VERSION
version 0.01
SYNOPSIS
use Log::Dispatch::Channels;
my $logger = Log::Dispatch::Channels->new;
$logger->add_channel('foo');
my $timestamper = sub { my %p = @_; return time . $p{message}; };
$logger->add_channel('bar', callbacks => $timestamper);
$logger->add(Log::Dispatch::File->new(channels => 'foo',
name => 'foo',
min_level => 'debug',
filename => 'foo.log'));
$logger->add(Log::Dispatch::Null->new(channels => 'bar',
name => 'bar',
min_level => 'debug'));
$logger->add(Log::Dispatch::File->new(channels => [qw/foo bar/],
name => 'errors',
min_level => 'error',
filename => 'error.log'));
$logger->log(channels => 'foo', level => 'debug',
message => 'For foo');
$logger->log(channels => 'bar', level => 'error',
message => 'For bar and errors');
DESCRIPTION
This module manages a set of Log::Dispatch objects, treating them as separate message channels to which messages can be logged. These objects can share Log::Dispatch::Output objects, to allow for logging to multiple places simultaneously and automatically.
METHODS
new()
Returns a new Log::Dispatch::Channels object.
add_channel($NAME, @ARGS)
Adds a new message channel named $NAME. This channel is actually a Log::Dispatch object, and @ARGS is forwarded on to the Log::Dispatch constructor.
remove_channel($NAME)
Removes the channel named $NAME and returns it.
add($OUTPUT[, channels => $NAMES])
Adds $OUTPUT (which is a Log::Dispatch::Output object), and also adds it to each channel named in $NAMES. $NAMES can be a string specifying a single channel, an arrayref of strings specifying multiple channels, or left out to add the output to all channels (this applies for each function taking a 'channels' argument).
remove($NAME)
Removes the output named $NAME from the object and from each of the channels, and then returns it.
log([channels => $NAMES,] %ARGS)
Forwards %ARGS on to the log method of each channel listed in $NAMES.
log_and_die([channels => $NAMES,] %ARGS)
Forwards %ARGS on to the log_and_die method of each channel listed in $NAMES.
log_and_croak([channels => $NAMES,] %ARGS)
Forwards %ARGS on to the log_and_croak method of each channel listed in $NAMES.
log_to(name => $NAME, %ARGS)
Forwards %ARGS on to the log method of the output named $NAME.
would_log($LEVEL[, channels => $NAMES])
Returns true if any channel named in $NAMES would log a message of level $LEVEL.
output($NAME)
Returns the Log::Dispatch::Output object named $NAME.
channel($NAME)
Returns the Log::Dispatch object named $NAME.
