Thanks for the quick reply. I've thought of doing this. The problem is I
don't think it's efficient since I have to open and return a template every
time an exception occurred.
This means, instead of two simple lines
warn "blablabla!\n";
return;
I will have
my $template = HTML::Template->new( filename => "error_screen" );
$template->param(
VERSION => $VERSION,
RELEASE => $RELEASE,
RUN_MODE => 'this_run_mode',
ERROR_MSG => 'Something weird occurred!\n"
);
return $template->output;
I will have three lines of code!
I was looking for something like a call to a specialized routine whic�h got
the error message passed in. Like the "AUTOLOAD" run-mode. Unfortunately, I
don't know how to pass an error message to the method which is called by
"AUTOLOAD" and don't even know how to cause this method to be called.
Loads'f thanks for your feedback. Your answer is probably the easiest way.
