Appender::Screen(3pm) User Contributed Perl Documentation Appender::Screen(3pm)
NAME
Log::Log4perl::Appender::Screen - Log to STDOUT/STDERR
SYNOPSIS
use Log::Log4perl::Appender::Screen;
my $app = Log::Log4perl::Appender::Screen->new(
stderr => 0,
utf8 => 1,
);
$file->log(message => "Log me
");
DESCRIPTION
This is a simple appender for writing to STDOUT or STDERR.
The constructor "new()" take an optional parameter "stderr", if set to a true value, the appender will log to STDERR. The default setting
for "stderr" is 1, so messages will be logged to STDERR by default.
If "stderr" is set to a false value, it will log to STDOUT (or, more accurately, whichever file handle is selected via "select()", STDOUT
by default).
Design and implementation of this module has been greatly inspired by Dave Rolsky's "Log::Dispatch" appender framework.
To enable printing wide utf8 characters, set the utf8 option to a true value:
my $app = Log::Log4perl::Appender::Screen->new(
stderr => 1,
utf8 => 1,
);
This will issue the necessary binmode command to the selected output channel (stderr/stdout).
