Symfony2: Multi-level parameters in YML

Question

Here is what I want to do. I've got some yml file like...

My custom yml file :

# app/config/sv_parameters.yml
parameters:
  sv_email:
    debug: "debug@debug.com"
    admin: "admin@admin.com"
    ...

The config.yml file, importing my custom params :

# app/config/config.yml
imports:
  - { resource: sv_parameters.yml }
...

The config_dev.yml, importing the config.yml, and using a sub-parameter of my custom yml file :

# app/config/config_dev.yml
imports:
- { resource: config.yml }

swiftmailer:
  delivery_address: "%sv_email.debug%"

But, when I clear:cache :

You have requested a non-existent parameter "sv_email.debug".

I know in PHP multi-level parameters are arrays. But does that mean we can access them in pure YML ?

I could write my sv_email parameters inline, but that's not as clean as multi levels..

This is not possible to achieve in YML.
You have to move this nested variable to the upper level and then - include it in both needed places.

That's what I thought.. Do they plan to implement it in YML ? Because it would be much cleaner sometimes, instead of repeating `sv_email.debug` `sv_email.admin` `sv_email.client` ... – Bonswouar Aug 28 '13 at 13:15
@Bonswouar I have absolutely no idea :) – Vitalii Zurian Aug 28 '13 at 13:32

No chance. . is allowed in yaml parameters names so sv_email.client : value works just fine. Just no way to convert arrays to a dot notation without a massive bc break. – Cerad Aug 28 '13 at 14:53
On the other hand, the Symfony:DependencyInjection::load method allows you to add parameters to your container. So you could convert sv_email into individual parameters if you want. But I suspect you may find that to be more trouble than it's worth. – Cerad Aug 28 '13 at 14:56
