DEL is the same as C-?. This sends - ASCII code 127. +1: What do these mean: C-h, M-C-a, RET, "ESC a", etc.? - ESC means press the "Escape" key. ESC is the same as C-[. This sends - ASCII code 27. + 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. - SPC means press the "Space" key. This send ASCII code 32. + 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. - TAB means press the "Tab" key. TAB is the same as C-i. This send ASCII - code 9. + 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. - 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". + For further information, see `Characters' and `Keys' in the online manual. -2: What do you mean when you write things like this: type "ESC a"? + NOTE: C-? (aka DEL) is ASCII code 127. It is a misnomer to call C-? a + "control" key, since 127 has both bits 5 and 6 turned ON. Also, on very + few keyboards does Control-? generate ASCII code 127. - I will enclose key sequences that are longer than one key inside double - quotes. These notations refer to single keys (some with modifiers): +2: What does "M-x command" mean? - C-x, M-x, M-C-x - RET, LFD, DEL, ESC, SPC, TAB + "M-x command" means type M-x, then type the name of the command, then + type RET. - 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). + 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. -3: What if I don't have a Meta key? + NOTE: Your system administrator may have bound other key sequences to + invoke execute-extended-command. A function key labeled `Do' is a good + candidate for this. - Instead of typing M-a, you can type "ESC a" instead. In fact, Emacs - converts M-a internally into "ESC a" anyway. + To run non-interactive Emacs functions, see question 53. -4: What if I don't have an Escape key? +3: How do I read topic XXX in the on-line manual? - Type C-[ instead. This should send ASCII code 27 just like an Escape - key would. + 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: -5: What does "M-x command" mean? + C-h i m emacs RET m XXX RET - "M-x command" means type M-x, then type the name of the command, then - type RET. + This invokes the Info facility. If you don't already know how to use + Info, type "?" from within Info. - 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. + If I refer you to topic XXX:YYY, you need to type this: - NOTE: Your system administrator may have bound other key sequences to - invoke execute-extended-command. A function key labeled "Do" is a good - candidate for this. + C-h i m emacs RET m XXX RET m YYY RET - To run non-interactive Emacs functions, use M-ESC instead and type a - Lisp form. + WARNING: Your system administrator may not have installed the Info files, + or may have installed them properly. In this case you should complain. -6: What do things like this mean: etc/SERVICE, src/config.h, - lisp/default.el? +4: What do these mean: etc/SERVICE, src/config.h, lisp/default.el? - These are the names of files that are part of the GNU Emacs - distribution. The GNU Emacs distribution is so big that it is divided - into several subdirectories; the important subdirectories are named - "etc", "lisp", and "src". + These are files that come with GNU Emacs. The GNU Emacs distribution is + divided into subdirectories; the important ones are `etc', `lisp', and + `src'. If you use GNU Emacs, but don't know where it is kept on your system, start Emacs, then type "C-h v exec-directory RET".

The variable help-char should hold the value of this character. +8: What are appropriate messages for gnu.emacs.help, gnu.emacs.bug, + comp.emacs, etc.? -9: How do I find out how to do something in GNU Emacs? + The file etc/MAILINGLISTS discusses the purpose of each GNU mailing-list. + (See question 20 on how to get a copy.) For those which are gatewayed + with newsgroups, it lists both the newsgroup name and the mailing list + address. - There are several methods for finding out how to do things in Emacs. + comp.emacs is for discussion of Emacs programs in general. This + includes GNU Emacs along with various other implementations like JOVE, + MicroEmacs, Freemacs, MG, Unipress, CCA, Epsilon, etc. - You should become familiar with the online documentation for Emacs. The - complete text of the Emacs manual is available online in a hypertext - format via the "Info" manual reader. Type "C-h i" to invoke Info. + 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. - You can order a hardcopy of the manual from the FSF. See question 12. + 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 freely modify the + source code and exchange enhancements. Be careful to remove the gnu.* + groups from the `Newsgroups:' line when posting a followup that recommends + such software. - You can list all of the commands whose names contain a certain word - (actually which match a regular expression) using the "command-apropos" - command. Type "C-h a" to invoke this command. + gnu.emacs.bug is a place where bug reports appear, but avoid posting bug + reports to this newsgroup, instead see question 10. - You can list all of the functions and variables whose names contain a - certain word using the "apropos" command. M-x apropos invokes this - command. +9: Where can I get old postings to gnu.emacs.help and other GNU groups? - You may find that command-apropos and apropos are extremely slow on your - system. This will be fixed in Emacs 19. If you can't wait that long, - I can send you the "fast-apropos.el" file that contains the fix. This - file also contains a "super-apropos" command that will list all the - functions and variables whose documentation strings contain a certain - word. + The FSF has maintained archives of all of the GNU mailing lists for many + years, although there may be some unintentional gaps in coverage.

