@@ -8654,781 +8654,6 @@ An example of using this feature: if we define imenu items for the #include directives in a C file, we can open the included file when we select one of those items. -* Emacs 19.34 is a bug-fix release with no user-visible changes. - -* Changes in Emacs 19.33. - -** Bibtex mode no longer turns on Auto Fill automatically. (No major -mode should do that--it is the user's choice.) - -** The variable normal-auto-fill-function specifies the function to -use for auto-fill-function, if and when Auto Fill is turned on. -Major modes can set this locally to alter how Auto Fill works. - -* Editing Changes in Emacs 19.32 - -** C-x f with no argument now signals an error. -To set the fill column at the current column, use C-u C-x f. - -** Expanding dynamic abbrevs with M-/ is now smarter about case -conversion. If you type the abbreviation with mixed case, and it -matches the beginning of the expansion including case, then the -expansion is copied verbatim. Using SPC M-/ to copy an additional -word always copies it verbatim except when the previous copied word is -all caps. - -** On a non-windowing terminal, which can display only one Emacs frame -at a time, creating a new frame with C-x 5 2 also selects that frame. - -When using a display that can show multiple frames at once, C-x 5 2 -does make the frame visible, but does not select it. This is the same -as in previous Emacs versions. - -** You can use C-x 5 2 to create multiple frames on MSDOS, just as on a -non-X terminal on Unix. Of course, only one frame is visible at any -time, since your terminal doesn't have the ability to display multiple -frames. - -** On Windows, set win32-pass-alt-to-system to a non-nil value -if you would like tapping the Alt key to invoke the Windows menu. -This feature is not enabled by default; since the Alt key is also the -Meta key, it is too easy and painful to activate this feature by -accident. - -** The command apply-macro-to-region-lines repeats the last defined -keyboard macro once for each complete line within the current region. -It does this line by line, by moving point to the beginning of that -line and then executing the macro. - -This command is not new, but was never documented before. - -** You can now use Mouse-1 to place the region around a string constant -(something surrounded by doublequote characters or other delimiter -characters of like syntax) by double-clicking on one of the delimiting -characters. - -** Font Lock mode - -*** Font Lock support modes - -Font Lock can be configured to use Fast Lock mode and Lazy Lock mode (see -below) in a flexible way. Rather than adding the appropriate function to the -hook font-lock-mode-hook, you can use the new variable font-lock-support-mode -to control which modes have Fast Lock mode or Lazy Lock mode turned on when -Font Lock mode is enabled. - -For example, to use Fast Lock mode when Font Lock mode is turned on, put: - - (setq font-lock-support-mode 'fast-lock-mode) - -in your ~/.emacs. - -*** lazy-lock - -The lazy-lock package speeds up Font Lock mode by making fontification occur -only when necessary, such as when a previously unfontified part of the buffer -becomes visible in a window. When you create a buffer with Font Lock mode and -Lazy Lock mode turned on, the buffer is not fontified. When certain events -occur (such as scrolling), Lazy Lock makes sure that the visible parts of the -buffer are fontified. Lazy Lock also defers on-the-fly fontification until -Emacs has been idle for a given amount of time. - -To use this package, put in your ~/.emacs: - - (setq font-lock-support-mode 'lazy-lock-mode) - -To control the package behaviour, see the documentation for `lazy-lock-mode'. - -** Changes in BibTeX mode. - -*** For all entries allow spaces and tabs between opening brace or -paren and key. - -*** Non-escaped double-quoted characters (as in `Sch"of') are now -supported. - -** Gnus changes. - -Gnus, the Emacs news reader, has undergone further rewriting. Many new -commands and variables have been added. There should be no -significant incompatibilities between this Gnus version and the -previously released version, except in the message composition area. - -Below is a list of the more user-visible changes. Coding changes -between Gnus 5.1 and 5.2 are more extensive. - -*** A new message composition mode is used. All old customization -variables for mail-mode, rnews-reply-mode and gnus-msg are now -obsolete. - -*** Gnus is now able to generate "sparse" threads -- threads where -missing articles are represented by empty nodes. - - (setq gnus-build-sparse-threads 'some) - -*** Outgoing articles are stored on a special archive server. - - To disable this: (setq gnus-message-archive-group nil) - -*** Partial thread regeneration now happens when articles are -referred. - -*** Gnus can make use of GroupLens predictions: - - (setq gnus-use-grouplens t) - -*** A trn-line tree buffer can be displayed. - - (setq gnus-use-trees t) - -*** An nn-like pick-and-read minor mode is available for the summary -buffers. - - (add-hook 'gnus-summary-mode-hook 'gnus-pick-mode) - -*** In binary groups