Maybe I am being silly, but I struggle to write a condition that checks whether blogdown::build_site() was successful (to then decide whether to deploy). The function always returns NULL, and Hugo errors are not raised as R errors (or warnings).

Could the function possibly return TRUE/FALSE (invisibly) depending on whether the hugo build succeeded? Or is there already a solution that I am overlooking? (So far, I tried capture.output() but that also returns nothing.)
