HTML Export with Embedded Images in Base64

[gabyx]

Would it be hard to write an export function which exports the HTML but embeds every image in Base64 encoding? I would contribute that, but need some starting points

Can anybody give me some starting point on what to extent, it might be easier :-) Is there already such an exportet available somewhere? Ist it a template I have to write or rather a preprocessor ??

Take a look at the exporters in ipython-contrib: http://jupyter-contrib-nbextensions.readthedocs.io/en/latest/exporting.html

Thanks, the question arose, when nbconvert.exporters.export_locater from the browser) will no more be used in jupyter (deprecated, but used when exporting with javascript Jupyter.menubar._nbconvert('html_embed', true);)

Only then my Embedded HTML export button works in : https://github.com/gabyx/jupyter_contrib_nbextensions/blob/master/src/jupyter_contrib_nbextensions/nbextensions/export_embedded/main.js -> see htmlembedded string which is enabled by my fork of nbconvert where I hardcoded the exporter in to the list (hopefully no more needed in the future) ;-)

I think your issue is that you may have not declared an exporter with an entrypoint that allows it to be found. If you just make package your exporter with an entrypoint you should have no difficulty using the standard nbconvert machinery. This use case is basically the reason for which we introduced exporter entrypoints.

exporter_locator is not used in modern versions of the notebook's backend nbconvert handlers, but get_exporter is and it is used via that JavaScript call which hits the nbconvert handler.

I have defined my exporter with an entry_point, since I forked from jupyter_contrib_extensions I added it in the setup and on the cmd line it works perfectly, but in the notebook it does not, jupyter 4.3.0, probably an issue for the notebook?
