This service provider makes it easy to show log messages from services in the console, without having to inject an instance of OutputInterface into the services. This requires version >=2.4 of Symfony Components. More info about the change is at the Symfony Blog.

In your console application, you can now do something like this:

use Symfony\Component\Console\Application;

$app = require 'app.php';
$console = new Application('My Console Application', '1.0');
// You should only register this service provider when running commands
$app->register(new \glen\ConsoleLoggerServiceProvider());

$console->addCommands(
    array(
    //...
    )
);

$console->run($app['console.input'], $app['console.output']);

You will still use the normal OutputInterface instance for command feedback in your commands, but you will now also get output from anything your services are logging.

The minimum logging level at which this handler will be triggered depends on the verbosity setting of the console output. The default mapping is:

• OutputInterface::VERBOSITY_NORMAL will show all WARNING and higher logs
• OutputInterface::VERBOSITY_VERBOSE (-v) will show all NOTICE and higher logs
• OutputInterface::VERBOSITY_VERY_VERBOSE (-vv) will show all INFO and higher logs
• OutputInterface::VERBOSITY_DEBUG (-vvv) will show all DEBUG and higher logs, i.e. all logs

This mapping can be customized with the logger.console_logger.handler.verbosity_level_map constructor parameter:

$app->register(new ConsoleLoggerServiceProvider(), [
    'logger.console_logger.handler.verbosity_level_map' => array(
        OutputInterface::VERBOSITY_QUIET => Logger::ERROR,
        OutputInterface::VERBOSITY_NORMAL => Logger::INFO,
        OutputInterface::VERBOSITY_VERBOSE => Logger::NOTICE,
        OutputInterface::VERBOSITY_VERY_VERBOSE => Logger::INFO,
        OutputInterface::VERBOSITY_DEBUG => Logger::DEBUG,
    ),
]);
