| 25 | * Installation Changes in Emacs 24.1 |
| 26 | |
| 27 | ** Configure links against libselinux if it is found. |
| 28 | You can disable this by using --without-selinux. |
| 29 | |
| 30 | --- |
| 31 | ** By default, the installed Info and man pages are compressed. |
| 32 | You can disable this by configuring --without-compress-info. |
| 33 | |
| 34 | --- |
| 35 | ** There are new configure options: |
| 36 | --with-mmdf, --with-mail-unlink, --with-mailhost. |
| 37 | These provide no new functionality, they just remove the need to edit |
| 38 | lib-src/Makefile by hand in order to use the associated features. |
| 39 | |
| 40 | --- |
| 41 | ** Emacs can be compiled against Gtk+ 3.0 if you pass --with-x-toolkit=gtk3 |
| 42 | to configure. Note that other libraries used by Emacs, RSVG and GConf, |
| 43 | also depend on Gtk+. You can disable them with --without-rsvg and |
| 44 | --without-gconf. |
| 45 | |
| 46 | ** There is a new configure option --enable-use-lisp-union-type. |
| 47 | This is only useful for Emacs developers to debug certain types of bugs. |
| 48 | This is not a new feature; only the configure flag is new. |
| 49 | |
| 50 | --- |
| 51 | ** New translation of the Emacs Tutorial in Hebrew is available |
| 52 | Type `C-u C-h t' to choose it in case your language setup doesn't |
| 53 | automatically select it. |
| 54 | |
| 55 | \f |
| 56 | * Startup Changes in Emacs 24.1 |
| 57 | |
| 58 | ** The --unibyte, --multibyte, --no-multibyte, and --no-unibyte |
| 59 | command line arguments, and the EMACS_UNIBYTE environment variable, no |
| 60 | longer have any effect. (They were declared obsolete in Emacs 23.) |
| 61 | |
| 62 | ** New command line option `--no-site-lisp' removes site-lisp directories |
| 63 | from load-path. -Q now implies this. |
| 64 | |
| 65 | \f |
| 66 | * Changes in Emacs 24.1 |
| 67 | |
| 68 | ** emacsclient changes |
| 69 | |
| 70 | *** New emacsclient argument --parent-id ID can be used to open a |
| 71 | client frame in parent X window ID, via XEmbed. This works like the |
| 72 | --parent-id argument to Emacs. |
| 73 | |
| 74 | *** If emacsclient shuts down as a result of Emacs signalling an |
| 75 | error, its exit status is 1. |
| 76 | |
| 77 | ** Completion can cycle, depending on completion-cycle-threshold. |
| 78 | |
| 79 | ** auto-mode-case-fold is now enabled by default. |
| 80 | |
| 81 | +++ |
| 82 | ** Emacs now supports display and editing of bidirectional text. |
| 83 | |
| 84 | See the node "Bidirectional Editing" in the Emacs Manual for some |
| 85 | initial documentation. |
| 86 | |
| 87 | To turn this on in any given buffer, set the buffer-local variable |
| 88 | `bidi-display-reordering' to a non-nil value. The default is nil. |
| 89 | |
| 90 | The buffer-local variable `bidi-paragraph-direction', if non-nil, |
| 91 | forces each paragraph in the buffer to have its base direction |
| 92 | according to the value of this variable. Possible values are |
| 93 | `right-to-left' and `left-to-right'. If the value is nil (the |
| 94 | default), Emacs determines the base direction of each paragraph from |
| 95 | its text, as specified by the Unicode Bidirectional Algorithm. |
| 96 | |
| 97 | The function `current-bidi-paragraph-direction' returns the actual |
| 98 | value of paragraph base direction at point. |
| 99 | |
| 100 | Reordering of bidirectional text for display in Emacs is a "Full |
| 101 | bidirectionality" class implementation of the Unicode Bidirectional |
| 102 | Algorithm. |
| 103 | |
| 104 | Note that some advanced display features, such as overlay strings and |
| 105 | `display' text properties, do not yet work correctly when |
| 106 | bidirectional text is reordered for display. |
| 107 | |
| 108 | ** GTK scroll-bars are now placed on the right by default. |
| 109 | Use `set-scroll-bar-mode' to change this. |
| 110 | |
| 111 | ** GTK tool bars can have just text, just images or images and text. |
| 112 | Customize `tool-bar-style' to choose style. On a Gnome desktop, the default |
| 113 | is taken from the desktop settings. |
| 114 | |
| 115 | ** GTK tool bars can be placed on the left/right or top/bottom of the frame. |
| 116 | The frame-parameter tool-bar-position controls this. It takes the values |
| 117 | top, left, right or bottom. The Options => Show/Hide menu has entries |
| 118 | for this. |
| 119 | |
| 120 | ** ImageMagick support. |
| 121 | It is now possible to use the ImageMagick library to load many new |
| 122 | image formats in Emacs. By default, Emacs links with the ImageMagick |
| 123 | libraries if they are present at build time. To disable this, use |
| 124 | the configure option `--without-imagemagick'. |
| 125 | |
| 126 | The new function `imagemagick-types' returns a list of image file |
| 127 | extensions that your installation of ImageMagick supports. The |
