| 8657 | * Emacs 19.34 is a bug-fix release with no user-visible changes. | ||
| 8658 | |||
| 8659 | * Changes in Emacs 19.33. | ||
| 8660 | |||
| 8661 | ** Bibtex mode no longer turns on Auto Fill automatically. (No major | ||
| 8662 | mode should do that--it is the user's choice.) | ||
| 8663 | |||
| 8664 | ** The variable normal-auto-fill-function specifies the function to | ||
| 8665 | use for auto-fill-function, if and when Auto Fill is turned on. | ||
| 8666 | Major modes can set this locally to alter how Auto Fill works. | ||
| 8667 | |||
| 8668 | * Editing Changes in Emacs 19.32 | ||
| 8669 | |||
| 8670 | ** C-x f with no argument now signals an error. | ||
| 8671 | To set the fill column at the current column, use C-u C-x f. | ||
| 8672 | |||
| 8673 | ** Expanding dynamic abbrevs with M-/ is now smarter about case | ||
| 8674 | conversion. If you type the abbreviation with mixed case, and it | ||
| 8675 | matches the beginning of the expansion including case, then the | ||
| 8676 | expansion is copied verbatim. Using SPC M-/ to copy an additional | ||
| 8677 | word always copies it verbatim except when the previous copied word is | ||
| 8678 | all caps. | ||
| 8679 | |||
| 8680 | ** On a non-windowing terminal, which can display only one Emacs frame | ||
| 8681 | at a time, creating a new frame with C-x 5 2 also selects that frame. | ||
| 8682 | |||
| 8683 | When using a display that can show multiple frames at once, C-x 5 2 | ||
| 8684 | does make the frame visible, but does not select it. This is the same | ||
| 8685 | as in previous Emacs versions. | ||
| 8686 | |||
| 8687 | ** You can use C-x 5 2 to create multiple frames on MSDOS, just as on a | ||
| 8688 | non-X terminal on Unix. Of course, only one frame is visible at any | ||
| 8689 | time, since your terminal doesn't have the ability to display multiple | ||
| 8690 | frames. | ||
| 8691 | |||
| 8692 | ** On Windows, set win32-pass-alt-to-system to a non-nil value | ||
| 8693 | if you would like tapping the Alt key to invoke the Windows menu. | ||
| 8694 | This feature is not enabled by default; since the Alt key is also the | ||
| 8695 | Meta key, it is too easy and painful to activate this feature by | ||
| 8696 | accident. | ||
| 8697 | |||
| 8698 | ** The command apply-macro-to-region-lines repeats the last defined | ||
| 8699 | keyboard macro once for each complete line within the current region. | ||
| 8700 | It does this line by line, by moving point to the beginning of that | ||
| 8701 | line and then executing the macro. | ||
| 8702 | |||
| 8703 | This command is not new, but was never documented before. | ||
| 8704 | |||
| 8705 | ** You can now use Mouse-1 to place the region around a string constant | ||
| 8706 | (something surrounded by doublequote characters or other delimiter | ||
| 8707 | characters of like syntax) by double-clicking on one of the delimiting | ||
| 8708 | characters. | ||
| 8709 | |||
| 8710 | ** Font Lock mode | ||
| 8711 | |||
| 8712 | *** Font Lock support modes | ||
| 8713 | |||
| 8714 | Font Lock can be configured to use Fast Lock mode and Lazy Lock mode (see | ||
| 8715 | below) in a flexible way. Rather than adding the appropriate function to the | ||
| 8716 | hook font-lock-mode-hook, you can use the new variable font-lock-support-mode | ||
| 8717 | to control which modes have Fast Lock mode or Lazy Lock mode turned on when | ||
| 8718 | Font Lock mode is enabled. | ||
| 8719 | |||
| 8720 | For example, to use Fast Lock mode when Font Lock mode is turned on, put: | ||
| 8721 | |||
| 8722 | (setq font-lock-support-mode 'fast-lock-mode) | ||
| 8723 | |||
| 8724 | in your ~/.emacs. | ||
| 8725 | |||
| 8726 | *** lazy-lock | ||
| 8727 | |||
| 8728 | The lazy-lock package speeds up Font Lock mode by making fontification occur | ||
| 8729 | only when necessary, such as when a previously unfontified part of the buffer | ||
| 8730 | becomes visible in a window. When you create a buffer with Font Lock mode and | ||
| 8731 | Lazy Lock mode turned on, the buffer is not fontified. When certain events | ||
| 8732 | occur (such as scrolling), Lazy Lock makes sure that the visible parts of the | ||
| 8733 | buffer are fontified. Lazy Lock also defers on-the-fly fontification until | ||
| 8734 | Emacs has been idle for a given amount of time. | ||
| 8735 | |||
| 8736 | To use this package, put in your ~/.emacs: | ||
| 8737 | |||
| 8738 | (setq font-lock-support-mode 'lazy-lock-mode) | ||
| 8739 | |||
| 8740 | To control the package behaviour, see the documentation for `lazy-lock-mode'. | ||
| 8741 | |||
| 8742 | ** Changes in BibTeX mode. | ||
| 8743 | |||
| 8744 | *** For all entries allow spaces and tabs between opening brace or | ||
| 8745 | paren and key. | ||
| 8746 | |||
| 8747 | *** Non-escaped double-quoted characters (as in `Sch"of') are now | ||
| 8748 | supported. | ||
| 8749 | |||
| 8750 | ** Gnus changes. | ||
| 8751 | |||
| 8752 | Gnus, the Emacs news reader, has undergone further rewriting. Many new | ||
