Log::Dispatch::Screen - Object for logging to the screen
use Log::Dispatch::Screen; my $screen = Log::Dispatch::Screen->new( name => 'screen', min_level => 'debug', stderr => 1 ); $screen->log( level => 'alert', message => "I'm searching the city for sci-fi wasabi\n" );
This module provides an object for logging to the screen (really STDOUT or STDERR).
new(%PARAMS)
This method takes a hash of parameters. The following options are valid:
-- name ($)
The name of the object (not the filename!). Required.
-- min_level ($)
The minimum logging level this object will accept. See the Log::Dispatch documentation for more information. Required.
-- max_level ($)
The maximum logging level this obejct will accept. See the Log::Dispatch documentation 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
log_to
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).