| 128 | function `imagemagick-register-types' enables ImageMagick support for |
| 129 | these image types, minus those listed in `imagemagick-types-inhibit'. |
| 130 | |
| 131 | See the Emacs Lisp Reference Manual for more information. |
| 132 | |
| 133 | ** The colors for selected text (the region face) are taken from the GTK |
| 134 | theme when Emacs is built with GTK. |
| 135 | |
| 136 | ** Emacs uses GTK tooltips by default if built with GTK. You can turn that |
| 137 | off by customizing x-gtk-use-system-tooltips. |
| 138 | |
| 139 | ** Lucid menus and dialogs can display antialiased fonts if Emacs is built |
| 140 | with Xft. To change font, use the X resource font, for example: |
| 141 | Emacs.pane.menubar.font: Courier-12 |
| 142 | |
| 143 | +++ |
| 144 | ** Enhanced support for characters that have no glyphs in available fonts |
| 145 | If a character has no glyphs in any of the available fonts, Emacs by |
| 146 | default will display it either as a hexadecimal code in a box or as a |
| 147 | thin 1-pixel space. In addition to these two methods, Emacs can |
| 148 | display these characters as empty box, as an acronym, or not display |
| 149 | them at all. To change how these characters are displayed, customize |
| 150 | the variable `glyphless-char-display-control'. |
| 151 | |
| 152 | On character terminals these methods are used for characters that |
| 153 | cannot be encoded by the `terminal-coding-system'. |
| 154 | |
| 155 | ** On graphical displays, the mode-line no longer ends in dashes. |
| 156 | |
| 157 | ** Basic SELinux support has been added. |
| 158 | This requires Emacs to be linked with libselinux at build time. |
| 159 | |
| 160 | *** Emacs preserves the SELinux file context when backing up, and |
| 161 | optionally when copying files. To this end, copy-file has an extra |
| 162 | optional argument, and backup-buffer and friends include the SELinux |
| 163 | context in their return values. |
| 164 | |
| 165 | *** The new functions file-selinux-context and set-file-selinux-context |
| 166 | get and set the SELinux context of a file. |
| 167 | |
| 168 | *** Tramp offers handlers for file-selinux-context and set-file-selinux-context |
| 169 | for remote machines which support SELinux. |
| 170 | |
| 171 | +++ |
| 172 | ** The function format-time-string now supports the %N directive, for |
| 173 | higher-resolution time stamps. |
| 174 | |
| 175 | ** The function kill-emacs is now run upon receipt of the signals SIGTERM |
| 176 | and SIGHUP, and upon SIGINT in batch mode. |
| 177 | |
| 178 | ** kill-emacs-hook is now also run in batch mode. |
| 179 | |
| 180 | ** New scrolling commands `scroll-up-command' and `scroll-down-command' |
| 181 | (bound to C-v/[next] and M-v/[prior]) does not signal errors at top/bottom |
| 182 | of buffer at first key-press (instead moves to top/bottom of buffer) |
| 183 | when a new variable `scroll-error-top-bottom' is non-nil. |
| 184 | |
| 185 | ** New scrolling commands `scroll-up-line' and `scroll-down-line' |
| 186 | scroll a line instead of full screen. |
| 187 | |
| 188 | ** New property `scroll-command' should be set on a command's symbol to |
| 189 | define it as a scroll command affected by `scroll-preserve-screen-position'. |
| 190 | |
| 191 | ** Trash changes |
| 192 | |
| 193 | *** `delete-by-moving-to-trash' now only affects commands that specify |
| 194 | trashing. This avoids inadvertently trashing temporary files. |
| 195 | |
| 196 | *** Calling `delete-file' or `delete-directory' with a prefix argument |
| 197 | now forces true deletion, regardless of `delete-by-moving-to-trash'. |
| 198 | |
| 199 | ** New option `list-colors-sort' defines the color sort order |
| 200 | for `list-colors-display'. |
| 201 | |
| 202 | ** An Emacs Lisp package manager is now included. |
| 203 | This is a convenient way to download and install additional packages, |
| 204 | from a package repository at elpa.gnu.org. |
| 205 | |
| 206 | *** `M-x list-packages' shows a list of packages, which can be |
| 207 | selected for installation. |
| 208 | |
| 209 | *** New command `describe-package', bound to `C-h P'. |
| 210 | |
| 211 | *** By default, all installed packages are loaded and activated |
| 212 | automatically when Emacs starts up. To disable this, set |
| 213 | `package-enable-at-startup' to nil. To change which packages are |
| 214 | loaded, customize `package-load-list'. |
| 215 | |
| 216 | ** An Emacs Lisp testing tool is now included. |
| 217 | Emacs Lisp developers can use this tool to write automated tests for |
| 218 | their code. See the ERT info manual for details. |
| 219 | |
| 220 | ** Custom Themes |
| 221 | |
| 222 | *** `M-x customize-themes' lists Custom themes which can be enabled. |
| 223 | |
| 224 | *** New option `custom-theme-load-path' is the load path for themes. |
