good Jedi.el - Python auto-completion for Emacs
安装el-get插件管理器
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
trouble
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 [email protected]:/home/evan/ rsync -avz .emacs.d/ [email protected]:/home/evan/.emacs.d/
安装jedi
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
基本配置加强
; place on ~/.emacs
(defun my-python-mode-config ()
(setq python-indent-offset 4
python-indent 4
indent-tabs-mode nil
default-tab-width 4
;; 设置 run-python 的参数

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

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
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
