The - ASCII code this sends will generally be the value that would be sent by - pressing just "a" minus 96 or 64. Either way it will be a number from 0 - to 31. - - M-a means press the "a" key while holding down the "Meta" key. The - ASCII code this sends is the sum of the ASCII code that would be sent by - pressing just "a" and 128. - - M-C-a means press the "a" key while holding down both the "Control" key - and the "Meta" key. C-M-a is a synonym for M-C-a. - - * RET means press the "Return" key. RET is the same as C-m. This sends - ASCII code 13. - * LFD means press the "Linefeed" key. LFD is also the same as C-j. This - sends ASCII code 10. Under Unix, ASCII code 10 is more often called - "Newline". - * DEL means press the "Delete" key. DEL is the same as C-?. This sends - ASCII code 127. (WARNING: It is a misnomer to call C-? a "control" key, - since 127 has both bits 6 and 7 turned ON, and the rule for control keys - is that they have 6 and 7 turned OFF. Also, on very few keyboards does - Control-? generate ASCII code 127. In fact, Control-? (which is - actually Control-Shift-/) is more likely to generate C-_, ASCII code - 31!) - * ESC means press the "Escape" key. ESC is the same as C-[. This sends - ASCII code 27. - * SPC means press the "Space" key. This send ASCII code 32. - * TAB means press the "Tab" key. TAB is the same as C-i. This send ASCII - code 9. - - For C-@ and C-^, usually you don't have to hold down the shift key and you - can type Control-2 or Control-6 instead. For C-_, you may have to hold - down the shift key, typing Control-Shift-Hyphen. C-@ can often be - generated by typing Control-Space. C-@ is often called the NUL character, - and has ASCII value 0. C-_ can often be generated by typing Control-7 or - Control-/. C-? (aka DEL) may be generated by typing Shift-BackSpace or + - Control-BackSpace. Try Control with all of the digits on your keyboard to + - see what gets generated. - - To read more about this online, type "C-h i m emacs RET m characters - RET", and also "C-h i m emacs RET m keys RET". - -2: What do you mean when you write things like this: type "ESC a"? - - I will enclose key sequences that are longer than one key inside double - quotes. These notations refer to single key strokes (some with - modifiers): - - C-x, M-x, M-C-x - RET, LFD, DEL, ESC, SPC, TAB - - I separate these from other keys within double quotes by spaces. Any - real spaces that I write inside double quotes can be ignored, only SPC - means press the space key. All other characters within double quotes - represent single keys (some shifted). - -3: What if I don't have a Meta key? +51: Is there an equivalent to the `.'

In fact, Emacs - converts M-a internally into "ESC a" anyway (depending on the value of - meta-prefix-char). +1: What do these mean: C-h, M-C-a, RET, "ESC a", etc.? -4: What if I don't have an Escape key? + C-x means press the `x' key while holding down the Control key. M-x means + press the `x' key while holding down the Meta key. M-C-x means press the + `x' key while holding down both the Control key and the Meta key. C-M-a + is a synonym for M-C-a. RET, LFD, DEL, ESC, and TAB respectively refer to + pressing the Return, Linefeed (aka Newline), Delete, Escape, and Tab keys + and are equivalent to C-m, C-j, C-?, C-[, and C-i. SPC means press the + Space bar. - Type C-[ instead. This should send ASCII code 27 just like an Escape - key would. + I put any key sequence that is longer than one key (and some single-key + sequences) inside double quotes or on a line by itself. Any real spaces + in such a key sequence should be ignored; only SPC really means press the + space key. + + The ASCII code sent by C-x (except for C-?) is the value that would be + sent by pressing just `x' minus 96 (or 64 for uppercase `X') and will be + from 0 to 31. The ASCII code sent by M-x is the sum of 128 and the ASCII + code that would be sent by pressing just the `x' key. Essentially, the + Control key turns off bits 5 and 6 and the Meta key turns on bit 7. -5: What does "M-x command" mean? + For further information, see `Characters' and `Keys' in the online manual. + + NOTE: C-?

Also, on very + few keyboards does Control-? generate ASCII code 127. + +2: What does "M-x command" mean? "M-x command" means type M-x, then type the name of the command, then type RET. - M-x is simply the default key sequence that invokes the command - "execute-extended-command". This command allows you to run any Emacs - command if you can remember the command's name. If you can't remember - the command's name, you can type TAB and SPC for completion, and ? for a - list of possibilities. An Emacs "command" is any "interactive" Emacs - function. + M-x (by default) invokes the command `execute-extended-command'. This + command allows you to run any Emacs command if you can remember the + command's name. If you can't remember the command's name, you can type + TAB and SPC for completion, and "?" for a list of possibilities. An Emacs + "command" is any "interactive" Emacs function. NOTE: Your system administrator may have bound other key sequences to - invoke execute-extended-command. A function key labeled "Do" is a good + invoke execute-extended-command. A function key labeled `Do' is a good candidate for this. - To run non-interactive Emacs functions, use M-ESC instead and type a - Lisp form that invokes the function (see question 102). + To run non-interactive Emacs functions, see question 53. + +3: How do I read topic XXX in the on-line manual? + + When I refer you to topic XXX in the on-line manual, you can read this + manual node inside Emacs (assuming nothing is broken) by typing this: + + C-h i m emacs RET m XXX RET + + This invokes the Info facility.

This + includes GNU Emacs along with various other implementations like JOVE, + MicroEmacs, Freemacs, MG, Unipress, CCA, Epsilon, etc. + + Many people post GNU Emacs questions to comp.emacs because they don't + receive any of the gnu.* newsgroups.

Be careful to remove the gnu.* + groups from the `Newsgroups:' line when posting a followup that recommends + such software. + + gnu.emacs.bug is a place where bug reports appear, but avoid posting bug + reports to this newsgroup, instead see question 10. + +9: Where can I get old postings to gnu.emacs.help and other GNU groups? + + The FSF has maintained archives of all of the GNU mailing lists for many + years, although there may be some unintentional gaps in coverage.