| 225 | Emacs no longer looks for custom themes in `load-path'. The default |
| 226 | is to search in `custom-theme-directory', followed by a built-in theme |
| 227 | directory named "themes/" in `data-directory'. |
| 228 | |
| 229 | *** New option `custom-safe-themes' records known-safe theme files. |
| 230 | If a theme is not in this list, Emacs queries before loading it, and |
| 231 | offers to save the theme to `custom-safe-themes' automatically. By |
| 232 | default, all themes included in Emacs are treated as safe. |
| 233 | |
| 234 | ** The user option `remote-file-name-inhibit-cache' controls whether |
| 235 | the remote file-name cache is used for read access. |
| 236 | |
| 237 | ** The standalone programs lib-src/digest-doc and sorted-doc have been |
| 238 | replaced with Lisp commands `doc-file-to-man' and `doc-file-to-info'. |
| 239 | |
| 240 | ** The variable `focus-follows-mouse' now always defaults to nil. |
| 241 | |
| 242 | \f |
| 243 | * Editing Changes in Emacs 24.1 |
| 244 | |
| 245 | +++ |
| 246 | ** There is a new command `count-words-region', which does what you expect. |
| 247 | |
| 248 | ** completion-at-point now handles tags and semantic completion. |
| 249 | |
| 250 | ** The default value of `backup-by-copying-when-mismatch' is now t. |
| 251 | |
| 252 | ** The command `just-one-space' (C-SPC), if given a negative argument, |
| 253 | also deletes newlines around point. |
| 254 | |
| 255 | ** Deletion changes |
| 256 | |
| 257 | *** New option `delete-active-region'. |
| 258 | If non-nil, C-d, [delete], and DEL delete the region if it is active |
| 259 | and no prefix argument is given. If set to `kill', these commands |
| 260 | kill instead. |
| 261 | |
| 262 | *** New command `delete-forward-char', bound to C-d and [delete]. |
| 263 | This is meant for interactive use, and obeys `delete-active-region'. |
| 264 | The command `delete-char' does not obey `delete-active-region'. |
| 265 | |
| 266 | *** `delete-backward-char' is now a Lisp function. |
| 267 | Apart from obeying `delete-active-region', its behavior is unchanged. |
| 268 | However, the byte compiler now warns if it is called from Lisp; you |
| 269 | should use delete-char with a negative argument instead. |
| 270 | |
| 271 | *** The option `mouse-region-delete-keys' has been deleted. |
| 272 | |
| 273 | ** Selection changes. |
| 274 | |
| 275 | The default handling of clipboard and primary selections was changed |
| 276 | to conform with modern X applications. In short, most commands for |
| 277 | killing and yanking text now use the clipboard, while mouse commands |
| 278 | use the primary selection. |
| 279 | |
| 280 | In the following, we provide a list of these changes, followed by a |
| 281 | list of steps to get the old behavior back if you prefer that. |
| 282 | |
| 283 | *** `mouse-drag-copy-region' now defaults to nil. |
| 284 | *** `select-active-regions' now defaults to t. |
| 285 | Merely selecting text (e.g. with drag-mouse-1) no longer puts it in |
| 286 | the kill-ring. The selected text is put in the primary selection, if |
| 287 | the system possesses a separate primary selection facility (e.g. X). |
| 288 | |
| 289 | **** `select-active-regions' also accepts a new value, `only'. |
| 290 | This means to only set the primary selection for temporarily active |
| 291 | regions (usually made by mouse-dragging or shift-selection); |
| 292 | "ordinary" active regions, such as those made with C-SPC followed by |
| 293 | point motion, do not alter the primary selection. |
| 294 | |
| 295 | *** mouse-2 is now bound to `mouse-yank-primary'. |
| 296 | This pastes from the primary selection, ignoring the kill-ring. |
| 297 | Previously, mouse-2 was bound to `mouse-yank-at-click'. |
| 298 | |
| 299 | *** `x-select-enable-clipboard' now defaults to t on all platforms. |
| 300 | *** `x-select-enable-primary' now defaults to nil. |
| 301 | Thus, commands that kill text or copy it to the kill-ring (such as |
| 302 | M-w, C-w, and C-k) also use the clipboard---not the primary selection. |
| 303 | |
| 304 | **** The "Copy", "Cut", and "Paste" items in the "Edit" menu are now |
| 305 | exactly equivalent to, respectively M-w, C-w, and C-y. |
| 306 | |
| 307 | **** Note that on MS-Windows, `x-select-enable-clipboard' was already |
| 308 | non-nil by default, as Windows does not support the primary selection |
| 309 | between applications. |
| 310 | |
| 311 | *** To return to the previous behavior, do the following: |
| 312 | |
| 313 | **** Change `mouse-drag-copy-region' to t. |
| 314 | **** Change `x-select-enable-primary' to t (on X only). |
| 315 | **** Change `x-select-enable-clipboard' to nil. |
| 316 | **** Bind `mouse-yank-at-click' to mouse-2. |
| 317 | |
| 318 | *** Support for X cut buffers has been removed. |
| 319 | |
| 320 | ** New command `rectangle-number-lines', bound to `C-x r N', numbers |
