Only the first cell is visible with certain files

[improbable-22]

I just found this program, and am having difficulty with certain notebooks. The ones I have saved myself work fine, but those produced by the Julia package Literate.jl don't seem to work.

This package turns files like example.jl into notebooks like example.ipynb. I attach an example of what I see. Only the first cell is shown by nbviewer-app, while nteract (the window behind) shows more.

I don't know which end has the problem here -- it only happens for me with this viewer and such files together. Files created directly in Jupyter work fine. And Jupyter itself works fine with these files.

Interesting... If you open the same file in Jupyter and then save it, it will correctly show also in nbviewer-app. This is actually a problem with the JSON produced from Literate.jl.. I could trace the problem to the first output cell, where nbviewer.js expects an array, but only a string literal is found (here, for example).

Should be an easy fix. I'll look into it.

That I did not think to try, thanks for taking a look.

Is this something Literate.jl ought to change, to conform to standard, or more of a grey area?

Looking through the notebook file format docs, the behavior of Literate.jl is totally fine:

If you intend to work with notebook files directly, you must allow multi-line string fields to be either a string or list of strings.

So this should be fixed in nbviewer.js, which is used by nbviewer-app to render the notebooks.

OK, I've opened an issue on nbviewer.js. Thanks again for digging into this (and for the app).

Thanks for reporting this, I think I've fixed it (and one other related thing), see #28.

Thanks for fixing this, @kokes. I'll merge an updated version of nbviewer.js when #5 is addressed. I'll file a PR if you don't beat me to it 😉
