Consider adding a standalone shell engine that doesn't rely on Knitr or Jupyter

[ndusek]

Quarto CLI seems to be very useful for creating basic Linux and Bash shell documentation. It would be nice if Quarto supported syntax highlighting and execution of shell code without the need for the full Knitr or Jupyter stacks.

What would it take to create a standalone execution engine just for the shell?

What about Windows user? 🤔
It seems a lot of work and not for all users, especially because some are using PowerShell, BASH, etc.
And where to stop, an engine for each programming language?

In my opinion, Quarto is not about building engines, but is about the publishing/editing/writing side.
This is why, they are using existing tools to perform the computations.

This being said, if you are aware of some existing tool such as Jupyter/knitr/etc., please do share to Quarto team.
You could also try to build what you want and ask Quarto how it could be used inside Quarto.

Final note, please note that knitr/R or Jupyter/Python are not installed nor provided by Quarto, they are external tools.

This is not exactly what you asked for, but the nice thing about jupyter is that there exist jupyter kernels for a lot of languages.

See this impressive list: https://github.com/jupyter/jupyter/wiki/Jupyter-kernels

In principle, they should all be usable for code execution with Quarto. And syntax highlighting is done by pandoc, anyway:

$ pandoc --list-highlight-languages | wc -l
148

A bash kernel is here: https://github.com/takluyver/bash_kernel

Same applies for both computing engines.
Here, he does not want any of the engines.
