`{% filter solution %}` for Jupyter notebooks

[frenzymadness]

It'd be nice to have a possibility to hide solutions by {% filter solution %} also in Jupyter notebooks.

Maybe it would be easier to hide cells based on cell metadata. Would that work for you as well?

Yes, sure, whatever is easier to implement. I just don't know how does the machinery translating notebook to HTML works here. It would be nice if it would look the same as in MD/HTML and also with "uncover the solution" functionality.

This is the way we render Notebooks:

I dive deeper a little bit and now I understand how I can adjust nbconvert templates. But what I don't know yet is how I can combine it all together. It seems that adding the right class to some div element is not enough because the solution filter is much more complicated.

I can imagine that a simple modification of nbconvert template would add a {% filter solution %} around a cell content based on a cell metadata/tags. But then, the resulting HTML would have to be processed once more with Jinja.

Is there a simple way how to process a result of nbconvert NaucseHTMLExporter with Jinja? nbconvert uses Jinja internally so it might be possible to just register a template filter and let nbconvert to handle it.

There are three divs, see https://github.com/pyvec/naucse_render/blob/master/naucse_render/templates.py#L48

A quick temporary solution would be to avoid putting stuff in ctx['$solutions'], and omitting the link to solution_url. The downside is that you then need Javascript to see the solution.
