Shutting Down the Emacs Minibus

I have a function that runs programs asynchronously:

(defun app (app-name) (interactive "sRun application: ") (async-shell-command app-name))

And I have a list of all executables from which to choose. I want the app function to work as switch-to-buffer , providing a TAB termination for the user. How to use minibuffer padding in Emacs?

Use the completing-read command. The function will look like

 (defun app () (interactive) (let ((app-name (completing-read "Run application: " program-list))) (async-shell-command app-name)))

It might be more idiomatic to use interactive instead of assigning a variable according to Emacs Lisp Idioms: user input request

 (defun app (app-name) (interactive (list (completing-read "Run application: " app-list))) (async-shell-command app-name))

You can also use (start-process app-name nil app-name) instead of (async-shell-command app-name) if you do not need an output process according to Run the program from Emacs and do not wait for the exit .

See Minibuffer Termination for more ideas on termination in Emacs and Asynchronous Processes for invoking processes from Emacs, as in the GNU manual.

If you want to finish working with possible shell commands without having to maintain a list yourself, and you are using Emacs 23 or later, you can use read-shell-command :

 (defun app (app-name) (interactive (list (read-shell-command "Run application: "))) (async-shell-command app-name))
