Asynchronous alert

[* Tong *]

Hi,

I'm trying to write an alert detection script.

Generally, the script loops to detect if the alert criteria is met,
and if so, alert the user. Somewhat like this:

for(;{
my $alerted;
my $flag=detect_flag
if($flag){
alert_user unless $alerted;
$alerted=1
}
}

The 'alert_user' can be as simple as a pop up window via Xdialog. Once the
alert goes off, it might take some time to resolve, but I don't want to
alert user again and again, hence the '$alerted' var. The problem is that
I need a way to clear the '$alerted' var. I think, to make it simple, the
best time is when the user confirm the alert pop up window.

Now, what's the easiest way to do it? The reason I wanted to use Xdialog is
because it's extreme easy to code, but I can't think of a way to clear the
'$alerted' var.

please help

thanks a lot

my $alerted;
for(;{
my $flag=detect_flag
if($flag){
alert_user unless $alerted;
$alerted=1
}
}

Most probably, making $alerted a package variable will do it. You might
also be able to solve the problem by putting "my $alerted" above the for
loop.

thanks for the suggestion. please see above. Please note that, what I need
is the simplest solution.

Since the program you posted is not complete, it's hard to comment
further.

IMHO, as a *general purpose* *high-level* code snip, it is complete. What
only lacks is the way/mechanism to reset $alerted asynchronous, which I
don't know and is asking -- how to reset it determines how the alert_user()
is coded, and there is no need to dive into the detect_flag() at all.

thanks

my $alerted;

Doh! How did I miss that?

for(;{
my $flag=detect_flag
if($flag){
alert_user unless $alerted;
$alerted=1
}
}

Under what conditions do you want to clear the $alerted flag?

I think, to make it simple, the best time is when the user confirm the
alert pop up window -- i.e., user click, pop up gone, $alerted cleared.

how is that?

You need to post an actual (short) program. The solution is not simply
conceptual.