See - question 16 for how to retrieve this file. + 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. -12: How do I get a printed copy of the GNU Emacs manual? + However, RMS says there are circumstances when it is okay to post to + gnu.emacs.help: - You can order a printed copy of the GNU Emacs manual from the FSF for - $15. A set of 6 manuals is $60. + If you have reported a bug and you don't hear about a possible fix, then + after a suitable delay (such as a week) it is okay to post on + gnu.emacs.help asking if anyone can help you. - The full TeX source for the manual also comes with Emacs, if you're - daring enough to try to print out this 300 page manual yourself. (We're - talking about killing an entire tree here. This kind of printer usage - can make you very unpopular. Besides, if you order it from the FSF, the - price may be tax-deductible as a business expense.) + If you are unsure whether you have a bug, RMS describes how to tell: - If you absolutely have to print your own copy, and you don't have TeX, - you can get a PostScript version from: + ... if Emacs crashes, that is a bug. If Emacs gets compilation errors + while building, that is a bug. If Emacs crashes while building, that is + a bug.

(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. -24: Should I send questions directly to people who post a lot on the net, - instead of posting myself? + Here are the Emacs Lisp forms of the above regexps: - I don't know about the others, but please don't send such messages to me - just because you don't want to disturb a lot of people. Send messages - to individuals that concern things that individual has written. + ;; 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 18.58, 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-X11-18.5{5,7} ! + + 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-2.3.tar.Z ! + + 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 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.

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 - EMACS originally was an acronym for Editor MACroS. The first Emacs was - a set of macros written by Richard Stallman for the editor TECO (Tape - Editor and COrrector {Text Editor and COrrector?}) on a PDP-10. - (Amusing fact: many people have told me that TECO code looks a lot like - line noise.) + WARNING: This method may result in `ILLEGAL DATATYPE' and other random + errors on some machines. -26: What is the latest version of GNU Emacs? + David Gillespie <daveg@csvax.cs.caltech.edu> gives an explanation of why + Emacs uses 24 bit integers and pointers: - GNU Emacs 18.55. GNU Emacs 18.56 is coming out with some bug fixes, but - no additional functionality. + 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. -27: When will GNU Emacs 19 be available? + 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. - Good question, I don't know. For that matter, neither do the - developers. It will undoubtedly be available sometime in the 1990s. +64: Why can't Emacs find files in current directory on startup? -28: What will be different about GNU Emacs 19? + 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. - From the latest "GNU's Bulletin": + Perhaps an easier solution is not to use two shells. The `chsh' program + can often be used to change one's default login shell. - Version 19 approaches release with a host of new features: before and - after change hooks; X selection processing (including CLIPBOARD - selections); scrollbars; support for European character sets; floating - point numbers; per-buffer mouse commands; interfacing with the X - resource manager; mouse-tracking; Lisp-level binding of function keys; - and multiple X windows (`screens' to Emacs). + You may have PWD set for other reasons. Another possibility is that you + are setting default-directory from your .emacs file. - Thanks go to Alan Carroll and the people who worked on Epoch for - generating initial feedback to a multi-windowed Emacs. 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. + Here is a fix by Jim Blandy <jimb@occs.cs.oberlin.edu>: - More features of Version 19 are buffer allocation, which uses a new - mechanism capable of returning storage to the system when a buffer is - killed, and a new input system---all input now arrives in the form of - Lisp objects. + >--- 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 - Other features being considered for Version 19 include: +65: How do I get rid of the ^M junk in my Shell buffer? - * Associating property lists with regions of text in a buffer. - * Multiple font, color, and pixmaps defined by those properties. - * Different visibility conditions for the regions, and for the various - windows showing one buffer. - * Incremental syntax analysis for various programming languages. - * Hooks to be run if point or mouse moves outside a certain range. - * Source-level debugging for Emacs Lisp. - * Incrementally saving undo history in a file, so that recover-file also - reinstalls buffer's undo history. - * Static menu bars, and better pop-up menus. - * A more sophisticated emacsclient/server model, which would provide - network transparent Emacs widget functionality. + 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. - Also, Emacs 19 will have a Emacs Lisp source code debugger. + 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. -29: Is there an Emacs that has better mouse and X window support? + 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. + + It is wise to do this in lisp/site-init.el before building Emacs: + + (setq inhibit-local-variables t) + + If Emacs has already been built, the expression can be put in + lisp/default.el instead, or an individual can put it in their own .emacs + file. + + The ability to exploit this feature by sending e-mail to an RMAIL user + was fixed sometime after Emacs 18.52. 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.

