==安装el-get插件管理器==
<pre>
手动把插件下载下来安装插件的过程费时费力，所以使用el-get来管理和安装插件，就像使用Debian/Ubuntu时使用的apt一样，安装软件省时省力。

 编辑~/.emacs文件，加入如下内容：

(add-to-list 'load-path "~/.emacs.d/el-get/el-get")

(unless (require 'el-get nil 'noerror)
  (with-current-buffer
      (url-retrieve-synchronously
       "https://raw.github.com/dimitri/el-get/master/el-get-install.el")
    (goto-char (point-max))
    (eval-print-last-sexp)))

(el-get 'sync)


(add-hook 'python-mode-hook 'jedi:setup)
(setq jedi:complete-on-dot t)
;;    保存，随后启动Emacs，它会自动安装el-get；这个过程可能会比较长，不过我在公司试了 不算慢 毕竟 上了github.com的
</pre>

=== trouble ===
<pre>
emacs --debug-init

Debugger entered--Lisp error: (error "Could not create connection to raw.github.com:443")


解决办法  在另外一台可以的机器全同步就行啦 
rsync  -avz .emacs evan@192.168.0.186:/home/evan/
rsync  -avz .emacs.d/  evan@192.168.0.186:/home/evan/.emacs.d/
</pre>

==安装jedi ==
<pre>
按照官网说法，jedi是一个用于IDE和调试器的Python静态分析工具；之前我们安装了el-get，因此安装jedi就轻松许多，在Emacs下键入（其中『RET』表示回车）：
也就是要回车两次   第一次回车后出现 Install package:  输入 软件名 jedi 再回车

M-x el-get-install RET jedi RET


如果el-get 不然 就用 
M-x package-install RET jedi RET or


如果没有安装virtualenv，请在终端中使用pip安装：

 pip install virtualenv

最后在Emacs中键入：
 M-x jedi:install-server
</pre>

==基本配置加强==

  (add-to-list 'auto-mode-alist '("\\.py\\'" . python-mode))
  (hs-minor-mode t)                     ;开启 hs-minor-mode 以支持代码折叠
  (auto-fill-mode 0)                    ;关闭 auto-fill-mode，拒绝自动折行
  ;(whitespace-mode t)                   ;开启 whitespace-mode 对制表符和行为空格高亮
  ;(hl-line-mode t)                      ;开启 hl-line-mode 对当前行进行高亮
  (pretty-symbols-mode t)               ;开启 pretty-symbols-mode 将 lambda 显示成希腊字符 λ
  (set (make-local-variable 'electric-indent-mode) nil)) ; 建议不要关闭，  关闭自动缩进
  )


(add-hook 'python-mode-hook 'my-python-mode-config)
;jq
</pre>

==trouble ==
Can’t guess python-indent-offset, using defaults: 4

https://segmentfault.com/q/1010000000266278

https://www.cnblogs.com/wangxiaole/articles/7643029.html

在家里如下   这可以用package普通方法安装

Warning (initialization): An error occurred while loading ‘/home/evan/.emacs’:

error: Could not create connection to raw.github.com:443
看来要ss

=00用这个=
<pre>
Usage
回车是 自动补   ctrl+n 才是另起一个新行 没格式关联的
#notice 这个有个问题  第一个func 和第二个func时 会多出4个空格 为什么 呢 


https://github.com/gabrielelanaro/emacs-for-python

最省力的安装是，直接安装别人整合好的一个配置emacs-for-python 
cd  ~/.emacs.d/
git  clone https://github.com/gabrielelanaro/emacs-for-python.git

直接下载下来，并在.emacs文件中添加： 

(load-file "~/.emacs.d/emacs-for-python/epy-init.el")  

;;配置代码错误检测，添加： 
(epy-setup-checker "pyflakes %f")  


vim  ~/.emacs.d/emacs-for-python/epy-init.el

;; 添加显示行号 试过 这个一定有效果
(global-linum-mode 1)




哈哈
不过我觉得还是自己一个个安装比较好，不然哪天来个emacs-for-clojure，后天在来个emacs-for-ruby之类的难保里面的package没有重复冲突的