| 8753 | commands and variables have been added. There should be no | ||
| 8754 | significant incompatibilities between this Gnus version and the | ||
| 8755 | previously released version, except in the message composition area. | ||
| 8756 | |||
| 8757 | Below is a list of the more user-visible changes. Coding changes | ||
| 8758 | between Gnus 5.1 and 5.2 are more extensive. | ||
| 8759 | |||
| 8760 | *** A new message composition mode is used. All old customization | ||
| 8761 | variables for mail-mode, rnews-reply-mode and gnus-msg are now | ||
| 8762 | obsolete. | ||
| 8763 | |||
| 8764 | *** Gnus is now able to generate "sparse" threads -- threads where | ||
| 8765 | missing articles are represented by empty nodes. | ||
| 8766 | |||
| 8767 | (setq gnus-build-sparse-threads 'some) | ||
| 8768 | |||
| 8769 | *** Outgoing articles are stored on a special archive server. | ||
| 8770 | |||
| 8771 | To disable this: (setq gnus-message-archive-group nil) | ||
| 8772 | |||
| 8773 | *** Partial thread regeneration now happens when articles are | ||
| 8774 | referred. | ||
| 8775 | |||
| 8776 | *** Gnus can make use of GroupLens predictions: | ||
| 8777 | |||
| 8778 | (setq gnus-use-grouplens t) | ||
| 8779 | |||
| 8780 | *** A trn-line tree buffer can be displayed. | ||
| 8781 | |||
| 8782 | (setq gnus-use-trees t) | ||
| 8783 | |||
| 8784 | *** An nn-like pick-and-read minor mode is available for the summary | ||
| 8785 | buffers. | ||
| 8786 | |||
| 8787 | (add-hook 'gnus-summary-mode-hook 'gnus-pick-mode) | ||
| 8788 | |||
| 8789 | *** In binary groups you can use a special binary minor mode: | ||
| 8790 | |||
| 8791 | `M-x gnus-binary-mode' | ||
| 8792 | |||
| 8793 | *** Groups can be grouped in a folding topic hierarchy. | ||
| 8794 | |||
| 8795 | (add-hook 'gnus-group-mode-hook 'gnus-topic-mode) | ||
| 8796 | |||
| 8797 | *** Gnus can re-send and bounce mail. | ||
| 8798 | |||
| 8799 | Use the `S D r' and `S D b'. | ||
| 8800 | |||
| 8801 | *** Groups can now have a score, and bubbling based on entry frequency | ||
| 8802 | is possible. | ||
| 8803 | |||
| 8804 | (add-hook 'gnus-summary-exit-hook 'gnus-summary-bubble-group) | ||
| 8805 | |||
| 8806 | *** Groups can be process-marked, and commands can be performed on | ||
| 8807 | groups of groups. | ||
| 8808 | |||
| 8809 | *** Caching is possible in virtual groups. | ||
| 8810 | |||
| 8811 | *** nndoc now understands all kinds of digests, mail boxes, rnews news | ||
| 8812 | batches, ClariNet briefs collections, and just about everything else. | ||
| 8813 | |||
| 8814 | *** Gnus has a new backend (nnsoup) to create/read SOUP packets. | ||
| 8815 | |||
| 8816 | *** The Gnus cache is much faster. | ||
| 8817 | |||
| 8818 | *** Groups can be sorted according to many criteria. | ||
| 8819 | |||
| 8820 | For instance: (setq gnus-group-sort-function 'gnus-group-sort-by-rank) | ||
| 8821 | |||
| 8822 | *** New group parameters have been introduced to set list-address and | ||
| 8823 | expiration times. | ||
| 8824 | |||
| 8825 | *** All formatting specs allow specifying faces to be used. | ||
| 8826 | |||
| 8827 | *** There are several more commands for setting/removing/acting on | ||
| 8828 | process marked articles on the `M P' submap. | ||
| 8829 | |||
| 8830 | *** The summary buffer can be limited to show parts of the available | ||
| 8831 | articles based on a wide range of criteria. These commands have been | ||
| 8832 | bound to keys on the `/' submap. | ||
| 8833 | |||
| 8834 | *** Articles can be made persistent -- as an alternative to saving | ||
| 8835 | articles with the `*' command. | ||
| 8836 | |||
| 8837 | *** All functions for hiding article elements are now toggles. | ||
| 8838 | |||
| 8839 | *** Article headers can be buttonized. | ||
| 8840 | |||
| 8841 | (add-hook 'gnus-article-display-hook 'gnus-article-add-buttons-to-head) | ||
| 8842 | |||
| 8843 | *** All mail backends support fetching articles by Message-ID. | ||
| 8844 | |||
| 8845 | *** Duplicate mail can now be treated properly. See the | ||
| 8846 | `nnmail-treat-duplicates' variable. | ||
| 8847 | |||
| 8848 | *** All summary mode commands are available directly from the article | ||
| 8849 | buffer. | ||
| 8850 | |||
| 8851 | *** Frames can be part of `gnus-buffer-configuration'. | ||
| 8852 | |||
| 8853 | *** Mail can be re-scanned by a daemonic process. | ||
| 8854 | |||
| 8855 | *** Gnus can make use of NoCeM files to filter spam. | ||
| 8856 | |||
| 8857 | (setq gnus-use-nocem t) | ||
| 8858 | |||
| 8859 | *** Groups can be made permanently visible. | ||
| 8860 | |||
| 8861 | (setq gnus-permanently-visible-groups "^nnml:") | ||
| 8862 | |||
| 8863 | *** Many new hooks have been introduced to make customizing easier. | ||
| 8864 | |||
| 8865 | *** Gnus respects the Mail-Copies-To header. | ||
| 8866 | |||
| 8867 | *** Threads can be gathered by looking at the References header. | ||
| 8868 | |||
| 8869 | (setq gnus-summary-thread-gathering-function | ||
| 8870 | 'gnus-gather-threads-by-references) | ||
