display-buffer-names, special-display-regexps, | |
4080 special-display-function | |
4081 -- same-window-buffer-names, same-window-regexps | |
4082 | |
4083 -- XEmacs has support for accessing DBM- and/or DB-format databases, | |
4084 provided that you have the appropriate libraries on your system. | |
4085 | |
4086 -- There is a new font style: "strikethru" fonts. | |
4087 | |
4088 -- New data type "weak list", which is a list with special | |
4089 garbage-collection properties, similar to weak hash tables. | |
4090 | |
4091 -- `set-face-parent' makes one face inherit all properties from another. | |
4092 | |
4093 -- The junky frame parameters mechanism has been revamped as | |
4094 frame properties, which a standard property-list interface. | |
4095 | |
4096 -- Lots and lots of functions for working with property lists have | |
4097 been added. | |
4098 | |
4099 -- New functions `push-window-configuration', `pop-window-configuration', | |
4100 `unpop-window-configuration' for maintain a stack of window | |
4101 configurations. | |
4102 | |
4103 -- Many fixups to the glyph code; icons and mouse pointers are now | |
4104 properly merged into the glyph mechanism. | |
4105 | |
4106 -- `set-specifier' works more sensibly, like `set-face-property'. | |
4107 | |
4108 -- Many new specifiers for individually controlling toolbar height/width | |
4109 and visibility and text cursor visibility. | |
4110 | |
4111 -- New face `text-cursor' controls the colors of the text cursor. | |
4112 | |
4113 -- Many new variables for turning on debug information about the | |
4114 inner workings of XEmacs. | |
4115 | |
4116 -- Hash tables can now compare their keys using `equal' or `eql' | |
4117 as well as `eq'. | |
4118 | |
4119 -- Other things too numerous to mention. | |
4120 | |
4121 | |
4122 | |
4123 Significant configuration/build changes: | |
4124 ---------------------------------------- | |
4125 | |
4126 -- You can disable TTY support, toolbar support, scrollbar support, | |
4127 menubar support, and/or dialog box support at configure time | |
4128 to save memory. | |
4129 | |
4130 -- New configure option `--extra-verbose' shows the diagnostic | |
4131 output from feature testing; this should help track down | |
4132 problems with incorrect feature detection. | |
4133 | |
4134 -- `dont-have-xmu' is now `with-xmu', with the reversed sense. | |
4135 (It defaults to `yes'.) | |
4136 | |
4137 -- `with-mocklisp' lets you add Mocklisp support if you really | |
4138 need this. | |
4139 | |
4140 -- `with-term' for adding TERM support for Linux users. | |
4141 | |
4142 | |
4143 | |
4144 ** Major Differences Between 19.12 and 19.13 | |
4145 ============================================ | |
4146 | |
4147 This is primarily a bug-fix release. Lots of bugs have been fixed. | |
4148 Hopefully only a few have been introduced. The most noteworthy bug | |
4149 fixes are: | |
4150 | |
4151 -- There should be no more problems connecting XEmacs to an X | |
4152 server over SLIP or other slow connections. | |
4153 -- Periodic crashes when using the Buffers menu should be gone. | |
4154 -- etags would sometimes erase the current buffer; it doesn't | |
4155 any more. | |
4156 -- XEmacs will correctly exit if the X server dies. | |
4157 -- uniconified frames are displayed properly under TVTWM. | |
4158 -- Breakage in `add-menu-item' / `add-menu-button' is fixed. | |
4159 | |
4160 The Motif menubar has _NOT_ been fixed for 19.13. You should use the | |
4161 Lucid menubar instead. | |
4162 | |
4163 Multi-device support should now be working properly. You can now open | |
4164 an X device after having started out on a TTY device. | |
4165 | |
4166 Background pixmaps now work. See `set-face-background-pixmap'. | |
4167 | |
4168 Echo area messages are now saved to a buffer, " *Message Log*". To | |
4169 see this buffer, use the command `show-message-log'. It is possible | |
4170 to filter the message which are actually included by modifying the | |
4171 variables `log-message-ignore-regexps' and `log-message-ignore-labels'. | |
4172 | |
4173 You can now control which warnings you want to see. See | |
4174 `display-warning-suppressed-classes' and friends. | |
4175 | |
4176 You can now set the default location of an "other window" from the | |
4177 Options menu. | |
4178 | |
4179 "Save Options" now saves the state of all faces. | |
4180 | |
4181 You can choose which file "Save Options" writes into; see | |
4182 `save-options-file'. | |
4183 | |
4184 XPM support is no longer required for the toolbar. | |
4185 | |
4186 The relocating allocator is now enabled by default whenever possible. | |
4187 This allows buffer memory to be returned to the system when no longer | |
4188 in use which helps keep XEmacs process size down. | |
4189 | |
4190 The ability to have captioned toolbars has been added. Currently only | |
4191 the default toolbar actually has a captioned version provided. A new | |
4192 specifier variable, `toolbar-buttons-captioned-p' controls whether the | |
4193 toolbar is captioned. | |
4194 | |
4195 A copy of the XEmacs FAQ is now included and is available through info. | |
4196 | |
4197 The on-line E-Lisp reference manual has been significantly updated. | |
4198 | |
4199 There is now audio support under Linux. | |
4200 | |
4201 Modifier keys can now be sticky. This is controlled by the variable | |
4202 `modifier-keys-are-sticky'. | |
4203 | |
4204 manual-entry should now work correctly under Irix with the penalty of | |
4205 a longer startup time the first time it is invoked. If you are having | |
4206 problems with this on another system try setting | |
4207 `Manual-use-subdirectory-list' to t. | |
4208 | |
4209 make-tty-device no longer automatically creates the first frame. | |
4210 | |
4211 Rectangular regions now work correctly. | |
4212 | |
4213 ediff no longer sets synchronize-minibuffers to t unless you first set | |
4214 ediff-synchronize-minibuffers | |
4215 | |
4216 keyboard-translate-table has been implemented. This means that the | |
4217 `enable-flow-control' command for dealing with TTY connections that | |
4218 filter out ^S and ^Q now works. | |
4219 | |
4220 You can now create frames that are initially unmapped and frames that | |
4221 are "transient for another frame", meaning that they behave more like | |
4222 dialog-box frames. | |
4223 | |
4224 Other E-Lisp changes: | |
4225 | |
4226 -- Specifier `menubar-visible-p' for controlling menubar visibility | |
4227 -- Local command hooks should be set using `local-pre-command-hook' | |
4228 and `local-post-command-hook' instead of making the global | |
4229 equivalents be buffer-local. | |
4230 -- `quit-char', `help-char', `meta-prefix-char' can be any key specifier | |
4231 instead of just an integer. | |
4232 -- new functions `add-async-timeout' and `disable-async-timeout'. | |
4233 These let you create asynchronous timeouts, which are like | |
4234 normal timeouts except that they're executed even during | |
4235 running Lisp code. Use this with care! | |
4236 -- `debug-on-error' and `stack-trace-on-error' now enter the debugger | |
4237 only when an *unhandled* error occurs. If you want the old | |
4238 behavior, use `debug-on-signal' and `stack-trace-on-signal'. | |
4239 -- \U, \L, \u, \l, \E recognized specially in `replace-match'. | |
4240 These are standard ex/perl commands for changing the case of | |
4241 replaced text. | |
4242 -- New function event-matches-key-specifier-p. This provides | |
4243 a clean way of comparing keypress events with key specifiers | |
4244 such as 65, (shift home), etc. without having to resort | |
4245 to ugly `character-to-event' / `event-to-character' hacks. | |
4246 -- New function `add-to-list' | |
4247 -- New Common-Lisp functions `some', `every', `notevery', `notany', | |
4248 `adjoin', `union', `intersection', `set-difference', | |
4249 `set-exclusive-or', `subsetp' | |
4250 -- `remove-face-property' provides a clean way of removing a | |
4251 face property. | |
4252 | |
4253 Many of the Emacs Lisp packages have been updated. Some of the new | |
4254 Emacs Lisp packages --- | |
4255 | |
4256 ada-mode: major mode for editing Ada source | |
4257 | |
4258 arc-mode: simple editing of archives | |
4259 | |
4260 auto-show-mode: automatically scrolls horizontally to keep point on-screen | |
4261 | |
4262 completion: dynamic word completion mode | |
4263 | |
4264 dabbrev: the dynamic abbrev package has been rewritten and is much | |
4265 more powerful -- e.g. it searches in other buffers as well | |
4266 as the current one | |
4267 | |
4268 easymenu: menu support package | |
4269 | |
