python的tab自动补全

vim tab.py

#!/usr/bin/env 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



代码有了，我们还需要将脚本放到python指定的目录下，可以使用sys.path来查看一下

>>> sys.path
['', '/usr/lib/python2.6/site-packages/pip-7.1.2-py2.6.egg', '/usr/lib64/python26.zip', '/usr/lib64/python2.6', '/usr/lib64/python2.6/plat-linux2', '/usr/lib64/python2.6/lib-tk', '/usr/lib64/python2.6/lib-old', '/usr/lib64/python2.6/lib-dynload', '/usr/lib64/python2.6/site-packages', '/usr/lib64/python2.6/site-packages/gtk-2.0', '/usr/lib/python2.6/site-packages', '/usr/lib/python2.6/site-packages/setuptools-0.6c11-py2.6.egg-info']

 一般我们会将这一类代码放在/usr/local/lib/python2.7/dist-packages目录下

 

mv tab.py /usr/local/lib/python2.6/dist-packages

ok，下面我们可以直接导入tab模块
