NAME

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

SYNOPSIS

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

           my $app = Log::Log4perl::Appender::Screen->new(
             autoflush => 1,
             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 false value, it will log all levels to STDOUT (or, more accurately, whichever file handle
           is selected via "select()", STDOUT by default).

       •   If  set  to a hash, then any "log4p_level" with a truthy value will dynamically use STDERR, or STDOUT
           otherwise.

       •   Otherwise, if a true value (the default setting is 1), messages will be logged to STDERR.

           # All messages/levels to STDERR
           my $app = Log::Log4perl::Appender::Screen->new(
               stderr  => 1,
           );

           # Only ERROR and FATAL to STDERR (case-sensitive)
           my $app = Log::Log4perl::Appender::Screen->new(
               stderr  => { ERROR => 1, FATAL => 1},
           );

       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).

       To enable autoflush, set the "autoflush" option to a true value:

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

       This will issue the necessary autoflush command to the selected output channel (stderr/stdout).

       This is required in containers, especially when the log volume is low, to not buffer the log messages and
       cause a significant delay.
