well I see dancer, catalyst, mojolicious, memcached, mogilesFS, perlbal, plack, starman, continuity, perl 5.16.3 and s megashitload of stuff on metacpan so I think perl is far from dead
"just like java, but on time and under budget"

I've had to do this. I had multiple log files being simultaneously
processed by log processors and aggregators for real-time monitoring.
(Each log processor was reading simultaneously from multiple files.)
The individual files got into the gigabytes and were frequently
rotated.
This worked pretty well, keeping up with significant amounts of traffic,
and never thrashing or ballooning memory usage. Perl 5.12.

Subject: printf question

Hopefully a simple question...
Given this printf that specifies some fixed length left justified columns:
printf "%-30s, %-30s, %-30s\n", $a, $b, $c;
How can I make the hardcoded number 30 use a variable, say $len instead?
This does not work:
printf "%-$lens, %-$lens, %-lens\n", $a, $b, $c;
I'm guessing because perl would have trouble knowing that the s at the end is not part of the
variable? Thanks.

Yes.
Either:
printf "%-${len}s, %-${len}s, %-${len}s\n", $a, $b, $c;
Or (more C-like):
printf "%-*s, %-*s, %-*s\n", $len, $a, $len, $b, $len, $c;

$format = "%-${len}s, %-${len}s, %-${len}s\n";
printf $format, $a, $b, $c;

Thanks much. I guess with Perl, its probably going to be adding either {}, [] or ().

I like the idea of putting $format in its own variable for readability and for use in
multiple printf statements. Thanks.