| 321 | the lines in the current rectangle. With an prefix argument, this |
| 322 | prompts for a number to count from and for a format string. |
| 323 | |
| 324 | \f |
| 325 | * Changes in Specialized Modes and Packages in Emacs 24.1 |
| 326 | |
| 327 | ** The compile.el mode can be used without font-lock-mode. |
| 328 | `compilation-parse-errors-function' is now obsolete. |
| 329 | |
| 330 | ** The Landmark game is now invoked with `landmark', not `lm'. |
| 331 | |
| 332 | ** Prolog mode has been completely revamped, with lots of additional |
| 333 | functionality such as more intelligent indentation, electricty, support for |
| 334 | more variants, including Mercury, and a lot more. |
| 335 | |
| 336 | ** shell-mode can track your cwd by reading it from your prompt. |
| 337 | Just set shell-dir-cookie-re to an appropriate regexp. |
| 338 | |
| 339 | ** Modula-2 mode provides auto-indentation. |
| 340 | |
| 341 | ** latex-electric-env-pair-mode keeps \begin..\end matched on the fly. |
| 342 | |
| 343 | ** FIXME: xdg-open for browse-url and reportbug, 2010/08. |
| 344 | |
| 345 | ** Archive Mode has basic support to browse 7z archives. |
| 346 | |
| 347 | ** browse-url has gotten a new variable that is used for mailto: URLs, |
| 348 | `browse-url-mailto-function', which defaults to `browse-url-mail'. |
| 349 | |
| 350 | ** ERC changes |
| 351 | |
| 352 | *** New vars `erc-autojoin-timing' and `erc-autojoin-delay'. |
| 353 | If the value of `erc-autojoin-timing' is 'ident, ERC autojoins after a |
| 354 | successful NickServ identification, or after `erc-autojoin-delay' |
| 355 | seconds. The default value, 'ident, means to autojoin immediately |
| 356 | after connecting. |
| 357 | |
| 358 | *** New variable `erc-coding-system-precedence': If we use `undecided' |
| 359 | as the server coding system, this variable will then be consulted. |
| 360 | The default is to decode strings that can be decoded as utf-8 as |
| 361 | utf-8, and do the normal `undecided' decoding for the rest. |
| 362 | |
| 363 | ** Eshell changes |
| 364 | |
| 365 | *** The default value of eshell-directory-name is a directory named |
| 366 | "eshell" in `user-emacs-directory'. If the old "~/.eshell/" directory |
| 367 | exists, that is used instead. |
| 368 | |
| 369 | ** In ido-mode, C-v is no longer bound to ido-toggle-vc. |
| 370 | The reason is that this interferes with cua-mode. |
| 371 | |
| 372 | ** partial-completion-mode is now obsolete. |
| 373 | You can get a comparable behavior with: |
| 374 | (setq completion-styles '(partial-completion initials)) |
| 375 | (setq completion-pcm-complete-word-inserts-delimiters t) |
| 376 | |
| 377 | ** mpc.el: Can use pseudo tags of the form tag1|tag2 as a union of two tags. |
| 378 | |
| 379 | ** server can listen on a specific port using the server-port option. |
| 380 | |
| 381 | ** Calendar, Diary, and Appt |
| 382 | |
| 383 | --- |
| 384 | *** The obsolete (since Emacs 22.1) method of enabling the appt package |
| 385 | by adding appt-make-list to diary-hook has been removed. Use appt-activate. |
| 386 | |
| 387 | --- |
| 388 | *** Some appt variables (obsolete since Emacs 22.1) have been removed: |
| 389 | appt-issue-message (use the function appt-activate) |
| 390 | appt-visible/appt-msg-window (use the variable appt-display-format) |
| 391 | |
| 392 | --- |
| 393 | *** Some diary function aliases (obsolete since Emacs 22.1) have been removed: |
| 394 | view-diary-entries, list-diary-entries, show-all-diary-entries |
| 395 | |
| 396 | ** Customize |
| 397 | |
| 398 | *** Customize buffers now contain a search field. |
| 399 | The search is performed using `customize-apropos'. |
| 400 | To turn off the search field, set custom-search-field to nil. |
| 401 | |
| 402 | *** Custom options now start out hidden if at their default values. |
| 403 | Use the arrow to the left of the option name to toggle visibility. |
| 404 | |
| 405 | *** custom-buffer-sort-alphabetically now defaults to t. |
| 406 | |
| 407 | *** The color widget now has a "Choose" button, which allows you to |
| 408 | choose a color via list-colors-display. |
| 409 | |
| 410 | ** Dired-x |
| 411 | |
| 412 | *** dired-jump and dired-jump-other-window called with a prefix argument |
| 413 | read a file name from the minibuffer instead of using buffer-file-name. |
| 414 | |
| 415 | ** Directory local variables can apply to file-less buffers. |
| 416 | For example, adding "(diff-mode . ((mode . whitespace)))" to your |
| 417 | .dir-locals.el file, will turn on `whitespace-mode' for *vc-diff* buffers. |
| 418 | |
| 419 | ** SQL Mode enhancements. |
| 420 | |
| 421 | *** Several variables have been marked as safe local variables. The |
| 422 | variables `sql-product', `sql-user', `sql-server', `sql-database' and |
| 423 | `sql-port' can now be safely used as local variables. |
