1 import readline,rlcompleter
2
3 ### Indenting
4 class TabCompleter(rlcompleter.Completer):
5     """Completer that supports indenting"""
6     def complete(self, text, state):
7         if not text:
8             return ('    ', None)[state]
9         else:
10             return rlcompleter.Completer.complete(self, text, state)
11
12 readline.set_completer(TabCompleter().complete)
13
14 ### Add autocompletion
15 if 'libedit' in readline.__doc__:
16     readline.parse_and_bind("bind -e")
17     readline.parse_and_bind("bind '\t' rl_complete")
18 else:
19     readline.parse_and_bind("tab: complete")
20
21 ### Add history
22 import os
23 histfile = os.path.join(os.environ["HOME"], ".pyhist")
24 try:
25     readline.read_history_file(histfile)
26 except IOError:
27     pass
28 import atexit
29 atexit.register(readline.write_history_file, histfile)
30 del histfile
　　二.windows 方法
　　为进行相关测试.
　　三.常用linux方法
　　1. 下载readline模块
　　http://newcenturycomputers.net/projects/readline.html
　　2. install readlinemodule
　　3. edit and configure pythonstartup file



# 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

　　4. add the enviroment varable to system with administrator role
　　For windowns
　　pythonstartupf=path/pythonstartup.py
　　For Linux
　　add the following to you ~/.bash_profile

export PYTHONSTARTUP=~/.pythonstartup