Once you have installed lispdir.el and LCD-datafile, then you can + use the "M-x lisp-dir-apropos" command to look things up in the database. + For example, the command "M-x lisp-dir-apropos RET ange-ftp RET" produces + this (outdated) output: + + GNU Emacs Lisp Code Apropos -- "ange-ftp" + + ange-ftp (3.112) 91-08-12 + Andy Norman, <ange@hplb.hpl.hp.com> + archive.cis.ohio-state.edu: + /pub/gnu/emacs/elisp-archive/as-is/ange-ftp.el.Z + transparent FTP Support for GNU Emacs + +89: Where can I get GNU Emacs Lisp packages that don't come with Emacs? + + First, check the Lisp Code Directory to find the name of the package you + are looking for. (See question 88). Then check local archives and + the Emacs Lisp Archive to find a copy of the relevant files. Then, if + you still haven't found it, you can send e-mail to the author asking for + a copy. + + You can access the Emacs Lisp Archive via anonymous FTP: ! + ! + /archive.cis.ohio-state.edu:/pub/gnu/emacs/elisp-archive/ ! + + Fetch the file README first. + + NOTE: The archive maintainers do not have time to answer individual + requests for packages or the list of packages in the archive. If you + cannot use FTP or UUCP to access the archive yourself, try to find a + friend who can, but please don't ask the maintainers. + + NOTE: Any files with names ending in `.Z' are compressed, and you should + use `binary' mode in FTP to retrieve them. You should also use binary + mode whenever you retrieve any files with names ending in `.elc'. + +90: How do I submit code to the Emacs Lisp Archive? + + Submissions should be mailed to elisp-archive@cis.ohio-state.edu. The + lispdir.el package has a function named submit-lcd-entry which will help + you with this. Mail messages (submissions) are automatically saved and + periodically archived. 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?} + + 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. This is faster than + uudecoding, unsharing, etc., and re-packaging files. + + Before submitting anything, please read the file guidelines.Z, which is + available in the archive. Whenever possible, submissions should contain a + complete LCD entry since this helps reduce administrative overhead for the + maintainers. You can include an entry in this format: + + ;; LCD Archive Entry: + ;; package name|author's name|email address + ;; |description + ;; |date|version|archive path + + For example: + + ;; LCD Archive Entry: + ;; tex-complete|Sebastian Kremer|sk@thp.Uni-Koeln.DE + ;; |Minibuffer name completion for editing [La]TeX. + ;; |91-03-26|$Revision: 1.12 $|~/packages/tex-complete.el.Z + + Dave Brennan has software which automatically looks for data in this + format. The format is fairly flexible. The entry ends when a line is + reached with a different prefix or the seventh field terminator is + seen. + + If you are submitting a multi-file submission you should include a file + named "LCD-entry" which contains the archive entry, instead of placing + it in one or more of the individual files. + +91: Where can I get other up-to-date GNU stuff? + + The most up-to-date official GNU stuff is normally kept on prep.ai.mit.edu + and is available for anonymous FTP in the pub/gnu directory. See the + files etc/DISTRIB and etc/FTP for more information. (To get copies of + these files, see question 20.) + + The following sites are all mirror images of the GNU distribution area: + + /prep.ai.mit.edu:pub/gnu/ + + /ftp.uu.net:packages/gnu/ + + /src.doc.ic.ac.uk:gnu/ (available via FTP, NIFTP, FTAM) + + /ftp.win.tue.nl:pub/gnu/ ! + /utsun.s.u-tokyo.ac.jp:ftpsync/prep/ + + /nic.funet.fi:pub/gnu/ + + + The directory at ftp.uu.net is a mirror of prep.ai.mit.edu:pub/gnu, + except that files larger than 1 megabyte {right?} are automatically + split into multiple parts. If you have trouble transferring large + files, you should try here. A file normally named `XXX' is split into + files XXX-split/part[0-9][0-9], and there will be a file named + XXX-split/README which contains the list of parts (especially helpful + when FTP-ing by e-mail), their checksums, and reassembly instructions. + Some of the other mirror sites may have the same property. {Can someone + check this out?

