I have a keybinding I just made that essentially will go to the end of a line, insert a semicolon, return, and auto-indent. I'd like to only add the semicolon if it doesn't already exist. In other words, go to the end of the line, if a semicolon is there, return. If a semicolon is not there, add one, then return. I'm brand spanking new to emacs, and I'm sure this is a task that others have resolved, but I'm having trouble googling for a solution. Thanks, Steve
(defun hello-there () (interactive) (move-end-of-line) (unless (looking-back ";") (insert ";")) (newline-and-indent))Then you would want to bind this to only some modes, and not globally. E.g., this way:
(add-hook 'prog-mode-hook (lambda () (local-set-key (kbd "C-c ;") 'hello-there))) This binds "C-c ;" to that command. Hope that helps, Deniz
