;;; clojure-mode.el --- Major mode for Clojure code
;; Copyright (C) 2007, 2008, 2009 Jeffrey Chu and Lennart Staflin
;;
;; Authors: Jeffrey Chu <jochu0@gmail.com>
;; Lennart Staflin <lenst@lysator.liu.se>
;; Phil Hagelberg <technomancy@gmail.com>
;; URL: http://www.emacswiki.org/cgi-bin/wiki/ClojureMode
;; Version: 1.1
;; Keywords: languages, lisp
;; This file is not part of GNU Emacs.
;;; Commentary:
;; Provides font-lock, indentation, and functions for communication
;; with subprocesses for the Clojure language. (http://clojure.org)
;;; Installation:
;; If you use ELPA, you can install via the M-x package-list-packages
;; interface. This is preferrable as you will have access to updates
;; automatically.
;; If you need to install by hand for some reason:
;; (0) Add this file to your load-path, usually the ~/.emacs.d directory.
;; (1) Either:
;; Add these lines to your .emacs:
;; (autoload 'clojure-mode "clojure-mode" "A major mode for Clojure" t)
;; (add-to-list 'auto-mode-alist '("\\.clj$" . clojure-mode))
;; Or generate autoloads with the `update-directory-autoloads' function.
;; Paredit users:
;; Download paredit v21 or greater
;; http://mumble.net/~campbell/emacs/paredit.el
;; Use paredit as you normally would with any other mode; for instance:
;;
;; ;; require or autoload paredit-mode
;; (defun lisp-enable-paredit-hook () (paredit-mode 1))
;; (add-hook 'clojure-mode-hook 'lisp-enable-paredit-hook)
;; The clojure-install function can check out and configure all the
;; dependencies get going with Clojure, including SLIME integration.
;; To use this function, you may have to manually load clojure-mode.el
;; using M-x load-file or M-x eval-buffer.
;;; Todo:
;; * installer doesn't work when git port is blocked
;; * hashbang is also a valid comment character
;; * do the inferior-lisp functions work without SLIME? needs documentation