| 8871 | |||
| 8872 | *** Read articles can be stored in a special backlog buffer to avoid | ||
| 8873 | refetching. | ||
| 8874 | |||
| 8875 | (setq gnus-keep-backlog 50) | ||
| 8876 | |||
| 8877 | *** A clean copy of the current article is always stored in a separate | ||
| 8878 | buffer to allow easier treatment. | ||
| 8879 | |||
| 8880 | *** Gnus can suggest where to save articles. See `gnus-split-methods'. | ||
| 8881 | |||
| 8882 | *** Gnus doesn't have to do as much prompting when saving. | ||
| 8883 | |||
| 8884 | (setq gnus-prompt-before-saving t) | ||
| 8885 | |||
| 8886 | *** gnus-uu can view decoded files asynchronously while fetching | ||
| 8887 | articles. | ||
| 8888 | |||
| 8889 | (setq gnus-uu-grabbed-file-functions 'gnus-uu-grab-view) | ||
| 8890 | |||
| 8891 | *** Filling in the article buffer now works properly on cited text. | ||
| 8892 | |||
| 8893 | *** Hiding cited text adds buttons to toggle hiding, and how much | ||
| 8894 | cited text to hide is now customizable. | ||
| 8895 | |||
| 8896 | (setq gnus-cited-lines-visible 2) | ||
| 8897 | |||
| 8898 | *** Boring headers can be hidden. | ||
| 8899 | |||
| 8900 | (add-hook 'gnus-article-display-hook 'gnus-article-hide-boring-headers) | ||
| 8901 | |||
| 8902 | *** Default scoring values can now be set from the menu bar. | ||
| 8903 | |||
| 8904 | *** Further syntax checking of outgoing articles have been added. | ||
| 8905 | |||
| 8906 | The Gnus manual has been expanded. It explains all these new features | ||
| 8907 | in greater detail. | ||
| 8908 | |||
| 8909 | * Lisp Changes in Emacs 19.32 | ||
| 8910 | |||
| 8911 | ** The function set-visited-file-name now accepts an optional | ||
| 8912 | second argument NO-QUERY. If it is non-nil, then the user is not | ||
| 8913 | asked for confirmation in the case where the specified file already | ||
| 8914 | exists. | ||
| 8915 | |||
| 8916 | ** The variable print-length applies to printing vectors and bitvectors, | ||
| 8917 | as well as lists. | ||
| 8918 | |||
| 8919 | ** The new function keymap-parent returns the parent keymap | ||
| 8920 | of a given keymap. | ||
| 8921 | |||
| 8922 | ** The new function set-keymap-parent specifies a new parent for a | ||
| 8923 | given keymap. The arguments are KEYMAP and PARENT. PARENT must be a | ||
| 8924 | keymap or nil. | ||
| 8925 | |||
| 8926 | ** Sometimes menu keymaps use a command name, a symbol, which is really | ||
| 8927 | an automatically generated alias for some other command, the "real" | ||
| 8928 | name. In such a case, you should give that alias symbol a non-nil | ||
| 8929 | menu-alias property. That property tells the menu system to look for | ||
| 8930 | equivalent keys for the real name instead of equivalent keys for the | ||
| 8931 | alias. | ||
| 8932 | |||
| 8933 | * Editing Changes in Emacs 19.31 | ||
| 8934 | |||
| 8935 | ** Freedom of the press restricted in the United States. | ||
| 8936 | |||
| 8937 | Emacs has been censored in accord with the Communications Decency Act. | ||
| 8938 | This includes removing some features of the doctor program. That law | ||
| 8939 | was described by its supporters as a ban on pornography, but it bans | ||
| 8940 | far more than that. The Emacs distribution has never contained any | ||
| 8941 | pornography, but parts of it were nonetheless prohibited. | ||
| 8942 | |||
| 8943 | For information on US government censorship of the Internet, and what | ||
| 8944 | you can do to bring back freedom of the press, see the web site | ||
| 8945 | `http://www.vtw.org/'. | ||
| 8946 | |||
| 8947 | ** A note about C mode indentation customization. | ||
| 8948 | |||
| 8949 | The old (Emacs 19.29) ways of specifying a C indentation style | ||
| 8950 | do not normally work in the new implementation of C mode. | ||
| 8951 | It has its own methods of customizing indentation, which are | ||
| 8952 | much more powerful than the old C mode. See the Editing Programs | ||
| 8953 | chapter of the manual for details. | ||
| 8954 | |||
| 8955 | However, you can load the library cc-compat to make the old | ||
| 8956 | customization variables take effect. | ||
| 8957 | |||
| 8958 | ** Marking with the mouse. | ||
| 8959 | |||
| 8960 | When you mark a region with the mouse, the region now remains | ||
| 8961 | highlighted until the next input event, regardless of whether you are | ||
| 8962 | using M-x transient-mark-mode. | ||
| 8963 | |||
| 8964 | ** Improved Windows NT/95 support. | ||
| 8965 | |||
| 8966 | *** Emacs now supports scroll bars on Windows NT and Windows 95. | ||
| 8967 | |||
| 8968 | *** Emacs now supports subprocesses on Windows 95. (Subprocesses used | ||
| 8969 | to work on NT only and not on 95.) | ||
| 8970 | |||
| 8971 | *** There are difficulties with subprocesses, though, due to problems | ||
| 8972 | in Windows, beyond the control of Emacs. They work fine as long as | ||
| 8973 | you run Windows applications. The problems arise when you run a DOS | ||
