| 334 | * Installation Changes in Emacs 24.4 | ||
| 335 | |||
| 336 | ** Emacs can now be compiled with ACL (access control list) support. | ||
| 337 | This happens by default if a suitable support library is found at | ||
| 338 | build time, like libacl on GNU/Linux. To prevent this, use the | ||
| 339 | configure option `--disable-acl'. See below for the features this provides. | ||
| 340 | |||
| 341 | ** Emacs can now be compiled with file notification support. | ||
| 342 | This happens by default if a suitable system library is found at | ||
| 343 | build time. To prevent this, use the configure option | ||
| 344 | `--without-file-notification'. See below for file-notify features. | ||
| 345 | This feature is not available for the Nextstep port. | ||
| 346 | |||
| 347 | ** Emacs can now be compiled with zlib support. | ||
| 348 | This happens by default if zlib is present, which it normally is. | ||
| 349 | To prevent this, use the configure option `--without-zlib'. | ||
| 350 | This provides the function `zlib-decompress-region'; see below for details. | ||
| 351 | |||
| 352 | ** The configure option `--without-compress-info' has been generalized, | ||
| 353 | and renamed to `--without-compress-install'. It now prevents compression | ||
| 354 | of _any_ files during installation. | ||
| 355 | |||
| 356 | ** The configure option `--with-crt-dir' has been removed. | ||
| 357 | It is no longer needed, as the crt*.o files are no longer linked specially. | ||
| 358 | |||
| 359 | ** Directories passed to configure option `--enable-locallisppath' are | ||
| 360 | no longer created during installation. | ||
| 361 | |||
| 362 | ** Emacs for Nextstep (Mac OS X, GNUstep) can be built with ImageMagick support. | ||
| 363 | This requires pkg-config to be available at build time. | ||
| 364 | |||
| 365 | |||
| 366 | * Startup Changes in Emacs 24.4 | ||
| 367 | |||
| 368 | ** When initializing `load-path', an empty element in the EMACSLOADPATH | ||
| 369 | environment variable (either leading, e.g., ":/foo"; trailing, e.g., | ||
| 370 | "/foo:"; or embedded, e.g., "/foo::/bar") is replaced with the default | ||
| 371 | load-path (the one that would have been used if EMACSLOADPATH was unset). | ||
| 372 | This makes it easier to _extend_ the load-path via EMACSLOADPATH | ||
| 373 | (previously, EMACSLOADPATH had to specify the complete load-path, | ||
| 374 | including the defaults). (In older versions of Emacs, an empty element | ||
| 375 | was replaced by ".", so use an explicit "." now if that is what you want.) | ||
| 376 | |||
| 377 | ** The -L option, which normally prepends its argument to load-path, | ||
| 378 | will instead append, if the argument begins with `:' (or `;' on MS Windows; | ||
| 379 | i.e., `path-separator'). | ||
| 380 | |||
| 381 | ** If you use either site-load.el or site-init.el to customize the dumped | ||
| 382 | Emacs executable, any changes to `load-path' that these files make | ||
| 383 | will no longer be present after dumping. To affect a permanent change | ||
| 384 | to `load-path', use the `--enable-locallisppath' option of `configure'. | ||
| 385 | |||
| 386 | ** The user option `initial-buffer-choice' can now specify a function | ||
| 387 | to set up the initial buffer. | ||
| 388 | |||
| 389 | |||
| 390 | * Changes in Emacs 24.4 | ||
| 391 | |||
| 392 | ** Support for ACLs (access control lists). | ||
| 393 | This requires a suitable support library to be found at build time. | ||
| 394 | On GNU/Linux, the POSIX ACL interface is used via libacl. | ||
| 395 | On MS-Windows, the NT Security APIs are used to emulate the POSIX interface. | ||
| 396 | ACLs are extended file attributes, used e.g. for finer-grained permissions. | ||
| 397 | |||
| 398 | *** Emacs preserves the ACL entries of files when backing up. | ||
| 399 | |||
| 400 | *** New functions `file-acl' and `set-file-acl' get and set file ACLs. | ||
| 401 | |||
| 402 | ** Support for menus on text-mode terminals. | ||
| 403 | If the terminal supports a mouse, clicking on the menu bar, or on | ||
| 404 | sensitive portions of the mode line or header line, will drop down the | ||
| 405 | menu defined at that position. Likewise, clicking C-mouse-1, C-mouse-2, or | ||
| 406 | C-mouse-3 on the text area will pop up the menus defined for those locations. | ||
| 407 | |||
| 408 | If the text terminal does not support a mouse, you can activate the | ||
| 409 | first menu-bar menu by typing F10, which invokes `menu-bar-open'. | ||
| 410 | |||
| 411 | If you want the previous behavior, where F10 invoked `tmm-menubar', | ||
| 412 | customize the option `tty-menu-open-use-tmm' to a non-nil value. | ||
| 413 | (Typing M-` always invokes `tmm-menubar', even if `tty-menu-open-use-tmm' | ||
| 414 | is nil.) | ||
| 415 | |||
| 416 | ** New option `load-prefer-newer' affects how the `load' function chooses | ||
| 417 | the file to load. If this is non-nil, then when both .el and .elc | ||
| 418 | versions of a file exist, and the caller did not explicitly specify | ||
| 419 | which one to load, then the newer file is loaded. The default, nil, | ||
| 420 | means to always load the .elc file. | ||
| 421 | |||
| 422 | ** Multi-monitor support | ||
| 423 | |||
| 424 | *** New functions `display-monitor-attributes-list' and | ||
| 425 | `frame-monitor-attributes' can be used to obtain information about | ||
| 426 | each physical monitor on multi-monitor setups. | ||
| 427 | |||
| 428 | *** The functions `display-pixel-width' and `display-pixel-height' now | ||
| 429 | behave consistently among the platforms: they return the pixel width | ||
| 430 | or height for all physical monitors associated with the given display | ||
| 431 | as if they were on X. To get information for each physical | ||
| 432 | monitor, use the new functions above. Similar notes also apply to | ||
| 433 | `x-display-pixel-width', `x-display-pixel-height', `display-mm-width', | ||
| 434 | `display-mm-height', `x-display-mm-width', and `x-display-mm-height'. | ||
| 435 | |||
| 436 | ** New function `zlib-decompress-region', which decompresses gzip- and | ||
| 437 | zlib-format compressed data using built-in zlib support (if available). | ||
| 438 | |||
| 439 | ** The *Messages* buffer is created in `messages-buffer-mode', | ||
| 440 | a new major mode, with read-only status. Any code that might create | ||
| 441 | the *Messages* buffer should call the function `messages-buffer' to do | ||
| 442 | so and set up the mode. | ||
| 443 | |||
| 444 | ** The cursor stops blinking after 10 blinks (by default) on X and Nextstep. | ||
| 445 | You can change the default by customizing `blink-cursor-blinks'. | ||
| 446 | |||
| 447 | ** In keymaps where SPC scrolls forward, S-SPC now scrolls backward. | ||
| 448 | This affects View mode, etc. | ||
| 449 | |||
| 450 | ** The default value of `make-backup-file-name-function' is no longer nil. | ||
| 451 | Instead it defaults to a function that does what the nil value used to. | ||
| 452 | |||
| 453 | ** Help | ||
| 454 | |||
| 455 | *** The command `apropos-variable' is renamed to `apropos-user-option'. | ||
| 456 | `apropos-user-option' shows all user options, while `apropos-variable' | ||
| 457 | shows all variables. When called with a universal prefix argument, | ||
| 458 | the two commands swap their behaviors. When `apropos-do-all' is | ||
| 459 | non-nil, they output the same results. | ||
| 460 | |||
| 461 | *** The key `?' now describes prefix bindings, like `C-h'. | ||
| 462 | |||
| 463 | *** The command `describe-function' has been extended for EIEIO. | ||
| 464 | Running it on constructors will show a full description of the | ||
| 465 | generated class. For generic functions, it will show all | ||
| 466 | implementations together with links to the source. The old commands | ||
| 467 | `describe-class', `describe-constructor' and `describe-generic' were | ||
| 468 | removed. | ||
| 469 | |||
| 470 | *** The function `quail-help' is no longer an interactive command. | ||
| 471 | Use `C-h C-\' (`describe-input-method') instead. | ||
| 472 | |||
| 473 | ** Frame and window handling | ||
| 474 | |||
| 475 | *** New commands `toggle-frame-fullscreen' and `toggle-frame-maximized', | ||
| 476 | bound to <f11> and M-<f10>, respectively. | ||
| 477 | |||
| 478 | *** New hooks `focus-in-hook', `focus-out-hook'. | ||
| 479 | These are normal hooks run when an Emacs frame gains or loses input focus. | ||
| 480 | |||
| 481 | *** The function `window-in-direction' now takes additional arguments | ||
| 482 | for specifying a reference point, wrapping the selection around frame | ||
| 483 | borders, and specifying ways to select the minibuffer window. | ||
| 484 | |||
| 485 | *** Emacs can now change frame sizes in units of pixels, rather than | ||
| 486 | text rows or columns. When maximizing a frame or making it fullscreen, | ||
| 487 | remaining extra pixels are no longer given to the minibuffer, the rightmost | ||
| 488 | fringe, or other unusable space, but are distributed among the text | ||
| 489 | areas of the frame's windows. If the new option `frame-resize-pixelwise' | ||
| 490 | is non-nil, all frame size changes happen pixelwise and set the | ||
| 491 | corresponding size hints for the window manager. | ||
| 492 | |||
| 493 | *** Emacs can now change window sizes in units of pixels. | ||
| 494 | Mouse-dragging a mode line or window divider now changes the size of | ||
| 495 | adjacent windows pixelwise. If the new option `window-resize-pixelwise' | ||
| 496 | is non-nil, functions like `balance-windows-area' and `fit-window-to-buffer' | ||
| 497 | resize windows pixelwise. Most functions for changing or accessing | ||
| 498 | window sizes now have an additional argument that allows changes to apply, | ||
| 499 | or values to be returned, in pixels instead of lines/columns. | ||
| 500 | |||
| 501 | *** The functions `window-body-height' and `window-body-width' now never | ||
| 502 | count partially visible lines or columns if called with a nil PIXELWISE | ||
| 503 | argument. | ||
| 504 | |||
| 505 | *** Emacs can now draw dividers between adjacent windows. To put | ||
| 506 | dividers between side-by-side/vertically stacked windows customize the | ||
| 507 | frame parameters `right-divider-width' and `bottom-divider-width' to | ||
| 508 | some positive integer. You can drag dividers with the mouse (they show | ||
| 509 | a corresponding cursor when the mouse hovers over them). You can change | ||
| 510 | the appearance of dividers by customizing the faces `window-divider', | ||
| 511 | `window-divider-first-pixel', and `window-divider-last-pixel'. The last | ||
| 512 | two are useful to provide a 3D effect, or to better distinguish dividers | ||
| 513 | from surrounding display objects. | ||
| 514 | |||
| 515 | *** New functions to return the pixel sizes of window components, namely | ||
| 516 | `window-scroll-bar-width', `window-mode-line-height', | ||
| 517 | `window-header-line-height', `window-right-divider-width', and | ||
| 518 | `window-bottom-divider-width'. | ||
| 519 | |||
| 520 | *** The new function `window-text-pixel-size' returns the size of the | ||
| 521 | text of a window's buffer in pixels. This allows functions like | ||
| 522 | `fit-frame-to-buffer' and `fit-window-to-buffer' to accurately fit a | ||
| 523 | window to its buffer as it will be displayed. | ||
| 524 | |||
| 525 | *** `fit-window-to-buffer' can now resize windows in both dimensions. | ||
| 526 | This behavior is controlled by the new option | ||
| 527 | `fit-window-to-buffer-horizontally'. The new option | ||
| 528 | `fit-frame-to-buffer' allows you to fit the window's frame to its buffer. | ||
| 529 | |||
| 530 | *** `fit-frame-to-buffer' now fits frames in both dimensions. The new | ||
| 531 | options `fit-frame-to-buffer-margins' and `fit-frame-to-buffer-sizes' | ||
| 532 | control the size of the frame and its position on screen. | ||
| 533 | |||
| 534 | *** Temp Buffer Resize Mode can now adjust the height and width of | ||
| 535 | windows and frames. The new option `temp-buffer-max-width' allows you to | ||
| 536 | control the width of temporary buffer windows. Moreover, if the new | ||
| 537 | option `fit-frame-to-buffer' is non-nil and the buffer appears in the | ||
| 538 | root window of a frame, Temp Buffer Resize Mode will try to adjust the | ||
| 539 | width and/or height of the frame. | ||
| 540 | |||
| 541 | *** `split-window' is now a non-interactive function, not a command. | ||
| 542 | As a command, it was a special case of `C-x 2' (`split-window-below'), | ||
| 543 | and as such superfluous. After being reimplemented in Lisp, its | ||
| 544 | interactive form was mistakenly retained. | ||
| 545 | |||
| 546 | *** The functions `window-size' and `window-total-size' now have an | ||
| 547 | optional argument to return a rounded size value. | ||
| 548 | |||
| 549 | *** `window-state-put' now allows you to put a window state into internal | ||
| 550 | windows too. | ||
| 551 | |||
| 552 | *** New option `scroll-bar-adjust-thumb-portion'. | ||
| 553 | Available only on X, this option allows you to control over-scrolling | ||
| 554 | using the scroll bar (i.e., dragging the thumb down even when the end | ||
| 555 | of the buffer is visible). | ||
| 556 | |||
| 557 | *** New display actions functions for `display-buffer': | ||
| 558 | |||
| 559 | **** `display-buffer-at-bottom' chooses or creates a window at the | ||
| 560 | bottom of the selected frame. | ||
| 561 | |||
| 562 | **** `display-buffer-no-window' to not display the buffer in a window. | ||
| 563 | |||
| 564 | *** New display action alist entry `allow-no-window' to indicate the | ||
| 565 | caller of `display-buffer' is ready to handle the case of not displaying | ||
| 566 | the buffer in a window. | ||
| 567 | |||
| 568 | *** `display-buffer-in-previous-window' is now a member of | ||
| 569 | `display-buffer-fallback-action'. | ||
| 570 | |||
| 571 | ** Lisp evaluation | ||
| 572 | |||
| 573 | *** `eval-defun' on an already defined defcustom calls the :set function, | ||
| 574 | if there is one. | ||
| 575 | |||
| 576 | *** The commands `eval-expression' (`M-:'), `eval-last-sexp' (`C-x C-e'), | ||
| 577 | and `eval-print-last-sexp' (`C-j' in Lisp Interaction mode) can take a | ||
| 578 | zero prefix argument. This disables truncation of lists in the output, | ||
| 579 | equivalent to setting `(eval-expression-)print-length' and | ||
| 580 | `(eval-expression-)print-level' to nil. Additionally, it causes integers | ||
| 581 | to be printed in other formats (octal, hexadecimal, and character). | ||
| 582 | |||
| 583 | *** New hook `eval-expression-minibuffer-setup-hook' run by | ||
| 584 | `eval-expression' on entering the minibuffer. | ||
| 585 | |||
| 586 | ** `cache-long-line-scans' is now non-nil, and renamed to `cache-long-scans', | ||
| 587 | because it affects caching of paragraph scanning results as well. | ||
| 588 | There is no reason to set this to nil except for debugging purposes. | ||
| 589 | |||
| 590 | ** `emacs-bzr-version' has been renamed to `emacs-repository-version', | ||
| 591 | and works for git too, if you fetch the repository notes. | ||
| 592 | |||
| 593 | ** The default value of `comment-use-global-state' is now t, | ||
| 594 | and this variable has been marked obsolete. | ||
| 595 | |||
| 596 | ** `write-region-inhibit-fsync' now defaults to t in batch mode. | ||
| 597 | |||
| 598 | ** The option `set-mark-default-inactive' has been deleted. | ||
| 599 | This unfinished feature was introduced by accident in Emacs 23.1; | ||
| 600 | simply disabling Transient Mark mode does the same thing. | ||
| 601 | |||
| 602 | |||
| 603 | * Editing Changes in Emacs 24.4 | ||
| 604 | |||
| 605 | ** Indentation | ||
| 606 | |||
| 607 | *** `electric-indent-mode' is now enabled by default. | ||
| 608 | Typing RET reindents the current line and indents the new line. | ||
| 609 | `C-j' inserts a newline but does not indent. In some programming modes, | ||
| 610 | additional characters are electric (eg `{'). | ||
| 611 | |||
| 612 | *** New buffer-local `electric-indent-local-mode'. | ||
| 613 | |||
| 614 | *** The behavior of `C-x TAB' (`indent-rigidly') has changed. | ||
| 615 | When invoked without a prefix argument, it now activates a transient | ||
| 616 | mode in which typing <left>, <right>, <S-left>, and <S-right> adjusts | ||
| 617 | the text indentation in the region. Typing any other key resumes | ||
| 618 | normal editing behavior. | ||
| 619 | |||
| 620 | *** `tab-stop-list' is now implicitly extended to infinity by repeating | ||
| 621 | the last step. Its default value is changed to nil, which means a tab | ||
| 622 | stop every `tab-width' columns. | ||
| 623 | |||
| 624 | ** Uniquify is enabled by default, with `post-forward-angle-brackets' style. | ||
| 625 | In other words, if you visit two files that have the same base name, | ||
| 626 | then rather than creating buffers basename and basename<2>, | ||
| 627 | Emacs uses basename<dirA> and basename<dirB>. To change this, | ||
| 628 | customize `uniquify-buffer-name-style'. Set it to nil for the old behavior. | ||
| 629 | |||
| 630 | ** New command `C-x SPC' (`rectangle-mark-mode') makes a rectangular region. | ||
| 631 | Most commands are still unaware of it, but kill/yank do work on the rectangle. | ||
| 632 | |||
| 633 | ** New option `visual-order-cursor-movement'. | ||
| 634 | If this is non-nil, cursor motion with arrow keys will follow the | ||
| 635 | visual order of characters on the screen: <left> always moves to the | ||
| 636 | left, <right> always moves to the right, disregarding the surrounding | ||
| 637 | bidirectional context. | ||
| 638 | |||
| 639 | ** New command `delete-duplicate-lines'. | ||
| 640 | This searches the region for identical lines, and removes all but one | ||
| 641 | copy of each repeated line. The lines need not be sorted. | ||
| 642 | |||
| 643 | ** New command `cycle-spacing' acts like a smarter `just-one-space'. | ||
| 644 | When called in succession, it cycles between spacing conventions: | ||
| 645 | one space, no spaces, original spacing. | ||
| 646 | |||
| 647 | ** `blink-matching-paren' now only highlights the matching open-paren | ||
| 648 | by default, instead of moving the cursor. Set this variable to `jump' to | ||
| 649 | restore the old behavior. | ||
| 650 | |||
| 651 | ** The new function `fill-single-char-nobreak-p' can stop fill from breaking | ||
| 652 | a line after a one-letter word, which is an error in some typographical | ||
| 653 | conventions. To use it, add it to the `fill-nobreak-predicate' hook. | ||
| 654 | |||
| 655 | ** Registers | ||
| 656 | |||
| 657 | *** All interactive commands that read a register (`copy-to-register', etc.) | ||
| 658 | now display a temporary window after `register-preview-delay' seconds | ||
| 659 | that summarizes existing registers. To disable this, set that option to nil. | ||
| 660 | Interactive commands that read registers and want to make use of this | ||
| 661 | should use `register-read-with-preview' to read register names. | ||
| 662 | |||
| 663 | *** New command `frameset-to-register' bound to `C-x r f', replacing | ||
| 664 | `frame-configuration-to-register'. It offers similar functionality, | ||
| 665 | plus enhancements like the ability to restore deleted frames. | ||
| 666 | (`frame-configuration-to-register' still exists, but no longer has a | ||
| 667 | key binding.) | ||
| 668 | |||
| 669 | *** New command `C-x C-k x' (`kmacro-to-register') stores keyboard | ||
| 670 | macros in registers. | ||
| 671 | |||
| 672 | |||
| 673 | * Changes in Specialized Modes and Packages in Emacs 24.4 | ||
| 674 | |||
| 675 | ** Backtrace and debugger | ||
| 676 | |||
| 677 | *** New Lisp debugger command `v' (`debugger-toggle-locals') toggles the | ||
| 678 | display of local variables of the current stack frame. | ||
| 679 | |||
| 680 | *** The Lisp debugger's `e' command (`debugger-eval-expression') now includes | ||
| 681 | the lexical environment when evaluating the code in the context at point | ||
| 682 | (and so allows you to access lexical variables). | ||
| 683 | |||
| 684 | *** New minor mode `jit-lock-debug-mode' helps you debug code run via JIT Lock. | ||
| 685 | |||
| 686 | ** Battery information can now be retrieved from BSD's `apm' utility. | ||
| 687 | |||
| 688 | ** In the Buffer Menu, `M-s a C-o' shows matches for a regexp in marked buffers. | ||
| 689 | |||
| 690 | ** Calc | ||
| 691 | |||
| 692 | *** Calc by default now uses the Gregorian calendar for all dates, and | ||
| 693 | uses January 1, 1 AD as its day number 1. Previously Calc used the | ||
| 694 | Julian calendar for dates before September 14, 1752, and it used | ||
| 695 | December 31, 1 BC as its day number 1; the new scheme is more | ||
| 696 | consistent with Calendar's calendrical system and day numbering. | ||
| 697 | |||
| 698 | *** The new option `calc-gregorian-switch' lets you configure if | ||
| 699 | (and when) Calc switches from the Julian to the Gregorian calendar. | ||
| 700 | |||
| 701 | *** Support for ISO 8601 dates. | ||
| 702 | |||
| 703 | ** Calendar and Diary | ||
| 704 | |||
| 705 | *** New faces `calendar-weekday-header', `calendar-weekend-header', | ||
| 706 | and `calendar-month-header'. | ||
| 707 | |||
| 708 | *** New option `calendar-day-header-array'. | ||
| 709 | |||
| 710 | *** New variable `diary-from-outlook-function', used by the command | ||
| 711 | `diary-from-outlook'. | ||
| 712 | |||
| 713 | *** The variable `calendar-font-lock-keywords' is obsolete. | ||
| 714 | |||
| 715 | ** CEDET | ||
| 716 | |||
| 717 | *** EDE | ||
| 718 | |||
| 719 | **** The cpp-root project now supports executing a compile command. | ||
| 720 | It can be set through the new :compile-command slot or the | ||
| 721 | buffer-local variable `compile-command'. | ||
| 722 | |||
| 723 | **** Better selection of include directories for the 'linux' project. | ||
| 724 | Include directories now support out-of-tree build directories and | ||
| 725 | target architecture auto-detection. | ||
| 726 | |||
| 727 | *** Semantic | ||
| 728 | |||
| 729 | **** Improved detection of used namespaces in current scope in C++. | ||
| 730 | |||
| 731 | **** Parsing of default values for variables and function arguments in C/C++. | ||
| 732 | They are also displayed by the summarize feature in the mode line. | ||
| 733 | |||
| 734 | **** Improved parsing of function pointers in C/C++. | ||
| 735 | This also includes parsing of function pointers as function arguments. | ||
| 736 | |||
| 737 | **** Parsing of C/C++ preprocessor macros that open new scope. | ||
| 738 | For example, this enables parsing of macros that open new namespaces. | ||
| 739 | |||
| 740 | **** Support for 'this' pointer in inline member functions in C++. | ||
| 741 | |||
| 742 | ** CFEngine mode | ||
| 743 | |||
| 744 | *** Support for completion, ElDoc, and Flycheck has been added. | ||
| 745 | |||
| 746 | *** The current CFEngine syntax is parsed from "cf-promises -s json". | ||
| 747 | There is a fallback syntax available if you don't have cf-promises or | ||
| 748 | if your version doesn't support that option. See option `cfengine-cf-promises'. | ||
| 749 | |||
| 750 | ** cl-lib | ||
| 751 | |||
| 752 | *** New macro `cl-tagbody'. | ||
| 753 | This executes statements while allowing for control transfer to labels. | ||
| 754 | |||
| 755 | *** letf is now just an alias for cl-letf. | ||
| 756 | |||
| 757 | ** CUA mode | ||
| 758 | |||
| 759 | *** CUA mode now uses `delete-selection-mode' and `shift-select-mode'. | ||
| 760 | Hence, you can now enable it independently from those modes, and from | ||
| 761 | `transient-mark-mode'. | ||
| 762 | |||
| 763 | *** `cua-highlight-region-shift-only' is now obsolete. | ||
| 764 | You can disable `transient-mark-mode' to get the same result. | ||
| 765 | |||
| 766 | *** CUA's rectangles can now be used without CUA by calling the command | ||
| 767 | `cua-rectangle-mark-mode'. | ||
| 768 | |||
| 769 | ** Delete Selection mode can now be used without Transient Mark mode. | ||
| 770 | |||
| 771 | ** Desktop | ||
| 772 | |||
| 773 | *** `desktop-save-mode' by default now auto-saves an existing desktop file | ||
| 774 | after `desktop-auto-save-timeout'. To disable this, customize that option | ||
| 775 | to nil (or zero). | ||
| 776 | |||
| 777 | *** Desktop now saves and restores the frame/window configuration. | ||
| 778 | To disable this, set `desktop-restore-frames' to nil. | ||
| 779 | See also related options `desktop-restore-reuses-frames', | ||
| 780 | `desktop-restore-in-current-display', and `desktop-restore-forces-onscreen'. | ||
| 781 | |||
| 782 | ** New Dired minor mode `dired-hide-details-mode' toggles whether details, | ||
| 783 | such as file ownership or permissions, are visible in Dired buffers. | ||
| 784 | See the new options `dired-hide-details-hide-symlink-targets' and | ||
| 785 | `dired-hide-details-hide-information-lines' for customizing what to hide. | ||
| 786 | |||
| 787 | ** You can enable ElDoc inside the `eval-expression' minibuffer with: | ||
| 788 | (add-hook 'eval-expression-minibuffer-setup-hook 'eldoc-mode) | ||
| 789 | The results display in the mode line. | ||
| 790 | |||
| 791 | ** Electric Pair mode | ||
| 792 | |||
| 793 | *** New option `electric-pair-preserve-balance', enabled by default. | ||
| 794 | If non-nil, pairing/skipping only kicks in when that help the balance | ||
| 795 | of parentheses and quotes; i.e., the buffer should end up at least as | ||
| 796 | balanced as before. | ||
| 797 | |||
| 798 | You can further control this behavior by adjusting the predicates | ||
| 799 | stored in `electric-pair-inhibit-predicate' and `electric-pair-skip-self'. | ||
| 800 | |||
| 801 | *** New option `electric-pair-delete-adjacent-pairs', enabled by default. | ||
| 802 | In `electric-pair-mode', the commands `backward-delete-char' and | ||
| 803 | `backward-delete-char-untabify' are now bound to electric variants | ||
| 804 | that delete the closer when invoked between adjacent pairs. | ||
| 805 | |||
| 806 | *** New option `electric-pair-open-newline-between-pairs', enabled by default. | ||
| 807 | In `electric-pair-mode', inserting a newline between adjacent pairs | ||
| 808 | opens an extra newline after point, which is indented if | ||
| 809 | `electric-indent-mode' is also set. | ||
| 810 | |||
| 811 | *** New option `electric-pair-skip-whitespace', enabled by default. | ||
| 812 | This controls if skipping over closing delimiters should jump over any | ||
| 813 | whitespace slack. Setting it to `chomp' makes it delete this | ||
| 814 | whitespace. See also the variable `electric-pair-skip-whitespace-chars'. | ||
| 815 | |||
| 816 | *** New variables control the pairing in strings and comments. | ||
| 817 | You can customize `electric-pair-text-pairs' and | ||
| 818 | `electric-pair-text-syntax-table' to tweak pairing behavior inside | ||
| 819 | strings and comments. | ||
| 820 | |||
| 821 | ** New EPA option `epa-mail-aliases'. | ||
| 822 | You can set this to a list of email address aliases that `epa-mail-encrypt' | ||
| 823 | should use to find keys. | ||
| 824 | |||
| 825 | ** New ERC option `erc-accidental-paste-threshold-seconds'. | ||
| 826 | If set to a number, this can be used to avoid accidentally pasting large | ||
| 827 | amounts of data into the ERC input. | ||
| 828 | |||
| 829 | ** New ERT macro `skip-unless' allows skipping ERT tests. | ||
| 830 | |||
| 831 | ** Eshell | ||
| 832 | |||
| 833 | *** `eshell' now supports visual subcommands and options. | ||
| 834 | Eshell has been able to handle "visual" commands (interactive, | ||
| 835 | non-line oriented commands such as top that require display | ||
| 836 | capabilities not provided by eshell) by running them in an Emacs | ||
| 837 | terminal emulator. See `eshell-visual-commands'. | ||
| 838 | |||
| 839 | This feature has been extended to subcommands and options that make a | ||
| 840 | usually line-oriented command a visual command. Typical examples are | ||
| 841 | "git log" and "git <command> --help", which display their output in a | ||
| 842 | pager by default. See `eshell-visual-subcommands' and `eshell-visual-options'. | ||
| 843 | |||
| 844 | *** New Eshell-Tramp module. | ||
| 845 | External su and sudo commands are now the default; the internal, | ||
| 846 | Tramp-using variants can still be used by enabling the eshell-tramp module. | ||
| 847 | |||
| 848 | ** New F90 mode option `f90-smart-end-names'. | ||
| 849 | |||
| 850 | ** New option `gnutls-verify-error', if non-nil, means that Emacs | ||
| 851 | should reject SSL/TLS certificates that GnuTLS determines as invalid. | ||
| 852 | (This option defaults to nil at present, but this is expected to change | ||
| 853 | in a future release.) | ||
| 854 | |||
| 855 | ** Hi-Lock | ||
| 856 | |||
| 857 | *** New global command `M-s h .' (`highlight-symbol-at-point') highlights | ||
| 858 | the symbol near point. | ||
| 859 | |||
| 860 | *** New option `hi-lock-auto-select-face'. When non-nil, hi-lock commands | ||
| 861 | will cycle through faces in `hi-lock-face-defaults' without prompting. | ||
| 862 | |||
| 863 | ** Icomplete is now more similar to Ido. | ||
| 864 | |||
| 865 | *** Icomplete by default now applies to all forms of minibuffer completion. | ||
| 866 | The variable `icomplete-with-completion-tables' (now a user option) | ||
| 867 | controls this. To restore the old behavior, set it back to | ||
| 868 | '(internal-complete-buffer). | ||
| 869 | |||
| 870 | *** You can navigate through and select completions using the keys | ||
| 871 | from `icomplete-minibuffer-map'. | ||
| 872 | |||
| 873 | *** The string that separates potential completions is now a customizable | ||
| 874 | option (`icomplete-separator'). The default is " | " rather than ",". | ||
| 875 | |||
| 876 | *** New face `icomplete-first-match'; and new options | ||
| 877 | `icomplete-hide-common-prefix' and `icomplete-show-matches-on-no-input'. | ||
| 878 | |||
| 879 | *** The option `icomplete-show-key-bindings' has been removed. | ||
| 880 | |||
| 881 | ** Ido | ||
| 882 | |||
| 883 | *** An Ido user manual is now included. | ||
| 884 | |||
| 885 | *** The option `ido-use-virtual-buffers' can now take the value `auto'. | ||
| 886 | This means to use virtual buffers if the current ido input does not match | ||
| 887 | an existing buffer. | ||
| 888 | |||
| 889 | *** The variable `ido-decorations' can optionally have two new elements, | ||
| 890 | which are the brackets to use around the sole remaining completion. | ||
| 891 | |||
| 892 | ** Image mode | ||
| 893 | |||
| 894 | *** New commands `n' (`image-next-file') and `p' (`image-previous-file') | ||
| 895 | visit the next image file and the previous image file in the same | ||
| 896 | directory, respectively. | ||
| 897 | |||
| 898 | *** New commands to show specific frames of multi-frame images. | ||
| 899 | `f' (`image-next-frame') and `b' (`image-previous-frame') visit the | ||
| 900 | next or previous frame. `F' (`image-goto-frame') shows a specific frame. | ||
| 901 | |||
| 902 | *** New commands to speed up, slow down, or reverse animation. | ||
| 903 | `a +' (`image-increase-speed') and `a -' (`image-decrease-speed') to | ||
| 904 | speed up and slow down the animation. `a r' (`image-reverse-speed') | ||
| 905 | to reverse it and `a 0' (`image-reset-speed') to reset it. | ||
| 906 | |||
| 907 | *** The command `image-mode-fit-frame' deletes other windows. | ||
| 908 | When toggling, it restores the frame's previous window configuration. | ||
| 909 | It also has an optional frame argument, which can be used by Lisp | ||
| 910 | callers to fit the image to a frame other than the selected frame. | ||
| 911 | |||
| 912 | ** New Imenu option `imenu-generic-skip-comments-and-strings'. | ||
| 913 | |||
| 914 | ** Info | ||
| 915 | |||
| 916 | *** New Info face `info-index-match', used to highlight matches in index | ||
| 917 | entries displayed by `Info-index-next', `Info-virtual-index' and | ||
| 918 | `info-apropos'. | ||
| 919 | |||
| 920 | *** The Info-edit command is obsolete. Editing Info nodes by hand | ||
| 921 | has not been relevant for some time. | ||
| 922 | |||
| 923 | ** JS Mode | ||
| 924 | |||
| 925 | *** New option `js-switch-indent-offset'. | ||
| 926 | |||
| 927 | *** Better indentation of multiple-variable declarations. | ||
| 928 | If a declaration spans several lines, variables on the following lines | ||
| 929 | are lined up to the first one. | ||
| 930 | |||
| 931 | *** Recognition and better indentation of continuations in array comprehensions. | ||
| 932 | |||
| 933 | ** MH-E has been updated to version 8.6 - see separate MH-E-NEWS file. | ||
| 934 | |||
| 935 | ** Octave mode | ||
| 936 | |||
| 937 | *** Font locking for Texinfo comments and new keywords. | ||
| 938 | |||
| 939 | *** Completion in Octave file buffers. | ||
| 940 | |||
| 941 | *** ElDoc support. | ||
| 942 | |||
| 943 | *** Jump to definition. | ||
| 944 | |||
| 945 | *** Documentation lookup/search. | ||
| 946 | |||
| 947 | ** OPascal mode is the new name for Delphi mode | ||
| 948 | |||
| 949 | *** All delphi-* variables and functions have been renamed to opascal-*. | ||
| 950 | Obsolete aliases exist for those likely to have been used externally. | ||
| 951 | |||
| 952 | *** The option `delphi-newline-always-indents' has been removed. | ||
| 953 | Use `electric-indent-mode' instead. | ||
| 954 | |||
| 955 | *** The TAB key runs the standard `indent-for-tab-command', not `delphi-tab'. | ||
| 956 | |||
| 957 | ** Package | ||
| 958 | |||
| 959 | *** The package library now supports digital signing of packages. | ||
| 960 | Maintainers of package archives should consider signing their packages | ||
| 961 | to enhance security. | ||
| 962 | |||
| 963 | **** If the user option `package-check-signature' is non-nil, | ||
| 964 | Emacs tries to check package signatures at install time. | ||
| 965 | The value `allow-unsigned' allows installation of unsigned packages. | ||
| 966 | |||
| 967 | **** The user option `package-unsigned-archives' lists archives where | ||
| 968 | Emacs will not try to check signatures. | ||
| 969 | |||
| 970 | *** New option `package-pinned-packages'. This is useful if you have multiple | ||
| 971 | archives enabled, with more than one offering a given package that you want. | ||
| 972 | |||
| 973 | *** In the `list-packages' buffer, you can use `f' (`package-menu-filter') | ||
| 974 | to filter the list of packages by a keyword. | ||
| 975 | |||
| 976 | *** In the `describe-package' buffer, there are now buttons listing the | ||
| 977 | keywords related to the package. Click on a button to see other packages | ||
| 978 | related to that keyword. | ||
| 979 | |||
| 980 | *** The format of `archive-contents' files, generated by package | ||
| 981 | repositories, has changed to allow a new (fifth) element in the data | ||
| 982 | vectors, containing an associative list with extra properties. | ||
| 983 | (For example, `describe-package' uses the `:url' extra property to | ||
| 984 | display a "Homepage" header.) | ||
| 985 | |||
| 986 | ** In Prolog mode, `prolog-use-smie' has been removed, | ||
| 987 | along with the non-SMIE indentation code. | ||
| 988 | |||
| 989 | ** Python mode | ||
| 990 | |||
| 991 | *** Out of the box support for CPython, iPython and readline based shells. | ||
| 992 | **** `python-shell-completion-module-string-code' is no longer used. | ||
| 993 | |||
| 994 | *** Automatic shell prompt detection. New user options: | ||
| 995 | **** `python-shell-interpreter-interactive-arg'. | ||
| 996 | **** `python-shell-prompt-detect-enabled'. | ||
| 997 | **** `python-shell-prompt-detect-failure-warning'. | ||
| 998 | **** `python-shell-prompt-input-regexps'. | ||
| 999 | **** `python-shell-prompt-output-regexps'. | ||
| 1000 | |||
| 1001 | *** Python shell support for remote hosts via tramp. | ||
| 1002 | |||
| 1003 | *** Correct display of line numbers for code sent to the Python shell. | ||
| 1004 | |||
| 1005 | ** Remember | ||
| 1006 | |||
| 1007 | *** The new command `remember-notes' creates a buffer that is saved on exit. | ||
| 1008 | You can use it as a more permanent *scratch* buffer. | ||
| 1009 | |||
| 1010 | *** Remember can now store notes in separate files. | ||
| 1011 | To use this, add `remember-store-in-files' to the `remember-handler-functions' | ||
| 1012 | option. The files are saved in `remember-data-directory' using | ||
| 1013 | names specified by `remember-directory-file-name-format'. | ||
| 1014 | |||
| 1015 | ** Rmail | ||
| 1016 | |||
| 1017 | *** Customize `rmail-mbox-format' to influence some minor aspects of | ||
| 1018 | how Rmail displays non-MIME messages. | ||
| 1019 | |||
| 1020 | *** The `unrmail' command now converts from BABYL to mboxrd format, | ||
| 1021 | rather than mboxo. Customize `unrmail-mbox-format' to change this. | ||
| 1022 | |||
| 1023 | ** Ruby mode | ||
| 1024 | |||
| 1025 | *** Improved syntax highlighting and indentation. | ||
| 1026 | |||
| 1027 | *** New `electric-indent-mode' integration. | ||
| 1028 | |||
| 1029 | *** New option `ruby-encoding-magic-comment-style'. | ||
| 1030 | |||
| 1031 | *** New option `ruby-custom-encoding-magic-comment-template'. | ||
| 1032 | |||
| 1033 | *** New option `ruby-align-to-stmt-keywords'. | ||
| 1034 | |||
| 1035 | *** New option `ruby-align-chained-calls'. | ||
| 1036 | |||
| 1037 | *** More Ruby file types have been added to `auto-mode-alist'. | ||
| 1038 | |||
| 1039 | ** Search and Replace | ||
| 1040 | |||
| 1041 | *** New global command `M-s .' (`isearch-forward-symbol-at-point') | ||
| 1042 | starts a symbol (identifier) incremental search forward with the | ||
| 1043 | symbol found near point added to the search string initially. | ||
| 1044 | |||
| 1045 | *** `C-x 8 RET' in Isearch mode reads a character by its Unicode name | ||
| 1046 | and adds it to the search string. | ||
| 1047 | |||
| 1048 | *** `M-s i' in Isearch mode toggles whether search matches invisible text. | ||
| 1049 | |||
| 1050 | *** `query-replace' skips invisible text when `search-invisible' is nil, | ||
| 1051 | and opens overlays with hidden text when `search-invisible' is `open'. | ||
| 1052 | |||
| 1053 | *** A negative prefix argument of replacement commands replaces backward. | ||
| 1054 | `M-- M-%' replaces a string backward, `M-- C-M-%' replaces a regexp | ||
| 1055 | backward, `M-s w words M-- M-%' replaces a sequence of words backward. | ||
| 1056 | |||
| 1057 | *** By default, prefix arguments do not now terminate Isearch mode. | ||
| 1058 | Set `isearch-allow-prefix' to nil to restore the old behavior. | ||
| 1059 | |||
| 1060 | *** More Isearch commands accept prefix arguments, namely | ||
| 1061 | `isearch-printing-char', `isearch-quote-char', `isearch-yank-word', | ||
| 1062 | `isearch-yank-line'. | ||
| 1063 | |||
| 1064 | *** Word search now matches whitespace at the beginning/end | ||
| 1065 | of the search string if it contains leading/trailing whitespace. | ||
| 1066 | In an incremental word search or when using a non-nil LAX argument | ||
| 1067 | of `word-search-regexp', the lax matching can also match part of | ||
| 1068 | the first word (in addition to the lax matching of the last word). | ||
| 1069 | The same rules are now applied to the symbol search, with the difference | ||
| 1070 | that it matches symbols, and non-symbol characters between symbols. | ||
| 1071 | |||
| 1072 | ** New SES command `ses-rename-cell' allows assignment of names to SES cells. | ||
| 1073 | |||
| 1074 | ** The shell.el option `explicit-bash-args' includes --noediting by default. | ||
| 1075 | All non-ancient Bash versions support this option. | ||
| 1076 | |||
| 1077 | ** Shell Script mode | ||
| 1078 | |||
| 1079 | *** The SMIE indentation engine is now used by default - see `sh-use-smie'. | ||
| 1080 | |||
| 1081 | *** `sh-mode' now has its own setting for `add-log-current-defun-function'. | ||
| 1082 | |||
| 1083 | ** SMIE | ||
| 1084 | |||
| 1085 | *** You can customize the SMIE indentation of a mode via `smie-config'. | ||
| 1086 | The command `smie-config-guess' can help you derive the appropriate | ||
| 1087 | indentation settings, if you provide it with an indented sample file. | ||
| 1088 | Use `smie-config-save' to save the result. | ||
| 1089 | |||
| 1090 | *** You can customize the SMIE indentation of a file by adding an entry to | ||
| 1091 | the file's local variables of the form: `eval: (smie-config-local '(RULES))'. | ||
| 1092 | |||
| 1093 | *** New commands `smie-config-show-indent' and `smie-config-set-indent'. | ||
| 1094 | |||
| 1095 | ** SQL mode | ||
| 1096 | |||
| 1097 | *** Improved login monitoring and appropriate response to login failures. | ||
| 1098 | New variable `sql-login-delay' defines maximum wait time for a connection. | ||
| 1099 | |||
| 1100 | *** Oracle support. | ||
| 1101 | SQL*Plus script placeholders are properly highlighted and identified | ||
| 1102 | in `sql-placeholders-filter'. When starting SQL*Plus, `sql-oracle-options' | ||
| 1103 | are passed before the logon parameter, as required. The default now | ||
| 1104 | includes `-L', to limit the number of logon attempts per invocation. | ||
| 1105 | |||
| 1106 | ** New Term mode option `term-suppress-hard-newline'. | ||
| 1107 | |||
| 1108 | ** Todo mode has been rewritten and enhanced. | ||
| 1109 | The Todo mode user manual describes all commands and most user | ||
| 1110 | options. To support some of these features, a new file format is | ||
| 1111 | used, which is incompatible with the old format; however, you can | ||
| 1112 | convert old todo and done item files to the new format on initializing | ||
| 1113 | the first new todo file, or at any later time with the provided | ||
| 1114 | conversion command. The previous version of todo-mode.el has been | ||
| 1115 | renamed to otodo-mode.el and is now obsolete. New features include: | ||
| 1116 | |||
| 1117 | *** Support for multiple todo files and archive files of done items. | ||
| 1118 | |||
| 1119 | *** Renaming, reordering, moving, merging, and deleting categories. | ||
| 1120 | |||
| 1121 | *** Sortable tabular summaries of categories and the item types they contain. | ||
| 1122 | |||
| 1123 | *** Cross-category lists of items filtered by specific criteria. | ||
| 1124 | |||
| 1125 | *** More fine-grained interaction with the Emacs diary, by being able to | ||
| 1126 | decide for each todo item whether it appears in the Fancy Diary display. | ||
| 1127 | |||
| 1128 | *** Highly flexible new item insertion and item editing. | ||
| 1129 | |||
| 1130 | *** Moving items between categories, storing done items in their category | ||
| 1131 | or in archive files, undoing or unarchiving done items. | ||
| 1132 | |||
| 1133 | *** Reprioritizing items by inputting a numerical priority. | ||
| 1134 | |||
| 1135 | *** Extensive customizability of operation and display, including many faces. | ||
| 1136 | |||
| 1137 | ** Trace | ||
| 1138 | |||
| 1139 | *** `trace-function' and `trace-function-background' no longer prompt for | ||
| 1140 | the output buffer. Unless you use a prefix argument, they output to | ||
| 1141 | `trace-buffer'. | ||
| 1142 | |||
| 1143 | *** With a prefix argument, `trace-function' and `trace-function-background' | ||
| 1144 | will prompt for a "context". This is a Lisp expression, whose value at the | ||
| 1145 | time the function is entered/exited is printed along with the function's | ||
| 1146 | name and arguments. | ||
| 1147 | |||
| 1148 | ** Tramp | ||
| 1149 | |||
| 1150 | *** New connection method "adb", which allows to access Android | ||
| 1151 | devices by the Android Debug Bridge. The variable `tramp-adb-program' | ||
| 1152 | can be used to adapt the path of the "adb" program, if needed. | ||
| 1153 | |||
| 1154 | *** Handlers for `file-acl' and `set-file-acl' for remote machines | ||
| 1155 | that support POSIX ACLs. | ||
| 1156 | |||
| 1157 | *** Handlers for `file-notify-add-watch' and `file-notify-rm-watch' | ||
| 1158 | for remote machines that support filesystem notifications. | ||
| 1159 | |||
| 1160 | *** The experimental url syntax for remote file names has been removed. | ||
| 1161 | |||
| 1162 | *** The connection methods "plink1", "ssh1", "ssh2", "scp1", "scp2", | ||
| 1163 | "scpc" and "rsyncc" are discontinued. The ssh option | ||
| 1164 | "ControlMaster=auto" is set automatically in all ssh-based methods, | ||
| 1165 | when possible. See `tramp-use-ssh-controlmaster-options'. | ||
| 1166 | |||
| 1167 | ** New URL command `url-cookie-list' displays the current cookies, | ||
| 1168 | and allows you to interactively remove cookies. | ||
| 1169 | |||
| 1170 | ** VC and related modes | ||
| 1171 | |||
| 1172 | *** In VC directory mode, `D' displays diffs between VC-controlled | ||
| 1173 | whole tree revisions. | ||
| 1174 | |||
| 1175 | *** In VC directory mode, `L' lists the change log for the current VC | ||
| 1176 | controlled tree in a window. | ||
| 1177 | |||
| 1178 | *** In VC directory mode, `I' shows a log of changes that will be | ||
| 1179 | received with a pull operation. | ||
| 1180 | |||
| 1181 | *** `C-x v G' (globally) and `G' (in VC directory mode) ignores a file | ||
| 1182 | under current version control system. When called with a prefix | ||
| 1183 | argument, you can remove a file from the ignored file list. | ||
| 1184 | |||
| 1185 | ** VHDL mode | ||
| 1186 | |||
| 1187 | *** New options: `vhdl-actual-generic-name', `vhdl-beautify-options'. | ||
| 1188 | |||
| 1189 | *** New commands: `vhdl-fix-statement-region', `vhdl-fix-statement-buffer'. | ||
| 1190 | |||
| 1191 | ** The Woman commands `woman-default-faces' and `woman-monochrome-faces' | ||
| 1192 | are obsolete. Customize the `woman-*' faces instead. | ||
| 1193 | |||
| 1194 | ** More packages look for ~/.emacs.d/<foo> additionally to ~/.<foo>. | ||
| 1195 | Affected files: | ||
| 1196 | ~/.emacs.d/timelog replaces ~/.timelog | ||
| 1197 | ~/.emacs.d/vip replaces ~/.vip | ||
| 1198 | ~/.emacs.d/viper replaces ~/.viper | ||
| 1199 | ~/.emacs.d/ido.last replaces ~/.ido.last | ||
| 1200 | ~/.emacs.d/kkcrc replaces ~/.kkcrc | ||
| 1201 | ~/.emacs.d/quickurls replaces ~/.quickurls | ||
| 1202 | ~/.emacs.d/idlwave/ replaces ~/.idlwave/ | ||
| 1203 | ~/.emacs.d/bdfcache.el replaces ~/.bdfcache.el | ||
| 1204 | ~/.emacs.d/places replaces ~/.emacs-places | ||
| 1205 | ~/.emacs.d/shadows replaces ~/.shadows | ||
| 1206 | ~/.emacs.d/shadow_todo replaces ~/.shadow_todo | ||
| 1207 | ~/.emacs.d/strokes replaces ~/.strokes | ||
| 1208 | ~/.emacs.d/notes replaces ~/.notes | ||
| 1209 | ~/.emacs.d/type-break replaces ~/.type-break | ||
| 1210 | Also the following files used by the now obsolete otodo-mode.el: | ||
| 1211 | ~/.emacs.d/todo-do replaces ~/.todo-do | ||
| 1212 | ~/.emacs.d/todo-done replaces ~/.todo-done | ||
| 1213 | ~/.emacs.d/todo-top replaces ~/.todo-top | ||
| 1214 | |||
| 1215 | ** Obsolete packages | ||
| 1216 | |||
| 1217 | *** iswitchb.el; use icomplete-mode. | ||
| 1218 | |||
| 1219 | *** longlines.el; use visual-line-mode. | ||
| 1220 | |||
| 1221 | *** meese.el. | ||
| 1222 | |||
| 1223 | *** sup-mouse.el. | ||
| 1224 | |||
| 1225 | *** terminal.el; use term.el instead. | ||
| 1226 | |||
| 1227 | *** the old version of todo-mode.el (renamed to otodo-mode.el). | ||
| 1228 | |||
| 1229 | *** xesam.el (owing to the cancellation of the XESAM project). | ||
| 1230 | |||
| 1231 | *** yow.el; use fortune.el or cookie1.el instead. | ||
| 1232 | |||
| 1233 | |||
| 1234 | * New Modes and Packages in Emacs 24.4 | ||
| 1235 | |||
| 1236 | ** New package eww.el provides a built-in web browser. | ||
| 1237 | This requires Emacs to have been compiled with libxml2 support. | ||
| 1238 | |||
| 1239 | ** New package nadvice.el offers lighter-weight advice facilities. | ||
| 1240 | It is layered as: | ||
| 1241 | |||
| 1242 | *** `add-function'/`remove-function', which can be used to add/remove code on | ||
| 1243 | any function-carrying place, such as process filters or `<foo>-function' hooks. | ||
| 1244 | |||
| 1245 | *** `advice-add'/`advice-remove' to add/remove a piece of advice on a named | ||
| 1246 | function, much like `defadvice' does. | ||
| 1247 | |||
| 1248 | ** New package frameset.el provides a set of operations to save a frameset | ||
| 1249 | (the state of all or a subset of the existing frames and windows, somewhat | ||
| 1250 | similar to a frame configuration), both in-session and persistently, and | ||
| 1251 | restore it at some point in the future. | ||
| 1252 | |||
| 1253 | ** New package filenotify.el provides an interface for file system | ||
| 1254 | notifications. It requires that Emacs be compiled with one of the | ||
| 1255 | low-level libraries gfilenotify.c, inotify.c or w32notify.c. | ||
| 1256 | |||
| 1257 | ** New minor modes `prettify-symbols-mode' and `global-prettify-symbols-mode' | ||
| 1258 | display specified symbols as composed characters. E.g., in Emacs Lisp mode, | ||
| 1259 | this replaces the string "lambda" with the Greek lambda character. | ||
| 1260 | |||
| 1261 | ** New minor mode `superword-mode', which overrides the default word motion | ||
| 1262 | commands to treat "symbol_words" as a single word, similar to what | ||
| 1263 | `subword-mode' does. | ||
| 1264 | |||
| 1265 | |||
| 1266 | * Incompatible Lisp Changes in Emacs 24.4 | ||
| 1267 | |||
| 1268 | ** The default file coding for Emacs Lisp files is now utf-8. | ||
| 1269 | (See `file-coding-system-alist'.) In most cases, this change is | ||
| 1270 | transparent, but files that contain unusual characters without | ||
| 1271 | specifying an explicit coding system may fail to load with obscure | ||
| 1272 | errors. You should either convert them to utf-8 or add an explicit | ||
| 1273 | `coding:' cookie. | ||
| 1274 | |||
| 1275 | ** Default process filters and sentinels are not nil any more. | ||
| 1276 | Instead they default to a function that does what the nil value used to do. | ||
| 1277 | |||
| 1278 | ** Overlay priority does not have to be nil or a non-negative integer. | ||
| 1279 | Overlay priority can be other kinds of Lisp objects. We didn't yet | ||
| 1280 | decide whether other types of values are stable enough, and therefore | ||
