Log::Dispatch::Screen(3pm) User Contributed Perl Documentation Log::Dispatch::Screen(3pm)
NAME
Log::Dispatch::Screen - Object for logging to the screen
SYNOPSIS
use Log::Dispatch::Screen;
my $screen = Log::Dispatch::Screen->new( name => 'screen',
min_level => 'debug',
stderr => 1 );
$screen->log( level => 'alert', message => "I'm searching the city for sci-fi wasabi\n" );
DESCRIPTION
This module provides an object for logging to the screen (really STDOUT or STDERR).
METHODS
* new(%p)
This method takes a hash of parameters. The following options are valid:
* name ($)
The name of the object (not the filename!). Required.
* min_level ($)
The minimum logging level this object will accept. See the Log::Dispatch doc-
umentation on Log Levels for more information. Required.
* max_level ($)
The maximum logging level this obejct will accept. See the Log::Dispatch doc-
umentation on Log Levels for more information. This is not required. By
default the maximum is the highest possible level (which means functionally
that the object has no maximum).
* stderr (0 or 1)
Indicates whether or not logging information should go to STDERR. If false,
logging information is printed to STDOUT instead. This defaults to true.
* callbacks( \& or [ \&, \&, ... ] )
This parameter may be a single subroutine reference or an array reference of
subroutine references. These callbacks will be called in the order they are
given and passed a hash containing the following keys:
( message => $log_message, level => $log_level )
The callbacks are expected to modify the message and then return a single
scalar containing that modified message. These callbacks will be called when
either the "log" or "log_to" methods are called and will only be applied to a
given message once.
* log_message( message => $ )
Sends a message to the appropriate output. Generally this shouldn't be called
directly but should be called through the "log()" method (in Log::Dispatch::Output).