4270 live-icon: makes frame icons represent the current frame contents | |
4271 | |
4272 mailcrypt 3.2: mail encryption with PGP; included but v2.4 is still | |
4273 the default | |
4274 | |
4275 two-column: for editing two-column text | |
4276 | |
4277 | |
4278 ** Major Differences Between 19.11 and 19.12 | |
4279 ============================================ | |
4280 | |
4281 This is a huge new release. Almost every aspect of XEmacs has been changed | |
4282 at least somewhat. The highlights are: | |
4283 | |
4284 -- TTY support (includes face support) | |
4285 -- new redisplay engine; should be faster, less buggy, and more powerful | |
4286 -- terminology change from "screen" to "frame" | |
4287 -- built-in toolbar | |
4288 -- toolbar support added to many packages | |
4289 -- multiple device support (still in beta; improvements to come in | |
4290 19.13) | |
4291 -- Purify used to ensure that there are no memory leaks or memory corruption | |
4292 problems | |
4293 -- horizontal and vertical scrollbars in all windows | |
4294 -- new Lucid (i.e. look-alike Motif) scrollbar widget | |
4295 -- stay-up menus in the Lucid (look-alike Motif) menubar widget | |
4296 -- 3-d modeline | |
4297 -- new extents engine; should be faster, less buggy, and more powerful | |
4298 -- much more powerful control over faces | |
4299 -- expanded menubar | |
4300 -- more work on synching with GNU Emacs 19.28 | |
4301 -- new packages: Hyperbole, OOBR (object browser), hm--html-menus, viper, | |
4302 lazy-lock.el, ksh-mode.el, rsz-minibuf.el | |
4303 -- package updates for all major packages | |
4304 -- dynodump package for Solaris: provides proper undumping and portable | |
4305 binaries across different OS versions and machine types | |
4306 -- Greatly expanded concept of "glyphs" (pixmaps etc. in a buffer) | |
4307 -- built-in support for displaying X-Faces, if the X-Face library is | |
4308 available | |
4309 -- built-in support for SOCKS if the SOCKS library is available | |
4310 -- graceful behavior when the colormap is full (e.g. Netscape ate | |
4311 all the colors) | |
4312 -- built-in MD5 (secure hashing function) support | |
4313 | |
4314 | |
4315 More specific information: | |
4316 | |
4317 *** TTY Support | |
4318 --------------- | |
4319 | |
4320 The long-awaited TTY support is now available. XEmacs will start up | |
4321 in TTY mode (using the tty you started XEmacs from) if the DISPLAY | |
4322 environment variable is not set or if you use the `-nw' option. | |
4323 | |
4324 Faces are available on TTY's. For a demonstration, try editing a C | |
4325 file and turning on font-lock-mode. | |
4326 | |
4327 You can also connect to additional TTY's using `make-tty-device', | |
4328 whether your first frame was a TTY or an X window. This ability is | |
4329 not yet completely finished. | |
4330 | |
4331 The full event-loop capabilities (processes, timeouts, etc.) are | |
4332 available on TTY's. | |
4333 | |
4334 | |
4335 | |
4336 *** New Redisplay Engine | |
4337 ------------------------ | |
4338 | |
4339 The redisplay engine has been rewritten to improve its efficiency and | |
4340 to increase its functionality. It should also be significantly more | |
4341 bug-free than the previous redisplay engine. | |
4342 | |
4343 A line that is not big enough to display at the bottom of the window | |
4344 will normally be clipped (so that it is partially visible) rather than | |
4345 not displayed at all. The variable `pixel-vertical-clip-threshold' | |
4346 can be used to control the minimum space that must be available for a | |
4347 line to be clipped rather than not displayed at all. | |
4348 | |
4349 Tabs are displayed in such a way that things line up fairly well even | |
4350 in the presence of variable-width fonts and/or lines with | |
4351 multiply-sized fonts. | |
4352 | |
4353 Display tables are implemented, through the specifier variable | |
4354 `current-display-table'. They can be buffer-local, window-local, | |
4355 frame-local, or device-local. See below for info about specifiers. | |
4356 | |
4357 | |
4358 | |
4359 *** Toolbar | |
4360 ----------- | |
4361 | |
4362 There is now built-in support for a toolbar. A sample toolbar is | |
4363 visible by default at the top of the frame. Four separate toolbars | |
4364 can be configured (at the top, bottom, left, and right of the frame). | |
4365 The toolbar specification is similar to the menubar specification. | |
4366 The up, down, and disabled glyphs of a toolbar button can be | |
4367 separately controlled. Explanatory text can be echoed in the echo | |
4368 area when the mouse passes over a toolbar button. The size, contents, | |
4369 and visibility of the various toolbars can be controlled on a | |
4370 per-buffer, per-window, per-frame, and per-device basis through the | |
4371 use of specifiers. See the chapter on toolbars in the Lisp Reference | |
4372 Manual (included with XEmacs) for more information. | |
4373 | |
4374 The toolbar color and shadow thicknesses are currently controlled only | |
4375 through `modify-frame-parameters' and through X resources. We are | |
4376 planning on making these controllable through specifiers as well. (Our | |
4377 hope is to make `modify-frame-parameters' obsolete, as it is a clunky | |
4378 and not very powerful mechanism.) | |
4379 | |
4380 Info, GNUS, VM, W3, and various other packages include custom toolbars | |
4381 with them. | |
4382 | |
4383 | |
4384 | |
4385 *** Menubar | |
4386 ----------- | |
4387 | |
4388 Stay-up menus are implemented in the look-alike Motif menubar. | |
4389 | |
4390 The default menubar has been expanded to include most commonly-used | |
4391 functions in XEmacs. | |
4392 | |
4393 The options menu has been greatly expanded to include many more | |
4394 options. | |
4395 | |
4396 The menubar specification format has been greatly expanded. Per-menu | |
4397 activation hooks can be specified through the :filter keyword (thus | |
4398 obsoleting `activate-menubar-hook'); this allows for fast response | |
4399 time when you have a large and complex menu. You can dynamically | |
4400 control whether menu items are present through the :included and | |
4401 :config keywords. (The latter keyword implements a simple menubar | |
4402 configuration scheme, in conjunction with the variable | |
4403 `menubar-configuration'.) Many different menu-item separators (single | |
4404 or double line; solid or dashed; flat, etched-in, or etched-out) are | |
4405 available. See the chapter on menus in the Lisp Reference Manual for | |
4406 more information about all of this. | |
4407 | |
4408 New functions `add-submenu' and `add-menu-button' are available. | |
4409 These supersede the older `add-menu' and `add-menu-item' functions, | |
4410 and provide a more powerful and consistent interface. | |
4411 | |
4412 New convenience functions for popping up the part or all of the | |
4413 menubar in a pop-up menu are available: `popup-menubar-menu' and | |
4414 `popup-buffer-menu'. | |
4415 | |
4416 Menus are now incrementally constructed greatly improving menubar | |
4417 response time. | |
4418 | |
4419 | |
4420 | |
4421 *** Scrollbars | |
4422 -------------- | |
4423 | |
4424 A look-alike Motif scrollbar is now included with XEmacs. No longer | |
4425 will you have to suffer with ugly Athena scrollbars. | |
4426 | |
4427 Windows can now have horizontal scrollbars. Normally they are visible | |
4428 when the window's buffer is set to truncate lines rather than wrap | |
4429 them (e.g. `(setq truncate-lines t)'). | |
4430 | |
4431 All windows, not only the right-most ones, can have vertical | |
4432 scrollbars. | |
4433 | |
4434 The functions to change a scrollbar's width have been superseded by | |
4435 the specifier variables `scrollbar-width' and `scrollbar-height'. | |
4436 This allows their values to be controlled on a buffer-local, | |
4437 window-local, frame-local, and device-local basis. See below. | |
4438 | |
4439 The scrollbars interact better with the event loop (for example, you | |
4440 can type `C-h k', do a scrollbar action, and see a description of this | |
4441 scrollbar action printed as if you had pressed a key sequence or | |
4442 selected a menu item). | |
4443 | |
4444 The scrollbar behavior can be reprogrammed, by advising the | |
4445 `scrollbar-*' functions. | |
4446 | |
4447 | |
4448 | |
4449 *** Key Bindings | |
4450 ---------------- | |
4451 | |
4452 The oft-used function `goto-line' now has its own binding: M-g. | |
4453 | |
4454 New bindings are available for scrolling the "other" window: M-next, | |
4455 M-prior, M-home, M-end. (On many keyboards, `next' and `prior' | |