This - includes GNU Emacs along with various other implementations like JOVE, - MicroEmacs, Freemacs, MG, Unipress, CCA, Epsilon, etc. + Emacs originally was an acronym for Editor MACroS. RMS says he "picked + the name `Emacs' because `E' was not in use as an abbreviation on ITS at + the time.". The first Emacs was a set of macros written in 1976 at MIT by + RMS for the editor TECO (Text Editor and COrrector (originally Tape Editor + and COrrector)) under ITS on a PDP-10. RMS had already extended TECO with + a "real-time" full screen mode with active keys. Emacs was started by Guy + Steele <gls@think.com> as a project to unify the many divergent TECO + command sets and keybindings at MIT. - Many people post GNU Emacs questions to comp.emacs because they don't - receive any of the gnu.* newsgroups. Arguments have been made both for - and against posting GNU-Emacs-specific material to comp.emacs. You have - to decide for yourself. + Many people have told me that TECO code looks a lot like line noise. See + alt.lang.teco if you are interested. I think someone has written a TECO + implementation in Emacs Lisp. It would be an interesting project to run + the original TECO Emacs inside of GNU Emacs. - Messages advocating "non-free" software are considered unacceptable on any - of the gnu.* newsgroups except for gnu.misc.discuss, which was created to - hold the extensive flame-wars on the subject. "non-free" software - includes any software for which the end user can't get source code. Be - careful to remove the gnu.* groups from the "Newsgroups:" line when - posting a followup that recommends such software. +24: What is the latest version of GNU Emacs? - The correct place to report GNU Emacs bugs is by e-mail to - bug-gnu-emacs@prep.ai.mit.edu. Anything sent here also appears in the - newsgroup gnu.emacs.bug, but please use e-mail instead of news to submit - the bug report. This way a reliable return address is available so you - can be contacted for further details. + GNU Emacs 18.59 is the current version. Fixes from 18.57 include better ! + mail address parsing, an X visual bell speedup, a call-process + enhancement, a regexp matching change, the ability to apply a numeric + argument to a self-inserting digit, getting X resource values from the + RESOURCE_MANAGER property, more reliable shell mode job control, and a + change to copy-keymap. Also, support has been added for many new system + types. Fixes from 18.55 include the removal of arbitrary limits on the + undo facility. - RMS explains: ! + According to the January 1992 GNU's Bulletin, "Emacs 18 maintenance + continues for simple bug fixes.". - Sending bug reports to help-gnu-emacs (which has the effect of posting - on gnu.emacs.help) is undesirable because it takes the time of an - unnecessarily large group of people, most of whom are just users and - have no idea how to fix these problem. bug-gnu-emacs reaches a much - smaller group of people who are more likely to know what to do and have - expressed a wish to receive more messages about Emacs than the others. + To visit a file with information about what has changed in recent + versions, type "C-h n". + +25: When will GNU Emacs 19 be available? + + There are strong indications that Emacs 19 will be available in 1992. The + FSF has recently gone through a spate of copyright disclaimer checking, + which is a good sign. + + Lucid has released Lucid GNU Emacs 19.3, which is based on an early ! + unreleased version of GNU Emacs 19. This will be similar to Emacs 19 when + it finally arrives, but they are not the same. See question 121. + + Work has begun on features for Emacs 20. + +26: What is different about GNU Emacs 19? + + From the January 1992 GNU's Bulletin: + + Version 19 will enter beta test late this year. Among its new features + are: before and after change hooks, source-level debugging of Emacs Lisp + programs, X selection processing (including clipboard selections), + scrollbars, support for European character sets, floating point numbers, + per-buffer mouse commands, X resource manager interfacing, + mouse-tracking, Lisp-level binding of function keys, multiple X windows + (`screens' to Emacs), a new input system, and buffer allocation, which + uses a new mechanism capable of returning storage to the system when a + buffer is killed. + + The input stream is now a sequence of Lisp objects, instead of a + sequence of characters. This allows a reasonable representation for + mouse clicks, function keys, menu selections, etc. + + Thanks go to Alan Carroll and the people who worked on Epoch for + generating initial feedback to a multi-windowed Emacs, and to Eric + Raymond for help in polishing the Emacs 19 Lisp libraries. + + The June 1991 GNU's bulletin had this to say about future plans for Emacs: + + Features being considered for later releases of Emacs include: + associating property lists with regions of text in a buffer; multiple + fonts, color, and pixmaps defined by those properties; different + visibility conditions for the regions, and for various windows showing + one buffer; hooks to be run if point or mouse moves outside a certain + range; incrementally saving undo history in a file; static menu bars; + and better pop-up menus. + + Mention of this feature disappeared in the January 1992 GNU's bulletin: + + Emacs 19 supports two styles of multiple windows, one with a separate + screen for the minibuffer, and another with a minibuffer attached to + each screen. + + Mention of these two proposed features disappeared in the January 1991 + GNU's bulletin: + + * Incremental syntax analysis for various programming languages (Leif). + * A more sophisticated emacsclient/server model, which would provide + network transparent Emacs widget functionality. + +27: What variants of GNU Emacs exist? + + * Nemacs (Nihongo Emacs), which can handle Japanese text, is derived from + GNU Emacs 18.55. See question 149. + + * Demacs, which can run under MS-DOS on 386 machines, is derived from + Nemacs.

