NAME¶
MooseX::LazyLogDispatch - A Logging Role for Moose
VERSION¶
This document describes MooseX::LazyLogDispatch version 0.01
SYNOPSIS¶
package MyApp;
use Moose;
with MooseX::LazyLogDispatch;
# or alternately, use this role instead to give your
# class the logger methods "debug", "warning", etc...
# with MooseX::LazyLogDispatch::Levels;
# This part optional
# without it you get some default logging to the screen
has log_dispatch_conf => (
is => 'ro',
isa => 'Log::Dispatch::Configurator',
lazy => 1,
required => 1,
default => sub {
my $self = shift;
My::Configurator->new( # <- you write this class!
file => $self->log_file,
debug => $self->debug,
);
},
);
# Here's another variant, using a Log::Dispatch::Configurator-style
# hashref to configure things without an explicit subclass
has log_dispatch_conf => (
is => 'ro',
isa => 'HashRef',
lazy => 1,
required => 1,
default => sub {
my $self = shift;
return $self->debug
? {
class => 'Log::Dispatch::Screen',
min_level => 'debug',
stderr => 1,
format => '[%p] %m at %F line %L%n',
}
: {
class => 'Log::Dispatch::Syslog',
min_level => 'info',
facility => 'daemon',
ident => $self->daemon_name,
format => '[%p] %m',
};
},
);
sub foo {
my ($self) = @_;
$self->logger->debug("started foo");
....
$self->logger->debug('ending foo');
}
DESCRIPTION¶
Log::Dispatch role for use with your Moose classes.
INTERFACE¶
logger¶
This method is provided by this role, and it is an Log::Dispatch instance, which you can call level-names on, as in the debug examples in the synopsis.
If you want the level-names as direct methods in your class, you should use the MooseX::LazyLogDispatch::Levels role instead.
log_dispatch_config¶
This is an optional attribute you can give to your class. If you define it as a hashref value, that will be interpreted in the style of the configuration hashrefs documented in Log::Dispatch::Config documents when they show examples of using Log::Dispatch::Configurator for pluggable configuration.
You can also gain greater flexibility by defining your own complete Log::Dispatch::Configurator subclass and having your "log_dispatch_config" attribute be an instance of this class.
By lazy-loading either one ("lazy =" 1>), you can have the configuration determined at runtime. This is nice if you want to change your log format and/or destination at runtime based on things like MooseX::Getopt / MooseX::Daemonize parameters.
If you don't provide this attribute, we'll default to sending everything to the screen in a reasonable debugging format.