4456 labelled `PgUp' and `PgDn'.) | |
4457 | |
4458 You can reactivate a deactivated Zmacs region, without having any | |
4459 other effects, with the binding M-C-z. | |
4460 | |
4461 The bindings `M-u', `M-l', and `M-c' now work on the region (if a | |
4462 region is active) or work on a word, as before. | |
4463 | |
4464 Shift-Control-G forces a "critical quit", which drops immediately into | |
4465 the debugger; see below. | |
4466 | |
4467 | |
4468 | |
4469 *** Modeline | |
4470 ------------ | |
4471 | |
4472 The modeline can now have a 3-d look; this is enabled by default. The | |
4473 specifier variable `modeline-shadow-thickness' controls the size. | |
4474 | |
4475 The modeline can now be turned off on a per-buffer, per-window, | |
4476 per-frame, or per-device basis. The specifier variable | |
4477 `has-modeline-p' controls whether the modeline is visible. See below | |
4478 for details about the vastly powerful specifier mechanism. | |
4479 | |
4480 The modeline functions and variables have been renamed to be | |
4481 `*-modeline-*' rather than `*-mode-line-*'. Aliases are provided for | |
4482 all the old names. | |
4483 | |
4484 Variable width fonts now work correctly when used in the modeline. | |
4485 | |
4486 | |
4487 | |
4488 *** Minibuffer, Echo Area | |
4489 ------------------------- | |
4490 | |
4491 The minibuffer is no longer constrained to be one line high. The | |
4492 package rsz-minibuf.el is included to automatically resize the | |
4493 minibuffer when its contents are too big; enable this with | |
4494 `resize-minibuffer-mode'. | |
4495 | |
4496 The echo area is now a true buffer, called " *Echo Area*". This | |
4497 allows you to customize the echo area behavior through | |
4498 before-change-functions and after-change-functions. | |
4499 | |
4500 | |
4501 | |
4502 *** Specifiers | |
4503 -------------- | |
4504 | |
4505 XEmacs has a new concept called "specifiers", used to configure most | |
4506 display options (toolbar size and contents, scrollbar size, face | |
4507 properties, modeline visibility and shadow-thickness, glyphs, display | |
4508 tables, etc.). We are planning on converting all display | |
4509 characteristics to use specifiers, and obsoleting the clunky functions | |
4510 `frame-parameters' and `modify-frame-parameters'. Specifically: | |
4511 | |
4512 -- You can specify values (called "instantiators") for particular | |
4513 "locales" (i.e. buffers, windows, frames, devices, or a global value). | |
4514 When determining what the actual value (or "instance") of a specifier | |
4515 is, the specifications that are provided are searched from most | |
4516 specific (i.e. buffer-local) to most general (i.e. global), looking | |
4517 for a matching one. | |
4518 | |
4519 -- You can specify multiple instantiators for a particular locale. | |
4520 For example, when specifying what the foreground color of a face | |
4521 is in a particular buffer, you could specify two instantiators: | |
4522 "dark sea green" and "green". The color would then be dark sea | |
4523 green on devices that recognize that color, and green on other | |
4524 devices. You have effectively provided a fallback value to make | |
4525 sure you get reasonable behavior on all devices. | |
4526 | |
4527 -- You can add one or more tags to an instantiator, where a tag | |
4528 is a symbol that has been previously registered with XEmacs. | |
4529 This allows you to identify your instantiators for later | |
4530 removal in a way that won't interfere with other applications | |
4531 using the same specifier. Furthermore, particular tags can | |
4532 be restricted to match only particular sorts of devices. | |
4533 Any tagged instantiator will be ignored if the device over which | |
4534 it is being instanced does not match any of its tags. This | |
4535 allows you, for example, to restrict an instantiator to a | |
4536 particular device type (X or TTY) and/or class (color, grayscale, | |
4537 or mono). (You might want to specify, for example, that a | |
4538 particular face is displayed in green on color devices and is | |
4539 underlined on mono devices.) | |
4540 | |
4541 -- A full API is provided for manipulating specifiers, and full | |
4542 documentation is provided in the Lisp Reference Manual. | |
4543 | |
4544 | |
4545 | |
4546 *** Basic Lisp Stuff | |
4547 -------------------- | |
4548 | |
4549 Common-Lisp backquote syntax is recognized. For example, the old | |
4550 expression | |
4551 | |
4552 (` (a b (, c))) | |
4553 | |
4554 can now be written | |
4555 | |
4556 `(a b ,c) | |
4557 | |
4558 The old backquote syntax is still accepted. | |
4559 | |
4560 The new function `type-of' returns a symbol describing the type of a | |
4561 Lisp object (`integer', `string', `symbol', etc.) | |
4562 | |
4563 Symbols beginning with a colon (called "keywords") are treated | |
4564 specially in that they are automatically made self-evaluating when | |
4565 they are interned into `obarray'. The new function `keywordp' returns | |
4566 whether a symbol begins with a colon. | |
4567 | |
4568 `get', `put', and `remprop' have been generalized to allow you to set | |
4569 and retrieve properties on many different kinds of objects: symbols, | |
4570 strings, faces, glyphs, and extents (for extents, however, this is not | |
4571 yet implemented). They are joined by a new function `object-props' | |
4572 that returns all of the properties that have been set on an object. | |
4573 | |
4574 New functions `plists-eq' and `plists-equal' are provided for | |
4575 comparing property lists (a property list is an alternating list | |
4576 of keys and values). | |
4577 | |
4578 The Common-Lisp functions `caar', `cadr', `cdar', `cddr', `caaar', etc. | |
4579 (up to four a's and/or d's), `first', `second', `third', etc. (up to | |
4580 `tenth'), `last', `rest', and `endp' have been added, for more | |
4581 convenient manipulation of lists. | |
4582 | |
4583 New function `mapvector' maps over a sequence and returns a vector | |
4584 of the results, analogous to `mapcar'. | |
4585 | |
4586 New functions `rassoc', `remassoc', `remassq', `remrassoc', and | |
4587 `remrassq' are provided for working with alists. | |
4588 | |
4589 New functions `defvaralias', `variable-alias' and `indirect-variable' | |
4590 are provided for creating variable aliases. | |
4591 | |
4592 Strings have a modified-tick that is bumped every time a string | |
4593 is modified in-place with `aset' or `fillarray'. This is retrieved | |
4594 with the new function `string-modified-tick'. | |
4595 | |
4596 New macro `push' destructively adds an element to the beginning of a | |
4597 list. New macro `pop' destructively removes and returns the first | |
4598 element of a list. | |
4599 | |
4600 | |
4601 | |
4602 *** Buffers | |
4603 ----------- | |
4604 | |
4605 Most functions that operate on buffer text now take an optional BUFFER | |
4606 argument, specifying which buffer they operate on. (Previously, they | |
4607 always operated on the current buffer.) | |
4608 | |
4609 The new function `transpose-regions' is provided, ported from GNU | |
4610 Emacs. | |
4611 | |
4612 The new function `save-current-buffer' works like `save-excursion' | |
4613 but only saves the current buffer, not the location of point in | |
4614 that buffer. | |
4615 | |
4616 | |
4617 | |
4618 *** Devices | |
4619 ----------- | |
4620 | |
4621 XEmacs has a new concept of "device", which is represents a particular | |
4622 X display or TTY connection. `make-frame' has a new, optional device | |
4623 parameter that allows you to specify which device the frame is to be | |
4624 created on. | |
4625 | |
4626 Multiple simultaneous TTY and/or X connections may be made. The | |
4627 specifier mechanism provides reasonable behavior of glyphs, faces, | |
4628 etc. over heterogeneous device types and over devices whose individual | |
4629 capabilities may vary. | |
4630 | |
4631 There is also a device type called "stream" that represents a STDIO | |
4632 device that has no redisplay or cursor-motion capabilities, such as | |
4633 the "glass terminal" that XEmacs uses when it is run noninteractively. | |
4634 There is not all that much you can do with stream devices currently; | |
4635 please let us know if there are good uses you can think of for this | |
4636 capability. (For example, log files?) | |
4637 | |
4638 A new device API is provided. Functions are provided such as | |
4639 `device-name' (the name of the device, which generally is based on the | |
4640 X display or TTY file name), `device-type' (X, TTY, or stream), | |
