  • dates and times in emacs lisp

    - by Stephen
    Hi, I understand emacs lisp is great for handling dates and times, but does it have a function to convert strings to internal representation of integers using formats like %Y, %m, %d, %H, %M, %S, and so on? And also, in the emacs reference manual, it says that times are lists of two or three integers, but is there a more formal specification or description? ~ Thanks ~

  • Emacs keybindings for texboxes in firefox?

    - by Seamus
    I'm so used to emacs that sometimes, when I'm typing something in a textbox in firefox, I sometimes try and do C-p to move up a line. It is seriously annoying to have to cancel a print dialog box every time I try and move about my text. If it's not horrendously complicated, I'd like to have keybindings that emulate emacs inside textboxes in firefox... Obviously, I wouldn't need all the keybindings, but movement, marking, killing and yanking would be useful. Is this an insane request?

  • Emacs color-theme suitable for maximum readability when projected [closed]

    - by Julien Chastang
    I will be giving a lisp talk in a few days at a meetup I regularly attend. Attendees have complained in the past about my emacs color theme not being readable when projected. What is a emacs color-theme suitable for maximum readability when projected? Post "Q & A" update I did some experimentation and found these color themes to be acceptable for projection Blue Mood blackOnGray Dark Blue 2

  • How can I export emacs documents in 13.04?

    - by Whippy
    When I try to export a document from org-mode in emacs, c-X, c-E now results in 'Can't find library org' whereas in 10.04 it opened the export dialog allowing me to produce html, pdf etc. from the source org file. Searching with Google, I found this bug for redhat which looks closely related. The trouble is I don't know how to get hold of the emacs-el package it talks about in ubuntu in order to try its workaround so I'm currently stuck.

  • What is the difference between the Client and GTK versions of emacs?

    - by David
    My Ubuntu 10.04 desktop has three versions of emacs: emacs-snapshot (client) emacs-snapshot (GTK) GNU Emacs 23 I mostly use emacs-snapshot, but I also use regular emacs in terminal mode emacs -nw. However, it is not clear to me what the difference is between the client and GTK versions of emacs-snapshot is, which one is launched by emacs-snapshot at the terminal, and if I should uninstall one or just ignore it.

  • Emacs stops taking input when a file has changed on disk [migrated]

    - by recf
    I'm using Emacs v24.3.1 on Windows 8. I had a file change on disk while I had an Emacs buffer open with that file. As soon as I attempt to make a change to the buffer, a message appears in the minibuffer. Fileblah.txt changed on disk; really edit the buffer? (y, n, r or C-h) I would expect to be able to hit r to have it reload the disk version of the file, but nothing happens. Emacs completely stops responding to input. None of the listed keys work, nor do any other keys as far as I can tell. I can't C-g out of the minibuffer. Alt-F4 doesn't work, not does Close window from the task bar. I have to kill the process from task manager. Anyone have any idea what I'm doing wrong here? In cases it's various modes not playing nice with each other, for reference, my init.el is here. Nothing complex. Here's the breakdown: better-defaults (ido-mode, remove menu-bar, uniquify buffer `forward, saveplace) recentf-mode custom frame title visual-line-mode require final newline and delete trailing whitespace on save Markdown mode with auto-mode-alist Flyspell with Aspell backend Powershell mode with auto-mode-alist Ruby auto-mode-alist Puppet mode with auto-mode-alist Feature (Gherkin) mode with auto-mode-alist The specific file was a markdown file with Github-flavored Markdown mode and Flyspell mode enabled.

  • emacs: force ido-mode to forget history...

    - by Stephen
    Hi, I wonder if I can keep ido from not remembering my history and only show completions for files that are in the current directory when I am searching for a file. I understand that this history feature is useful at times, but I often end up editing the incorrect file because I think I am editing file called 'abc.txt' in the current directory but in fact I am editing the file by the same name in another one that I previously visited (often happens when there is not an 'abc.txt' in the current directory, as I mistakenly assume). From reading the ido.el file I thought to set in my .emacs file (also evaluated these expressions in running emacs instance): (custom-set-variables '(ido-enable-last-directory-history nil) '(ido-record-commands nil) ) and deleted a file called .ido.last in ~/, but still it remembers some previous files I've visited before making these changes. How can I purge my previous history, and I am not entirely sure what the difference between the two variables above are but seems to have done the trick to keep ido from remembering files I visit in the future? Thanks for your help!

