| 25 | * Installation Changes in Emacs 24.1 |
| 26 | |
| 27 | --- |
| 28 | ** Emacs can be compiled with Gtk+ 3.0 if you pass --with-x-toolkit=gtk3 |
| 29 | to configure. Note that other libraries used by Emacs, RSVG and GConf, |
| 30 | also depend on Gtk+. You can disable them with --without-rsvg and |
| 31 | --without-gconf. |
| 32 | |
| 33 | --- |
| 34 | ** Emacs can be compiled with GnuTLS support. |
| 35 | This happens by default if a suitably recent version of the library is |
| 36 | found at build time. To prevent this, use the configure option |
| 37 | `--without-gnutls'. See below for GnuTLS features. |
| 38 | |
| 39 | --- |
| 40 | ** Emacs can be compiled with SELinux support. |
| 41 | This happens by default if a suitably recent version of the library is |
| 42 | found at build time. To prevent this, use the configure option |
| 43 | `--without-selinux'. See below for SELinux features. |
| 44 | |
| 45 | --- |
| 46 | ** Emacs can be compiled with ImageMagick support. |
| 47 | This happens by default if a suitably recent version of the library is |
| 48 | found at build time. To prevent this, use the configure option |
| 49 | `--without-imagemagick'. See below for ImageMagick features. |
| 50 | This feature is not available for the Nextstep or MS ports. |
| 51 | |
| 52 | --- |
| 53 | ** Emacs can be compiled with libxml2 support. |
| 54 | This happens by default if a suitably recent version of the library is |
| 55 | found at build time. To prevent this, use the configure option |
| 56 | `--without-xml2'. See below for libxml2 features. |
| 57 | |
| 58 | --- |
| 59 | ** There is a new configure option --with-wide-int. |
| 60 | With it, Emacs integers typically have 62 bits, even on 32-bit machines. |
| 61 | On 32-bit hosts, this raises the limit on buffer sizes from about 512 MiB |
| 62 | to about 2 GiB. |
| 63 | |
| 64 | --- |
| 65 | ** By default, the installed Info and man pages are compressed. |
| 66 | You can disable this by configuring --without-compress-info. |
| 67 | |
| 68 | --- |
| 69 | ** There are new configure options: |
| 70 | --with-mmdf, --with-mail-unlink, --with-mailhost. |
| 71 | These provide no new functionality, they just remove the need to edit |
| 72 | lib-src/Makefile by hand in order to use the associated features. |
| 73 | |
| 74 | --- |
| 75 | ** There is a new configure option --enable-use-lisp-union-type. |
| 76 | This is only useful for Emacs developers to debug certain types of bugs. |
| 77 | This is not a new feature; only the configure flag is new. |
| 78 | |
| 79 | --- |
| 80 | ** The standalone programs digest-doc and sorted-doc are removed. |
| 81 | Emacs now uses Lisp commands `doc-file-to-man' and `doc-file-to-info'. |
| 82 | |
| 83 | --- |
| 84 | ** The standalone program `fakemail' is removed. |
| 85 | If you need it, feedmail.el provides a superset of the functionality. |
| 86 | |
| 87 | \f |
| 88 | * Startup Changes in Emacs 24.1 |
| 89 | |
| 90 | --- |
| 91 | ** The --unibyte, --multibyte, --no-multibyte, and --no-unibyte |
| 92 | command line arguments, and the EMACS_UNIBYTE environment variable, no |
| 93 | longer have any effect. (They were declared obsolete in Emacs 23.) |
| 94 | |
| 95 | +++ |
| 96 | ** New command line option `--no-site-lisp' removes site-lisp directories |
| 97 | from load-path. -Q now implies this. This option does not affect the |
| 98 | EMACSLOADPATH environment variable (and hence has no effect for |
| 99 | Nextstep builds.) |
| 100 | |
| 101 | \f |
| 102 | * Changes in Emacs 24.1 |
| 103 | |
| 104 | +++ |
| 105 | ** auto-mode-case-fold is now enabled by default. |
| 106 | |
| 107 | ** Completion |
| 108 | |
| 109 | *** shell-mode uses pcomplete rules, with the standard completion UI. |
| 110 | +++ |
| 111 | *** Many packages have been changed to use `completion-at-point' |
| 112 | rather than their own completion code. |
| 113 | +++ |
| 114 | *** `completion-at-point' now handles tags and semantic completion. |
| 115 | --- |
| 116 | *** Completion in a non-minibuffer now tries to detect the end of completion |
| 117 | and pops down the *Completions* buffer accordingly. |
| 118 | +++ |
| 119 | *** Completion can cycle, depending on completion-cycle-threshold. |
| 120 | +++ |
| 121 | *** New completion style `substring'. |
| 122 | +++ |
| 123 | *** Completion style can be set per-category `completion-category-overrides'. |
| 124 | +++ |
| 125 | *** Completion of buffers now uses substring completion by default. |
| 126 | |
| 127 | ** Mail changes |
| 128 | |
| 129 | +++ |
| 130 | *** The default of `send-mail-function' is now `sendmail-query-once', |
| 131 | which asks the user (once) whether to use the smtpmail package to send |
| 132 | email, or to use the old defaults that rely on external mail |
| 133 | facilities (`sendmail-send-it' on GNU/Linux and other Unix-like |
| 134 | systems, and `mailclient-send-it' on Windows). |
| 135 | |
| 136 | --- |
| 137 | *** `compose-mail' now accepts an optional 8th arg, RETURN-ACTION, and |
| 138 | passes it to the mail user agent function. This argument specifies an |
| 139 | action for returning to the caller after finishing with the mail. |
| 140 | For example, this is used by Rmail to optionally delete a mail window. |
| 141 | |
| 142 | *** smtpmail |
| 143 | |
| 144 | **** smtpmail now uses encrypted connections (via STARTTLS) if the |
| 145 | mail server supports them. It also uses the auth-source framework for |
| 146 | getting credentials. |
| 147 | |
| 148 | **** The variable `smtpmail-auth-credentials' has been removed. |
| 149 | That variable used to have the default value "~/.authinfo", in which |
| 150 | case you won't see any difference. But if you changed it to be a list |
| 151 | of user names and passwords, that setting is now ignored; you will be |
| 152 | prompted for the user name and the password, which will then be saved |
| 153 | to ~/.authinfo. (To control where and how the credentials are stored, |
| 154 | see the auth-source manual. You may want to change the auth-source |
| 155 | preferences if you want to store the credentials encrypted, for |
| 156 | instance.) |
| 157 | |
| 158 | You can also manually copy the credentials to your ~/.authinfo file. |
| 159 | For example, if you had |
| 160 | |
| 161 | (setq smtpmail-auth-credentials |
| 162 | '(("mail.example.org" 25 "jim" "s!cret"))) |
| 163 | |
| 164 | then the equivalent line in ~/.authinfo would be |
| 165 | |
| 166 | machine mail.example.org port 25 login jim password s!cret |
| 167 | |
| 168 | **** The variable `smtpmail-starttls-credentials' has been removed. |
| 169 | |
| 170 | If you had that set, then you need to put |
| 171 | |
| 172 | machine smtp.whatever.foo port 25 key "~/.my_smtp_tls.key" cert "~/.my_smtp_tls.cert" |
| 173 | |
| 174 | in your ~/.authinfo file instead. |
| 175 | |
| 176 | *** Mail mode changes (this is the old Mail mode, not Message mode) |
| 177 | +++ |
| 178 | **** New command `mail-add-attachment' for adding MIME attachments |
| 179 | --- |
| 180 | **** The command `mail-attach-file' was renamed to `mail-insert-file'. |
| 181 | The old name is now an obsolete alias to the new name. |
| 182 | |
| 183 | +++ |
| 184 | *** You can type C-c m from M-x report-emacs-bug if you prefer, and if |
| 185 | your system supports it, to transfer your report to your desktop's |
| 186 | preferred mail client. This uses either the "xdg-email" utility, or |
| 187 | OS X's "open" command. |
| 188 | |
| 189 | ** Emacs server and client changes |
| 190 | +++ |
| 191 | *** New option `server-port' specifies the port on which the Emacs |
| 192 | server should listen. |
| 193 | +++ |
| 194 | *** New emacsclient argument -q/--quiet suppresses some status messages. |
| 195 | +++ |
| 196 | *** New emacsclient argument --frame-parameters can be used to set the |
| 197 | frame parameters of a newly-created graphical frame. |
| 198 | +++ |
| 199 | *** If emacsclient shuts down as a result of Emacs signaling an |
| 200 | error, its exit status is 1. |
| 201 | +++ |
| 202 | *** New emacsclient argument --parent-id ID. |
| 203 | This opens a client frame in parent X window ID, via XEmbed, similar |
| 204 | to the --parent-id argument to Emacs. |
| 205 | |
| 206 | ** Internationalization changes |
| 207 | |
| 208 | +++ |
| 209 | *** Emacs now supports display and editing of bidirectional text. |
| 210 | |
| 211 | Text that includes characters from right-to-left (RTL) scripts, such |
| 212 | as Arabic, Farsi, or Hebrew, is displayed in the correct visual order |