4641 `device-class' (color, grayscale, or mono), etc. See the Lisp | |
4642 Reference Manual. | |
4643 | |
4644 Many functions have been extended to contain an additional, optional | |
4645 device argument, where such an extension makes sense. In general, if | |
4646 the argument is omitted, it is equivalent to specifying | |
4647 `(selected-device)'. | |
4648 | |
4649 Many previous functions and variables are obsoleted in favor of the | |
4650 device API. For example, `window-system' is obsoleted by | |
4651 `device-type', and `x-color-display-p' and friends are obsoleted by | |
4652 `device-class'. | |
4653 | |
4654 *** NOTE **: The obsolete variable `window-system' is going | |
4655 to be deleted soon, probably in 19.14. Please correct all | |
4656 your code to use `device-type'. | |
4657 | |
4658 *** INCOMPATIBLE CHANGE **: The function `x-display-visual-class' | |
4659 returns different values from previous versions of XEmacs. | |
4660 | |
4661 | |
4662 | |
4663 *** Errors, Warnings, C-g | |
4664 ------------------------- | |
4665 | |
4666 There is a new warnings system implemented. Many warnings that were | |
4667 formerly displayed in various ad-hoc ways (e.g. warnings about screwy | |
4668 modifier mappings, messages about failures handling the mouse cursor | |
4669 and errors in a gc-hook) have been regularized through this system. | |
4670 The new function `warn' displays a warning before the next redisplay | |
4671 (the actually display of the warning messages is accomplished through | |
4672 `display-warning-buffer'). Both `warn' and `display-warning-buffer' | |
4673 are Lisp functions (the C code calls out to them as necessary), and | |
4674 thus you can customize the warning system. | |
4675 | |
4676 Under an X display, you can press Shift-Control-G to force a "critical | |
4677 quit". This will immediately display a backtrace and pop you into the | |
4678 debugger, regardless of the settings of `inhibit-quit' and | |
4679 `debug-on-quit'. | |
4680 | |
4681 C-g now works properly even on systems that don't implement SIGIO or | |
4682 for which SIGIO is broken (e.g. IRIX 5.3 and older versions of Linux). | |
4683 In addition, the SIGIO support has been fixed for many systems on | |
4684 which it didn't always work properly before (e.g. HPUX and Solaris). | |
4685 | |
4686 | |
4687 | |
4688 *** Events | |
4689 ---------- | |
4690 | |
4691 *** INCOMPATIBLE CHANGE **: Many event functions have been changed to | |
4692 accept and return windows instead of frames. | |
4693 | |
4694 New function: `event-live-p', specifying whether `deallocate-event' | |
4695 has been called on an event. | |
4696 | |
4697 The "menu event" type has been renamed to "misc-user event", and | |
4698 encompasses scrollbar events as well as menu events. We are planning | |
4699 on making it also encompass toolbar events in a future release. | |
4700 | |
4701 New functions are provided for determining whether an particular | |
4702 sections of a frame: `event-over-border-p', `event-over-glyph-p', | |
4703 `event-over-modeline-p', `event-over-text-area-p', and | |
4704 `event-over-toolbar-p'. The old, kludgey methods of checking the | |
4705 window-height, the internal-border-width, etc. are unreliable and | |
4706 should not be used. | |
4707 | |
4708 New functions `event-window-x-pixel' and `event-window-y-pixel' are | |
4709 provided for determining where in a particular window an event | |
4710 happened. | |
4711 | |
4712 New functions `event-glyph-x-pixel' and `event-glyph-y-pixel' are | |
4713 provided for determining where in a particular glyph an event | |
4714 happened. | |
4715 | |
4716 New function `event-closest-point', which returns the closest buffer | |
4717 position to the event even if the event did not occur over any text. | |
4718 | |
4719 New variable `unread-command-events', superseding the older | |
4720 `unread-command-event'. | |
4721 | |
4722 Many event-loop bugs have been fixed. | |
4723 | |
4724 | |
4725 | |
4726 *** Extents | |
4727 ----------- | |
4728 | |
4729 The extent code has been largely rewritten. It should be faster and | |
4730 more reliable. | |
4731 | |
4732 The text-property implementation has been greatly improved. | |
4733 | |
4734 Some new extent primitives are provided to return the position of the | |
4735 next or previous property change in a buffer. | |
4736 | |
4737 Extents can now have a parent specified; then all of its properties | |
4738 (except for the buffer it's in and its position in that buffer) come | |
4739 from that extent. Hierarchies of such extents can be created. | |
4740 | |
4741 Extents now have a `detachable' property that controls what happens | |
4742 (they either get detached or shrink down to zero-length) when their | |
4743 text is deleted. Previously, such extents would always be detached. | |
4744 | |
4745 The `invisible' property on extents now works. | |
4746 | |
4747 `map-extents' has three additional parameters that provide more | |
4748 control over which extents are mapped. | |
4749 | |
4750 `map-extents' deals better with changes made to extents in the | |
4751 buffer being mapped over. | |
4752 | |
4753 A new function `mapcar-extents' (an alternative to `map-extents') has | |
4754 been provided and should be easier to use than `map-extents'. | |
4755 | |
4756 | |
4757 | |
4758 *** Faces | |
4759 --------- | |
4760 | |
4761 Faces can now be buffer-local, window-local, and device-local as well | |
4762 as frame-local, and can be further restricted to a particular device | |
4763 type or class. The way in which faces can be controlled is now based | |
4764 on the general and powerful specifier mechanism; see above. | |
4765 | |
4766 The new function `set-face-property' generalizes `set-face-font', | |
4767 `set-face-foreground', etc. and takes many new optional arguments, in | |
4768 accordance with the new specifier mechanism. | |
4769 | |
4770 The new functions `face-property' and `face-property-instance' | |
4771 generalize `face-font', `face-foreground', etc. and take many new | |
4772 optional arguments, in accordance with the new specifier mechanism. | |
4773 (`face-property' returns the value, if any, that was specified for a | |
4774 particular locale, and `face-property-instance' returns the actual | |
4775 value that will be used for display. See the section on specifiers.) | |
4776 | |
4777 The functions `face-font', `face-foreground', `face-background', | |
4778 `set-face-font', `set-face-foreground', `set-face-background', | |
4779 etc. are now convenience functions, trivially implemented using | |
4780 `face-property' and `set-face-property' and take new optioanl | |
4781 arguments in accordance with those functions. New convenience | |
4782 functions `face-font-instance', `face-foreground-instance', | |
4783 `face-background-instance', etc. are provided and are trivially | |
4784 implemented using `face-property-instance'. | |
4785 | |
4786 Inheritance of face properties can now be specified. Each individual | |
4787 face property can inherit differently from other properties, or not | |
4788 inherit at all. | |
4789 | |
4790 You can set user-defined properties on faces using | |
4791 `set-face-property'. | |
4792 | |
4793 You can create "temporary" faces, which are faces that disappear | |
4794 when they are no longer in use. This is as opposed to normal | |
4795 faces, which stay around forever. | |
4796 | |
4797 The function `make-face' takes a new optional argument specifying | |
4798 whether a face should be permanent or temporary, and returns the | |
4799 actual face object rather than the face symbol, as in previous | |
4800 versions of XEmacs. | |
4801 | |
4802 The function `face-list' takes a new optional argument specifying | |
4803 whether permanent, temporary, or both kinds of faces should be | |
4804 returned. | |
4805 | |
4806 Faces have new TTY-specific properties: `highlight', `reverse', | |
4807 `alternate', `blinking', and `dim'. | |
4808 | |
4809 Redisplay is smarter about dealing with face changes: changes to a | |
4810 particular face no longer cause all frames to be cleared and | |
4811 redisplayed. | |
4812 | |
4813 The Edit-Faces package is provided for interactively changing faces. | |
4814 A menu item on the options menu is provided for this. | |
4815 | |
4816 New functions are provided for retrieving the ascent, descent, height, | |
4817 and width of a character in a particular face. | |
4818 | |
4819 | |
4820 | |
4821 *** Fonts, Colors | |
4822 ----------------- | |
4823 | |
4824 *** INCOMPATIBLE CHANGE **: The old "font" and "pixel" objects are gone. | |
4825 In place are new objects "font specifier", "font instance", "color | |