  • where to download emacs manuals as offline html files

    - by Jisang Yoo
    When you press C-h i in Emacs, it shows what's called the top of the INFO tree, and it links to all kinds of manuals: AUCTeX, Org Mode, Emacs, Emacs FAQ, Emacs Lisp Intro, Elisp, ... . Is there a place where I can download all of them at once as html files? GNU Home page has links to some of them in html format: http://www.gnu.org/software/emacs/manual/elisp.html_node.tar.gz http://www.gnu.org/software/emacs/manual/emacs.html_node.tar.gz But I cannot find a link to a single tar.gz file packing all of them.

  • emacs starting maximised

    - by Seamus
    I want a keyboard shortcut to open emacs in a maximised window. I tried emacs --fullscreen, but that is full screen rather than maximised window... That is, the emacs window covers ubuntu menu bars. emacs -fw gets a full width window and emacs -fh gets a full height window, but if you put both options, it only reads the second one. At the moment, I just have another keyboard shortcut for maximising a window. Is there a way to get emacs to start maximised? Ubuntu 9.10, emacs 22, if that makes a difference.

  • Fixing fill-paragraph with comments in Emacs 23.2.1

    - by Silfheed
    I just upgraded to emacs 23.2.1 when I finally upgraded to ubuntu 10.10, but the first thing I noticed is that fill-paragraph (M-q) doesnt work nicely with comments anymore or at least do not work the way they did in emacs 23.1.? that I had before the upgrade. The main issue is that if I have a commented line such as //This is a long comment to illustrate an issue I have with emacs lorem ipsum and then do fill-paragraph (M-q) afterwards, I get //This is a long comment to illustrate an issue I have with emacs lorem ipsum whereas I should get //This is a long comment to illustrate an issue I have with //emacs lorem ipsum I've killed my .emacs file to try and narrow down where the issue is popping up, but this still pops up even in vanilla emacs.

  • Problem with the keyboard layout in Emacs (ubuntu 12.04)

    - by user61648
    I've got some problems with the keyboard layout. I have a french AZERTY keyboard. When I switch to another layout (I tested both programmer DVORAK and Greek) everything seems fine. However, in emacs, I have a more unexpected (at least for me) behavior. For example, in DVORAK, I thought to obtain: On my french Keyboard - DVORAK X - Q Alt-X - Alt-Q But I have: X - Q Alt-X - Alt-X When I press the Alt key, the layout change seems to be inactivated. I precise I didn't activated any shortcut containing the Alt key for the layout switching. Moreover, I'm not sure this behavior is restricted to Emacs, but I don't use shortcuts like Alt-... in another application. Is a such behavior normal ? And in this case, how can I use a shortcut like Alt-Q when I switch to DVORAK ?

  • make emacs in a terminal use dark colors and not light font-lock colors

    - by vy32
    I am using emacs on MacOS 10.6 with Terminal. I have a white background. It's very hard to read quoted C++ strings. They are coming up in pale green. Keywords are in turquoise. After searching through the source I cam across cpp.el and have determined that I am using the cpp-face-light-name-list instead of cpp-face-dark-name-list. Apparently this function is supposed to chose the correct list based on the background color: (defcustom cpp-face-default-list nil "Alist of faces you can choose from for cpp conditionals. Each element has the form (STRING . FACE), where STRING serves as a name (for `cpp-highlight-buffer' only) and FACE is either a face (a symbol) or a cons cell (background-color . COLOR)." :type '(repeat (cons string (choice face (cons (const background-color) string)))) :group 'cpp) But it doesn't seem to be working. What should I put in my .emacs file so that I get the cpp-face-dark-list instead of cpp-face-light-list? Thanks!

