Ok I've been at this all day, and I've discovered some nifty things.
It was pretty trivial to redirect output to an html textarea. The html
markup/styling gave me way more trouble than the managed code (I
really hate html.)
The big find though was the Application.Current.UnhandledException event.
def excepthook(sender, e):
sys.stdout = sys.stderr = DebugStream()
Application.Current.UnhandledException += excepthook
# start application
Which will print unhandled exceptions, even ones that occur in
But of course this prints a .NET traceback, which is pretty much
useless for IronPython. But surely there is some way to print a python
exception once I have this .NET exception object?
