Some tricks from my .emacs:

  (server-start)

  ;; no Tabs
  (setq-default indent-tabs-mode nil)
  (setq-default tabs-width 2)

  ;; List more buffers in the buffer menu
  (setq-default buffers-menu-max-size 30)

  ;; Prevent startup message and switch to empty *scratch*
  (setq inhibit-startup-message t)
  (setq initial-scratch-message nil)

  ;; Fix C&P
  (setq x-select-enable-clipboard t)

  ;; Make Caps Lock LED blink instead of audio bell
  (setq visible-bell 1)
  (setq ring-bell-function
        (lambda ()
          (when (getenv "DISPLAY")
            (call-process-shell-command "xset led named \"Scoll Lock\"; xset -led named \"Scroll Lock\"" nil 0 nil))))

  (show-paren-mode 1)
  (column-number-mode 1)

  ;; Keep the custom stuff separate
  (setq custom-file "~/.emacs.d/custom.el")
  (load custom-file)

  ;; I know what downcase-region does. Me no noob anymore ;). So undisable it.
  (put 'downcase-region 'disabled nil)

  ;; This can be a life saver!
  (push '("." . "~/.emacs.d/backups") backup-directory-alist)

  ;; Create better buffer names. foo.c++:src, foo.c++:extra instead of foo.c++ and foo.c++
  ;; This should really be the default behaviour for Emacs!
  (require 'uniquify)
  (setq 
    uniquify-buffer-name-style 'reverse
    uniquify-separator ":")

  ;; c-mode hook to set better default compile-command if no Makefile exists and activate flyspell-prog-mode
  ;; I have similar hooks for c-mode and fortran-mode
  (add-hook 'c++-mode-hook
          (lambda ()
            (flyspell-prog-mode)
            (unless (or (file-exists-p "Makefile")
                        (local-variable-p 'compile-command)
                        (not buffer-file-name))
              (set (make-local-variable 'compile-command)
                   (format "%s %s %s"
                           (or (getenv "CXX") "g++")
                           (or (getenv "CXXFLAGS")
                               "-pipe -std=c++0x -pedantic-errors -Wall -Wextra -Weffc++ -g3")
                           (file-name-nondirectory buffer-file-name))))))

  ;; Set f9 to compiler and f8 to make clean
  (global-set-key '[f9] 'compile)
  (global-set-key '[f8] '(lambda ()
                          (interactive)
                          (when (file-exists-p "Makefile") (compile "make clean"))))
The rest is just some specific mode setup and minor key bindings stuff.

Funny, about an hour ago I finally broke down and remapped Ctrl+w to backward-kill-word[1] after re-reading Yegge's Effective Emacs, and you've just reminded me to push the commit to my fork of emacs-starter-kit, which is a great way to get a core set of functionality.

I too made the switch after reading Yegge's good stuff, but missed kill-region so badly I had to come up with this:

    (defun backward-kill-word-or-kill-region (&optional arg)
      (interactive "p")
      (if (region-active-p)
    	  (kill-region (region-beginning) (region-end))
    	(backward-kill-word arg)))

    (global-set-key (kbd "C-w") 'backward-kill-word-or-kill-region)
This gets me kill-region for an active (transient-mark-mode) region but backward-kill-word otherwise.

Excellent idea; thanks!

my .emacs is on bitbucket: https://bitbucket.org/zaphar/dotfiles/src/tip/.emacs.d/

Some notable items:

    ;;; allow seperating out the config stuff to 
    ;;; into different files
    (defvar jaw:config-dir (expand-file-name "~/.emacs.d/conf.d")
      "My config parts directory location.")

    (defun jaw:load-confs ()
     "Load Jeremy's config file parts"

Viper mode gives you the best of both worlds, although I'm probably considered a heretic in both religions.

  (setq viper-mode t)
  (require 'viper)

  (custom-set-variables
   '(column-number-mode t)
   '(inhibit-startup-screen t)
   '(show-paren-mode t)
   '(tool-bar-mode nil)
   '(menu-bar-mode nil))
I used to have slime config stuff in there, but now Ubuntu does it all for me. Thanks Ubuntu!

a lot of things, 1376 lines @ http://github.com/cycojesus/emacs

It uses org-babel to keep it organized and readable so really there's a short wrapper init.el that then calls babel-init.org

External packages are installed system-wide using my own .SlackBuild generated packages (@ http://github.com/cycojesus/slackbuilds/tree/master/e/ )

Of course I run Slackware.

If it makes you feel any better, back when I was managing a team in Visual Studio, we called this the "When in Rome" feature. And yes, the versions of this we tried to put together worked as you'd expect... mostly. Determining peoples' whitespace decisions are not trivial. How many lines does the THEN clause of an IF need to have before you surround it with curlies? Do you only put a space before the parens around a function's arguments if there is more than one argument? And my personal favorite, how do you "funge" your indentation style if the nesting level gets high enough that you're at frequent risk of line wrap (soft or hard doesn't matter here)?

People have wacky rules, and as soon as you say you're going to auto-detect them, you're in for a world of pain. Of course, you might have a user base that isn't as persnickety, in which case it's really not that bad.

So you're the other viper-mode user! We should have coffee sometime :)
