Domain specific Sprinkles loader for UserFrosting 4

This Sprinkle provides some "runtime" overloading for other Sprinkles.

This version requires UserFrosting 4.3 and up.

Why would you use such a thing?

You have a personal "core" Sprinkle ("portal") for your base logic
You have multiple Domains/URLs (portal.customer1.com, portal.customer2.net, portal.example.org, ...)
All Domains should use the same base logic but with different configurations
(other Layouts, other page titles, different databases, ...)

So you have two options:

Use a separate UserFrosting installation for each domain
Use this sprinkle and "share" one UserFrosting installation

Versions and UserFrosting support

UserFrosting Version	DomainSpecificSprinklesLoader Version
< 4.3.x	No Support
4.3.x	1.0.0

Installation

Edit UserFrosting app/sprinkles.json file and add the following to the require list : "ahaenggli/uf_domainspecificsprinklesloader": "^1.0.0". Also add DomainSpecificSprinklesLoader to the base list. For example:

{
    "require": {
        "ahaenggli/uf_domainspecificsprinklesloader": "^1.0.0"
    },
    "base": [
        "core",
        "account",
        "admin",
        "...", --> your base sprinkle
        "DomainSpecificSprinklesLoader"
    ]
}

Run composer update then php bakery bake to install the sprinkle.
Now you can edit the necessary configurations in your base Sprinkle and add your additional Sprinkles to load on "runtime".
Important: Each additional Sprinkle needs a sprinkles.json within.
Optional: You can add a /config/.env in each additional Sprinkle if you wanna change some environment variables.

How to use?

Edit your base sprinkle config/default.php and add the following variables:

'customUfInit' => ['whitelist'=>['portal.customer2.net', 'portal.example.org', ...] /* use your own domains here */,
                   'prefix_sprinkle_dir' => '' /* optional */],

'whitelist' is an array of your domains. Just these are checked whether there exists a Sprinkle or not.
Tip: you can use 'whitelist'=>['*'] to allow every domain. 'prefix_sprinkle_dir' is optional. You can add a prefix for your Sprinkles.

Now you can add additional sprinkles like: app/sprinkles/portal_customer2_net and app/sprinkles/portal_example_org

Usage example

base logic is in sprinkle awesome
you have 3 domains: portal.customer1.com, portal.customer2.net, portal.example.org
you wanna prefix something_ (because of alpha sort in your folder...)

Your app/sprinkles.json looks like:

{
    "require": {
        "ahaenggli/uf_domainspecificsprinklesloader": "^1.0.0"
    },
    "base": [
        "core",
        "account",
        "admin",
        "awesome", 
        "DomainSpecificSprinklesLoader"
    ]
}

(Run composer update and php bakery bake)

Your awesome Sprinkle config/default.php:

'customUfInit' => ['whitelist'=>['portal.customer1.net', 'portal.customer2.net', 'portal.example.org'],
                   'prefix_sprinkle_dir' => 'something_'],

Your app/sprinkles/ folder contains:

account
admin
awesome
core
DomainSpecificSprinklesLoader
something_portal_customer1_net
something_portal_customer2_net
something_portal_example_org

Your `app/sprinkles/something_portal_customer1_net/sprinkles.json' looks like:

{
    "base": [
        "awesome",
        "something_portal_customer1_net"
    ]
}

Your `app/sprinkles/something_portal_customer2_net/sprinkles.json' looks like:

{
    "base": [
        "awesome",
        "something_portal_customer2_net"
    ]
}

Your `app/sprinkles/something_portal_example_org/sprinkles.json' looks like:

{
    "base": [
        "awesome",
        "something_portal_example_org"
    ]
}

How does it work?

If the page is 'something_portal_example_org':

app/sprinkles.json is loaded
Sprinkle awesome (ServiceProvider) is loaded
Sprinkle DomainSpecificSprinklesLoader (ServiceProvider) is loaded
- app/sprinkles/something_portal_example_org/sprinkles.json is loaded
  (now .env for each entry is loaded, then each Sprinkle)
  - app/sprinkles/awesome/config/.env is loaded
  - app/sprinkles/something_portal_example_org/config/.env is loaded
  - $container['config'] is reinitialized
  - Sprinkle awesome (ServiceProvider) is loaded again (so first ServiceProvider-init of it is "overridden")
  - Sprinkle something_portal_example_org (ServiceProvider) is loaded