(This assumes the value of + search-quote-char is 17 (ie., C-q).) Searching for ALL unprintable + characters is best done with a "regexp" search. The easiest regexp to use + for the unprintable chars is the complement of the regexp for the + printable chars. + + Regexp for the printable chars: [\t\n\r\f -~] + + Regexp for the unprintable chars: [^\t\n\r\f -~] + + To type some of these special characters in an interactive argument to + isearch-forward-regexp or re-search-forward, you need to use C-q. (`\t', + `\n', `\r', and `\f' stand respectively for TAB, LFD, RET, and C-l.) So, + to search for unprintable characters using re-search-forward: + + M-x re-search-forward RET [^ TAB C-q LFD C-q RET C-q C-l SPC -~] RET + + Using isearch-forward-regexp: + + M-C-s [^ TAB RET C-q RET C-q C-l SPC -~] + + To delete all unprintable characters, simply use a replace-regexp: + + M-x replace-regexp RET [^ TAB C-q LFD C-q RET C-q C-l SPC -~] RET RET + + Replacing is similar to the above. {I need to write the text for this + part of the answer!} + + Notes: + + * With isearch, you can type RET to get a quoted LFD (not a quoted RET). + + * You don't need to quote TAB with either isearch or typing something in + the minibuffer. + + Here are the Emacs Lisp forms of the above regexps: + + ;; regexp matching all printable characters: + "[\t\n\r\f -~]" + + ;; regexp matching all unprintable characters: + "[^\t\n\r\f -~]" + +35: How can I highlight a region of text in Emacs? + + There are ways to get highlighting (reverse video, inverse video) in GNU + Emacs 18.59, but either they require patching the C code of Emacs and ! + rebuilding, or they are slow and the highlighting disappears if you scroll + or redraw the screen and it can not follow the point. Howard Gayle's + patches for 8-bit output appear to allow highlighting (see question + ^8-bit-output). Another patch for highlighting is by Kenichi Handa + <handa@etl.go.jp>. There is a patch for use with X by Andy Norman + <ange@hplb.hpl.hp.com> (and modified for 18.57 by Matthieu Herrb + <matthieu@laas.fr>), which is available for FTP: + + /laas.laas.fr:pub/emacs/patch-X11-18.55 ! + /laas.laas.fr:pub/emacs/patch-X11-18.57 ! + + You can highlight regions in a variety of ways in Epoch and Lucid Emacs. + GNU Emacs 19 may not be able to just temporarily highlight a region. + + Similar comments apply to displaying text in different fonts, except that + it is even harder. + +36: How do I control Emacs's case-sensitivity when searching/replacing? + + For searching, the value of the variable case-fold-search determines + whether they are case sensitive: + + (setq case-fold-search nil) ; make searches case sensitive + (setq case-fold-search t) ; make searches case insensitive + + Similarly, for replacing the variable case-replace determines whether + replacements preserve case. + + To change the case sensitivity just for one major mode, use the major + mode's hook. For example: + + (setq XXX-mode-hook + (function + (lambda () + (setq case-fold-search nil)))) + +37: How do I make Emacs wrap words for me? + + M-x auto-fill-mode. The default maximum line width is 74, determined by + the variable fill-column. To find how to turn this on automatically see + question 32. + +38: Where can I get a better spelling checker for Emacs? + + Use Ispell. See question 119. + +39: How can I spell-check TeX or *roff documents? + + If you want to spell-check TeX or *roff documents with Ispell, you need to + arrange for a filter program that understands how to strip TeX or *roff + formatting commands to be run. In the TeX distribution, there are several + different programs named `detex', all with incompatible options, and a + very old pair of programs named `detex' and `delatex', which should + probably be avoided. The most useful one for Ispell is `detex' by Daniel + Trinkle. A more recent version is available via FTP: + + /arthur.cs.purdue.edu:pub/trinkle/detex-2.4.tar ! + + Raphael Cerf <cerf@clipper.ens.fr> recently released a program for this + named `xetal': + + /spi.ens.fr:pub/unix/tex/ + + There is a program that comes with Unix named `deroff' for stripping + formatting commands from *roff files. + + Here is an example of code you can put in a .emacs file to use these + programs: + + ;; Based on suggestions by David G. Grubbs <dgg@ksr.com> and Paul Palmer + ;; <palmerp@math.orst.edu>. + + ;; Assuming the use of detex 2.3 by Daniel Trinkle: + ;; -w means one word per line. + ;; -n means don't expand \input or \include commands. + ;; -l means force LaTeX mode. + + (require 'ispell) ; for the make-variable-buffer-local statements + (setq plain-TeX-mode-hook + (function + (lambda () + (setq ispell-filter-hook "detex") + (setq ispell-filter-hook-args '("-nw"))))) + (setq LaTeX-mode-hook + (function + (lambda () + (setq ispell-filter-hook "detex") + (setq ispell-filter-hook-args '("-lnw"))))) + (setq nroff-mode-hook + (function + (lambda () + (setq ispell-filter-hook "deroff") + (setq ispell-filter-hook-args '("-w"))))) + + You will have to adjust the arguments for programs other than Trinkle's + detex or for other versions of deroff. Experiment running the command + from the shell to find the correct options. If you don't have a filter + that knows how to output one word per line, you must pipe its output + through another filter to break up the output. + +40: How do I change load-path? + + In general, you should only *add* to the load-path. You can add + directory /XXX/YYY to the load path like this: + + (setq load-path (append load-path '("/XXX/YYY/"))) + + To do this relative to your home directory: + + (setq load-path (append load-path (list (expand-file-name "~/YYY/")))) + +41: How do I use an already running Emacs from another window? + + The `emacsclient' program is for editing a file using an already running + Emacs rather than starting up a new Emacs. It does this by sending a + request to the already running Emacs, which must be expecting the request. + + * Setup + + Emacs must have executed the `server-start' function for emacsclient to + work. This can be done either by a command line option: + + emacs -f server-start + + or by invoking server-start from the .emacs file: + + (if (some conditions are met) (server-start)) + + When this is done, Emacs starts a subprocess running a program called + `server'. `server' creates a Unix domain socket in the user's home + directory named `.emacs_server'. + + To get your news reader, mail reader, etc., to invoke emacsclient, try + setting the environment variable EDITOR (or sometimes VISUAL) to the + value `emacsclient'. You may have to specify the full pathname of the + emacsclient program instead. Examples: + + # csh commands: + setenv EDITOR emacsclient + setenv EDITOR /usr/local/emacs/etc/emacsclient # using full pathname + + # sh command: + EDITOR=emacsclient export EDITOR + + * Normal use + + When emacsclient is run, it connects to the `.emacs_server' socket and + passes its command line options to `server'. When `server' receives + these requests, it sends this information on the the Emacs process, + which at the next opportunity will visit the files specified. (Line + numbers can be specified just like with Emacs.) The user will have to + switch to the Emacs window by hand. When the user is done editing a + file, the user can type "C-x #" to indicate this. This will switch to + another buffer created at the request of emacsclient if there are any. + When "C-x #" has been invoked on all of the files that the emacsclient + requested to be edited, Emacs will send notification of this to `server' + which will pass this on to the emacsclient, which will then exit. + + NOTE: `emacsclient' and `server' must be running on machines which share + the same filesystem for this to work. The pathnames that emacsclient + specifies should be correct for the filesystem that the Emacs process + sees. The Emacs process should not be suspended at the time emacsclient + is invoked. emacsclient should either be invoked from another X window or + from a shell window inside Emacs itself. + + There is an enhanced version of emacsclient/server called `gnuserv' by + Andy Norman <ange@hplb.hpl.hp.com> which is available in the Emacs Lisp + Archive. gnuserv uses Internet domain sockets, so it can work across most + network connections. It also supports the execution of arbitrary Emacs + Lisp forms and also does not require the client program to wait for + completion. It is available via anonymous FTP (Emacs Lisp Archive: + packages/gnuserv.shar). + +42: How do I make Emacs recognize my compiler's funny error messages? + + Write a program which runs the compiler as a child and filters its output, + rearranging as necessary. Install with same name as compiler somewhere in + path. + + Keith Moore <moore@cs.utk.edu> wrote one such for a C compiler under AIX. + Available via FTP: + + /cs.utk.edu:readonly/aixcc.lex + + Jim Frost <jimf@saber.com> wrote another for the IBM xlc compiler on the + RS/6000. (I don't know if these are both for the same compiler.) + Johnathan Vail <vail@tegra.COM> wrote something for a High C compiler + (`hc', which is one of the compilers on the RS/6000, although I think + Johnathan wrote his program for hc on a different computer). + +43: How do I indent switch statements like this? + + Many people want to indent their switch statements like this: + + f() + { + switch(x) { + case A: + x1; + break; + case B: + x2; + break; + default: + x3; + } + } + + I don't believe there is any way to do this exactly without modifying the + Lisp code in c-mode.el. You can set c-indent-level to 4 and + c-label-offset to -2, but this has bad effects elsewhere. {Anyone have a + solution?} + +44: How can I make Emacs automatically scroll horizontally? + + There is no completely correct way of doing this that does not involve + rewriting all commands or writing your own top-level command loop (not a + completely bad idea). Wayne Mesard <wmesard@pescadero.stanford.edu> has + written a particularly advanced kludge called `hscroll.el' that checks + once a second to make sure point is visible. + +45: How do I make Emacs "typeover" or "overwrite" instead of inserting? + + M-x overwrite-mode (a minor mode). + +46: How do I stop Emacs from beeping on a terminal? + + Martin R. Frank <martin@cc.gatech.edu> writes: + + Tell Emacs to use the 'visible bell' instead of the audible bell, and + set the visible bell to nothing. + + Put this in your TERMCAP environment variable: + + ... :vb=: ... + + And evaluate this: + + (setq visible-bell t) + +47: How do I turn down the bell volume in Emacs running under X Windows? + + Under versions of Emacs before 18.58, the bell volume was annoying loud + and difficult to turn off. So upgrading to 18.58 or higher will reduce + + the volume. If you want to turn it off completely, use `xset'. There is + no way to turn the bell off just for Emacs without affecting all other + programs. + + Under Epoch you can do: + + (setq epoch::bell-volume 20) + + Stu Grossman <grossman@sunburn.stanford.edu> wrote a patch that allows the + bell volume to be adjusted from inside Emacs just for Emacs. + +48: How do I tell Emacs to automatically indent a new line to the + indentation of the previous line? + + One solution is Indented Text Mode (M-x indented-text-mode). + + If you have Auto-Fill mode on (a minor mode, see question 32), you can + tell Emacs to prefix every line with a certain character sequence, the + "fill prefix". Type the prefix at the beginning of a line, position point + after it, and then type "C-x ." (set-fill-prefix) to set the fill prefix. + Thereafter, auto-filling will automatically put the fill prefix at the + beginning of new lines, and M-q (fill-paragraph) will maintain any fill + prefix when refilling the paragraph. + + NOTE: If you have paragraphs with different levels of indentation, you + will have to set the fill prefix to the correct value each time you move + to a new paragraph. To avoid this hassle, try one of the many packages + available from the Emacs Lisp Archive. Look up `fill' and `indent' in the + Lisp Code Directory for guidance. + +49: How do I show which parenthesis matches the one I'm looking at? + + If you're looking at a right parenthesis (or brace or bracket) you can + delete it and reinsert it. Emacs will blink the cursor on the matching + parenthesis. + + M-C-f (forward-sexp) and M-C-b (backward-sexp) will skip over balanced + parentheses, so you can see which parentheses match. (You can train it to + skip over balanced brackets and braces at the same time by modifying the + syntax table.) + + Here is some Emacs Lisp that will make the % key show the matching + parenthesis, like in vi. In addition, if the cursor isn't over a + parenthesis, it simply inserts a % like normal. + + ;; By an unknown contributor + + (global-set-key "%" 'match-paren) + + (defun match-paren (arg) + "Go to the matching parenthesis if on parenthesis otherwise insert %." + (interactive "p") + (cond ((looking-at "\\s\(") (forward-list 1) (backward-char 1)) + ((looking-at "\\s\)") (forward-char 1) (backward-list 1)) + (t (self-insert-command (or arg 1))))) + +50: In C mode, can I show just the lines that will be left after #ifdef + commands are handled by the compiler? + + M-x hide-ifdef-mode. (This is a minor mode.) + + You may have to (load "hideif") first. If you want to do this regularly, + put this in your .emacs file: + + (autoload 'hide-ifdef-mode "hideif" nil t) + + {Yes, I know, this should be in lisp/loaddefs.el already.} + +51: Is there an equivalent to the `.' (dot) command of vi? + + (`.' is the redo command in vi. It redoes the last insertion/deletion.) + + No, not really. + + You can type "C-x ESC" (repeat-complex-command) to reinvoke commands that + used the minibuffer to get arguments. In repeat-complex-command you can + type M-p and M-n to scan through all the different complex commands you've + typed. + + To repeat something on each line I recommend using keyboard macros. + +52: What are the valid X resource settings (ie., stuff in .Xdefaults)? + + See the Emacs man page, or the etc/OPTIONS file. Ignore the information + in etc/XDOC which is way out of date. + +53: How do I execute a piece of Emacs Lisp code? + + There are a number of ways to execute (called "evaluate") an Emacs Lisp + "form": + + * If you want it evaluated every time you run Emacs, put it in a file + named `.emacs' in your home directory. + + * You can type the form in the *scratch* buffer, and then type LFD (or + C-j) after it. The result of evaluating the form will be inserted in + the buffer. + + * In Emacs-Lisp mode, typing M-C-x evaluates a top-level form before or + around point. + + * Typing "C-x C-e" in any buffer evaluates the Lisp form immediately + before point and prints its value in the echo area. + + * Typing M-ESC or M-x eval-expression allows you to type a Lisp form in + the minibuffer which will be evaluated. + + * You can use M-x load-file to have Emacs evaluate all the Lisp forms in + a file. (To do this from Lisp use the function `load' instead.) + + These functions are also used for evaluating Lisp forms: + + load-library, eval-region, eval-current-buffer, require, autoload + +54: How do I change Emacs's idea of the tab character's length? + + Example: (setq default-tab-width 10). + +55: How do I insert `>' at the beginning of every line? + + Type "M-x replace-regexp RET ^ RET > RET". + + To do this only in the region, type "C-x n M-x replace-regexp RET ^ RET + > RET C-x w". + + WARNING: The command narrow-to-region (C-x n) is disabled by default + because it can be very confusing (ie., "Oh no! Where did my file go?"). + +56: How do I insert `_^H' before each character in a paragraph to get an + underlined paragraph? + + M-x underline-region. + +57: How do I repeat a command as many times as possible? + + Use "C-x (" and "C-x )" to make a keyboard macro that invokes the command + and then type "M-0 C-x e". + + WARNING: any messages your command prints in the echo area will be + suppressed. + +58: How do I make Emacs behave like this: when I go up or down, the cursor + should stay in the same column even if the line is too short? + + M-x picture-mode. (This is a minor mode, in theory anyway ...) + +59: How do I tell Emacs to iconify itself? + + You need to modify C source and recompile. Either that or get Epoch or + Lucid Emacs instead. Patches have been written by Robert Forsman + <thoth@reef.cis.ufl.edu> and Johan Vromans <jv@mh.nl> to allow Emacs to + iconify itself and by Matt Wette <mwette@mr-ed.jpl.nasa.gov> and + Manavendra K.

