  • How can I increase Emacs key repeat rate in OS X Mountain Lion

    - by Rob Jones
    Emacs does not seem to respect the OS's key repeat rate. I'm using emacs in the terminal. I've set the repeat rate to as fast as possible by directly editing the settings in the following file (I restarted after making the change): open ~/Library/Preferences/.GlobalPreferences.plist The rest of the system observes the repeat rate. The terminal works as expected, as does vim. But, when I use emacs I still get the annoyingly slow repeat rate.

  • How to refresh tag list in org-mode without closing and reopening emacs

    - by Pete
    In my emacs org-mode org file I have a tag list #+TAGS: OFFICE(o) COMPUTER(c) HOME(h) PROJECT READING(r) PHOTOGRAPHY(p) At some point, I wish to add a new tag to the list, and apply it to an item (using C-c C-c). But the new tag does not show up in the list of selectable tags. In order to fix this, I close and reopen emacs. But I'm sure that isn't necessary, How do I refresh this list without restarting emacs?

  • Reading email from Emacs VM using a secure server (Gmail)

    - by Alan Wehmann
    This is a question (see below) originally entered at https://answers.launchpad.net/vm/+question/108267 and upon the recommendation of Uday Reddy the question and answers are being moved here. The date of the original question was May 4, 2010. One subject of the question is use of the program stunnel with program View Mail (run within Emacs) on a PC running Microsoft Windows, in order to read email from a server that requires use of TSL/SSL (Gmail). See the related question, How to configure Emacs smtp for secure server for using a secure server, for sending email. The programs discussed are Emacs, VM (ViewMail) and stunnel. The platform under discussion is MS Windows. The original question was asked by usr345 on 2010-04-24: I tried to install vm on Windows, but when I tried to get the mail from gmail using ssl, an error emerges, emacs hanges-up. Here is the code from .emacs: (add-to-list 'load-path (expand-file-name "~/vm/lisp")) (add-to-list 'Info-default-directory-list (expand-file-name "~/vm/info")) (require 'vm-autoloads) (setq vm-primary-inbox "~/mail/inbox.mbox") (setq vm-crash-box "~/mail/inbox.crash.mbox") (setq vm-spool-files `((,vm-primary-inbox "pop-ssl:pop.gmail.com:995:pass:usr345:PASSWORD" ,vm-crash-box))) (setq vm-stunnel-program "g:/program files/stunnel/stunnel.exe") So, the question: How to configure pop-ssl on Windows?

  • Permission denied when running emacs from cygwin console

    - by mahesh
    When I run emacs from the cygwin console I get the following error message: bash: /usr/bin/emacs/ :Permission denied I have not changed any settings. I tried to change the autosave settings in the emacs system file but that didn't work so I deleted it and saved the file. It was after that that I started getting this error. Any idea as to why this is?

  • Make emacs aware of files externally moved/renamed on Mac os x

    - by Gyom
    I've been using mac os x for several years, and I realize that I've now gotten used to all applications transparently "following" files as I rename or move them (either via mv on the console or within the Finder's GUI), and emacs is pretty much the only program that does not. This is a shame though, because most of my time in front a screen is actually spent in front of emacs :-) Would anyone have any ideas or pointers about what measures I could take to get that behaviour in emacs ? (yes I know this is "impossible" to acheive in general, but when I just rename a simple file, or move it to a directory nearby, it's a shame I have to close/reopen it for emacs to notice. oh and no, I'm not going to use 'dired' as a file manager :-)

  • Vim equivalent to Emacs C-i?

    - by Culip
    Does Vim have a command equivalent to Emacs' Ctrl-I? Emacs has an extremely useful shortcut "C-I" which fixes indentation of the current line (or selected lines.) For example, suppose you write this tiny code on Emacs: def foo print "boo" end and you are selecting the whole 3 lines. You press "C-I" then the code becomes def foo print "boo" end I can use this in quiet mode i.e. ignoring. Emacs as well. Does anyone know how to do this on Vim?

  • Emacs doesn't use ~/.ssh/config when accessing files on a remote machine

    - by Yotam
    I have a fresh install of arch Linux. I've installed Emacs from the rpos, and my home directory is mounted from a separate partition. I have old settings I've used on my ~/.ssh/config along with authentication keys I've regularly used before. Now, when I try to connect to a remote machine using Emacs, Emacs asks for my password and uses the wrong username. Clearly, Emacs doesn't access my config file. When I try to ssh or scp directly to the machine, things work fine. What do I need to update?

