I have a strange interaction with tramp and cygwin-mount (I think: Emacs: Tab completion of file name appends an extra i:\cygwin ). Because of this, I want to disable tramp. I'm unable to find anything in my .emacs which is loading tramp explicitly. I can see "Loading tramp..." when I hit a tab in the find-file minibuffer. I'd like to figure out what package is causing the loading of tramp and disable that. How do I go about doing this? I tried searching for (require 'tramp) but couldn't find anything interesting. The only other option I can think of is to comment out bits of my .emacs one-by

I looked up the dbus package and it seems like all of the functions are built-in to the C source code and there's no documentation for them. How do I use the dbus-call-method function? Google to the rescue... Follow the link for the example, it's not my code so I won't put it here. http://emacs-fu.blogspot.com/2009/01/using-d-bus-example.html I just had the same problem and found the emacs-fu article that comes up when googling a little too basic for my needs. In particular I wanted to export my own elisp methods via dbus, and had problems making sense of the dbus terminology and how it

I'm trying to tweak the dired-find-file function in emacs on Windows XP so that when I open (say) a pdf file from dired it fires up a copy of Acrobat Reader and opens that file with it, instead of opening it within emacs. But I can't work out what variant on shell-command/call-process to use. Here's what I have so far: (defadvice dired-find-file (around dired-find-file-external (filename &optional wildcards)) "Open non-text files with an appropriate external program." (if (string= ".pdf" (substring filename (- (length filename) 4))) ; obviously I'll replace this with something more general

Emacs 24 now has lexically-scoped variables. It also still has dynamically-scoped variables, of course. Now that it has both, I'm quite confused about when a variable will have which kind of scope. There's a lexical-binding variable that controls when lexical binding is enabled, and I think I read something about defvar now declaring a dynamically-scoped variable, but in general I'm pretty lost. Is there a good explanation somewhere of Emacs 24's new scoping rules? Or put another way, when I look at a variable in Emacs Lisp code written for Emacs 24, how do I tell what scope that variable is

Minimal config https://www.refheap.com/18816 Scenario 1. Run 'emacs' from terminal. M-x server-start Run 'emacsclient -c' from terminal. Effect: Theme applied. Scenario 2. Run 'emacs --daemon' from terminal Run 'emacsclient -c' Effect: Theme is not applied. Why is that? .emacs.d/init.d config: (require 'package) (package-initialize) (defun install-pack (p) "A utility function to help in installing emacs package." (unless (package-installed-p p) (package-install p))) (defun install-packs (packs) "A utility function to help in installing emacs packages." (unless package-archive-contents (package

Now this works just fine: (setq al '((a . "1") (b . "2"))) (assq-delete-all 'a al) But I'm using strings as keys in my app: (setq al '(("a" . "foo") ("b" . "bar"))) And this fails to do anything: (assq-delete-all "a" al) I think that's because the string object instance is different (?) So how should I delete an element with a string key from an association list? Or should I give up and use symbols as keys instead, and convert them to strings when needed? If you know there can only be a single matching entry in your list, you can also use the following form: (setq al (delq (assoc <string> al)