(This is actually typical + for regexp syntax.) + +61: How do I perform a replace operation across more than one file? + + The "tags" feature of Emacs includes the command tags-query-replace which + performs a query-replace across all the files mentioned in the TAGS file. + See `Tags:Tags Search' in the online manual. + + In addition, Martin Boyer has written a package named global-replace which + will perform a query-replace across all the files mentioned in the + *compilation* buffer (usually done after a `grep'), which is available via + anonymous FTP: + + /ireq-robot.hydro.qc.ca:pub/emacs/lisp/compile.el.Z + /ireq-robot.hydro.qc.ca:pub/emacs/lisp/global-replace.el.Z + /ireq-robot.hydro.qc.ca:pub/emacs/lisp/query.el.Z + +62: Where is the documentation for `etags'? + + `etags' takes options just like a prior version of ctags, so your ctags + manual (if any) may be useful. {Can someone send me the details on this?} + + + +Bugs/Problems + +63: Does Emacs have problems with files larger than 8 megabytes? + + Most installed versions of GNU Emacs will use 24-bit signed integers (and + 24-bit pointers) internally. This limits the file size that Emacs can + handle to 8,388,607 bytes (2^23 - 1). + + Leonard N. Zubkoff <lnz@lucid.com> suggests putting the following two + lines in src/config.h before compiling Emacs to allow for 26-bit integers + and pointers (and thus filesizes of up to 33,554,431 bytes): + + #define VALBITS 26 + #define GCTYPEBITS 5 + + WARNING: This method may result in `ILLEGAL DATATYPE' and other random + errors on some machines. + + David Gillespie <daveg@csvax.cs.caltech.edu> gives an explanation of why + Emacs uses 24 bit integers and pointers: + + Emacs is largely written in a dialect of Lisp; Lisp is a freely-typed + language in the sense that you can put any value of any type into any + variable, or return it from a function, and so on. So each value must + carry a "tag" along with it identifying what kind of thing it is, eg., + integer, pointer to a list, pointer to an editing buffer, and so on. + Emacs uses standard 32-bit integers for data objects, taking the top 8 + bits for the tag and the bottom 24 bits for the value. So integers (and + pointers) are somewhat restricted compared to true C integers and + pointers. + + Emacs uses 8-bit tags because that's a little faster on byte-oriented + machines, but there are only really enough tags to require 6 bits. + +64: Why can't Emacs find files in current directory on startup? + + The PWD bug has been fixed as of GNU Emacs 18.59. Read on if you are + + running an older version of Emacs. + + + Most likely, you have an environment variable named PWD that is set to a + value other than the name of your current directory. This is most + likely caused by using two different shell programs. `ksh' and (some + versions of) `csh' set and maintain the value of the PWD environment + variable, but `sh' doesn't. If you start sh from ksh, change your + current directory inside sh, and then start Emacs from inside sh, PWD + will have the wrong value but Emacs will use this value. An invalid + + setting for PWD can also be a problem if you use X Windows and csh on an + + RS/6000. See the etc/OPTIONS file for more details. + + + Perhaps an easier solution is not to use two shells. The `chsh' program + can often be used to change one's default login shell. + + You may have PWD set for other reasons. Another possibility is that you + are setting default-directory from your .emacs file. + + Here is a fix by Jim Blandy <jimb@occs.cs.oberlin.edu>: + + >--- emacs/jjj/emacs-18.58/lisp/startup.el Tue Jan 15 23:19:04 1991 + >+++ startup.el Mon Apr 20 00:21:01 1992 + >@@ -81,5 +81,7 @@ + > ;; In presence of symlinks, switch to cleaner form of default directory. + > (if (and (not (eq system-type 'vax-vms)) + >- (getenv "PWD")) + >+ (getenv "PWD") + >+ (equal (nthcdr 10 (file-attributes default-directory)) + >+ (nthcdr 10 (file-attributes (getenv "PWD"))))) + > (setq default-directory (file-name-as-directory (getenv "PWD")))) + > (unwind-protect + +65: How do I get rid of the ^M junk in my Shell buffer? + + For tcsh, put this in your `.cshrc' (or `.tcshrc') file: + + if ($?EMACS) then + if ("$EMACS" == t) then + if ($?tcsh) unset edit + stty nl + endif + endif + + Or put this in your .emacs_tcsh file: + + unset edit + stty nl + + Alternatively, use csh in your Shell buffers instead of tcsh.

