Is it possible to embed a Jupyter notebook cell in a second notebook rendered in revealjs?

[lebedov]

Is it possible to embed a cell in one Jupyter notebook within another notebook such that rendering the latter as a revealjs presentation will cause the former to be included? I tried creating a sub_notebook.ipynb file with a single code cell containing

#| label: fig_1
import matplotlib.pyplot as plt
import numpy as np
plt.scatter(np.random.rand(10), np.random.rand(10));

and a main_notebook.ipynb file with a raw cell containing

---
title: Main Notebook
format: revealjs
---

followed by a second Markdown cell containing

{{< embed sub_notebook.ipynb#fig_1 >}}

I then tried rendering main_notebook.ipynb into HTML after generating the plot in sub_notebook.ipynb and saving that notebook; however, the cell from sub_notebook.ipynb did not appear in the rendering of the latter.

The context for the above is trying to pull in select results from several Jupyter notebooks into one notebook used to present the results. Yes, I know one can create a raw Markdown file that pulls in the results from several notebooks, but it would be useful to do the same with a notebook so that the resulting presentation could also use content local to that notebook.
I'm using quarto 1.3.450 on MacOS 13.5.

I just took this for a test run on Quarto 1.4.302 (pre-release) https://quarto.org/docs/download/prerelease and everything appeared to be working. We have been making a number of improvements to embed in Quarto 1.4, so it is definitely possible that this changed between Quarto 1.3 and 1.4.

If you still see problems - it would be useful to have a sample repo / notebooks to try. I tried to reproduce what you have above a as closely as possible, but sometimes there is a subtle difference that results in the issue not reproducing.

Confirmed - it does indeed work with Quarto 1.4.302, although it seems that no link to the source notebook is added. @dragonstyle Is any link being generated on your end?

[dragonstyle]

No - we currently don't generate notebook previews for RevealJs (or books).

No matter - the core embedding functionality is sufficient for my purposes. Thanks for the quick response!
