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

  - by Shane

  I installed emacs on my macbook air running 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 terminal. After some googling, i tried open -a /Application/Emacs.app foo.txt…

• Telugu (unicode) font rendering in emacs

  - by Prakash K

  [I asked the following question in stackoverflow, and I have been redirected here. I hope I can get some answers here. My question at stackoverflow had two small images showing the example rendering of text. As a new user at superuser, I am not being allowed to include them here, nor I am allowed to post more than one hyperlink. And, I don't…

• emacs - Widget Custom Theme

  - by Abdillah

  I'm starting using emacs. I know that everything of emacs is customizable. But, one thing I can't even found on internet is modifying the default emacs' widget's Look and Feel. Is there some way to custom it's background, shape, etc or just using UTF-8 character (for example checkbox using ? character)? Well, as a new user, I was quite…

• Tmux causes Emacs glitch

  - by killy9999

  Recently I started using Tmux, but I noticed that it causes a strange Emacs glitch. When I open source code for elisp or haskell, the comments aren't highlighted. Only the comment sign is (; in case of elisp, -- in case of haskell). The rest of the commented line is in normal colour. When I run Emacs outside of Tmux everything works as…

• How to scroll the diff buffer easily in Emacs while point is on the minibuffer

  - by RamyenHead

  In Emacs, after a lot of editing, I press C-x s (save-some-buffers), then Emacs asks "Save file ...? (y,n,.... d ...)" for each file, I sometimes answer d (diff) to see the changes, but then it's not easy to scroll the diff buffer because the cursor is on the minibuffer. Scrollbar does not work. C-M-v works, but if I try to back-scroll…

• Running Emacs on Multiple TTYs in screen

  - by Daniel Kessler

  When working with EMACS over SSH, is there any way to spawn a new frame of the same emacs session on a different terminal? In my use case, I have screen running, so I have multiple terminals, and can recover which pseudo terminal they're attached to with pts. Suppose I have two "windows" (in GNU screen parlance). The first one is…

• Home and End keys in Emacs don't work when run from Tmux

  - by Jan Stolarek

  When I run Emacs from Tmux, the Home and End keys do not work (Home key runs the Search command as if C-s was pressed). The problem started when I added this in my ~/.bashrc file: TERM="xterm" export TERM I've read somewhere that TERM variable should not be set manually but this was the only way I was able to solve problems…

• Font size of emacs in ubuntu

  - by Ispinfx

  I use emacs in ubuntu and I use Monaco 10 as its default font. However, the font rendering seems a bit odd compared to my gnome terminal with the same font size: It's a bit smaller and not as clear as that in the terminal. I've tried to avoid simply this with size 11 but it's too large for me. How can I make it the same as…

• Telugu (unicode) font rendering in emacs

  - by Prakash K

  I sometimes edit text in telugu language. However, when I open the file (UTF-8 encoded) in GNU emacs (version 23.1.50.1 on Ubuntu Jaunty) the text rendering is incorrect. The same text file opened in gedit is rendered correctly. Here's a snippet: ????????? ???? ???? ???????? rendred in gedit: And, the emacs rendering of…

• Color highlights have vanished in emacs

  - by Jim Kiley

  I'm using emacs on a remote Linux server that I access via ssh. I'm editing C files that have a non-standard suffix, so I have had to manually enter c-mode with M-x c-mode every time I open one of those files. I found this to be annoying so I started monkeying with my .emacs to make that problem go away. This made all…

• how to get a decent emacs setup on linux

  - by Hersheezy

  I am currently interested in switching from vim to emacs. One of the more compelling reasons for this is the smooth integration with a unix environment. The most experienced emacs users I have seen have a bash prompt at the bottom of their window, with stdout going to a buffer right above it. They then interact with the…

• How do I configure emacs for editing HTML files that contain Javascript?