| 213 | as expected by users of those scripts. This display reordering is a |
| 214 | "Full bidirectionality" class implementation of the Unicode |
| 215 | Bidirectional Algorithm. Buffers with no RTL text should look exactly |
| 216 | the same as before. |
| 217 | |
| 218 | For more information, see the node "Bidirectional Editing" in the |
| 219 | Emacs Manual. |
| 220 | |
| 221 | +++ |
| 222 | **** New buffer-local variable `bidi-display-reordering'. |
| 223 | To disable display reordering in any given buffer, change this to nil. |
| 224 | |
| 225 | +++ |
| 226 | **** New buffer-local variable `bidi-paragraph-direction'. |
| 227 | If nil (the default), Emacs determines the base direction of each |
| 228 | paragraph from its text, as specified by the Unicode Bidirectional |
| 229 | Algorithm. |
| 230 | |
| 231 | Setting this to `right-to-left' or `left-to-right' forces a particular |
| 232 | base direction on each paragraph in the buffer. |
| 233 | |
| 234 | Paragraphs whose base direction is right-to-left are displayed |
| 235 | starting at the right margin of the window. |
| 236 | |
| 237 | +++ |
| 238 | *** Enhanced support for characters with no glyphs in available fonts. |
| 239 | If a character has no glyphs in any of the available fonts, Emacs |
| 240 | normally displays it either as a hexadecimal code in a box or as a |
| 241 | thin 1-pixel space. In addition to these two methods, Emacs can |
| 242 | display these characters as empty box, as an acronym, or not display |
| 243 | them at all. To change how these characters are displayed, customize |
| 244 | the variable `glyphless-char-display-control'. |
| 245 | |
| 246 | On character terminals, these methods are used for characters that |
| 247 | cannot be encoded by the `terminal-coding-system'. |
| 248 | |
| 249 | --- |
| 250 | *** New input methods for Farsi: farsi and farsi-translit. |
| 251 | |
| 252 | +++ |
| 253 | *** `nobreak-char-display' now also highlights Unicode hyphen chars |
| 254 | (U+2010 and U+2011). |
| 255 | |
| 256 | --- |
| 257 | *** New translation of the Emacs Tutorial in Hebrew is available. |
| 258 | Type `C-u C-h t' to choose it in case your language setup doesn't |
| 259 | automatically select it. |
| 260 | |
| 261 | ** Improved GTK integration |
| 262 | +++ |
| 263 | *** GTK scroll-bars are now placed on the right by default. |
| 264 | Use `set-scroll-bar-mode' to change this. |
| 265 | +++ |
| 266 | *** GTK tool bars can have just text, just images or images and text. |
| 267 | Customize `tool-bar-style' to choose style. On a Gnome desktop, the default |
| 268 | is taken from the desktop settings. |
| 269 | --- |
| 270 | *** GTK tool bars can be placed on the left/right or top/bottom of the frame. |
| 271 | The frame-parameter tool-bar-position controls this. It takes the values |
| 272 | top, left, right or bottom. The Options => Show/Hide menu has entries |
| 273 | for this. |
| 274 | +++ |
| 275 | *** The colors for selected text (the `region' face) are taken from |
| 276 | the GTK theme when Emacs is built with GTK. |
| 277 | +++ |
| 278 | *** Emacs uses GTK tooltips by default if built with GTK. You can turn that |
| 279 | off by customizing x-gtk-use-system-tooltips. |
| 280 | |
| 281 | +++ |
| 282 | ** New basic faces `error', `warning', `success' are available to |
| 283 | highlight strings that indicate failure, caution or successful operation. |
| 284 | |
| 285 | --- |
| 286 | ** Lucid menus and dialogs can display antialiased fonts if Emacs is built |
| 287 | with Xft. To change font, use the X resource font, for example: |
| 288 | Emacs.pane.menubar.font: Courier-12 |
| 289 | |
| 290 | +++ |
| 291 | ** On graphical displays, the mode-line no longer ends in dashes. |
| 292 | Also, the first dash (which does not indicate anything) is just |
| 293 | displayed as a space. |
| 294 | |
| 295 | +++ |
| 296 | ** Basic SELinux support has been added. |
| 297 | This requires Emacs to be linked with libselinux at build time. |
| 298 | |
| 299 | +++ |
| 300 | *** Emacs preserves the SELinux file context when backing up, and |
| 301 | optionally when copying files. To this end, copy-file has an extra |
| 302 | optional argument, and backup-buffer and friends include the SELinux |
| 303 | context in their return values. |
| 304 | |
| 305 | +++ |
| 306 | *** The new functions file-selinux-context and set-file-selinux-context |
| 307 | get and set the SELinux context of a file. |
| 308 | |
| 309 | ** Changes for exiting Emacs |
| 310 | +++ |
| 311 | *** The function kill-emacs is now run upon receipt of the signals |
| 312 | SIGTERM and SIGHUP, and upon SIGINT in batch mode. |
| 313 | +++ |
| 314 | *** kill-emacs-hook is now also run in batch mode. |
| 315 | If you have code that adds something to kill-emacs-hook, you should |
| 316 | consider if it is still appropriate to add it in the noninteractive case. |
| 317 | |
| 318 | ** Scrolling changes |
| 319 | +++ |
| 320 | *** New scrolling commands `scroll-up-command' and `scroll-down-command' |
| 321 | (bound to C-v/[next] and M-v/[prior]) do not signal errors at top/bottom |
| 322 | of buffer at first key-press (instead move to top/bottom of buffer) |
| 323 | when `scroll-error-top-bottom' is non-nil. |
| 324 | +++ |
| 325 | *** New variable `scroll-error-top-bottom' (see above). |
| 326 | +++ |
| 327 | *** New scrolling commands `scroll-up-line' and `scroll-down-line' |
| 328 | scroll a line instead of full screen. |
| 329 | +++ |
| 330 | *** New property `scroll-command' should be set on a command's symbol to |
| 331 | define it as a scroll command affected by `scroll-preserve-screen-position'. |
| 332 | +++ |
| 333 | *** If you customize `scroll-conservatively' to a value greater than 100, |
| 334 | Emacs will never recenter point in the window when it scrolls due to |
| 335 | cursor motion commands or commands that move point (e.f., `M-g M-g'). |
| 336 | Previously, you needed to use `most-positive-fixnum' as the value of |
| 337 | `scroll-conservatively' to achieve the same effect. |
| 338 | --- |
| 339 | *** ``Aggressive'' scrolling now honors the scroll margins. |
| 340 | If you customize `scroll-up-aggressively' or |
| 341 | `scroll-down-aggressively' and move point off the window, Emacs now |
| 342 | scrolls the window so as to avoid positioning point inside the scroll |
| 343 | margin. |
| 344 | |
| 345 | ** Trash changes |
| 346 | +++ |
| 347 | *** `delete-by-moving-to-trash' now only affects commands that specify |
| 348 | trashing. This avoids inadvertently trashing temporary files. |
| 349 | +++ |
| 350 | *** Calling `delete-file' or `delete-directory' with a prefix argument |
| 351 | now forces true deletion, regardless of `delete-by-moving-to-trash'. |
| 352 | |
| 353 | +++ |
| 354 | ** New option `list-colors-sort' defines the color sort order |
| 355 | for `list-colors-display'. |
| 356 | |
| 357 | ** An Emacs Lisp package manager is now included. |
| 358 | This is a convenient way to download and install additional packages, |
| 359 | from a package repository at http://elpa.gnu.org. |
| 360 | +++ |
| 361 | *** `M-x list-packages' shows a list of packages, which can be |
| 362 | selected for installation. |
| 363 | +++ |
| 364 | *** New command `describe-package', bound to `C-h P'. |
| 365 | +++ |
| 366 | *** By default, all installed packages are loaded and activated |
| 367 | automatically when Emacs starts up. To disable this, set |
| 368 | `package-enable-at-startup' to nil. To change which packages are |
| 369 | loaded, customize `package-load-list'. |
| 370 | |
| 371 | ** Custom Themes |
| 372 | +++ |
| 373 | *** `M-x customize-themes' lists Custom themes which can be enabled. |
| 374 | +++ |
| 375 | *** New option `custom-theme-load-path' is the load path for themes. |
| 376 | Emacs no longer looks for custom themes in `load-path'. The default |
| 377 | is to search in `custom-theme-directory', followed by a built-in theme |
| 378 | directory named "themes/" in `data-directory'. |
| 379 | +++ |
| 380 | *** New option `custom-safe-themes' records known-safe theme files. |
| 381 | If a theme is not in this list, Emacs queries before loading it, and |
| 382 | offers to save the theme to `custom-safe-themes' automatically. By |
| 383 | default, all themes included in Emacs are treated as safe. |
| 384 | |
| 385 | ** File- and directory-local variable changes |
| 386 | +++ |
| 387 | *** You can stop directory local vars from applying to subdirectories. |