This program should be compiled (for the correct + architecture!) and installed with execute permission for everyone in + Emacs's program directory, which is normally /usr/local/emacs/etc. You + can find what this directory is at your site by inspecting the value of + the variable exec-directory by typing "C-h v exec-directory RET". `env' + should also be for the correct architecture (check using `file' command). + + You should also check for other programs named `env' in your path (eg., + SunOS has a program named /usr/bin/env). I don't understand why this can + cause a failure and I don't know a general solution for working around the + problem in this case. + + The `make clean' command will remove `env' and other vital programs, so be + careful when using it. + + It has been reported that this sometimes happened when Emacs was started + as an X client from an xterm window (ie. had a controlling tty) but the + xterm was later terminated. + + See also etc/PROBLEMS for other possible causes of this message. + +67: Why can't I cut from Emacs and paste in other X programs? + + Emacs stores things you "cut" in the X "cut buffers". It also pastes from + the cut buffer `CUT_BUFFER0'. This is obsolete. Most modern X programs + now expect to work with "selections" instead of cut buffers, although some + like `xterm' will try to use the cut buffers if the selection is null. + + Emacs 18.58 contains a "fix" that makes xterm work by default. This + "fix" is that Emacs clears the `PRIMARY' selection when it stores + something in the cut buffer. By making the selection null, xterm will + then fetch from the cut buffer when you try to paste. + + For versions of Emacs prior to 18.58, you can make pasting from Emacs into + xterm work with the following X resources: + + ! Solution by Thomas Narten, should work under X11R3 and later GNU + ! Emacs only copies to CUT_BUFFER0. xterm by default wants to paste + ! from the PRIMARY selection. + XTerm*VT100.Translations: #override \ + ~Meta <Btn2Up>: insert-selection(CUT_BUFFER0,PRIMARY) + + You may have problems copying between Emacs and programs other than xterm + that won't store cut text in the cut buffers or look in the cut buffers + for text to paste (for backwards compatibility with obsolete applications + like Emacs :-). The best workaround is to use the `xcutsel' program as an + intermediary. + + This problem does not exist for Epoch or Lucid Emacs. + +68: Where is the termcap/terminfo entry for terminal type `emacs'? + + The termcap entry for terminal type `emacs' is ordinarily put in the + TERMCAP environment variable of subshells. It may help in certain + situations (eg., using rlogin from shell buffer) to add an entry for + `emacs' to the system-wide termcap file. Here is a correct termcap entry + for `emacs': + + emacs:tc=unknown: + + To make a terminfo entry for `emacs', use `tic' or `captoinfo'. You need + to generate /usr/lib/terminfo/e/emacs. It may work to simply copy + /usr/lib/terminfo/d/dumb to /usr/lib/terminfo/e/emacs. + + Having a termcap/terminfo entry will not enable the use of full screen + programs in shell buffers. Use M-x terminal-emulator for that instead. + + A workaround to the problem of missing termcap/terminfo entries is to + change terminal type `emacs' to type `dumb' or `unknown' in your shell + start up file. `csh' users could put this in their .cshrc files: + + if ("$term" == emacs) set term=dumb + +69: Why does Emacs spontaneously start displaying `I-search:' and beeping? + + Your terminal (or something between your terminal and the computer) is + sending C-s and C-q for flow control, and Emacs is receiving these + characters and interpreting them as commands. (The C-s character normally + invokes the isearch-forward command.) For possible solutions, see + question 131. + +70: Why can't Emacs talk to certain hosts (or certain hostnames)? + + The problem may be that Emacs is linked with a wimpier version of + gethostbyname than the rest of the programs on the machine. This is often + manifested as a message on startup of `X server not responding. Check + your DISPLAY environment variable.' or a message of `Unknown host' from + open-network-stream. + + On a Sun, this may be because Emacs had to be linked with the static C + library. The version of gethostbyname in the static C library may only + look in /etc/hosts and the NIS (YP) maps, while the version in the dynamic + C library may be smart enough to check DNS in addition to or instead of + NIS. On a Motorola Delta running System V R3.6, the version of + gethosbyname in the standard library works, but the one that works with + NIS doesn't (the one you get with -linet). Other operating systems have + similar problems. + + Try these options: + + * Explicitly add the host you want to communicate with to /etc/hosts. + + * Relink Emacs with this line in src/config.h: + + #define LIBS_SYSTEM -lresolv + + * Replace gethostbyname and friends in libc.a with more useful versions + such as the ones in libresolv.a. Then relink Emacs. + + * If you are actually running NIS, make sure that `ypbind' is properly + told to do DNS lookups with the correct command line switch. + + * Use tcp.el and tcp.c from GNUS. This has the additional advantage that + you can use numeric IP addresses instead of names. open-network-stream + currently can't handle numeric addresses. Brian Thomson + <thomson@hub.toronto.edu> has a enhancement to open-network-stream to + allow it to handle numeric addresses. + +71: Why does Emacs say `Error in init file'? + + An error occurred while loading either your .emacs file or the system-wide + lisp/default.el file. For information on how to debug your .emacs file, + see question 29. + + It may be the case that you may need to load some package first, or use a + hook that will be evaluated after the package is loaded. A common case of + this is explained in question 127. + +72: Why does Emacs ignore my X resources (my .Xdefaults file)? + + * Try compiling Emacs with the XBACKWARDS macro defined. There is a bug + in some implementations of XGetDefault, which do not correspond to the + documentation or the header files. + + * Make sure you are either using the class name of `Emacs' (oops, + apparently this is buggy in Emacs 18.58!) or the correct instance name. + The instance name is normally the same as the name of the file Emacs is + in (ie., the last part of argv[0]), but this can be overridden by -rn + command line option or the WM_RES_NAME environment variable. + + WARNING: Reports say using the class name fails in Emacs 18.58. + + WARNING: The advice the man page gives to use `emacs' is often wrong. + + WARNING: Older versions of Emacs got the class name wrong. + + * Emacs currently ignores the -xrm command line argument. + + * Emacs does not yet handle X11R5 screen-specific resources. + + * Emacs has a bug where it ignores color specifications if running on a + 1-bit display (ie. a non-color display). + + * I don't think Emacs will use either of the application-specific resource + files. Thus these environment variables don't affect it: XAPPLRESDIR, + XUSERFILESEARCHPATH, XFILESEARCHPATH. {Correct?} + +73: Why does Emacs take 20 seconds to visit a file? + + The usual cause is that the master lock file, `!!!SuperLock!!!' has been + left in the lock directory somehow. Delete it. + + Mark Meuer <meuer@geom.umn.edu> says that NeXT NFS has a bug where an + exclusive create succeeds but returns an error status. This can cause the + same problem. Since Emacs's file locking doesn't work over NFS anyway, + the best solution is to recompile Emacs with CLASH_DETECTION undefined. + +74: How do I edit a file with a `$' in its name? + + When entering a filename in the minibuffer, Emacs will attempt to expand + a `$' followed by a word as an environment variable. To suppress this + behavior, type "$$" instead. + +75: Why does Shell mode lose track of the shell's current directory? + + Emacs has no way of knowing when the shell actually changes its directory. + This is an intrinsic limitation of Unix. So it tries to guess by + recognizing `cd' commands. If you type `cd' followed by a directory name + with a variable reference (`cd $HOME/bin') or with a shell metacharacter + (`cd ../lib*'), Emacs will fail to correctly guess the shell's new current + directory. A huge variety of fixes and enhancements to Shell mode for + this problem have been written to handle this problem. Check the Lisp + Code Directory (see question 88). + +76: Why doesn't my change to load-path work? + + If you added a directory name containing a tilde (~) to your load-path, + expecting the tilde to be interpreted as your home directory, then you + need to do something like this: + + (setq load-path (mapcar 'expand-file-name load-path)) + +77: Why does the cursor always go to the wrong column when I move up or + down one line? + + You have inadvertently typed "C-x C-n" (set-goal-column) which sets the + "goal column" to the column where the cursor was. To undo this type + "C-u C-x C-n". + + If you make this mistake frequently, you might want to unbind or disable + this command by doing one of these two: + + (define-key ctl-x-map "\C-n" nil) + (put 'set-goal-column 'disabled t) + +78: Why does Emacs hang with message `Unknown XMenu error' with X11R4? + + Many different X errors can produce this message. Here is the solution + to one problem: + + X11 Release 4 (and later, including OpenWindows) enforces some conditions + in the X protocol that were previously allowed to pass unnoticed. You + need to put the X11R4 server into X11R3 bug compatibility mode for Emacs's + Xmenu code to work. You can do this with the command `xset bc'. + +79: Why doesn't display-time show the load average in the mode line + anymore? + + In GNU Emacs 18.56, a change was made in the display-time code. + Formerly, in version 18.55, Emacs used a program named `loadst' to + notify Emacs of the change in time every minute. loadst also sent Emacs + the system load average if it was installed with sufficient privilege to + get that information (or was on a system where no such privilege was + needed). Emacs then displayed this information in the mode line. + + In version 18.56, this code was changed to use a program named `wakeup'. + wakeup doesn't send Emacs any information, it's only purpose is to send + Emacs *something* every minute, thus invoking the filter function in + Emacs once a minute. The filter function in Emacs does all the work of + finding the time, date, and load average. However, getting the load + average requires the privilege to read kernel memory on most systems. + Since giving Emacs this privilege would destroy any security a system + might have, for almost everyone this is not an option. In addition, + Emacs does not have the code built into it to get this information on + the systems which have special system calls for this purpose, even + though loadst had code for this. + + The solution I use is to get the files lisp/display-time.el and + etc/loadst.c from version 18.55 and use those with 18.58. (I have heard + a rumor that loadst disappeared because of the legal action Unipress + threatened against IBM.) + + WARNING: Do not install Emacs setgid kmem unless you wish to destroy + any security your system might have!!!!!!!!!! + + If you are using Emacs 18.55 or earlier, or already using the solution I + describe above, read further: + + The most likely cause of the problem is that `loadst' can't read the + special file /dev/kmem. To properly install loadst, it should be either + setuid to the owner of /dev/kmem, or is should be setgid to the group to + which /dev/kmem belongs. In either case, /dev/kmem should be readable by + its owner or its group, respectively. Assuming the existence of a group + named `kmem', here is an example of how to do this: + + chgrp kmem /dev/kmem + chmod g+r /dev/kmem + chgrp kmem /usr/local/emacs/etc/loadst + chmod g+s /usr/local/emacs/etc/loadst + + Another possibility is that your version of Unix doesn't have the load + average data available in /dev/kmem. Your version of Unix might have a + special system call to retrieve this information (eg., inq_stats under + UMAX), and loadst might not have been enhanced to cope with this. + +80: Why does ispell sometimes ignore the local dictionary? + + You need to update the version of Ispell to 2.0.02. (Or you can switch to + version 3.0 which is still in beta-testing.) A patch is available via + anonymous FTP: + + /archive.cis.ohio-state.edu:pub/gnu/ispell/patch2.Z + + You also need to change a line in ispell.el from: + + (defconst ispell-version "2.0.01") ; Check against output of "ispell -v". + + to: + + (defconst ispell-version "2.0.02") ; Check against output of "ispell -v". + +81: Why does Ispell treat each line as a single word? + + Ispell expects to get its input one word per line. The ispell filter, + which is specified by the variables ispell-filter-hook and + ispell-filter-hook-args, should output at most one word per line. + +82: Are there any security risks in GNU Emacs? + + * the `movemail' incident (No, this is not a risk.) + + Cliff Stoll in his book `The Cuckoo's Egg' describes this in chapter 4. + The site at LBL had installed the `etc/movemail' program setuid root. + Since `movemail' had not been designed for this situation, a security + hole was created and users could get root priveleges. + + `movemail' has since been changed so that even if it is installed setuid + root this security hole will not be a result. + + I have heard unverified reports that the Internet worm took advantage of + this configuration problem. + + * the file-local-variable feature (Yes, a risk, but easy to change.) + + There is an Emacs feature that allows the setting of local values for + variables when editing a file by including specially formatted text near + the end of the file. This feature also includes the ability to have + arbitrary Emacs Lisp code evaluated when the file is visited. + Obviously, there is a potential for Trojan horses to exploit this + feature. + + If you set the variable inhibit-local-variables to a non-nil value, + Emacs will display the special local variable settings of a file that + you visit and ask you if you really want them. This variable is not + mentioned in the manual. - 2. Via anonymous FTP.

