Description

Im trying to use variables in _quarto.yml it looks like variables in an href do no expand? Am I using the wrong syntax?

my _variables.yml file ------------

bril: bril_expand

my _quarto.yml file

project:
type: website
title: "{{< var bril >}}"

website:
sidebar:
contents:
- text: "Bril Documentation"
href: "{{< var bril >}}"

my index.qmd file

title: "junk"

index
Version {{< var bril >}} is a minor upgrade.

I'm use the bril variable in 3 places
in index.qmd works
in _quarto.yml title works
in _quarto.yml href - does not expand

sorry for the crap format - This is my first post so I don't know how to put in a repro case

Could you properly format your post using code blocks for code and terminal outputs? Thanks.
If your code contains code blocks, you need to enclose it using more backticks, i.e., usually four ````.

Note that the formatting guidelines were provided when you opened the discussion.

You can share a self-contained "working" (reproducible) Quarto document using the following syntax, i.e., using more backticks than you have in your document (usually four ````).
See https://quarto.org/bug-reports.html#small-is-beautiful-aim-for-a-single-document-with-10-lines.

If you have multiple files (and if it is absolutely required to have multiple files), please share as a Git repository.

R	Python
````qmd --- title: "Reproducible Quarto Document" format: html engine: knitr --- This is a reproducible Quarto document. ```{r} x <- c(1, 2, 3, 4, 5) y <- c(1, 4, 9, 16, 25) plot(x, y) ```  The end. ````	````qmd --- title: "Reproducible Quarto Document" format: html engine: jupyter --- This is a reproducible Quarto document. ```{python} import matplotlib.pyplot as plt x = [1, 2, 3, 4, 5] y = [1, 4, 9, 16, 25] plt.plot(x, y) plt.show() ```  The end. ````

Additionally and if not already given, please share the output of quarto check within a code blocks (i.e., using three backticks ```txt), see https://quarto.org/bug-reports.html#check.