| 424 | |
| 425 | *** `sql-dialect' is a synonym for `sql-product'. |
| 426 | |
| 427 | *** Added ability to login with a port on MySQL and Postgres. |
| 428 | The custom variable `sql-port' can be specified for connection to |
| 429 | MySQL or Postgres servers. By default, the port is not listed in |
| 430 | either login parameter, but will be added to the command line if set |
| 431 | to a non-zero value. |
| 432 | |
| 433 | *** Dynamic selection of product in an SQL interactive session. |
| 434 | If you use `sql-product-interactive' to start an SQL interactive |
| 435 | session it uses the current value of `sql-product'. Preceding the |
| 436 | invocation with C-u will force it to ask for the product before |
| 437 | creating the session. |
| 438 | |
| 439 | *** Renaming a SQL interactive buffer when it is created. |
| 440 | Prefixing the SQL interactive commands (`sql-sqlite', `sql-postgres', |
| 441 | `sql-mysql', etc.) with C-u will force a new interactive session to be |
| 442 | started and will prompt for the new name. This will reduce the need |
| 443 | for `sql-rename-buffer' is most common use cases. |
| 444 | |
| 445 | *** Command continuation prompts in SQL interactive mode are suppressed. |
| 446 | Multiple line commands in SQL interactive mode, generate command |
| 447 | continuation prompts which needlessly confuse the output. These |
| 448 | prompts are now filtered out from the output. This change impacts |
| 449 | multiple line SQL statements entered with C-j between each line, |
| 450 | statements yanked into the buffer and statements sent with |
| 451 | `sql-send-*' functions. |
| 452 | |
| 453 | *** Custom variables control prompting for login parameters. |
| 454 | Each supported product has a custom variable `sql-*-login-params' |
| 455 | which is a list of the parameters to be prompted for before a |
| 456 | connection is established. |
| 457 | |
| 458 | The lists consist of the following five tokens: `user', `password', |
| 459 | `database', `server', and `port'. The order in which they appear is |
| 460 | the order in which they are prompted. The tokens symbols can be |
| 461 | replaced by a sublist starting with the token and followed by a plist |
| 462 | which control the prompting for values. The tokens `user', |
| 463 | `database', and `server' each can take a property of :default which |
| 464 | specifies the value to be used if no value is entered. The |
| 465 | `database', `server', and `port' tokens handle the :completion |
| 466 | property which restricts the entry to either one of the values in the |
| 467 | list or to one of the values returned by the function provided as the |
| 468 | property value. The `database' and `server' tokens also accept the |
| 469 | :file property whose value is a regexp to identify useful file names. |
| 470 | |
| 471 | (user :default DEF) |
| 472 | (database :default DEF |
| 473 | :file FILEPAT |
| 474 | :completion COMPLETE) |
| 475 | (server :default DEF |
| 476 | :file FILEPAT |
| 477 | :completion COMPLETE) |
| 478 | |
| 479 | The FILEPAT when :file is specified is a regexp that will match valid |
| 480 | file names (without the directory portion). Generally these strings |
| 481 | will be of the form ".+\.SUF" where SUF is the desired file suffix. |
| 482 | |
| 483 | When :completion is specified, the COMPLETE corresponds to the |
| 484 | PREDICATE argument to the `completing-read' function (a list of |
| 485 | possible values or a function returning such a list). |
| 486 | |
| 487 | *** Added `sql-connection-alist' to record login parameter values. |
| 488 | An alist for recording different username, database and server |
| 489 | values. If there are multiple databases that you connect to the |
| 490 | parameters needed can be stored in this alist. |
| 491 | |
| 492 | For example, the following might be set in the user's init.el: |
| 493 | |
| 494 | (setq sql-connection-alist |
| 495 | '((dev (sql-product 'sqlite) |
| 496 | (sql-database "/home/mmaug/dev.db")) |
| 497 | (prd (sql-product 'oracle) |
| 498 | (sql-user "mmaug") |
| 499 | (sql-database "iprd2a")))) |
| 500 | |
| 501 | This defines two connections named "dev" and "prd". |
| 502 | |
| 503 | *** Added `sql-connect' to use predefined connections. |
| 504 | Sets the login parameters based on the values in the |
| 505 | `sql-connection-alist' and start a SQL interactive session. Any |
| 506 | values specified in the connection will not be prompted for. |
| 507 | |
| 508 | In the example above, if the user were to invoke M-x sql-connect, they |
| 509 | would be prompted for the connection. The user can respond with |
| 510 | either "dev" or "prd". The "dev" connection would connect to the |
| 511 | SQLite database without prompting; the "prd" connection would prompt |
