Emacs LSL Mode

Since I can't figure out how to attach this or whatever to the page, you'll have to copy-and-paste the text below into a file called "lsl-mode.el" so the autoload in the comments below can work out.
I have modified this slightly to allow for C++ style comments not C comments (// instead of /* */){--RichardR Bleac 08:01, 13 June 2007 (PDT)}

;; ; This software has been given to the PUBLIC DOMAIN. Use it as you see
;; fit. As usual, no warrantees are available, neither expressed nor
;; implied. You use this software at your own risk.
;; To load this into emacs, add the following lines to your .emacs:
;
; (add-to-list 'load-path "/path/to/directory/containing/this/file")
; (autoload 'lsl-mode "lsl-mode" "Load LSL mode." t)
; (add-to-list 'auto-mode-alist '("\\.lsl$" . lsl-mode))
;
;; You should then be able to load up LSL files and get the pretty
;; colors and indentation.
;; This is derived from C-mode, since LSL is so similar. There'll
;; probably be a couple gotchas as a result. I haven't tested this
;; thorougly, but it works well enough for me. If you have any
;; improvements, feel free to contact Brain Curry in game.

Another lsl mode, xlsl-mode by Xah Lee is available at http://xahlee.org/sl/ls-emacs.html
This mode supports syntax coloring, comment/uncomment, reference lookup. It also support syntax checking with lslint and function templates insertion with yasnippet.
==~/.emacs==
First compile the lsl-mode.el:
* M-x byte-compile-file ~/emacs/lsl-mode.el
With the addition to auto-mode-alist, lsl-mode will be enabled automatically when a file named *.lsl is loaded:
<lisp>
;; To use the lsl-mode, add the following to your ~/.emacs file:
;;
(load "~/emacs/lsl-mode.elc")
(setq auto-mode-alist
 (nconc
 '(("\\.lsl$" . lsl-mode))
 auto-mode-alist))
(defun my-reload-lsl ()
 "Reload lsl mode"
 (interactive)
 (unload-feature 'lsl-mode)
 (load "~/emacs/lsl-mode.elc")
)
;;
;; You may want to customize the indentation:
;;
(setq-default c-basic-offset 8
	 tab-width 8
	 indent-tabs-mode t
	 c-default-style "gnu")
;;
;; 'goto-matching-fence' is a very useful function you may want to add
;; to your ~/.emacs (if it doesn´t finally come by default):
;;
(defun goto-matching-fence ()
 (interactive)
 (let (pos dir (mismatch t) (oldpos (point)))
 (cond ((eq (char-syntax (following-char)) ?\))
	 (setq dir -1)
	 (setq oldpos (+ oldpos 1)))
	 ((eq (char-syntax (following-char)) ?\()
	 (setq dir 1)))
 (if dir
	(progn
	 (save-excursion
	 (save-restriction
 ;; Scan across one sexp within that range.
	 (condition-case ()
		 (setq pos (scan-sexps oldpos dir))
		(error nil))
 ;; See if the "matching" paren is the right kind of paren
 ;; to match the one we started at.
	 (if pos
		 (let ((beg (min pos oldpos)) (end (max pos oldpos)))
		 (and (/= (char-syntax (char-after beg)) ?\$)
			 (setq mismatch
			 (not (eq (char-after (1- end))
 ;; This can give nil.
					(matching-paren (char-after beg))))))))
	 )
	 )
	 )
 )
 ;; If they don't properly match, use a different face,
 ;; or print a message.
 (if mismatch
	(message "Paren mismatch")
 (progn (push-mark)
	 (cond ((eq dir 1)
		 (goto-char (- pos 1)))
		 ((eq dir -1)
		 (goto-char pos))))
 )
 )
)
</lisp>
A modified version of lsl-mode.el is available as emacs/lsl-mode.el here.