you can use a special binary minor mode: - - `M-x gnus-binary-mode' - -*** Groups can be grouped in a folding topic hierarchy. - - (add-hook 'gnus-group-mode-hook 'gnus-topic-mode) - -*** Gnus can re-send and bounce mail. - - Use the `S D r' and `S D b'. - -*** Groups can now have a score, and bubbling based on entry frequency -is possible. - - (add-hook 'gnus-summary-exit-hook 'gnus-summary-bubble-group) - -*** Groups can be process-marked, and commands can be performed on -groups of groups. - -*** Caching is possible in virtual groups. - -*** nndoc now understands all kinds of digests, mail boxes, rnews news -batches, ClariNet briefs collections, and just about everything else. - -*** Gnus has a new backend (nnsoup) to create/read SOUP packets. - -*** The Gnus cache is much faster. - -*** Groups can be sorted according to many criteria. - - For instance: (setq gnus-group-sort-function 'gnus-group-sort-by-rank) - -*** New group parameters have been introduced to set list-address and -expiration times. - -*** All formatting specs allow specifying faces to be used. - -*** There are several more commands for setting/removing/acting on -process marked articles on the `M P' submap. - -*** The summary buffer can be limited to show parts of the available -articles based on a wide range of criteria. These commands have been -bound to keys on the `/' submap. - -*** Articles can be made persistent -- as an alternative to saving -articles with the `*' command. - -*** All functions for hiding article elements are now toggles. - -*** Article headers can be buttonized. - - (add-hook 'gnus-article-display-hook 'gnus-article-add-buttons-to-head) - -*** All mail backends support fetching articles by Message-ID. - -*** Duplicate mail can now be treated properly. See the -`nnmail-treat-duplicates' variable. - -*** All summary mode commands are available directly from the article -buffer. - -*** Frames can be part of `gnus-buffer-configuration'. - -*** Mail can be re-scanned by a daemonic process. - -*** Gnus can make use of NoCeM files to filter spam. - - (setq gnus-use-nocem t) - -*** Groups can be made permanently visible. - - (setq gnus-permanently-visible-groups "^nnml:") - -*** Many new hooks have been introduced to make customizing easier. - -*** Gnus respects the Mail-Copies-To header. - -*** Threads can be gathered by looking at the References header. - - (setq gnus-summary-thread-gathering-function - 'gnus-gather-threads-by-references) - -*** Read articles can be stored in a special backlog buffer to avoid -refetching. - - (setq gnus-keep-backlog 50) - -*** A clean copy of the current article is always stored in a separate -buffer to allow easier treatment. - -*** Gnus can suggest where to save articles. See `gnus-split-methods'. - -*** Gnus doesn't have to do as much prompting when saving. - - (setq gnus-prompt-before-saving t) - -*** gnus-uu can view decoded files asynchronously while fetching -articles. - - (setq gnus-uu-grabbed-file-functions 'gnus-uu-grab-view) - -*** Filling in the article buffer now works properly on cited text. - -*** Hiding cited text adds buttons to toggle hiding, and how much -cited text to hide is now customizable. - - (setq gnus-cited-lines-visible 2) - -*** Boring headers can be hidden. - - (add-hook 'gnus-article-display-hook 'gnus-article-hide-boring-headers) - -*** Default scoring values can now be set from the menu bar. - -*** Further syntax checking of outgoing articles have been added. - -The Gnus manual has been expanded. It explains all these new features -in greater detail. - -* Lisp Changes in Emacs 19.32 - -** The function set-visited-file-name now accepts an optional -second argument NO-QUERY. If it is non-nil, then the user is not -asked for confirmation in the case where the specified file already -exists. - -** The variable print-length applies to printing vectors and bitvectors, -as well as lists. - -** The new function keymap-parent returns the parent keymap -of a given keymap. - -** The new function set-keymap-parent specifies a new parent for a -given keymap. The arguments are KEYMAP and PARENT. PARENT must be a -keymap or nil. - -** Sometimes menu keymaps use a command name, a symbol, which is really -an automatically generated alias for some other command, the "real" -name. In such a case, you should give that alias symbol a non-nil -menu-alias property. That property tells the menu system to look for -equivalent keys for the real name instead of equivalent keys for the -alias. - -* Editing Changes in Emacs 19.31 - -** Freedom of the press restricted in the United States. - -Emacs has been censored in accord with the Communications Decency Act. -This includes removing some features of the doctor program. That law -was described by its supporters as a ban on pornography, but it bans -far more than that. The Emacs distribution has never contained any -pornography, but parts of it were nonetheless prohibited. - -For information on US government censorship of the Internet, and what -you can do to bring back freedom of the press, see the web site -`http://www.vtw.org/'. - -** A note about C mode