| 8974 | application in a subprocesses. Since current shells run as DOS | ||
| 8975 | applications, these problems are significant. | ||
| 8976 | |||
| 8977 | If you run a DOS application in a subprocess, then the application is | ||
| 8978 | likely to busy-wait, which means that your machine will be 100% busy. | ||
| 8979 | However, if you don't mind the temporary heavy load, the subprocess | ||
| 8980 | will work OK as long as you tell it to terminate before you start any | ||
| 8981 | other DOS application as a subprocess. | ||
| 8982 | |||
| 8983 | Emacs is unable to terminate or interrupt a DOS subprocess. | ||
| 8984 | You have to do this by providing input directly to the subprocess. | ||
| 8985 | |||
| 8986 | If you run two DOS applications at the same time in two separate | ||
| 8987 | subprocesses, even if one of them is asynchronous, you will probably | ||
| 8988 | have to reboot your machine--until then, it will remain 100% busy. | ||
| 8989 | Windows simply does not cope when one Windows process tries to run two | ||
| 8990 | separate DOS subprocesses. Typing CTL-ALT-DEL and then choosing | ||
| 8991 | Shutdown seems to work although it may take a few minutes. | ||
| 8992 | |||
| 8993 | ** M-x resize-minibuffer-mode. | ||
| 8994 | |||
| 8995 | This command, not previously mentioned in NEWS, toggles a mode in | ||
| 8996 | which the minibuffer window expands to show as many lines as the | ||
| 8997 | minibuffer contains. | ||
| 8998 | |||
| 8999 | ** `title' frame parameter and resource. | ||
| 9000 | |||
| 9001 | The `title' X resource now specifies just the frame title, nothing else. | ||
| 9002 | It does not affect the name used for looking up other X resources. | ||
| 9003 | It works by setting the new `title' frame parameter, which likewise | ||
| 9004 | affects just the displayed title of the frame. | ||
| 9005 | |||
| 9006 | The `name' parameter continues to do what it used to do: | ||
| 9007 | it specifies the frame name for looking up X resources, | ||
| 9008 | and also serves as the default for the displayed title | ||
| 9009 | when the `title' parameter is unspecified or nil. | ||
| 9010 | |||
| 9011 | ** Emacs now uses the X toolkit by default, if you have a new | ||
| 9012 | enough version of X installed (X11R5 or newer). | ||
| 9013 | |||
| 9014 | ** When you compile Emacs with the Motif widget set, Motif handles the | ||
| 9015 | F10 key by activating the menu bar. To avoid confusion, the usual | ||
| 9016 | Emacs binding of F10 is replaced with a no-op when using Motif. | ||
| 9017 | |||
| 9018 | If you want to be able to use F10 in Emacs, you can rebind the Motif | ||
| 9019 | menubar to some other key which you don't use. To do so, add | ||
| 9020 | something like this to your X resources file. This example rebinds | ||
| 9021 | the Motif menu bar activation key to S-F12: | ||
| 9022 | |||
| 9023 | Emacs*defaultVirtualBindings: osfMenuBar : Shift<Key>F12 | ||
| 9024 | |||
| 9025 | ** In overwrite mode, DEL now inserts spaces in most cases | ||
| 9026 | to replace the characters it "deletes". | ||
| 9027 | |||
| 9028 | ** The Rmail summary now shows the number of lines in each message. | ||
| 9029 | |||
| 9030 | ** Rmail has a new command M-x unforward-rmail-message, which extracts | ||
| 9031 | a forwarded message from the message that forwarded it. To use it, | ||
| 9032 | select a message which contains a forwarded message and then type the command. | ||
| 9033 | It inserts the forwarded message as a separate Rmail message | ||
| 9034 | immediately after the selected one. | ||
| 9035 | |||
| 9036 | This command also undoes the textual modifications that are standardly | ||
| 9037 | made, as part of forwarding, by Rmail and other mail reader programs. | ||
| 9038 | |||
| 9039 | ** Turning off saving of .saves-... files in your home directory. | ||
| 9040 | |||
| 9041 | Each Emacs session writes a file named .saves-... in your home | ||
| 9042 | directory to record which files M-x recover-session should recover. | ||
| 9043 | If you exit Emacs normally with C-x C-c, it deletes that file. If | ||
| 9044 | Emacs or the operating system crashes, the file remains for M-x | ||
| 9045 | recover-session. | ||
| 9046 | |||
| 9047 | You can turn off the writing of these files by setting | ||
| 9048 | auto-save-list-file-name to nil. If you do this, M-x recover-session | ||
| 9049 | will not work. | ||
| 9050 | |||
| 9051 | Some previous Emacs versions failed to delete these files even on | ||
| 9052 | normal exit. This is fixed now. If you are thinking of turning off | ||
| 9053 | this feature because of past experiences with versions that had this | ||
| 9054 | bug, it would make sense to check whether you still want to do so | ||
| 9055 | now that the bug is fixed. | ||
| 9056 | |||
| 9057 | ** Changes to Version Control (VC) | ||
| 9058 | |||
| 9059 | There is a new variable, vc-follow-symlinks. It indicates what to do | ||
| 9060 | when you visit a link to a file that is under version control. | ||