| 1281 | don't feel it's right to document them. For now, don't assume in your | ||
| 1282 | code that the values of overlay priority can only be either nil or an | ||
| 1283 | integer, always test them with an appropriate predicate to be one or | ||
| 1284 | the other. If you need to sort arbitrary overlays into priority | ||
| 1285 | order, `overlays-at' can now optionally do this. | ||
| 1286 | You should still only specify integer priorities on overlays you create. | ||
| 1287 | |||
| 1288 | ** The cars of the elements in `interpreter-mode-alist' are now | ||
| 1289 | treated as regexps rather than literal strings. | ||
| 1290 | |||
| 1291 | ** `overriding-terminal-local-map' no longer replaces the local keymaps. | ||
| 1292 | It used to disable the minor mode, major mode, and text-property keymaps, | ||
| 1293 | whereas now it simply has higher precedence. | ||
| 1294 | |||
| 1295 | ** `kill-region' has lost its `yank-handler' optional argument. | ||
| 1296 | |||
| 1297 | ** `(input-pending-p)' no longer runs other timers that are ready to run. | ||
| 1298 | The new optional CHECK-TIMERS parameter allows for the prior behavior. | ||
| 1299 | |||
| 1300 | ** `defvar' and `defcustom' in a let-binding affect the "external" default. | ||
| 1301 | |||
| 1302 | ** The syntax of ?» and ?« is now punctuation instead of matched parens. | ||
| 1303 | Some languages match those as »...«, and others as «...», so it is | ||
| 1304 | better for Emacs to stay neutral by default. | ||
| 1305 | |||
| 1306 | ** `read-event' does not always decode chars in ttys any more. As was the case | ||
| 1307 | in Emacs 22 and before, `read-event' (and `read-char') by default read raw | ||
| 1308 | bytes from the terminal. If you want to read decoded chars instead (as was | ||
| 1309 | always the case in Emacs-23, for example), pass a non-nil | ||
| 1310 | `inherit-input-method' argument. | ||
| 1311 | |||
| 1312 | ** In `symbol-function', nil and "unbound" are indistinguishable. | ||
| 1313 | `symbol-function' does not signal a `void-function' error any more. | ||
| 1314 | To determine if a symbol's function definition is void, use `fboundp'. | ||
| 1315 | |||
| 1316 | ** `defadvice' does not honor the `freeze' flag and cannot advise | ||
| 1317 | special-forms any more. | ||
| 1318 | |||
| 1319 | ** `dolist' no longer binds VAR while evaluating the RESULT form, | ||
| 1320 | when lexical binding is enabled. Previously, VAR was bound to nil, | ||
| 1321 | which often led to spurious unused-variable warnings. | ||
| 1322 | |||
| 1323 | ** The return value of `backup-buffer' has changed. | ||
| 1324 | The second argument is no longer an SELinux context, instead it is an | ||
| 1325 | alist of extended attributes as returned by the new function | ||
| 1326 | `file-extended-attributes'. The attributes can be applied to another | ||
| 1327 | file using `set-file-extended-attributes'. | ||
| 1328 | |||
| 1329 | ** By default `copy-file' no longer copies file permission bits to an | ||
| 1330 | existing destination; and it sets the file permission bits of a newly | ||
| 1331 | created destination to those of the source, masked by the default file | ||
| 1332 | permissions. To copy the file permission bits, pass t as the | ||
| 1333 | PRESERVE-PERMISSIONS argument of `copy-file'. | ||
| 1334 | |||
| 1335 | ** `visited-file-modtime' now returns -1 for nonexistent files. | ||
| 1336 | Formerly it returned a list (-1 LOW USEC PSEC), but this was ambiguous | ||
| 1337 | in the presence of files with negative time stamps. | ||
| 1338 | |||
| 1339 | ** Frame-local variables that affect redisplay do not work any more. | ||
| 1340 | More specifically, redisplay does not bother to check for a frame-local | ||
| 1341 | value when looking up variables. | ||
| 1342 | |||
| 1343 | ** In compiled Lisp files, the header no longer includes a timestamp. | ||
| 1344 | |||
| 1345 | ** The option `inhibit-local-menu-bar-menus' has been removed. | ||
| 1346 | |||
| 1347 | |||
| 1348 | * Lisp Changes in Emacs 24.4 | ||
| 1349 | |||
| 1350 | ** Change to the Emacs Lisp coding conventions: the package descriptor | ||
| 1351 | and name of global variables, constants, and functions should be separated | ||
| 1352 | by two hyphens if the symbol is not meant to be used by other packages. | ||
| 1353 | |||
| 1354 | ** The second argument of `eval' can now specify a lexical environment. | ||
| 1355 | |||
| 1356 | ** New macro `define-alternatives' can be used to define generic commands. | ||
| 1357 | Generic commands are interactive functions whose implementation can be | ||
| 1358 | selected among several alternatives, as a matter of user preference. | ||
| 1359 | |||
| 1360 | ** Numeric comparison functions =, <, >, <=, >= can now take many arguments. | ||
| 1361 | |||
| 1362 | ** New functions `special-form-p' and `macrop'. | ||
| 1363 | |||
| 1364 | ** New macro `with-eval-after-load'. | ||
| 1365 | This is like the old `eval-after-load', but better behaved. | ||
| 1366 | |||
| 1367 | ** If you give a symbol a `defalias-fset-function' property, `defalias' | ||
| 1368 | on that symbol will use the associated value as a function to call | ||
| 1369 | in place of `fset'. | ||
| 1370 | |||
| 1371 | ** New variable `enable-dir-local-variables'. | ||
| 1372 | Directory-local variables are ignored if this is nil. This may be | ||
| 1373 | useful for modes that want to ignore directory-locals while still | ||
| 1374 | respecting file-local variables. | ||
| 1375 | |||
| 1376 | ** `read-regexp' now uses the new variable `read-regexp-defaults-function' | ||
| 1377 | as a function to call to provide default values. | ||
| 1378 | |||
| 1379 | ** New functions `group-gid' and `group-real-gid'. | ||
| 1380 | |||
| 1381 | ** New function `get-pos-property'. | ||
| 1382 | |||
| 1383 | ** New hook `pre-redisplay-function'. | ||
| 1384 | |||
| 1385 | ** `byte-compile-interactive-only-functions' is now obsolete. | ||
| 1386 | To specify that a command should only be called interactively, give it | ||
| 1387 | a non-nil `interactive-only' property. | ||
| 1388 | |||
| 1389 | ** New function `string-suffix-p'. | ||
| 1390 | |||
| 1391 | ** `split-string' now takes an optional argument TRIM. | ||
| 1392 | The value, if non-nil, is a regexp that specifies what to trim from | ||
| 1393 | the start and end of each substring. | ||
| 1394 | |||
| 1395 | ** Completion | ||
| 1396 | |||
| 1397 | *** The separator used by `completing-read-multiple' is now a regexp. | ||
| 1398 | The default `crm-separator' has been changed to allow surrounding spaces | ||
| 1399 | around the comma. | ||
| 1400 | |||
| 1401 | *** New function `completion-table-with-cache' is a wrapper for | ||
| 1402 | `completion-table-dynamic' that caches the result of the last lookup. | ||
| 1403 | |||
| 1404 | *** New function `completion-table-merge' to combine several | ||
| 1405 | completion tables by merging their completions. | ||
| 1406 | |||
| 1407 | *** The `common-substring' argument of `display-completion-list', | ||
| 1408 | which has been documented as obsolete since Emacs 23.1, is now _really_ | ||
| 1409 | obsolete, and no longer advertised. Instead either call | ||
| 1410 | `completion-hilit-commonality' to add the highlighting; or use | ||
| 1411 | `completion-all-completions', which returns highlighted strings. | ||
| 1412 | |||
| 1413 | ** Encoding and decoding of text | ||
| 1414 | |||
| 1415 | *** New coding-system `prefer-utf-8'. | ||
| 1416 | This is like `undecided' but prefers UTF-8 on decoding if the text to | ||
| 1417 | be decoded does not contain any invalid UTF-8 sequences. On encoding, | ||
| 1418 | any non-ASCII characters are automatically encoded as UTF-8. | ||
| 1419 | |||
| 1420 | *** New attributes of coding-systems whose type is `undecided'. | ||
| 1421 | Two new attributes, `:inhibit-null-byte-detection' and | ||
| 1422 | `:inhibit-iso-escape-detection', determine how to detect encoding of | ||
| 1423 | text that includes null bytes and ISO-2022 escape sequences, respectively. | ||
| 1424 | Each of these attributes can be either nil, zero, or t. If t, decoding | ||
| 1425 | text ignores null bytes and ISO-2022 sequences, respectively. If nil, | ||
| 1426 | null bytes cause text to be decoded with no-conversion, and ISO-2022 | ||
| 1427 | sequences cause Emacs to assume the text is encoded in one of the ISO-2022 | ||
| 1428 | encodings, such as iso-2022-7bit. If zero, Emacs consults the variables | ||
| 1429 | `inhibit-null-byte-detection' and `inhibit-iso-escape-detection'. | ||
| 1430 | The new attribute `:prefer-utf-8', if non-nil, causes Emacs to prefer | ||
| 1431 | UTF-8 encoding and decoding, whenever possible. | ||
| 1432 | |||
| 1433 | These attributes are only meaningful for coding-systems of type `undecided'. | ||
| 1434 | (The type of a coding-system is determined by its `:coding-type' attribute | ||
| 1435 | and can be accessed by calling the `coding-system-type' function.) | ||
| 1436 | |||
| 1437 | ** Error-handling | ||
| 1438 | |||
| 1439 | *** New function `define-error'. | ||
| 1440 | |||
| 1441 | *** `with-demoted-errors' takes an additional argument `format'. | ||
| 1442 | |||
| 1443 | *** Errors from timer functions are no longer silently discarded, | ||
| 1444 | but are reported as messages. So you may see "Error running timer" | ||
| 1445 | messages from code that was failing silently till now. Set | ||
| 1446 | `debug-on-error' non-nil to get a real error and a backtrace. | ||
| 1447 | |||
| 1448 | ** Faces | ||
| 1449 | |||
| 1450 | *** Face specs set via Custom themes now replace the `defface' spec | ||
| 1451 | rather than inheriting from it. In other words, setting a face via a | ||
| 1452 | theme now behaves like setting it via Customize: you only need to | ||
| 1453 | specify the attributes that you want, you don't need to unset those | ||
| 1454 | that you don't want. | ||
| 1455 | |||
| 1456 | *** The function `face-spec-set' is now like `setq' for face specs. | ||
| 1457 | Its third arg now accepts values specifying a face spec type (defface, | ||
| 1458 | custom, or override spec), and the relevant spec is set accordingly. | ||
| 1459 | |||
| 1460 | *** New face spec attribute :distant-foreground | ||
| 1461 | specifies foreground to use if background color is near the foreground | ||
| 1462 | color that would otherwise have been used. | ||
| 1463 | |||
| 1464 | *** New function `add-face-text-property', which can be used to | ||
| 1465 | conveniently prepend/append new face properties. | ||
| 1466 | |||
| 1467 | *** New face characteristic (supports :underline (:style wave)) | ||
| 1468 | specifies whether or not the terminal can display a wavy line. | ||
| 1469 | |||
| 1470 | ** File-handling | ||
| 1471 | |||
| 1472 | *** Support for filesystem notifications. | ||
| 1473 | Emacs now supports notifications of filesystem changes, such as | ||
| 1474 | creation, modification, and deletion of files. This requires the | ||
| 1475 | `glib' API, or the 'inotify' API (on GNU/Linux systems only). On | ||
| 1476 | MS-Windows systems, this is supported for Windows XP and newer. | ||
| 1477 | |||
| 1478 | *** The 9th element returned by `file-attributes' is now unspecified. | ||
| 1479 | Formerly, it was t if the file's gid would change if file were deleted | ||
| 1480 | and recreated. This value has been inaccurate for years on many | ||
| 1481 | platforms, and nobody seems to have noticed or cared. | ||
| 1482 | |||
| 1483 | *** The 6th argument to `copy-file' has been renamed to | ||
| 1484 | PRESERVE-PERMISSIONS as it now handles ACL entries and the traditional | ||
| 1485 | Unix file permission bits as well as SELinux context. | ||
| 1486 | |||
| 1487 | *** The function `file-ownership-preserved-p' now has an optional | ||
| 1488 | argument GROUP which causes it check for file group too. This can be | ||
| 1489 | used in place of the 9th element of `file-attributes'. | ||
| 1490 | |||
| 1491 | *** The function `set-visited-file-modtime' now accepts a 0 or -1 argument, | ||
| 1492 | with the same interpretation as the returned value of `visited-file-modtime'. | ||
| 1493 | |||
| 1494 | ** Image API | ||
| 1495 | |||
| 1496 | *** `image-animated-p' is now `image-multi-frame-p'. | ||
| 1497 | It returns non-nil for any image that contains multiple frames, | ||
| 1498 | whether or not it specifies a frame delay. | ||
| 1499 | |||
| 1500 | *** New variable `image-default-frame-delay' gives the frame delay for | ||
| 1501 | animated images which do not specify a frame delay. | ||
| 1502 | |||
| 1503 | *** New functions `image-current-frame' and `image-show-frame' for getting | ||
| 1504 | and setting the current frame of a multi-frame image. | ||
| 1505 | |||
| 1506 | ** ImageMagick | ||
| 1507 | |||
| 1508 | *** ImageMagick images now support the :max-width and :max-height keywords. | ||
| 1509 | |||
| 1510 | *** When using `create-image' with image data, you can pass a :format | ||
| 1511 | attribute (via the property-list argument) in order to help | ||
| 1512 | ImageMagick detect the image type. The value should be a MIME | ||
| 1513 | content-type that is found in the new variable `image-format-suffixes'. | ||
| 1514 | |||
| 1515 | ** Revert and Autorevert | ||
| 1516 | |||
| 1517 | *** If Emacs is compiled with file notification support, it uses notifications | ||
| 1518 | instead of checking file time stamps. To disable this, set the user option | ||
| 1519 | `auto-revert-use-notify' to nil. Alternatively, you can specify a regular | ||
| 1520 | expression matching directories to be excluded from file notifications via | ||
| 1521 | `auto-revert-notify-exclude-dir-regexp'. | ||
| 1522 | |||
| 1523 | *** The default values of `buffer-stale-function', `revert-buffer-function', | ||
| 1524 | and `revert-buffer-insert-file-contents-function' are no longer nil. | ||
| 1525 | Instead they default to functions that do what the nil value used to. | ||
| 1526 | |||
| 1527 | *** `buffer-stale-function' is now used for buffers visiting files too. | ||
| 1528 | |||
| 1529 | *** The new user option `auto-revert-remote-files' enables reversion | ||
| 1530 | of remote files, if non-nil. | ||
| 1531 | |||
| 1532 | ** Terminal | ||
| 1533 | |||
| 1534 | *** Functions to pop up menus and dialogs now work on all terminals, | ||
| 1535 | including TTYs. This includes `x-popup-menu', `x-popup-dialog', | ||
| 1536 | `message-box', `yes-or-no-p', etc. | ||
| 1537 | |||
| 1538 | The function `display-popup-menus-p' will now return non-nil for a | ||
| 1539 | display or frame whenever a mouse is supported on that display or frame. | ||
| 1540 | |||
| 1541 | *** New hook `tty-setup-hook', run at the end of initializing a text terminal. | ||
| 1542 | |||
| 1543 | *** The hook `term-setup-hook' is obsolete. It is entirely equivalent | ||
| 1544 | to `emacs-startup-hook'. See also the new `tty-setup-hook'. | ||
| 1545 | |||
| 1546 | ** Minor internal changes to the details of lock files. | ||
| 1547 | The lock for DIR/FILE is now _always_ DIR/.#FILE. | ||
| 1548 | If DIR/.#FILE already exists and is not an Emacs lock file, | ||
| 1549 | Emacs makes no attempt to lock DIR/FILE. (Previously, it fell back to | ||
| 1550 | numbered lock files DIR/.#FILE.0...). | ||
| 1551 | On file systems that do not support symbolic links, the lock is now a | ||
| 1552 | regular file with contents being what would have been in the symlink. | ||
| 1553 | |||
| 1554 | ** New bool-vector set operation functions: | ||
| 1555 | *** `bool-vector-exclusive-or' | ||
| 1556 | *** `bool-vector-union' | ||
| 1557 | *** `bool-vector-intersection' | ||
| 1558 | *** `bool-vector-set-difference' | ||
| 1559 | *** `bool-vector-not' | ||
| 1560 | *** `bool-vector-subsetp' | ||
| 1561 | *** `bool-vector-count-consecutive' | ||
| 1562 | *** `bool-vector-count-population' | ||
| 1563 | |||
| 1564 | ** New library subr-x.el with miscellaneous small utility functions: | ||
| 1565 | *** `hash-table-keys' | ||
| 1566 | *** `hash-table-values' | ||
| 1567 | *** `string-blank-p' | ||
| 1568 | *** `string-empty-p' | ||
| 1569 | *** `string-join' | ||
| 1570 | *** `string-reverse' | ||
| 1571 | *** `string-trim-left' | ||
| 1572 | *** `string-trim-right' | ||
| 1573 | *** `string-trim' | ||
| 1574 | *** `string-remove-prefix' | ||
| 1575 | *** `string-remove-suffix' | ||
| 1576 | |||
| 1577 | ** The `time-to-seconds' alias to `float-time' is no longer marked obsolete. | ||
| 1578 | |||
| 1579 | ** The spelling of the rx.el category `chinese-two-byte' has been | ||
| 1580 | corrected (the first 'e' was missing). | ||
| 1581 | |||
| 1582 | ** EIEIO namespace cleanup, obsolete-aliasing functions to use `eieio-' prefix: | ||
| 1583 | *** object-name -> eieio-object-name | ||
| 1584 | *** object-class -> eieio-object-class | ||
| 1585 | *** object-class-fast -> eieio--object-class | ||
| 1586 | *** object-class-name -> eieio-object-class-name | ||
| 1587 | *** object-name-string -> eieio-object-name-string | ||
| 1588 | *** object-num-slots -> eieio--object-num-slots | ||
| 1589 | *** object-set-name-string -> eieio-object-set-name-string | ||
| 1590 | *** class-of -> eieio-object-class | ||
| 1591 | *** class-name -> eieio-class-name | ||
| 1592 | *** class-parent -> eieio-class-parent | ||
| 1593 | *** class-parents -> eieio-class-parents | ||
| 1594 | *** class-parents-fast -> eieio-class-parents-fast | ||
| 1595 | *** class-children -> eieio-class-children | ||
| 1596 | *** class-num-slots -> eieio--class-num-slots | ||
| 1597 | *** class-precedence-list -> eieio-class-precedence-list | ||
| 1598 | *** class-direct-subclasses -> eieio-class-children | ||
| 1599 | *** class-direct-superclasses -> eieio-class-parents | ||
| 1600 | |||
| 1601 | ** Obsoleted functions | ||
| 1602 | *** `log10' | ||
| 1603 | *** `dont-compile' | ||
| 1604 | *** `lisp-complete-symbol' | ||
| 1605 | *** `field-complete' | ||
| 1606 | *** `minibuffer-completion-contents' | ||
| 1607 | *** `isearch-nonincremental-exit-minibuffer' | ||
| 1608 | *** `isearch-filter-visible' | ||
| 1609 | *** `generic-make-keywords-list' | ||
| 1610 | *** `get-upcase-table' (use `case-table-get-table' instead). | ||
| 1611 | |||
| 1612 | ** `with-wrapper-hook' is obsoleted by `add-function'. | ||
| 1613 | The few hooks that used with-wrapper-hook are replaced as follows: | ||
| 1614 | *** `abbrev-expand-function' obsoletes `abbrev-expand-functions'. | ||
| 1615 | *** `completion-in-region-function' obsoletes `completion-in-region-functions'. | ||
| 1616 | *** `filter-buffer-substring-function' obsoletes `filter-buffer-substring-functions'. | ||
| 1617 | |||
| 1618 | |||
| 1619 | * Changes in Emacs 24.4 on Non-Free Operating Systems | ||
| 1620 | |||
| 1621 | ** New Core Text based font backend for Mac OS X 10.5 and newer. | ||
| 1622 | To use the old font backend, use the following on the command line: | ||
| 1623 | % defaults write org.gnu.Emacs FontBackend ns | ||
| 1624 | GNUstep and Mac OS X 10.4 use the old font backend. | ||
| 1625 | |||
| 1626 | ** Improved fullscreen support on Mac OS X 10.7 and newer, where the | ||
| 1627 | default fullscreen method is now "native" fullscreen. To use the | ||
| 1628 | old style fullscreen, customize `ns-use-native-fullscreen' to nil. | ||
| 1629 | |||
| 1630 | ** On Mac OS X 10.7 and newer, Emacs can use sRGB colorspace, and does so | ||
| 1631 | by default. Customize `ns-use-srgb-colorspace' to go back to the old method. | ||
| 1632 | Note that this does not apply to images. | ||
| 1633 | |||
| 1634 | ** The procedure for building Emacs on MS-Windows has changed. | ||
| 1635 | It is now built by running the same configure script as on all other | ||
| 1636 | platforms. This requires the MSYS environment and MinGW development | ||
| 1637 | tools. See the updated instructions in nt/INSTALL for details. | ||
| 1638 | |||
| 1639 | Using the Posix configure script and Makefiles also means a change in | ||
| 1640 | the directory structure of the Emacs installation on Windows. It is | ||
| 1641 | now the same as on GNU and Unix systems. In particular, the auxiliary | ||
| 1642 | programs, such as cmdproxy.exe and hexl.exe, are in | ||
| 1643 | libexec/emacs/VERSION/i686-pc-mingw32 (where VERSION is the Emacs | ||
| 1644 | version), version-independent site-lisp is in share/emacs/site-lisp, | ||
| 1645 | version-specific Lisp files are in share/emacs/VERSION/lisp and in | ||
| 1646 | share/emacs/VERSION/site-lisp, Info docs are in share/info, and data | ||
| 1647 | files are in share/emacs/VERSION/etc. (Emacs knows about all these | ||
| 1648 | directories and will find the files in there automatically; there's no | ||
| 1649 | need to set any variables due to this change.) | ||
| 1650 | |||
| 1651 | ** Emacs on Windows 2000 and later can now access files and directories | ||
| 1652 | whose names cannot be encoded in the current system codepage. | ||
| 1653 | |||
| 1654 | The new variable `w32-unicode-filenames' controls this feature: if it | ||
| 1655 | is t, Emacs uses Unicode APIs to pass file names to system calls, | ||
| 1656 | which lifts the limitation of file names to the current locale. | ||
| 1657 | |||
| 1658 | ** Lock files now work on MS-Windows. | ||
| 1659 | This helps to prevent losing your edits if the same file is being | ||
| 1660 | edited in another Emacs session or by another user. See the node | ||
| 1661 | "Interlocking" in the Emacs User Manual for the details. To disable | ||
| 1662 | file locking, customize `create-lockfiles' to nil. | ||
| 1663 | |||
| 1664 | ** The "generate a backtrace on fatal error" feature now works on MS-Windows. | ||
| 1665 | The backtrace is written to the 'emacs_backtrace.txt' file in the | ||
| 1666 | directory where Emacs was running. | ||
| 1667 | |||
| 1668 | ** The `network-interface-list' and `network-interface-info' functions | ||
| 1669 | are now available on MS-Windows. | ||
| 1670 | |||
| 1671 | ** The variable `buffer-file-type' is no longer supported. | ||
| 1672 | Setting it has no effect, and %t in the mode-line format is ignored. | ||
| 1673 | Likewise, `file-name-buffer-file-type-alist' is now obsolete, and | ||
| 1674 | modifying it has no effect. | ||
| 1675 | |||
| 1676 | |||
| 1677 | * Installation Changes in Emacs 24.3 | ||
| 1678 | |||
| 1679 | ** The default X toolkit is now Gtk+ version 3. | ||
| 1680 | If you don't pass `--with-x-toolkit' to configure, or if you use | ||
| 1681 | `--with-x-toolkit=gtk' or `--with-x-toolkit=yes', configure will try | ||
| 1682 | to build with Gtk+ version 3, and if that fails, try Gtk+ version 2. | ||
| 1683 | You can explicitly require a specific version by passing | ||
| 1684 | `--with-x-toolkit=gtk2' or `--with-x-toolkit=gtk3' to configure. | ||
| 1685 | |||
| 1686 | ** New configure option `--enable-link-time-optimization', to utilize | ||
| 1687 | an appropriate feature provided by GCC since version 4.5.0. | ||
| 1688 | |||
| 1689 | ** New configure option `--without-all' to disable most of the optional | ||
| 1690 | features (image support, etc.) that are normally enabled by default. | ||
| 1691 | |||
| 1692 | ** New configure option `--enable-gcc-warnings' (for developing/debugging | ||
| 1693 | Emacs). If building with GCC, this enables compile-time checks that | ||
| 1694 | warn/give errors about possibly-questionable C code. On a recent GNU | ||
| 1695 | system there should be no warnings; on older and on non-GNU systems | ||
| 1696 | the results may be useful to developers. | ||
| 1697 | |||
| 1698 | ** The configure option `--enable-use-lisp-union-type' has been | ||
| 1699 | renamed to `--enable-check-lisp-object-type', as the resulting | ||
| 1700 | Lisp_Object type no longer uses a union to implement the compile time | ||
| 1701 | check that this option enables. | ||
| 1702 | |||
| 1703 | ** The configure option `--disable-maintainer-mode' has been removed, | ||
| 1704 | as it was confusingly-named and rarely useful. | ||
| 1705 | |||
| 1706 | ** The configure options `--program-prefix', `--program-suffix', and | ||
| 1707 | `--program-transform-name' apply to more than just the installed | ||
| 1708 | binaries. Now they also affect the man pages, icons, and the | ||
| 1709 | etc/emacs.desktop file; but not the info pages, since this would break | ||
| 1710 | links between the various manuals. | ||
| 1711 | |||
| 1712 | ** You can use `NO_BIN_LINK=t make install' to prevent the installation | ||
| 1713 | overwriting "emacs" in the installation bin/ directory with a link | ||
| 1714 | to "emacs-VERSION". | ||
| 1715 | |||
| 1716 | ** Emacs uses libtinfo in preference to libncurses, if available. | ||
| 1717 | |||
| 1718 | ** On FreeBSD and NetBSD, configure no longer adds /usr/local/lib and | ||
| 1719 | /usr/pkg/lib to the linker search path. You must add them yourself if | ||
| 1720 | you want them. | ||
| 1721 | |||
| 1722 | ** The standalone scripts `rcs-checkin' and `vcdiff' have been removed | ||
| 1723 | (from the bin and libexec directories, respectively). The former is | ||
| 1724 | no longer relevant, the latter is replaced by lisp (in vc-sccs.el). | ||
| 1725 | |||
| 1726 | |||
| 1727 | * Startup Changes in Emacs 24.3 | ||
| 1728 | |||
| 1729 | ** Emacs no longer searches for `leim-list.el' files beneath the standard | ||
| 1730 | lisp/ directory. There should not be any there anyway. If you have | ||
| 1731 | been adding them there, put them somewhere else; e.g., site-lisp. | ||
| 1732 | |||
| 1733 | ** The `--no-site-lisp' command line option now works for Nextstep builds. | ||
| 1734 | |||
| 1735 | |||
| 1736 | * Changes in Emacs 24.3 | ||
| 1737 | |||
| 1738 | ** Help | ||
| 1739 | |||
| 1740 | *** `C-h f' (`describe-function') can now perform autoloading. | ||
| 1741 | When this command is called for an autoloaded function whose docstring | ||
| 1742 | contains a key substitution construct, that function's library is | ||
| 1743 | automatically loaded, so that the documentation can be shown | ||
| 1744 | correctly. To disable this, set `help-enable-auto-load' to nil. | ||
| 1745 | |||
| 1746 | *** `C-h f' now reports previously-autoloaded functions as "autoloaded", | ||
| 1747 | even after their associated libraries have been loaded (and the | ||
| 1748 | autoloads have been redefined as functions). | ||
| 1749 | |||
| 1750 | ** ImageMagick | ||
| 1751 | |||
| 1752 | *** Images displayed via ImageMagick now support transparency and the | ||
| 1753 | :background image specification property. | ||
| 1754 | |||
| 1755 | *** When available, ImageMagick support is automatically enabled. | ||
| 1756 | It is no longer necessary to call `imagemagick-register-types' | ||
| 1757 | explicitly to install ImageMagick image types; that function is called | ||
| 1758 | automatically at startup, or when customizing an imagemagick- option. | ||
| 1759 | |||
| 1760 | *** Setting `imagemagick-types-inhibit' to t now disables the use of | ||
| 1761 | ImageMagick to view images. (You must call `imagemagick-register-types' | ||
| 1762 | afterwards if you do not use customize to change this.) | ||
| 1763 | |||
| 1764 | *** The new variable `imagemagick-enabled-types' also affects which | ||
| 1765 | ImageMagick types are treated as images. The function | ||
| 1766 | `imagemagick-filter-types' returns the list of types that will be | ||
| 1767 | treated as images. | ||
| 1768 | |||
| 1769 | ** Minibuffer | ||
| 1770 | |||
| 1771 | *** In minibuffer filename prompts, `C-M-f' and `C-M-b' now move to the | ||
| 1772 | next and previous path separator, respectively. | ||
| 1773 | |||
| 1774 | *** `minibuffer-electric-default-mode' can shorten "(default ...)" to "[...]" | ||
| 1775 | in minibuffer prompts. Just set `minibuffer-eldef-shorten-default' | ||
| 1776 | non-nil before enabling the mode. | ||
| 1777 | |||
| 1778 | ** Mode line | ||
| 1779 | |||
| 1780 | *** New option `mode-line-default-help-echo' specifies the help text | ||
| 1781 | (shown in a tooltip or in the echo area) for any part of the mode line | ||
| 1782 | that does not have its own specialized help text. | ||
| 1783 | |||
| 1784 | *** You can now click mouse-3 in the coding system indicator to invoke | ||
| 1785 | `set-buffer-file-coding-system'. | ||
| 1786 | |||
| 1787 | ** Server and client | ||
| 1788 | |||
| 1789 | *** emacsclient now obeys string values for `initial-buffer-choice', | ||
| 1790 | if it is told to open a new frame without specifying any file to visit | ||
| 1791 | or expression to evaluate. | ||
| 1792 | |||
| 1793 | *** New option `server-auth-key' specifies a shared server key. | ||
| 1794 | |||
| 1795 | ** Emacs now generates backtraces on fatal errors. | ||
| 1796 | On encountering a fatal error, Emacs now outputs a textual description | ||
| 1797 | of the fatal signal, and a short backtrace on platforms like glibc | ||
| 1798 | that support backtraces. | ||
| 1799 | |||
| 1800 | ** `C-x C-q' is now bound to the new minor mode `read-only-mode'. | ||
| 1801 | This minor mode replaces `toggle-read-only', which is now obsolete. | ||
| 1802 | |||
| 1803 | ** Most `y-or-n' prompts now allow you to scroll the selected window. | ||
| 1804 | Typing `C-v' or `M-v' at a y-or-n prompt scrolls forward or backward | ||
| 1805 | respectively, without exiting from the prompt. | ||
| 1806 | |||
| 1807 | ** In the Package Menu, newly-available packages are listed as "new", | ||
| 1808 | and sorted above the other "available" packages by default. | ||
| 1809 | |||
| 1810 | ** If your Emacs was built from a repository checkout, the new variable | ||
| 1811 | `emacs-bzr-version' contains information about the bzr revision used. | ||
| 1812 | |||
| 1813 | ** New option `create-lockfiles' specifies usage of lockfiles. | ||
| 1814 | It defaults to t. Changing it to nil inhibits the creation of lock | ||
| 1815 | files (use this with caution). | ||
| 1816 | |||
| 1817 | ** New option `enable-remote-dir-locals', if non-nil, allows directory-local | ||
| 1818 | variables on remote hosts. | ||
| 1819 | |||
| 1820 | ** The entry for PCL-CVS has been removed from the Tools menu. | ||
| 1821 | The PCL-CVS commands are still available via the keyboard. | ||
| 1822 | |||
| 1823 | ** Using "unibyte: t" in Lisp source files is obsolete. | ||
| 1824 | Use "coding: raw-text" instead. | ||
| 1825 | |||
| 1826 | ** In the buffer made by `M-x report-emacs-bug', the `C-c m' binding | ||
| 1827 | has been changed to `C-c M-i' (`report-emacs-bug-insert-to-mailer'). | ||
| 1828 | The previous binding, introduced in Emacs 24.1, was a mistake, because | ||
| 1829 | `C-c LETTER' bindings are reserved for user customizations. | ||
| 1830 | |||
| 1831 | ** Internationalization | ||
| 1832 | |||
| 1833 | *** New language environment: Persian. | ||
| 1834 | |||
| 1835 | *** New input method `vietnamese-vni'. | ||
| 1836 | |||
| 1837 | ** Nextstep (GNUstep / Mac OS X) port | ||
| 1838 | |||
| 1839 | *** Support for fullscreen and the frame parameter fullscreen. | ||
| 1840 | |||
| 1841 | *** A file dialog is used for open/save operations initiated from the | ||
| 1842 | menu/toolbar. | ||
| 1843 | |||
| 1844 | |||
| 1845 | * Editing Changes in Emacs 24.3 | ||
| 1846 | |||
| 1847 | ** Search and Replace | ||
| 1848 | |||
| 1849 | *** Non-regexp Isearch now performs "lax" space matching. | ||
| 1850 | Each sequence of spaces in the supplied search string may match any | ||
| 1851 | sequence of one or more whitespace characters, as specified by the | ||
| 1852 | variable `search-whitespace-regexp'. (This variable is also used by a | ||
| 1853 | similar existing feature for regexp Isearch.) | ||
| 1854 | |||
| 1855 | *** New Isearch command `M-s SPC' toggles lax space matching. | ||
| 1856 | This applies to both ordinary and regexp Isearch. | ||
| 1857 | |||
| 1858 | *** New option `replace-lax-whitespace'. | ||
| 1859 | If non-nil, `query-replace' uses flexible whitespace matching too. | ||
| 1860 | The default is nil. | ||
| 1861 | |||
| 1862 | *** Global `M-s _' starts a symbol (identifier) incremental search, | ||
| 1863 | and `M-s _' in Isearch toggles symbol search mode. | ||
| 1864 | `M-s c' in Isearch toggles search case-sensitivity. | ||
| 1865 | |||
| 1866 | ** Navigation commands | ||
| 1867 | |||
| 1868 | *** New binding `M-g c' for `goto-char'. | ||
| 1869 | |||
| 1870 | *** New binding `M-g TAB' for `move-to-column'. | ||
| 1871 | |||
| 1872 | *** `M-g TAB' (`move-to-column') prompts for a column number if called | ||
| 1873 | interactively with no prefix arg. Previously, it moved to column 1. | ||
| 1874 | |||
| 1875 | ** New option `yank-handled-properties' allows processing of text | ||
| 1876 | properties on yanked text, in ways that are more general than just | ||
| 1877 | removing them (as is done by `yank-excluded-properties'). | ||
| 1878 | |||
| 1879 | ** New option `delete-trailing-lines' specifies whether | ||
| 1880 | M-x delete-trailing-whitespace should delete trailing lines at the end | ||
| 1881 | of the buffer. It defaults to t. | ||
| 1882 | |||
| 1883 | ** `C-u M-=' now counts lines/words/characters in the entire buffer. | ||
| 1884 | |||
| 1885 | ** `C-x 8 RET' is now bound to `insert-char', which is now a command. | ||
| 1886 | `ucs-insert' is now an obsolete alias for `insert-char'. | ||
| 1887 | |||
| 1888 | ** The `z' key no longer has a binding in most special modes. | ||
| 1889 | It used to be bound to `kill-this-buffer', but `z' is too easy to | ||
| 1890 | accidentally type. | ||
| 1891 | |||
| 1892 | ** New command `C-x r M-w' (`copy-rectangle-as-kill'). | ||
| 1893 | It copies the region-rectangle as the last rectangle kill. | ||
| 1894 | |||
| 1895 | ** Registers | ||
| 1896 | |||
| 1897 | *** `C-x r +' is now overloaded to invoke `append-to-register'. | ||
| 1898 | |||
| 1899 | *** New option `register-separator' specifies the register containing | ||
| 1900 | the text to put between collected texts for use with | ||
| 1901 | M-x append-to-register and M-x prepend-to-register. | ||
| 1902 | |||
| 1903 | |||
| 1904 | * Changes in Specialized Modes and Packages in Emacs 24.3 | ||
| 1905 | |||
| 1906 | ** Common Lisp emulation (CL) | ||
| 1907 | |||
| 1908 | *** CL's main entry is now (require 'cl-lib). | ||
| 1909 | `cl-lib' is like the old `cl' except that it uses the namespace cleanly; | ||
| 1910 | i.e., all its definitions have the "cl-" prefix (and internal definitions | ||
| 1911 | use the "cl--" prefix). | ||
| 1912 | |||
| 1913 | If `cl' provided a feature under the name `foo', then `cl-lib' | ||
| 1914 | provides it under the name `cl-foo' instead; with the exceptions of the | ||
| 1915 | few `cl' definitions that had to use `foo*' to avoid conflicts with | ||
| 1916 | pre-existing Elisp entities. These have been renamed to `cl-foo' | ||
| 1917 | rather than `cl-foo*'. | ||
| 1918 | |||
| 1919 | The old `cl' is now deprecated and is mainly just a bunch of aliases that | ||
| 1920 | provide the old, non-prefixed names. Some exceptions are listed below: | ||
| 1921 | |||
| 1922 | *** `cl-flet' is not like `flet' (which is deprecated). | ||
| 1923 | Instead it obeys the behavior of Common-Lisp's `flet'. | ||
| 1924 | In particular, in cl-flet function definitions are lexically scoped, | ||
| 1925 | whereas in flet the scoping is dynamic. | ||
| 1926 | |||
| 1927 | *** `cl-labels' is slightly different from `labels'. | ||
| 1928 | The difference is that it relies on the `lexical-binding' machinery | ||
| 1929 | (as opposed to the `lexical-let' machinery used previously) to capture | ||
| 1930 | definitions in closures, so such closures will only work if `lexical-binding' | ||
| 1931 | is in use. | ||
| 1932 | |||
| 1933 | *** `cl-letf' is not exactly like `letf'. | ||
| 1934 | The only difference is in details that relate to some deprecated usage | ||
| 1935 | of `symbol-function' in place forms. | ||
| 1936 | |||
| 1937 | *** `progv' was rewritten to use the `let' machinery. | ||
| 1938 | A side effect is that variables without corresponding values are bound | ||
| 1939 | to nil rather than being made unbound. | ||
| 1940 | |||
| 1941 | *** The following methods of extending `setf' are obsolete | ||
| 1942 | (use features from gv.el instead): | ||
| 1943 | `define-modify-macro' (use `gv-letplace') | ||
| 1944 | `defsetf' (use `gv-define-simple-setter' or `gv-define-setter') | ||
| 1945 | `define-setf-expander' (use `gv-define-setter' or `gv-define-expander') | ||
| 1946 | `get-setf-method' no longer exists (see "Incompatible Lisp Changes") | ||
| 1947 | |||
| 1948 | ** Diff mode | ||
| 1949 | |||
| 1950 | *** Changes are now highlighted using the same color scheme as in | ||
| 1951 | modern VCSes. Deletions are displayed in red (new faces | ||
| 1952 | `diff-refine-removed' and `smerge-refined-removed', and new definition | ||
| 1953 | of `diff-removed'), insertions in green (new faces `diff-refine-added' | ||
| 1954 | and `smerge-refined-added', and new definition of `diff-added'). | ||
| 1955 | |||
| 1956 | *** The variable `diff-use-changed-face' defines whether to use the | ||
| 1957 | face `diff-changed', or `diff-removed' and `diff-added' to highlight | ||
| 1958 | changes in context diffs. | ||
| 1959 | |||
| 1960 | *** The new command `diff-delete-trailing-whitespace' removes trailing | ||
| 1961 | whitespace introduced by a diff. | ||
| 1962 | |||
| 1963 | ** Ediff now uses the same color scheme as Diff mode. | ||
| 1964 | |||
| 1965 | ** Python mode | ||
| 1966 | |||
| 1967 | A new version of python.el, which provides several new features, including: | ||
| 1968 | per-buffer shells, better indentation, Python 3 support, and improved | ||
| 1969 | shell-interaction compatible with iPython (and virtually any other | ||
| 1970 | text based shell). | ||
| 1971 | |||
| 1972 | *** Some user options have been replaced/renamed, including (old -> new): | ||
| 1973 | **** python-indent -> python-indent-offset | ||
| 1974 | **** python-guess-indent -> python-indent-guess-indent-offset | ||
| 1975 | **** python-pdbtrack-do-tracking-p -> python-pdbtrack-activate | ||
| 1976 | **** python-use-skeletons -> python-skeleton-autoinsert | ||
| 1977 | |||
| 1978 | *** Some user options have been removed, including: | ||
| 1979 | |||
| 1980 | **** `python-indent-string-contents': Strings are never indented. | ||
| 1981 | |||
| 1982 | **** `python-honour-comment-indentation': | ||
| 1983 | Comments are always considered as indentation markers. | ||
| 1984 | |||
| 1985 | **** `python-continuation-offset': Indentation is automatically | ||
| 1986 | calculated in a pep8 compliant way depending on the context. | ||
| 1987 | |||
| 1988 | **** `python-shell-prompt-alist', `python-shell-continuation-prompt-alist': | ||
| 1989 | Have no direct mapping as the shell interaction is completely different. | ||
| 1990 | |||
| 1991 | **** `python-python-command', `python-jython-command': | ||
| 1992 | Replaced by `python-shell-interpreter'. | ||
| 1993 | |||
| 1994 | **** `inferior-python-filter-regexp', `python-remove-cwd-from-path', | ||
| 1995 | `python-pdbtrack-minor-mode-string', `python-source-modes': | ||
| 1996 | No longer relevant. | ||
| 1997 | |||
| 1998 | *** Some commands have been replaced (old -> new): | ||
| 1999 | **** python-insert-class -> python-skeleton-class | ||
| 2000 | **** python-insert-def -> python-skeleton-def | ||
| 2001 | **** python-insert-for -> python-skeleton-for | ||
| 2002 | **** python-insert-if -> python-skeleton-if | ||
| 2003 | **** python-insert-try/except -> python-skeleton-try | ||
| 2004 | **** python-insert-try/finally -> python-skeleton-try | ||
| 2005 | **** python-insert-while -> python-skeleton-while | ||
| 2006 | **** python-find-function -> python-nav-jump-to-defun | ||
| 2007 | **** python-next-statement -> python-nav-forward-sentence | ||
| 2008 | **** python-previous-statement -> python-nav-backward-sentence | ||
| 2009 | **** python-beginning-of-defun-function -> python-nav-beginning-of-defun | ||
| 2010 | **** python-end-of-defun-function -> python-nav-end-of-defun | ||
| 2011 | **** python-send-buffer -> python-shell-send-buffer | ||
| 2012 | **** python-send-defun -> python-shell-send-defun | ||
| 2013 | **** python-send-region -> python-shell-send-region | ||
| 2014 | **** python-send-region-and-go -> emulate with python-shell-send-region | ||
| 2015 | and python-shell-switch-to-shell | ||
| 2016 | **** python-send-string -> python-shell-send-string | ||
| 2017 | **** python-switch-to-python -> python-shell-switch-to-shell | ||
| 2018 | **** python-describe-symbol -> python-eldoc-at-point | ||
| 2019 | |||
| 2020 | ** D-Bus | ||
| 2021 | |||
| 2022 | *** New variables `dbus-compiled-version' and `dbus-runtime-version'. | ||
| 2023 | |||
| 2024 | *** The D-Bus object manager interface is implemented. | ||
| 2025 | |||
| 2026 | *** Variables of type :(u)int32 and :(u)int64 accept floating points, | ||
| 2027 | if their value does not fit into Emacs's integer range. | ||
| 2028 | |||
| 2029 | *** The function `dbus-call-method' is now non-blocking. | ||
| 2030 | It can be interrupted by `C-g'. `dbus-call-method-non-blocking' is obsolete. | ||
| 2031 | |||
| 2032 | *** Signals can also be sent as unicast messages. | ||
| 2033 | |||
| 2034 | *** The argument list of `dbus-register-signal' has been extended, | ||
| 2035 | according to the new match rule types of D-Bus. | ||
| 2036 | |||
| 2037 | *** `dbus-init-bus' supports private connections. | ||
| 2038 | |||
| 2039 | *** There is a new function `dbus-setenv'. | ||
| 2040 | |||
| 2041 | ** `desktop-path' no longer includes the "." directory. | ||
| 2042 | Desktop files are now located in ~/.emacs.d by default. | ||
| 2043 | |||
| 2044 | ** Dired | ||
| 2045 | |||
| 2046 | *** `dired-do-async-shell-command' executes each file sequentially | ||
| 2047 | if the command ends in `;' (when operating on multiple files). | ||
| 2048 | Otherwise, it executes the command on each file in parallel. | ||
| 2049 | |||
| 2050 | *** Typing `M-n' in the minibuffer of `dired-do-chmod', `dired-do-chgrp', | ||
| 2051 | `dired-do-chown', and `dired-do-touch' yanks the attributes of the | ||
| 2052 | file at point. | ||
| 2053 | |||
| 2054 | *** When the region is active, `m' (`dired-mark'), `u' (`dired-unmark'), | ||
| 2055 | `DEL' (`dired-unmark-backward'), and `d' (`dired-flag-file-deletion') | ||
| 2056 | mark/unmark/flag all files in the active region. | ||
| 2057 | |||
| 2058 | *** The minibuffer default for `=' (`dired-diff') has changed. | ||
| 2059 | It is now the backup file for the file at point, if one exists. | ||
| 2060 | In Transient Mark mode the default is the file at the active mark. | ||
| 2061 | |||
| 2062 | *** `M-=' is no longer bound to `dired-backup-diff' in Dired buffers. | ||
| 2063 | The global binding for `M-=', `count-words-region' is in effect. | ||
| 2064 | |||
| 2065 | ** ERC | ||
| 2066 | |||
| 2067 | *** New module "notifications", which can send a notification when you | ||
| 2068 | receive a private message or your nickname is mentioned. | ||
| 2069 | |||
| 2070 | *** ERC will look up server/channel names via auth-source and use any | ||
| 2071 | channel keys found. | ||
| 2072 | |||
| 2073 | *** New option `erc-lurker-hide-list', similar to `erc-hide-list', but | ||
| 2074 | only applies to messages sent by lurkers. | ||
| 2075 | |||
| 2076 | ** reStructuredText mode | ||
| 2077 | |||
| 2078 | *** Keybindings (see `C-c C-h'), TAB indentation, filling and auto-filling, | ||
| 2079 | fontification, comment handling, and customization have all been revised | ||
| 2080 | and improved. | ||
| 2081 | |||
| 2082 | *** Support for `imenu' and `which-function-mode'. | ||
| 2083 | |||
| 2084 | *** The reStructuredText syntax is more closely covered. | ||
| 2085 | Sphinx support has been improved. | ||
| 2086 | |||
| 2087 | *** `rst-insert-list' inserts new list or continues existing lists. | ||
| 2088 | |||
| 2089 | *** A negative prefix argument always works for `rst-adjust'. | ||
| 2090 | |||
| 2091 | *** The window configuration is reset after displaying a TOC. | ||
| 2092 | |||
| 2093 | *** The constant `rst-version' describes the rst.el package version. | ||
| 2094 | |||
| 2095 | ** Ruby mode | ||
| 2096 | |||
| 2097 | *** Support for percent literals and recognition of regular expressions | ||
| 2098 | in method calls without parentheses with more methods, including Cucumber | ||
| 2099 | steps definitions. | ||
| 2100 | |||
| 2101 | *** Improved syntax highlighting and indentation. | ||
| 2102 | |||
| 2103 | *** New command `ruby-toggle-block', bound to `C-c {'. | ||
| 2104 | |||
| 2105 | *** Some non-standard keybindings/commands have been removed: | ||
| 2106 | |||
| 2107 | **** `ruby-electric-brace'; use `electric-indent-mode' instead. | ||
| 2108 | |||
| 2109 | **** `ruby-mark-defun'; use `mark-defun'. | ||
| 2110 | |||
| 2111 | **** `ruby-beginning-of-defun' and `ruby-end-of-defun' are replaced by | ||
| 2112 | appropriate settings for the variables `beginning-of-defun-function' | ||
| 2113 | and `end-of-defun-function'. | ||
| 2114 | |||
| 2115 | **** Non-standard keybindings for `backward-kill-word', `comment-region', | ||
| 2116 | `reindent-then-newline-and-indent' and `newline' have been removed. | ||
| 2117 | |||
| 2118 | ** Shell Script mode | ||
| 2119 | |||
| 2120 | *** Pairing of parens/quotes uses `electric-pair-mode' instead of skeleton-pair. | ||
| 2121 | |||
| 2122 | *** `sh-electric-here-document-mode' now controls auto-insertion of here-docs. | ||
| 2123 | |||
| 2124 | *** `sh-use-smie' lets you choose a new indentation and navigation code. | ||
| 2125 | |||
| 2126 | ** VHDL mode | ||
| 2127 | |||
| 2128 | *** The free software compiler GHDL is supported (and now the default). | ||
| 2129 | |||
| 2130 | *** Support for the VHDL-AMS packages has been added/updated. | ||
| 2131 | |||
| 2132 | *** Updated to the 2002 revision of the VHDL standard. | ||
| 2133 | |||
| 2134 | *** Accepts \r and \f as whitespace. | ||
| 2135 | |||
| 2136 | ** Apropos | ||
| 2137 | |||
| 2138 | *** The faces used by Apropos are now directly customizable. | ||
| 2139 | These faces are named `apropos-symbol', `apropos-keybinding', and so on; | ||
| 2140 | see the `apropos' Custom group for details. | ||
| 2141 | |||
| 2142 | *** The old options whose values specified faces to use have been removed | ||
| 2143 | (i.e. `apropos-symbol-face', `apropos-keybinding-face', `apropos-label-face', | ||
| 2144 | `apropos-match-face' and `apropos-property-face'.). | ||
| 2145 | |||
| 2146 | ** Buffer Menu | ||
| 2147 | |||
| 2148 | *** This package has been rewritten to use Tabulated List mode. | ||
| 2149 | |||
| 2150 | *** Option `Buffer-menu-buffer+size-width' is now obsolete. | ||
| 2151 | Use `Buffer-menu-name-width' and `Buffer-menu-size-width' instead. | ||
| 2152 | |||
| 2153 | ** Calc | ||
| 2154 | |||
| 2155 | *** Algebraic simplification mode is now the default. | ||
| 2156 | To restrict to the limited simplifications given by the former | ||
| 2157 | default simplification mode, use `m I'. | ||
| 2158 | |||
| 2159 | ** Calendar | ||
| 2160 | |||
| 2161 | *** You can customize the header text that appears above each calendar month. | ||
| 2162 | See the variable `calendar-month-header'. | ||
| 2163 | |||
| 2164 | *** New LaTeX calendar style, produced by `cal-tex-cursor-week2-summary'. | ||
| 2165 | |||
| 2166 | *** The calendars produced by cal-html include holidays. | ||
| 2167 | Customize `cal-html-holidays' to change this. | ||
| 2168 | |||
| 2169 | ** CEDET | ||
| 2170 | |||
| 2171 | *** The major modes from the parser generators "Bovine" and "Wisent" | ||
| 2172 | are now properly integrated in Emacs. The file suffixes ".by" and ".wy" | ||
| 2173 | are in `auto-mode-alist', and the corresponding manuals are included. | ||
| 2174 | |||
| 2175 | *** EDE | ||
| 2176 | |||
| 2177 | **** Menu support for the "Configuration" feature. This allows users to | ||
| 2178 | choose the active configuration (such as debug or install) from the menu. | ||
| 2179 | |||
| 2180 | **** New command `ede-set' to interactively set project-local variables. | ||
| 2181 | |||
| 2182 | **** Support for compiling, debugging, and running in "generic" projects. | ||
| 2183 | |||
| 2184 | **** Autoconf editing support for M4 macros with complex arguments. | ||
| 2185 | |||
| 2186 | **** Compilation support for the "linux" project type. | ||
| 2187 | |||
| 2188 | **** "simple" projects have been removed; use "generic" projects instead. | ||
| 2189 | |||
| 2190 | *** Semantic | ||
| 2191 | |||
| 2192 | **** Support for parsing #include statements inside a namespace in C/C++. | ||
| 2193 | |||
| 2194 | **** Improved support for 'extern "C"' declarations in C/C++. | ||
| 2195 | |||
| 2196 | **** The ability to ignore more common special C/C++ preprocessor symbols, | ||
| 2197 | such as '__nonnull' and '__asm'. Add '__cplusplus' macro when parsing C++. | ||
| 2198 | If available, include cdefs.h as an additional source of preprocessor symbols. | ||
| 2199 | |||
| 2200 | **** Improved C/C++ function pointer parsing. | ||
| 2201 | |||
| 2202 | **** In Python, support for converting imports to include file names. | ||
| 2203 | |||
| 2204 | **** Ability to dynamically determine the Python load path. | ||
| 2205 | |||
| 2206 | **** Support for the Python 'WITH' and 'AT' keywords. | ||
| 2207 | |||
| 2208 | **** Improved tooltip completion. | ||
| 2209 | |||
| 2210 | *** SRecode | ||
| 2211 | |||
| 2212 | **** The SRecode manual is now included. | ||
| 2213 | |||
| 2214 | **** Tag generation supports constructor/destructor settings and system | ||
| 2215 | include differentiation. | ||
| 2216 | |||
| 2217 | **** Addition of 'Framework' support: Frameworks are specified when a | ||
| 2218 | particular kind of library (such as Android) is needed in a common language | ||
| 2219 | mode (like Java). | ||
| 2220 | |||
| 2221 | **** Support for nested templates and let variables override based on priority. | ||
| 2222 | |||
| 2223 | **** Support for merging tables from multiple related modes, such as | ||
| 2224 | default -> c++ -> arduino. | ||
| 2225 | |||
| 2226 | ** Compile has a new option `compilation-always-kill'. | ||
| 2227 | |||
| 2228 | ** Customize | ||
| 2229 | |||
