Emacs Word Wrap

Real word wrapping in emacs isn't automatic, but here's how it can be done. I found these instructions at http://lispy.wordpress.com/2007/07/12/dark-secrets-of-emacs-word-wrapping/. It's not perfect; despite the comments on that website, I don't yet know how to make word-wrap work after vertical splitting. First, get longlines.el and put it somewhere. Then, add the following lines to your .emacs:

(load "/path/to/longlines.el" t t)
(autoload 'longlines-mode "longlines.el" "Minor mode for editing long lines." t)
;; Uncomment the next line to wrap by default in text mode
;;(add-hook 'text-mode-hook 'longlines-mode)

To activate manually, do M-x longlines. More info at http://www.emacswiki.org/cgi-bin/wiki/LongLines.

Adding An Emacs Menu

Here's some template code for adding a menu item to the main emacs menu bar. I don't know hos this works; I just use it as a template!

;;;;;;; Add items to menu bar
(modify-frame-parameters (selected-frame) '((menu-bar-lines . 2)))
;; Make a menu keymap (with a prompt string)
;; and make it the menu bar item's definition.
(define-key global-map [menu-bar MyMenu] (cons "MyMenu" (make-sparse-keymap "MyMenu")))
;; Define specific subcommands in this menu.
(defun MyMenu-linkify() (interactive) (replace-regexp "^\\(.*\\)$" "\\1
"))
(define-key global-map
  [menu-bar MyMenu linkify]
  '("Linkify" . MyMenu-linkify))
(define-key global-map
  [menu-bar MyMenu truncate]
  '("Truncate em" . toggle-truncate-lines))
