Currently, this module writes Drupal 7 configuration, but not Drupal 8. To use the module effectively on Drupal 8 sites, we'll need to convert lines like:

$conf['site_name'] = 'My Drupal site';

$config['']['name'] = 'My Drupal site';

It's only the part before the equal sign that changes. So we should do the following:

  1. Use config instead of conf.
  2. Convert all instances of a new designated delimiter to ']['. I think ~ is a good choice because it's in the Unreserved Characters list.
  3. Update the documentation on the site config form, Variables, to explain use of the delimiter for Drupal 8 and include it in the examples.

May I suggest to also support $settings, which stores environment specific variables as explained in

It may be useful to set up a Redis backend for example.

To account for #2, $settings will be used instead of $config when the variable is not hierarchical (i.e. there are no tilde characters).

This will work in most cases, but not if you want to change the following, which are exceptions in that they are in fact hierarchical:

  • $settings['container_yamls']
  • $settings['trusted_host_patterns']

But you probably shouldn't be changing these anyway. So this is good enough for now.

Hello @colan,

Thanks for the commits.

I am currently testing it.

I don't think hierarchical $settings are exceptional. By example Redis use $settings in a hierarchical way:

I will see for a way to handle both cases.

Here is a patch that add a better support for $settings.

Now by prefixing the variable name with 'config||' or 'settings||' you can distingate the subsystem.

Thanks for the review.

Code looks great, thanks! I'll test this shortly.
