But, if you still want to learn how to use a function both interactively and in elisp code, you should read the Elisp documentation about 'interactive'. It explains how to write functions that you can use as commands. (info "(elisp)Using Interactive") =20=20=20 In your case, here is a possible solution: #+begin_src elisp (defun view-parens (style) "Visualise parentheses and expressions using STYLE. STYLE must be a symbol." (interactive (list=20 (intern (completing-read "Visualise: " '("bracemk" "ex= pression" "mixed") nil t "mixed")))) (setq show-paren-style style) ) #+end_src =20=20=20=20 Note 1: The function 'intern' transforms a string into a symbol; you then d= on't need a 'pcase' anymore. Note 2: Your line: (setq 'show-paren-style 'parenthesis) =20=20=20=20=20=20=20=20=20 should have been: =20=20=20=20=20=20=20=20 (setq show-paren-style 'parenthesis) =20=20=20=20=20=20=20=20=20 as 'setq' expects a non-quoted symbol.
