GooAndEmacs

To load the goo mode with font-lock support, you probably want to add the following to your .emacs:

(load "/path_to_goo/emacs/goo")
(setq auto-mode-alist (cons `("\\.goo\\'" . goo-mode) auto-mode-alist))

To run goo from within emacs, allowing you to use C-c C-e to execute the last expression and other such fun, you probably want to add the following to your .emacs:

(autoload 'run-goo "/path_to_goo/emacs/goo-shell" "Run a goo shell." t)
(setq auto-mode-alist
     (cons '("\\.goo\\'" . goo-mode) auto-mode-alist))
(setq goo-program-name "/path_to_goo/bin/g2c")

Where path_to_goo will most likely be the same thing you set GOO_ROOT to if you were a responsible individual. 'Make sure that your emacs session is exposed to environment settings for both GOO_ROOT and GOO_BUILD_ROOT!'

To start a goo session, remember to hit M-x run-goo.

Also included in the emacs diretory is James' fancy font-lock mode with nested shading. I don't think the current version of our wiki will let us embed images though, so you'll have to imagine what fun it may bring.
