lisp/ChangeLog addition:
2015-05-15 Aidan Kehoe <kehoea@parhasard.net>
* simple.el:
* simple.el (line-number): Moved to buffer.c; we have an existing

| 27 * Introduction | |
| 28 ============== | |
| 29 | |
| 30 This file presents some general information about XEmacs. It is primarily | |
| 31 about the evolution of XEmacs and its release history. | |
| 32 | |
| 33 There are five sections. | |
| 34 | |
| 35 Introduction................(this section) provides an introduction | |
| 36 | |
| 37 Using Outline Mode..........briefly explains how to use outline mode | |
| 38 | |
| 39 XEmacs Release Notes........detailed changes to this release | |
| 40 | |
| 41 Future Plans for XEmacs.....what's next | |
| 42 | |
| 43 The History of XEmacs.......some historical notes | |
| 44 | |
| 45 A Long List of Packages.....all the stuff in XEmacs | |
| 46 | |
| 47 What Changed................between versions and also FSF GNU Emacs | |
| 48 | |
| 49 New users should look at the next section on "Using Outline Mode". | |
| 50 You will be more efficient when you can navigate quickly through this | |
| 51 file. Users who want to know which capabilities have been introduced | |
| 52 in this release should look at the "XEmacs Release Notes." Users | |
| 53 interested in some of the details of how XEmacs differs from GNU Emacs | |
| 54 should read the section "What Changed?". | |
| 55 | |
| 56 N.B. The term "FSF GNU Emacs" refers to any release of Emacs | |
| 57 Version 19 from the Free Software Foundation's GNU Project. (We do | |
| 58 not say just "GNU Emacs" because Richard M. Stallman ["RMS"] | |
| 59 thinks that this term is too generic; although we sometimes say | |
| 60 e.g. "GNU Emacs 19.30" to refer to a specific version of FSF GNU | |
| 61 Emacs. The term "XEmacs" refers to this program or to its | |
| 62 predecessors "Era", "Epoch", and "Lucid Emacs". The predecessor | |
| 63 of all these program is called "Emacs 18". When no particular | |
| 64 version is implied, "Emacs" will be used. | |
| 65 | |
| 66 | |
| 67 * Using Outline Mode | |
| 68 ==================== | |
| 69 | |
| 70 This file is in outline mode, a major mode for viewing (or editing) | |
| 71 outlines. It allows you to make parts of the text temporarily invisible so | |
| 72 that you can see just the overall structure of the outline. | |
| 73 | |
| 74 There are two ways of using outline mode: with keys or with menus. Using | |
| 75 outline mode with menus is the simplest and is just as effective as using | |
| 76 keystrokes. There are menus for outline mode on the menubar as well as in | |
| 77 popup menus activated by pressing mouse button 3. | |
| 78 | |
| 79 Try the following to help you read this file. | |
| 80 | |
| 81 C-c C-q This hides everything but the very top level headings | |
| 82 You can then move to an interesting section | |
| 83 C-c TAB This shows subheadings (if any) of current heading. | |
| 84 C-c C-s Show _all_ the text and headings under current heading | |
| 85 C-c C-d Hide _all_ the text and headings under current heading | |
| 86 | |
| 87 It's then easy to navigate through the file alternating between | |
| 88 showing, C-C C-s, and hiding, C-c C-d, the text. Also, use the "Show" | |
| 89 and "Hide" menus displayed to get access to the same commands. | |
| 90 | |
| 91 You may at any time press `C-h m' to get a listing of the outline mode key | |
| 92 bindings. | |
| 93 | |
| 94 * XEmacs Release Notes | |

| 263 | |
| 264 ** Major Differences Between 19.14 and 19.15 | |
| 265 ============================================ | |
| 266 | |
| 267 Many bugs have been fixed. An effort has been made to eradicate all | |
| 268 XEmacs crashes, although we are not quite done yet. The overall | |
| 269 quality of XEmacs should be higher than any previous release. XEmacs | |
| 270 now compiles with nary a warning with some compilers. | |
| 271 | |
| 272 User visible changes: | |
| 273 | |
| 274 -- EFS replaces ange-ftp for remote file manipulation capability. | |
| 275 | |
| 276 -- TM (Tools for Mime) now comes with XEmacs. This provides MIME | |
| 277 (Multi-purpose Internet Multi-media Extensions?) support for Mail | |
| 278 and News. The primary author is Morioka Tomohiko. | |
| 279 | |
| 280 -- There is a new way to customize faces and (some) variables. | |
| 281 Try it with `M-x customize RET', or from the Options->Customize menu. | |
| 282 Documented in <URL:info:custom>. | |
| 283 | |
| 284 -- The AUC TeX environment for editing and running TeX is now bundled. | |
| 285 (Per Abrahamsen.) | |
| 286 Enable with (require 'tex-site) in your .emacs file. | |
| 287 Documented in <URL:info:auctex>. | |
| 288 | |
| 289 -- New user option `init-face-from-resources'. | |
| 290 If you don't set faces with X resources, you can speed up the | |
| 291 initialization of new faces by setting this to nil. | |
| 292 | |
| 293 -- `column.el' removed, use `column-number-mode' instead. | |
| 294 | |
| 295 -- Command line processing should work much better now - no more order | |
| 296 dependencies. | |
| 297 | |
| 298 -- html mode now defaults to using HTML-3.2 | |
| 299 | |
| 300 -- VM now has a native MIME mode | |
| 301 | |
| 302 -- The traditional time.el package now has optional modeline graphics | |
| 303 | |
| 304 -- The XEmacs Logo has been changed courtesy of Jens Lautenbacher | |
| 305 | |
| 306 -- Default background changed to gray80 | |
| 307 | |
| 308 -- The XEmacs build procedure has been changed to make it easier than | |
| 309 ever to include new packages to be dumped with the binary | |
| 310 | |
| 311 -- cc-mode is no longer auto-loaded. (require 'cc-mode) is now needed | |
| 312 before you customize cc-mode in your .emacs. | |
| 313 | |
| 314 -- blink-cursor-mode is somewhat more useable now that the cursor | |
| 315 stops blinking during keyboard activity. | |
| 316 | |
| 317 -- Dired is now part of efs and went from version 6.X to 7.9. | |
| 318 Keybindings have been synced with FSF Emacs, there are more menus and | |
| 319 items in menus are sometimes grouped differently. Any personnal | |
| 320 customization to dired will probably have to be checked. | |
| 321 | |
| 322 If you are a 19.14 user and use its dired a lot, expect to get mad at | |
| 323 'c', 'r' and '^' keybindings." | |
| 324 | |
| 325 | |
| 326 ** New Packages | |

| 411 **** A way to specify that "uninteresting" fields be suppressed when | |
| 412 generating lines in buffers. | |
| 413 | |
| 414 **** Several commands in the group buffer can be undone with | |
| 415 `M-C-_'. | |
| 416 | |
| 417 **** Scoring can be done on words using the new score type `w'. | |
| 418 | |
| 419 **** Adaptive scoring can be done on a Subject word-by-word basis: | |

| 476 - Much fuller stylesheet support | |
| 477 - Tables support | |
| 478 - Frames support | |
| 479 - better asynchronous downloads | |
| 480 - now uses the widget library for consistent look of form elements | |
| 481 - Much much much faster | |
| 482 *** ilisp 5.8 (Chris McConnell, Ivan Vasquez, Marco Antoniotti, Rick | |

| 508 ** Changes at Lisp level | |
| 509 ------------ | |
| 510 | |
| 511 -- New `widget' library for inserting UI components in buffers. | |
| 512 Documented in <URL:info:widget>. | |
| 513 | |
| 514 -- New `custom' library for declaring user options and faces. | |
| 515 Documented in <URL:info:custom>. | |
| 516 | |
| 517 -- New function `make-empty-face'. | |
| 518 Like `make-face', but doesn't query the resource database. | |
| 519 | |
| 520 -- New function x-keysym-on-keyboard-p helps determine keyboard | |
| 521 characteristics for key rebinding: | |
| 522 | |
| 523 x-keysym-on-keyboard-p: (KEYSYM &optional DEVICE) | |
| 524 -- a built-in function. | |
| 525 Return true if KEYSYM names a key on the keyboard of DEVICE. | |
| 526 More precisely, return true if pressing a physical key | |
| 527 on the keyboard of DEVICE without any modifier keys generates KEYSYM. | |
| 528 Valid keysyms are listed in the files /usr/include/X11/keysymdef.h and in | |
| 529 /usr/lib/X11/XKeysymDB, or whatever the equivalents are on your system. | |
| 530 | |
| 531 -- Usage of keysyms of the form kp_0 is deprecated and one should use | |
| 532 the Emacs compatible kp-0 instead. | |
| 533 | |
| 534 | |
| 535 -- preceding-char and following-char have been obsoleted. Use the | |
| 536 much safer and correct functions char-after and char-before instead. | |
| 537 | |
| 538 -- Many symbols present for compatibility with GNU Emacs no longer | |
| 539 generate bytecompiler warning messages | |
| 540 | |
| 541 -- Installed info files are now compressed (support courtesy of Joseph J Nuspl) | |
| 542 | |
| 543 -- (load-average) works on Solaris, even if you're not root. Thanks to | |
| 544 Hrvoje Niksic. | |
| 545 | |
| 546 -- OffiX drag-and-drop support added | |
| 547 | |
| 548 -- lots of syncing with 19.34 elisp files, most by Steven Baur | |
| 549 | |
| 550 -- M-: (eval-expression) is now enabled by default since it is much | |
| 551 more difficult to type. | |
| 552 | |
| 553 -- new variables: | |
| 554 signal-error-on-buffer-boundary | |
| 555 | |
| 556 | |
| 557 * Future Plans for XEmacs | |
| 558 ========================== | |
| 559 | |
| 560 This is the end of the line for XEmacs v19. No new development is planned | |
| 561 on this source tree. XEmacs 20.1 will contain the functionality in 19.15, | |
| 562 and development will continue with XEmacs 20.2. The major new `feature' | |
| 563 planned in 20.2 will be the introduction of separable packages and the | |
| 564 capability to download and use an XEmacs lite distribution. | |
| 565 | |
| 566 * The History of XEmacs | |
| 567 ======================= | |
| 568 | |
| 569 This product is an extension of GNU Emacs, previously known to some as | |
| 570 "Lucid Emacs" or "ERA". It was initially based on an early version of Emacs | |
| 571 Version 19 from the Free Software Foundation and has since been kept | |
| 572 up-to-date with recent versions of that product. It stems from a | |
| 573 collaboration of Lucid, Inc. with SunSoft DevPro (a division of Sun | |
| 574 Microsystems, Inc.; formerly called SunPro) and the University of Illinois. | |
| 575 | |
| 576 NOTE: Lucid, Inc. is currently out of business but development on XEmacs | |
| 577 continues strong. Recently, Amdahl Corporation and INS Engineering have | |
| 578 both contributed significantly to the development of XEmacs. | |
| 579 | |
| 580 | |
| 581 * A Long List of Packages | |
| 582 ======================= | |
| 583 | |
| 584 This section gives a detailed list of packages included with XEmacs. | |
| 585 It's long! Of particular interest are: games, gnus, modes, packages, | |
| 586 and utils. | |
| 587 | |
| 588 ** auctex - Super TeX | |
| 589 *** auctex/auc-old.el | |
| 590 This file contains an alternative keymapping, compatible with | |
| 591 older versions of AUC TeX. You are strongly suggested to try the | |
| 592 new keyboard layout, as we would like this file to go away | |
| 593 eventually. | |
| 594 *** auctex/bib-cite.el | |
| 595 Commentary: | |
| 596 | |
| 597 This package is used in various TeX modes to display or edit references | |
| 598 associated with \cite commands, or matching \ref and \label commands. | |
| 599 *** auctex/font-latex.el | |
| 600 Commentary: | |
| 601 *** auctex/style/german.el | |
| 602 Commentary: | |
| 603 | |
| 604 `german.sty' use `"' to give next character an umlaut. | |
| 605 *** auctex/style/harvard.el | |
| 606 Commentary: | |
| 607 | |
| 608 Harvard citation style is from Peter Williams available on the CTAN | |
| 609 servers | |
| 610 *** auctex/style/plfonts.el | |
| 611 Commentary: | |
| 612 | |
| 613 `plfonts.sty' use `"' to make next character Polish. | |
| 614 `plfonts.sty' <C> L. Holenderski, IIUW, lhol@mimuw.edu.pl | |
| 615 *** auctex/style/plhb.el | |
| 616 Commentary: | |
| 617 | |
| 618 `plhb.sty' use `"' to make next character Polish. | |
| 619 `plhb.sty' <C> J. S. Bie\'n, IIUW, jsbien@mimuw.edu.pl | |
| 620 | |
| 621 | |
| 622 ** bytecomp - Byte compile Emacs Lisp files | |
| 623 *** bytecomp/byte-optimize.el | |
| 624 Commentary: | |
| 625 | |
| 626 ======================================================================== | |
| 627 "No matter how hard you try, you can't make a racehorse out of a pig. | |
| 628 You can, however, make a faster pig." | |
| 629 | |
| 630 Or, to put it another way, the emacs byte compiler is a VW Bug. This code | |
| 631 makes it be a VW Bug with fuel injection and a turbocharger... You're | |
| 632 still not going to make it go faster than 70 mph, but it might be easier | |
| 633 to get it there. | |
| 634 | |
| 635 *** bytecomp/bytecomp-runtime.el | |
| 636 Commentary: | |
| 637 | |
| 638 interface to selectively inlining functions. | |
| 639 This only happens when source-code optimization is turned on. | |
| 640 *** bytecomp/bytecomp.el | |
| 641 Commentary: | |
| 642 | |
| 643 The Emacs Lisp byte compiler. This crunches lisp source into a sort | |
| 644 of p-code which takes up less space and can be interpreted faster. | |
| 645 The user entry points are byte-compile-file and byte-recompile-directory. | |
| 646 *** bytecomp/disass.el | |
| 647 Commentary: | |
| 648 | |
| 649 The single entry point, `disassemble', disassembles a code object generated | |
| 650 by the Emacs Lisp byte-compiler. This doesn't invert the compilation | |
| 651 operation, not by a long shot, but it's useful for debugging. | |
| 652 | |
| 653 ** calendar - Calendars, diaries and appointments | |
| 654 *** calendar/calendar.el | |
| 655 Commentary: | |
| 656 | |
| 657 This collection of functions implements a calendar window. It | |
| 658 generates a calendar for the current month, together with the previous | |
| 659 and coming months, or for any other three-month period. The calendar | |
| 660 can be scrolled forward and backward in the window to show months in | |
| 661 the past or future; the cursor can move forward and backward by days, | |
| 662 weeks, or months, making it possible, for instance, to jump to the | |
| 663 date a specified number of days, weeks, or months from the date under | |
| 664 the cursor. The user can display a list of holidays and other notable | |
| 665 days for the period shown; the notable days can be marked on the | |
| 666 calendar, if desired. The user can also specify that dates having | |
| 667 corresponding diary entries (in a file that the user specifies) be | |
| 668 marked; the diary entries for any date can be viewed in a separate | |
| 669 window. The diary and the notable days can be viewed independently of | |
| 670 the calendar. Dates can be translated from the (usual) Gregorian | |
| 671 calendar to the day of the year/days remaining in year, to the ISO | |
| 672 commercial calendar, to the Julian (old style) calendar, to the Hebrew | |
| 673 calendar, to the Islamic calendar, to the French Revolutionary calendar, | |
| 674 to the Mayan calendar, and to the astronomical (Julian) day number. | |
| 675 When floating point is available, times of sunrise/sunset can be displayed, | |
| 676 as can the phases of the moon. Appointment notification for diary entries | |
| 677 is available. | |
| 678 *** calendar/cal-dst.el | |
| 679 Commentary: | |
| 680 | |
| 681 This collection of functions implements the features of calendar.el and | |
| 682 holiday.el that deal with daylight savings time. | |
| 683 *** calendar/cal-french.el | |
| 684 Commentary: | |
| 685 | |
| 686 This collection of functions implements the features of calendar.el and | |
| 687 diary.el that deal with the French Revolutionary calendar. | |
| 688 *** calendar/cal-mayan.el | |
| 689 Commentary: | |
| 690 | |
| 691 This collection of functions implements the features of calendar.el and | |
| 692 diary.el that deal with the Mayan calendar. It was written jointly by | |
| 693 *** calendar/cal-x.el | |
| 694 Commentary: | |
| 695 | |
| 696 This collection of functions implements dedicated frames in x-windows for | |
| 697 calendar.el. | |
| 698 *** calendar/cal-xemacs.el | |
| 699 Commentary: | |
| 700 | |
| 701 This collection of functions implements menu bar and popup menu support for | |
| 702 calendar.el. | |
| 703 *** calendar/diary-ins.el | |
| 704 Commentary: | |
| 705 | |
| 706 This collection of functions implements the diary insertion features as | |
| 707 described in calendar.el. | |
| 708 *** calendar/solar.el | |
| 709 Commentary: | |
| 710 | |
| 711 This collection of functions implements the features of calendar.el, | |
| 712 diary.el, and holiday.el that deal with times of day, sunrise/sunset, and | |
| 713 eqinoxes/solstices. | |
| 714 | |
| 715 ** cl - Common Lisp compatibility with Emacs Lisp | |
| 716 *** cl/cl-compat.el | |
| 717 Commentary: | |
| 718 | |
| 719 These are extensions to Emacs Lisp that provide a degree of | |
| 720 Common Lisp compatibility, beyond what is already built-in | |
| 721 in Emacs Lisp. | |
| 722 | |
| 723 ** comint - For running shells, telnet, rsh, gdb, dbx under Emacs | |
| 724 *** comint/comint-xemacs.el | |
| 725 Commentary: | |
| 726 | |
| 727 Declare customizable faces for comint outside the main code so it can | |
| 728 be dumped with XEmacs. | |
| 729 *** comint/comint.el | |
| 730 Commentary: | |
| 731 | |
| 732 This file defines a general command-interpreter-in-a-buffer package | |
| 733 (comint mode). The idea is that you can build specific process-in-a-buffer | |
| 734 modes on top of comint mode -- e.g., lisp, shell, scheme, T, soar, .... | |
| 735 This way, all these specific packages share a common base functionality, | |
| 736 and a common set of bindings, which makes them easier to use (and | |
| 737 saves code, implementation time, etc., etc.). | |
| 738 | |
| 739 Several packages are already defined using comint mode: | |
| 740 - shell.el defines a shell-in-a-buffer mode. | |
| 741 - cmulisp.el defines a simple lisp-in-a-buffer mode. | |
| 742 | |
| 743 - The file cmuscheme.el defines a scheme-in-a-buffer mode. | |
| 744 - The file tea.el tunes scheme and inferior-scheme modes for T. | |
| 745 - The file soar.el tunes lisp and inferior-lisp modes for Soar. | |
| 746 - cmutex.el defines tex and latex modes that invoke tex, latex, bibtex, | |
| 747 previewers, and printers from within emacs. | |
| 748 - background.el allows csh-like job control inside emacs. | |
| 749 *** comint/gdb.el | |
| 750 Commentary: | |
| 751 | |
| 752 A facility is provided for the simultaneous display of the source code | |
| 753 in one window, while using gdb to step through a function in the | |
| 754 other. A small arrow in the source window, indicates the current | |
| 755 line. | |
| 756 *** comint/gud.el | |
| 757 Commentary: | |
| 758 *** comint/history.el | |
| 759 Commentary: | |
| 760 | |
| 761 suggested generic history stuff -- tale | |
| 762 | |
| 763 This is intended to provided easy access to a list of elements | |
| 764 being kept as a history ring. | |
| 765 *** comint/inf-lisp.el | |
| 766 Commentary: | |
| 767 | |
| 768 This file defines a a lisp-in-a-buffer package (inferior-lisp | |
| 769 mode) built on top of comint mode. This version is more | |
| 770 featureful, robust, and uniform than the Emacs 18 version. The | |
| 771 key bindings are also more compatible with the bindings of Hemlock | |
| 772 and Zwei (the Lisp Machine emacs). | |
| 773 *** comint/kermit.el | |
| 774 Commentary: | |
| 775 | |
| 776 I'm not sure, but I think somebody asked about running kermit under shell | |
| 777 mode a while ago. Anyway, here is some code that I find useful. The result | |
| 778 is that I can log onto machines with primitive operating systems (VMS and | |
| 779 ATT system V :-), and still have the features of shell-mode available for | |
| 780 command history, etc. It's also handy to be able to run a file transfer in | |
| 781 an emacs window. The transfer is in the "background", but you can also | |
| 782 monitor or stop it easily. | |
| 783 *** comint/rlogin.el | |
| 784 Commentary: | |
| 785 | |
| 786 Support for remote logins using `rlogin'. | |
| 787 This program is layered on top of shell.el; the code here only accounts | |
| 788 for the variations needed to handle a remote process, e.g. directory | |
| 789 tracking and the sending of some special characters. | |
| 790 *** comint/shell.el | |
| 791 Commentary: | |
| 792 | |
| 793 This file defines a a shell-in-a-buffer package (shell mode) built | |
| 794 on top of comint mode. This is actually cmushell with things | |
| 795 renamed to replace its counterpart in Emacs 18. cmushell is more | |
| 796 featureful, robust, and uniform than the Emacs 18 version. | |
| 797 *** comint/telnet.el | |
| 798 Commentary: | |
| 799 | |
| 800 This mode is intended to be used for telnet or rsh to a remode host; | |
| 801 `telnet' and `rsh' are the two entry points. Multiple telnet or rsh | |
| 802 sessions are supported. | |
| 803 | |
| 804 ** custom - Allow's user to customize Emacs | |
| 805 *** custom/custom.el | |
| 806 Commentary: | |
| 807 | |
| 808 This file only contain the code needed to declare and initialize | |
| 809 user options. The code to customize options is autoloaded from | |
| 810 `cus-edit.el'. | |
| 811 | |
| 812 The code implementing face declarations is in `cus-face.el' | |
| 813 | |
| 814 ** edebug - Emacs Lisp debugger | |
| 815 *** edebug/cl-read.el | |
| 816 Commentary: | |
| 817 | |
| 818 Please send bugs and comments to the author. | |
| 819 | |
| 820 This package replaces the standard Emacs Lisp reader (implemented | |
| 821 as a set of built-in Lisp function in C) by a flexible and | |
| 822 customizable Common Lisp like one (implemented entirely in Emacs | |
| 823 Lisp). During reading of Emacs Lisp source files, it is about 40% | |
| 824 slower than the built-in reader, but there is no difference in | |
| 442 | 825 loading byte compiled files - they don't contain any syntactic sugar |
| 428 | 826 and are loaded with the built in subroutine `load'. |
| 827 | |
| 828 ** ediff - Compare and merge files with graphical difference display | |
| 829 *** ediff/ediff.el | |
| 830 Commentary: | |
| 831 | |
| 832 Never read that diff output again! | |
| 833 Apply patch interactively! | |
| 834 Merge with ease! | |
| 835 | |
| 836 This package provides a convenient way of simultaneous browsing through | |
| 837 the differences between a pair (or a triple) of files or buffers. The | |
| 838 files being compared, file-A, file-B, and file-C (if applicable) are | |
| 839 shown in separate windows (side by side, one above the another, or in | |
| 840 separate frames), and the differences are highlighted as you step | |
| 841 through them. You can also copy difference regions from one buffer to | |
| 842 another (and recover old differences if you change your mind). | |
| 843 | |
| 844 Ediff also supports merging operations on files and buffers, including | |
| 845 merging using ancestor versions. Both comparison and merging operations can | |
| 846 be performed on directories, i.e., by pairwise comparison of files in those | |

| 855 *** electric/ehelp.el | |
| 856 Commentary: | |
| 857 | |
| 858 This package provides a pre-packaged `Electric Help Mode' for | |
| 859 browsing on-line help screens. There is one entry point, | |
| 860 `with-electric-help'; all you have to give it is a no-argument | |
| 861 function that generates the actual text of the help into the current | |
| 862 buffer. | |
| 863 | |
| 864 ** emulators - Various emulations: mocklisp, teco, TPU/EDT, WordStar | |
| 865 *** emulators/mlconvert.el | |
| 866 Commentary: | |
| 867 | |
| 868 This package converts Mocklisp code written under a Gosling or UniPress | |
| 869 Emacs for use with GNU Emacs. The translated code will require runtime | |
| 870 support from the mlsupport.el equivalent. | |
| 871 *** emulators/mlsupport.el | |
| 872 Commentary: | |
| 873 | |
| 874 This package provides equivalents of certain primitives from Gosling | |
| 875 Emacs (including the commercial UniPress versions). These have an | |
| 876 ml- prefix to distinguish them from native GNU Emacs functions with | |
| 877 similar names. The package mlconvert.el translates Mocklisp code | |
| 878 to use these names. | |
| 879 *** emulators/teco.el | |
| 880 Commentary: | |
| 881 | |
| 882 This code has been tested some, but no doubt contains a zillion bugs. | |
| 883 You have been warned. | |

| 888 Commentary: | |
| 889 | |
| 890 %% TPU-edt -- Emacs emulating TPU emulating EDT | |
| 891 | |
| 892 %% Introduction | |
| 893 | |
| 894 TPU-edt emulates the popular DEC VMS editor EDT (actually, it emulates | |
| 895 DEC TPU's EDT emulation, hence the name TPU-edt). | |
| 896 *** emulators/tpu-extras.el | |
| 897 Commentary: | |
| 898 | |
| 899 Use the functions defined here to customize TPU-edt to your tastes by | |
| 900 setting scroll margins and/or turning on free cursor mode. Here's an | |
| 901 example for your .emacs file. | |
| 902 *** emulators/ws-mode.el | |
| 903 Commentary: | |
| 904 | |
| 905 This emulates WordStar, with a major mode. | |
| 906 | |
| 907 ** energize - Interface to now-defunct Lucid's C/C++ integrated | |