| 9061 | Editing the file through the link bypasses the version control system, | ||
| 9062 | which is dangerous and probably not what you want. | ||
| 9063 | |||
| 9064 | If this variable is t, VC follows the link and visits the real file, | ||
| 9065 | telling you about it in the echo area. If it is `ask' (the default), | ||
| 9066 | VC asks for confirmation whether it should follow the link. If nil, | ||
| 9067 | the link is visited and a warning displayed. | ||
| 9068 | |||
| 9069 | ** iso-acc.el now lets you specify a choice of language. | ||
| 9070 | Languages include "latin-1" (the default) and "latin-2" (which | ||
| 9071 | is designed for entering ISO Latin-2 characters). | ||
| 9072 | |||
| 9073 | There are also choices for specific human languages such as French and | ||
| 9074 | Portuguese. These are subsets of Latin-1, which differ in that they | ||
| 9075 | enable only the accent characters needed for particular language. | ||
| 9076 | The other accent characters, not needed for the chosen language, | ||
| 9077 | remain normal. | ||
| 9078 | |||
| 9079 | ** Posting articles and sending mail now has M-TAB completion on various | ||
| 9080 | header fields (Newsgroups, To, CC, ...). | ||
| 9081 | |||
| 9082 | Completion in the Newsgroups header depends on the list of groups | ||
| 9083 | known to your news reader. Completion in the Followup-To header | ||
| 9084 | offers those groups which are in the Newsgroups header, since | ||
| 9085 | Followup-To usually just holds one of those. | ||
| 9086 | |||
| 9087 | Completion in fields that hold mail addresses works based on the list | ||
| 9088 | of local users plus your aliases. Additionally, if your site provides | ||
| 9089 | a mail directory or a specific host to use for any unrecognized user | ||
| 9090 | name, you can arrange to query that host for completion also. (See the | ||
| 9091 | documentation of variables `mail-directory-process' and | ||
| 9092 | `mail-directory-stream'.) | ||
| 9093 | |||
| 9094 | ** A greatly extended sgml-mode offers new features such as (to be configured) | ||
| 9095 | skeletons with completing read for tags and attributes, typing named | ||
| 9096 | characters including optionally all 8bit characters, making tags invisible | ||
| 9097 | with optional alternate display text, skipping and deleting tag(pair)s. | ||
| 9098 | |||
| 9099 | Note: since Emacs' syntax feature cannot limit the special meaning of ', " and | ||
| 9100 | - to inside <>, for some texts the result, especially of font locking, may be | ||
| 9101 | wrong (see `sgml-specials' if you get wrong results). | ||
| 9102 | |||
| 9103 | The derived html-mode configures this with tags and attributes more or | ||
| 9104 | less HTML3ish. It also offers optional quick keys like C-c 1 for | ||
| 9105 | headline or C-c u for unordered list (see `html-quick-keys'). Edit / | ||
| 9106 | Text Properties / Face or M-g combinations create tags as applicable. | ||
| 9107 | Outline minor mode is supported and level 1 font-locking tries to | ||
| 9108 | fontify tag contents (which only works when they fit on one line, due | ||
| 9109 | to a limitation in font-lock). | ||
| 9110 | |||
| 9111 | External viewing via browse-url can occur automatically upon saving. | ||
| 9112 | |||
| 9113 | ** M-x imenu-add-to-menubar now adds to the menu bar for the current | ||
| 9114 | buffer only. If you want to put an Imenu item in the menu bar for all | ||
| 9115 | buffers that use a particular major mode, use the mode hook, as in | ||
| 9116 | this example: | ||
| 9117 | |||
| 9118 | (add-hook 'emacs-lisp-mode-hook | ||
| 9119 | '(lambda () (imenu-add-to-menubar "Index"))) | ||
| 9120 | |||
| 9121 | ** Changes in BibTeX mode. | ||
| 9122 | |||
| 9123 | *** Field names may now contain digits, hyphens, and underscores. | ||
| 9124 | |||
| 9125 | *** Font Lock mode is now supported. | ||
| 9126 | |||
| 9127 | *** bibtex-make-optional-field is no longer interactive. | ||
| 9128 | |||
| 9129 | *** If bibtex-maintain-sorted-entries is non-nil, inserting new | ||
| 9130 | entries is now done with a faster algorithm. However, inserting | ||
| 9131 | will fail in this case if the buffer contains invalid entries or | ||
| 9132 | isn't in sorted order, so you should finish each entry with C-c C-c | ||
| 9133 | (bibtex-close-entry) after you have inserted or modified it. | ||
| 9134 | The default value of bibtex-maintain-sorted-entries is nil. | ||
| 9135 | |||
| 9136 | *** Function `show-all' is no longer bound to a key, since C-u C-c C-q | ||
| 9137 | does the same job. | ||
| 9138 | |||
| 9139 | *** Entries with quotes inside quote-delimited fields (as `author = | ||
| 9140 | "Stefan Sch{\"o}f"') are now supported. | ||
| 9141 | |||
| 9142 | *** Case in field names doesn't matter anymore when searching for help | ||
| 9143 | text. | ||
| 9144 | |||
| 9145 | ** Font Lock mode | ||
| 9146 | |||
| 9147 | *** Global Font Lock mode | ||
| 9148 | |||
| 9149 | Font Lock mode can be turned on globally, in buffers that support it, by the | ||
