Glenn Morris committed Mar 10, 2010 25 * Installation Changes in Emacs 24.1  Chong Yidong committed Jun 24, 2008 26   Glenn Morris committed Jun 10, 2010 27 28 29 30 31 32 33 ** Configure links against libselinux if it is found. You can disable this by using --without-selinux. --- ** By default, the installed Info and man pages are compressed. You can disable this by configuring --without-compress-info.  Glenn Morris committed Mar 17, 2010 34 35 36 37 38 39 --- ** There are new configure options: --with-mmdf, --with-mail-unlink, --with-mailhost. These provide no new functionality, they just remove the need to edit lib-src/Makefile by hand in order to use the associated features.  Jan D committed Jun 28, 2010 40 ---  Michael Mauger committed Jul 18, 2010 41 ** Emacs can be compiled against Gtk+ 3.0 if you pass --with-x-toolkit=gtk3  Jan D committed Jun 28, 2010 42 43 44 45 to configure. Note that other libraries used by Emacs, RSVG and GConf, also depend on Gtk+. You can disable them with --without-rsvg and --without-gconf.  Dan Nicolaescu committed Jul 02, 2010 46 47 ** There is a new configure option --enable-use-lisp-union-type. This is only useful for Emacs developers to debug certain types of bugs.  Esa Peuha committed Sep 18, 2010 48 This is not a new feature; only the configure flag is new.

(They were declared obsolete in Emacs 23.)  Chong Yidong committed Aug 22, 2010 61   Glenn Morris committed Jan 06, 2011 62 63 64 ** New command line option --no-site-lisp' removes site-lisp directories from load-path. -Q now implies this.  Juanma Barranquero committed Mar 16, 2011 65 66 ** On Windows, Emacs now warns when the obsolete _emacs init file is used.  Glenn Morris committed May 22, 2007 67   Glenn Morris committed Mar 10, 2010 68 * Changes in Emacs 24.1  Alan Mackenzie committed Jun 15, 2009 69   Stefan Monnier committed Mar 30, 2011 70 71 72 ** Completion in a non-minibuffer now tries to detect the end of completion and pops down the *Completions* buffer accordingly.  Chong Yidong committed Oct 02, 2010 73 74 75 ** emacsclient changes *** New emacsclient argument --parent-id ID can be used to open a  Chong Yidong committed May 29, 2010 76 77 78 client frame in parent X window ID, via XEmbed. This works like the --parent-id argument to Emacs.  Glenn Morris committed Mar 02, 2011 79 +++  Glenn Morris committed Mar 02, 2011 80 81 *** New emacsclient argument -q/--quiet suppresses some status messages.  Chong Yidong committed Oct 02, 2010 82 83 84 *** If emacsclient shuts down as a result of Emacs signalling an error, its exit status is 1.  Stefan Monnier committed May 11, 2010 85 86 ** Completion can cycle, depending on completion-cycle-threshold.  Leo Liu committed Mar 20, 2011 87 88 89 ** completing-read' can be customized using the new variable completing-read-function'  Stefan Monnier committed Mar 30, 2010 90 91 ** auto-mode-case-fold is now enabled by default.  Eli Zaretskii committed Mar 29, 2010 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 +++ ** Emacs now supports display and editing of bidirectional text. See the node "Bidirectional Editing" in the Emacs Manual for some initial documentation. To turn this on in any given buffer, set the buffer-local variable bidi-display-reordering' to a non-nil value. The default is nil. The buffer-local variable bidi-paragraph-direction', if non-nil, forces each paragraph in the buffer to have its base direction according to the value of this variable. Possible values are right-to-left' and left-to-right'. If the value is nil (the default), Emacs determines the base direction of each paragraph from its text, as specified by the Unicode Bidirectional Algorithm.  Eli Zaretskii committed May 15, 2010 108 109 110 The function current-bidi-paragraph-direction' returns the actual value of paragraph base direction at point.  Eli Zaretskii committed Mar 29, 2010 111 112 113 114 Reordering of bidirectional text for display in Emacs is a "Full bidirectionality" class implementation of the Unicode Bidirectional Algorithm.  Eli Zaretskii committed May 07, 2010 115 116 117 118 Note that some advanced display features, such as overlay strings and display' text properties, do not yet work correctly when bidirectional text is reordered for display.  Chong Yidong committed Mar 15, 2010 119 ** GTK scroll-bars are now placed on the right by default.  Chong Yidong committed Mar 12, 2010 120 121 Use set-scroll-bar-mode' to change this.  Jan Djärv committed Apr 21, 2010 122 ** GTK tool bars can have just text, just images or images and text.  Glenn Morris committed Apr 22, 2010 123 Customize tool-bar-style' to choose style. On a Gnome desktop, the default  Jan Djärv committed Apr 21, 2010 124 125 is taken from the desktop settings.  