indentation customization. - -The old (Emacs 19.29) ways of specifying a C indentation style -do not normally work in the new implementation of C mode. -It has its own methods of customizing indentation, which are -much more powerful than the old C mode. See the Editing Programs -chapter of the manual for details. - -However, you can load the library cc-compat to make the old -customization variables take effect. - -** Marking with the mouse. - -When you mark a region with the mouse, the region now remains -highlighted until the next input event, regardless of whether you are -using M-x transient-mark-mode. - -** Improved Windows NT/95 support. - -*** Emacs now supports scroll bars on Windows NT and Windows 95. - -*** Emacs now supports subprocesses on Windows 95. (Subprocesses used -to work on NT only and not on 95.) - -*** There are difficulties with subprocesses, though, due to problems -in Windows, beyond the control of Emacs. They work fine as long as -you run Windows applications. The problems arise when you run a DOS -application in a subprocesses. Since current shells run as DOS -applications, these problems are significant. - -If you run a DOS application in a subprocess, then the application is -likely to busy-wait, which means that your machine will be 100% busy. -However, if you don't mind the temporary heavy load, the subprocess -will work OK as long as you tell it to terminate before you start any -other DOS application as a subprocess. - -Emacs is unable to terminate or interrupt a DOS subprocess. -You have to do this by providing input directly to the subprocess. - -If you run two DOS applications at the same time in two separate -subprocesses, even if one of them is asynchronous, you will probably -have to reboot your machine--until then, it will remain 100% busy. -Windows simply does not cope when one Windows process tries to run two -separate DOS subprocesses. Typing CTL-ALT-DEL and then choosing -Shutdown seems to work although it may take a few minutes. - -** M-x resize-minibuffer-mode. - -This command, not previously mentioned in NEWS, toggles a mode in -which the minibuffer window expands to show as many lines as the -minibuffer contains. - -** `title' frame parameter and resource. - -The `title' X resource now specifies just the frame title, nothing else. -It does not affect the name used for looking up other X resources. -It works by setting the new `title' frame parameter, which likewise -affects just the displayed title of the frame. - -The `name' parameter continues to do what it used to do: -it specifies the frame name for looking up X resources, -and also serves as the default for the displayed title -when the `title' parameter is unspecified or nil. - -** Emacs now uses the X toolkit by default, if you have a new -enough version of X installed (X11R5 or newer). - -** When you compile Emacs with the Motif widget set, Motif handles the -F10 key by activating the menu bar. To avoid confusion, the usual -Emacs binding of F10 is replaced with a no-op when using Motif. - -If you want to be able to use F10 in Emacs, you can rebind the Motif -menubar to some other key which you don't use. To do so, add -something like this to your X resources file. This example rebinds -the Motif menu bar activation key to S-F12: - - Emacs*defaultVirtualBindings: osfMenuBar : Shift<Key>F12 - -** In overwrite mode, DEL now inserts spaces in most cases -to replace the characters it "deletes". - -** The Rmail summary now shows the number of lines in each message. - -** Rmail has a new command M-x unforward-rmail-message, which extracts -a forwarded message from the message that forwarded it. To use it, -select a message which contains a forwarded message and then type the command. -It inserts the forwarded message as a separate Rmail message -immediately after the selected one. - -This command also undoes the textual modifications that are standardly -made, as part of forwarding, by Rmail and other mail reader programs. - -** Turning off saving of .saves-... files in your home directory. - -Each Emacs session writes a file named .saves-... in your home -directory to record which files M-x recover-session should recover. -If you exit Emacs normally with C-x C-c, it deletes that file. If -Emacs or the operating system crashes, the file remains for M-x -recover-session. - -You can turn off the writing of these files by setting -auto-save-list-file-name to nil. If you do this, M-x recover-session -will not work. - -Some previous Emacs versions failed to delete these files even on -normal exit. This is fixed now. If you are thinking of turning off -this feature because of past experiences with versions that had this -bug, it would make sense to check whether you still want to do so -now that the bug is fixed. - -** Changes to Version Control (VC) - -There is a new variable, vc-follow-symlinks. It indicates what to do -when you visit a link to a file that is under version control. -Editing the file through the link bypasses the version control system, -which is dangerous and probably not what you want. - -If this variable is t, VC follows the link