Emacs 18 has some limited X Window System support, but there are problems. Emacs 19 will have amazing mouse and window support. Right - now, there is a modified version of Emacs 18.55 called "Epoch" which has - greatly improved mouse and window support. The latest version of Epoch - is available via: + now, there are Epoch which is derived from GNU Emacs 18.58 and Lucid GNU + Emacs which is derived from an early unreleased version of GNU Emacs 19, + both of which have greatly improved mouse and window support. See + questions 120 and 121. + + The HP unofficial GNU Emacs also has nice mouse support. See question + 95. + + There are numerous Emacs Lisp packages that have been written to extend + Emacs 18's mouse handling capabilities. Some of these packages also have + patches to the C code to provide enhanced capabilities. Look up `mouse' + in the Lisp Code Directory (see question 88). + + There is a package called BAM (Born Again Menus) which provides menus for + + GNU Emacs via an external C program. It does not provide mouse support in + + the Emacs window such as scrollbars, cut-and-paste, etc. + + + NOTE: Epoch only works with the X Window System; it works on ordinary + terminals by invoking regular GNU Emacs. Lucid Emacs does not currently + work on ordinary terminals, although there are plans to fix this. + +93: What is the difference between GNU Emacs and Epoch? + + Marc Andreessen <marca@ncsa.uiuc.edu> writes: + + Epoch is GNU Emacs on steroids: an adaptation of GNU Emacs with lots of + additional support for features made possible by the X11 windowing + system. These features include multiple editing windows, arbitrary + colors and fonts (fixed-width and proportional), selectable zones per + buffer with arbitrary display styles (font, color, underline, stipple, + pixmap), an optional separate minibuffer window, improved keyboard and + mouse handling, full 8-bit character set support, and more. + +94: What is the difference between GNU Emacs and Lucid GNU Emacs? + + This information is condensed from the release notice: + + Lucid GNU Emacs is based on an early version of GNU Emacs version 19 + with many enhancements. It currently requires X Windows to run. For + information on where to get Lucid GNU Emacs see 121. X Windows support + is greatly enhanced over GNU Emacs version 18, including support for + multiple X Windows (a.k.a. screens in Emacs), Zmacs/Lispm style region + highlighting, a customizable, Motif-like menubar, more powerful keymap + support (allowing different actions to be associated with Backspace, + Control-h, etc.), flexible text attribute (e.g. font, color) support on + regional and screen-local basis through X resources and/or lisp, and + support for the X11 selection mechanism. Some other features include + run-time computation of the load-path, support for floating point + numbers, native timer support, and sound file support on Sun + SPARCstations. To build Lucid GNU Emacs, an ANSI C compiler (e.g. gcc) + is required. + +95: Where can I get the "unofficial HP GNU Emacs"? + + The unofficial HP GNU Emacs is available via anonymous FTP: ! + ! + /me10.lbl.gov:pub/interex/HUGE/ ! + /ee.utah.edu:HUGE/ (PLEASE FTP DURING NON-WORK HOURS!!!) ! + + and takes about 35 megabytes of disk space to build. It is useful for + non-HP machines, but some of the added features will only work under + HP-UX. + + You will need to get patches to work with HP-UX 8.0 or on 700 series + machines via e-mail from Darryl Okahata <darrylo@sr.hp.com>. + +96: Where can I get Emacs for my PC running MS-DOS? + + * Demacs + + For 386 or 486 PCs running MS-DOS, there is a version of GNU Emacs + called Demacs. To get Demacs see question 122. + + From the announcement message: + + Demacs is almost a full set of GNU Emacs but does not support some + features: asynchronous process, locking a file, etc. + + Demacs provides following DOS specific features: + + * File type: text or binary file translation. + * "8-bit clean" display mode. + * 8086 software interrupt call by int86 lisp function. + * Machine specific features such as function key support. + * File name completion with drive name. + * Child process (suspend-emacs, call-process). + * Enhanced dired mode which can work without 'ls.exe'. + + To our regret `shell-mode' does not work, but `compile' command works + properly. + + Demacs was developed using an MS-DOS version of gcc called djgpp by + D. J. Delorie <dj@ctron.com> which can compile and run large programs + under MS-DOS, but not under MS Windows. Demacs was derived from Nemacs + rather than straight from GNU Emacs. + + There are a variety of other Emacses for MS-DOS including among them the + following. + + * Freemacs + + Russ Nelson <nelson@sun.soe.clarkson.edu>, the author, describes + Freemacs: + + * Freemacs is free, and it was designed from the start to be + programmable. + * Freemacs is the only IBM-PC editor that tries to be like GNU Emacs. + * Freemacs can only edit files less than 64K in length. + * Freemacs doesn't have undo. + + Carl Witty <cwitty@cs.stanford.edu> reviews Freemacs: + + Better is Freemacs, which follows the tradition of ITS and GNU Emacs + by having an full, turing-complete extension language which is + incompatible with everything else. In fact, it's even closer to ITS + Emacs than GNU Emacs is, because Mint (Freemacs' extension language) + is absolutely illegible without weeks of study, much like TECO. + + To get Freemacs see question 123. + + * MicroEmacs + + MicroEmacs is a descendant of Microemacs {originally by Dave Conroy?}. + It is programmable in a BASIC-like language.

