We hope you will enjoy the +greater simplicity that results from the absence of many Emacs +@value{EMACSVER} features. @itemize @bullet - -@item -The buffer position and line number are now displayed at the end of -the mode line, where they can be more easily seen. - -@item -The mode line of the selected window is no longer displayed with a -special face. All mode lines are created equal. Meanwhile, you can -use the variable @code{mode-line-inverse-video} to control whether -mode lines are highlighted at all---@code{nil} means don't highlight -them. - -@item -Clicking on a link with the left mouse button (@kbd{mouse-1}) will -always set point at the position clicked, instead of following the -link. If you want to follow the link, use the middle mouse button -(@kbd{mouse-2}). - -@item -Emacs is tired of X droppings. If you drop a file or a piece of text -onto an Emacs window, nothing will happen. - -@item -On an xterm, even if you enable Xterm Mouse mode, Emacs provides a -more convincing simulation of a text terminal by not responding to -mouse clicks on the mode line, header line, or display margin. - -@item -For simplicity, windows always have fringes. We wouldn't want to -in-fringe anyone's windows. Likewise, horizontal scrolling always -works in the same automatic way. - -@item -The horizontal-bar cursor shape has been removed. - -@item -If command line arguments are given, Emacs will not display a splash -screen, so that you can immediately get on with your editing. The -command-line option @samp{--no-splash} is therefore obsolete, and has -been removed. - -@item -These command line options have also been removed: @samp{--color}, -@samp{--fullwidth}, @samp{--fullheight}, @samp{--fullscreen}, -@samp{--no-blinking-cursor}, @samp{--no-desktop}, and @samp{-Q}. - -@item -The @samp{--geometry} option applies only to the initial frame, and -the @samp{-f} option will not read arguments for interactive -functions. - -@item -We have standardized on one location for the user init file: the file -named @file{.emacs} in your home directory. Emacs will not look for -the init file in @file{~/.emacs.d/init.el}. Similarly, don't try -putting @file{.emacs_SHELL} as @file{init_SHELL.sh} in -@file{~/.emacs.d}; Emacs won't find it. - -@item -Emacs will not read @file{~/.abbrev_defs} automatically. If you want -to load abbrev definitions from a file, you must always do so -explicitly. - -@item -When you are logged in as root, all files now give you writable -buffers, reflecting the fact that you can write any files. - -@item -The maximum size of buffers and integer variables has been halved. On -32-bit machines, the maximum buffer size is now 128 megabytes. - -@item -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 -If a single command accumulates too much undo information, Emacs never -discards it. If Emacs runs out of memory as a result, it will handle -this by crashing. - -@item -Many commands have been removed from the menus or rearranged. - -@item -The @kbd{C-h} (help) 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 -The @kbd{C-h v} and @kbd{C-h f} commands no longer show a hyperlink to -the C source code, even if it is available. If you want to find the -source code, grep for it. - -@item -The apropos commands will not accept a list of words to match, in -order to encourage you to be more specific. Also, the user option -@code{apropos-sort-by-scores} has been removed. - -@item -The minibuffer prompt is now displayed using the default face. -The colon is enough to show you what part is the prompt. - @item -Minibuffer completion commands 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. +Support for displaying and editing ``bidirectional'' text has been +removed. Text is now always displayed on the screen in a single +consistent direction---left to right---regardless of the underlying +script. Similarly, @kbd{C-f} and @kbd{C-b} always move the text +cursor to the right and left respectively. Also, @key{right} and +@key{left} are now equivalent to @kbd{C-f} and @kbd{C-b}, as you might +expect, rather than moving forward or backward based on the underlying +``paragraph direction''. -@item -The command @code{backward-kill-sexp} is now bound to @kbd{C-M-delete} -and @kbd{C-M-backspace}. Be careful when using these key sequences! -It may shut down your X server, or reboot your operating system. - -@item -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 typing them once. @kbd{M-h} ignores numeric arguments. - -@item -The user option @code{set-mark-command-repeat-pop} has been removed. - -@item -@kbd{C-@key{SPC} C-@key{SPC}} has no special meaning--it just