4826 specifier", and "color instance". Functions `font-name', `pixel-name' | |
4827 (an obsolete alias for `color-name'), etc. are now convenience | |
4828 functions for working with font and color specifiers. Old code that | |
4829 is not too sophisticated about working with font and pixel objects may | |
4830 still work, though. (For example, the idiom `(font-name (face-font | |
4831 'default))' still works.) | |
4832 | |
4833 You can now extract the RGB components of a color-instance object | |
4834 (similar to the old pixel object) with the function | |
4835 `color-instance-rgb-components'. There is also a convenience function | |
4836 `color-rgb-components' for working with color specifiers. | |
4837 | |
4838 If there are no more colors available in the colormap, the nearest | |
4839 existing color will be used when allocating a new color. | |
4840 | |
4841 | |
4842 | |
4843 *** Frames | |
4844 ---------- | |
4845 | |
4846 What used to be called "screens" are now called "frames", for clarity | |
4847 and consistency with GNU Emacs. Aliases are provided for all the old | |
4848 screen functions and variables, to avoid introducing a huge E-Lisp | |
4849 incompatibility. | |
4850 | |
4851 The frame code has been merged with GNU Emacs 19.28, providing | |
4852 improved functionality for many functions. | |
4853 | |
4854 | |
4855 | |
4856 *** Glyphs, Images, and Pixmaps | |
4857 ------------------------------- | |
4858 | |
4859 Glyphs (used in various places, i.e. as begin-glyphs and end-glyphs | |
4860 attached to extents and appearing in a buffer or in marginal | |
4861 annotations; as the truncator and continuor glyphs marking line wrap | |
4862 or truncation; as an overlay at the beginning of a line; as the | |
4863 displayable element in a toolbar button; etc.) can now be | |
4864 buffer-local, window-local, frame-local, and device-local, and can be | |
4865 further restricted to a particular device type or class. The way in | |
4866 which faces can be controlled is now based on the general and powerful | |
4867 specifier mechanism; see above. | |
4868 | |
4869 *** INCOMPATIBLE CHANGE **: The glyph and pixmap API has been completely | |
4870 overhauled. A new Lisp object "glyph" is provided and should be used | |
4871 where the old "pixmap" object would have been used. The pixmap object | |
4872 exists no longer. There are also new Lisp objects "image specifier" | |
4873 and "image instance" (an image-instance is the closest equivalent to | |
4874 what a pixmap object was). More work on glyphs and images is slated | |
4875 for 19.13. The glyph and image docs in the Lisp Reference Manual are | |
4876 incomplete and will be finished in 19.13. | |
4877 | |
4878 The new function `set-glyph-property' allows setting of all the | |
4879 glyph properties (`baseline', `contrib-p', etc.). Convenience | |
4880 functions for particular properties are also provided, just like | |
4881 for faces. | |
4882 | |
4883 You can set user-defined properties on glyphs using the new function | |
4884 `set-glyph-property'. | |
4885 | |
4886 When displaying pixmaps, existing, closest-matching colors will be | |
4887 used if the colormap is full. | |
4888 | |
4889 If the compface library is compiled into XEmacs, there is built-in | |
4890 support for displaying X-Face bitmaps. (These are typically small | |
4891 pictures of people's faces, included in a mail message through the | |
4892 X-Face: header.) VM and highlight-headers will automatically use the | |
4893 built-in X-Face support if it is available. | |
4894 | |
4895 Annotations in the right margin (as well as the left margin) are now | |
4896 implemented. The left and right margin width functions have been | |
4897 superseded by the specifier variables `left-margin-width' and | |
4898 `right-margin-width', allowing much more flexible control through the | |
4899 specifier mechanism. | |
4900 | |
4901 *** INCOMPATIBLE CHANGE **: The variable `use-left-overflow', | |
4902 for controlling annotations in the left margin, is now a specifier | |
4903 variable instead of a buffer-local variable. (There is also a new | |
4904 variable `use-right-overflow', that is complementary.) | |
4905 | |
4906 | |
4907 | |
4908 *** Hashing | |
4909 ----------- | |
4910 | |
4911 Two new types of weak hashtables can be created: key-weak and | |
4912 value-weak. In a key-weak hashtable, an entry remains around | |
4913 if its key is referenced elsewhere, regardless of whether this | |
4914 is also the case for the value. Value-weak hashtables are | |
4915 complementary. (This is as opposed to the traditional weak | |
4916 hashtables, where an entry remains around only if both the | |
4917 key and value are referenced elsewhere.) New functions | |
4918 `make-key-weak-hashtable' and `make-value-weak-hashtable' | |
4919 are provided for creating these hashtables. | |
4920 | |
4921 The new function `md5' is provided for performing an MD5 | |
4922 hash of an object. MD5 is a secure message digest algorithm | |
4923 developed by RSA, inc. | |
4924 | |
4925 | |
4926 | |
4927 *** Keymaps | |
4928 ----------- | |
4929 | |
4930 The GNU Emacs concept of `function-key-map' is now partially | |
4931 implemented. This allows conversion of function-key escape sequences | |
4932 such as `ESC [ 1 1 ~' into an equivalent human-readable keysym such as | |
4933 `F1'. This work will be completed in 19.14. The function-key map is | |
4934 device-local and controllable through the functions | |
4935 `device-function-key-map' and `set-device-function-key-map'. | |
4936 | |
4937 `where-is-internal' now correctly searches minor-mode keymaps, | |
4938 extent-local keymaps, etc. As a side effect of this, menu items will | |
4939 now correctly show the keyboard equivalent for commands that are | |
4940 available through a minor-mode keymap, extent-local keymap, etc. | |
4941 | |
4942 *** INCOMPATIBLE CHANGE **: The modifier key "Symbol" has | |
4943 been renamed to "Alt", for compatibility with the rest of the world. | |
4944 Keep in mind that on many keyboards, the key labelled "Alt" actually | |
4945 generates the "Meta" modifier. (On Sun keyboards, however, the key | |
4946 labelled "Alt" does indeed generate the "Alt" modifier, and the key | |
4947 labelled with a diamond generates the "Meta" modifier.) | |
4948 | |
4949 | |
4950 | |
4951 *** Mouse, Active Region | |
4952 ------------------------ | |
4953 | |
4954 The mouse internals in mouse.el have been rewritten. Hooks have been | |
4955 provided for easier customization of mouse behavior. For example, you | |
4956 can now easily specify an action to be invoked on single-click | |
4957 (i.e. down-up without appreciable motion), double-click, drag-up, etc. | |
4958 | |
4959 Some code from GNU Emacs has been ported over, generalizing some of | |
4960 the X-specific mouse stuff. | |
4961 | |
4962 *** INCOMPATIBLE CHANGE **: The function `set-mouse-position' accepts | |
4963 a window instead of a frame. | |
4964 | |
4965 New function `mouse-position' that obsoletes and is more powerful than | |
4966 `read-mouse-position'. | |
4967 | |
4968 New functions `mouse-pixel-positon' and `set-mouse-pixel-position' for | |
4969 working with pixels instead of characters. | |
4970 | |
4971 The active (Zmacs) region is now highlighted using the `zmacs-region-face' | |
4972 instead of the `primary-selection-face'; this generalizes what used | |
4973 to be X-specific. | |
4974 | |
4975 New functions `region-active-p', `region-exists-p', and `activate-region' | |
4976 provide a uniform API for dealing with the region irrespective of | |
4977 whether the variable `zmacs-regions' is set. | |
4978 | |
4979 XEmacs is now a better X citizen with respect to the primary selection: | |
4980 it does not stomp on the primary selection quite so much. This makes | |
4981 things more manageable if you set `zmacs-regions' to nil. | |
4982 | |
4983 | |
4984 | |
4985 *** Processes | |
4986 ------------- | |
4987 | |
4988 Various process race conditions and bugs have been fixed. Problems | |
4989 with process termination not getting noticed until much later (if at | |
4990 all) should be gone now, as well as problems with zombie processes | |
4991 under some systems. | |
4992 | |
4993 SOCKS support is now included. SOCKS is a package that allows hosts | |
4994 behind a firewall to gain full access to the Internet without | |
4995 requiring direct IP reachability. | |
4996 | |
4997 | |
4998 | |
4999 *** Windows | |
5000 ----------- | |
5001 | |
5002 Windows 95 is still not out yet. | |
5003 | |
