search in loaded buffers

search in loaded buffers

[J. David Boyd]

I've scanned the docs, and don't seem to be able to locate what I'm searching
for.

Is there a way in emacs to search (or grep) through all the loaded buffers,
and only the loaded buffers?

Dave,

I have my own home-brewed function for doing that.  Here is what I have 
in my .emacs file.  It is not bullet-proof, but it gets the job done 
(i.e. "No warrantee is expressed or implied ...")  Hope it helps.

(defun search-multiple-buffers (search-string)
   "Search through all currently loaded \"normal\" buffers for the next
occurance of SEARCH-STRING"
   (interactive
    (list (read-string
	  (concat "Search for (" (car search-ring) "): ")
	  nil
	  'search-ring
	  (car search-ring))))

   (unless (interactive-p)
     (push search-string search-ring))

   (let ((start-buffer (current-buffer))
	(buflist (cdr (buffer-list)))
	(save-point (point))
	(start-point (point))
	buffer-type)

     (catch 'buflist
       (while
	  (progn
	    (setq buffer-type
		  (string-to-char (buffer-name (current-buffer))))
	    (if (or (= buffer-type ?*) (= buffer-type ?\ ))
		t
;;	      (not (search-forward search-string nil t))))
	      (not (let ((case-fold-search nil))

Possibly moccur.el will do what you want. At least I hope that's its
name (going by faulty memory). It's in www.emacswiki.org, but I
haven't been able to get it to work for several weeks now. I miss
checking out the new lisp add-ons.

I could be wrong, but it seems to me there's a similar grep package.