| 912 | |
| 913 ** eterm - Full terminal emulation under Emacs | |
| 914 *** eterm/term.el | |
| 915 Commentary: | |
| 916 | |
| 917 This file defines a general command-interpreter-in-a-buffer package | |
| 918 (term mode). The idea is that you can build specific process-in-a-buffer | |
| 919 modes on top of term mode -- e.g., lisp, shell, scheme, T, soar, .... | |
| 920 This way, all these specific packages share a common base functionality, | |
| 921 and a common set of bindings, which makes them easier to use (and | |
| 922 saves code, implementation time, etc., etc.). | |
| 923 *** eterm/tgud.el | |
| 924 Commentary: | |
| 925 | |
| 926 The ancestral gdb.el was by W. Schelter <wfs@rascal.ics.utexas.edu> | |
| 927 It was later rewritten by rms. Some ideas were due to Masanobu. | |
| 928 Grand Unification (sdb/dbx support) by Eric S. Raymond <esr@thyrsus.com> | |
| 929 The overloading code was then rewritten by Barry Warsaw <bwarsaw@cen.com>, | |
| 930 who also hacked the mode to use comint.el. Shane Hartman <shane@spr.com> | |
| 931 added support for xdb (HPUX debugger). Rick Sladkey <jrs@world.std.com> | |
| 932 wrote the GDB command completion code. Dave Love <d.love@dl.ac.uk> | |
| 933 added the IRIX kluge and re-implemented the Mips-ish variant. | |
| 934 Then hacked by Per Bothner <bothner@cygnus.com> to use term.el. | |
| 935 *** eterm/tshell.el | |
| 936 Commentary: | |
| 937 | |
| 938 This file defines a a shell-in-a-buffer package (shell mode) built | |
| 939 on top of term mode. This is actually cmushell with things | |
| 940 renamed to replace its counterpart in Emacs 18. cmushell is more | |
| 941 featureful, robust, and uniform than the Emacs 18 version. | |
| 942 | |
| 943 ** games - blackbox, mines, decipher, doctor, ... | |
| 944 *** games/blackbox.el | |
| 945 Commentary: | |
| 946 | |
| 947 The object of the game is to find four hidden balls by shooting rays | |
| 948 into the black box. There are four possibilities: 1) the ray will | |
| 949 pass thru the box undisturbed, 2) it will hit a ball and be absorbed, | |
| 950 3) it will be deflected and exit the box, or 4) be deflected immediately, | |
| 951 not even being allowed entry into the box. | |
| 952 *** games/conx.el | |
| 953 Commentary: | |
| 954 | |
| 955 conx.el: Yet Another Dissociator. | |
| 956 | |
| 957 Select a buffer with a lot of text in it. Say M-x conx-buffer | |
| 958 or M-x conx-region. Repeat on as many other bodies of text as | |
| 959 you like. | |
| 960 | |
| 961 M-x conx will use the word-frequency tree the above generated | |
| 962 to produce random sentences in a popped-up buffer. It will pause | |
| 963 at the end of each paragraph for two seconds; type ^G to stop it. | |
| 964 *** games/cookie1.el | |
| 965 Commentary: | |
| 966 | |
| 967 Support for random cookie fetches from phrase files, used for such | |
| 968 critical applications as emulating Zippy the Pinhead and confounding | |
| 969 the NSA Trunk Trawler. | |
| 970 *** games/decipher.el | |
| 971 Commentary: | |
| 972 | |
| 973 This package is designed to help you crack simple substitution | |
| 974 ciphers where one letter stands for another. It works for ciphers | |
| 975 with or without word divisions. (You must set the variable | |
| 976 decipher-ignore-spaces for ciphers without word divisions.) | |
| 977 *** games/dissociate.el | |
| 978 Commentary: | |
| 979 | |
| 980 The single entry point, `dissociated-press', applies a travesty | |
| 981 generator to the current buffer. The results can be quite amusing. | |
| 982 *** games/doctor.el | |
| 983 Commentary: | |
| 984 | |
| 985 The single entry point `doctor', simulates a Rogerian analyst using | |
| 986 phrase-production techniques similar to the classic ELIZA demonstration | |
| 987 of pseudo-AI. | |
| 988 *** games/flame.el | |
| 989 Commentary: | |
| 990 | |
| 991 "Flame" program. This has a chequered past. | |
| 992 *** games/gomoku.el | |
| 993 Gomoku is a game played between two players on a rectangular board. Each | |
| 994 player, in turn, marks a free square of its choice. The winner is the first | |
| 995 one to mark five contiguous squares in any direction (horizontally, | |
| 996 vertically or diagonally). | |
| 997 | |
| 998 *** games/hanoi.el | |
| 999 Commentary: | |
| 1000 | |
| 1001 Solves the Towers of Hanoi puzzle while-U-wait. | |
| 1002 | |
| 1003 The puzzle: Start with N rings, decreasing in sizes from bottom to | |
| 1004 top, stacked around a post. There are two other posts. Your mission, | |
| 1005 should you choose to accept it, is to shift the pile, stacked in its | |
| 1006 original order, to another post. | |
| 1007 *** games/life.el | |
| 1008 Commentary: | |
| 1009 | |
| 1010 A demonstrator for John Horton Conway's "Life" cellular automaton | |
| 1011 in Emacs Lisp. Picks a random one of a set of interesting Life | |
| 1012 patterns and evolves it according to the familiar rules. | |
| 1013 *** games/mine.el | |
| 1014 Commentary: | |
| 1015 | |
| 1016 The object of this classical game is to locate the hidden mines. | |
| 1017 To do this, you hit the squares on the game board that do not | |
| 1018 contain mines, and you mark the squares that do contain mines. | |
| 1019 *** games/mpuz.el | |
| 1020 Commentary: | |
| 1021 | |
| 1022 When this package is loaded, `M-x mpuz' generates a random multiplication | |
| 1023 puzzle. This is a multiplication example in which each digit has been | |
| 1024 consistently replaced with some letter. Your job is to reconstruct | |
| 1025 the original digits. Type `?' while the mode is active for detailed help. | |
| 1026 *** games/spook.el | |
| 1027 Commentary: | |
| 1028 | |
| 1029 Just before sending mail, do M-x spook. | |
| 1030 A number of phrases will be inserted into your buffer, to help | |
| 1031 give your message that extra bit of attractiveness for automated | |
| 1032 keyword scanners. | |
| 1033 *** games/studly.el | |
| 1034 Commentary: | |
| 1035 | |
| 1036 Functions to studlycapsify a region, word, or buffer. Possibly the | |
| 1037 esoteric significance of studlycapsification escapes you; that is, | |
| 1038 you suffer from autostudlycapsifibogotification. Too bad. | |
| 1039 *** games/yow.el | |
| 1040 Commentary: | |
| 1041 | |
| 1042 Important pinheadery for GNU Emacs. | |
| 1043 | |
| 1044 See cookie1.el for implementation. Note --- the `n' argument of yow | |
| 1045 from the 18.xx implementation is no longer; we only support *random* | |
| 1046 random access now. | |

| 1048 ** gnus - The ultimate News and Mail reader | |
| 1049 See online manual | |
| 1050 *** gnus/gnus-audio.el | |
| 1051 Commentary: | |
| 1052 This file provides access to sound effects in Gnus. | |
| 1053 Prerelease: This file is partially stripped to support earcons.el | |
| 1054 You can safely ignore most of it until Red Gnus. **Evil Laugh** | |
| 1055 *** gnus/gnus-gl.el | |
| 1056 Commentary: | |
| 1057 *** gnus/gnus-undo.el | |
| 1058 Commentary: | |
| 1059 | |
| 1060 This package allows arbitrary undoing in Gnus buffers. As all the | |
| 1061 Gnus buffers aren't very text-oriented (what is in the buffers is | |
| 1062 just some random representation of the actual data), normal Emacs | |
| 1063 undoing doesn't work at all for Gnus. | |
| 1064 *** gnus/mailheader.el | |
| 1065 Commentary: | |
| 1066 | |
| 1067 This package provides an abstraction to RFC822-style messages, used in | |
| 1068 mail news, and some other systems. The simple syntactic rules for such | |
| 1069 headers, such as quoting and line folding, are routinely reimplemented | |
| 1070 in many individual packages. This package removes the need for this | |
| 1071 redundancy by representing message headers as association lists, | |
| 1072 offering functions to extract the set of headers from a message, to | |
| 1073 parse individual headers, to merge sets of headers, and to format a set | |
| 1074 of headers. | |
| 1075 *** gnus/message.el | |
| 1076 Commentary: | |
| 1077 | |
| 1078 This mode provides mail-sending facilities from within Emacs. It | |
| 1079 consists mainly of large chunks of code from the sendmail.el, | |
| 1080 gnus-msg.el and rnewspost.el files. | |
| 1081 *** gnus/nnheader.el | |
| 1082 Commentary: | |
| 1083 | |
| 1084 These macros may look very much like the ones in GNUS 4.1. They | |
| 1085 are, in a way, but you should note that the indices they use have | |
| 1086 been changed from the internal GNUS format to the NOV format. The | |
| 1087 makes it possible to read headers from XOVER much faster. | |

| 1100 | |
| 1101 Function `iso-accents-mode' activates a minor mode in which | |
| 1102 typewriter "dead keys" are emulated. The purpose of this emulation | |
| 1103 is to provide a simple means for inserting accented characters | |
| 1104 according to the ISO-8859-1 character set. | |

| 1174 Commentary: | |
| 1175 | |
| 1176 Boring old c-mode.el (BOCM) is confusion and brain melt. cc-mode.el | |
| 1177 is clarity of thought and purity of chi. If you are still unwilling | |
| 1178 to accept enlightenment, this might help, or it may prolong your | |
| 1179 agony. | |
| 1180 *** modes/cc-guess.el | |
| 1181 Commentary: | |
| 1182 | |
| 1183 This file contains routines that help guess the cc-mode style in a | |
| 1184 particular region of C, C++, or Objective-C code. It is provided | |
| 1185 for example and experimentation only. It is not supported in | |
| 1186 anyway. Some folks have asked for a style guesser and the best way | |
| 1187 to show my thoughts on the subject is with this sample code. Feel | |
| 1188 free to improve upon it in anyway you'd like. Please send me the | |
| 1189 results. Note that style guessing is lossy! | |
| 1190 *** modes/cc-lobotomy.el | |
| 1191 Commentary: | |
| 1192 | |
| 1193 Every effort has been made to improve the performance of | |
| 1194 cc-mode. However, due to the nature of the C, C++, and Objective-C | |
| 1195 language definitions, a trade-off is often required between | |
| 1196 accuracy of construct recognition and speed. I believe it is always | |
| 1197 best to be correct, and that the mode is currently fast enough for | |
| 1198 most normal usage. Others disagree. I have no intention of | |
| 1199 including these hacks in the main distribution. When cc-mode | |
| 1200 version 5 comes out, it will include a rewritten indentation engine | |
| 1201 so that performance will be greatly improved automatically. This | |
| 1202 was not included in this release of version 4 so that Emacs 18 | |
| 1203 could still be supported. Note that this implies that cc-mode | |
| 1204 version 5 will *not* work on Emacs 18! | |
| 1205 *** modes/cc-mode.el | |
| 1206 Commentary: | |
| 1207 | |
| 1208 This package provides modes in GNU Emacs for editing C, C++, | |
| 1209 Objective-C, and Java code. It is intended to be a replacement for | |
| 1210 c-mode.el (a.k.a. BOCM -- Boring Old C-Mode), c++-mode.el, | |
| 1211 cplus-md.el, and cplus-md1.el, all of which are in some way | |
| 1212 ancestors of this file. A number of important improvements have | |
| 1213 been made, briefly: complete K&R C, ANSI C, `ARM' C++, Objective-C, | |
| 1214 and Java support with consistent indentation across all modes, more | |
| 1215 intuitive indentation controlling variables, compatibility across | |
| 1216 all known Emacsen, nice new features, and tons of bug fixes. This | |
| 1217 package is called "CC Mode" to distinguish it from its ancestors, | |
| 1218 but there is no cc-mode command. Usage and programming details are | |
| 1219 contained in an accompanying texinfo manual. | |
| 1220 *** modes/cl-indent.el | |
| 1221 Commentary: | |
| 1222 | |
| 1223 This package supplies a single entry point, common-lisp-indent-function, | |
| 1224 which performs indentation in the preferred style for Common Lisp code. | |

| 1229 Commentary: | |
| 1230 | |
| 1231 executable.el is used by certain major modes to insert a suitable | |
| 1232 #! line at the beginning of the file, if the file does not already | |
| 1233 have one. | |
| 1234 | |
| 1235 *** modes/f90.el | |
| 1236 Commentary: | |
| 1237 | |
| 1238 Smart mode for editing F90 programs in FREE FORMAT. | |
| 1239 Knows about continuation lines, named structured statements, and other | |
| 1240 new features in F90 including HPF (High Performance Fortran) structures. | |
| 1241 The basic feature is to provide an accurate indentation of F90 programs. | |
| 1242 In addition, there are many more features like automatic matching of all | |
| 1243 end statements, an auto-fill function to break long lines, a join-lines | |
| 1244 function which joins continued lines etc etc. | |
| 1245 To facilitate typing, a fairly complete list of abbreviations is provided. | |
| 1246 For example, `i is short-hand for integer (if abbrev-mode is on). | |
| 1247 | |
| 1248 *** modes/follow.el | |
| 1249 Commentary: | |
| 1250 | |
| 1251 `Follow mode' is a minor mode for Emacs 19 and XEmacs which | |
| 1252 combines windows into one tall virtual window. | |
| 1253 | |
| 1254 The feeling of a "virtual window" has been accomplished by the use | |
| 1255 of two major techniques: | |
| 1256 | |
| 1257 * The windows always displays adjacent sections of the buffer. | |
| 1258 This means that whenever one window is moved, all the | |
| 1259 others will follow. (Hence the name Follow Mode.) | |
| 1260 | |
| 1261 * Should the point (cursor) end up outside a window, another | |
| 1262 window displaying that point is selected, if possible. This | |
| 1263 makes it possible to walk between windows using normal cursor | |
| 1264 movement commands. | |
| 1265 *** modes/fortran.el | |
| 1266 Commentary: | |
| 1267 | |
| 1268 Fortran mode has been upgraded and is now maintained by Stephen A. Wood | |
| 1269 (saw@cebaf.gov). It now will use either fixed format continuation line | |
| 1270 markers (character in 6th column), or tab format continuation line style | |
| 1271 (digit after a TAB character.) A auto-fill mode has been added to | |
| 1272 automatically wrap fortran lines that get too long. | |

| 1279 Commentary: | |
| 1280 | |
| 1281 Hide-ifdef suppresses the display of code that the preprocessor wouldn't | |
| 1282 pass through. The support of constant expressions in #if lines is | |
| 1283 limited to identifiers, parens, and the operators: &&, ||, !, and | |
| 1284 "defined". Please extend this. | |
| 1285 *** modes/hideshow.el | |
| 1286 Commentary: | |
| 1287 | |
| 1288 This file provides `hs-minor-mode'. When active, six commands: | |
| 1289 hs-{hide,show}-{all,block}, hs-show-region and hs-minor-mode | |
| 1290 are available. They implement block hiding and showing. Blocks are | |
| 1291 defined in mode-specific way. In c-mode or c++-mode, they are simply | |
| 1292 curly braces, while in lisp-ish modes they are parens. Multi-line | |
| 1293 comments (c-mode) can also be hidden. The command M-x hs-minor-mode | |
| 1294 toggles the minor mode or sets it (similar to outline minor mode). | |
| 1295 See documentation for each command for more info. | |

| 1393 Commentary: | |
| 1394 | |
| 1395 This package allows the entire contents (or as much as possible) of the | |
| 1396 minibuffer to be visible at once when typing. As the end of a line is | |
| 1397 reached, the minibuffer will resize itself. When the user is done | |
| 1398 typing, the minibuffer will return to its original size. | |
| 1399 *** modes/scheme.el | |
| 1400 Commentary: | |
| 1401 | |
| 1402 Adapted from Lisp mode by Bill Rozas, jinx@prep. | |
| 1403 Initially a query replace of Lisp mode, except for the indentation | |
| 1404 of special forms. Probably the code should be merged at some point | |
| 1405 so that there is sharing between both libraries. | |

| 1450 Commentary: | |
| 1451 | |
| 1452 This package provides the `view' minor mode documented in the Emacs | |
| 1453 user's manual. | |
| 1454 | |
| 1455 XEmacs: We don't autoload this because we use `view-less' instead. | |
| 1456 *** modes/vrml-mode.el | |
| 1457 Commentary: | |
| 1458 | |
| 1459 Mostly bastardized from tcl.el. | |
| 1460 *** modes/whitespace-mode.el | |
| 1461 Commentary: | |
| 1462 | |
| 1463 This is a minor mode, which highlights whitespaces (blanks and | |
| 1464 tabs) with different faces, so that it is easier to | |
| 1465 distinguish between them. | |
| 1466 Toggle the mode with: M-x whitespace-mode | |
| 1467 or with: M-x whitespace-incremental-mode | |
| 1468 The second one should be used in big files. | |

| 1490 Commentary: | |
| 1491 | |
| 1492 The ideas for this package were derived from the C code in | |
| 1493 src/keymap.c and elsewhere. The functions in this file should | |
| 1494 always be byte-compiled for speed. Someone should rewrite this in | |
| 1495 C (as part of src/keymap.c) for speed. | |
| 1496 *** packages/array.el | |
| 1497 Commentary: | |
| 1498 | |

| 1506 The following defines an association list for text to be | |
| 1507 automatically inserted when a new file is created, and a function | |
| 1508 which automatically inserts these files; the idea is to insert | |
| 1509 default text much as the mode is automatically set using | |
| 1510 auto-mode-alist. | |

| 1516 the way, or all the way to the corner of the frame. | |
| 1517 To use, load or evaluate this file and type M-x mouse-avoidance-mode . | |
| 1518 To set up permanently, put this file on your .emacs: | |

| 1528 Edit, delete, or change attributes of all currently active Emacs | |
| 1529 buffers from a list summarizing their state. A good way to browse | |
| 1530 any special or scratch buffers you have loaded, since you can't find | |
| 1531 them by filename. The single entry point is `Buffer-menu-mode', | |
| 1532 normally bound to C-x C-b. | |
| 1533 *** packages/chistory.el | |
| 1534 Commentary: | |
| 1535 | |
| 1536 This really has nothing to do with list-command-history per se, but | |
| 1537 its a nice alternative to C-x ESC ESC (repeat-complex-command) and | |
| 1538 functions as a lister if given no pattern. It's not important | |
| 1539 enough to warrant a file of its own. | |

| 1591 *** packages/hexl.el | |
| 1592 Commentary: | |
| 1593 | |
| 1594 This package implements a major mode for editing binary files. It uses | |
| 1595 a program called hexl, supplied with the GNU Emacs distribution, that | |
| 1596 can filter a binary into an editable format or from the format back into | |
| 1597 binary. For full instructions, invoke `hexl-mode' on an empty buffer and | |
| 1598 do `M-x describe-mode'. | |
| 1599 *** packages/hyper-apropos.el | |
| 1600 Commentary: | |
| 1601 | |
| 1602 Rather than run apropos and print all the documentation at once, | |
| 1603 I find it easier to view a "table of contents" first, then | |
| 1604 get the details for symbols as you need them. | |
| 1605 *** packages/icomplete.el | |
| 1606 Commentary: | |
| 1607 | |
| 1608 Loading this package implements a more fine-grained minibuffer | |

| 1619 | |
| 1620 This package implements low-level support for reading, writing, | |
| 1621 and loading compressed files. It hooks into the low-level file | |
| 1622 I/O functions (including write-region and insert-file-contents) so | |
| 1623 that they automatically compress or uncompress a file if the file | |
| 1624 appears to need it (based on the extension of the file name). | |
| 1625 Packages like Rmail, VM, GNUS, and Info should be able to work | |
| 1626 with compressed files without modification. | |
| 1627 *** packages/lazy-lock.el | |
| 1628 Commentary: | |
| 1629 | |
| 1630 Purpose: | |
| 1631 | |

| 1657 Commentary: | |
| 1658 | |

| 1660 the environment variables. For that reason, matamail.el have to | |
| 1661 hack the environment variables. In addition, there is no way to | |
| 1662 display all header fields without extra informative body messages | |
| 1663 which are suppressed by "-q" option. | |
| 1664 | |
| 1665 The idea of using metamail to process MIME messages is from | |

| 1690 This package provides printing of Emacs buffers on PostScript | |
| 1691 printers; the buffer's bold and italic text attributes are | |
| 1692 preserved in the printer output. Ps-print is intended for use with | |
| 1693 Emacs 19 or Lucid Emacs, together with a fontifying package such as | |
| 1694 font-lock or hilit. | |
| 1695 *** packages/rcompile.el | |
| 1696 Commentary: | |
| 1697 | |
| 1698 This package is for running a remote compilation and using emacs to parse | |
| 1699 the error messages. It works by rsh'ing the compilation to a remote host | |
| 1700 and parsing the output. If the file visited at the time remote-compile was | |
| 1701 called was loaded remotely (ange-ftp), the host and user name are obtained | |
| 1702 by the calling ange-ftp-ftp-name on the current directory. In this case the | |
| 1703 next-error command will also ange-ftp the files over. This is achieved | |
| 1704 automatically because the compilation-parse-errors function uses | |
| 1705 default-directory to build it's file names. If however the file visited was | |
| 1706 loaded locally, remote-compile prompts for a host and user and assumes the | |
| 1707 files mounted locally (otherwise, how was the visited file loaded). | |

| 1720 | |
| 1721 The purpose of this library is to handle command line arguments | |
| 1722 when you resume an existing Emacs job. | |
| 1723 | |
| 1724 You can't get the benefit of this library by using the `emacs' command, | |
| 1725 since that always starts a new Emacs job. Instead you must use a | |
| 1726 command called `edit' which knows how to resume an existing Emacs job | |
| 1727 if you have one, or start a new Emacs job if you don't have one. | |
| 1728 | |
| 1729 To define the `edit' command, run the script etc/emacs.csh (if you use CSH), | |

| 1768 If you put a time stamp template anywhere in the first 8 lines of a file, | |
| 1769 it can be updated every time you save the file. See the top of | |
| 1770 time-stamp.el for a sample. The template looks like one of the following: | |
| 1771 Time-stamp: <> | |
| 1772 Time-stamp: " " | |
| 1773 The time stamp is written between the brackets or quotes, resulting in | |

| 1782 | |
| 1783 This package can be used to arrange for automatic uncompress of | |

| 1788 Commentary: | |
| 1789 | |
| 1790 This package deals with the primitive form of underlining | |
| 1791 consisting of prefixing each character with "_\^h". The entry | |
| 1792 point `underline-region' performs such underlining on a region. | |

| 1816 | |
| 1817 Introduction | |
| 1818 ============ | |
| 1819 | |
| 1820 Cookie is a package that implements a connection between an | |
| 1821 dll (a doubly linked list) and the contents of a buffer. | |
| 1822 Possible uses are dired (have all files in a list, and show them), | |
| 1823 buffer-list, kom-prioritize (in the LysKOM elisp client) and | |
| 1824 others. pcl-cvs.el uses cookie.el. | |
| 1825 *** pcl-cvs/dll-debug.el | |
| 1826 Commentary: | |
| 1827 | |
| 1828 This is a plug-in replacement for dll.el. It is dreadfully | |
| 1829 slow, but it facilitates debugging. Don't trust the comments in | |
| 1830 this file too much. | |
| 1831 (provide 'dll) | |
| 1832 | |
| 1833 *** pcl-cvs/dll.el | |
| 1834 Commentary: | |
| 1835 | |
| 1836 A doubly linked list consists of one cons cell which holds the tag | |
| 1837 'DL-LIST in the car cell and a pointer to a dummy node in the cdr | |
| 1838 cell. The doubly linked list is implemented as a circular list | |
| 1839 with the dummy node first and last. The dummy node is recognized | |
| 1840 by comparing it to the node which the cdr of the cons cell points | |
| 1841 to. | |
| 1842 | |
| 1843 *** pcl-cvs/elib-node.el | |
| 1844 Commentary: | |
| 1845 | |
| 1846 A node is implemented as an array with three elements, using | |
| 1847 (elt node 0) as the left pointer | |
| 1848 (elt node 1) as the right pointer | |
| 1849 (elt node 2) as the data | |

| 1984 points, `list-options' and `edit' options'. The latter enters a major | |

| 2005 *** prim/register.el | |
| 2006 Commentary: | |
| 2007 | |
| 2008 This package of functions emulates and somewhat extends the venerable | |
| 2009 TECO's `register' feature, which permits you to save various useful | |
| 2010 pieces of buffer state to named variables. The entry points are | |
| 2011 documented in the XEmacs Reference Manual. | |
| 2012 *** prim/replace.el | |
| 2013 Commentary: | |
| 2014 | |
| 2015 This package supplies the string and regular-expression replace functions | |
| 2016 documented in the XEmacs Reference Manual. | |
| 2017 | |
| 2018 All the gettext calls are for XEmacs I18N3 message catalog support. | |
| 2019 *** prim/reposition.el | |
| 2020 Commentary: | |
| 2021 | |
| 2022 Reposition-window makes an entire function definition or comment visible, | |
| 2023 or, if it is already visible, places it at the top of the window; | |
| 2024 additional invocations toggle the visibility of comments preceding the | |
| 2025 code. For the gory details, see the documentation for reposition-window; | |
| 2026 rather than reading that, you may just want to play with it. | |
| 2027 | |
| 2028 This tries pretty hard to do the recentering correctly; the precise | |
| 2029 action depends on what the buffer looks like. If you find a situation | |
| 2030 where it doesn't behave well, let me know. This function is modeled | |
| 2031 after one of the same name in ZMACS, but the code is all-new and the | |
| 2032 behavior in some situations differs. | |