Jan Djärv committed Jul 29, 2010 126 127 ** GTK tool bars can be placed on the left/right or top/bottom of the frame. The frame-parameter tool-bar-position controls this. It takes the values  Jan D committed Aug 13, 2010 128 top, left, right or bottom. The Options => Show/Hide menu has entries  Jan Djärv committed Jul 29, 2010 129 130 for this.  Glenn Morris committed Sep 08, 2010 131 ** ImageMagick support.  Glenn Morris committed Sep 27, 2010 132 133 134 It is now possible to use the ImageMagick library to load many new image formats in Emacs. By default, Emacs links with the ImageMagick libraries if they are present at build time. To disable this, use  Lars Magne Ingebrigtsen committed Sep 27, 2010 135 the configure option --without-imagemagick'.  Joakim Verona committed Aug 18, 2010 136   Glenn Morris committed Sep 08, 2010 137 138 139 The new function imagemagick-types' returns a list of image file extensions that your installation of ImageMagick supports. The function imagemagick-register-types' enables ImageMagick support for  Esa Peuha committed Sep 18, 2010 140 these image types, minus those listed in imagemagick-types-inhibit'.  Joakim Verona committed Aug 18, 2010 141   Glenn Morris committed Sep 08, 2010 142 See the Emacs Lisp Reference Manual for more information.  Joakim Verona committed Aug 18, 2010 143   Jan D committed Aug 11, 2010 144 145 146 ** The colors for selected text (the region face) are taken from the GTK theme when Emacs is built with GTK.  Jan D committed Aug 01, 2010 147 148 149 ** Emacs uses GTK tooltips by default if built with GTK. You can turn that off by customizing x-gtk-use-system-tooltips.  Jan Djärv committed Apr 11, 2010 150 ** Lucid menus and dialogs can display antialiased fonts if Emacs is built  Jan Djärv committed Feb 14, 2011 151 152 with Xft. To change font, use the X resource font, for example: Emacs.pane.menubar.font: Courier-12  Jan Djärv committed Apr 08, 2010 153   Eli Zaretskii committed Nov 13, 2010 154 155 156 157 158 159 160 161 162 163 164 165 +++ ** Enhanced support for characters that have no glyphs in available fonts If a character has no glyphs in any of the available fonts, Emacs by default will display it either as a hexadecimal code in a box or as a thin 1-pixel space. In addition to these two methods, Emacs can display these characters as empty box, as an acronym, or not display them at all. To change how these characters are displayed, customize the variable glyphless-char-display-control'. On character terminals these methods are used for characters that cannot be encoded by the terminal-coding-system'.  Chong Yidong committed Oct 19, 2010 166 167 ** On graphical displays, the mode-line no longer ends in dashes.  Jan Djärv committed Mar 27, 2011 168 169 170 ** On Nextstep/OSX, the menu bar can be hidden by customizing ns-auto-hide-menu-bar.  Glenn Morris committed Apr 20, 2010 171 172 173 ** Basic SELinux support has been added. This requires Emacs to be linked with libselinux at build time.  Glenn Morris committed Apr 22, 2010 174 175 176 177 *** Emacs preserves the SELinux file context when backing up, and optionally when copying files. To this end, copy-file has an extra optional argument, and backup-buffer and friends include the SELinux context in their return values.  Glenn Morris committed Apr 20, 2010 178 179 180 181  *** The new functions file-selinux-context and set-file-selinux-context get and set the SELinux context of a file.  Michael Albinus committed Apr 23, 2010 182 183 184 *** Tramp offers handlers for file-selinux-context and set-file-selinux-context for remote machines which support SELinux.  Paul Eggert committed Jan 31, 2011 185 186 187 188 +++ ** The function format-time-string now supports the %N directive, for higher-resolution time stamps.  Glenn Morris committed Oct 01, 2010 189 ** The function kill-emacs is now run upon receipt of the signals SIGTERM  Eli Zaretskii committed Oct 02, 2010 190 and SIGHUP, and upon SIGINT in batch mode.  Glenn Morris committed Oct 01, 2010 191 192  ** kill-emacs-hook is now also run in batch mode.  Glenn Morris committed Mar 05, 2011 193 194 If you have code that adds something to kill-emacs-hook, you should consider if it is still appropriate to add it in the noninteractive case.  Glenn Morris committed Oct 01, 2010 195   Juri Linkov committed Apr 06, 2010 196 ** New scrolling commands scroll-up-command' and scroll-down-command'  Juanma Barranquero committed Mar 19, 2011 197 198 (bound to C-v/[next] and M-v/[prior]) do not signal errors at top/bottom of buffer at first key-press (instead move to top/bottom of buffer)  Juri Linkov committed Apr 14, 2010 199 when a new variable scroll-error-top-bottom' is non-nil.  