How to set configuration parameter from console argument?

Question

I am new to symfony.

I am trying to change the formatting of the output Monolog file using the console argument 'format = json'.

In short, I want to run any console command as follows:

app/console my_command --format=json # xml / txt / my own

... and get the result of the LoggerInterface in the requested format.

For example, I set the default formatter in the configuration:

monolog:
    handlers:
        console:
            type:   console
            channels: [!event, !doctrine]
            formatter: json_formatter
services:
    json_formatter:
        class: Monolog\Formatter\JsonFormatter

When I create some MyEventListener :: onConsoleCommand ( as described here ), I cannot change the parameter package because it is already compiled: It is not possible to call set () on a frozen ParameterBag. "

Up2: My services configuration in this case is as follows:

services:
    kernel.listener.command_dispatch:
        class: My\Listener\MyEventListener
        autowire: true
        tags:
            - { name: kernel.event_listener, event: console.command }

On the other hand, I can register the console option in the source file:

# app/console
$loader = require __DIR__.'/autoload.php';
# ...
$application->getDefinition()->addOption(
    new InputOption(
        'formatter',
        'f',
        InputOption::VALUE_OPTIONAL,
        'The logs output formatter',
        'json_formatter'
    )
);

. $application- > getKernel() → getContainer() - .

, Symfony2 ?