| 2230 | *** `custom-reset-button-menu' now defaults to t. | ||
| 2231 | |||
| 2232 | *** Non-option variables are never matched in `customize-apropos' and | ||
| 2233 | `customize-apropos-options' (i.e., the prefix argument does nothing for | ||
| 2234 | these commands now). | ||
| 2235 | |||
| 2236 | ** Term | ||
| 2237 | |||
| 2238 | *** The variables `term-default-fg-color' and `term-default-bg-color' | ||
| 2239 | are now deprecated in favor of the customizable face `term'. | ||
| 2240 | |||
| 2241 | *** You can customize how to display ANSI terminal colors and styles | ||
| 2242 | by customizing the corresponding `term-color-<COLOR>', | ||
| 2243 | `term-color-underline' and `term-color-bold' faces. | ||
| 2244 | |||
| 2245 | ** Tramp | ||
| 2246 | |||
| 2247 | *** The syntax has been extended in order to allow ad-hoc proxy definitions. | ||
| 2248 | |||
| 2249 | *** Remote processes are now also supported on remote MS-Windows hosts. | ||
| 2250 | |||
| 2251 | ** URL | ||
| 2252 | |||
| 2253 | *** Structs made by `url-generic-parse-url' have nil `attributes' slot. | ||
| 2254 | Previously, this slot stored semicolon-separated attribute-value pairs | ||
| 2255 | appended to some imap URLs, but this is not compatible with RFC 3986. | ||
| 2256 | So now the `filename' slot stores the entire path and query components, | ||
| 2257 | and the `attributes' slot is always nil. | ||
| 2258 | |||
| 2259 | *** New function `url-encode-url' for encoding a URI string. | ||
| 2260 | The `url-retrieve' function now uses this to encode its URL argument, | ||
| 2261 | in case that is not properly encoded. | ||
| 2262 | |||
| 2263 | ** notifications.el supports now version 1.2 of the Notifications API. | ||
| 2264 | The function `notifications-get-capabilities' returns the supported | ||
| 2265 | server properties. | ||
| 2266 | |||
| 2267 | ** Flymake uses fringe bitmaps to indicate errors and warnings. | ||
| 2268 | See `flymake-fringe-indicator-position', `flymake-error-bitmap' and | ||
| 2269 | `flymake-warning-bitmap'. | ||
| 2270 | |||
| 2271 | ** The FFAP option `ffap-url-unwrap-remote' can now be a list of strings, | ||
| 2272 | specifying URL types that should be converted to remote file names at | ||
| 2273 | the FFAP prompt. The default is now '("ftp"). | ||
| 2274 | |||
| 2275 | ** New Ibuffer `derived-mode' filter, bound to `/ M'. | ||
| 2276 | The old binding for `/ M' (filter by used-mode) is now bound to `/ m'. | ||
| 2277 | |||
| 2278 | ** New option `mouse-avoidance-banish-position' specifies where the | ||
| 2279 | `banish' mouse avoidance setting moves the mouse. | ||
| 2280 | |||
| 2281 | ** In Perl mode, new option `perl-indent-parens-as-block' causes non-block | ||
| 2282 | closing brackets to be aligned with the line of the opening bracket. | ||
| 2283 | |||
| 2284 | ** In Proced mode, new command `proced-renice' renices marked processes. | ||
| 2285 | |||
| 2286 | ** New option `async-shell-command-buffer' specifies the buffer to use | ||
| 2287 | for a new asynchronous `shell-command' when the default output buffer | ||
| 2288 | `*Async Shell Command*' is already in use. | ||
| 2289 | |||
| 2290 | ** SQL mode has a new option `sql-db2-escape-newlines'. | ||
| 2291 | If non-nil, newlines sent to the command interpreter will be escaped | ||
| 2292 | by a backslash. The default does not escape the newlines and assumes | ||
| 2293 | that the sql statement will be terminated by a semicolon. | ||
| 2294 | |||
| 2295 | ** New command `tabulated-list-sort', bound to `S' in Tabulated List mode | ||
| 2296 | (and modes that derive from it), sorts the column at point, or the Nth | ||
| 2297 | column if a numeric prefix argument is given. | ||
| 2298 | |||
| 2299 | ** `which-func-modes' now defaults to t, so Which Function mode, when | ||
| 2300 | enabled, applies to all applicable major modes. | ||
| 2301 | |||
| 2302 | ** `winner-mode-hook' now runs when the mode is disabled, as well as when | ||
| 2303 | it is enabled. | ||
| 2304 | |||
| 2305 | ** Follow mode no longer works by using advice. | ||
| 2306 | The option `follow-intercept-processes' has been removed. | ||
| 2307 | |||
| 2308 | ** `javascript-generic-mode' is now an obsolete alias for `js-mode'. | ||
| 2309 | |||
| 2310 | ** Hooks renamed to avoid obsolete "-hooks" suffix: | ||
| 2311 | *** semantic-lex-reset-hooks -> semantic-lex-reset-functions | ||
| 2312 | *** semantic-change-hooks -> semantic-change-functions | ||
| 2313 | *** semantic-edits-new-change-hooks -> semantic-edits-new-change-functions | ||
| 2314 | *** semantic-edits-delete-change-hooks -> semantic-edits-delete-change-functions | ||
| 2315 | *** semantic-edits-reparse-change-hooks -> semantic-edits-reparse-change-functions | ||
| 2316 | *** semanticdb-save-database-hooks -> semanticdb-save-database-functions | ||
| 2317 | *** c-prepare-bug-report-hooks -> c-prepare-bug-report-hook | ||
| 2318 | *** rcirc-sentinel-hooks -> rcirc-sentinel-functions | ||
| 2319 | *** rcirc-receive-message-hooks -> rcirc-receive-message-functions | ||
| 2320 | *** rcirc-activity-hooks -> rcirc-activity-functions | ||
| 2321 | *** rcirc-print-hooks -> rcirc-print-functions | ||
| 2322 | *** dbus-event-error-hooks -> dbus-event-error-functions | ||
| 2323 | *** eieio-pre-method-execution-hooks -> eieio-pre-method-execution-functions | ||
| 2324 | *** checkdoc-style-hooks -> checkdoc-style-functions | ||
| 2325 | *** checkdoc-comment-style-hooks -> checkdoc-comment-style-functions | ||
| 2326 | *** archive-extract-hooks -> archive-extract-hook | ||
| 2327 | *** filesets-cache-fill-content-hooks -> filesets-cache-fill-content-hook | ||
| 2328 | *** hfy-post-html-hooks -> hfy-post-html-hook | ||
| 2329 | *** nndiary-request-create-group-hooks -> nndiary-request-create-group-functions | ||
| 2330 | *** nndiary-request-update-info-hooks -> nndiary-request-update-info-functions | ||
| 2331 | *** nndiary-request-accept-article-hooks -> nndiary-request-accept-article-functions | ||
| 2332 | *** gnus-subscribe-newsgroup-hooks -> gnus-subscribe-newsgroup-functions | ||
| 2333 | |||
| 2334 | ** Obsolete packages | ||
| 2335 | |||
| 2336 | *** assoc.el | ||
| 2337 | In most cases, assoc+member+push+delq work just as well. | ||
| 2338 | And in any case it's just a terrible package: ugly semantics, terrible | ||
| 2339 | inefficiency, and not namespace-clean. | ||
| 2340 | *** bruce.el | ||
| 2341 | *** cust-print.el | ||
| 2342 | *** ledit.el | ||
| 2343 | *** mailpost.el | ||
| 2344 | *** mouse-sel.el | ||
| 2345 | *** patcomp.el | ||
| 2346 | |||
| 2347 | |||
| 2348 | * Incompatible Lisp Changes in Emacs 24.3 | ||
| 2349 | |||
| 2350 | ** Docstrings starting with `*' no longer indicate user options. | ||
| 2351 | Only variables defined using `defcustom' are considered user options. | ||
| 2352 | The function `user-variable-p' is now an obsolete alias for | ||
| 2353 | `custom-variable-p'. | ||
| 2354 | |||
| 2355 | ** The return values of `defalias', `defun' and `defmacro' have changed, | ||
| 2356 | and are now undefined. For backwards compatibility, `defun' and | ||
| 2357 | `defmacro' currently return the name of the newly defined | ||
| 2358 | function/macro, but this should not be relied upon. | ||
| 2359 | |||
| 2360 | ** `random' by default now returns a different random sequence in | ||
| 2361 | every Emacs run. Use `(random S)', where S is a string, to set the | ||
| 2362 | random seed to a value based on S, in order to get a repeatable | ||
| 2363 | sequence in later calls. | ||
| 2364 | |||
| 2365 | ** If the NEWTEXT arg to `replace-match' contains a substring "\?", | ||
| 2366 | that substring is inserted literally even if the LITERAL arg is | ||
| 2367 | non-nil, instead of causing an error to be signaled. | ||
| 2368 | |||
| 2369 | ** `select-window' now always makes the window's buffer current. | ||
| 2370 | It does so even if the window was selected before. | ||
| 2371 | |||
| 2372 | ** The function `x-select-font' can return a font spec, instead of a | ||
| 2373 | font name as a string. Whether it returns a font spec or a font name | ||
| 2374 | depends on the graphical library. | ||
| 2375 | |||
| 2376 | ** `face-spec-set' no longer sets frame-specific attributes when the | ||
| 2377 | third argument is a frame (that usage was obsolete since Emacs 22.2). | ||
| 2378 | |||
| 2379 | ** `set-buffer-multibyte' now signals an error in narrowed buffers. | ||
| 2380 | |||
| 2381 | ** The CL package's `get-setf-method' function no longer exists. | ||
| 2382 | Generalized variables are now part of core Emacs Lisp, and implemented | ||
| 2383 | differently to the way cl.el used to do it. It is not possible to | ||
| 2384 | define a compatible replacement for `get-setf-method'. See the file | ||
| 2385 | gv.el for internal details of the new implementation. | ||
| 2386 | |||
| 2387 | ** The arguments of `dbus-register-signal' are no longer just strings, | ||
| 2388 | but keywords or keyword-string pairs. The old argument list will | ||
| 2389 | still be supported for Emacs 24.x. | ||
| 2390 | |||
| 2391 | ** Miscellaneous name changes | ||
| 2392 | Some Lisp symbols have been renamed to correct their spelling, | ||
| 2393 | or to be more consistent with standard Emacs terminology. | ||
| 2394 | |||
| 2395 | *** Renamed functions | ||
| 2396 | **** hangul-input-method-inactivate -> hangul-input-method-deactivate | ||
| 2397 | **** inactivate-input-method -> deactivate-input-method | ||
| 2398 | **** quail-inactivate -> quail-deactivate | ||
| 2399 | **** robin-inactivate -> robin-deactivate | ||
| 2400 | **** viper-inactivate-input-method -> viper-deactivate-input-method | ||
| 2401 | **** viper-inactivate-input-method-action -> | ||
| 2402 | viper-deactivate-input-method-action | ||
| 2403 | **** ucs-input-inactivate -> ucs-input-deactivate | ||
| 2404 | |||
| 2405 | *** Renamed hooks | ||
| 2406 | The old hooks are still supported for backward compatibility, but they | ||
| 2407 | are deprecated and will be removed eventually. | ||
| 2408 | **** input-method-inactivate-hook -> input-method-deactivate-hook | ||
| 2409 | **** robin-inactivate-hook -> robin-deactivate-hook | ||
| 2410 | **** quail-inactivate-hook -> quail-deactivate-hook | ||
| 2411 | |||
| 2412 | *** Renamed variables | ||
| 2413 | **** follow-deactive-menu -> follow-inactive-menu | ||
| 2414 | **** inactivate-current-input-method-function -> | ||
| 2415 | deactivate-current-input-method-function | ||
| 2416 | |||
| 2417 | ** Some obsolete functions, variables, and faces have been removed: | ||
| 2418 | *** `last-input-char', `last-command-char', `unread-command-char' | ||
| 2419 | *** `facemenu-unlisted-faces' | ||
| 2420 | *** `rmail-decode-mime-charset' | ||
| 2421 | *** `iswitchb-read-buffer' | ||
| 2422 | *** `sc-version', `sc-submit-bug-report' | ||
| 2423 | *** `set-char-table-default' | ||
| 2424 | *** `string-to-sequence' (use `string-to-list' or `string-to-vector') | ||
| 2425 | *** `compile-internal' | ||
| 2426 | *** `modeline' | ||
| 2427 | *** `mode-line-inverse-video' | ||
| 2428 | *** `follow-mode-off-hook' | ||
| 2429 | *** `cvs-commit-buffer-require-final-newline' | ||
| 2430 | (use `log-edit-require-final-newline' instead) | ||
| 2431 | *** `cvs-changelog-full-paragraphs' | ||
| 2432 | (use `log-edit-changelog-full-paragraphs' instead) | ||
| 2433 | *** `cvs-diff-ignore-marks', `cvs-diff-buffer-name' | ||
| 2434 | *** `vc-ignore-vc-files' (use `vc-handled-backends' instead) | ||
| 2435 | *** `vc-master-templates' (use `vc-handled-backends' instead) | ||
| 2436 | *** `vc-checkout-carefully' | ||
| 2437 | |||
| 2438 | |||
| 2439 | * Lisp Changes in Emacs 24.3 | ||
| 2440 | |||
| 2441 | ** CL-style generalized variables are now in core Elisp. | ||
| 2442 | `setf' is autoloaded; `push' and `pop' accept generalized variables. | ||
| 2443 | You can define your own generalized variables using `gv-define-simple-setter', | ||
| 2444 | `gv-define-setter', etc. | ||
| 2445 | |||
| 2446 | ** Emacs tries to macroexpand interpreted (non-compiled) files during load. | ||
| 2447 | This can significantly speed up execution of non-byte-compiled code, | ||
| 2448 | but can also bump into previously unnoticed cyclic dependencies. | ||
| 2449 | These are generally harmless: they will simply cause the macro calls | ||
| 2450 | to be left for later expansion (as before), but will result in a | ||
| 2451 | warning ("Eager macro-expansion skipped due to cycle") describing the cycle. | ||
| 2452 | You may wish to restructure your code so this does not happen. | ||
| 2453 | |||
| 2454 | ** New sampling-based Elisp profiler. | ||
| 2455 | Try M-x profiler-start, do some work, and then call M-x profiler-report. | ||
| 2456 | When finished, use M-x profiler-stop. The sampling rate can be based on | ||
| 2457 | CPU time or memory allocations. | ||
| 2458 | |||
| 2459 | ** `defun' also accepts a (declare DECLS) form, like `defmacro'. | ||
| 2460 | The interpretation of the DECLS is determined by `defun-declarations-alist'. | ||
| 2461 | |||
| 2462 | ** New macros `setq-local' and `defvar-local'. | ||
| 2463 | |||
| 2464 | ** Face underlining can now use a wave. | ||
| 2465 | |||
| 2466 | ** `read-regexp' has a new argument HISTORY; the first argument PROMPT | ||
| 2467 | of `read-regexp' accepts a string ending with a colon and space, and its | ||
| 2468 | second argument DEFAULTS can be a list of strings accessible via `M-n' | ||
| 2469 | in the minibuffer ahead of other hard-coded useful regexp-related values. | ||
| 2470 | More commands use `read-regexp' now to read their regexp arguments. | ||
| 2471 | |||
| 2472 | ** Completion | ||
| 2473 | |||
| 2474 | *** New function `completion-table-with-quoting' to handle completion | ||
| 2475 | in the presence of quoting, such as file completion in shell buffers. | ||
| 2476 | |||
| 2477 | *** New function `completion-table-subvert' to use an existing completion | ||
| 2478 | table, but with a different prefix. | ||
| 2479 | |||
| 2480 | ** Debugger | ||
| 2481 | |||
| 2482 | *** New error type and new function `user-error'. | ||
| 2483 | These do not trigger the debugger. | ||
| 2484 | |||
| 2485 | *** New option `debugger-bury-or-kill', saying what to do with the | ||
| 2486 | debugger buffer when exiting debug. | ||
| 2487 | |||
| 2488 | *** Set `debug-on-message' to enter the debugger when a certain | ||
| 2489 | message is displayed in the echo area. This can be useful when trying | ||
| 2490 | to work out which code is doing something. | ||
| 2491 | |||
| 2492 | *** New var `inhibit-debugger', automatically set to prevent accidental | ||
| 2493 | recursive invocations. | ||
| 2494 | |||
| 2495 | ** Window handling | ||
| 2496 | |||
| 2497 | *** New command `fit-frame-to-buffer' adjusts the frame height to | ||
| 2498 | fit the contents. | ||
| 2499 | |||
| 2500 | *** The command `fit-window-to-buffer' can adjust the frame height | ||
| 2501 | if the new option `fit-frame-to-buffer' is non-nil. | ||
| 2502 | |||
| 2503 | *** New macro `with-temp-buffer-window', similar to | ||
| 2504 | `with-output-to-temp-buffer'. | ||
| 2505 | |||
| 2506 | *** `temp-buffer-resize-mode' no longer resizes windows that have been | ||
| 2507 | reused. | ||
| 2508 | |||
| 2509 | *** New option `switch-to-buffer-preserve-window-point' to restore a | ||
| 2510 | window's point when switching buffers. | ||
| 2511 | |||
| 2512 | *** New display action alist entries `window-height' and `window-width' | ||
| 2513 | specify the size of new windows created by `display-buffer'. | ||
| 2514 | |||
| 2515 | *** New display action alist entry `pop-up-frame-parameters', if | ||
| 2516 | non-nil, specifies frame parameters to give any newly-created frame. | ||
| 2517 | |||
| 2518 | *** New display action alist entry `inhibit-switch-frame', if non-nil, | ||
| 2519 | tells display action functions to avoid changing which frame is | ||
| 2520 | selected. | ||
| 2521 | |||
| 2522 | *** New display action alist entry `previous-window', if non-nil, | ||
| 2523 | specifies window to reuse in `display-buffer-in-previous-window'. | ||
| 2524 | |||
| 2525 | *** New display action functions `display-buffer-below-selected', | ||
| 2526 | and `display-buffer-in-previous-window'. | ||
| 2527 | |||
| 2528 | *** The functions `get-lru-window', `get-mru-window' and `get-largest-window' | ||
| 2529 | now accept a third argument to avoid choosing the selected window. | ||
| 2530 | |||
| 2531 | *** Additional values recognized for option `window-combination-limit'. | ||
| 2532 | |||
| 2533 | *** The following variables are obsolete, as they can be replaced by | ||
| 2534 | appropriate entries in the `display-buffer-alist' function introduced | ||
| 2535 | in Emacs 24.1: | ||
| 2536 | **** `dired-shrink-to-fit' | ||
| 2537 | **** `display-buffer-reuse-frames' | ||
| 2538 | **** `display-buffer-function' | ||
| 2539 | **** `special-display-buffer-names' | ||
| 2540 | **** `special-display-frame-alist' | ||
| 2541 | **** `special-display-function' | ||
| 2542 | **** `special-display-regexps' | ||
| 2543 | |||
| 2544 | ** Time | ||
| 2545 | |||
| 2546 | *** `current-time-string' no longer requires that its argument's year | ||
| 2547 | must be in the range 1000..9999. It now works with any year supported | ||
| 2548 | by the underlying C implementation. | ||
| 2549 | |||
| 2550 | *** `current-time' now returns extended-format time stamps | ||
| 2551 | (HIGH LOW USEC PSEC), where the new PSEC slot specifies picoseconds. | ||
| 2552 | PSEC is typically a multiple of 1000 on current machines. Other | ||
| 2553 | functions that use this format, such as `file-attributes' and | ||
| 2554 | `format-time-string', have been changed accordingly. Old-format time | ||
| 2555 | stamps are still accepted. | ||
| 2556 | |||
| 2557 | *** The format of timers in `timer-list' and `timer-idle-list' is now | ||
| 2558 | [TRIGGERED-P HI-SECS LO-SECS USECS REPEAT-DELAY FUNCTION ARGS IDLE-DELAY PSECS]. | ||
| 2559 | The PSECS slot is new, and uses picosecond resolution. It can be | ||
| 2560 | accessed via the new `timer--psecs' accessor. | ||
| 2561 | |||
| 2562 | *** Last-modified time stamps in undo lists now are of the form | ||
| 2563 | (t HI-SECS LO-SECS USECS PSECS) instead of (t HI-SECS . LO-SECS). | ||
| 2564 | |||
| 2565 | ** EIEIO | ||
| 2566 | |||
| 2567 | *** Improved security when handling persistent objects: | ||
| 2568 | |||
| 2569 | **** `eieio-persistent-read' now features optional arguments for specifying | ||
| 2570 | the class to load, as well as a flag stating whether subclasses are allowed; | ||
| 2571 | if provided, other classes will be rejected by the reader. For | ||
| 2572 | compatibility with existing code, if the class is omitted only a | ||
| 2573 | warning is issued. | ||
| 2574 | |||
| 2575 | **** New specialized reader for pulling in classes and signaling errors | ||
| 2576 | without evaluation of suspicious code. | ||
| 2577 | |||
| 2578 | **** All slots that contain objects must have a :type. Slots with lists | ||
| 2579 | of objects must use a new type predicate for a list of an object type. | ||
| 2580 | |||
| 2581 | *** Support for `find-function' and similar utilities, through the addition | ||
| 2582 | of filename support to generated symbols. | ||
| 2583 | |||
| 2584 | ** Floating point functions now always return special values like NaN, | ||
| 2585 | instead of signaling errors, if given invalid args; e.g., (log -1.0). | ||
| 2586 | Previously, they returned NaNs on some platforms but signaled errors | ||
| 2587 | on others. The affected functions are acos, asin, tan, exp, expt, | ||
| 2588 | log, log10, sqrt, and mod. | ||
| 2589 | |||
| 2590 | ** New fringe bitmap `exclamation-mark'. | ||
| 2591 | |||
| 2592 | ** Miscellaneous changes to special forms and macros | ||
| 2593 | |||
| 2594 | *** `defun' and `defmacro' are now macros rather than special forms. | ||
| 2595 | |||
| 2596 | *** `kbd' is now a function rather than a macro. | ||
| 2597 | |||
| 2598 | ** Miscellaneous new functions | ||
| 2599 | |||
| 2600 | *** `set-temporary-overlay-map' sets up a temporary keymap that | ||
| 2601 | takes precedence over most other maps for a short while (normally one key). | ||
| 2602 | |||
| 2603 | *** `autoloadp' tests if its argument is an autoloaded object. | ||
| 2604 | |||
| 2605 | *** `autoload-do-load' performs the autoloading operation. | ||
| 2606 | |||
| 2607 | *** `buffer-narrowed-p' tests if the buffer is narrowed. | ||
| 2608 | |||
| 2609 | *** `file-name-base' returns a file name sans directory and extension. | ||
| 2610 | |||
| 2611 | *** `function-get' fetches a function property, following aliases. | ||
| 2612 | |||
| 2613 | *** `posnp' tests if an object is a `posn'. | ||
| 2614 | |||
| 2615 | *** `system-users' returns the user names on the system. | ||
| 2616 | |||
| 2617 | *** `system-groups' returns the group names on the system. | ||
| 2618 | |||
| 2619 | *** `tty-top-frame' returns the topmost frame of a text terminal. | ||
| 2620 | |||
| 2621 | ** The following functions and variables are obsolete: | ||
| 2622 | *** `automount-dir-prefix' (use `directory-abbrev-alist') | ||
| 2623 | *** `buffer-has-markers-at' | ||
| 2624 | *** `macro-declaration-function' (use `macro-declarations-alist') | ||
| 2625 | *** `window-system-version' (provides no useful information) | ||
| 2626 | *** `dired-pop-to-buffer' (use `dired-mark-pop-up') | ||
| 2627 | *** `query-replace-interactive' | ||
| 2628 | *** `font-list-limit' (has had no effect since Emacs < 23) | ||
| 2629 | |||
| 2630 | |||
| 2631 | * Changes in Emacs 24.3 on Non-Free Operating Systems | ||
| 2632 | |||
| 2633 | ** Cygwin builds can use the native MS Windows user interface. | ||
| 2634 | Pass `--with-w32' to configure. The default remains the X11 interface. | ||
| 2635 | |||
| 2636 | ** Two new functions are available in Cygwin builds: | ||
| 2637 | `cygwin-convert-file-name-from-windows' and | ||
| 2638 | `cygwin-convert-file-name-to-windows'. These functions allow Lisp | ||
| 2639 | code to access the Cygwin file-name mapping machinery to convert | ||
| 2640 | between Cygwin and Windows-native file and directory names. | ||
| 2641 | |||
| 2642 | ** When invoked with the -nw switch to run on the Windows text-mode terminal, | ||
| 2643 | Emacs now supports `mouse-highlight', help-echo (in the echo area), and | ||
| 2644 | `mouse-autoselect-window'. | ||
| 2645 | |||
| 2646 | ** On MS Windows Vista and later Emacs now supports symbolic links. | ||
| 2647 | |||
| 2648 | ** On MS Windows, you can pass `--without-libxml2' to configure.bat to omit | ||
| 2649 | support for libxml2, even if its presence is detected. | ||
| 2650 | |||
| 2651 | ** On Mac OS X, the Nextstep port requires OS X 10.4 or later. | ||
| 2652 | |||
| 2653 | ** On Mac OS X, configure no longer automatically adds the Fink "/sw" | ||
| 2654 | directories to the search path. You must add them yourself if you want them. | ||
| 2655 | |||
| 2656 | |||
| 2657 | * Changes in Emacs 24.2 | ||
| 2658 | |||
| 2659 | ** This is mainly a bug-fix release. | ||
| 2660 | |||
| 2661 | |||
| 2662 | * Installation Changes in Emacs 24.1 | ||
| 2663 | |||
| 2664 | ** Emacs can be compiled with Gtk+ 3.0 if you pass --with-x-toolkit=gtk3 | ||
| 2665 | to configure. Note that other libraries used by Emacs, RSVG and GConf, | ||
| 2666 | also depend on Gtk+. You can disable them with --without-rsvg and | ||
| 2667 | --without-gconf. | ||
| 2668 | |||
| 2669 | ** Emacs can be compiled with GnuTLS support. | ||
| 2670 | This happens by default if a suitably recent version of the library is | ||
| 2671 | found at build time. To prevent this, use the configure option | ||
| 2672 | `--without-gnutls'. See below for GnuTLS features. | ||
| 2673 | |||
| 2674 | ** Emacs can be compiled with SELinux support. | ||
| 2675 | This happens by default if a suitably recent version of the library is | ||
| 2676 | found at build time. To prevent this, use the configure option | ||
| 2677 | `--without-selinux'. See below for SELinux features. | ||
| 2678 | |||
| 2679 | ** Emacs can be compiled with ImageMagick support. | ||
| 2680 | This happens by default if a suitably recent version of the library is | ||
| 2681 | found at build time. To prevent this, use the configure option | ||
| 2682 | `--without-imagemagick'. See below for ImageMagick features. | ||
| 2683 | This feature is not available for the Nextstep or MS ports. | ||
| 2684 | |||
| 2685 | ** Emacs can be compiled with libxml2 support. | ||
| 2686 | This happens by default if a suitably recent version of the library is | ||
| 2687 | found at build time. To prevent this, use the configure option | ||
| 2688 | `--without-xml2'. See below for libxml2 features. | ||
| 2689 | |||
| 2690 | ** By default, the installed Info and man pages are compressed. | ||
| 2691 | You can disable this by configuring --without-compress-info. | ||
| 2692 | |||
| 2693 | ** New configure option --with-wide-int. | ||
| 2694 | With it, Emacs integers typically have 62 bits, even on 32-bit machines. | ||
| 2695 | On 32-bit hosts, this raises the limit on buffer sizes from about 512 MiB | ||
| 2696 | to about 2 GiB. | ||
| 2697 | |||
| 2698 | ** New configure options: --with-mmdf, --with-mail-unlink, --with-mailhost. | ||
| 2699 | These provide no new functionality, they just remove the need to edit | ||
| 2700 | lib-src/Makefile by hand in order to use the associated features. | ||
| 2701 | |||
| 2702 | ** New configure option --enable-use-lisp-union-type. | ||
| 2703 | This is only useful for Emacs developers to debug certain types of bugs. | ||
| 2704 | This is not a new feature; only the configure flag is new. | ||
| 2705 | |||
| 2706 | ** The standalone programs digest-doc and sorted-doc are removed. | ||
| 2707 | Emacs now uses Lisp commands `doc-file-to-man' and `doc-file-to-info'. | ||
| 2708 | |||
| 2709 | ** The standalone program `fakemail' is removed. | ||
| 2710 | If you need it, feedmail.el provides a superset of the functionality. | ||
| 2711 | |||
| 2712 | |||
| 2713 | * Startup Changes in Emacs 24.1 | ||
| 2714 | |||
| 2715 | ** The --unibyte, --multibyte, --no-multibyte, and --no-unibyte | ||
| 2716 | command line arguments, and the EMACS_UNIBYTE environment variable, no | ||
| 2717 | longer have any effect. (They were declared obsolete in Emacs 23.) | ||
| 2718 | |||
| 2719 | ** New command line option `--no-site-lisp' removes site-lisp directories | ||
| 2720 | from load-path. -Q now implies this. This option does not affect the | ||
| 2721 | EMACSLOADPATH environment variable (and hence has no effect for | ||
| 2722 | Nextstep builds). | ||
| 2723 | |||
| 2724 | |||
| 2725 | * Changes in Emacs 24.1 | ||
| 2726 | |||
| 2727 | ** Completion | ||
| 2728 | |||
| 2729 | *** Many packages now use the `completion-at-point' command, | ||
| 2730 | rather than implementing separate completion commands. | ||
| 2731 | |||
| 2732 | *** `completion-at-point' now handles tags and semantic completion. | ||
| 2733 | |||
| 2734 | *** Completion in a non-minibuffer now tries to detect the end of completion | ||
| 2735 | and pops down the *Completions* buffer accordingly. | ||
| 2736 | |||
| 2737 | *** New option `completion-cycle-threshold' allows completion cycling. | ||
| 2738 | |||
| 2739 | *** New option `completion-category-overrides' for overriding the | ||
| 2740 | default completion style in certain circumstances. | ||
| 2741 | |||
| 2742 | *** New completion style `substring'. | ||
| 2743 | |||
| 2744 | *** Completion of buffer names uses `substring' completion by default. | ||
| 2745 | |||
| 2746 | *** The option `widget-complete-field' has been removed. | ||
| 2747 | |||
| 2748 | ** Mail changes | ||
| 2749 | |||
| 2750 | *** The first time you try sending mail, Emacs asks for a mail method. | ||
| 2751 | This is implemented by a new default for `send-mail-function', which | ||
| 2752 | is `sendmail-query-once'. This offers to use the smtpmail package, or | ||
| 2753 | to use the old defaults relying on external mail facilities | ||
| 2754 | (`sendmail-send-it' on GNU/Linux and other Unix-like systems, and | ||
| 2755 | `mailclient-send-it' on Windows). | ||
| 2756 | |||
| 2757 | *** Typing `C-c m' in the buffer made by `M-x report-emacs-bug' | ||
| 2758 | transfers the report to your desktop's preferred mail client, if there | ||
| 2759 | is one. This uses either the "xdg-email" utility, or Mac OS's "open" | ||
| 2760 | command. | ||
| 2761 | |||
| 2762 | *** See Changes in Specialized Modes and Packages for SMTPmail changes | ||
| 2763 | and Mail mode changes | ||
| 2764 | |||
| 2765 | ** Emacs server and client changes | ||
| 2766 | |||
| 2767 | *** New option `server-port' specifies the port for TCP Emacs servers. | ||
| 2768 | |||
| 2769 | *** New emacsclient argument -q/--quiet suppresses some status messages. | ||
| 2770 | |||
| 2771 | *** New emacsclient argument --frame-parameters specifies the frame | ||
| 2772 | parameters of any newly-created graphical frame. | ||
| 2773 | |||
| 2774 | *** If emacsclient shuts down due to Emacs signaling an error, | ||
| 2775 | its exit status is 1. | ||
| 2776 | |||
| 2777 | *** New emacsclient argument --parent-id ID. | ||
| 2778 | This opens a client frame in parent X window ID, via XEmbed, similar | ||
| 2779 | to the --parent-id argument to Emacs. | ||
| 2780 | |||
| 2781 | ** Internationalization changes | ||
| 2782 | |||
| 2783 | *** Emacs now supports display and editing of bidirectional text. | ||
| 2784 | Right-to-left (RTL) scripts, such as Arabic, Farsi, and Hebrew, are | ||
| 2785 | displayed in the correct visual order as expected by users of those | ||
| 2786 | scripts. The display reordering is a "full bidirectionality" class | ||
| 2787 | implementation of the Unicode Bidirectional Algorithm (UBA). Buffers | ||
| 2788 | with no RTL text should look exactly the same as before. | ||
| 2789 | |||
| 2790 | **** New buffer-local variable `bidi-display-reordering'. | ||
| 2791 | To disable display reordering in a buffer, change this to nil. | ||
| 2792 | |||
| 2793 | **** New buffer-local variable `bidi-paragraph-direction'. | ||
| 2794 | If nil (the default), Emacs determines the base direction of each | ||
| 2795 | paragraph from its text, as specified by the UBA. Setting the value | ||
| 2796 | to `right-to-left' or `left-to-right' forces a base direction on each | ||
| 2797 | paragraph. | ||
| 2798 | |||
| 2799 | Paragraphs with right-to-left base direction are displayed starting at | ||
| 2800 | the right window edge. | ||
| 2801 | |||
| 2802 | *** Enhanced support for characters with no glyphs in available fonts, | ||
| 2803 | or, on text terminals, characters that cannot be encoded by the | ||
| 2804 | terminal coding system. The new option `glyphless-char-display-control' | ||
| 2805 | specifies how to display them: as a hexadecimal code in a box, a thin | ||
| 2806 | 1-pixel space, an empty box, etc. | ||
| 2807 | |||
| 2808 | *** New input methods for Farsi and Bulgarian | ||
| 2809 | (farsi-isiri-9147, farsi-transliterate-banan, bulgarian-alt-phonetic). | ||
| 2810 | |||
| 2811 | *** `nobreak-char-display' now also highlights Unicode hyphen chars | ||
| 2812 | (U+2010 and U+2011). | ||
| 2813 | |||
| 2814 | *** New Hebrew translation of the Emacs Tutorial. | ||
| 2815 | Type `C-u C-h t' to choose it in case your language setup doesn't | ||
| 2816 | automatically select it. | ||
| 2817 | |||
| 2818 | ** An Emacs Lisp package manager is now included. | ||
| 2819 | This is a convenient way to download and install additional packages, | ||
| 2820 | from a package repository at http://elpa.gnu.org. | ||
| 2821 | |||
| 2822 | *** M-x list-packages shows a list of packages, which can be | ||
| 2823 | selected for installation. | ||
| 2824 | |||
| 2825 | *** New command `describe-package', bound to `C-h P'. | ||
| 2826 | |||
| 2827 | *** By default, all installed packages are loaded automatically when | ||
| 2828 | Emacs starts up. To disable this, set `package-enable-at-startup' to | ||
| 2829 | nil. To specify the packages to load, customize `package-load-list'. | ||
| 2830 | |||
| 2831 | ** Custom theme changes | ||
| 2832 | |||
| 2833 | *** New command `M-x customize-themes', which provides a convenient | ||
| 2834 | interface for enabling and disabling Custom themes. | ||
| 2835 | |||
| 2836 | *** New option `custom-theme-load-path' is the load path for themes. | ||
| 2837 | Emacs no longer looks for Custom themes in `load-path'. The default | ||
| 2838 | value of `custom-theme-load-path' says to look for themes in | ||
| 2839 | `custom-theme-directory', followed by a subdirectory of | ||
| 2840 | `data-directory' named "themes/", which contains a small selection of | ||
| 2841 | built-in Custom themes. | ||
| 2842 | |||
| 2843 | *** New option `custom-safe-themes' records known-safe theme files. | ||
| 2844 | If a theme is not in this list, Emacs queries before loading it, and | ||
| 2845 | offers to save the theme to `custom-safe-themes' automatically. By | ||
| 2846 | default, all themes included in Emacs are treated as safe. | ||
| 2847 | |||
| 2848 | ** Improved GTK integration | ||
| 2849 | |||
| 2850 | *** GTK scroll-bars are now placed on the right by default. | ||
| 2851 | The function `set-scroll-bar-mode' can change this. | ||
| 2852 | |||
| 2853 | *** GTK tool bars can have just text, just images or images and text. | ||
| 2854 | Customize `tool-bar-style' to choose the style. On a Gnome desktop, | ||
| 2855 | the default is taken from desktop settings. | ||
| 2856 | |||
| 2857 | *** GTK tool bars can be placed on any edge of the frame. | ||
| 2858 | The frame-parameter tool-bar-position controls this. It takes the | ||
| 2859 | values top, left, right or bottom. The Options => Show/Hide menu has | ||
| 2860 | entries for this. | ||
| 2861 | |||
| 2862 | *** The default colors for selected text (the `region' face) are taken | ||
| 2863 | from the GTK theme when Emacs is built with GTK. | ||
| 2864 | |||
| 2865 | *** Emacs uses GTK tooltips by default if built with GTK. | ||
| 2866 | You can disable this by changing `x-gtk-use-system-tooltips' to nil. | ||
| 2867 | |||
| 2868 | ** Graphical interface changes | ||
| 2869 | |||
| 2870 | *** On graphical displays, the mode-line no longer ends in dashes. | ||
| 2871 | Also, the first dash (which does not indicate anything) is just | ||
| 2872 | displayed as a space. | ||
| 2873 | |||
| 2874 | *** `menu-bar-select-buffer-function' lets you choose another operation | ||
| 2875 | instead of `switch-to-buffer' when selecting an item in the Buffers menu. | ||
| 2876 | |||
| 2877 | *** Lucid menus and dialogs can display antialiased fonts if Emacs is | ||
| 2878 | built with Xft. These fonts can be set via X resources, for example: | ||
| 2879 | Emacs.pane.menubar.font: Courier-12 | ||
| 2880 | |||
| 2881 | ** Exiting changes | ||
| 2882 | |||
| 2883 | *** Emacs now calls `kill-emacs' if it receives SIGTERM or SIGHUP, | ||
| 2884 | or if it receives a SIGINT signal in batch mode. | ||
| 2885 | |||
| 2886 | *** `kill-emacs-hook' is now also run in batch mode. | ||
| 2887 | Third-party code which adds to `kill-emacs-hook' should check if they | ||
| 2888 | do the right thing in batch mode. | ||
| 2889 | |||
| 2890 | ** Scrolling changes | ||
| 2891 | |||
| 2892 | *** New scrolling commands `scroll-up-command' and `scroll-down-command' | ||
| 2893 | (bound to C-v/[next] and M-v/[prior]) do not signal errors at top/bottom | ||
| 2894 | of buffer at first key-press (instead they move to top/bottom of buffer) | ||
| 2895 | when `scroll-error-top-bottom' is non-nil. | ||
| 2896 | |||
| 2897 | *** New option `scroll-error-top-bottom' (see above). | ||
| 2898 | |||
| 2899 | *** New scrolling commands `scroll-up-line' and `scroll-down-line' | ||
| 2900 | scroll a line instead of full screen. | ||
| 2901 | |||
| 2902 | *** New property `scroll-command' should be set on a command's symbol to | ||
| 2903 | define it as a scroll command affected by `scroll-preserve-screen-position'. | ||
| 2904 | |||
| 2905 | *** If you customize `scroll-conservatively' to a value greater than 100, | ||
| 2906 | Emacs will never recenter point in the window when it scrolls due to | ||
| 2907 | cursor motion commands or commands that move point (e.f., `M-g M-g'). | ||
| 2908 | Previously, you needed to use `most-positive-fixnum' as the value of | ||
| 2909 | `scroll-conservatively' to achieve the same effect. | ||
| 2910 | |||
| 2911 | *** "Aggressive" scrolling now honors the scroll margins. | ||
| 2912 | If you customize `scroll-up-aggressively' or | ||
| 2913 | `scroll-down-aggressively' and move point off the window, Emacs now | ||
| 2914 | scrolls the window so as to avoid positioning point inside the scroll | ||
| 2915 | margin. | ||
| 2916 | |||
| 2917 | ** Basic SELinux support has been added. | ||
| 2918 | This requires Emacs to be linked with libselinux at build time. | ||
| 2919 | |||
| 2920 | *** Emacs preserves the SELinux file context when backing up. | ||
| 2921 | Also, the function `copy-file' has an extra optional argument for | ||
| 2922 | preserving SELinux context, and the return value of `backup-buffer' | ||
| 2923 | now includes the SELinux context. | ||
| 2924 | |||
| 2925 | *** New functions `file-selinux-context' and `set-file-selinux-context' | ||
| 2926 | get and set the SELinux context of a file. | ||
| 2927 | |||
| 2928 | ** Trash changes | ||
| 2929 | |||
| 2930 | *** `delete-by-moving-to-trash' now only affects commands that specify | ||
| 2931 | trashing. This avoids inadvertently trashing temporary files. | ||
| 2932 | |||
| 2933 | *** Calling `delete-file' or `delete-directory' with a prefix argument | ||
| 2934 | now forces true deletion, regardless of `delete-by-moving-to-trash'. | ||
| 2935 | |||
| 2936 | ** File- and directory-local variable changes | ||
| 2937 | |||
| 2938 | *** You can stop directory local vars from applying to subdirectories. | ||
| 2939 | Add an element (subdirs . nil) to the alist portion of any variables | ||
| 2940 | settings to indicate that the section should not apply to | ||
| 2941 | subdirectories. | ||
| 2942 | |||
| 2943 | *** Directory local variables can apply to some file-less buffers. | ||
| 2944 | Affected modes include dired, vc-dir, and log-edit. For example, | ||
| 2945 | adding "(diff-mode . ((mode . whitespace)))" to .dir-locals.el will | ||
| 2946 | turn on `whitespace-mode' for *vc-diff* buffers. Modes should call | ||
| 2947 | `hack-dir-local-variables-non-file-buffer' to support this. | ||
| 2948 | |||
| 2949 | *** Using "mode: MINOR-MODE" to enable a minor mode is deprecated. | ||
| 2950 | Instead, use "eval: (minor-mode 1)". | ||
| 2951 | |||
| 2952 | *** The variable `inhibit-first-line-modes-regexps' has been renamed | ||
| 2953 | to `inhibit-local-variables-regexps'. As the name suggests, it now | ||
| 2954 | applies to ALL file local variables, not just -*- lines. The | ||
| 2955 | associated `inhibit-first-line-modes-suffixes' has been renamed in the | ||
| 2956 | corresponding way. | ||
| 2957 | |||
| 2958 | ** Window changes | ||
| 2959 | |||
| 2960 | *** The `quit-window' command now restores the last buffer displayed | ||
| 2961 | in the quitted window. | ||
| 2962 | |||
| 2963 | *** Resizing an Emacs frame now preserves proportional window sizes, | ||
| 2964 | modulo restrictions like window minimum sizes and fixed-size windows. | ||
| 2965 | |||
| 2966 | *** The behavior of `display-buffer' is now customizable in detail. | ||
| 2967 | |||
| 2968 | **** New option `display-buffer-base-action' specifies a list of | ||
| 2969 | user-determined display "actions" (functions and optional arguments | ||
| 2970 | for choosing the displaying window). | ||
| 2971 | |||
| 2972 | This takes precedence over the default display action, which is | ||
| 2973 | specified by `display-buffer-fallback-action'. | ||
| 2974 | |||
| 2975 | **** New option `display-buffer-alist' maps buffer name regexps to | ||
| 2976 | display actions, taking precedence over `display-buffer-base-action'. | ||
| 2977 | |||
| 2978 | *** New option `window-combination-limit'. | ||
| 2979 | The new option `window-combination-limit' allows to return the space | ||
| 2980 | obtained for resizing or creating a window more reliably to the window | ||
| 2981 | from which such space was obtained. | ||
| 2982 | |||
| 2983 | *** New option `window-combination-resize'. | ||
| 2984 | The new option `window-combination-resize' allows to split a window that | ||
| 2985 | otherwise cannot be split because it's too small by stealing space from | ||
| 2986 | other windows in the same combination. Subsequent resizing or deletion | ||
| 2987 | of the window will resize all windows in the same combination as well. | ||
| 2988 | |||
| 2989 | *** New option `frame-auto-hide-function' lets you choose between | ||
| 2990 | iconifying or deleting a frame when burying a buffer in a dedicated | ||
| 2991 | frame, or quitting a window showing a buffer in a frame of its own. | ||
| 2992 | |||
| 2993 | *** New commands `maximize-window' and `minimize-window'. | ||
| 2994 | These maximize and minimize the size of a window within its frame. | ||
| 2995 | |||
| 2996 | *** New commands `switch-to-prev-buffer' and `switch-to-next-buffer'. | ||
| 2997 | These functions allow to navigate through the live buffers that have | ||
| 2998 | been shown in a specific window. | ||
| 2999 | |||
| 3000 | ** Minibuffer changes | ||
| 3001 | |||
| 3002 | *** The inactive minibuffer has its own major mode `minibuffer-inactive-mode'. | ||
| 3003 | This is handy for minibuffer-only frames, and is also used for the feature | ||
| 3004 | where mouse-1 pops up *Messages*"', which can now easily be changed. | ||
| 3005 | |||
| 3006 | *** Minibuffers set `truncate-lines' to nil. | ||
| 3007 | If you want to change the value to something else, you could use | ||
| 3008 | for example `minibuffer-setup-hook'. | ||
| 3009 | |||
| 3010 | ** `auto-mode-case-fold' is now enabled by default. | ||
| 3011 | |||
| 3012 | ** `backup-by-copying-when-mismatch' now defaults to t. | ||
| 3013 | |||
| 3014 | ** New basic faces `error', `warning', `success'. | ||
| 3015 | These are used to highlight text indicating failure, caution or | ||
| 3016 | successful operation. | ||
| 3017 | |||
| 3018 | ** New option `list-colors-sort' defines the color sort order | ||
| 3019 | for `list-colors-display'. | ||
| 3020 | |||
| 3021 | ** The variable `focus-follows-mouse' now always defaults to nil. | ||
| 3022 | |||
| 3023 | |||
| 3024 | * Editing Changes in Emacs 24.1 | ||
| 3025 | |||
| 3026 | ** Search changes | ||
| 3027 | |||
| 3028 | *** C-y in Isearch is now bound to `isearch-yank-kill', instead of | ||
| 3029 | `isearch-yank-line'. | ||
| 3030 | |||
| 3031 | *** M-y in Isearch is now bound to `isearch-yank-pop', instead of | ||
| 3032 | `isearch-yank-kill'. | ||
| 3033 | |||
| 3034 | *** M-s C-e in Isearch is now bound to `isearch-yank-line'. | ||
| 3035 | |||
| 3036 | ** New commands `count-words-region' and `count-words'. | ||
| 3037 | |||
| 3038 | *** M-= is bound to `count-words-region', not `count-lines-region'. | ||
| 3039 | The `count-words-region' command, when called interactively, reports | ||
| 3040 | the number of lines, words, and characters in the region. It is a | ||
| 3041 | superset of the old `count-lines-region', which is now an obsolete | ||
| 3042 | alias for it. | ||
| 3043 | |||
| 3044 | ** The command `just-one-space' (M-SPC), if given a negative argument, | ||
| 3045 | also deletes newlines around point. | ||
| 3046 | |||
| 3047 | ** Deletion changes | ||
| 3048 | |||
| 3049 | *** New option `delete-active-region'. | ||
| 3050 | If non-nil, [delete] and DEL delete the region if it is active and no | ||
| 3051 | prefix argument is given. If set to `kill', those commands kill | ||
| 3052 | instead. | ||
| 3053 | |||
| 3054 | *** New command `delete-forward-char', bound to [delete]. | ||
| 3055 | This is meant for interactive use, and obeys `delete-active-region'. | ||
| 3056 | The command `delete-char' does not obey `delete-active-region'. | ||
| 3057 | |||
| 3058 | *** `delete-backward-char' is now a Lisp function. | ||
| 3059 | Apart from obeying `delete-active-region', its behavior is unchanged. | ||
| 3060 | However, the byte compiler now warns if it is called from Lisp; Lisp | ||
| 3061 | callers should use delete-char with a negative argument instead. | ||
| 3062 | |||
| 3063 | *** The option `mouse-region-delete-keys' has been deleted. | ||
| 3064 | |||
| 3065 | ** Selection changes. | ||
| 3066 | |||
| 3067 | The default handling of clipboard and primary selections has been | ||
| 3068 | changed to conform with modern X applications. In short, most | ||
| 3069 | commands for killing and yanking text now use the clipboard, while | ||
| 3070 | mouse commands use the primary selection. | ||
| 3071 | |||
| 3072 | In the following, we provide a list of these changes, followed by a | ||
| 3073 | list of steps to get the old behavior back if you prefer that. | ||
| 3074 | |||
| 3075 | *** `select-active-regions' now defaults to t. | ||
| 3076 | Merely selecting text (e.g. with drag-mouse-1) no longer puts it in | ||
| 3077 | the kill ring. The selected text is put in the primary selection, if | ||
| 3078 | the system possesses a separate primary selection facility (e.g. X). | ||
| 3079 | |||
| 3080 | **** `select-active-regions' also accepts a new value, `only'. | ||
| 3081 | This means to only set the primary selection for temporarily active | ||
| 3082 | regions (usually made by mouse-dragging or shift-selection); | ||
| 3083 | "ordinary" active regions, such as those made with C-SPC followed by | ||
| 3084 | point motion, do not alter the primary selection. | ||
| 3085 | |||
| 3086 | **** `mouse-drag-copy-region' now defaults to nil. | ||
| 3087 | |||
| 3088 | *** mouse-2 is now bound to `mouse-yank-primary'. | ||
| 3089 | This pastes from the primary selection, ignoring the kill-ring. | ||
| 3090 | Previously, mouse-2 was bound to `mouse-yank-at-click'. | ||
| 3091 | |||
| 3092 | *** `x-select-enable-clipboard' now defaults to t on all platforms. | ||
| 3093 | |||
| 3094 | *** `x-select-enable-primary' now defaults to nil. | ||
| 3095 | Thus, commands that kill text or copy it to the kill-ring (such as | ||
| 3096 | M-w, C-w, and C-k) also use the clipboard---not the primary selection. | ||
| 3097 | |||
| 3098 | **** The "Copy", "Cut", and "Paste" items in the "Edit" menu are now | ||
| 3099 | exactly equivalent to M-w, C-w, and C-y respectively. | ||
| 3100 | |||
| 3101 | **** Note that on MS-Windows, `x-select-enable-clipboard' was already | ||
| 3102 | non-nil by default, as Windows does not support the primary selection | ||
| 3103 | between applications. | ||
| 3104 | |||
| 3105 | *** To return to the previous behavior, do the following: | ||
| 3106 | |||
| 3107 | **** Change `select-active-regions' to nil. | ||
| 3108 | **** Change `mouse-drag-copy-region' to t. | ||
| 3109 | **** Change `x-select-enable-primary' to t (on X only). | ||
| 3110 | **** Change `x-select-enable-clipboard' to nil. | ||
| 3111 | **** Bind `mouse-yank-at-click' to mouse-2. | ||
| 3112 | |||
| 3113 | *** Support for X cut buffers has been removed. | ||
| 3114 | |||
| 3115 | *** X clipboard managers are now supported. | ||
| 3116 | To inhibit this, change `x-select-enable-clipboard-manager' to nil. | ||
| 3117 | |||
| 3118 | ** New command `C-x r N' (`rectangle-number-lines') numbers the lines | ||
| 3119 | in the current rectangle. With a prefix argument, this prompts for a | ||
| 3120 | number to count from and for a format string. | ||
| 3121 | |||
| 3122 | ** `redisplay-dont-pause' now defaults to t. | ||
| 3123 | This makes Emacs feel more responsive to editing commands that arrive | ||
| 3124 | at high rate, e.g. if you lean on some key, because stopping redisplay | ||
| 3125 | in the middle (when this variable is nil) forces more expensive | ||
| 3126 | updates later on, and Emacs appears to be unable to keep up. | ||
| 3127 | |||
| 3128 | ** The behavior of <TAB> for active regions in Text mode has changed. | ||
| 3129 | In Text and related modes, typing <TAB> (`indent-for-tab-command') | ||
| 3130 | when the region is active causes Emacs to indent all the lines in the | ||
| 3131 | region, aligning them with the line previous to the first line in the | ||
| 3132 | region (or with the left margin if there is no previous line). | ||
| 3133 | |||
| 3134 | ** When `occur' is called with a prefix argument, matching strings are | ||
| 3135 | collected into the `*Occur*' buffer without line numbers. If there | ||
| 3136 | are parenthesized subexpressions in the specified regexp, `occur' | ||
| 3137 | reads replacement text that may contain \\& and \\N whose convention | ||
| 3138 | follows `replace-match'. | ||
| 3139 | |||
| 3140 | |||
| 3141 | * Changes in Specialized Modes and Packages in Emacs 24.1 | ||
| 3142 | |||
| 3143 | ** Archive Mode has basic support for browsing and updating 7z archives. | ||
| 3144 | |||
| 3145 | ** BibTeX mode | ||
| 3146 | |||
| 3147 | *** BibTeX mode now supports biblatex. | ||
| 3148 | Use the variable `bibtex-dialect' to select different BibTeX dialects. | ||
| 3149 | `bibtex-entry-field-alist' is now an obsolete alias for | ||
| 3150 | `bibtex-BibTeX-entry-alist'. | ||
| 3151 | |||
| 3152 | *** New command `bibtex-search-entries', bound to C-c C-a. | ||
| 3153 | |||
| 3154 | *** New `bibtex-entry-format' option `sort-fields', disabled by default. | ||
| 3155 | |||
| 3156 | *** New variable `bibtex-search-entry-globally'. | ||
| 3157 | |||
| 3158 | ** Browse-url | ||
| 3159 | |||
| 3160 | *** New option `browse-url-mailto-function' specifies how to handle "mailto:"s. | ||
| 3161 | |||
| 3162 | *** The default browser used by the package is now the "xdg-open" program, | ||
| 3163 | on platforms that support it. This calls your desktop's preferred browser. | ||
| 3164 | |||
| 3165 | ** Calc | ||
| 3166 | |||
| 3167 | *** Support for musical notes. | ||
| 3168 | |||
| 3169 | *** Support for logarithmic units. | ||
| 3170 | |||
| 3171 | *** No longer uses the tex prefix for TeX specific unit names when | ||
| 3172 | using TeX or LaTeX mode. | ||
| 3173 | |||