| 2054 *** prim/symbols.el | |
| 2055 Commentary: | |
| 2056 | |
| 2057 The idea behind magic variables is that you can specify arbitrary | |
| 2058 behavior to happen when setting or retrieving a variable's value. The | |
| 2059 purpose of this is to make it possible to cleanly provide support for | |
| 2060 obsolete variables (e.g. unread-command-event, which is obsolete for | |
| 2061 unread-command-events) and variable compatibility | |
| 2062 (e.g. suggest-key-bindings, the FSF equivalent of | |

| 2107 Commentary: | |
| 2108 | |
| 2109 The function `style-format' formats the SGML-file in the current | |
| 2110 buffer according to the style defined in the file `psgml-style.fs' | |
| 2111 (or the file given by the variable `fs-style'). | |
| 2112 | |
| 2113 To try it load this file and open the test file example.sgml. Then | |
| 2114 run the emacs command `M-x style-format'. | |
| 2115 | |
| 2116 The style file should contain a single Lisp list. The elements of | |
| 2117 this list, are them self lists, describe the style for an element type. | |
| 2118 The sublists begin with the generic identifier for the element types and | |
| 2119 the rest of the list are characteristic/value pairs. | |
| 2120 | |
| 2121 E.g. ("p" block t left 4 top 2) | |
| 2122 | |
| 2123 Defines the style for p-elements to be blocks with left margin 4 and | |
| 2124 at least to blank lines before the block. | |

| 2171 a HTML editing mode written by Nelson Minar <nelson@santafe.edu>, | |
| 2172 and his html-helper-mode.el is probably the best example of how to | |
| 2173 use this program. | |

| 2281 that win32 windows are to be used. Command line switches are parsed and those | |
| 2282 pertaining to win32 are processed and removed from the command line. The | |
| 2283 win32 display is opened and hooks are set for popping up the initial window. | |
| 2284 | |

| 2291 rocks. The left-arrow key emits a backspace (!) and the down-arrow a line | |
| 2292 feed (!!). Thus, you have to unbind some commonly-used Emacs keys to | |
| 2293 enable the arrows. | |

| 2400 Commentary: | |
| 2401 | |
| 2402 This package implements a full-fledged Lisp-style advice mechanism | |
| 2403 for Emacs Lisp. Advice is a clean and efficient way to modify the | |
| 2404 behavior of Emacs Lisp functions without having to keep personal | |
| 2405 modified copies of such functions around. A great number of such | |
| 2406 modifications can be achieved by treating the original function as a | |
| 2407 black box and specifying a different execution environment for it | |
| 2408 with a piece of advice. Think of a piece of advice as a kind of fancy | |
| 2409 hook that you can attach to any function/macro/subr. | |

| 2448 which (on systems that need it) is used during installation | |
| 2449 to give appropriate permissions to movemail. | |

| 2457 This package provides functions which read a URL (Uniform Resource | |
| 2458 Locator) from the minibuffer, defaulting to the URL around point, | |
| 2459 and ask a World-Wide Web browser to load it. It can also load the | |
| 2460 URL associated with the current buffer. Different browsers use | |
| 2461 different methods of remote control so there is one function for | |
| 2462 each supported browser. If the chosen browser is not running, it | |
| 2463 is started. Currently there is support for: | |

| 2467 *** utils/derived.el | |
| 2468 Commentary: | |
| 2469 | |
| 2470 GNU Emacs is already, in a sense, object oriented -- each object | |
| 2471 (buffer) belongs to a class (major mode), and that class defines | |
| 2472 the relationship between messages (input events) and methods | |
| 2473 (commands) by means of a keymap. | |
| 2474 | |
| 2475 In the mean time, this package offers most of the advantages of | |
| 2476 full inheritance with the existing major modes. The macro | |
| 2477 `define-derived-mode' allows the user to make a variant of an existing | |
| 2478 major mode, with its own keymap. The new mode will inherit the key | |
| 2479 bindings of its parent, and will, in fact, run its parent first | |
| 2480 every time it is called. For example, the commands | |

| 2484 WARNING. DANGER. This file reportedly crashes 19.14, use it only with a | |

| 2488 *** utils/docref.el | |
| 2489 Commentary: | |
| 2490 | |
| 2491 This package allows you to use a simple form of cross references in | |
| 2492 your Emacs Lisp documentation strings. Cross-references look like | |
| 2493 \\(type@[label@]data), where type defines a method for retrieving | |
| 2494 reference informatin, data is used by a method routine as an argument, | |
| 2495 and label "represents" the reference in text. If label is absent, data | |
| 2496 is used instead. | |

| 2500 | |
| 2501 Usage: | |
| 2502 | |
| 2503 The `C-x C-k' (`edit-kbd-macro') command edits a keyboard macro | |
| 2504 in a special buffer. It prompts you to type a key sequence, | |
| 2505 which should be one of: | |
| 2506 *** utils/eldoc.el | |
| 2507 Commentary: | |
| 2508 | |
| 2509 This program was inspired by the behavior of the "mouse documentation | |
| 2510 window" on many Lisp Machine systems; as you type a function's symbol | |
| 2511 name as part of a sexp, it will print the argument list for that | |
| 2512 function. Behavior is not identical; for example, you need not actually | |
| 2513 type the function name, you need only move point around in a sexp that | |
| 2514 calls it. Also, if point is over a documented variable, it will print | |
| 2515 the one-line documentation for that variable instead, to remind you of | |
| 2516 that variable's meaning. | |
| 2517 *** utils/elp.el | |
| 2518 Commentary: | |
| 2519 | |
| 2520 If you want to profile a bunch of functions, set elp-function-list | |
| 2521 to the list of symbols, then do a M-x elp-instrument-list. This | |
| 2522 hacks those functions so that profiling information is recorded | |
| 2523 whenever they are called. To print out the current results, use | |
| 2524 M-x elp-results. If you want output to go to standard-output | |
| 2525 instead of a separate buffer, setq elp-use-standard-output to | |
| 2526 non-nil. With elp-reset-after-results set to non-nil, profiling | |
| 2527 information will be reset whenever the results are displayed. You | |
| 2528 can also reset all profiling info at any time with M-x | |
| 2529 elp-reset-all. | |
| 2530 *** utils/facemenu.el | |
| 2531 Commentary: | |
| 2532 | |
| 2533 This file defines a menu of faces (bold, italic, etc) which allows you to | |
| 2534 set the face used for a region of the buffer. Some faces also have | |
| 2535 keybindings, which are shown in the menu. Faces with names beginning with | |
| 2536 "fg:" or "bg:", as in "fg:red", are treated specially. | |
| 2537 Such faces are assumed to consist only of a foreground (if "fg:") or | |
| 2538 background (if "bg:") color. They are thus put into the color submenus | |
| 2539 rather than the general Face submenu. These faces can also be | |
| 2540 automatically created by selecting the "Other..." menu items in the | |
| 2541 "Foreground" and "Background" submenus. | |

| 2546 This expects the Emacs sources to live in emacs-source-directory. | |
| 2547 It creates a temporary working directory /tmp/esrc. | |
| 2548 *** utils/finder.el | |
| 2549 Commentary: | |
| 2550 | |
| 2551 This mode uses the Keywords library header to provide code-finding | |
| 2552 services by keyword. | |
| 2553 *** utils/floating-toolbar.el | |
| 2554 Commentary: | |
| 2555 | |
| 2556 The command `floating-toolbar' pops up a small frame | |
| 2557 containing a toolbar. The command should be bound to a | |
| 2558 button-press event. If the mouse press happens over an | |
| 2559 extent that has a non-nil 'floating-toolbar property, the | |
| 2560 value of that property is the toolbar instantiator that will | |
| 2561 be displayed. Otherwise the toolbar displayed is taken from | |
| 2562 the variable `floating-toolbar'. This variable can be made | |
| 2563 buffer local to produce buffer local floating toolbars. | |
| 2564 *** utils/flow-ctrl.el | |
| 2565 Commentary: | |
| 2566 | |
| 2567 Terminals that use XON/XOFF flow control can cause problems with | |
| 2568 GNU Emacs users. This file contains Emacs Lisp code that makes it | |

| 2572 *** utils/foldout.el | |
| 2573 Commentary: | |
| 2574 | |
| 2575 This file provides folding editor extensions for outline-mode and | |
| 2576 outline-minor-mode buffers. What's a "folding editor"? Read on... | |
| 2577 | |
| 2578 Imagine you're in an outline-mode buffer and you've hidden all the text and | |
| 2579 subheadings under your level-1 headings. You now want to look at the stuff | |
| 2580 hidden under one of these headings. Normally you'd do C-c C-e (show-entry) | |
| 2581 to expose the body or C-c C-i to expose the child (level-2) headings. | |
| 2582 | |
| 2583 With foldout, you do C-c C-z (foldout-zoom-subtree). This exposes the body | |
| 2584 and child subheadings and narrows the buffer so that only the level-1 | |
| 2585 heading, the body and the level-2 headings are visible. If you now want to | |
| 2586 look under one of the level-2 headings, position the cursor on it and do C-c | |
| 2587 C-z again. This exposes the level-2 body and its level-3 child subheadings | |
| 2588 and narrows the buffer again. You can keep on zooming in on successive | |
| 2589 subheadings as much as you like. A string in the modeline tells you how | |
| 2590 deep you've gone. | |

| 2596 Visit a file using a form. | |
| 2597 | |
| 2598 Forms mode means visiting a data file which is supposed to consist | |
| 2599 of records each containing a number of fields. The records are | |
| 2600 separated by a newline, the fields are separated by a user-defined | |
| 2601 field separator (default: TAB). | |
| 2602 When shown, a record is transferred to an Emacs buffer and | |
| 2603 presented using a user-defined form. One record is shown at a | |
| 2604 time. | |

| 2620 | |
| 2621 Given an RFC-822 ADDRESS, extract full name and canonical address. | |
| 2622 Returns a list of the form (FULL-NAME CANONICAL-ADDRESS). | |
| 2623 If no name can be extracted, FULL-NAME will be nil. | |
| 2624 ADDRESS may be a string or a buffer. If it is a buffer, the visible | |
| 2625 (narrowed) portion of the buffer will be interpreted as the address. | |
| 2626 (This feature exists so that the clever caller might be able to avoid | |
| 2627 consing a string.) | |

| 2646 It asks a series of y/n questions (a la y-or-n-p), and decides to | |
| 2647 applies an action to each element of a list based on the answer. | |
| 2648 The nice thing is that you also get some other possible answers | |
| 2649 to use, reminiscent of query-replace: ! to answer y to all remaining | |
| 2650 questions; ESC or q to answer n to all remaining questions; . to answer | |
| 2651 y once and then n for the remainder; and you can get help with C-h. | |

| 2660 | |
| 2661 Emacs' normal undo system allows you to undo an arbitrary | |
| 2662 number of buffer changes. These undos are recorded as ordinary | |
| 2663 buffer changes themselves. So when you break the chain of | |
| 2664 undos by issuing some other command, you can then undo all | |
| 2665 the undos. The chain of recorded buffer modifications | |
| 2666 therefore grows without bound, truncated only at garbage | |
| 2667 collection time. | |

| 2672 Lisp Package Authors | |
| 2673 ==================== | |
| 2674 Reporter was written primarily for Emacs Lisp package authors so | |
| 2675 that their users can easily report bugs. When invoked, | |
| 2676 reporter-submit-bug-report will set up an outgoing mail buffer with | |
| 2677 the appropriate bug report address, including a lisp expression the | |
| 2678 maintainer of the package can eval to completely reproduce the | |
| 2679 environment in which the bug was observed (e.g. by using | |
| 2680 eval-last-sexp). This package proved especially useful during my | |
| 2681 development of cc-mode, which is highly dependent on its | |
| 2682 configuration variables. | |

| 2731 | |
| 2732 Our basic structure is the queue/process/buffer triple. Each entry | |
| 2733 of the queue is a regexp/closure/function triple. We buffer | |
| 2734 bytes from the process until we see the regexp at the head of the | |

| 2748 | |
| 2749 Emacs's standard method for making buffer names unique adds <2>, <3>, | |
| 2750 etc. to the end of (all but one of) the buffers. This file replaces | |
| 2751 that behavior, for buffers visiting files and dired buffers, with a | |
| 2752 uniquification that adds parts of the file name until the buffer names | |
| 2753 are unique. For instance, buffers visiting /u/mernst/tmp/Makefile and | |
| 2754 /usr/projects/zaphod/Makefile would be named Makefile|tmp and | |
| 2755 Makefile|zaphod, respectively (instead of Makefile and Makefile<2>). | |
| 2756 Other buffer name styles are also available. | |