and visits the real file, -telling you about it in the echo area. If it is `ask' (the default), -VC asks for confirmation whether it should follow the link. If nil, -the link is visited and a warning displayed. - -** iso-acc.el now lets you specify a choice of language. -Languages include "latin-1" (the default) and "latin-2" (which -is designed for entering ISO Latin-2 characters). - -There are also choices for specific human languages such as French and -Portuguese. These are subsets of Latin-1, which differ in that they -enable only the accent characters needed for particular language. -The other accent characters, not needed for the chosen language, -remain normal. - -** Posting articles and sending mail now has M-TAB completion on various -header fields (Newsgroups, To, CC, ...). - -Completion in the Newsgroups header depends on the list of groups -known to your news reader. Completion in the Followup-To header -offers those groups which are in the Newsgroups header, since -Followup-To usually just holds one of those. - -Completion in fields that hold mail addresses works based on the list -of local users plus your aliases. Additionally, if your site provides -a mail directory or a specific host to use for any unrecognized user -name, you can arrange to query that host for completion also. (See the -documentation of variables `mail-directory-process' and -`mail-directory-stream'.) - -** A greatly extended sgml-mode offers new features such as (to be configured) -skeletons with completing read for tags and attributes, typing named -characters including optionally all 8bit characters, making tags invisible -with optional alternate display text, skipping and deleting tag(pair)s. - -Note: since Emacs' syntax feature cannot limit the special meaning of ', " and -- to inside <>, for some texts the result, especially of font locking, may be -wrong (see `sgml-specials' if you get wrong results). - -The derived html-mode configures this with tags and attributes more or -less HTML3ish. It also offers optional quick keys like C-c 1 for -headline or C-c u for unordered list (see `html-quick-keys'). Edit / -Text Properties / Face or M-g combinations create tags as applicable. -Outline minor mode is supported and level 1 font-locking tries to -fontify tag contents (which only works when they fit on one line, due -to a limitation in font-lock). - -External viewing via browse-url can occur automatically upon saving. - -** M-x imenu-add-to-menubar now adds to the menu bar for the current -buffer only. If you want to put an Imenu item in the menu bar for all -buffers that use a particular major mode, use the mode hook, as in -this example: - - (add-hook 'emacs-lisp-mode-hook - '(lambda () (imenu-add-to-menubar "Index"))) - -** Changes in BibTeX mode. - -*** Field names may now contain digits, hyphens, and underscores. - -*** Font Lock mode is now supported. - -*** bibtex-make-optional-field is no longer interactive. - -*** If bibtex-maintain-sorted-entries is non-nil, inserting new -entries is now done with a faster algorithm. However, inserting -will fail in this case if the buffer contains invalid entries or -isn't in sorted order, so you should finish each entry with C-c C-c -(bibtex-close-entry) after you have inserted or modified it. -The default value of bibtex-maintain-sorted-entries is nil. - -*** Function `show-all' is no longer bound to a key, since C-u C-c C-q -does the same job. - -*** Entries with quotes inside quote-delimited fields (as `author = -"Stefan Sch{\"o}f"') are now supported. - -*** Case in field names doesn't matter anymore when searching for help -text. - -** Font Lock mode - -*** Global Font Lock mode - -Font Lock mode can be turned on globally, in buffers that support it, by the -new command global-font-lock-mode. You can use the new variable -font-lock-global-modes to control which modes have Font Lock mode automagically -turned on. By default, this variable is set so that Font Lock mode is turned -on globally where the buffer mode supports it. - -For example, to automagically turn on Font Lock mode where supported, put: - - (global-font-lock-mode t) - -in your ~/.emacs. - -*** Local Refontification - -In Font Lock mode, editing a line automatically refontifies that line only. -However, if your change alters the syntactic context for following lines, -those lines remain incorrectly fontified. To refontify them, use the new -command M-g M-g (font-lock-fontify-block). - -In certain major modes, M-g M-g refontifies the entire current function. -(The variable font-lock-mark-block-function controls how to find the -current function.) In other major modes, M-g M-g refontifies 16 lines -above and below point. - -With a prefix argument N, M-g M-g refontifies N lines above and below point. - -** Follow mode - -Follow mode is a new minor mode combining windows showing the same -buffer into one tall "virtual window". The windows are typically two -side-by-side windows. Follow mode makes them scroll together as if -they were a unit. To use it, go to a frame with just one window, -split it into two side-by-side windows using C-x 3, and