5004 *** INCOMPATIBLE CHANGE **: The functions `locate-window-from-coordinates' | |
5005 and `window-edges' have been eliminated. It no longer makes sense to | |
5006 work with windows in terms of character positions, because windows can | |
5007 (and often do) have many differently-sized fonts in them, because the | |
5008 3-D modeline is not exactly one line high, etc. | |
5009 | |
5010 The new functions `window-pixel-edges', `window-highest-p', | |
5011 `window-lowest-p', `frame-highest-window', and `frame-lowest-window' | |
5012 are provided as substitutes for the above-mentioned, deleted | |
5013 functions. | |
5014 | |
5015 The function `window-end' now takes an optional GUARANTEE argument | |
5016 that will ensure that the value is actually correct as of the next | |
5017 redisplay. | |
5018 | |
5019 The window code has been merged with GNU Emacs 19.28, providing | |
5020 improved functionality for many functions. | |
5021 | |
5022 | |
5023 | |
5024 *** System-Specific Information | |
5025 ------------------------------- | |
5026 | |
5027 Georg Nikodym's dynodump package is provided, for proper unexec()ing | |
5028 on Solaris systems. Executables built on Solaris 2.3 can now run on | |
5029 Solaris 2.4 without crashing; similarly with executables built on one | |
5030 type of Sun machine and run on another. | |
5031 | |
5032 AIX 4.x is supported. | |
5033 | |
5034 The NeXTstep operating system is supported in TTY mode (this is still | |
5035 in beta). There are plans to port XEmacs to the NeXTstep window | |
5036 system, but it may be awhile before this is complete. | |
5037 | |
5038 Problems with the `round' function causing arithmetic errors on HPUX 9 | |
5039 have been fixed. | |
5040 | |
5041 You can now build XEmacs as an ELF executable on Linux systems that | |
5042 support ELF. | |
5043 | |
5044 Various other new system configurations are supported. | |
5045 | |

5049 ** Major Differences Between 19.10 and 19.11 | |
5050 ============================================ | |
5051 | |
5052 The name has changed from "Lucid Emacs" to "XEmacs". Along with this is a | |
5053 new canonical ftp site: cs.uiuc.edu:/pub/xemacs. | |
5054 | |
5055 XEmacs now has its very own World Wide Web page! It contains a | |
5056 complete list of the FTP distribution sites, the most recent FAQ, | |
5057 pointers to Emacs Lisp packages not included with the distribution, and | |
5058 other useful stuff. Check it out at http://xemacs.cs.uiuc.edu/. | |
5059 | |
5060 A preliminary New Users Guide. | |
5061 | |
5062 cc-mode.el now provides the default C, C++ and Objective-C modes. | |
5063 | |
5064 The primary goal of this release is stability. Very few new features have | |
5065 been introduced but lots of bugs have been fixed. Many of the Emacs Lisp | |
5066 packages have been updated. | |
5067 | |
5068 Some of the new Emacs Lisp packages --- | |
5069 | |
5070 tcl-mode.el: major mode for editing TCL code | |
5071 | |
5072 fast-lock.el: saves and restores font-lock highlighting, greatly | |
5073 reducing the time necessary for loading a font-lock'ed | |
5074 file | |
5075 | |
5076 ps-print.el: prints buffers to Postscript printers preserving the | |
5077 buffer's bold and italic text attributes | |
5078 | |
5079 toolbar.el: provides a "fake" toolbar for use with XEmacs (an | |
5080 integrated one will be included with 19.12) | |
5081 | |
5082 | |
5083 ** Major Differences Between 19.9 and 19.10 | |
5084 =========================================== | |
5085 | |
5086 The GNU `configure' system is now used to build lemacs. | |
5087 | |
5088 The Emacs Manual and Emacs Lisp Reference Manual now document version 19.10. | |
5089 If you notice any errors, please let us know. | |
5090 | |
5091 When pixmaps are displayed in a buffer, they contribute to the line height - | |
5092 that is, if the glyph is taller than the rest of the text on the line, the | |
5093 line will be as tall as necessary to display the glyph. | |
5094 | |
5095 In addition to using arbitrary sound files as emacs beeps, one can control | |
5096 the pitch and duration of the standard X beep, on X servers which allow that | |
5097 (Note: most don't.) | |
5098 | |
5099 There is support for playing sounds on systems with NetAudio servers. | |
5100 | |
5101 Minor modes may have mode-specific key bindings; keymaps may have an arbitrary | |
5102 number of parent maps. | |
5103 | |
5104 Menus can have toggle and radio buttons in them. | |
5105 | |
5106 There is a font selection menu. | |
5107 | |
5108 Some default key bindings have changed to match FSF19; the new bindings are | |
5109 | |
5110 Screen-related commands: | |
5111 C-x 5 2 make-screen | |
5112 C-x 5 0 delete-screen | |
5113 C-x 5 b switch-to-buffer-other-screen | |
5114 C-x 5 f find-file-other-screen | |
5115 C-x 5 C-f find-file-other-screen | |
5116 C-x 5 m mail-other-screen | |
5117 C-x 5 o other-screen | |
5118 C-x 5 r find-file-read-only-other-screen | |
5119 Abbrev-related commands: | |
5120 C-x a l add-mode-abbrev | |
5121 C-x a C-a add-mode-abbrev | |
5122 C-x a g add-global-abbrev | |
5123 C-x a + add-mode-abbrev | |
5124 C-x a i g inverse-add-global-abbrev | |
5125 C-x a i l inverse-add-mode-abbrev | |
5126 C-x a - inverse-add-global-abbrev | |
5127 C-x a e expand-abbrev | |
5128 C-x a ' expand-abbrev | |
5129 Register-related commands: | |
5130 C-x r C-SPC point-to-register | |
5131 C-x r SPC point-to-register | |
5132 C-x r j jump-to-register | |
5133 C-x r s copy-to-register | |
5134 C-x r x copy-to-register | |
5135 C-x r i insert-register | |
5136 C-x r g insert-register | |
5137 C-x r r copy-rectangle-to-register | |
5138 C-x r c clear-rectangle | |
5139 C-x r k kill-rectangle | |
5140 C-x r y yank-rectangle | |
5141 C-x r o open-rectangle | |
5142 C-x r t string-rectangle | |
5143 C-x r w window-configuration-to-register | |
5144 Narrowing-related commands: | |
5145 C-x n n narrow-to-region | |
5146 C-x n w widen | |
5147 Other changes: | |
5148 C-x 3 split-window-horizontally (was undefined) | |
5149 C-x - shrink-window-if-larger-than-buffer | |
5150 C-x + balance-windows | |
5151 | |
5152 The variable allow-deletion-of-last-visible-screen has been removed, since | |
5153 it was widely hated. You can now always delete the last visible screen if | |
5154 there are other iconified screens in existence. | |
5155 | |
5156 ToolTalk support is provided. | |
5157 | |
5158 An Emacs screen can be placed within an "external client widget" managed | |
5159 by another application. This allows an application to use an Emacs screen | |
5160 as its text pane rather than the standard Text widget that is provided | |
5161 with Motif or Athena. | |
5162 | |
5163 Additional compatibility with Epoch is provided (though this is not yet | |
5164 complete.) | |
5165 | |
5166 | |
5167 ** Major Differences Between 19.8 and 19.9 | |
5168 ========================================== | |
5169 | |
5170 Scrollbars! If you have Motif, these are real Motif scrollbars; otherwise, | |
5171 Athena scrollbars are used. They obey all the usual resources of their | |
5172 respective toolkits. | |
5173 | |
5174 There is now an implementation of dialog boxes based on the Athena | |
5175 widgets, as well as the existing Motif implementation. | |
5176 | |
5177 This release works with Motif 1.2 as well as 1.1. If you link with Motif, | |
5178 you do not also need to link with Athena. | |
5179 | |
5180 If you compile lwlib with both USE_MOTIF and USE_LUCID defined (which is the | |
5181 recommended configuration) then the Lucid menus will draw text using the Motif | |
5182 string-drawing library, instead of the Xlib one. The reason for this is that | |
5183 one can take advantage of the XmString facilities for including non-Latin1 | |
5184 characters in resource specifications. However, this is a user-visible change | |
5185 in that, in this configuration, the menubar will use the "*fontList" resource | |
5186 in preference to the "*font" resource, if it is set. | |
5187 | |
5188 It's possible to make extents which are copied/pasted by kill and undo. | |
5189 There is an implementation of FSF19-style text properties based on this. | |
5190 | |
5191 There is a new variable, minibuffer-max-depth, which is intended to circumvent | |
5192 a common source of confusion among new Emacs users. Since, under a window | |
5193 system, it's easy to jump out of the minibuffer (by doing M-x, then getting | |
5194 distracted, and clicking elsewhere) many, many novice users have had the | |
5195 problem of having multiple minibuffers build up, even to the point of | |
5196 exhausting the lisp stack. So the default behavior is to disallow the | |