| 512 | for the users password and then connect to the Oracle database. |
| 513 | |
| 514 | **** Added SQL->Start... submenu when connections are defined. |
| 515 | When connections have been defined, there is a submenu available that |
| 516 | allows the user to select one to start a SQLi session. The "Start |
| 517 | SQLi Session" item moves to the "Start..." submenu when cnnections |
| 518 | have been defined. |
| 519 | |
| 520 | **** Added "Save Connection" menu item in SQLi buffers. |
| 521 | When a SQLi session is not started by a connection then |
| 522 | `sql-save-connection' will gather the login params specified for the |
| 523 | session and save them as a new connection. |
| 524 | |
| 525 | *** List database objects and details. |
| 526 | Once a SQL interactive session has been started, you can get a list of |
| 527 | the objects in the database and see details of those objects. The |
| 528 | objects shown and the details available are product specific. |
| 529 | |
| 530 | **** List all objects. |
| 531 | Using `M-x sql-list-all', `C-c C-l a' or selecting "SQL->List all |
| 532 | objects" will list all the objects in the database. At a minimum it |
| 533 | lists the tables and views in the database. Preceeding the command by |
| 534 | universal argument may provide additional details or extend the |
| 535 | listing to include other schemas objects. The list will appear in a |
| 536 | separate window in view-mode. |
| 537 | |
| 538 | **** List Table details. |
| 539 | Using `M-x sql-list-table', `C-c C-l t' or selecting "SQL->List Table |
| 540 | details" will ask for the name of a database table or view and display |
| 541 | the list of columns in the relation. Preceeding the comand with the |
| 542 | universal argument may provide additional details about each column. |
| 543 | The list will appear in a separate window in view-mode. |
| 544 | |
| 545 | *** Added option `sql-send-terminator'. |
| 546 | When set makes sure that each command sent with `sql-send-*' commands |
| 547 | are properly terminated and submitted to the SQL processor. |
| 548 | |
| 549 | *** Added option `sql-oracle-scan-on'. |
| 550 | When set commands sent to Oracle's SQL*Plus are scanned for strings |
| 551 | starting with an ampersand and the user is asked for replacement text. |
| 552 | In general, the SQL*Plus option SCAN should always be set OFF under |
| 553 | SQL interactive mode and this option used in its place. |
| 554 | |
| 555 | *** SQL interactive mode will replace tabs with spaces. |
| 556 | This prevents the comand interpretter for MySQL and Postgres from |
| 557 | listing object name completions when being sent text via |
| 558 | `sql-send-*' functions. |
| 559 | |
| 560 | *** An API for manipulating SQL product definitions has been added. |
| 561 | |
| 562 | ** sregex.el is now obsolete, since rx.el is a strict superset. |
| 563 | |
| 564 | ** s-region.el and pc-select are now declared obsolete, |
| 565 | superceded by shift-select-mode enabled by default in 23.1. |
| 566 | ** pc-mode.el is also declared obsolete. |
| 567 | ** gdb-mi |
| 568 | |
| 569 | *** GDB User Interface migrated to GDB Machine Interface and now |
| 570 | supports multithread non-stop debugging and debugging of several |
| 571 | threads simultaneously. |
| 572 | |
| 573 | ** D-Bus |
| 574 | |
| 575 | *** It is possible now, to access alternative buses than the default |
| 576 | system or session bus. |
| 577 | |
| 578 | *** dbus-register-{service,method,property} |
| 579 | The -method and -property functions do not automatically register |
| 580 | names anymore. |
| 581 | |
| 582 | The new function dbus-register-service registers a service known name |
| 583 | on a D-Bus without simultaneously registering a property or a method. |
| 584 | |
| 585 | ** Tramp |
| 586 | |
| 587 | *** There exists a new inline access method "ksu" (kerberized su). |
| 588 | |
| 589 | *** The following access methods are discontinued: "ssh1_old", |
| 590 | "ssh2_old", "scp1_old", "scp2_old", "imap", "imaps" and "fish". |
| 591 | |
| 592 | ** VC and related modes |
| 593 | |
| 594 | *** Support for pulling on distributed version control systems. |
| 595 | The vc-pull command runs a "pull" operation, if it is supported. |
| 596 | This updates the current branch from upstream. A prefix argument |
| 597 | means to prompt the user for specifics, e.g. a pull location. |
| 598 | |
| 599 | **** `vc-update' is now an alias for `vc-pull'. |
| 600 | |
| 601 | **** Currently supported by Bzr, Git, and Mercurial. |
| 602 | |
| 603 | *** Support for merging on distributed version control systems. |
| 604 | The vc-merge command now runs a "merge" operation, if it is supported. |
| 605 | This merges another branch into the current one. This command prompts |
| 606 | the user for specifics, e.g. a merge source. |
| 607 | |
