python - `set editing-mode vi` in Python readline (os x)

Question

Trying to beef up my regular python console, I wanted to add vi-style editing.

1st thing: python is not reading ~/.inputrc if I understand well.

Then, I tried to do (through ~/.pythonrc.py):

import readline
readline.parse_and_bind('set editing-mode vi')

Nothing's happening. Did I miss something? Or is it a problem with my terminal?

I'm on OS X using Terminal.app

(tried rlwrap with no success)

Apple 提供的 OS X 系统 Python 中的readline模块不与 GNUreadline库链接，因为 Apple 没有readline随 OS X 一起提供 GNU（可能是因为许可证问题）。它们确实与 BSDeditline库链接，该库libedit读取~/.editrc并支持一组不同的编辑命令。详情请参阅man 5 editrc。如此处所述，您可以检查其中的文本libedit以readline.__doc__确定使用的是 GNUreadline还是 BSD editline。如果你真的需要 GNU readline，你可以readline从 PyPI 安装包，readline它有一个与 GNU 链接的 Python 模块的预编译版本readline。