| 9150 | new command global-font-lock-mode. You can use the new variable | ||
| 9151 | font-lock-global-modes to control which modes have Font Lock mode automagically | ||
| 9152 | turned on. By default, this variable is set so that Font Lock mode is turned | ||
| 9153 | on globally where the buffer mode supports it. | ||
| 9154 | |||
| 9155 | For example, to automagically turn on Font Lock mode where supported, put: | ||
| 9156 | |||
| 9157 | (global-font-lock-mode t) | ||
| 9158 | |||
| 9159 | in your ~/.emacs. | ||
| 9160 | |||
| 9161 | *** Local Refontification | ||
| 9162 | |||
| 9163 | In Font Lock mode, editing a line automatically refontifies that line only. | ||
| 9164 | However, if your change alters the syntactic context for following lines, | ||
| 9165 | those lines remain incorrectly fontified. To refontify them, use the new | ||
| 9166 | command M-g M-g (font-lock-fontify-block). | ||
| 9167 | |||
| 9168 | In certain major modes, M-g M-g refontifies the entire current function. | ||
| 9169 | (The variable font-lock-mark-block-function controls how to find the | ||
| 9170 | current function.) In other major modes, M-g M-g refontifies 16 lines | ||
| 9171 | above and below point. | ||
| 9172 | |||
| 9173 | With a prefix argument N, M-g M-g refontifies N lines above and below point. | ||
| 9174 | |||
| 9175 | ** Follow mode | ||
| 9176 | |||
| 9177 | Follow mode is a new minor mode combining windows showing the same | ||
| 9178 | buffer into one tall "virtual window". The windows are typically two | ||
| 9179 | side-by-side windows. Follow mode makes them scroll together as if | ||
| 9180 | they were a unit. To use it, go to a frame with just one window, | ||
| 9181 | split it into two side-by-side windows using C-x 3, and then type M-x | ||
| 9182 | follow-mode. | ||
| 9183 | |||
| 9184 | M-x follow-mode turns off Follow mode if it is already enabled. | ||
| 9185 | |||
| 9186 | To display two side-by-side windows and activate Follow mode, use the | ||
| 9187 | command M-x follow-delete-other-windows-and-split. | ||
| 9188 | |||
| 9189 | ** hide-show changes. | ||
| 9190 | |||
| 9191 | The hooks hs-hide-hooks and hs-show-hooks have been renamed | ||
| 9192 | to hs-hide-hook and hs-show-hook, to follow the convention for | ||
| 9193 | normal hooks. | ||
| 9194 | |||
| 9195 | ** Simula mode now has a menu containing the most important commands. | ||
| 9196 | The new command simula-indent-exp is bound to C-M-q. | ||
| 9197 | |||
| 9198 | ** etags can now handle programs written in Erlang. Files are | ||
| 9199 | recognised by the extensions .erl and .hrl. The tagged lines are | ||
| 9200 | those that begin a function, record, or macro. | ||
| 9201 | |||
| 9202 | ** MSDOS Changes | ||
| 9203 | |||
| 9204 | *** It is now possible to compile Emacs with the version 2 of DJGPP. | ||
| 9205 | Compilation with DJGPP version 1 also still works. | ||
| 9206 | |||
| 9207 | *** The documentation of DOS-specific aspects of Emacs was rewritten | ||
| 9208 | and expanded; see the ``MS-DOS'' node in the on-line docs. | ||
| 9209 | |||
| 9210 | *** Emacs now uses ~ for backup file names, not .bak. | ||
| 9211 | |||
| 9212 | *** You can simulate mouse-3 on two-button mice by simultaneously | ||
| 9213 | pressing both mouse buttons. | ||
| 9214 | |||
| 9215 | *** A number of packages and commands which previously failed or had | ||
| 9216 | restricted functionality on MS-DOS, now work. The most important ones | ||
| 9217 | are: | ||
| 9218 | |||
| 9219 | **** Printing (both with `M-x lpr-buffer' and with `ps-print' package) | ||
| 9220 | now works. | ||
| 9221 | |||
| 9222 | **** `Ediff' works (in a single-frame mode). | ||
| 9223 | |||
| 9224 | **** `M-x display-time' can be used on MS-DOS (due to the new | ||
| 9225 | implementation of Emacs timers, see below). | ||
| 9226 | |||
| 9227 | **** `Dired' supports Unix-style shell wildcards. | ||
| 9228 | |||
| 9229 | **** The `c-macro-expand' command now works as on other platforms. | ||
| 9230 | |||
| 9231 | **** `M-x recover-session' works. | ||
| 9232 | |||
| 9233 | **** `M-x list-colors-display' displays all the available colors. | ||
| 9234 | |||
| 9235 | **** The `TPU-EDT' package works. | ||
| 9236 | |||
| 9237 | * Lisp changes in Emacs 19.31. | ||
| 9238 | |||
| 9239 | ** The function using-unix-filesystems on Windows NT and Windows 95 | ||
| 9240 | tells Emacs to read and write files assuming that they reside on a | ||
| 9241 | remote Unix filesystem. No CR/LF translation is done on any files in | ||
| 9242 | this case. Invoking using-unix-filesystems with t activates this | ||
| 9243 | behavior, and invoking it with any other value deactivates it. | ||
| 9244 | |||
| 9245 | ** Change in system-type and system-configuration values. | ||
| 9246 | |||
| 9247 | The value of system-type on a Linux-based GNU system is now `lignux', | ||
| 9248 | not `linux'. This means that some programs which use `system-type' | ||
| 9249 | need to be changed. The value of `system-configuration' will also | ||