| 608 | **** Currently supported for Bzr, Git, and Mercurial. |
| 609 | |
| 610 | *** Log entries in some Log View buffers can be toggled to display a |
| 611 | longer description by typing RET (log-view-toggle-entry-display). |
| 612 | In the Log View buffers made by `C-x v L' (vc-print-root-log), you can |
| 613 | use this to display the full log entry for the revision at point. |
| 614 | |
| 615 | **** Currently supported for Bzr, Git, and Mercurial. |
| 616 | |
| 617 | **** Packages using Log View mode can enable this functionality by |
| 618 | binding `log-view-expanded-log-entry-function' to a suitable function. |
| 619 | |
| 620 | ** Miscellaneous |
| 621 | |
| 622 | --- |
| 623 | *** `copyright-fix-years' can optionally convert consecutive years to ranges. |
| 624 | |
| 625 | \f |
| 626 | * New Modes and Packages in Emacs 24.1 |
| 627 | |
| 628 | ** New global minor modes electric-pair-mode, electric-indent-mode, |
| 629 | and electric-layout-mode. |
| 630 | |
| 631 | ** pcase.el provides the ML-style pattern matching macro `pcase'. |
| 632 | |
| 633 | ** secrets.el is an implementation of the Secret Service API, an |
| 634 | interface to password managers like GNOME Keyring or KDE Wallet. The |
| 635 | Secret Service API requires D-Bus for communication. The command |
| 636 | `secrets-show-secrets' offers a buffer with a visualization of the |
| 637 | secrets. |
| 638 | |
| 639 | ** notifications.el provides an implementation of the Desktop |
| 640 | Notifications API. It requires D-Bus for communication. |
| 641 | |
| 642 | \f |
| 643 | * Incompatible Lisp Changes in Emacs 24.1 |
| 644 | |
| 645 | ** `copy-directory' now copies the source directory as a subdirectory |
| 646 | of the target directory, if the latter is an existing directory. The |
| 647 | new optional arg COPY-CONTENTS, if non-nil, makes the function copy |
| 648 | the contents directly into a pre-existing target directory. |
| 649 | |
| 650 | ** `compose-mail' now accepts an optional 8th arg, RETURN-ACTION, and |
| 651 | passes it to the mail user agent function. This argument specifies an |
| 652 | action for returning to the caller after finishing with the mail. |
| 653 | This is currently used by Rmail to delete a mail window. |
| 654 | |
| 655 | ** For mouse click input events in the text area, the Y pixel |
| 656 | coordinate in the POSITION list now counts from the top of the text |
| 657 | area, excluding any header line. Previously, it counted from the top |
| 658 | of the header line. |
| 659 | |
| 660 | ** Remove obsolete name `e' (use `float-e' instead). |
| 661 | |
| 662 | ** A backquote not followed by a space is now always treated as new-style. |
| 663 | |
| 664 | ** Test for special mode-class was moved from view-file to view-buffer. |
| 665 | FIXME: This only says what was changed, but not what are the |
| 666 | programmer-visible consequences. |
| 667 | |
| 668 | ** Passing a nil argument to a minor mode function now turns the mode |
| 669 | ON unconditionally. |
| 670 | |
| 671 | ** During startup, Emacs no longer adds entries for `menu-bar-lines' |
| 672 | and `tool-bar-lines' to `default-frame-alist' and |
| 673 | `initial-frame-alist'. With these alist entries omitted, `make-frame' |
| 674 | checks the value of the variable `menu-bar-mode'/`tool-bar-mode' to |
| 675 | determine whether to create a menu-bar or tool-bar, respectively. |
| 676 | If the alist entries are added, they override the value of |
| 677 | `menu-bar-mode'/`tool-bar-mode'. |
| 678 | |
| 679 | ** Regions created by mouse dragging are now normal active regions, |
| 680 | similar to the ones created by shift-selection. In previous Emacs |
| 681 | versions, these regions were delineated by `mouse-drag-overlay', which |
| 682 | has now been removed. |
| 683 | |
| 684 | ** cl.el no longer provides `cl-19'. |
| 685 | |
| 686 | ** The following functions and aliases, obsolete since at least Emacs 21.1, |
| 687 | have been removed: |
| 688 | comint-kill-output, decompose-composite-char, outline-visible, |
| 689 | internal-find-face, internal-get-face, frame-update-faces, |
| 690 | frame-update-face-colors, x-frob-font-weight, x-frob-font-slant, |
| 691 | x-make-font-bold, x-make-font-demibold, x-make-font-unbold |
| 692 | x-make-font-italic, x-make-font-oblique, x-make-font-unitalic |
| 693 | x-make-font-bold-italic, mldrag-drag-mode-line, mldrag-drag-vertical-line, |
| 694 | iswitchb-default-keybindings, char-bytes, isearch-return-char, |
| 695 | make-local-hook |
| 696 | |
| 697 | ** The following variables and aliases, obsolete since at least Emacs 21.1, |
| 698 | have been removed: |
| 699 | checkdoc-minor-keymap, vc-header-alist, directory-sep-char, |
| 700 | font-lock-defaults-alist |
| 701 | |
| 702 | ** The following files, obsolete since at least Emacs 21.1, have been removed: |
| 703 | sc.el, x-menu.el, rnews.el, rnewspost.el |
