Automatically save notebook as HMTL with... JavaScript?

[Mayeshh]

Hello,

I am very new to python, and I am currently using Jupyter notebooks to analyze microscopy data. I have looked into using `nbconvert` as a library, however, I have to run these particular notebooks manually (centering images, choose files through globing, etc.). For this reason, I don't want to implement `nbconvert` from the command line. 

My not-solution has been to use the Jupyter notebook GUI to save the output as HTML (required for record keeping) and update the name manually. This is problematic because I can easily forget to save the notebook or name it incorrectly. I am also trying to speed up my workflow, and I have identified this step as a bottleneck...

How can I automate this action within the notebook? Will it require JavaScript? If so, I lack any knowledge of JavaScript... Can anyone offer a solution to this use-case? Any advice is greatly appreciated!

I suspect what you want is a post-save hook that calls nbconvert. For example:

import io
from nbcovert import export, HTMLExporter

def script_post_save(model, os_path, contents_manager, **kwargs):
    """convert notebooks to HTML after save with nbconvert"""

    if model['type'] != 'notebook':
        return

    global _exporter

    if _exporter is None:
        _exporter = HTMLExporter(parent=contents_manager)

    base, ext = os.path.splitext(os_path)
    # your rename logic goes here
    html_fname = base + '.html'
    html, resources = _exporter.from_filename(os_path)

    with io.open(html_fname, 'w', encoding='utf-8') as f:
        f.write(html)

c.FileContentsManager.post_save_hook = script_post_save
