Change code background color in PDF document?

[maxdrohde]

After downloading the new version of Quarto, it seems that the default background color for code in PDF documents has changed from blue to white. See below for an example.

Does anyone know how to manually set the default background color for code? I tried looking on this page but couldn't find any options: https://quarto.org/docs/reference/formats/pdf.html

Great question (it was a little challenging to find in our docs, maybe something we can improve). More is here:

https://quarto.org/docs/authoring/article-layout.html#code-blocks

if you set code-block-border-left: false, it will go back to the background color treatment...

For example:

format:
  pdf:
    code-block-border-left: false

@dkStevensNZed Could you share a fully (and small) reproducible example? yours is not in addition to not be formatted corrected inside a markdown code blocks. Thank you.

Note that this discussion was opened/closed before Quarto was officially release.
Since then there were a lot of internal changes including a a major upgrade of Pandoc the underlying tool used by Quarto.
So, the solution might need some tweaks.

Sorry about that. Here's a simple example. When I render to html, the code box is shaded. When I render to pdf, there's no shading. For unknown reasons, the indentation in the YAML is lost when the message is posted.

New info: If I remove the format/pdf lines

toc: true
toc-depth: 3
lof: true
lot: true
listings: true

the shading is working in pdf. With these lines, there is no shading.

Here's a code box

d <- 1
print(d)

Update. It appears that the

listings: true
is causing the problem. Without that line, the shading appears, even with the toc/lof/lot included

@dkStevensNZed Could you edit and format properly your posts? They are currently unusable. If your code include code blocks, you need to use more backticks on the enclosing code blocks.

The attached file contains TestCodeBox.qmd (quarto document) that compiles but does not shade the code boxes.
