IPython shell的换行问题 [英] Line-wrapping problems with IPython shell

问题描述

如果我在IPython中运行了很长的一行，并尝试在当前行的开头之外调用它（使用向上箭头）或退格，则显示不正确（全部被刷成一行）

If I have run a long line in IPython, and try and recall it (using the up-arrow) or backspace beyond the start of the current line, it displays incorrectly (all smushed into one line)

例如，在下面的会话中我写了一个长行 [1] ，输入了一个空白的行 [2] ，然后向上箭头两次以获取 [3] [3] print 语句$ c>，发生以下情况：

For example, in the following session I wrote a long line [1], entered a somewhat-blank line [2], then up-arrowed twice to get the print statement on line [3], and the following happened:

在iTerm和Terminal.app中都有发生。我在常规终端会话中遇到了类似的问题，通过正确终止颜色代码来修复，但是我我不知道如何用IPython修复它

Happens in both iTerm and Terminal.app.. I had a similar problem with regular terminal sessions, which was fixed by properly terminating colour codes, but I'm not sure how to fix it with IPython

推荐答案

啊哈！我有一个旧版本的Python readline模块 - 从 http://ipython.scipy.org/dist安装最新版本/ 它完美无缺！

Aha! I had an old version of the Python readline module - installing the latest from http://ipython.scipy.org/dist/ and it works perfectly!

sudo easy_install http://ipython.scipy.org/dist/readline-2.5.1-py2.5-macosx-10.5-i386.egg