  • configuring slime in emacs

    - by CodeKingPlusPlus
    I am in the process of configuring slime for emacs. So far I have read about basic functionality for common lisp such as C-c C-q which invokes the command slime-close-parens-at-point which places the proper number of parens where your mouse is. Another command that seemed cool was invoked by C-c C-c and it would pass the code you are editing in a buffer to the REPL, and "compile" it. Why won't these commands work for me? Anyway, I have downloaded slime via M-x list-packages and do not seem to have this functionality (C-h w and then any of these commands tells me that these commands do note exist). So, I saw a bunch of other slime extensions such as slime-repl', 'slime-fuzzy' and 'hippie-expand-slime'. So I again usedM-x list-packages` and downloaded them. Still I did not have these commands. Here is the content of my emacs file relevant to slime: ;;;Common Lisp and Slime (add-to-list 'load-path "/home/s2s2/.emacs.d/elpa/slime-20130626.1151") (add-to-list 'load-path "/home/s2s2/.emacs.d/elpa/slime-repl-201000404") (add-to-list 'load-path "/home/s2s2/.emacs.d/elpa/hippie-expand-slime-20130226.1656") (add-to-list 'load-path "/home/s2s2/.emacs.d/elpa/slime-fuzzy-20100404") (require 'slime) (setq slime-lisp-implementations `((sbcl ("/usr/bin/sbcl")) (ecl ("/usr/bin/ecl")) (clisp ("/usr/bin/clisp" "-q -I")))) (require 'slime-repl) (require 'slime-fuzzy) (require 'hippie-expand-slime) When I execute M-x slime I get the following message in the inferior-lisp buffer where I can execute common lisp code (however, shouldn't this be the slime-repl since I required it?): STYLE-WARNING: redefining EMACS-INSPECT (#<BUILT-IN-CLASS T>) in DEFMETHOD STYLE-WARNING: Implicitly creating new generic function STREAM-READ-CHAR-WILL-HANG-P. WARNING: These Swank interfaces are unimplemented: (DISASSEMBLE-FRAME SLDB-BREAK-AT-START SLDB-BREAK-ON-RETURN) ;; Swank started at port: 46533. Then a slime-error buffer is created with the contents: Invalid protocol message: Symbol "CREATE-REPL" not found in the SWANK package. Line: 1, Column: 28, File-Position: 28 Stream: #<SB-IMPL::STRING-INPUT-STREAM {10056B9C33}> (:emacs-rex (swank:create-repl nil) "COMMON-LISP-USER" t 5) How should I modify my emacs file to give me the functionality of those commands? In my emacs file am I not loading the necessary files? Do I need to install an additional package? If you need more information let me know! All help is much appreciated!

  • Application specific environment variable settings

    - by SuperElectric
    I'm trying to work around a known bug in Ubuntu 9.10, where using the scrollbar in emacs causes text to be highlighted, and the cursor to move. This page here shows that you can fix this by setting an environment variable before launching emacs: $ GDK_NATIVE_WINDOWS=1 emacs So a lazy fix would be to alias "emacs" in my .bashrc: alias emacs="GDK_NATIVE_WINDOWS=1 emacs" This, however, has the drawback of setting this environment variable for all subsequent commands run from that shell. Is there any way to set GDK_NATIVE_WINDOWS=1 for just emacs, whenever I run emacs?

  • Emacs: methods for debugging python

    - by Tom Willis
    I use emacs for all my code edit needs. Typically, I will use M-x compile to run my test runner which I would say gets me about 70% of what I need to do to keep the code on track however lately I've been wondering how it might be possible to use M-x pdb on occasions where it would be nice to hit a breakpoint and inspect things. In my googling I've found some things that suggest that this is useful/possible. However I have not managed to get it working in a way that I fully understand. I don't know if it's the combination of buildout + appengine that might be making it more difficult but when I try to do something like M-x pdb Run pdb (like this): /Users/twillis/projects/hydrant/bin/python /Users/twillis/bin/pdb /Users/twillis/projects/hydrant/bin/devappserver /Users/twillis/projects/hydrant/parts/hydrant-app/ Where .../bin/python is the interpreter buildout makes with the path set for all the eggs. ~/bin/pdb is a simple script to call into pdb.main using the current python interpreter HellooKitty:hydrant twillis$ cat ~/bin/pdb #! /usr/bin/env python if __name__ == "__main__": import sys sys.version_info import pdb pdb.main() HellooKitty:hydrant twillis$ .../bin/devappserver is the dev_appserver script that the buildout recipe makes for gae project and .../parts/hydrant-app is the path to the app.yaml I am first presented with a prompt Current directory is /Users/twillis/bin/ C-c C-f Nothing happens but HellooKitty:hydrant twillis$ ps aux | grep pdb twillis 469 100.0 1.6 168488 67188 s002 Rs+ 1:03PM 0:52.19 /usr/local/bin/python2.5 /Users/twillis/projects/hydrant/bin/python /Users/twillis/bin/pdb /Users/twillis/projects/hydrant/bin/devappserver /Users/twillis/projects/hydrant/parts/hydrant-app/ twillis 477 0.0 0.0 2435120 420 s000 R+ 1:05PM 0:00.00 grep pdb HellooKitty:hydrant twillis$ something is happening C-x [space] will report that a breakpoint has been set. But I can't manage to get get things going. It feels like I am missing something obvious here. Am I? So, is interactive debugging in emacs worthwhile? is interactive debugging a google appengine app possible? Any suggestions on how I might get this working?

