When user completes, user brings to a whole one of candidates, but in
general, does not necessary selects it. Completion of a candidate
preceds selection. Maybe some packages select or may be tuned to
select as soon as candidate is completed, I personally find that
dangerous.

Using external completion like dmenu or rofi, fzf or similar, is
useful when Emacs run on the command line.

(defun dmenu-completing-read (prompt collection)
  ;; &optional predicate require-match initial-input history def inherit-input-method)
  "Uses external `dmenu' command for Emacs completions."
  (let* ((collection (concat (string-join collection "\n") "\n"))
	 (file (string-to-file-force collection "/dev/shm/collection"))
	 (dmenu "dmenu"))
    (with-temp-buffer
      (call-process dmenu file (current-buffer) nil "-fn" "DejaVu:pixelsize=30" "-l" "10" "-i" "-b" "-p" prompt "-nb" "dark goldenrod" "-nb" "black")
      (string-trim (buffer-string)))))

(dmenu-completing-read "Hello: " '("John" "Joe" "Baby"))

In general I would like completion to work on the command line,
without frame, as well.
