;;; durendal.el --- A bucket of tricks for Clojure and Slime.

;; Keywords: lisp clojure slime
;; Created: 2010-08-13
;; Package-Requires: ((clojure-mode "1.7") (slime "20100404") (paredit "22"))
;; This file is not part of GNU Emacs.
;;; Commentary:
;; "Count Roland smites upon the marble stone;
;; I cannot tell you how he hewed it and smote;
;; Yet the blade breaks not nor splinters, though it groans;
;; Upward to heaven it rebounds from the blow."
;; –From The Song of Roland
;; (Translated by Dorothy Sayers, Viking Penguin, NY, NY, 1957)
;; Durendal is a bucket of tricks for Clojure that are too
;; implementation-specific to go in Slime proper but too fancy to go
;; in clojure-mode itself.
;;; Features:
;; * durendal-hide-successful-compile: Hide compilation buffer upon success.
;; * durendal-jack-in: Initiate a lein-swank + slime-connect.
;; * durendal-enable-auto-compile: Compile on save.
;; * durendal-slime-repl-paredit: Turn on paredit in the slime repl.
;; * durendal-enable-slime-repl-font-lock: Use clojure-mode's
;; font-lock settings in SLIME REPL (with tweaks
;; for prompts and printouts); turn off with
;; durendal-disable-slime-repl-font-lock.
;; Call durendal-enable to turn on all Durendal features. To enable
;; features one at a time, simply use the corresponding add-hook call:
;; (add-hook 'clojure-mode-hook 'durendal-enable-auto-compile)
;; (add-hook 'slime-repl-mode-hook 'durendal-slime-repl-paredit)
;; (add-hook 'sldb-mode-hook 'durendal-dim-sldb-font-lock)
;; (add-hook 'slime-compilation-finished-hook 'durendal-hide-successful-compile)
;;; TODO:
;; * ns-unmap binding
;; * bury *SLIME Compilation* buffer on successful compile
;; * package and require paredit 22
