* Executing External Programs from Emacs

Are there any functions that can launch external programs (not just
command line programs, but also GUI programs) from Emacs? I know that
I can access a shell, and call a program from there, but then emacs is
not operable until I close the program. Prepending the command with
`nohup' is useful, but for some reason it does not work as expected
with all programs, including emacs. I would prefer another way of
doing this - using a specific built-in of emacs lisp if one exists.
Any help would be greatly appreciated. Thanks.

You should read: http://catb.org/esr/writings/taoup/html/
Pay particular attention to the chapter 11.

try using M-x term it does not block your session while running.

if you want to roll your own have a look at start-process function.

This is OS dependent. There are some examples on EmacsWiki for MS Windows.

Tramp does it. Tested with Emacs 23.0.90:

(with-temp-buffer
  (cd "/ssh:remotehost:")
  (add-to-list 'tramp-remote-process-environment
	       (concat "DISPLAY=" (getenv "DISPLAY"))
  (start-file-process "xterm" nil "xterm"))

Best regards, Michael.

if you OS support command line to open the gui app, then you can just
use emacs's shell-command. e.g. in mac os x, to open TextEdit, do

(shell-command "open -a TextEdit")

Q: How to open the current directory in Desktop?

You can define a function and assign it a keyboard shortcut, so that
by pressing a button, emacs will switch you to your operating
systems's file manager (aka Desktop) with the current directory open.

On the Mac OS X, this is done with the “/usr/bin/open” command. So,
press “Alt+! open .” to have Finder open the current directory. You
can define the function this way:

(defun open-with-finder ()
  "Open the current file in Mac's Finder."
  (interactive)
  (shell-command "open ."))

(global-set-key (kbd "<f2>") 'open-with-finder)

For a documentation of OS X's “open” command, see “man open”.

On Microsoft Windows, you can use “explorer.exe” instead of the “open”
command.

From a shell within Emacs, call the command followed by '&'. You can
also do this from with the 'shell-command' function, which is invoked
with M-!. So, to call a pdf viewer, for example, you could do:

M-! xpdf & <return>

Cheers,

Tyler

   Are there any functions that can launch external programs (not just
   command line programs, but also GUI programs) from Emacs?

You could try eev-mode [1].

Hi,

isn't 'call-process' what you are looking for?

Maybe search Google Groups for 'dired-do-shell-command-in-background'.

Greetings

Josef
