Emacs Tip #1: Paranthesis matching

December 18, 2007

Emacs has so many ways to match the paranthesis in your code. There is the paren-mode and there are many other hacks. They are all fine, I like the way how vi does it. In vi, you place your cursor on a paranthesis and press % key and it will jump to the matching paranthesis.

To enable this feature, put the following code in your ~/.emacs file and restart.

(global-set-key "%" 'match-paren)
(defun match-paren (arg)
"Go to the matching parenthesis if on parenthesis otherwise insert %."
(interactive "p")
(cond ((looking-at "\\s\(") (forward-list 1) (backward-char 1))
((looking-at "\\s\)") (forward-char 1) (backward-list 1))
(t (self-insert-command (or arg 1)))))