| 2812 * What Changed | |
| 2813 =================== | |
| 2814 | |
| 2815 | |
| 2816 ** Differences between XEmacs and GNU Emacs 19 | |
| 2817 ================================================== | |
| 2818 | |
| 2819 In XEmacs, events are first-class objects. FSF 19 represents them as | |
| 2820 integers, which obscures the differences between a key gesture and the | |
| 2821 ancient ASCII code used to represent a particular overlapping subset of them. | |
| 2822 | |
| 2823 In XEmacs, keymaps are first-class opaque objects. FSF 19 represents them as | |
| 2824 complicated combinations of association lists and vectors. If you use the | |
| 2825 advertised functional interface to manipulation of keymaps, the same code | |
| 2826 will work in XEmacs, Emacs 18, and GNU Emacs 19; if your code depends | |
| 2827 on the underlying implementation of keymaps, it will not. | |
| 2828 | |
| 2829 XEmacs uses "extents" to represent all non-textual aspects of buffers; | |
| 2830 FSF 19 uses two distinct objects, "text properties" and "overlays", | |
| 2831 which divide up the functionality between them. Extents are a | |
| 2832 superset of the functionality of the two FSF data types. The full FSF | |
| 2833 19 interface to text properties is supported in XEmacs (with extents | |
| 2834 being the underlying representation). | |
| 2835 | |
| 2836 Extents can be made to be copied into strings, and thus restored by kill | |
| 2837 and yank. Thus, one can specify this behavior on either "extents" or | |
| 2838 "text properties", whereas in FSF 19 text properties always have this | |
| 2839 behavior and overlays never do. | |
| 2840 | |
| 2841 Many more packages are provided standard with XEmacs than with FSF 19. | |
| 2842 | |
| 2843 Pixmaps of arbitrary size can be embedded in a buffer. | |
| 2844 | |
| 2845 Variable width fonts work. | |
| 2846 | |
| 2847 The height of a line is the height of the tallest font on that line, instead | |
| 2848 of all lines having the same height. | |
| 2849 | |
| 2850 XEmacs uses the MIT "Xt" toolkit instead of raw Xlib calls, which | |
| 2851 makes it be a more well-behaved X citizen (and also improves | |
| 2852 portability). A result of this is that it is possible to include | |
| 2853 other Xt "Widgets" in the XEmacs window. Also, XEmacs understands the | |
| 2854 standard Xt command-line arguments. | |
| 2855 | |
| 2856 XEmacs provides support for ToolTalk on systems that have it. | |
| 2857 | |
| 2858 XEmacs can ask questions using popup dialog boxes. Any command executed from | |
| 2859 a menu will ask yes/no questions with dialog boxes, while commands executed | |
| 2860 via the keyboard will use the minibuffer. | |
| 2861 | |
| 2862 XEmacs has a built-in toolbar. Four toolbars can actually be configured: | |
| 2863 top, bottom, left, and right toolbars. | |
| 2864 | |
| 2865 XEmacs has vertical and horizontal scrollbars. Unlike in FSF 19 (which | |
| 2866 provides a primitive form of vertical scrollbar), these are true toolkit | |
| 2867 scrollbars. A look-alike Motif scrollbar is provided for those who | |
| 2868 don't have Motif. (Even for those who do, the look-alike may be preferable | |
| 2869 as it is faster.) | |
| 2870 | |
| 2871 If you're running on a machine with audio hardware, you can specify sound | |
| 2872 files for XEmacs to play instead of the default X beep. See the documentation | |
| 2873 of the function load-sound-file and the variable sound-alist. | |
| 2874 | |
| 2875 An XEmacs frame can be placed within an "external client widget" managed by | |
| 2876 another application. This allows an application to use an XEmacs frame as its | |
| 2877 text pane rather than the standard Text widget that is provided with Motif or | |
| 2878 Athena. XEmacs supports Motif applications, generic Xt (e.g. Athena) | |
| 2879 applications, and raw Xlib applications. | |
| 2880 | |
| 2881 Here are some more specifics about the XEmacs implementation: | |
| 2882 | |
| 2883 *** The Input Model | |
| 2884 ------------------- | |
| 2885 | |
| 2886 The fundamental unit of input is an "event" instead of a character. An | |
| 2887 event is a new data type that contains several pieces of information. | |
| 2888 There are several kinds of event, and corresponding accessor and utility | |
| 2889 functions. We tried to abstract them so that they would apply equally | |
| 2890 well to a number of window systems. | |
| 2891 | |
| 2892 NOTE: All timestamps are measured as milliseconds since Emacs started. | |
| 2893 | |
| 2894 key_press_event | |
| 2895 event_channel A token representing which keyboard generated it. | |
| 2896 For this kind of event, this is a frame object. | |
| 2897 (This is for eventual support of multiple displays.) | |
| 2898 timestamp When it happened | |
| 2899 key What keysym this is; an integer or a symbol. | |
| 2900 If this is an integer, it will be in the printing | |
| 2901 ASCII range: >32 and <127. | |
| 2902 modifiers Bucky-bits on that key: control, meta, etc. | |
| 2903 For most keys, Shift is not a bit; that is implicit | |
| 2904 in the keyboard layout. | |
| 2905 | |
| 2906 button_press_event | |
| 2907 button_release_event | |
| 2908 event_channel A token representing which mouse generated it. | |
| 2909 For this kind of event, this is a frame object. | |
| 2910 timestamp When it happened | |
| 2911 button What button went down or up. | |
| 2912 modifiers Bucky-bits on that button: shift, control, meta, etc. | |
| 2913 x, y Where it was at the button-state-change (in pixels). | |
| 2914 | |
| 2915 pointer_motion_event | |
| 2916 event_channel A token representing which mouse generated it. | |
| 2917 For this kind of event, this is a frame object. | |
| 2918 timestamp When it happened | |
| 2919 x, y Where it was after it moved (in pixels). | |
| 2920 modifiers Bucky-bits down when the motion was detected. | |
| 2921 (Possibly not all window systems will provide this?) | |
| 2922 | |
| 2923 process_event | |
| 2924 timestamp When it happened | |
| 2925 process the emacs "process" object in question | |
| 2926 | |
| 2927 timeout_event | |
| 2928 timestamp Now (really, when the timeout was signaled) | |
| 2929 interval_id The ID returned when the associated call to | |
| 2930 add_timeout_cb() was made | |
| 2931 ------ the rest of the fields are filled in by Emacs ----- | |
| 2932 id_number The Emacs timeout ID for this timeout (more | |
| 2933 than one timeout event can have the same value | |
| 2934 here, since Emacs timeouts, as opposed to | |
| 2935 add_timeout_cb() timeouts, can resignal | |
| 2936 themselves) | |
| 2937 function An elisp function to call when this timeout is | |
| 2938 processed. | |
| 2939 object The object passed to that function. | |
| 2940 | |
| 2941 eval_event | |
| 2942 timestamp When it happened | |
| 2943 function An elisp function to call with this event object. | |
| 2944 object Anything. | |
| 2945 This kind of event is used internally; sometimes the | |
| 2946 window system interface would like to inform emacs of | |
| 2947 some user action (such as focusing on another frame) | |
| 2948 but needs that to happen synchronously with the other | |
| 2949 user input, like keypresses. This is useful when | |
| 2950 events are reported through callbacks rather | |
| 2951 than in the standard event stream. | |
| 2952 | |
| 2953 misc_user_event | |
| 2954 timestamp When it happened | |
| 2955 function An elisp function to call with this event object. | |
| 2956 object Anything. | |
| 2957 This is similar to an eval_event, except that it is | |
| 2958 generated by user actions: selections in the | |
| 2959 menubar or scrollbar actions. It is a "command" | |
| 2960 event, like key and mouse presses (and unlike mouse | |
| 2961 motion, process output, and enter and leave window | |
| 2962 hooks). In many ways, eval_events are not the same | |
| 2963 as keypresses or misc_user_events. | |
| 2964 | |
| 2965 magic_event | |
| 2966 No user-serviceable parts within. This is for things | |
| 2967 like KeymapNotify and ExposeRegion events and so on | |
| 2968 that emacs itself doesn't care about, but which it | |
| 2969 must do something with for proper interaction with | |
| 2970 the window system. | |
| 2971 | |
| 2972 Magic_events are handled somewhat asynchronously, just | |
| 2973 like subprocess filters. However, occasionally a | |
| 2974 magic_event needs to be handled synchronously; in that | |
| 2975 case, the asynchronous handling of the magic_event will | |
| 2976 push an eval_event back onto the queue, which will be | |
| 2977 handled synchronously later. This is one of the | |
| 2978 reasons why eval_events exist; I'm not entirely happy | |
| 2979 with this aspect of this event model. | |
| 2980 | |
| 2981 | |
| 2982 The function `next-event' blocks and returns one of the above-described | |
| 2983 event objects. The function `dispatch-event' takes an event and processes | |
| 2984 it in the appropriate way. | |
| 2985 | |
| 2986 For a process-event, dispatch-event calls the process's handler; for a | |
| 2987 mouse-motion event, the mouse-motion-handler hook is called, and so on. | |
| 2988 For magic-events, dispatch-event does window-system-dependent things, | |
| 2989 including calling some non-window-system-dependent hooks: map-frame-hook, | |
| 2990 unmap-frame-hook, mouse-enter-frame-hook, and mouse-leave-frame-hook. | |
| 2991 | |
| 2992 The function `next-command-event' calls `next-event' until it gets a key or | |
| 2993 button from the user (that is, not a process, motion, timeout, or magic | |
| 2994 event). If it gets an event that is not a key or button, it calls | |
| 2995 `dispatch-event' on it immediately and reads another one. The | |
| 2996 next-command-event function could be implemented in Emacs Lisp, though it | |
| 2997 isn't. Generally one should call `next-command-event' instead of | |
| 2998 `next-event'. | |
| 2999 | |
| 3000 read-char calls next-command-event; if it doesn't get an event that can be | |
| 3001 converted to an ASCII character, it signals an error. Otherwise it returns | |
| 3002 an integer. | |
| 3003 | |
| 3004 The variable `last-command-char' always contains an integer, or nil (if the | |
| 3005 last read event has no ASCII equivalent, as when it is a mouse-click or a | |
| 3006 non-ASCII character chord.) | |
| 3007 | |
| 3008 The new variable `last-command-event' holds an event object, that could be | |
| 3009 a non-ASCII character, a button click, a menu selection, etc. | |
| 3010 | |
| 3011 The variable `unread-command-char' no longer exists, and has been replaced | |
| 3012 by `unread-command-events'. With the new event model, it is incorrect for | |
| 3013 code to do (setq unread-command-char (read-char)), because all user-input | |
| 3014 can't be represented as ASCII characters. *** This is an incompatible | |
| 3015 change. Code which sets `unread-command-char' must be updated to use the | |
| 3016 combination of `next-command-event' and `unread-command-events' instead. | |
| 3017 | |
| 3018 The functions `this-command-keys' and `recent-keys' return a vector of | |
| 3019 event objects, instead of a string of ASCII characters. *** This also | |
| 3020 is an incompatible change. | |
| 3021 | |
| 3022 Almost nothing happens at interrupt level; the SIGIO handler simply sets a | |
| 3023 flag, and later, the X event queue is scanned for KeyPress events which map | |
| 3024 to ^G. All redisplay happens in the main thread of the process. | |
| 3025 | |
| 3026 | |
| 3027 *** Keymaps | |
| 3028 ----------- | |
| 3029 | |
| 3030 Instead of keymaps being alists or obarrays, they are a new primary data | |
| 3031 type. The only user access to the contents of a keymap is through the | |
| 3032 existing keymap-manipulation functions, and a new function, map-keymap. | |
| 3033 This means that existing code that manipulates keymaps may need to | |
| 3034 be changed. | |
| 3035 | |
| 3036 One of our goals with the new input and keymap code was to make more | |
| 3037 character combinations available for binding, besides just ASCII and | |
| 3038 function keys. We want to be able bind different commands to Control-a | |
| 3039 and Control-Shift-a; we also want it to be possible for the keys Control-h | |
| 3040 and Backspace (and Control-M and Return, and Control-I and Tab, etc) to | |
| 3041 be distinct. | |
| 3042 | |
| 3043 One of the most common complaints that new Emacs users have is that backspace | |
| 3044 is help. The answer is to play around with the keyboard-translate-table, or | |
| 3045 be lucky enough to have a system administrator who has done this for you | |
| 3046 already; but if it were possible to bind backspace and C-h to different | |
| 3047 things, then (under a window manager at least) both backspace and delete | |
| 3048 would delete a character, and ^H would be help. There's no need to deal | |
| 3049 with xmodmap, kbd-translate-table, etc. | |
| 3050 | |
| 3051 Here are some more examples: suppose you want to bind one function to Tab, | |
| 3052 and another to Control-Tab. This can't be done if Tab and Control-I are the | |
| 3053 same thing. What about control keys that have no ASCII equivalent, like | |
| 3054 Control-< ? One might want that to be bound to set-mark-at-point-min. We | |
| 3055 want M-C-Backspace to be kill-backward-sexp. But we want M-Backspace to be | |
| 3056 kill-backward-word. Again, this can't be done if Backspace and C-h are | |
| 3057 indistinguishable. | |
| 3058 | |
| 3059 The user represents keys as a string of ASCII characters (when possible and | |
| 3060 convenient), or as a vector of event objects, or as a vector of "key | |
| 3061 description lists", that looks like (control a), or (control meta delete) | |
| 3062 or (shift f1). The order of the modifier-names is not significant, so | |
| 3063 (meta control x) and (control meta x) are the same. | |
| 3064 | |
| 3065 `define-key' knows how to take any of the above representations and store them | |
| 3066 into a keymap. When Emacs wants to return a key sequence (this-command-keys, | |
| 3067 recent-keys, keyboard-macros, and read-key-sequence, for example) it returns | |
| 3068 a vector of event objects. Keyboard macros can also be represented as ASCII | |
| 3069 strings or as vectors of key description lists. | |
| 3070 | |
| 3071 This is an incompatible change: code which calls `this-command-keys', | |
| 3072 `recent-keys', `read-key-sequence', or manipulates keyboard-macros probably | |
| 3073 needs to be changed so that it no longer assumes that the returned value is a | |
| 3074 string. | |
| 3075 | |
| 3076 Control-Shift-a is specified as (control A), not (control shift a), since A | |
| 3077 is a two-case character. But for keys that don't have an upper case | |
| 3078 version, like F1, Backspace, and Escape, you use the (shift backspace) syntax. | |
| 3079 | |
| 3080 See the doc string for our version of define-key, reproduced below in the | |
| 3081 `Changed Functions' section. Note that when the KEYS argument is a string, | |
| 3082 it has the same semantics as the v18 define-key. | |
| 3083 | |
| 3084 | |
| 3085 *** Xt Integration | |
| 3086 ------------------ | |
| 3087 | |
| 3088 The heart of the event loop is implemented in terms of the Xt event functions | |
| 3089 (specifically XtAppProcessEvent), and uses Xt's concept of timeouts and | |
| 3090 file-descriptor callbacks, eliminating a large amount of system-dependent code | |
| 3091 (Xt does it for you.) | |
| 3092 | |
| 3093 If Emacs is compiled with support for X, it uses the Xt event loop even when | |
| 3094 Emacs is not running on an X display (the Xt event loop supports this). This | |
| 3095 makes it possible to run Emacs on a dumb TTY, and later connect it to one or | |
| 3096 more X servers. It should also be possible to later connect an existing Emacs | |
| 3097 process to additional TTY's, although this code is still experimental. (Our | |
| 3098 intent at this point is not to have an Emacs that is being used by multiple | |
| 3099 people at the same time: it is to make it possible for someone to go home, log | |
| 3100 in on a dialup line, and connect to the same Emacs process that is running | |
| 3101 under X in their office without having to recreate their buffer state and so | |
| 3102 on.) | |
| 3103 | |
| 3104 If Emacs is not compiled with support for X, then it instead uses more general | |
| 3105 code, something like what v18 does; but this way of doing things is a lot more | |
| 3106 modular. | |
| 3107 | |
| 3108 (Linking Emacs with Xt seems to only add about 300k to the executable size, | |
| 3109 compared with an Emacs linked with Xlib only.) | |
| 3110 | |
| 3111 | |
| 3112 *** Region Highlighting | |
| 3113 ----------------------- | |
| 3114 | |
| 3115 If the variable `zmacs-regions' is true, then the region between point and | |
| 3116 mark will be highlighted when "active". Those commands which push a mark | |
| 3117 (such as C-SPC, and C-x C-x) make the region become "active" and thus | |
| 3118 highlighted. Most commands (all non-motion commands, basically) cause it to | |
| 3119 become non-highlighted (non-"active"). Commands that operate on the region | |
| 3120 (such as C-w, C-x C-l, etc.) only work if the region is in the highlighted | |
| 3121 state. | |
| 3122 | |
| 3123 zmacs-activate-region-hook and zmacs-deactivate-region-hook are run at the | |
| 3124 appropriate times; under X, zmacs-activate-region-hook makes the X selection | |
| 3125 be the region between point and mark, thus doing two things at once: making | |
| 3126 the region and the X selection be the same; and making the region highlight | |
| 3127 in the same way as the X selection. | |
| 3128 | |
| 3129 If `zmacs-regions' is true, then the `mark-marker' command returns nil unless | |
| 3130 the region is currently in the active (highlighted) state. With an argument | |
| 3131 of t, this returns the mark (if there is one) regardless of the active-region | |
| 3132 state. You should *generally* not use the mark unless the region is active, | |
| 3133 if the user has expressed a preference for the active-region model. Watch | |
| 3134 out! Moving this marker changes the mark position. If you set the marker not | |
| 3135 to point anywhere, the buffer will have no mark. | |
| 3136 | |
| 3137 In this way, the primary selection is a fairly transitory entity; but | |
| 3138 when something is copied to the kill ring, it is made the Clipboard | |
| 3139 selection. It is also stored into CUT_BUFFER0, for compatibility with | |
| 3140 X applications that don't understand selections (like Emacs18). | |
| 3141 | |
| 3142 Compatibility note: if you have code which uses (mark) or (mark-marker), | |
| 3143 then you need to either: change those calls to (mark t) or (mark-marker t); | |
| 3144 or simply bind `zmacs-regions' to nil around the call to mark or mark-marker. | |
| 3145 This is probably the best solution, since it will work in Emacs 18 as well. | |
| 3146 | |
| 3147 | |
| 3148 *** Menubars and Dialog Boxes | |
| 3149 ----------------------------- | |
| 3150 | |
| 3151 Here is an example of a menubar definition: | |
| 3152 | |
| 3153 (defvar default-menubar | |
| 3154 '(("File" ["Open File..." find-file t] | |
| 3155 ["Save Buffer" save-buffer t] | |
| 3156 ["Save Buffer As..." write-file t] | |
| 3157 ["Revert Buffer" revert-buffer t] | |
| 3158 "-----" | |
| 3159 ["Print Buffer" lpr-buffer t] | |
| 3160 "-----" | |
| 3161 ["Delete Frame" delete-frame t] | |
| 3162 ["Kill Buffer..." kill-buffer t] | |
| 3163 ["Exit Emacs" save-buffers-kill-emacs t] | |
| 3164 ) | |
| 3165 ("Edit" ["Undo" advertised-undo t] | |
| 3166 ["Cut" kill-primary-selection t] | |
| 3167 ["Copy" copy-primary-selection t] | |
| 3168 ["Paste" yank-clipboard-selection t] | |
| 3169 ["Clear" delete-primary-selection t] | |
| 3170 ) | |
| 3171 ...)) | |
| 3172 | |
| 3173 The first element of each menu item is the string to print on the menu. | |
| 3174 | |
| 3175 The second element is the callback function; if it is a symbol, it is | |
| 3176 invoked with `call-interactively.' If it is a list, it is invoked with | |
| 3177 `eval'. | |
| 3178 | |
| 3179 If the second element is a symbol, then the menu also displays the key that | |
| 3180 is bound to that command (if any). | |
| 3181 | |
| 3182 The third element of the menu items determines whether the item is selectable. | |
| 3183 It may be t, nil, or a form to evaluate. Also, a hook is run just before a | |
| 3184 menu is exposed, which can be used to change the value of these slots. | |
| 3185 For example, there is a hook that makes the "undo" menu item be selectable | |
| 3186 only in the cases when `advertised-undo' would not signal an error. | |
| 3187 | |
| 3188 Menus may have other menus nested within them; they will cascade. | |
| 3189 | |
| 3190 There are utility functions for adding items to menus, deleting items, | |
| 3191 disabling them, etc. | |
| 3192 | |
| 3193 The function `popup-menu' takes a menu description and pops it up. | |
| 3194 | |
| 3195 The function `popup-dialog-box' takes a dialog-box description and pops | |
| 3196 it up. Dialog box descriptions look a lot like menu descriptions. | |
| 3197 | |
| 3198 The menubar, menu, and dialog-box code is implemented as a library, | |
| 3199 with an interface which hides the toolkit that implements it. | |
| 3200 | |
| 3201 | |
| 3202 *** Isearch Changes | |
| 3203 ------------------- | |
| 3204 | |
| 3205 Isearch has been reimplemented in a different way, adding some new features, | |
| 3206 and causing a few incompatible changes. | |
| 3207 | |
| 3208 - the old isearch-*-char variables are no longer supported. In the old | |
| 3209 system, one could make ^A mean "repeat the search" by doing something | |
| 3210 like (setq search-repeat-char ?C-a). In the new system, this is | |
| 3211 accomplished with | |
| 3212 | |
| 3213 (define-key isearch-mode-map "\C-a" 'isearch-repeat-forward) | |
| 3214 | |
| 3215 - The advantage of using the normal keymap mechanism for this is that you | |
| 3216 can bind more than one key to an isearch command: for example, both C-a | |
| 3217 and C-s could do the same thing inside isearch mode. You can also bind | |
| 3218 multi-key sequences inside of isearch mode, and bind non-ASCII keys. | |
| 3219 For example, to use the F1 key to terminate a search: | |
| 3220 | |
| 3221 (define-key isearch-mode-map 'f1 'isearch-exit) | |
| 3222 | |
| 3223 or to make ``C-c C-c'' terminate a search: | |
| 3224 | |
| 3225 (define-key isearch-mode-map "\C-c\C-c" 'isearch-exit) | |
| 3226 | |
| 3227 - If isearch is behaving case-insensitively (the default) and you type an | |
| 3228 upper case character, then the search will become case-sensitive. This | |
| 3229 can be disabled by setting `search-caps-disable-folding' to nil. | |
| 3230 | |
| 3231 - There is a history ring of the strings previously searched for; typing | |
| 3232 M-p or M-n while searching will cycle through this ring. Typing M-TAB | |
| 3233 will do completion across the set of items in the history ring. | |
| 3234 | |
| 3235 - The ESC key is no longer used to terminate an incremental search. The | |
| 3236 RET key should be used instead. This change is necessary for it to be | |
| 3237 possible to bind "meta" characters to isearch commands. | |
| 3238 | |
| 3239 | |
| 3240 *** Startup Code Changes | |
| 3241 ------------------------ | |
| 3242 | |
| 3243 The initial X frame is mapped before the user's .emacs file is executed. | |
| 3244 Without this, there is no way for the user to see any error messages | |
| 3245 generated by their .emacs file, any windows created by the .emacs file | |
| 3246 don't show up, and the copyleft notice isn't shown. | |
| 3247 | |
| 3248 The default values for load-path, exec-path, lock-directory, and | |
| 3249 Info-directory-list are not (necessarily) built into Emacs, but are | |
| 3250 computed at startup time. | |
| 3251 | |
| 3252 First, Emacs looks at the directory in which its executable file resides: | |
| 3253 | |
| 3254 o If that directory contains subdirectories named "lisp" and "lib-src", | |
| 3255 then those directories are used as the lisp library and exec directory. | |
| 3256 | |
| 3257 o If the parent of the directory in which the emacs executable is located | |
| 3258 contains "lisp" and "lib-src" subdirectories, then those are used. | |
| 3259 | |
| 3260 o If ../lib/xemacs-<version> (starting from the directory in which the | |
| 3261 emacs executable is located) contains a "lisp" subdirectory and either | |
| 3262 a "lib-src" subdirectory or a <configuration-name> subdirectory, then | |
| 3263 those are used. | |
| 3264 | |
| 3265 o If the emacs executable that was run is a symbolic link, then the link | |
| 3266 is chased, and the resultant directory is checked as above. | |
| 3267 | |
| 3268 (Actually, it doesn't just look for "lisp/", it looks for "lisp/prim/", | |
| 3269 which reduces the chances of a false positive.) | |
| 3270 | |
| 3271 If the lisp directory contains subdirectories, they are added to the default | |
| 3272 load-path as well. If the site-lisp directory exists and contains | |
| 3273 subdirectories, they are then added. Subdirectories whose names begin with | |
| 3274 a dot or a hyphen are not added to the load-path. | |
| 3275 | |
| 3276 These heuristics fail if the Emacs binary was copied from the main Emacs | |
| 3277 tree to some other directory, and links for the lisp directory were not put | |
| 3278 in. This isn't much of a restriction: either make there be subdirectories | |
| 3279 (or symbolic links) of the directory of the emacs executable, or make the | |
| 3280 "installed" emacs executable be a symbolic link to an executable in a more | |
| 3281 appropriate directory structure. For example, this setup works: | |
| 3282 | |
| 3283 /usr/local/xemacs/xemacs* ; The executable. | |
| 3284 /usr/local/xemacs/lisp/ ; The associated directories. | |
| 3285 /usr/local/xemacs/etc/ ; Any of the files in this list | |
| 3286 /usr/local/xemacs/lock/ ; could be symbolic links as well. | |
| 3287 /usr/local/xemacs/info/ | |
| 3288 | |
| 3289 As does this: | |
| 3290 | |
| 3291 /usr/local/bin/xemacs -> ../xemacs/src/xemacs-19.14 ; A link... | |
| 3292 /usr/local/xemacs/src/xemacs-19.14* ; The executable, | |
| 3293 /usr/local/xemacs/lisp/ ; and the rest of | |
| 3294 /usr/local/xemacs/etc/ ; the source tree | |
| 3295 /usr/local/xemacs/lock/ | |
| 3296 /usr/local/xemacs/info/ | |
| 3297 | |
| 3298 This configuration might be used for a multi-architecture installation; assume | |
| 3299 that $LOCAL refers to a directory which contains only files specific to a | |
| 3300 particular architecture (i.e., executables) and $SHARED refers to those files | |
| 3301 which are not machine specific (i.e., lisp code and documentation.) | |
| 3302 | |
| 3303 $LOCAL/bin/xemacs@ -> $LOCAL/xemacs-19.14/xemacs* | |
| 3304 $LOCAL/xemacs-19.14/lisp@ -> $SHARED/xemacs-19.14/lisp/ | |
| 3305 $LOCAL/xemacs-19.14/etc@ -> $SHARED/xemacs-19.14/etc/ | |
| 3306 $LOCAL/xemacs-19.14/info@ -> $SHARED/xemacs-19.14/info/ | |
| 3307 | |
| 3308 The following would also work, but the above is probably more attractive: | |
| 3309 | |
| 3310 $LOCAL/bin/xemacs* | |
| 3311 $LOCAL/bin/lisp@ -> $SHARED/xemacs-19.14/lisp/ | |
| 3312 $LOCAL/bin/etc@ -> $SHARED/xemacs-19.14/etc/ | |
| 3313 $LOCAL/bin/info@ -> $SHARED/xemacs-19.14/info/ | |
| 3314 | |
| 3315 If Emacs can't find the requisite directories, it writes a message like this | |
| 3316 (or some appropriate subset of it) to stderr: | |
| 3317 | |
| 3318 WARNING: | |
