=head1 NAME

Catalyst::Log - Catalyst Log Class

=head1 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 L<Catalyst>.

=head1 DESCRIPTION

This module provides the default, simple logging functionality for Catalyst.
If you want something different set C<< $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.

=head1 LOG LEVELS

=head2 debug

    $log->is_debug;
    $log->debug($message);

=head2 info

    $log->is_info;
    $log->info($message);

=head2 warn

    $log->is_warn;
    $log->warn($message);

=head2 error

    $log->is_error;
    $log->error($message);

=head2 fatal

    $log->is_fatal;
    $log->fatal($message);

=head1 METHODS

=head2 new

Constructor. Defaults to enable all levels unless levels are provided in
arguments.

    $log = Catalyst::Log->new;
    $log = Catalyst::Log->new( 'warn', 'error' );

=head2 level

Contains a bitmask of the currently set log levels.

=head2 levels

Set log levels

    $log->levels( 'warn', 'error', 'fatal' );

=head2 enable

Enable log levels

    $log->enable( 'warn', 'error' );

=head2 disable

Disable log levels

    $log->disable( 'warn', 'error' );

=head2 is_debug

=head2 is_error

=head2 is_fatal

=head2 is_info

=head2 is_warn

Is the log level active?

=head2 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');

=head2 _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.
