Vim 编辑器 - zsh shell ipython magic %ed 找不到编辑器

Question

我正在尝试使用 IPython 中的 %ed 魔法来使用 vim 作为编辑器。

vim 已安装
ipython 和 ipython qtconsole 都可以工作
zsh 是最新的，随着我的 oh-my-zsh 安装更新

我将我的偏好导出到 zsh

$ echo "export EDITOR=/usr/bin/vim" >> ~/.zshrc

$ echo "export VISUAL=/usr/bin/vim" >> ~/.zshrc

但是，当我启动 IPython 然后调用 %ed 魔法时，它失败了

In [1]: %ed
IPython will make a temporary file named: /tmp/ipython_edit_pu4Yql.py
Editing.../bin/sh: 1: mvim: not found
WARNING: Could not open editor

如何让它工作？

Answer 1

尝试使用 IPython 的配置文件配置作为指定编辑器的方法。为此：

首先，生成默认配置文件：

$ ipython profile create

接下来，找到要编辑的 ~/.ipython/profile_default/..._config.py 文件。例如 IPython 2.4.1,

$ vim ~/.ipython/profile_default/ipython_config.py

找到注释掉的.editor设置，取消注释，设置为vim。例如在 IPython 2.4.1 中，这看起来像

c.TerminalInteractiveShell.editor = 'vim'

你现在会发现当你启动IPython时，你可以%ed它会调用vim:

$ ipython
Python 2.7.11+ (default, Feb 22 2016, 16:38:42)
Type "copyright", "credits" or "license" for more information.

说明

man ipython:

FILES

IPython uses various configuration files stored in profiles within IPYTHONDIR. To generate the default configuration files and start configuring IPython, do 'ipython profile create', and edit '*_config.py' files located in IPYTHONDIR/profile_default.

IPYTHONDIR 根据 man ipython:

IPYTHONDIR

This is the location where IPython stores all its configuration files. The default is $HOME/.ipython if IPYTHONDIR is not defined.

You can see the computed value of IPYTHONDIR with ipython locate.

我还提到了版本，因为某些版本的设置似乎有所不同，对于 2.4.1，设置称为：

c.TerminalInteractiveShell.editor = ...

而在 IPython setting text editor 给出的答案中，此设置的名称不同：

c.IPythonWidget.editor = ...

由于版本之间似乎有所不同，生成默认配置文件后，请查看它在您的IPython版本中是如何编写的，并据此进行操作。
