Could someone please give me hand with a function that detects whether a frame named "xyz" exists, and if so, then switch to that frame. I'm using frame-cmds to give each frame a user-defined name: http://www.emacswiki.org/emacs/frame-cmds.el I would imagine it is similar to a buffer, but I'm not finding anything on Google. Here is the buffer function: (defun buffer-exists (bufname) (not (eq nil (get-buffer bufname)))) (defun lawlist-switch-to-buffer-xyz () (interactive) (if (buffer-exists "xyz") (switch-to-buffer "xyz") )) Here is a semi-related post: https://superuser.com/questions/358037

I want to set the indentation mode to tabs only, with a 4 character width for any mode. This seems like a trivial thing, but I have not had success. Every mode seems to have its own variables and options. I've tried doing this for Perl and R without success. Things that have not worked: (setq-default tab-width 4) (setq standard-indent 4) (setq-default r-indent-level 4) (setq perl-indent-level 4) (setq c-basic-offset 4) works for c-mode but nothing else. Am I forgetting something? Did I set the wrong variables? Is there no such option? I work with a variety of languages (R, Perl, sh, C/C++ etc.

I'm just starting to learn emacs (woohoo!) and I've been mucking around in my .emacs quite happily. Unfortunately, I don't know Lisp yet, so I'm having issues with the basics. I've already remapped a few keys until I fix my muscle memory: (global-set-key (kbd "<f9>") 'recompile) That's fine. But how can I tell a key to 'simulate pressing several keys'? For instance, I don't know, make <f1> do the same as C-u 2 C-x } (widen buffer by two chars). One way is to look up that C-x } calls shrink-window-horizontally , and do some sort of lambda thing. This is of course the neat and elegant way (how

I use the function TeX-parse-error defined by Ivan Andrus at the bottom of Emacs latexmk function throws me into an empty buffer in order to automatically open the *TeX Help* buffer when there was an error during the compilation ( C-c C-c ). After correcting an error and compiling again, the *TeX Help* buffer remains open (although the error has been corrected). Is there any way to adjust the function (unfortunately, I'm not experienced in elisp programming) so that the *TeX Help* buffer is closed if the error was resolved and updated (and still open) if the error wasn't resolved? That would

I want to allow the user to choose their own command in the "customize" emacs backend (and generally be able to store an executable form name in a variable) but this does not work : (defun dumb-f () (message "I'm a function")) (defvar my-function "dumb-f") (my-function) ==> Debugger entered--Lisp error: (invalid-function "dumb-f") (setq my-function 'dumb-f) (my-function) ==> Debugger entered--Lisp error: (invalid-function "dumb-f") I tried various forms, but still no luck, and I'm having a hard time searching for it, I get kilopages of results about functions and variables, but none about how

I'm making some tedious calls to a bunch of functions, but the parameters will be determined at runtime. I wrote a simple function to keep my code DRY but giving it a name is unnecessary. I don't use this function anywhere else. I'm trying to do it the way I would in Scheme, but I get a void-function error: (let ((do-work (lambda (x y z) (do-x x) (do-y y) ;; etc ))) (cond (test-1 (do-work 'a 'b 'c)) (test-2 (do-work 'i 'j 'k)))) I could stick it all into an apply (e.g., (apply (lambda ...) (cond ...)) ) but that isn't very readable. Is there a better way? Like other lisps (but not Scheme),