| 388 | Add an element (subdirs . nil) to the alist portion of any variables |
| 389 | settings to indicate that the section should not apply to |
| 390 | subdirectories. |
| 391 | +++ |
| 392 | *** Directory local variables can apply to some file-less buffers. |
| 393 | Affected modes include dired, vc-dir, and log-edit. For example, |
| 394 | adding "(diff-mode . ((mode . whitespace)))" to .dir-locals.el will |
| 395 | turn on `whitespace-mode' for *vc-diff* buffers. Modes should call |
| 396 | `hack-dir-local-variables-non-file-buffer' to support this. |
| 397 | +++ |
| 398 | *** Using "mode: MINOR-MODE" to enable a minor mode is deprecated. |
| 399 | Instead, use "eval: (minor-mode 1)". |
| 400 | |
| 401 | +++ |
| 402 | *** The variable `inhibit-first-line-modes-regexps' has been renamed |
| 403 | to `inhibit-local-variables-regexps'. As the name suggests, it now |
| 404 | applies to ALL file local variables, not just -*- mode ones. |
| 405 | The associated `inhibit-first-line-modes-suffixes' has been renamed |
| 406 | in the corresponding way. |
| 407 | |
| 408 | +++ |
| 409 | ** The variable `focus-follows-mouse' now always defaults to nil. |
| 410 | |
| 411 | +++ |
| 412 | ** New primitive `secure-hash' that supports many secure hash algorithms: |
| 413 | md5, sha1, sha2, sha224, sha256, sha384, and sha512. The lisp library |
| 414 | sha1.el has been removed. The `sha1' feature is provided by default. |
| 415 | |
| 416 | ** Menu-bar changes |
| 417 | --- |
| 418 | *** `menu-bar-select-buffer-function' lets you choose another operation |
| 419 | instead of `switch-to-buffer' when selecting an item in the Buffers menu. |
| 420 | |
| 421 | ** Window changes |
| 422 | |
| 423 | +++ |
| 424 | *** Resizing an Emacs frame now preserves proportional window sizes, |
| 425 | modulo restrictions like window minimum sizes and fixed-size windows. |
| 426 | |
| 427 | *** The behavior of `display-buffer' is now customizable in detail. |
| 428 | +++ |
| 429 | **** New option `display-buffer-base-action' specifies a list of |
| 430 | user-determined display "actions" (functions and optional arguments |
| 431 | for choosing the displaying window). |
| 432 | |
| 433 | This takes precedence over the default display action, which is |
| 434 | specified by `display-buffer-fallback-action'. |
| 435 | |
| 436 | +++ |
| 437 | **** New option `display-buffer-alist' maps buffer name regexps to |
| 438 | display actions, taking precedence over `display-buffer-base-action'. |
| 439 | |
| 440 | +++ |
| 441 | *** New option `window-combination-limit'. |
| 442 | The new option `window-combination-limit' allows to return the space |
| 443 | obtained for resizing or creating a window more reliably to the window |
| 444 | from which such space was obtained. |
| 445 | |
| 446 | +++ |
| 447 | *** New option `window-combination-resize'. |
| 448 | The new option `window-combination-resize' allows to split a window that |
| 449 | otherwise cannot be split because it's too small by stealing space from |
| 450 | other windows in the same combination. Subsequent resizing or deletion |
| 451 | of the window will resize all windows in the same combination as well. |
| 452 | |
| 453 | +++ |
| 454 | *** New commands `maximize-window' and `minimize-window'. |
| 455 | These maximize and minimize the size of a window within its frame. |
| 456 | |
| 457 | +++ |
| 458 | *** New commands `switch-to-prev-buffer' and `switch-to-next-buffer'. |
| 459 | These functions allow to navigate through the live buffers that have |
| 460 | been shown in a specific window. |
| 461 | |
| 462 | +++ |
| 463 | ** The inactive minibuffer has its own major mode `minibuffer-inactive-mode'. |
| 464 | This is handy for minibuffer-only frames, and is also used for the feature |
| 465 | where mouse-1 pops up *Messages*"', which can now easily be changed. |

| 468 | * Editing Changes in Emacs 24.1 |
| 469 | |
| 470 | ** Search changes |
| 471 | +++ |
| 472 | *** C-y in Isearch is now bound to isearch-yank-kill, instead of |
| 473 | isearch-yank-line. |
| 474 | +++ |
| 475 | *** M-y in Isearch is now bound to isearch-yank-pop, instead of |
| 476 | isearch-yank-kill. |
| 477 | +++ |
| 478 | *** M-s C-e in Isearch is now bound to isearch-yank-line. |
| 479 | |
| 480 | +++ |
| 481 | ** New commands `count-words-region' and `count-words'. |
| 482 | |
| 483 | *** `count-lines-region' is now an alias for `count-words-region', |
| 484 | bound to M-=, which shows the number of lines, words, and characters. |
| 485 | |
| 486 | +++ |
| 487 | ** The default value of `backup-by-copying-when-mismatch' is now t. |
| 488 | |
| 489 | +++ |
| 490 | ** The command `just-one-space' (M-SPC), if given a negative argument, |
| 491 | also deletes newlines around point. |
| 492 | |
| 493 | ** Deletion changes |
| 494 | +++ |
| 495 | *** New option `delete-active-region'. |
| 496 | If non-nil, [delete] and DEL delete the region if it is active and no |
| 497 | prefix argument is given. If set to `kill', these commands kill |
| 498 | instead. |
| 499 | +++ |
| 500 | *** New command `delete-forward-char', bound to [delete]. |
| 501 | This is meant for interactive use, and obeys `delete-active-region'. |
| 502 | The command `delete-char' does not obey `delete-active-region'. |
| 503 | --- |
| 504 | *** `delete-backward-char' is now a Lisp function. |
| 505 | Apart from obeying `delete-active-region', its behavior is unchanged. |
| 506 | However, the byte compiler now warns if it is called from Lisp; you |
| 507 | should use delete-char with a negative argument instead. |
| 508 | --- |
| 509 | *** The option `mouse-region-delete-keys' has been deleted. |
| 510 | |
| 511 | ** Selection changes. |
| 512 | |
| 513 | The default handling of clipboard and primary selections was changed |
| 514 | to conform with modern X applications. In short, most commands for |
| 515 | killing and yanking text now use the clipboard, while mouse commands |
| 516 | use the primary selection. |
| 517 | |
| 518 | In the following, we provide a list of these changes, followed by a |
| 519 | list of steps to get the old behavior back if you prefer that. |
| 520 | |
| 521 | +++ |
| 522 | *** `select-active-regions' now defaults to t. |
| 523 | Merely selecting text (e.g. with drag-mouse-1) no longer puts it in |
| 524 | the kill ring. The selected text is put in the primary selection, if |
| 525 | the system possesses a separate primary selection facility (e.g. X). |
| 526 | |
| 527 | +++ |
| 528 | **** `select-active-regions' also accepts a new value, `only'. |
| 529 | This means to only set the primary selection for temporarily active |
| 530 | regions (usually made by mouse-dragging or shift-selection); |
| 531 | "ordinary" active regions, such as those made with C-SPC followed by |
| 532 | point motion, do not alter the primary selection. |
| 533 | |
| 534 | --- |
| 535 | **** `mouse-drag-copy-region' now defaults to nil. |
| 536 | |
| 537 | +++ |
| 538 | *** mouse-2 is now bound to `mouse-yank-primary'. |
| 539 | This pastes from the primary selection, ignoring the kill-ring. |
| 540 | Previously, mouse-2 was bound to `mouse-yank-at-click'. |
| 541 | |
| 542 | +++ |
| 543 | *** `x-select-enable-clipboard' now defaults to t on all platforms. |
| 544 | +++ |
| 545 | *** `x-select-enable-primary' now defaults to nil. |
| 546 | Thus, commands that kill text or copy it to the kill-ring (such as |
| 547 | M-w, C-w, and C-k) also use the clipboard---not the primary selection. |
| 548 | |
| 549 | --- |
| 550 | **** The "Copy", "Cut", and "Paste" items in the "Edit" menu are now |
| 551 | exactly equivalent to, respectively M-w, C-w, and C-y. |
| 552 | |
| 553 | --- |
| 554 | **** Note that on MS-Windows, `x-select-enable-clipboard' was already |
| 555 | non-nil by default, as Windows does not support the primary selection |
| 556 | between applications. |
| 557 | |
| 558 | --- |
| 559 | *** To return to the previous behavior, do the following: |
| 560 | **** Change `select-active-regions' to nil. |
| 561 | **** Change `mouse-drag-copy-region' to t. |
| 562 | **** Change `x-select-enable-primary' to t (on X only). |
| 563 | **** Change `x-select-enable-clipboard' to nil. |
| 564 | **** Bind `mouse-yank-at-click' to mouse-2. |
| 565 | |
| 566 | +++ |
| 567 | *** Support for X cut buffers has been removed. |
| 568 | |
| 569 | *** X clipboard managers are now supported. |
| 570 | To inhibit this, change `x-select-enable-clipboard-manager' to nil. |
| 571 | |
| 572 | +++ |
