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】

1. [~$]python
2. Python 2.7.3 (default, Apr 10 2013, 06:20:15)
3. [GCC 4.6.3] on linux2
4. Type "help", "copyright", "credits" or "license" for more information.
5. >>> import sys
6. >>> sys.path
7. [‘‘, ‘/usr/lib/python2.7‘, ‘/usr/lib/python2.7/plat-linux2‘, ‘/usr/lib/python2.7/lib-tk‘, ‘/usr/lib/python2.7/lib-old‘,
8. ‘/usr/lib/python2.7/lib-dynload‘, ‘/usr/local/lib/python2.7/dist-packages‘, ‘/usr/lib/python2.7/dist-packages‘,
9. ‘/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‘,
10. ‘/usr/lib/python2.7/dist-packages/ubuntu-sso-client‘, ‘/usr/lib/python2.7/dist-packages/ubuntuone-client‘,
11. ‘/usr/lib/python2.7/dist-packages/ubuntuone-control-panel‘, ‘/usr/lib/python2.7/dist-packages/ubuntuone-couch‘,
12. ‘/usr/lib/python2.7/dist-packages/ubuntuone-installer‘, ‘/usr/lib/python2.7/dist-packages/ubuntuone-storage-protocol‘]
13. >>>

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

[python]

1. #!/usr/bin/python
2. # python startup file
3. import sys
4. import readline
5. import rlcompleter
6. import atexit
7. import os
8. # tab completion
9. readline.parse_and_bind(‘tab: complete‘)
10. # history file
11. histfile = os.path.join(os.environ[‘HOME‘], ‘.pythonhistory‘)
12. try:
13. readline.read_history_file(histfile)
14. except IOError:
15. pass
16. atexit.register(readline.write_history_file, histfile)
17. del os, histfile, readline, rlcompleter

3.切换至自己主目录

[plain]

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

4. 增加环境变量

[plain]

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

5.配置环境变量生效

[plain] 

1. [~$]source .bashrc

PYTHONSTARTUP是什么东西呢？

[plain] view plaincopyprint?

1. If this is the name of a readable file, the Python commands in that file are executed before the first prompt
2. is displayed in interactive mode.  The file is executed in the same name space where interactive commands are
3. executed so that  objects defined  or  imported in it can be used without qualification in the interactive session.
4. 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

[plain] view plaincopyprint?

1. unzip  pydiction-1.2.1.zip
2. cp python_pydiction.vim  /usr/share/vim/vim73/ftplugin
3. mkdir  /usr/share/vim/vim73/pydiction
4. cp complete-dict  /usr/share/vim/vim73/pydiction/
5. cp pydiction.py  /usr/share/vim/vim73/pydiction/

3.修改vim配置文件

[plain] view plaincopyprint?

1. let g:pydiction_location = ‘/usr/share/vim/vim73/pydiction/complete-dict‘
2. let g:pydiction_menu_height = 20

OK，测试是否生效吧