Figure out what the Emacs Lisp syntax is for this character sequence. + Inside an Emacs Lisp string, RET, LFD, DEL, ESC, SPC, and TAB are + specified with `\r', `\n', `\C-?', `\e', ` ', and `\t'.

In this case, for function + keys to be useful, they must generate character sequences that are sent + to the programs running inside the window as input. The `xterm' program + has two different sets of character sequences that it generates when + function keys are pressed, depending on the sunFunctionKeys X resource + and the -sf and +sf command line options. (To find out what these key + sequences are, see question 129.) In addition, with xterm, + you can override what key sequence a specific function key (or any other + key) will generate with the `translations' resource. This, for example: + + XTerm.VT100.Translations: #override \ + <KeyPress>F1: string(0x1b) string("[xyzzy") + + makes the function key F1 generate the character sequence "ESC [xyzzy". + + On the other hand, if Emacs is managing its own X window, the following + description applies. Emacs receives `KeyPress' events from the X server + when a key is pressed while the keyboard focus is in its window. The + KeyPress event contains an X "keysym" code, which is simply an arbitrary + number corresponding to the name of the keysym, and information on which + "modifiers" such as `control' and `shift' are active. For example, the + `Tab' keysym is 0xff09. (Generally, a key on the keyboard will generate a + keysym whose name is the same as the label on the key, ie. the `Tab' key + will normally generate the `Tab' keysym. This can be changed with the + xmodmap program.) Emacs recognizes all the keysyms that correspond to + standard ASCII characters and internally uses the ASCII character instead. + + (WARNING: I am about to describe a gross, disgusting hack to you, have + your barf bag ready.) + + When Emacs receives the X keysym of one of the arrow keys, it behaves + the same as if it had received a letter key with the control modifier + down as follows (this is hard-coded): + + Up becomes C-p + Down becomes C-n + Right becomes C-f + Left becomes C-b + + The way Emacs treats other keysyms depends on what kind of machine it was + compiled on. The type of the display machine is irrelevant! Function + keys are mapped internally to escape sequences, while other keys are + completely ignored. + + 1. If compiled on a Sun, Emacs recognizes these X keysyms that + are normally on a Sun keyboard: + + F1 through F9 + L1 through L10 (same as F11 through F20) + R1 through R15 (same as F21 through F35) + (The keys labelled R8, R10, R12, and R14 usually are mapped to the + X keysyms Up, Left, Right, and Down.) + Break (the `Alternate' key is given this keysym) + + These keys work like Sun function keys. When Emacs recieves the + keysym, it will internally use character sequences that look like "ESC + [ ### z", where ### is replaced by a number. The character sequences + are identical to those generated by Sun's keyboard under SunView. Any + function key not listed above generates "ESC [ - 1 z". + + In order to use these key sequences, they should be bound to commands + using the standard key binding methods, just as if Emacs were running + on a regular terminal. + + WARNING: F11 and L1 are the same keysym in X, as are F12 and L2, etc. + {Yes, this is stupid. Complain to the X consortium.} + + 2. If not compiled on a Sun, the function keys will appear to Emacs in a + way remarkably similar to the keys of a DEC LK201 keyboard (used on + some VT series terminals). These X keysyms will be recognized: + + F1 through F20 + Help (treated same as F15) + Menu (treated same as F16, is the LK201 `Do' key) + Find + Insert (LK201 `Insert Here' key) + Select + Prior (LK201 `Prev Screen' key *** ONLY IN 18.58 AND LATER ***) + Next (LK201 `Next Screen' key *** ONLY IN 18.58 AND LATER ***) + + And finally, the LK201 key labelled `Remove' (or `Delete') is often + mapped to the Delete keysym which generates the DEL character (C-?) + instead of the key sequence given by the LK201 `Remove' key. It may + also be mapped to some other keysym, such as `_Remove', in which case + you can't use it from within Emacs at all. + + Each function key will be internally converted to a character sequence + that looks like "ESC [ ## ~", where ## is replaced by a number. The + character sequences are identical to those generated by a LK201 + keyboard. Any function key not listed above generates "ESC [ - 1 ~". For the complete list of the numbers which are generated by the function - keys, look in the file src/x11term.c. - - However, this may be inadequate for you if you have function keys Emacs - doesn't know about. Johan Vromans <jv@mh.nl> explains: - - There are a number of tricks that can be helpful. The most elegant - solution, however, is to use the function "x-rebind-key". This function - is commented out in the source for good reasons --- it's buggy. - - It is rather easy to replace this function with the function - epoch:rebind-key from the Epoch distribution. - - After implementing this, all keyboard keys can be configured to send - user definable sequences, e.g. + keys, look in the file src/x11term.c at the definitions of the function + stringFuncVal. + + If you are running Emacs on a Sun machine, even if your X display is + running on a non-Sun machine (eg., an X terminal), you get the setup + described above for Suns. The determining factor is what type of + machine Emacs is running (was compiled) on, not what type of machine + your X display is on. + + If you have function keys not listed above on your keyboard, you can use + `xmodmap' to change their keysym assignments to get keys that Emacs will + recognize, but that may screw up other programs. + + X resources are not used by Emacs to affect the key sequences generated. + In particular, there are no X key "translations" for Emacs. + + If you have function keys not listed above and you don't want to use + xmodmap to change their names, you might want to make a modification to + your Emacs. Johan Vromans <jv@mh.nl> has made available a patch for Emacs + that adds the x-rebind-key function of Epoch to Emacs 18.58. This allows + another layer of key rebinding before Emacs even sees the keys, and in + this layer you can rebind all of the keys and modifier combinations as + well. - (x-rebind-key "KP_F1" 0 "\033OP") - - This will have the keypad key PF1 send the sequence \eOP, just like an - ordinary VTxxx terminal. + Anonymous FTP: + /ftp.eu.net:gnu/emacs/FP-Xfun.Z + + /ftp.urc.tue.nl:pub/tex/emacs/FP-Xfun + - Another method is to handle the keys in the C source.

