emacs waiting for external program to exit

emacs waiting for external program to exit

[Leo]

Hi there,

If I open a .pdf file in dired with evince, Emacs is frozen until that
program exits.

Is there anyway I can't avoid that i.e. I'd like to be able to continue
using the same Emacs session?

Thanks,

Can't you put evince into the background? Either use a shell script  
as go-between or use a function for dired-x that was sent to the list  
recently, could be in May or June ... It was about launching an  
external programme in the background.

I know this kind of solutions. It is ugly and not general.

For one thing, I don't want to write a wrapper for all external
programs.

Just redefining `dired-run-shell-command' by replacing shell-command
works for me.

,----
| (require 'dired-aux)
| 
| (defun xwl-shell-command-asynchronously (cmd)
|   (start-process-shell-command cmd nil cmd))
| 
| ;; Run shell command at background
| (defun dired-run-shell-command (command)
|   (let ((handler
| 	 (find-file-name-handler
| 	  (directory-file-name default-directory)
| 	  'shell-command)))
|     (if handler
| 	(apply handler 'shell-command (list command))
|       ;; (shell-command command)))
|       (xwl-shell-command-asynchronously command))) ; xwl
|   ;; Return nil for sake of nconc in dired-bunch-files.
|   nil)
