updating file tree in "extending notebook" section

[choldgraf]

I was going through the "extending the notebook" section and noticed that there's a file tree that's being rendered incorrectly which is a bit confusing. This cleans that up.

Here's the page w/ the bug now: https://jupyter-notebook.readthedocs.io/en/latest/examples/Notebook/Distributing%20Jupyter%20Extensions%20as%20Python%20Packages.html#Automatically-enabling-a-server-extension-and-nbextension

While I'm at it, is it possible to automatically activate a bundler w/ install in the same way following these instructions? They seem to be scoped for nbserver / notebook extensions only

I think the same thing should apply for bundler extensions. @parente?

Haven't tested to see if bundler extensions can be activated the same way. I suspect it'll "just work" since they derive from the same extension config base classes.

/me makes a note to try sometime

@parente if you could give me a free-form set of steps to try, I can give it a shot and see if it works, and if so, can make a PR to the docs for this...

Took a quick peek to refresh my memory. Doesn't look like it works today. I ran the classic commands near the bottom of https://jupyter-notebook.readthedocs.io/en/stable/extending/bundler_extensions.html to enable the zip bundler included in the notebook package.

jupyter bundlerextension enable --py notebook.bundler.zip_bundler --sys-prefix

This wrote a JSON file in $PREFIX/etc/jupyter/nbconfig/notebook.json with content:

{
  "bundlerextensions": {
    "notebook_zip_download": {
      "label": "IPython Notebook bundle (.zip)",
      "module_name": "notebook.bundler.zip_bundler",
      "group": "download"
    }
  }
}

Moving that JSON file to $PREFIX/etc/jupyter/jupyter_notebook_config.d/zip_bundler.json didn't appear to work. jupyter bundlerextension list shows nothing and I don't see the menu item when I fire up jupyter notebook.

Maybe the JSON config structure needs to change? Maybe we need a traitlet like for bundlers

notebook/notebook/notebookapp.py

Line 1254 in cf1b7b3

nbserver_extensions = Dict({}, config=True,

?

hmmm - I'm gonna pop this off into an issue :-)
