Register Plugin

If you want to use default logger Bartlett\Reflect\Plugin\Log\DefaultLogger, skip this section.

If you want to use your own version of log plugin, use following pattern.

<?php

namespace YourNamespace;

use Bartlett\Reflect\Plugin\LogPlugin as BaseLogPlugin;

class LogPlugin extends BaseLogPlugin
{
    // all additional code you need
}

And the configuration in JSON file :

{
    "source-providers": [
    ],
    "plugins": [
        {
            "name": "Logger",
            "class": "YourNamespace\\LogPlugin",
            "options": []
        }
    ],
    "analysers" : [
    ],
    "services": [
    ]
}

Default logger

Use a solution similar to ErrorLogHandler of Monolog project.

{
    "source-providers": [
    ],
    "plugins": [
        {
            "name": "Logger",
            "class": "Bartlett\\Reflect\\Plugin\\LogPlugin",
            "options": []
        }
    ],
    "analysers" : [
    ],
    "services": [
    ]
}

It logs records at Psr\Log\LogLevel::INFO level or highter, identified by channel name DefaultLoggerChannel.

Using your private logger

Use your own logger, that must be compatible PSR-3.

<?php

namespace YourNamespace;

use Psr\Log\AbstractLogger;

class YourLogger extends AbstractLogger
{
    public function log($level, $message, array $context = array())
    {
    }
}

And identify it in the JSON config file, as follow

{
    "source-providers": [
    ],
    "plugins": [
        {
            "name": "Logger",
            "class": "YourNamespace\\LogPlugin"
        }
    ],
    "analysers" : [
    ],
    "services": [
    ]
}

Or even

{
    "source-providers": [
    ],
    "plugins": [
        {
            "name": "Logger",
            "class": "Bartlett\\Reflect\\Plugin\\LogPlugin",
            "options": "YourNamespace\\YourLogger"
        }
    ],
    "analysers" : [
    ],
    "services": [
    ]
}

Using Monolog

Use one of the most famous logging solution compatible PSR-3.

If you want to use Monolog with CompatInfo on CLI mode, then you should use a wrapper like this.
<?php

namespace YourNamespace;

use Monolog\Logger;
use Monolog\Handler\StreamHandler;

class YourLogger extends Logger
{
    public function __construct($name = 'YourLoggerChannel')
    {
        $stream = new StreamHandler('/var/logs/phpcompatinfo.log');
        parent::__construct($name, array($stream));
    }
}

And with JSON config file as follow

{
    "source-providers": [
    ],
    "plugins": [
        {
            "name": "Logger",
            "class": "Bartlett\\Reflect\\Plugin\\LogPlugin",
            "options": "YourNamespace\\YourLogger"
        }
    ],
    "analysers" : [
    ],
    "services": [
    ]
}