| 573 | ** New command `rectangle-number-lines', bound to `C-x r N', numbers |
| 574 | the lines in the current rectangle. With a prefix argument, this |
| 575 | prompts for a number to count from and for a format string. |
| 576 | |
| 577 | +++ |
| 578 | ** The default value of redisplay-dont-pause is now t |
| 579 | This makes Emacs feel more responsive to editing commands that arrive |
| 580 | at high rate, e.g. if you lean on some key, because stopping redisplay |
| 581 | in the middle (when this variable is nil) forces more expensive |
| 582 | updates later on, and Emacs appears to be unable to keep up. |
| 583 | |
| 584 | +++ |
| 585 | ** The behavior of <TAB> for active regions in Text mode has changed. |
| 586 | In Text and related modes, typing <TAB> (`indent-for-tab-command') |
| 587 | when the region is active causes Emacs to indent all the lines in the |
| 588 | region, aligning them with the line previous to the first line in the |
| 589 | region (or with the left margin if there is no previous line). |
| 590 | |
| 591 | \f |
| 592 | * Changes in Specialized Modes and Packages in Emacs 24.1 |
| 593 | |
| 594 | +++ |
| 595 | ** Archive Mode has basic support for browsing and updating 7z archives. |
| 596 | |
| 597 | ** BibTeX mode |
| 598 | --- |
| 599 | *** BibTeX mode now supports biblatex. |
| 600 | Use the variable bibtex-dialect to select different BibTeX dialects. |
| 601 | bibtex-entry-field-alist is now an obsolete alias forbibtex-BibTeX-entry-alist. |
| 602 | --- |
| 603 | *** New command `bibtex-search-entries' bound to C-c C-a. |
| 604 | --- |
| 605 | *** New `bibtex-entry-format' option `sort-fields', disabled by default. |
| 606 | --- |
| 607 | *** New variable `bibtex-search-entry-globally'. |
| 608 | |
| 609 | ** Calendar, Diary, and Appt |
| 610 | |
| 611 | +++ |
| 612 | *** Diary entries can contain non-printing `comments'. |
| 613 | See the variable `diary-comment-start'. |
| 614 | |
| 615 | +++ |
| 616 | *** Appointments can specify their individual warning times. |
| 617 | See the variable `appt-warning-time-regexp'. |
| 618 | |
| 619 | --- |
| 620 | *** The function specified by `appt-disp-window-function' may be passed |
| 621 | lists of arguments if multiple appointments are due at similar times. |
| 622 | If you are using a custom function for this, you should update it. |
| 623 | |
| 624 | +++ |
| 625 | *** New function `diary-hebrew-birthday'. |
| 626 | |
| 627 | --- |
| 628 | *** Elements of `calendar-day-abbrev-array' and `calendar-month-abbrev-array' |
| 629 | may no longer be nil, but must all be strings. |
| 630 | |
| 631 | --- |
| 632 | *** The obsolete (since Emacs 22.1) method of enabling the appt package |
| 633 | by adding appt-make-list to diary-hook has been removed. Use appt-activate. |
| 634 | |
| 635 | --- |
| 636 | *** Some appt variables (obsolete since Emacs 22.1) have been removed: |
| 637 | appt-issue-message (use the function appt-activate) |
| 638 | appt-visible/appt-msg-window (use the variable appt-display-format) |
| 639 | |
| 640 | --- |
| 641 | *** Some diary function aliases (obsolete since Emacs 22.1) have been removed: |
| 642 | view-diary-entries, list-diary-entries, show-all-diary-entries |
| 643 | |
| 644 | ** Browse-url |
| 645 | |
| 646 | +++ |
| 647 | *** New option `browse-url-mailto-function' specifies how to handle "mailto:"s. |
| 648 | |
| 649 | --- |
| 650 | *** The default browser used by the package is now the "xdg-open" program, |
| 651 | on platforms that support it. This calls your desktop's preferred browser. |
| 652 | |
| 653 | +++ |
| 654 | ** New CC Mode feature to "guess" the style in an existing buffer. |
| 655 | The main entry is M-x c-guess. |
| 656 | |
| 657 | ** comint and modes derived from it use the generic completion code. |
| 658 | |
| 659 | ** Compilation mode |
| 660 | --- |
| 661 | *** Compilation mode can be used without font-lock-mode. |
| 662 | `compilation-parse-errors-function' is now obsolete. |
| 663 | |
| 664 | --- |
| 665 | *** New variable `compilation-filter-start', bound while |
| 666 | compilation-filter-hook runs. It records the start position of the |
| 667 | text inserted by compilation-filter. |
| 668 | |
| 669 | --- |
| 670 | *** `compilation-error-screen-columns' and `compilation-first-column' |
| 671 | are obeyed in the editing buffer. So programming language modes can |
| 672 | set them, whereas previously only the value in the *compilation* buffer |
| 673 | was used. |
| 674 | |
| 675 | ** Customize |
| 676 | |
| 677 | +++ |
| 678 | *** Customize buffers now contain a search field. |
| 679 | The search is performed using `customize-apropos'. |
| 680 | To turn off the search field, set custom-search-field to nil. |
| 681 | |
| 682 | +++ |
| 683 | *** Custom options now start out hidden if at their default values. |
| 684 | Use the arrow to the left of the option name to toggle visibility. |
| 685 | |
| 686 | --- |
| 687 | *** custom-buffer-sort-alphabetically now defaults to t. |
| 688 | |
| 689 | +++ |
| 690 | *** The color widget now has a "Choose" button, which allows you to |
| 691 | choose a color via list-colors-display. |
| 692 | |
| 693 | ** D-Bus |
| 694 | |
| 695 | *** It is now possible to access buses other than the default system |
| 696 | or session bus. |
| 697 | |
| 698 | *** The dbus-register-method and dbus-register-property functions |
| 699 | optionally do not register names. |
| 700 | |
| 701 | *** The new function dbus-register-service registers a known service name |
| 702 | on a D-Bus without simultaneously registering a property or a method. |
| 703 | |
| 704 | ** Dired-x |
| 705 | --- |
| 706 | *** dired-jump and dired-jump-other-window called with a prefix argument |
| 707 | read a file name from the minibuffer instead of using buffer-file-name. |
| 708 | |
| 709 | +++ |
| 710 | *** The `dired local variables' feature provided by Dired-x is obsolete. |
| 711 | The standard directory local variables feature replaces it. |
| 712 | |
| 713 | ** ERC changes |
| 714 | |
| 715 | --- |
| 716 | *** New options `erc-autojoin-timing' and `erc-autojoin-delay', |
| 717 | controlling attempts to autojoin a channel. |
| 718 | |
| 719 | *** New variable `erc-coding-system-precedence': If we use `undecided' |
| 720 | as the server coding system, this variable will then be consulted. |
| 721 | The default is to decode strings that can be decoded as utf-8 as |
| 722 | utf-8, and do the normal `undecided' decoding for the rest. |
| 723 | |
| 724 | ** Eshell changes |
| 725 | |
| 726 | --- |
| 727 | *** The default value of `eshell-directory-name' has changed |
| 728 | to be an "eshell" directory in `user-emacs-directory'. |
| 729 | The old "~/.eshell/" directory is still used if it exists, though. |
| 730 | |
| 731 | ** gdb-mi |
| 732 | +++ |
| 733 | *** The GDB User Interface has been migrated to GDB Machine Interface. |
| 734 | It now supports multithread non-stop debugging and simultaneous |
| 735 | debugging of several threads. |
| 736 | |
| 737 | ** Image mode |
| 738 | |
| 739 | +++ |
| 740 | *** RET (`image-toggle-animation') toggles animation, if applicable. |
| 741 | Animation plays once, unless the option `image-animate-loop' is non-nil. |
| 742 | |
| 743 | ** Info |
| 744 | |
| 745 | +++ |
| 746 | *** New command `info-display-manual' displays a named Info manual. |
| 747 | If that manual is already visited in some Info buffer, it displays |
| 748 | that buffer. (This is handy if you have many manuals in many *info* |
| 749 | buffers, and don't remember the name of the buffer visiting the manual |
| 750 | you want to consult.) Otherwise, it loads and displays the manual. |
| 751 | |
| 752 | +++ |
| 753 | *** `e' is now bound to `end-of-buffer' rather than to `Info-edit'. |
| 754 | This is for compatibility with the stand-alone Info reader program, |
| 755 | and also because `Info-edit' is a rarely used command that is disabled |
| 756 | by default. |
| 757 | |
| 758 | +++ |
| 759 | ** MH-E has been upgraded to MH-E version 8.3.1. |
| 760 | See MH-E-NEWS for details. |
| 761 | |
| 762 | --- |
| 763 | ** Modula-2 mode provides auto-indentation. |
| 764 | |
| 765 | --- |
| 766 | ** mpc.el: Can use pseudo tags of the form tag1|tag2 as a union of two tags. |
| 767 | |
| 768 | --- |
| 769 | ** Prolog mode has been completely revamped, with lots of additional |
| 770 | functionality such as more intelligent indentation, electricity, support for |
| 771 | more variants, including Mercury, and a lot more. |
| 772 | |
| 773 | ** Rmail |
