On the Liip blog they've shared a new post from Tobias Schultze about a new feature that will be in the 2.4 release of the popular Symfony framework - the ability to show log messages in console output.
When you want to output text to the console you usually used the OutputInterface instance that is passed when your command gets executed. But there are two problems: it's cumbersome to print information depending on the verbosity settings and if the service you call also wants to give feedback you would need to pass on the $output. [...] To solve these [two problems] I thought it would be much easier to rely on the logger which is highly related. So I added integration between Symfonys Console Component and Symfonys logging library Monolog in PR #8167.
This gives you a new handler, the ConsoleHandler, that makes it easier to just write out based on console events instead of just appending to the output. It includes switches for verbosity levels too. He shows how to implement it in your application, configuring it through the YAML config both in the service and under the Monolog settings as a handler.
