This has the same problem as before, it should look something
like this:
;;; -*- lexical-binding: t -*-
;;
;; this file:
;; https://dataswamp.org/~incal/emacs-init/geh.el
(defun search-something (&optional query)
"Search something by using QUERY."
(interactive "sQuery: ")
(unless (and (stringp query)
(not (string= "" query)) )
(setq query "default search") )
(message query) )
;; (search-something "love") ; love
;; (search-something) ; default search
;; M-x search-something RET RET ; default search
;; M-x search-something RET love RET ; love
