Log::Log4perl::Appender::Screen - Log to STDOUT/STDERR


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

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

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


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).