However, any new package that + uses find-file or find-file-noselect has to be careful about this. + + For more information, see `File Variables' in the online manual (which, + incidentally, does not describe how to disable the feature). + + There is a new variable in Emacs 18.58 named ignore-local-eval which + turns out to be useless as currently implemented. Ignore it. + + * synthetic X events (Yes, a risk, use MIT-MAGIC-COOKIE-1 or better.) + + Emacs accepts synthetic X events generated by the SendEvent request as + though they were regular events. As a result, if you are using the + trivial host-based authentication, other users who can open X + connections to your X workstatation can make your Emacs process do + anything, including run other processes with your priveleges. + + The only fix for this is to prevent other users from being able to open + X connections. The standard way to prevent this is to use a real + authentication mechanism, such as MIT-MAGIC-COOKIE-1. If using the + `xauth' program has any effect, then you are probably using + MIT-MAGIC-COOKIE-1. Your site may be using a superior authentication + method; ask your system administrator. + + If real authentication is not a possibility, you may be satisfied by + just allowing hosts access for brief intervals while you start your X + programs, then removing the access. This reduces the risk somewhat by + narrowing the time window when hostile users would have access, but DOES + NOT ELIMINATE THE RISK. + + Lucid GNU Emacs does not accept synthetic X events unless you set a + variable. + + * autosave file permissions (Yes, a risk, hard to work around.) + + The file permissions for autosave files are determined solely by the + Emacs process's `umask' value. The permissions of the file being + autosaved are not used. The easiest workaround is to keep sensitive + files in protected directories. Sebastian Kremer has written an + enhanced version of the autosave file name picking code that can avoid + this problem by keeping autosave files in a protected directory. {FTP + information please?} This problem will be fixed in Emacs 19. + + + +Difficulties Building/Installing/Porting Emacs + +83: What should I do if I have trouble building Emacs? + + First look in the file etc/PROBLEMS to see if there is already a solution + for your problem.