| 9250 | be different. | ||
| 9251 | |||
| 9252 | It is generally recommended to use `system-configuration' rather | ||
| 9253 | than `system-type'. | ||
| 9254 | |||
| 9255 | See the file LINUX-GNU in this directory for more about this. | ||
| 9256 | |||
| 9257 | ** The functions shell-command and dired-call-process | ||
| 9258 | now run file name handlers for default-directory, if it has them. | ||
| 9259 | |||
| 9260 | ** Undoing the deletion of text now restores the positions of markers | ||
| 9261 | that pointed into or next to the deleted text. | ||
| 9262 | |||
| 9263 | ** Timers created with run-at-time now work internally to Emacs, and | ||
| 9264 | no longer use a separate process. Therefore, they now work more | ||
| 9265 | reliably and can be used for shorter time delays. | ||
| 9266 | |||
| 9267 | The new function run-with-timer is a convenient way to set up a timer | ||
| 9268 | to run a specified amount of time after the present. A call looks | ||
| 9269 | like this: | ||
| 9270 | |||
| 9271 | (run-with-timer SECS REPEAT FUNCTION ARGS...) | ||
| 9272 | |||
| 9273 | SECS says how many seconds should elapse before the timer happens. | ||
| 9274 | It may be an integer or a floating point number. When the timer | ||
| 9275 | becomes ripe, the action is to call FUNCTION with arguments ARGS. | ||
| 9276 | |||
| 9277 | REPEAT gives the interval for repeating the timer (measured in | ||
| 9278 | seconds). It may be an integer or a floating point number. nil or 0 | ||
| 9279 | means don't repeat at all--call FUNCTION just once. | ||
| 9280 | |||
| 9281 | *** with-timeout provides an easy way to do something but give | ||
| 9282 | up if too much time passes. | ||
| 9283 | |||
| 9284 | (with-timeout (SECONDS TIMEOUT-FORMS...) BODY...) | ||
| 9285 | |||
| 9286 | This executes BODY, but gives up after SECONDS seconds. | ||
| 9287 | If it gives up, it runs the TIMEOUT-FORMS and returns the value | ||
| 9288 | of the last one of them. Normally it returns the value of the last | ||
| 9289 | form in BODY. | ||
| 9290 | |||
| 9291 | *** You can now arrange to call a function whenever Emacs is idle for | ||
| 9292 | a certain length of time. To do this, call run-with-idle-timer. A | ||
| 9293 | call looks like this: | ||
| 9294 | |||
| 9295 | (run-with-idle-timer SECS REPEAT FUNCTION ARGS...) | ||
| 9296 | |||
| 9297 | SECS says how many seconds of idleness should elapse before the timer | ||
| 9298 | runs. It may be an integer or a floating point number. When the | ||
| 9299 | timer becomes ripe, the action is to call FUNCTION with arguments | ||
| 9300 | ARGS. | ||
| 9301 | |||
| 9302 | Emacs becomes idle whenever it finishes executing a keyboard or mouse | ||
| 9303 | command. It remains idle until it receives another keyboard or mouse | ||
| 9304 | command. | ||
| 9305 | |||
| 9306 | REPEAT, if non-nil, means this timer should be activated again each | ||
| 9307 | time Emacs becomes idle and remains idle for SECS seconds The timer | ||
| 9308 | does not repeat if Emacs *remains* idle; it runs at most once after | ||
| 9309 | each time Emacs becomes idle. | ||
| 9310 | |||
| 9311 | If REPEAT is nil, the timer runs just once, the first time Emacs is | ||
| 9312 | idle for SECS seconds. | ||
| 9313 | |||
| 9314 | *** post-command-idle-hook is now obsolete; you shouldn't use it at | ||
| 9315 | all, because it interferes with the idle timer mechanism. If your | ||
| 9316 | programs use post-command-idle-hook, convert them to use idle timers | ||
| 9317 | instead. | ||
| 9318 | |||
| 9319 | *** y-or-n-p-with-timeout lets you ask a question but give up if | ||
| 9320 | there is no answer within a certain time. | ||
| 9321 | |||
| 9322 | (y-or-n-p-with-timeout PROMPT SECONDS DEFAULT-VALUE) | ||
| 9323 | |||
| 9324 | asks the question PROMPT (just like y-or-n-p). If the user answers | ||
| 9325 | within SECONDS seconds, it returns the answer that the user gave. | ||
| 9326 | Otherwise it gives up after SECONDS seconds, and returns DEFAULT-VALUE. | ||
| 9327 | |||
| 9328 | ** Minor change to `encode-time': you can now pass more than seven | ||
| 9329 | arguments. If you do that, the first six arguments have the usual | ||
| 9330 | meaning, the last argument is interpreted as the time zone, and the | ||
| 9331 | arguments in between are ignored. | ||
| 9332 | |||
| 9333 | This means that it works to use the list returned by `decode-time' as | ||
| 9334 | the list of arguments for `encode-time'. | ||
| 9335 | |||
| 9336 | ** The default value of load-path now includes the directory | ||
| 9337 | /usr/local/share/emacs/VERSION/site-lisp In addition to | ||
| 9338 | /usr/local/share/emacs/site-lisp. You can use this new directory for | ||
| 9339 | site-specific Lisp packages that belong with a particular Emacs | ||
| 9340 | version. | ||
| 9341 | |||
| 9342 | It is not unusual for a Lisp package that works well in one Emacs | ||
| 9343 | version to cause trouble in another. Sometimes packages need updating | ||