5197 minibuffer to ever be reinvoked while active; if you attempt to do so, you | |
5198 will be prompted about it. | |
5199 | |
5200 There is a new variable, teach-extended-commands-p, which if set, will cause | |
5201 `M-x' to remind you of any key bindings of the command you just invoked the | |
5202 "long way." | |
5203 | |
5204 There are menus in Dired, Tar, Comint, Compile, and Grep modes. | |
5205 | |
5206 There is a menu of window management commands on the right mouse button over | |
5207 the modelines. | |
5208 | |
5209 Popup menus now have titles at the top; this is controlled by the new | |
5210 variable `popup-menu-titles'. | |
5211 | |
5212 The `Find' key on Sun keyboards will search for the next (or previous) | |
5213 occurrence of the selected text, as in OpenWindows programs. | |
5214 | |
5215 The `timer' package has been renamed to `itimer' to avoid a conflict with | |
5216 a different package called `timer'. | |
5217 | |
5218 VM 5.40 is included. | |
5219 | |
5220 W3, the emacs interface to the World Wide Web, is included. | |
5221 | |
5222 Felix Lee's GNUS speedups have been installed, including his new version of | |
5223 nntp.el which makes GNUS efficiently utilize the NNTP XOVER command if | |
5224 available (which is much faster.) | |
5225 | |
5226 GNUS should also be much friendlier to new users: it starts up much faster, | |
5227 and doesn't (necessarily) subscribe you to every single newsgroup. | |
5228 | |
5229 The byte-compiler issues a new class of warnings: variables which are | |
5230 bound but not used. This is merely an advisory, and does not mean the | |
5231 code is incorrect; you can disable these warnings in the usual way with | |
5232 the `byte-compiler-options' macro. | |
5233 | |
5234 the `start-open' and `end-open' extent properties, for specifying whether | |
5235 characters inserted exactly at a boundary of an extent should go into the | |
5236 extent or out of it, now work correctly. | |
5237 | |
5238 The `extent-data' slot has been generalized/replaced with a property list, | |
5239 so it's easier to attach arbitrary data to extent objects. | |
5240 | |
5241 The `event-modifiers' and `event-modifier-bits' functions work on motion | |
5242 events as well as other mouse and keyboard events. | |
5243 | |
5244 Forms-mode uses fonts and read-only regions. | |
5245 | |
5246 The behavior of the -geometry command line option should be correct now. | |
5247 | |
5248 The `iconic' screen parameter works when passed to x-create-screen. | |
5249 | |
5250 The user's manual now documents Lucid Emacs 19.9. | |
5251 | |
5252 The relocating buffer allocator is turned on by default; this means that when | |
5253 buffers are killed, their storage will be returned to the operating system, | |
5254 and the size of the emacs process will shrink. | |
5255 | |
5256 CAVEAT: code which contains calls to certain `face' accessor functions will | |
5257 need to be recompiled by version 19.9 before it will work. The functions | |
5258 whose callers must be recompiled are: face-font, face-foreground, | |
5259 face-background, face-background-pixmap, and face-underline-p. The symptom | |
5260 of this problem is the error "Wrong type argument, arrayp, #<face ... >". | |
5261 The .elc files generated by version 19.9 will work in 19.6 and 19.8, but | |
5262 older .elc files which contain calls to these functions will not work in 19.9. | |
5263 | |
5264 Work In Progress: | |
5265 | |
5266 - We have been in the process of internationalizing Lucid Emacs. This code is | |
5267 ***not*** ready for general use yet. However, the code is included (and | |
5268 turned off by default) in this release. | |
5269 | |
5270 - If you define I18N2 at compile-time, then sorting/collation will be done | |
5271 according to the locale returned by setlocale(). | |
5272 | |
5273 - If you define I18N3 at compile-time, then all messages printed by lemacs | |
5274 will be filtered through the gettext() library routine, to enable the use | |
5275 of locale-specific translation catalogues. The current implementation of | |
5276 this is quite dependent on Solaris 2, and has a very large impact on | |
5277 existing code, therefore we are going to be making major changes soon. | |
5278 (You'll notice calls to `gettext' and `GETTEXT' scattered around much of | |
5279 the lisp and C code; ignore it, this will be going away.) | |
5280 | |
5281 - If you define I18N4 at compile-time, then lemacs will internally use a | |
5282 wide representation of characters, enabling the use of large character | |
5283 sets such as Kanji. This code is very OS dependent: it requires X11R5, | |
5284 and several OS-supplied library routines for reading and writing wide | |
5285 characters (getwc(), putwc(), and a few others.) Performance is also a | |
5286 problem. This code is also scheduled for a major overhaul, with the | |
5287 intent of improving performance and portability. | |
5288 | |
5289 Our eventual goal is to merge with MULE, or at least provide the same base | |
5290 level of functionality. If you would like to help out with this, let us | |
5291 know. | |
5292 | |
5293 - Other work-in-progress includes Motif drag-and-drop support, ToolTalk | |
5294 support, and support for embedding an Emacs widget inside another | |
5295 application (where it can function as that other application's text-entry | |
5296 area). This code has not been extensively tested, and may (or may not) | |
5297 have portability problems, but it's there for the adventurous. Comments, | |
5298 suggestions, bug reports, and especially fixes are welcome. But have no | |
5299 expectations that this experimental code will work at all. | |
5300 | |
5301 | |
5302 ** Major Differences Between 19.6 and 19.8 | |
5303 ========================================== | |
5304 | |
5305 There were almost no differences between versions 19.6 and 19.7; version 19.7 | |
5306 was a bug-fix release that was distributed with Energize 2.1. | |
5307 | |
5308 Lucid Emacs 19.8 represents the first stage of the Lucid Emacs/Epoch merger. | |
5309 The redisplay engine now in lemacs is an improved descendant of the Epoch | |
5310 redisplay. As a result, many bugs have been eliminated, and several disabled | |
5311 features have been re-enabled. Notably: | |
5312 | |
5313 Selective display (and outline-mode) work. | |
5314 | |
5315 Horizontally split windows work. | |
5316 | |
5317 The height of a line is the height of the tallest font displayed on that line; | |
5318 it is possible for a screen to display lines of differing heights. (Previously, | |
5319 the height of all lines was the height of the tallest font loaded.) | |
5320 | |
5321 There is lisp code to scale fonts up and down, for example, to load the next- | |
5322 taller version of a font. | |
5323 | |
5324 There is a new internal representation for lisp objects, giving emacs-lisp 28 | |
5325 bit integers and a 28 bit address space, up from the previous maximum of 26. | |
5326 We expect eventually to increase this to 30 bit integers and a 32 bit address | |
5327 space, eliminating the need for DATA_SEG_BITS on some architectures. (On 64 | |
5328 bit machines, add 32 to all of these numbers.) | |
5329 | |
5330 GC performance is improved. | |
5331 | |
5332 Various X objects (fonts, colors, cursors, pixmaps) are accessible as first- | |
5333 class lisp objects, with finalization. | |
5334 | |
5335 An alternate interface to embedding images in the text is provided, called | |
5336 "annotations." You may create an "annotation margin" which is whitespace at | |
5337 the left side of the screen that contains only annotations, not buffer text. | |
5338 | |
5339 When using XPM files, one can specify the values of logical color names to be | |
5340 used when loading the files. | |
5341 | |
5342 It is possible to resize windows by dragging their modelines up and down. More | |
5343 generally, it is possible to add bindings for mouse gestures on the modelines. | |
5344 | |
5345 There is support for playing sound files on HP machines. | |
5346 | |
5347 ILISP version 5.5 is included. | |
5348 | |
5349 The Common Lisp #' read syntax is supported (#' is to "function" as ' is to | |
5350 "quote".) | |
5351 | |
5352 The `active-p' slot of menu items is now evaluated, so one can put arbitrary | |
5353 lisp code in a menu to decide whether that item should be selectable, rather | |
5354 than doing this with an `activate-menubar-hook'. | |
5355 | |
5356 The X resource hierarchy has changed slightly, to be more consistent. It used | |
5357 to be | |
5358 argv[0] SCREEN-NAME pane screen | |
5359 ApplicationShell EmacsShell Paned EmacsFrame | |
