config()

With this method it's possible to load the configuration for your outputs.

The following options are valid:

config

With this option you can pass a file name or the configuration as a hash reference.

    $log->config(config => 'file.conf');
    # or
    $log->config(config => \%config);
    

plugin

With this option it's possible to say which plugin you want to use. Maybe you want to use the file extension "conf" with "YAML", which is reserved for the plugin "Config::General".

Examples:

    # this would use Config::General
    $log->config(
        config => 'file.conf'
    );
    # this would force .conf with YAML
    $log->config(
        config => 'file.conf',
        plugin => 'YAML'
    );
    

section

If you want to write the configuration into a global configuration file then you can create a own section for the logger:

    <logger>
        <file>
            filename = file.log
            minlevel = emerg
            maxlevel = warning
        </file>
        <screen>
            minlevel = emerg
            maxlevel = debug
        </screen>
    </logger>
    <another_script_config>
        foo = bar
        bar = baz
        baz = foo
    </another_script_config>
    

Now your configuration is placed in the "logger" section. You can load this section with

    $log->config(
        config  => 'file.conf',
        section => 'logger',
    );
    # or if you load the configuration yourself to %config
    $log->config(
        config  => \%config,
        section => 'logger',
    );
    # or just
    $log->config( config => $config{logger} );
    

Config structures

A very simple configuration looks like:

    $log->config(config => {
        file => {
            alias    => 'file1',
            filename => 'file1.log',
            maxlevel => 'info',
            minlevel => 'warn',
        },
        screen => {
            alias    => 'screen1',
            maxlevel => 'debug',
            minlevel => 'emerg',
        }
    });

Now, if you want to add another file-output then you can pass the outputs with a array reference:

    $log->config(config => {
        file => [
            {
                alias    => 'file1,
                filename => 'file1.log',
                maxlevel => 'info',
                minlevel => 'warn',
            },
            {
                alias    => 'file2',
                filename => 'file2.log',
                maxlevel => 'error',
                minlevel => 'emergency',
            }
        ],
        screen => {
            alias    => 'screen1',
            maxlevel => 'debug',
            minlevel => 'emerg',
        },
    });

It's also possible to pass the outputs as a hash reference. The hash keys "file1" and "file2" will be used as aliases.

    $log->config(config => {
        file => {
            file1 => {
                filename => 'file1.log',
                maxlevel => 'info',
                minlevel => 'warn',
            },
            file2 => {
                filename => 'file2.log',
                maxlevel => 'error',
                minlevel => 'emergency',
            }
        },
        screen => {
            alias    => 'screen1',
            maxlevel => 'debug',
            minlevel => 'emerg',
        },
    });

If you pass the configuration with the alias as a hash key then it's also possible to pass a section called "default". The options from this section will be used as defaults.

    $log->config(config => {
        file => {
            default => { # defaults for all file-outputs
                mode    => 'append',
            },
            file1 => {
                filename => 'file1.log',
                maxlevel => 'info',
                minlevel => 'warn',
            },
            file2 => {
                filename => 'file2.log',
                maxlevel => 'error',
                minlevel => 'emergency',
            }
        },
        screen => {
            alias    => 'screen1',
            maxlevel => 'debug',
            minlevel => 'emerg',
        },
    });
