Log::Log4perl::Config::PropertyConfigurator(3) reads properties file


# This class is used internally by Log::Log4perl
use Log::Log4perl::Config::PropertyConfigurator;
my $conf = Log::Log4perl::Config::PropertyConfigurator->new();
$conf->parse(); # will die() on error
my $value = $conf->value("log4perl.appender.LOGFILE.filename");

if(defined $value) {
printf("The appender's file name is $value\n");
} else {
printf("The appender's file name is not defined.\n");


Initializes log4perl from a properties file, stuff like

    log4j.category.a.b.c.d = WARN, A1
    log4j.category.a.b = INFO, A1

It also understands variable substitution, the following configuration is equivalent to the previous one:

    settings = WARN, A1
    log4j.category.a.b.c.d = ${settings}
    log4j.category.a.b = INFO, A1
