SYNOPSIS
use Log::Handler;
my $log = Log::Handler->new();
# Config::General
$log->config(config => 'file.conf');
# Config::Properties
$log->config(config => 'file.props');
# YAML
$log->config(config => 'file.yaml');
Or
use Log::Handler;
my $log = Log::Handler->new();
$log->config(
config => 'file.conf'
plugin => 'YAML',
);
DESCRIPTION
This module makes it possible to load the configuration from a file. The configuration type is determined by the file extension. It's also possible to mix file extensions with another configuration types.PLUGINS
Plugin name File extensions
------------------------------------------
Config::General cfg, conf
Config::Properties props, jcfg, jconf
YAML yml, yaml
If the extension is not defined then "Config::General" is used by default.
METHODS
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} );
PLUGINS
Config::General - inspired by the well known apache config format
Config::Properties - Java-style property files
YAML - optimized for human readability
EXAMPLES
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',
},
});