| 3174 | *** New option to highlight selections using faces. | ||
| 3175 | |||
| 3176 | *** `calc-histogram' has the option of using a vector to determine the bins. | ||
| 3177 | |||
| 3178 | *** New "O" option prefix. | ||
| 3179 | |||
| 3180 | *** Use the "O" prefix to "d r" (`calc-radix') to turn on twos-complement mode. | ||
| 3181 | |||
| 3182 | ** Calendar, Diary, and Appt | ||
| 3183 | |||
| 3184 | *** Diary entries can contain non-printing "comments". | ||
| 3185 | See the variable `diary-comment-start'. | ||
| 3186 | |||
| 3187 | *** Appointments can specify their individual warning times. | ||
| 3188 | See the variable `appt-warning-time-regexp'. | ||
| 3189 | |||
| 3190 | *** The function specified by `appt-disp-window-function' may be passed | ||
| 3191 | lists of arguments if multiple appointments are due at similar times. | ||
| 3192 | If you are using a custom function for this, you should update it. | ||
| 3193 | |||
| 3194 | *** New function `diary-hebrew-birthday'. | ||
| 3195 | |||
| 3196 | *** Elements of `calendar-day-abbrev-array' and `calendar-month-abbrev-array' | ||
| 3197 | may no longer be nil, but must all be strings. | ||
| 3198 | |||
| 3199 | *** The obsolete (since Emacs 22.1) method of enabling the appt | ||
| 3200 | package by adding `appt-make-list' to `diary-hook' has been removed. | ||
| 3201 | Use `appt-activate' instead. | ||
| 3202 | |||
| 3203 | *** Some appt variables (obsolete since Emacs 22.1) have been removed: | ||
| 3204 | appt-issue-message (use the function appt-activate) | ||
| 3205 | appt-visible/appt-msg-window (use the variable appt-display-format) | ||
| 3206 | |||
| 3207 | *** Some diary function aliases (obsolete since Emacs 22.1) have been removed: | ||
| 3208 | view-diary-entries, list-diary-entries, show-all-diary-entries | ||
| 3209 | |||
| 3210 | ** CC Mode | ||
| 3211 | |||
| 3212 | *** New feature to "guess" the style in an existing buffer. | ||
| 3213 | The main entry point is M-x c-guess. | ||
| 3214 | |||
| 3215 | *** Java Mode now supports Java 5.0 (Tiger) and 6 (Mustang). | ||
| 3216 | |||
| 3217 | *** `c-beginning-of-defun' and `c-end-of-defun' now respect nested scopes. | ||
| 3218 | Thus C-M-a will, by default, go to the beginning of the immediate function, | ||
| 3219 | not the top level. | ||
| 3220 | |||
| 3221 | *** "Macros with semicolons" can be registered for correct indentation. | ||
| 3222 | Where such a macro ends a line (no semicolon) the next statement is no longer | ||
| 3223 | parsed as a statement continuation. | ||
| 3224 | |||
| 3225 | ** Comint and modes derived from it use the standard completion code. | ||
| 3226 | |||
| 3227 | ** Compilation mode | ||
| 3228 | |||
| 3229 | *** Compilation mode can be used without Font Lock mode. | ||
| 3230 | `compilation-parse-errors-function' is now obsolete. | ||
| 3231 | |||
| 3232 | *** New variable `compilation-filter-start', which is bound while | ||
| 3233 | `compilation-filter-hook' runs. It records the start position of the | ||
| 3234 | text inserted by `compilation-filter'. | ||
| 3235 | |||
| 3236 | *** `compilation-error-screen-columns' and `compilation-first-column' | ||
| 3237 | are obeyed in the editing buffer. So programming language modes can | ||
| 3238 | set them, whereas previously only the value in the *Compilation* | ||
| 3239 | buffer was used. | ||
| 3240 | |||
| 3241 | ** Customize | ||
| 3242 | |||
| 3243 | *** Customize buffers now contain a search field. | ||
| 3244 | The search is performed using `customize-apropos'. | ||
| 3245 | To turn off the search field, set `custom-search-field' to nil. | ||
| 3246 | |||
| 3247 | *** Options in customize group buffers start out hidden if not customized. | ||
| 3248 | Use the arrow to the left of the option name to toggle visibility. | ||
| 3249 | |||
| 3250 | *** custom-buffer-sort-alphabetically now defaults to t. | ||
| 3251 | |||
| 3252 | *** The color widget now has a "Choose" button, which allows you to | ||
| 3253 | choose a color via `list-colors-display'. | ||
| 3254 | |||
| 3255 | ** D-Bus | ||
| 3256 | |||
| 3257 | *** It is now possible to access buses other than the default system | ||
| 3258 | or session bus. | ||
| 3259 | |||
| 3260 | *** The `dbus-register-method' and `dbus-register-property' functions | ||
| 3261 | optionally do not register names. | ||
| 3262 | |||
| 3263 | *** The new function `dbus-register-service' registers a known service | ||
| 3264 | name on a D-Bus without also registering a property or a method. | ||
| 3265 | |||
| 3266 | ** Dired-x | ||
| 3267 | |||
| 3268 | *** C-x C-j (`dired-jump') and C-x 4 C-j (`dired-jump-other-window'), | ||
| 3269 | if called with a prefix argument, read a file name from the minibuffer | ||
| 3270 | instead of using the current buffer. | ||
| 3271 | |||
| 3272 | *** The "dired local variables" feature of Dired-x is obsolete. | ||
| 3273 | The standard directory local variables feature replaces it. | ||
| 3274 | |||
| 3275 | ** ERC changes | ||
| 3276 | |||
| 3277 | *** New options `erc-autojoin-timing' and `erc-autojoin-delay', | ||
| 3278 | controlling attempts to autojoin a channel. | ||
| 3279 | |||
| 3280 | *** New variable `erc-coding-system-precedence': If we use `undecided' | ||
| 3281 | as the server coding system, this variable will then be consulted. | ||
| 3282 | The default is to decode strings that can be decoded as utf-8 as | ||
| 3283 | utf-8, and do the normal `undecided' decoding for the rest. | ||
| 3284 | |||
| 3285 | ** Eshell changes | ||
| 3286 | |||
| 3287 | *** The default value of `eshell-directory-name' has changed | ||
| 3288 | to be an "eshell" directory in `user-emacs-directory'. | ||
| 3289 | The old "~/.eshell/" directory is still used if it exists, though. | ||
| 3290 | |||
| 3291 | ** gdb-mi | ||
| 3292 | |||
| 3293 | *** The M-x gdb command now uses the GDB Machine Interface protocol. | ||
| 3294 | It now supports multithread non-stop debugging and simultaneous | ||
| 3295 | debugging of several threads. | ||
| 3296 | |||
| 3297 | ** Image mode | ||
| 3298 | |||
| 3299 | *** RET (`image-toggle-animation') toggles animation, if applicable. | ||
| 3300 | Animation plays once, unless the option `image-animate-loop' is non-nil. | ||
| 3301 | |||
| 3302 | ** Info | ||
| 3303 | |||
| 3304 | *** New command M-x info-display-manual displays a named Info manual. | ||
| 3305 | If that manual is already visited in some Info buffer, it displays | ||
| 3306 | that buffer. (This is handy if you have many manuals in many *info* | ||
| 3307 | buffers, and don't remember the name of the buffer visiting the manual | ||
| 3308 | you want to consult.) Otherwise, it loads and displays the manual. | ||
| 3309 | |||
| 3310 | *** `e' is now bound to `end-of-buffer' rather than to `Info-edit'. | ||
| 3311 | This is for compatibility with the stand-alone Info reader program, | ||
| 3312 | and also because `Info-edit' is a rarely used command that is disabled | ||
| 3313 | by default. | ||
| 3314 | |||
| 3315 | ** Mail mode changes (not Message mode) | ||
| 3316 | |||
| 3317 | *** New command M-x mail-add-attachment for adding MIME attachments | ||
| 3318 | |||
| 3319 | *** The command M-x mail-attach-file was renamed to M-x mail-insert-file. | ||
| 3320 | (Its name is misleading, since it has nothing to do with MIME | ||
| 3321 | attachments.) The old name is now an obsolete alias to the new name. | ||
| 3322 | |||
| 3323 | ** MH-E has been updated to MH-E version 8.3.1. | ||
| 3324 | See MH-E-NEWS for details. | ||
| 3325 | |||
| 3326 | ** Modula-2 mode provides auto-indentation. | ||
| 3327 | |||
| 3328 | ** mpc.el: Can use pseudo tags of the form tag1|tag2 as a union of two tags. | ||
| 3329 | |||
| 3330 | ** nXML mode no longer binds C-RET to `nxml-complete'. | ||
| 3331 | Completion is now performed via `completion-at-point', bound to C-M-i | ||
| 3332 | or M-TAB. If `nxml-bind-meta-tab-to-complete-flag' is non-nil (the | ||
| 3333 | default), this performs tag completion. | ||
| 3334 | |||
| 3335 | ** Org mode has been updated to version 7.8.09. | ||
| 3336 | See ORG-NEWS for details. | ||
| 3337 | |||
| 3338 | ** Prolog mode has been completely revamped, with lots of additional | ||
| 3339 | functionality such as more intelligent indentation, electricity, | ||
| 3340 | support for more variants, including Mercury, and a lot more. | ||
| 3341 | |||
| 3342 | ** Rmail | ||
| 3343 | |||
| 3344 | *** The command `rmail-epa-decrypt' decrypts OpenPGP data | ||
| 3345 | in the Rmail incoming message. | ||
| 3346 | |||
| 3347 | *** The variable `rmail-message-filter' no longer has any effect. | ||
| 3348 | This change was made in Emacs 23.1 but was not advertised at the time. | ||
| 3349 | Try using `rmail-show-message-hook' instead. | ||
| 3350 | |||
| 3351 | ** Shell mode | ||
| 3352 | |||
| 3353 | *** M-x shell prompts for the shell path name if the default directory | ||
| 3354 | is a remote file name and neither the environment variable $ESHELL nor | ||
| 3355 | the variable `explicit-shell-file-name' is set. | ||
| 3356 | |||
| 3357 | *** TAB is now bound to the standard `completion-at-point' command, | ||
| 3358 | which now implements the pcomplete rules for shell command completion. | ||
| 3359 | |||
| 3360 | ** SMTPmail | ||
| 3361 | |||
| 3362 | *** SMTPmail now uses encrypted connections (via STARTTLS) by default | ||
| 3363 | if the mail server supports them. This uses either built-in GnuTLS | ||
| 3364 | support, or the starttls.el library. Customize `smtpmail-stream-type' | ||
| 3365 | to change this. | ||
| 3366 | |||
| 3367 | *** The variable `smtpmail-auth-credentials' has been removed. | ||
| 3368 | By default, the information is now stored in the file ~/.authinfo. | ||
| 3369 | This was the default value of smtpmail-auth-credentials. If you had | ||
| 3370 | customized smtpmail-auth-credentials to a list of user names and | ||
| 3371 | passwords, those settings are not used. During your first connection | ||
| 3372 | to the smtp server, Emacs will prompt for the user name and password, | ||
| 3373 | and offer to save them to ~/.authinfo. Or you can manually copy the | ||
| 3374 | credentials to ~/.authinfo. For example, if you had | ||
| 3375 | |||
| 3376 | (setq smtpmail-auth-credentials | ||
| 3377 | '(("mail.example.org" 25 "jim" "s!cret"))) | ||
| 3378 | |||
| 3379 | then the equivalent line in ~/.authinfo would be | ||
| 3380 | |||
| 3381 | machine mail.example.org port 25 login jim password s!cret | ||
| 3382 | |||
| 3383 | See the auth-source manual for more information, e.g. on encrypting | ||
| 3384 | the credentials file. | ||
| 3385 | |||
| 3386 | *** The variable `smtpmail-starttls-credentials' has been removed. | ||
| 3387 | If you had that set, you need to put | ||
| 3388 | |||
| 3389 | machine smtp.whatever.foo port 25 key "~/.my_smtp_tls.key" cert "~/.my_smtp_tls.cert" | ||
| 3390 | |||
| 3391 | in your ~/.authinfo file instead. | ||
| 3392 | |||
| 3393 | *** SMTPmail defaults to using the address in the From: header as the | ||
| 3394 | SMTP MAIL FROM envelope. To override this, set `mail-envelope-from' | ||
| 3395 | to the address you wish to use instead. | ||
| 3396 | |||
| 3397 | ** SQL mode | ||
| 3398 | |||
| 3399 | *** New options `sql-port', `sql-connection-alist', `sql-send-terminator', | ||
| 3400 | and `sql-oracle-scan-on'. | ||
| 3401 | |||
| 3402 | *** New options controlling prompting for login parameters. | ||
| 3403 | Each supported product has a custom variable `sql-*-login-params', | ||
| 3404 | which is a list of the parameters to be prompted for before a | ||
| 3405 | connection is established. | ||
| 3406 | |||
| 3407 | *** The command `sql-product-interactive' now takes a prefix argument, | ||
| 3408 | which causes it to prompt for an SQL product. | ||
| 3409 | |||
| 3410 | *** Product-specific SQL interactive commands now take prefix arguments. | ||
| 3411 | These commands (`sql-sqlite', `sql-postgres', `sql-mysql', etc.), | ||
| 3412 | given a prefix argument, prompt for a name for the SQL interactive | ||
| 3413 | buffer. This reduces the need for calling `sql-rename-buffer'. | ||
| 3414 | |||
| 3415 | *** SQL interactive modes suppress command continuation prompts, and | ||
| 3416 | replace tabs with spaces. The first change impacts multiple line SQL | ||
| 3417 | statements entered with C-j between each line, statements yanked into | ||
| 3418 | the buffer and statements sent with `sql-send-*' functions. The | ||
| 3419 | second prevents the MySQL and Postgres interpreters from listing | ||
| 3420 | object name completions when sent text via `sql-send-*' functions. | ||
| 3421 | |||
| 3422 | *** New command `sql-connect' starts a predefined SQLi session, | ||
| 3423 | using the login parameters from `sql-connection-alist'. | ||
| 3424 | |||
| 3425 | *** New "Save Connection" menu item in SQLi buffers. | ||
| 3426 | This gathers the login params specified for the SQLi session, if it | ||
| 3427 | was not started by a connection, and saves them as a new connection. | ||
| 3428 | |||
| 3429 | *** New commands for listing database objects and details: | ||
| 3430 | sql-list-all and sql-list-table. | ||
| 3431 | |||
| 3432 | *** An API for manipulating SQL product definitions has been added. | ||
| 3433 | |||
| 3434 | ** TeX modes | ||
| 3435 | |||
| 3436 | *** latex-electric-env-pair-mode keeps \begin..\end matched on the fly. | ||
| 3437 | |||
| 3438 | ** Tramp | ||
| 3439 | |||
| 3440 | *** New inline access method "ksu" (kerberized su). | ||
| 3441 | |||
| 3442 | *** The following access methods are discontinued: "ssh1_old", | ||
| 3443 | "ssh2_old", "scp1_old", "scp2_old", "imap", "imaps" and "fish". | ||
| 3444 | |||
| 3445 | *** The user option `remote-file-name-inhibit-cache' controls whether | ||
| 3446 | remote file attributes are cached for better performance. | ||
| 3447 | |||
| 3448 | *** The option `ange-ftp-binary-file-name-regexp' has changed its | ||
| 3449 | default value to "". | ||
| 3450 | |||
| 3451 | *** Handlers for `file-selinux-context' and `set-file-selinux-context' | ||
| 3452 | for remote machines which support SELinux. | ||
| 3453 | |||
| 3454 | ** New function `url-queue-retrieve', which behaves like url-retrieve, | ||
| 3455 | but with limits (`url-queue-parallel-processes', `url-queue-timeout') on | ||
| 3456 | the degree of parallelism. | ||
| 3457 | |||
| 3458 | ** VC and related modes | ||
| 3459 | |||
| 3460 | *** Support for pulling on distributed version control systems. | ||
| 3461 | The command C-x v + (`vc-pull') runs a "pull" operation, if it is | ||
| 3462 | supported (currently with Bzr, Git, and Mercurial), to update the | ||
| 3463 | current branch and working tree. A prefix argument means to prompt | ||
| 3464 | the user for specifics, e.g. a pull location. | ||
| 3465 | |||
| 3466 | *** `vc-update' is now an alias for `vc-pull'. | ||
| 3467 | |||
| 3468 | *** Support for merging on distributed version control systems. | ||
| 3469 | The command C-x v m (`vc-merge') now runs a "merge" operation, if it | ||
| 3470 | is supported (currently with Bzr, Git, and Mercurial), to merge | ||
| 3471 | changes from another branch into the current one. It prompts for | ||
| 3472 | specifics, e.g. a merge source. | ||
| 3473 | |||
| 3474 | *** New option `vc-revert-show-diff' controls whether `vc-revert' | ||
| 3475 | shows a diff while querying the user. It defaults to t. | ||
| 3476 | |||
| 3477 | *** Log entries in some Log View buffers can be toggled to display a | ||
| 3478 | longer description by typing RET (log-view-toggle-entry-display). | ||
| 3479 | This is currently supported for Bzr, Git, and Mercurial (to support | ||
| 3480 | another backend, define a `log-view-expanded-log-entry-function'). | ||
| 3481 | In the Log View buffers made by C-x v L (`vc-print-root-log'), you can | ||
| 3482 | use this to display the full log entry for the revision at point. | ||
| 3483 | |||
| 3484 | *** New command `vc-ediff' allows visual comparison of two revisions | ||
| 3485 | of a file similar to `vc-diff', but using ediff backend. | ||
| 3486 | |||
| 3487 | *** The option `vc-initial-comment' was removed in Emacs 23.2, but | ||
| 3488 | this was not advertised at the time. | ||
| 3489 | |||
| 3490 | *** `vc-toggle-read-only' is an obsolete alias for `toggle-read-only'. | ||
| 3491 | Since Emacs 23, it has done the same thing as `toggle-read-only', but | ||
| 3492 | this was not advertised at the time. | ||
| 3493 | |||
| 3494 | ** Obsolete modes | ||
| 3495 | |||
| 3496 | *** abbrevlist.el | ||
| 3497 | |||
| 3498 | *** erc-hecomplete.el (use erc-pcomplete.el instead) | ||
| 3499 | |||
| 3500 | *** partial-completion-mode (complete.el) is obsolete. | ||
| 3501 | You can get a comparable behavior with: | ||
| 3502 | (setq completion-styles '(partial-completion initials)) | ||
| 3503 | (setq completion-pcm-complete-word-inserts-delimiters t) | ||
| 3504 | |||
| 3505 | *** pc-mode.el is obsolete (CUA mode is much more comprehensive). | ||
| 3506 | |||
| 3507 | *** pgg is obsolete (use EasyPG instead). | ||
| 3508 | |||
| 3509 | *** sregex.el is obsolete, since rx.el is a strict superset. | ||
| 3510 | |||
| 3511 | *** s-region.el and pc-select.el are obsolete. | ||
| 3512 | They are superseded by shift-select-mode, enabled by default since 23.1. | ||
| 3513 | |||
| 3514 | *** vc-mcvs.el is obsolete (for lack of a maintainer). | ||
| 3515 | |||
| 3516 | ** Miscellaneous | ||
| 3517 | |||
| 3518 | *** The Landmark game is now invoked with `landmark', not `lm'. | ||
| 3519 | Its functions and variables have been similarly renamed. | ||
| 3520 | |||
| 3521 | *** In `ido-file-completion-map', C-v is no longer bound to `ido-toggle-vc'. | ||
| 3522 | (This interfered with cua-mode.) | ||
| 3523 | |||
| 3524 | *** f90.el has some support for Fortran 2008 syntax. | ||
| 3525 | |||
| 3526 | *** `copyright-fix-years' can optionally convert consecutive years to ranges. | ||
| 3527 | |||
| 3528 | *** New command `nato-region' converts text to NATO phonetic alphabet. | ||
| 3529 | |||
| 3530 | |||
| 3531 | * New Modes and Packages in Emacs 24.1 | ||
| 3532 | |||
| 3533 | ** Occur Edit mode applies edits made in *Occur* buffers to the | ||
| 3534 | original buffers. It is bound to "e" in Occur mode. | ||
| 3535 | |||
| 3536 | ** New global minor mode electric-pair-mode. | ||
| 3537 | When enabled, typing an open parenthesis automatically inserts the | ||
| 3538 | matching closing one. | ||
| 3539 | |||
| 3540 | ** New global minor mode electric-indent-mode. | ||
| 3541 | When enabled, typing certain characters triggers reindentation. | ||
| 3542 | Major modes wishing to use this can set electric-indent-chars or | ||
| 3543 | electric-indent-functions. | ||
| 3544 | |||
| 3545 | ** New global minor mode electric-layout-mode. | ||
| 3546 | When enabled, typing certain characters automatically inserts newlines. | ||
| 3547 | Major modes wishing to use this can set electric-layout-rules. | ||
| 3548 | |||
| 3549 | ** tabulated-list.el provides a generic major mode for tabulated data, | ||
| 3550 | from which other modes can be derived. | ||
| 3551 | |||
| 3552 | ** pcase.el provides the ML-style pattern matching macro `pcase'. | ||
| 3553 | |||
| 3554 | ** secrets.el is an implementation of the Secret Service API, an | ||
| 3555 | interface to password managers like GNOME Keyring or KDE Wallet. The | ||
| 3556 | Secret Service API requires D-Bus for communication. The command | ||
| 3557 | `secrets-show-secrets' offers a buffer with a visualization of the | ||
| 3558 | secrets. | ||
| 3559 | |||
| 3560 | ** notifications.el provides an implementation of the Desktop | ||
| 3561 | Notifications API. It requires D-Bus for communication. | ||
| 3562 | |||
| 3563 | ** soap-client.el supports access to SOAP web services from Emacs. | ||
| 3564 | soap-inspect.el is an interactive inspector for SOAP WSDL structures. | ||
| 3565 | |||
| 3566 | ** New generic mode, xmodmap-generic-mode, for xmodmap files. | ||
| 3567 | |||
| 3568 | ** New emacs-lock.el package. | ||
| 3569 | The previous version has been moved to obsolete/old-emacs-lock.el. | ||
| 3570 | Now, there is a proper minor mode `emacs-lock-mode'. Protection | ||
| 3571 | against exiting Emacs and killing the buffer can be set separately. | ||
| 3572 | The mechanism for automatically turning off protection for buffers | ||
| 3573 | with dead inferior processes has been generalized. | ||
| 3574 | |||
| 3575 | |||
| 3576 | * Incompatible Lisp Changes in Emacs 24.1 | ||
| 3577 | |||
| 3578 | ** Passing a nil argument to a minor mode function call now ENABLES | ||
| 3579 | the minor mode unconditionally. This is so that you can write e.g. | ||
| 3580 | |||
| 3581 | (add-hook 'text-mode-hook 'foo-mode) | ||
| 3582 | |||
| 3583 | to enable foo-mode in Text mode buffers, removing the need for | ||
| 3584 | `turn-on-foo-mode' style functions. This affects all mode commands | ||
| 3585 | defined by `define-minor-mode'. If called interactively, the mode | ||
| 3586 | command still toggles the minor mode. | ||
| 3587 | |||
| 3588 | ** The return value of `backup-buffer' has changed. | ||
| 3589 | It is now a list of three elements, where the second element is a list | ||
| 3590 | describing the original file's SELinux context. If Emacs or the | ||
| 3591 | system lacks SELinux support, the context list is (nil nil nil nil). | ||
| 3592 | See "Basic SELinux support" above, under "Changes in Emacs 24.1". | ||
| 3593 | |||
| 3594 | ** `char-direction-table' and the `char-direction' function were deleted. | ||
| 3595 | They were buggy and inferior to the new support of bidirectional | ||
| 3596 | editing introduced in Emacs 24. If you need the bidirectional | ||
| 3597 | properties of a character, use `get-char-code-property' with the last | ||
| 3598 | argument `bidi-class'. | ||
| 3599 | |||
| 3600 | ** `copy-directory' now copies the source directory as a subdirectory | ||
| 3601 | of the target directory, if the latter is an existing directory. The | ||
| 3602 | new optional arg COPY-CONTENTS, if non-nil, makes the function copy | ||
| 3603 | the contents directly into a pre-existing target directory. | ||
| 3604 | |||
| 3605 | ** For mouse click input events in the text area, the Y pixel | ||
| 3606 | coordinate in the POSITION list now counts from the top of the text | ||
| 3607 | area, excluding any header line. Previously, it counted from the top | ||
| 3608 | of the header line. | ||
| 3609 | |||
| 3610 | ** Support for "old-style" backquotes, obsolete for 10+ years, has | ||
| 3611 | been further reduced. Now a backquote not followed by a space is | ||
| 3612 | always treated as a "new-style" backquote. Please remove all | ||
| 3613 | "old-style" backquotes from your code. If your code uses backquotes | ||
| 3614 | as documented in the Elisp manual, and compiles without warning, then | ||
| 3615 | you have nothing to do in this regard. Code not following the | ||
| 3616 | appropriate conventions may fail to compile. | ||
| 3617 | |||
| 3618 | The most common cause of trouble seems to be an old-style backquote | ||
| 3619 | followed by a newline. Another cause of trouble is vector notation | ||
| 3620 | for key sequence notation: instead of [(control ,)] and [(control ')], | ||
| 3621 | you should write [(control ?,)] and [(control ?')], which will work in | ||
| 3622 | older Emacsen too. | ||
| 3623 | |||
| 3624 | ** The macro `eval-at-startup' was removed in Emacs 23.2, but this | ||
| 3625 | was not advertised at the time. The function `custom-initialize-delay' | ||
| 3626 | replaced all known uses. | ||
| 3627 | |||
| 3628 | ** `view-buffer' now treats special mode-class in the same way that | ||
| 3629 | `view-file' has since Emacs 22 (i.e. it won't enable View mode if the | ||
| 3630 | major mode is special). | ||
| 3631 | |||
| 3632 | ** Menu and tool bar changes | ||
| 3633 | |||
| 3634 | *** During startup, Emacs no longer adds entries for `menu-bar-lines' | ||
| 3635 | and `tool-bar-lines' to `default-frame-alist' and `initial-frame-alist'. | ||
| 3636 | With these alist entries omitted, `make-frame' checks the value of the | ||
| 3637 | variable `menu-bar-mode'/`tool-bar-mode' to determine whether to create | ||
| 3638 | a menu-bar or tool-bar, respectively. If the alist entries are added, | ||
| 3639 | they override the value of `menu-bar-mode'/`tool-bar-mode'. | ||
| 3640 | |||
| 3641 | *** The menu bar bindings's caches are not used any more. | ||
| 3642 | Use (where-is-internal <def> nil t) instead. | ||
| 3643 | |||
| 3644 | ** Regions created by mouse dragging are now normal active regions, | ||
| 3645 | similar to those created by shift-selection (see Selection changes | ||
| 3646 | above). In previous Emacs versions, these regions were delineated by | ||
| 3647 | `mouse-drag-overlay'; that variable has been removed. | ||
| 3648 | |||
| 3649 | ** The fourth argument of `filter-buffer-substring' has been removed. | ||
| 3650 | If you want to remove text properties from the final result, simply | ||
| 3651 | pass the result through substring-no-properties. | ||
| 3652 | |||
| 3653 | ** cl.el no longer provides `cl-19'. | ||
| 3654 | |||
| 3655 | ** The following obsolete functions and aliases have been removed | ||
| 3656 | (the appropriate new function is given in parentheses; "not needed" | ||
| 3657 | means you can just remove all calls to the function in question): | ||
| 3658 | |||
| 3659 | *** `comint-kill-output' (`comint-delete-output') | ||
| 3660 | *** `decompose-composite-char' (`char-to-string') | ||
| 3661 | *** `outline-visible' (`outline-invisible-p') | ||
| 3662 | *** `internal-find-face' (`facep') | ||
| 3663 | *** `internal-get-face' (`facep and check-face') | ||
| 3664 | *** `frame-update-faces' (not needed) | ||
| 3665 | *** `frame-update-face-colors' (`frame-set-background-mode') | ||
| 3666 | *** `x-frob-font-weight' and `x-frob-font-slant' (`make-face-*' functions) | ||
| 3667 | *** `x-make-font-bold' and `x-make-font-demibold' (`make-face-bold') | ||
| 3668 | *** `x-make-font-italic' and `x-make-font-oblique' (`make-face-italic') | ||
| 3669 | *** `x-make-font-bold-italic' (`make-face-bold-italic') | ||
| 3670 | *** `x-make-font-unbold' (`make-face-unbold') | ||
| 3671 | *** `x-make-font-unitalic' (`make-face-unitalic') | ||
| 3672 | *** `mldrag-drag-mode-line' (`mouse-drag-mode-line') | ||
| 3673 | *** `mldrag-drag-vertical-line' (`mouse-drag-vertical-line') | ||
| 3674 | *** `iswitchb-default-keybindings' (`iswitchb-mode') | ||
| 3675 | *** `char-bytes' (== 1) | ||
| 3676 | *** `isearch-return-char' (`isearch-printing-char') | ||
| 3677 | *** `make-local-hook' (not needed) | ||
| 3678 | *** `set-screen-height' (`set-frame-height') | ||
| 3679 | *** `set-screen-width' (`set-frame-width') | ||
| 3680 | |||
| 3681 | ** The following obsolete variables and varaliases have been removed | ||
| 3682 | (the appropriate new variable is given in parentheses): | ||
| 3683 | |||
| 3684 | *** `checkdoc-minor-keymap' (`checkdoc-minor-mode-map') | ||
| 3685 | *** `vc-header-alist' (`vc-BACKEND-header') | ||
| 3686 | *** `directory-sep-char' (== ?/) | ||
| 3687 | *** `font-lock-defaults-alist' (`font-lock-defaults') | ||
| 3688 | *** `e' (`float-e'). | ||
| 3689 | |||
| 3690 | ** The following obsolete files were removed: | ||
| 3691 | sc.el, x-menu.el, rnews.el, rnewspost.el | ||
| 3692 | |||
| 3693 | ** The format of the finder-inf.el file has changed, since the Finder | ||
| 3694 | mechanism is now based on the package system. The variable | ||
| 3695 | `finder-package-info' is replaced by `package--builtins' and | ||
| 3696 | `finder-keywords-hash'. | ||
| 3697 | |||
| 3698 | ** When generating autoloads, `update-directory-autoloads' no longer | ||
| 3699 | assumes every inspected file is in your `load-path'. It instead | ||
| 3700 | generates relative names according to the current `load-path'. | ||
| 3701 | |||
| 3702 | |||
| 3703 | * Lisp Changes in Emacs 24.1 | ||
| 3704 | |||
| 3705 | ** Code can now use lexical scoping by default instead of dynamic scoping. | ||
| 3706 | The `lexical-binding' variable enables lexical scoping for local | ||
| 3707 | variables. It is typically set via a file-local variable in the first | ||
| 3708 | line of the file, in which case it applies to all the code in that | ||
| 3709 | file. | ||
| 3710 | |||
| 3711 | *** `eval' takes a new optional argument `lexical' to choose the new lexical | ||
| 3712 | binding instead of the old dynamic binding mode. | ||
| 3713 | |||
| 3714 | *** Lexically scoped interpreted functions are represented with a new form | ||
| 3715 | of function value which looks like (closure ENV ARGS &rest BODY). | ||
| 3716 | |||
| 3717 | *** New macro `letrec' to define recursive local functions. | ||
| 3718 | |||
| 3719 | *** `defvar' and `defconst' now mark the variable as special (dynamic). | ||
| 3720 | So do `defcustom' and other forms that call `defvar' as a subroutine. | ||
| 3721 | |||
| 3722 | *** New function `special-variable-p' to check whether a variable is | ||
| 3723 | declared as dynamically bound. | ||
| 3724 | |||
| 3725 | *** The form ((lambda ...) ...) is deprecated. | ||
| 3726 | |||
| 3727 | ** An Emacs Lisp testing tool is now included. | ||
| 3728 | Emacs Lisp developers can use this tool to write automated tests for | ||
| 3729 | their code. See the ERT info manual for details. | ||
| 3730 | |||
| 3731 | ** Changes for bidirectional display and editing | ||
| 3732 | |||
| 3733 | *** New function `current-bidi-paragraph-direction'. | ||
| 3734 | This returns the base direction of the paragraph at point. | ||
| 3735 | |||
| 3736 | *** New function `bidi-string-mark-left-to-right'. | ||
| 3737 | Given a string containing characters from right-to-left scripts, this | ||
| 3738 | function returns another string which can be safely inserted into a | ||
| 3739 | buffer, such that any following text will be always displayed to the | ||
| 3740 | right of that string. (This works by appending an invisible Unicode | ||
| 3741 | "LEFT-TO-RIGHT MARK" character if the argument string might need it.) | ||
| 3742 | |||
| 3743 | This is useful when the buffer has overall left-to-right paragraph | ||
| 3744 | direction and you need to insert a string whose contents are not known | ||
| 3745 | in advance, without disrupting the layout of the line. | ||
| 3746 | |||
| 3747 | ** Window changes | ||
| 3748 | |||
| 3749 | *** Window tree functions are accessible in Elisp. | ||
| 3750 | Functions are provided to return the parent, siblings or child windows | ||
| 3751 | of any window including internal windows (windows not associated with a | ||
| 3752 | buffer) in the window tree. | ||
| 3753 | |||
| 3754 | **** New function `window-valid-p' gives non-nil for live and internal | ||
| 3755 | windows. | ||
| 3756 | |||
| 3757 | **** Window manipulation can deal with internal windows. | ||
| 3758 | Many window handling functions like `split-window', `delete-window', or | ||
| 3759 | `delete-other-windows' as well as the window resizing functions can now | ||
| 3760 | act on any window including internal ones. | ||
| 3761 | |||
| 3762 | *** window-total-height/-width vs window-body-height/-width. | ||
| 3763 | The function `window-height' has been renamed to `window-total-height' | ||
| 3764 | and `window-width' has been renamed to `window-body-width'. The old | ||
| 3765 | names are provided as aliases. Two new functions `window-total-width' | ||
| 3766 | and `window-body-height' are provided. | ||
| 3767 | |||
| 3768 | *** Window parameters specific to window handling functions. | ||
| 3769 | For each window you can specify a parameter to override the default | ||
| 3770 | behavior of a number of functions like `split-window', `delete-window' | ||
| 3771 | and `delete-other-windows'. The variable `ignore-window-parameters' | ||
| 3772 | allows to ignore processing such parameters. | ||
| 3773 | |||
| 3774 | *** New semantics of third argument of `split-window'. | ||
| 3775 | The third argument of `split-window' has been renamed to SIDE and can be | ||
| 3776 | set to any of the values 'below, 'right, 'above, or 'left to make the | ||
| 3777 | new window appear on the corresponding side of the window that shall be | ||
| 3778 | split. Any other value of SIDE will cause `split-window' to split the | ||
| 3779 | window into two side-by-side windows as before. | ||
| 3780 | |||
| 3781 | *** Window resizing functions. | ||
| 3782 | A new standard function for resizing windows called `window-resize' has | ||
| 3783 | been introduced. This and all other functions for resizing windows no | ||
| 3784 | longer delete any windows when they become too small. | ||
| 3785 | |||
| 3786 | *** Deleting the selected window now selects the most recently selected | ||
| 3787 | live window on that frame instead. | ||
| 3788 | |||
| 3789 | *** `adjust-window-trailing-edge' adjustments. | ||
| 3790 | `adjust-window-trailing-edge' can now deal with fixed-size windows and | ||
| 3791 | is able to resize other windows if a window adjacent to the trailing | ||
| 3792 | edge cannot be shrunk any more. This makes its behavior more similar to | ||
| 3793 | that of Emacs 21 without compromising, however, its inability to delete | ||
| 3794 | windows which was introduced in Emacs 22. | ||
| 3795 | |||
| 3796 | *** Window-local buffer lists. | ||
| 3797 | Windows now have local buffer lists. This means that removing a buffer | ||
| 3798 | from display in a window will preferably show the buffer previously | ||
| 3799 | shown in that window with its previous window-start and window-point | ||
| 3800 | positions. This also means that the same buffer may be automatically | ||
| 3801 | shown twice even if it already appears in another window. | ||
| 3802 | |||
| 3803 | *** `switch-to-buffer' has a new optional argument FORCE-SAME-WINDOW, | ||
| 3804 | which if non-nil requires the buffer to be displayed in the currently | ||
| 3805 | selected window, signaling an error otherwise. If nil, another window | ||
| 3806 | can be used, e.g. if the selected one is strongly dedicated. | ||
| 3807 | |||
| 3808 | *** `split-window-vertically' and `split-window-horizontally' renamed | ||
| 3809 | to `split-window-below' and `split-window-right' respectively. | ||
| 3810 | The old names are kept as aliases. | ||
| 3811 | |||
| 3812 | *** Display actions | ||
| 3813 | |||
| 3814 | **** The second arg to `display-buffer' and `pop-to-buffer' is now | ||
| 3815 | named ACTION, and takes a display action of the same form as | ||
| 3816 | `display-buffer-base-action' (see Changes, above). A non-nil, | ||
| 3817 | non-list value is treated specially, as the old meaning. | ||
| 3818 | |||
| 3819 | **** New variable `display-buffer-overriding-action'. | ||
| 3820 | |||
| 3821 | **** The procedure of `display-buffer' etc. to choose a window is | ||
| 3822 | determined by combining `display-buffer-overriding-action', | ||
| 3823 | `display-buffer-alist', the ACTION arg, `display-buffer-base-action', | ||
| 3824 | and `display-buffer-fallback-action'. The second and fourth of these | ||
| 3825 | are user-customizable variables. | ||
| 3826 | |||
| 3827 | See the docstring of `display-buffer' for details. | ||
| 3828 | |||
| 3829 | *** New functions `window-state-get' and `window-state-put'. | ||
| 3830 | These functions allow to save and restore the state of an arbitrary | ||
| 3831 | frame or window as an Elisp object. | ||
| 3832 | |||
| 3833 | ** Completion | ||
| 3834 | |||
| 3835 | *** New variable `completion-extra-properties' used to specify extra | ||
| 3836 | properties of the current completion: | ||
| 3837 | - :annotate-function, same as the old completion-annotate-function. | ||
| 3838 | - :exit-function, function to call after completion took place. | ||
| 3839 | |||
| 3840 | *** Functions on `completion-at-point-functions' can return any of the | ||
| 3841 | properties valid for `completion-extra-properties'. | ||
| 3842 | |||
| 3843 | *** `completion-annotate-function' is obsolete. | ||
| 3844 | |||
| 3845 | *** New `metadata' method for completion tables. The metadata thus returned | ||
| 3846 | can specify various details of the data returned by `all-completions': | ||
| 3847 | - `category' is the kind of objects returned (e.g., `buffer', `file', ...), | ||
| 3848 | used to select a style in completion-category-overrides. | ||
| 3849 | - `annotation-function' to add annotations in *Completions*. | ||
| 3850 | - `display-sort-function' to specify how to sort entries in *Completions*. | ||
| 3851 | - `cycle-sort-function' to specify how to sort entries when cycling. | ||
| 3852 | |||
| 3853 | *** `minibuffer-local-filename-must-match-map' is not used any more. | ||
| 3854 | Instead, the bindings in `minibuffer-local-filename-completion-map' | ||
| 3855 | are combined with `minibuffer-local-must-match-map'. | ||
| 3856 | |||
| 3857 | *** New variable `completing-read-function' allows overriding the | ||
| 3858 | behavior of `completing-read'. | ||
| 3859 | |||
| 3860 | ** `glyphless-char-display' can now distinguish between graphical and | ||
| 3861 | text terminal display, via a char-table entry that is a cons cell. | ||
| 3862 | |||
| 3863 | ** `pre-command-hook'/`post-command-hook' are not reset to nil on error. | ||
| 3864 | Instead, the offending function is removed. | ||
| 3865 | |||
| 3866 | ** New hook types | ||
| 3867 | |||
| 3868 | *** New function `run-hook-wrapped' for running an abnormal hook by | ||
| 3869 | passing the hook functions as arguments to a "wrapping" function. | ||
| 3870 | Like `run-hook-with-args-until-success', it stops at the first | ||
| 3871 | non-nil return value. | ||
| 3872 | |||
| 3873 | *** New macro `with-wrapper-hook' for running an abnormal hook as a | ||
| 3874 | set of "wrapping" filters, similar to around advice. | ||
| 3875 | (A version of this macro was actually added in Emacs 23.2 but was not | ||
| 3876 | advertised at the time.) | ||
| 3877 | |||
| 3878 | ** Debugger changes | ||
| 3879 | |||
| 3880 | *** New macro `condition-case-unless-debug' (this was actually added in | ||
| 3881 | Emacs 23.1 as condition-case-no-debug, but not advertised) | ||
| 3882 | |||
| 3883 | *** The macro `with-demoted-errors' was added in Emacs 23.1, but not advertised. | ||
| 3884 | |||
| 3885 | *** Variable `stack-trace-on-error' removed. | ||
| 3886 | |||
| 3887 | *** The debugger can now "continue" from an error, which means it will | ||
| 3888 | jump to the error handler as if the debugger had not been invoked | ||
| 3889 | instead of jumping all the way to the top-level. | ||
| 3890 | |||
| 3891 | *** Set `debug-on-event' to enter the debugger on events like SIGUSR1. | ||
| 3892 | This can be useful when `inhibit-quit' is set. | ||
| 3893 | |||
| 3894 | ** The new function `server-eval-at' allows evaluation of Lisp forms on | ||
| 3895 | named Emacs server instances. | ||
| 3896 | |||
| 3897 | ** `call-process' and `call-process-region' allow a `(:file "file")' spec | ||
| 3898 | to redirect STDOUT to a file. | ||
| 3899 | |||
| 3900 | ** The function `format-time-string' now supports the %N directive, | ||
| 3901 | for higher-resolution time stamps. | ||
| 3902 | |||
| 3903 | ** New input reading functions | ||
| 3904 | |||
| 3905 | *** New function `read-char-choice' reads a restricted set of | ||
| 3906 | characters, discarding any inputs not inside the set. | ||
| 3907 | |||
| 3908 | *** The command `read-color' now requires a match for a color name | ||
| 3909 | or RGB triplet, instead of signaling an error if the user provides | ||
| 3910 | invalid input. | ||
| 3911 | |||
| 3912 | **** `facemenu-read-color' is now an alias for `read-color'. | ||
| 3913 | |||
| 3914 | ** `image-library-alist' is renamed to `dynamic-library-alist'. | ||
| 3915 | The variable is now used to load all kind of supported dynamic libraries, | ||
| 3916 | not just image libraries. The previous name is still available as an | ||
| 3917 | obsolete alias. | ||
| 3918 | |||
| 3919 | ** Syntax parsing changes | ||
| 3920 | |||
| 3921 | *** New variable `syntax-propertize-function'. | ||
| 3922 | This replaces `font-lock-syntactic-keywords' which is now obsolete. | ||
| 3923 | This allows syntax-table properties to be set independently from font-lock: | ||
| 3924 | just call syntax-propertize to make sure the text is propertized. | ||
| 3925 | Together with this new variable come a new hook | ||
| 3926 | syntax-propertize-extend-region-functions, as well as two helper functions: | ||
| 3927 | syntax-propertize-via-font-lock to reuse old font-lock-syntactic-keywords | ||
| 3928 | as-is; and syntax-propertize-rules which provides a new way to specify | ||
| 3929 | syntactic rules. | ||
| 3930 | |||
| 3931 | *** Syntax tables support a new "comment style c" additionally to style b. | ||
| 3932 | |||
| 3933 | ** New hook `post-self-insert-hook', run after `self-insert-command'. | ||
| 3934 | |||
| 3935 | ** frame-local variables cannot be let-bound any more. | ||
| 3936 | |||
| 3937 | ** Major and minor mode changes | ||
| 3938 | |||
| 3939 | *** `set-auto-mode' now respects mode: local variables at the end of files, | ||
| 3940 | as well as those in the -*- line. | ||
| 3941 | |||
| 3942 | *** `prog-mode' is a new major mode from which programming modes | ||
| 3943 | should be derived. | ||
| 3944 | |||
| 3945 | **** `prog-mode-hook' can be used to enable features for programming | ||
| 3946 | modes, e.g. (add-hook 'prog-mode-hook 'flyspell-prog-mode) to enable | ||
| 3947 | on-the-fly spell checking for comments and strings. | ||
| 3948 | |||
| 3949 | *** New hook `change-major-mode-after-body-hook', run by | ||
| 3950 | `run-mode-hooks' just before any other mode hooks. | ||
| 3951 | |||
| 3952 | *** Enabled globalized minor modes can be disabled in specific major modes. | ||
| 3953 | If the global mode is global-FOO-mode, then run (FOO-mode -1) in the | ||
| 3954 | major mode's hook, where FOO-mode toggles the mode on a per-buffer basis. | ||
| 3955 | |||
| 3956 | *** `define-minor-mode' accepts new keywords :variable, :after-hook. | ||
| 3957 | |||
| 3958 | ** File-handling changes | ||
| 3959 | |||
| 3960 | *** `delete-file' and `delete-directory' now accept optional arg TRASH. | ||
| 3961 | Trashing is performed if TRASH and `delete-by-moving-to-trash' are | ||
| 3962 | both non-nil. Interactively, TRASH defaults to t, unless a prefix | ||
| 3963 | argument is supplied (see Trash changes, above). | ||
| 3964 | |||
| 3965 | *** New file predicates: `file-equal-p', `file-in-directory-p'. | ||
| 3966 | |||
| 3967 | ** Tool-bars can display separators. | ||
| 3968 | Tool-bar separators are handled like menu separators in menu-bar maps, | ||
| 3969 | i.e. via menu entries of the form `(menu-item "--")'. | ||
| 3970 | |||
| 3971 | ** Image API | ||
| 3972 | |||
| 3973 | *** Animated images support (currently animated gifs only). | ||
| 3974 | |||
| 3975 | **** `image-animated-p' returns non-nil if an image can be animated. | ||
| 3976 | |||
| 3977 | **** `image-animate' animates a supplied image spec. | ||
| 3978 | |||
| 3979 | **** `image-animate-timer' returns the timer object for an image that | ||
| 3980 | is being animated. | ||
| 3981 | |||
| 3982 | *** `image-extension-data' has been renamed to `image-metadata'. | ||
| 3983 | The old name is an obsolete alias to the new one. | ||
| 3984 | |||
| 3985 | *** Image mode can view any image type that ImageMagick supports. | ||
| 3986 | This requires Emacs to be built with ImageMagick support. | ||
| 3987 | |||
| 3988 | **** New function `imagemagick-types', defined if ImageMagick support | ||
| 3989 | is enabled, returns a list of image file extensions that your | ||
| 3990 | ImageMagick installation supports. | ||
| 3991 | |||
| 3992 | **** New function `imagemagick-register-types' enables ImageMagick | ||
| 3993 | image types in Image mode and in `create-image' and other helper | ||
| 3994 | functions. | ||
| 3995 | |||
| 3996 | **** New option `imagemagick-types-inhibit' excludes certain | ||
| 3997 | ImageMagick image types from `imagemagick-register-types'. | ||
| 3998 | |||
| 3999 | **** With ImageMagick support, there are extra Image mode commands to | ||
| 4000 | resize and rotate images: `image-transform-fit-to-height', | ||
| 4001 | `image-transform-fit-to-width', `image-transform-set-rotation', and | ||
| 4002 | `image-transform-set-scale'. | ||
| 4003 | |||
| 4004 | ** `compose-mail' now accepts an optional 8th arg, RETURN-ACTION, and | ||
| 4005 | passes it to the mail user agent function. This argument specifies an | ||
| 4006 | action for returning to the caller after finishing with the mail. For | ||
| 4007 | example, this is used by Rmail to optionally delete a mail window. | ||
| 4008 | |||
| 4009 | ** XML and HTML parsing | ||
| 4010 | If Emacs is compiled with libxml2 support, there are two new | ||
| 4011 | functions: `libxml-parse-html-region' (which parses "real world" HTML) | ||
| 4012 | and `libxml-parse-xml-region' (which parses XML). Both return an | ||
| 4013 | Emacs Lisp parse tree. | ||
| 4014 | |||
| 4015 | ** Networking and encryption changes | ||
| 4016 | |||
| 4017 | *** `open-network-stream' can now be used to open an encrypted stream. | ||
| 4018 | It now accepts an optional `:type' parameter for initiating a TLS | ||
| 4019 | connection, directly or via STARTTLS. To do STARTTLS, additional | ||
| 4020 | parameters (`:end-of-command', `:success', `:capabilities-command') | ||
| 4021 | must also be supplied. | ||
| 4022 | |||
| 4023 | *** New library gnutls.el. | ||
| 4024 | The new function `gnutls-available-p' returns non-nil if Emacs is | ||
| 4025 | built with GnuTLS support. The main entry points are | ||
| 4026 | `open-gnutls-stream' and `gnutls-negotiate'. It's easiest to use | ||
| 4027 | these functions through `open-network-stream', because that can | ||
| 4028 | upgrade connections through STARTTLS opportunistically or use plain | ||
| 4029 | SSL, depending on your needs. For debugging, set `gnutls-log-level' | ||
| 4030 | greater than 0. | ||
| 4031 | |||
| 4032 | *** New primitive `secure-hash' that supports many secure hash algorithms: | ||
| 4033 | md5, sha1, sha2, sha224, sha256, sha384, and sha512. The lisp library | ||
| 4034 | sha1.el has been removed. The `sha1' feature is provided by default. | ||
| 4035 | |||
| 4036 | ** Isearch | ||
| 4037 | |||
| 4038 | *** New hook `isearch-update-post-hook' that runs in `isearch-update'. | ||
| 4039 | |||
| 4040 | ** Progress reporters can now "spin". | ||
| 4041 | The MIN-VALUE and MAX-VALUE arguments of `make-progress-reporter' can | ||
| 4042 | now be nil, or omitted. This makes a "non-numeric" reporter. Each | ||
| 4043 | time you call `progress-reporter-update' on that progress reporter, | ||
| 4044 | with a nil or omitted VALUE argument, the reporter message is | ||
| 4045 | displayed with a "spinning bar". | ||
| 4046 | |||
| 4047 | ** New variable `revert-buffer-in-progress-p' is true while a buffer is | ||
| 4048 | being reverted, even if the buffer has a local `revert-buffer-function'. | ||
| 4049 | |||
| 4050 | ** New variables `delayed-warnings-list' and `delayed-warnings-hook'. | ||
| 4051 | If delayed-warnings-list is non-nil, the command loop calls | ||
| 4052 | `delayed-warnings-hook' after `post-command-hook'. At present, this | ||
| 4053 | is only used by Emacs on some platforms to display warnings during | ||
| 4054 | startup, which might otherwise not be noticed. This uses the | ||
| 4055 | functions `display-delayed-warnings' and `collapse-delayed-warnings'. | ||
| 4056 | |||
| 4057 | ** rx.el has a new `group-n' construct for explicitly numbered groups. | ||
| 4058 | |||
| 4059 | ** New function `make-composed-keymap' that constructs a new keymap | ||
| 4060 | from multiple input maps. You can use this to make a keymap that | ||
| 4061 | inherits from multiple maps, eg: | ||
| 4062 | (set-keymap-parent newmap (make-composed-keymap othermap parent)) | ||
| 4063 | |||
| 4064 | ** New function `string-prefix-p'. | ||
| 4065 | (This was actually added in Emacs 23.2 but was not advertised at the time.) | ||
| 4066 | |||
| 4067 | ** New reader macro ## that stands for the empty symbol. | ||
| 4068 | This means that the empty symbol can now be read back. Also, #: by itself | ||
| 4069 | (when not immediately followed by a possible symbol character) stands for | ||
| 4070 | an empty uninterned symbol. | ||
| 4071 | |||
| 4072 | ** New math functions `isnan', `copysign', `frexp', `ldexp'. | ||
| 4073 | |||
| 4074 | ** The following functions and variables are obsolete: | ||
| 4075 | |||
| 4076 | *** `tooltip-use-echo-area' is obsolete. | ||
| 4077 | Rather than setting this to t, disable Tooltip mode instead. | ||
| 4078 | |||
| 4079 | *** buffer-substring-filters is obsolete. | ||
| 4080 | Use `filter-buffer-substring-functions' instead. | ||
| 4081 | |||
| 4082 | *** `byte-compile-disable-print-circle' is obsolete. | ||
| 4083 | |||
| 4084 | *** `deferred-action-list' and `deferred-action-function' are obsolete. | ||
| 4085 | Use `post-command-hook' instead. | ||
| 4086 | |||
| 4087 | *** `font-lock-maximum-size' is obsolete. | ||
| 4088 | |||
| 4089 | |||
| 4090 | * Changes in Emacs 24.1 on Non-Free Operating Systems | ||
| 4091 | |||
| 4092 | ** On MS Windows, Emacs warns when using the obsolete init file _emacs, | ||
| 4093 | and also when HOME is set to C:\ by default. | ||
| 4094 | |||
| 4095 | ** New configure.bat options | ||
| 4096 | |||
| 4097 | *** --enable-checking builds Emacs with extra runtime checks. | ||
| 4098 | |||
| 4099 | *** --distfiles specifies files to be included in binary distribution. | ||
| 4100 | |||
| 4101 | *** --without-gnutls disables automatic GnuTLS detection. | ||
| 4102 | |||
| 4103 | *** --lib for general library linkage, works with the USER_LIBS build variable. | ||
| 4104 | |||
| 4105 | ** New make target `dist' to create binary distribution for MS Windows. | ||
| 4106 | |||
| 4107 | ** The Lisp function `w32-default-color-map' is now obsolete. | ||
| 4108 | (It is only used internally in the Emacs C code.) | ||
| 4109 | |||
| 4110 | ** Customize ns-auto-hide-menu-bar to have the menu-bar hidden, but | ||
