Sourcing an R script for an entire Quarto project

[arnaudgallou]

Description

I'd like to import/source an R script that contains helper functions for an entire Quarto project. Sourcing a script in a code chunk at the top level of index.qmd doesn't work for complex project such as books that requires sourcing a particular script in every .qmd file. See here for dummy project that will fail on rendering with the following error:

Quitting from lines 4-5 [unnamed-chunk-1] (intro.qmd)
Error in `bar()`:
! could not find function "bar"

Tested on macOS 13.6.7 and Quarto v. 1.5.56.

Is there a way to import a script for an entire project? I was hoping for something similar to pre-render that will run during the rendering process but that doesn't seem to exist.

No, you need to load it in every document.
Note that to avoid duplicating the code, you can put the code cell in a Quarto document and use the include shortcode in every document.
Each Quarto documents are computed independently.

This has already been discussed:
