chrome_clipboard

Please note: This extension now uses the contents service of IPython 3.x currently under development. If you really need to use it with IPython 2.x, you will need to get an older version of this extension from Github. As the older version was really an unsafe hack, please don't.

Description

This IPython notebook extension adds system clipboard actions for single or multiple cells. It allows cut/copy/paste operation of notebook cells and images. Images will be saved to the directory where the current notebook sits. There is currently no way to embed images in markdown cells, due to the google-caja sanitizer used to prevent malicous code execution.

Multi-cell operation is possible using the rubberband extension from this repository.

This extension works only for Chrome, as other browsers do not expose the system clipboard to Javascript.

Hotkey	Function
CTRL+C	Copy cell to system clipboard
CTRL+X	Cut cell and copy to system clipboard
CTRL+V	Paste cell or image from system clipboard

Installation

From IPython simply call

import IPython
IPython.html.nbextensions.install_nbextension('https://github.com/ipython-contrib/IPython-notebook-extensions/raw/master/usability/chrome_clipboard.js')

Then load the extension from within the IPyton notebook:

%%javascript
IPython.load_extensions('chrome_clipboard');

Alternatively, you can add the load command to your custom.js. Take a look at the general installation instructions in the Wiki if you are unsure how to proceed.

This extension was tested using Windows and Chrome. Feedback and improvements are welcome.

Internals

Regarding copying notebook cells over the clipboard, they are stored as mime-type notebook-cell/json.
