[Catalyst] RE: Log::Log4perl::Catalyst

[Anthony Gladdish]

Hi Duncan,

I overcame the hardcoding of filenames by storing them in the app config, like so:

In your MyApp.pm:

__PACKAGE__->setup;
__PACKAGE__->log( Log::Log4perl::Catalyst->new( __PACKAGE__->path_to(__PACKAGE__->config->{path_to_log4perl_conf})->stringify ) );

Then in the main app config:

path_to_log4perl_conf: 'Log4perl_prod.conf'
Log4Perl_filename: '/some/path/to/logfile.log'

Then in ./Log4perl_prod.conf (root of the Cat app):

log4perl.appender.LOGFILE.filename=sub { return MyApp->config->{Log4Perl_filename} }

Hope this helps,
Anthony Gladdish

Hi,

Has anybody got some examples about how to use this.

It looks like you just have to put the following lines in the main package before __PACKAGE__->setup():

use Log::Log4perl::Catalyst;
__PACKAGE__->log(Log::Log4perl::Catalyst->new('/path/to/log4perl.conf'));

That works up to a point in that the log messages are formatted as I want. However they always go to the STDERR and not to the file given in log4perl.conf. I've used the conf file in a test, so I know it works outside Catalyst. I'm using the Catalyst development server, does that over-ride the logger?

The other thing is that I don't really want to hardcode the filename. It should be in the application's conf file. However, if I just stick it in there as so:

 <Log4perl>
  conf_file /var/www/mymercedesservice.co.uk/fcgi/catalyst/mbfl2/lib/mbfl2/log4perl.conf
</Log4perl>

I can't access it via __PACKAGE__->config->{Log4perl}->{conf_file};
until after setup() has run.

Does that matter?

Thanks

Duncan