| 4111 | reappear on mouse-over. (Requires OS X 10.6 or later.) | ||
| 4112 | |||
| 4113 | ** On Mac OS X, dragging a file into Emacs visits the file, like on | ||
| 4114 | other platforms, rather than inserting its contents into the buffer. | ||
| 4115 | 334 | ||

| 18 | * Installation Changes in Emacs 24.4 | ||
| 19 | |||
| 20 | ** Emacs can now be compiled with ACL (access control list) support. | ||
| 21 | This happens by default if a suitable support library is found at | ||
| 22 | build time, like libacl on GNU/Linux. To prevent this, use the | ||
| 23 | configure option `--disable-acl'. See below for the features this provides. | ||
| 24 | |||
| 25 | ** Emacs can now be compiled with file notification support. | ||
| 26 | This happens by default if a suitable system library is found at | ||
| 27 | build time. To prevent this, use the configure option | ||
| 28 | `--without-file-notification'. See below for file-notify features. | ||
| 29 | This feature is not available for the Nextstep port. | ||
| 30 | |||
| 31 | ** Emacs can now be compiled with zlib support. | ||
| 32 | This happens by default if zlib is present, which it normally is. | ||
| 33 | To prevent this, use the configure option `--without-zlib'. | ||
| 34 | This provides the function `zlib-decompress-region'; see below for details. | ||
| 35 | |||
| 36 | ** The configure option `--without-compress-info' has been generalized, | ||
| 37 | and renamed to `--without-compress-install'. It now prevents compression | ||
| 38 | of _any_ files during installation. | ||
| 39 | |||
| 40 | ** The configure option `--with-crt-dir' has been removed. | ||
| 41 | It is no longer needed, as the crt*.o files are no longer linked specially. | ||
| 42 | |||
| 43 | ** Directories passed to configure option `--enable-locallisppath' are | ||
| 44 | no longer created during installation. | ||
| 45 | |||
| 46 | ** Emacs for Nextstep (Mac OS X, GNUstep) can be built with ImageMagick support. | ||
| 47 | This requires pkg-config to be available at build time. | ||
| 48 | |||
| 49 | |||
| 50 | * Startup Changes in Emacs 24.4 | ||
| 51 | |||
| 52 | ** When initializing `load-path', an empty element in the EMACSLOADPATH | ||
| 53 | environment variable (either leading, e.g., ":/foo"; trailing, e.g., | ||
| 54 | "/foo:"; or embedded, e.g., "/foo::/bar") is replaced with the default | ||
| 55 | load-path (the one that would have been used if EMACSLOADPATH was unset). | ||
| 56 | This makes it easier to _extend_ the load-path via EMACSLOADPATH | ||
| 57 | (previously, EMACSLOADPATH had to specify the complete load-path, | ||
| 58 | including the defaults). (In older versions of Emacs, an empty element | ||
| 59 | was replaced by ".", so use an explicit "." now if that is what you want.) | ||
| 60 | |||
| 61 | ** The -L option, which normally prepends its argument to load-path, | ||
| 62 | will instead append, if the argument begins with `:' (or `;' on MS Windows; | ||
| 63 | i.e., `path-separator'). | ||
| 64 | |||
| 65 | ** If you use either site-load.el or site-init.el to customize the dumped | ||
| 66 | Emacs executable, any changes to `load-path' that these files make | ||
| 67 | will no longer be present after dumping. To affect a permanent change | ||
| 68 | to `load-path', use the `--enable-locallisppath' option of `configure'. | ||
| 69 | |||
| 70 | ** The user option `initial-buffer-choice' can now specify a function | ||
| 71 | to set up the initial buffer. | ||
| 72 | |||
| 73 | |||
| 74 | * Changes in Emacs 24.4 | ||
| 75 | |||
| 76 | ** Support for ACLs (access control lists). | ||
| 77 | This requires a suitable support library to be found at build time. | ||
| 78 | On GNU/Linux, the POSIX ACL interface is used via libacl. | ||
| 79 | On MS-Windows, the NT Security APIs are used to emulate the POSIX interface. | ||
| 80 | ACLs are extended file attributes, used e.g. for finer-grained permissions. | ||
| 81 | |||
| 82 | *** Emacs preserves the ACL entries of files when backing up. | ||
| 83 | |||
| 84 | *** New functions `file-acl' and `set-file-acl' get and set file ACLs. | ||
| 85 | |||
| 86 | ** Support for menus on text-mode terminals. | ||
| 87 | If the terminal supports a mouse, clicking on the menu bar, or on | ||
| 88 | sensitive portions of the mode line or header line, will drop down the | ||
| 89 | menu defined at that position. Likewise, clicking C-mouse-1, C-mouse-2, or | ||
| 90 | C-mouse-3 on the text area will pop up the menus defined for those locations. | ||
| 91 | |||
| 92 | If the text terminal does not support a mouse, you can activate the | ||
| 93 | first menu-bar menu by typing F10, which invokes `menu-bar-open'. | ||
| 94 | |||
| 95 | If you want the previous behavior, where F10 invoked `tmm-menubar', | ||
| 96 | customize the option `tty-menu-open-use-tmm' to a non-nil value. | ||
| 97 | (Typing M-` always invokes `tmm-menubar', even if `tty-menu-open-use-tmm' | ||
| 98 | is nil.) | ||
| 99 | |||
| 100 | ** New option `load-prefer-newer' affects how the `load' function chooses | ||
| 101 | the file to load. If this is non-nil, then when both .el and .elc | ||
| 102 | versions of a file exist, and the caller did not explicitly specify | ||
| 103 | which one to load, then the newer file is loaded. The default, nil, | ||
| 104 | means to always load the .elc file. | ||
| 105 | |||
| 106 | ** Multi-monitor support | ||
| 107 | |||
| 108 | *** New functions `display-monitor-attributes-list' and | ||
| 109 | `frame-monitor-attributes' can be used to obtain information about | ||
| 110 | each physical monitor on multi-monitor setups. | ||
| 111 | |||
| 112 | *** The functions `display-pixel-width' and `display-pixel-height' now | ||
| 113 | behave consistently among the platforms: they return the pixel width | ||
| 114 | or height for all physical monitors associated with the given display | ||
| 115 | as if they were on X. To get information for each physical | ||
| 116 | monitor, use the new functions above. Similar notes also apply to | ||
| 117 | `x-display-pixel-width', `x-display-pixel-height', `display-mm-width', | ||
| 118 | `display-mm-height', `x-display-mm-width', and `x-display-mm-height'. | ||
| 119 | |||
| 120 | ** New function `zlib-decompress-region', which decompresses gzip- and | ||
| 121 | zlib-format compressed data using built-in zlib support (if available). | ||
| 122 | |||
| 123 | ** The *Messages* buffer is created in `messages-buffer-mode', | ||
| 124 | a new major mode, with read-only status. Any code that might create | ||
| 125 | the *Messages* buffer should call the function `messages-buffer' to do | ||
| 126 | so and set up the mode. | ||
| 127 | |||
| 128 | ** The cursor stops blinking after 10 blinks (by default) on X and Nextstep. | ||
| 129 | You can change the default by customizing `blink-cursor-blinks'. | ||
| 130 | |||
| 131 | ** In keymaps where SPC scrolls forward, S-SPC now scrolls backward. | ||
| 132 | This affects View mode, etc. | ||
| 133 | |||
| 134 | ** The default value of `make-backup-file-name-function' is no longer nil. | ||
| 135 | Instead it defaults to a function that does what the nil value used to. | ||
| 136 | |||
| 137 | ** Help | ||
| 138 | |||
| 139 | *** The command `apropos-variable' is renamed to `apropos-user-option'. | ||
| 140 | `apropos-user-option' shows all user options, while `apropos-variable' | ||
| 141 | shows all variables. When called with a universal prefix argument, | ||
| 142 | the two commands swap their behaviors. When `apropos-do-all' is | ||
| 143 | non-nil, they output the same results. | ||
| 144 | |||
| 145 | *** The key `?' now describes prefix bindings, like `C-h'. | ||
| 146 | |||
| 147 | *** The command `describe-function' has been extended for EIEIO. | ||
| 148 | Running it on constructors will show a full description of the | ||
| 149 | generated class. For generic functions, it will show all | ||
| 150 | implementations together with links to the source. The old commands | ||
| 151 | `describe-class', `describe-constructor' and `describe-generic' were | ||
| 152 | removed. | ||
| 153 | |||
| 154 | *** The function `quail-help' is no longer an interactive command. | ||
| 155 | Use `C-h C-\' (`describe-input-method') instead. | ||
| 156 | |||
| 157 | ** Frame and window handling | ||
| 158 | |||
| 159 | *** New commands `toggle-frame-fullscreen' and `toggle-frame-maximized', | ||
| 160 | bound to <f11> and M-<f10>, respectively. | ||
| 161 | |||
| 162 | *** New hooks `focus-in-hook', `focus-out-hook'. | ||
| 163 | These are normal hooks run when an Emacs frame gains or loses input focus. | ||
| 164 | |||
| 165 | *** The function `window-in-direction' now takes additional arguments | ||
| 166 | for specifying a reference point, wrapping the selection around frame | ||
| 167 | borders, and specifying ways to select the minibuffer window. | ||
| 168 | |||
| 169 | *** Emacs can now change frame sizes in units of pixels, rather than | ||
| 170 | text rows or columns. When maximizing a frame or making it fullscreen, | ||
| 171 | remaining extra pixels are no longer given to the minibuffer, the rightmost | ||
| 172 | fringe, or other unusable space, but are distributed among the text | ||
| 173 | areas of the frame's windows. If the new option `frame-resize-pixelwise' | ||
| 174 | is non-nil, all frame size changes happen pixelwise and set the | ||
| 175 | corresponding size hints for the window manager. | ||
| 176 | |||
| 177 | *** Emacs can now change window sizes in units of pixels. | ||
| 178 | Mouse-dragging a mode line or window divider now changes the size of | ||
| 179 | adjacent windows pixelwise. If the new option `window-resize-pixelwise' | ||
| 180 | is non-nil, functions like `balance-windows-area' and `fit-window-to-buffer' | ||
| 181 | resize windows pixelwise. Most functions for changing or accessing | ||
| 182 | window sizes now have an additional argument that allows changes to apply, | ||
| 183 | or values to be returned, in pixels instead of lines/columns. | ||
| 184 | |||
| 185 | *** The functions `window-body-height' and `window-body-width' now never | ||
| 186 | count partially visible lines or columns if called with a nil PIXELWISE | ||
| 187 | argument. | ||
| 188 | |||
| 189 | *** Emacs can now draw dividers between adjacent windows. To put | ||
| 190 | dividers between side-by-side/vertically stacked windows customize the | ||
| 191 | frame parameters `right-divider-width' and `bottom-divider-width' to | ||
| 192 | some positive integer. You can drag dividers with the mouse (they show | ||
| 193 | a corresponding cursor when the mouse hovers over them). You can change | ||
| 194 | the appearance of dividers by customizing the faces `window-divider', | ||
| 195 | `window-divider-first-pixel', and `window-divider-last-pixel'. The last | ||
| 196 | two are useful to provide a 3D effect, or to better distinguish dividers | ||
| 197 | from surrounding display objects. | ||
| 198 | |||
| 199 | *** New functions to return the pixel sizes of window components, namely | ||
| 200 | `window-scroll-bar-width', `window-mode-line-height', | ||
| 201 | `window-header-line-height', `window-right-divider-width', and | ||
| 202 | `window-bottom-divider-width'. | ||
| 203 | |||
| 204 | *** The new function `window-text-pixel-size' returns the size of the | ||
| 205 | text of a window's buffer in pixels. This allows functions like | ||
| 206 | `fit-frame-to-buffer' and `fit-window-to-buffer' to accurately fit a | ||
| 207 | window to its buffer as it will be displayed. | ||
| 208 | |||
| 209 | *** `fit-window-to-buffer' can now resize windows in both dimensions. | ||
| 210 | This behavior is controlled by the new option | ||
| 211 | `fit-window-to-buffer-horizontally'. The new option | ||
| 212 | `fit-frame-to-buffer' allows you to fit the window's frame to its buffer. | ||
| 213 | |||
| 214 | *** `fit-frame-to-buffer' now fits frames in both dimensions. The new | ||
| 215 | options `fit-frame-to-buffer-margins' and `fit-frame-to-buffer-sizes' | ||
| 216 | control the size of the frame and its position on screen. | ||
| 217 | |||
| 218 | *** Temp Buffer Resize Mode can now adjust the height and width of | ||
| 219 | windows and frames. The new option `temp-buffer-max-width' allows you to | ||
| 220 | control the width of temporary buffer windows. Moreover, if the new | ||
| 221 | option `fit-frame-to-buffer' is non-nil and the buffer appears in the | ||
| 222 | root window of a frame, Temp Buffer Resize Mode will try to adjust the | ||
| 223 | width and/or height of the frame. | ||
| 224 | |||
| 225 | *** `split-window' is now a non-interactive function, not a command. | ||
| 226 | As a command, it was a special case of `C-x 2' (`split-window-below'), | ||
| 227 | and as such superfluous. After being reimplemented in Lisp, its | ||
| 228 | interactive form was mistakenly retained. | ||
| 229 | |||
| 230 | *** The functions `window-size' and `window-total-size' now have an | ||
| 231 | optional argument to return a rounded size value. | ||
| 232 | |||
| 233 | *** `window-state-put' now allows you to put a window state into internal | ||
| 234 | windows too. | ||
| 235 | |||
| 236 | *** New option `scroll-bar-adjust-thumb-portion'. | ||
| 237 | Available only on X, this option allows you to control over-scrolling | ||
| 238 | using the scroll bar (i.e., dragging the thumb down even when the end | ||
| 239 | of the buffer is visible). | ||
| 240 | |||
| 241 | *** New display actions functions for `display-buffer': | ||
| 242 | |||
| 243 | **** `display-buffer-at-bottom' chooses or creates a window at the | ||
| 244 | bottom of the selected frame. | ||
| 245 | |||
| 246 | **** `display-buffer-no-window' to not display the buffer in a window. | ||
| 247 | |||
| 248 | *** New display action alist entry `allow-no-window' to indicate the | ||
| 249 | caller of `display-buffer' is ready to handle the case of not displaying | ||
| 250 | the buffer in a window. | ||
| 251 | |||
| 252 | *** `display-buffer-in-previous-window' is now a member of | ||
| 253 | `display-buffer-fallback-action'. | ||
| 254 | |||
| 255 | ** Lisp evaluation | ||
| 256 | |||
| 257 | *** `eval-defun' on an already defined defcustom calls the :set function, | ||
| 258 | if there is one. | ||
| 259 | |||
| 260 | *** The commands `eval-expression' (`M-:'), `eval-last-sexp' (`C-x C-e'), | ||
| 261 | and `eval-print-last-sexp' (`C-j' in Lisp Interaction mode) can take a | ||
| 262 | zero prefix argument. This disables truncation of lists in the output, | ||
| 263 | equivalent to setting `(eval-expression-)print-length' and | ||
| 264 | `(eval-expression-)print-level' to nil. Additionally, it causes integers | ||
| 265 | to be printed in other formats (octal, hexadecimal, and character). | ||
| 266 | |||
| 267 | *** New hook `eval-expression-minibuffer-setup-hook' run by | ||
| 268 | `eval-expression' on entering the minibuffer. | ||
| 269 | |||
| 270 | ** `cache-long-line-scans' is now non-nil, and renamed to `cache-long-scans', | ||
| 271 | because it affects caching of paragraph scanning results as well. | ||
| 272 | There is no reason to set this to nil except for debugging purposes. | ||
| 273 | |||
| 274 | ** `emacs-bzr-version' has been renamed to `emacs-repository-version', | ||
| 275 | and works for git too, if you fetch the repository notes. | ||
| 276 | |||
| 277 | ** The default value of `comment-use-global-state' is now t, | ||
| 278 | and this variable has been marked obsolete. | ||
| 279 | |||
| 280 | ** `write-region-inhibit-fsync' now defaults to t in batch mode. | ||
| 281 | |||
| 282 | ** The option `set-mark-default-inactive' has been deleted. | ||
| 283 | This unfinished feature was introduced by accident in Emacs 23.1; | ||
| 284 | simply disabling Transient Mark mode does the same thing. | ||
| 285 | |||
| 286 | |||
| 287 | * Editing Changes in Emacs 24.4 | ||
| 288 | |||
| 289 | ** Indentation | ||
| 290 | |||
| 291 | *** `electric-indent-mode' is now enabled by default. | ||
| 292 | Typing RET reindents the current line and indents the new line. | ||
| 293 | `C-j' inserts a newline but does not indent. In some programming modes, | ||
| 294 | additional characters are electric (eg `{'). | ||
| 295 | |||
| 296 | *** New buffer-local `electric-indent-local-mode'. | ||
| 297 | |||
| 298 | *** The behavior of `C-x TAB' (`indent-rigidly') has changed. | ||
| 299 | When invoked without a prefix argument, it now activates a transient | ||
| 300 | mode in which typing <left>, <right>, <S-left>, and <S-right> adjusts | ||
| 301 | the text indentation in the region. Typing any other key resumes | ||
| 302 | normal editing behavior. | ||
| 303 | |||
| 304 | *** `tab-stop-list' is now implicitly extended to infinity by repeating | ||
| 305 | the last step. Its default value is changed to nil, which means a tab | ||
| 306 | stop every `tab-width' columns. | ||
| 307 | |||
| 308 | ** Uniquify is enabled by default, with `post-forward-angle-brackets' style. | ||
| 309 | In other words, if you visit two files that have the same base name, | ||
| 310 | then rather than creating buffers basename and basename<2>, | ||
| 311 | Emacs uses basename<dirA> and basename<dirB>. To change this, | ||
| 312 | customize `uniquify-buffer-name-style'. Set it to nil for the old behavior. | ||
| 313 | |||
| 314 | ** New command `C-x SPC' (`rectangle-mark-mode') makes a rectangular region. | ||
| 315 | Most commands are still unaware of it, but kill/yank do work on the rectangle. | ||
| 316 | |||
| 317 | ** New option `visual-order-cursor-movement'. | ||
| 318 | If this is non-nil, cursor motion with arrow keys will follow the | ||
| 319 | visual order of characters on the screen: <left> always moves to the | ||
| 320 | left, <right> always moves to the right, disregarding the surrounding | ||
| 321 | bidirectional context. | ||
| 322 | |||
| 323 | ** New command `delete-duplicate-lines'. | ||
| 324 | This searches the region for identical lines, and removes all but one | ||
| 325 | copy of each repeated line. The lines need not be sorted. | ||
| 326 | |||
| 327 | ** New command `cycle-spacing' acts like a smarter `just-one-space'. | ||
| 328 | When called in succession, it cycles between spacing conventions: | ||
| 329 | one space, no spaces, original spacing. | ||
| 330 | |||
| 331 | ** `blink-matching-paren' now only highlights the matching open-paren | ||
| 332 | by default, instead of moving the cursor. Set this variable to `jump' to | ||
| 333 | restore the old behavior. | ||
| 334 | |||
| 335 | ** The new function `fill-single-char-nobreak-p' can stop fill from breaking | ||
| 336 | a line after a one-letter word, which is an error in some typographical | ||
| 337 | conventions. To use it, add it to the `fill-nobreak-predicate' hook. | ||
| 338 | |||
| 339 | ** Registers | ||
| 340 | |||
| 341 | *** All interactive commands that read a register (`copy-to-register', etc.) | ||
| 342 | now display a temporary window after `register-preview-delay' seconds | ||
| 343 | that summarizes existing registers. To disable this, set that option to nil. | ||
| 344 | Interactive commands that read registers and want to make use of this | ||
| 345 | should use `register-read-with-preview' to read register names. | ||
| 346 | |||
| 347 | *** New command `frameset-to-register' bound to `C-x r f', replacing | ||
| 348 | `frame-configuration-to-register'. It offers similar functionality, | ||
| 349 | plus enhancements like the ability to restore deleted frames. | ||
| 350 | (`frame-configuration-to-register' still exists, but no longer has a | ||
| 351 | key binding.) | ||
| 352 | |||
| 353 | *** New command `C-x C-k x' (`kmacro-to-register') stores keyboard | ||
| 354 | macros in registers. | ||
| 355 | |||
| 356 | |||
| 357 | * Changes in Specialized Modes and Packages in Emacs 24.4 | ||
| 358 | |||
| 359 | ** Backtrace and debugger | ||
| 360 | |||
| 361 | *** New Lisp debugger command `v' (`debugger-toggle-locals') toggles the | ||
| 362 | display of local variables of the current stack frame. | ||
| 363 | |||
| 364 | *** The Lisp debugger's `e' command (`debugger-eval-expression') now includes | ||
| 365 | the lexical environment when evaluating the code in the context at point | ||
| 366 | (and so allows you to access lexical variables). | ||
| 367 | |||
| 368 | *** New minor mode `jit-lock-debug-mode' helps you debug code run via JIT Lock. | ||
| 369 | |||
| 370 | ** Battery information can now be retrieved from BSD's `apm' utility. | ||
| 371 | |||
| 372 | ** In the Buffer Menu, `M-s a C-o' shows matches for a regexp in marked buffers. | ||
| 373 | |||
| 374 | ** Calc | ||
| 375 | |||
| 376 | *** Calc by default now uses the Gregorian calendar for all dates, and | ||
| 377 | uses January 1, 1 AD as its day number 1. Previously Calc used the | ||
| 378 | Julian calendar for dates before September 14, 1752, and it used | ||
| 379 | December 31, 1 BC as its day number 1; the new scheme is more | ||
| 380 | consistent with Calendar's calendrical system and day numbering. | ||
| 381 | |||
| 382 | *** The new option `calc-gregorian-switch' lets you configure if | ||
| 383 | (and when) Calc switches from the Julian to the Gregorian calendar. | ||
| 384 | |||
| 385 | *** Support for ISO 8601 dates. | ||
| 386 | |||
| 387 | ** Calendar and Diary | ||
| 388 | |||
| 389 | *** New faces `calendar-weekday-header', `calendar-weekend-header', | ||
| 390 | and `calendar-month-header'. | ||
| 391 | |||
| 392 | *** New option `calendar-day-header-array'. | ||
| 393 | |||
| 394 | *** New variable `diary-from-outlook-function', used by the command | ||
| 395 | `diary-from-outlook'. | ||
| 396 | |||
| 397 | *** The variable `calendar-font-lock-keywords' is obsolete. | ||
| 398 | |||
| 399 | ** CEDET | ||
| 400 | |||
| 401 | *** EDE | ||
| 402 | |||
| 403 | **** The cpp-root project now supports executing a compile command. | ||
| 404 | It can be set through the new :compile-command slot or the | ||
| 405 | buffer-local variable `compile-command'. | ||
| 406 | |||
| 407 | **** Better selection of include directories for the 'linux' project. | ||
| 408 | Include directories now support out-of-tree build directories and | ||
| 409 | target architecture auto-detection. | ||
| 410 | |||
| 411 | *** Semantic | ||
| 412 | |||
| 413 | **** Improved detection of used namespaces in current scope in C++. | ||
| 414 | |||
| 415 | **** Parsing of default values for variables and function arguments in C/C++. | ||
| 416 | They are also displayed by the summarize feature in the mode line. | ||
| 417 | |||
| 418 | **** Improved parsing of function pointers in C/C++. | ||
| 419 | This also includes parsing of function pointers as function arguments. | ||
| 420 | |||
| 421 | **** Parsing of C/C++ preprocessor macros that open new scope. | ||
| 422 | For example, this enables parsing of macros that open new namespaces. | ||
| 423 | |||
| 424 | **** Support for 'this' pointer in inline member functions in C++. | ||
| 425 | |||
| 426 | ** CFEngine mode | ||
| 427 | |||
| 428 | *** Support for completion, ElDoc, and Flycheck has been added. | ||
| 429 | |||
| 430 | *** The current CFEngine syntax is parsed from "cf-promises -s json". | ||
| 431 | There is a fallback syntax available if you don't have cf-promises or | ||
| 432 | if your version doesn't support that option. See option `cfengine-cf-promises'. | ||
| 433 | |||
| 434 | ** cl-lib | ||
| 435 | |||
| 436 | *** New macro `cl-tagbody'. | ||
| 437 | This executes statements while allowing for control transfer to labels. | ||
| 438 | |||
| 439 | *** letf is now just an alias for cl-letf. | ||
| 440 | |||
| 441 | ** CUA mode | ||
| 442 | |||
| 443 | *** CUA mode now uses `delete-selection-mode' and `shift-select-mode'. | ||
| 444 | Hence, you can now enable it independently from those modes, and from | ||
| 445 | `transient-mark-mode'. | ||
| 446 | |||
| 447 | *** `cua-highlight-region-shift-only' is now obsolete. | ||
| 448 | You can disable `transient-mark-mode' to get the same result. | ||
| 449 | |||
| 450 | *** CUA's rectangles can now be used without CUA by calling the command | ||
| 451 | `cua-rectangle-mark-mode'. | ||
| 452 | |||
| 453 | ** Delete Selection mode can now be used without Transient Mark mode. | ||
| 454 | |||
| 455 | ** Desktop | ||
| 456 | |||
| 457 | *** `desktop-save-mode' by default now auto-saves an existing desktop file | ||
| 458 | after `desktop-auto-save-timeout'. To disable this, customize that option | ||
| 459 | to nil (or zero). | ||
| 460 | |||
| 461 | *** Desktop now saves and restores the frame/window configuration. | ||
| 462 | To disable this, set `desktop-restore-frames' to nil. | ||
| 463 | See also related options `desktop-restore-reuses-frames', | ||
| 464 | `desktop-restore-in-current-display', and `desktop-restore-forces-onscreen'. | ||
| 465 | |||
| 466 | ** New Dired minor mode `dired-hide-details-mode' toggles whether details, | ||
| 467 | such as file ownership or permissions, are visible in Dired buffers. | ||
| 468 | See the new options `dired-hide-details-hide-symlink-targets' and | ||
| 469 | `dired-hide-details-hide-information-lines' for customizing what to hide. | ||
| 470 | |||
| 471 | ** You can enable ElDoc inside the `eval-expression' minibuffer with: | ||
| 472 | (add-hook 'eval-expression-minibuffer-setup-hook 'eldoc-mode) | ||
| 473 | The results display in the mode line. | ||
| 474 | |||
| 475 | ** Electric Pair mode | ||
| 476 | |||
| 477 | *** New option `electric-pair-preserve-balance', enabled by default. | ||
| 478 | If non-nil, pairing/skipping only kicks in when that help the balance | ||
| 479 | of parentheses and quotes; i.e., the buffer should end up at least as | ||
| 480 | balanced as before. | ||
| 481 | |||
| 482 | You can further control this behavior by adjusting the predicates | ||
| 483 | stored in `electric-pair-inhibit-predicate' and `electric-pair-skip-self'. | ||
| 484 | |||
| 485 | *** New option `electric-pair-delete-adjacent-pairs', enabled by default. | ||
| 486 | In `electric-pair-mode', the commands `backward-delete-char' and | ||
| 487 | `backward-delete-char-untabify' are now bound to electric variants | ||
| 488 | that delete the closer when invoked between adjacent pairs. | ||
| 489 | |||
| 490 | *** New option `electric-pair-open-newline-between-pairs', enabled by default. | ||
| 491 | In `electric-pair-mode', inserting a newline between adjacent pairs | ||
| 492 | opens an extra newline after point, which is indented if | ||
| 493 | `electric-indent-mode' is also set. | ||
| 494 | |||
| 495 | *** New option `electric-pair-skip-whitespace', enabled by default. | ||
| 496 | This controls if skipping over closing delimiters should jump over any | ||
| 497 | whitespace slack. Setting it to `chomp' makes it delete this | ||
| 498 | whitespace. See also the variable `electric-pair-skip-whitespace-chars'. | ||
| 499 | |||
| 500 | *** New variables control the pairing in strings and comments. | ||
| 501 | You can customize `electric-pair-text-pairs' and | ||
| 502 | `electric-pair-text-syntax-table' to tweak pairing behavior inside | ||
| 503 | strings and comments. | ||
| 504 | |||
| 505 | ** New EPA option `epa-mail-aliases'. | ||
| 506 | You can set this to a list of email address aliases that `epa-mail-encrypt' | ||
| 507 | should use to find keys. | ||
| 508 | |||
| 509 | ** New ERC option `erc-accidental-paste-threshold-seconds'. | ||
| 510 | If set to a number, this can be used to avoid accidentally pasting large | ||
| 511 | amounts of data into the ERC input. | ||
| 512 | |||
| 513 | ** New ERT macro `skip-unless' allows skipping ERT tests. | ||
| 514 | |||
| 515 | ** Eshell | ||
| 516 | |||
| 517 | *** `eshell' now supports visual subcommands and options. | ||
| 518 | Eshell has been able to handle "visual" commands (interactive, | ||
| 519 | non-line oriented commands such as top that require display | ||
| 520 | capabilities not provided by eshell) by running them in an Emacs | ||
| 521 | terminal emulator. See `eshell-visual-commands'. | ||
| 522 | |||
| 523 | This feature has been extended to subcommands and options that make a | ||
| 524 | usually line-oriented command a visual command. Typical examples are | ||
| 525 | "git log" and "git <command> --help", which display their output in a | ||
| 526 | pager by default. See `eshell-visual-subcommands' and `eshell-visual-options'. | ||
| 527 | |||
| 528 | *** New Eshell-Tramp module. | ||
| 529 | External su and sudo commands are now the default; the internal, | ||
| 530 | Tramp-using variants can still be used by enabling the eshell-tramp module. | ||
| 531 | |||
| 532 | ** New F90 mode option `f90-smart-end-names'. | ||
| 533 | |||
| 534 | ** New option `gnutls-verify-error', if non-nil, means that Emacs | ||
| 535 | should reject SSL/TLS certificates that GnuTLS determines as invalid. | ||
| 536 | (This option defaults to nil at present, but this is expected to change | ||
| 537 | in a future release.) | ||
| 538 | |||
| 539 | ** Hi-Lock | ||
| 540 | |||
| 541 | *** New global command `M-s h .' (`highlight-symbol-at-point') highlights | ||
| 542 | the symbol near point. | ||
| 543 | |||
| 544 | *** New option `hi-lock-auto-select-face'. When non-nil, hi-lock commands | ||
| 545 | will cycle through faces in `hi-lock-face-defaults' without prompting. | ||
| 546 | |||
| 547 | ** Icomplete is now more similar to Ido. | ||
| 548 | |||
| 549 | *** Icomplete by default now applies to all forms of minibuffer completion. | ||
| 550 | The variable `icomplete-with-completion-tables' (now a user option) | ||
| 551 | controls this. To restore the old behavior, set it back to | ||
| 552 | '(internal-complete-buffer). | ||
| 553 | |||
| 554 | *** You can navigate through and select completions using the keys | ||
| 555 | from `icomplete-minibuffer-map'. | ||
| 556 | |||
| 557 | *** The string that separates potential completions is now a customizable | ||
| 558 | option (`icomplete-separator'). The default is " | " rather than ",". | ||
| 559 | |||
| 560 | *** New face `icomplete-first-match'; and new options | ||
| 561 | `icomplete-hide-common-prefix' and `icomplete-show-matches-on-no-input'. | ||
| 562 | |||
| 563 | *** The option `icomplete-show-key-bindings' has been removed. | ||
| 564 | |||
| 565 | ** Ido | ||
| 566 | |||
| 567 | *** An Ido user manual is now included. | ||
| 568 | |||
| 569 | *** The option `ido-use-virtual-buffers' can now take the value `auto'. | ||
| 570 | This means to use virtual buffers if the current ido input does not match | ||
| 571 | an existing buffer. | ||
| 572 | |||
| 573 | *** The variable `ido-decorations' can optionally have two new elements, | ||
| 574 | which are the brackets to use around the sole remaining completion. | ||
| 575 | |||
| 576 | ** Image mode | ||
| 577 | |||
| 578 | *** New commands `n' (`image-next-file') and `p' (`image-previous-file') | ||
| 579 | visit the next image file and the previous image file in the same | ||
| 580 | directory, respectively. | ||
| 581 | |||
| 582 | *** New commands to show specific frames of multi-frame images. | ||
| 583 | `f' (`image-next-frame') and `b' (`image-previous-frame') visit the | ||
| 584 | next or previous frame. `F' (`image-goto-frame') shows a specific frame. | ||
| 585 | |||
| 586 | *** New commands to speed up, slow down, or reverse animation. | ||
| 587 | `a +' (`image-increase-speed') and `a -' (`image-decrease-speed') to | ||
| 588 | speed up and slow down the animation. `a r' (`image-reverse-speed') | ||
| 589 | to reverse it and `a 0' (`image-reset-speed') to reset it. | ||
| 590 | |||
| 591 | *** The command `image-mode-fit-frame' deletes other windows. | ||
| 592 | When toggling, it restores the frame's previous window configuration. | ||
| 593 | It also has an optional frame argument, which can be used by Lisp | ||
| 594 | callers to fit the image to a frame other than the selected frame. | ||
| 595 | |||
| 596 | ** New Imenu option `imenu-generic-skip-comments-and-strings'. | ||
| 597 | |||
| 598 | ** Info | ||
| 599 | |||
| 600 | *** New Info face `info-index-match', used to highlight matches in index | ||
| 601 | entries displayed by `Info-index-next', `Info-virtual-index' and | ||
| 602 | `info-apropos'. | ||
| 603 | |||
| 604 | *** The Info-edit command is obsolete. Editing Info nodes by hand | ||
| 605 | has not been relevant for some time. | ||
| 606 | |||
| 607 | ** JS Mode | ||
| 608 | |||
| 609 | *** New option `js-switch-indent-offset'. | ||
| 610 | |||
| 611 | *** Better indentation of multiple-variable declarations. | ||
| 612 | If a declaration spans several lines, variables on the following lines | ||
| 613 | are lined up to the first one. | ||
| 614 | |||
| 615 | *** Recognition and better indentation of continuations in array comprehensions. | ||
| 616 | |||
| 617 | ** MH-E has been updated to version 8.6 - see separate MH-E-NEWS file. | ||
| 618 | |||
| 619 | ** Octave mode | ||
| 620 | |||
| 621 | *** Font locking for Texinfo comments and new keywords. | ||
| 622 | |||
| 623 | *** Completion in Octave file buffers. | ||
| 624 | |||
| 625 | *** ElDoc support. | ||
| 626 | |||
| 627 | *** Jump to definition. | ||
| 628 | |||
| 629 | *** Documentation lookup/search. | ||
| 630 | |||
| 631 | ** OPascal mode is the new name for Delphi mode | ||
| 632 | |||
| 633 | *** All delphi-* variables and functions have been renamed to opascal-*. | ||
| 634 | Obsolete aliases exist for those likely to have been used externally. | ||
| 635 | |||
| 636 | *** The option `delphi-newline-always-indents' has been removed. | ||
| 637 | Use `electric-indent-mode' instead. | ||
| 638 | |||
| 639 | *** The TAB key runs the standard `indent-for-tab-command', not `delphi-tab'. | ||
| 640 | |||
| 641 | ** Package | ||
| 642 | |||
| 643 | *** The package library now supports digital signing of packages. | ||
| 644 | Maintainers of package archives should consider signing their packages | ||
| 645 | to enhance security. | ||
| 646 | |||
| 647 | **** If the user option `package-check-signature' is non-nil, | ||
| 648 | Emacs tries to check package signatures at install time. | ||
| 649 | The value `allow-unsigned' allows installation of unsigned packages. | ||
| 650 | |||
| 651 | **** The user option `package-unsigned-archives' lists archives where | ||
| 652 | Emacs will not try to check signatures. | ||
| 653 | |||
| 654 | *** New option `package-pinned-packages'. This is useful if you have multiple | ||
| 655 | archives enabled, with more than one offering a given package that you want. | ||
| 656 | |||
| 657 | *** In the `list-packages' buffer, you can use `f' (`package-menu-filter') | ||
| 658 | to filter the list of packages by a keyword. | ||
| 659 | |||
| 660 | *** In the `describe-package' buffer, there are now buttons listing the | ||
| 661 | keywords related to the package. Click on a button to see other packages | ||
| 662 | related to that keyword. | ||
| 663 | |||
| 664 | *** The format of `archive-contents' files, generated by package | ||
| 665 | repositories, has changed to allow a new (fifth) element in the data | ||
| 666 | vectors, containing an associative list with extra properties. | ||
| 667 | (For example, `describe-package' uses the `:url' extra property to | ||
| 668 | display a "Homepage" header.) | ||
| 669 | |||
| 670 | ** In Prolog mode, `prolog-use-smie' has been removed, | ||
| 671 | along with the non-SMIE indentation code. | ||
| 672 | |||
| 673 | ** Python mode | ||
| 674 | |||
| 675 | *** Out of the box support for CPython, iPython and readline based shells. | ||
| 676 | **** `python-shell-completion-module-string-code' is no longer used. | ||
| 677 | |||
| 678 | *** Automatic shell prompt detection. New user options: | ||
| 679 | **** `python-shell-interpreter-interactive-arg'. | ||
| 680 | **** `python-shell-prompt-detect-enabled'. | ||
| 681 | **** `python-shell-prompt-detect-failure-warning'. | ||
| 682 | **** `python-shell-prompt-input-regexps'. | ||
| 683 | **** `python-shell-prompt-output-regexps'. | ||
| 684 | |||
| 685 | *** Python shell support for remote hosts via tramp. | ||
| 686 | |||
| 687 | *** Correct display of line numbers for code sent to the Python shell. | ||
| 688 | |||
| 689 | ** Remember | ||
| 690 | |||
| 691 | *** The new command `remember-notes' creates a buffer that is saved on exit. | ||
| 692 | You can use it as a more permanent *scratch* buffer. | ||
| 693 | |||
| 694 | *** Remember can now store notes in separate files. | ||
| 695 | To use this, add `remember-store-in-files' to the `remember-handler-functions' | ||
| 696 | option. The files are saved in `remember-data-directory' using | ||
| 697 | names specified by `remember-directory-file-name-format'. | ||
| 698 | |||
| 699 | ** Rmail | ||
| 700 | |||
| 701 | *** Customize `rmail-mbox-format' to influence some minor aspects of | ||
| 702 | how Rmail displays non-MIME messages. | ||
| 703 | |||
| 704 | *** The `unrmail' command now converts from BABYL to mboxrd format, | ||
| 705 | rather than mboxo. Customize `unrmail-mbox-format' to change this. | ||
| 706 | |||
| 707 | ** Ruby mode | ||
| 708 | |||
| 709 | *** Improved syntax highlighting and indentation. | ||
| 710 | |||
| 711 | *** New `electric-indent-mode' integration. | ||
| 712 | |||
| 713 | *** New option `ruby-encoding-magic-comment-style'. | ||
| 714 | |||
| 715 | *** New option `ruby-custom-encoding-magic-comment-template'. | ||
| 716 | |||
| 717 | *** New option `ruby-align-to-stmt-keywords'. | ||
| 718 | |||
| 719 | *** New option `ruby-align-chained-calls'. | ||
| 720 | |||
| 721 | *** More Ruby file types have been added to `auto-mode-alist'. | ||
| 722 | |||
| 723 | ** Search and Replace | ||
| 724 | |||
| 725 | *** New global command `M-s .' (`isearch-forward-symbol-at-point') | ||
| 726 | starts a symbol (identifier) incremental search forward with the | ||
| 727 | symbol found near point added to the search string initially. | ||
| 728 | |||
| 729 | *** `C-x 8 RET' in Isearch mode reads a character by its Unicode name | ||
| 730 | and adds it to the search string. | ||
| 731 | |||
| 732 | *** `M-s i' in Isearch mode toggles whether search matches invisible text. | ||
| 733 | |||
| 734 | *** `query-replace' skips invisible text when `search-invisible' is nil, | ||
| 735 | and opens overlays with hidden text when `search-invisible' is `open'. | ||
| 736 | |||
| 737 | *** A negative prefix argument of replacement commands replaces backward. | ||
| 738 | `M-- M-%' replaces a string backward, `M-- C-M-%' replaces a regexp | ||
| 739 | backward, `M-s w words M-- M-%' replaces a sequence of words backward. | ||
| 740 | |||
| 741 | *** By default, prefix arguments do not now terminate Isearch mode. | ||
| 742 | Set `isearch-allow-prefix' to nil to restore the old behavior. | ||
| 743 | |||
| 744 | *** More Isearch commands accept prefix arguments, namely | ||
| 745 | `isearch-printing-char', `isearch-quote-char', `isearch-yank-word', | ||
| 746 | `isearch-yank-line'. | ||
| 747 | |||
| 748 | *** Word search now matches whitespace at the beginning/end | ||
| 749 | of the search string if it contains leading/trailing whitespace. | ||
| 750 | In an incremental word search or when using a non-nil LAX argument | ||
| 751 | of `word-search-regexp', the lax matching can also match part of | ||
| 752 | the first word (in addition to the lax matching of the last word). | ||
| 753 | The same rules are now applied to the symbol search, with the difference | ||
| 754 | that it matches symbols, and non-symbol characters between symbols. | ||
| 755 | |||
| 756 | ** New SES command `ses-rename-cell' allows assignment of names to SES cells. | ||
| 757 | |||
| 758 | ** The shell.el option `explicit-bash-args' includes --noediting by default. | ||
| 759 | All non-ancient Bash versions support this option. | ||
| 760 | |||
| 761 | ** Shell Script mode | ||
| 762 | |||
| 763 | *** The SMIE indentation engine is now used by default - see `sh-use-smie'. | ||
| 764 | |||
| 765 | *** `sh-mode' now has its own setting for `add-log-current-defun-function'. | ||
| 766 | |||
| 767 | ** SMIE | ||
| 768 | |||
| 769 | *** You can customize the SMIE indentation of a mode via `smie-config'. | ||
| 770 | The command `smie-config-guess' can help you derive the appropriate | ||
| 771 | indentation settings, if you provide it with an indented sample file. | ||
| 772 | Use `smie-config-save' to save the result. | ||
| 773 | |||
| 774 | *** You can customize the SMIE indentation of a file by adding an entry to | ||
| 775 | the file's local variables of the form: `eval: (smie-config-local '(RULES))'. | ||
| 776 | |||
| 777 | *** New commands `smie-config-show-indent' and `smie-config-set-indent'. | ||
| 778 | |||
| 779 | ** SQL mode | ||
| 780 | |||
| 781 | *** Improved login monitoring and appropriate response to login failures. | ||
| 782 | New variable `sql-login-delay' defines maximum wait time for a connection. | ||
| 783 | |||
| 784 | *** Oracle support. | ||
| 785 | SQL*Plus script placeholders are properly highlighted and identified | ||
| 786 | in `sql-placeholders-filter'. When starting SQL*Plus, `sql-oracle-options' | ||
| 787 | are passed before the logon parameter, as required. The default now | ||
| 788 | includes `-L', to limit the number of logon attempts per invocation. | ||
| 789 | |||
| 790 | ** New Term mode option `term-suppress-hard-newline'. | ||
| 791 | |||
| 792 | ** Todo mode has been rewritten and enhanced. | ||
| 793 | The Todo mode user manual describes all commands and most user | ||
| 794 | options. To support some of these features, a new file format is | ||
| 795 | used, which is incompatible with the old format; however, you can | ||
| 796 | convert old todo and done item files to the new format on initializing | ||
| 797 | the first new todo file, or at any later time with the provided | ||
| 798 | conversion command. The previous version of todo-mode.el has been | ||
| 799 | renamed to otodo-mode.el and is now obsolete. New features include: | ||
| 800 | |||
| 801 | *** Support for multiple todo files and archive files of done items. | ||
| 802 | |||
| 803 | *** Renaming, reordering, moving, merging, and deleting categories. | ||
| 804 | |||
| 805 | *** Sortable tabular summaries of categories and the item types they contain. | ||
| 806 | |||
| 807 | *** Cross-category lists of items filtered by specific criteria. | ||
| 808 | |||
| 809 | *** More fine-grained interaction with the Emacs diary, by being able to | ||
| 810 | decide for each todo item whether it appears in the Fancy Diary display. | ||
| 811 | |||
| 812 | *** Highly flexible new item insertion and item editing. | ||
| 813 | |||
| 814 | *** Moving items between categories, storing done items in their category | ||
| 815 | or in archive files, undoing or unarchiving done items. | ||
| 816 | |||
| 817 | *** Reprioritizing items by inputting a numerical priority. | ||
| 818 | |||
| 819 | *** Extensive customizability of operation and display, including many faces. | ||
| 820 | |||
| 821 | ** Trace | ||
| 822 | |||
| 823 | *** `trace-function' and `trace-function-background' no longer prompt for | ||
| 824 | the output buffer. Unless you use a prefix argument, they output to | ||
| 825 | `trace-buffer'. | ||
| 826 | |||
| 827 | *** With a prefix argument, `trace-function' and `trace-function-background' | ||
| 828 | will prompt for a "context". This is a Lisp expression, whose value at the | ||
| 829 | time the function is entered/exited is printed along with the function's | ||
| 830 | name and arguments. | ||
| 831 | |||
| 832 | ** Tramp | ||
| 833 | |||
| 834 | *** New connection method "adb", which allows to access Android | ||
| 835 | devices by the Android Debug Bridge. The variable `tramp-adb-program' | ||
| 836 | can be used to adapt the path of the "adb" program, if needed. | ||
| 837 | |||
| 838 | *** Handlers for `file-acl' and `set-file-acl' for remote machines | ||
| 839 | that support POSIX ACLs. | ||
| 840 | |||
| 841 | *** Handlers for `file-notify-add-watch' and `file-notify-rm-watch' | ||
| 842 | for remote machines that support filesystem notifications. | ||
| 843 | |||
| 844 | *** The experimental url syntax for remote file names has been removed. | ||
| 845 | |||
| 846 | *** The connection methods "plink1", "ssh1", "ssh2", "scp1", "scp2", | ||
| 847 | "scpc" and "rsyncc" are discontinued. The ssh option | ||
| 848 | "ControlMaster=auto" is set automatically in all ssh-based methods, | ||
| 849 | when possible. See `tramp-use-ssh-controlmaster-options'. | ||
| 850 | |||
| 851 | ** New URL command `url-cookie-list' displays the current cookies, | ||
| 852 | and allows you to interactively remove cookies. | ||
| 853 | |||
| 854 | ** VC and related modes | ||
| 855 | |||
| 856 | *** In VC directory mode, `D' displays diffs between VC-controlled | ||
| 857 | whole tree revisions. | ||
| 858 | |||
| 859 | *** In VC directory mode, `L' lists the change log for the current VC | ||
| 860 | controlled tree in a window. | ||
| 861 | |||
| 862 | *** In VC directory mode, `I' shows a log of changes that will be | ||
| 863 | received with a pull operation. | ||
| 864 | |||
| 865 | *** `C-x v G' (globally) and `G' (in VC directory mode) ignores a file | ||
| 866 | under current version control system. When called with a prefix | ||
| 867 | argument, you can remove a file from the ignored file list. | ||
| 868 | |||
| 869 | ** VHDL mode | ||
| 870 | |||
| 871 | *** New options: `vhdl-actual-generic-name', `vhdl-beautify-options'. | ||
| 872 | |||
| 873 | *** New commands: `vhdl-fix-statement-region', `vhdl-fix-statement-buffer'. | ||
| 874 | |||
| 875 | ** The Woman commands `woman-default-faces' and `woman-monochrome-faces' | ||
| 876 | are obsolete. Customize the `woman-*' faces instead. | ||
| 877 | |||
| 878 | ** More packages look for ~/.emacs.d/<foo> additionally to ~/.<foo>. | ||
| 879 | Affected files: | ||
| 880 | ~/.emacs.d/timelog replaces ~/.timelog | ||
| 881 | ~/.emacs.d/vip replaces ~/.vip | ||
| 882 | ~/.emacs.d/viper replaces ~/.viper | ||
| 883 | ~/.emacs.d/ido.last replaces ~/.ido.last | ||
| 884 | ~/.emacs.d/kkcrc replaces ~/.kkcrc | ||
| 885 | ~/.emacs.d/quickurls replaces ~/.quickurls | ||
| 886 | ~/.emacs.d/idlwave/ replaces ~/.idlwave/ | ||
| 887 | ~/.emacs.d/bdfcache.el replaces ~/.bdfcache.el | ||
| 888 | ~/.emacs.d/places replaces ~/.emacs-places | ||
| 889 | ~/.emacs.d/shadows replaces ~/.shadows | ||
| 890 | ~/.emacs.d/shadow_todo replaces ~/.shadow_todo | ||
| 891 | ~/.emacs.d/strokes replaces ~/.strokes | ||
| 892 | ~/.emacs.d/notes replaces ~/.notes | ||
| 893 | ~/.emacs.d/type-break replaces ~/.type-break | ||
| 894 | Also the following files used by the now obsolete otodo-mode.el: | ||
| 895 | ~/.emacs.d/todo-do replaces ~/.todo-do | ||
| 896 | ~/.emacs.d/todo-done replaces ~/.todo-done | ||
| 897 | ~/.emacs.d/todo-top replaces ~/.todo-top | ||
| 898 | |||
| 899 | ** Obsolete packages | ||
| 900 | |||
| 901 | *** iswitchb.el; use icomplete-mode. | ||
| 902 | |||
| 903 | *** longlines.el; use visual-line-mode. | ||
| 904 | |||
| 905 | *** meese.el. | ||
| 906 | |||
| 907 | *** sup-mouse.el. | ||
| 908 | |||
| 909 | *** terminal.el; use term.el instead. | ||
| 910 | |||
| 911 | *** the old version of todo-mode.el (renamed to otodo-mode.el). | ||
| 912 | |||
| 913 | *** xesam.el (owing to the cancellation of the XESAM project). | ||
| 914 | |||
| 915 | *** yow.el; use fortune.el or cookie1.el instead. | ||
| 916 | |||
| 917 | |||
| 918 | * New Modes and Packages in Emacs 24.4 | ||
| 919 | |||
| 920 | ** New package eww.el provides a built-in web browser. | ||
| 921 | This requires Emacs to have been compiled with libxml2 support. | ||
| 922 | |||
| 923 | ** New package nadvice.el offers lighter-weight advice facilities. | ||
| 924 | It is layered as: | ||
| 925 | |||
| 926 | *** `add-function'/`remove-function', which can be used to add/remove code on | ||
| 927 | any function-carrying place, such as process filters or `<foo>-function' hooks. | ||
| 928 | |||
| 929 | *** `advice-add'/`advice-remove' to add/remove a piece of advice on a named | ||
| 930 | function, much like `defadvice' does. | ||
| 931 | |||
| 932 | ** New package frameset.el provides a set of operations to save a frameset | ||
| 933 | (the state of all or a subset of the existing frames and windows, somewhat | ||
| 934 | similar to a frame configuration), both in-session and persistently, and | ||
| 935 | restore it at some point in the future. | ||
| 936 | |||
| 937 | ** New package filenotify.el provides an interface for file system | ||
| 938 | notifications. It requires that Emacs be compiled with one of the | ||
| 939 | low-level libraries gfilenotify.c, inotify.c or w32notify.c. | ||
| 940 | |||
| 941 | ** New minor modes `prettify-symbols-mode' and `global-prettify-symbols-mode' | ||
| 942 | display specified symbols as composed characters. E.g., in Emacs Lisp mode, | ||
| 943 | this replaces the string "lambda" with the Greek lambda character. | ||
| 944 | |||
| 945 | ** New minor mode `superword-mode', which overrides the default word motion | ||
| 946 | commands to treat "symbol_words" as a single word, similar to what | ||
| 947 | `subword-mode' does. | ||
| 948 | |||
| 949 | |||
| 950 | * Incompatible Lisp Changes in Emacs 24.4 | ||
| 951 | |||
| 952 | ** The default file coding for Emacs Lisp files is now utf-8. | ||
| 953 | (See `file-coding-system-alist'.) In most cases, this change is | ||
| 954 | transparent, but files that contain unusual characters without | ||
| 955 | specifying an explicit coding system may fail to load with obscure | ||
| 956 | errors. You should either convert them to utf-8 or add an explicit | ||
| 957 | `coding:' cookie. | ||
| 958 | |||
| 959 | ** Default process filters and sentinels are not nil any more. | ||
| 960 | Instead they default to a function that does what the nil value used to do. | ||
| 961 | |||
| 962 | ** Overlay priority does not have to be nil or a non-negative integer. | ||
| 963 | Overlay priority can be other kinds of Lisp objects. We didn't yet | ||
| 964 | decide whether other types of values are stable enough, and therefore | ||
| 965 | don't feel it's right to document them. For now, don't assume in your | ||