| 774 | |
| 775 | +++ |
| 776 | *** The command `rmail-epa-decrypt' decrypts OpenPGP data |
| 777 | in the Rmail incoming message. |
| 778 | |
| 779 | --- |
| 780 | *** The variable `rmail-message-filter' no longer has any effect. |
| 781 | This change was made in Emacs 23.1 but was not advertised at the time. |
| 782 | Try using `rmail-show-message-hook' instead. |
| 783 | |
| 784 | ** Shell mode |
| 785 | +++ |
| 786 | *** Shell mode uses pcomplete rules, with the standard completion UI. |
| 787 | +++ |
| 788 | *** The `shell' command prompts for the shell path name if the default |
| 789 | directory is a remote file name and neither the environment variable |
| 790 | $ESHELL nor the variable `explicit-shell-file-name' is set. |
| 791 | |
| 792 | --- |
| 793 | ** SQL mode |
| 794 | |
| 795 | --- |
| 796 | *** New options `sql-port', `sql-connection-alist', `sql-send-terminator', |
| 797 | and `sql-oracle-scan-on'. |
| 798 | |
| 799 | --- |
| 800 | *** New custom variables control prompting for login parameters. |
| 801 | Each supported product has a custom variable `sql-*-login-params', |
| 802 | which is a list of the parameters to be prompted for before a |
| 803 | connection is established. |
| 804 | |
| 805 | --- |
| 806 | *** The command `sql-product-interactive' now takes a prefix argument, |
| 807 | which causes it to prompt for an SQL product. |
| 808 | |
| 809 | --- |
| 810 | *** Product-specific SQL interactive commands now take prefix arguments. |
| 811 | These commands (`sql-sqlite', `sql-postgres', `sql-mysql', etc.), |
| 812 | given a prefix argument, prompt for a name for the SQL interactive |
| 813 | buffer. This reduces the need for calling `sql-rename-buffer'. |
| 814 | |
| 815 | --- |
| 816 | *** SQL interactive modes suppress command continuation prompts, and |
| 817 | replace tabs with spaces. The first change impacts multiple line SQL |
| 818 | statements entered with C-j between each line, statements yanked into |
| 819 | the buffer and statements sent with `sql-send-*' functions. The |
| 820 | second prevents the MySQL and Postgres interpreters from listing |
| 821 | object name completions when sent text via `sql-send-*' functions. |
| 822 | |
| 823 | --- |
| 824 | *** New command `sql-connect' starts a predefined SQLi session, |
| 825 | using the login parameters from `sql-connection-alist'. |
| 826 | |
| 827 | --- |
| 828 | *** New "Save Connection" menu item in SQLi buffers. |
| 829 | This gathers the login params specified for the SQLi session, if it |
| 830 | was not started by a connection, and saves them as a new connection. |
| 831 | |
| 832 | --- |
| 833 | *** New commands for listing database objects and details: |
| 834 | sql-list-all and sql-list-table. |
| 835 | |
| 836 | --- |
| 837 | *** An API for manipulating SQL product definitions has been added. |
| 838 | |
| 839 | ** TeX modes |
| 840 | |
| 841 | +++ |
| 842 | *** latex-electric-env-pair-mode keeps \begin..\end matched on the fly. |
| 843 | |
| 844 | ** Tramp |
| 845 | --- |
| 846 | *** There exists a new inline access method "ksu" (kerberized su). |
| 847 | --- |
| 848 | *** The following access methods are discontinued: "ssh1_old", |
| 849 | "ssh2_old", "scp1_old", "scp2_old", "imap", "imaps" and "fish". |
| 850 | +++ |
| 851 | *** The user option `remote-file-name-inhibit-cache' controls whether |
| 852 | remote file attributes are cached for better performance. |
| 853 | --- |
| 854 | *** The option `ange-ftp-binary-file-name-regexp' has changed its |
| 855 | default value to "". |
| 856 | --- |
| 857 | *** Handlers for file-selinux-context and set-file-selinux-context for |
| 858 | remote machines that support SELinux. |
| 859 | |
| 860 | +++ |
| 861 | ** New function, url-queue-retrieve, fetches URLs asynchronously like |
| 862 | url-retrieve does, but in parallel. |
| 863 | |
| 864 | ** VC and related modes |
| 865 | |
| 866 | +++ |
| 867 | *** Support for pulling on distributed version control systems. |
| 868 | `C-x v +' (`vc-pull') runs a "pull" operation, if it is supported |
| 869 | (currently with Bzr, Git, and Mercurial), to update the current branch |
| 870 | and working tree. A prefix argument means to prompt the user for |
| 871 | specifics, e.g. a pull location. |
| 872 | |
| 873 | --- |
| 874 | *** `vc-update' is now an alias for `vc-pull'. |
| 875 | |
| 876 | +++ |
| 877 | *** Support for merging on distributed version control systems. |
| 878 | The vc-merge command now runs a "merge" operation, if it is supported |
| 879 | (currently with Bzr, Git, and Mercurial), to merge changes from |
| 880 | another branch into the current one. It prompts for specifics, e.g. a |
| 881 | merge source. |
| 882 | |
| 883 | +++ |
| 884 | *** New option `vc-revert-show-diff' controls whether `vc-revert' |
| 885 | shows a diff while querying the user. It defaults to t. |
| 886 | |
| 887 | +++ |
| 888 | *** Log entries in some Log View buffers can be toggled to display a |
| 889 | longer description by typing RET (log-view-toggle-entry-display). |
| 890 | This is currently supported for Bzr, Git, and Mercurial (to support |
| 891 | another backend, define a `log-view-expanded-log-entry-function'). |
| 892 | In the Log View buffers made by `C-x v L' (vc-print-root-log), you can |
| 893 | use this to display the full log entry for the revision at point. |
| 894 | |
| 895 | +++ |
| 896 | *** New command `vc-ediff' allows visual comparison of two revisions |
| 897 | of a file similar to `vc-diff', but using ediff backend. |
| 898 | |
| 899 | +++ |
| 900 | *** The option `vc-initial-comment' was removed in Emacs 23.2, but |
| 901 | this was not advertised at the time. |
| 902 | |
| 903 | +++ |
| 904 | *** `vc-toggle-read-only' is an obsolete alias for `toggle-read-only'. |
| 905 | Since Emacs 23, it has done the same thing as `toggle-read-only', but |
| 906 | this was not advertised at the time. |
| 907 | |
| 908 | ** Obsolete modes |
| 909 | |
| 910 | --- |
| 911 | *** abbrevlist.el |
| 912 | |
| 913 | --- |
| 914 | *** erc-hecomplete.el (use erc-pcomplete.el instead) |
| 915 | |
| 916 | *** partial-completion-mode (complete.el) is obsolete. |
| 917 | You can get a comparable behavior with: |
| 918 | (setq completion-styles '(partial-completion initials)) |
| 919 | (setq completion-pcm-complete-word-inserts-delimiters t) |
| 920 | |
| 921 | --- |
| 922 | *** pc-mode.el is obsolete (CUA mode is much more comprehensive). |
| 923 | |
| 924 | [FIXME gnus.texi, message.texi need updating] |
| 925 | *** pgg is obsolete (use EasyPG instead) |
| 926 | |
| 927 | --- |
| 928 | *** sregex.el is obsolete, since rx.el is a strict superset. |
| 929 | |
| 930 | --- |
| 931 | *** s-region.el and pc-select.el are obsolete. |
| 932 | They are superseded by shift-select-mode, enabled by default since 23.1. |
| 933 | |
| 934 | +++ |
| 935 | *** vc-mcvs.el is obsolete (for lack of a maintainer) |
| 936 | |
| 937 | ** Miscellaneous |
| 938 | |
| 939 | +++ |
| 940 | *** The Landmark game is now invoked with `landmark', not `lm'. |

| 946 | +++ |
| 947 | *** f90.el has some support for Fortran 2008 syntax. |

| 957 | |
| 958 | +++ |
| 959 | ** Occur Edit mode applies edits made in *Occur* buffers to the |
| 960 | original buffers. It is bound to "e" in Occur mode. |

| 962 | +++ |
| 963 | ** New global minor mode electric-pair-mode. |
| 964 | When enabled, typing an open parenthesis automatically inserts the |
| 965 | matching closing one. |
| 966 | |
| 967 | +++ |
| 968 | ** New global minor mode electric-indent-mode. |
| 969 | When enabled, typing certain characters triggers reindentation. |
| 970 | Major modes wishing to use this can set electric-indent-chars or |
| 971 | electric-indent-functions. |
| 972 | |
| 973 | +++ |
| 974 | ** New global minor mode electric-layout-mode. |
| 975 | When enabled, typing certain characters automatically inserts newlines. |
| 976 | Major modes wishing to use this can set electric-layout-rules. |
| 977 | |
| 978 | +++ |
| 979 | ** tabulated-list.el provides a generic major mode for tabulated data, |
| 980 | from which other modes can be derived. |
| 981 | |
| 982 | ** pcase.el provides the ML-style pattern matching macro `pcase'. |
| 983 | |
| 984 | ** secrets.el is an implementation of the Secret Service API, an |
| 985 | interface to password managers like GNOME Keyring or KDE Wallet. The |
| 986 | Secret Service API requires D-Bus for communication. The command |
| 987 | `secrets-show-secrets' offers a buffer with a visualization of the |
