Bug

In emacs/ess, the output is colored (i.e., red in errors) but the ansi color sequence is not reset, so the emacs/ess prompt stays colored.

The cli::style_reset object (printed, not when called as a function) remedies the color problem.

Any chance you can augment whatever cli:: stuff is being done so that it resets the terminal? I don't know if RStudio IDE just hard-codes it all the time, but emacs/ess has this issue.

(A clear workaround is to use Sys.setenv(NO_COLOR="!") per https://cli.r-lib.org/reference/faq.html, though the defeats some benefit of colors :-)

I will look into cli::style_reset() as a possible cleanup step.

f9de627 adds message(cli::style_reset(), appendLF = FALSE). Please let me know if this does not fix the issue.
