Color and text disappear when using custom console transport format. #397

Closed NotLazy closed 5 months ago

NotLazy commented 5 months ago

When I use the default console transport format, I get color and my logged messages:

But when I use a custom console transport format:

Here's my custom format: %c{h}:{i}:{s}.{ms}%c {sender} › {text} sender is defined using log.variables.sender = currentContext; before calling log.silly() or log.info() (the two levels shown in screenshots)

  log.hooks.push((msg, _, transportName) => {
    if (transportName === 'console') {
      msg.data.unshift('color: blue', 'color: unset');
    }

    return msg;
  });

    if (transportName === 'console') {
      msg.data.unshift('color: blue', 'color: unset');
    }

    return msg;
  });

This works for console but causes file and remote handlers to have this text in them, even though specifically locking it with transportName

in the log file:

Ok, try clonning msg object instead

log.hooks.push((msg, _, transportName) => {
  if (transportName === 'console') {
    return {
      ...msg,
      data: ['color: blue', 'color: unset', ...msg.data],
    }
  }

  return msg;
});

This worked. I had tried only cloning msg or only cloning msg.data but, cloning both was the answer here. Thanks!