This is also a good - method. The advantage of sending the plain escape sequences is that you - require only one setup for Emacs running under X and on normal - terminals, e.g. + After implementing this, all keyboard keys can be configured to send + user definable sequences, eg., (x-rebind-key "KP_F1" 0 "\033OP") - will have key PF1 send \eOP, and, probably in another setup file: + This will have the keypad key PF1 send the sequence "ESC O P", just like + an ordinary VT series terminal. - (global-set-key "\eOP" 'specific-function) - - to bind PF1 to a function.

Test whether there is data in stdin's stdio buffer before calling - "select" using something like "((fileptr)->_cnt > 0)". Best choice. - 2. Remove call to select by not defining "TIMEOUT" in "common/conf.h". - 3. Put "setbuf (stdin, NULL)" in the NNTP server in the right spot. - This would be very inefficient. - 4. Rewrite the server to use an alarm instead of "select". + NOTE: Your arrow keys may send sequences beginning with "ESC O" when + Emacs is running, even if they send sequences beginning with "ESC [" at + all other times. This is because Emacs uses any command there may be + in your terminal's termcap entry for putting the terminal into + "Application Keypad Mode". Just map these sequences the same way as + above. -67: Why can't I paste a selection I made in Emacs into my xterm window? + The next two cases are problems even if there is a initialization file for + your terminal type. + + 2. The initialization file for your terminal doesn't bind arrow keys. + + If your terminal type is `xterm', you will have to bind the arrow keys + as in part 1 above, since the xterm.el file doesn't do anything useful. + There may be other terminal types with the same problem. - A person whose name I lost writes: + 3. Your terminal's arrow keys send individual control characters. + + For example, the arrow keys on an ADM-3 send C-h, C-j, C-k, and C-l. + + There is not much Emacs can do in this situation, since all the control + characters except for C-^ and C-\ are already used as Emacs commands. + It may be possible to convince the terminal to send something else when + you press the arrow keys; it is worth investigating. + + You have to make the hard choices of how to rebind keys to commands to + make things work the way you want. Another alternative is to start + learning the standard Emacs keybindings for moving point around: C-b, + C-f, C-p, and C-n. Personally, I no longer use the arrow keys when + editing because I have switched keyboards so many times. + + 4. Your terminal's arrow keys send sequences beginning with "ESC [". + + Due to an extremely poor design decision (ie., these sequences are ANSI + standard), none of the the terminal-specific initialization files that + are distributed with Emacs will bind these character sequences to the + appropriate commands by default. (This also applies to any other + function keys which generate character sequences starting with "ESC + [".) This is because it was deemed far more important to preserve the + binding of M-[ to the backward-paragraph command. It appears that this + will change in Emacs 19. + + Some of the terminal-specific initialization files that come with Emacs + provide a command enable-arrow-keys that will fix this problem. To get + this automatically invoked, put this in your .emacs: + + (setq term-setup-hook + (function + (lambda () + (if (fboundp 'enable-arrow-keys) (enable-arrow-keys))))) + + We put this in our lisp/default.el file, so users don't have to worry + about it: + + ;; don't override a user's term-setup-hook + (or term-setup-hook + (setq term-setup-hook + (function + (lambda () + (and (fboundp 'enable-arrow-keys) + ;; don't override a user key mapping + (eq 'backward-paragraph (lookup-key esc-map "[")) + (enable-arrow-keys)))))) + + If your terminal type is `sun', you should put this in your .emacs + instead (or in addition to the above): + + (setq sun-esc-bracket t) + + It is possible that the terminal-specific initialization file for your + terminal type was written locally and does not follow the rule + mentioned above. In this case you may need to inspect it to find out + how to enable the arrow keys. (Actually, if it was written locally, it + probably enables the arrow keys by default.) + +136: How do I "swap" two keys? - The strange interaction between Emacs, xterm, and the cut buffers is - because most xterm clients use selections instead of (well, superceding) - cut buffers. If there is a selection around, xterms will use that - instead of the cut buffer.