then type M-x -follow-mode. - -M-x follow-mode turns off Follow mode if it is already enabled. - -To display two side-by-side windows and activate Follow mode, use the -command M-x follow-delete-other-windows-and-split. - -** hide-show changes. - -The hooks hs-hide-hooks and hs-show-hooks have been renamed -to hs-hide-hook and hs-show-hook, to follow the convention for -normal hooks. - -** Simula mode now has a menu containing the most important commands. -The new command simula-indent-exp is bound to C-M-q. - -** etags can now handle programs written in Erlang. Files are -recognised by the extensions .erl and .hrl. The tagged lines are -those that begin a function, record, or macro. - -** MSDOS Changes - -*** It is now possible to compile Emacs with the version 2 of DJGPP. -Compilation with DJGPP version 1 also still works. - -*** The documentation of DOS-specific aspects of Emacs was rewritten -and expanded; see the ``MS-DOS'' node in the on-line docs. - -*** Emacs now uses ~ for backup file names, not .bak. - -*** You can simulate mouse-3 on two-button mice by simultaneously -pressing both mouse buttons. - -*** A number of packages and commands which previously failed or had -restricted functionality on MS-DOS, now work. The most important ones -are: - -**** Printing (both with `M-x lpr-buffer' and with `ps-print' package) -now works. - -**** `Ediff' works (in a single-frame mode). - -**** `M-x display-time' can be used on MS-DOS (due to the new -implementation of Emacs timers, see below). - -**** `Dired' supports Unix-style shell wildcards. - -**** The `c-macro-expand' command now works as on other platforms. - -**** `M-x recover-session' works. - -**** `M-x list-colors-display' displays all the available colors. - -**** The `TPU-EDT' package works. - -* Lisp changes in Emacs 19.31. - -** The function using-unix-filesystems on Windows NT and Windows 95 -tells Emacs to read and write files assuming that they reside on a -remote Unix filesystem. No CR/LF translation is done on any files in -this case. Invoking using-unix-filesystems with t activates this -behavior, and invoking it with any other value deactivates it. - -** Change in system-type and system-configuration values. - -The value of system-type on a Linux-based GNU system is now `lignux', -not `linux'. This means that some programs which use `system-type' -need to be changed. The value of `system-configuration' will also -be different. - -It is generally recommended to use `system-configuration' rather -than `system-type'. - -See the file LINUX-GNU in this directory for more about this. - -** The functions shell-command and dired-call-process -now run file name handlers for default-directory, if it has them. - -** Undoing the deletion of text now restores the positions of markers -that pointed into or next to the deleted text. - -** Timers created with run-at-time now work internally to Emacs, and -no longer use a separate process. Therefore, they now work more -reliably and can be used for shorter time delays. - -The new function run-with-timer is a convenient way to set up a timer -to run a specified amount of time after the present. A call looks -like this: - - (run-with-timer SECS REPEAT FUNCTION ARGS...) - -SECS says how many seconds should elapse before the timer happens. -It may be an integer or a floating point number. When the timer -becomes ripe, the action is to call FUNCTION with arguments ARGS. - -REPEAT gives the interval for repeating the timer (measured in -seconds). It may be an integer or a floating point number. nil or 0 -means don't repeat at all--call FUNCTION just once. - -*** with-timeout provides an easy way to do something but give -up if too much time passes. - - (with-timeout (SECONDS TIMEOUT-FORMS...) BODY...) - -This executes BODY, but gives up after SECONDS seconds. -If it gives up, it runs the TIMEOUT-FORMS and returns the value -of the last one of them. Normally it returns the value of the last -form in BODY. - -*** You can now arrange to call a function whenever Emacs is idle for -a certain length of time. To do this, call run-with-idle-timer. A -call looks like this: - - (run-with-idle-timer SECS REPEAT FUNCTION ARGS...) - -SECS says how many seconds of idleness should elapse before the timer -runs. It may be an integer or a floating point number. When the -timer becomes ripe, the action is to call FUNCTION with arguments -ARGS. - -Emacs becomes idle whenever it finishes executing a keyboard or mouse -command. It remains idle until it receives another keyboard or mouse -command. - -REPEAT, if non-nil, means this timer should be activated again each -time Emacs becomes idle and remains idle for SECS seconds The timer -does not repeat if Emacs *remains* idle; it runs at most once after -each time Emacs becomes idle. - -If REPEAT is nil, the timer runs just once, the first time Emacs is -idle for SECS seconds. - -*** post-command-idle-hook is now obsolete; you shouldn't use it at -all, because it interferes with the idle timer mechanism. If your -programs use post-command-idle-hook, convert them to use idle timers -instead. - -*** y-or-n-p-with-timeout