| 966 | code that the values of overlay priority can only be either nil or an | ||
| 967 | integer, always test them with an appropriate predicate to be one or | ||
| 968 | the other. If you need to sort arbitrary overlays into priority | ||
| 969 | order, `overlays-at' can now optionally do this. | ||
| 970 | You should still only specify integer priorities on overlays you create. | ||
| 971 | |||
| 972 | ** The cars of the elements in `interpreter-mode-alist' are now | ||
| 973 | treated as regexps rather than literal strings. | ||
| 974 | |||
| 975 | ** `overriding-terminal-local-map' no longer replaces the local keymaps. | ||
| 976 | It used to disable the minor mode, major mode, and text-property keymaps, | ||
| 977 | whereas now it simply has higher precedence. | ||
| 978 | |||
| 979 | ** `kill-region' has lost its `yank-handler' optional argument. | ||
| 980 | |||
| 981 | ** `(input-pending-p)' no longer runs other timers that are ready to run. | ||
| 982 | The new optional CHECK-TIMERS parameter allows for the prior behavior. | ||
| 983 | |||
| 984 | ** `defvar' and `defcustom' in a let-binding affect the "external" default. | ||
| 985 | |||
| 986 | ** The syntax of ?» and ?« is now punctuation instead of matched parens. | ||
| 987 | Some languages match those as »...«, and others as «...», so it is | ||
| 988 | better for Emacs to stay neutral by default. | ||
| 989 | |||
| 990 | ** `read-event' does not always decode chars in ttys any more. As was the case | ||
| 991 | in Emacs 22 and before, `read-event' (and `read-char') by default read raw | ||
| 992 | bytes from the terminal. If you want to read decoded chars instead (as was | ||
| 993 | always the case in Emacs-23, for example), pass a non-nil | ||
| 994 | `inherit-input-method' argument. | ||
| 995 | |||
| 996 | ** In `symbol-function', nil and "unbound" are indistinguishable. | ||
| 997 | `symbol-function' does not signal a `void-function' error any more. | ||
| 998 | To determine if a symbol's function definition is void, use `fboundp'. | ||
| 999 | |||
| 1000 | ** `defadvice' does not honor the `freeze' flag and cannot advise | ||
| 1001 | special-forms any more. | ||
| 1002 | |||
| 1003 | ** `dolist' no longer binds VAR while evaluating the RESULT form, | ||
| 1004 | when lexical binding is enabled. Previously, VAR was bound to nil, | ||
| 1005 | which often led to spurious unused-variable warnings. | ||
| 1006 | |||
| 1007 | ** The return value of `backup-buffer' has changed. | ||
| 1008 | The second argument is no longer an SELinux context, instead it is an | ||
| 1009 | alist of extended attributes as returned by the new function | ||
| 1010 | `file-extended-attributes'. The attributes can be applied to another | ||
| 1011 | file using `set-file-extended-attributes'. | ||
| 1012 | |||
| 1013 | ** By default `copy-file' no longer copies file permission bits to an | ||
| 1014 | existing destination; and it sets the file permission bits of a newly | ||
| 1015 | created destination to those of the source, masked by the default file | ||
| 1016 | permissions. To copy the file permission bits, pass t as the | ||
| 1017 | PRESERVE-PERMISSIONS argument of `copy-file'. | ||
| 1018 | |||
| 1019 | ** `visited-file-modtime' now returns -1 for nonexistent files. | ||
| 1020 | Formerly it returned a list (-1 LOW USEC PSEC), but this was ambiguous | ||
| 1021 | in the presence of files with negative time stamps. | ||
| 1022 | |||
| 1023 | ** Frame-local variables that affect redisplay do not work any more. | ||
| 1024 | More specifically, redisplay does not bother to check for a frame-local | ||
| 1025 | value when looking up variables. | ||
| 1026 | |||
| 1027 | ** In compiled Lisp files, the header no longer includes a timestamp. | ||
| 1028 | |||
| 1029 | ** The option `inhibit-local-menu-bar-menus' has been removed. | ||
| 1030 | |||
| 1031 | |||
| 1032 | * Lisp Changes in Emacs 24.4 | ||
| 1033 | |||
| 1034 | ** Change to the Emacs Lisp coding conventions: the package descriptor | ||
| 1035 | and name of global variables, constants, and functions should be separated | ||
| 1036 | by two hyphens if the symbol is not meant to be used by other packages. | ||
| 1037 | |||
| 1038 | ** The second argument of `eval' can now specify a lexical environment. | ||
| 1039 | |||
| 1040 | ** New macro `define-alternatives' can be used to define generic commands. | ||
| 1041 | Generic commands are interactive functions whose implementation can be | ||
| 1042 | selected among several alternatives, as a matter of user preference. | ||
| 1043 | |||
| 1044 | ** Numeric comparison functions =, <, >, <=, >= can now take many arguments. | ||
| 1045 | |||
| 1046 | ** New functions `special-form-p' and `macrop'. | ||
| 1047 | |||
| 1048 | ** New macro `with-eval-after-load'. | ||
| 1049 | This is like the old `eval-after-load', but better behaved. | ||
| 1050 | |||
| 1051 | ** If you give a symbol a `defalias-fset-function' property, `defalias' | ||
| 1052 | on that symbol will use the associated value as a function to call | ||
| 1053 | in place of `fset'. | ||
| 1054 | |||
| 1055 | ** New variable `enable-dir-local-variables'. | ||
| 1056 | Directory-local variables are ignored if this is nil. This may be | ||
| 1057 | useful for modes that want to ignore directory-locals while still | ||
| 1058 | respecting file-local variables. | ||
| 1059 | |||
| 1060 | ** `read-regexp' now uses the new variable `read-regexp-defaults-function' | ||
| 1061 | as a function to call to provide default values. | ||
| 1062 | |||
| 1063 | ** New functions `group-gid' and `group-real-gid'. | ||
| 1064 | |||
| 1065 | ** New function `get-pos-property'. | ||
| 1066 | |||
| 1067 | ** New hook `pre-redisplay-function'. | ||
| 1068 | |||
| 1069 | ** `byte-compile-interactive-only-functions' is now obsolete. | ||
| 1070 | To specify that a command should only be called interactively, give it | ||
| 1071 | a non-nil `interactive-only' property. | ||
| 1072 | |||
| 1073 | ** New function `string-suffix-p'. | ||
| 1074 | |||
| 1075 | ** `split-string' now takes an optional argument TRIM. | ||
| 1076 | The value, if non-nil, is a regexp that specifies what to trim from | ||
| 1077 | the start and end of each substring. | ||
| 1078 | |||
| 1079 | ** Completion | ||
| 1080 | |||
| 1081 | *** The separator used by `completing-read-multiple' is now a regexp. | ||
| 1082 | The default `crm-separator' has been changed to allow surrounding spaces | ||
| 1083 | around the comma. | ||
| 1084 | |||
| 1085 | *** New function `completion-table-with-cache' is a wrapper for | ||
| 1086 | `completion-table-dynamic' that caches the result of the last lookup. | ||
| 1087 | |||
| 1088 | *** New function `completion-table-merge' to combine several | ||
| 1089 | completion tables by merging their completions. | ||
| 1090 | |||
| 1091 | *** The `common-substring' argument of `display-completion-list', | ||
| 1092 | which has been documented as obsolete since Emacs 23.1, is now _really_ | ||
| 1093 | obsolete, and no longer advertised. Instead either call | ||
| 1094 | `completion-hilit-commonality' to add the highlighting; or use | ||
| 1095 | `completion-all-completions', which returns highlighted strings. | ||
| 1096 | |||
| 1097 | ** Encoding and decoding of text | ||
| 1098 | |||
| 1099 | *** New coding-system `prefer-utf-8'. | ||
| 1100 | This is like `undecided' but prefers UTF-8 on decoding if the text to | ||
| 1101 | be decoded does not contain any invalid UTF-8 sequences. On encoding, | ||
| 1102 | any non-ASCII characters are automatically encoded as UTF-8. | ||
| 1103 | |||
| 1104 | *** New attributes of coding-systems whose type is `undecided'. | ||
| 1105 | Two new attributes, `:inhibit-null-byte-detection' and | ||
| 1106 | `:inhibit-iso-escape-detection', determine how to detect encoding of | ||
| 1107 | text that includes null bytes and ISO-2022 escape sequences, respectively. | ||
| 1108 | Each of these attributes can be either nil, zero, or t. If t, decoding | ||
| 1109 | text ignores null bytes and ISO-2022 sequences, respectively. If nil, | ||
| 1110 | null bytes cause text to be decoded with no-conversion, and ISO-2022 | ||
| 1111 | sequences cause Emacs to assume the text is encoded in one of the ISO-2022 | ||
| 1112 | encodings, such as iso-2022-7bit. If zero, Emacs consults the variables | ||
| 1113 | `inhibit-null-byte-detection' and `inhibit-iso-escape-detection'. | ||
| 1114 | The new attribute `:prefer-utf-8', if non-nil, causes Emacs to prefer | ||
| 1115 | UTF-8 encoding and decoding, whenever possible. | ||
| 1116 | |||
| 1117 | These attributes are only meaningful for coding-systems of type `undecided'. | ||
| 1118 | (The type of a coding-system is determined by its `:coding-type' attribute | ||
| 1119 | and can be accessed by calling the `coding-system-type' function.) | ||
| 1120 | |||
| 1121 | ** Error-handling | ||
| 1122 | |||
| 1123 | *** New function `define-error'. | ||
| 1124 | |||
| 1125 | *** `with-demoted-errors' takes an additional argument `format'. | ||
| 1126 | |||
| 1127 | *** Errors from timer functions are no longer silently discarded, | ||
| 1128 | but are reported as messages. So you may see "Error running timer" | ||
| 1129 | messages from code that was failing silently till now. Set | ||
| 1130 | `debug-on-error' non-nil to get a real error and a backtrace. | ||
| 1131 | |||
| 1132 | ** Faces | ||
| 1133 | |||
| 1134 | *** Face specs set via Custom themes now replace the `defface' spec | ||
| 1135 | rather than inheriting from it. In other words, setting a face via a | ||
| 1136 | theme now behaves like setting it via Customize: you only need to | ||
| 1137 | specify the attributes that you want, you don't need to unset those | ||
| 1138 | that you don't want. | ||
| 1139 | |||
| 1140 | *** The function `face-spec-set' is now like `setq' for face specs. | ||
| 1141 | Its third arg now accepts values specifying a face spec type (defface, | ||
| 1142 | custom, or override spec), and the relevant spec is set accordingly. | ||
| 1143 | |||
| 1144 | *** New face spec attribute :distant-foreground | ||
| 1145 | specifies foreground to use if background color is near the foreground | ||
| 1146 | color that would otherwise have been used. | ||
| 1147 | |||
| 1148 | *** New function `add-face-text-property', which can be used to | ||
| 1149 | conveniently prepend/append new face properties. | ||
| 1150 | |||
| 1151 | *** New face characteristic (supports :underline (:style wave)) | ||
| 1152 | specifies whether or not the terminal can display a wavy line. | ||
| 1153 | |||
| 1154 | ** File-handling | ||
| 1155 | |||
| 1156 | *** Support for filesystem notifications. | ||
| 1157 | Emacs now supports notifications of filesystem changes, such as | ||
| 1158 | creation, modification, and deletion of files. This requires the | ||
| 1159 | `glib' API, or the 'inotify' API (on GNU/Linux systems only). On | ||
| 1160 | MS-Windows systems, this is supported for Windows XP and newer. | ||
| 1161 | |||
| 1162 | *** The 9th element returned by `file-attributes' is now unspecified. | ||
| 1163 | Formerly, it was t if the file's gid would change if file were deleted | ||
| 1164 | and recreated. This value has been inaccurate for years on many | ||
| 1165 | platforms, and nobody seems to have noticed or cared. | ||
| 1166 | |||
| 1167 | *** The 6th argument to `copy-file' has been renamed to | ||
| 1168 | PRESERVE-PERMISSIONS as it now handles ACL entries and the traditional | ||
| 1169 | Unix file permission bits as well as SELinux context. | ||
| 1170 | |||
| 1171 | *** The function `file-ownership-preserved-p' now has an optional | ||
| 1172 | argument GROUP which causes it check for file group too. This can be | ||
| 1173 | used in place of the 9th element of `file-attributes'. | ||
| 1174 | |||
| 1175 | *** The function `set-visited-file-modtime' now accepts a 0 or -1 argument, | ||
| 1176 | with the same interpretation as the returned value of `visited-file-modtime'. | ||
| 1177 | |||
| 1178 | ** Image API | ||
| 1179 | |||
| 1180 | *** `image-animated-p' is now `image-multi-frame-p'. | ||
| 1181 | It returns non-nil for any image that contains multiple frames, | ||
| 1182 | whether or not it specifies a frame delay. | ||
| 1183 | |||
| 1184 | *** New variable `image-default-frame-delay' gives the frame delay for | ||
| 1185 | animated images which do not specify a frame delay. | ||
| 1186 | |||
| 1187 | *** New functions `image-current-frame' and `image-show-frame' for getting | ||
| 1188 | and setting the current frame of a multi-frame image. | ||
| 1189 | |||
| 1190 | ** ImageMagick | ||
| 1191 | |||
| 1192 | *** ImageMagick images now support the :max-width and :max-height keywords. | ||
| 1193 | |||
| 1194 | *** When using `create-image' with image data, you can pass a :format | ||
| 1195 | attribute (via the property-list argument) in order to help | ||
| 1196 | ImageMagick detect the image type. The value should be a MIME | ||
| 1197 | content-type that is found in the new variable `image-format-suffixes'. | ||
| 1198 | |||
| 1199 | ** Revert and Autorevert | ||
| 1200 | |||
| 1201 | *** If Emacs is compiled with file notification support, it uses notifications | ||
| 1202 | instead of checking file time stamps. To disable this, set the user option | ||
| 1203 | `auto-revert-use-notify' to nil. Alternatively, you can specify a regular | ||
| 1204 | expression matching directories to be excluded from file notifications via | ||
| 1205 | `auto-revert-notify-exclude-dir-regexp'. | ||
| 1206 | |||
| 1207 | *** The default values of `buffer-stale-function', `revert-buffer-function', | ||
| 1208 | and `revert-buffer-insert-file-contents-function' are no longer nil. | ||
| 1209 | Instead they default to functions that do what the nil value used to. | ||
| 1210 | |||
| 1211 | *** `buffer-stale-function' is now used for buffers visiting files too. | ||
| 1212 | |||
| 1213 | *** The new user option `auto-revert-remote-files' enables reversion | ||
| 1214 | of remote files, if non-nil. | ||
| 1215 | |||
| 1216 | ** Terminal | ||
| 1217 | |||
| 1218 | *** Functions to pop up menus and dialogs now work on all terminals, | ||
| 1219 | including TTYs. This includes `x-popup-menu', `x-popup-dialog', | ||
| 1220 | `message-box', `yes-or-no-p', etc. | ||
| 1221 | |||
| 1222 | The function `display-popup-menus-p' will now return non-nil for a | ||
| 1223 | display or frame whenever a mouse is supported on that display or frame. | ||
| 1224 | |||
| 1225 | *** New hook `tty-setup-hook', run at the end of initializing a text terminal. | ||
| 1226 | |||
| 1227 | *** The hook `term-setup-hook' is obsolete. It is entirely equivalent | ||
| 1228 | to `emacs-startup-hook'. See also the new `tty-setup-hook'. | ||
| 1229 | |||
| 1230 | ** Minor internal changes to the details of lock files. | ||
| 1231 | The lock for DIR/FILE is now _always_ DIR/.#FILE. | ||
| 1232 | If DIR/.#FILE already exists and is not an Emacs lock file, | ||
| 1233 | Emacs makes no attempt to lock DIR/FILE. (Previously, it fell back to | ||
| 1234 | numbered lock files DIR/.#FILE.0...). | ||
| 1235 | On file systems that do not support symbolic links, the lock is now a | ||
| 1236 | regular file with contents being what would have been in the symlink. | ||
| 1237 | |||
| 1238 | ** New bool-vector set operation functions: | ||
| 1239 | *** `bool-vector-exclusive-or' | ||
| 1240 | *** `bool-vector-union' | ||
| 1241 | *** `bool-vector-intersection' | ||
| 1242 | *** `bool-vector-set-difference' | ||
| 1243 | *** `bool-vector-not' | ||
| 1244 | *** `bool-vector-subsetp' | ||
| 1245 | *** `bool-vector-count-consecutive' | ||
| 1246 | *** `bool-vector-count-population' | ||
| 1247 | |||
| 1248 | ** New library subr-x.el with miscellaneous small utility functions: | ||
| 1249 | *** `hash-table-keys' | ||
| 1250 | *** `hash-table-values' | ||
| 1251 | *** `string-blank-p' | ||
| 1252 | *** `string-empty-p' | ||
| 1253 | *** `string-join' | ||
| 1254 | *** `string-reverse' | ||
| 1255 | *** `string-trim-left' | ||
| 1256 | *** `string-trim-right' | ||
| 1257 | *** `string-trim' | ||
| 1258 | *** `string-remove-prefix' | ||
| 1259 | *** `string-remove-suffix' | ||
| 1260 | |||
| 1261 | ** The `time-to-seconds' alias to `float-time' is no longer marked obsolete. | ||
| 1262 | |||
| 1263 | ** The spelling of the rx.el category `chinese-two-byte' has been | ||
| 1264 | corrected (the first 'e' was missing). | ||
| 1265 | |||
| 1266 | ** EIEIO namespace cleanup, obsolete-aliasing functions to use `eieio-' prefix: | ||
| 1267 | *** object-name -> eieio-object-name | ||
| 1268 | *** object-class -> eieio-object-class | ||
| 1269 | *** object-class-fast -> eieio--object-class | ||
| 1270 | *** object-class-name -> eieio-object-class-name | ||
| 1271 | *** object-name-string -> eieio-object-name-string | ||
| 1272 | *** object-num-slots -> eieio--object-num-slots | ||
| 1273 | *** object-set-name-string -> eieio-object-set-name-string | ||
| 1274 | *** class-of -> eieio-object-class | ||
| 1275 | *** class-name -> eieio-class-name | ||
| 1276 | *** class-parent -> eieio-class-parent | ||
| 1277 | *** class-parents -> eieio-class-parents | ||
| 1278 | *** class-parents-fast -> eieio-class-parents-fast | ||
| 1279 | *** class-children -> eieio-class-children | ||
| 1280 | *** class-num-slots -> eieio--class-num-slots | ||
| 1281 | *** class-precedence-list -> eieio-class-precedence-list | ||
| 1282 | *** class-direct-subclasses -> eieio-class-children | ||
| 1283 | *** class-direct-superclasses -> eieio-class-parents | ||
| 1284 | |||
| 1285 | ** Obsoleted functions | ||
| 1286 | *** `log10' | ||
| 1287 | *** `dont-compile' | ||
| 1288 | *** `lisp-complete-symbol' | ||
| 1289 | *** `field-complete' | ||
| 1290 | *** `minibuffer-completion-contents' | ||
| 1291 | *** `isearch-nonincremental-exit-minibuffer' | ||
| 1292 | *** `isearch-filter-visible' | ||
| 1293 | *** `generic-make-keywords-list' | ||
| 1294 | *** `get-upcase-table' (use `case-table-get-table' instead). | ||
| 1295 | |||
| 1296 | ** `with-wrapper-hook' is obsoleted by `add-function'. | ||
| 1297 | The few hooks that used with-wrapper-hook are replaced as follows: | ||
| 1298 | *** `abbrev-expand-function' obsoletes `abbrev-expand-functions'. | ||
| 1299 | *** `completion-in-region-function' obsoletes `completion-in-region-functions'. | ||
| 1300 | *** `filter-buffer-substring-function' obsoletes `filter-buffer-substring-functions'. | ||
| 1301 | |||
| 1302 | |||
| 1303 | * Changes in Emacs 24.4 on Non-Free Operating Systems | ||
| 1304 | |||
| 1305 | ** New Core Text based font backend for Mac OS X 10.5 and newer. | ||
| 1306 | To use the old font backend, use the following on the command line: | ||
| 1307 | % defaults write org.gnu.Emacs FontBackend ns | ||
| 1308 | GNUstep and Mac OS X 10.4 use the old font backend. | ||
| 1309 | |||
| 1310 | ** Improved fullscreen support on Mac OS X 10.7 and newer, where the | ||
| 1311 | default fullscreen method is now "native" fullscreen. To use the | ||
| 1312 | old style fullscreen, customize `ns-use-native-fullscreen' to nil. | ||
| 1313 | |||
| 1314 | ** On Mac OS X 10.7 and newer, Emacs can use sRGB colorspace, and does so | ||
| 1315 | by default. Customize `ns-use-srgb-colorspace' to go back to the old method. | ||
| 1316 | Note that this does not apply to images. | ||
| 1317 | |||
| 1318 | ** The procedure for building Emacs on MS-Windows has changed. | ||
| 1319 | It is now built by running the same configure script as on all other | ||
| 1320 | platforms. This requires the MSYS environment and MinGW development | ||
| 1321 | tools. See the updated instructions in nt/INSTALL for details. | ||
| 1322 | |||
| 1323 | Using the Posix configure script and Makefiles also means a change in | ||
| 1324 | the directory structure of the Emacs installation on Windows. It is | ||
| 1325 | now the same as on GNU and Unix systems. In particular, the auxiliary | ||
| 1326 | programs, such as cmdproxy.exe and hexl.exe, are in | ||
| 1327 | libexec/emacs/VERSION/i686-pc-mingw32 (where VERSION is the Emacs | ||
| 1328 | version), version-independent site-lisp is in share/emacs/site-lisp, | ||
| 1329 | version-specific Lisp files are in share/emacs/VERSION/lisp and in | ||
| 1330 | share/emacs/VERSION/site-lisp, Info docs are in share/info, and data | ||
| 1331 | files are in share/emacs/VERSION/etc. (Emacs knows about all these | ||
| 1332 | directories and will find the files in there automatically; there's no | ||
| 1333 | need to set any variables due to this change.) | ||
| 1334 | |||
| 1335 | ** Emacs on Windows 2000 and later can now access files and directories | ||
| 1336 | whose names cannot be encoded in the current system codepage. | ||
| 1337 | |||
| 1338 | The new variable `w32-unicode-filenames' controls this feature: if it | ||
| 1339 | is t, Emacs uses Unicode APIs to pass file names to system calls, | ||
| 1340 | which lifts the limitation of file names to the current locale. | ||
| 1341 | |||
| 1342 | ** Lock files now work on MS-Windows. | ||
| 1343 | This helps to prevent losing your edits if the same file is being | ||
| 1344 | edited in another Emacs session or by another user. See the node | ||
| 1345 | "Interlocking" in the Emacs User Manual for the details. To disable | ||
| 1346 | file locking, customize `create-lockfiles' to nil. | ||
| 1347 | |||
| 1348 | ** The "generate a backtrace on fatal error" feature now works on MS-Windows. | ||
| 1349 | The backtrace is written to the 'emacs_backtrace.txt' file in the | ||
| 1350 | directory where Emacs was running. | ||
| 1351 | |||
| 1352 | ** The `network-interface-list' and `network-interface-info' functions | ||
| 1353 | are now available on MS-Windows. | ||
| 1354 | |||
| 1355 | ** The variable `buffer-file-type' is no longer supported. | ||
| 1356 | Setting it has no effect, and %t in the mode-line format is ignored. | ||
| 1357 | Likewise, `file-name-buffer-file-type-alist' is now obsolete, and | ||
| 1358 | modifying it has no effect. | ||
| 1359 | |||
| 1360 | |||
| 1361 | * Installation Changes in Emacs 24.3 | ||
| 1362 | |||
| 1363 | ** The default X toolkit is now Gtk+ version 3. | ||
| 1364 | If you don't pass `--with-x-toolkit' to configure, or if you use | ||
| 1365 | `--with-x-toolkit=gtk' or `--with-x-toolkit=yes', configure will try | ||
| 1366 | to build with Gtk+ version 3, and if that fails, try Gtk+ version 2. | ||
| 1367 | You can explicitly require a specific version by passing | ||
| 1368 | `--with-x-toolkit=gtk2' or `--with-x-toolkit=gtk3' to configure. | ||
| 1369 | |||
| 1370 | ** New configure option `--enable-link-time-optimization', to utilize | ||
| 1371 | an appropriate feature provided by GCC since version 4.5.0. | ||
| 1372 | |||
| 1373 | ** New configure option `--without-all' to disable most of the optional | ||
| 1374 | features (image support, etc.) that are normally enabled by default. | ||
| 1375 | |||
| 1376 | ** New configure option `--enable-gcc-warnings' (for developing/debugging | ||
| 1377 | Emacs). If building with GCC, this enables compile-time checks that | ||
| 1378 | warn/give errors about possibly-questionable C code. On a recent GNU | ||
| 1379 | system there should be no warnings; on older and on non-GNU systems | ||
| 1380 | the results may be useful to developers. | ||
| 1381 | |||
| 1382 | ** The configure option `--enable-use-lisp-union-type' has been | ||
| 1383 | renamed to `--enable-check-lisp-object-type', as the resulting | ||
| 1384 | Lisp_Object type no longer uses a union to implement the compile time | ||
| 1385 | check that this option enables. | ||
| 1386 | |||
| 1387 | ** The configure option `--disable-maintainer-mode' has been removed, | ||
| 1388 | as it was confusingly-named and rarely useful. | ||
| 1389 | |||
| 1390 | ** The configure options `--program-prefix', `--program-suffix', and | ||
| 1391 | `--program-transform-name' apply to more than just the installed | ||
| 1392 | binaries. Now they also affect the man pages, icons, and the | ||
| 1393 | etc/emacs.desktop file; but not the info pages, since this would break | ||
| 1394 | links between the various manuals. | ||
| 1395 | |||
| 1396 | ** You can use `NO_BIN_LINK=t make install' to prevent the installation | ||
| 1397 | overwriting "emacs" in the installation bin/ directory with a link | ||
| 1398 | to "emacs-VERSION". | ||
| 1399 | |||
| 1400 | ** Emacs uses libtinfo in preference to libncurses, if available. | ||
| 1401 | |||
| 1402 | ** On FreeBSD and NetBSD, configure no longer adds /usr/local/lib and | ||
| 1403 | /usr/pkg/lib to the linker search path. You must add them yourself if | ||
| 1404 | you want them. | ||
| 1405 | |||
| 1406 | ** The standalone scripts `rcs-checkin' and `vcdiff' have been removed | ||
| 1407 | (from the bin and libexec directories, respectively). The former is | ||
| 1408 | no longer relevant, the latter is replaced by lisp (in vc-sccs.el). | ||
| 1409 | |||
| 1410 | |||
| 1411 | * Startup Changes in Emacs 24.3 | ||
| 1412 | |||
| 1413 | ** Emacs no longer searches for `leim-list.el' files beneath the standard | ||
| 1414 | lisp/ directory. There should not be any there anyway. If you have | ||
| 1415 | been adding them there, put them somewhere else; e.g., site-lisp. | ||
| 1416 | |||
| 1417 | ** The `--no-site-lisp' command line option now works for Nextstep builds. | ||
| 1418 | |||
| 1419 | |||
| 1420 | * Changes in Emacs 24.3 | ||
| 1421 | |||
| 1422 | ** Help | ||
| 1423 | |||
| 1424 | *** `C-h f' (`describe-function') can now perform autoloading. | ||
| 1425 | When this command is called for an autoloaded function whose docstring | ||
| 1426 | contains a key substitution construct, that function's library is | ||
| 1427 | automatically loaded, so that the documentation can be shown | ||
| 1428 | correctly. To disable this, set `help-enable-auto-load' to nil. | ||
| 1429 | |||
| 1430 | *** `C-h f' now reports previously-autoloaded functions as "autoloaded", | ||
| 1431 | even after their associated libraries have been loaded (and the | ||
| 1432 | autoloads have been redefined as functions). | ||
| 1433 | |||
| 1434 | ** ImageMagick | ||
| 1435 | |||
| 1436 | *** Images displayed via ImageMagick now support transparency and the | ||
| 1437 | :background image specification property. | ||
| 1438 | |||
| 1439 | *** When available, ImageMagick support is automatically enabled. | ||
| 1440 | It is no longer necessary to call `imagemagick-register-types' | ||
| 1441 | explicitly to install ImageMagick image types; that function is called | ||
| 1442 | automatically at startup, or when customizing an imagemagick- option. | ||
| 1443 | |||
| 1444 | *** Setting `imagemagick-types-inhibit' to t now disables the use of | ||
| 1445 | ImageMagick to view images. (You must call `imagemagick-register-types' | ||
| 1446 | afterwards if you do not use customize to change this.) | ||
| 1447 | |||
| 1448 | *** The new variable `imagemagick-enabled-types' also affects which | ||
| 1449 | ImageMagick types are treated as images. The function | ||
| 1450 | `imagemagick-filter-types' returns the list of types that will be | ||
| 1451 | treated as images. | ||
| 1452 | |||
| 1453 | ** Minibuffer | ||
| 1454 | |||
| 1455 | *** In minibuffer filename prompts, `C-M-f' and `C-M-b' now move to the | ||
| 1456 | next and previous path separator, respectively. | ||
| 1457 | |||
| 1458 | *** `minibuffer-electric-default-mode' can shorten "(default ...)" to "[...]" | ||
| 1459 | in minibuffer prompts. Just set `minibuffer-eldef-shorten-default' | ||
| 1460 | non-nil before enabling the mode. | ||
| 1461 | |||
| 1462 | ** Mode line | ||
| 1463 | |||
| 1464 | *** New option `mode-line-default-help-echo' specifies the help text | ||
| 1465 | (shown in a tooltip or in the echo area) for any part of the mode line | ||
| 1466 | that does not have its own specialized help text. | ||
| 1467 | |||
| 1468 | *** You can now click mouse-3 in the coding system indicator to invoke | ||
| 1469 | `set-buffer-file-coding-system'. | ||
| 1470 | |||
| 1471 | ** Server and client | ||
| 1472 | |||
| 1473 | *** emacsclient now obeys string values for `initial-buffer-choice', | ||
| 1474 | if it is told to open a new frame without specifying any file to visit | ||
| 1475 | or expression to evaluate. | ||
| 1476 | |||
| 1477 | *** New option `server-auth-key' specifies a shared server key. | ||
| 1478 | |||
| 1479 | ** Emacs now generates backtraces on fatal errors. | ||
| 1480 | On encountering a fatal error, Emacs now outputs a textual description | ||
| 1481 | of the fatal signal, and a short backtrace on platforms like glibc | ||
| 1482 | that support backtraces. | ||
| 1483 | |||
| 1484 | ** `C-x C-q' is now bound to the new minor mode `read-only-mode'. | ||
| 1485 | This minor mode replaces `toggle-read-only', which is now obsolete. | ||
| 1486 | |||
| 1487 | ** Most `y-or-n' prompts now allow you to scroll the selected window. | ||
| 1488 | Typing `C-v' or `M-v' at a y-or-n prompt scrolls forward or backward | ||
| 1489 | respectively, without exiting from the prompt. | ||
| 1490 | |||
| 1491 | ** In the Package Menu, newly-available packages are listed as "new", | ||
| 1492 | and sorted above the other "available" packages by default. | ||
| 1493 | |||
| 1494 | ** If your Emacs was built from a repository checkout, the new variable | ||
| 1495 | `emacs-bzr-version' contains information about the bzr revision used. | ||
| 1496 | |||
| 1497 | ** New option `create-lockfiles' specifies usage of lockfiles. | ||
| 1498 | It defaults to t. Changing it to nil inhibits the creation of lock | ||
| 1499 | files (use this with caution). | ||
| 1500 | |||
| 1501 | ** New option `enable-remote-dir-locals', if non-nil, allows directory-local | ||
| 1502 | variables on remote hosts. | ||
| 1503 | |||
| 1504 | ** The entry for PCL-CVS has been removed from the Tools menu. | ||
| 1505 | The PCL-CVS commands are still available via the keyboard. | ||
| 1506 | |||
| 1507 | ** Using "unibyte: t" in Lisp source files is obsolete. | ||
| 1508 | Use "coding: raw-text" instead. | ||
| 1509 | |||
| 1510 | ** In the buffer made by `M-x report-emacs-bug', the `C-c m' binding | ||
| 1511 | has been changed to `C-c M-i' (`report-emacs-bug-insert-to-mailer'). | ||
| 1512 | The previous binding, introduced in Emacs 24.1, was a mistake, because | ||
| 1513 | `C-c LETTER' bindings are reserved for user customizations. | ||
| 1514 | |||
| 1515 | ** Internationalization | ||
| 1516 | |||
| 1517 | *** New language environment: Persian. | ||
| 1518 | |||
| 1519 | *** New input method `vietnamese-vni'. | ||
| 1520 | |||
| 1521 | ** Nextstep (GNUstep / Mac OS X) port | ||
| 1522 | |||
| 1523 | *** Support for fullscreen and the frame parameter fullscreen. | ||
| 1524 | |||
| 1525 | *** A file dialog is used for open/save operations initiated from the | ||
| 1526 | menu/toolbar. | ||
| 1527 | |||
| 1528 | |||
| 1529 | * Editing Changes in Emacs 24.3 | ||
| 1530 | |||
| 1531 | ** Search and Replace | ||
| 1532 | |||
| 1533 | *** Non-regexp Isearch now performs "lax" space matching. | ||
| 1534 | Each sequence of spaces in the supplied search string may match any | ||
| 1535 | sequence of one or more whitespace characters, as specified by the | ||
| 1536 | variable `search-whitespace-regexp'. (This variable is also used by a | ||
| 1537 | similar existing feature for regexp Isearch.) | ||
| 1538 | |||
| 1539 | *** New Isearch command `M-s SPC' toggles lax space matching. | ||
| 1540 | This applies to both ordinary and regexp Isearch. | ||
| 1541 | |||
| 1542 | *** New option `replace-lax-whitespace'. | ||
| 1543 | If non-nil, `query-replace' uses flexible whitespace matching too. | ||
| 1544 | The default is nil. | ||
| 1545 | |||
| 1546 | *** Global `M-s _' starts a symbol (identifier) incremental search, | ||
| 1547 | and `M-s _' in Isearch toggles symbol search mode. | ||
| 1548 | `M-s c' in Isearch toggles search case-sensitivity. | ||
| 1549 | |||
| 1550 | ** Navigation commands | ||
| 1551 | |||
| 1552 | *** New binding `M-g c' for `goto-char'. | ||
| 1553 | |||
| 1554 | *** New binding `M-g TAB' for `move-to-column'. | ||
| 1555 | |||
| 1556 | *** `M-g TAB' (`move-to-column') prompts for a column number if called | ||
| 1557 | interactively with no prefix arg. Previously, it moved to column 1. | ||
| 1558 | |||
| 1559 | ** New option `yank-handled-properties' allows processing of text | ||
| 1560 | properties on yanked text, in ways that are more general than just | ||
| 1561 | removing them (as is done by `yank-excluded-properties'). | ||
| 1562 | |||
| 1563 | ** New option `delete-trailing-lines' specifies whether | ||
| 1564 | M-x delete-trailing-whitespace should delete trailing lines at the end | ||
| 1565 | of the buffer. It defaults to t. | ||
| 1566 | |||
| 1567 | ** `C-u M-=' now counts lines/words/characters in the entire buffer. | ||
| 1568 | |||
| 1569 | ** `C-x 8 RET' is now bound to `insert-char', which is now a command. | ||
| 1570 | `ucs-insert' is now an obsolete alias for `insert-char'. | ||
| 1571 | |||
| 1572 | ** The `z' key no longer has a binding in most special modes. | ||
| 1573 | It used to be bound to `kill-this-buffer', but `z' is too easy to | ||
| 1574 | accidentally type. | ||
| 1575 | |||
| 1576 | ** New command `C-x r M-w' (`copy-rectangle-as-kill'). | ||
| 1577 | It copies the region-rectangle as the last rectangle kill. | ||
| 1578 | |||
| 1579 | ** Registers | ||
| 1580 | |||
| 1581 | *** `C-x r +' is now overloaded to invoke `append-to-register'. | ||
| 1582 | |||
| 1583 | *** New option `register-separator' specifies the register containing | ||
| 1584 | the text to put between collected texts for use with | ||
| 1585 | M-x append-to-register and M-x prepend-to-register. | ||
| 1586 | |||
| 1587 | |||
| 1588 | * Changes in Specialized Modes and Packages in Emacs 24.3 | ||
| 1589 | |||
| 1590 | ** Common Lisp emulation (CL) | ||
| 1591 | |||
| 1592 | *** CL's main entry is now (require 'cl-lib). | ||
| 1593 | `cl-lib' is like the old `cl' except that it uses the namespace cleanly; | ||
| 1594 | i.e., all its definitions have the "cl-" prefix (and internal definitions | ||
| 1595 | use the "cl--" prefix). | ||
| 1596 | |||
| 1597 | If `cl' provided a feature under the name `foo', then `cl-lib' | ||
| 1598 | provides it under the name `cl-foo' instead; with the exceptions of the | ||
| 1599 | few `cl' definitions that had to use `foo*' to avoid conflicts with | ||
| 1600 | pre-existing Elisp entities. These have been renamed to `cl-foo' | ||
| 1601 | rather than `cl-foo*'. | ||
| 1602 | |||
| 1603 | The old `cl' is now deprecated and is mainly just a bunch of aliases that | ||
| 1604 | provide the old, non-prefixed names. Some exceptions are listed below: | ||
| 1605 | |||
| 1606 | *** `cl-flet' is not like `flet' (which is deprecated). | ||
| 1607 | Instead it obeys the behavior of Common-Lisp's `flet'. | ||
| 1608 | In particular, in cl-flet function definitions are lexically scoped, | ||
| 1609 | whereas in flet the scoping is dynamic. | ||
| 1610 | |||
| 1611 | *** `cl-labels' is slightly different from `labels'. | ||
| 1612 | The difference is that it relies on the `lexical-binding' machinery | ||
| 1613 | (as opposed to the `lexical-let' machinery used previously) to capture | ||
| 1614 | definitions in closures, so such closures will only work if `lexical-binding' | ||
| 1615 | is in use. | ||
| 1616 | |||
| 1617 | *** `cl-letf' is not exactly like `letf'. | ||
| 1618 | The only difference is in details that relate to some deprecated usage | ||
| 1619 | of `symbol-function' in place forms. | ||
| 1620 | |||
| 1621 | *** `progv' was rewritten to use the `let' machinery. | ||
| 1622 | A side effect is that variables without corresponding values are bound | ||
| 1623 | to nil rather than being made unbound. | ||
| 1624 | |||
| 1625 | *** The following methods of extending `setf' are obsolete | ||
| 1626 | (use features from gv.el instead): | ||
| 1627 | `define-modify-macro' (use `gv-letplace') | ||
| 1628 | `defsetf' (use `gv-define-simple-setter' or `gv-define-setter') | ||
| 1629 | `define-setf-expander' (use `gv-define-setter' or `gv-define-expander') | ||
| 1630 | `get-setf-method' no longer exists (see "Incompatible Lisp Changes") | ||
| 1631 | |||
| 1632 | ** Diff mode | ||
| 1633 | |||
| 1634 | *** Changes are now highlighted using the same color scheme as in | ||
| 1635 | modern VCSes. Deletions are displayed in red (new faces | ||
| 1636 | `diff-refine-removed' and `smerge-refined-removed', and new definition | ||
| 1637 | of `diff-removed'), insertions in green (new faces `diff-refine-added' | ||
| 1638 | and `smerge-refined-added', and new definition of `diff-added'). | ||
| 1639 | |||
| 1640 | *** The variable `diff-use-changed-face' defines whether to use the | ||
| 1641 | face `diff-changed', or `diff-removed' and `diff-added' to highlight | ||
| 1642 | changes in context diffs. | ||
| 1643 | |||
| 1644 | *** The new command `diff-delete-trailing-whitespace' removes trailing | ||
| 1645 | whitespace introduced by a diff. | ||
| 1646 | |||
| 1647 | ** Ediff now uses the same color scheme as Diff mode. | ||
| 1648 | |||
| 1649 | ** Python mode | ||
| 1650 | |||
| 1651 | A new version of python.el, which provides several new features, including: | ||
| 1652 | per-buffer shells, better indentation, Python 3 support, and improved | ||
| 1653 | shell-interaction compatible with iPython (and virtually any other | ||
| 1654 | text based shell). | ||
| 1655 | |||
| 1656 | *** Some user options have been replaced/renamed, including (old -> new): | ||
| 1657 | **** python-indent -> python-indent-offset | ||
| 1658 | **** python-guess-indent -> python-indent-guess-indent-offset | ||
| 1659 | **** python-pdbtrack-do-tracking-p -> python-pdbtrack-activate | ||
| 1660 | **** python-use-skeletons -> python-skeleton-autoinsert | ||
| 1661 | |||
| 1662 | *** Some user options have been removed, including: | ||
| 1663 | |||
| 1664 | **** `python-indent-string-contents': Strings are never indented. | ||
| 1665 | |||
| 1666 | **** `python-honour-comment-indentation': | ||
| 1667 | Comments are always considered as indentation markers. | ||
| 1668 | |||
| 1669 | **** `python-continuation-offset': Indentation is automatically | ||
| 1670 | calculated in a pep8 compliant way depending on the context. | ||
| 1671 | |||
| 1672 | **** `python-shell-prompt-alist', `python-shell-continuation-prompt-alist': | ||
| 1673 | Have no direct mapping as the shell interaction is completely different. | ||
| 1674 | |||
| 1675 | **** `python-python-command', `python-jython-command': | ||
| 1676 | Replaced by `python-shell-interpreter'. | ||
| 1677 | |||
| 1678 | **** `inferior-python-filter-regexp', `python-remove-cwd-from-path', | ||
| 1679 | `python-pdbtrack-minor-mode-string', `python-source-modes': | ||
| 1680 | No longer relevant. | ||
| 1681 | |||
| 1682 | *** Some commands have been replaced (old -> new): | ||
| 1683 | **** python-insert-class -> python-skeleton-class | ||
| 1684 | **** python-insert-def -> python-skeleton-def | ||
| 1685 | **** python-insert-for -> python-skeleton-for | ||
| 1686 | **** python-insert-if -> python-skeleton-if | ||
| 1687 | **** python-insert-try/except -> python-skeleton-try | ||
| 1688 | **** python-insert-try/finally -> python-skeleton-try | ||
| 1689 | **** python-insert-while -> python-skeleton-while | ||
| 1690 | **** python-find-function -> python-nav-jump-to-defun | ||
| 1691 | **** python-next-statement -> python-nav-forward-sentence | ||
| 1692 | **** python-previous-statement -> python-nav-backward-sentence | ||
| 1693 | **** python-beginning-of-defun-function -> python-nav-beginning-of-defun | ||
| 1694 | **** python-end-of-defun-function -> python-nav-end-of-defun | ||
| 1695 | **** python-send-buffer -> python-shell-send-buffer | ||
| 1696 | **** python-send-defun -> python-shell-send-defun | ||
| 1697 | **** python-send-region -> python-shell-send-region | ||
| 1698 | **** python-send-region-and-go -> emulate with python-shell-send-region | ||
| 1699 | and python-shell-switch-to-shell | ||
| 1700 | **** python-send-string -> python-shell-send-string | ||
| 1701 | **** python-switch-to-python -> python-shell-switch-to-shell | ||
| 1702 | **** python-describe-symbol -> python-eldoc-at-point | ||
| 1703 | |||
| 1704 | ** D-Bus | ||
| 1705 | |||
| 1706 | *** New variables `dbus-compiled-version' and `dbus-runtime-version'. | ||
| 1707 | |||
| 1708 | *** The D-Bus object manager interface is implemented. | ||
| 1709 | |||
| 1710 | *** Variables of type :(u)int32 and :(u)int64 accept floating points, | ||
| 1711 | if their value does not fit into Emacs's integer range. | ||
| 1712 | |||
| 1713 | *** The function `dbus-call-method' is now non-blocking. | ||
| 1714 | It can be interrupted by `C-g'. `dbus-call-method-non-blocking' is obsolete. | ||
| 1715 | |||
| 1716 | *** Signals can also be sent as unicast messages. | ||
| 1717 | |||
| 1718 | *** The argument list of `dbus-register-signal' has been extended, | ||
| 1719 | according to the new match rule types of D-Bus. | ||
| 1720 | |||
| 1721 | *** `dbus-init-bus' supports private connections. | ||
| 1722 | |||
| 1723 | *** There is a new function `dbus-setenv'. | ||
| 1724 | |||
| 1725 | ** `desktop-path' no longer includes the "." directory. | ||
| 1726 | Desktop files are now located in ~/.emacs.d by default. | ||
| 1727 | |||
| 1728 | ** Dired | ||
| 1729 | |||
| 1730 | *** `dired-do-async-shell-command' executes each file sequentially | ||
| 1731 | if the command ends in `;' (when operating on multiple files). | ||
| 1732 | Otherwise, it executes the command on each file in parallel. | ||
| 1733 | |||
| 1734 | *** Typing `M-n' in the minibuffer of `dired-do-chmod', `dired-do-chgrp', | ||
| 1735 | `dired-do-chown', and `dired-do-touch' yanks the attributes of the | ||
| 1736 | file at point. | ||
| 1737 | |||
| 1738 | *** When the region is active, `m' (`dired-mark'), `u' (`dired-unmark'), | ||
| 1739 | `DEL' (`dired-unmark-backward'), and `d' (`dired-flag-file-deletion') | ||
| 1740 | mark/unmark/flag all files in the active region. | ||
| 1741 | |||
| 1742 | *** The minibuffer default for `=' (`dired-diff') has changed. | ||
| 1743 | It is now the backup file for the file at point, if one exists. | ||
| 1744 | In Transient Mark mode the default is the file at the active mark. | ||
| 1745 | |||
| 1746 | *** `M-=' is no longer bound to `dired-backup-diff' in Dired buffers. | ||
| 1747 | The global binding for `M-=', `count-words-region' is in effect. | ||
| 1748 | |||
| 1749 | ** ERC | ||
| 1750 | |||
| 1751 | *** New module "notifications", which can send a notification when you | ||
| 1752 | receive a private message or your nickname is mentioned. | ||
| 1753 | |||
| 1754 | *** ERC will look up server/channel names via auth-source and use any | ||
| 1755 | channel keys found. | ||
| 1756 | |||
| 1757 | *** New option `erc-lurker-hide-list', similar to `erc-hide-list', but | ||
| 1758 | only applies to messages sent by lurkers. | ||
| 1759 | |||
| 1760 | ** reStructuredText mode | ||
| 1761 | |||
| 1762 | *** Keybindings (see `C-c C-h'), TAB indentation, filling and auto-filling, | ||
| 1763 | fontification, comment handling, and customization have all been revised | ||
| 1764 | and improved. | ||
| 1765 | |||
| 1766 | *** Support for `imenu' and `which-function-mode'. | ||
| 1767 | |||
| 1768 | *** The reStructuredText syntax is more closely covered. | ||
| 1769 | Sphinx support has been improved. | ||
| 1770 | |||
| 1771 | *** `rst-insert-list' inserts new list or continues existing lists. | ||
| 1772 | |||
| 1773 | *** A negative prefix argument always works for `rst-adjust'. | ||
| 1774 | |||
| 1775 | *** The window configuration is reset after displaying a TOC. | ||
| 1776 | |||
| 1777 | *** The constant `rst-version' describes the rst.el package version. | ||
| 1778 | |||
| 1779 | ** Ruby mode | ||
| 1780 | |||
| 1781 | *** Support for percent literals and recognition of regular expressions | ||
| 1782 | in method calls without parentheses with more methods, including Cucumber | ||
| 1783 | steps definitions. | ||
| 1784 | |||
| 1785 | *** Improved syntax highlighting and indentation. | ||
| 1786 | |||
| 1787 | *** New command `ruby-toggle-block', bound to `C-c {'. | ||
| 1788 | |||
| 1789 | *** Some non-standard keybindings/commands have been removed: | ||
| 1790 | |||
| 1791 | **** `ruby-electric-brace'; use `electric-indent-mode' instead. | ||
| 1792 | |||
| 1793 | **** `ruby-mark-defun'; use `mark-defun'. | ||
| 1794 | |||
| 1795 | **** `ruby-beginning-of-defun' and `ruby-end-of-defun' are replaced by | ||
| 1796 | appropriate settings for the variables `beginning-of-defun-function' | ||
| 1797 | and `end-of-defun-function'. | ||
| 1798 | |||
| 1799 | **** Non-standard keybindings for `backward-kill-word', `comment-region', | ||
| 1800 | `reindent-then-newline-and-indent' and `newline' have been removed. | ||
| 1801 | |||
| 1802 | ** Shell Script mode | ||
| 1803 | |||
| 1804 | *** Pairing of parens/quotes uses `electric-pair-mode' instead of skeleton-pair. | ||
| 1805 | |||
| 1806 | *** `sh-electric-here-document-mode' now controls auto-insertion of here-docs. | ||
| 1807 | |||
| 1808 | *** `sh-use-smie' lets you choose a new indentation and navigation code. | ||
| 1809 | |||
| 1810 | ** VHDL mode | ||
| 1811 | |||
| 1812 | *** The free software compiler GHDL is supported (and now the default). | ||
| 1813 | |||
| 1814 | *** Support for the VHDL-AMS packages has been added/updated. | ||
| 1815 | |||
| 1816 | *** Updated to the 2002 revision of the VHDL standard. | ||
| 1817 | |||
| 1818 | *** Accepts \r and \f as whitespace. | ||
| 1819 | |||
| 1820 | ** Apropos | ||
| 1821 | |||
| 1822 | *** The faces used by Apropos are now directly customizable. | ||
| 1823 | These faces are named `apropos-symbol', `apropos-keybinding', and so on; | ||
| 1824 | see the `apropos' Custom group for details. | ||
| 1825 | |||
| 1826 | *** The old options whose values specified faces to use have been removed | ||
| 1827 | (i.e. `apropos-symbol-face', `apropos-keybinding-face', `apropos-label-face', | ||
| 1828 | `apropos-match-face' and `apropos-property-face'.). | ||
| 1829 | |||
| 1830 | ** Buffer Menu | ||
| 1831 | |||
| 1832 | *** This package has been rewritten to use Tabulated List mode. | ||
| 1833 | |||
| 1834 | *** Option `Buffer-menu-buffer+size-width' is now obsolete. | ||
| 1835 | Use `Buffer-menu-name-width' and `Buffer-menu-size-width' instead. | ||
| 1836 | |||
| 1837 | ** Calc | ||
| 1838 | |||
| 1839 | *** Algebraic simplification mode is now the default. | ||
| 1840 | To restrict to the limited simplifications given by the former | ||
| 1841 | default simplification mode, use `m I'. | ||
| 1842 | |||
| 1843 | ** Calendar | ||
| 1844 | |||
| 1845 | *** You can customize the header text that appears above each calendar month. | ||
| 1846 | See the variable `calendar-month-header'. | ||
| 1847 | |||
| 1848 | *** New LaTeX calendar style, produced by `cal-tex-cursor-week2-summary'. | ||
| 1849 | |||
| 1850 | *** The calendars produced by cal-html include holidays. | ||
| 1851 | Customize `cal-html-holidays' to change this. | ||
| 1852 | |||
| 1853 | ** CEDET | ||
| 1854 | |||
| 1855 | *** The major modes from the parser generators "Bovine" and "Wisent" | ||
| 1856 | are now properly integrated in Emacs. The file suffixes ".by" and ".wy" | ||
| 1857 | are in `auto-mode-alist', and the corresponding manuals are included. | ||
| 1858 | |||
| 1859 | *** EDE | ||
| 1860 | |||
| 1861 | **** Menu support for the "Configuration" feature. This allows users to | ||
| 1862 | choose the active configuration (such as debug or install) from the menu. | ||
| 1863 | |||
| 1864 | **** New command `ede-set' to interactively set project-local variables. | ||
| 1865 | |||
| 1866 | **** Support for compiling, debugging, and running in "generic" projects. | ||
| 1867 | |||
| 1868 | **** Autoconf editing support for M4 macros with complex arguments. | ||
| 1869 | |||
| 1870 | **** Compilation support for the "linux" project type. | ||
| 1871 | |||
| 1872 | **** "simple" projects have been removed; use "generic" projects instead. | ||
| 1873 | |||
| 1874 | *** Semantic | ||
| 1875 | |||
| 1876 | **** Support for parsing #include statements inside a namespace in C/C++. | ||
| 1877 | |||
| 1878 | **** Improved support for 'extern "C"' declarations in C/C++. | ||
| 1879 | |||
| 1880 | **** The ability to ignore more common special C/C++ preprocessor symbols, | ||
| 1881 | such as '__nonnull' and '__asm'. Add '__cplusplus' macro when parsing C++. | ||
| 1882 | If available, include cdefs.h as an additional source of preprocessor symbols. | ||
| 1883 | |||
| 1884 | **** Improved C/C++ function pointer parsing. | ||
| 1885 | |||
| 1886 | **** In Python, support for converting imports to include file names. | ||
| 1887 | |||
| 1888 | **** Ability to dynamically determine the Python load path. | ||
| 1889 | |||
| 1890 | **** Support for the Python 'WITH' and 'AT' keywords. | ||
| 1891 | |||
| 1892 | **** Improved tooltip completion. | ||
| 1893 | |||
| 1894 | *** SRecode | ||
| 1895 | |||
| 1896 | **** The SRecode manual is now included. | ||
| 1897 | |||
| 1898 | **** Tag generation supports constructor/destructor settings and system | ||
| 1899 | include differentiation. | ||
| 1900 | |||
| 1901 | **** Addition of 'Framework' support: Frameworks are specified when a | ||
| 1902 | particular kind of library (such as Android) is needed in a common language | ||
| 1903 | mode (like Java). | ||
| 1904 | |||
| 1905 | **** Support for nested templates and let variables override based on priority. | ||
| 1906 | |||
| 1907 | **** Support for merging tables from multiple related modes, such as | ||
| 1908 | default -> c++ -> arduino. | ||
| 1909 | |||
| 1910 | ** Compile has a new option `compilation-always-kill'. | ||
| 1911 | |||
| 1912 | ** Customize | ||
| 1913 | |||
| 1914 | *** `custom-reset-button-menu' now defaults to t. | ||
| 1915 | |||
| 1916 | *** Non-option variables are never matched in `customize-apropos' and | ||
