Unable to use environment variable for settings

[zeleznypa]

We need to get RabbitMQ host, port, etc. from environment variables

in neon we have:

extensions:
    rabbitmq: Kdyby\RabbitMq\DI\RabbitMqExtension

rabbitmq:
    connection:
        host: ::getenv(RABBITMQ_HOST)
        port: ::getenv(RABBITMQ_PORT)
        user: ::getenv(RABBITMQ_USER)
        password: ::getenv(RABBITMQ_PASSWORD)

But we give an assertion error that callback is not a valid string because of this

I don't think I wanna support this. You can do something like

<?php
return [
    'rabbitmq' => [
        'connection' => [
            'host' => getenv('RABBITMQ_HOST'),
        ]
    ]
];

and then register it in config

    includes:
        - rabbitmq.php

or use one of hundreds other ways to pass the ENV variable to the section.

Thanks for tip, how to include environment variables other way.

I just tried it "DG preferred way"

Unfortunately it is just because the validation of user and password. Whole other code fully support this way. I think, it will be more transparent, when whole configuration will be in one *.neon. file instead of including the PHP code.

How about this?