sets the -mark twice. Neither does @kbd{C-u C-x C-x}, which simply exchanges -point and mark like @kbd{C-x C-x}. - -@item -The function @code{sentence-end} has been eliminated in favor of a -more straightforward approach: directly setting the variable -@code{sentence-end}. For example, to end each sentence with a single -space, use - -@lisp -(setq sentence-end "[.?!][]\"')@}]*\\($\\|[ \t]\\)[ \t\n]*") -@end lisp - -@item -The variable @code{fill-nobreak-predicate} is no longer customizable, -and it can only hold a single function. - -@item -Nobreak spaces and hyphens are displayed just like normal characters, -and the user option @code{nobreak-char-display} has been removed. - -@item -@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 -Yanking now preserves all text properties that were in the killed -text. The variable @code{yank-excluded-properties} has been removed. - -@item -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 -@samp{M-x shell} is now completely standard in regard to scrolling -behavior. It no longer has the option of scrolling the input line to -the bottom of the window the way a text terminal running a shell does. +Users of ``right-to-left'' languages, like Arabic and Hebrew, may +adapt by reading and/or editing text in left-to-right order. @item -The Grep package has been merged with Compilation mode. Many -grep-specific commands and user options have thus been eliminated. -Also, @kbd{M-x grep} never tries the GNU grep @samp{-H} option, -and instead silently appends @file{/dev/null} to the command line. +The Emacs Lisp package manager has been removed. Instead of using a +``user interface'' (@kbd{M-x list-packages}), additional Lisp packages +must now be installed by hand, which is the most flexible and +``Lispy'' method anyway. Typically, this just involves editing your +init file to add the package installation directory to the load path +and defining some autoloads; see each package's commentary section +and/or README file for details. @item -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. +The option @code{delete-active-region} has been deleted. When the +region is active, typing @key{DEL} or @key{delete} no longer deletes +the text in the region; it deletes a single character instead. @item -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. +We have reworked how Emacs handles the clipboard and the X primary +selection. Commands for killing and yanking, like @kbd{C-w} and +@kbd{C-y}, use the primary selection and not the clipboard, so you can +use these commands without interfering with ``cutting'' or ``pasting'' +in other programs. The @samp{Cut}/@samp{Copy}/@samp{Paste} menu items +are bound to separate clipboard commands, not to the same commands as +@kbd{C-w}/@kbd{M-w}/@kbd{C-y}. -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}. +Selecting text by dragging with the mouse now puts the text in the +kill ring, in addition to the primary selection. But note that +selecting an active region with @kbd{C-@key{SPC}} does @emph{not} +alter the kill ring nor the primary selection, even though the text +highlighting is visually identical. @item -SGML mode does not handle XML syntax, and does not have indentation -support. +In Isearch, @kbd{C-y} and @kbd{M-y} are no longer bound to +@code{isearch-yank-kill} and @code{isearch-yank-pop} respectively. +Instead, @kbd{C-y} yanks the rest of the current line into the search +string (@code{isearch-yank-line}), whereas @kbd{M-y} does +@code{isearch-yank-kill}. The mismatch with the usual meanings of +@kbd{C-y} and @kbd{M-y} is unintended. @item -Many Info mode commands have been removed. Incremental search in Info -searches only the current node. +Various completion features have been simplified. The options +@code{completion-cycle-threshold} and +@code{completion-category-overrides} have been removed. Due to the +latter removal, Emacs uses a single consistent scheme to generate +completions, instead of using a separate scheme for (say) buffer name +completion. Several major modes, such as Shell mode, now implement +their own inline completion commands instead of using +@code{completion-at-point}. @item -Many @code{etags} features for customizing parsing using regexps -have been removed. +We have removed various options for controlling how windows are used, +e.g.