emacs笔记

前言

最初接触emacs是因为org-mode，后来学习lisp又把玩了几把。
我还是无法放弃Lisp，就从emacs开始吧，虽然之前配置过很多次，但都没有很好的记录过。
首先当然是下载了，http://www.gnu.org/software/emacs/，目前最新版是25.2
解压运行runemacs.exe就行，终端下emacs -nw。安装之后我们简要配置一下。

入门配置

参考 http://www.jianshu.com/p/b4cf683c25f3

配置文件及其加载过程：通常，emacs会优先加载.emacs，如果找不到，并且存在文件夹.emacs.d，会尝试加载其中的init.el

HOME路径

===============================================
将如下配置copy到$HOME/.emacs.d，重命名为init.el

;; copy this file to $HOME/.emacs.d/, and rename it to "init.el". (in windows, the default HOME directory is "C:\Users\x\AppData\Roaming", you can find out that by typping "C-x d ~/ " in emacs.)
(setenv "HOME" "C:/emacs") ;; you can change this dir to the place you like

(require 'package)

(add-to-list 'package-archives '("org" . "http://orgmode.org/elpa/"))
(when (< emacs-major-version 24)
  (add-to-list 'package-archives '("gnu" . "http://elpa.gnu.org/packages/")))
(add-to-list 'package-archives '("melpa" . "http://melpa.milkbox.net/packages/"))
(add-to-list 'package-archives '("melpa-stable" . "http://melpa-stable.milkbox.net/packages/"))

(package-initialize)

(load "~/.emacs.d/init.el")

=================================================
接下来的才是正式的配置文件，即~/.emacs.d/init.el，以下为新手配置，大神勿喷。
主要设置外观、字体、编码、tab、缩进等。