Scott Henry <scotth@hoshi.corp.SGi.COM> posted a + patch that fixes the problem for Irix. + +85: Why does linking Emacs with -lX11 fail? + + Emacs needs to be linked with the static version of the X11 library, + libX11.a. This may be missing. + + Under OpenWindows, you may need to use `add_services' to add the + `OpenWindows Programmers' optional software category from the CD-ROM. + + Under HP-UX 8.0, you may need to run `update' again to load the + X11-PRG `fileset'. This may be missing even if you specified `all + filesets' the first time. If libcurses.a is missing, you may need to load + the `Berkeley Development Option' {???}. + + If you are building the MIT X11 sources, you may need to modify your + `site.cf' file to get static versions of the libraries. (Info from David + Zuhn <zoo@cygnus.com>.) + + Other systems may have similar problems. You can always define + CANNOT_DUMP and link with the shared libraries instead. + + To get the Xmenu stuff to work, you need to find a copy of MIT's + liboldX.a. + +86: Why does Emacs 18.55 say `Fatal error (6).Abort' under SunOS 4.1? + + I had hoped this question would go away after Emacs 18.57 was released, + but people continue to compile 18.55. Easiest solution: upgrade. + + This is a result of the SunOS localtime/tzsetwall malloc bug, which was + (finally!) fixed in SunOS 4.1.2. If you actually need the full + explanation, send me e-mail.

Emacs 19 - supports two styles of multiple windows, one with a separate screen for - the minibuffer, and another with a minibuffer attached to each screen. + NOTE: Any files with names ending in `.Z' are compressed, and you should + use `binary' mode in FTP to retrieve them.

Urgent mail may be sent directly to Dave Sill + <de5@ornl.gov> or Dave Brennan <brennan@hal.com> or should contain the + string `urgent' in the subject. The incoming ftp directory is no longer + available at the request of Ohio State. {Is this still true?} - * Incremental syntax analysis for various programming languages (Leif). - * A more sophisticated emacsclient/server model, which would provide - network transparent Emacs widget functionality. + However, if someone has a submission with multiple files (which would be + archived as a tar file) or binary files, then FTP transfer is preferred + and can be arranged via an anonymous FTP site.

