SYNOPSIS
In MyApp.pm:
use Catalyst::Log::Log4perl;
# then we create a custom logger object for catalyst to use.
# If we don't supply any arguments to new, it will work almost
# like the default catalyst-logger.
__PACKAGE__->log(Catalyst::Log::Log4perl->new());
# But the real power of Log4perl lies in the configuration, so
# lets try that. example.conf is included in the distribution,
# alongside the README and Changes.
__PACKAGE__->log(Catalyst::Log::Log4perl->new('example.conf'));
And later...
$c->log->debug("This is using log4perl!");
DESCRIPTION
This module provides a Catalyst::Log implementation that uses Log::Log4perl as the underlying log mechanism. It provides all the methods listed in Catalyst::Log, with the exception of:
levels enable disable
These methods simply return 0 and do nothing, as similar functionality is already provided by Log::Log4perl.
These methods will all instantiate a logger with the component set to the package who called it. For example, if you were in the MyApp::C::Main package, the following:
package MyApp::C::Main; sub default : Private { my ( $self, $c ) = @_; my $logger = $c->log; $logger->debug("Woot!"); }
Would send a message to the Myapp.C.Main Log::Log4perl component.
See Log::Log4perl for more information on how to configure different logging mechanisms based on the component.
METHODS
- new($config, [%options])
-
This builds a new Catalyst::Log::Log4perl object. If you provide an argument
to new(), it will be passed directly to Log::Log4perl::init.
The second (optional) parameter is a hash with extra options. Currently three additional parameters are defined:
'autoflush' - Set it to a true value to disable abort(1) support. 'watch_delay' - Set it to a true value to use L<Log::Log4perl>'s init_and_watch 'override_cspecs' - EXPERIMENTAL Set it to a true value to locally override some parts of L<Log::Log4perl::Layout::PatternLayout>. See L<OVERRIDING CSPECS> below
Without any arguments, new() will initialize a root logger with a single appender, Log::Log4perl::Appender::Screen, configured to have an identical layout to the default Catalyst::Log object.
- _flush()
- Flushes the cache. Much like the way Catalyst::Log does it.
- abort($abort)
- Causes the current log-object to not log anything, effectivly shutting up this request, making it disapear from the logs.
- debug($message)
- Passes it's arguments to $logger->debug.
- info($message)
- Passes it's arguments to $logger->info.
- warn($message)
- Passes it's arguments to $logger->warn.
- error($message)
- Passes it's arguments to $logger->error.
- fatal($message)
- Passes it's arguments to $logger->fatal.
- is_debug()
- Calls $logger->is_debug.
- is_info()
- Calls $logger->is_info.
- is_warn()
- Calls $logger->is_warn.
- is_error()
- Calls $logger->is_error.
- is_fatal()
- Calls $logger->is_fatal.
- levels()
- This method does nothing but return ``0''. You should use Log::Log4perl's built in mechanisms for setting up log levels.
- enable()
- This method does nothing but return ``0''. You should use Log::Log4perl's built in mechanisms for enabling log levels.
- disable()
- This method does nothing but return ``0''. You should use Log::Log4perl's built in mechanisms for disabling log levels.
OVERRIDING CSPECS
Due to some fundamental design incompatibilities of Log::Log4perl and Catalyst::Log all cspecs of Log::Log4perl::Layout::PatternLayout that rely on call stack information fail to work as expected. Affected are the format strings %L, %F, %C, %M, %l and %T. You can instruct Catalyst::Log::Log4perl to try to hijack these patterns which seems to work reasonable well, but be advised that this feature is HIGHLY EXPERIMENTAL and relies on a few internals of Log::Log4perl that might change in later versions of this library. Additionally, this feature is currently only tested with Log::Log4perl version 1.08 allthough the underlying internals of Log::Log4perl seem to be stable since at least version 0.47.BUGS AND LIMITATIONS
The %T cspec of Log::Log4perl::Layout::PatternLayout is currently unimplemented. The implementation to get %M defies any logical approach but seems to work perfectly.AUTHORS
