Starter Kit Misc

Things that don’t fit anywhere else.

Color Themes

The Color Themes package provides support for changing, saving, sharing Emacs color themes. To view and apply color themes available on your system run M-x color-theme-select. See the color theme website and EmacsWiki pages for more information.

This following loads color-theme so that it is available by default.

(add-to-list 'load-path
             (expand-file-name "color-theme"
                               (expand-file-name "src" dotfiles-dir)))
(require 'color-theme)
(eval-after-load "color-theme"
  '(progn
     (color-theme-initialize)))

Once you’ve selected a preferred color theme it can be installed by adding its function to your initialization. For example

(color-theme-railscasts)

will load the railscasts color theme when Emacs starts.

possible issues/resolutions with flyspell

Most of the solution came from EmacsWiki-FlySpell. Here is one possible fix.

Emacs set path to aspell

it’s possible aspell isn’t in your path

(setq exec-path (append exec-path '("/opt/local/bin")))

Emacs specify spelling program

  • This didn’t work at first, possibly because cocoAspell was building its dictionary. Now it seems to work fine.
(setq ispell-program-name "aspell"
      ispell-dictionary "english"
      ispell-dictionary-alist
      (let ((default '("[A-Za-z]" "[^A-Za-z]" "[']" nil
                       ("-B" "-d" "english" "--dict-dir"
                        "/Library/Application Support/cocoAspell/aspell6-en-6.0-0")
                       nil iso-8859-1)))
        `((nil ,@default)
          ("english" ,@default))))

Hippie expand: at times perhaps too hip

(delete 'try-expand-line hippie-expand-try-functions-list)
(delete 'try-expand-list hippie-expand-try-functions-list)

Don’t clutter up directories with files~

(setq backup-directory-alist `(("." . ,(expand-file-name
                                        (concat dotfiles-dir "backups")))))

Associate modes with file extensions

(add-to-list 'auto-mode-alist '("COMMIT_EDITMSG$" . diff-mode))
(add-to-list 'auto-mode-alist '("\\.css$" . css-mode))
(add-to-list 'auto-mode-alist '("\\.ya?ml$" . yaml-mode))
(add-to-list 'auto-mode-alist '("\\.rb$" . ruby-mode))
(add-to-list 'auto-mode-alist '("Rakefile$" . ruby-mode))
(add-to-list 'auto-mode-alist '("\\.js\\(on\\)?$" . js2-mode))
;; (add-to-list 'auto-mode-alist '("\\.xml$" . nxml-mode))

Default to unified diffs

(setq diff-switches "-u")

Cosmetics

(eval-after-load 'diff-mode
  '(progn
     (set-face-foreground 'diff-added "green4")
     (set-face-foreground 'diff-removed "red3")))

(eval-after-load 'magit
  '(progn
     (set-face-foreground 'magit-diff-add "green3")
     (set-face-foreground 'magit-diff-del "red3")))