| 988 | secrets. |
| 989 | |
| 990 | ** notifications.el provides an implementation of the Desktop |
| 991 | Notifications API. It requires D-Bus for communication. |
| 992 | |
| 993 | ** soap-client.el supports access to SOAP web services from Emacs. |
| 994 | soap-inspect.el is an interactive inspector for SOAP WSDL structures. |

| 997 | ** New generic mode, xmodmap-generic-mode, for xmodmap files. |
| 998 | |
| 999 | --- |
| 1000 | ** New emacs-lock.el package. |
| 1001 | (The previous version has been moved to obsolete/old-emacs-lock.el.) |
| 1002 | Now, there is a proper minor mode `emacs-lock-mode'. |
| 1003 | Protection against exiting Emacs and killing the buffer can be set |
| 1004 | separately. The mechanism for automatically turning off protection |
| 1005 | for buffers with dead inferior processes has been generalized. |

| 1008 | * Incompatible Lisp Changes in Emacs 24.1 |
| 1009 | |
| 1010 | --- |
| 1011 | ** `char-direction-table' and the associated function `char-direction' |
| 1012 | were deleted. They were buggy and inferior to the new support of |
| 1013 | bidirectional editing introduced in Emacs 24. If you need the |
| 1014 | bidirectional properties of a character, use `get-char-code-property' |
| 1015 | with the last argument `bidi-class'. |
| 1016 | |
| 1017 | +++ |
| 1018 | ** `copy-directory' now copies the source directory as a subdirectory |
| 1019 | of the target directory, if the latter is an existing directory. The |
| 1020 | new optional arg COPY-CONTENTS, if non-nil, makes the function copy |
| 1021 | the contents directly into a pre-existing target directory. |
| 1022 | |
| 1023 | +++ |
| 1024 | ** For mouse click input events in the text area, the Y pixel |
| 1025 | coordinate in the POSITION list now counts from the top of the text |
| 1026 | area, excluding any header line. Previously, it counted from the top |
| 1027 | of the header line. |
| 1028 | |
| 1029 | --- |
| 1030 | ** Support for "old-style" backquotes, which have been obsolete for |
| 1031 | more than 10 years, has been further reduced. Now a backquote not |
| 1032 | followed by a space is always treated as a "new-style" backquote. |
| 1033 | Please consider completely removing all "old-style" backquotes from |
| 1034 | your code as a matter of some urgency. If your code uses backquotes |
| 1035 | as documented in the Elisp manual, and compiles without warning, then |
| 1036 | you have nothing to do in this regard. Code not following the |
| 1037 | appropriate conventions may fail to compile. The most common cause of |
| 1038 | trouble seems to be an old-style backquote followed by a newline. |
| 1039 | |
| 1040 | --- |
| 1041 | ** view-buffer now treats special mode-class in the same way that |
| 1042 | view-file has since Emacs 22 (ie, it won't enable View mode if the |
| 1043 | major-mode is special). |
| 1044 | |
| 1045 | +++ |
| 1046 | ** Passing a nil argument to a minor mode defined by define-minor-mode |
| 1047 | now turns the mode ON unconditionally. This is so that you can write, e.g. |
| 1048 | (add-hook 'text-mode-hook 'foo-minor-mode) |
| 1049 | to enable foo-minor-mode in Text mode buffers, thus removing the need |
| 1050 | for `turn-on-foo-minor-mode' style functions. |
| 1051 | |
| 1052 | +++ |
| 1053 | ** During startup, Emacs no longer adds entries for `menu-bar-lines' |
| 1054 | and `tool-bar-lines' to `default-frame-alist' and `initial-frame-alist'. |
| 1055 | With these alist entries omitted, `make-frame' checks the value of the |
| 1056 | variable `menu-bar-mode'/`tool-bar-mode' to determine whether to create |
| 1057 | a menu-bar or tool-bar, respectively. If the alist entries are added, |
| 1058 | they override the value of `menu-bar-mode'/`tool-bar-mode'. |
| 1059 | |
| 1060 | +++ |
| 1061 | ** Regions created by mouse dragging are now normal active regions, |
| 1062 | similar to the ones created by shift-selection. In previous Emacs |
| 1063 | versions, these regions were delineated by `mouse-drag-overlay', which |
| 1064 | has now been removed. |
| 1065 | |
| 1066 | +++ |
| 1067 | ** The fourth argument of filter-buffer-substring, which says to remove |
| 1068 | text properties from the final result, has been removed. |
| 1069 | Eg simply pass the result through substring-no-properties if you need this. |

| 1111 | * Lisp changes in Emacs 24.1 |
| 1112 | |
| 1113 | +++ |
| 1114 | ** Code can now use lexical scoping by default instead of dynamic scoping. |
| 1115 | The `lexical-binding' variable lets code use lexical scoping for local |
| 1116 | variables. It is typically set via a file-local variable in the first |
| 1117 | line of the file, in which case it applies to all the code in that file. |
| 1118 | +++ |
| 1119 | *** `eval' takes a new optional argument `lexical' to choose the new lexical |
| 1120 | binding instead of the old dynamic binding mode. |
| 1121 | +++ |
| 1122 | *** Lexically scoped interpreted functions are represented with a new form |
| 1123 | of function value which looks like (closure ENV ARGS &rest BODY). |
| 1124 | |
| 1125 | *** New macro `letrec' to define recursive local functions. |
| 1126 | +++ |
| 1127 | *** New function `special-variable-p' to check whether a variable is |
| 1128 | declared as dynamically bound. |
| 1129 | |
| 1130 | +++ |
| 1131 | ** An Emacs Lisp testing tool is now included. |
| 1132 | Emacs Lisp developers can use this tool to write automated tests for |
| 1133 | their code. See the ERT info manual for details. |
| 1134 | |
| 1135 | ** Changes for bidirectional display and editing |
| 1136 | |
| 1137 | +++ |
| 1138 | *** New function `current-bidi-paragraph-direction'. |
| 1139 | This returns the actual value of base direction of the paragraph at |
| 1140 | point. |
| 1141 | |
| 1142 | +++ |
| 1143 | *** New function `bidi-string-mark-left-to-right'. |
| 1144 | Given a string containing characters from right-to-left (RTL) scripts, |
| 1145 | this function returns another string which can be safely inserted into |
| 1146 | a buffer, such that any following text will be always displayed to the |
| 1147 | right of that string. (This works by appending the Unicode |
| 1148 | "LEFT-TO-RIGHT MARK" character when the argument string might need that.) |
| 1149 | |
| 1150 | This is useful when the buffer has overall left-to-right (LTR) |
| 1151 | paragraph direction and you need to insert a string whose contents and |
| 1152 | directionality are not known in advance, without disrupting the layout |
| 1153 | of the line. |
| 1154 | |
| 1155 | ** Window changes |
| 1156 | +++ |
| 1157 | *** Window tree functions are accessible in Elisp. |
| 1158 | Functions are provided to return the parent, siblings or child windows |
| 1159 | of any window including internal windows (windows not associated with a |
| 1160 | buffer) in the window tree. |
| 1161 | +++ |
| 1162 | **** New function `window-valid-p' gives non-nil for live and internal |
| 1163 | windows. |
| 1164 | +++ |
| 1165 | **** Window manipulation can deal with internal windows. |
| 1166 | Many window handling functions like `split-window', `delete-window', or |
| 1167 | `delete-other-windows' as well as the window resizing functions can now |
| 1168 | act on any window including internal ones. |
| 1169 | +++ |
| 1170 | *** window-total-height/-width vs window-body-height/-width. |
| 1171 | The function `window-height' has been renamed to `window-total-height' |
| 1172 | and `window-width' has been renamed to `window-body-width'. The old |
| 1173 | names are provided as aliases. Two new functions `window-total-width' |
| 1174 | and `window-body-height' are provided. |
| 1175 | +++ |
| 1176 | *** Window parameters specific to window handling functions. |
| 1177 | For each window you can specify a parameter to override the default |
| 1178 | behavior of a number of functions like `split-window', `delete-window' |
| 1179 | and `delete-other-windows'. The variable `ignore-window-parameters' |
| 1180 | allows to ignore processing such parameters. |
| 1181 | +++ |
| 1182 | *** New semantics of third argument of `split-window'. |
| 1183 | The third argument of `split-window' has been renamed to SIDE and can be |
| 1184 | set to any of the values 'below, 'right, 'above, or 'left to make the |
| 1185 | new window appear on the corresponding side of the window that shall be |
| 1186 | split. Any other value of SIDE will cause `split-window' to split the |
| 1187 | window into two side-by-side windows as before. |
