Render Jupyter notebook in tree

[Katsuya Horiuchi]

Thanks for your input, Hugo.
I put the following block to syntax-highlighting.py and it worked:

----------
import subprocess

if filename[-6:] == '.ipynb':
    cmd = subprocess.Popen(
        'jupyter-nbconvert --stdin --to html --stdout',
        shell=True,
        stdin=subprocess.PIPE,
        stdout=subprocess.PIPE
    )
    stdout, _ = cmd.communicate(input=data.encode('utf-8'))
    if stdout:
        sys.stdout.write('''
</code></pre></td></tr></table>
<style>
        .blob { display: none; }
</style>
''')
        sys.stdout.write("<div>")
        sys.stdout.write(stdout.decode('utf-8'))
        sys.stdout.write("</div>")
        sys.stdout.write("<table class='blob'><tr><td><pre><code>")
        sys.exit(0)

----------

If converting notebook to html doesn't work for whatever reason,
nothing will happen.
Anyone thinks this is too complex to add to the default filter?


Best,
K
