How do I globally turn on echo=true when generating jupyter output?

Description

I have a bunch of revealjs slides. Occasionally I have blocks like

```{python}
#| echo: false
a = 2
```

in cases where I don't want the output to show in the slides. But when I do quarto render myfile.qmd --to ipynb I want all of the code blocks to display, or else the jupyter notebook wouldn't be functional. How do I force it to echo all code in that case without manually search/replace all of my files?

I think the easiest way to do it is the other way around. I believe we have echo: false by default in presentation formats, so this should do what you need to.

In case the defaults don't work for you, then I think project profiles are what you're looking for: https://quarto.org/docs/projects/profiles.html

Indeed, echo: false is the default for revealjs format.

Note that you can enable echo: true from the command line.

quarto render index.qmd --metadata echo:true

That did it. Left off the echo: false for anything I don't want echo'd in revealjs but want echoed in ipynb, and it had the intended behavior.
