Save and export as html automatically

[skin...@gmail.com]

Hi,

I'm trying to automatically export as html at the end of execution. (i.e. enter some parameters, 'run all' and have an html output).

From searching the group here, I came up with:

%%javascript
Jupyter.notebook.save_notebook();
Jupyter.notebook.kernel.execute("window_loc = '" + window.location + "'")
Jupyter.notebook.kernel.execute("notebook_base = '" + IPython.notebook.base_url + "'")
Jupyter.notebook.kernel.execute("notebook_path = '" + IPython.notebook.notebook_path + "'")

then on the next cell:

filename = 'outout.html'
from notebook.utils import url_path_join
import requests
scheme = requests.utils.urlparse(window_loc).scheme
netloc = requests.utils.urlparse(window_loc).netloc
base_url = requests.utils.urlunparse((scheme,netloc, '', '', '', ''))
url = url_path_join(base_url, 'nbconvert', 'html', notebook_base, notebook_path)
r = requests.request('GET', url, params={'download':True})

if r.status_code == 200:
    with open(filename, 'wb') as f:
        for chunk in r.iter_content(1024):
            f.write(chunk)

they work okay when I execute one by one, but when I do 'run-all', it seems like the javascript ran async, so the next cell try to execute before it finishes saving and collecting the variables.

Any thoughts?

Cheers,
SL

The code the Javascript is sending to the kernel will certainly be out of order. You might try defining a function to do what you want in the kernel, and then sending code from the JS to call it.

Thanks Thomas. Would you have any pointers/links on how this can be done? Don't have a whole lot of js background. Cheers, SL

I meant something much like you're already doing, except in the Python code, do:

def export_html(notebook_path):
   ...

Then in the JS:

Jupyter.notebook.kernel.execute("export_html('"+notebook_path+"')");

However, looking at what it is you're trying to do more broadly, you might be interested in using nbparameterise:
https://github.com/takluyver/nbparameterise

Have a go with both the demos in the examples directory. After installing nbparameterise (pip install nbparameterise), run:

python webapp.py "Stock Display.ipynb"

python batch.py

The idea of nbparameterise is to change some parameters at the start of a notebook, then execute that notebook, updating the outputs. The resulting notebook can easily be saved or fed into nbconvert to turn it into HTML (for instance). And it doesn't need a browser to run.

Best wishes,

Thomas

Thanks Thomas.

I'll give nbparameterise a try.

I was able to make that function work, but only if it is on the last cell. If there are more cells after that, when I do 'run-all', it doesn't work properly. Still investigating why... something to do with the order of execution maybe.