| 3319 couldn't find an obvious default for load-path, exec-directory, and | |
| 3320 lock-directory, and there were no defaults specified in paths.h when | |
| 3321 Emacs was built. Perhaps some directories don't exist, or the Emacs | |
| 3322 executable, /cadillac-th/jwz/somewhere/xemacs is in a strange place? | |
| 3323 | |
| 3324 Without both exec-directory and load-path, Emacs will be very broken. | |
| 3325 Consider making a symbolic link from /cadillac-th/jwz/somewhere/etc | |
| 3326 to wherever the appropriate Emacs etc/ directory is, and from | |
| 3327 /cadillac-th/jwz/somewhere/lisp/ to wherever the appropriate Emacs | |
| 3328 lisp library is. | |
| 3329 | |
| 3330 Without lock-directory set, file locking won't work. Consider | |
| 3331 creating /cadillac-th/jwz/somewhere/lock as a directory or symbolic | |
| 3332 link for use as the lock directory. | |
| 3333 | |
| 3334 The default installation tree is the following: | |
| 3335 | |
| 3336 /usr/local/bin/b2m ; | |
| 3337 ctags ; executables that | |
| 3338 emacsclient ; should be in | |
| 3339 etags ; user's path | |
| 3340 xemacs -> xemacs-<version> ; | |
| 3341 xemacs ; | |
| 3342 /usr/local/lib/xemacs/site-lisp | |
| 3343 /usr/local/lib/xemacs/lock | |
| 3344 /usr/local/lib/xemacs-<version>/etc ; architecture ind. files | |
| 3345 /usr/local/lib/xemacs-<version>/info | |
| 3346 /usr/local/lib/xemacs-<version>/lisp | |
| 3347 /usr/local/lib/xemacs-<version>/<configuration> ; binaries emacs may run | |
| 3348 | |
| 3349 | |
| 3350 *** X Resources | |
| 3351 --------------- | |
| 3352 | |
| 3353 (Note: This section is copied verbatim from the XEmacs Reference Manual.) | |
| 3354 | |
| 3355 The Emacs resources are generally set per-frame. Each Emacs frame | |
| 3356 can have its own name or the same name as another, depending on the | |
| 3357 name passed to the `make-frame' function. | |
| 3358 | |
| 3359 You can specify resources for all frames with the syntax: | |
| 3360 | |
| 3361 Emacs*parameter: value | |
| 3362 | |
| 3363 or | |
| 3364 | |
| 3365 Emacs*EmacsFrame.parameter:value | |
| 3366 | |
| 3367 You can specify resources for a particular frame with the syntax: | |
| 3368 | |
| 3369 Emacs*FRAME-NAME.parameter: value | |
| 3370 | |
| 3371 | |
| 3372 **** Geometry Resources | |
| 3373 ----------------------- | |
| 3374 | |
| 3375 To make the default size of all Emacs frames be 80 columns by 55 | |
| 3376 lines, do this: | |
| 3377 | |
| 3378 Emacs*EmacsFrame.geometry: 80x55 | |
| 3379 | |
| 3380 To set the geometry of a particular frame named `fred', do this: | |
| 3381 | |
| 3382 Emacs*fred.geometry: 80x55 | |
| 3383 | |
| 3384 Important! Do not use the following syntax: | |
| 3385 | |
| 3386 Emacs*geometry: 80x55 | |
| 3387 | |
| 3388 You should never use `*geometry' with any X application. It does not | |
| 3389 say "make the geometry of Emacs be 80 columns by 55 lines." It really | |
| 3390 says, "make Emacs and all subwindows thereof be 80x55 in whatever units | |
| 3391 they care to measure in." In particular, that is both telling the | |
| 3392 Emacs text pane to be 80x55 in characters, and telling the menubar pane | |
| 3393 to be 80x55 pixels, which is surely not what you want. | |
| 3394 | |
| 3395 As a special case, this geometry specification also works (and sets | |
| 3396 the default size of all Emacs frames to 80 columns by 55 lines): | |
| 3397 | |
| 3398 Emacs.geometry: 80x55 | |
| 3399 | |
| 3400 since that is the syntax used with most other applications (since most | |
| 3401 other applications have only one top-level window, unlike Emacs). In | |
| 3402 general, however, the top-level shell (the unmapped ApplicationShell | |
| 3403 widget named `Emacs' that is the parent of the shell widgets that | |
| 3404 actually manage the individual frames) does not have any interesting | |
| 3405 resources on it, and you should set the resources on the frames instead. | |
| 3406 | |
| 3407 The `-geometry' command-line argument sets only the geometry of the | |
| 3408 initial frame created by Emacs. | |
| 3409 | |
| 3410 A more complete explanation of geometry-handling is | |
| 3411 | |
| 3412 * The `-geometry' command-line option sets the `Emacs.geometry' | |
| 3413 resource, that is, the geometry of the ApplicationShell. | |
| 3414 | |
| 3415 * For the first frame created, the size of the frame is taken from | |
| 3416 the ApplicationShell if it is specified, otherwise from the | |
| 3417 geometry of the frame. | |
| 3418 | |
| 3419 * For subsequent frames, the order is reversed: First the frame, and | |
| 3420 then the ApplicationShell. | |
| 3421 | |
| 3422 * For the first frame created, the position of the frame is taken | |
| 3423 from the ApplicationShell (`Emacs.geometry') if it is specified, | |
| 3424 otherwise from the geometry of the frame. | |
| 3425 | |
| 3426 * For subsequent frames, the position is taken only from the frame, | |
| 3427 and never from the ApplicationShell. | |
| 3428 | |
| 3429 This is rather complicated, but it does seem to provide the most | |
| 3430 intuitive behavior with respect to the default sizes and positions of | |
| 3431 frames created in various ways. | |
| 3432 | |
| 3433 | |
| 3434 **** Iconic Resources | |
| 3435 --------------------- | |
| 3436 | |
| 3437 Analogous to `-geometry', the `-iconic' command-line option sets the | |
| 3438 iconic flag of the ApplicationShell (`Emacs.iconic') and always applies | |
| 3439 to the first frame created regardless of its name. However, it is | |
| 3440 possible to set the iconic flag on particular frames (by name) by using | |
| 3441 the `Emacs*FRAME-NAME.iconic' resource. | |
| 3442 | |
| 3443 | |
| 3444 **** Resource List | |
| 3445 ------------------ | |
| 3446 | |
| 3447 Emacs frames accept the following resources: | |
| 3448 | |
| 3449 `geometry' (class `Geometry'): string | |
| 3450 Initial geometry for the frame. *Note Geometry Resources:: for a | |
| 3451 complete discussion of how this works. | |
| 3452 | |
| 3453 `iconic' (class `Iconic'): boolean | |
| 3454 Whether this frame should appear in the iconified state. | |
| 3455 | |
| 3456 `internalBorderWidth' (class `InternalBorderWidth'): int | |
| 3457 How many blank pixels to leave between the text and the edge of the | |
| 3458 window. | |
| 3459 | |
| 3460 `interline' (class `Interline'): int | |
| 3461 How many pixels to leave between each line (may not be | |
| 3462 implemented). | |
| 3463 | |
| 3464 `menubar' (class `Menubar'): boolean | |
| 3465 Whether newly-created frames should initially have a menubar. Set | |
| 3466 to true by default. | |
| 3467 | |
| 3468 `initiallyUnmapped' (class `InitiallyUnmapped'): boolean | |
| 3469 Whether XEmacs should leave the initial frame unmapped when it | |
| 3470 starts up. This is useful if you are starting XEmacs as a server | |
| 3471 (e.g. in conjunction with gnuserv or the external client widget). | |
| 3472 You can also control this with the `-unmapped' command-line option. | |
| 3473 | |
| 3474 `barCursor' (class `BarColor'): boolean | |
| 3475 Whether the cursor should be displayed as a bar, or the | |
| 3476 traditional box. | |
| 3477 | |
| 3478 `textPointer' (class `Cursor'): cursor-name | |
| 3479 The cursor to use when the mouse is over text. This resource is | |
| 3480 used to initialize the variable `x-pointer-shape'. | |
| 3481 | |
| 3482 `selectionPointer' (class `Cursor'): cursor-name | |
| 3483 The cursor to use when the mouse is over a selectable text region | |
| 3484 (an extent with the `highlight' property; for example, an Info | |
| 3485 cross-reference). This resource is used to initialize the variable | |
| 3486 `x-selection-pointer-shape'. | |
| 3487 | |
| 3488 `spacePointer' (class `Cursor'): cursor-name | |
| 3489 The cursor to use when the mouse is over a blank space in a buffer | |
| 3490 (that is, after the end of a line or after the end-of-file). This | |
| 3491 resource is used to initialize the variable | |
| 3492 `x-nontext-pointer-shape'. | |
| 3493 | |
| 3494 `modeLinePointer' (class `Cursor'): cursor-name | |
| 3495 The cursor to use when the mouse is over a mode line. This | |
| 3496 resource is used to initialize the variable `x-mode-pointer-shape'. | |
| 3497 | |
| 3498 `gcPointer' (class `Cursor'): cursor-name | |
| 3499 The cursor to display when a garbage-collection is in progress. | |
| 3500 This resource is used to initialize the variable | |
| 3501 `x-gc-pointer-shape'. | |
| 3502 | |
| 3503 `scrollbarPointer' (class `Cursor'): cursor-name | |
| 3504 The cursor to use when the mouse is over the scrollbar. This | |
| 3505 resource is used to initialize the variable | |
| 3506 `x-scrollbar-pointer-shape'. | |
| 3507 | |
| 3508 `pointerColor' (class `Foreground'): color-name | |
| 3509 `pointerBackground' (class `Background'): color-name | |
| 3510 The foreground and background colors of the mouse cursor. These | |
| 3511 resources are used to initialize the variables | |
| 3512 `x-pointer-foreground-color' and `x-pointer-background-color'. | |
| 3513 | |
| 3514 `scrollBarWidth' (class `ScrollBarWidth'): integer | |
| 3515 How wide the vertical scrollbars should be, in pixels; 0 means no | |
| 3516 vertical scrollbars. You can also use a resource specification of | |
| 3517 the form `*scrollbar.width', or the usual toolkit scrollbar | |
| 3518 resources: `*XmScrollBar.width' (Motif), `*XlwScrollBar.width' | |
| 3519 (Lucid), or `*Scrollbar.thickness' (Athena). We don't recommend | |
| 3520 that you use the toolkit resources, though, because they're | |
| 3521 dependent on how exactly your particular build of XEmacs was | |
| 3522 configured. | |
| 3523 | |
| 3524 `scrollBarHeight' (class `ScrollBarHeight'): integer | |
| 3525 How high the horizontal scrollbars should be, in pixels; 0 means no | |
| 3526 horizontal scrollbars. You can also use a resource specification | |
| 3527 of the form `*scrollbar.height', or the usual toolkit scrollbar | |
| 3528 resources: `*XmScrollBar.height' (Motif), `*XlwScrollBar.height' | |
| 3529 (Lucid), or `*Scrollbar.thickness' (Athena). We don't recommend | |
| 3530 that you use the toolkit resources, though, because they're | |
| 3531 dependent on how exactly your particular build of XEmacs was | |
| 3532 configured. | |
| 3533 | |
| 3534 `scrollBarPlacement' (class `ScrollBarPlacement'): string | |
| 3535 Where the horizontal and vertical scrollbars should be positioned. | |
| 3536 This should be one of the four strings `bottom-left', | |
| 3537 `bottom-right', `top-left', and `top-right'. Default is | |
| 3538 `bottom-right' for the Motif and Lucid scrollbars and | |
| 3539 `bottom-left' for the Athena scrollbars. | |
| 3540 | |
| 3541 `topToolBarHeight' (class `TopToolBarHeight'): integer | |
| 3542 `bottomToolBarHeight' (class `BottomToolBarHeight'): integer | |
| 3543 `leftToolBarWidth' (class `LeftToolBarWidth'): integer | |
| 3544 `rightToolBarWidth' (class `RightToolBarWidth'): integer | |
| 3545 Height and width of the four possible toolbars. | |
| 3546 | |
| 3547 `topToolBarShadowColor' (class `TopToolBarShadowColor'): color-name | |
| 3548 `bottomToolBarShadowColor' (class `BottomToolBarShadowColor'): color-name | |
| 3549 Color of the top and bottom shadows for the toolbars. NOTE: These | |
| 3550 resources do *not* have anything to do with the top and bottom | |
| 3551 toolbars (i.e. the toolbars at the top and bottom of the frame)! | |
| 3552 Rather, they affect the top and bottom shadows around the edges of | |
| 3553 all four kinds of toolbars. | |
| 3554 | |
| 3555 `topToolBarShadowPixmap' (class `TopToolBarShadowPixmap'): pixmap-name | |
| 3556 `bottomToolBarShadowPixmap' (class `BottomToolBarShadowPixmap'): pixmap-name | |
| 3557 Pixmap of the top and bottom shadows for the toolbars. If set, | |
| 3558 these resources override the corresponding color resources. NOTE: | |
| 3559 These resources do *not* have anything to do with the top and | |
| 3560 bottom toolbars (i.e. the toolbars at the top and bottom of the | |
| 3561 frame)! Rather, they affect the top and bottom shadows around the | |
| 3562 edges of all four kinds of toolbars. | |
| 3563 | |
| 3564 `toolBarShadowThickness' (class `ToolBarShadowThickness'): integer | |
| 3565 Thickness of the shadows around the toolbars, in pixels. | |
| 3566 | |
| 3567 `visualBell' (class `VisualBell'): boolean | |
| 3568 Whether XEmacs should flash the screen rather than making an | |
| 3569 audible beep. | |
| 3570 | |
| 3571 `bellVolume' (class `BellVolume'): integer | |
| 3572 Volume of the audible beep. | |
| 3573 | |
| 3574 `useBackingStore' (class `UseBackingStore'): boolean | |
| 3575 Whether XEmacs should set the backing-store attribute of the X | |
| 3576 windows it creates. This increases the memory usage of the X | |
| 3577 server but decreases the amount of X traffic necessary to update | |
| 3578 the screen, and is useful when the connection to the X server goes | |
| 3579 over a low-bandwidth line such as a modem connection. | |
| 3580 | |
| 3581 | |
| 3582 **** Face Resources | |
| 3583 ------------------- | |
| 3584 | |
| 3585 The attributes of faces are also per-frame. They can be specified as: | |
| 3586 | |
| 3587 Emacs.FACE_NAME.parameter: value | |
| 3588 | |
| 3589 (*do not* use `Emacs*FACE_NAME...') | |
| 3590 | |
| 3591 or | |
| 3592 | |
| 3593 Emacs*FRAME_NAME.FACE_NAME.parameter: value | |
| 3594 | |
| 3595 Faces accept the following resources: | |
| 3596 | |
| 3597 `attributeFont' (class `AttributeFont'): font-name | |
| 3598 The font of this face. | |
| 3599 | |
| 3600 `attributeForeground' (class `AttributeForeground'): color-name | |
| 3601 `attributeBackground' (class `AttributeBackground'): color-name | |
| 3602 The foreground and background colors of this face. | |
| 3603 | |
| 3604 `attributeBackgroundPixmap' (class `AttributeBackgroundPixmap'): file-name | |
| 3605 The name of an XBM file (or XPM file, if your version of Emacs | |
| 3606 supports XPM), to use as a background stipple. | |
| 3607 | |
| 3608 `attributeUnderline' (class `AttributeUnderline'): boolean | |
| 3609 Whether text in this face should be underlined. | |
| 3610 | |
| 3611 All text is displayed in some face, defaulting to the face named | |
| 3612 `default'. To set the font of normal text, use | |
| 3613 `Emacs*default.attributeFont'. To set it in the frame named `fred', use | |
| 3614 `Emacs*fred.default.attributeFont'. | |
| 3615 | |
| 3616 These are the names of the predefined faces: | |
| 3617 | |
| 3618 `default' | |
| 3619 Everything inherits from this. | |
| 3620 | |
| 3621 `bold' | |
| 3622 If this is not specified in the resource database, Emacs tries to | |
| 3623 find a bold version of the font of the default face. | |
| 3624 | |
| 3625 `italic' | |
| 3626 If this is not specified in the resource database, Emacs tries to | |
| 3627 find an italic version of the font of the default face. | |
| 3628 | |
| 3629 `bold-italic' | |
| 3630 If this is not specified in the resource database, Emacs tries to | |
| 3631 find a bold-italic version of the font of the default face. | |
| 3632 | |
| 3633 `modeline' | |
| 3634 This is the face that the modeline is displayed in. If not | |
| 3635 specified in the resource database, it is determined from the | |
| 3636 default face by reversing the foreground and background colors. | |
| 3637 | |
| 3638 `highlight' | |
| 3639 This is the face that highlighted extents (for example, Info | |
| 3640 cross-references and possible completions, when the mouse passes | |
| 3641 over them) are displayed in. | |
| 3642 | |
| 3643 `left-margin' | |
| 3644 `right-margin' | |
| 3645 These are the faces that the left and right annotation margins are | |
| 3646 displayed in. | |
| 3647 | |
| 3648 `zmacs-region' | |
| 3649 This is the face that mouse selections are displayed in. | |
| 3650 | |
| 3651 `text-cursor' | |
| 3652 This is the face that the cursor is displayed in. | |
| 3653 | |
| 3654 `isearch' | |
| 3655 This is the face that the matched text being searched for is | |
| 3656 displayed in. | |
| 3657 | |
| 3658 `info-node' | |
| 3659 This is the face of info menu items. If unspecified, it is copied | |
| 3660 from `bold-italic'. | |
| 3661 | |
| 3662 `info-xref' | |
| 3663 This is the face of info cross-references. If unspecified, it is | |
| 3664 copied from `bold'. (Note that, when the mouse passes over a | |
| 3665 cross-reference, the cross-reference's face is determined from a | |
| 3666 combination of the `info-xref' and `highlight' faces.) | |
| 3667 | |
| 3668 Other packages might define their own faces; to see a list of all | |
| 3669 faces, use any of the interactive face-manipulation commands such as | |
| 3670 `set-face-font' and type `?' when you are prompted for the name of a | |
| 3671 face. | |
| 3672 | |
| 3673 If the `bold', `italic', and `bold-italic' faces are not specified | |
| 3674 in the resource database, then XEmacs attempts to derive them from the | |
| 3675 font of the default face. It can only succeed at this if you have | |
| 3676 specified the default font using the XLFD (X Logical Font Description) | |
| 3677 format, which looks like | |
| 3678 | |
| 3679 *-courier-medium-r-*-*-*-120-*-*-*-*-*-* | |
| 3680 | |
| 3681 If you use any of the other, less strict font name formats, some of | |
| 3682 which look like | |
| 3683 | |
| 3684 lucidasanstypewriter-12 | |
| 3685 fixed | |
| 3686 9x13 | |
| 3687 | |
| 3688 then XEmacs won't be able to guess the names of the bold and italic | |
| 3689 versions. All X fonts can be referred to via XLFD-style names, so you | |
| 3690 should use those forms. See the man pages for `X(1)', `xlsfonts(1)', | |
| 3691 and `xfontsel(1)'. | |
| 3692 | |
| 3693 | |
| 3694 **** Widgets | |
| 3695 ------------ | |
| 3696 | |
| 3697 There are several structural widgets between the terminal EmacsFrame | |
| 3698 widget and the top level ApplicationShell; the exact names and types of | |
| 3699 these widgets change from release to release (for example, they changed | |
| 3700 in 19.9, 19.10, 19.12, and 19.13) and are subject to further change in | |
| 3701 the future, so you should avoid mentioning them in your resource database. | |
| 3702 The above-mentioned syntaxes should be forward-compatible. As of 19.14, | |
| 3703 the exact widget hierarchy is as follows: | |
| 3704 | |
| 3705 INVOCATION-NAME "shell" "container" FRAME-NAME | |
| 3706 x-emacs-application-class "TopLevelEmacsShell" "EmacsManager" "EmacsFrame" | |
| 3707 | |
| 3708 (for normal frames) | |
| 3709 | |
| 3710 or | |
| 3711 | |
| 3712 INVOCATION-NAME "shell" "container" FRAME-NAME | |
| 3713 x-emacs-application-class "TransientEmacsShell" "EmacsManager" "EmacsFrame" | |
| 3714 | |
| 3715 (for popup/dialog-box frames) | |
| 3716 | |
| 3717 where INVOCATION-NAME is the terminal component of the name of the | |
| 3718 XEmacs executable (usually `xemacs'), and `x-emacs-application-class' | |
| 3719 is generally `Emacs'. | |
| 3720 | |
| 3721 | |
| 3722 **** Menubar Resources | |
| 3723 ---------------------- | |
| 3724 | |
| 3725 As the menubar is implemented as a widget which is not a part of | |
| 3726 XEmacs proper, it does not use the face mechanism for specifying fonts | |
| 3727 and colors: It uses whatever resources are appropriate to the type of | |
| 3728 widget which is used to implement it. | |
| 3729 | |
| 3730 If Emacs was compiled to use only the Motif-lookalike menu widgets, | |
| 3731 then one way to specify the font of the menubar would be | |
| 3732 | |
| 3733 Emacs*menubar*font: *-courier-medium-r-*-*-*-120-*-*-*-*-*-* | |
| 3734 | |
| 3735 If the Motif library is being used, then one would have to use | |
| 3736 | |
| 3737 Emacs*menubar*fontList: *-courier-medium-r-*-*-*-120-*-*-*-*-*-* | |
| 3738 | |
| 3739 because the Motif library uses the `fontList' resource name instead | |
| 3740 of `font', which has subtly different semantics. | |
| 3741 | |
| 3742 The same is true of the scrollbars: They accept whichever resources | |
| 3743 are appropriate for the toolkit in use. | |
| 3744 | |
| 3745 | |
| 3746 *** Source Code Highlighting | |
| 3747 ---------------------------- | |
| 3748 | |
| 3749 It's possible to have your buffers "decorated" with fonts or colors | |
| 3750 indicating syntactic structures (such as strings, comments, function names, | |
| 3751 "reserved words", etc.). In XEmacs, the preferred way to do this is with | |
| 3752 font-lock-mode; activate it by adding the following code to your .emacs file: | |
| 3753 | |
| 3754 (add-hook 'emacs-lisp-mode-hook 'turn-on-font-lock) | |
| 3755 (add-hook 'c-mode-hook 'turn-on-font-lock) | |
| 3756 (add-hook 'c++-mode-hook 'turn-on-font-lock) | |
| 3757 (add-hook 'dired-mode-hook 'turn-on-font-lock) | |
| 3758 ...etc... | |
| 3759 | |
| 3760 To customize it, see the descriptions of the function `font-lock-mode' and | |
| 3761 the variables `font-lock-keywords', `c-font-lock-keywords', etc. | |
| 3762 | |
| 3763 There exist several other source code highlighting packages, but font-lock | |
| 3764 does one thing that most others don't do: highlights as you type new text; | |
| 3765 and one thing that no others do: bases part of its decoration on the | |
| 3766 syntax table of the major mode. Font-lock has C-level support to do this | |
| 3767 efficiently, so it should also be significantly faster than the others. | |
| 3768 | |
| 3769 If there's something that another highlighting package does that you can't | |
| 3770 make font-lock do, let us know. We would prefer to consolidate all of the | |
| 3771 desired functionality into one package rather than ship several different | |
| 3772 packages which do essentially the same thing in different ways. | |
| 3773 | |
| 3774 | |
| 3775 ** Differences Between XEmacs and Emacs 18 | |
| 3776 ========================================== | |
| 3777 | |
| 3778 Auto-configure support has been added, so it should be fairly easy to compile | |
| 3779 XEmacs on different systems. If you have any problems or feedback about | |
| 3780 compiling on your system, please let us know. | |
| 3781 | |
| 3782 We have reimplemented the basic input model in a more general way; instead of | |
| 3783 X input being a special-case of the normal ASCII input stream, XEmacs has a | |
| 3784 concept of "input events", and ASCII characters are a subset of that. The | |
| 3785 events that XEmacs knows about are not X events, but are a generalization of | |
| 3786 them, so that XEmacs can eventually be ported to different window systems. | |
| 3787 | |
| 3788 We have reimplemented keymaps so that sequences of events can be stored into | |
| 3789 them instead of just ASCII codes; it is possible to, for example, bind | |
| 3790 different commands to each of the chords Control-h, Control-H, Backspace, | |
| 3791 Control-Backspace, and Super-Shift-Backspace. Key bindings, function key | |
| 3792 bindings, and mouse bindings live in the same keymaps. | |
| 3793 | |
| 3794 Input and display of all ISO-8859-1 characters is supported. | |
| 3795 | |
| 3796 You can have multiple X windows ("frames" in XEmacs terminology). | |
| 3797 | |
| 3798 XEmacs has objects called "extents" and "faces", which are roughly | |
| 3799 analogous to Epoch's "buttons," "zones," and "styles." An extent is a | |
| 3800 region of text (a start position and an end position) and a face is a | |
| 3801 collection of textual attributes like fonts and colors. Every extent | |
| 3802 is displayed in some "face", so changing the properties of a face | |
| 3803 immediately updates the display of all associated extents. Faces can | |
| 3804 be frame-local: you can have a region of text which displays with | |
| 3805 completely different attributes when its buffer is viewed from a | |
| 3806 different X window. | |
| 3807 | |
| 3808 The display attributes of faces may be specified either in lisp or through | |
| 3809 the X resource manager. | |
| 3810 | |
| 3811 Pixmaps of arbitrary size can be embedded in a buffer. | |
| 3812 | |
| 3813 Variable width fonts work. | |
| 3814 | |
| 3815 The height of a line is the height of the tallest font on that line, instead | |
| 3816 of all lines having the same height. | |
| 3817 | |
| 3818 XEmacs uses the MIT "Xt" toolkit instead of raw Xlib calls, which | |
| 3819 makes it be a more well-behaved X citizen (and also improves | |
| 3820 portability). A result of this is that it is possible to include | |
| 3821 other Xt "Widgets" in the XEmacs window. Also, XEmacs understands the | |
| 3822 standard Xt command-line arguments. | |
| 3823 | |
| 3824 XEmacs understands the X11 "Selection" mechanism; it's possible to define | |
| 3825 and customize selection converter functions and new selection types from | |
| 3826 Emacs Lisp, without having to recompile XEmacs. | |
| 3827 | |
| 3828 XEmacs provides support for ToolTalk on systems that have it. | |
| 3829 | |
| 3830 XEmacs supports the Zmacs/Lispm style of region highlighting, where the | |
| 3831 region between the point and mark is highlighted when in its "active" state. | |
| 3832 | |
| 3833 XEmacs has a menubar, whose contents are customizable from emacs-lisp. | |
| 3834 This menubar looks Motif-ish, but does not require Motif. If you already | |
| 3835 own Motif, however, you can configure XEmacs to use a *real* Motif menubar | |
| 3836 instead. | |
| 3837 | |
| 3838 XEmacs can ask questions using popup dialog boxes. Any command executed from | |
| 3839 a menu will ask yes/no questions with dialog boxes, while commands executed | |
| 3840 via the keyboard will use the minibuffer. | |
| 3841 | |
| 3842 XEmacs has vertical and horizontal scrollbars. | |
| 3843 | |
| 3844 The initial load-path is computed at run-time, instead of at compile-time. | |
| 3845 This means that if you move the XEmacs executable and associated directories | |
| 3846 to somewhere else, you don't have to recompile anything. | |
| 3847 | |
| 3848 You can specify what the title of the XEmacs windows and icons should be | |
| 3849 with the variables `frame-title-format' and `frame-icon-title-format', | |
| 3850 which have the same syntax as `mode-line-format'. | |
| 3851 | |
| 3852 XEmacs now supports floating-point numbers. | |
| 3853 | |
| 3854 XEmacs now knows about timers directly, instead of them being simulated by | |
| 3855 a subprocess. | |
| 3856 | |
| 3857 XEmacs understands truenames, and can be configured to notice when you are | |
| 3858 visiting two names of the same file. See the variables find-file-use-truenames | |
| 3859 and find-file-compare-truenames. | |
| 3860 | |
| 3861 If you're running on a machine with audio hardware, you can specify sound | |
| 3862 files for XEmacs to play instead of the default X beep. See the documentation | |
| 3863 of the function load-sound-file and the variable sound-alist. | |
| 3864 | |
| 3865 An XEmacs frame can be placed within an "external client widget" managed by | |
| 3866 another application. This allows an application to use an XEmacs frame as its | |
| 3867 text pane rather than the standard Text widget that is provided with Motif or | |
| 3868 Athena. XEmacs supports Motif applications, generic Xt (e.g. Athena) | |
| 3869 applications, and raw Xlib applications. | |
| 3870 | |
| 3871 Random changes to the emacs-lisp library: (some of this was not written by | |
| 3872 us, but is included because it's free software and we think it's good stuff) | |
| 3873 | |
| 3874 - there is a new optimizing byte-compiler | |
| 3875 - there is a new abbrev-based mail-alias mechanism | |
| 3876 - the -*- line can contain local-variable settings | |
| 3877 - there is a new TAGS package | |
| 3878 - there is a new VI-emulation mode (viper) | |
