I understand the code again :-) I'll update the docstring soon. This works for me on Ubuntu, but not on Windows. I'll investigate, but it's good to know that it's working for me. Recent revs allow the @jupyter node to contain the actual json from the .ipynb file. Edward -- You received this message because you are subscribed to the Google Groups "leo-editor" group.

Re: Using Holoview in @Jupyter Nodes
I have only done this for a notebook located on my own computer. You have
to use "file:///" and I changed the backslashes (I'm on Windows) to forward
slashes:
file:///C:/Users/tom/holoview_tests.ipynb
The right syntax for a file URL seems to confuse people. I think the RFCs
aren't too clear. "file:///" is correct - the protocol is "file", and
there is no server (so "//server/" becomes "///"). But many programs want
you to use "file:/c:/..."), and there can be other variants. I just try
all the combinations I can think of until one of them works.
Just as a reminder, this is using VR, *not* VR2.

Many thanks for this. I had completely forgotten that the VR plugin
supports @jupyter nodes! Sheesh. gitk tells me I wrote this on 2017-01-05.
There is nothing in the docstring about @jupyter. Thomas, what do you
paste into the body text? A url, json or html? Anything you can add will
find it's way into the docstring.

P.S. For my reference, the update_jupyter method does the rendering: Here
is the guts of the code:
import nbformat
from nbconvert import HTMLExporter
from urllib.request import urlopen
...
url = g.getUrlFromNode(c.p)
if url and nbformat:
s = urlopen(url).read().decode()
try:
nb = nbformat.reads(s, as_version=4)
e = HTMLExporter()
(s, junk_resources) = e.from_notebook_node(nb)
except nbformat.reader.NotJSONError:
# Assume the result is html.
pass
elif url:
s = 'can not import nbformt: %r' % url
else:
s = g.u('')
w.setHtml(s)
