"GNU Emacs is an operating system, lacking only a decent text editor."
Major Mode[edit | edit source]
The package below is a simple mode for Emacs syntax highlighting, indentation and flymake support. Emacs version 24.x.x is required (beta as of Feb. 28 2012) for it to work. Visit http://www.gnu.org/software/emacs/ and scroll down to Obtaning/Downloading GNU Emacs.
It must be placed in one of your Emacs load paths (~/emacs-24.x.x/lisp/prog-modes/papyrus-mode.el) before the changes to .emacs and thus this package will work.

To open the Emacs config file, hit C-x C-f (Emacs jargon, hit ctrl+x then ctrl+f). Windows will give focus to the small command line interface at the bottom of the Emacs program. Enter in '~/' and press RET (Emas jargon for enter / return). You should see a list of files and directories, click .emacs. Open .emacs and add the following Lisp statement to the end. This will tell Emacs to load the papyrus-mode.el package you saved in ~/emacs-24.x.x/lisp/prog-modes as papyrus-mode.el earlier.
(require 'papyrus-mode)
Remember, Emacs is much more than a simple text editor. While it may be frustrating to do even the simplest things at first the price of power is often paid for by the time and energy it takes to it. For more information on Emacs visit the link above and read the manuals. Books usually can also be found at your local library.
