I am using emacs 24 on Windows 7 and have installed technomancy's clojure-mode along with paredit 23 beta. I load the source file from my leiningen project and get a repl using clojure-jack-in. The problem is that while paredit is enabled in both Clojure mode and the repl, curly braces are not matched in the repl only in source files.
How can I get it to match braces in the repl as well?
I added the following to my .emacs file, that does the trick for me (I did not invent this myself, it's a snippet I found somewhere online - but I can't remember where):
(defun setup-slime-repl-paredit ()
(define-key slime-repl-mode-map
(kbd "DEL") 'paredit-backward-delete)
(define-key slime-repl-mode-map
(kbd "{") 'paredit-open-curly)
(define-key slime-repl-mode-map
(kbd "}") 'paredit-close-curly)
(modify-syntax-entry ?\{ "(}")
(modify-syntax-entry ?\} "){")
(modify-syntax-entry ?\[ "(]")
(modify-syntax-entry ?\] ")[")
(modify-syntax-entry ?~ "' ")
(modify-syntax-entry ?, " ")
(modify-syntax-entry ?^ "'")
(modify-syntax-entry ?= "'"))
(add-hook 'slime-repl-mode-hook 'setup-slime-repl-paredit)
(add-hook 'slime-repl-mode-hook 'enable-paredit-mode)
Grab Phil Hagelberg's durendal package, which provide some clojure-specific enhancements to slime, then try this snippet:
(require 'durendal)
(durendal-enable t)
(defun slime-clojure-repl-setup ()
(when (string-equal (slime-lisp-implementation-name) "clojure")
(set-syntax-table clojure-mode-syntax-table)
(setq lisp-indent-function 'clojure-indent-function)))
(add-hook 'slime-repl-mode-hook 'slime-clojure-repl-setup)
In future, Phil may include the functionality of durendal in swank-clojure itself as an additional lisp payload, at which point the above would become unnecessary.
