Often status messages are associated with processes. E.g. the app starts
downloading a large file, so it sets the status bar accordingly. Once the
download is done (or failed), the app typically updates the status bar
again. cli automates much of this, via the msg_done
, msg_failed
, and
.auto_result
arguments. See examples below.
cli_process_start for a higher level interface to the startus bar, that adds automatic styling.
