=head1 NAME
Dancer::Logger - common interface for logging in Dancer
=head1 DESCRIPTION
This module is the wrapper that provides support for different
logger engines.
=head1 USAGE
=head2 Default engine
The setting B<logger> defines which logger engine to use.
If this setting is not set, logging will not be available in the application
code.
Dancer comes with the logger engines L<Dancer::Logger::File> and
L<Dancer::Logger::Console>, but more are available on the CPAN.
=head2 Configuration
The B<logger> configuration variable tells Dancer which engine to use.
You can change it either in your config.yml file:
# logging to console
logger: "console"
Or in the application code:
# logging to file
set logger => 'file';
The log format can also be configured,
please see L<Dancer::Logger::Abstract/"logger_format"> for details.
=head2 Auto-serializing
The loggers allow auto-serializing of all inputs:
debug( 'User credentials: ', \%creds );
Will provide you with an output in a single log message of the string and the
reference dump.
=head1 AUTHORS
This module has been written by Alexis Sukrieh. See the AUTHORS file that comes
with this distribution for details.
=head1 LICENSE
This module is free software and is released under the same terms as Perl
itself.
=head1 SEE ALSO
See L<Dancer> for details about the complete framework.
You can also search the CPAN for existing engines in the Dancer::Logger
namespace : L<http://search.cpan.org/search?query=Dancer%3A%3ALogger>.
