Catalyst::Log(3) User Contributed Perl Documentation Catalyst::Log(3)NAMECatalyst::Log - Catalyst Log Class
SYNOPSIS
$log = $c->log;
$log->debug($message);
$log->info($message);
$log->warn($message);
$log->error($message);
$log->fatal($message);
if ( $log->is_debug ) {
# expensive debugging
}
See Catalyst.
DESCRIPTION
This module provides the default, simple logging functionality for
Catalyst. If you want something different set "$c->log" in your
application module, e.g.:
$c->log( MyLogger->new );
Your logging object is expected to provide the interface described
here. Good alternatives to consider are Log::Log4Perl and
Log::Dispatch.
If you want to be able to log arbitrary warnings, you can do something
along the lines of
$SIG{__WARN__} = sub { MyApp->log->warn(@_); };
however this is (a) global, (b) hairy and (c) may have unexpected side
effects. Don't say we didn't warn you.
LOG LEVELS
debug
$log->is_debug;
$log->debug($message);
info
$log->is_info;
$log->info($message);
warn
$log->is_warn;
$log->warn($message);
error
$log->is_error;
$log->error($message);
fatal
$log->is_fatal;
$log->fatal($message);
METHODS
new
Constructor. Defaults to enable all levels unless levels are provided
in arguments.
$log = Catalyst::Log->new;
$log = Catalyst::Log->new( 'warn', 'error' );
level
Contains a bitmask of the currently set log levels.
levels
Set log levels
$log->levels( 'warn', 'error', 'fatal' );
enable
Enable log levels
$log->enable( 'warn', 'error' );
disable
Disable log levels
$log->disable( 'warn', 'error' );
is_debug
is_error
is_fatal
is_info
is_warn
Is the log level active?
abort
Should Catalyst emit logs for this request? Will be reset at the end of
each request.
*NOTE* This method is not compatible with other log apis, so if you
plan to use Log4Perl or another logger, you should call it like this:
$c->log->abort(1) if $c->log->can('abort');
_send_to_log
$log->_send_to_log( @messages );
This protected method is what actually sends the log information to
STDERR. You may subclass this module and override this method to get
finer control over the log output.
