Logging

The compiler constructor accepts a 3rd argument to define your own logger :

use ScssPhp\ScssPhp\Logger\LoggerInterface;

class Logger implements LoggerInterface
{
    public function warn($message, $deprecation = false)
    {
        //log a warning here
    }

    public function debug($message)
    {
        //log a debug message here
    }
}

$compiler = new Compiler([
    'publicFolder' => '/absolute/path/to/public/folder'
], [], new Logger);
