从仪表板小部件记录错误

Question

I recently took over maintenance of a widget for OSX Dashboard. A user is complaining about a bug which I've been unable to reproduce. I've been unable to find any error logs for Dashboard Widgets, although Dashcode displays an informative 'Run Log' containing both exceptions and javascript calls to alert(). Is there any way I could send the user a version which would log such information to a file to give me some idea of where the bug lies?

一种可能是在整个代码中调用如下代码：

widget.system("echo `date` 'My custom log line' >> /tmp/mydashboardwidget.log");