Juri Linkov committed Apr 06, 2010 200   Juri Linkov committed Apr 06, 2010 201 202 203 ** New scrolling commands scroll-up-line' and scroll-down-line' scroll a line instead of full screen.  Juri Linkov committed Apr 16, 2010 204 ** New property scroll-command' should be set on a command's symbol to  Esa Peuha committed Sep 18, 2010 205 define it as a scroll command affected by scroll-preserve-screen-position'.  Juri Linkov committed Apr 14, 2010 206   Eli Zaretskii committed Mar 31, 2011 207 208 209 210 211 212 213 214 215 216 217 218 219 220 +++ ** If you customize scroll-conservatively' to a value greater than 100, Emacs will never recenter point in the window when it scrolls due to cursor motion commands or commands that move point (e.f., M-g M-g'). Previously, you needed to use most-positive-fixnum' as the value of scroll-conservatively' to achieve the same effect. --- ** Aggressive'' scrolling now honors the scroll margins. If you customize scroll-up-aggressively' or scroll-down-aggressively' and move point off the window, Emacs now scrolls the window so as to avoid positioning point inside the scroll margin.  Chong Yidong committed May 27, 2010 221 222 223 224 225 226 227 228 ** Trash changes *** delete-by-moving-to-trash' now only affects commands that specify trashing. This avoids inadvertently trashing temporary files. *** Calling delete-file' or delete-directory' with a prefix argument now forces true deletion, regardless of delete-by-moving-to-trash'.  Juri Linkov committed Jun 14, 2010 229 230 231 ** New option list-colors-sort' defines the color sort order for list-colors-display'.  Chong Yidong committed Jun 16, 2010 232 233 ** An Emacs Lisp package manager is now included. This is a convenient way to download and install additional packages,  Chong Yidong committed Oct 31, 2010 234 from a package repository at elpa.gnu.org.  Chong Yidong committed Aug 25, 2010 235 236 237 238 239  *** M-x list-packages' shows a list of packages, which can be selected for installation. *** New command describe-package', bound to C-h P'.  Chong Yidong committed Jun 16, 2010 240 241 242 243 244 245  *** By default, all installed packages are loaded and activated automatically when Emacs starts up. To disable this, set package-enable-at-startup' to nil. To change which packages are loaded, customize package-load-list'.  Christian Ohler committed Jan 13, 2011 246 247 248 249 ** An Emacs Lisp testing tool is now included. Emacs Lisp developers can use this tool to write automated tests for their code. See the ERT info manual for details.  Chong Yidong committed Oct 11, 2010 250 251 252 253 ** Custom Themes *** M-x customize-themes' lists Custom themes which can be enabled.  Chong Yidong committed Oct 16, 2010 254 255 256 257 258 *** New option custom-theme-load-path' is the load path for themes. Emacs no longer looks for custom themes in load-path'. The default is to search in custom-theme-directory', followed by a built-in theme directory named "themes/" in data-directory'.  Chong Yidong committed Jan 08, 2011 259 260 261 262 *** New option custom-safe-themes' records known-safe theme files. If a theme is not in this list, Emacs queries before loading it, and offers to save the theme to custom-safe-themes' automatically. By default, all themes included in Emacs are treated as safe.  Chong Yidong committed Jan 08, 2011 263   Michael Albinus committed Oct 03, 2010 264 265 266 ** The user option remote-file-name-inhibit-cache' controls whether the remote file-name cache is used for read access.  Glenn Morris committed Oct 22, 2010 267 268 269 ** The standalone programs lib-src/digest-doc and sorted-doc have been replaced with Lisp commands doc-file-to-man' and doc-file-to-info'.  Chong Yidong committed Dec 20, 2010 270 271 ** The variable focus-follows-mouse' now always defaults to nil.  Glenn Morris committed May 22, 2007 272   Glenn Morris committed Mar 10, 2010 273 * Editing Changes in Emacs 24.1  Chong Yidong committed Jun 26, 2008 274   Chong Yidong committed Mar 06, 2011 275 276 277 278 279 280 281 282 283 ** Search changes +++ *** C-y in Isearch is now bound to isearch-yank-kill, instead of isearch-yank-line. +++ *** M-s C-e in Isearch is now bound to isearch-yank-line.  Glenn Morris committed Nov 12, 2010 284 285 286 +++ ** There is a new command count-words-region', which does what you expect.  Stefan Monnier committed Dec 06, 2010 287 ** completion-at-point now handles tags and semantic completion.  