| 704 | |
| 705 | ** FIXME finder-inf.el changes. |
| 706 | |
| 707 | \f |
| 708 | * Lisp changes in Emacs 24.1 |
| 709 | |
| 710 | ** Removed the stack-trace-on-error variable. |
| 711 | Also the debugger can now "continue" from an error, which means it will jump |
| 712 | to the error handler as if the debugger had not been invoked instead of |
| 713 | jumping all the way to the top-level. |
| 714 | |
| 715 | ** New function `read-char-choice' reads a restricted set of characters, |
| 716 | discarding any inputs not inside the set. |
| 717 | |
| 718 | ** `image-library-alist' is renamed to `dynamic-library-alist'. |
| 719 | The variable is now used to load all kind of supported dynamic libraries, |
| 720 | not just image libraries. The previous name is still available as an |
| 721 | obsolete alias. |
| 722 | |
| 723 | ** New variable syntax-propertize-function to set syntax-table properties. |
| 724 | Replaces font-lock-syntactic-keywords which are now obsolete. |
| 725 | This allows syntax-table properties to be set independently from font-lock: |
| 726 | just call syntax-propertize to make sure the text is propertized. |
| 727 | Together with this new variable come a new hook |
| 728 | syntax-propertize-extend-region-functions, as well as two helper functions: |
| 729 | syntax-propertize-via-font-lock to reuse old font-lock-syntactic-keywords |
| 730 | as-is; and syntax-propertize-rules which provides a new way to specify |
| 731 | syntactic rules. |
| 732 | |
| 733 | ** New hook post-self-insert-hook run at the end of self-insert-command. |
| 734 | |
| 735 | +++ |
| 736 | ** Syntax tables support a new "comment style c" additionally to style b. |
| 737 | ** frame-local variables cannot be let-bound any more. |
| 738 | ** prog-mode is a new major-mode meant to be the parent of programming mode. |
| 739 | ** define-minor-mode accepts a new keyword :variable. |
| 740 | |
| 741 | ** `delete-file' and `delete-directory' now accept optional arg TRASH. |
| 742 | Trashing is performed if TRASH and `delete-by-moving-to-trash' are |
| 743 | both non-nil. Interactively, TRASH defaults to t, unless a prefix |
| 744 | argument is supplied (see Trash changes, above). |
| 745 | |
| 746 | ** buffer-substring-filters is obsoleted by filter-buffer-substring-functions. |
| 747 | |
| 748 | ** New completion style `substring'. |
| 749 | |
| 750 | ** `facemenu-read-color' is now an alias for `read-color'. |
| 751 | The command `read-color' now requires a match for a color name or RGB |
| 752 | triplet, instead of signalling an error if the user provides a invalid |
| 753 | input. |
| 754 | |
| 755 | ** Tool-bars can display separators. |
| 756 | Tool-bar separators are handled like menu separators in menu-bar maps, |
| 757 | i.e. via menu entries of the form `(menu-item "--")'. |
| 758 | |
| 759 | ** Image API |
| 760 | |
| 761 | *** When the image type is one of listed in `image-animated-types' |
| 762 | and the number of sub-images in the image is more than one, then the |
| 763 | new function `create-animated-image' creates an animated image where |
| 764 | sub-images are displayed successively with the duration defined by |
| 765 | `image-animate-max-time' and the delay between sub-images defined |
| 766 | by the Graphic Control Extension of the image. |
| 767 | |
| 768 | *** `image-extension-data' is renamed to `image-metadata'. |
| 769 | |
| 770 | ** XML and HTML parsing |
| 771 | |
| 772 | *** If Emacs is compiled with libxml2 support (which is the default), |
| 773 | two new Emacs Lisp-level functions are defined: |
| 774 | `libxml-parse-html-region' (which will parse "real world" HTML) |
| 775 | and `libxml-parse-xml-region' (which parses XML). Both return an |
| 776 | Emacs Lisp parse tree. |
| 777 | |
| 778 | FIXME: These should be front-ended by xml.el. |
| 779 | |
| 780 | ** FIXME GnuTLS |
| 781 | |
| 782 | ** Isearch |
| 783 | |
| 784 | *** New hook `isearch-update-post-hook' that runs in `isearch-update'. |
| 785 | |
| 786 | ** Progress reporters can now "spin". |
| 787 | The MIN-VALUE and MAX-VALUE arguments of `make-progress-reporter' can |
| 788 | now be nil, or omitted. This makes a "non-numeric" reporter. Each |
| 789 | time you call `progress-reporter-update' on that progress reporter, |
| 790 | with a nil or omitted VALUE argument, the reporter message is |
| 791 | displayed with a "spinning bar". |
| 792 | |
| 793 | \f |
| 794 | * Changes in Emacs 24.1 on non-free operating systems |
| 795 | |
| 796 | ** New configure.bat option --enable-checking builds emacs with extra |
| 797 | runtime checks. |
| 798 | |
| 799 | ** New configure.bat option --distfiles to specify files to be |
| 800 | included in binary distribution |
| 801 | |
| 802 | ** New make target `dist' to create binary disttribution for Windows |
| 803 | platform |
