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 'paredit-mode "paredit"
"Minor mode for pseudo-structurally editing Lisp code." t)
(add-hook 'emacs-lisp-mode-hook (lambda () (paredit-mode +1)))
(add-hook 'lisp-mode-hook (lambda () (paredit-mode +1)))
(add-hook 'lisp-interaction-mode-hook (lambda () (paredit-mode +1)))
(add-hook 'scheme-mode-hook (lambda () (paredit-mode +1)))
Helpful keybindings
- [C-M-f]
- Forward sexp
- [C-M-b]
- Backward sexp
Common Customization
SLIME REPL
(add-hook 'slime-repl-mode-hook (lambda () (paredit-mode +1)))
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) nil))
(add-hook 'slime-repl-mode-hook 'override-slime-repl-bindings-with-paredit)
