This module over-rides the default drupal loggers with it's own. This is to make the log dir structure a lot more useful. Instead of splitting logs by 'system.log' or 'debug.log' etc. it now does it by date (similar to FuelPHP).

The standard way to log in drupal would be to inject the class \Drupal\surflogger\LoggerService and then use the logging methods such as:

$this->log->error("Message here", ['array_key' => 'array_value']);

This would add your log message to a file in (for example): DRUPAL_ROOT/log/2017/12/31.log.

The module depends on the following; installing through composer will fetch these libraries if they dont already exist

"monolog/monolog"
"psr/log"

use Drupal\surflogger\LoggerService;
use Symfony\Component\DependencyInjection\ContainerInterface;

create a protected var

protected $log;

use di to add to constructor by

public function __construct(
  .....,
  LoggerService $loggerService
){
  ... = ...,
  $this->log = $loggerService;
}

dont forget to add to create

public static function create(ContainerInterface $container){
  return new static(
    ........,
    $container->get('surf.logger')    
  );
}
