My main .emacs just loads other configuration files which I keep in .emacs.d/:

;; set load paths
(add-to-list 'load-path (expand-file-name "~/.emacs.d"))
;; for extra elisp packages
(add-to-list 'load-path (expand-file-name "~/.emacs.d/lisp"))
;; for personal elisp projects
(add-to-list 'load-path (expand-file-name "~/.emacs.d/lisp-personal"))
;; load elisp customisations
(require 'SH-global)
(require 'SH-modes)
(require 'SH-temp)

SH-global.el is (or is supposed to be) for settings that affect everything:

;; global settings
(setq inhibit-startup-message t)
(fset 'yes-or-no-p 'y-or-n-p) ; no yes-or-no prompts
(setq transient-mark-mode t) ; selection coloring and stuff

(setq column-number-mode t)
(toggle-scroll-bar -1) ; no scroll bar
(tool-bar-mode -1) ; no tool bar
(global-font-lock-mode t)
(auto-compression-mode 1) ; when editing compressed files, uncompress first
(setq indent-tabs-mode nil)

  (current-global-map) [remap find-file-other-frame] 'find-file-other-frames)
(provide 'SH-global) ; this tells .emacs that (require 'SH-global) is satisfied

SH-modes.el modifies the behavior of some modes:

;; C family
;; binds enter to newline-and-indent which is normally C-j
;; sets up no-tab indentation and depth 4
(add-hook 'c-mode-common-hook
	    (local-set-key (kbd "RET") 'newline-and-indent)
            (setq indent-tabs-mode nil)

;; Indentation style for C-family code
(setq c-default-style
      '((c++-mode . "stroustrup") (c-mode . "k&r") (java-mode . "java")))
(setq c-basic-offset 4)
(c-set-offset 'innamespace 0)
;; scheme
;; note: there used to be some custom Scheme stuff here,
;; but I've replaced all that by loading quack, an extra package
;; (...or should that somehow *be* the scheme mode?)
(add-hook 'scheme-mode-hook
	     (require 'quack)))
(add-hook 'python-mode-hook
	  '(lambda ()
	     (setq python-indent 4)))
;; a find-file-other-frame for dired
(defun dired-find-file-other-frame ()
  "In dired, visit this file or directory in another frame."
  (find-file-other-frame (dired-get-file-for-visit)))
(setq dired-load-hook
       (lambda ()
	 (define-key dired-mode-map "e" 'dired-find-file-other-frame))))
(provide 'SH-modes)

SH-temp contains temporary highlighting functions and such for ephemeral projects. lisp/ contains:

  • html-helper-mode.el
  • hhm-config.el (configuration for previous)
  • tempo.el (a template package)
  • quack.el (extra support for Scheme)

Which I won’t list here as they exist as distributed packages. There’s also find-file-root.el, which I found in EmacsWiki. It edits a file as root, using sudo and tramp (so those need to be present). There are many obvious improvements, but I’ve been happy with it. If you don’t like the idea of editing as root with your user password (as I don’t), append rootpw to Defaults in your sudoers file.

  (if (featurep 'xemacs) "/[sudo/root@localhost]" "/sudo:root@localhost:" )

  "History list for files found using `find-file-root'.")
(defvar find-file-root-hook nil
  "Normal hook for functions to run after finding a \"root\" file.")
(defun find-file-root ()
  "*Open a file as the root user.
   Prepends `find-file-root-prefix' to the selected file name so that it
   maybe accessed via the corresponding tramp method."

	 ;; use a separate history list for "root" files.

	 (tramp (and (tramp-tramp-file-p name)
