Welcome to the recipe of the week. Today, let's talk about stealth loggers:
What's the easiest way to use Log4perl?
If you just want to get all the comfort of logging, without much
overhead, use *Stealth Loggers*. If you use Log::Log4perl in ":easy"
mode like
use Log::Log4perl qw(:easy);
you'll have the following functions available in the current package:
DEBUG("message");
INFO("message");
WARN("message");
ERROR("message");
FATAL("message");
Just make sure that every package of your code where you're using
them in
pulls in "use Log::Log4perl qw(:easy)" first, then you're set.
These stealth loggers will be absolutely silent until you initialize
Log::Log4perl in your main program with either
# Define any Log4perl behaviour
Log::Log4perl->init("foo.conf");
(using a full-blown Log4perl config file) or the super-easy method
# Just log to STDERR
Log::Log4perl->easy_init($DEBUG);
or the parameter-style method with a complexity somewhat in between:
# Append to a log file
Log::Log4perl->easy_init( { level => $DEBUG,
file => ">>test.log" } );
For more info, please check out the "Stealth Loggers" section in the
main Log::Log4perl documentation page.
Have fun!
