Hi Phil,
Just installed the emacs-starter-kit and clojure-mode, and i can't delete
curly braces when in clojure-mode. Is there a logical explanation for that?
Phil – 2009-06-12T09:37:15Z
Hingebjerg: That's a feature of paredit-mode; it enforces that you can't
delete parens (or other matched chars) unless they're empty so you
don't end up with invalid structure in your code. It's unbelievably handy/
addictive once you get used to it, but if you're not sure what's going on it
can be pretty annoying.

14. you’re using the emacs starter kit
or, you’re already familiar setting the modes up
you’ve got paredit and show-parens modes
M-x paredit-mode
M-x show-paren-mode

15. install?
;;; Install paredit by placing `paredit.el' in `/path/to/elisp', a
;;; directory of your choice, and adding to your .emacs file:
;;;
;;; (add-to-list 'load-path "/path/to/elisp")
;;; (autoload 'paredit-mode "paredit"
;;; "Minor mode for pseudo-structurally editing Lisp code."
;;; t)
;;;
;;; Toggle Paredit Mode with `M-x paredit-mode RET', or enable it
;;; always in a major mode `M' (e.g., `lisp' or `scheme') with:
;;;
;;; (add-hook M-mode-hook (lambda () (paredit-mode +1)))

75. add paredit to the SLIME REPL

76. customize
;;; Customize paredit using `eval-after-load':
;;;
;;; (eval-after-load 'paredit
;;; '(progn ...redefine keys, &c....))
;;;
;;; ... Now `)' is bound to a
;;; command that does not insert a newline, and `M-)' is bound to the
;;; command that inserts a newline. To revert to the former behaviour,
;;; add the following forms to an `eval-after-load' form for paredit.el
;;; in your .emacs file:
;;;
;;; (define-key paredit-mode-map (kbd ")")
;;; 'paredit-close-round-and-newline)
;;; (define-key paredit-mode-map (kbd "M-)")
;;; 'paredit-close-round)