| 9344 | for incompatible changes; sometimes they look at internal data that | ||
| 9345 | has changed; sometimes the package has been installed in Emacs itself | ||
| 9346 | and the installed version should be used. Whatever the reason for the | ||
| 9347 | problem, this new feature makes it easier to solve. | ||
| 9348 | |||
| 9349 | ** When your program contains a fixed file name (like .completions or | ||
| 9350 | .abbrev.defs), the file name usually needs to be different on operating | ||
| 9351 | systems with limited file name syntax. | ||
| 9352 | |||
| 9353 | Now you can avoid ad-hoc conditionals by using the function | ||
| 9354 | convert-standard-filename to convert the file name to a proper form | ||
| 9355 | for each operating system. Here is an example of use, from the file | ||
| 9356 | completions.el: | ||
| 9357 | |||
| 9358 | (defvar save-completions-file-name | ||
| 9359 | (convert-standard-filename "~/.completions") | ||
| 9360 | "*The filename to save completions to.") | ||
| 9361 | |||
| 9362 | This sets the variable save-completions-file-name to a value that | ||
| 9363 | depends on the operating system, because the definition of | ||
| 9364 | convert-standard-filename depends on the operating system. On | ||
| 9365 | Unix-like systems, it returns the specified file name unchanged. On | ||
| 9366 | MS-DOS, it adapts the name to fit the limitations of that system. | ||
| 9367 | |||
| 9368 | ** The interactive spec N now returns the numeric prefix argument | ||
| 9369 | rather than the raw prefix argument. (It still reads a number using the | ||
| 9370 | minibuffer if there is no prefix argument at all.) | ||
| 9371 | |||
| 9372 | ** When a process is deleted, this no longer disconnects the process | ||
| 9373 | marker from its buffer position. | ||
| 9374 | |||
| 9375 | ** The variable garbage-collection-messages now controls whether | ||
| 9376 | Emacs displays a message at the beginning and end of garbage collection. | ||
| 9377 | The default is nil, meaning there are no messages. | ||
| 9378 | |||
| 9379 | ** The variable debug-ignored-errors specifies certain kinds of errors | ||
| 9380 | that should not enter the debugger. Its value is a list of error | ||
| 9381 | condition symbols and/or regular expressions. If the error has any | ||
| 9382 | of the condition symbols listed, or if any of the regular expressions | ||
| 9383 | matches the error message, then that error does not enter the debugger, | ||
| 9384 | regardless of the value of debug-on-error. | ||
| 9385 | |||
| 9386 | This variable is initialized to match certain common but uninteresting | ||
| 9387 | errors that happen often during editing. | ||
| 9388 | |||
| 9389 | ** The new function error-message-string converts an error datum | ||
| 9390 | into its error message. The error datum is what condition-case | ||
| 9391 | puts into the variable, to describe the error that happened. | ||
| 9392 | |||
| 9393 | ** Anything that changes which buffer appears in a given window | ||
| 9394 | now runs the window-scroll-functions for that window. | ||
| 9395 | |||
| 9396 | ** The new function get-buffer-window-list returns a list of windows displaying | ||
| 9397 | a buffer. The function is called with the buffer (a buffer object or a buffer | ||
| 9398 | name) and two optional arguments specifying the minibuffer windows and frames | ||
| 9399 | to search. Therefore this function takes optional args like next-window etc., | ||
| 9400 | and not get-buffer-window. | ||
| 9401 | |||
| 9402 | ** buffer-substring now runs the hook buffer-access-fontify-functions, | ||
| 9403 | calling each function with two arguments--the range of the buffer | ||
| 9404 | being accessed. buffer-substring-no-properties does not call them. | ||
| 9405 | |||
| 9406 | If you use this feature, you should set the variable | ||
| 9407 | buffer-access-fontified-property to a non-nil symbol, which is a | ||
| 9408 | property name. Then, if all the characters in the buffer range have a | ||
| 9409 | non-nil value for that property, the buffer-access-fontify-functions | ||
| 9410 | are not called. When called, these functions should put a non-nil | ||
| 9411 | property on the text that they fontify, so that they won't get called | ||
| 9412 | over and over for the same text. | ||
| 9413 | |||
| 9414 | ** Changes in lisp-mnt.el | ||
| 9415 | |||
| 9416 | *** The lisp-mnt package can now recognize file headers that are written | ||
| 9417 | in the formats used by the `what' command and the RCS `ident' command: | ||
| 9418 | |||
| 9419 | ;; @(#) HEADER: text | ||
| 9420 | ;; $HEADER: text $ | ||
| 9421 | |||
| 9422 | in addition to the normal | ||
| 9423 | |||
| 9424 | ;; HEADER: text | ||
| 9425 | |||
| 9426 | *** The commands lm-verify and lm-synopsis are now interactive. lm-verify | ||
| 9427 | checks that the library file has proper sections and headers, and | ||
| 9428 | lm-synopsis extracts first line "synopsis'"information. | ||
| 9429 | |||