| 1188 | +++ |
| 1189 | *** Window resizing functions. |
| 1190 | A new standard function for resizing windows called `window-resize' has |
| 1191 | been introduced. This and all other functions for resizing windows no |
| 1192 | longer delete any windows when they become too small. |
| 1193 | +++ |
| 1194 | *** Deleting the selected window now selects the most recently selected |
| 1195 | live window on that frame instead. |
| 1196 | +++ |
| 1197 | *** `adjust-window-trailing-edge' adjustments. |
| 1198 | `adjust-window-trailing-edge' can now deal with fixed-size windows and |
| 1199 | is able to resize other windows if a window adjacent to the trailing |
| 1200 | edge cannot be shrunk any more. This makes its behavior more similar to |
| 1201 | that of Emacs 21 without compromising, however, its inability to delete |
| 1202 | windows which was introduced in Emacs 22. |
| 1203 | +++ |
| 1204 | *** Window-local buffer lists. |
| 1205 | Windows now have local buffer lists. This means that removing a buffer |
| 1206 | from display in a window will preferably show the buffer previously |
| 1207 | shown in that window with its previous window-start and window-point |
| 1208 | positions. This also means that the same buffer may be automatically |
| 1209 | shown twice even if it already appears in another window. |
| 1210 | +++ |
| 1211 | *** `switch-to-buffer' has a new optional argument FORCE-SAME-WINDOW, |
| 1212 | which if non-nil requires the buffer to be displayed in the currently |
| 1213 | selected window, signaling an error otherwise. If nil, another window |
| 1214 | can be used, e.g. if the selected one is strongly dedicated. |
| 1215 | +++ |
| 1216 | *** `split-window-vertically' and `split-window-horizontally' renamed |
| 1217 | to `split-window-below' and `split-window-right' respectively. |
| 1218 | The old names are kept as aliases. |
| 1219 | +++ |
| 1220 | *** Display actions |
| 1221 | |
| 1222 | **** The second arg to `display-buffer' and `pop-to-buffer' is now |
| 1223 | named ACTION, and takes a display action of the same form as |
| 1224 | `display-buffer-base-action' (see Changes, above). A non-nil, |
| 1225 | non-list value is treated specially, as the old meaning. |
| 1226 | |
| 1227 | **** New variable `display-buffer-overriding-action'. |
| 1228 | |
| 1229 | **** The procedure of `display-buffer' etc. to choose a window is |
| 1230 | determined by combining `display-buffer-overriding-action', |
| 1231 | `display-buffer-alist', the ACTION arg, `display-buffer-base-action', |
| 1232 | and `display-buffer-fallback-action'. The second and fourth of these |
| 1233 | are user-customizable variables. |
| 1234 | |
| 1235 | See the docstring of `display-buffer' for details. |
| 1236 | |
| 1237 | +++ |
| 1238 | *** New behavior of `quit-window'. |
| 1239 | The behavior of `quit-window' has been changed in order to restore the |
| 1240 | state before the last buffer display operation in that window. |
| 1241 | |
| 1242 | +++ |
| 1243 | *** The new option `frame-auto-hide-function' lets you choose between |
| 1244 | iconifying or deleting a frame when burying a buffer shown in a dedicated |
| 1245 | frame or quitting a window showing a buffer in a frame of its own. |
| 1246 | |
| 1247 | +++ |
| 1248 | *** New functions `window-state-get' and `window-state-put'. |
| 1249 | These functions allow to save and restore the state of an arbitrary |
| 1250 | frame or window as an Elisp object. |
| 1251 | |
| 1252 | ** Completion |
| 1253 | |
| 1254 | *** New variable completion-extra-properties used to specify extra properties |
| 1255 | of the current completion: |
| 1256 | - :annotate-function, same as the old completion-annotate-function. |
| 1257 | - :exit-function, function to call after completion took place. |
| 1258 | |
| 1259 | *** Functions on completion-at-point-functions can return any of the properties |
| 1260 | valid for completion-extra-properties. |
| 1261 | |
| 1262 | *** completion-annotate-function is obsolete. |
| 1263 | |
| 1264 | *** New `metadata' method for completion tables. The metadata thus returned |
| 1265 | can specify various details of the data returned by `all-completions': |
| 1266 | - `category' is the kind of objects returned (e.g., `buffer', `file', ...), |
| 1267 | used to select a style in completion-category-overrides. |
| 1268 | - `annotation-function' to add annotations in *Completions*. |
| 1269 | - `display-sort-function' to specify how to sort entries in *Completions*. |
| 1270 | - `cycle-sort-function' to specify how to sort entries when cycling. |
| 1271 | |
| 1272 | *** minibuffer-local-filename-must-match-map is not used any more. |
| 1273 | Instead, the bindings in minibuffer-local-filename-completion-map are |
| 1274 | combined with minibuffer-local-must-match-map. |
| 1275 | |
| 1276 | *** New variable `completing-read-function' allows overriding the |
| 1277 | behavior of `completing-read'. |
| 1278 | |
| 1279 | +++ |
| 1280 | ** `glyphless-char-display' can now distinguish between graphical and |
| 1281 | text terminal display, via a char-table entry that is a cons cell. |
| 1282 | |
| 1283 | ** `open-network-stream' can now be used to open an encrypted stream. |
| 1284 | It now accepts an optional `:type' parameter for initiating a TLS |
| 1285 | connection, directly or via STARTTLS. To do STARTTLS, additional |
| 1286 | parameters (`:end-of-command', `:success', `:capabilities-command') |
| 1287 | must also be supplied. |
| 1288 | |
| 1289 | +++ |
| 1290 | ** pre/post-command-hook are not reset to nil upon error. |
| 1291 | Instead, the offending function is removed. |
| 1292 | |
| 1293 | ** New hook types |
| 1294 | |
| 1295 | +++ |
| 1296 | *** New function `run-hook-wrapped' for running an abnormal hook by |
| 1297 | passing the hook functions as arguments to a "wrapping" function. |
| 1298 | Like `run-hook-with-args-until-success', it stops at the first |
| 1299 | non-nil return value. |
| 1300 | |
| 1301 | +++ |
| 1302 | *** New macro `with-wrapper-hook' for running an abnormal hook as a |
| 1303 | set of "wrapping" filters, similar to around advice. |
| 1304 | (A version of this macro was actually added in Emacs 23.2 but was not |
| 1305 | advertised at the time.) |
| 1306 | |
| 1307 | +++ |
| 1308 | ** The macros `condition-case-no-debug' and `with-demoted-errors' were |
| 1309 | added in Emacs 23.1, but not advertised. |
| 1310 | |
| 1311 | +++ |
| 1312 | ** The new function `server-eval-at' allows evaluation of Lisp forms on |
| 1313 | named Emacs server instances, using TCP sockets. |
| 1314 | |
| 1315 | +++ |
| 1316 | ** `call-process' and `call-process-region' allow a `(:file "file")' spec |
| 1317 | to redirect STDOUT to a file. |
| 1318 | |
| 1319 | --- |
| 1320 | ** Variable `stack-trace-on-error' removed. |
| 1321 | Also the debugger can now "continue" from an error, which means it will jump |
| 1322 | to the error handler as if the debugger had not been invoked instead of |
| 1323 | jumping all the way to the top-level. |
| 1324 | |
| 1325 | +++ |
| 1326 | ** The function format-time-string now supports the %N directive, for |
| 1327 | higher-resolution time stamps. |
| 1328 | |
| 1329 | +++ |
| 1330 | ** New function `read-char-choice' reads a restricted set of characters, |
| 1331 | discarding any inputs not inside the set. |
| 1332 | |
| 1333 | +++ |
| 1334 | ** `image-library-alist' is renamed to `dynamic-library-alist'. |
| 1335 | The variable is now used to load all kind of supported dynamic libraries, |
| 1336 | not just image libraries. The previous name is still available as an |
| 1337 | obsolete alias. |
| 1338 | |
| 1339 | ** New variable `syntax-propertize-function'. |
| 1340 | This replaces `font-lock-syntactic-keywords' which is now obsolete. |
| 1341 | This allows syntax-table properties to be set independently from font-lock: |
| 1342 | just call syntax-propertize to make sure the text is propertized. |
| 1343 | Together with this new variable come a new hook |
| 1344 | syntax-propertize-extend-region-functions, as well as two helper functions: |
| 1345 | syntax-propertize-via-font-lock to reuse old font-lock-syntactic-keywords |
| 1346 | as-is; and syntax-propertize-rules which provides a new way to specify |
| 1347 | syntactic rules. |
| 1348 | |
| 1349 | +++ |
| 1350 | ** New hook post-self-insert-hook run at the end of self-insert-command. |
| 1351 | |
| 1352 | +++ |
| 1353 | ** Syntax tables support a new "comment style c" additionally to style b. |