lets you ask a question but give up if -there is no answer within a certain time. - - (y-or-n-p-with-timeout PROMPT SECONDS DEFAULT-VALUE) - -asks the question PROMPT (just like y-or-n-p). If the user answers -within SECONDS seconds, it returns the answer that the user gave. -Otherwise it gives up after SECONDS seconds, and returns DEFAULT-VALUE. - -** Minor change to `encode-time': you can now pass more than seven -arguments. If you do that, the first six arguments have the usual -meaning, the last argument is interpreted as the time zone, and the -arguments in between are ignored. - -This means that it works to use the list returned by `decode-time' as -the list of arguments for `encode-time'. - -** The default value of load-path now includes the directory -/usr/local/share/emacs/VERSION/site-lisp In addition to -/usr/local/share/emacs/site-lisp. You can use this new directory for -site-specific Lisp packages that belong with a particular Emacs -version. - -It is not unusual for a Lisp package that works well in one Emacs -version to cause trouble in another. Sometimes packages need updating -for incompatible changes; sometimes they look at internal data that -has changed; sometimes the package has been installed in Emacs itself -and the installed version should be used. Whatever the reason for the -problem, this new feature makes it easier to solve. - -** When your program contains a fixed file name (like .completions or -.abbrev.defs), the file name usually needs to be different on operating -systems with limited file name syntax. - -Now you can avoid ad-hoc conditionals by using the function -convert-standard-filename to convert the file name to a proper form -for each operating system. Here is an example of use, from the file -completions.el: - -(defvar save-completions-file-name - (convert-standard-filename "~/.completions") - "*The filename to save completions to.") - -This sets the variable save-completions-file-name to a value that -depends on the operating system, because the definition of -convert-standard-filename depends on the operating system. On -Unix-like systems, it returns the specified file name unchanged. On -MS-DOS, it adapts the name to fit the limitations of that system. - -** The interactive spec N now returns the numeric prefix argument -rather than the raw prefix argument. (It still reads a number using the -minibuffer if there is no prefix argument at all.) - -** When a process is deleted, this no longer disconnects the process -marker from its buffer position. - -** The variable garbage-collection-messages now controls whether -Emacs displays a message at the beginning and end of garbage collection. -The default is nil, meaning there are no messages. - -** The variable debug-ignored-errors specifies certain kinds of errors -that should not enter the debugger. Its value is a list of error -condition symbols and/or regular expressions. If the error has any -of the condition symbols listed, or if any of the regular expressions -matches the error message, then that error does not enter the debugger, -regardless of the value of debug-on-error. - -This variable is initialized to match certain common but uninteresting -errors that happen often during editing. - -** The new function error-message-string converts an error datum -into its error message. The error datum is what condition-case -puts into the variable, to describe the error that happened. - -** Anything that changes which buffer appears in a given window -now runs the window-scroll-functions for that window. - -** The new function get-buffer-window-list returns a list of windows displaying -a buffer. The function is called with the buffer (a buffer object or a buffer -name) and two optional arguments specifying the minibuffer windows and frames -to search. Therefore this function takes optional args like next-window etc., -and not get-buffer-window. - -** buffer-substring now runs the hook buffer-access-fontify-functions, -calling each function with two arguments--the range of the buffer -being accessed. buffer-substring-no-properties does not call them. - -If you use this feature, you should set the variable -buffer-access-fontified-property to a non-nil symbol, which is a -property name. Then, if all the characters in the buffer range have a -non-nil value for that property, the buffer-access-fontify-functions -are not called. When called, these functions should put a non-nil -property on the text that they fontify, so that they won't get called -over and over for the same text. - -** Changes in lisp-mnt.el - -*** The lisp-mnt package can now recognize file headers that are written -in the formats used by the `what' command and the RCS `ident' command: - -;; @(#) HEADER: text -;; $HEADER: text $ - -in addition to the normal - -;; HEADER: text - -*** The commands lm-verify and lm-synopsis are now interactive. lm-verify -checks that the library file has proper sections and headers, and -lm-synopsis extracts first line "synopsis'"information. - - - * For older news, see the file ONEWS ---------------------------------------------------------------------- |