  • Young people using Emacs?

    - by bigmonachus
    I am a college student that has fallen in love with Emacs. I have used IDEs in the past, and although features like Intellisense made the switch to Emacs very hard, I now think that Emacs is much more powerful, and features like Intellisense can be pretty closely matched by various modes depending on language (and I am not referring to M-/). I am happily writing Elisp code for everything that I need that isn't provided by modes or by Emacs itself and I love the way that it adapts and molds to my needs. However, I do think that its main disadvantage is the fact that it has a pretty steep learning curve and that most new programmers will not even begin to learn it out of many common misconceptions. So, I want to know the opinions of young people (or any person who didn't start using Emacs before there were IDEs) that are Emacs users. Just to get some reassurance that Emacs is not dead within our Eclipse-loving generation =). (Opinions of users of any other highly extensible editor like Jedit are also welcome)

  • What is a dotted pair's analogy in other Lisp implementations?

    - by octopusgrabbus
    What is Scheme's dotted pair construct analogous to in other Lisp implementations? I can make a vector or list quite easily, and understand those in Clojure, even though the syntax is a little different, like Clojure's vectors use square brackets []. However, seeing a dotted pair for the first time threw me. It almost looks like it is an implementation of of map. I'm not looking for a discussion, but more for use or the dotted pair equivalent in other Lisp dialects, like Clojure, or even Python. Thanks.

  • Is there a language offering LISP-like macros with a more complex syntax?

    - by blubb
    LISP's macros are extremely powerful constructs, and the inability to introspect and modify the program itself beyond the method signature level has always struck me as a limitation. Yet I favour "complex" syntax because it tends to be closer to natural language. So far I have failed to find a language which combines a powerful macro mechanism such as LISP's with a naturally looking syntax (1). Is anyone aware of such a language? Footnote: I would consider python to have a naturally looking syntax as it allows constructs like this: if 0 < a < 5 and b in list. The avoidance of braces to structure blocks is irrelevant in this case, though.

  • What is the best way to run emacs under Windows?

    - by Zubair
    I tried using the GNU Emacs download, unzipped it and then clicked on emacs.exe, but got some obscure error. Then I tried Cygwin emacs, but when I press ctrl x ctrl c to quit emacs it thinks I pressed ctrl x ctrl "g"!!! I checked all the key mapping and they work otherwise in Emacs. Is there another version of emacs for windows that just works!

  • How do I add color syntax highlighting to GNU emacs?

    - by Alex Reynolds
    I have two versions of emacs available to me on a locked workstation: $ /usr/local/bin/emacs --version GNU Emacs 22.3.1 $ /usr/bin/emacs --version GNU Emacs 21.4.1 In both cases, my terminal type is xterm when I run either version of emacs. When I run the v21 version of emacs, I get syntax coloring for Perl, HTML, and other modes. When I run the v22 version, I do not get syntax coloring. I would like to migrate from the v21 version because the combination of v21 emacs, GNOME Terminal and GNU Screen is eating Ctrl-arrow key chords, which prevents me from moving quickly between words. (OS X Terminal and GNU Screen do not have this issue.) The v22 version allows use of Ctrl-arrow key combinations with GNOME Terminal and GNU Screen. How do I fix the v22 version (or ask my sys admin to fix) so that it once again highlights syntax and allows me to use Ctrl-arrow key combinations?

  • How can you make an emacs macro wait for cscope query results?