  • Code folding for LaTeX in Emacs

    - by ShreevatsaR
    Is there an Emacs minor-mode (or piece of elisp code) that lets you selectively hide/show environments while in LaTeX mode? For instance, I would like to move to the beginning of a long \begin{figure} block, hit a keystroke, and have the contents of that figure environment hidden from view. Similarly with \begin{proof} and so on, and ideally even with \subsections. Is this possible? I just tried hs-minor-mode, allout-mode, and outline-minor-mode, but most of them don't recognize LaTeX's environments, e.g. hs-minor-mode fails with "scan error: unbalanced parentheses". I would prefer not to have to enter explicit folding marks like {{{ as in folding-mode. [Ideally it would be great if the folding were persistent, but I see that that question doesn't have an accepted answer yet.]

  • Overriding a function in Emacs Lisp

    - by scrapdog
    I would like to temporarily override the kill-new function. I have a way I want to reimplement kill-new that works in only in certain contexts, but I don't want to reimplement a special version of kill-region on top of that. (kill-new is called from kill-region) Since Emacs Lisp uses dynamic scoping, this should be possible, right? (On the other hand, it seems that this would be an unsafe thing to support, and it might make me a bit nervous knowing that it is possible...) I have experimented with using let and fset, but so far have found no way to get it to work as expected. So, hopefully someone can fill in the blank in the following pseudocode: (defun my-kill-new (string &optional replace yank-handler) (message "in my-kill-new!")) (defun foo () (some-form-that-binds-a-function (kill-new my-kill-new) (kill-region (point) (mark)))) What should some-form-that-binds-a-function be? Or am I barking up the wrong tree?

  • idomatic batch processing of text in emacs?

    - by Stephen
    In python, you might do something like fout = open('out','w') fin = open('in') for line in fin: fout.write(process(line)+"\n") fin.close() fout.close() (I think it would be similar in many other languages as well). In emacs lisp, would you do something like (find-file 'out') (setq fout (current-buffer) (find-file 'in') (setq fin (current-buffer) (while moreLines (setq begin (point)) (move-end-of-line 1) (setq line (buffer-substring-no-properties begin (point)) ;; maybe (print (process line) fout) ;; or (save-excursion (set-buffer fout) (insert (process line))) (setq moreLines (= 0 (forward-line 1)))) (kill-buffer fin) (kill-buffer fout) which I got inspiration (and code) from here. Or should I try something entirely different? And how to remove the "" from the print statement? Thanks!

  • emacs list-buffers behavior

    - by Stephen
    In GNU emacs, every time I hit Ctrl-x Ctrl-b to see all of my buffers, the window is split to show the buffer list, or if I have my window already split in 2 (for instance, I will have a shell running in the lower window), the buffer list appears in the other window. My desired behavior is for the buffer list to appear in my active window so that I can select the buffer I want and continue to working in the same window, rather than having to Ctrl-x Ctrl-o to the other buffer, selecting the buffer (with enter) and editing that buffer in the other window... I've googled for it but it doesn't seem to be a common desire? I wonder if anyone has an elispy (or other) solution?

  • Emacs and Long Shell Commands

    - by darrint
    Is there a way to run a shell command, have the output show up in a new buffer and have that output show up incrementally? Eshell and other emacs terminal emulators do a find job of this but I see no way to script them. What I'd like to do is write little elisp functions to do stuff like run unit tests, etc. and watch the output trickle into a buffer. The elisp function shell-command is close to what I want but it shows all the output at once when the process finishes.

  • Emacs auto-minor-mode based on extension

    - by vermiculus
    I found this question somewhat on the topic, but is there a way [in emacs] to set a minor mode (or a list thereof) based on extension? For example, it's pretty easy to find out that major modes can be manipulated like so (setq auto-mode-alist (cons '("\\.notes$" . text-mode) auto-mode-alist)) and what I'd ideally like to be able to do is (setq auto-minor-mode-alist (cons '("\\.notes$" . auto-fill-mode) auto-minor-mode-alist)) The accept answer of the linked question mentions hooks, specifically temp-buffer-setup-hook. To use this, you have to add a function to the hook like so (add-hook 'temp-buffer-setup-hook 'my-func-to-set-minor-mode) My question is two-fold: Is there an easier way to do this, similar to major modes? If not, how would one write the function for the hook? It needs to check the file path against a regular expression. If it matches, activate the desired mode (e.g. auto-fill-mode).

  • Use XQuery to Access XML in Emacs

    - by Gregory Burd
    There you are working on a multi-MB/GB/TB XML document or set of documents, you want to be able to quickly query the content but you don't want to load the XML into a full-blown XML database, the time spent setting things up is simply too expensive. Why not combine a great open source editor, Emacs, and a great XML XQuery engine, Berkeley DB XML? That is exactly what Donnie Cameron did. Give it a try.