5360 | |
5361 now it is | |
5362 | |
5363 argv[0] shell pane SCREEN-NAME | |
5364 ApplicationShell EmacsShell Paned EmacsFrame | |
5365 | |
5366 The Lucid Emacs sources have been largely merged with FSF version 19; this | |
5367 means that the lisp library contains the most recent releases of various | |
5368 packages, and many new features of FSF 19 have been incorporated. | |
5369 | |
5370 Because of this, the lemacs sources should also be substantially more portable. | |
5371 | |
5372 | |
5373 ** Major Differences Between 19.4 and 19.6 | |
5374 ========================================== | |
5375 | |
5376 There were almost no differences between versions 19.4 and 19.5; we fixed | |
5377 a few minor bugs and repacked 19.4 as 19.5 for a CD-ROM that we gave away | |
5378 as a trade show promotion. | |
5379 | |
5380 The primary goal of the 19.6 release is stability, rather than improved | |
5381 functionality, so there aren't many user-visible changes. The most notable | |
5382 changes are: | |
5383 | |
5384 - The -geometry command-line option now correctly overrides geometry | |
5385 specifications in the resource database. | |
5386 - The `width' and `height' screen-parameters work. | |
5387 - Font-lock-mode considers the comment start and end characters to be | |
5388 a part of the comment. | |
5389 - The lhilit package has been removed. Use font-lock-mode instead. | |
5390 - vm-isearch has been fixed to work with isearch-mode. | |
5391 - new versions of ispell and calendar. | |
5392 - sccs.el has menus. | |
5393 | |
5394 Lots of bugs were fixed, including the problem that lemacs occasionally | |
5395 grabbed the keyboard focus. | |
5396 | |
5397 Also, as of Lucid Emacs 19.6 and Energize 2.0 (shipping now) it is possible | |
5398 to compile the public release of Lucid Emacs with support for Energize; so | |
5399 now Energize users will be able to build their own Energize-aware versions | |
5400 of lemacs, and will be able to use newer versions of lemacs as they are | |
5401 released to the net. (Of course, this is not behavior covered by your | |
5402 Energize support contract; you do it at your own risk.) | |
5403 | |
5404 I have not incorporated all portability patches that I have been sent since | |
5405 19.4; I will try to get to them soon. However, if you need to make any | |
5406 changes to lemacs to get it to compile on your system, it would be quite | |
5407 helpful if you would send me context diffs (diff -c) against version 19.6. | |
5408 | |
5409 | |
5410 ** Major Differences Between 19.3 and 19.4 | |
5411 ========================================== | |
5412 | |
5413 Prototypes have been added for all functions. Emacs compiles in the strict | |
5414 ANSI modes of lcc and gcc, so portability should be vastly improved. | |
5415 | |
5416 Many many many many core leaks have been plugged, especially in screen | |
5417 creation and deletion. | |
5418 | |
5419 The float support reworked to be more portable and ANSI conformant. This | |
5420 resulted in these new configuration parameters: HAVE_INVERSE_HYPERBOLIC, | |
5421 HAVE_CBRT, HAVE_RINT, FLOAT_CHECK_ERRNO, FLOAT_CATCH_SIGILL, | |
5422 FLOAT_CHECK_DOMAIN. Let us know if you had to change the defaults on your | |
5423 architecture. | |
5424 | |
5425 The SunOS unexec has been rewritten, and now works with either static or | |
5426 dynamic libraries, depending on whether -Bstatic or -Bdynamic were specified | |
5427 at link-time. | |
5428 | |
5429 Small (character-sized) bitmaps can be mixed in with buffer text via the new | |
5430 functions set-extent-begin-glyph and set-extent-end-glyph. (This is actually | |
5431 a piece of functionality that Energize has been using for a while, but we've | |
5432 just gotten around to making it possible to use it without Energize. See how | |
5433 nice we are? Go buy our product.) | |
5434 | |
5435 If compiled with Motif support, one can pop up dialog boxes from emacs lisp. | |
5436 We encourage someone to contribute Athena an version of this code; it | |
5437 shouldn't be much work. | |
5438 | |
5439 If dialog boxes are available, then y-or-n-p and yes-or-no-p use dialog boxes | |
5440 instead of the minibuffer if invoked as a result of a command that was | |
5441 executed from a menu instead of from the keyboard. | |
5442 | |
5443 Multiple screen support works better; check out doc of get-screen-for-buffer. | |
5444 | |
5445 The default binding of backspace is the same as delete. (C-h is still help.) | |
5446 | |
5447 A middle click while the minibuffer is active does completion if you click on | |
5448 a highlighted completion, otherwise it executes the global binding of button2. | |
5449 | |
5450 New versions of Barry Warsaw's c++-mode and syntax.c. Font-lock-mode works | |
5451 with C++ mode now. | |
5452 | |
5453 The semantics of activate-menubar-hook has changed; the functions are called | |
5454 with no arguments now. | |
5455 | |
5456 `truename' no longer hacks the automounter; use directory-abbrev-alist instead. | |
5457 | |
5458 Most minibuffer handling has been reimplemented in emacs-lisp. | |
5459 | |
5460 There is now a builtin minibuffer history mechanism which replaces gmhist. | |
5461 | |
5462 | |
5463 ** Major Differences Between 19.2 and 19.3 | |
5464 ========================================== | |
5465 | |
5466 The ISO characters have correct case and syntax tables now, so the word-motion | |
5467 and case-converting commands work sensibly on them. | |
5468 | |
5469 If you set ctl-arrow to an integer, you can control exactly which characters | |
5470 are printable. (There will be a less crufty way to do this eventually.) | |
5471 | |
5472 Menubars can now be buffer local; the function set-screen-menubar no longer | |
5473 exists. Look at GNUS and VM for examples of how to do this, or read | |
5474 menubar.el. | |
5475 | |
5476 When emacs is reading from the minibuffer with completions, any completions | |
5477 which are visible on the screen will highlight when the mouse moves over them; | |
5478 clicking middle on a completion is the same as typing it at the minibuffer. | |
5479 Some implications of this: The *Completions* buffer is always mousable. If | |
5480 you're using the completion feature of find-tag, your source code will be | |
5481 mousable when you type M-. Dired buffers will be mousable as soon as you | |
5482 type ^X^F. And so on. | |
5483 | |
5484 The old isearch code has been replaced with a descendant of Dan LaLiberte's | |
5485 excellent isearch-mode; it is more customizable, and generally less bogus. | |
5486 You can search for "composed" characters. There are new commands, too; see | |
5487 the doc for ^S, or the NEWS file. | |
5488 | |
5489 A patched GNUS 3.14 is included. | |
5490 | |
5491 The user's manual now documents Lucid Emacs 19.3. | |
5492 | |
5493 A few more modes have mouse and menu support. | |
5494 | |
5495 The startup code should be a little more robust, and give you more reasonable | |
5496 error messages when things aren't installed quite right (instead of the | |
5497 ubiquitous "cannot open DISPLAY"...) | |
5498 | |
5499 Subdirectories of the lisp directory whose names begin with a hyphen or dot | |
5500 are not automatically added to the load-path, so you can use this to avoid | |
5501 accidentally inflicting experimental software on your users. | |
5502 | |
5503 I've tried to incorporate all of the portability patches that were sent to | |
5504 me; I tried to solve some of the problems in different ways than the | |
5505 patches did, so let me know if I missed something. | |
5506 | |
5507 Some systems will need to define NEED_STRDUP, NEED_REALPATH, HAVE_DREM, or | |
5508 HAVE_REMAINDER in config.h. Really this should be done in the appropriate | |
5509 s- or m- files, but I don't know which systems need these and which don't. | |
5510 If yours does, let me know which file it should be in. | |
5511 | |
5512 Check out these new packages: | |
5513 | |
5514 blink-paren.el: causes the matching parenthesis to flash on and off whenever | |
5515 the cursor is sitting on a paren-syntax character. | |
5516 | |
5517 pending-del.el: Certain commands implicitly delete the highlighted region: | |
5518 Typing a character when there is a highlighted region replaces | |
5519 that region with the typed character. | |
5520 | |
5521 font-lock.el: A code-highlighting package, driven off of syntax tables, so | |
5522 that it understands block comments, strings, etc. The | |
5523 insertion hook is used to fontify text as you type it in. | |
5524 | |
5525 shell-font.el: Displays your shell-buffer prompt in boldface. | |
