[IPython-dev] loading a static JS file when loading an IPython extension in the notebook

Here's the most recent thread on that:
http://python.6.x6.nabble.com/Loading-nbextension-on-widget-instantiation-tt5060760.html#none
I captured some of the pattens into a cookiecutter template:

You can use this pattern, even if you aren't using widgets, though.
The key chores are:
- make sure your static files, in a folder, get copied on install
(MANIFEST.in)
- when you are ready to use your JS, copy static into the
nbextensions directory
(in the users profile) with IPython.html.nbextensions.install_nbextension
- display them (and/or any css) with display
Here is the file I use for encapsulating those steps:
https://github.com/bollwyvl/cookiecutter-ipython-widget/blob/master/%7B%7Bcookiecutter.repo_name%7D%7D/%7B%7Bcookiecutter.pkg_name%7D%7D/widgets/mixins.py
It gets called each time an instance of a class is instantiated. It was
suggested that this is preferable over loading it at import time.
Hope this helps!
