From 975a44e27f743cebd6965d9426b7f64e380ba7af Mon Sep 17 00:00:00 2001 From: "Richard M.

We hope you will enjoy the greater +simplicity that results from the absence of many newer features. @itemize @bullet @item -The display engine has been greatly simplified by eliminating support -for variable-size characters and other non-text display features. This -avoids the complexity of display layout in Emacs 21. To wit: +The input methods for Emacs are included in a separate distribution +called ``Leim''. To use them, you must extract the Leim tar file on +top of the Emacs distribution, into the same directory, before you +build Emacs. -@itemize @minus @item -Variable-size characters are not supported in Emacs 20. You cannot use -fonts which contain oversized characters, and using italic fonts can -result in illegible display. However, text which uses variable-size -fonts is unreadable anyway. With all characters in a frame laid out on -a regular grid, each character having the same height and width, text is -much easier to read. +The file position and line number information is now at the end +of the mode line. @item -Emacs does not display images, or play sounds. It just displays text, -as you would expect from a @strong{text} editor. +When a file is managed with version control, the command @kbd{C-x C-q} +(whose general meaning is to make a buffer read-only or writable) now +does so by checking the file in or out. Checking the file out makes +the buffer writable; checking it in makes the buffer read-only (at +least with RCS). -@item -Specification of the font for a face now uses an XLFD font name, for -compatibility with other X applications. This means that font -attributes cannot be merged when combining faces; however, experience -shows that mergers are bad economics. Face inheritance has also been -removed, so no one can accumulate ``too much face.'' - -@item -Several face appearance attributes, including 3D, strike-through, and -overline, have been eliminated. - -@item -Emacs now provides its own ``lean and mean'' scroll bars instead of using -those from the X toolkit. Toggle buttons and radio buttons in menus now -look just like any other menu item, which simplifies them, and prevents -them from standing out and distracting your attention from the other -menu items. - -@item -There are no toolbars and no tooltips; in particular, @acronym{GUD} -mode cannot display variable values in a tooltip when you click on -that variable's name. Instead, Emacs 20 provides a direct interface to -the debugger, so that you can type appropriate debugger commands, such -as @kbd{display foo} and @kbd{print bar}. As these commands use -explicit words, their meaning is more self-evident. - -@item -Colors are not available on text-only terminals. If you @emph{must} -have colors, but cannot afford to run X, you can now use the MS-DOG -version of Emacs inside a DOS emulator. - -@item -The mode line is not mouse-sensitive, since it is meant only to -display information. Use keyboard commands to switch between buffers, -toggle read-only and modified status, switch minor modes on and off, -etc. - -@item -The support for ``wheeled'' mice under X has been removed, because -of their slow scroll rate, and because you will find fewer and fewer of -these mice as you go back in time. Instead Emacs 20 provides the -@kbd{C-v} and @kbd{M-v} keys for scrolling. (You can also use the -scroll bar, but be advised that it, too, may be absent in yet earlier -Emacs versions.) - -@item -Busy-cursor display is gone, as it was found to be too hard to draw on -displays whose resolution is getting lower and lower. This means that -you get the standard kind of cursor blinking that your terminal -provides. - -@item -Some aspects of Emacs appearance, such as the colors of the scroll bar -and the menus, can only be controlled via X resources. Since colors -aren't supported except on X, it doesn't make any sense to do this in -any way but the X way. For those users who aren't privy to X arcana, -we've provided good default colors that should make everybody happy. +You can still use @kbd{C-x v v} to do these operations if you wish; +its meaning is unchanged. If you want to control the buffer's +read-only flag without performing any version control operation, +use @kbd{M-x toggle-read-only}. @item -Emacs 20 adds new lines to the buffer when you move down from the last -line with @kbd{C-n} or a down-arrow. +Filesets are not supported. @item -The variable @code{show-trailing-whitespace} has no special meaning, so -trailing whitespace on a line is now always displayed correctly: as -empty space. To see if a line ends with spaces or tabs, type @kbd{C-e} -on that line. Likewise, empty lines at the end of the buffer are not -marked in any way; use @kbd{M->} to see where the end of the buffer is. +For simplicity, windows always have fringes. We wouldn't want +to in-fringe anyone's windows. Likewise, horizontal scrolling +always works the same automatic way. @item -The spacing between text lines on the display now always follows the -font design and the rules of your window manager. This provides for -predictable appearance of the displayed text. -@end itemize - -@item -Emacs 20 has simpler support for multi-lingual editing. While not as -radical a simplification as