So each value must - carry a "tag" along with it identifying what kind of thing it is, e.g., - integer, pointer to a list, pointer to an editing buffer, and so on. - Emacs uses standard 32-bit integers for data objects, taking the top 8 - bits for the tag and the bottom 24 bits for the value. So integers (and - pointers) are somewhat restricted compared to true C integers and - pointers. - - Emacs uses 8-bit tags because that's a little faster on byte-oriented - machines, but there are only really enough tags to require 6 bits. - - -76: Why does Emacs start up using the wrong directory? - - Most likely, you have an environment variable named PWD that is set to a - value other than the name of your current directory. This is most - likely caused by using two different shell programs. "ksh" and (some - versions of) "csh" set and maintain the value of the PWD environment - variable, but "sh" doesn't. If you start sh from ksh, change your - current directory inside sh, and then start Emacs from inside sh, PWD - will have the wrong value but Emacs will use this value. See the - etc/OPTIONS file for more details. - - Perhaps an easier solution is not to use two shells. The "chsh" program - can often be used to change one's default login shell. - -77: How do I edit a file with a "$" in its name? - - When entering a filename in the minibuffer, Emacs will attempt to expand - a "$" followed by a word as an environment variable. To suppress this - behavior, type "$$" instead. - -78: Why does Shell mode lose track of the shell's current directory? - - Emacs has no way of knowing when the shell actually changes its directory. - This is an intrinsic limitation of Unix. So it tries to guess by - recognizing "cd" commands. If you type "cd" followed by a directory name - with a variable reference ("cd $HOME/bin") or with a shell metacharacter - ("cd ../lib*"), Emacs will fail to correctly guess the shell's new current - directory.

(This assumes the value of - search-quote-char is 17 (C-q).) + There are at least three news reading packages that operate inside Emacs. + `rnews' comes with Emacs. GNUS and Gnews come separately. rnews will + be replaced by GNUS in Emacs 19. - Searching for ALL unprintable characters is best done with a "regexp" - search. The easiest regexp to use for the unprintable chars is the - complement of the regexp for the printable chars. + rnews works only with a local news spool directory.

(I have forgotten who originally gave me the idea for this.)) - One solution is the major mode Indented Text Mode (M-x indented-tex-mode). +167: Why is GNUS so slow to start up? - If you have Auto-Fill mode on (a minor mode, see question 93), - you can tell Emacs to prefix every line with a certain character - sequence, the "fill prefix". Type the prefix at the beginning of a - line, position point after it, and then type "C-x ." (set-fill-prefix) - to set the fill prefix. Thereafter, auto-filling will automatically put - the fill prefix at the beginning of new lines, and M-q (fill-paragraph) - will maintain any fill prefix when refilling the paragraph. + GNUS does several things that take quadratic time of the number of + newsgroups that are listed in .newsrc. The quick fix for this is to + remove all the newsgroups in which you have no interest from your .newrc + file by using GNUS's C-k command in the `*Newsgroup*' buffer after + displaying all newsgroups with the L command. If you were to directly + edit your .newsrc to remove the newsgroups, GNUS would add them back. - NOTE: If you have paragraphs with different levels of indentation, you - will have to set the fill prefix to the correct value each time you move - to a new paragraph. To avoid this hassle, try one of the many packages - available from the Emacs Lisp Archive. Look up "fill" and "indent" in the - Lisp Code Directory for guidance. + GNUS uses a quadratic algorithm to check for duplicates when the .newsrc + file is newer than the .newsrc.el file (ie., you edited your .newsrc). + GNUS uses a quadratic algorithm to check for new newsgroups every time it + connects to the news server. {There may be other quadratic algorithms + that I am not aware of.} -112: How do I make Emacs "typeover" or "overwrite" instead of inserting? - + You can speed up GNUS by using the C-k command in the *Newsgroup* buffer + to remove newsgroups from your .newsrc file. - M-x overwrite-mode (a minor mode). + Of course, GNUS will run faster if you make sure it is byte-compiled. -113: How do I show which parenthesis matches the one I'm looking at? + Felix Lee wrote some enhancements called `gnus-speedups.el' that fix some + of the problems.

GNUS supports reading mail stored in MH folders or articles - saved by GNUS. +170: How do I get rid of flashing messages in GNUS for slow connections? - Gnews is styled after `rn' and seems to work like Rmail.

Some people have complained that Gnews is slower than GNUS. + GNUS outputs "NNTP: Reading..." message and then clears them, over and + over.

Wiener <weemba@libra.wistar.upenn.edu>. - The latest version seems to be 2.0, posted October 3, 1988. Matthew - posted some fixes on October 26, 1988. Gnews does not appear to have been - supported after this date. In particular, it has been reported that Gnews - does not work with Emacs 18.57. There is a newsgroup for Gnews called - gnu.emacs.gnews. + Because GNUS is marking crosspostings read. {I think it should do this at + the time the article is read to spread out the load.

(This is a minor mode.) + David Lawrence <tale@uunet.uu.net> explains: - You may have to (load "hideif") first. If you want to do this - regularly, put this in your .emacs file: + The problem is almost always interaction between NNTP and C News. NNTP + POST asks C News's inews to not background itself but rather hang around + and give its exit status so it knows whether the post was successful. + (That wait will on some systems not return the exit status of the + waited for job is a different sort of problem.) It ends up taking a + long time because inews is calling relaynews, which often waits for + another relaynews to free the lock on the news system so it can file the + article. - (autoload 'hide-ifdef-mode "hideif" nil t) + My preferred solution is to change inews to not call relaynews, but + rather use newsspool. This loses some error-catching functionality, but + is for the most part safe as inews will detect a lot of the errors on + its own. The C News folks have sped up inews, too, so speed should look + better to most folks as that update propagates around. - {Yes, I know, this should be in lisp/loaddefs.el already.} +173: Why don't my news postings in GNUS get past the local machine? -117: Is there an equivalent to the "."

In repeat-complex-command - you can type M-p and M-n to scan through all the different complex - commands you've typed. + GNUS generates `Date:' headers without time zones. C-News's `inews' + doesn't replace it with a valid header, but will generate it if not + already there. If it is invalid, the article will not be forwarded + properly.

In that case, it - will only tell you what line of the current "page" you are on. WARNING: - "C-x l" gives the wrong value when point is at the beginning of a line. + GNUS was written for B news, which would generate the `Lines:' header. C + news doesn't. There is a comment in C news's `inews' that you can + uncomment to enable this functionality. Or you can have GNUS generate the + header, for example: - There is no "correct" way to constantly display the current line (or ! - column) number on the mode line in Emacs 18, or to display the line + - numbers next to the lines. Emacs is not a line-oriented editor, and + - really has no idea what "lines" of the buffer are displayed in the window. + - It would require a lot of work at the C code level to make Emacs keep + - track of this.
