🚀 Quick Reference

Use Case	Command	Description
📥 Log to STDERR (default)	Log::Log4perl::Appender::Screen->new()	Creates appender writing to STDERR
📤 Log to STDOUT	Log::Log4perl::Appender::Screen->new(stderr => 0)	Switch output to STDOUT
🌐 Enable UTF-8 output	Log::Log4perl::Appender::Screen->new(stderr => 1, utf8 => 1)	Allows wide UTF-8 characters on the selected channel
📝 Log a message	$app->log(message => "Log me\n")	Send a log line to the appender

📝 SYNOPSIS

use Log::Log4perl::Appender::Screen;

my $app = Log::Log4perl::Appender::Screen->new(
  stderr    => 0,
  utf8      => 1,
);

$file->log(message => "Log me\n");

🧵 DESCRIPTION

This is a simple appender for writing to STDOUT or STDERR.

The constructor new() takes 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 UTF-8 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).
