prosodyctl shell: Move non-error result lines back to stdout, suppress with --quiet We're figuring out how to keep usability and support machine-readability too. We moved the status line (repl-result) to stderr so that when parsing something like a table, it didn't get in the way. However sometimes the status line is the thing we want to parse (e.g. invite creation). Parsing stderr loses one of the purposes of stderr - to have an error-only channel to emit stuff out of band (such as error messages). So the new approach is: - Status line on stdout, unless it's an error - If you're parsing the output ("content") of the command, pass --quiet to suppress the status line.