    - by Sudhanshu
    I am trying to write a macro which calls cscope-find-functions-calling-this-function on each and every tag in a file displayed in the *Tags List* buffer (created by list-tags command). This should create a buffer which contains list of all functions calling a set of functions defined in a certain file. This is the sequence of keystrokes: 1. <f11> ;; cscope-find-functions-calling-this-function 2. RET ;; newline [shows results of cscope in a split window] 3. C-x C-p ;; mark-page 4. C-x C-x ;; icicle-exchange-point-and-mark 5. <up> ;; previous-line 6. <end> ;; end-of-line [region to copy has been marked] 7. <f7> ;; append-results-to-buffer 8. C-x ESC O ;; [move back to split window on the right] 9. C-x b ;; icicle-buffer [Switch back to *Tags List* buffer] 10. *Tags ;; self-insert-command * 5 11. SPC ;; self-insert-command 12. List* ;; self-insert-command * 5 13. RET ;; newline 14 . <down> ;; next-line [Position point on next tag in the list] Problem: I get no results in the buffer, and I found out that's because Step 3-7 execute even before cscope prints the results of query made on Steps 1-2. I can insert a pause in the macro by using C-x q, but I'd rather like the macro to wait after Step 2, until cscope has returned with the results and only then continue further. I suspect this is not possible through a macro, maybe a LISP function... I'm not a lisp expert myself. Can someone please help? Thanks! Details: I have Icicles installed so by default I get word at point in current buffer as input in minibuffer. F11 is bound to cscope-find-functions-calling-this-function windmove is installed and C-x (C-x ESC o - as shown below) takes you to the right window. F7 is bound to append-results-to-buffer which is defined as: (defun append-results-to-buffer () (interactive) (append-to-buffer (get-buffer-create "c1") (point) (mark))) This function just appends the currently marked region to a buffer named "c1".

  • emacs: how do I use edebug on code that is defined in a macro?

    - by Cheeso
    I don't even know the proper terminology for this lisp syntax, so I don't know if the words I'm using to ask the question, make sense. But the question makes sense, I'm sure. So let me just show you. cc-mode (cc-fonts.el) has things called "matchers" which are bits of code that run to decide how to fontify a region of code. That sounds simple enough, but the matcher code is in a form I don't completely understand, with babckticks and comma-atsign and just comma and so on, and furthermore it is embedded in a c-lang-defcost, which itself is a macro. And I want to run edebug on that code. Look: (c-lang-defconst c-basic-matchers-after "Font lock matchers for various things that should be fontified after generic casts and declarations are fontified. Used on level 2 and higher." t `(;; Fontify the identifiers inside enum lists. (The enum type ;; name is handled by `c-simple-decl-matchers' or ;; `c-complex-decl-matchers' below. ,@(when (c-lang-const c-brace-id-list-kwds) `((,(c-make-font-lock-search-function (concat "\\<\\(" (c-make-keywords-re nil (c-lang-const c-brace-id-list-kwds)) "\\)\\>" ;; Disallow various common punctuation chars that can't come ;; before the '{' of the enum list, to avoid searching too far. "[^\]\[{}();,/#=]*" "{") '((c-font-lock-declarators limit t nil) (save-match-data (goto-char (match-end 0)) (c-put-char-property (1- (point)) 'c-type 'c-decl-id-start) (c-forward-syntactic-ws)) (goto-char (match-end 0))))))) I am reading up on lisp syntax to figure out what those things are and what to call them, but aside from that, how can I run edebug on the code that follows the comment that reads ;; Fontify the identifiers inside enum lists. ? I know how to run edebug on a defun - just invoke edebug-defun within the function's definition, and off I go. Is there a corresponding thing I need to do to edebug the cc-mode matcher code forms?

  • Emacs: Often switching between Emacs and my IDE's editor, how to automatically 'synch' the files?

    - by WizardOfOdds
    I very often need to do some Emacs magic on some files and I need to go back and forth between my IDE (IntelliJ IDEA) and Emacs. When a change is made under Emacs (and after I've saved the file) and I go back to IntelliJ the change appears immediately (if I recall correctly I configured IntelliJ to "always reload file when a modification is detected on disk" or something like that). I don't even need to reload: as soon as IntelliJ IDEA gains focus, it instantly reloads the file (and I hence have immediately access to the modifications I made from Emacs). So far, so very good. However "the other way round", it doesn't work yet. Can I configure Emacs so that everytime a file is changed on disk it reloads it? Or make Emacs, everytime it "gains focus", verify if any file currently opened has been modified on disk? I know I can start modifying the buffer under Emacs and it shall instantly warn that it has been modified, but I'd rather have it do it immediately (for example if I used my IDE to do some big change, when I come back to Emacs what I see may not be at all anymore what the file contains and it's a bit weird).

