Include generated image in ipynb with echo: false

[jlperla]

Description

When #| echo: false is put into a code cell, it seems to execute the code and then strip out the code ex-post. This isn't a problem with HTML/RevealJS, etc. output because you never need to rerun the notebooks.

However, if you also generate ipynb notebooks (with a ipynb: default in the format, etc.) then this behavior is not what you really want, because it leaves an empty code cell. If the user ever reruns the notebook then the output (e.g., generated image) disappears since the cell which genreated it is empty.

Is there a feature to make this possible and maybe convert the output to be a different sort of ipynb cell that doesn't get overwritten? Maybe even strip out the empty code cells in the transformation?

If you want to keep echo: true for only ipynb and echo: false for others, I think you can do something like

---
title: "specifying option per format"
format:
  html: default
  ipynb:
    execute: 
      echo: true
execute: 
  echo: false
---
```{python}
1 + 1
```

Options can be tweaked per format, as Quarto will matched any know options to put same in the right place. (execute being execution option)

Even this works

format:
  html: default
  ipynb:
    echo: true

but a bit less explicit

Thanks. Actually, what I want is for (a subset of cells) the code to be missing in the ipynb but the figure to remain (and not be overwritten if the student executes the notebook again. This is for an exam where I don't want them to see how I generated the figures.

I thought maybe using the echo: false and output: Asus might due it,but the html it generates shows directly in the notebook rather than being rendered. Is there a way to wrap that code cell with the raw output?

I am not completely sure to follow exactly the source you have, and the expected output you want.

echo: fenced is a way to get the raw block as in .qmd source, but shown asis in output. So not sure you want that.

I thought maybe using the echo: false and output: Asus

echo: false means no source and output: asis means that your cell output is to be considered as Raw markdown content.

I don't know if quarto as of today can do what you want. It seems like you want quarto to echo: false the cell, so that only output is considered, but you want to have also some empty cell shown. So maybe you need to do both and duplicate ?

# Exercise

```{python}
#| echo: true`
<empty cell>
```

# Solution

```{python}
#| echo: false
<plot here>
```

🤷‍♂️

Having an example could help

Thank you. After digging around I think that there was just an issue with the julia support for output: asis with figures.

See #12197 for a replication, I will close this issue as I think the answer is simply that the #| echo: false and #| output: asis is the intended feature to do exactly what I was looking for.