  - by MakeDummy

  I have started the painful first steps of using emacs to edit an HTML file with both HTML tags and javascript content. I have installed nxhtml and tried using it - i.e set up to use nxhtml-mumamo-mode for .html files. But I am not loving it. When I am editing the Javascript portion of the code the tab indents do not…

• In Emacs, how can I use imenu more sensibly with C#?

  - by Cheeso

  I've used emacs for a long time, but I haven't been keeping up with a bunch of features. One of these is speedbar, which I just briefly investigated now. Another is imenu. Both of these were mentioned in in-emacs-how-can-i-jump-between-functions-in-the-current-file? Using imenu, I can jump to particular methods in…

• emacs lisp mapcar doesn't apply function to all elements?

  - by Stephen

  Hi, I have a function that takes a list and replaces some elements. I have constructed it as a closure so that the free variable cannot be modified outside of the function. (defun transform (elems) (lexical-let ( (elems elems) ) (lambda (seq) (let (e) (while (setq e (car elems)) (setf (nth e…

• Is there any evidence that lisp actually is better than other languages at artificial intelligence?

  - by Joe D

  I asked this question on SO but it was closed fairly promptly (within 3 minutes) because it was too subjective. I then thought to ask it here on Programmers, a site for "subjective questions on software development". Quoting from the original question: There seems to be a long-held belief (mainly by…

• Greenspun's Tenth Rule, does every large project include a Lisp interpreter?

  - by casualcoder

  Greenspun's tenth rule (actually the only rule) states that: Any sufficiently complicated C or Fortran program contains an ad hoc, informally-specified, bug-ridden, slow implementation of half of Common Lisp. My memory is that there are some papers on the topic, perhaps for Borland's Quattro…

• Learning Lisp - Why ?

  - by David

  I really feel that I should learn Lisp and there are plenty of good resources out there to help me do it. I'm not put off by the complicated syntax, but where in "traditional commercial programming" would I find places it would make sense to use it instead of a procedural language. Is there…

• Lisp-style quotation in HTML

  - by InClj

  In Lisp, evaluating '(+ 1 2) produces '(+ 1 2), not 3. It seems that HTML doesn't support Lisp-style quotation so you can't say something like <quote><b>not bold</b</quote in HTML and let it just produce <b>not bold</b instead of not bold. Is there any technical…

• Lisp: Determine if a list contains a predicate

  - by justkt

  As part of a homework assignment in Lisp, I am to use apply or funcall on any predicates I find. My question (uncovered in the coursework) is: how do I know when I've found a predicate in my list of arguments? I've done some basic google searching and come up with nothing so far. We're…

• Why is Lisp used for AI?

  - by Cristián Romo

  I've been learning Lisp to expand my horizons because I have heard that it is used in AI programming. After doing some exploring, I have yet to find AI examples or anything in the language that would make it more inclined towards it. Was Lisp used in the past because it was available, or…

• Emacs recursive project search

  - by hekevintran

  I am switching to Emacs from TextMate. One feature of TextMate that I would really like to have in Emacs is the "Find in Project" search box that uses fuzzy matching. Emacs sort of has this with ido, but ido does not search recursively through child directories. It searches only within…

• Open an Emacs buffer when a command tries to open an editor in shell-mode

  - by Chris Conway

  I like to use Emacs' shell mode, but it has a few deficiencies. One of those is that it's not smart enough to open a new buffer when a shell command tries to invoke an editor. For example with the environment variable VISUAL set to vim I get the following from svn propedit: $ svn…

• Emacs - nxhtml-mode - memory full

  working with nxhtml-mode in emacs, I get problems since a few weeks. While working emacs pauses unexpectingly until showing a message in the mode line "!MEM FULL!"; obviously nxhtml-mode is filling up the memory until emacs stopps to work. I am working with html, php and css files.…

• Gnome terminal eats emacs undo key sequence

  I am running emacs 21 in gnome-terminal with the --nox option. When I press C-_, the font size decreases instead of emacs undoing my previous action. How do I prevent gnome-terminal from eating the input?