@: @code{display-buffer-base-action}, @code{display-buffer-alist}, +@code{window-combination-limit}, and @code{window-combination-resize}. @item -The Emacs server now runs a small C program called @file{emacsserver}, -rather than trying to handle everything in Emacs Lisp. Now there can -only be one Emacs server running at a time. The @code{server-mode} -command and @code{server-name} user option have been eliminated. +The command @kbd{M-x customize-themes} has been removed. Emacs no +longer comes with pre-defined themes (you can write your own). @item -The @file{emacsclient} program no longer accepts the @samp{--eval}, -@samp{--display} and @samp{--server-file} command line options, and -can only establish local connections using Unix domain sockets. +Emacs no longer adapts various aspects of its display to GTK+ +settings, opting instead for a uniform toolkit-independent look. GTK+ +scroll bars are placed on the left, the same position as non-GTK+ X +scroll bars. Emacs no longer refers to GTK+ to set the default +@code{region} face, nor for drawing tooltips. @item -The command @code{quail-show-key}, for showing how to input a -character, has been removed. +Setting the option @code{delete-by-moving-to-trash} to a +non-@code{nil} now causes all file deletions to use the system trash, +even temporary files created by Lisp programs; furthermore, the +@kbd{M-x delete-file} and @kbd{M-x delete-directory} commands no +longer accept prefix arguments to force true deletion. @item -The default value of @code{keyboard-coding-system} is always -@code{nil}, regardless of your locale settings. If you want some -other value, set it yourself. +On GNU/Linux and Unix, the default method for sending mail (as +specified by @code{send-mail-function}) is to use the +@command{sendmail} program. Emacs no longer asks for a delivery +method the first time you try to send mail, trusting instead that the +system is configured for mail delivery, as it ought to be. @item -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 input methods for Emacs are included in a separate distribution -called ``Leim.'' To use this, you must extract the Leim tar file on -top of the Emacs distribution, into the same directory, before you -build Emacs. - -@item -The following input methods have been eliminated: belarusian, -bulgarian-bds, bulgarian-phonetic, chinese-sisheng, croatian, dutch, -georgian, latin-alt-postfix, latin-postfix, latin-prefix, -latvian-keyboard, lithuanian-numeric, lithuanian-keyboard, -malayalam-inscript, rfc1345, russian-computer, sgml, slovenian, -tamil-inscript ucs, ukrainian-computer, vietnamese-telex, and welsh. - -@item -The following language environments have been eliminated: Belarusian, -Bulgarian, Chinese-EUC-TW, Croatian, French, Georgian, Italian, -Latin-6, Latin-7, Latvian, Lithuanian, Malayalam, Russian, Russian, -Slovenian, Swedish, Tajik, Tamil, UTF-8, Ukrainian, Ukrainian, Welsh, -and Windows-1255. - -@item -The @code{code-pages} library, which contained various 8-bit coding -systems, has been removed. - -@item -The Kmacro package has been replaced with a simple and elegant -keyboard macro system. Use @kbd{C-x (} to start a new keyboard macro, -@kbd{C-x )} to end the macro, and @kbd{C-x e} to execute the last -macro. Use @kbd{M-x name-last-kbd-macro} to name the most recently -defined macro. - -@item -Emacs no longer displays your breakpoints in the source buffer, so you -have to remember where you left them. It can be difficult to inspect -the state of your debugged program from the command line, so Emacs -tries to demonstrate this in the GUD buffer. - -@item -The Calc, CUA, Ibuffer, Ido, Password, Printing, Reveal, -Ruler-mode, SES, Table, Tramp, and URL packages have been removed. -The Benchmark, Cfengine, Conf, Dns, Flymake, Python, Thumbs, and -Wdired modes have also been removed. - -@item -The Emacs Lisp Reference Manual and the Introduction to Programming in -Emacs Lisp are now distributed separately, not in the Emacs -distribution. - -@item -On MS Windows, there is no longer any support for tooltips, images, -sound, different mouse pointer shapes, or pointing devices with more -than 3 buttons. If you want these features, consider switching to -another operating system. But even if you don't want these features, -you should still switch---for freedom's sake. - -@item -Emacs will not use Unicode for clipboard operations on MS Windows. +Several VC features have been removed, including the @kbd{C-x v +} and +@kbd{C-x v m} commands for pulling and merging on distributed version +control systems, and the ability to view inline log entries in the log +buffers made by @kbd{C-x v L}. @item To keep up with decreasing computer memory capacity and disk space, many -other functions and files have been eliminated in Emacs 21.4. +other functions and files have been eliminated in Emacs 23.4. @end itemize - -@ignore - arch-tag: 32932bd9-46f5-41b2-8a0e-fb0cc4caeb29 -@end ignore