| 1354 | |
| 1355 | --- |
| 1356 | ** frame-local variables cannot be let-bound any more. |
| 1357 | |
| 1358 | ** Major and minor mode changes |
| 1359 | +++ |
| 1360 | *** `prog-mode' is a new major mode from which programming modes |
| 1361 | should be derived. |
| 1362 | |
| 1363 | +++ |
| 1364 | **** `prog-mode-hook' can be used to enable features for programming |
| 1365 | modes, e.g. (add-hook 'prog-mode-hook 'flyspell-prog-mode) to enable |
| 1366 | on-the-fly spell checking for comments and strings. |
| 1367 | |
| 1368 | +++ |
| 1369 | *** New hook `change-major-mode-after-body-hook', run by |
| 1370 | `run-mode-hooks' just before any other mode hooks. |
| 1371 | |
| 1372 | +++ |
| 1373 | *** Enabled globalized minor modes can be disabled in specific major modes. |
| 1374 | If the global mode is global-FOO-mode, then run (FOO-mode -1) in the |
| 1375 | major mode's hook, where FOO-mode toggles the mode on a per-buffer basis. |
| 1376 | |
| 1377 | +++ |
| 1378 | *** `define-minor-mode' accepts a new keyword :variable. |
| 1379 | |
| 1380 | +++ |
| 1381 | ** `delete-file' and `delete-directory' now accept optional arg TRASH. |
| 1382 | Trashing is performed if TRASH and `delete-by-moving-to-trash' are |
| 1383 | both non-nil. Interactively, TRASH defaults to t, unless a prefix |
| 1384 | argument is supplied (see Trash changes, above). |
| 1385 | |
| 1386 | --- |
| 1387 | ** `facemenu-read-color' is now an alias for `read-color'. |
| 1388 | |
| 1389 | +++ |
| 1390 | ** The command `read-color' now requires a match for a color name |
| 1391 | or RGB triplet, instead of signaling an error if the user provides |
| 1392 | invalid input. |
| 1393 | |
| 1394 | +++ |
| 1395 | ** Tool-bars can display separators. |
| 1396 | Tool-bar separators are handled like menu separators in menu-bar maps, |
| 1397 | i.e. via menu entries of the form `(menu-item "--")'. |
| 1398 | |
| 1399 | ** Image API |
| 1400 | |
| 1401 | +++ |
| 1402 | *** Animated images support (currently animated gifs only). |
| 1403 | |
| 1404 | +++ |
| 1405 | **** `image-animated-p' returns non-nil if an image can be animated. |
| 1406 | |
| 1407 | +++ |
| 1408 | **** `image-animate' animates a supplied image spec. |
| 1409 | |
| 1410 | +++ |
| 1411 | **** `image-animate-timer' returns the timer object for an image that |
| 1412 | is being animated. |
| 1413 | |
| 1414 | --- |
| 1415 | *** `image-extension-data' has been renamed to `image-metadata'. |
| 1416 | The old name is an obsolete alias to the new one. |
| 1417 | |
| 1418 | +++ |
| 1419 | *** Image mode can view any image type that ImageMagick supports. |
| 1420 | This requires Emacs to be built with ImageMagick support. |
| 1421 | Then the function `imagemagick-types' returns a list of image file |
| 1422 | extensions that your installation of ImageMagick supports. The |
| 1423 | function `imagemagick-register-types' enables ImageMagick support for |
| 1424 | these image types, minus those listed in `imagemagick-types-inhibit'. |
| 1425 | Visiting one of these file types will then use Image mode. |
| 1426 | |
| 1427 | --- |
| 1428 | *** New commands to resize and rotate images in Image mode. |
| 1429 | These require Emacs to be built with ImageMagick support. |
| 1430 | image-transform-fit-to-height, image-transform-fit-to-width, |
| 1431 | image-transform-set-rotation, image-transform-set-scale. |
| 1432 | |
| 1433 | ** XML and HTML parsing |
| 1434 | If Emacs is compiled with libxml2 support, there are two new functions: |
| 1435 | `libxml-parse-html-region' (which parses "real world" HTML) and |
| 1436 | `libxml-parse-xml-region' (which parses XML). Both return an Emacs |
| 1437 | Lisp parse tree. |
| 1438 | |
| 1439 | FIXME: These should be front-ended by xml.el. |
| 1440 | |
| 1441 | ** GnuTLS |
| 1442 | |
| 1443 | *** New library `gnutls.el'. |
| 1444 | This requires Emacs to have been built with GnuTLS support. |
| 1445 | The main functions are `open-gnutls-stream' and `gnutls-negotiate'. |
| 1446 | It's easiest to use these functions through `open-network-stream' |
| 1447 | because it can upgrade connections through STARTTLS opportunistically |
| 1448 | or use plain SSL, depending on your needs. For debugging, set |
| 1449 | `gnutls-log-level' greater than 0. |
| 1450 | |
| 1451 | ** Isearch |
| 1452 | |
| 1453 | --- |
| 1454 | *** New hook `isearch-update-post-hook' that runs in `isearch-update'. |
| 1455 | |
| 1456 | +++ |
| 1457 | ** Progress reporters can now "spin". |
| 1458 | The MIN-VALUE and MAX-VALUE arguments of `make-progress-reporter' can |
| 1459 | now be nil, or omitted. This makes a "non-numeric" reporter. Each |
| 1460 | time you call `progress-reporter-update' on that progress reporter, |
| 1461 | with a nil or omitted VALUE argument, the reporter message is |
| 1462 | displayed with a "spinning bar". |
| 1463 | |
| 1464 | +++ |
| 1465 | ** New variable `revert-buffer-in-progress-p' is true while a buffer is |
| 1466 | being reverted, even if the buffer has a local `revert-buffer-function'. |
| 1467 | |
| 1468 | --- |
| 1469 | ** New variables `delayed-warnings-list' and `delayed-warnings-hook'. |
| 1470 | If delayed-warnings-list is non-nil, the command loop calls |
| 1471 | delayed-warnings-hook after post-command-hook. At present, this is |
| 1472 | only used by Emacs on some platforms to display warnings during |
| 1473 | startup, which might otherwise not be noticed. This uses the functions |
| 1474 | display-delayed-warnings and collapse-delayed-warnings. |
| 1475 | |
| 1476 | |
| 1477 | +++ |
| 1478 | ** `set-auto-mode' now respects mode: local variables at the end of files, |
| 1479 | as well as those in the -*- line. |
| 1480 | |
| 1481 | --- |
| 1482 | ** rx.el has a new `group-n' construct for explicitly numbered groups. |
| 1483 | |
| 1484 | +++ |
| 1485 | ** New function `make-composed-keymap' that constructs a new keymap |
| 1486 | from multiple input maps. You can use this to make a keymap that |
| 1487 | inherits from multiple maps, eg: |
| 1488 | (set-keymap-parent newmap (make-composed-keymap othermap parent)) |
| 1489 | |
| 1490 | +++ |
| 1491 | ** Set `debug-on-event' to make Emacs enter the debugger e.g. on receipt |
| 1492 | of SIGUSR1. This can be useful when `inhibit-quit' is set. |
| 1493 | |
| 1494 | +++ |
| 1495 | ** New reader macro ## that stands for the empty symbol. |
| 1496 | This means that the empty symbol can now be read back. Also, #: by itself |
| 1497 | (when not immediately followed by a possible symbol character) stands for |
| 1498 | an empty uninterned symbol. |
| 1499 | |
| 1500 | +++ |
| 1501 | ** New math functions `isnan', `copysign', `frexp', `ldexp'. |
| 1502 | |
| 1503 | ** Obsolete functions and variables |
| 1504 | |
| 1505 | --- |
| 1506 | *** `tooltip-use-echo-area' is obsolete. |
| 1507 | Rather than setting this to t, disable Tooltip mode instead. |
| 1508 | |
| 1509 | +++ |
| 1510 | *** buffer-substring-filters is obsolete. |
| 1511 | Use `filter-buffer-substring-functions' instead. |
| 1512 | |
| 1513 | --- |
| 1514 | *** `byte-compile-disable-print-circle' is obsolete. |
| 1515 | |
| 1516 | --- |
| 1517 | *** `deferred-action-list' and `deferred-action-function' are obsolete. |
| 1518 | Use `post-command-hook' instead. |
| 1519 | |
| 1520 | +++ |
| 1521 | *** `font-lock-maximum-size' is obsolete. |
| 1522 | |
| 1523 | \f |
| 1524 | * Changes in Emacs 24.1 on non-free operating systems |
| 1525 | |
| 1526 | --- |
| 1527 | ** On MS Windows, Emacs warns when using the obsolete init file _emacs, |
| 1528 | and also when HOME is set to C:\ by default. |
| 1529 | |
| 1530 | ** New configure.bat options |
| 1531 | |
| 1532 | +++ |
| 1533 | *** --enable-checking builds Emacs with extra runtime checks. |
| 1534 | |
| 1535 | +++ |
| 1536 | *** --distfiles specifies files to be included in binary distribution. |
| 1537 | |
| 1538 | +++ |
| 1539 | *** --without-gnutls disables automatic GnuTLS detection. |
| 1540 | |
| 1541 | +++ |
| 1542 | *** --lib for general library linkage, works with the USER_LIBS build variable. |
| 1543 | |
| 1544 | +++ |
| 1545 | ** New make target `dist' to create binary distribution for MS Windows. |
| 1546 | |
| 1547 | --- |
| 1548 | ** The Lisp function `w32-default-color-map' is now obsolete. |
| 1549 | (It is only used internally in the Emacs C code.) |
| 1550 | |
| 1551 | +++ |
| 1552 | ** Customize ns-auto-hide-menu-bar to have the menu-bar hidden, but |
| 1553 | reappear on mouse-over. (Requires OS X 10.6 or later.) |