| 1917 | `customize-apropos-options' (i.e., the prefix argument does nothing for | ||
| 1918 | these commands now). | ||
| 1919 | |||
| 1920 | ** Term | ||
| 1921 | |||
| 1922 | *** The variables `term-default-fg-color' and `term-default-bg-color' | ||
| 1923 | are now deprecated in favor of the customizable face `term'. | ||
| 1924 | |||
| 1925 | *** You can customize how to display ANSI terminal colors and styles | ||
| 1926 | by customizing the corresponding `term-color-<COLOR>', | ||
| 1927 | `term-color-underline' and `term-color-bold' faces. | ||
| 1928 | |||
| 1929 | ** Tramp | ||
| 1930 | |||
| 1931 | *** The syntax has been extended in order to allow ad-hoc proxy definitions. | ||
| 1932 | |||
| 1933 | *** Remote processes are now also supported on remote MS-Windows hosts. | ||
| 1934 | |||
| 1935 | ** URL | ||
| 1936 | |||
| 1937 | *** Structs made by `url-generic-parse-url' have nil `attributes' slot. | ||
| 1938 | Previously, this slot stored semicolon-separated attribute-value pairs | ||
| 1939 | appended to some imap URLs, but this is not compatible with RFC 3986. | ||
| 1940 | So now the `filename' slot stores the entire path and query components, | ||
| 1941 | and the `attributes' slot is always nil. | ||
| 1942 | |||
| 1943 | *** New function `url-encode-url' for encoding a URI string. | ||
| 1944 | The `url-retrieve' function now uses this to encode its URL argument, | ||
| 1945 | in case that is not properly encoded. | ||
| 1946 | |||
| 1947 | ** notifications.el supports now version 1.2 of the Notifications API. | ||
| 1948 | The function `notifications-get-capabilities' returns the supported | ||
| 1949 | server properties. | ||
| 1950 | |||
| 1951 | ** Flymake uses fringe bitmaps to indicate errors and warnings. | ||
| 1952 | See `flymake-fringe-indicator-position', `flymake-error-bitmap' and | ||
| 1953 | `flymake-warning-bitmap'. | ||
| 1954 | |||
| 1955 | ** The FFAP option `ffap-url-unwrap-remote' can now be a list of strings, | ||
| 1956 | specifying URL types that should be converted to remote file names at | ||
| 1957 | the FFAP prompt. The default is now '("ftp"). | ||
| 1958 | |||
| 1959 | ** New Ibuffer `derived-mode' filter, bound to `/ M'. | ||
| 1960 | The old binding for `/ M' (filter by used-mode) is now bound to `/ m'. | ||
| 1961 | |||
| 1962 | ** New option `mouse-avoidance-banish-position' specifies where the | ||
| 1963 | `banish' mouse avoidance setting moves the mouse. | ||
| 1964 | |||
| 1965 | ** In Perl mode, new option `perl-indent-parens-as-block' causes non-block | ||
| 1966 | closing brackets to be aligned with the line of the opening bracket. | ||
| 1967 | |||
| 1968 | ** In Proced mode, new command `proced-renice' renices marked processes. | ||
| 1969 | |||
| 1970 | ** New option `async-shell-command-buffer' specifies the buffer to use | ||
| 1971 | for a new asynchronous `shell-command' when the default output buffer | ||
| 1972 | `*Async Shell Command*' is already in use. | ||
| 1973 | |||
| 1974 | ** SQL mode has a new option `sql-db2-escape-newlines'. | ||
| 1975 | If non-nil, newlines sent to the command interpreter will be escaped | ||
| 1976 | by a backslash. The default does not escape the newlines and assumes | ||
| 1977 | that the sql statement will be terminated by a semicolon. | ||
| 1978 | |||
| 1979 | ** New command `tabulated-list-sort', bound to `S' in Tabulated List mode | ||
| 1980 | (and modes that derive from it), sorts the column at point, or the Nth | ||
| 1981 | column if a numeric prefix argument is given. | ||
| 1982 | |||
| 1983 | ** `which-func-modes' now defaults to t, so Which Function mode, when | ||
| 1984 | enabled, applies to all applicable major modes. | ||
| 1985 | |||
| 1986 | ** `winner-mode-hook' now runs when the mode is disabled, as well as when | ||
| 1987 | it is enabled. | ||
| 1988 | |||
| 1989 | ** Follow mode no longer works by using advice. | ||
| 1990 | The option `follow-intercept-processes' has been removed. | ||
| 1991 | |||
| 1992 | ** `javascript-generic-mode' is now an obsolete alias for `js-mode'. | ||
| 1993 | |||
| 1994 | ** Hooks renamed to avoid obsolete "-hooks" suffix: | ||
| 1995 | *** semantic-lex-reset-hooks -> semantic-lex-reset-functions | ||
| 1996 | *** semantic-change-hooks -> semantic-change-functions | ||
| 1997 | *** semantic-edits-new-change-hooks -> semantic-edits-new-change-functions | ||
| 1998 | *** semantic-edits-delete-change-hooks -> semantic-edits-delete-change-functions | ||
| 1999 | *** semantic-edits-reparse-change-hooks -> semantic-edits-reparse-change-functions | ||
| 2000 | *** semanticdb-save-database-hooks -> semanticdb-save-database-functions | ||
| 2001 | *** c-prepare-bug-report-hooks -> c-prepare-bug-report-hook | ||
| 2002 | *** rcirc-sentinel-hooks -> rcirc-sentinel-functions | ||
| 2003 | *** rcirc-receive-message-hooks -> rcirc-receive-message-functions | ||
| 2004 | *** rcirc-activity-hooks -> rcirc-activity-functions | ||
| 2005 | *** rcirc-print-hooks -> rcirc-print-functions | ||
| 2006 | *** dbus-event-error-hooks -> dbus-event-error-functions | ||
| 2007 | *** eieio-pre-method-execution-hooks -> eieio-pre-method-execution-functions | ||
| 2008 | *** checkdoc-style-hooks -> checkdoc-style-functions | ||
| 2009 | *** checkdoc-comment-style-hooks -> checkdoc-comment-style-functions | ||
| 2010 | *** archive-extract-hooks -> archive-extract-hook | ||
| 2011 | *** filesets-cache-fill-content-hooks -> filesets-cache-fill-content-hook | ||
| 2012 | *** hfy-post-html-hooks -> hfy-post-html-hook | ||
| 2013 | *** nndiary-request-create-group-hooks -> nndiary-request-create-group-functions | ||
| 2014 | *** nndiary-request-update-info-hooks -> nndiary-request-update-info-functions | ||
| 2015 | *** nndiary-request-accept-article-hooks -> nndiary-request-accept-article-functions | ||
| 2016 | *** gnus-subscribe-newsgroup-hooks -> gnus-subscribe-newsgroup-functions | ||
| 2017 | |||
| 2018 | ** Obsolete packages | ||
| 2019 | |||
| 2020 | *** assoc.el | ||
| 2021 | In most cases, assoc+member+push+delq work just as well. | ||
| 2022 | And in any case it's just a terrible package: ugly semantics, terrible | ||
| 2023 | inefficiency, and not namespace-clean. | ||
| 2024 | *** bruce.el | ||
| 2025 | *** cust-print.el | ||
| 2026 | *** ledit.el | ||
| 2027 | *** mailpost.el | ||
| 2028 | *** mouse-sel.el | ||
| 2029 | *** patcomp.el | ||
| 2030 | |||
| 2031 | |||
| 2032 | * Incompatible Lisp Changes in Emacs 24.3 | ||
| 2033 | |||
| 2034 | ** Docstrings starting with `*' no longer indicate user options. | ||
| 2035 | Only variables defined using `defcustom' are considered user options. | ||
| 2036 | The function `user-variable-p' is now an obsolete alias for | ||
| 2037 | `custom-variable-p'. | ||
| 2038 | |||
| 2039 | ** The return values of `defalias', `defun' and `defmacro' have changed, | ||
| 2040 | and are now undefined. For backwards compatibility, `defun' and | ||
| 2041 | `defmacro' currently return the name of the newly defined | ||
| 2042 | function/macro, but this should not be relied upon. | ||
| 2043 | |||
| 2044 | ** `random' by default now returns a different random sequence in | ||
| 2045 | every Emacs run. Use `(random S)', where S is a string, to set the | ||
| 2046 | random seed to a value based on S, in order to get a repeatable | ||
| 2047 | sequence in later calls. | ||
| 2048 | |||
| 2049 | ** If the NEWTEXT arg to `replace-match' contains a substring "\?", | ||
| 2050 | that substring is inserted literally even if the LITERAL arg is | ||
| 2051 | non-nil, instead of causing an error to be signaled. | ||
| 2052 | |||
| 2053 | ** `select-window' now always makes the window's buffer current. | ||
| 2054 | It does so even if the window was selected before. | ||
| 2055 | |||
| 2056 | ** The function `x-select-font' can return a font spec, instead of a | ||
| 2057 | font name as a string. Whether it returns a font spec or a font name | ||
| 2058 | depends on the graphical library. | ||
| 2059 | |||
| 2060 | ** `face-spec-set' no longer sets frame-specific attributes when the | ||
| 2061 | third argument is a frame (that usage was obsolete since Emacs 22.2). | ||
| 2062 | |||
| 2063 | ** `set-buffer-multibyte' now signals an error in narrowed buffers. | ||
| 2064 | |||
| 2065 | ** The CL package's `get-setf-method' function no longer exists. | ||
| 2066 | Generalized variables are now part of core Emacs Lisp, and implemented | ||
| 2067 | differently to the way cl.el used to do it. It is not possible to | ||
| 2068 | define a compatible replacement for `get-setf-method'. See the file | ||
| 2069 | gv.el for internal details of the new implementation. | ||
| 2070 | |||
| 2071 | ** The arguments of `dbus-register-signal' are no longer just strings, | ||
| 2072 | but keywords or keyword-string pairs. The old argument list will | ||
| 2073 | still be supported for Emacs 24.x. | ||
| 2074 | |||
| 2075 | ** Miscellaneous name changes | ||
| 2076 | Some Lisp symbols have been renamed to correct their spelling, | ||
| 2077 | or to be more consistent with standard Emacs terminology. | ||
| 2078 | |||
| 2079 | *** Renamed functions | ||
| 2080 | **** hangul-input-method-inactivate -> hangul-input-method-deactivate | ||
| 2081 | **** inactivate-input-method -> deactivate-input-method | ||
| 2082 | **** quail-inactivate -> quail-deactivate | ||
| 2083 | **** robin-inactivate -> robin-deactivate | ||
| 2084 | **** viper-inactivate-input-method -> viper-deactivate-input-method | ||
| 2085 | **** viper-inactivate-input-method-action -> | ||
| 2086 | viper-deactivate-input-method-action | ||
| 2087 | **** ucs-input-inactivate -> ucs-input-deactivate | ||
| 2088 | |||
| 2089 | *** Renamed hooks | ||
| 2090 | The old hooks are still supported for backward compatibility, but they | ||
| 2091 | are deprecated and will be removed eventually. | ||
| 2092 | **** input-method-inactivate-hook -> input-method-deactivate-hook | ||
| 2093 | **** robin-inactivate-hook -> robin-deactivate-hook | ||
| 2094 | **** quail-inactivate-hook -> quail-deactivate-hook | ||
| 2095 | |||
| 2096 | *** Renamed variables | ||
| 2097 | **** follow-deactive-menu -> follow-inactive-menu | ||
| 2098 | **** inactivate-current-input-method-function -> | ||
| 2099 | deactivate-current-input-method-function | ||
| 2100 | |||
| 2101 | ** Some obsolete functions, variables, and faces have been removed: | ||
| 2102 | *** `last-input-char', `last-command-char', `unread-command-char' | ||
| 2103 | *** `facemenu-unlisted-faces' | ||
| 2104 | *** `rmail-decode-mime-charset' | ||
| 2105 | *** `iswitchb-read-buffer' | ||
| 2106 | *** `sc-version', `sc-submit-bug-report' | ||
| 2107 | *** `set-char-table-default' | ||
| 2108 | *** `string-to-sequence' (use `string-to-list' or `string-to-vector') | ||
| 2109 | *** `compile-internal' | ||
| 2110 | *** `modeline' | ||
| 2111 | *** `mode-line-inverse-video' | ||
| 2112 | *** `follow-mode-off-hook' | ||
| 2113 | *** `cvs-commit-buffer-require-final-newline' | ||
| 2114 | (use `log-edit-require-final-newline' instead) | ||
| 2115 | *** `cvs-changelog-full-paragraphs' | ||
| 2116 | (use `log-edit-changelog-full-paragraphs' instead) | ||
| 2117 | *** `cvs-diff-ignore-marks', `cvs-diff-buffer-name' | ||
| 2118 | *** `vc-ignore-vc-files' (use `vc-handled-backends' instead) | ||
| 2119 | *** `vc-master-templates' (use `vc-handled-backends' instead) | ||
| 2120 | *** `vc-checkout-carefully' | ||

| 2125 | ** CL-style generalized variables are now in core Elisp. | ||
| 2126 | `setf' is autoloaded; `push' and `pop' accept generalized variables. | ||
| 2127 | You can define your own generalized variables using `gv-define-simple-setter', | ||
| 2128 | `gv-define-setter', etc. | ||
| 2129 | |||
| 2130 | ** Emacs tries to macroexpand interpreted (non-compiled) files during load. | ||
| 2131 | This can significantly speed up execution of non-byte-compiled code, | ||
| 2132 | but can also bump into previously unnoticed cyclic dependencies. | ||
| 2133 | These are generally harmless: they will simply cause the macro calls | ||
| 2134 | to be left for later expansion (as before), but will result in a | ||
| 2135 | warning ("Eager macro-expansion skipped due to cycle") describing the cycle. | ||
| 2136 | You may wish to restructure your code so this does not happen. | ||
| 2137 | |||
| 2138 | ** New sampling-based Elisp profiler. | ||
| 2139 | Try M-x profiler-start, do some work, and then call M-x profiler-report. | ||
| 2140 | When finished, use M-x profiler-stop. The sampling rate can be based on | ||
| 2141 | CPU time or memory allocations. | ||
| 2142 | |||
| 2143 | ** `defun' also accepts a (declare DECLS) form, like `defmacro'. | ||
| 2144 | The interpretation of the DECLS is determined by `defun-declarations-alist'. | ||
| 2145 | |||
| 2146 | ** New macros `setq-local' and `defvar-local'. | ||
| 2147 | |||
| 2148 | ** Face underlining can now use a wave. | ||
| 2149 | |||
| 2150 | ** `read-regexp' has a new argument HISTORY; the first argument PROMPT | ||
| 2151 | of `read-regexp' accepts a string ending with a colon and space, and its | ||
| 2152 | second argument DEFAULTS can be a list of strings accessible via `M-n' | ||
| 2153 | in the minibuffer ahead of other hard-coded useful regexp-related values. | ||
| 2154 | More commands use `read-regexp' now to read their regexp arguments. | ||
| 2155 | |||
| 2156 | ** Completion | ||
| 2157 | |||
| 2158 | *** New function `completion-table-with-quoting' to handle completion | ||
| 2159 | in the presence of quoting, such as file completion in shell buffers. | ||
| 2160 | |||
| 2161 | *** New function `completion-table-subvert' to use an existing completion | ||
| 2162 | table, but with a different prefix. | ||
| 2163 | |||
| 2164 | ** Debugger | ||
| 2165 | |||
| 2166 | *** New error type and new function `user-error'. | ||
| 2167 | These do not trigger the debugger. | ||
| 2168 | |||
| 2169 | *** New option `debugger-bury-or-kill', saying what to do with the | ||
| 2170 | debugger buffer when exiting debug. | ||
| 2171 | |||
| 2172 | *** Set `debug-on-message' to enter the debugger when a certain | ||
| 2173 | message is displayed in the echo area. This can be useful when trying | ||
| 2174 | to work out which code is doing something. | ||
| 2175 | |||
| 2176 | *** New var `inhibit-debugger', automatically set to prevent accidental | ||
| 2177 | recursive invocations. | ||
| 2178 | |||
| 2179 | ** Window handling | ||
| 2180 | |||
| 2181 | *** New command `fit-frame-to-buffer' adjusts the frame height to | ||
| 2182 | fit the contents. | ||
| 2183 | |||
| 2184 | *** The command `fit-window-to-buffer' can adjust the frame height | ||
| 2185 | if the new option `fit-frame-to-buffer' is non-nil. | ||
| 2186 | |||
| 2187 | *** New macro `with-temp-buffer-window', similar to | ||
| 2188 | `with-output-to-temp-buffer'. | ||
| 2189 | |||
| 2190 | *** `temp-buffer-resize-mode' no longer resizes windows that have been | ||
| 2191 | reused. | ||
| 2192 | |||
| 2193 | *** New option `switch-to-buffer-preserve-window-point' to restore a | ||
| 2194 | window's point when switching buffers. | ||
| 2195 | |||
| 2196 | *** New display action alist entries `window-height' and `window-width' | ||
| 2197 | specify the size of new windows created by `display-buffer'. | ||
| 2198 | |||
| 2199 | *** New display action alist entry `pop-up-frame-parameters', if | ||
| 2200 | non-nil, specifies frame parameters to give any newly-created frame. | ||
| 2201 | |||
| 2202 | *** New display action alist entry `inhibit-switch-frame', if non-nil, | ||
| 2203 | tells display action functions to avoid changing which frame is | ||
| 2204 | selected. | ||
| 2205 | |||
| 2206 | *** New display action alist entry `previous-window', if non-nil, | ||
| 2207 | specifies window to reuse in `display-buffer-in-previous-window'. | ||
| 2208 | |||
| 2209 | *** New display action functions `display-buffer-below-selected', | ||
| 2210 | and `display-buffer-in-previous-window'. | ||
| 2211 | |||
| 2212 | *** The functions `get-lru-window', `get-mru-window' and `get-largest-window' | ||
| 2213 | now accept a third argument to avoid choosing the selected window. | ||
| 2214 | |||
| 2215 | *** Additional values recognized for option `window-combination-limit'. | ||
| 2216 | |||
| 2217 | *** The following variables are obsolete, as they can be replaced by | ||
| 2218 | appropriate entries in the `display-buffer-alist' function introduced | ||
| 2219 | in Emacs 24.1: | ||
| 2220 | **** `dired-shrink-to-fit' | ||
| 2221 | **** `display-buffer-reuse-frames' | ||
| 2222 | **** `display-buffer-function' | ||
| 2223 | **** `special-display-buffer-names' | ||
| 2224 | **** `special-display-frame-alist' | ||
| 2225 | **** `special-display-function' | ||
| 2226 | **** `special-display-regexps' | ||
| 2227 | |||
| 2228 | ** Time | ||
| 2229 | |||
| 2230 | *** `current-time-string' no longer requires that its argument's year | ||
| 2231 | must be in the range 1000..9999. It now works with any year supported | ||
| 2232 | by the underlying C implementation. | ||
| 2233 | |||
| 2234 | *** `current-time' now returns extended-format time stamps | ||
| 2235 | (HIGH LOW USEC PSEC), where the new PSEC slot specifies picoseconds. | ||
| 2236 | PSEC is typically a multiple of 1000 on current machines. Other | ||
| 2237 | functions that use this format, such as `file-attributes' and | ||
| 2238 | `format-time-string', have been changed accordingly. Old-format time | ||
| 2239 | stamps are still accepted. | ||
| 2240 | |||
| 2241 | *** The format of timers in `timer-list' and `timer-idle-list' is now | ||
| 2242 | [TRIGGERED-P HI-SECS LO-SECS USECS REPEAT-DELAY FUNCTION ARGS IDLE-DELAY PSECS]. | ||
| 2243 | The PSECS slot is new, and uses picosecond resolution. It can be | ||
| 2244 | accessed via the new `timer--psecs' accessor. | ||
| 2245 | |||
| 2246 | *** Last-modified time stamps in undo lists now are of the form | ||
| 2247 | (t HI-SECS LO-SECS USECS PSECS) instead of (t HI-SECS . LO-SECS). | ||
| 2248 | |||
| 2249 | ** EIEIO | ||
| 2250 | |||
| 2251 | *** Improved security when handling persistent objects: | ||
| 2252 | |||
| 2253 | **** `eieio-persistent-read' now features optional arguments for specifying | ||
| 2254 | the class to load, as well as a flag stating whether subclasses are allowed; | ||
| 2255 | if provided, other classes will be rejected by the reader. For | ||
| 2256 | compatibility with existing code, if the class is omitted only a | ||
| 2257 | warning is issued. | ||
| 2258 | |||
| 2259 | **** New specialized reader for pulling in classes and signaling errors | ||
| 2260 | without evaluation of suspicious code. | ||
| 2261 | |||
| 2262 | **** All slots that contain objects must have a :type. Slots with lists | ||
| 2263 | of objects must use a new type predicate for a list of an object type. | ||
| 2264 | |||
| 2265 | *** Support for `find-function' and similar utilities, through the addition | ||
| 2266 | of filename support to generated symbols. | ||
| 2267 | |||
| 2268 | ** Floating point functions now always return special values like NaN, | ||
| 2269 | instead of signaling errors, if given invalid args; e.g., (log -1.0). | ||
| 2270 | Previously, they returned NaNs on some platforms but signaled errors | ||
| 2271 | on others. The affected functions are acos, asin, tan, exp, expt, | ||
| 2272 | log, log10, sqrt, and mod. | ||
| 2273 | |||
| 2274 | ** New fringe bitmap `exclamation-mark'. | ||
| 2275 | |||
| 2276 | ** Miscellaneous changes to special forms and macros | ||
| 2277 | |||
| 2278 | *** `defun' and `defmacro' are now macros rather than special forms. | ||
| 2279 | |||
| 2280 | *** `kbd' is now a function rather than a macro. | ||
| 2281 | |||
| 2282 | ** Miscellaneous new functions | ||
| 2283 | |||
| 2284 | *** `set-temporary-overlay-map' sets up a temporary keymap that | ||
| 2285 | takes precedence over most other maps for a short while (normally one key). | ||
| 2286 | |||
| 2287 | *** `autoloadp' tests if its argument is an autoloaded object. | ||
| 2288 | |||
| 2289 | *** `autoload-do-load' performs the autoloading operation. | ||
| 2290 | |||
| 2291 | *** `buffer-narrowed-p' tests if the buffer is narrowed. | ||
| 2292 | |||
| 2293 | *** `file-name-base' returns a file name sans directory and extension. | ||
| 2294 | |||
| 2295 | *** `function-get' fetches a function property, following aliases. | ||
| 2296 | |||
| 2297 | *** `posnp' tests if an object is a `posn'. | ||
| 2298 | |||
| 2299 | *** `system-users' returns the user names on the system. | ||
| 2300 | |||
| 2301 | *** `system-groups' returns the group names on the system. | ||
| 2302 | |||
| 2303 | *** `tty-top-frame' returns the topmost frame of a text terminal. | ||
| 2304 | |||
| 2305 | ** The following functions and variables are obsolete: | ||
| 2306 | *** `automount-dir-prefix' (use `directory-abbrev-alist') | ||
| 2307 | *** `buffer-has-markers-at' | ||
| 2308 | *** `macro-declaration-function' (use `macro-declarations-alist') | ||
| 2309 | *** `window-system-version' (provides no useful information) | ||
| 2310 | *** `dired-pop-to-buffer' (use `dired-mark-pop-up') | ||
| 2311 | *** `query-replace-interactive' | ||
| 2312 | *** `font-list-limit' (has had no effect since Emacs < 23) | ||
| 2313 | |||
| 2314 | |||
| 2315 | * Changes in Emacs 24.3 on Non-Free Operating Systems | ||
| 2316 | |||
| 2317 | ** Cygwin builds can use the native MS Windows user interface. | ||
| 2318 | Pass `--with-w32' to configure. The default remains the X11 interface. | ||
| 2319 | |||
| 2320 | ** Two new functions are available in Cygwin builds: | ||
| 2321 | `cygwin-convert-file-name-from-windows' and | ||
| 2322 | `cygwin-convert-file-name-to-windows'. These functions allow Lisp | ||
| 2323 | code to access the Cygwin file-name mapping machinery to convert | ||
| 2324 | between Cygwin and Windows-native file and directory names. | ||
| 2325 | |||
| 2326 | ** When invoked with the -nw switch to run on the Windows text-mode terminal, | ||
| 2327 | Emacs now supports `mouse-highlight', help-echo (in the echo area), and | ||
| 2328 | `mouse-autoselect-window'. | ||
| 2329 | |||
| 2330 | ** On MS Windows Vista and later Emacs now supports symbolic links. | ||
| 2331 | |||
| 2332 | ** On MS Windows, you can pass `--without-libxml2' to configure.bat to omit | ||
| 2333 | support for libxml2, even if its presence is detected. | ||
| 2334 | |||
| 2335 | ** On Mac OS X, the Nextstep port requires OS X 10.4 or later. | ||
| 2336 | |||
| 2337 | ** On Mac OS X, configure no longer automatically adds the Fink "/sw" | ||
| 2338 | directories to the search path. You must add them yourself if you want them. | ||
| 2339 | |||
| 2340 | |||
| 2341 | * Changes in Emacs 24.2 | ||
| 2342 | |||
| 2343 | ** This is mainly a bug-fix release. | ||
| 2344 | |||
| 2345 | |||
| 2346 | * Installation Changes in Emacs 24.1 | ||
| 2347 | |||
| 2348 | ** Emacs can be compiled with Gtk+ 3.0 if you pass --with-x-toolkit=gtk3 | ||
| 2349 | to configure. Note that other libraries used by Emacs, RSVG and GConf, | ||
| 2350 | also depend on Gtk+. You can disable them with --without-rsvg and | ||
| 2351 | --without-gconf. | ||
| 2352 | |||
| 2353 | ** Emacs can be compiled with GnuTLS support. | ||
| 2354 | This happens by default if a suitably recent version of the library is | ||
| 2355 | found at build time. To prevent this, use the configure option | ||
| 2356 | `--without-gnutls'. See below for GnuTLS features. | ||
| 2357 | |||
| 2358 | ** Emacs can be compiled with SELinux support. | ||
| 2359 | This happens by default if a suitably recent version of the library is | ||
| 2360 | found at build time. To prevent this, use the configure option | ||
| 2361 | `--without-selinux'. See below for SELinux features. | ||
| 2362 | |||
| 2363 | ** Emacs can be compiled with ImageMagick support. | ||
| 2364 | This happens by default if a suitably recent version of the library is | ||
| 2365 | found at build time. To prevent this, use the configure option | ||
| 2366 | `--without-imagemagick'. See below for ImageMagick features. | ||
| 2367 | This feature is not available for the Nextstep or MS ports. | ||
| 2368 | |||
| 2369 | ** Emacs can be compiled with libxml2 support. | ||
| 2370 | This happens by default if a suitably recent version of the library is | ||
| 2371 | found at build time. To prevent this, use the configure option | ||
| 2372 | `--without-xml2'. See below for libxml2 features. | ||
| 2373 | |||
| 2374 | ** By default, the installed Info and man pages are compressed. | ||
| 2375 | You can disable this by configuring --without-compress-info. | ||
| 2376 | |||
| 2377 | ** New configure option --with-wide-int. | ||
| 2378 | With it, Emacs integers typically have 62 bits, even on 32-bit machines. | ||
| 2379 | On 32-bit hosts, this raises the limit on buffer sizes from about 512 MiB | ||
| 2380 | to about 2 GiB. | ||
| 2381 | |||
| 2382 | ** New configure options: --with-mmdf, --with-mail-unlink, --with-mailhost. | ||
| 2383 | These provide no new functionality, they just remove the need to edit | ||
| 2384 | lib-src/Makefile by hand in order to use the associated features. | ||
| 2385 | |||
| 2386 | ** New configure option --enable-use-lisp-union-type. | ||
| 2387 | This is only useful for Emacs developers to debug certain types of bugs. | ||
| 2388 | This is not a new feature; only the configure flag is new. | ||
| 2389 | |||
| 2390 | ** The standalone programs digest-doc and sorted-doc are removed. | ||
| 2391 | Emacs now uses Lisp commands `doc-file-to-man' and `doc-file-to-info'. | ||
| 2392 | |||
| 2393 | ** The standalone program `fakemail' is removed. | ||
| 2394 | If you need it, feedmail.el provides a superset of the functionality. | ||
| 2395 | |||
| 2396 | |||
| 2397 | * Startup Changes in Emacs 24.1 | ||
| 2398 | |||
| 2399 | ** The --unibyte, --multibyte, --no-multibyte, and --no-unibyte | ||
| 2400 | command line arguments, and the EMACS_UNIBYTE environment variable, no | ||
| 2401 | longer have any effect. (They were declared obsolete in Emacs 23.) | ||
| 2402 | |||
| 2403 | ** New command line option `--no-site-lisp' removes site-lisp directories | ||
| 2404 | from load-path. -Q now implies this. This option does not affect the | ||
| 2405 | EMACSLOADPATH environment variable (and hence has no effect for | ||
| 2406 | Nextstep builds). | ||
| 2407 | |||
| 2408 | |||
| 2409 | * Changes in Emacs 24.1 | ||
| 2410 | |||
| 2411 | ** Completion | ||
| 2412 | |||
| 2413 | *** Many packages now use the `completion-at-point' command, | ||
| 2414 | rather than implementing separate completion commands. | ||
| 2415 | |||
| 2416 | *** `completion-at-point' now handles tags and semantic completion. | ||
| 2417 | |||
| 2418 | *** Completion in a non-minibuffer now tries to detect the end of completion | ||
| 2419 | and pops down the *Completions* buffer accordingly. | ||
| 2420 | |||
| 2421 | *** New option `completion-cycle-threshold' allows completion cycling. | ||
| 2422 | |||
| 2423 | *** New option `completion-category-overrides' for overriding the | ||
| 2424 | default completion style in certain circumstances. | ||
| 2425 | |||
| 2426 | *** New completion style `substring'. | ||
| 2427 | |||
| 2428 | *** Completion of buffer names uses `substring' completion by default. | ||
| 2429 | |||
| 2430 | *** The option `widget-complete-field' has been removed. | ||
| 2431 | |||
| 2432 | ** Mail changes | ||
| 2433 | |||
| 2434 | *** The first time you try sending mail, Emacs asks for a mail method. | ||
| 2435 | This is implemented by a new default for `send-mail-function', which | ||
| 2436 | is `sendmail-query-once'. This offers to use the smtpmail package, or | ||
| 2437 | to use the old defaults relying on external mail facilities | ||
| 2438 | (`sendmail-send-it' on GNU/Linux and other Unix-like systems, and | ||
| 2439 | `mailclient-send-it' on Windows). | ||
| 2440 | |||
| 2441 | *** Typing `C-c m' in the buffer made by `M-x report-emacs-bug' | ||
| 2442 | transfers the report to your desktop's preferred mail client, if there | ||
| 2443 | is one. This uses either the "xdg-email" utility, or Mac OS's "open" | ||
| 2444 | command. | ||
| 2445 | |||
| 2446 | *** See Changes in Specialized Modes and Packages for SMTPmail changes | ||
| 2447 | and Mail mode changes | ||
| 2448 | |||
| 2449 | ** Emacs server and client changes | ||
| 2450 | |||
| 2451 | *** New option `server-port' specifies the port for TCP Emacs servers. | ||
| 2452 | |||
| 2453 | *** New emacsclient argument -q/--quiet suppresses some status messages. | ||
| 2454 | |||
| 2455 | *** New emacsclient argument --frame-parameters specifies the frame | ||
| 2456 | parameters of any newly-created graphical frame. | ||
| 2457 | |||
| 2458 | *** If emacsclient shuts down due to Emacs signaling an error, | ||
| 2459 | its exit status is 1. | ||
| 2460 | |||
| 2461 | *** New emacsclient argument --parent-id ID. | ||
| 2462 | This opens a client frame in parent X window ID, via XEmbed, similar | ||
| 2463 | to the --parent-id argument to Emacs. | ||
| 2464 | |||
| 2465 | ** Internationalization changes | ||
| 2466 | |||
| 2467 | *** Emacs now supports display and editing of bidirectional text. | ||
| 2468 | Right-to-left (RTL) scripts, such as Arabic, Farsi, and Hebrew, are | ||
| 2469 | displayed in the correct visual order as expected by users of those | ||
| 2470 | scripts. The display reordering is a "full bidirectionality" class | ||
| 2471 | implementation of the Unicode Bidirectional Algorithm (UBA). Buffers | ||
| 2472 | with no RTL text should look exactly the same as before. | ||
| 2473 | |||
| 2474 | **** New buffer-local variable `bidi-display-reordering'. | ||
| 2475 | To disable display reordering in a buffer, change this to nil. | ||
| 2476 | |||
| 2477 | **** New buffer-local variable `bidi-paragraph-direction'. | ||
| 2478 | If nil (the default), Emacs determines the base direction of each | ||
| 2479 | paragraph from its text, as specified by the UBA. Setting the value | ||
| 2480 | to `right-to-left' or `left-to-right' forces a base direction on each | ||
| 2481 | paragraph. | ||
| 2482 | |||
| 2483 | Paragraphs with right-to-left base direction are displayed starting at | ||
| 2484 | the right window edge. | ||
| 2485 | |||
| 2486 | *** Enhanced support for characters with no glyphs in available fonts, | ||
| 2487 | or, on text terminals, characters that cannot be encoded by the | ||
| 2488 | terminal coding system. The new option `glyphless-char-display-control' | ||
| 2489 | specifies how to display them: as a hexadecimal code in a box, a thin | ||
| 2490 | 1-pixel space, an empty box, etc. | ||
| 2491 | |||
| 2492 | *** New input methods for Farsi and Bulgarian | ||
| 2493 | (farsi-isiri-9147, farsi-transliterate-banan, bulgarian-alt-phonetic). | ||
| 2494 | |||
| 2495 | *** `nobreak-char-display' now also highlights Unicode hyphen chars | ||
| 2496 | (U+2010 and U+2011). | ||
| 2497 | |||
| 2498 | *** New Hebrew translation of the Emacs Tutorial. | ||
| 2499 | Type `C-u C-h t' to choose it in case your language setup doesn't | ||
| 2500 | automatically select it. | ||
| 2501 | |||
| 2502 | ** An Emacs Lisp package manager is now included. | ||
| 2503 | This is a convenient way to download and install additional packages, | ||
| 2504 | from a package repository at http://elpa.gnu.org. | ||
| 2505 | |||
| 2506 | *** M-x list-packages shows a list of packages, which can be | ||
| 2507 | selected for installation. | ||
| 2508 | |||
| 2509 | *** New command `describe-package', bound to `C-h P'. | ||
| 2510 | |||
| 2511 | *** By default, all installed packages are loaded automatically when | ||
| 2512 | Emacs starts up. To disable this, set `package-enable-at-startup' to | ||
| 2513 | nil. To specify the packages to load, customize `package-load-list'. | ||
| 2514 | |||
| 2515 | ** Custom theme changes | ||
| 2516 | |||
| 2517 | *** New command `M-x customize-themes', which provides a convenient | ||
| 2518 | interface for enabling and disabling Custom themes. | ||
| 2519 | |||
| 2520 | *** New option `custom-theme-load-path' is the load path for themes. | ||
| 2521 | Emacs no longer looks for Custom themes in `load-path'. The default | ||
| 2522 | value of `custom-theme-load-path' says to look for themes in | ||
| 2523 | `custom-theme-directory', followed by a subdirectory of | ||
| 2524 | `data-directory' named "themes/", which contains a small selection of | ||
| 2525 | built-in Custom themes. | ||
| 2526 | |||
| 2527 | *** New option `custom-safe-themes' records known-safe theme files. | ||
| 2528 | If a theme is not in this list, Emacs queries before loading it, and | ||
| 2529 | offers to save the theme to `custom-safe-themes' automatically. By | ||
| 2530 | default, all themes included in Emacs are treated as safe. | ||
| 2531 | |||
| 2532 | ** Improved GTK integration | ||
| 2533 | |||
| 2534 | *** GTK scroll-bars are now placed on the right by default. | ||
| 2535 | The function `set-scroll-bar-mode' can change this. | ||
| 2536 | |||
| 2537 | *** GTK tool bars can have just text, just images or images and text. | ||
| 2538 | Customize `tool-bar-style' to choose the style. On a Gnome desktop, | ||
| 2539 | the default is taken from desktop settings. | ||
| 2540 | |||
| 2541 | *** GTK tool bars can be placed on any edge of the frame. | ||
| 2542 | The frame-parameter tool-bar-position controls this. It takes the | ||
| 2543 | values top, left, right or bottom. The Options => Show/Hide menu has | ||
| 2544 | entries for this. | ||
| 2545 | |||
| 2546 | *** The default colors for selected text (the `region' face) are taken | ||
| 2547 | from the GTK theme when Emacs is built with GTK. | ||
| 2548 | |||
| 2549 | *** Emacs uses GTK tooltips by default if built with GTK. | ||
| 2550 | You can disable this by changing `x-gtk-use-system-tooltips' to nil. | ||
| 2551 | |||
| 2552 | ** Graphical interface changes | ||
| 2553 | |||
| 2554 | *** On graphical displays, the mode-line no longer ends in dashes. | ||
| 2555 | Also, the first dash (which does not indicate anything) is just | ||
| 2556 | displayed as a space. | ||
| 2557 | |||
| 2558 | *** `menu-bar-select-buffer-function' lets you choose another operation | ||
| 2559 | instead of `switch-to-buffer' when selecting an item in the Buffers menu. | ||
| 2560 | |||
| 2561 | *** Lucid menus and dialogs can display antialiased fonts if Emacs is | ||
| 2562 | built with Xft. These fonts can be set via X resources, for example: | ||
| 2563 | Emacs.pane.menubar.font: Courier-12 | ||
| 2564 | |||
| 2565 | ** Exiting changes | ||
| 2566 | |||
| 2567 | *** Emacs now calls `kill-emacs' if it receives SIGTERM or SIGHUP, | ||
| 2568 | or if it receives a SIGINT signal in batch mode. | ||
| 2569 | |||
| 2570 | *** `kill-emacs-hook' is now also run in batch mode. | ||
| 2571 | Third-party code which adds to `kill-emacs-hook' should check if they | ||
| 2572 | do the right thing in batch mode. | ||
| 2573 | |||
| 2574 | ** Scrolling changes | ||
| 2575 | |||
| 2576 | *** New scrolling commands `scroll-up-command' and `scroll-down-command' | ||
| 2577 | (bound to C-v/[next] and M-v/[prior]) do not signal errors at top/bottom | ||
| 2578 | of buffer at first key-press (instead they move to top/bottom of buffer) | ||
| 2579 | when `scroll-error-top-bottom' is non-nil. | ||
| 2580 | |||
| 2581 | *** New option `scroll-error-top-bottom' (see above). | ||
| 2582 | |||
| 2583 | *** New scrolling commands `scroll-up-line' and `scroll-down-line' | ||
| 2584 | scroll a line instead of full screen. | ||
| 2585 | |||
| 2586 | *** New property `scroll-command' should be set on a command's symbol to | ||
| 2587 | define it as a scroll command affected by `scroll-preserve-screen-position'. | ||
| 2588 | |||
| 2589 | *** If you customize `scroll-conservatively' to a value greater than 100, | ||
| 2590 | Emacs will never recenter point in the window when it scrolls due to | ||
| 2591 | cursor motion commands or commands that move point (e.f., `M-g M-g'). | ||
| 2592 | Previously, you needed to use `most-positive-fixnum' as the value of | ||
| 2593 | `scroll-conservatively' to achieve the same effect. | ||
| 2594 | |||
| 2595 | *** "Aggressive" scrolling now honors the scroll margins. | ||
| 2596 | If you customize `scroll-up-aggressively' or | ||
| 2597 | `scroll-down-aggressively' and move point off the window, Emacs now | ||
| 2598 | scrolls the window so as to avoid positioning point inside the scroll | ||
| 2599 | margin. | ||
| 2600 | |||
| 2601 | ** Basic SELinux support has been added. | ||
| 2602 | This requires Emacs to be linked with libselinux at build time. | ||
| 2603 | |||
| 2604 | *** Emacs preserves the SELinux file context when backing up. | ||
| 2605 | Also, the function `copy-file' has an extra optional argument for | ||
| 2606 | preserving SELinux context, and the return value of `backup-buffer' | ||
| 2607 | now includes the SELinux context. | ||
| 2608 | |||
| 2609 | *** New functions `file-selinux-context' and `set-file-selinux-context' | ||
| 2610 | get and set the SELinux context of a file. | ||
| 2611 | |||
| 2612 | ** Trash changes | ||
| 2613 | |||
| 2614 | *** `delete-by-moving-to-trash' now only affects commands that specify | ||
| 2615 | trashing. This avoids inadvertently trashing temporary files. | ||
| 2616 | |||
| 2617 | *** Calling `delete-file' or `delete-directory' with a prefix argument | ||
| 2618 | now forces true deletion, regardless of `delete-by-moving-to-trash'. | ||
| 2619 | |||
| 2620 | ** File- and directory-local variable changes | ||
| 2621 | |||
| 2622 | *** You can stop directory local vars from applying to subdirectories. | ||
| 2623 | Add an element (subdirs . nil) to the alist portion of any variables | ||
| 2624 | settings to indicate that the section should not apply to | ||
| 2625 | subdirectories. | ||
| 2626 | |||
| 2627 | *** Directory local variables can apply to some file-less buffers. | ||
| 2628 | Affected modes include dired, vc-dir, and log-edit. For example, | ||
| 2629 | adding "(diff-mode . ((mode . whitespace)))" to .dir-locals.el will | ||
| 2630 | turn on `whitespace-mode' for *vc-diff* buffers. Modes should call | ||
| 2631 | `hack-dir-local-variables-non-file-buffer' to support this. | ||
| 2632 | |||
| 2633 | *** Using "mode: MINOR-MODE" to enable a minor mode is deprecated. | ||
| 2634 | Instead, use "eval: (minor-mode 1)". | ||
| 2635 | |||
| 2636 | *** The variable `inhibit-first-line-modes-regexps' has been renamed | ||
| 2637 | to `inhibit-local-variables-regexps'. As the name suggests, it now | ||
| 2638 | applies to ALL file local variables, not just -*- lines. The | ||
| 2639 | associated `inhibit-first-line-modes-suffixes' has been renamed in the | ||
| 2640 | corresponding way. | ||
| 2641 | |||
| 2642 | ** Window changes | ||
| 2643 | |||
| 2644 | *** The `quit-window' command now restores the last buffer displayed | ||
| 2645 | in the quitted window. | ||
| 2646 | |||
| 2647 | *** Resizing an Emacs frame now preserves proportional window sizes, | ||
| 2648 | modulo restrictions like window minimum sizes and fixed-size windows. | ||
| 2649 | |||
| 2650 | *** The behavior of `display-buffer' is now customizable in detail. | ||
| 2651 | |||
| 2652 | **** New option `display-buffer-base-action' specifies a list of | ||
| 2653 | user-determined display "actions" (functions and optional arguments | ||
| 2654 | for choosing the displaying window). | ||
| 2655 | |||
| 2656 | This takes precedence over the default display action, which is | ||
| 2657 | specified by `display-buffer-fallback-action'. | ||
| 2658 | |||
| 2659 | **** New option `display-buffer-alist' maps buffer name regexps to | ||
| 2660 | display actions, taking precedence over `display-buffer-base-action'. | ||
| 2661 | |||
| 2662 | *** New option `window-combination-limit'. | ||
| 2663 | The new option `window-combination-limit' allows to return the space | ||
| 2664 | obtained for resizing or creating a window more reliably to the window | ||
| 2665 | from which such space was obtained. | ||
| 2666 | |||
| 2667 | *** New option `window-combination-resize'. | ||
| 2668 | The new option `window-combination-resize' allows to split a window that | ||
| 2669 | otherwise cannot be split because it's too small by stealing space from | ||
| 2670 | other windows in the same combination. Subsequent resizing or deletion | ||
| 2671 | of the window will resize all windows in the same combination as well. | ||
| 2672 | |||
| 2673 | *** New option `frame-auto-hide-function' lets you choose between | ||
| 2674 | iconifying or deleting a frame when burying a buffer in a dedicated | ||
| 2675 | frame, or quitting a window showing a buffer in a frame of its own. | ||
| 2676 | |||
| 2677 | *** New commands `maximize-window' and `minimize-window'. | ||
| 2678 | These maximize and minimize the size of a window within its frame. | ||
| 2679 | |||
| 2680 | *** New commands `switch-to-prev-buffer' and `switch-to-next-buffer'. | ||
| 2681 | These functions allow to navigate through the live buffers that have | ||
| 2682 | been shown in a specific window. | ||
| 2683 | |||
| 2684 | ** Minibuffer changes | ||
| 2685 | |||
| 2686 | *** The inactive minibuffer has its own major mode `minibuffer-inactive-mode'. | ||
| 2687 | This is handy for minibuffer-only frames, and is also used for the feature | ||
| 2688 | where mouse-1 pops up *Messages*"', which can now easily be changed. | ||
| 2689 | |||
| 2690 | *** Minibuffers set `truncate-lines' to nil. | ||
| 2691 | If you want to change the value to something else, you could use | ||
| 2692 | for example `minibuffer-setup-hook'. | ||
| 2693 | |||
| 2694 | ** `auto-mode-case-fold' is now enabled by default. | ||
| 2695 | |||
| 2696 | ** `backup-by-copying-when-mismatch' now defaults to t. | ||
| 2697 | |||
| 2698 | ** New basic faces `error', `warning', `success'. | ||
| 2699 | These are used to highlight text indicating failure, caution or | ||
| 2700 | successful operation. | ||
| 2701 | |||
| 2702 | ** New option `list-colors-sort' defines the color sort order | ||
| 2703 | for `list-colors-display'. | ||
| 2704 | |||
| 2705 | ** The variable `focus-follows-mouse' now always defaults to nil. | ||
| 2706 | |||
| 2707 | |||
| 2708 | * Editing Changes in Emacs 24.1 | ||
| 2709 | |||
| 2710 | ** Search changes | ||
| 2711 | |||
| 2712 | *** C-y in Isearch is now bound to `isearch-yank-kill', instead of | ||
| 2713 | `isearch-yank-line'. | ||
| 2714 | |||
| 2715 | *** M-y in Isearch is now bound to `isearch-yank-pop', instead of | ||
| 2716 | `isearch-yank-kill'. | ||
| 2717 | |||
| 2718 | *** M-s C-e in Isearch is now bound to `isearch-yank-line'. | ||
| 2719 | |||
| 2720 | ** New commands `count-words-region' and `count-words'. | ||
| 2721 | |||
| 2722 | *** M-= is bound to `count-words-region', not `count-lines-region'. | ||
| 2723 | The `count-words-region' command, when called interactively, reports | ||
| 2724 | the number of lines, words, and characters in the region. It is a | ||
| 2725 | superset of the old `count-lines-region', which is now an obsolete | ||
| 2726 | alias for it. | ||
| 2727 | |||
| 2728 | ** The command `just-one-space' (M-SPC), if given a negative argument, | ||
| 2729 | also deletes newlines around point. | ||
| 2730 | |||
| 2731 | ** Deletion changes | ||
| 2732 | |||
| 2733 | *** New option `delete-active-region'. | ||
| 2734 | If non-nil, [delete] and DEL delete the region if it is active and no | ||
| 2735 | prefix argument is given. If set to `kill', those commands kill | ||
| 2736 | instead. | ||
| 2737 | |||
| 2738 | *** New command `delete-forward-char', bound to [delete]. | ||
| 2739 | This is meant for interactive use, and obeys `delete-active-region'. | ||
| 2740 | The command `delete-char' does not obey `delete-active-region'. | ||
| 2741 | |||
| 2742 | *** `delete-backward-char' is now a Lisp function. | ||
| 2743 | Apart from obeying `delete-active-region', its behavior is unchanged. | ||
| 2744 | However, the byte compiler now warns if it is called from Lisp; Lisp | ||
| 2745 | callers should use delete-char with a negative argument instead. | ||
| 2746 | |||
| 2747 | *** The option `mouse-region-delete-keys' has been deleted. | ||
| 2748 | |||
| 2749 | ** Selection changes. | ||
| 2750 | |||
| 2751 | The default handling of clipboard and primary selections has been | ||
| 2752 | changed to conform with modern X applications. In short, most | ||
| 2753 | commands for killing and yanking text now use the clipboard, while | ||
| 2754 | mouse commands use the primary selection. | ||
| 2755 | |||
| 2756 | In the following, we provide a list of these changes, followed by a | ||
| 2757 | list of steps to get the old behavior back if you prefer that. | ||
| 2758 | |||
| 2759 | *** `select-active-regions' now defaults to t. | ||
| 2760 | Merely selecting text (e.g. with drag-mouse-1) no longer puts it in | ||
| 2761 | the kill ring. The selected text is put in the primary selection, if | ||
| 2762 | the system possesses a separate primary selection facility (e.g. X). | ||
| 2763 | |||
| 2764 | **** `select-active-regions' also accepts a new value, `only'. | ||
| 2765 | This means to only set the primary selection for temporarily active | ||
| 2766 | regions (usually made by mouse-dragging or shift-selection); | ||
| 2767 | "ordinary" active regions, such as those made with C-SPC followed by | ||
| 2768 | point motion, do not alter the primary selection. | ||
| 2769 | |||
| 2770 | **** `mouse-drag-copy-region' now defaults to nil. | ||
| 2771 | |||
| 2772 | *** mouse-2 is now bound to `mouse-yank-primary'. | ||
| 2773 | This pastes from the primary selection, ignoring the kill-ring. | ||
| 2774 | Previously, mouse-2 was bound to `mouse-yank-at-click'. | ||
| 2775 | |||
| 2776 | *** `x-select-enable-clipboard' now defaults to t on all platforms. | ||
| 2777 | |||
| 2778 | *** `x-select-enable-primary' now defaults to nil. | ||
| 2779 | Thus, commands that kill text or copy it to the kill-ring (such as | ||
| 2780 | M-w, C-w, and C-k) also use the clipboard---not the primary selection. | ||
| 2781 | |||
| 2782 | **** The "Copy", "Cut", and "Paste" items in the "Edit" menu are now | ||
| 2783 | exactly equivalent to M-w, C-w, and C-y respectively. | ||
| 2784 | |||
| 2785 | **** Note that on MS-Windows, `x-select-enable-clipboard' was already | ||
| 2786 | non-nil by default, as Windows does not support the primary selection | ||
| 2787 | between applications. | ||
| 2788 | |||
| 2789 | *** To return to the previous behavior, do the following: | ||
| 2790 | |||
| 2791 | **** Change `select-active-regions' to nil. | ||
| 2792 | **** Change `mouse-drag-copy-region' to t. | ||
| 2793 | **** Change `x-select-enable-primary' to t (on X only). | ||
| 2794 | **** Change `x-select-enable-clipboard' to nil. | ||
| 2795 | **** Bind `mouse-yank-at-click' to mouse-2. | ||
| 2796 | |||
| 2797 | *** Support for X cut buffers has been removed. | ||
| 2798 | |||
| 2799 | *** X clipboard managers are now supported. | ||
| 2800 | To inhibit this, change `x-select-enable-clipboard-manager' to nil. | ||
| 2801 | |||
| 2802 | ** New command `C-x r N' (`rectangle-number-lines') numbers the lines | ||
| 2803 | in the current rectangle. With a prefix argument, this prompts for a | ||
| 2804 | number to count from and for a format string. | ||
| 2805 | |||
| 2806 | ** `redisplay-dont-pause' now defaults to t. | ||
| 2807 | This makes Emacs feel more responsive to editing commands that arrive | ||
| 2808 | at high rate, e.g. if you lean on some key, because stopping redisplay | ||
| 2809 | in the middle (when this variable is nil) forces more expensive | ||
| 2810 | updates later on, and Emacs appears to be unable to keep up. | ||
| 2811 | |||
| 2812 | ** The behavior of <TAB> for active regions in Text mode has changed. | ||
| 2813 | In Text and related modes, typing <TAB> (`indent-for-tab-command') | ||
| 2814 | when the region is active causes Emacs to indent all the lines in the | ||
| 2815 | region, aligning them with the line previous to the first line in the | ||
| 2816 | region (or with the left margin if there is no previous line). | ||
| 2817 | |||
| 2818 | ** When `occur' is called with a prefix argument, matching strings are | ||
| 2819 | collected into the `*Occur*' buffer without line numbers. If there | ||
| 2820 | are parenthesized subexpressions in the specified regexp, `occur' | ||
| 2821 | reads replacement text that may contain \\& and \\N whose convention | ||
| 2822 | follows `replace-match'. | ||
| 2823 | |||
| 2824 | |||
| 2825 | * Changes in Specialized Modes and Packages in Emacs 24.1 | ||
| 2826 | |||
| 2827 | ** Archive Mode has basic support for browsing and updating 7z archives. | ||
| 2828 | |||
| 2829 | ** BibTeX mode | ||
| 2830 | |||
| 2831 | *** BibTeX mode now supports biblatex. | ||
| 2832 | Use the variable `bibtex-dialect' to select different BibTeX dialects. | ||
| 2833 | `bibtex-entry-field-alist' is now an obsolete alias for | ||
| 2834 | `bibtex-BibTeX-entry-alist'. | ||
| 2835 | |||
| 2836 | *** New command `bibtex-search-entries', bound to C-c C-a. | ||
| 2837 | |||
| 2838 | *** New `bibtex-entry-format' option `sort-fields', disabled by default. | ||
| 2839 | |||
| 2840 | *** New variable `bibtex-search-entry-globally'. | ||
| 2841 | |||
| 2842 | ** Browse-url | ||
| 2843 | |||
| 2844 | *** New option `browse-url-mailto-function' specifies how to handle "mailto:"s. | ||
| 2845 | |||
| 2846 | *** The default browser used by the package is now the "xdg-open" program, | ||
| 2847 | on platforms that support it. This calls your desktop's preferred browser. | ||
| 2848 | |||
| 2849 | ** Calc | ||
| 2850 | |||
| 2851 | *** Support for musical notes. | ||
| 2852 | |||
| 2853 | *** Support for logarithmic units. | ||
| 2854 | |||
| 2855 | *** No longer uses the tex prefix for TeX specific unit names when | ||
| 2856 | using TeX or LaTeX mode. | ||
| 2857 | |||
| 2858 | *** New option to highlight selections using faces. | ||
| 2859 | |||
| 2860 | *** `calc-histogram' has the option of using a vector to determine the bins. | ||
| 2861 | |||
| 2862 | *** New "O" option prefix. | ||
| 2863 | |||