RMAIL + provides no obvious way to reverse this transformation. Kyle Jones has + + aptly named this "the great Emacs Mail Eating Monster". To convert a mail + + file back to standard Unix format, there are several methods: - - -Emacs Lisp programming: - -76: What dialect of Lisp is Emacs Lisp? + * Use the rmail-output ("C-o") command within RMAIL on each message in the + file. First use M-x rmail or M-x rmail-input to visit the RMAIL file in + Rmail mode. Type "1 j" to go to the first message. Use the C-o command + to output the message to a Unix format file. Type "n" to go to the next + message. Repeat. - It's the dialect of Lisp called Emacs Lisp. (No joke!) People also - call it elisp or e-lisp. (NOTE: The term "Elisp" is trademarked by - someone else.) + * If the file contains hundreds of messages, you may not want to repeat + this for all of them. Instead of the above, after getting to the first + message type this (where "mbox" is the file you want to put the messages + in): -77: How close is Emacs Lisp to Common Lisp? + C-x ( C-o mbox RET M-s ^From: RET M-0 C-x ) - Pretty far. GNU Emacs Lisp is case-sensitive, uses dynamic scoping, - doesn't have packages, doesn't have multiple return values, doesn't have - reader macros, etc. For people used to Common Lisp, some of the - functions in Common Lisp that are not in Emacs Lisp by default are - provided in the file lisp/cl.el. There is a Texinfo manual describing - these functions in man/cl.texinfo. + (The rmail-search command ("M-s") is used instead of just "n" because it + is the only command which will cause an error when it reaches the last + message in the file, which is necessary to terminate the keyboard macro. + This will fail if there are messages in the file that don't have a + `From:' header. This assumes rmail-delete-after-output is nil.) -78: How do I execute a piece of Emacs Lisp code? + It is wise to save a copy of the RMAIL file first, in case you make a + mistake. - There are a number of ways to execute (called "evaluate") an Emacs Lisp - "form": + * There are software packages available for converting files or even + entire directories of BABYL files to standard Unix format. These are + helpful in this situation, but are intended mainly for people who have + used RMAIL for a long time and are converting to some other mail reader. + Lookup `rmail', `vm', and `babyl' in the Emacs Lisp Archive (see + question 89). - * If you want it evaluated every time you run Emacs, put it in a file - named ".emacs" in your home directory. + You may wish to disable RMAIL to avoid accidentally destroying your mbox + file (I have this in my .emacs): - * You can type the form in the "*scratch*" buffer, and then type C-j - after it. The result of evaluating the form will be inserted in the - buffer. + (put 'rmail 'disabled t) ; avoid mbox destruction - * In in Emacs-Lisp mode, typing M-C-x evaluates a top-level form before - or around point. +159: How do I make Emacs automatically start my mail/news reader? - * Typing "C-x C-e" in any buffer evaluates the Lisp form immediately - before point and prints its value in the echo area. + Example: - * Typing M-ESC or M-x eval-expression allows you to type a Lisp form in - the minibuffer which will be evaluated. + emacs -f gnus - * 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.) + Also: -79: How do I make a set of operations fully local to a region? + alias gnus 'emacs -f gnus' - Use narrow-to-region inside of save-restriction. + It is probably unwise to automatically start your mail or news reader from + your .emacs file. This would cause problems if you needed to run two + copies of Emacs at one time. Also, this would make it difficult for you + to start Emacs quickly when you needed to. -80: How can I highlight a region? +160: How do I read news under Emacs? - There are ways to get highlighting in GNU Emacs 18.55, but they all - require patching the C code of Emacs and rebuilding. They are also slow - and the highlighting disappears if you scroll or redraw the screen. One - patch is by Kenichi Handa <handa@etl.go.jp>. + 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. - You can hightlight regions in a variety of ways in Epoch. GNU Emacs 19 - will have everything you need, but won't be out soon. + rnews works only with a local news spool directory.

