dired: launch program withou stalling emacs

dired: launch program withou stalling emacs

[Alain Muls]

Hi

I am learning to use dired for file operations. I found out how to 
launch a program associated with the extension using eg

(require 'dired-x)
(setq dired-guess-shell-alist-user
       '(("\\.pdf$" "evince")))

The inconvenience of this is that I have to close the program before I 
can resume working in emacs. Is there a possibility to launch the 
pdfviewer evince and be able to work in emacs without closing the pdfviewer?

Tx/Alain

If you are on GNU/Linux you can try `! xdg-open RET'.

Hi Alain,

It should work for _all_ files. What xdg-open does is open the file in
the preferred application as per the settings of the user. If it fails
for you, then your default applications settings is not what it should
be.

I am not sure how to correct this from the command line (you can try
xdg-mime), but from the GUI you can right click a file and set the
defaults by going to the properties menu on almost any modern window
manager.

I believe this is getting off-topic on the emacs list beyond this
point. If your problem persists, try posting on your distro's user
list. Hope this helps.

My problem is not that the OO file does not open, it's that emacs
still remains locked until the file is closed.

Any suggestions on how to invoke xdg-open as a background process?

That should not be the case. Here using xdg-open does not lock up
emacs. I think a previous post in this thread mentioned how to open an
application in the background. You could give that a try.

Run it in the background.

(setq dired-guess-shell-alist-user
        '(("\\.pdf$" "evince * &")))

here is what I use (in my .emacs):

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
(defun dired-do-shell-command-in-background (command)
  "In dired, do shell command in background on the file or directory named on this line."
  (interactive
   (list (dired-read-shell-command (concat "& on " "%s: ") nil (list (dired-get-filename)))))
  (call-process command nil 0 nil (dired-get-filename)))

(add-hook 'dired-load-hook
	  (function (lambda ()
		      (load "dired-x")
		      (define-key dired-mode-map "&" 'dired-do-shell-command-in-background))))

(setq dired-guess-shell-alist-user
      (list (list "\\.wav$" "wavesurfer") (list "\\.au$" "wavesurfer") (list "\\.pdf$" "acroread")
	    (list "\\.doc$" "OOo") (list "\\.xls$" "OOo") (list "\\.tif$" "gqview") 
	    (list "\\.jpg$" "gqview") (list "\\.html$" "firefox") (list "\\.htm$" "firefox")))

H have posted this before, so you could have found it on the web. ;-)
