NAME

Log::ger::Format::MultilevelLog - Create a log($LEVEL, ...) subroutine/method

VERSION

version 0.042

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

DESCRIPTION

The Log::ger default is to create separate log_LEVEL subroutine (or LEVEL methods) for each level, e.g. log_trace subroutine (or trace method), log_warn (or 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 Bencher::Scenarios::Log::ger.

Note: the individual separate log_LEVEL subroutines (or LEVEL methods) are still installed, unless you specify configuration "exclusive" to true.

CONFIGURATION

sub_name

String. Defaults to log.

method_name

String. Defaults to log.

exclusive

Boolean. If set to true, will block the generation of the default log_LEVEL subroutines or LEVEL methods (e.g. log_warn, trace, ...).