| 3879 - there is a new implementation of Dired | |
| 3880 - there is a new implementation of Isearch | |
| 3881 - the VM package for reading mail is provided | |
| 3882 - the W3 package for browsing the World Wide Web hypertext information | |
| 3883 system is provided | |
| 3884 - the Hyperbole package, a programmable information management and | |
| 3885 hypertext system | |
| 3886 - the OO-Browser package, a multi-language object-oriented browser | |
| 3887 | |
| 3888 There are many more specifics in the "Miscellaneous Changes" section, below. | |
| 3889 | |
| 3890 The online Emacs Manual and Emacs-Lisp Manual are now both relatively | |
| 3891 up-to-date. | |
| 3892 | |
| 3893 ** Major Differences Between 19.13 and 19.14 | |
| 3894 ============================================ | |
| 3895 | |
| 3896 XEmacs has a new address! The canonical ftp site is now | |
| 3897 ftp.xemacs.org:/pub/xemacs and the Web page is now at | |
| 3898 http://www.xemacs.org/. All mailing lists now have @xemacs.org | |
| 3899 addresses. For the time being the @cs.uiuc.edu addresses will | |
| 3900 continue to function. | |
| 3901 | |
| 3902 This is a major new release. Many features have been added, as well | |
| 3903 as many bugs fixed. The Motif menubar has still _NOT_ been fixed for | |
| 3904 19.14. You should use the Lucid menubar instead. | |
| 3905 | |
| 3906 | |
| 3907 | |
| 3908 Major user-visible changes: | |
| 3909 --------------------------- | |
| 3910 | |
| 3911 -- Color support in TTY mode is provided. You have to have a TTY capable | |
| 3912 of displaying them, such as color xterm or the console under Linux. | |
| 3913 If your terminal type supports colors (e.g. `xterm-color'), XEmacs | |
| 3914 will automatically notice this and start using color. | |
| 3915 | |
| 3916 -- blink-cursor-mode enables a blinking text cursor. There is a | |
| 3917 menubar option for this also. | |
| 3918 | |
| 3919 -- auto-show-mode is turned on by default; this means that XEmacs | |
| 3920 will automatically scroll a window horizontally as necessary to | |
| 3921 keep point in view. | |
| 3922 | |
| 3923 -- a file dialog box is provided and will be used whenever you | |
| 3924 are prompted for a filename as a result of a menubar selection. | |
| 3925 | |
| 3926 -- XEmacs can be compiled with built-in GIF, JPEG, and PNG support. | |
| 3927 The GIF libraries are supplied with XEmacs; for JPEG and PNG, | |
| 3928 you have to obtain the appropriate libraries (this is well- | |
| 3929 documented). This makes image display much easier and faster under | |
| 3930 W3 (the web browser) and TM (adds MIME support to VM and GNUS; | |
| 3931 not yet included with XEmacs but will be in 19.15). | |
| 3932 | |
| 3933 -- XEmacs provides a really nice mode (PSGML with "Wing improvements") | |
| 3934 for editing HTML and other SGML documents. It parses the document, | |
| 3935 and as a result it does proper indentation, can show you the context | |
| 3936 you're in, the allowed tags at a particular position, etc. | |
| 3937 | |
| 3938 -- XEmacs comes standard with modes for editing Java and VRML code, | |
| 3939 including font-lock support. | |
| 3940 | |
| 3941 -- GNUS 5.2 comes standard with XEmacs. | |
| 3942 | |
| 3943 -- You can now embed colors in the modeline, with different sections | |
| 3944 of the modeline responding appropriately to various mouse gestures: | |
| 3945 For example, clicking on the "read-only" indicator toggles the | |
| 3946 read-only status of a buffer, and clicking on the buffer name | |
| 3947 cycles to the next buffer. Pressing button3 on these areas brings | |
| 3948 up a popup menu of appropriate commands. | |
| 3949 | |
| 3950 -- There is a much nicer mode for completion lists and such. | |
| 3951 At the minibuffer prompt, if you hit page-up or Meta-V, the completion | |
| 3952 buffer will be displayed (if it wasn't already), you're moved into | |
| 3953 it, and can move around and select filenames using the arrow keys | |
| 3954 and the return key. Rather than a cursor, a filename is highlighted, | |
| 3955 and the arrow keys change which filename is highlighted. | |
| 3956 | |
| 3957 -- The edit-faces subsystem has also been much improved, in somewhat | |
| 3958 similar ways to the completion list improvements. | |
| 3959 | |
| 3960 -- Many improvements were made to the multi-device support. | |
| 3961 We now provide an auxiliary utility called "gnuattach" that | |
| 3962 lets you connect to an existing XEmacs process and display | |
| 3963 a TTY frame on the current TTY connection, and commands | |
| 3964 `make-frame-on-display' (with a corresponding menubar entry) | |
| 3965 and `make-frame-on-tty' for more easily creating frames on | |
| 3966 new TTY or X connections. | |
| 3967 | |
| 3968 -- We have incorporated nearly all of the functionality of GNU Emacs | |
| 3969 19.30 into XEmacs. This includes support for lazy-loaded | |
| 3970 byte code and documentation strings, improved paragraph filling, | |
| 3971 better support for margins within documents, v19 regular expression | |
| 3972 routines (including caching of compiled regexps), etc. | |
| 3973 | |
| 3974 -- In accordance with GNU Emacs 19.30, the following key binding | |
| 3975 changes have been made: | |
| 3976 | |
| 3977 C-x ESC -> C-x ESC ESC | |
| 3978 ESC ESC -> ESC : | |
| 3979 ESC ESC ESC is "abort anything" (keyboard-escape-quit). | |
| 3980 | |
| 3981 -- All major packages have been updated to their latest-released | |
| 3982 versions. | |
| 3983 | |
| 3984 -- XEmacs now gracefully handles a full colormap (such as typically | |
| 3985 results when running Netscape). The nearest available color | |
| 3986 is automatically substituted. | |
| 3987 | |
| 3988 -- Many bug fixes to the subprocess/PTY code, ps-print, menubar | |
| 3989 functions, `set-text-properties', DEC Alpha support, toolbar | |
| 3990 resizing (the "phantom VM toolbar" bug), and lots and lots | |
| 3991 of other things were made. | |
| 3992 | |
| 3993 -- The ncurses library (a replacement for curses, found especially | |
| 3994 under Linux) is supported, and will be automatically used | |
| 3995 if it can be found. | |
| 3996 | |
| 3997 -- You can now undo in the minibuffer. | |
| 3998 | |
| 3999 -- Surrogate minibuffers now work. These are also sometimes referred | |
| 4000 to as "global" minibuffers. | |
| 4001 | |
| 4002 -- font-lock has been merged with GNU Emacs 19.30, improved defaults | |
| 4003 have been added, and changes have been made to the way it is | |
| 4004 configured. | |
| 4005 | |
| 4006 -- Many, many modes have menubar entries for them. | |
| 4007 | |
| 4008 -- `recover-session' lets you recover whatever files can be recovered | |
| 4009 after your XEmacs process has died unexpectedly. | |
| 4010 | |
| 4011 -- C-h k followed by a toolbar button press correctly reports | |
| 4012 the binding of the toolbar button. | |
| 4013 | |
| 4014 -- `function-key-map', `key-translation-map', and `keyboard-translate-table' | |
| 4015 are now correctly implemented. | |
| 4016 | |
| 4017 -- `show-message-log' (and its menubar entry under Edit) have been | |
| 4018 removed; instead use `view-lossage' (and its menubar entry under | |
| 4019 Help). | |
| 4020 | |
| 4021 -- There is a standard menubar entry for specifying which browser | |
| 4022 (Netscape, W3, Mosaic, etc.) to use when dispatching URL's | |
| 4023 in mail, Usenet news, etc. | |
| 4024 | |
| 4025 -- Improved native sound support under Linux. | |
| 4026 | |
| 4027 -- Lots of other things we forgot to mention. | |
| 4028 | |
| 4029 | |
| 4030 | |
| 4031 Significant Lisp-level changes: | |
| 4032 ------------------------------- | |
| 4033 | |
| 4034 -- Many improvements to the E-Lisp documentation have been made; | |
| 4035 it should now be up-to-date and complete in nearly all cases. | |
| 4036 | |
| 4037 -- XEmacs has extensive documentation on its internals, for | |
| 4038 would-be C hackers. | |
| 4039 | |
| 4040 -- Common-Lisp support (the CL package) is now dumped standard | |
| 4041 into XEmacs. No more need for (require 'cl) or anything | |
| 4042 like that. | |
| 4043 | |
| 4044 -- Full support for extents and text properties over strings is | |
| 4045 provided. | |
| 4046 | |
| 4047 -- The extent properties `start-open', `end-open', `start-closed', | |
| 4048 and `end-closed' now work correctly w.r.t. text properties. | |
| 4049 | |
| 4050 -- The `face' property of extents and text properties can now | |
| 4051 be a list. | |
| 4052 | |
| 4053 -- The `mouse-face' property from GNU Emacs is now supported. | |
| 4054 It supersedes the `highlight' property. | |
| 4055 | |
| 4056 -- `enriched' and `facemenu' packages from GNU Emacs have been ported. | |
| 4057 | |
| 4058 -- New functions for easier creation of dialog boxes: | |
| 4059 `get-dialog-box-response', `message-box', and `message-or-box'. | |
| 4060 | |
| 4061 -- `function-min-args' and `function-max-args' allow you to determine | |
| 4062 the minimum and maximum allowed arguments for any type of | |
| 4063 function (i.e. subr, lambda expression, byte-compiled function, etc.). | |
| 4064 | |
| 4065 -- Some C-level support for doing E-Lisp profiling is provided. | |
| 4066 See `start-profiling', `stop-profiling', and | |
| 4067 `pretty-print-profiling-info'. | |
| 4068 | |
| 4069 -- `current-process-time' reports the user, system, and real times | |
| 4070 for the currently running XEmacs process. | |
| 4071 | |
| 4072 -- `next-window', `previous-window', `next-frame', `previous-frame', | |
| 4073 `other-window', `get-lru-window', etc. have an extra device | |
| 4074 argument that allows you to restrict which devices it includes | |
| 4075 (normally all devices). Some functions that incorrectly ignored | |
| 4076 frames on different devices (e.g. C-x 0) are fixed. | |
| 4077 | |
| 4078 -- new functions `run-hook-with-args-until-success', | |
| 4079 `run-hook-with-args-until-failure'. | |
| 4080 | |
| 4081 -- generalized facility for local vs. global hooks. See `make-local-hook', | |
| 4082 `add-hook'. | |
| 4083 | |
| 4084 -- New functions for querying the window tree: `frame-leftmost-window', | |
| 4085 `frame-rightmost-window', `window-first-hchild', `window-first-vchild', | |
| 4086 `window-next-child', `window-previous-child', and `window-parent'. | |
| 4087 | |
| 4088 -- Epoch support works. This gets you direct access to some X events | |
| 4089 and objects (e.g. properties and property-notify events). | |
| 4090 | |
| 4091 -- The multi-device support has been majorly revamped. There is now | |
| 4092 a new concept of "consoles" (devices grouped together under a | |
| 4093 common keyboard/mouse), console-local variables, and a generalized | |
| 4094 concept of device/console connection. | |
| 4095 | |
| 4096 -- `display-buffer' synched with GNU Emacs 19.30, giving you lots of | |
| 4097 wondrous cruft such as | |
| 4098 -- unsplittable frames | |
| 4099 -- pop-up-frames, pop-up-frame-function | |
| 4100 -- special-display-buffer-names, special-display-regexps, | |
| 4101 special-display-function | |
| 4102 -- same-window-buffer-names, same-window-regexps | |
| 4103 | |
| 4104 -- XEmacs has support for accessing DBM- and/or DB-format databases, | |
| 4105 provided that you have the appropriate libraries on your system. | |
| 4106 | |
| 4107 -- There is a new font style: "strikethru" fonts. | |
| 4108 | |
| 4109 -- New data type "weak list", which is a list with special | |
| 4110 garbage-collection properties, similar to weak hash tables. | |
| 4111 | |
| 4112 -- `set-face-parent' makes one face inherit all properties from another. | |
| 4113 | |
| 4114 -- The junky frame parameters mechanism has been revamped as | |
| 4115 frame properties, which a standard property-list interface. | |
| 4116 | |
| 4117 -- Lots and lots of functions for working with property lists have | |
| 4118 been added. | |
| 4119 | |
| 4120 -- New functions `push-window-configuration', `pop-window-configuration', | |
| 4121 `unpop-window-configuration' for maintain a stack of window | |
| 4122 configurations. | |
| 4123 | |
| 4124 -- Many fixups to the glyph code; icons and mouse pointers are now | |
| 4125 properly merged into the glyph mechanism. | |
| 4126 | |
| 4127 -- `set-specifier' works more sensibly, like `set-face-property'. | |
| 4128 | |
| 4129 -- Many new specifiers for individually controlling toolbar height/width | |
| 4130 and visibility and text cursor visibility. | |
| 4131 | |
| 4132 -- New face `text-cursor' controls the colors of the text cursor. | |
| 4133 | |
| 4134 -- Many new variables for turning on debug information about the | |
| 4135 inner workings of XEmacs. | |
| 4136 | |
| 4137 -- Hash tables can now compare their keys using `equal' or `eql' | |
| 4138 as well as `eq'. | |
| 4139 | |
| 4140 -- Other things too numerous to mention. | |
| 4141 | |
| 4142 | |
| 4143 | |
| 4144 Significant configuration/build changes: | |
| 4145 ---------------------------------------- | |
| 4146 | |
| 4147 -- You can disable TTY support, toolbar support, scrollbar support, | |
| 4148 menubar support, and/or dialog box support at configure time | |
| 4149 to save memory. | |
| 4150 | |
| 4151 -- New configure option `--extra-verbose' shows the diagnostic | |
| 4152 output from feature testing; this should help track down | |
| 4153 problems with incorrect feature detection. | |
| 4154 | |
| 4155 -- `dont-have-xmu' is now `with-xmu', with the reversed sense. | |
| 4156 (It defaults to `yes'.) | |
| 4157 | |
| 4158 -- `with-mocklisp' lets you add Mocklisp support if you really | |
| 4159 need this. | |
| 4160 | |
| 4161 -- `with-term' for adding TERM support for Linux users. | |
| 4162 | |
| 4163 | |
| 4164 | |
| 4165 ** Major Differences Between 19.12 and 19.13 | |
| 4166 ============================================ | |
| 4167 | |
| 4168 This is primarily a bug-fix release. Lots of bugs have been fixed. | |
| 4169 Hopefully only a few have been introduced. The most noteworthy bug | |
| 4170 fixes are: | |
| 4171 | |
| 4172 -- There should be no more problems connecting XEmacs to an X | |
| 4173 server over SLIP or other slow connections. | |
| 4174 -- Periodic crashes when using the Buffers menu should be gone. | |
| 4175 -- etags would sometimes erase the current buffer; it doesn't | |
| 4176 any more. | |
| 4177 -- XEmacs will correctly exit if the X server dies. | |
| 4178 -- uniconified frames are displayed properly under TVTWM. | |
| 4179 -- Breakage in `add-menu-item' / `add-menu-button' is fixed. | |
| 4180 | |
| 4181 The Motif menubar has _NOT_ been fixed for 19.13. You should use the | |
| 4182 Lucid menubar instead. | |
| 4183 | |
| 4184 Multi-device support should now be working properly. You can now open | |
| 4185 an X device after having started out on a TTY device. | |
| 4186 | |
| 4187 Background pixmaps now work. See `set-face-background-pixmap'. | |
| 4188 | |
| 4189 Echo area messages are now saved to a buffer, " *Message Log*". To | |
| 4190 see this buffer, use the command `show-message-log'. It is possible | |
| 4191 to filter the message which are actually included by modifying the | |
| 4192 variables `log-message-ignore-regexps' and `log-message-ignore-labels'. | |
| 4193 | |
| 4194 You can now control which warnings you want to see. See | |
| 4195 `display-warning-suppressed-classes' and friends. | |
| 4196 | |
| 4197 You can now set the default location of an "other window" from the | |
| 4198 Options menu. | |
| 4199 | |
| 4200 "Save Options" now saves the state of all faces. | |
| 4201 | |
| 4202 You can choose which file "Save Options" writes into; see | |
| 4203 `save-options-file'. | |
| 4204 | |
| 4205 XPM support is no longer required for the toolbar. | |
| 4206 | |
| 4207 The relocating allocator is now enabled by default whenever possible. | |
| 4208 This allows buffer memory to be returned to the system when no longer | |
| 4209 in use which helps keep XEmacs process size down. | |
| 4210 | |
| 4211 The ability to have captioned toolbars has been added. Currently only | |
| 4212 the default toolbar actually has a captioned version provided. A new | |
| 4213 specifier variable, `toolbar-buttons-captioned-p' controls whether the | |
| 4214 toolbar is captioned. | |
| 4215 | |
| 4216 A copy of the XEmacs FAQ is now included and is available through info. | |
| 4217 | |
| 4218 The on-line E-Lisp reference manual has been significantly updated. | |
| 4219 | |
| 4220 There is now audio support under Linux. | |
| 4221 | |
| 4222 Modifier keys can now be sticky. This is controlled by the variable | |
| 4223 `modifier-keys-are-sticky'. | |
| 4224 | |
| 4225 manual-entry should now work correctly under Irix with the penalty of | |
| 4226 a longer startup time the first time it is invoked. If you are having | |
| 4227 problems with this on another system try setting | |
| 4228 `Manual-use-subdirectory-list' to t. | |
| 4229 | |
| 4230 make-tty-device no longer automatically creates the first frame. | |
| 4231 | |
| 4232 Rectangular regions now work correctly. | |
| 4233 | |
| 4234 ediff no longer sets synchronize-minibuffers to t unless you first set | |
| 4235 ediff-synchronize-minibuffers | |
| 4236 | |
| 4237 keyboard-translate-table has been implemented. This means that the | |
| 4238 `enable-flow-control' command for dealing with TTY connections that | |
| 4239 filter out ^S and ^Q now works. | |
| 4240 | |
| 4241 You can now create frames that are initially unmapped and frames that | |
| 4242 are "transient for another frame", meaning that they behave more like | |
| 4243 dialog-box frames. | |
| 4244 | |
| 4245 Other E-Lisp changes: | |
| 4246 | |
| 4247 -- Specifier `menubar-visible-p' for controlling menubar visibility | |
| 4248 -- Local command hooks should be set using `local-pre-command-hook' | |
| 4249 and `local-post-command-hook' instead of making the global | |
| 4250 equivalents be buffer-local. | |
| 4251 -- `quit-char', `help-char', `meta-prefix-char' can be any key specifier | |
| 4252 instead of just an integer. | |
| 4253 -- new functions `add-async-timeout' and `disable-async-timeout'. | |
| 4254 These let you create asynchronous timeouts, which are like | |
| 4255 normal timeouts except that they're executed even during | |
| 4256 running Lisp code. Use this with care! | |
| 4257 -- `debug-on-error' and `stack-trace-on-error' now enter the debugger | |
| 4258 only when an *unhandled* error occurs. If you want the old | |
| 4259 behavior, use `debug-on-signal' and `stack-trace-on-signal'. | |
| 4260 -- \U, \L, \u, \l, \E recognized specially in `replace-match'. | |
| 4261 These are standard ex/perl commands for changing the case of | |
| 4262 replaced text. | |
| 4263 -- New function event-matches-key-specifier-p. This provides | |
| 4264 a clean way of comparing keypress events with key specifiers | |
| 4265 such as 65, (shift home), etc. without having to resort | |
| 4266 to ugly `character-to-event' / `event-to-character' hacks. | |
| 4267 -- New function `add-to-list' | |
| 4268 -- New Common-Lisp functions `some', `every', `notevery', `notany', | |
| 4269 `adjoin', `union', `intersection', `set-difference', | |
| 4270 `set-exclusive-or', `subsetp' | |
| 4271 -- `remove-face-property' provides a clean way of removing a | |
| 4272 face property. | |
| 4273 | |
| 4274 Many of the Emacs Lisp packages have been updated. Some of the new | |
| 4275 Emacs Lisp packages --- | |
| 4276 | |
| 4277 ada-mode: major mode for editing Ada source | |
| 4278 | |
| 4279 arc-mode: simple editing of archives | |
| 4280 | |
| 4281 auto-show-mode: automatically scrolls horizontally to keep point on-screen | |
| 4282 | |
| 4283 completion: dynamic word completion mode | |
| 4284 | |
| 4285 dabbrev: the dynamic abbrev package has been rewritten and is much | |
| 4286 more powerful -- e.g. it searches in other buffers as well | |
| 4287 as the current one | |
| 4288 | |
| 4289 easymenu: menu support package | |
| 4290 | |
| 4291 live-icon: makes frame icons represent the current frame contents | |
| 4292 | |
| 4293 mailcrypt 3.2: mail encryption with PGP; included but v2.4 is still | |
| 4294 the default | |
| 4295 | |
| 4296 two-column: for editing two-column text | |
| 4297 | |
| 4298 | |
| 4299 ** Major Differences Between 19.11 and 19.12 | |
| 4300 ============================================ | |
| 4301 | |
| 4302 This is a huge new release. Almost every aspect of XEmacs has been changed | |
| 4303 at least somewhat. The highlights are: | |
| 4304 | |
| 4305 -- TTY support (includes face support) | |
| 4306 -- new redisplay engine; should be faster, less buggy, and more powerful | |
| 4307 -- terminology change from "screen" to "frame" | |
| 4308 -- built-in toolbar | |
| 4309 -- toolbar support added to many packages | |
| 4310 -- multiple device support (still in beta; improvements to come in | |
| 4311 19.13) | |
| 4312 -- Purify used to ensure that there are no memory leaks or memory corruption | |
| 4313 problems | |
| 4314 -- horizontal and vertical scrollbars in all windows | |
| 4315 -- new Lucid (i.e. look-alike Motif) scrollbar widget | |
| 4316 -- stay-up menus in the Lucid (look-alike Motif) menubar widget | |
| 4317 -- 3-d modeline | |
| 4318 -- new extents engine; should be faster, less buggy, and more powerful | |
| 4319 -- much more powerful control over faces | |
| 4320 -- expanded menubar | |
| 4321 -- more work on synching with GNU Emacs 19.28 | |
| 4322 -- new packages: Hyperbole, OOBR (object browser), hm--html-menus, viper, | |
| 4323 lazy-lock.el, ksh-mode.el, rsz-minibuf.el | |
| 4324 -- package updates for all major packages | |
| 4325 -- dynodump package for Solaris: provides proper undumping and portable | |
| 4326 binaries across different OS versions and machine types | |
| 4327 -- Greatly expanded concept of "glyphs" (pixmaps etc. in a buffer) | |
| 4328 -- built-in support for displaying X-Faces, if the X-Face library is | |
| 4329 available | |
| 4330 -- built-in support for SOCKS if the SOCKS library is available | |
| 4331 -- graceful behavior when the colormap is full (e.g. Netscape ate | |
| 4332 all the colors) | |
| 4333 -- built-in MD5 (secure hashing function) support | |
| 4334 | |
| 4335 | |
| 4336 More specific information: | |
| 4337 | |
| 4338 *** TTY Support | |
| 4339 --------------- | |
| 4340 | |
| 4341 The long-awaited TTY support is now available. XEmacs will start up | |
| 4342 in TTY mode (using the tty you started XEmacs from) if the DISPLAY | |
| 4343 environment variable is not set or if you use the `-nw' option. | |
| 4344 | |
| 4345 Faces are available on TTY's. For a demonstration, try editing a C | |
| 4346 file and turning on font-lock-mode. | |
| 4347 | |
| 4348 You can also connect to additional TTY's using `make-tty-device', | |
| 4349 whether your first frame was a TTY or an X window. This ability is | |
| 4350 not yet completely finished. | |
| 4351 | |
| 4352 The full event-loop capabilities (processes, timeouts, etc.) are | |
| 4353 available on TTY's. | |
| 4354 | |
| 4355 | |
| 4356 | |
| 4357 *** New Redisplay Engine | |
| 4358 ------------------------ | |
| 4359 | |
| 4360 The redisplay engine has been rewritten to improve its efficiency and | |
| 4361 to increase its functionality. It should also be significantly more | |
| 4362 bug-free than the previous redisplay engine. | |
| 4363 | |
| 4364 A line that is not big enough to display at the bottom of the window | |
| 4365 will normally be clipped (so that it is partially visible) rather than | |
| 4366 not displayed at all. The variable `pixel-vertical-clip-threshold' | |
| 4367 can be used to control the minimum space that must be available for a | |
| 4368 line to be clipped rather than not displayed at all. | |
| 4369 | |
| 4370 Tabs are displayed in such a way that things line up fairly well even | |
| 4371 in the presence of variable-width fonts and/or lines with | |
| 4372 multiply-sized fonts. | |
| 4373 | |
| 4374 Display tables are implemented, through the specifier variable | |
| 4375 `current-display-table'. They can be buffer-local, window-local, | |
| 4376 frame-local, or device-local. See below for info about specifiers. | |
| 4377 | |
| 4378 | |
| 4379 | |
| 4380 *** Toolbar | |
| 4381 ----------- | |
| 4382 | |
| 4383 There is now built-in support for a toolbar. A sample toolbar is | |
| 4384 visible by default at the top of the frame. Four separate toolbars | |
| 4385 can be configured (at the top, bottom, left, and right of the frame). | |
| 4386 The toolbar specification is similar to the menubar specification. | |
| 4387 The up, down, and disabled glyphs of a toolbar button can be | |
| 4388 separately controlled. Explanatory text can be echoed in the echo | |
| 4389 area when the mouse passes over a toolbar button. The size, contents, | |
| 4390 and visibility of the various toolbars can be controlled on a | |
| 4391 per-buffer, per-window, per-frame, and per-device basis through the | |
| 4392 use of specifiers. See the chapter on toolbars in the Lisp Reference | |
| 4393 Manual (included with XEmacs) for more information. | |
| 4394 | |
| 4395 The toolbar color and shadow thicknesses are currently controlled only | |
| 4396 through `modify-frame-parameters' and through X resources. We are | |
| 4397 planning on making these controllable through specifiers as well. (Our | |
| 4398 hope is to make `modify-frame-parameters' obsolete, as it is a clunky | |
| 4399 and not very powerful mechanism.) | |
| 4400 | |
| 4401 Info, GNUS, VM, W3, and various other packages include custom toolbars | |
| 4402 with them. | |
| 4403 | |
| 4404 | |
| 4405 | |
| 4406 *** Menubar | |
| 4407 ----------- | |
| 4408 | |
| 4409 Stay-up menus are implemented in the look-alike Motif menubar. | |
| 4410 | |
| 4411 The default menubar has been expanded to include most commonly-used | |
| 4412 functions in XEmacs. | |
| 4413 | |
| 4414 The options menu has been greatly expanded to include many more | |
| 4415 options. | |
| 4416 | |
| 4417 The menubar specification format has been greatly expanded. Per-menu | |
| 4418 activation hooks can be specified through the :filter keyword (thus | |
| 4419 obsoleting `activate-menubar-hook'); this allows for fast response | |
| 4420 time when you have a large and complex menu. You can dynamically | |
| 4421 control whether menu items are present through the :included and | |
| 4422 :config keywords. (The latter keyword implements a simple menubar | |
| 4423 configuration scheme, in conjunction with the variable | |
| 4424 `menubar-configuration'.) Many different menu-item separators (single | |
| 4425 or double line; solid or dashed; flat, etched-in, or etched-out) are | |
| 4426 available. See the chapter on menus in the Lisp Reference Manual for | |
| 4427 more information about all of this. | |
| 4428 | |
| 4429 New functions `add-submenu' and `add-menu-button' are available. | |
| 4430 These supersede the older `add-menu' and `add-menu-item' functions, | |
| 4431 and provide a more powerful and consistent interface. | |
| 4432 | |
| 4433 New convenience functions for popping up the part or all of the | |
| 4434 menubar in a pop-up menu are available: `popup-menubar-menu' and | |
| 4435 `popup-buffer-menu'. | |
| 4436 | |
| 4437 Menus are now incrementally constructed greatly improving menubar | |
| 4438 response time. | |
| 4439 | |
| 4440 | |
| 4441 | |
| 4442 *** Scrollbars | |
| 4443 -------------- | |
| 4444 | |
| 4445 A look-alike Motif scrollbar is now included with XEmacs. No longer | |
| 4446 will you have to suffer with ugly Athena scrollbars. | |
| 4447 | |