Emacs 19 will be, it goes a long way toward -eliminating some of the annoying features: - -@itemize @minus -@item -Translations of the Emacs reference cards to other languages are no -longer part of the distribution, because in the past we expect -computer users to speak English. - -@item -To avoid extra confusion, many language environments have been -eliminated. For example, @samp{Polish} and @samp{Celtic} (Latin-8) -environments are not supported. The Latin-9 environment is gone, -too, because you won't need the Euro sign in the past. - -@item -Emacs 20 always asks you which coding system to use when saving -a buffer, unless it can use the same one that it used to read the buffer. -It does not try to see if the preferred coding system is suitable. +When you are logged in as root, all files now give you writable +buffers in Emacs reflecting the fact that you can write any files. @item -Commands which provide detailed information about character sets and -coding systems, such as @code{list-charset-chars}, -@code{describe-character-set}, and the @kbd{C-u C-x =} key-sequence, -no longer exist. The less said about non-ASCII characters, the -better. +Unicode support and unification between Latin-@var{n} character +sets have been removed. Cutting and pasting X selections does not +support ``extended segments'' so there are certain coding systems +it cannot handle. @item -The terminal coding system cannot be set to something CCL-based, so -keyboards which produce @code{KOI8} and DOS/Windows codepage codes -cannot be supported directly. Instead, you should use one of the input -methods provided in the Leim package. -@end itemize - -@item -As you move back through time, some systems will become unimportant or -enter the vaporware phase, so Emacs 20 does not support them: - -@itemize @minus -@item -Emacs 20 cannot be built on GNU/Linux systems running on IA64 machines, -and you cannot build a 64-bit Emacs on Solaris or Irix even though there -are still 64-bit versions of those OSes. - -@item -LynxOS is also not supported, and neither is the Macintosh, though they -still exist. -@end itemize +@kbd{C-w} in an incremental search always grabs an entire word +into the search string. More precisely, it grabs text through +the next end of a word. @item -The arrangement of menu bar items differs from most other @acronym{GUI} -programs. We think that uniformity of look-and-feel is boring, and that -Emacs' unique features require its unique menu-bar configuration. +Yanking now preserves all text properties that were in the killed +text. The variable @code{yank-excluded-properties} has no meaning. @item -You cannot save the options that you set from the @samp{Options} -menu-bar menu; instead, you need to set all the options again each time -you start a new session. However, if you follow the recommended -practice and keep a single Emacs session running until you log out, -you won't have to set the options very often. +Occur mode, Info mode, and Comint-derived modes now control +fontification in their own way, and @kbd{M-x font-lock-mode} +has nothing to do with it. To control fontification in Info +mode, use the variable @code{Info-fontify}. @item -Emacs 20 does not pop up a buffer with error messages when an error is -signaled during loading of the user's init file. Instead, it simply -announces the fact that an error happened. To know where in the init -file that was, insert @code{(message "foo")} lines judiciously into the -file and look for those messages in the @samp{*Messages*} buffer. +In Dired's @kbd{!} command, @samp{*} and @samp{?} now +cause substitution of the file names wherever they appear---not +only when they are surrounded by whitespace. @item -Some commands no longer treat Transient Mark mode specially. For -example, @code{ispell} doesn't spell-check the region when Transient -Mark mode is in effect and the mark is active; instead, it checks the -current buffer. (Transient Mark mode is alien to the spirit of Emacs, -so we are planning to remove it altogether in an earlier version.) +Minibuffer completion commands now always complete the entire +minibuffer contents, just as if you had typed them at the end +of the minibuffer, no matter where point is actually located. @item -@kbd{C-Down-Mouse-3} does not show what would be in the menu bar -when the menu bar is not displayed. +An unquoted @samp{$} in a file name is now an error, if the following +name is not recognized as an environment variable. Thus, +the file name @file{foo$bar} would probably be an error. Meanwhile, +the @code{setenv} command does not expand @samp{$} at all. @item -For uniformity, the @key{delete} function key in Emacs 20 works exactly like -the @key{DEL} key, on both text-only terminals and window systems---it -always deletes backward. This eliminates the inconsistency of Emacs 21, -where the key labeled @key{delete} deletes forward when you are using a -window system, and backward on a text-only terminals. +Commands to set the mark at a place away from point, including +@kbd{M-@}, @kbd{M-h}, etc., don't do anything special when you repeat +them. In most cases, typing these commands multiple times is +equivalent to using them once. @kbd{M-h} does not use its numeric +argument. @item -The ability to place backup files in special subdirectories (controlled -by @code{backup-directory-alist}) has been eliminated. This makes -finding your backup files much easier: they are always in the same -directory as the original files. +@kbd{C-@key{SPC} C-@key{SPC}} has no special meaning and neither does +@kbd{C-u C-x C-x}. @item -Emacs no longer refuses to load Lisp files compiled by incompatible -versions of Emacs, which may contain invalid byte-code. Instead, -Emacs now dumps core when it encounters such byte-code. However, this -is a rare occurrence, and it won't happen at all when all Emacs -versions merge together, in the distant past. +There is no horizontal-bar cursor. @item -The @kbd{C-x 5 1} command has been eliminated. If you want to delete -all the frames but the current one, delete them one by one instead. +The faces @code{minibuffer-prompt} and @code{mode-line-inactive} +do not exist, and the features they control don't exist either. @item -CC Mode now enforces identical values for some customizable options, -such as indentation style, for better consistency. In particular, if -you select an indentation style for Java, the same style is used -for C and C@t{++} buffers as well. +The default value of @code{keyboard-coding-system} is always @code{nil}. +Emacs does not set it based on your locale settings. +If you want some other value, you must set it yourself. @item -Isearch does not highlight other possible matches; it shows only the -current match, to avoid distracting your attention. @kbd{Mouse-2} in -the echo area during incremental search now signals an error, instead of -inserting the current selection into the search string. But you can -accomplish more or less the same job by typing @kbd{M-y}. +SGML mode does not handle XML syntax, and does not have indentation support. @item -The ability to specify a port number when editing remote files with -@code{ange-ftp} was removed. Instead, Emacs 20 provides undocumented -features in the function @code{ange-ftp-normal-login} (@cite{Use the -source, Luke!}) to specify the port. +The @kbd{C-h} subcommands have been rearranged--especially those that +display specific files. Type @kbd{C-h C-h} to see a list of these +commands; that will show you what is different. @item -Emacs 20 does not check for changing time stamps of remote files, since -the old FTP programs you will encounter in the past could not provide -the time stamp anyway. Windows-style FTP clients which output the -@samp{^M} character at the end of each line get special handling from -@code{ange-ftp} in Emacs 20, with unexpected results that should make -your life more interesting. +Emacs does not read @file{~/.abbrev_defs} automatically; if you want +to load abbrev definitions from a file, you must always do so +explicitly. @item -Many complicated display features, including highlighting of -mouse-sensitive text regions and popping up help strings for menu items, -don't work in the MS-DOS version. Spelling doesn't work on MS-DOS, -and Eshell doesn't exist, so there's no workable shell-mode, either. -This fits the spirit of MS-DOS, which resembles a dumb character -terminal. +The @samp{--fullwidth}, @samp{--fullheight} and @samp{--fullscreen} +command line options are not supported. @item -The @code{woman} package has been removed, so Emacs users on non-Posix -systems will need @emph{a real man} to read manual pages. (Users who -are not macho can read the Info documentation instead.) +The @samp{--geometry} option now entirely applies only to the initial +frame. @item -@code{recentf} has been removed, because we figure that you can remember -the names of the files you edit frequently. With decreasing disk size, -you should have fewer files anyway, so you won't notice the absence of -this feature. +Many commands have been removed from the menus or rearranged. @item -The @code{field} property does not exist in Emacs 20, so various -packages that run subsidiary programs in Emacs buffers cannot in general -distinguish which text was user input and which was output from the -subprocess. If you need to try to do this nonetheless, Emacs 20 -provides a variable @code{comint-prompt-regexp}, which lets you try to -distinguish input by recognizing prompt strings. +Many @code{etags} features for customizing parsing using regexps +have been removed. @item -We have eliminated the special major modes for Delphi sources, -PostScript files, context diffs, and @file{TODO} files. Use Fundamental -Mode instead. +The CUA, ido, table, tramp, reveal, ruler-mode, and ibuffer packages +have been removed. So has the spreadsheet, SES, and the algebraic +calculator, Calc. (We distribute Calc separately.) @item -Many additional packages that unnecessarily complicate your life in -Emacs 21 are absent in Emacs 20. You cannot browse C@t{++} classes with -Ebrowse, access @acronym{SQL} data bases, access @acronym{LDAP} and -other directory servers, or mix shell commands and Lisp functions using -Eshell. +The kmacro package has been removed. To start a keyboard macro you +must use @kbd{C-x (}; to end one, @kbd{C-x )}; to execute the last +one, @kbd{C-x e}. @item To keep up with decreasing computer memory capacity and disk space, many -other functions and files have been eliminated in Emacs 20. +other functions and files have been eliminated in Emacs 21.3. @end itemize -- 2.39.2