If you set gnus-thread-hide-subject to non-nil, GNUS + will only display the subject of the first posting in a thread, even if + some of the replies use different subjects. It hides the subjects by + putting them past the edge of the window and setting truncate lines to t. - If you're looking at a right parenthesis (or brace or bracket) you can - delete it and reinsert it. + If your screen looks messed up, then for some reason truncate-lines in + your `*Subject*' buffer has been set to nil. It should be set to t. - M-C-f (forward-sexp) and M-C-b (backward-sexp) will skip over balanced - parentheses, so you can see which parentheses match.

In addition, if the cursor isn't over a - parenthese, it simply inserts a % like normal. +167: Why is GNUS so slow to start up? - (By an unknown contributor.) + 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. - (global-set-key "%" 'match-paren) + 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.} - (defun match-paren (arg) - "Go to the matching parenthesis if on parenthesis otherwise insert %." - (interactive "p") - (cond ((looking-at "[([{]") (forward-sexp 1) (backward-char)) - ((looking-at "[])}]") (forward-char) (backward-sexp 1)) - (t (self-insert-command (or arg 1))))) + You can speed up GNUS by using the C-k command in the *Newsgroup* buffer + to remove newsgroups from your .newsrc file. -90: 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? + Of course, GNUS will run faster if you make sure it is byte-compiled. - M-x picture-mode. (This is a minor mode, in theory anyway ...) + Felix Lee wrote some enhancements called `gnus-speedups.el' that fix some + + of the problems. See the Emacs Lisp Archive. + -91: How do I read news under Emacs? +168: How do I catch up all newsgroups in GNUS? - There are at least three news reading packages that operate inside - Emacs. "rnews" comes with Emacs. "GNUS" and "Gnews" come separately. + In the `*Newsgroup*' buffer, type the following magical incantation: - {I've never used rnews; could someone write a description? BTW, rnews - will be replaced with GNUS in Emacs 19.} + M-< C-x ( C-@ c y C-u C-@ C-e C-f C-f M-0 C-x ) - Both GNUS and Gnews handle reading news over NNTP. I think both can - also read from a local news spool. GNUS also supports reading mail - stored in MH folders or articles saved by GNUS. + Leave off the "M-<" if you only want to catch up from point to the end of + the `*Newsgroup' buffer. - GNUS is written (mostly) by Masanobu Umeda. His (?) latest e-mail - address was umerin@tc.nagasaki.go.jp, but I don't think he has an e-mail - address right now. The latest version is GNUS 3.13.

(This is a minor mode.) + If you really want to kill on one of these headers, you can do it like + this: - You may have to (load "hideif") first.

Johan Vromans <jv@mh.nl> wrote a fix. Others have also written + fixes. - No, not really. +171: Why is catch up slow in Gnews/GNUS? - 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. + Because GNUS is marking crosspostings read. {I think it should do this at + the time the article is read to spread out the load.

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. ! + ! + 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. ! - The file etc/SUN-SUPPORT includes the document "Using Emacstool with GNU - Emacs". Also read the man page for emacstool (etc/emacstool.1). +173: Why don't my news postings in GNUS get past the local machine? -95: How do I get Emacs to display the current line number on the mode line? + Three possible reasons: local distribution, C News date problem (see + question 174, and the path problem. This piece of code may fix the path ! + problem for you: ! + ! + (setq gnus-use-generic-path t) ! - There is no "correct" way to constantly display the current line number - on the mode line in Emacs 18. 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. +174: Why is the GNUS-generated `Date:' header invalid? - Emacs 19 will probably be able to do this, but probably not with great - efficiency. + 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. Quick fix: - To find out what line of the buffer you are on right now, do "M-x - what-line". Typing "C-x l" will also tell you what line you are on, - provided the buffer isn't separated into "pages" with C-l characters. - 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. + (defun gnus-inews-date () nil) - People have written various kludges to display the current line number - on the mode line.