| 4448 Windows can now have horizontal scrollbars. Normally they are visible | |
| 4449 when the window's buffer is set to truncate lines rather than wrap | |
| 4450 them (e.g. `(setq truncate-lines t)'). | |
| 4451 | |
| 4452 All windows, not only the right-most ones, can have vertical | |
| 4453 scrollbars. | |
| 4454 | |
| 4455 The functions to change a scrollbar's width have been superseded by | |
| 4456 the specifier variables `scrollbar-width' and `scrollbar-height'. | |
| 4457 This allows their values to be controlled on a buffer-local, | |
| 4458 window-local, frame-local, and device-local basis. See below. | |
| 4459 | |
| 4460 The scrollbars interact better with the event loop (for example, you | |
| 4461 can type `C-h k', do a scrollbar action, and see a description of this | |
| 4462 scrollbar action printed as if you had pressed a key sequence or | |
| 4463 selected a menu item). | |
| 4464 | |
| 4465 The scrollbar behavior can be reprogrammed, by advising the | |
| 4466 `scrollbar-*' functions. | |
| 4467 | |
| 4468 | |
| 4469 | |
| 4470 *** Key Bindings | |
| 4471 ---------------- | |
| 4472 | |
| 4473 The oft-used function `goto-line' now has its own binding: M-g. | |
| 4474 | |
| 4475 New bindings are available for scrolling the "other" window: M-next, | |
| 4476 M-prior, M-home, M-end. (On many keyboards, `next' and `prior' | |
| 4477 labelled `PgUp' and `PgDn'.) | |
| 4478 | |
| 4479 You can reactivate a deactivated Zmacs region, without having any | |
| 4480 other effects, with the binding M-C-z. | |
| 4481 | |
| 4482 The bindings `M-u', `M-l', and `M-c' now work on the region (if a | |
| 4483 region is active) or work on a word, as before. | |
| 4484 | |
| 4485 Shift-Control-G forces a "critical quit", which drops immediately into | |
| 4486 the debugger; see below. | |
| 4487 | |
| 4488 | |
| 4489 | |
| 4490 *** Modeline | |
| 4491 ------------ | |
| 4492 | |
| 4493 The modeline can now have a 3-d look; this is enabled by default. The | |
| 4494 specifier variable `modeline-shadow-thickness' controls the size. | |
| 4495 | |
| 4496 The modeline can now be turned off on a per-buffer, per-window, | |
| 4497 per-frame, or per-device basis. The specifier variable | |
| 4498 `has-modeline-p' controls whether the modeline is visible. See below | |
| 4499 for details about the vastly powerful specifier mechanism. | |
| 4500 | |
| 4501 The modeline functions and variables have been renamed to be | |
| 4502 `*-modeline-*' rather than `*-mode-line-*'. Aliases are provided for | |
| 4503 all the old names. | |
| 4504 | |
| 4505 Variable width fonts now work correctly when used in the modeline. | |
| 4506 | |
| 4507 | |
| 4508 | |
| 4509 *** Minibuffer, Echo Area | |
| 4510 ------------------------- | |
| 4511 | |
| 4512 The minibuffer is no longer constrained to be one line high. The | |
| 4513 package rsz-minibuf.el is included to automatically resize the | |
| 4514 minibuffer when its contents are too big; enable this with | |
| 4515 `resize-minibuffer-mode'. | |
| 4516 | |
| 4517 The echo area is now a true buffer, called " *Echo Area*". This | |
| 4518 allows you to customize the echo area behavior through | |
| 4519 before-change-functions and after-change-functions. | |
| 4520 | |
| 4521 | |
| 4522 | |
| 4523 *** Specifiers | |
| 4524 -------------- | |
| 4525 | |
| 4526 XEmacs has a new concept called "specifiers", used to configure most | |
| 4527 display options (toolbar size and contents, scrollbar size, face | |
| 4528 properties, modeline visibility and shadow-thickness, glyphs, display | |
| 4529 tables, etc.). We are planning on converting all display | |
| 4530 characteristics to use specifiers, and obsoleting the clunky functions | |
| 4531 `frame-parameters' and `modify-frame-parameters'. Specifically: | |
| 4532 | |
| 4533 -- You can specify values (called "instantiators") for particular | |
| 4534 "locales" (i.e. buffers, windows, frames, devices, or a global value). | |
| 4535 When determining what the actual value (or "instance") of a specifier | |
| 4536 is, the specifications that are provided are searched from most | |
| 4537 specific (i.e. buffer-local) to most general (i.e. global), looking | |
| 4538 for a matching one. | |
| 4539 | |
| 4540 -- You can specify multiple instantiators for a particular locale. | |
| 4541 For example, when specifying what the foreground color of a face | |
| 4542 is in a particular buffer, you could specify two instantiators: | |
| 4543 "dark sea green" and "green". The color would then be dark sea | |
| 4544 green on devices that recognize that color, and green on other | |
| 4545 devices. You have effectively provided a fallback value to make | |
| 4546 sure you get reasonable behavior on all devices. | |
| 4547 | |
| 4548 -- You can add one or more tags to an instantiator, where a tag | |
| 4549 is a symbol that has been previously registered with XEmacs. | |
| 4550 This allows you to identify your instantiators for later | |
| 4551 removal in a way that won't interfere with other applications | |
| 4552 using the same specifier. Furthermore, particular tags can | |
| 4553 be restricted to match only particular sorts of devices. | |
| 4554 Any tagged instantiator will be ignored if the device over which | |
| 4555 it is being instanced does not match any of its tags. This | |
| 4556 allows you, for example, to restrict an instantiator to a | |
| 4557 particular device type (X or TTY) and/or class (color, grayscale, | |
| 4558 or mono). (You might want to specify, for example, that a | |
| 4559 particular face is displayed in green on color devices and is | |
| 4560 underlined on mono devices.) | |
| 4561 | |
| 4562 -- A full API is provided for manipulating specifiers, and full | |
| 4563 documentation is provided in the Lisp Reference Manual. | |
| 4564 | |
| 4565 | |
| 4566 | |
| 4567 *** Basic Lisp Stuff | |
| 4568 -------------------- | |
| 4569 | |
| 4570 Common-Lisp backquote syntax is recognized. For example, the old | |
| 4571 expression | |
| 4572 | |
| 4573 (` (a b (, c))) | |
| 4574 | |
| 4575 can now be written | |
| 4576 | |
| 4577 `(a b ,c) | |
| 4578 | |
| 4579 The old backquote syntax is still accepted. | |
| 4580 | |
| 4581 The new function `type-of' returns a symbol describing the type of a | |
| 4582 Lisp object (`integer', `string', `symbol', etc.) | |
| 4583 | |
| 4584 Symbols beginning with a colon (called "keywords") are treated | |
| 4585 specially in that they are automatically made self-evaluating when | |
| 4586 they are interned into `obarray'. The new function `keywordp' returns | |
| 4587 whether a symbol begins with a colon. | |
| 4588 | |
| 4589 `get', `put', and `remprop' have been generalized to allow you to set | |
| 4590 and retrieve properties on many different kinds of objects: symbols, | |
| 4591 strings, faces, glyphs, and extents (for extents, however, this is not | |
| 442 | 4592 yet implemented). They are joined by a new function `object-plist' |
| 428 | 4593 that returns all of the properties that have been set on an object. |
| 4594 | |
| 4595 New functions `plists-eq' and `plists-equal' are provided for | |
| 4596 comparing property lists (a property list is an alternating list | |
| 4597 of keys and values). | |
| 4598 | |
| 4599 The Common-Lisp functions `caar', `cadr', `cdar', `cddr', `caaar', etc. | |
| 4600 (up to four a's and/or d's), `first', `second', `third', etc. (up to | |
| 4601 `tenth'), `last', `rest', and `endp' have been added, for more | |
| 4602 convenient manipulation of lists. | |
| 4603 | |
| 4604 New function `mapvector' maps over a sequence and returns a vector | |
| 4605 of the results, analogous to `mapcar'. | |
| 4606 | |
| 4607 New functions `rassoc', `remassoc', `remassq', `remrassoc', and | |
| 4608 `remrassq' are provided for working with alists. | |
| 4609 | |
| 4610 New functions `defvaralias', `variable-alias' and `indirect-variable' | |
| 4611 are provided for creating variable aliases. | |
| 4612 | |
| 4613 Strings have a modified-tick that is bumped every time a string | |
| 4614 is modified in-place with `aset' or `fillarray'. This is retrieved | |
| 4615 with the new function `string-modified-tick'. | |
| 4616 | |
| 4617 New macro `push' destructively adds an element to the beginning of a | |
| 4618 list. New macro `pop' destructively removes and returns the first | |
| 4619 element of a list. | |
| 4620 | |
| 4621 | |
| 4622 | |
| 4623 *** Buffers | |
| 4624 ----------- | |
| 4625 | |
| 4626 Most functions that operate on buffer text now take an optional BUFFER | |
| 4627 argument, specifying which buffer they operate on. (Previously, they | |
| 4628 always operated on the current buffer.) | |
| 4629 | |
| 4630 The new function `transpose-regions' is provided, ported from GNU | |
| 4631 Emacs. | |
| 4632 | |
| 4633 The new function `save-current-buffer' works like `save-excursion' | |
| 4634 but only saves the current buffer, not the location of point in | |
| 4635 that buffer. | |
| 4636 | |
| 4637 | |
| 4638 | |
| 4639 *** Devices | |
| 4640 ----------- | |
| 4641 | |
| 4642 XEmacs has a new concept of "device", which is represents a particular | |
| 4643 X display or TTY connection. `make-frame' has a new, optional device | |
| 4644 parameter that allows you to specify which device the frame is to be | |
| 4645 created on. | |
| 4646 | |
| 4647 Multiple simultaneous TTY and/or X connections may be made. The | |
| 4648 specifier mechanism provides reasonable behavior of glyphs, faces, | |
| 4649 etc. over heterogeneous device types and over devices whose individual | |
| 4650 capabilities may vary. | |
| 4651 | |
| 4652 There is also a device type called "stream" that represents a STDIO | |
| 4653 device that has no redisplay or cursor-motion capabilities, such as | |
| 4654 the "glass terminal" that XEmacs uses when it is run noninteractively. | |
| 4655 There is not all that much you can do with stream devices currently; | |
| 4656 please let us know if there are good uses you can think of for this | |
| 4657 capability. (For example, log files?) | |
| 4658 | |
| 4659 A new device API is provided. Functions are provided such as | |
| 4660 `device-name' (the name of the device, which generally is based on the | |
| 4661 X display or TTY file name), `device-type' (X, TTY, or stream), | |
| 4662 `device-class' (color, grayscale, or mono), etc. See the Lisp | |
| 4663 Reference Manual. | |
| 4664 | |
| 4665 Many functions have been extended to contain an additional, optional | |
| 4666 device argument, where such an extension makes sense. In general, if | |
| 4667 the argument is omitted, it is equivalent to specifying | |
| 4668 `(selected-device)'. | |
| 4669 | |
| 4670 Many previous functions and variables are obsoleted in favor of the | |
| 4671 device API. For example, `window-system' is obsoleted by | |
| 4672 `device-type', and `x-color-display-p' and friends are obsoleted by | |
| 4673 `device-class'. | |
| 4674 | |
| 4675 *** NOTE **: The obsolete variable `window-system' is going | |
| 4676 to be deleted soon, probably in 19.14. Please correct all | |
| 4677 your code to use `device-type'. | |
| 4678 | |
| 4679 *** INCOMPATIBLE CHANGE **: The function `x-display-visual-class' | |
| 4680 returns different values from previous versions of XEmacs. | |
| 4681 | |
| 4682 | |
| 4683 | |
| 4684 *** Errors, Warnings, C-g | |
| 4685 ------------------------- | |
| 4686 | |
| 4687 There is a new warnings system implemented. Many warnings that were | |
| 4688 formerly displayed in various ad-hoc ways (e.g. warnings about screwy | |
| 4689 modifier mappings, messages about failures handling the mouse cursor | |
| 4690 and errors in a gc-hook) have been regularized through this system. | |
| 4691 The new function `warn' displays a warning before the next redisplay | |
| 4692 (the actually display of the warning messages is accomplished through | |
| 4693 `display-warning-buffer'). Both `warn' and `display-warning-buffer' | |
| 4694 are Lisp functions (the C code calls out to them as necessary), and | |
| 4695 thus you can customize the warning system. | |
| 4696 | |
| 4697 Under an X display, you can press Shift-Control-G to force a "critical | |
| 4698 quit". This will immediately display a backtrace and pop you into the | |
| 4699 debugger, regardless of the settings of `inhibit-quit' and | |
| 4700 `debug-on-quit'. | |
| 4701 | |
| 4702 C-g now works properly even on systems that don't implement SIGIO or | |
| 4703 for which SIGIO is broken (e.g. IRIX 5.3 and older versions of Linux). | |
| 4704 In addition, the SIGIO support has been fixed for many systems on | |
| 4705 which it didn't always work properly before (e.g. HPUX and Solaris). | |
| 4706 | |
| 4707 | |
| 4708 | |
| 4709 *** Events | |
| 4710 ---------- | |
| 4711 | |
| 4712 *** INCOMPATIBLE CHANGE **: Many event functions have been changed to | |
| 4713 accept and return windows instead of frames. | |
| 4714 | |
| 4715 New function: `event-live-p', specifying whether `deallocate-event' | |
| 4716 has been called on an event. | |
| 4717 | |
| 4718 The "menu event" type has been renamed to "misc-user event", and | |
| 4719 encompasses scrollbar events as well as menu events. We are planning | |
| 4720 on making it also encompass toolbar events in a future release. | |
| 4721 | |
| 4722 New functions are provided for determining whether an particular | |
| 4723 sections of a frame: `event-over-border-p', `event-over-glyph-p', | |
| 4724 `event-over-modeline-p', `event-over-text-area-p', and | |
| 4725 `event-over-toolbar-p'. The old, kludgey methods of checking the | |
| 4726 window-height, the internal-border-width, etc. are unreliable and | |
| 4727 should not be used. | |
| 4728 | |
| 4729 New functions `event-window-x-pixel' and `event-window-y-pixel' are | |
| 4730 provided for determining where in a particular window an event | |
| 4731 happened. | |
| 4732 | |
| 4733 New functions `event-glyph-x-pixel' and `event-glyph-y-pixel' are | |
| 4734 provided for determining where in a particular glyph an event | |
| 4735 happened. | |
| 4736 | |
| 4737 New function `event-closest-point', which returns the closest buffer | |
| 4738 position to the event even if the event did not occur over any text. | |
| 4739 | |
| 4740 New variable `unread-command-events', superseding the older | |
| 4741 `unread-command-event'. | |
| 4742 | |
| 4743 Many event-loop bugs have been fixed. | |
| 4744 | |
| 4745 | |
| 4746 | |
| 4747 *** Extents | |
| 4748 ----------- | |
| 4749 | |
| 4750 The extent code has been largely rewritten. It should be faster and | |
| 4751 more reliable. | |
| 4752 | |
| 4753 The text-property implementation has been greatly improved. | |
| 4754 | |
| 4755 Some new extent primitives are provided to return the position of the | |
| 4756 next or previous property change in a buffer. | |
| 4757 | |
| 4758 Extents can now have a parent specified; then all of its properties | |
| 4759 (except for the buffer it's in and its position in that buffer) come | |
| 4760 from that extent. Hierarchies of such extents can be created. | |
| 4761 | |
| 4762 Extents now have a `detachable' property that controls what happens | |
| 4763 (they either get detached or shrink down to zero-length) when their | |
| 4764 text is deleted. Previously, such extents would always be detached. | |
| 4765 | |
| 4766 The `invisible' property on extents now works. | |
| 4767 | |
| 4768 `map-extents' has three additional parameters that provide more | |
| 4769 control over which extents are mapped. | |
| 4770 | |
| 4771 `map-extents' deals better with changes made to extents in the | |
| 4772 buffer being mapped over. | |
| 4773 | |
| 4774 A new function `mapcar-extents' (an alternative to `map-extents') has | |
| 4775 been provided and should be easier to use than `map-extents'. | |
| 4776 | |
| 4777 | |
| 4778 | |
| 4779 *** Faces | |
| 4780 --------- | |
| 4781 | |
| 4782 Faces can now be buffer-local, window-local, and device-local as well | |
| 4783 as frame-local, and can be further restricted to a particular device | |
| 4784 type or class. The way in which faces can be controlled is now based | |
| 4785 on the general and powerful specifier mechanism; see above. | |
| 4786 | |
| 4787 The new function `set-face-property' generalizes `set-face-font', | |
| 4788 `set-face-foreground', etc. and takes many new optional arguments, in | |
| 4789 accordance with the new specifier mechanism. | |
| 4790 | |
| 4791 The new functions `face-property' and `face-property-instance' | |
| 4792 generalize `face-font', `face-foreground', etc. and take many new | |
| 4793 optional arguments, in accordance with the new specifier mechanism. | |
| 4794 (`face-property' returns the value, if any, that was specified for a | |
| 4795 particular locale, and `face-property-instance' returns the actual | |
| 4796 value that will be used for display. See the section on specifiers.) | |
| 4797 | |
| 4798 The functions `face-font', `face-foreground', `face-background', | |
| 4799 `set-face-font', `set-face-foreground', `set-face-background', | |
| 4800 etc. are now convenience functions, trivially implemented using | |
| 4801 `face-property' and `set-face-property' and take new optioanl | |
| 4802 arguments in accordance with those functions. New convenience | |
| 4803 functions `face-font-instance', `face-foreground-instance', | |
| 4804 `face-background-instance', etc. are provided and are trivially | |
| 4805 implemented using `face-property-instance'. | |
| 4806 | |
| 4807 Inheritance of face properties can now be specified. Each individual | |
| 4808 face property can inherit differently from other properties, or not | |
| 4809 inherit at all. | |
| 4810 | |
| 4811 You can set user-defined properties on faces using | |
| 4812 `set-face-property'. | |
| 4813 | |
| 4814 You can create "temporary" faces, which are faces that disappear | |
| 4815 when they are no longer in use. This is as opposed to normal | |
| 4816 faces, which stay around forever. | |
| 4817 | |
| 4818 The function `make-face' takes a new optional argument specifying | |
| 4819 whether a face should be permanent or temporary, and returns the | |
| 4820 actual face object rather than the face symbol, as in previous | |
| 4821 versions of XEmacs. | |
| 4822 | |
| 4823 The function `face-list' takes a new optional argument specifying | |
| 4824 whether permanent, temporary, or both kinds of faces should be | |
| 4825 returned. | |
| 4826 | |
| 4827 Faces have new TTY-specific properties: `highlight', `reverse', | |
| 4828 `alternate', `blinking', and `dim'. | |
| 4829 | |
| 4830 Redisplay is smarter about dealing with face changes: changes to a | |
| 4831 particular face no longer cause all frames to be cleared and | |
| 4832 redisplayed. | |
| 4833 | |
| 4834 The Edit-Faces package is provided for interactively changing faces. | |
| 4835 A menu item on the options menu is provided for this. | |
| 4836 | |
| 4837 New functions are provided for retrieving the ascent, descent, height, | |
| 4838 and width of a character in a particular face. | |
| 4839 | |
| 4840 | |
| 4841 | |
| 4842 *** Fonts, Colors | |
| 4843 ----------------- | |
| 4844 | |
| 4845 *** INCOMPATIBLE CHANGE **: The old "font" and "pixel" objects are gone. | |
| 4846 In place are new objects "font specifier", "font instance", "color | |
| 4847 specifier", and "color instance". Functions `font-name', `pixel-name' | |
| 4848 (an obsolete alias for `color-name'), etc. are now convenience | |
| 4849 functions for working with font and color specifiers. Old code that | |
| 4850 is not too sophisticated about working with font and pixel objects may | |
| 4851 still work, though. (For example, the idiom `(font-name (face-font | |
| 4852 'default))' still works.) | |
| 4853 | |
| 4854 You can now extract the RGB components of a color-instance object | |
| 4855 (similar to the old pixel object) with the function | |
| 4856 `color-instance-rgb-components'. There is also a convenience function | |
| 4857 `color-rgb-components' for working with color specifiers. | |
| 4858 | |
| 4859 If there are no more colors available in the colormap, the nearest | |
| 4860 existing color will be used when allocating a new color. | |
| 4861 | |
| 4862 | |
| 4863 | |
| 4864 *** Frames | |
| 4865 ---------- | |
| 4866 | |
| 4867 What used to be called "screens" are now called "frames", for clarity | |
| 4868 and consistency with GNU Emacs. Aliases are provided for all the old | |
| 4869 screen functions and variables, to avoid introducing a huge E-Lisp | |
| 4870 incompatibility. | |
| 4871 | |
| 4872 The frame code has been merged with GNU Emacs 19.28, providing | |
| 4873 improved functionality for many functions. | |
| 4874 | |
| 4875 | |
| 4876 | |
| 4877 *** Glyphs, Images, and Pixmaps | |
| 4878 ------------------------------- | |
| 4879 | |
| 4880 Glyphs (used in various places, i.e. as begin-glyphs and end-glyphs | |
| 4881 attached to extents and appearing in a buffer or in marginal | |
| 4882 annotations; as the truncator and continuor glyphs marking line wrap | |
| 4883 or truncation; as an overlay at the beginning of a line; as the | |
| 4884 displayable element in a toolbar button; etc.) can now be | |
| 4885 buffer-local, window-local, frame-local, and device-local, and can be | |
| 4886 further restricted to a particular device type or class. The way in | |
| 4887 which faces can be controlled is now based on the general and powerful | |
| 4888 specifier mechanism; see above. | |
| 4889 | |
| 4890 *** INCOMPATIBLE CHANGE **: The glyph and pixmap API has been completely | |
| 4891 overhauled. A new Lisp object "glyph" is provided and should be used | |
| 4892 where the old "pixmap" object would have been used. The pixmap object | |
| 4893 exists no longer. There are also new Lisp objects "image specifier" | |
| 4894 and "image instance" (an image-instance is the closest equivalent to | |
| 4895 what a pixmap object was). More work on glyphs and images is slated | |
| 4896 for 19.13. The glyph and image docs in the Lisp Reference Manual are | |
| 4897 incomplete and will be finished in 19.13. | |
| 4898 | |
| 4899 The new function `set-glyph-property' allows setting of all the | |
| 4900 glyph properties (`baseline', `contrib-p', etc.). Convenience | |
| 4901 functions for particular properties are also provided, just like | |
| 4902 for faces. | |
| 4903 | |
| 4904 You can set user-defined properties on glyphs using the new function | |
| 4905 `set-glyph-property'. | |
| 4906 | |
| 4907 When displaying pixmaps, existing, closest-matching colors will be | |
| 4908 used if the colormap is full. | |
| 4909 | |
| 4910 If the compface library is compiled into XEmacs, there is built-in | |
| 4911 support for displaying X-Face bitmaps. (These are typically small | |
| 4912 pictures of people's faces, included in a mail message through the | |
| 4913 X-Face: header.) VM and highlight-headers will automatically use the | |
| 4914 built-in X-Face support if it is available. | |
| 4915 | |
| 4916 Annotations in the right margin (as well as the left margin) are now | |
| 4917 implemented. The left and right margin width functions have been | |
| 4918 superseded by the specifier variables `left-margin-width' and | |
| 4919 `right-margin-width', allowing much more flexible control through the | |
| 4920 specifier mechanism. | |
| 4921 | |
| 4922 *** INCOMPATIBLE CHANGE **: The variable `use-left-overflow', | |
| 4923 for controlling annotations in the left margin, is now a specifier | |
| 4924 variable instead of a buffer-local variable. (There is also a new | |
| 4925 variable `use-right-overflow', that is complementary.) | |
| 4926 | |
| 4927 | |
| 4928 | |
| 4929 *** Hashing | |
| 4930 ----------- | |
| 4931 | |
| 4932 Two new types of weak hashtables can be created: key-weak and | |
| 4933 value-weak. In a key-weak hashtable, an entry remains around | |
| 4934 if its key is referenced elsewhere, regardless of whether this | |
| 4935 is also the case for the value. Value-weak hashtables are | |
| 4936 complementary. (This is as opposed to the traditional weak | |
| 4937 hashtables, where an entry remains around only if both the | |
| 4938 key and value are referenced elsewhere.) New functions | |
| 4939 `make-key-weak-hashtable' and `make-value-weak-hashtable' | |
| 4940 are provided for creating these hashtables. | |
| 4941 | |
| 4942 The new function `md5' is provided for performing an MD5 | |
| 4943 hash of an object. MD5 is a secure message digest algorithm | |
| 4944 developed by RSA, inc. | |
| 4945 | |
| 4946 | |
| 4947 | |
| 4948 *** Keymaps | |
| 4949 ----------- | |
| 4950 | |
| 4951 The GNU Emacs concept of `function-key-map' is now partially | |
| 4952 implemented. This allows conversion of function-key escape sequences | |
| 4953 such as `ESC [ 1 1 ~' into an equivalent human-readable keysym such as | |
| 4954 `F1'. This work will be completed in 19.14. The function-key map is | |
| 4955 device-local and controllable through the functions | |
| 4956 `device-function-key-map' and `set-device-function-key-map'. | |
| 4957 | |
| 4958 `where-is-internal' now correctly searches minor-mode keymaps, | |
| 4959 extent-local keymaps, etc. As a side effect of this, menu items will | |
| 4960 now correctly show the keyboard equivalent for commands that are | |
| 4961 available through a minor-mode keymap, extent-local keymap, etc. | |
| 4962 | |
| 4963 *** INCOMPATIBLE CHANGE **: The modifier key "Symbol" has | |
| 4964 been renamed to "Alt", for compatibility with the rest of the world. | |
| 4965 Keep in mind that on many keyboards, the key labelled "Alt" actually | |
| 4966 generates the "Meta" modifier. (On Sun keyboards, however, the key | |
| 4967 labelled "Alt" does indeed generate the "Alt" modifier, and the key | |
| 4968 labelled with a diamond generates the "Meta" modifier.) | |
| 4969 | |
| 4970 | |
| 4971 | |
| 4972 *** Mouse, Active Region | |
| 4973 ------------------------ | |
| 4974 | |
| 4975 The mouse internals in mouse.el have been rewritten. Hooks have been | |
| 4976 provided for easier customization of mouse behavior. For example, you | |
| 4977 can now easily specify an action to be invoked on single-click | |
| 4978 (i.e. down-up without appreciable motion), double-click, drag-up, etc. | |
| 4979 | |
| 4980 Some code from GNU Emacs has been ported over, generalizing some of | |
| 4981 the X-specific mouse stuff. | |
| 4982 | |
| 4983 *** INCOMPATIBLE CHANGE **: The function `set-mouse-position' accepts | |
| 4984 a window instead of a frame. | |
| 4985 | |
| 4986 New function `mouse-position' that obsoletes and is more powerful than | |
| 4987 `read-mouse-position'. | |
| 4988 | |
| 4989 New functions `mouse-pixel-positon' and `set-mouse-pixel-position' for | |
| 4990 working with pixels instead of characters. | |
| 4991 | |
| 4992 The active (Zmacs) region is now highlighted using the `zmacs-region-face' | |
| 4993 instead of the `primary-selection-face'; this generalizes what used | |
| 4994 to be X-specific. | |
| 4995 | |
| 4996 New functions `region-active-p', `region-exists-p', and `activate-region' | |
| 4997 provide a uniform API for dealing with the region irrespective of | |
| 4998 whether the variable `zmacs-regions' is set. | |
| 4999 | |
| 5000 XEmacs is now a better X citizen with respect to the primary selection: | |
| 5001 it does not stomp on the primary selection quite so much. This makes | |
| 5002 things more manageable if you set `zmacs-regions' to nil. | |
| 5003 | |
| 5004 | |
| 5005 | |
| 5006 *** Processes | |
