Emacs Again (2): auto-save and font

Auto save revisited

So I joined irc.freenode.net#emacs, and asked how to configure auto-save. Several nice people helped me out. Here’s my .emacs.el for backup and auto-save.

(setq make-backup-files t)       ; enable backup file
;;; locate where you backup files
(setq backup-directory-alist
      (cons (cons "\\.*$" (expand-file-name "~/.backup"))
            backup-directory-alist))

(setq version-control t)     ; enable versions of backup
(setq kept-new-versions 5)   ; how many keep new verisons
(setq kept-old-versions 5)   ; how many keep old versions
(setq delete-old-versions t) ; delete old version without asking
(setq vc-make-backup-files t) ; still make a backup for version-controled files                

;;; Autosave in .backup dir
(setq auto-save-file-name-transforms
  '(("\\([^/]*/\\)*\\([^/]*\\)\\'" "~/.backup/\\2" t)))

Originally, I was very confused by auto-save and backup. FIles of backup are named usually like FILE_NAME~ and autosave are like #FILE_NAME#. At this point, I’m not quite sure that auto-save-file-name-transforms will take, but that’s alright. What I wanted to d

Japanese (or other multibyte)

Me as a native Japanese speaker, I often times, use Japanese Characters, plus I learned Chinese these days, I may have chances to read and write in Chinese Characters as well. Here’s what I use now for Japanese language. They are all copied from some of XEmacs distribution package I guess. It’s still just a magic spells…

;; ============= Japanese language setting ======================

  (set-language-info "Japanese" 'input-method "MacOSX") ;; bad fix
  ;; input method in read-only buffer (e.g. C-s in dired-mode)
  (setq mac-pass-key-to-system-on-read-only-buffer t)
  )
;; A. end

Font for Terminal

And for terminal font, I really appreciate Droid Sans Mono. Droid Family is designed for Google’s Android.

Download the Android SDK

Unzip the archive, and you’ll find .ttf files under tools/lib/fonts/default/. what it’s cool about is, very readable with small font size, mono space and comes with CJK typeface as well. License-wise, maybe ok for your personal use, you can at least develop Android with this. Small note: Android SDK comes with Android.el as well.
