CapturedOutputMsg class

Message sent when a print() or stderr write is intercepted by the output-capture system.

When ProgramOptions.captureOutput is enabled, calls to print() inside the program zone are intercepted and dispatched as CapturedOutputMsg instead of being written to the terminal (which would corrupt the TUI).

Models can collect these messages to display in a debug panel, log viewer, or simply ignore them.

Example

@override
(Model, Cmd?) update(Msg msg) {
  return switch (msg) {
    CapturedOutputMsg(:final line, :final source) => (
      copyWith(logs: [...logs, '[$source] $line']),
      null,
    ),
    _ => (this, null),
  };
}
