如何：在IPython / Jupyter笔记本中进行Sublime Text样式编辑

So, I really like the Jupyter notebook (formerly known as the IPython notebook), but I often find myself missing the ‘fancy’ features that ‘proper’ editors have. I particularly miss the amazing multiple cursor functionality of editors like Sublime Text and Atom.

因此，我真的很喜欢Jupyter笔记本（以前称为IPython笔记本），但是我经常发现自己缺少“适当”编辑者具有的“精美”功能。我尤其想念Sublime Text和Atom之类的编辑器惊人的多光标功能。

I’ve known for a while that you can edit a cell in your default $EDITOR by running %%edit at the top of the cell – but I’ve recently found out that you can configure Jupyter to use Sublime Text-style keyboard shortcuts when editing cells in the notebook – all thanks to CodeMirror, the javascript-based text editor component that the Jupyter notebook uses. Brilliantly, this also brings with it the multiple-cursor functionality! So, you can get something like this:

我已经知道一段时间了，您可以通过在单元格顶部运行%%edit默认$EDITOR中的单元格-但是我最近发现您可以将Jupyter配置为使用Sublime Text样式的键盘快捷键在笔记本中编辑单元格时–多亏了CodeMirror ，Jupyter笔记本使用的基于JavaScript的文本编辑器组件。出色的是，这还带来了多光标功能！因此，您可以获得以下内容：

So, how do you do this? It’s really simple.

那么，你如何做到这一点？真的很简单。

Find your Jupyter configuration folder by running jupyter --config-dir
Open the custom.js file in the custom sub-folder in your favourite editor
Add the following lines to the bottom of the file

通过运行jupyter --config-dir查找Jupyter配置文件夹
在您喜欢的编辑器中的custom子文件夹中打开custom.js文件
将以下行添加到文件的底部

require(["codemirror/keymap/sublime", "notebook/js/cell", "base/js/namespace"],
    function(sublime_keymap, cell, IPython) {
        // setTimeout(function(){ // uncomment line to fake race-condition
        cell.Cell.options_default.cm_config.keyMap = 'sublime';
        var cells = IPython.notebook.get_cells();
        for(var c=0; c< cells.length ; c++){
            cells.code_mirror.setOption('keyMap', 'sublime');
        }

        // }, 1000)// uncomment  line to fake race condition 
    } 
);