| 2864 | *** Use the "O" prefix to "d r" (`calc-radix') to turn on twos-complement mode. | ||
| 2865 | |||
| 2866 | ** Calendar, Diary, and Appt | ||
| 2867 | |||
| 2868 | *** Diary entries can contain non-printing "comments". | ||
| 2869 | See the variable `diary-comment-start'. | ||
| 2870 | |||
| 2871 | *** Appointments can specify their individual warning times. | ||
| 2872 | See the variable `appt-warning-time-regexp'. | ||
| 2873 | |||
| 2874 | *** The function specified by `appt-disp-window-function' may be passed | ||
| 2875 | lists of arguments if multiple appointments are due at similar times. | ||
| 2876 | If you are using a custom function for this, you should update it. | ||
| 2877 | |||
| 2878 | *** New function `diary-hebrew-birthday'. | ||
| 2879 | |||
| 2880 | *** Elements of `calendar-day-abbrev-array' and `calendar-month-abbrev-array' | ||
| 2881 | may no longer be nil, but must all be strings. | ||
| 2882 | |||
| 2883 | *** The obsolete (since Emacs 22.1) method of enabling the appt | ||
| 2884 | package by adding `appt-make-list' to `diary-hook' has been removed. | ||
| 2885 | Use `appt-activate' instead. | ||
| 2886 | |||
| 2887 | *** Some appt variables (obsolete since Emacs 22.1) have been removed: | ||
| 2888 | appt-issue-message (use the function appt-activate) | ||
| 2889 | appt-visible/appt-msg-window (use the variable appt-display-format) | ||
| 2890 | |||
| 2891 | *** Some diary function aliases (obsolete since Emacs 22.1) have been removed: | ||
| 2892 | view-diary-entries, list-diary-entries, show-all-diary-entries | ||
| 2893 | |||
| 2894 | ** CC Mode | ||
| 2895 | |||
| 2896 | *** New feature to "guess" the style in an existing buffer. | ||
| 2897 | The main entry point is M-x c-guess. | ||
| 2898 | |||
| 2899 | *** Java Mode now supports Java 5.0 (Tiger) and 6 (Mustang). | ||
| 2900 | |||
| 2901 | *** `c-beginning-of-defun' and `c-end-of-defun' now respect nested scopes. | ||
| 2902 | Thus C-M-a will, by default, go to the beginning of the immediate function, | ||
| 2903 | not the top level. | ||
| 2904 | |||
| 2905 | *** "Macros with semicolons" can be registered for correct indentation. | ||
| 2906 | Where such a macro ends a line (no semicolon) the next statement is no longer | ||
| 2907 | parsed as a statement continuation. | ||
| 2908 | |||
| 2909 | ** Comint and modes derived from it use the standard completion code. | ||
| 2910 | |||
| 2911 | ** Compilation mode | ||
| 2912 | |||
| 2913 | *** Compilation mode can be used without Font Lock mode. | ||
| 2914 | `compilation-parse-errors-function' is now obsolete. | ||
| 2915 | |||
| 2916 | *** New variable `compilation-filter-start', which is bound while | ||
| 2917 | `compilation-filter-hook' runs. It records the start position of the | ||
| 2918 | text inserted by `compilation-filter'. | ||
| 2919 | |||
| 2920 | *** `compilation-error-screen-columns' and `compilation-first-column' | ||
| 2921 | are obeyed in the editing buffer. So programming language modes can | ||
| 2922 | set them, whereas previously only the value in the *Compilation* | ||
| 2923 | buffer was used. | ||
| 2924 | |||
| 2925 | ** Customize | ||
| 2926 | |||
| 2927 | *** Customize buffers now contain a search field. | ||
| 2928 | The search is performed using `customize-apropos'. | ||
| 2929 | To turn off the search field, set `custom-search-field' to nil. | ||
| 2930 | |||
| 2931 | *** Options in customize group buffers start out hidden if not customized. | ||
| 2932 | Use the arrow to the left of the option name to toggle visibility. | ||
| 2933 | |||
| 2934 | *** custom-buffer-sort-alphabetically now defaults to t. | ||
| 2935 | |||
| 2936 | *** The color widget now has a "Choose" button, which allows you to | ||
| 2937 | choose a color via `list-colors-display'. | ||
| 2938 | |||
| 2939 | ** D-Bus | ||
| 2940 | |||
| 2941 | *** It is now possible to access buses other than the default system | ||
| 2942 | or session bus. | ||
| 2943 | |||
| 2944 | *** The `dbus-register-method' and `dbus-register-property' functions | ||
| 2945 | optionally do not register names. | ||
| 2946 | |||
| 2947 | *** The new function `dbus-register-service' registers a known service | ||
| 2948 | name on a D-Bus without also registering a property or a method. | ||
| 2949 | |||
| 2950 | ** Dired-x | ||
| 2951 | |||
| 2952 | *** C-x C-j (`dired-jump') and C-x 4 C-j (`dired-jump-other-window'), | ||
| 2953 | if called with a prefix argument, read a file name from the minibuffer | ||
| 2954 | instead of using the current buffer. | ||
| 2955 | |||
| 2956 | *** The "dired local variables" feature of Dired-x is obsolete. | ||
| 2957 | The standard directory local variables feature replaces it. | ||
| 2958 | |||
| 2959 | ** ERC changes | ||
| 2960 | |||
| 2961 | *** New options `erc-autojoin-timing' and `erc-autojoin-delay', | ||
| 2962 | controlling attempts to autojoin a channel. | ||
| 2963 | |||
| 2964 | *** New variable `erc-coding-system-precedence': If we use `undecided' | ||
| 2965 | as the server coding system, this variable will then be consulted. | ||
| 2966 | The default is to decode strings that can be decoded as utf-8 as | ||
| 2967 | utf-8, and do the normal `undecided' decoding for the rest. | ||
| 2968 | |||
| 2969 | ** Eshell changes | ||
| 2970 | |||
| 2971 | *** The default value of `eshell-directory-name' has changed | ||
| 2972 | to be an "eshell" directory in `user-emacs-directory'. | ||
| 2973 | The old "~/.eshell/" directory is still used if it exists, though. | ||
| 2974 | |||
| 2975 | ** gdb-mi | ||
| 2976 | |||
| 2977 | *** The M-x gdb command now uses the GDB Machine Interface protocol. | ||
| 2978 | It now supports multithread non-stop debugging and simultaneous | ||
| 2979 | debugging of several threads. | ||
| 2980 | |||
| 2981 | ** Image mode | ||
| 2982 | |||
| 2983 | *** RET (`image-toggle-animation') toggles animation, if applicable. | ||
| 2984 | Animation plays once, unless the option `image-animate-loop' is non-nil. | ||
| 2985 | |||
| 2986 | ** Info | ||
| 2987 | |||
| 2988 | *** New command M-x info-display-manual displays a named Info manual. | ||
| 2989 | If that manual is already visited in some Info buffer, it displays | ||
| 2990 | that buffer. (This is handy if you have many manuals in many *info* | ||
| 2991 | buffers, and don't remember the name of the buffer visiting the manual | ||
| 2992 | you want to consult.) Otherwise, it loads and displays the manual. | ||
| 2993 | |||
| 2994 | *** `e' is now bound to `end-of-buffer' rather than to `Info-edit'. | ||
| 2995 | This is for compatibility with the stand-alone Info reader program, | ||
| 2996 | and also because `Info-edit' is a rarely used command that is disabled | ||
| 2997 | by default. | ||
| 2998 | |||
| 2999 | ** Mail mode changes (not Message mode) | ||
| 3000 | |||
| 3001 | *** New command M-x mail-add-attachment for adding MIME attachments | ||
| 3002 | |||
| 3003 | *** The command M-x mail-attach-file was renamed to M-x mail-insert-file. | ||
| 3004 | (Its name is misleading, since it has nothing to do with MIME | ||
| 3005 | attachments.) The old name is now an obsolete alias to the new name. | ||
| 3006 | |||
| 3007 | ** MH-E has been updated to MH-E version 8.3.1. | ||
| 3008 | See MH-E-NEWS for details. | ||
| 3009 | |||
| 3010 | ** Modula-2 mode provides auto-indentation. | ||
| 3011 | |||
| 3012 | ** mpc.el: Can use pseudo tags of the form tag1|tag2 as a union of two tags. | ||
| 3013 | |||
| 3014 | ** nXML mode no longer binds C-RET to `nxml-complete'. | ||
| 3015 | Completion is now performed via `completion-at-point', bound to C-M-i | ||
| 3016 | or M-TAB. If `nxml-bind-meta-tab-to-complete-flag' is non-nil (the | ||
| 3017 | default), this performs tag completion. | ||
| 3018 | |||
| 3019 | ** Org mode has been updated to version 7.8.09. | ||
| 3020 | See ORG-NEWS for details. | ||
| 3021 | |||
| 3022 | ** Prolog mode has been completely revamped, with lots of additional | ||
| 3023 | functionality such as more intelligent indentation, electricity, | ||
| 3024 | support for more variants, including Mercury, and a lot more. | ||
| 3025 | |||
| 3026 | ** Rmail | ||
| 3027 | |||
| 3028 | *** The command `rmail-epa-decrypt' decrypts OpenPGP data | ||
| 3029 | in the Rmail incoming message. | ||
| 3030 | |||
| 3031 | *** The variable `rmail-message-filter' no longer has any effect. | ||
| 3032 | This change was made in Emacs 23.1 but was not advertised at the time. | ||
| 3033 | Try using `rmail-show-message-hook' instead. | ||
| 3034 | |||
| 3035 | ** Shell mode | ||
| 3036 | |||
| 3037 | *** M-x shell prompts for the shell path name if the default directory | ||
| 3038 | is a remote file name and neither the environment variable $ESHELL nor | ||
| 3039 | the variable `explicit-shell-file-name' is set. | ||
| 3040 | |||
| 3041 | *** TAB is now bound to the standard `completion-at-point' command, | ||
| 3042 | which now implements the pcomplete rules for shell command completion. | ||
| 3043 | |||
| 3044 | ** SMTPmail | ||
| 3045 | |||
| 3046 | *** SMTPmail now uses encrypted connections (via STARTTLS) by default | ||
| 3047 | if the mail server supports them. This uses either built-in GnuTLS | ||
| 3048 | support, or the starttls.el library. Customize `smtpmail-stream-type' | ||
| 3049 | to change this. | ||
| 3050 | |||
| 3051 | *** The variable `smtpmail-auth-credentials' has been removed. | ||
| 3052 | By default, the information is now stored in the file ~/.authinfo. | ||
| 3053 | This was the default value of smtpmail-auth-credentials. If you had | ||
| 3054 | customized smtpmail-auth-credentials to a list of user names and | ||
| 3055 | passwords, those settings are not used. During your first connection | ||
| 3056 | to the smtp server, Emacs will prompt for the user name and password, | ||
| 3057 | and offer to save them to ~/.authinfo. Or you can manually copy the | ||
| 3058 | credentials to ~/.authinfo. For example, if you had | ||
| 3059 | |||
| 3060 | (setq smtpmail-auth-credentials | ||
| 3061 | '(("mail.example.org" 25 "jim" "s!cret"))) | ||
| 3062 | |||
| 3063 | then the equivalent line in ~/.authinfo would be | ||
| 3064 | |||
| 3065 | machine mail.example.org port 25 login jim password s!cret | ||
| 3066 | |||
| 3067 | See the auth-source manual for more information, e.g. on encrypting | ||
| 3068 | the credentials file. | ||
| 3069 | |||
| 3070 | *** The variable `smtpmail-starttls-credentials' has been removed. | ||
| 3071 | If you had that set, you need to put | ||
| 3072 | |||
| 3073 | machine smtp.whatever.foo port 25 key "~/.my_smtp_tls.key" cert "~/.my_smtp_tls.cert" | ||
| 3074 | |||
| 3075 | in your ~/.authinfo file instead. | ||
| 3076 | |||
| 3077 | *** SMTPmail defaults to using the address in the From: header as the | ||
| 3078 | SMTP MAIL FROM envelope. To override this, set `mail-envelope-from' | ||
| 3079 | to the address you wish to use instead. | ||
| 3080 | |||
| 3081 | ** SQL mode | ||
| 3082 | |||
| 3083 | *** New options `sql-port', `sql-connection-alist', `sql-send-terminator', | ||
| 3084 | and `sql-oracle-scan-on'. | ||
| 3085 | |||
| 3086 | *** New options controlling prompting for login parameters. | ||
| 3087 | Each supported product has a custom variable `sql-*-login-params', | ||
| 3088 | which is a list of the parameters to be prompted for before a | ||
| 3089 | connection is established. | ||
| 3090 | |||
| 3091 | *** The command `sql-product-interactive' now takes a prefix argument, | ||
| 3092 | which causes it to prompt for an SQL product. | ||
| 3093 | |||
| 3094 | *** Product-specific SQL interactive commands now take prefix arguments. | ||
| 3095 | These commands (`sql-sqlite', `sql-postgres', `sql-mysql', etc.), | ||
| 3096 | given a prefix argument, prompt for a name for the SQL interactive | ||
| 3097 | buffer. This reduces the need for calling `sql-rename-buffer'. | ||
| 3098 | |||
| 3099 | *** SQL interactive modes suppress command continuation prompts, and | ||
| 3100 | replace tabs with spaces. The first change impacts multiple line SQL | ||
| 3101 | statements entered with C-j between each line, statements yanked into | ||
| 3102 | the buffer and statements sent with `sql-send-*' functions. The | ||
| 3103 | second prevents the MySQL and Postgres interpreters from listing | ||
| 3104 | object name completions when sent text via `sql-send-*' functions. | ||
| 3105 | |||
| 3106 | *** New command `sql-connect' starts a predefined SQLi session, | ||
| 3107 | using the login parameters from `sql-connection-alist'. | ||
| 3108 | |||
| 3109 | *** New "Save Connection" menu item in SQLi buffers. | ||
| 3110 | This gathers the login params specified for the SQLi session, if it | ||
| 3111 | was not started by a connection, and saves them as a new connection. | ||
| 3112 | |||
| 3113 | *** New commands for listing database objects and details: | ||
| 3114 | sql-list-all and sql-list-table. | ||
| 3115 | |||
| 3116 | *** An API for manipulating SQL product definitions has been added. | ||
| 3117 | |||
| 3118 | ** TeX modes | ||
| 3119 | |||
| 3120 | *** latex-electric-env-pair-mode keeps \begin..\end matched on the fly. | ||
| 3121 | |||
| 3122 | ** Tramp | ||
| 3123 | |||
| 3124 | *** New inline access method "ksu" (kerberized su). | ||
| 3125 | |||
| 3126 | *** The following access methods are discontinued: "ssh1_old", | ||
| 3127 | "ssh2_old", "scp1_old", "scp2_old", "imap", "imaps" and "fish". | ||
| 3128 | |||
| 3129 | *** The user option `remote-file-name-inhibit-cache' controls whether | ||
| 3130 | remote file attributes are cached for better performance. | ||
| 3131 | |||
| 3132 | *** The option `ange-ftp-binary-file-name-regexp' has changed its | ||
| 3133 | default value to "". | ||
| 3134 | |||
| 3135 | *** Handlers for `file-selinux-context' and `set-file-selinux-context' | ||
| 3136 | for remote machines which support SELinux. | ||
| 3137 | |||
| 3138 | ** New function `url-queue-retrieve', which behaves like url-retrieve, | ||
| 3139 | but with limits (`url-queue-parallel-processes', `url-queue-timeout') on | ||
| 3140 | the degree of parallelism. | ||
| 3141 | |||
| 3142 | ** VC and related modes | ||
| 3143 | |||
| 3144 | *** Support for pulling on distributed version control systems. | ||
| 3145 | The command C-x v + (`vc-pull') runs a "pull" operation, if it is | ||
| 3146 | supported (currently with Bzr, Git, and Mercurial), to update the | ||
| 3147 | current branch and working tree. A prefix argument means to prompt | ||
| 3148 | the user for specifics, e.g. a pull location. | ||
| 3149 | |||
| 3150 | *** `vc-update' is now an alias for `vc-pull'. | ||
| 3151 | |||
| 3152 | *** Support for merging on distributed version control systems. | ||
| 3153 | The command C-x v m (`vc-merge') now runs a "merge" operation, if it | ||
| 3154 | is supported (currently with Bzr, Git, and Mercurial), to merge | ||
| 3155 | changes from another branch into the current one. It prompts for | ||
| 3156 | specifics, e.g. a merge source. | ||
| 3157 | |||
| 3158 | *** New option `vc-revert-show-diff' controls whether `vc-revert' | ||
| 3159 | shows a diff while querying the user. It defaults to t. | ||
| 3160 | |||
| 3161 | *** Log entries in some Log View buffers can be toggled to display a | ||
| 3162 | longer description by typing RET (log-view-toggle-entry-display). | ||
| 3163 | This is currently supported for Bzr, Git, and Mercurial (to support | ||
| 3164 | another backend, define a `log-view-expanded-log-entry-function'). | ||
| 3165 | In the Log View buffers made by C-x v L (`vc-print-root-log'), you can | ||
| 3166 | use this to display the full log entry for the revision at point. | ||
| 3167 | |||
| 3168 | *** New command `vc-ediff' allows visual comparison of two revisions | ||
| 3169 | of a file similar to `vc-diff', but using ediff backend. | ||
| 3170 | |||
| 3171 | *** The option `vc-initial-comment' was removed in Emacs 23.2, but | ||
| 3172 | this was not advertised at the time. | ||
| 3173 | |||
| 3174 | *** `vc-toggle-read-only' is an obsolete alias for `toggle-read-only'. | ||
| 3175 | Since Emacs 23, it has done the same thing as `toggle-read-only', but | ||
| 3176 | this was not advertised at the time. | ||
| 3177 | |||
| 3178 | ** Obsolete modes | ||
| 3179 | |||
| 3180 | *** abbrevlist.el | ||
| 3181 | |||
| 3182 | *** erc-hecomplete.el (use erc-pcomplete.el instead) | ||
| 3183 | |||
| 3184 | *** partial-completion-mode (complete.el) is obsolete. | ||
| 3185 | You can get a comparable behavior with: | ||
| 3186 | (setq completion-styles '(partial-completion initials)) | ||
| 3187 | (setq completion-pcm-complete-word-inserts-delimiters t) | ||
| 3188 | |||
| 3189 | *** pc-mode.el is obsolete (CUA mode is much more comprehensive). | ||
| 3190 | |||
| 3191 | *** pgg is obsolete (use EasyPG instead). | ||
| 3192 | |||
| 3193 | *** sregex.el is obsolete, since rx.el is a strict superset. | ||
| 3194 | |||
| 3195 | *** s-region.el and pc-select.el are obsolete. | ||
| 3196 | They are superseded by shift-select-mode, enabled by default since 23.1. | ||
| 3197 | |||
| 3198 | *** vc-mcvs.el is obsolete (for lack of a maintainer). | ||
| 3199 | |||
| 3200 | ** Miscellaneous | ||
| 3201 | |||
| 3202 | *** The Landmark game is now invoked with `landmark', not `lm'. | ||
| 3203 | Its functions and variables have been similarly renamed. | ||
| 3204 | |||
| 3205 | *** In `ido-file-completion-map', C-v is no longer bound to `ido-toggle-vc'. | ||
| 3206 | (This interfered with cua-mode.) | ||
| 3207 | |||
| 3208 | *** f90.el has some support for Fortran 2008 syntax. | ||
| 3209 | |||
| 3210 | *** `copyright-fix-years' can optionally convert consecutive years to ranges. | ||
| 3211 | |||
| 3212 | *** New command `nato-region' converts text to NATO phonetic alphabet. | ||
| 3213 | |||
| 3214 | |||
| 3215 | * New Modes and Packages in Emacs 24.1 | ||
| 3216 | |||
| 3217 | ** Occur Edit mode applies edits made in *Occur* buffers to the | ||
| 3218 | original buffers. It is bound to "e" in Occur mode. | ||
| 3219 | |||
| 3220 | ** New global minor mode electric-pair-mode. | ||
| 3221 | When enabled, typing an open parenthesis automatically inserts the | ||
| 3222 | matching closing one. | ||
| 3223 | |||
| 3224 | ** New global minor mode electric-indent-mode. | ||
| 3225 | When enabled, typing certain characters triggers reindentation. | ||
| 3226 | Major modes wishing to use this can set electric-indent-chars or | ||
| 3227 | electric-indent-functions. | ||
| 3228 | |||
| 3229 | ** New global minor mode electric-layout-mode. | ||
| 3230 | When enabled, typing certain characters automatically inserts newlines. | ||
| 3231 | Major modes wishing to use this can set electric-layout-rules. | ||
| 3232 | |||
| 3233 | ** tabulated-list.el provides a generic major mode for tabulated data, | ||
| 3234 | from which other modes can be derived. | ||
| 3235 | |||
| 3236 | ** pcase.el provides the ML-style pattern matching macro `pcase'. | ||
| 3237 | |||
| 3238 | ** secrets.el is an implementation of the Secret Service API, an | ||
| 3239 | interface to password managers like GNOME Keyring or KDE Wallet. The | ||
| 3240 | Secret Service API requires D-Bus for communication. The command | ||
| 3241 | `secrets-show-secrets' offers a buffer with a visualization of the | ||
| 3242 | secrets. | ||
| 3243 | |||
| 3244 | ** notifications.el provides an implementation of the Desktop | ||
| 3245 | Notifications API. It requires D-Bus for communication. | ||
| 3246 | |||
| 3247 | ** soap-client.el supports access to SOAP web services from Emacs. | ||
| 3248 | soap-inspect.el is an interactive inspector for SOAP WSDL structures. | ||
| 3249 | |||
| 3250 | ** New generic mode, xmodmap-generic-mode, for xmodmap files. | ||
| 3251 | |||
| 3252 | ** New emacs-lock.el package. | ||
| 3253 | The previous version has been moved to obsolete/old-emacs-lock.el. | ||
| 3254 | Now, there is a proper minor mode `emacs-lock-mode'. Protection | ||
| 3255 | against exiting Emacs and killing the buffer can be set separately. | ||
| 3256 | The mechanism for automatically turning off protection for buffers | ||
| 3257 | with dead inferior processes has been generalized. | ||
| 3258 | |||
| 3259 | |||
| 3260 | * Incompatible Lisp Changes in Emacs 24.1 | ||
| 3261 | |||
| 3262 | ** Passing a nil argument to a minor mode function call now ENABLES | ||
| 3263 | the minor mode unconditionally. This is so that you can write e.g. | ||
| 3264 | |||
| 3265 | (add-hook 'text-mode-hook 'foo-mode) | ||
| 3266 | |||
| 3267 | to enable foo-mode in Text mode buffers, removing the need for | ||
| 3268 | `turn-on-foo-mode' style functions. This affects all mode commands | ||
| 3269 | defined by `define-minor-mode'. If called interactively, the mode | ||
| 3270 | command still toggles the minor mode. | ||
| 3271 | |||
| 3272 | ** The return value of `backup-buffer' has changed. | ||
| 3273 | It is now a list of three elements, where the second element is a list | ||
| 3274 | describing the original file's SELinux context. If Emacs or the | ||
| 3275 | system lacks SELinux support, the context list is (nil nil nil nil). | ||
| 3276 | See "Basic SELinux support" above, under "Changes in Emacs 24.1". | ||
| 3277 | |||
| 3278 | ** `char-direction-table' and the `char-direction' function were deleted. | ||
| 3279 | They were buggy and inferior to the new support of bidirectional | ||
| 3280 | editing introduced in Emacs 24. If you need the bidirectional | ||
| 3281 | properties of a character, use `get-char-code-property' with the last | ||
| 3282 | argument `bidi-class'. | ||
| 3283 | |||
| 3284 | ** `copy-directory' now copies the source directory as a subdirectory | ||
| 3285 | of the target directory, if the latter is an existing directory. The | ||
| 3286 | new optional arg COPY-CONTENTS, if non-nil, makes the function copy | ||
| 3287 | the contents directly into a pre-existing target directory. | ||
| 3288 | |||
| 3289 | ** For mouse click input events in the text area, the Y pixel | ||
| 3290 | coordinate in the POSITION list now counts from the top of the text | ||
| 3291 | area, excluding any header line. Previously, it counted from the top | ||
| 3292 | of the header line. | ||
| 3293 | |||
| 3294 | ** Support for "old-style" backquotes, obsolete for 10+ years, has | ||
| 3295 | been further reduced. Now a backquote not followed by a space is | ||
| 3296 | always treated as a "new-style" backquote. Please remove all | ||
| 3297 | "old-style" backquotes from your code. If your code uses backquotes | ||
| 3298 | as documented in the Elisp manual, and compiles without warning, then | ||
| 3299 | you have nothing to do in this regard. Code not following the | ||
| 3300 | appropriate conventions may fail to compile. | ||
| 3301 | |||
| 3302 | The most common cause of trouble seems to be an old-style backquote | ||
| 3303 | followed by a newline. Another cause of trouble is vector notation | ||
| 3304 | for key sequence notation: instead of [(control ,)] and [(control ')], | ||
| 3305 | you should write [(control ?,)] and [(control ?')], which will work in | ||
| 3306 | older Emacsen too. | ||
| 3307 | |||
| 3308 | ** The macro `eval-at-startup' was removed in Emacs 23.2, but this | ||
| 3309 | was not advertised at the time. The function `custom-initialize-delay' | ||
| 3310 | replaced all known uses. | ||
| 3311 | |||
| 3312 | ** `view-buffer' now treats special mode-class in the same way that | ||
| 3313 | `view-file' has since Emacs 22 (i.e. it won't enable View mode if the | ||
| 3314 | major mode is special). | ||
| 3315 | |||
| 3316 | ** Menu and tool bar changes | ||
| 3317 | |||
| 3318 | *** During startup, Emacs no longer adds entries for `menu-bar-lines' | ||
| 3319 | and `tool-bar-lines' to `default-frame-alist' and `initial-frame-alist'. | ||
| 3320 | With these alist entries omitted, `make-frame' checks the value of the | ||
| 3321 | variable `menu-bar-mode'/`tool-bar-mode' to determine whether to create | ||
| 3322 | a menu-bar or tool-bar, respectively. If the alist entries are added, | ||
| 3323 | they override the value of `menu-bar-mode'/`tool-bar-mode'. | ||
| 3324 | |||
| 3325 | *** The menu bar bindings's caches are not used any more. | ||
| 3326 | Use (where-is-internal <def> nil t) instead. | ||
| 3327 | |||
| 3328 | ** Regions created by mouse dragging are now normal active regions, | ||
| 3329 | similar to those created by shift-selection (see Selection changes | ||
| 3330 | above). In previous Emacs versions, these regions were delineated by | ||
| 3331 | `mouse-drag-overlay'; that variable has been removed. | ||
| 3332 | |||
| 3333 | ** The fourth argument of `filter-buffer-substring' has been removed. | ||
| 3334 | If you want to remove text properties from the final result, simply | ||
| 3335 | pass the result through substring-no-properties. | ||
| 3336 | |||
| 3337 | ** cl.el no longer provides `cl-19'. | ||
| 3338 | |||
| 3339 | ** The following obsolete functions and aliases have been removed | ||
| 3340 | (the appropriate new function is given in parentheses; "not needed" | ||
| 3341 | means you can just remove all calls to the function in question): | ||
| 3342 | |||
| 3343 | *** `comint-kill-output' (`comint-delete-output') | ||
| 3344 | *** `decompose-composite-char' (`char-to-string') | ||
| 3345 | *** `outline-visible' (`outline-invisible-p') | ||
| 3346 | *** `internal-find-face' (`facep') | ||
| 3347 | *** `internal-get-face' (`facep and check-face') | ||
| 3348 | *** `frame-update-faces' (not needed) | ||
| 3349 | *** `frame-update-face-colors' (`frame-set-background-mode') | ||
| 3350 | *** `x-frob-font-weight' and `x-frob-font-slant' (`make-face-*' functions) | ||
| 3351 | *** `x-make-font-bold' and `x-make-font-demibold' (`make-face-bold') | ||
| 3352 | *** `x-make-font-italic' and `x-make-font-oblique' (`make-face-italic') | ||
| 3353 | *** `x-make-font-bold-italic' (`make-face-bold-italic') | ||
| 3354 | *** `x-make-font-unbold' (`make-face-unbold') | ||
| 3355 | *** `x-make-font-unitalic' (`make-face-unitalic') | ||
| 3356 | *** `mldrag-drag-mode-line' (`mouse-drag-mode-line') | ||
| 3357 | *** `mldrag-drag-vertical-line' (`mouse-drag-vertical-line') | ||
| 3358 | *** `iswitchb-default-keybindings' (`iswitchb-mode') | ||
| 3359 | *** `char-bytes' (== 1) | ||
| 3360 | *** `isearch-return-char' (`isearch-printing-char') | ||
| 3361 | *** `make-local-hook' (not needed) | ||
| 3362 | *** `set-screen-height' (`set-frame-height') | ||
| 3363 | *** `set-screen-width' (`set-frame-width') | ||
| 3364 | |||
| 3365 | ** The following obsolete variables and varaliases have been removed | ||
| 3366 | (the appropriate new variable is given in parentheses): | ||
| 3367 | |||
| 3368 | *** `checkdoc-minor-keymap' (`checkdoc-minor-mode-map') | ||
| 3369 | *** `vc-header-alist' (`vc-BACKEND-header') | ||
| 3370 | *** `directory-sep-char' (== ?/) | ||
| 3371 | *** `font-lock-defaults-alist' (`font-lock-defaults') | ||
| 3372 | *** `e' (`float-e'). | ||
| 3373 | |||
| 3374 | ** The following obsolete files were removed: | ||
| 3375 | sc.el, x-menu.el, rnews.el, rnewspost.el | ||
| 3376 | |||
| 3377 | ** The format of the finder-inf.el file has changed, since the Finder | ||
| 3378 | mechanism is now based on the package system. The variable | ||
| 3379 | `finder-package-info' is replaced by `package--builtins' and | ||
| 3380 | `finder-keywords-hash'. | ||
| 3381 | |||
| 3382 | ** When generating autoloads, `update-directory-autoloads' no longer | ||
| 3383 | assumes every inspected file is in your `load-path'. It instead | ||
| 3384 | generates relative names according to the current `load-path'. | ||
| 3385 | |||
| 3386 | |||
| 3387 | * Lisp Changes in Emacs 24.1 | ||
| 3388 | |||
| 3389 | ** Code can now use lexical scoping by default instead of dynamic scoping. | ||
| 3390 | The `lexical-binding' variable enables lexical scoping for local | ||
| 3391 | variables. It is typically set via a file-local variable in the first | ||
| 3392 | line of the file, in which case it applies to all the code in that | ||
| 3393 | file. | ||
| 3394 | |||
| 3395 | *** `eval' takes a new optional argument `lexical' to choose the new lexical | ||
| 3396 | binding instead of the old dynamic binding mode. | ||
| 3397 | |||
| 3398 | *** Lexically scoped interpreted functions are represented with a new form | ||
| 3399 | of function value which looks like (closure ENV ARGS &rest BODY). | ||
| 3400 | |||
| 3401 | *** New macro `letrec' to define recursive local functions. | ||
| 3402 | |||
| 3403 | *** `defvar' and `defconst' now mark the variable as special (dynamic). | ||
| 3404 | So do `defcustom' and other forms that call `defvar' as a subroutine. | ||
| 3405 | |||
| 3406 | *** New function `special-variable-p' to check whether a variable is | ||
| 3407 | declared as dynamically bound. | ||
| 3408 | |||
| 3409 | *** The form ((lambda ...) ...) is deprecated. | ||
| 3410 | |||
| 3411 | ** An Emacs Lisp testing tool is now included. | ||
| 3412 | Emacs Lisp developers can use this tool to write automated tests for | ||
| 3413 | their code. See the ERT info manual for details. | ||
| 3414 | |||
| 3415 | ** Changes for bidirectional display and editing | ||
| 3416 | |||
| 3417 | *** New function `current-bidi-paragraph-direction'. | ||
| 3418 | This returns the base direction of the paragraph at point. | ||
| 3419 | |||
| 3420 | *** New function `bidi-string-mark-left-to-right'. | ||
| 3421 | Given a string containing characters from right-to-left scripts, this | ||
| 3422 | function returns another string which can be safely inserted into a | ||
| 3423 | buffer, such that any following text will be always displayed to the | ||
| 3424 | right of that string. (This works by appending an invisible Unicode | ||
| 3425 | "LEFT-TO-RIGHT MARK" character if the argument string might need it.) | ||
| 3426 | |||
| 3427 | This is useful when the buffer has overall left-to-right paragraph | ||
| 3428 | direction and you need to insert a string whose contents are not known | ||
| 3429 | in advance, without disrupting the layout of the line. | ||
| 3430 | |||
| 3431 | ** Window changes | ||
| 3432 | |||
| 3433 | *** Window tree functions are accessible in Elisp. | ||
| 3434 | Functions are provided to return the parent, siblings or child windows | ||
| 3435 | of any window including internal windows (windows not associated with a | ||
| 3436 | buffer) in the window tree. | ||
| 3437 | |||
| 3438 | **** New function `window-valid-p' gives non-nil for live and internal | ||
| 3439 | windows. | ||
| 3440 | |||
| 3441 | **** Window manipulation can deal with internal windows. | ||
| 3442 | Many window handling functions like `split-window', `delete-window', or | ||
| 3443 | `delete-other-windows' as well as the window resizing functions can now | ||
| 3444 | act on any window including internal ones. | ||
| 3445 | |||
| 3446 | *** window-total-height/-width vs window-body-height/-width. | ||
| 3447 | The function `window-height' has been renamed to `window-total-height' | ||
| 3448 | and `window-width' has been renamed to `window-body-width'. The old | ||
| 3449 | names are provided as aliases. Two new functions `window-total-width' | ||
| 3450 | and `window-body-height' are provided. | ||
| 3451 | |||
| 3452 | *** Window parameters specific to window handling functions. | ||
| 3453 | For each window you can specify a parameter to override the default | ||
| 3454 | behavior of a number of functions like `split-window', `delete-window' | ||
| 3455 | and `delete-other-windows'. The variable `ignore-window-parameters' | ||
| 3456 | allows to ignore processing such parameters. | ||
| 3457 | |||
| 3458 | *** New semantics of third argument of `split-window'. | ||
| 3459 | The third argument of `split-window' has been renamed to SIDE and can be | ||
| 3460 | set to any of the values 'below, 'right, 'above, or 'left to make the | ||
| 3461 | new window appear on the corresponding side of the window that shall be | ||
| 3462 | split. Any other value of SIDE will cause `split-window' to split the | ||
| 3463 | window into two side-by-side windows as before. | ||
| 3464 | |||
| 3465 | *** Window resizing functions. | ||
| 3466 | A new standard function for resizing windows called `window-resize' has | ||
| 3467 | been introduced. This and all other functions for resizing windows no | ||
| 3468 | longer delete any windows when they become too small. | ||
| 3469 | |||
| 3470 | *** Deleting the selected window now selects the most recently selected | ||
| 3471 | live window on that frame instead. | ||
| 3472 | |||
| 3473 | *** `adjust-window-trailing-edge' adjustments. | ||
| 3474 | `adjust-window-trailing-edge' can now deal with fixed-size windows and | ||
| 3475 | is able to resize other windows if a window adjacent to the trailing | ||
| 3476 | edge cannot be shrunk any more. This makes its behavior more similar to | ||
| 3477 | that of Emacs 21 without compromising, however, its inability to delete | ||
| 3478 | windows which was introduced in Emacs 22. | ||
| 3479 | |||
| 3480 | *** Window-local buffer lists. | ||
| 3481 | Windows now have local buffer lists. This means that removing a buffer | ||
| 3482 | from display in a window will preferably show the buffer previously | ||
| 3483 | shown in that window with its previous window-start and window-point | ||
| 3484 | positions. This also means that the same buffer may be automatically | ||
| 3485 | shown twice even if it already appears in another window. | ||
| 3486 | |||
| 3487 | *** `switch-to-buffer' has a new optional argument FORCE-SAME-WINDOW, | ||
| 3488 | which if non-nil requires the buffer to be displayed in the currently | ||
| 3489 | selected window, signaling an error otherwise. If nil, another window | ||
| 3490 | can be used, e.g. if the selected one is strongly dedicated. | ||
| 3491 | |||
| 3492 | *** `split-window-vertically' and `split-window-horizontally' renamed | ||
| 3493 | to `split-window-below' and `split-window-right' respectively. | ||
| 3494 | The old names are kept as aliases. | ||
| 3495 | |||
| 3496 | *** Display actions | ||
| 3497 | |||
| 3498 | **** The second arg to `display-buffer' and `pop-to-buffer' is now | ||
| 3499 | named ACTION, and takes a display action of the same form as | ||
| 3500 | `display-buffer-base-action' (see Changes, above). A non-nil, | ||
| 3501 | non-list value is treated specially, as the old meaning. | ||
| 3502 | |||
| 3503 | **** New variable `display-buffer-overriding-action'. | ||
| 3504 | |||
| 3505 | **** The procedure of `display-buffer' etc. to choose a window is | ||
| 3506 | determined by combining `display-buffer-overriding-action', | ||
| 3507 | `display-buffer-alist', the ACTION arg, `display-buffer-base-action', | ||
| 3508 | and `display-buffer-fallback-action'. The second and fourth of these | ||
| 3509 | are user-customizable variables. | ||
| 3510 | |||
| 3511 | See the docstring of `display-buffer' for details. | ||
| 3512 | |||
| 3513 | *** New functions `window-state-get' and `window-state-put'. | ||
| 3514 | These functions allow to save and restore the state of an arbitrary | ||
| 3515 | frame or window as an Elisp object. | ||
| 3516 | |||
| 3517 | ** Completion | ||
| 3518 | |||
| 3519 | *** New variable `completion-extra-properties' used to specify extra | ||
| 3520 | properties of the current completion: | ||
| 3521 | - :annotate-function, same as the old completion-annotate-function. | ||
| 3522 | - :exit-function, function to call after completion took place. | ||
| 3523 | |||
| 3524 | *** Functions on `completion-at-point-functions' can return any of the | ||
| 3525 | properties valid for `completion-extra-properties'. | ||
| 3526 | |||
| 3527 | *** `completion-annotate-function' is obsolete. | ||
| 3528 | |||
| 3529 | *** New `metadata' method for completion tables. The metadata thus returned | ||
| 3530 | can specify various details of the data returned by `all-completions': | ||
| 3531 | - `category' is the kind of objects returned (e.g., `buffer', `file', ...), | ||
| 3532 | used to select a style in completion-category-overrides. | ||
| 3533 | - `annotation-function' to add annotations in *Completions*. | ||
| 3534 | - `display-sort-function' to specify how to sort entries in *Completions*. | ||
| 3535 | - `cycle-sort-function' to specify how to sort entries when cycling. | ||
| 3536 | |||
| 3537 | *** `minibuffer-local-filename-must-match-map' is not used any more. | ||
| 3538 | Instead, the bindings in `minibuffer-local-filename-completion-map' | ||
| 3539 | are combined with `minibuffer-local-must-match-map'. | ||
| 3540 | |||
| 3541 | *** New variable `completing-read-function' allows overriding the | ||
| 3542 | behavior of `completing-read'. | ||
| 3543 | |||
| 3544 | ** `glyphless-char-display' can now distinguish between graphical and | ||
| 3545 | text terminal display, via a char-table entry that is a cons cell. | ||
| 3546 | |||
| 3547 | ** `pre-command-hook'/`post-command-hook' are not reset to nil on error. | ||
| 3548 | Instead, the offending function is removed. | ||
| 3549 | |||
| 3550 | ** New hook types | ||
| 3551 | |||
| 3552 | *** New function `run-hook-wrapped' for running an abnormal hook by | ||
| 3553 | passing the hook functions as arguments to a "wrapping" function. | ||
| 3554 | Like `run-hook-with-args-until-success', it stops at the first | ||
| 3555 | non-nil return value. | ||
| 3556 | |||
| 3557 | *** New macro `with-wrapper-hook' for running an abnormal hook as a | ||
| 3558 | set of "wrapping" filters, similar to around advice. | ||
| 3559 | (A version of this macro was actually added in Emacs 23.2 but was not | ||
| 3560 | advertised at the time.) | ||
| 3561 | |||
| 3562 | ** Debugger changes | ||
| 3563 | |||
| 3564 | *** New macro `condition-case-unless-debug' (this was actually added in | ||
| 3565 | Emacs 23.1 as condition-case-no-debug, but not advertised) | ||
| 3566 | |||
| 3567 | *** The macro `with-demoted-errors' was added in Emacs 23.1, but not advertised. | ||
| 3568 | |||
| 3569 | *** Variable `stack-trace-on-error' removed. | ||
| 3570 | |||
| 3571 | *** The debugger can now "continue" from an error, which means it will | ||
| 3572 | jump to the error handler as if the debugger had not been invoked | ||
| 3573 | instead of jumping all the way to the top-level. | ||
| 3574 | |||
| 3575 | *** Set `debug-on-event' to enter the debugger on events like SIGUSR1. | ||
| 3576 | This can be useful when `inhibit-quit' is set. | ||
| 3577 | |||
| 3578 | ** The new function `server-eval-at' allows evaluation of Lisp forms on | ||
| 3579 | named Emacs server instances. | ||
| 3580 | |||
| 3581 | ** `call-process' and `call-process-region' allow a `(:file "file")' spec | ||
| 3582 | to redirect STDOUT to a file. | ||
| 3583 | |||
| 3584 | ** The function `format-time-string' now supports the %N directive, | ||
| 3585 | for higher-resolution time stamps. | ||
| 3586 | |||
| 3587 | ** New input reading functions | ||
| 3588 | |||
| 3589 | *** New function `read-char-choice' reads a restricted set of | ||
| 3590 | characters, discarding any inputs not inside the set. | ||
| 3591 | |||
| 3592 | *** The command `read-color' now requires a match for a color name | ||
| 3593 | or RGB triplet, instead of signaling an error if the user provides | ||
| 3594 | invalid input. | ||
| 3595 | |||
| 3596 | **** `facemenu-read-color' is now an alias for `read-color'. | ||
| 3597 | |||
| 3598 | ** `image-library-alist' is renamed to `dynamic-library-alist'. | ||
| 3599 | The variable is now used to load all kind of supported dynamic libraries, | ||
| 3600 | not just image libraries. The previous name is still available as an | ||
| 3601 | obsolete alias. | ||
| 3602 | |||
| 3603 | ** Syntax parsing changes | ||
| 3604 | |||
| 3605 | *** New variable `syntax-propertize-function'. | ||
| 3606 | This replaces `font-lock-syntactic-keywords' which is now obsolete. | ||
| 3607 | This allows syntax-table properties to be set independently from font-lock: | ||
| 3608 | just call syntax-propertize to make sure the text is propertized. | ||
| 3609 | Together with this new variable come a new hook | ||
| 3610 | syntax-propertize-extend-region-functions, as well as two helper functions: | ||
| 3611 | syntax-propertize-via-font-lock to reuse old font-lock-syntactic-keywords | ||
| 3612 | as-is; and syntax-propertize-rules which provides a new way to specify | ||
| 3613 | syntactic rules. | ||
| 3614 | |||
| 3615 | *** Syntax tables support a new "comment style c" additionally to style b. | ||
| 3616 | |||
| 3617 | ** New hook `post-self-insert-hook', run after `self-insert-command'. | ||
| 3618 | |||
| 3619 | ** frame-local variables cannot be let-bound any more. | ||
| 3620 | |||
| 3621 | ** Major and minor mode changes | ||
| 3622 | |||
| 3623 | *** `set-auto-mode' now respects mode: local variables at the end of files, | ||
| 3624 | as well as those in the -*- line. | ||
| 3625 | |||
| 3626 | *** `prog-mode' is a new major mode from which programming modes | ||
| 3627 | should be derived. | ||
| 3628 | |||
| 3629 | **** `prog-mode-hook' can be used to enable features for programming | ||
| 3630 | modes, e.g. (add-hook 'prog-mode-hook 'flyspell-prog-mode) to enable | ||
| 3631 | on-the-fly spell checking for comments and strings. | ||
| 3632 | |||
| 3633 | *** New hook `change-major-mode-after-body-hook', run by | ||
| 3634 | `run-mode-hooks' just before any other mode hooks. | ||
| 3635 | |||
| 3636 | *** Enabled globalized minor modes can be disabled in specific major modes. | ||
| 3637 | If the global mode is global-FOO-mode, then run (FOO-mode -1) in the | ||
| 3638 | major mode's hook, where FOO-mode toggles the mode on a per-buffer basis. | ||
| 3639 | |||
| 3640 | *** `define-minor-mode' accepts new keywords :variable, :after-hook. | ||
| 3641 | |||
| 3642 | ** File-handling changes | ||
| 3643 | |||
| 3644 | *** `delete-file' and `delete-directory' now accept optional arg TRASH. | ||
| 3645 | Trashing is performed if TRASH and `delete-by-moving-to-trash' are | ||
| 3646 | both non-nil. Interactively, TRASH defaults to t, unless a prefix | ||
| 3647 | argument is supplied (see Trash changes, above). | ||
| 3648 | |||
| 3649 | *** New file predicates: `file-equal-p', `file-in-directory-p'. | ||
| 3650 | |||
| 3651 | ** Tool-bars can display separators. | ||
| 3652 | Tool-bar separators are handled like menu separators in menu-bar maps, | ||
| 3653 | i.e. via menu entries of the form `(menu-item "--")'. | ||
| 3654 | |||
| 3655 | ** Image API | ||
| 3656 | |||
| 3657 | *** Animated images support (currently animated gifs only). | ||
| 3658 | |||
| 3659 | **** `image-animated-p' returns non-nil if an image can be animated. | ||
| 3660 | |||
| 3661 | **** `image-animate' animates a supplied image spec. | ||
| 3662 | |||
| 3663 | **** `image-animate-timer' returns the timer object for an image that | ||
| 3664 | is being animated. | ||
| 3665 | |||
| 3666 | *** `image-extension-data' has been renamed to `image-metadata'. | ||
| 3667 | The old name is an obsolete alias to the new one. | ||
| 3668 | |||
| 3669 | *** Image mode can view any image type that ImageMagick supports. | ||
| 3670 | This requires Emacs to be built with ImageMagick support. | ||
| 3671 | |||
| 3672 | **** New function `imagemagick-types', defined if ImageMagick support | ||
| 3673 | is enabled, returns a list of image file extensions that your | ||
| 3674 | ImageMagick installation supports. | ||
| 3675 | |||
| 3676 | **** New function `imagemagick-register-types' enables ImageMagick | ||
| 3677 | image types in Image mode and in `create-image' and other helper | ||
| 3678 | functions. | ||
| 3679 | |||
| 3680 | **** New option `imagemagick-types-inhibit' excludes certain | ||
| 3681 | ImageMagick image types from `imagemagick-register-types'. | ||
| 3682 | |||
| 3683 | **** With ImageMagick support, there are extra Image mode commands to | ||
| 3684 | resize and rotate images: `image-transform-fit-to-height', | ||
| 3685 | `image-transform-fit-to-width', `image-transform-set-rotation', and | ||
| 3686 | `image-transform-set-scale'. | ||
| 3687 | |||
| 3688 | ** `compose-mail' now accepts an optional 8th arg, RETURN-ACTION, and | ||
| 3689 | passes it to the mail user agent function. This argument specifies an | ||
| 3690 | action for returning to the caller after finishing with the mail. For | ||
| 3691 | example, this is used by Rmail to optionally delete a mail window. | ||
| 3692 | |||
| 3693 | ** XML and HTML parsing | ||
| 3694 | If Emacs is compiled with libxml2 support, there are two new | ||
| 3695 | functions: `libxml-parse-html-region' (which parses "real world" HTML) | ||
| 3696 | and `libxml-parse-xml-region' (which parses XML). Both return an | ||
| 3697 | Emacs Lisp parse tree. | ||
| 3698 | |||
| 3699 | ** Networking and encryption changes | ||
| 3700 | |||
| 3701 | *** `open-network-stream' can now be used to open an encrypted stream. | ||
| 3702 | It now accepts an optional `:type' parameter for initiating a TLS | ||
| 3703 | connection, directly or via STARTTLS. To do STARTTLS, additional | ||
| 3704 | parameters (`:end-of-command', `:success', `:capabilities-command') | ||
| 3705 | must also be supplied. | ||
| 3706 | |||
| 3707 | *** New library gnutls.el. | ||
| 3708 | The new function `gnutls-available-p' returns non-nil if Emacs is | ||
| 3709 | built with GnuTLS support. The main entry points are | ||
| 3710 | `open-gnutls-stream' and `gnutls-negotiate'. It's easiest to use | ||
| 3711 | these functions through `open-network-stream', because that can | ||
| 3712 | upgrade connections through STARTTLS opportunistically or use plain | ||
| 3713 | SSL, depending on your needs. For debugging, set `gnutls-log-level' | ||
| 3714 | greater than 0. | ||
| 3715 | |||
| 3716 | *** New primitive `secure-hash' that supports many secure hash algorithms: | ||
| 3717 | md5, sha1, sha2, sha224, sha256, sha384, and sha512. The lisp library | ||
| 3718 | sha1.el has been removed. The `sha1' feature is provided by default. | ||
| 3719 | |||
| 3720 | ** Isearch | ||
| 3721 | |||
| 3722 | *** New hook `isearch-update-post-hook' that runs in `isearch-update'. | ||
| 3723 | |||
| 3724 | ** Progress reporters can now "spin". | ||
| 3725 | The MIN-VALUE and MAX-VALUE arguments of `make-progress-reporter' can | ||
| 3726 | now be nil, or omitted. This makes a "non-numeric" reporter. Each | ||
| 3727 | time you call `progress-reporter-update' on that progress reporter, | ||
| 3728 | with a nil or omitted VALUE argument, the reporter message is | ||
| 3729 | displayed with a "spinning bar". | ||
| 3730 | |||
| 3731 | ** New variable `revert-buffer-in-progress-p' is true while a buffer is | ||
| 3732 | being reverted, even if the buffer has a local `revert-buffer-function'. | ||
| 3733 | |||
| 3734 | ** New variables `delayed-warnings-list' and `delayed-warnings-hook'. | ||
| 3735 | If delayed-warnings-list is non-nil, the command loop calls | ||
| 3736 | `delayed-warnings-hook' after `post-command-hook'. At present, this | ||
| 3737 | is only used by Emacs on some platforms to display warnings during | ||
| 3738 | startup, which might otherwise not be noticed. This uses the | ||
| 3739 | functions `display-delayed-warnings' and `collapse-delayed-warnings'. | ||
| 3740 | |||
| 3741 | ** rx.el has a new `group-n' construct for explicitly numbered groups. | ||
| 3742 | |||
| 3743 | ** New function `make-composed-keymap' that constructs a new keymap | ||
| 3744 | from multiple input maps. You can use this to make a keymap that | ||
| 3745 | inherits from multiple maps, eg: | ||
| 3746 | (set-keymap-parent newmap (make-composed-keymap othermap parent)) | ||
| 3747 | |||
| 3748 | ** New function `string-prefix-p'. | ||
| 3749 | (This was actually added in Emacs 23.2 but was not advertised at the time.) | ||
| 3750 | |||
| 3751 | ** New reader macro ## that stands for the empty symbol. | ||
| 3752 | This means that the empty symbol can now be read back. Also, #: by itself | ||
| 3753 | (when not immediately followed by a possible symbol character) stands for | ||
| 3754 | an empty uninterned symbol. | ||
| 3755 | |||
| 3756 | ** New math functions `isnan', `copysign', `frexp', `ldexp'. | ||
| 3757 | |||
| 3758 | ** The following functions and variables are obsolete: | ||
| 3759 | |||
| 3760 | *** `tooltip-use-echo-area' is obsolete. | ||
| 3761 | Rather than setting this to t, disable Tooltip mode instead. | ||
| 3762 | |||
| 3763 | *** buffer-substring-filters is obsolete. | ||
| 3764 | Use `filter-buffer-substring-functions' instead. | ||
| 3765 | |||
| 3766 | *** `byte-compile-disable-print-circle' is obsolete. | ||
| 3767 | |||
| 3768 | *** `deferred-action-list' and `deferred-action-function' are obsolete. | ||
| 3769 | Use `post-command-hook' instead. | ||
| 3770 | |||
| 3771 | *** `font-lock-maximum-size' is obsolete. | ||
| 3772 | |||
| 3773 | |||
| 3774 | * Changes in Emacs 24.1 on Non-Free Operating Systems | ||
| 3775 | |||
| 3776 | ** On MS Windows, Emacs warns when using the obsolete init file _emacs, | ||
| 3777 | and also when HOME is set to C:\ by default. | ||
| 3778 | |||
| 3779 | ** New configure.bat options | ||
| 3780 | |||
| 3781 | *** --enable-checking builds Emacs with extra runtime checks. | ||
| 3782 | |||
| 3783 | *** --distfiles specifies files to be included in binary distribution. | ||
| 3784 | |||
| 3785 | *** --without-gnutls disables automatic GnuTLS detection. | ||
| 3786 | |||
| 3787 | *** --lib for general library linkage, works with the USER_LIBS build variable. | ||
| 3788 | |||
| 3789 | ** New make target `dist' to create binary distribution for MS Windows. | ||
| 3790 | |||
| 3791 | ** The Lisp function `w32-default-color-map' is now obsolete. | ||
| 3792 | (It is only used internally in the Emacs C code.) | ||
| 3793 | |||
| 3794 | ** Customize ns-auto-hide-menu-bar to have the menu-bar hidden, but | ||
| 3795 | reappear on mouse-over. (Requires OS X 10.6 or later.) | ||
| 3796 | |||
| 3797 | ** On Mac OS X, dragging a file into Emacs visits the file, like on | ||
| 3798 | other platforms, rather than inserting its contents into the buffer. | ||
| 3799 | |||
