config extension

There is now a graphical user interface for activating/deactivating installed notebook extensions by going to the '/nbextensions/' URL:

This is realized using a notebook server extension, new to IPython 3.x. In order to work, this extensions needs to be installed and notebook extensions require a YAML description file in order to be found.

#Setup procedure ##1. Installation All required files are originally located in the 'config' of the repository.

• copy 'main.js' and 'main.css' to your '~/.ipython/nbextensions/config' folder
• copy 'nbextensions.py' to your '~/.ipython/extensions' folder
• copy 'nbextensions.html' to your '~/.ipython/templates' folder

##2. Configuration Add the following lines to your 'ipython_notebook_config.py' file: ''' from IPython.utils.path import get_ipython_dir import os import sys

ipythondir = get_ipython_dir() extensions = os.path.join(ipythondir,'extensions') sys.path.append( extensions )

c = get_config() c.NotebookApp.server_extensions = [ 'nbextensions', 'preview' ] c.NotebookApp.extra_template_paths = [os.path.join(ipythondir,'templates') ] '''

#YAML file format

• Type - identifier 'IPython Notebook Extension'
• Name - unique name of the extension
• Description - short explanation of the extension
• Link - link to more documentation
• Icon - small icon 400px wide
• Main - main file that is loaded, typically 'main.js'
• Compatibility- IPython version compatibility (e.g. 3.x)
