# ABSTRACT: Create a log($LEVEL, ...) subroutine/method

=head1 NAME
Log::ger::Format::MultilevelLog - Create a log($LEVEL, ...) subroutine/method
=head1 VERSION
version 0.042
=head1 SYNOPSIS
To use for the current package:
use Log::ger::Format MultilevelLog => (
# sub_name => 'log_it', # optional, defaults to 'log'
# method_name => 'log_it', # optional, defaults to 'log'
# exclusive => 1, # optional, defaults to 0
);
use Log::ger;
log('warn', 'This is a warning');
log('debug', 'This is a debug, data is %s', $data);
log_warn "This is also a warning"; # still available, unless you set exclusive to 1
=head1 DESCRIPTION
The Log::ger default is to create separate C<log_LEVEL> subroutine (or C<LEVEL>
methods) for each level, e.g. C<log_trace> subroutine (or C<trace> method),
C<log_warn> (or C<warn>), and so on. But sometimes you might want a log routine
that takes $level as the first argument. That is, instead of:
log_warn('blah ...');
or:
$log->debug('Blah: %s', $data);
you prefer:
log('warn', 'blah ...');
or:
$log->log('debug', 'Blah: %s', $data);
This format plugin can create such log routine for you.
Note: the multilevel log is slightly slower because of the extra argument and
additional string level -> numeric level conversion. See benchmarks in
L<Bencher::Scenarios::Log::ger>.
Note: the individual separate C<log_LEVEL> subroutines (or C<LEVEL> methods) are
still installed, unless you specify configuration L</exclusive> to true.
=for Pod::Coverage ^(.+)$
=head1 CONFIGURATION
=head2 sub_name
String. Defaults to C<log>.
=head2 method_name
String. Defaults to C<log>.
=head2 exclusive
Boolean. If set to true, will block the generation of the default C<log_LEVEL>
subroutines or C<LEVEL> methods (e.g. C<log_warn>, C<trace>, ...).
