Going through a list using the minibuffer

[arvid-harnack]

Hi Yuri,



Using the command you described, how can I get tho selection into a variable

named "sel" ?



(completing-read "Choose a Greek letter: " '("alpha" "beta" "gamma") nil t)



Is like this good?



  (let* ( (gkser '("alpha" "beta" "gamma"))
     (gksel (completing-read
         "Choose a Greek letter: " gkser nil t)))
    (message "gksel %s" gksel))



Regards

You basically want ‘(completing-read "Choose a Greek letter: "
'("alpha" "beta" "gamma") nil t)’, except that it will give you the
selected option value rather than its index.
