Referencing "real" env var with dump-env

[DavG]

Hello,

Suppose I have in my etc/environment DEFAULT_APP_CDN=https://cdn.somewhere.com

In Flex 1.2.0, I can write in my .env
APP_CDN=${DEFAULT_APP_CDN}
Then with
composer symfony:dump-env whatever
I got in .env.local.php
'APP_CDN' => 'https://cdn.somewhere.com'
And that's pretty cool.

But starting with Flex 1.2.1, I got
'APP_CDN' => ''

Was it not supposed to work from the start ?
Is there another solution to do this ?

Thx

That's desired behavior: dump-env is context-free.
If that doesn't work for you, you can create your own dumping logic.

So it was a bug in 1.2.0, fixed but undocumented. That's a breaking change for me :(

Ok, I will do my own.

@nicolas-grekas I see this still works without dump-env (ie only with .env), I can reference a real environment variable in my .env
APP_CDN=${DEFAULT_APP_CDN}

Then in PHP, $_ENV['APP_CDN'] / $_SERVER['APP_CDN'] has the real value.

Can you tell me if it's the desired behavior, in this case ?
Or is it going to break in a future release ?

Thanks.
