Code that has been highlighted is not displayed

[1kastner]

I used nbsphinx to create some highlighted code. The first block with the import statements looks fine, afterwards the code is not visible anymore, see here:

By the way, I am using Adobe to read the PDF.

Maybe some of the warnings are a reason for that?

The HTML page is in _build\simplepdf.

Do I need to manually install those fonts? And why does it try to open C:\\...\\docs\\_build\\simplepdf\\_static\\styles\\main.css? No such file exists. Mine is called custom.css as indicated in my conf.py. Is that bad in your case? And I have no idea where all these anchors come from. That is nothing I have created manually. However, I use some extensions that might have caused that.

[Sachin-Suresh]

I don't use any extensions. I tried with the new Sphinx installation and I still get these font warnings. Let me know if you find a workaround @1kastner

[1kastner]

@Sachin-Suresh I have not found any workaround.

[danwos]

The fonts warnings are just warnings, and I'm not sure if we can fix them easily, as you normally set multiple fonts in CSS, in the case some of them are not installed or available on the used operating system.
This would also be more the problem of the used weasyprint lib. (Or we can configure it to suppress such messages).

For the nbsphinx-problem, do you have some example code for me?
Would help me to reproduce the problem the right way.
I would also add it to our DEMO-PDF, so that we can have an eye on it for future releases.

[1kastner]

Thanks for the explanation. Well, a small show-off of nbsphinx you can find at https://github.com/spatialaudio/nbsphinx/blob/master/doc/code-cells.ipynb. If that whole notebook takes too much space, the Jupyter Notebook could also be reduced to the following cells:

The short explanation of how to set it up can be found at https://nbsphinx.readthedocs.io/en/0.8.9/ and the prerequisites at https://nbsphinx.readthedocs.io/en/0.8.9/installation.html#nbsphinx-Prerequisites.
