标题：如何配置emacs python 开发环境?

小包

楼主 2010年05月28日星期五 20:27

如题,我来给大家讲下如何配置!

我只是介绍工具,不会深入到代码如何实现,因为,我只是利用它而已,况且想要讲代码,那是不可能的......因为,很多人可能没学过LISP等语言..........

开始吧,

下载pymacs，解压到任意一个目录中，如:我的是[B.Qnyd@localhost 下载]$ ls -l

将会看见pymacs 的python代码源包,解压就行了....

进入其中执行 python setup.py install 可以先执行python setup build 然后安装rope ropemacs来很好的配合python让他具有IDE的项目管理功能,首先执行下面的命令下载源代码下来

 
  $
  
   hg clone http:/
  
 
 
  
   /
  
  
   bitbucket
  
  
   .
  
  
   org
  
  
   /
  
  
   agr
  
  
   /
  
  
   rope
  
  
   /
  
 
 
  

  $
  
   hg clone http
  
 
 
  
   :
  
  
   //bitbucket.org/agr/ropemacs/
  
 
 
  

  $
  
   hg clone http
  
 
 
  
   :
  
  
   //bitbucket.org/agr/ropemode/
  
 
 
  

  

  然后分别进入rope ropemacs 里面执行
 
 
  python setup.py install
  

 
 
  

  把三个文件分别移动到你的path下面如:
  
   mv rope* /home/B.Qnyd/lisp/
   
    

    如果你还想要它检查你的语法是否正确,你就需要安装pyflakes
    

    我的是fedora 直接安装
    
     yum install pyflakes
    
    

    其他系统可以用sudo apt-get install 等系统默认的在线安装包...
    

    (
    
     注意这个python-setuptools东西必不可少,一样执行
    
    yum install python-setuptools)
    

    然后.
    

    新建一个pymacs-settings.el 把以下代码加入进去:
    

    

    
     (setq pymacs-load-path '("~/lisp/rope"
     

     "~/lisp/ropemacs"))
     

     (autoload 'python-mode "python-mode" "Python Mode." t)
     

     (add-to-list 'auto-mode-alist '("\\.py\\'" . python-mode))
     

     (add-to-list 'interpreter-mode-alist '("python" . python-mode))
     

     (require 'python-mode)
     

     (add-hook 'python-mode-hook
     

     (lambda ()
     

     (set-variable 'py-indent-offset 4)
     

     ;(set-variable 'py-smart-indentation nil)
     

     (set-variable 'indent-tabs-mode nil)
     

     (define-key py-mode-map (kbd "RET") 'newline-and-indent)
     

     ;(define-key py-mode-map [tab] 'yas/expand)
     

     ;(setq yas/after-exit-snippet-hook 'indent-according-to-mode)
     

     

     ))
     

     ;; pymacs
     

     (autoload 'pymacs-apply "pymacs")
     

     (autoload 'pymacs-call "pymacs")
     

     (autoload 'pymacs-eval "pymacs" nil t)
     

     (autoload 'pymacs-exec "pymacs" nil t)
     

     (autoload 'pymacs-load "pymacs" nil t)
     

     ;;(eval-after-load "pymacs"
     

     ;;  '(add-to-list 'pymacs-load-path YOUR-PYMACS-DIRECTORY"))
     

     (pymacs-load "ropemacs" "rope-")
     

     (setq ropemacs-enable-autoimport t)
     

     ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

     (nreverse
     

     (dolist (element list value)
     

     (setq value (cons (format "%s%s" prefix element) value))))))
     

     (defvar ac-source-rope

     (provide 'pymacs-settings)
    
    

   
  
  

  

  然后在你的.emacs 里面加入 (load "pymacs-settings")这样你就给你的emacs扩展了自动补全,
  

  建立工程了.不比任何IDE差...... 不过首先你得配置好,不然你就会觉得它很差劲....
