Python 自动补全模块 readline 解析

readline模块定义了一系列函数用来读写Python解释器中历史命令，并提供自动补全命令功能。这个模块可以通过relcompleter模块直接调用，模块中的设置会影响解释器中的交互提示，以及内置函数raw_input()和input()提供的提示。
readline模块定义了以下方法： 输入 readline. 然后按 TAB 就能自动补全显示

从项目 https://github.com/hongwenjun/pyreadline 下载源码包，修改替换两个文件，达到不报错误的功效

python windows 安装 readline 模块

python -m pip install pyreadline
# 不能直接用pip install pyreadline

Python 交互模式 历史命令、清屏和调用Shell模块

• 源码: git.io/me.py

  :: Usage:  python -i me.py     or [import me] , import the module me.py
  :: Function:  cls()  ls()  cd(path)  cat(file)  pwd()  bash()  info()  history()

pyreadline

The pyreadline package is a python implementation of GNU readline functionality
it is based on the ctypes based UNC readline package by Gary Bishop.
It is not complete. It has been tested for use with windows 2000 and windows xp.

Version 2.0 runs on Python 2.6, 2.7, and >3.2 using the same code.

Features:

• keyboard text selection and copy/paste
• Shift-arrowkeys for text selection
• Control-c can be used for copy activate with allow_ctrl_c(True) in config file
• Double tapping ctrl-c will raise a KeyboardInterrupt, use ctrl_c_tap_time_interval(x)
  where x is your preferred tap time window, default 0.3 s.
• paste pastes first line of content on clipboard.
• ipython_paste, pastes tab-separated data as list of lists or numpy array if all data is numeric
• paste_mulitline_code pastes multi line code, removing any empty lines.

The latest development version is always available at the IPython git
repository_.
