I am not sure if this is actually intended behavior. When I replace a variable using the .code class, this causes additional backticks around both the output of the variable and the rest of the string and also inserts blank spaces.
I hope this example makes it more clear
l <- c("cli", "glue")
d <- deparse(l)
s <- paste0("install.packages(", d, ")")
# Replacement of `d` causes additional backticks
cli::cli_alert_info("To install, run {.code install.packages({d})}")
#> ℹ To install, run `` install.packages(`c("cli", "glue")`) ``
# No additional backticks
cli::cli_alert_info("To install, run {.code {s}}")
#> ℹ To install, run `install.packages(c("cli", "glue"))`Created on 2022-02-16 by the reprex package (v2.0.1)