  • SOLVED: Lisp: macro calling a function works in interpreter, fails in compiler (SBCL + CMUCL)

    - by ttsiodras
    As suggested in a macro-related question I recently posted to SO, I coded a macro called "fast" via a call to a function (here is the standalone code in pastebin): (defun main () (progn (format t "~A~%" (+ 1 2 (* 3 4) (+ 5 (- 8 6)))) (format t "~A~%" (fast (+ 1 2 (* 3 4) (+ 5 (- 8 6))))))) This works in the REPL, under both SBCL and CMUCL: $ sbcl This is SBCL 1.0.52, an implementation of ANSI Common Lisp. ... * (load "bug.cl") 22 22 $ Unfortunately, however, the code no longer compiles: $ sbcl This is SBCL 1.0.52, an implementation of ANSI Common Lisp. ... * (compile-file "bug.cl") ... ; during macroexpansion of (FAST (+ 1 2 ...)). Use *BREAK-ON-SIGNALS* to ; intercept: ; ; The function COMMON-LISP-USER::CLONE is undefined. So it seems that by having my macro "fast" call functions ("clone","operation-p") at compile-time, I trigger issues in Lisp compilers (verified in both CMUCL and SBCL). Any ideas on what I am doing wrong and/or how to fix this?

  • Window decoration of emacs23 window on fluxbox is outside screen

    - by mit
    I am starting emacs remotely over an ssh connection. But on the emacs window I cannot find a way to resize or move it. There is no fluxbox title bar visible, and I guess the title bar is above the visible viewport, because emacs starts vertically with more height than the screen has. The lower border of the emacs window is also below the viewport border, so I cannot resize the window. I am starting emacs like this: emacs23 This is the emacs version: This is GNU Emacs 23.1.1 (x86_64-pc-linux-gnu, GTK+ Version 2.20.0) of 2010-03-29 on yellow, modified by Debian The remote system that runs emacs is 10.04 Lucid Lynx amd64.

  • Programming languages with extensible syntax

    - by Giorgio
    I have only a limited knowledge of Lisp (trying to learn a bit in my free time) but as far as I understand Lisp macros allow to introduce new language constructs and syntax by describing them in Lisp itself. This means that a new construct can be added as a library, without changing the Lisp compiler / interpreter. This approach is very different from that of other programming languages. E.g., if I wanted to extend Pascal with a new kind of loop or some particular idiom I would have to extend the syntax and semantics of the language and then implement that new feature in the compiler. Are there other programming languages outside the Lisp family (i.e. apart from Common Lisp, Scheme, Clojure (?), Racket (?), etc) that offer a similar possibility to extend the language within the language itself?

  • What is a simple way to combine two Emacs major modes, or to change an existing mode?

    - by Winston C. Yang
    In Emacs, I'm working with a file that is a hybrid of two languages. Question 1: Is there a simple way to write a major mode file that combines two major modes? Details: The language is called "brew" (not the "BREW" of "Binary Runtime Environment for Wireless"). brew is made up of the languages R and Latex, whose modes are R-mode and latex-mode. The R code appears between the tags <% and %. Everything else is Latex. How can I write a brew-mode.el file? (Or is one already available?) One idea, which I got from this posting, is to use Latex mode, and treat the code of the form <% ... % as a comment. Question 2: How do you change the .emacs file or the latex.el file to have Latex mode treat code of the form <% ... % as a comment?

  • [emacs] make ibuffer-visit-buffer behave like ido-switch-to-buffer?

    - by Stephen
    Is there a way to make ibuffer-visit-buffer behave like ido-switch-to-buffer (with raise-frame option)? If there is a window/frame containing the buffer I'd like emacs to take me there rather than opening the same buffer in the current window. I guess switch-to-buffer is remapped to ido-switch-to-buffer when ido-mode is turned on, so would doing something like that work in this case (remap ibuffer-visit-buffer to ido-switch-to-buffer)? Thanks

  • Can't open cocoa emacs from terminal using open -a

    - by Shane
    I installed emacs on my MacBook Air running Mac OS X 10.6.5 from this site http://emacsformacosx.com/. I believe this is what used to be called cocoa emacs. I dragged it into my Application folder and it works fine when I run it from there. I want to be able to run it from the Terminal. After some googling, I tried open -a /Application/Emacs.app foo.txt (foo.txt was and existing file). I got two emacs windows - one with welcome screen and one with foo.txt loaded. I tried a few applications in the /Applications directory and they did not seem to behave like this. I had installed it using my own account (an admin account) so after doing ls -l on /Application I noticed that the owner and group were different from the other entries in this folder. I recursively changed the owner and group to root and wheel, like the others, but this did not help. The only thing that looks funny now is that there that ls -l show a @ character which has something to do with extended attributes but I don't know how to check these. Any suggestions on what to check next? Is using the open command the only to run the program? Can I simulate what it does using a shell script?
