Theme customizer panel not working

[Teebusch]

Describe the problem

Changing a variable in the bs_themer theme customizer panel has no effect. A warning is displayed instead.

library(bslib)

bs_theme_preview(theme = bs_theme(), with_themer = TRUE)

# Then, in the app, change any variable using the theme customizer.

# > Warning: bs_themer() encountered malformed input; ignoring

# The theme preview does not change

(changing the overall theme with the dropdown and the dark mode toggle do work)

Fixed by #1112, which isn't yet on CRAN. In the mean time you can use the development version of bslib by installing from GitHub or r-universe.dev.

# From GitHub
pak::pak("rstudio/bslib")

# From r-universe
install.packages("bslib", repos = c("https://rstudio.r-universe.dev", "https://cloud.r-project.org"))
