My Emacs Setting on Servers

My desktop emacs config is complecated, however I need a minimal config for emacs installed on ubuntu servers. This is my note of how to configure emacs on servers that works for me.

Emacs24

First, I need to get Emacs24 installed on ubuntu, which is not by default. This link Install Emacs 24 in Ubuntu is a great guide of how to install emacs 24. Here are the commands you need to type:

1
2
3

sudo add-apt-repository ppa:cassou/emacs
sudo apt-get update
sudo apt-get install emacs24

Configure Packges Archives

With Emacs 24, you can use the package managing system easily. Open your ~/.emacs file and enter

1
2
3
4

(require 'package)
(add-to-list 'package-archives '("marmalade"."http://marmalade-repo.org/packages/"))
(add-to-list 'package-archives '("melpa"."http://melpa.milkbox.net/packages/") t)
(package-initialize)

Save the file, and M-x eval-buffer, then M-x package-refresh-contents. Now you’re ready to install most of the emacs plugins.

Plugins I installed

  1. Paredit.el: a mode for editing structured s-expressions, very useful for lisp based programs including emacs-lisp and clojure.

  2. clojure mode: mode for editing clojure files

  3. Ace Jump: Move your cursor to where you eyes are looking at.

;; it's dangerous to keep backup files in the same directory on the server
(setq backup-directory-alist '(("." . "~/.backup_emacs"))
      auto-save-file-name-transforms '((".*" "~/.backup_emacs" t))
      backup-by-copying t    ; Don't delink hardlinks
      version-control t      ; Use version numbers on backups
      delete-old-versions t  ; Automatically delete excess backups
      kept-new-versions 20   ; how many of the newest versions to keep
      kept-old-versions 5    ; and how many of the old
)

;; configure paredit
(add-hook 'clojure-mode-hook (lambda () (paredit-mode 1)))
(add-hook 'emacs-lisp-mode-hook (lambda () (paredit-mode 1)))

;; auto complete for emacs lisp
(setq tab-always-indent 'complete)
(add-to-list 'completion-styles 'initials t)
(define-key global-map (kbd "RET") 'newline-and-indent)

;; ace jump mode
(global-set-key (kbd "<ESC><ESC>") 'ace-jump-mode)

Hope these helps :D