| 5007 ------------- | |
| 5008 | |
| 5009 Various process race conditions and bugs have been fixed. Problems | |
| 5010 with process termination not getting noticed until much later (if at | |
| 5011 all) should be gone now, as well as problems with zombie processes | |
| 5012 under some systems. | |
| 5013 | |
| 5014 SOCKS support is now included. SOCKS is a package that allows hosts | |
| 5015 behind a firewall to gain full access to the Internet without | |
| 5016 requiring direct IP reachability. | |
| 5017 | |
| 5018 | |
| 5019 | |
| 5020 *** Windows | |
| 5021 ----------- | |
| 5022 | |
| 5023 Windows 95 is still not out yet. | |
| 5024 | |
| 5025 *** INCOMPATIBLE CHANGE **: The functions `locate-window-from-coordinates' | |
| 5026 and `window-edges' have been eliminated. It no longer makes sense to | |
| 5027 work with windows in terms of character positions, because windows can | |
| 5028 (and often do) have many differently-sized fonts in them, because the | |
| 5029 3-D modeline is not exactly one line high, etc. | |
| 5030 | |
| 5031 The new functions `window-pixel-edges', `window-highest-p', | |
| 5032 `window-lowest-p', `frame-highest-window', and `frame-lowest-window' | |
| 5033 are provided as substitutes for the above-mentioned, deleted | |
| 5034 functions. | |
| 5035 | |
| 5036 The function `window-end' now takes an optional GUARANTEE argument | |
| 5037 that will ensure that the value is actually correct as of the next | |
| 5038 redisplay. | |
| 5039 | |
| 5040 The window code has been merged with GNU Emacs 19.28, providing | |
| 5041 improved functionality for many functions. | |
| 5042 | |
| 5043 | |
| 5044 | |
| 5045 *** System-Specific Information | |
| 5046 ------------------------------- | |
| 5047 | |
| 5048 Georg Nikodym's dynodump package is provided, for proper unexec()ing | |
| 5049 on Solaris systems. Executables built on Solaris 2.3 can now run on | |
| 5050 Solaris 2.4 without crashing; similarly with executables built on one | |
| 5051 type of Sun machine and run on another. | |
| 5052 | |
| 5053 AIX 4.x is supported. | |
| 5054 | |
| 5055 The NeXTstep operating system is supported in TTY mode (this is still | |
| 5056 in beta). There are plans to port XEmacs to the NeXTstep window | |
| 5057 system, but it may be awhile before this is complete. | |
| 5058 | |
| 5059 Problems with the `round' function causing arithmetic errors on HPUX 9 | |
| 5060 have been fixed. | |
| 5061 | |
| 5062 You can now build XEmacs as an ELF executable on Linux systems that | |
| 5063 support ELF. | |
| 5064 | |
| 5065 Various other new system configurations are supported. | |
| 5066 | |
| 5067 | |
| 5068 | |
| 5069 | |
| 5070 ** Major Differences Between 19.10 and 19.11 | |
| 5071 ============================================ | |
| 5072 | |
| 5073 The name has changed from "Lucid Emacs" to "XEmacs". Along with this is a | |
| 5074 new canonical ftp site: cs.uiuc.edu:/pub/xemacs. | |
| 5075 | |
| 5076 XEmacs now has its very own World Wide Web page! It contains a | |
| 5077 complete list of the FTP distribution sites, the most recent FAQ, | |
| 5078 pointers to Emacs Lisp packages not included with the distribution, and | |
| 5079 other useful stuff. Check it out at http://xemacs.cs.uiuc.edu/. | |
| 5080 | |
| 5081 A preliminary New Users Guide. | |
| 5082 | |
| 5083 cc-mode.el now provides the default C, C++ and Objective-C modes. | |
| 5084 | |
| 5085 The primary goal of this release is stability. Very few new features have | |
| 5086 been introduced but lots of bugs have been fixed. Many of the Emacs Lisp | |
| 5087 packages have been updated. | |
| 5088 | |
| 5089 Some of the new Emacs Lisp packages --- | |
| 5090 | |
| 5091 tcl-mode.el: major mode for editing TCL code | |
| 5092 | |
| 5093 fast-lock.el: saves and restores font-lock highlighting, greatly | |
| 5094 reducing the time necessary for loading a font-lock'ed | |
| 5095 file | |
| 5096 | |
| 5097 ps-print.el: prints buffers to Postscript printers preserving the | |
| 5098 buffer's bold and italic text attributes | |
| 5099 | |
| 5100 toolbar.el: provides a "fake" toolbar for use with XEmacs (an | |
| 5101 integrated one will be included with 19.12) | |
| 5102 | |
| 5103 | |
| 5104 ** Major Differences Between 19.9 and 19.10 | |
| 5105 =========================================== | |
| 5106 | |
| 5107 The GNU `configure' system is now used to build lemacs. | |
| 5108 | |
| 5109 The Emacs Manual and Emacs Lisp Reference Manual now document version 19.10. | |
| 5110 If you notice any errors, please let us know. | |
| 5111 | |
| 5112 When pixmaps are displayed in a buffer, they contribute to the line height - | |
| 5113 that is, if the glyph is taller than the rest of the text on the line, the | |
| 5114 line will be as tall as necessary to display the glyph. | |
| 5115 | |
| 5116 In addition to using arbitrary sound files as emacs beeps, one can control | |
| 5117 the pitch and duration of the standard X beep, on X servers which allow that | |
| 5118 (Note: most don't.) | |
| 5119 | |
| 5120 There is support for playing sounds on systems with NetAudio servers. | |
| 5121 | |
| 5122 Minor modes may have mode-specific key bindings; keymaps may have an arbitrary | |
| 5123 number of parent maps. | |
| 5124 | |
| 5125 Menus can have toggle and radio buttons in them. | |
| 5126 | |
| 5127 There is a font selection menu. | |
| 5128 | |
| 5129 Some default key bindings have changed to match FSF19; the new bindings are | |
| 5130 | |
| 5131 Screen-related commands: | |
| 5132 C-x 5 2 make-screen | |
| 5133 C-x 5 0 delete-screen | |
| 5134 C-x 5 b switch-to-buffer-other-screen | |
| 5135 C-x 5 f find-file-other-screen | |
| 5136 C-x 5 C-f find-file-other-screen | |
| 5137 C-x 5 m mail-other-screen | |
| 5138 C-x 5 o other-screen | |
| 5139 C-x 5 r find-file-read-only-other-screen | |
| 5140 Abbrev-related commands: | |
| 5141 C-x a l add-mode-abbrev | |
| 5142 C-x a C-a add-mode-abbrev | |
| 5143 C-x a g add-global-abbrev | |
| 5144 C-x a + add-mode-abbrev | |
| 5145 C-x a i g inverse-add-global-abbrev | |
| 5146 C-x a i l inverse-add-mode-abbrev | |
| 5147 C-x a - inverse-add-global-abbrev | |
| 5148 C-x a e expand-abbrev | |
| 5149 C-x a ' expand-abbrev | |
| 5150 Register-related commands: | |
| 5151 C-x r C-SPC point-to-register | |
| 5152 C-x r SPC point-to-register | |
| 5153 C-x r j jump-to-register | |
| 5154 C-x r s copy-to-register | |
| 5155 C-x r x copy-to-register | |
| 5156 C-x r i insert-register | |
| 5157 C-x r g insert-register | |
| 5158 C-x r r copy-rectangle-to-register | |
| 5159 C-x r c clear-rectangle | |
| 5160 C-x r k kill-rectangle | |
| 5161 C-x r y yank-rectangle | |
| 5162 C-x r o open-rectangle | |
| 5163 C-x r t string-rectangle | |
| 5164 C-x r w window-configuration-to-register | |
| 5165 Narrowing-related commands: | |
| 5166 C-x n n narrow-to-region | |
| 5167 C-x n w widen | |
| 5168 Other changes: | |
| 5169 C-x 3 split-window-horizontally (was undefined) | |
| 5170 C-x - shrink-window-if-larger-than-buffer | |
| 5171 C-x + balance-windows | |
| 5172 | |
| 5173 The variable allow-deletion-of-last-visible-screen has been removed, since | |
| 5174 it was widely hated. You can now always delete the last visible screen if | |
| 5175 there are other iconified screens in existence. | |
| 5176 | |
| 5177 ToolTalk support is provided. | |
| 5178 | |
| 5179 An Emacs screen can be placed within an "external client widget" managed | |
| 5180 by another application. This allows an application to use an Emacs screen | |
| 5181 as its text pane rather than the standard Text widget that is provided | |
| 5182 with Motif or Athena. | |
| 5183 | |
| 5184 Additional compatibility with Epoch is provided (though this is not yet | |
| 5185 complete.) | |
| 5186 | |
| 5187 | |
| 5188 ** Major Differences Between 19.8 and 19.9 | |
| 5189 ========================================== | |
| 5190 | |
| 5191 Scrollbars! If you have Motif, these are real Motif scrollbars; otherwise, | |
| 5192 Athena scrollbars are used. They obey all the usual resources of their | |
| 5193 respective toolkits. | |
| 5194 | |
| 5195 There is now an implementation of dialog boxes based on the Athena | |
| 5196 widgets, as well as the existing Motif implementation. | |
| 5197 | |
| 5198 This release works with Motif 1.2 as well as 1.1. If you link with Motif, | |
| 5199 you do not also need to link with Athena. | |
| 5200 | |
| 5201 If you compile lwlib with both USE_MOTIF and USE_LUCID defined (which is the | |
| 5202 recommended configuration) then the Lucid menus will draw text using the Motif | |
| 5203 string-drawing library, instead of the Xlib one. The reason for this is that | |
| 5204 one can take advantage of the XmString facilities for including non-Latin1 | |
| 5205 characters in resource specifications. However, this is a user-visible change | |
| 5206 in that, in this configuration, the menubar will use the "*fontList" resource | |
| 5207 in preference to the "*font" resource, if it is set. | |
| 5208 | |
| 5209 It's possible to make extents which are copied/pasted by kill and undo. | |
| 5210 There is an implementation of FSF19-style text properties based on this. | |
| 5211 | |
| 5212 There is a new variable, minibuffer-max-depth, which is intended to circumvent | |
| 5213 a common source of confusion among new Emacs users. Since, under a window | |
| 5214 system, it's easy to jump out of the minibuffer (by doing M-x, then getting | |
| 5215 distracted, and clicking elsewhere) many, many novice users have had the | |
| 5216 problem of having multiple minibuffers build up, even to the point of | |
| 5217 exhausting the lisp stack. So the default behavior is to disallow the | |
| 5218 minibuffer to ever be reinvoked while active; if you attempt to do so, you | |
| 5219 will be prompted about it. | |
| 5220 | |
| 5221 There is a new variable, teach-extended-commands-p, which if set, will cause | |
| 5222 `M-x' to remind you of any key bindings of the command you just invoked the | |
| 5223 "long way." | |
| 5224 | |
| 5225 There are menus in Dired, Tar, Comint, Compile, and Grep modes. | |
| 5226 | |
| 5227 There is a menu of window management commands on the right mouse button over | |
| 5228 the modelines. | |
| 5229 | |
| 5230 Popup menus now have titles at the top; this is controlled by the new | |
| 5231 variable `popup-menu-titles'. | |
| 5232 | |
| 5233 The `Find' key on Sun keyboards will search for the next (or previous) | |
| 5234 occurrence of the selected text, as in OpenWindows programs. | |
| 5235 | |
| 5236 The `timer' package has been renamed to `itimer' to avoid a conflict with | |
| 5237 a different package called `timer'. | |
| 5238 | |
| 5239 VM 5.40 is included. | |
| 5240 | |
| 5241 W3, the emacs interface to the World Wide Web, is included. | |
| 5242 | |
| 5243 Felix Lee's GNUS speedups have been installed, including his new version of | |
| 5244 nntp.el which makes GNUS efficiently utilize the NNTP XOVER command if | |
| 5245 available (which is much faster.) | |
| 5246 | |
| 5247 GNUS should also be much friendlier to new users: it starts up much faster, | |
| 5248 and doesn't (necessarily) subscribe you to every single newsgroup. | |
| 5249 | |
| 5250 The byte-compiler issues a new class of warnings: variables which are | |
| 5251 bound but not used. This is merely an advisory, and does not mean the | |
| 5252 code is incorrect; you can disable these warnings in the usual way with | |
| 5253 the `byte-compiler-options' macro. | |
| 5254 | |
| 5255 the `start-open' and `end-open' extent properties, for specifying whether | |
| 5256 characters inserted exactly at a boundary of an extent should go into the | |
| 5257 extent or out of it, now work correctly. | |
| 5258 | |
| 5259 The `extent-data' slot has been generalized/replaced with a property list, | |
| 5260 so it's easier to attach arbitrary data to extent objects. | |
| 5261 | |
| 5262 The `event-modifiers' and `event-modifier-bits' functions work on motion | |
| 5263 events as well as other mouse and keyboard events. | |
| 5264 | |
| 5265 Forms-mode uses fonts and read-only regions. | |
| 5266 | |
| 5267 The behavior of the -geometry command line option should be correct now. | |
| 5268 | |
| 5269 The `iconic' screen parameter works when passed to x-create-screen. | |
| 5270 | |
| 5271 The user's manual now documents Lucid Emacs 19.9. | |
| 5272 | |
| 5273 The relocating buffer allocator is turned on by default; this means that when | |
| 5274 buffers are killed, their storage will be returned to the operating system, | |
| 5275 and the size of the emacs process will shrink. | |
| 5276 | |
| 5277 CAVEAT: code which contains calls to certain `face' accessor functions will | |
| 5278 need to be recompiled by version 19.9 before it will work. The functions | |
| 5279 whose callers must be recompiled are: face-font, face-foreground, | |
| 5280 face-background, face-background-pixmap, and face-underline-p. The symptom | |
| 5281 of this problem is the error "Wrong type argument, arrayp, #<face ... >". | |
| 5282 The .elc files generated by version 19.9 will work in 19.6 and 19.8, but | |
| 5283 older .elc files which contain calls to these functions will not work in 19.9. | |
| 5284 | |
| 5285 Work In Progress: | |
| 5286 | |
| 5287 - We have been in the process of internationalizing Lucid Emacs. This code is | |
| 5288 ***not*** ready for general use yet. However, the code is included (and | |
| 5289 turned off by default) in this release. | |
| 5290 | |
| 5291 - If you define I18N2 at compile-time, then sorting/collation will be done | |
| 5292 according to the locale returned by setlocale(). | |
| 5293 | |
| 5294 - If you define I18N3 at compile-time, then all messages printed by lemacs | |
| 5295 will be filtered through the gettext() library routine, to enable the use | |
| 5296 of locale-specific translation catalogues. The current implementation of | |
| 5297 this is quite dependent on Solaris 2, and has a very large impact on | |
| 5298 existing code, therefore we are going to be making major changes soon. | |
| 5299 (You'll notice calls to `gettext' and `GETTEXT' scattered around much of | |
| 5300 the lisp and C code; ignore it, this will be going away.) | |
| 5301 | |
| 5302 - If you define I18N4 at compile-time, then lemacs will internally use a | |
| 5303 wide representation of characters, enabling the use of large character | |
| 5304 sets such as Kanji. This code is very OS dependent: it requires X11R5, | |
| 5305 and several OS-supplied library routines for reading and writing wide | |
| 5306 characters (getwc(), putwc(), and a few others.) Performance is also a | |
| 5307 problem. This code is also scheduled for a major overhaul, with the | |
| 5308 intent of improving performance and portability. | |
| 5309 | |
| 5310 Our eventual goal is to merge with MULE, or at least provide the same base | |
| 5311 level of functionality. If you would like to help out with this, let us | |
| 5312 know. | |
| 5313 | |
| 5314 - Other work-in-progress includes Motif drag-and-drop support, ToolTalk | |
| 5315 support, and support for embedding an Emacs widget inside another | |
| 5316 application (where it can function as that other application's text-entry | |
| 5317 area). This code has not been extensively tested, and may (or may not) | |
| 5318 have portability problems, but it's there for the adventurous. Comments, | |
| 5319 suggestions, bug reports, and especially fixes are welcome. But have no | |
| 5320 expectations that this experimental code will work at all. | |
| 5321 | |
| 5322 | |
| 5323 ** Major Differences Between 19.6 and 19.8 | |
| 5324 ========================================== | |
| 5325 | |
| 5326 There were almost no differences between versions 19.6 and 19.7; version 19.7 | |
| 5327 was a bug-fix release that was distributed with Energize 2.1. | |
| 5328 | |
| 5329 Lucid Emacs 19.8 represents the first stage of the Lucid Emacs/Epoch merger. | |
| 5330 The redisplay engine now in lemacs is an improved descendant of the Epoch | |
| 5331 redisplay. As a result, many bugs have been eliminated, and several disabled | |
| 5332 features have been re-enabled. Notably: | |
| 5333 | |
| 5334 Selective display (and outline-mode) work. | |
| 5335 | |
| 5336 Horizontally split windows work. | |
| 5337 | |
| 5338 The height of a line is the height of the tallest font displayed on that line; | |
| 5339 it is possible for a screen to display lines of differing heights. (Previously, | |
| 5340 the height of all lines was the height of the tallest font loaded.) | |
| 5341 | |
| 5342 There is lisp code to scale fonts up and down, for example, to load the next- | |
| 5343 taller version of a font. | |
| 5344 | |
| 5345 There is a new internal representation for lisp objects, giving emacs-lisp 28 | |
| 5346 bit integers and a 28 bit address space, up from the previous maximum of 26. | |
| 5347 We expect eventually to increase this to 30 bit integers and a 32 bit address | |
| 5348 space, eliminating the need for DATA_SEG_BITS on some architectures. (On 64 | |
| 5349 bit machines, add 32 to all of these numbers.) | |
| 5350 | |
| 5351 GC performance is improved. | |
| 5352 | |
| 5353 Various X objects (fonts, colors, cursors, pixmaps) are accessible as first- | |
| 5354 class lisp objects, with finalization. | |
| 5355 | |
| 5356 An alternate interface to embedding images in the text is provided, called | |
| 5357 "annotations." You may create an "annotation margin" which is whitespace at | |
| 5358 the left side of the screen that contains only annotations, not buffer text. | |
| 5359 | |
| 5360 When using XPM files, one can specify the values of logical color names to be | |
| 5361 used when loading the files. | |
| 5362 | |
| 5363 It is possible to resize windows by dragging their modelines up and down. More | |
| 5364 generally, it is possible to add bindings for mouse gestures on the modelines. | |
| 5365 | |
| 5366 There is support for playing sound files on HP machines. | |
| 5367 | |
| 5368 ILISP version 5.5 is included. | |
| 5369 | |
| 5370 The Common Lisp #' read syntax is supported (#' is to "function" as ' is to | |
| 5371 "quote".) | |
| 5372 | |
| 5373 The `active-p' slot of menu items is now evaluated, so one can put arbitrary | |
| 5374 lisp code in a menu to decide whether that item should be selectable, rather | |
| 5375 than doing this with an `activate-menubar-hook'. | |
| 5376 | |
| 5377 The X resource hierarchy has changed slightly, to be more consistent. It used | |
| 5378 to be | |
| 5379 argv[0] SCREEN-NAME pane screen | |
| 5380 ApplicationShell EmacsShell Paned EmacsFrame | |
| 5381 | |
| 5382 now it is | |
| 5383 | |
| 5384 argv[0] shell pane SCREEN-NAME | |
| 5385 ApplicationShell EmacsShell Paned EmacsFrame | |
| 5386 | |
| 5387 The Lucid Emacs sources have been largely merged with FSF version 19; this | |
| 5388 means that the lisp library contains the most recent releases of various | |
| 5389 packages, and many new features of FSF 19 have been incorporated. | |
| 5390 | |
| 5391 Because of this, the lemacs sources should also be substantially more portable. | |
| 5392 | |
| 5393 | |
| 5394 ** Major Differences Between 19.4 and 19.6 | |
| 5395 ========================================== | |
| 5396 | |
| 5397 There were almost no differences between versions 19.4 and 19.5; we fixed | |
| 5398 a few minor bugs and repacked 19.4 as 19.5 for a CD-ROM that we gave away | |
| 5399 as a trade show promotion. | |
| 5400 | |
| 5401 The primary goal of the 19.6 release is stability, rather than improved | |
| 5402 functionality, so there aren't many user-visible changes. The most notable | |
| 5403 changes are: | |
| 5404 | |
| 5405 - The -geometry command-line option now correctly overrides geometry | |
| 5406 specifications in the resource database. | |
| 5407 - The `width' and `height' screen-parameters work. | |
| 5408 - Font-lock-mode considers the comment start and end characters to be | |
| 5409 a part of the comment. | |
| 5410 - The lhilit package has been removed. Use font-lock-mode instead. | |
| 5411 - vm-isearch has been fixed to work with isearch-mode. | |
| 5412 - new versions of ispell and calendar. | |
| 5413 - sccs.el has menus. | |
| 5414 | |
| 5415 Lots of bugs were fixed, including the problem that lemacs occasionally | |
| 5416 grabbed the keyboard focus. | |
| 5417 | |
| 5418 Also, as of Lucid Emacs 19.6 and Energize 2.0 (shipping now) it is possible | |
| 5419 to compile the public release of Lucid Emacs with support for Energize; so | |
| 5420 now Energize users will be able to build their own Energize-aware versions | |
| 5421 of lemacs, and will be able to use newer versions of lemacs as they are | |
| 5422 released to the net. (Of course, this is not behavior covered by your | |
| 5423 Energize support contract; you do it at your own risk.) | |
| 5424 | |
| 5425 I have not incorporated all portability patches that I have been sent since | |
| 5426 19.4; I will try to get to them soon. However, if you need to make any | |
| 5427 changes to lemacs to get it to compile on your system, it would be quite | |
| 5428 helpful if you would send me context diffs (diff -c) against version 19.6. | |
| 5429 | |
| 5430 | |
| 5431 ** Major Differences Between 19.3 and 19.4 | |
| 5432 ========================================== | |
| 5433 | |
| 5434 Prototypes have been added for all functions. Emacs compiles in the strict | |
| 5435 ANSI modes of lcc and gcc, so portability should be vastly improved. | |
| 5436 | |
| 5437 Many many many many core leaks have been plugged, especially in screen | |
| 5438 creation and deletion. | |
| 5439 | |
| 5440 The float support reworked to be more portable and ANSI conformant. This | |
| 5441 resulted in these new configuration parameters: HAVE_INVERSE_HYPERBOLIC, | |
| 5442 HAVE_CBRT, HAVE_RINT, FLOAT_CHECK_ERRNO, FLOAT_CATCH_SIGILL, | |
| 5443 FLOAT_CHECK_DOMAIN. Let us know if you had to change the defaults on your | |
| 5444 architecture. | |
| 5445 | |
| 5446 The SunOS unexec has been rewritten, and now works with either static or | |
| 5447 dynamic libraries, depending on whether -Bstatic or -Bdynamic were specified | |
| 5448 at link-time. | |
| 5449 | |
| 5450 Small (character-sized) bitmaps can be mixed in with buffer text via the new | |
| 5451 functions set-extent-begin-glyph and set-extent-end-glyph. (This is actually | |
| 5452 a piece of functionality that Energize has been using for a while, but we've | |
| 5453 just gotten around to making it possible to use it without Energize. See how | |
| 5454 nice we are? Go buy our product.) | |
| 5455 | |
| 5456 If compiled with Motif support, one can pop up dialog boxes from emacs lisp. | |
| 5457 We encourage someone to contribute Athena an version of this code; it | |
| 5458 shouldn't be much work. | |
| 5459 | |
| 5460 If dialog boxes are available, then y-or-n-p and yes-or-no-p use dialog boxes | |
| 5461 instead of the minibuffer if invoked as a result of a command that was | |
| 5462 executed from a menu instead of from the keyboard. | |
| 5463 | |
| 5464 Multiple screen support works better; check out doc of get-screen-for-buffer. | |
| 5465 | |
| 5466 The default binding of backspace is the same as delete. (C-h is still help.) | |
| 5467 | |
| 5468 A middle click while the minibuffer is active does completion if you click on | |
| 5469 a highlighted completion, otherwise it executes the global binding of button2. | |
| 5470 | |
| 5471 New versions of Barry Warsaw's c++-mode and syntax.c. Font-lock-mode works | |
| 5472 with C++ mode now. | |
| 5473 | |
| 5474 The semantics of activate-menubar-hook has changed; the functions are called | |
| 5475 with no arguments now. | |
| 5476 | |
| 5477 `truename' no longer hacks the automounter; use directory-abbrev-alist instead. | |
| 5478 | |
| 5479 Most minibuffer handling has been reimplemented in emacs-lisp. | |
| 5480 | |
| 5481 There is now a builtin minibuffer history mechanism which replaces gmhist. | |
| 5482 | |
| 5483 | |
| 5484 ** Major Differences Between 19.2 and 19.3 | |
| 5485 ========================================== | |
| 5486 | |
| 5487 The ISO characters have correct case and syntax tables now, so the word-motion | |
| 5488 and case-converting commands work sensibly on them. | |
| 5489 | |
| 5490 If you set ctl-arrow to an integer, you can control exactly which characters | |
| 5491 are printable. (There will be a less crufty way to do this eventually.) | |
| 5492 | |
| 5493 Menubars can now be buffer local; the function set-screen-menubar no longer | |
| 5494 exists. Look at GNUS and VM for examples of how to do this, or read | |
| 5495 menubar.el. | |
| 5496 | |
| 5497 When emacs is reading from the minibuffer with completions, any completions | |
| 5498 which are visible on the screen will highlight when the mouse moves over them; | |
| 5499 clicking middle on a completion is the same as typing it at the minibuffer. | |
| 5500 Some implications of this: The *Completions* buffer is always mousable. If | |
| 5501 you're using the completion feature of find-tag, your source code will be | |
| 5502 mousable when you type M-. Dired buffers will be mousable as soon as you | |
| 5503 type ^X^F. And so on. | |
| 5504 | |
| 5505 The old isearch code has been replaced with a descendant of Dan LaLiberte's | |
| 5506 excellent isearch-mode; it is more customizable, and generally less bogus. | |
| 5507 You can search for "composed" characters. There are new commands, too; see | |
| 5508 the doc for ^S, or the NEWS file. | |
| 5509 | |
| 5510 A patched GNUS 3.14 is included. | |
| 5511 | |
| 5512 The user's manual now documents Lucid Emacs 19.3. | |
| 5513 | |
| 5514 A few more modes have mouse and menu support. | |
| 5515 | |
| 5516 The startup code should be a little more robust, and give you more reasonable | |
| 5517 error messages when things aren't installed quite right (instead of the | |
| 5518 ubiquitous "cannot open DISPLAY"...) | |
| 5519 | |
| 5520 Subdirectories of the lisp directory whose names begin with a hyphen or dot | |
| 5521 are not automatically added to the load-path, so you can use this to avoid | |
| 5522 accidentally inflicting experimental software on your users. | |
| 5523 | |
| 5524 I've tried to incorporate all of the portability patches that were sent to | |
| 5525 me; I tried to solve some of the problems in different ways than the | |
| 5526 patches did, so let me know if I missed something. | |
| 5527 | |
| 5528 Some systems will need to define NEED_STRDUP, NEED_REALPATH, HAVE_DREM, or | |
| 5529 HAVE_REMAINDER in config.h. Really this should be done in the appropriate | |
| 5530 s- or m- files, but I don't know which systems need these and which don't. | |
| 5531 If yours does, let me know which file it should be in. | |

| 5533 Check out these new packages: | |
| 5534 | |
| 5535 blink-paren.el: causes the matching parenthesis to flash on and off whenever | |
| 5536 the cursor is sitting on a paren-syntax character. | |
| 5537 | |
| 5538 pending-del.el: Certain commands implicitly delete the highlighted region: | |
| 5539 Typing a character when there is a highlighted region replaces | |
| 5540 that region with the typed character. | |
| 5541 | |
| 5542 font-lock.el: A code-highlighting package, driven off of syntax tables, so | |
| 5543 that it understands block comments, strings, etc. The | |
| 5544 insertion hook is used to fontify text as you type it in. | |
| 5545 | |
| 5546 shell-font.el: Displays your shell-buffer prompt in boldface. | |