Chong Yidong committed Apr 28, 2010 288   Michael Albinus committed Nov 21, 2010 289 290 ** The default value of backup-by-copying-when-mismatch' is now t.  Chong Yidong committed Dec 16, 2010 291 292 293 ** The command just-one-space' (C-SPC), if given a negative argument, also deletes newlines around point.  Chong Yidong committed Jun 27, 2010 294 295 296 297 298 299 300 301 ** Deletion changes *** New option delete-active-region'. If non-nil, C-d, [delete], and DEL delete the region if it is active and no prefix argument is given. If set to kill', these commands kill instead. *** New command delete-forward-char', bound to C-d and [delete].  Chong Yidong committed Oct 31, 2010 302 303 This is meant for interactive use, and obeys delete-active-region'. The command delete-char' does not obey delete-active-region'.  Chong Yidong committed Jun 27, 2010 304 305 306 307 308 309 310 311  *** delete-backward-char' is now a Lisp function. Apart from obeying delete-active-region', its behavior is unchanged. However, the byte compiler now warns if it is called from Lisp; you should use delete-char with a negative argument instead. *** The option mouse-region-delete-keys' has been deleted.  Chong Yidong committed Jul 14, 2010 312 313 ** Selection changes.  Chong Yidong committed Jan 27, 2011 314 315 316 317 318 319 320 321 322 323 324 325 326 327 328 329 330 331 332 333 334 335 336 337 338 339 340 341 342 343 344 345 346 347 348 349 350 351 352 353 354 355 The default handling of clipboard and primary selections was changed to conform with modern X applications. In short, most commands for killing and yanking text now use the clipboard, while mouse commands use the primary selection. In the following, we provide a list of these changes, followed by a list of steps to get the old behavior back if you prefer that. *** mouse-drag-copy-region' now defaults to nil. *** select-active-regions' now defaults to t. Merely selecting text (e.g. with drag-mouse-1) no longer puts it in the kill-ring. The selected text is put in the primary selection, if the system possesses a separate primary selection facility (e.g. X). **** select-active-regions' also accepts a new value, only'. This means to only set the primary selection for temporarily active regions (usually made by mouse-dragging or shift-selection); "ordinary" active regions, such as those made with C-SPC followed by point motion, do not alter the primary selection. *** mouse-2 is now bound to mouse-yank-primary'. This pastes from the primary selection, ignoring the kill-ring. Previously, mouse-2 was bound to mouse-yank-at-click'. *** x-select-enable-clipboard' now defaults to t on all platforms. *** x-select-enable-primary' now defaults to nil. Thus, commands that kill text or copy it to the kill-ring (such as M-w, C-w, and C-k) also use the clipboard---not the primary selection. **** The "Copy", "Cut", and "Paste" items in the "Edit" menu are now exactly equivalent to, respectively M-w, C-w, and C-y. **** Note that on MS-Windows, x-select-enable-clipboard' was already non-nil by default, as Windows does not support the primary selection between applications. *** To return to the previous behavior, do the following: **** Change mouse-drag-copy-region' to t. **** Change x-select-enable-primary' to t (on X only). **** Change x-select-enable-clipboard' to nil. **** Bind mouse-yank-at-click' to mouse-2.  Chong Yidong committed Jul 14, 2010 356   Jan Djärv committed Sep 02, 2010 357 358 *** Support for X cut buffers has been removed.  Jari Aalto committed Dec 15, 2010 359 360 361 362 ** New command rectangle-number-lines', bound to C-x r N', numbers the lines in the current rectangle. With an prefix argument, this prompts for a number to count from and for a format string.  Michael Albinus committed Mar 14, 2011 363 364 365 366 ** The command shell prompts for the shell path name, when the default directory is a remote file name and neither environment variable $ESHELL nor variable explicit-shell-file-name' is set.  Richard M. Stallman committed May 14, 2005 367   Glenn Morris committed Mar 10, 2010 368 * Changes in Specialized Modes and Packages in Emacs 24.1  Eli Zaretskii committed Aug 22, 2001 369   Stefan Monnier committed Jan 28, 2011 370 371 372 ** The compile.el mode can be used without font-lock-mode. compilation-parse-errors-function' is now obsolete.  Jari Aalto committed Jan 22, 2011 373 374 ** The Landmark game is now invoked with landmark', not lm'.  Stefan Monnier committed Jan 11, 2011 375 ** Prolog mode has been completely revamped, with lots of additional  Glenn Morris committed Feb 22, 2011 376 functionality such as more intelligent indentation, electricity, support for  Stefan Monnier committed Jan 11, 2011 377 378 more variants, including Mercury, and a lot more.  