Here's a nice new Log4perl extension that just made it to CPAN:

Subject: Log4perl command line options
Date: Mon, 4 Aug 2008 16:27:27 -0400
I attended your talk at OSCON about Log4perl (which I enjoyed
immensely, thank you!),
and asked a question about command line options rather than config files.
I've thought about it a bit since then, and put together the attached
module. Everything
is still in flux. This isn't intended to replace the configuration
file interface (which
is infinitely more configurable), but rather to make an easy way to 1)
make use of
Log4perl even if you don't want to think about the config files (or
teach end users
how to write them), and 2) provide an easy command line way to override a couple
parts without continually editing/saving a new config file.
What do you think about the proposed module name:
Log::Log4perl::CommandLine
As implemented, I just call Getopt::Long to do all the command line
option parsing,
but I know you don't want to add dependencies on external modules for your core
Log4perl module. This could be released independently if that was a concern.
To illustrate, I took the simple "drink soda" script from one of your
tutorial articles
and changed it like this:
=================================
use Log::Log4perl qw(:easy);
use Log::Log4perl::CommandLine;
drink();
drink("Soda");
sub drink {
my($what) = @_;
my $logger = get_logger();
if(defined $what) {
$logger->info("Drinking ", $what);
} else {
$logger->error("No drink defined");
}
}
==================================
Now it is command line enabled, and you can do things like this:
% perl log.pl
2008/08/04 15:55:53 No drink defined
% perl log.pl -v (or --verbose)
2008/08/04 15:55:56 No drink defined
2008/08/04 15:55:56 Drinking Soda
% perl log.pl -q (or --quiet)
% perl log.pl --debug --logfile log.txt
2008/08/04 16:08:16 No drink defined
2008/08/04 16:08:16 Drinking Soda
% cat log.txt
2008/08/04 16:08:16 No drink defined
2008/08/04 16:08:16 Drinking Soda
% perl log.pl --trace My::Module
[...]
What do you think?
