#error(message, io: $stdout) ⇒ Object

io is for the commands whose stdout is data rather than chatter: odysseus logs web1 > app.log captures a log stream, and a notice about which container the logs came from does not belong in it. A default rather than a second set of methods, so every other caller keeps writing to stdout exactly as before.

# File 'lib/odysseus/cli/ui.rb', line 303

def error(message, io: $stdout)
  io.puts "  #{RED}#{RESET} #{message}"
end

#header(title, io: $stdout) ⇒ Object

--- Header ---

These three take io for the same reason error/warn/step below do: the interactive sessions print a header describing a terminal whose own output is stdout, so the description has to go somewhere else. The default keeps every other caller writing exactly where it did.