Stefan Monnier committed Nov 12, 2010 379 380 381 ** shell-mode can track your cwd by reading it from your prompt. Just set shell-dir-cookie-re to an appropriate regexp.  Stefan Monnier committed Nov 11, 2010 382 383 ** Modula-2 mode provides auto-indentation.  Stefan Monnier committed Sep 18, 2010 384 385 ** latex-electric-env-pair-mode keeps \begin..\end matched on the fly.  Glenn Morris committed Oct 07, 2010 386 ** FIXME: xdg-open for browse-url and reportbug, 2010/08.  Glenn Morris committed Aug 17, 2010 387   Juri Linkov committed Apr 19, 2010 388 389 ** Archive Mode has basic support to browse 7z archives.  390 ** browse-url has gotten a new variable that is used for mailto: URLs,  Juanma Barranquero committed Mar 19, 2011 391 browse-url-mailto-function', which defaults to browse-url-mail'.  392   Glenn Morris committed Feb 22, 2011 393 394 395 396 397 398 ** Directory local variables can apply to file-less buffers, in certain modes (eg dired, vc-dir, log-edit). For example, adding "(diff-mode . ((mode . whitespace)))" to your .dir-locals.el file, will turn on whitespace-mode' for *vc-diff* buffers. Modes should call hack-dir-local-variables-non-file-buffer' to support this.  Glenn Morris committed Feb 28, 2011 399 400 401 402 403 +++ ** You can prevent directory local variables from applying to subdirectories. Add an element (subdirs . nil) to the alist portion of any variables settings to indicate said section should not be applied to subdirectories.  Vivek Dasmohapatra committed Aug 14, 2010 404 405 406 407 408 409 410 411 ** ERC changes *** New vars erc-autojoin-timing' and erc-autojoin-delay'. If the value of erc-autojoin-timing' is 'ident, ERC autojoins after a successful NickServ identification, or after erc-autojoin-delay' seconds. The default value, 'ident, means to autojoin immediately after connecting.  Lars Magne Ingebrigtsen committed Nov 05, 2010 412 413 414 415 416 *** New variable erc-coding-system-precedence': If we use undecided' as the server coding system, this variable will then be consulted. The default is to decode strings that can be decoded as utf-8 as utf-8, and do the normal undecided' decoding for the rest.  Chong Yidong committed Dec 16, 2010 417 418 419 420 421 422 ** Eshell changes *** The default value of eshell-directory-name is a directory named "eshell" in user-emacs-directory'.

The order in which they appear is the order in which they are prompted. The tokens symbols can be replaced by a sublist starting with the token and followed by a plist which control the prompting for values. The tokens user', database', and server' each can take a property of :default which specifies the value to be used if no value is entered. The database', server', and port' tokens handle the :completion property which restricts the entry to either one of the values in the list or to one of the values returned by the function provided as the property value. The database' and server' tokens also accept the :file property whose value is a regexp to identify useful file names. (user :default DEF) (database :default DEF :file FILEPAT :completion COMPLETE) (server :default DEF :file FILEPAT :completion COMPLETE) The FILEPAT when :file is specified is a regexp that will match valid file names (without the directory portion). Generally these strings will be of the form ".+\.SUF" where SUF is the desired file suffix. When :completion is specified, the COMPLETE corresponds to the PREDICATE argument to the completing-read' function (a list of possible values or a function returning such a list).

An alist for recording different username, database and server values. If there are multiple databases that you connect to the parameters needed can be stored in this alist. For example, the following might be set in the user's init.el: (setq sql-connection-alist '((dev (sql-product 'sqlite) (sql-database "/home/mmaug/dev.db")) (prd (sql-product 'oracle) (sql-user "mmaug") (sql-database "iprd2a")))) This defines two connections named "dev" and "prd". *** Added sql-connect' to use predefined connections. Sets the login parameters based on the values in the sql-connection-alist' and start a SQL interactive session. Any values specified in the connection will not be prompted for. In the example above, if the user were to invoke M-x sql-connect, they would be prompted for the connection. The user can respond with either "dev" or "prd". The "dev" connection would connect to the SQLite database without prompting; the "prd" connection would prompt for the users password and then connect to the Oracle database.
