python <tab>自动补全

一。这个方法可以修改shell命令行的自动补全

1.获取python目录【我使用的是64位ubuntu系统】

• [~$]python  
  
• Python 2.7.3 (default, Apr 10 2013, 06:20:15)   
  
• [GCC 4.6.3] on linux2  
  
• Type "help", "copyright", "credits" or "license" for more information.  
  
• >>> import sys  
  
• >>> sys.path  
  
• ['', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-linux2', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old',   
  
• '/usr/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages',   
  
• '/usr/lib/python2.7/dist-packages/PIL', '/usr/lib/python2.7/dist-packages/gst-0.10', '/usr/lib/python2.7/dist-packages/gtk-2.0',  
  
• '/usr/lib/python2.7/dist-packages/ubuntu-sso-client', '/usr/lib/python2.7/dist-packages/ubuntuone-client',   
  
• '/usr/lib/python2.7/dist-packages/ubuntuone-control-panel', '/usr/lib/python2.7/dist-packages/ubuntuone-couch',   
  
• '/usr/lib/python2.7/dist-packages/ubuntuone-installer', '/usr/lib/python2.7/dist-packages/ubuntuone-storage-protocol']  
  
• >>>   
  
  

从上面看出python在我电脑上的路径是  /usr/lib/python2.7

2.切换至该目录写个startup.py的脚本,脚本目录就是处理python中<tab>事件，脚本内容如下

• #!/usr/bin/python   
  
• # python startup file   
  
•            
  
• import sys   
  
• import readline   
  
• import rlcompleter   
  
• import atexit   
  
• import os   
  
• # tab completion   
  
• readline.parse_and_bind('tab: complete')   
  
• # history file   
  
• histfile = os.path.join(os.environ['HOME'], '.pythonhistory')   
  
• try:   
  
•     readline.read_history_file(histfile)   
  
• except IOError:   
  
•     pass   
  
• atexit.register(readline.write_history_file, histfile)   
  
•            
  
• del os, histfile, readline, rlcompleter  
  
  

3.切换至自己主目录

• [/usr/lib/python2.7$]cd   
  
• [~$]vi .bashrc   
  
  

4. 增加环境变量

• #for python  
  
• export PYTHONSTARTUP=/usr/lib/python2.7/startup.py  
  
  

5.配置环境变量生效

• [~$]source .bashrc   
  
  

PYTHONSTARTUP是什么东西呢？

[plain] view plaincopyprint?

• If this is the name of a readable file, the Python commands in that file are executed before the first prompt   
  
• is displayed in interactive mode.  The file is executed in the same name space where interactive commands are  
  
• executed so that  objects defined  or  imported in it can be used without qualification in the interactive session.   
  
• You can also change the prompts sys.ps1 and sys.ps2 in this file.  
  
  

二。这个方法能在VIM中自动补全

    1. 下载插件:

   2.拷贝致相应的目录

• unzip  pydiction-1.2.1.zip  
  
• cp python_pydiction.vim  /usr/share/vim/vim73/ftplugin  
  
• mkdir  /usr/share/vim/vim73/pydiction  
  
• cp complete-dict  /usr/share/vim/vim73/pydiction/  
  
• cp pydiction.py  /usr/share/vim/vim73/pydiction/  
  
  

   3.修改vim配置文件

• let g:pydiction_location = '/usr/share/vim/vim73/pydiction/complete-dict'  
  
• let g:pydiction_menu_height = 20  
  
  

OK，测试是否生效吧
