Description structural editing of S-expression data
Author Taylor Campbell
Maintainer Taylor Campbell

Paredit is a minor mode for performing structured editing of S-expression data. The typical example of this would be Lisp or Scheme source code.

Paredit helps keep parentheses balanced and adds many keys for moving S-expressions and moving around in S-expressions.

Basic setup

(autoload 'enable-paredit-mode "paredit"
  "Turn on pseudo-structural editing of Lisp code."
(add-hook 'emacs-lisp-mode-hook       'enable-paredit-mode)
(add-hook 'lisp-mode-hook             'enable-paredit-mode)
(add-hook 'lisp-interaction-mode-hook 'enable-paredit-mode)
(add-hook 'scheme-mode-hook           'enable-paredit-mode)

Helpful keybindings

Forward sexp
Backward sexp

Common Customization


(add-hook 'slime-repl-mode-hook 'enable-paredit-mode)

SLIME’s REPL has the very annoying habit of grabbing DEL which interferes with paredit’s normal operation. To alleviate this problem use the following code:

;; Stop SLIME's REPL from grabbing DEL,
;; which is annoying when backspacing over a '('
(defun override-slime-repl-bindings-with-paredit ()
  (define-key slime-repl-mode-map
    (read-kbd-macro paredit-backward-delete-key)
(add-hook 'slime-repl-mode-hook 'override-slime-repl-bindings-with-paredit)
